      摘要:Seeds are the source for the production of Chinese medicinal materials. The seed authenticity and quality of directly affect the effectiveness and safety of Chinese medicinal materials. The seed quality is faced with the problems such as mixed sources, existence of adulterants and seeds stocked for years, low maturity, and low purity. To ensure the high-quality and sustainable development of the Chinese medicinal material industry, it is urgent to standardize the seed market and identify and evaluate the quality of the seeds circulating in the market. Seed identification methods include visual inspection, microscopic observation, micro-character identification, chemical fingerprinting, molecular identification, electronic nose, X-ray diffraction, electrochemical fingerprinting, spectral imaging, and artificial intelligence. These methods have different application scopes and unique advantages and disadvantages. According to the different species of Chinese herbal medicines and different requirements of testing sites, suitable methods can be selected to achieve rapid and accurate identification with low costs. In the future, the seed identification methods should be developed based on emerging technologies with interdisciplinary knowledge, and intelligent, nondestructive, and single-grain detection methods are needed for the modern Chinese medicinal material industry. This paper introduces the seed identification technologies currently applied in research and production, compares the principles, applicability, advantages, and disadvantages of different technologies, and provides an outlook on the future development of seed identification technologies, aiming to provide a reference for the identification and quality evaluation of seeds of Chinese medicinal material.

      摘要:In the quality control of Chinese medicine, the detection of active components and toxic and harmful components are two important links. Although conventional methods such as high performance liquid chromatography and liquid chromatography-mass spectrometry can accurately quantify the above substances, they have shortcomings such as complicated operation, high costs, inability of detection at any time, difficult detection of insoluble and macromolecular substances. Enzyme-linked immunosorbent assay (ELISA) can adsorb antigens or antibodies on the surface of solid carriers and realize qualitative or quantitative analysis of targets by using the specific reactions of antigens and antibodies. This method is praised for the simple operation, high sensitivity, strong specificity, simple requirements for experimental equipment, a wide application range, and low costs. In recent years, ELISA has been widely used in the quality control of Chinese medicine, especially in the content determination of mycotoxins represented by aflatoxin and the qualitative and quantitative analysis of active components. ELISA plays an increasingly important role with its unique advantages, providing new methods and ideas for the rapid quality examination of large quantities of Chinese medicines. This paper reviews the research progress in ELISA for the quality control of Chinese medicine in recent years and prospects its technical development and application prospects, aiming to provide reference and research ideas for further using this method to ensure the quality, safety, and controllability of Chinese medicine.

      摘要:ObjectiveTo establish a rapid method for evaluating the heterozygosity of Murraya paniculata germplasm materials and provide as a foundation for developing germplasm breeding and innovation measures for M. paniculata.MethodSingle nucleotide polymorphisms (SNPs) were screened from the genome resequencing data of 65 plants of M. paniculata. A self-written script was used to transform 20 SNPs into restriction fragment length polymorphism (RFLP) markers. Polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) was employed to detect the 20 RFLP markers in 12 M. paniculata germplasm accessions, and the heterozygosity of M. paniculata germplasm accessions was calculated based on the number of enzyme-cutting bands at the 20 RFLP marker sites. Plink was used to calculate the whole genome heterozygosity of 12 M. paniculata germplasm accessions, and the results obtained with different methods were compared.ResultThere was no significant difference in the heterozygosity calculated by the PCR-RFLP method and the genome resequencing method. The PCR-RFLP and genome resequencing methods identified 8 and 9 germplasm accessions, respectively, with a heterozygosity level less than 30%. Seven germplasm accessions with heterozygosity less than 30.00% were calculated by both methods.ConclusionThe PCR-RFLP method established in this study for evaluating the heterozygosity of M. paniculata germplasm demonstrates the precision of 87.5% and the accuracy of 77.8%. This method serves as a reference for developing heterozygosity evaluation methods in other medicinal plant germplasm resources.

      摘要:ObjectiveTo identify Lycium chinense and L. barbarum as the original plants of Lycii Cortex simply and efficiently by multiple allele-specific polymerase chain reaction (PCR).MethodThe chloroplast genome sequences of L. chinense and L. barbarum were downloaded from the Chloroplast Genome Information Resource (CGIR), and then IdenDSS was employed to screen out the specific single nucleotide polymorphism (SNP) sites between the two plants. Primer 5.0 was used to design the specific primers, including primers GQ-F/R for identifying L. chinense and primers NX-F/R for identifying L. barbarum. Furthermore, the primer concentration ratio, annealing temperature, cycles, and Taq enzyme were optimized to establish the optimal PCR system and conditions for plant identification. Finally, the applicability of the established method was examined with the plant samples collected from different regions.ResultThe PCR with GQ-F/R∶NX-F/R concentration ratio of 2∶1 at the annealing temperature at 59 ℃ and for 30 cycles showed specific bands at 183 bp and 295 bp, respectively, for L. chinense and L. barbarum samples from different regions.ConclusionThe established PCR approach can simply, rapidly, and efficiently identify the original plants of Lycii Cortex, serving as a new method for the discrimination between L. chinense and L. barbarum. Moreover, the method provides technical support for the research and development of classic famous prescriptions containing Lycii Cortex.

      摘要:By consulting the ancient and moderm literature, this paper makes a textual research on the name, origin, quality evaluation, harvesting and processing of Olibanum, so as to provide a basis for the development of the famous classical formulas containing this medicinal material. According to the herbal textual research, the results showed that Olibanum was first described as a medicinal material by the name of Xunluxiang in Mingyi Bielu(《名医别录》), until Ruxiang had been used as the correct name since Bencao Shiyi(《本草拾遗》) in Tang dynasty. The main origin was Boswellia carterii from Burseraceae family. The mainly producing areas in ancient description were ancient India and Arabia, while the modern producing areas are Somalia, Ethiopia and the southern Arabian Peninsula. The medicinal part of Olibanum in ancient and modern times is the resin exuded from the bark, which has been mainly harvested in spring and summer. It is concluded that the better Olibanum has light yellow, granular, translucent, no impurities such as sand and bark, sticky powder and aromatic smell. There were many processing methods in ancient times, including cleansing(water flying, removing impurities), grinding(wine grinding, rush grinding), frying(stir-frying, rush frying, wine frying), degreasing, vinegar processing, decoction. In modern times, the main processing methods are simplified to cleansing, stir-frying and vinegar processing. Nowadays, the commonly used specifications include raw, fried and vinegar-processed products. Among the three specifications, raw products is the Olibanum after cleansing, fried products is a kind of Olibanum processed by frying method, vinegar-processed products is the processed products of pure frankincense mixed with vinegar. Based on the research results, it is recommended to select the resin exuded from the bark of B. carterii for the famous classical formulas such as Juanbitang containing Olibanum, processing method should be carried out in accordance with the processing requirements of the formulas, otherwise used the raw products if the formulas without clear processing requirements.

      摘要:By consulting ancient and modern literature, the herbal textual research of Farfarae Flos has been conducted to verify the name, origin, producing area, quality evaluation, harvesting and processing methods, so as to provide reference for the development and utilization of the famous classical formulas containing Farfarae Flos. According to the research, the results showed that Farfarae Flos was first described as a medicinal material by the name of Kuandonghua in Shennong Bencaojing(《神农本草经》), and the name was used and justified by later generations. The main origin was the folwer buds of Tussilago farfara, in addition, the flower buds of Petasites japonicus were used as medicine in ancient times. The ancient harvesting time of Farfarae Flos was mostly in the twelfth month of the lunar calendar, and the modern harvesting time is in December or before the ground freeze when the flower buds have not been excavated. Hebei, Gansu, Shaanxi are the authentic producing areas with the good quality products. Since modern times, its quality is summarized as big, fat, purple-red color, no pedicel is better. Processing method from soaking with licorice water in the Northern and Southern dynasties to stir-frying with honey water followed by micro-fire in the Ming dynasty, and gradually evolved to the modern mainstream processing method of honey processing. Based on the research results, it is suggested that the dried flower buds of T. farfara, a Compositae plant, should be selected for the development of famous classical formulas containing Farfarae Flos, and the corresponding processed products should be selected according to the specific processing requirements of the formulas, and raw products are recommended for medicinal use without indicating processing requirements.

      摘要:In order to provide basic information for the utilization and development of famous classical formulas containing Bletillae Rhizoma, this article systematically analyzes the historical evolution of the name, origin, harvesting and processing of Bletillae Rhizoma by reviewing the ancient materia medica, prescription books, medical books and modern literature. The research results showed that Baiji(白及) was the main name, some scholars took Baiji(白芨) as its main name, and there were many other names such as Baiji(白给), Baigen(白根), Baiji(白苙). The mainstream source of Bletillae Rhizoma was the tubers of Bletilla striata, and drying, large, white, solid, root-free and skin removed completely were the good quality standards. With the promotion of wild to cultivated medicinal materials, there were certain differences between their traits, and the quality evaluation indexes should be adjusted accordingly. The origin of records in the past dynasties was widely distributed, with Guizhou and Sichuan having high production and good quality in modern times. The harvesting period is mostly in spring and autumn, and harvested in autumn was better. The processing and processing technology is relatively simple, and it was used fresh or powdered in past dynasties, while it is mainly sliced for raw use in modern times. Based on the results, it is suggested that the tubers of Bletilla striata of Orchidaceae should be used in the famous classical formulas, and it should be uniformly written as Baiji(白及). And if the original formula indicates the requirement of processing, it should be operated according to the requirement, if the requirement of processing is not indicated, it can be used in raw form as medicine.

      摘要:This article systematically analyzes the historical evolution of the origin, scientific name, medicinal parts, quality evaluation, harvesting and processing and other aspects of Tsaoko Fructus by consulting ancient materia medica, medical books, prescription books in the past dynasties and combining with the modern literature, so as to provide a basis for the development and utilization of famous classical formulas containing Tsaoko Fructus. According to the research, the name of Caoguo(草果) was first used in the Taiping Huimin Heji Jufang(《太平惠民和剂局方》) in the Northern Song dynasty, Tsaoko Fructus is the correct name of the herbal medicine in all dynasties, and there are also aliases such as Caokou, Doukou, Loukou, Laokou and Caodoukou. The mainstream source of Tsaoko Fructus used in the past dynasties is the dried mature fruit of Amomum tsaoko of Zingiberaceae, but Tsaoko Fructus was often used as a nickname for Amomi Fructus Rotundus or Alpiniae Katsumadai Semen during the Song dynasty. Bencao Pinhui Jingyao(《本草品汇精要》) in the Ming dynasty was the earliest materia medica that recorded Tsaoko Fructus as a separate medicinal herb in sections. Under the influence of early ancient books, there were some books that confused Tsaoko Fructus with other Zingiberaceae plants during the Qing dynasty, it was not until modern times that Tsaoko Fructus was distinguished from other plants. The origin of Tsaoko Fructus is Yunnan and Guangxi, and then gradually expanded to Guizhou and other places. Now Yunnan is the province with the largest planting area of Tsaoko Fructus, and has become the main producing area. Since modern times, it has been recorded in the literature that the quality of Tsaoko Fructus is mainly characterized by large, full, red-brown and strong in smell. According to ancient records, the harvest time of Tsaoko Fructus was in the eighth month of the lunar calendar, and they were mostly used for peeling or simmering. Currently, the harvest period of Tsaoko Fructus is October to November, and then sun-dried or dried after harvesting. The records of the properties and functional indications of Tsaoko Fructus are basically consistent with the ancient and modern documents, which is warm in nature, pungent in flavor, belonging to the spleen and stomach meridians, moderate in dryness and dampness, intercepting malaria and eliminating phlegm, used for internal resistance of cold and dampness, abdominal distension and pain, fullness and vomiting, malaria cold and fever, and plague fever. Based on the research results, it is suggested that A. tsaoko should be used as the medicinal base for the development of famous classical formulas containing Tsaoko Fructus, processing method can be according to the requirements of the prescription, and if the requirements of concoction are not indicated, it can be used in the form of raw products.

      摘要:ObjectiveTo observe the effects of Youguiwan on bone metabolism and bone morphogenetic protein-2 (BMP-2)/Smad signaling pathway in ovaries-removed rats with osteoporosis and study the mechanism of Youguiwan in the prevention and treatment of osteoporosis.MethodA postmenopausal rat model of osteoporosis was prepared by bilateral ovariectomy. The 40 female SD rats were randomly divided into five groups, including sham operation group, model group, alendronate sodium group (0.1 mg·kg-1), and high-dose and low-dose (5.36 and 2.68 g·kg-1 groups of Youguiwan. The drug was given seven days after modeling, once a day for 12 weeks. After the treatment, the changes in femur tissue structure were observed by micro-CT, including bone mineral density (BMD), bone volume/total volume (BV/TV), trabecular number (Tb.N), trabecular thickness (Tb.Th), bone surface/bone volume (BS/BV), and trabecular separation (Tb.Sp). Ossification was observed by saffrane-solid green staining, and serum levels of bone metabolism markers, including bone alkaline phosphatase (BALP), osteocalcin (BGP), type Ⅰ procollagen amino terminal propeptide (PINP), and tartrate-resistant acid phosphatase 5b (TRACP-5b), were determined by enzyme-linked immunosorbent assay (ELISA). The protein and mRNA expression levels of Runx2, BMP-2, and Smad1 in rat femur were detected by Western blot and Real-time fluorescence quantitative polymerase chain reaction (Real-time PCR).ResultCompared with the sham operation group, bone trabecula in the model group was sparse. BMD, BV/TV, Tb.N, and Tb.Th were decreased (P<0.05, P<0.01). BS/BV (P<0.05) and Tb.Sp were increased. The content of BGP, BALP, PINP, and TRACP-5b in serum was significantly increased (P<0.01). The mRNA and protein expressions of Runx2, BMP-2, and Smad1 in rat femur were significantly decreased (P<0.05, P<0.01). Compared with the model group, the number of bone trabeculae in the high-dose and low-dose groups of Youguiwan was increased, and the bone microstructure was improved. BMD, BV/TV, Tb.N, and Tb.Th were increased significantly (P<0.05, P<0.01), and BS/BV and Tb.Sp were increased. The content of bone metabolic markers decreased (P<0.05, P<0.01).ConclusionYouguiwan has certain preventive and therapeutic effects on postmenopausal osteoporosis, and its mechanism may be related to promoting bone formation by regulating the BMP-2/Smad signaling pathway.

      摘要:ObjectiveTo investigate the mechanism of Biejiajian Wan in the intervention of primary liver cancer based on long non-coding RNA SNHG5 (lncRNA SNHG5)/micro RNA-26a-5p (miRNA-26a-5p)/glycogen synthase kinase-3β (GSK-3β) signal axis.MethodDouble luciferase reporting assay was used to verify the targeted interaction between lncRNA SNHG5 and miRNA-26a-5p, miRNA-26a-5p, and GSK-3β in HepG2 cells. Nude-mouse transplanted tumor model of human HepG2 were established and randomly divided into model group, Biejiajian Wan low-dose group (0.5 g·kg-1), medium-dose group (1.0 g·kg-1), and high-dose group (2.0 g·kg-1), and sorafenib group (100 mg·kg-1), with 10 mice in each group. The mice were given intragastric administration of normal saline or drug for 28 days, and the tumor volume was measured at different time. Hematoxylin-eosin (HE) staining was used to observe the histological changes of tumors. The nucleic acid levels of lncRNA SNHG5, miRNA-26a-5p, GSK-3β, and β-catenin mPNA in tumor tissue were detected by real-time quantitative polymerase chain reaction (Real-time PCR). The protein expression levels of GSK-3β and β-catenin in tumor tissue were detected by western blot.ResultCompared with the SNHG5-WT (wild type) + miRNA NC (negative control) group, the relative luciferase activities of the SNHG5-WT + miRNA-26a-5p mimic group were decreased (P<0.05). Compared with the GSK-3β-WT + miRNA NC group, the relative luciferase activity of the GSK-3β-WT + miRNA-26a-5p mimic group was decreased (P<0.05). Compared with the model group, the tumor volume of Biejiajian Wan low-dose, medium-dose, and high-dose groups was significantly decreased (P<0.05, P<0.01). Compared with the model group, the cells in the tumor tissue of nude mice in each dose group of Biejiajian Wan were sparsely arranged with necrocytosis, which showed concentration-dependent changes. Compared with the model group, the expression levels of lncRNA SNHG5, GSK-3β, and β-catenin were decreased (P<0.05, P<0.01), while the expression of miRNA-26a-5p was increased in each dose group of Biejiajian Wan (P<0.05, P<0.01). Compared with the model group, the protein expression levels of GSK-3β and β-catenin were decreased in each dose group of Biejiajian Wan (P<0.05, P<0.01).ConclusionBiejiajian Wan may affect the necrosis of liver cancer cells through lncRNA SNHG5/miRNA-26a-5p/GSK-3β signal axis and thus play an anti-tumor role. This research will provide more theoretical basis for the clinical application of Biejiajian Wan.

      摘要:ObjectiveTo study whether Chaihu Longgu Mulitang can inhibit hypothalamic inflammation, mitigate anxiety-like behavior, and alleviate anxiety symptoms by regulating the p38 mitogen-activated protein kinase/nuclear factor-κB (p38 MAPK/NF-κB) signaling pathway in the rat model of generalized anxiety disorder (GAD).MethodTwelve out of 74 Wistar rats were randomly selected as the blank group, and the remaining rats were subjected to chronic restraint stress for the modeling of GAD. The open field test (OFT) and elevated Porteus maze test (PMT) were conducted 14 days after modeling to detect the anxiety-like behaviors. Sixty successfully modeled rats were selected and randomized into model, low-, medium-, and high-dose (6, 12, and 24 g·kg-1, respectively) Chaihu Longgu Mulitang, and diazepam (1 mg·kg-1) groups (n=12) and administrated with corresponding drugs for 14 consecutive days. OFT and PMT were then carried out to examine the anxiety-like behaviors of the rats. The levels of tumor necrosis factor-α (TNF-α), interleukin-6 (IL-6), and interleukin-1β (IL-1β) in the hypothalamus and serum of rats were determined by the enzyme-linked immunosorbent assay (ELISA). Real-time fluorescence quantitative polymerase chain reaction (Real-time PCR)was conducted to determine the mRNA levels of p38 MAPK, NF-κB p65, nuclear factor κB inhibitor α (IκBα), and ionized calcium binding adaptor molecule 1 (Iba-1). The protein levels of p38 MAPK, phosphorylated (p)-p38 MAPK, NF-κB p65, p-NF-κB p65, and IκBα in the hypothalamus of rats were determined by Western blot. The expression of Iba-1 in the hypothalamic microglia was detected by immunofluorescence assay.ResultCompared with the blank group, the model group had decreased body weight, scattered dark yellow fur, increased irritability, and preference to hibernation in the corner. In addition, the modeled rats showed increased edge movement distance and time in OFT (P<0.01) and decreased movement distance and time and the number of entries in the open arm in PMT (P<0.01). The modeling increased the fluorescence intensity of Iba-1 in paraventricular nucleus of hypothalamus (P<0.01), elevated the levels of IL-1β, IL-6, and TNF-α in the serum and hypothalamus (P<0.01), up-regulated the protein and mRNA levels of p38 MAPK, NF-κB p65, p-p38 MAPK, p-NF-κB p65, and Iba-1 (P<0.05, P<0.01), and down-regulated the protein and mRNA levels of IκBα (P<0.01) in the hypothalamus. Compared with the model group, medium- and high-dose Chaihu Longgu Mulitang and diazepam increased the body weight, improved the fur and behaviors, decreased the edge movement distance and time in OFT (P<0.05, P<0.01), and increased the movement distance and time in the open arm in PMT (P<0.05, P<0.01). Furthermore, they decreased the fluorescence intensity of Iba-1 in hypothalamic microglia (P<0.05, P<0.01), lowered the levels of IL-1β, IL-6, and TNF-α in the serum and hypothalamic tissue (P<0.05, P<0.01), down-regulated the mRNA and protein levels of p38 MAPK, NF-κB p65, p-p38 MAPK, p-NF-κB p65, and Iba-1 (P<0.05, P<0.01), and up-regulated the mRNA and protein levels of IκBα (P<0.05, P<0.01) in the hypothalamus.ConclusionChaihu Longgu Mulitang can mitigate anxiety-like behaviors and relieve anxiety in GAD rats by inhibiting the p38 MAPK/NF-κB signaling pathway and reducing the activation of microglia and the levels of pro-inflammatory cytokines in the hypothalamus.

      摘要:ObjectiveTo observe the effect of Qingfei Huatan Zhuyu decoction on the lung and intestinal function of rats with chronic obstructive pulmonary diseases (COPD) and explore the deep-seated mechanism of its embodiment of lung and intestinal co-treatment.MethodA total of 60 Wistar rats were randomly divided into six groups, with 10 rats in each group, and the groups were control group, model group, acute syrup group (10 g·kg-1·d-1), and low, medium, and high-dose groups (10, 15, 20 g·kg-1·d-1) of Qingfei Huatan Zhuyu decoction. The COPD rat model was established by lipopolysaccharide tracheal drip combined with the smoke inhalation method, and the acute syrup group and the Qingfei Huatan Zhuyu decoction group were administered by gavage with corresponding dose concentrations respectively, while the rest groups were controlled by saline gavage, and the lung function and blood gas indexes of rats were monitored after the last administration. The histopathological changes in the lung and intestine were observed microscopically. The expression of serum interleukin-6 (IL-6), tumor necrosis factor-α (TNF-α), and secretory immunoglobulin A (IgA) in colon tissue were measured by enzyme-linked immunosorbent assay (ELISA). The biochemical indexes such as serum diamine oxidase (DAO), D-lactic acid, and malondialdehyde (MDA) were measured. Immunohistochemistry was used to detect the expression of tight junction protein (Occludin) in rat colon tissue. The expression of F4/80 positive alveolar macrophages in rat lung tissue, and the expression of α-actin (α-SMA) and colonic atresia small band protein-1 (ZO-1) were determined by immunofluorescence. The protein expression of p-NF-κB p65, NF-κB p65, p-p38 MAPK, and p-p38 MAPK and the expression of Occludin and ZO-1 in colon tissue were detected in rat lung tissue by Western blot.ResultCompared with the normal group, the model group had pulmonary dysfunction, reduced forced vital capacity (FVC), arterial partial oxygen pressure (PaO2), arterial oxygen saturation (SaO2), and dynamic lung compliance (Cdyn) (P<0.01), and the pathological changes in the lung and intestine were obvious. The expressions of IL-6, TNF-α, DAO, D-lactic acid, and MDA in serum were increased (P<0.05,P<0.01), and the protein expression ratio of p-NF-κB p65/NF-κB p65 and p-p38 MAPK/p38 MAPK in lung tissue was increased. The expression of F4/80 positive macrophages in lung tissue was enhanced. The expression of IgA, Occludin, and ZO-1 in colon tissue decreased (P<0.05,P<0.01). Compared with the model group, the pulmonary function of the rats in the acute syrup group and groups of Qingfei Huatan Zhuyu decoction was significantly improved, and the FVC, PaO2, SaO2, and Cdyn were increased (P<0.05, P<0.01). The pathological changes in the lung and intestine were significant. The expressions of IL-6, TNF-α, DAO, D-lactic acid, and MDA in serum were decreased (P<0.05,P<0.01), and the expressions of F4/80 positive macrophages in lung tissue were decreased (P<0.01). The protein expression ratio of p-NF-κB p65/NF-κB p65 and p-p38 MAPK/p38 MAPK in lung tissue decreased (P<0.01), and the expression of IgA, Occludin, and ZO-1 in colon tissue increased (P<0.01).ConclusionQingfei Huatan Zhuyu decoction can effectively reduce the symptoms of COPD rats, and its mechanism of action is related to inhibiting the inflammatory response of lung tissue and improving the barrier function of the intestinal mucosa.

      摘要:ObjectiveTo explore the establishment and evaluation methods of the rat model of acute myocardial infarction (AMI) in coronary heart disease with the syndrome of Qi and Yin deficiency by sleep deprivation (SD) combined with isoproterenol (ISO) and preliminarily explore its biological basis.MethodForty SD rats were assigned into normal (no treatment), SD (treatment in modified multi-platform water environment for 96 h), ISO (subcutaneous injection of ISO at 100 mg·kg-1 once every other day for a total of 2 times), and SD+ISO (injection of 100 mg·kg-1 ISO after SD for 72 h and 96 h) groups. The cardiac function was detected by small animal echocardiography. The serum levels of creatine kinase (CK), creatine kinase isoenzyme (CK-MB), lactate dehydrogenase (LDH), and cardiac troponin T (cTnT) were measured by biochemical methods. The pathological changes of the myocardial tissue were observed by hematoxylin-eosin staining. The general state, body weight, grip strength, body temperature, behaviors in open field test, serum levels of cyclic adenosine monophosphate (cAMP), cyclic guanosine monophosphate (cGMP), cAMP/cGMP ratio, red (R), green (G), blue (B) values of the tongue surface, and pulse amplitude were observed and measured to evaluate the modeling results. Enzyme-linked immunosorbent assay was employed to determine the serum levels of interleukin-18 (IL-18), tumor necrosis factor-α (TNF-α), superoxide dismutase (SOD), malondialdehyde (MDA), corticotropin-releasing factor (CRF), adrenocorticotropic hormone (ACTH), triiodothyronine (T3), tetraiodothyronine (T4), cluster of differentiation 4 (CD4), and cluster of differentiation 8 (CD8).ResultIn terms of disease indicators, the ISO and SD+ISO groups had lower cardiac function indicators than the normal group (P<0.01). The levels of CK, CM-MB, LDH and cTnT elevated in each model group compared with the normal group (P<0.01). The pathological changes of myocardial tissue were obvious in the ISO and SD+ISO groups. In terms of syndrome indicators, compared with the normal group, the SD and SD+ISO groups showed decreased body weight at each time point (P<0.01), and the ISO group showed decreased body weight at the time points of 48 h and 72 h (P<0.05, P<0.01). The paw temperature and rectal temperature increased in the SD group (P<0.01). The model groups showed weakened grasp strength, lowered R, G, and B values of the tongue surface (P<0.01), prolonged immobility time (P<0.01), reduced total distance and number of entering the central area (P<0.01), decreased average speed (P<0.05, P<0.01), and increased cAMP and cGMP (P<0.05, P<0.01). The cAMP/cGMP ratio was increased in the SD+ISO group (P<0.01), and the pulse amplitude was decreased in the SD and SD+ISO groups (P<0.01). In terms of serological indicators,compared with the normal group, the levels of IL-18, TNF-α, SOD and MDA were significantly increased in the ISO and SD+ISO groups (P<0.01), the CRF, ACTH, CORT, T3, T4, CD4 and CD8 in the model groups were increased (P<0.05, P<0.01).ConclusionSleep deprivation for 96 h combined with high-dose ISO can successfully establish a rat model of acute myocardial infarction in coronary heart disease with the syndrome of Qi and Yin deficiency. The model evaluation system can be built with disease indicators of western medicine, histopathological indicators, macroscopic indicators of traditional Chinese medicine, and serological indicators.

      摘要:ObjectiveTo study the effect and mechanism of Yixintai on mitochondrial fission proteins in the rat model of chronic heart failure.MethodTen of 60 SD rats were randomly selected as the sham operation group, and the remaining 50 rats were subjected to ligation of the left anterior descending coronary artery for the modeling of heart failure post myocardial infarction. The successfully modeled rats were randomized into model, low-, medium-, and high-dose (1.4, 2.8, and 5.6 g·kg-1, respectively) Yixintai, and trimetazidine (10 mg·kg-1) groups. The rats were administrated with corresponding doses of drugs by gavage, and the rats in the model group and sham operation group were given an equal volume of normal saline by gavage for 28 consecutive days. Enzyme-linked immunosorbent assay (ELISA) was then employed to measure the levels of amino-terminal pro-B-type natriuretic peptide (NT-pro BNP), B-type natriuretic peptide (BNP), and adenosine triphosphate (ATP) in the serum. Color Doppler ultrasound imaging was conducted to examine the cardiac function indicators. Hematoxylin-eosin staining and Masson staining were conducted to observe the pathological changes in the heart, and Image J was used to calculate collagen volume fraction (CVF). Transmission electron microscopy was employed to observe the ultrastructural changes of myocardial cells. Terminal-deoxynucleoitidyl transferase-mediated nick-end labeling (TUNEL) was employed to measure the apoptosis rate of myocardial cells. Western blot was employed to determine the protein levels of mitochondrial fission protein 1 (Fis1) and mitochondrial fission factor (Mff) in the outer mitochondrial membrane of the myocardial tissue.ResultCompared with the sham operation group, the model group showed elevated levels of NT-pro BNP and BNP in the serum, decreased ATP content, left ventricular ejection fraction (LVEF), and left ventricular fraction shortening (LVFS), increased left ventricular end-diastolic diameter (LVIDd) and left ventricular end-systolic diameter (LVIDs), disarrangement of myocardial cells, inflammatory cell infiltration, increased collagen fibers and CVF, damaged myocardium and mitochondria, and increased apoptosis rate of myocardial cells, and up-regulated expression of Fis1 and Mff in the cardiac tissue (P<0.01). Compared with the model group, different doses of Yixintai and trimetazidine lowered the serum levels of NT-pro BNP and BNP (P<0.05), increased the ATP content (P<0.05), increased LVEF and LVFS (P<0.01), decreased LVIDd and LVIDs (P<0.01). Moreover, the drugs alleviated the myocardial inflammatory damage and fibrosis, reduced CVF (P<0.01), repaired the myocardial mitochondrial structure, and decreased the apoptosis rate of myocardial cells (P<0.01). Medium- and high-dose Yixintai and trimetazidine down-regulated the expression of Fis1 and Mff in the myocardial tissue (P<0.05).ConclusionYixintai can improve mitochondrial structure, reduce myocardial cell apoptosis, and improve cardiac function by inhibiting the expression of Fis1 and Mff in the myocardial tissue.

      摘要:ObjectiveTo observe the clinical effect of Qingxin Zishen decoction on hot flashes after endocrine therapy for prostate cancer and explore its therapeutic mechanism.MethodA total of 60 patients who met the criteria and were admitted to Jiangsu Province Hospital of Chinese Medicine from December 2021 to December 2022 were collected and randomly divided into a treatment group and a control group, with 30 cases in each group. The treatment group was treated with Qingxin Zishen decoction, while the control group was only given routine nursing. The observation period of this study was eight weeks. The improvement of hot flash frequency, hot flash degree, hot flash score, ISS score, and TCM syndrome score were observed in the two groups before and after treatment. The changes of serum endothelin-1 (ET-1), nitric oxide (NO), calcitonin gene-related peptide (CGRP), prostate specific antigen (PSA), and testosterone were detected.ResultIn terms of efficacy, after treatment, the frequency, degree, and score of hot flashes, ISS score, and TCM syndrome score decreased in the treatment group (P<0.05). Compared with the control group, all indicators were better in the treatment group (P<0.05). In terms of laboratory indicators, after treatment, the serum NO level in the treatment group was increased. ET-1 level was decreased. The ratio of ET-1/NO was decreased, and the CGRP level was decreased (P<0.05). However, testosterone and PSA levels were not significantly changed . Compared with the control group, after treatment, the serum NO level in the treatment group was higher, and the level of ET-1 was lower. The ratio of ET-1/NO and the CGRP level were lower (P<0.05). There were no significant differences in testosterone and PSA levels between the two groups.ConclusionQingxin Zishen decoction can significantly improve hot flashes in patients with prostate cancer after endocrine therapy. The mechanism of Qingxin Zishen decoction may be to improve the vasomotor function by regulating the expression level of vasomotor factors, so as to treat hot flashes.

      摘要:ObjectiveTo investigate the preventive and therapeutic effects of Tiaogan Huaxian pills combined with entecavir on hepatic fibrosis in chronic hepatitis B with liver Qi stagnation, spleen deficiency, and blood stasis syndrome and its effect on diffusion-weighted imaging (DWI).MethodClinical data of 117 patients with liver disease who visited the Department of Hepatology at the First Affiliated Hospital of Guangxi University of Chinese Medicine from January 2021 to April 2022 were retrospectively analyzed. According to different treatment plans, they were divided into a control group (59 cases) and a treatment group (58 cases). Both groups of patients received entecavir-based etiology treatment, and the treatment group added Tiaogan Huaxian pills on the basis of basic treatment. Both groups were treated for 24 weeks. Before and after treatment, the two groups were compared in terms of alanine aminotransferase (ALT), advanced surgical technologies (AST), total bilirubin (TBil), hepatitis B virus (HBV)-DNA conversion rate, liver stiffness measurement (LSM), four items of liver fibrosis (hyaluronidase, type Ⅲ pro-collagen, type Ⅳ collagen, and laminin), the fibrosis index based on four factors (FIB-4), the aspartate aminotransferase to platelet ratio index (APRI), the apparent diffusion coefficient (ADC) value in magnetic resonance imaging (MRI), and traditional Chinese medicine symptom scores, so as to analyze the efficacy of the two groups.ResultBefore treatment, there was no significant difference in ALT, AST, TBil, LSM, four items of liver fibrosis, FIB-4, APRI, HBV-DNA conversion rate, ADC value, and traditional Chinese medicine symptom scores between the two groups. After treatment, both groups of patients showed significant reductions in ALT, AST, TBil, LSM, hyaluronidase, type Ⅲ pro-collagen, type Ⅳ collagen, laminin, FIB-4, and APRI (P<0.05) and a significant increase in ADC value (P<0.05) and HBV-DNA conversion rate (P<0.01). The traditional Chinese medicine symptom score of the treatment group decreased significantly (P<0.05). Compared with the control group after treatment, the effective rate of clinical traditional Chinese medicine in the treatment group was 91.38% (53/58), which was significantly higher than that of the control group (54.23%, 32/59) (Z=-4.325, P<0.01). In the treatment group, ALT, AST, TBil, LSM, hyaluronidase, type Ⅲ pro-collagen, type Ⅳ collagen, laminin, FIB-4, APRI, and traditional Chinese medicine symptom scores all decreased significantly (P<0.05), and the increase in ADC values was more significant (P<0.05), while the difference in HBV-DNA conversion rate was not statistically significant. There were no serious adverse reactions or events in either group.ConclusionTiaogan Huaxian pills combined with entecavir have significant clinical efficacy in the treatment of hepatic fibrosis in chronic hepatitis B, which can reduce liver inflammation activity, delay hepatic fibrosis progression, and reduce traditional Chinese medicine symptom scores. It is worthy of clinical promotion and application.

      摘要:ObjectiveMetabolomics was used to reveal the mechanism of Aconiti Lateralis Radix Praeparata(ALRP) in attenuating toxicity by processing from the aspects of amino acid metabolism, oxidative stress and energy metabolism by analyzing multiple metabolic pathways.MethodTwenty-four rats were randomly divided into control group, raw group and processed group, 8 rats in each group. The raw and processed group were given with 0.64 g·kg-1 of raw ALRP and processed ALRP respectively every day, the control group was given with an equal amount of normal saline once a day. After continuous administration for 7 days, the urine, serum and heart tissue of rats were collected. Pathological examination of the heart was carried out using hematoxylin-eosin(HE) staining, and the activities of lactate dehydrogenase(LDH) and creatine kinase-MB(CK-MB) in serum and cardiac tissues were detected by microplate assay and immunoinhibition assay. The effects of ALRP on rat heart before and after processing were compared and analyzed. Ultra performance liquid chromatography-quadrupole-time-of-flight mass spectrometry(UPLC-Q-TOF-MS) was used to perform urine metabolomics analysis, and multivariate statistical analysis was used to screen for differential metabolites related to ALRP in attenuating toxicity by processing, and pathway enrichment analysis was carried out to explore the processing mechanism.ResultHE staining showed that no obvious pathological changes were observed in the heart tissue of the control group, while obvious infiltration of inflammatory cells such as plasma cells and granulocytes was observed in the heart tissue of the raw group, indicating that the raw ALRP had strong cardiotoxicity. There was no significant difference in HE staining of heart tissue between the processed group and the control group, indicating that the toxicity of ALRP was significantly reduced after processing. Compared with the control group, the activities of LDH and CK-MB were significantly increased in serum and heart tissue of the raw group, and those were significantly decreased in serum and heart tissue of the processed group, suggesting that the myocardial toxicity of processed ALRP was reduced. A total of 108 endogenous differential metabolites associated with the raw ALRP were screened using multivariate statistical analysis in positive and negative modes, of which 51 differential metabolites were back-regulated by the processed ALRP. Biological analysis of the key regulatory pathways and associated network changes showed that the pathways related to toxicity of ALRP mainly included tryptophan metabolism, arginine and proline metabolism, phenylalanine metabolism, aminoacyl-tRNA biosynthesis, alanine, aspartate and glutamate metabolism, etc. The metabolic pathways related to the attenuation of processed ALRP mainly included aminoacyl-tRNA biosynthesis, tryptophan metabolism, phenylalanine, tyrosine and tryptophan biosynthesis, phenylalanine metabolism and caffeine metabolism.ConclusionThe processing technology of ALRP in Guilingji can significantly attenuate the cardiotoxicity of raw products, the mechanism mainly involves amino acid metabolism, oxidative stress and energy metabolism, which can provide experimental bases for the research related to the mechanism of toxicity reduction of ALRP by processing and its clinical safety applications.

      摘要:ObjectiveTo explore the scientific connotation of fried charcoal survivability of Lonicerae Japonicae Flos(LJF) by analyzing the correlation between the color change and the intrinsic components during the processing of LJF Carbonisata(LJFC), and taking pH, charcoal adsorption and microscopic characteristics as indexes.MethodLJFC samples with different degrees of processing were prepared according to the stir-frying time of 0.0, 1.5, 3.0, 4.5, 6.0, 7.5, 9.0, 10.5 min(numbered S1-S8), and the contents of gallic acid, chlorogenic acid, cryptochlorogenic acid, rutin, luteoloside, isochlorogenic acid A and isochlorogenic acid C were determined by high performance liquid chromatography(HPLC), and the L*(brightness), a*(red-greenness) and b*(yellow-blueness) of LJFC samples with different degrees of processing were determined by spectrophotometer, and the correlation analysis and principal component analysis(PCA) between the contents of seven representative components and the color of the samples were carried out by SPSS 26. 0 and SIMCA-P 14.1. Then pH, adsorption force and characteristic structure of different samples of LJFC were detected and the processing pattern of LJFC was analyzed.ResultThe results of quantitative analysis revealed that the contents of luteoloside, rutin, chlorogenic acid and isochlorogenic acid A gradually decreased, and the contents of cryptochlorogenic acid, isochlorogenic acid C and gallic acid firstly increased and then decreased. The L* and b* of the sample powders decreased, and a* showed a trend of increasing and then decreasing. The L* and b* were positively correlated with the contents of chlorogenic acid, rutin, luteoloside, isochlorogenic acid A, b* was positively correlated with the content of gallic acid, and a* was positively correlated with the contents of cryptochlorogenic acid and isochlorogenic acid C. PCA revealed that samples could be clearly divided into 3 groups, S1-S2 as one group, S3-S5 as one group, and S6-S8 as one group, with S3 having the highest score. The results of regression analysis showed that only isochlorogenic acid C could be used to predict the contents of components by colorimetric values combined with regression equations. Physicochemical analysis showed that pH of LJFC increased with the increase of degree of charcoal stir-frying, while adsorption force showed a tendency of increasing and then decreasing, with the highest adsorption force in the S5 sample, and the non-glandular hairs, calcium oxalate clusters and pollen grains had a varying degree of decreasing with the deepening of processing degree, and the microstructures of S6-S8 samples were obviously charred with pollen grains almost invisible.ConclusionThe changes in chemical composition and color characteristics of LJFC during the processing have certain correlations, combined with the changes in physicochemical properties, S5 sample is found to be the optimal processed products, which can provide a reference for the processing standardization and quality evaluation of LJFC, and enrich the scientific connotation of fried charcoal survivability of LJF.

      摘要:In western medicine, the small intestine anatomically belongs to the digestive system and is also an important immune organ of the body. The innate immune system of the small intestine consists of a tissue barrier, innate immune cells, and innate immune molecules. The dysfunction of any part can cause metabolic disorders and eventually lead to diabetes. In the pathogenesis of diabetes, traditional Chinese medicine (TCM) has the theory of ''spleen deficiency causing diabetes'', which points out that the impaired spleen function results in inadequate transformation, impaired essence spread, and turbidity by essence accumulation, which is the core pathological link of blood glucose metabolism disorder in diabetes. In terms of the relationship between the small intestine and the spleen, the theory of TCM holds that the small intestine is located in the abdomen and the abdomen is dominated by the spleen. The digestion, absorption, and endocrine functions of the small intestine are also similar to the functions of spleen in governing movement and transformation and spreading essence by virtue of spleen Qi. Therefore, the anatomical and physiological functions of the small intestine in western medicine are closely related to the spleen in TCM. At the same time, the spleen is closely related to the innate immune function of the small intestine in TCM. The spleen participates in the generation and distribution of defense Qi, and the process of defense Qi playing the external function is similar to the process of the activation of the innate immune response. The spleen is also an important organ involved in fluid metabolism, which can cooperate with the lung and kidney to timely remove turbid fluid from the body. It can also work with the stomach as the hub of Qi ascending and descending and regulate the physiological activities of "clear Yang" and "turbid Yin", so as to ensure the homeostasis of the internal environment of the body, which is the basis for maintaining the normal function of the innate immunity of the small intestine. Therefore, taking "spleen deficiency causing diabetes" as a bridge, the theory of TCM and western medicine were combined to explain the relationship between small intestinal innate immunity imbalance and the pathogenesis of diabetes from the perspective of TCM, which is helpful to understand the pathogenesis of diabetes in a deeper level and also provide a new perspective and new way for the prevention and treatment of this disease with TCM.

      摘要:ObjectiveThis study aims to understand the recognition of practitioners in traditional Chinese medicine (TCM) hospitals on hospital-based health technology assessment (HB-HTA), assessment needs, challenges, and suggestions, so as to provide references for the future work.MethodThe convenient sampling method was adopted to survey the relevant practitioners in TCM hospitals. The questionnaire included 39 questions in 4 dimensions and was distributed through the online platform Weijuanxing.ResultA total of 244 questionnaires were recovered, and the obtained data were analyzed in SPSS. The results showed that 137 practitioners were very familiar with HB-HTA and there was no significant difference in the recognition of practitioners in different occupations (F=0.251; P=0.778). The practitioners in Hong Kong, Macao, and Taiwan had lower recognition than those in other regions. In terms of the assessment needs, 127 practitioners believed that it was very necessary to carry out HB-HTA in TCM hospitals in the future. Chinese patent medicines/Chinese herbal medicine decoction pieces (5.91) and TCM appropriate technology (5.57) had higher assessment priority scores. The assessment needs were high for the effectiveness (235 practitioners) and safety (224 practitioners) of health technology. The lack of specialized organization and standardized evaluation process system and the shortage of talents were considered to be the major challenges for the future development in this field.ConclusionThe stakeholders carrying out the health technology assessment in TCM hospitals had certain awareness of HB-HTA. Most practitioners believed that it was necessary to carry out HB-HTA in TCM hospitals in the future, while the work might face challenges such as the lack of organizations and system and the shortage of talents, which requires policy support.

      摘要:IgA nephropathy is the most common primary glomerular disease in China. Its clinical manifestations are mainly proteinuria, hematuria, hypertension, edema, hyperuricemia, etc. Most patients have hidden onset. 30%-40% of patients develop into end stage renal disease 10-20 years after diagnosis and rely on dialysis or kidney transplantation to maintain their lives, which is extremely harmful. Proteinuria is a common clinical manifestation of this disease, and most patients have small-to-moderate amounts of proteinuria, while 10%-24% of patients have large amounts of proteinuria. Proteinuria is the main risk factor affecting the progression of renal function in IgA nephropathy. Podocytes are the terminal part of the glomerular filtration barrier, and various factors can affect the fusion and detachment of podocyte processes that occur after podocyte injury. They are common histological lesions in IgA nephropathy and are key factors leading to proteinuria and the continuous progression of the disease. At present, Western medicine lacks targeted treatment for podocyte injury, with limited intervention methods. Drugs such as glucocorticoids are often used for treatment, and there are many adverse reactions. Based on the physiological function of podocytes, pathological and physiological changes after injury, and histological morphology of this disease, it is believed that it is closely related to traditional Chinese medicine's "Xuanfu Theory" "Kidney Collateral Syndrome" "Collateral Disease Theory", and "Dry Blood Theory". More and more studies have shown that traditional Chinese medicine, which has the characteristics of multiple links, pathways, and targets, has a significant therapeutic effect on podocyte injury in IgA nephropathy. It can protect podocytes and reduce proteinuria and has good application and research prospects. This article systematically summarizes the mechanism and morphological changes of podocyte injury in IgA nephropathy, the understanding of podocyte injury in traditional Chinese medicine theory, and the research progress in traditional Chinese medicine treatment of podocyte injury in IgA nephropathy, so as to provide a reference for further research and application of traditional Chinese medicine intervention in podocyte injury in IgA nephropathy.

      摘要:Wilson's disease (WD) is a copper metabolism disorder caused by mutations in the ATP7B gene, with diverse phenotypes and complex pathogenesis. It is one of the few rare diseases that can achieve good clinical efficacy through standardized treatment. Since there are few systematic reviews of this disease, we summarize the pathogenesis and treatment methods of WD from traditional Chinese and western medicine by reviewing the literature related to WD. In western medicine, ATP7B gene mutation is considered as the root cause of WD, which affects copper transport and causes copper metabolism disorders. The excessive copper deposited in the body will result in oxidative stress, defects in mitochondrial function, and cell death. Western medicine treatment of WD relies mainly on drugs, and copper antagonists are the first choice in clinical practice, which are often combined with hepatoprotective and antioxidant therapy. Surgery is a common therapy for the patients with end-stage WD, and gene therapy provides an option for WD patients. According to the traditional Chinese medicine (TCM) theory, WD is rooted in constitutional deficiency and copper accumulation and triggered by dampness-heat accumulation or phlegm combined with stasis. The patient syndrome varies in different stages of the disease, and thus the treatment should be based on syndrome differentiation. The TCM treatment method of nourishing the liver and kidneys and warming the spleen and kidneys can address the root cause. The methods of clearing heat and drying dampness, resolving phlegm and dispelling stasis, and soothing liver and regulating qi movement can be adopted to treat symptoms. On the basis of syndrome differentiation, special prescriptions for the treatment of WD have been formulated, such as Gandou decoction, Gandouling, and Gandou Fumu decoction, which have been widely used in clinical practice. TCM and western medicine have their own advantages and shortcomings. The integrated Chinese and western medicine complementing with each other demonstrates great therapeutic potential. This paper summarizes the pathogenesis and treatment of WD with integrated Chinese and western medicine, aiming to provide a reference for the clinical diagnosis and treatment of this disease.

      摘要:With the change in environmental pollution and lifestyle, the incidence and mortality of cancer are increasing year by year, which is a serious threat to human life and health. Autophagy is a process in which eukaryotic cells use lysosomes to degrade cytoplasmic proteins and damaged organelles under the regulation of autophagy-related genes. It plays a dynamic inhibiting or promoting role in the occurrence and development of cancer and is involved in the regulation of tumor formation, proliferation, metastasis, and response to anticancer therapy. With the deepening of the research on the mechanism of cancer, a variety of cancer treatment methods have been established, such as chemotherapy, radiotherapy, surgery, immunotherapy, and gene therapy. Pharmacological or genetic inhibition of autophagy has been shown to enhance the lethal effect of various anticancer treatments on tumor cells, suggesting that inhibition of autophagy is an effective sensitization strategy in cancer therapy. Meanwhile, over-stimulation of autophagy may also provide a new method for the treatment of drug-resistant cancer cells with high apoptotic thresholds. As a treasure of Chinese culture, traditional Chinese medicine plays an important role in the adjuvant treatment of cancer with its advantages of multi-target, multi-pathway, and small side effects. In recent years, many positive results have been achieved in the study of natural autophagy regulatory factors of traditional Chinese medicine in cancer, and they have been widely verified in different autophagy regulatory models. This article outlines the mechanism of autophagy, summarizes the dual regulatory role of autophagy in tumor biology, and collects relevant studies published in the databases of China National Knowledge Infrastructure (CNKI) and Wanfang Data for nearly 10 years that affect the role of tumorigenesis and development by regulating autophagy. The article also collates autophagy rules of tumor cells induced by traditional Chinese medicine and its active ingredients, so as to provide a certain reference for the research on the development and application of anti-tumor drugs.

      摘要:Chronic obstructive pulmonary disease (COPD) is one of the most common chronic diseases of the respiratory system in the clinic. The disease has a long course and is difficult to cure, which seriously threatens human health. Airway mucus hypersecretion (AMH) is an independent risk factor for COPD and has a significant impact on the development and prognosis of the disease. The review finds that the abnormal proliferation of goblet cells and the excessive secretion of mucin are the direct causes of AMH. The pathogenesis of AMH may be closely related to the inhalation of heterogeneous particles, airway inflammation, the imbalance of mucin/water salt ratio, and the regulation of related signaling pathways. Traditional Chinese medicine (TCM) believes that AMH of COPD belongs to the category of lung distension with phlegm-fluid retention syndrome, and the disease is mainly treated from phlegm on the basis of lung distension. This article summarizes the relevant research in the field of TCM in recent years and finds that the single TCM that effectively intervened AMH of COPD is mainly phlegm-resolving TCM, and the main active ingredients of TCM are flavonoids, terpenoids, phenols, and alkaloids. The main TCM compounds are mainly designed to remove heat-phlegm, warmly resolve cold-phlegm, dry dampness to eliminate phlegm, invigorate Qi, promote blood circulation and dispel phlegm, and invigorate lung, spleen, and kidney. Its mechanism of action may be direct inhibition or indirect inhibition of airway epithelial goblet cell metaplasia and mucin expression by inhibiting airway inflammation, regulating aquaporins to correct the imbalance of mucin/water salt ratio, and regulating signaling pathways, so as to reduce mucus oversecretion in COPD. However, there are still some problems. For example, the research mainly focuses on TCM compounds instead of the single TCM or its effective components. The research on the mechanism of action is not thorough enough, and the research results are not interoperable. The clinical transformation rate of basic research is insufficient. This article systematically reviews the research status of AMH in the treatment of COPD with TCM and puts forward some thoughts on the existing problems, so as to provide a reference for clinical rational medication and in-depth research.

      摘要:Colorectal cancer is a common malignant tumor in the digestive system, ranking third in incidence and second in the cause of death worldwide. In recent years, the incidence of colorectal cancer is on the rise, and the age of patients with colorectal cancer tends to be younger, with a heavy cancer burden. It is of great significance to prevent the occurrence, development, recurrence, and metastasis of colorectal cancer to reduce the incidence and mortality of colorectal cancer. Patriniae Herba has the effects of clearing heat, removing toxins, eliminating carbuncle, and discharging pus and shows good therapeutic efficacy on inflammatory bowel disease, digestive tract tumors, pelvic inflammation, gynecological tumor, and so on. Patriniae Herba is often used in the clinical treatment of colorectal cancer, but its mechanism of action is not clear. Modern studies have found that Patriniae Herba contains triterpenoids, saponins, iridoids, flavonoids, and other chemical components, with antioxidant, anti-tumor, anti-bacterial, and other pharmacological effects. The main anti-tumor components of Patriniae Herba are flavonoids. The analysis of network pharmacology and the spectrum-effect relationship has suggested that quercetin, luteolin, apigenin, isoorientin, and isovitexin play a major role in inhibiting the occurrence and development of colorectal cancer. In vivo and in vitro studies have shown that flavonoids in Patriniae Herba can play an anti-tumor role in various ways, such as preventing precancerous lesions of colorectal cancer, inhibiting the growth and proliferation of cancer cells, blocking cancer cell cycle, promoting cancer cell apoptosis, and reversing drug resistance of colorectal cancer. The oral availability of flavonoids is low. The gut is the main metabolic site of flavonoids in the body, its metabolic pathway is closely related to gut microbiota. This paper reviewed the anti-tumor mechanism of flavonoids and their influence on gut microbiota to provide a reference for further research on the mechanism of Patriniae Herba against colorectal cancer and its clinical application.

      摘要:Arrhythmia is an important disease among cardiovascular diseases. Malignant arrhythmias often occur clinically and are induced by abnormal ion channels, electrical activity disorders, myocardial fibrosis, inflammation, dysfunctional mitochondrial biogenesis, mitochondrial calcium overload, out-of-balance energy metabolism, oxidative stress, sympathetic hyperactivity, and other pathological cardiac remodeling, and they are the main causes of sudden cardiac death. In traditional Chinese medicine, arrhythmias are considered to be palpitations, which are commonly caused by deficiency of Qi and Yin. It is often manifested as a deficiency of the spleen and stomach, resulting in malfunction of the Qi mechanism, followed by a particularly severe decline in cardiac function. Shengmaisan is a representative formula for nourishing Qi and Yin, consisting of Ginseng Radix et Rhizoma, Ophiopogonis Radix, and Schisandrae Chinensis Fructus. In recent years, clinical studies have shown that Shengmaisan and its additions and subtractions are commonly used in the treatment of arrhythmias. In this article, the mechanisms of the active ingredients of Shengmaisan in the electrophysiology, biochemistry, structure, autonomic nervous system, and subcellular fraction of the heart are reviewed, and the multi-target, multi-system, and integrality of Shengmaisan in the treatment of arrhythmias of Qi and Yin deficiency are described. In addition, energy metabolism disorder is tightly juxtaposed with Qi and Yin deficiency syndrome. Mitochondria, as the center of myocardial energy metabolism, play a paramount role in cardiac remodeling, indicating that Shengmaisan will be a salient part of future research to ameliorate cardiac pathologic remodeling through energy metabolism of mitochondria, so as to provide a theoretical basis for the clinical treatment of these arrhythmias.

      摘要:Ferroptosis is a new type of programmed cell death, characterized by iron overload and lipid peroxidation. Cardiovascular disease (CVD) is an ischemic or hemorrhagic disease of the heart caused by various factors, mainly including myocardial infarction, heart failure, etc. Ferroptosis is involved in the process of myocardial cell damage and plays a driving role in the progression of various CVDs. Its main mechanisms include the destruction of iron homeostasis, the production of reactive oxygen species, the disorder of the antioxidant system, mitochondrial membrane damage, endoplasmic reticulum stress, tumor suppressor gene p53, transcription factor Nrf2 pathway, etc. Myocardial injury is one of the causes of death in many patients with heart disease. Monomers or compounds of traditional Chinese medicine have shown good effects in the treatment of myocardial cell injury caused by ferroptosis, including baicalin protecting cardiac microvascular endothelial cells of myocardial ischemia-reperfusion (I/R) rats through intracellular phosphatidylinositol kinase/phosphokinase B/endothelial nitric oxide synthase (PI3K/Akt/eNOS) pathway, Aralia elata saponin inhibiting myocardial cell ferroptosis through glucocorticoid receptor/p53/solute carrier family 7 members 11 (NR3C1/p53/SLC7A11) pathway, Xinyang tablets improving oxidative stress by regulating phosphorylated serine/threonine protein kinase/stress-activated protein kinase/p53 (MLK3/JNK/p53) signaling pathway. It is of great significance to explore the mechanism of ferroptosis and the protective effect of related traditional Chinese medicine after myocardial cell injury. This article reviews the mechanism of ferroptosis and its relationship with myocardial cells, as well as traditional Chinese medicine monomers and formulas for treating CVDs through the ferroptosis pathway. The article focuses on the pathways and effects of traditional Chinese medicine treatment, so as to provide a reference for the treatment of CVDs with traditional Chinese medicine.

      摘要:Atopic dermatitis (AD) is a chronic, recurrent, inflammatory, and pruritus skin disease caused by multiple internal and external factors, ranking first in the global burden of skin diseases. Due to the adverse reactions and high costs of conventional treatments and biologics, the development of natural products has attracted much attention. The nuclear factor-κB (NF-κB) signaling pathway is a key pathway for inhibiting inflammation and modulating immunity. This paper summarizes the pharmacological effects and molecular mechanisms of natural products such as flavonoids, alkaloids, phenols, terpenoids, coumarins, glycosides, and anthraquinones via NF-κB signaling pathway, aiming to provide guidance for the development of natural products. Basic studies have shown that natural products have high safety and efficacy. Oral or topical administration of natural products can regulate the phosphatidylinositol 3-kinase (PI3K)/protein kinase B (Akt), mitogen-activated protein kinase (MAPK), nuclear factor erythroid 2-related factor 2 (Nrf2), high mobility group box 1 protein (HMGB1)/receptor for advanced glycation endproducts (RAGE), and nucleotide-binding oligomerization domain-like receptor protein 3 (NLRP3) signaling pathways to exert anti-inflammatory, anti-allergy, antioxidant activities, thus reversing the pathological changes of AD. However, it is worth noting that the clinical application of natural products is still insufficient, and more rigorous clinical trials are still needed to verify their effects. The basic experiments and clinical evidence prove that natural products may play a role in alleviating AD, which provide a basis for evaluating the functioning mechanism of natural active substances and enrich the candidates for the development of potential drugs.

      摘要:Ulcerative colitis (UC) is a chronic inflammatory bowel disease with complex etiology. The pathogenesis of this disease, due to a combination of factors, is complex and has not yet been elucidated. Among them, intestinal mucosal barrier damage is the basic pathological change of UC. As a non-destructive response of cells, autophagy regulates intestinal mucosal immunity, inflammation, oxidative stress, and bacterial homeostasis through degradation and reabsorption to actively repair damaged intestinal mucosal barrier, exerting a key role in the occurrence and development of UC. The disease is mainly treated clinically with aminosalicylic acid preparations, glucocorticoids, and immunosuppressants. Western medicine treatment of the disease has a fast onset of effect, and the short-term efficacy is definite, but the long-term application is easy to be accompanied by more adverse reactions. Moreover, some drugs are expensive, bringing great physical and mental pain and economic burden to patients. Therefore, it is urgent to explore new therapies with stable efficacy and mild adverse effects. In recent years, a large number of studies have shown that Chinese medicine can regulate autophagy of the intestinal mucosa with multiple targets and effects and repair the intestinal mucosal barrier function, thereby inhibiting the development of UC. Many experiments have shown that the active ingredient or monomers and compound formulas of Chinese medicine can improve the immunity of the intestinal mucosa, inflammation, oxidative stress, and flora by regulating the level of autophagy to maintain the normal function of the intestinal mucosal barrier to effectively intervene in UC, providing a new measure for the prevention and treatment of UC. However, there is a lack of systematic review of Chinese medicine in regulating the level of autophagy in the intestinal mucosa for the prevention and treatment of UC. Therefore, based on the current research on UC, autophagy process, and Chinese medicine treatment, this article reviewed the relationship of autophagy and its key target proteins with UC to clarify the key role of autophagy in UC production and systematically summarized Chinese medicines targeting the regulation of autophagy to treat UC in recent years to provide new ideas for the treatment and drug development of UC.

      摘要:Osteoporosis (OP) is a common bone disease affecting the quality of life and causing huge medical burden to the patients and society. The occurrence of OP is mainly caused by excessive bone resorption and insufficient bone formation, which are directly influenced by external calcium ion balance. Calcium imbalance can impair bone integrity, reduce the calcium supply to the bone, and lower the calcium content in the bone, thus triggering OP. Drugs are the main anti-OP therapy in modern medicine, which, however, may cause adverse reactions and drug dependence. Chinese medicines have good clinical effects and high safety in treating OP, being suitable for long-term use. Recent studies have shown that Chinese medicines can alleviate estrogen deficiency, regulate bone cell and calcium metabolism, which is crucial for the formation and development of OP. The transient receptor potential cation channel superfamily V members 5 and 6 (TRPV5 and TRPV6, respectively) affect bone homeostasis by mediating the transmembrane calcium ion transport in the intestine (TRPV6) and kidney (TRPV5). Therefore, TRPV5/6 is one of the key targets to understand the anti-OP mechanisms of the effective parts of Chinese medicines, which is worthy of further study. This paper summarizes the research results about the anti-OP effects of Chinese medicines in the last two decades, especially the mechanism of regulating calcium metabolism, aiming to provide new ideas for the basic research, clinical application, and drug development of OP treatment.
