Abstract:ObjectiveTo explore the efficacy and mechanism of Qingfei Huatan Tang on chronic obstructive pulmonary disease (COPD).MethodThe rat model of COPD was established through smoke inhalation combined with lipopolysaccharide (LPS) and pulmonary compound injection. After successful modeling, the rats were randomly divided into 6 groups, namely the control group, the COPD model group, low, medium and high-dose Qingfei Huatan Tang groups and the ambroxol group. After 28 days of modeling, the drug was administered. Low, medium and high-dose Qingfei Huatan Tang (7.5, 15, 30 g·kg-1) and ambroxol (35 mg·kg-1) were administered continuously for 14 days. Immunohistochemistry and Real-time fluorescence quantitative polymerase chain reaction (Real-time PCR) were used to detect protein expression and mRNA expression of cystic fibrosis transmembrane conductance regulator (CFTR) in pulmonary fibrosis. NCI-H292 cells were induced by LPS to establish a mucus hypersecretion model. The experiment was divided into 8 groups, namely the blank control group, LPS group, LPS+10% fetal bovine serum group, LPS+ physiological serum group, LPS+5% drug serum group, LPS+10% drug serum group, LPS+20% drug serum group and LPS+AG490 group. Immunofluorescence, Western blot and Real-time PCR were used to observe the protein and mRNA expressions of CFTR in NCI-H292 cells after LPS stimulation, and western blot was used to detect the expression of tyrosine kinase 2/transcription factor 3 (JAK2/STAT3) signaling pathway in NCI-H292 cells after LPS stimulation.ResultThere were a large number of brown particles around the lumen of lung tissues in the normal group, with increased COPD expression. There were a few brown particles around the lumen of lung tissues in the model group compared with the normal group, with decreased COPD expression. Compared with the normal group, mRNA and protein expressions of CFTR in the lung tissues of the COPD model group were significantly decreased (P<0.05). Compared with the model group, mRNA and protein expressions of CFTR in the lung tissues of low, medium and high-dose Qingfei Huatan Tang groups (P<0.05). Compared with the blank control group, mRNA and protein expressions of CFTR in NCI-H292 cells of the LPS group (P<0.05), with significant increases in protein expressions of p-JAK2 and p-STAT3 (P<0.05). Compared with the model group, 5%, 10%, 20% Qingfei Huatan Tang-containing serum groups showed significant increases in mRNA and protein expressions of CFTR, but with significant decreases in p-JAK2, p-STAT3 protein expressions (P<0.05, P<0.01).ConclusionQingfei Huatan Tang up-regulated CFTR in the treatment of COPD by inhibiting JAK2/STAT3 pathway.
Abstract:Banxia Houpo Tang is widely used in modern clinics with definite curative effect. It is one of the classic famous prescriptions in the Catalogue of Ancient Classic Famous Recipes(First Batch) published by the State Administration of Traditional Chinese Medicine(TCM) in 2018. Using bibliometrics methods,collect relevant literatures of Banxia Houpo Tang in ancient medical books,analyze and verify the origin,historical evolution,composition,prescription,function,dosage,artillery,preparation method and decoction method of prescription. A total of 259 related ancient literature data were obtained,involving 107 TCM books. The inductive analysis found that Banxia Houpo Tang originated from ZHANG Zhong-jing's Synopsis of the Golden Chamberin the Han dynasty and consisted of the five flavors of Pinelliae Rhizoma,Magnoliae Officinalis Cortex,Poria,Perillae Folium and Zingiberis Rhizoma Recens. Houpo Tang,Qiqi Tang,Siqi Tang,Daqiqi Tang and other synonyms have appeared in the records of medical records of all dynasties. The prescription composition,preparation method and decoction method are used by later generations of medical practitioners. The analysis of related prescriptions is also rarely disputed. The dosage of drugs used in Banxia Houpo Tang can be calculated as 1g or 3 g. The drug processing method is different from the original one. Pinelliae Rhizoma should choose Pinelliae Rhizoma Praeparatum Cum Zingibere et Alumine and Magnoliae Officinalis Cortex as "Jianghoupu". The rest of the drug processing methods respect the 2015 edition of Chinese Pharmacopoeia. The cardiology of its treatment has also been extended and expanded. In addition to the symptoms of "burning in the pharynx" recorded by the original party,this side can also be used for heart diseases such as heartache,chest tightness,sorrow,vomiting,choking noisy and other spleen and stomach disease syndrome and spermatorrhea,turbidity,scorching and other lower coke disease syndrome.
Abstract:ObjectiveTo study the protective effect of modified Sinisan on liver injury caused by chronic unpredictable mild stress (CUMS) combined with solitary nutrition method based on a depression model.MethodForty-eight SD male rats were randomly divided into normal group, depression model group, fluoxetine group (1.58 mg·kg-1·d-1), and low, medium and high-dose modified Sinisan (3.67, 7.34, 14.68 g·kg-1·d-1) groups, with 8 rats in each group. After the administration of the model, the levels of alanine aminotransferase(ALT), aspartate aminotransferase(AST) in serum and the levels of inflammatory factors tumor necrosis factor-α(TNF-α), interleukin(IL)-1β, and IL-6 in liver tissues were measured by a biochemical kit method. Western blot was used to detect the expressions of cysteine aspastic acid-specific protease-3 (Caspase-3) and cleaved Caspase-3 in liver cells after intervention with modified Sinisan.ResultCompared with the normal group, the biochemical test showed that the levels of ALT and AST in the serum of the model group were significantly increased (P<0.05), and the levels of inflammatory factors TNF-α, IL-1β and IL-6 in liver tissue significantly increased (P<0.05). Compared with the model group, low, medium-dose modified Sinisan groups significantly reduced serum ALT, AST and inflammatory factors TNF-α, IL-1β and IL-6 levels (P<0.05). Western blot showed that compared with the normal group, the protein expression of Caspase-3 in model rat liver cells decreased, while the protein expression of cleaved Caspase-3 increased(P<0.05,P<0.01). Compared with the model group, low, medium-dose modified Sinisan groups could up-regulate Caspase-3 protein expression, and down-regulated the expression of cleaved Caspase-3 protein(P<0.05,P<0.01).ConclusionChronic stress-induced depression model can cause liver damage. Modified Sinisan can have the hepatoprotective effect by regulating the levels of various physiological, biochemical and inflammatory factor indicators, and inhibiting liver cell apoptosis.
Abstract:ObjectiveTo observe the relationship between serum homocysteine (Hcy), nitric oxide (NO), high-sensitivity C-reactive protein (hs-CRP) as well as the number and degree of coronary lesions, and the effect of Liu Junzitang combined with Erchentang on Hcy, NO, hs-CRP in patients with coronary heart disease (CHD), so as to explore the protector effect of Liu Junzitang combined with Erchentang on CHD patients.MethodA total of 76 inpatients with phlegm turbidity and internal resistance (CHD) from the Cardiovascular Department of Jiangxi University of Traditional Chinese Medicine(TCM) from November 2016 to April 2019 were selected to analyze the relationship between Hcy, NO, hs-CRP as well as the number and degree of coronary lesions. By lottery, the 76 patients were randomly divided into observation group and control group, with 38 patients in each group. Patients in the control group were given conventional therapy, while patients in the observation group were given Liu Junzitang combined with Erchentang in addition to conventional therapy. The experimental period was 3 months. TCM symptom scores of the two groups before and after administration were evaluated. Hcy, NO, hs-CRP, triglyceride (TG), low-density lipoprotein (LDL), high-density lipoprotein (HDL), and total cholesterol (TC), apolipoprotein A1 (Apo A1), apolipoprotein B (Apo B), N-terminal B-type natriuretic peptide (NT-proBNP), left ventricular ejection fraction (LVEF) indicators of the two groups were measured before and after administration.ResultThe levels of Hcy and hs-CRP were positively correlated with the number and degree of coronary lesions. The level of NO was negatively correlated with the number and degree of coronary lesions. TCM symptom scores were different between the two groups after treatment. Compared with the control group, the TCM symptom score in the observation group was decreased more significantly (P<0.05). The two groups could reduce Hcy, hs-CRP and increase in NO to a certain extent (P<0.05). Compared with the control group, the observation group showed reduction in Hcy, hs-CRP and increase in NO more significantly (P<0.05). After treatment in both groups, TG, LDL, TC, Apo A1, Apo B and HDL were reduced (P<0.05) compared with before treatment. Compared with the control group, the observation group showed decrease in TG, LDL, TC, Apo A1, Apo B and increase in HDL more significantly (P<0.05). Both groups could increase LVEF and decrease NT-proBNP after treatment (P<0.05). Compared with the control group, the observation group increased LVEF and decreased NT-proBNP more significantly (P<0.05).ConclusionThe levels of Hcy and hs-CRP were positively correlated with coronary lesions, while the level of NO was negatively correlated with coronary lesions. Modified Liu Junzitang and Erchentang may be correlated with inhibition of Hcy, hs-CRP and CHD and increase of patient's NO level, thereby reducing the patient's blood lipids, improving the patient's heart function, and improving the patient's clinical symptoms.

Abstract:ObjectiveHigh performance liquid chromatography (HPLC) fingerprints of liposoluble and water-soluble fractions of Xiaojinwan were established and the similarity of fingerprints was evaluated, so as to explore the quality consistency of Xiaojinwan.MethodChromatographic separation was carried out on Welch Ultimate AQ-C18 column (4.6 mm×250 mm, 5 μm) with the mobile phase of 0.1% phosphoric acid solution (A)-acetonitrile (B) for gradient elution (liposoluble fraction of 0-5 min, 40%B; 5-10 min, 40%-50%B; 10-20 min, 50%-60%B; 20-30 min, 60%-65%B; 30-40 min, 65%-70%B; 40-50 min, 70%-80%B; 50-60 min, 80%-90%B; 60-65 min, 90%-95%B; 65-75 min, 95%-100%B; 75-80 min, 100%B; water-soluble fraction of 0-20 min, 2%-5%B; 20-30 min, 5%-10%B; 30-37 min, 10%-20%B; 37-45 min, 20%-30%B; 45-50 min, 30%-40%B; 50-58 min, 40%B), the flow rate was 1 mL·min-1, the column temperature was 30 ℃. The detection wavelengths of the liposoluble and water-soluble fractions were 202, 250 nm, and their injection volumes were 10, 20 μL, respectively. A total of 30 batches of Xiaojinwan from five manufacturers were detected by HPLC, the chromatographic peaks of each part were analyzed by principal component analysis (PCA) and identified.ResultA total of 55 chromatographic peaks were detected in the fingerprints, and the similarity of fingerprint of 30 batches of Xiaojinwan was quite different. The relative standard deviations (RSDs) of fingerprint similarity of liposoluble and water-soluble fractions of Xiaojinwan were 21.5% and 32.8%, respectively. There were significant differences in the quality of samples from different manufacturers and the same manufacturer, and the chemical consistency evaluation results were dominated by liposoluble fraction, and the main reason for the chemical difference of this preparation was the composition of Liquidambaris Resina.ConclusionThe quality consistency of Xiaojinwan is poor. The establishment of two-fraction fingerprint provides a new idea for the overall quality evaluation and control of Xiaojinwan, and can provide a reference for the quality consistency evaluation of traditional pills.
Abstract:ObjectiveTo find the natural environmental boundary of the origin of the authentic Ligusticum chuanxiong by analyzing the distribution characteristics of soil elements in the traditional geo-authentic area and the southern continuous expanding areas along the same longitude.MethodThe contents of 24 elements both in soil and plant L. chuanxiong samples were determined by using X-ray fluorescence spectrometry (XRF) and ICP-MS,etc. Spearman correlation test was used to evaluate the correlations of rhizosphere soil and each portion of L. chuanxiong,to screen out “characteristic elements”. Bray-Curtis similarity indexes based on all elements and "characteristic elements" were used for hierarchical cluster analysis of soil samples, to identify the sample range with similar soil element charateristics to the traditional geo-authentic area of L. chuanxiong.ResultK,Mg,Mn and Rb elements were significantly correlated in rhizosphere soil and plant L. chuanxiong. Geographical differentiation of all elements and four characteristic elements showed that there was a highest similarity between geo-authentic area and its neighbor plots S1-S6 (except plot S4) in soil elements distribution, followed by plots S14-S16. The middle section plots S7-S13 in the expansion areas were quite different from the traditional geo-authentic production areas.ConclusionThe soil element characteristics in the study areas were not completely controlled by geographical distance,but demonstrated the "fault" variation in the areas along longitude. This study provides a theoretical basis for the detrrmination of suitable cultivation area for Ligusticum Chuanxiong, and the natural boundary of its geo-authentic area may be extended an additional 60 km southward along longitude beyond the traditional origin. Additionally, K,Mg,Mn and Rb characteristic elements may be the potential markers to evaluate the suitable soil environment for cultivating L. chuanxiong.
Abstract:ObjectiveBased on the hyperlipidemia rat model and network pharmacology technology, the mechanism of action of Trichosanthis Fructus-Allii Macrostemonis Bulbus herb pairs against hyperlipidemia was analyzed.MethodThe levels of blood lipids and inflammatory factors were measured through prophylactic administration of low, medium and high-dose Trichosanthis Fructus-Allii Macrostemonis Bulbus herb pairs in hyperlipidemia rats. The active ingredients of Trichosanthis Fructus-Allii Macrostemonis Bulbus herb pairs were screened out through Traditional Chinese Medicine System Pharmacology Database and Analysis Platform (TCMSP) and text mining. The targets of active ingredients screened through the Swiss Target Prediction, Similarity ensemble approach (SEA), DrugBank database. The disease targets were collected through Therapeutic Target Database (TTD), Online Mendelian Inheritance in Man (OMIM), DrugBank, DisGeNET database. The targets of active ingredients and disease target were integrated, and screened through topological parameters to gain the main candidate targets of Trichosanthis Fructus-Allii Macrostemonis Bulbus herb pairs against hyperlipidemia. The Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analysis and the gene ontology (GO) functional enrichment analysis were conducted through ClueGO and Database for Annotation, Visualization and Integrated Discovery (DAVID), respectively. The traditional Chinese medicine-chemical ingredient-target network model, and the target-pathway network model were constructed through Cytoscape, and their crosstalk target and signal pathway were analyzed.ResultAnimal experiments showed that the prophylactic administration of Trichosanthis Fructus-Allii Macrostemonis Bulbus herb pairs significantly reduced the levels of total cholesterol (TC), triglycerides (TG), low-density lipoprotein cholesterol (LDL-C) in serum of rats with hyperlipidemia, increased high-density lipoprotein (HDL-C) levels, and inhibited the expressions of interleukin-6 (IL-6) and tumor necrosis factor-α (TNF-α). According to the findings, 27 active ingredients, such as mandenol, diosmetin and α-spinasterol, might be the main active ingredients of Trichosanthis Fructus-Allii Macrostemonis Bulbus herb pairs, 16 crosstalk targets and 10 signal pathways might be the main therapeutic targets and pathways, main targeting apolipoprotein A1 (APOA1), apolipoprotein A2 (APOA2), apolipoprotein C3 (APOC3), lipoprotein lipase (LPL), low-density lipoprotein receptor (LDLR) and other crosstalk targets affected cholesterol metabolism, bile secretion, peroxisome proliferator activated receptor (PPAR) signaling pathway in regulating the lipid level, targeting tumor necrosis factor (TNF), IL-6, interleukin-1β (IL-1β), mitogen-activated protein kinase 1 (MAPK1), C-C motif chemokine 2 (CCL2) and other crosstalk targets affected tumor necrosis factor (TNF) signaling pathway, Toll-like receptor signaling pathway, interleukin-17 (IL-17) signaling pathway, and hypoxia inducible factor (HIF) signaling pathway in regulating the inflammatory factor level. The DAVID database for GO enrichment analysis showed that the hyperlipidemia was treated mainly through biological processes, such as inflammation, lipid localization, storage and lipid metabolism.ConclusionThese findings can predict the mechanism of action of Trichosanthis Fructus-Allii Macrostemonis Bulbus herb pairs against hyperlipidemia, and provide a theoretical basis for the material basis and clinical application of Trichosanthis Fructus-Allii Macrostemonis Bulbus herb pairs.

Abstract:ObjectiveTo explore the compatibility of Panlongqi tablets in the treatment of osteoarthritis.MethodNetwork pharmacology was used to predict and screen the targets and pathways related to osteoarthritis of 59 compounds in Panlongqi tablets including activating blood circulation and removing stasis group(ACRG),expelling wind-damp group(EWDG)and tonifying liver and kidney group(TLKG). Through data integration analysis, the characteristics and compatibility rules of this prescription in preventing and treating osteoarthritis were analyzed.ResultThe 59 compounds can act on 70 osteoarthritis(OA) related targets, mainly involving inflammatory stimulation response, cell proliferation, cell metabolism, immune regulation and other related processes. Pathway enrichment analysis involved inflammatory response, cartilage degeneration, immune regulation, bone metabolism and other related pathways.ConclusionThe three drugs play different regulatory roles in the pathogenesis of OA, such as inflammation, chondrocyte apoptosis and metabolism, extracellular matrix degradation, and bone metabolism. Among them, promoting blood circulation and removing blood stasis were mainly related to anti-inflammatory and analgesia, the wind-dampening group was mainly involved in regulating immunity and inflammation, and the liver-kidney group was more related to bone metabolism and chondrocyte apoptosis.
Abstract:Metabolic syndrome (MS) is a group of syndromes caused by the disorder of metabolism of various substances in the body. The main clinical manifestations are dyslipidemia, central obesity, hypertension, abnormal glucose tolerance and insulin resistance. With the changes of diet structure and habits, the incidence rate of MS is increasing, and the patients are younger. It is an important factor in many diseases, such as diabetes, atherosclerosis, coronary heart disease, hyperlipidemia, cirrhosis and some cancers. MS has seriously affected people's lives and health. Central obesity and insulin resistance are recognized as important pathogenic factors. At present, the pathogenesis of MS and its components has not been fully understood. The clinical manifestations of metabolic syndrome are complex and diverse. Traditional Chinese medicine (TCM) believes that the occurrence of metabolic syndrome is related to such factors as proper diet, emotional disorders, excessive escape and little movement, old age and physical deficiency. TCM scholars have studied the pathogenesis of MS in such pathological factors as phlegm and blood stasis, such visceral functions as liver, spleen and kidney, roles of Qi and blood, and emotional factors. As the basic substance of organism, Qi is closely related to the process of metabolism. The occurrence of MS is closely related to the rise and fall of Qi moving to and from the body as well as the abnormal gasification function of the transformation of Qi. Qi is derived from the five internal organs, which are respectively called Heart Qi, liver Qi, spleen Qi, lung Qi and kidney Qi. The "Qi of the five internal organs" is involved in the whole process of the generation, transportation and excretion of the essence of the body. Based on the "Qi of five internal organs", this paper discusses the pathogenesis of MS with phlegm, blood stasis and water drink as pathological factors.

Abstract:ObjectiveTo explore cough cases recorded in ancient traditional Chinese medicine (TCM) books based on the Rules of Latent Structure Differentiation.MethodThe 9 323 cough cases in the database of ancient TCM books and pulmonary diseases were extracted. At first, Lantern 5.0 software was used to construct the top 120 TCM hidden structure model with the frequency>100. Then, the obtained hidden variables were comprehensively clustered and interpreted.ResultThe 46 hidden variables and 114 hidden classes were obtained through the modeling of 120 traditional Chinese medicines. According to the bayesian information measure (BIC) score, the model score was -161 242.92. The model diagram was formed with Y0, Y5, Y7, Y13, Y35 and Y38 as the cores, and Y36, Y38, Y24, Y19 and Y17 involved 4 hidden classes. Ten comprehensive clustering models were summarized according to the hidden structure flow chart, among which the highest score of Z5 external cold and internal decoction syndrome was 8.4, indicating that the result of syndrome differentiation rules of Z5 had a high degree of support, and the highest mutual information degree and information coverage of Pinellia sinensis were 0.31 and 63%. Z2 had a low score for the syndrome of deficiency of lung qi and Yin, which was -2, and Schisandra had the lowest score of -15, indicating that the syndrome differentiation rules of Z2 was less supportive. Forsythia and Notopterygium both had the highest score of Z6 wind-heat attack lung syndrome and Z10 phlegm and blood-stasis pulmonary syndrome, which was 19.1, indicating that these two TCMs had a great contribution to it. According to the test, the common syndromes of cough were cold and dryness attacking the lung, kidney-Yin deficiency, kidney-Yin deficiency of the lung, cold and internal decoction, wind heat invading the lung, liver fire invading the lung, lung heat burning, phlegm-dampness blocking the lung, phlegm-stasis blocking the lung. The newly discovered cough syndromes were external cold and internal rheum syndrome and phlegm-stasis blocking the lung syndrome.ConclusionBased on the syndrome differentiation rules of hidden structure, the improved classification of cough syndromes provides ideas for the demonstration of tacit knowledge of TCM and methodological reference for the improvement of syndromes of other diseases, and is conducive to the development of valuable new prescriptions.

Abstract:The normal immune system has the ability to distinguish between "self" and "non-self". Because of its dynamic balance of "immune activity-immune tolerance", it will produce immune response to the non-self antigen, but with no response or weak response to the self-antigen. However, if the balance was broken, T cell in the abnormal immune activation state will respond continually to the self-antigen, with an abnormal immune response, which caused autoimmune disease. Pathologically, "invalid" immune recognition and immune response become the main causes for autoimmune diseases. Co-stimulatory molecule is an important link between Attach antigen presenting cells(APC) and immune cells (T cell and B cell). Studies have proved that excessive co-stimulation and/or insufficient co-inhibition could cause detect of self-tolerance and induce autoimmunity. Although co-stimulatory and co-inhibitory pathways have a significant impact on all ADS, this paper focuses on their effect on two systemic autoimmune diseases [systemic lupus erythematosus (SLE) and rheumatoid arthritis(RA)] and two organ-specific autoimmune diseases [multiple sclerosis (MS) and type 1 diabetes (T1DM)], in order to discuss the pathogenesis and relationship between co-stimulatory molecules and autoimmune diseases.
Abstract:Imperatorin, which is extracted from umbelliferous plants such as Radix Angelicae Dahuricae, Radix Saposhnikoviae and Fructus Cnidii, belongs to furanocoumarins and is especially rich in Radix Angelicae Dahuricae. Research has shown that imperatorin possesses functions of anti-inflammatory, analgesic, antibactrial, antiviral, antiallergic, anti-tumor, reverse drug resistance in tumor cells, interaction with drug metabolizing enzymes, affecting cardiovascular and nervous system effect. It is also one of the standard components in quality control of various analgesics. In recent years, research findings related to imperatorin is increasing fast. A number of patent applications have been approved for the application of imperatorin in the treatment of anti-tumor and cardiovascular diseases. In addition, since the water insolubility of imperatorin affects its bioavailability, most researchers have gradually attached importance to this aspect of research, such as modifying its structure or synthesizing its derivatives. The literatures on the pharmacological effects and mechanisms of imperatorin at home and abroad in recent years were consulted and summarized in this paper. Imperatorin was found not only to display other pharmacological effects like furanocoumarins but also could cure osteoporosis, skin diseases and show photosensitization. Moreover, the mechanism of its action has the effect of multi-pathway and multi-target, but most of the studies have not identified its targets, which still needs further study. Extensive and significant pharmacological effect make imperatorin show a great potential for development of new drugs. This paper reviews the basic properties, the progress on pharmacological effects and mechanisms of imperatorin, proposes the research status and direction of future reseach. Hopes to provide ideas for researchers and beneficial references for the future development and utilization of imperatorin.
Abstract:Aconiti Radix is a kind of medicinal material with great toxicity, which has more than 2 000 years of clinical application history, in the folk, there are often poisoning accidents caused by improper processing. The main processing purpose of Aconiti Radix in the early period was to reduce the toxicity with simple procedure and single excipient. Since the Song dynasty, with the deepening of physicians' cognition of processing and the theory of medicinal properties, the application of procedures and materials in the processing of Aconiti Radix began to become complicated, and the scope of clinical application was further expanded. In modern times, the processing technology of Aconiti Radix is mainly based on steaming and boiling, which is quite different from the traditional processing method with multiple materials and multiple processes. Based on the characteristics of many kinds of materials and processes, this paper discusses the change in processing methods of Aconiti Radix from the perspective of excipients and processes, as well as modern processing research, in order to lay a scientific foundation for exploring the effects of many kinds of materials and processes on the quality of Aconiti Radix and revealing its processing mechanism, and provide basis and reference for establishing a more reasonable and scientific processing method for Aconiti Radix in the future.
Abstract:Based on the clinical characteristics of functional dyspepsia (FD), this paper analyzes and evaluates the consistency between the existing FD animal models and the clinical standards, so as to provide ideas and references for improving the FD animal model. By listing the clinical manifestations and diagnostic criteria of dyspepsia in traditional Chinese and western medicine, this paper assessed the existing animal models of functional dyspepsia, which conformed to 11.7% of the main symptoms and 5% of the secondary symptoms in clinical diagnosis criteria in western medicine, and 15% of the main symptoms and 5% of the secondary symptoms in traditional Chinese medicine(TCM). The results showed that the high degree of anastomose was affected by "high fat feed + senna leaf decoction gavage + restraint + swimming". This method basically conformed with the clinical characteristics of FD in Chinese and western medicine. The deficiency lay in the large number of modeling factors and the lack of control, which might lead to FD model deviation. The average degree of conformity involved "gavage iodoacetamide combined with small platform station", "binding" and "tail clamping stimulation", and the low degree of conformity involved "gavage iodoacetamide" and "stomach implanted electrode". The above methods simulated the characteristics of FD, but the single factor lacked the manifestation of TCM symptoms, which needed further improvement. Therefore, multiple single factor modeling methods were combined, with focus on the development and use of TCM purgative as modeling drug, so as to control the modeling process. An attempt shall be made to develop a set of time schedule of various interference factors during the modeling period of animals, in order to constantly optimize the evaluation criteria of animal models, which is the future study direction of improving FD models.

Abstract:Occupying more than half of the tumor volume in a variety of solid tumors, tumor-associated macrophages (TAMs) are an important part of the tumor microenvironment (TME) with high plasticity and heterogeneity. In the early stages of tumor development, TAMs mediate antitumor effect through phagocytosis and their antioxidant functions. However, in order to meet the needs of self-renewal and proliferation, malignant tumor cells continuously adjust their metabolic patterns, leading to the accumulation of metabolites such as lactate, reactive oxygen species, nitric oxide, arachidonic acid and prostaglandin in the TME, which results in the changes in its inflammatory profiles, thereby altering the metabolism and function of TAMs and ultimately promoting the tumor development. Therefore, further understanding of the metabolism and immune responses of TAMs in the TME during tumor progression is warranted and the investigation may lead to identification of novel potential targets for cancer immunotherapy. This review aims to clarify the close relationship between TAMs metabolism and TME immune response, to reveal the mechanism of tumor immunosuppression produced by TAMs metabolism, and to provide new treatment ideas and approaches for tumor immunotherapy.
Abstract:Artemisia argyi is a perennial aromatic herb,which has used as a medicine for its leaves.It is spicy,bitter and warm,it has a small poison,it acts on the liver,spleen and kidney.According to traditional Chinese medicine(TCM),it has the functions of warming the bleeding,relieving cold and pain,dispelling dampness and itching,and so on.Previous researches have shown that A. argyi is used for treatment of various diseases,including pneumonia,gastritis,and hepatitis.Modern pharmacological studies have shown that it has a variety of antibacterial,antioxidant,insect-resistant,anti-inflammatory,immunomodulative and other activities,which depend on their complex chemical constituents,mainly including essential oil,flavonoids,tannins and polysaccharides.The A. argyi essential oil(AAEO)are the main active parts isolated from the extract of A. argyi,including ethers,alcohols,monoterpenes,sesquiterpenes,and other compounds,which have broad-spectrum antibacterial,antioxidant,anti-inflammatory,anti-tumor,analgesia,asthma relief and immune regulation,and have broad-spectrum biological activities.By studying the literatures at home and abroad in recent years,the chemical composition of AAEO was sorted out,and the chemical composition characteristics and contents of it prepared by different extraction methods were summarized,as well as the common chemical components detected in AAEO at the present stage.The author also reviewed a variety of pharmacological activities of AAEO,focusing on its anti-inflammatory,anti-tumor,antibacterial,antioxidant and other activities,and found that it has a good drug development prospect for inflammation,tumor,bacterial diseases and so on.In order to better exploit and utilize AAEO natural resources,the author analyzes the existing problems in the research and development process of it and puts forward that it is necessary to further and systematically explore its chemical components,pharmacological effects,basis of medicinal substances and mechanism of action,so as to lay a foundation for the comprehensive development and utilization of AAEO.
