- 摘要：Through the textual research and analysis of the variety， origin， processing， quality evaluation and clinical application of Moslae Herba in ancient and modern literature， its origin of materia medica was clarified. Moslae Herba has experienced variety changes in history. Elsholtzia ciliata was the mainstream variety during and before the Song dynasty， however， during the Ming and Qing dynasties， emerging variety of Mosla chinensis rose to the mainstream status due to its remarkable efficacy and the formation of cultivation， and differentiated into two commodities（wild variety of Qingxiangru and cultivated variety of Jiangxiangru）， cultivated products formed an authentic producing area in Jiangxi. The three varieties coexisted during the Ming and Qing dynasties， and the Elsholtzia varieties were gradually eliminated. Variety changes have caused changes in the functions and indications of drugs. E. ciliata had the effect of clearing heat and was mainly used to treat heatstroke and cholera， while M. chinensis was used for exogenous wind cold and dampness in the summer because of its warm and strong sweating properties， but not for cholera. Traditional Moslae Herba is mainly harvested in the summer and autumn （flowering to fruiting stage） and the above-ground parts are dry in the shade and used as medicine. Modern Qingxiangru is mostly harvested before the flowering period， and Jiangxiangru is harvested after flowering and fruiting in late summer and early autumn. In summary， according to the 2020 edition of Chinese Pharmacopoeia， the dried above-ground parts of Moslae Herba should be selected for Xinjia Xiangruyin in the Catalogue of Ancient Famous Classical Formulas（The First Batch）， mainly the cultivated variety of Jiangxiangru， and the raw products is cut into segments and used as medicine. It is suggested that when applying and developing famous classical formulas containing Moslae Herba at different periods of time today， the origin should be established in conjunction with clinical efficacy.关键词：famous classical formulas;Moslae Herba;Mosla chinensis;origin;geoherbalism;clinical application;quality evaluation

发布时间：2023-05-16 - 摘要：This article has systematically reviewed the name， origin， scientific name， producing area， quality evaluation， harvesting and processing methods of Polygonati Odorati Rhizoma（POR） by consulting the materia medica， medical books， prescription books and modern literature， in order to provide a reference for the development of famous classical formulas containing POR. Yuzhu was first recorded in the Shennong Bencaojing under the name of Nyuwei. After that， Weirui was used as the rectification name in the subsequent dynasties， and in recent times， the name of Yuzhu is mostly used in materia medica and prescription books. In ancient times， there were different names for Yuzhu， such as Nyuwei， Weiwei and Weirui. The names of the three are similar and there was a mixed use of the same name and foreign matter in history. In the Tang dynasty， SU Jing listed Nyuwei with the effect of curing dysentery in the intermediate of herbal part of Xinxiu Bencao according to its different efficacy. However， based on Shennong Bencaojing， Mingyi Bielu and the different energy efficiency of medical prescriptions， SU Song of the Northern Song dynasty believed that the three were medicinal materials of different origins. In short， the names of the three have been unclear in history for a long time. According to the development of the time line， this paper examines the names and realities of the three， and concludes that the two（Weiwei and Weirui） are the same medicinal material， that is， Polygonatum odoratum of Liliaceae， and the Nyuwei is Clematis apiifolia of Ranunculaceae， and the source relationship of the three is clarified. The mainstream source of Yuzhu used in the past dynasties was the rhizome of P. odoratum， which was widely distributed in the wild and has a large amount of resources. The origins of Yuzhu recorded in ancient times were mainly Taishan in Shandong， Chuzhou and Shuzhou in Anhui， and Hanzhong in Shaanxi， in modern times， it was produced in northern Hebei and Shaoyang in Hunan with high quality， and in the modern times， Jiangbei Yuzhu from Haimen in Jiangsu， Anyuzhu from Nanling， Anqing and Tongling in Anhui， Guanyuzhu from Fengrun， Yutian， Zunhua， Huailai in Hebei and Suizhong， Jinxi， Jianchang， Lingyuan， Liaoyang， Haicheng， Gaiping in Liaoning， Xiangyuzhu from Shaoyang in Hunan are the authentic medicinal material. In ancient times， the quality of Yuzhu was good if it was fat and white， while in modern times， it is better with thick roots， bright yellow color， soft texture， no stiff skin and no oiliness. In ancient times， the origin processing of POR was mostly dried in the shade， but in modern times， it is mostly sun-dried or dried after steaming and rubbing. The ancient processing was mostly scraped off the skin and soaked in honey water and then steamed through， while the modern one is mostly washed and cut into thick slices for raw use. Based on the conclusion of the herbal textual research， it is suggested that the rhizome of P. odoratum of Liliaceae be used as the source for the development of famous classical formulas， and the corresponding specifications be selected according to the processing requirements of the prescription. In view of the Yiweitang in Wenbing Tiaobian， which uses the method of frying fragrance to achieve the effect of fragrant refreshing the spleen， it can be processed by referring to the stir-frying method in the current version of Chinese Pharmacopoeia.关键词：famous classical formulas;Polygonati Odorati Rhizoma;herbal textual research;origin;scientific name;quality evaluation;processing of traditional Chinese medicine

发布时间：2023-05-16 - 摘要：Through the textual research and analysis of ancient and modern documents of Acanthopanacis Cortex（AC）， this paper combed the variety， origin， harvesting， processing and ancient quality evaluation methods of AC， and clarified the historical context of the mixing of its common counterfeit product（Periplocae Cortex）， in order to provide a basis for the development of famous classical formulas containing AC. AC was first published in Shennong Bencaojing with the name of Wujia， Wujiapi is the name rectification in all dynasties since Leigong Paozhilun. According to the description of inflorescence location and fruit morphology of Wujia in the materia medica， it is judged that the mainstream origin of AC used in previous dynasties was Acanthopanax gracilistylus. Periplocae Cortex was mixed with AC in the period of the Republic of China because it was in line with the "like Lycii Cortex， light， brittle and fragrant". The origin of Wujiapi recorded in past dynasties was concentrated in the middle and lower reaches of the Yangtze River， mainly in Hubei， Henan， Anhui and other places. Since modern times， the traditional quality evaluation of AC has been gradually summarized， with thick skin， white color and fragrant smell as the best. The traditional harvesting and processing of AC involved picking the stems in May and July of the lunar calendar， picking the roots in October， and drying in the shade. In modern times， the roots of AC are harvested， washed， peeled and dried in summer and autumn. In the past dynasties， there were rice wine processing， Euodiae Fructus boiling， ginger juice processing and other methods. In modern times， it is usually cut into thick slices after the cleansing. According to the research results， it is suggested that the root bark of A. gracilistylus should be selected as the origin of AC in famous classical formulas， which should be processed into the medicine according to the specific prescription requirements. In addition， it is suggested to restore the medicinal name of Periplocae Cortex as Yangtao， in order to reduce its chaotic influence on the medicinal use of AC.关键词：famous classical formulas;Acanthopanacis Cortex;origin plants;Periplocae Cortex;Yangtao;changes of producing area;quality evaluation

发布时间：2023-05-16 - 摘要：Danggui Buxuetang， derived from Clarifying Doubts about Damage from Internal and External Causes （Volume 2）： Treatise on Heat Injury to Stomach Qi（《内外伤辨惑论卷中·暑伤胃气论》） by LI Dongyuan in the Jin and Yuan dynasties， is a classic and famous formula for tonifying qi and generating blood that has been inherited and promoted by successive generations of medical practitioners and has been included in the "Catalogue of Ancient Classical Prescriptions （First Batch）" published by the National Administration of Traditional Chinese Medicine in 2018. The paper analyzed the historical origin， composition， dosage， processing， preparation， decocting， and taking methods， efficacy， and application of the classic formula Danggui Buxuetang by consulting ancient and modern literature and combining the key information examination principles of ancient classic prescriptions. A total of 604 pieces of information on relevant ancient literature were collected， including 186 ancient Chinese medical books， of which 40 （five in the Jin and Yuan dynasties， 19 in the Ming Dynasty， and 16 in the Qing Dynasty） had detailed records of composition， processing， and dosage. Danggui Buxuetang is mainly comprised of Astragali Radix and Angelicae Sinensis Radix. According to the ancient and modern dose conversion， there are 37.3-38.1 g of Astragali Radix and 7.5-7.6 g of Angelicae Sinensis Radix in the formula. Astragali Radix is preferably fried with honey and Angelicae Sinensis Radix with wine. Astragali Radix and Angelicae Sinensis Radix are decocted with 600 mL of water to 300 mL， and taken warm before meals. The main effect of this formula are described in ancient books as blood deficiency and fever， with symptoms of muscle fever， dryness and heat， irritability and thirst， red eyes and face， sleeplessness in daytime and night， and surging and feeble pulse which is weak under hard pressing， and it is a famous formula for replenishing qi and generating blood. Modern research shows that Danggui Buxuetang is commonly used in the treatment of various kinds of anemia， diabetic nephropathy， tumors， and cardiovascular and cerebrovascular diseases. The above research results can provide a reference for the subsequent development and research on the classic formula Danggui Buxuetang.关键词：classic prescription;Danggui Buxuetang;ancient books;textual research

发布时间：2023-05-16 - 摘要：ObjectiveTo explore the effect of Tongxie Yaofang on the immune microenvironment of colorectal cancer in mice under chronic stress and the underlying mechanism.MethodA total of 40 male SPF BABL/C mice were randomized into normal group， stress group， Tongxie Yaofang group （13.65 g·kg-1）， and Tongxie Yaofang-stress group （13.65 g·kg-1）， with 10 in each group. Chronic restraint stress was induced in mice and administration （ig） of Tongxie Yaofang began after 7 days of stress. On the 14th day， forced swim and tail suspension tests were used to examine the behavioral changes of mice after stress and the subcutaneous colorectal tumor was implanted in each group of mice. The effect of this prescription on the body mass and tumor volume of mice was observed. After the last administration， mouse serum and tumor samples were collected. The content of T lymphocytes （CD3+， CD4+， CD8+， and CD4+/CD8+） in tumor was detected by immunohistochemistry and flow cytometry and levels of corticosterone （CORT） in peripheral blood， and interleukin （IL）-2， interferon-γ （IFN-γ）， IL-6， and IL-10 in the serum were determined by enzyme-linked immunosorbent assay （ELISA）. The protein expression of inhibitor of nuclear factor-κB（IκB） kinase α/β （IKKα/β）， nuclear factor-κB （NF-κB）α （IκBα）， NF-κB p65， and phosphorylated （p）-NF-κB p65 was measured by Western blot.ResultCompared with the normal group， the stress group had large tumor volume （P<0.05）， low content of CD3+， CD4+， and CD4+/CD8+ （P<0.05， P<0.01）， high content of CD8+， low content of T helper 1 （Th1）-secreted IFN-γ （P<0.05）， high content of T helper 2 （Th2）-secreted IL-10 （P<0.05） and CORT （P<0.05）， high protein expression of p-NF-κB p65， NF-κB p65， and IKKα/β （P<0.05）， and low protein expression of IκBα （P<0.05）. Compared with the normal group， the Tongxie Yaofang group showed slow tumor growth， high content of CD3+， CD4+， and CD4+/CD8+ （P<0.01）， low content of CD8+ （P<0.05）， high content of Th1-secreted IL-2 and IFN-γ （P<0.05）， low content of Th2-secreted IL-6 and IL-10 （P<0.05）， low content of CORT， low protein expression of p-NF-κB p65， NF-κB p65， and IKKα/β （P<0.05）， and high protein expression of IκBα （P<0.01）. Tongxie Yaofang-stress group demonstrated slower tumor growth， higher content of CD3+， CD4+， and CD4+/CD8+ （P<0.01）， smaller content of CD8+ （P<0.05）， higher content of IL-2 and IFN-γ （P<0.05）， lower content of IL-6， IL-10 （P<0.05）， and CORT （P<0.05）， lower protein expression of p-NF-κB p65， NF-κB p65， and IKKα/β （P<0.05，P<0.01）， and higher protein expression of IκBα （P<0.01） than the stress group.ConclusionTongxie Yaofang can delay the growth of colorectal cancer under chronic stress and alleviate the deterioration of the immune microenvironment， possibly by inhibiting NF-κB signaling pathway， regulating the function of T lymphocyte subsets， and thus suppressing the secretion of pro-inflammatory factors.关键词：colorectal cancer;chronic stress;immune microenvironment;T lymphocyte subsets;Tongxie Yaofang;nuclear factor-κB p65 （NF-κB） signaling pathway

The AS model was induced by a high-fat diet in the mice in the experimental group for eight weeks. The model mice were then randomly divided into model group， low-， medium-， and high-dose Renshentang groups （2.715， 5.43， and 10.68 g·kg-1·d-1）， and simvastatin group （0.02 g·kg-1·d-1）. Drug treatment lasted eight weeks. Serum was taken and serum total cholesterol （CHO）， triglyceride （TG）， low-density lipoprotein cholesterol （LDL-C）， and high-density lipoprotein cholesterol （HDL-C） levels were measured by assay kits to observe the changes in lipid levels in mice. The aorta was stained with hematoxylin-eosin （HE） to observe the overall pathology of the aortic root and oil red O staining was used to detect the lipid deposition in the aortic plaque and calculate the percentage of the aortic root area to the lumen area. The protein expression of TRPV1， adenylate-activated protein kinase （AMPK）， phosphorylated AMPK （p-AMPK）， autophagy effector-1 （Beclin-1）， and microtubule-associated protein 1 light chain 3 （LC3Ⅱ） in mouse aortic tissues was determined by Western blot.ResultCompared with the normal group， the model group showed increased serum CHO， TG， and LDL-C levels， decreased HDL-C， and increased aortic root plaque area （P<0.01）. Compared with the model group， the Renshentang groups showed decreased levels of CHO， TG， and LDL-C in serum （P<0.05， P<0.01）， especially in the low- and medium-dose Renshentang groups （P<0.01）. Compared with the normal group， the simvastatin group and the Renshentang groups showed reduced aortic root plaque area （P<0.05）， especially in the high-dose Renshentang group （P<0.01）. Compared with the normal group， the model group showed decreased relative expression levels of TRPV1， p-AMPK/AMPK， Beclin-1， and LC3Ⅱ/LC3Ⅰ（P<0.05， P<0.01）. Compared with the model group， the medium- and high-dose Renshentang groups showed increased relative expression levels of TRPV1， p-AMPK/AMPK， Beclin-1， and LC3Ⅱ/LC3Ⅰ（P<0.05，P<0.01）.ConclusionThe anti-AS effect of Renshentang recorded in Synopsis of Golden Chamber may be achieved by up-regulating TRPV1 expression to restore the level of autophagy mediated by AMPK.关键词：Renshentang recorded in Synopsis of Golden Chamber;atherosclerosis （AS）;transient receptor potential vanilloid subtype 1 （TRPV1）;autophagy;apolipoprotein E knockout （ApoE-/-） mice

发布时间：2023-05-16 - 摘要：ObjectiveTo investigate the effect of Loulianwan on the gut microbiota of db/db mice with type 2 diabetes mellitus （T2DM）.MethodMale db/m+ mice aged 4-5 weeks were assigned to the normal group， and male db/db model mice of the same age were randomly divided into model group， metformin group （0.25 g·kg-1·d-1）， and Loulianwan group （13 g·kg-1·d-1）， with six mice in each group. Drug intervention lasted five weeks. The body weight， water intake， and fasting blood glucose （FBG） of the mice were recorded every week. After five weeks， the FBG， liver triglyceride （TG）， liver total cholesterol （TC）， glycated serum protein （GSP）， and fasting serum insulin （FINS） were detected， and the insulin resistance index （HOMA-IR） was calculated. The feces in the mouse intestines were collected， and the 16S rRNA sequencing technology was used to detect the structural changes in the fecal gut microbiota of mice in each group.ResultCompared with the normal group， the model group showed increased body weight， water intake， FBG， liver TG， liver TC， GSP， FINS， and HOMA-IR （P<0.01）. Compared with the model group， the Loulianwan group showed reduced water intake， FBG， liver TG， liver TC， GSP， FINS， and HOMA-IR （P<0.01）. The gut microbiota in the Loulian Lills group changed from phylum to genus level. The relative abundance of beneficial bacteria increased and the relative abundance of harmful bacteria decreased. Among them， the abundance of Akkermansia muciniphila， Blautia， Ruminococcus， and Parabacteroides increased （P<0.01）.ConclusionLoulianwan can significantly improve glucose and lipid metabolism in db/db mice with T2DM， and its mechanism may be related to the increase in the abundance of Akkermansia muciniphila， Blautia， Ruminococcus， and Parabacteroides in the intestine.关键词：Loulianwan;type 2 diabetes mellitus;glycolipid metabolism;16S rRNA sequencing technology;db/db mice

发布时间：2023-05-16 - 摘要：ObjectiveTo investigate the effects of Yanghetang （YHT） on breast cancer 4T1 cells and their mitogen-activated protein kinase （MEK）/extracellular signal-regulated kinase （ERK） signaling pathway.MethodThe YHT-containing serum was prepared from SD rats. The rats were randomly assigned into a blank group （normal saline） and low-， medium-， and high-dose （5.8， 11.6， 23.2 g·kg-1， respectively） YHT groups. The serum containing 10% YHT in each group was mixed with 90% RMPI 1640 complete medium， and the mixture was used to interfere with the cells. Cell counting kit-8 （CCK-8） method was used to detect the proliferation of the 4T1 cells treated with YHT for 24， 48， 72 h. The apoptosis， migration， and invasion of 4T1 cells were detected by flow cytometry， scratch test， and Transwell assay， respectively. Western blot was employed to determine the expression levels of MEK1/2， phosphorylation （p）-MEK1/2， ERK1/2， p-ERK1/2， and rat sarcoma virus （RAS） protein.ResultCompared with the blank group， the intervention with YHT-containing serum for 24， 48， and 72 h had significant inhibitory effect on 4T1 cell proliferation （P<0.05， P<0.01）. After intervention with YHT-containing serum for 48 h， the apoptosis rate of cells increased （P<0.01）. Compared with the blank group， the intervention with YHT for 24 h and 48 h decreased the healing ability of cells in the scratch test （P<0.01）. The invasive ability of cells treated with the low， medium， and high-dose YHT containing serum showed a decreasing trend （P<0.01）. Compared with the blank group， YHT-containing serum did not change the expression of MEK1/2 and ERK1/2 while down-regulating the expression of p-MEK1/2， p-ERK1/2， and RAS protein （P<0.01）.ConclusionYHT can inhibit the proliferation， migration， and invasion and promote the apoptosis of breast cancer 4T1 cells. In may promote the apoptosis by inhibiting the MEK/ERK signaling pathway and down-regulating the expression of p-MEK1/2， p-ERK1/2， and RAS protein.关键词：breast cancer;Yanghetang;cell proliferation;mitogen-activated protein kinase （MEK）/extracellular signal-regulated kinase （ERK） signaling pathway

发布时间：2023-05-16 - 摘要：ObjectiveTo study the mechanism of Danggui Sinitang in mitigating gouty arthritis （GA） in rats by regulating autophagy via the phosphatidylinositol 3-kinase （PI3K）/protein kinase B （Akt）/mammalian target of rapamycin （mTOR） signaling pathway.MethodSixty male SD rats were randomly assigned into normal， model， colchicine （0.3 mg·kg-1）， and low-， medium-， and high-dose Danggui Sinitang （6.54， 13.08， and 26.16 g·kg-1） groups （n=10） and administrated with corresponding drugs by gavage. The rats in the normal group and model group were administrated with equal volume of normal saline by gavage for 7 days. One hour after administration on day 5， the GA model was established by injecting sodium urate suspension （50 g·L-1） into the right ankle joint of rats in other groups except the normal group， and the rats in the normal group were injected with sterile normal saline of the same volume. The swelling and pathological changes of the ankle joint were observed. The serum levels of tumor necrosis factor-α （TNF-α）， interleukin-6 （IL-6）， and IL-1β were determined. Western blot was employed to determine the protein levels of PI3K， phosphorylated PI3K （p-PI3K）， protein kinase B （Akt）， phosphorylated Akt （p-Akt）， mTOR， phosphorylated mTOR （p-mTOR）， microtubule-associated protein 1 light chain 3 Ⅱ/Ⅰ （LC3Ⅱ/Ⅰ）， autophagy effector Beclin-1， and ubiquitin-binding protein p62 in the synovial tissue. Real-time fluorescent quantitative PCR （Real-time PCR） was employed to determine the mRNA levels of PI3K， Akt， mTOR， LC3， Beclin-1 and p62.ResultCompared with the normal control， the model group showed increased joint swelling index （P<0.01）， elevated serum levels of TNF-α， IL-6， and IL-1β， inflammatory cell infiltration， and fibrous tissue hyperplasia. In addition， the model group showed up-regulated protein levels of PI3K， p-PI3K， Akt， p-Akt， mTOR， p-mTOR， and p62 and mRNA levels of PI3K， Akt， mTOR， and p62 in the synovial tissue， while it showed down-regulated protein levels of LC3Ⅱ/Ⅰ and Beclin-1 and mRNA levels of LC3 and Beclin-1 （P<0.01）. Compared with the model group， medium- and high-dose Danggui Sinitang alleviated the joint swelling （P<0.01）， lowered the serum levels of TNF-α， IL-6， and IL-1β （P<0.05）， and relieved the inflammatory cell infiltration in the synovial tissue of the ankle joint and the fibrous tissue hyperplasia. Moreover， they down-regulated the protein levels of PI3K， p-PI3K， Akt， p-Akt， mTOR， p-mTOR， and p62 and the mRNA levels of PI3K， Akt， mTOR， and p62 in the synovial tissue （P<0.05）， while they up-regulated the protein levels of LC3Ⅱ/Ⅰ and Beclin-1 and the mRNA levels of LC3 and Beclin-1 （P<0.05）.ConclusionDanggui Sinitang， especially at a high dose， can inhibit PI3K/Akt/mTOR signaling pathway to improve autophagy in the synovial tissue， thereby mitigating GA.关键词：Danggui Sinitang;gouty arthritis;phosphatidylinositol 3-kinase （PI3K）/protein kinase B （Akt）/mammalian target of rapamycin （mTOR） signaling pathway;autophagy;synovial tissue

发布时间：2023-05-16 - 摘要：ObjectiveTo observe the anti-swelling and analgesic effects of Jianpi Tongluo prescription （JPTL） and to explore its mechanism initially.MethodA total of 120 ICR mice were divided into normal group， model group， JPTL low-， medium- and high-dose groups （5， 10， 20 g·kg-1） and positive drug （celecoxib， 0.03 g·kg-1） group， with 10 in each group （po，once a day）. Complete freund's adjuvant （CFA） was used to induce the model of chronic inflammatory pain， and xylene-induced ear swelling test， hot plate test and acetic acid writhing test were performed to observe the anti-swelling and analgesic effects of different doses of JPTL in these four acute and chronic models. Further， enzyme-linked immunosorbent assay （ELISA） was used to detect the expressions of prostaglandin E2 （PGE2）， interleukin-1β （IL-1β）， interleukin-6 （IL-6） and tumor necrosis factor-α （TNF-α） in serum and inflammatory paw of mice with chronic inflammatory pain， and the expressions of aquaporin 1 （AQP1）， aquaporin 3 （AQP3）， cyclooxygenase 1 （COX1）， cyclooxygenase 2 （COX2） and mitogen-activated protein kinases （MAPKs） in inflammatory paw were detected by Western blot， to explore the preliminary mechanism of JPTL.ResultCompared with the conditions in the normal group， there was a significant increase in the ear swelling of xylene-induced model mice， a shortened paw withdrawal latency in the hot plate test （P<0.01）. Compared with the model group， JPTL remarkably increased the inhibition rate of xylene-induced ear swelling （P<0.05， P<0.01）， prolonged the latency period of writhing caused by acetic acid and reduced the number of writhing （P<0.05， P<0.01）. Compared with normal group, the degree of feet swelling in chronic inflammatory pain mice was significantly increased， the threshold of mechanical pain was decreased and the threshold of cold pain was increased （P<0.05， P<0.01）， the protein contents of AQP1 and AQP3 in inflammatory feet were increased， and the contents of IL-1β， IL-6， TNF-α， PGE2 and COX2 in inflammatory feet were increased in serum and/or inflammatory feet. The protein expression levels of p-p38 MAPK， p-JNK and p-ERK in inflammatory feet were increased （P<0.01）. Compared with the model group， JPTL relieved paw swelling of mice with chronic inflammatory pain， elevated mechanical withdrawal threshold while decreased cold withdrawal threshold， with analgesia lasting for 4 h and the optimal time point for analgesia being 2 h after administration （P<0.05， P<0.01）. Moreover， JPTL down-regulated AQP1， AQP3， COX2， p-p38 MAPK， p-JNK and p-ERK in inflammatory paw of mice with chronic inflammatory pain and reduced IL-1β， IL-6， TNF-α， and PGE2 in serum and/or inflammatory paw， but it had no significant effect on COX1 （P<0.05， P<0.01）.ConclusionJPTL has anti-swelling and analgesic effects， and its mechanism is related to inhibiting the production of cytokines and inflammatory mediators via the down-regulation of MAPKs signaling pathway， which provides an experimental basis for the clinical application of JPTL.关键词：Jianpi Tongluo prescription;detumescence;analgesia;anti-inflammation;aquaporins;inflammatory mediator;mitogen-activated protein kinases （MAPKs）

发布时间：2023-05-16 - 摘要：ObjectiveTo observe the intervention effect of artesunate （ART） and Qingfei Paidu decoction （QFPD） on the mouse model of cytokine storm （CS） induced by viral mimic Poly （I∶C）.MethodEighty-four SPF male BALB/c mice were randomly divided into seven groups， with 12 mice in each group. Mice， except for those in the blank group （n=12）， were subjected to CS model induction by tail vein injection of Poly （I∶C） at 15 mg·kg-1， followed by drug treatments of low-dose ART （ART-l， 10 mg·kg-1）， medium-dose ART （ART-m， 20 mg·kg-1）， high-dose ART （ART-h， 40 mg·kg-1）， Qingfei Paidu Decoction （QFPD， 2.4 g·kg-1）， and dexamethasone （DXM， 10 mg·kg-1）. After 6 hours， lung tissues， bronchoalveolar lavage fluid （BALF）， spleen， lung， and peripheral blood were collected. The lung and spleen indexes were calculated and the number of inflammatory cells in BALF was detected. The pathological changes in lung tissues were observed by hematoxylin-eosin （HE） staining and the levels of tumor necrosis factor-α （TNF-α）， interferon-γ （IFN-γ）， interleukin-1β （IL-1β）， and IL-6 in BALF were detected by enzyme-linked immunosorbent assay （ELISA）. The expression of immune cells in BALF and peripheral blood was detected by flow cytometry.ResultThe analysis of lung and spleen indexes showed that compared with the blank group， the model group showed increased lung and spleen indexes to varying degrees （P<0.05）. Compared with the model group， the ART groups showed reduced spleen index （P<0.05） and the ART-l group showed reduced lung index （P<0.05）. Additionally， the QFPD group showed reduced lung and spleen indexes （P<0.05）. ELISA results showed that except for TNF-α， the levels of IFN-γ， IL-1β， and IL-6 in the model group increased compared with those in the blank group （P<0.05）. Compared with the model group， the ART-l group and the QFPD group showed reduced content of TNF-α （P<0.05）， and all groups with drug intervention showed reduced content of IFN-γ， IL-1β， and IL-6 （P<0.05）. The number of inflammatory cells in BALF showed a downward trend in the model group， and the number of cells increased in the groups with drug intervention except for the DXM group （P<0.05）. Flow cytometry showed that compared with the blank group， the model group showed decreased number of CD3 in the peripheral blood （P<0.05）， increased Ly-6G and F4/80 （P<0.05）， decreased expression of CD45， CD3， and F4/80 in BALF （P<0.05）， and increased expressions of Ly-6G （P<0.05）. Compared with the model group， the ART groups and QFPD group showed increased CD45 content in peripheral blood （P<0.05）， decreased Ly-6G and F4/80 content （P<0.05）， increased CD45 and F4/80 content in BALF （P<0.05）， and decreased expression of Ly-6G （P<0.05）.ConclusionART and QFPD have a good protective effect on Poly （I∶C）-induced CS in mice， and the mechanism is related to the effective intervention in immune cell disorder.关键词：cytokine storm;artesunate;Qingfei Paidu decoction;inflammation

The DM rat model was established by a high-fat diet combined with intraperitoneal injection of 40 mg·kg-1 STZ in other groups except the blank group. The intervention lasted for 8 weeks. The status， body weight， water intake， food intake， and fasting blood glucose （FBG） of the rats were observed and determined. Hematoxylin-eosin staining was employed to reveal the pathological changes of the pancreas， and immunohistochemistry to detect the expression of glucagon in the pancreas. Biochemical assay was employed to measure the serum levels of lipid metabolism indexes such as total cholesterol （TC）， triglyceride （TG）， low-density lipoprotein （LDL）， and high-density lipoprotein （HDL）. Enzyme-linked immunosorbent assay was employed to determine the levels of glycosylated hemoglobin， insulin， glucagon， GLP-1， and glucose-dependent insulinotropic polypeptide （GIP） in rat serum， and Western blot to determine the protein levels of GLP-1 and DPP-4 in the pancreas.ResultAfter 8 weeks of intervention， the model group showed higher body weight， FBG， TC， TG， LDL， glycosylated hemoglobin， glucagon， insulin， and insulin resistance index and lower HDL， GLP-1， and GIP than the blank group （P<0.05， P<0.01）. The Cinnamomi Cortex groups showed lower body weight， FBG， TC， TG， LDL， glycosylated hemoglobin， glucagon， insulin， and insulin resistance index and higher HDL， GLP-1， and GIP than the model group （P<0.05， P<0.01）. The Cinnamomi Cortex groups showed recovered morphology of islet cells and no nucleus aggregation. Compared with the model group， the Cinnamomi Cortex groups showed declined levels of glucagon in the center of islet cells. Compared with the blank group， the model group showed up-regulated protein level of DPP-4 and down-regulated protein level of GLP-1 （P<0.01）. Compared with the model group， the high-dose Cinnamomi Cortex groups showed down-regulated protein level of DPP-4 and up-regulated protein level of GLP-1 （P<0.05）.ConclusionCinnamomi Cortex may reduce blood glucose and improve incretin effect to lower the blood glucose level by regulating DPP-4 and GLP-1 in DM rats.关键词：diabetes mellitus;Cinnamomi Cortex;incretin effect;dipeptidyl peptidase-4 （DPP-4）;glucagon-like peptide-1 （GLP-1）;endocrine

Six ApoE-/- mice fed with common diet were used as the control group， and 6 C57BL/6J mice fed with common diet as the blank group. The drugs or equal volume of normal saline were administrated by gavage after 7 weeks of modeling， and the treatment lasted for 4 weeks. The serum levels of lipids and inflammatory cytokines ［monocyte chemoattractant protein-1 （MCP-1） and interleukin-6 （IL-6）］ were measured. Hematoxylin-eosin （HE） staining was employed to observe the pathological changes of the vascular wall of the aortic root. Immunohistochemistry was employed to detect the expression of macrophages/monocytes monoclonal antibody （MOMA-2） and α-smooth muscle actin （α-SMA）. Transmission electron microscopy was employed to count the autophagosomes in the aorta， and Western blot to determine the protein levels of Beclin-1， LC3， PI3K， Akt， and mTOR.ResultCompared with the control group， the model group showed elevated serum levels of lipids， MCP-1， and IL-6 （P<0.05）， inhibited expression of MOMA-2 and α-SMA （P<0.05， P<0.01）， up-regulated protein level of Beclin-1 （P<0.05）， and down-regulated protein levels of PI3K， Akt， and mTOR （P<0.05， P<0.01）. The model group presented obvious atherosclerotic plaques on the inner wall of the aorta， infiltration of inflammatory cells in the plaque， thickened and disarranged vascular intima where the plaque was attached， decreased autophagosomes and mitochondria， and destroyed mitochondrial structure. Chinese medicine and rapamycin groups showed lower levels of total cholesterol， triglycerides， low-density lipoprotein cholesterol， MCP-1， and IL-6 （P<0.05）， higher level of high-density lipoprotein cholesterol （P<0.05）， inhibited expression of MOMA-2 and α-SMA （P<0.05， P<0.01）， higher protein levels of Beclin-1 and LC3Ⅱ （P<0.05， P<0.01）， and lower protein levels of PI3K， Akt， and mTOR （P<0.05， P<0.01） than the model group. Moreover， Chinese medicine and rapamycin groups showed only a small number of atherosclerotic plaques on the inner wall of the aorta， reduced infiltration of inflammatory cells and thickness of the blood vessel wall， and increased autophagosomes and autophagic lysosomes.ConclusionJiedu Huoxue prescription can improve lipid metabolism， enhance macrophage autophagy， and reduce AS-induced inflammation to improve the stability of vulnerable plaques in AS mice by inhibiting the PI3K/Akt/mTOR signaling pathway.关键词：Jiedu Huoxue prescription;atherosclerosis;macrophages;autophagy;phosphatidylinositol 3-kinase （PI3K）/protein kinase B （Akt）/mammalian target of rapamycin （mTOR）

发布时间：2023-05-16 - 摘要：ObjectiveTo study the changes of mitochondrial function of ovarian granulosa cells in women of different ages and the effect of Erzhi-Tiangui prescription on in vitro fertilization-embryo transfer （IVF-ET） outcomes for elderly women， so as to verify the connotation of the "Seven-Seven" theory in the Huangdi's Internal Classic （《黄帝内经》）.MethodA total of 150 infertility patients undergoing IVF-ET at the Reproductive and Genetic Center of Integrative Medicine， Affiliated Hospital of Shandong University of Traditional Chinese Medicine were recruited and assigned into "hree-Seven/Four-Seven （30 cases）， Five-Seven （60 cases）， and Six-Seven （60 cases） groups according to the "Seven-Seven" theory. The Five-Seven and Six-Seven groups were further assigned into control and Chinese medicine subgroups using the random number plus envelope method， and the Chinese medicine group was administrated with Erzhi Tiangui prescription from the start day of controlled ovulation stimulation cycle to the trigger day. The IVF outcome was observed， and Western blot was employed to determine the levels of mitofusin 1 （MFN1）， mitofusin 2 （MFN2）， and dynamin-related protein 1 （Drp1） in the ovarian granulosa cells.ResultCompared with the Three-Seven/Four-Seven group， the control subgroups of the Five-Seven and Six-Seven groups showed decreased retrieved oocytes， two pronuclear （2PN） embryos， available embryos， high-quality embryos， clinical pregnancy rate， and live birth rate （P<0.05）. Moreover， the control subgroup of the Six-Seven group showed decreased fresh embryo transfer rate（P<0.05）. Compared with the control subgroup of the Five-Seven group， that of the Six-Seven group showed reduced retrieved oocytes， 2PN embryos， available embryos， high-quality embryos， and clinical pregnancy rate （P<0.05）. The Chinese medicine subgroup had more retrieved oocytes， 2PN oocytes， and available embryos than the control subgroup in the Five-Seven groups （P<0.05）. The Chinese medicine subgroup had more retrieved oocytes， than the control subgroup in the Six-Seven groups （P<0.05）. The control subgroup of the Six-Seven group showed lower expression levels of Mfn1 and Mfn2 and higher level of Drp1 than the control subgroup of the Five-Seven group （P<0.05）， which indicated that the levels of Mfn1 and Mfn2 in ovarian granulosa cells were down-regulated while the expression of Drp1 was up-regulated with aging （P<0.05）. The Chinese medicine subgroup had higher Mfn2 level and lower Drp1 level than the control subgroup in the Five-Seven group （P<0.05）， and the Chinese medicine subgroup had higher Mfn1 and Mfn2 levels and lower Drp1 level than then control subgroup in the Six-Seven group （P<0.05）.ConclusionsThe prognosis of IVF in women after "Five-Seven" became worse with aging， and the mitochondria in ovarian granulosa cells showed decreased fusion ability and increased fission， which verified the connotation of the "Seven-Seven" theory from the mitochondrial function. Erzhi Tiangui prescription can regulate the mitochondrial function of ovarian granulosa cells in elderly women， up-regulate the expression levels of Mfn1 and Mfn2 to promote mitochondrial fusion， and down-regulate the expression of Drp1 to reduce mitochondrial fission， thus alleviating the ovarian hypofunction caused by aging， improve the development potential of oocytes， and improve the IVF outcomes of elderly women. However， this prescription has limited efficacy for the elderly women in the age range of "Six-Seven".关键词：mitochondria;"Seven-Seven" theory;elder women;in vitro fertilization - embryo transfer;Ovarian hypofunction;kidney-tonifying herbs;Erzhi Tiangui prescription

发布时间：2023-05-16 - 摘要：ObjectiveTo screen and validate key enzyme genes affecting the polysaccharide content in different Polygonatum species and perform in-depth amino acid sequence analysis by transcriptomic analysis of P. zanlanscianense， P. kingianum， and P. cyrtonema rhizomes to enrich the transcriptome data of Polygonatum plants and provide references for polysaccharide biosynthesis mechanism and genetic improvement.MethodThe Polygonatum transcriptome was sequenced and analyzed using the Illumina NovaSeq high-throughput sequencing platform， and the differences in the transcriptomes of the three Polygonatum species were compared and according to the annotations of Nr， Gene Ontology （GO）， and Kyoto Encyclopedia of Genes and Genomes （KEGG） databases. The key enzymes in the polysaccharide metabolism pathway were screened， and the expression of key enzyme genes was clustered and correlated with the polysaccharide content. Finally， Real-time polymerase chain reaction （Real-time PCR） was performed to validate the eight key enzyme genes， and the key genes of polysaccharide biosynthesis were further screened for homologous gene sequence analysis in combination with sequencing results， followed by constructing phylogenetic trees， predicting motifs， conserved structural domains， protein sequence isoelectric points， and molecular weights， and constructing 3D protein structures by using homology modeling method.ResultThe annotation of the Nr database revealed that three Polygonatum species had the highest gene homology with Asparagus officinalis. GO database annotation results showed that three Polygonatum species differed significantly in binding， catalytic activity， metabolic processes， and cellular components， while the KEGG pathway annotation results indicated that three Polygonatum species differed significantly in the starch and sucrose metabolic pathway and galactose metabolic pathway. According to clustering analysis， correlation analysis， Real-time PCR， expression profiles， and structural and functional predictions of amino acid sequences， the key enzyme significantly affecting the polysaccharide content in different Polygonatum species was inferred to be β-fructofuranosidase （sacA）.ConclusionSacA may be the main influencing factor for the difference in polysaccharide content of Polygonatum， and is also an important reason why Polygonatum polysaccharides are mainly fructans.关键词：Polygonatum;transcriptome;polysaccharide;β-fructofuranosidase;fructosyltransferase

Quantitative analysis of the main chemical components（β-eudesmol， atractylon， atractylodin） in each volatile oil was performed by gas chromatography（GC） on the HP-5 quartz capillary column（0.32 mm×30 m， 0.25 μm） with a flame ionization detector（FID）， a split ratio of 10∶1 and a temperature program（initial temperature at 80 ℃， hold for 1 min， rise to 150 ℃ at 10 ℃·min-1， hold for 10 min， rise to 155 ℃ at 0.5 ℃·min-1， hold for 5 min， rise to 240 ℃ at 8.5 ℃·min-1， hold for 8 min）. Cluster analysis and principal component analysis（PCA） were used to explore the overall differences in types and contents of chemical components between the standard decoction concentrate and freeze-dried powder.ResultThe transfer rates of volatile oil in the bran-processed products， standard decoction concentrate and freeze-dried powder were 70.51%， 1.57% and 40.90%， respectively. The average transfer rates of β-eudesmol， atractylon and atractylodin in the volatile oil of bran-processed A. lancea were 58.45%， 48.49% and 55.64%， respectively. In the standard decoction concentrate， only β-eudesmol and atractylodin were detected， and their average transfer rates were 0.22% and 0.10%， respectively. And only β-eudesmol was detected in the freeze-dried powder with the average transfer rate of 8.37%. The results of cluster analysis and PCA showed that there are obvious differences in the types and contents of chemical components between the standard decoction concentrate and freeze-dried powder.ConclusionThe quality value transmitting between bran-processed A. lancea and its standard decoction concentrate and freeze-dried powder is stable， and if the freeze-dried powder is selected as the reference material of dispensing granules， appropriate amount of volatile oil should be added back to make it consistent with the quality of the standard decoction concentrate.关键词：bran-processed Atractylodes lancea;gas chromatography（GC）;standard decoction;freeze-dried powder;volatile oil;decoction pieces of Chinese medicine;quality value transmitting

发布时间：2023-05-16 - 摘要：ObjectiveIn the treatment of acute gouty arthritis （AGA）， western medicine is mostly used for anti-inflammatory and analgesic purposes to control the blood uric acid level， but some patients are still at risk of poor control and recurrent attacks. Chinese medicinal prescriptions， potent in resisting inflammation and relieving pain， are able to stabilize the blood uric acid level， reduce acute attacks， and improve the clinical efficacy of western medicine. However， there is a lack of evidence to support their use as evidence-based medicine. This study employed network Meta-analysis （NMA） to evaluate the efficacy and safety of common Chinese medicinal prescriptions in the treatment of AGA， aiming to provide evidence-based medical evidence for the clinical use of Chinese medicinal prescriptions in the treatment of AGA.MethodChinese and English databases were searched for prospective cohort studies and randomized controlled trials （RCTs） on Chinese medicinal prescriptions against AGA from database inception to December 1， 2022. Stata software and Review Manager were used for statistical analysis.ResultForty-four papers with 3 564 cases involved were included in the current NMA. In terms of reducing blood uric acid， the cumulative probability results showed that Mahuang Lianyao Chixiaodou Tang showed optimal efficacy （87.60%）. In terms of relieving joint pain， Danggui Niantongtang and Guizhi Shaoyao Zhimutang showed optimal efficacy （92.00% and 82.30%）. In terms of improving erythrocyte sedimentation rate （ESR）， Simiaowan was superior to other prescriptions （87.00%）. In terms of reducing C-reactive protein （CRP）， Simiaowan and Baihutang modified with Guizhitang showed superior efficacy （76.00% and 66.10%）. In terms of safety， except for the basic treatment group， Mahuang Lianyao Chixiaodou Tang had the lowest probability of adverse events， and Danggui Niantongtang had the highest probability of adverse reactions during treatment. According to the results of cluster analysis， Mahuang Lianyao Chixiaodou Tang and Simiaowan are effective and safe.ConclusionAccording to the results of NMA， Chinese medicinal prescriptions can assist in the treatment of AGA and improve the effectiveness of western medicine. For patients with AGA， clinicians can choose Mahuang Lianyao Chixiaodou Tang or Simiaowan as an auxiliary drug for routine western medicine treatment.关键词：gouty arthritis;Chinese medicinal prescriptions;Simiaowan;Mahuang Lianyao Chixiaodou Tang;network Meta-analysis

发布时间：2023-05-16 - 摘要：More and more evidence shows that there is a close relationship between the inflammatory state and coronary heart disease. Inflammatory state triggers the damage of vascular endothelium in the early stage of coronary heart disease and ultimately mediates the formation of atherosclerotic plaque. The mechanism of occurrence and development of heart disease is of great significance. Phlegm is a pathological product formed by the subtle imbalance of the spleen and stomach in the transportation and transformation of water and grain. It is the general summary of a series of abnormally accumulated inflammatory substances， such as low density lipoprotein， inflammatory cells， and inflammatory factors. The nature of Phlegm determines the invasiveness and turbidity of Phlegm. Phlegm invades the meridians， causing damage to the meridians and gradually accumulating， which eventually causes the local meridian damage to aggravate. This process is similar to the persistent damage of the vascular endothelium caused by inflammation. Phlegm blocks the meridians， affects the operation of Qi and blood， causes Qi stagnation and blood stasis， and finally forms the outcome of heart and blood stasis. This process is similar to the mechanism of atherosclerotic plaques formed by continuous inflammatory damage. Heart blood stasis， depression and heat， heat toxin endogenous， forming the syndrome of heat toxin stasis， which is similar to the process of atherosclerotic plaque rupture and thrombosis causing acute cardiovascular events.The formation of Phlegm is rooted in the deficiency of spleen. Based on the ''phlegm，stasis，toxin'' theory， spleen deficiency is the intrinsic pathogenesis of the inflammatory state of coronary heart disease， and the invasion of phlegm， blood stasis of heart， heat and blood stasis are the evolution of inflammatory damage of coronary heart disease. Traditional Chinese medicine differentiation and treatment is based on strengthening the spleen and nourishing Qi to treat the root and removing phlegm and blood stasis， and clearing heat and detoxifying to treat symptoms. The related Chinese medicine compounds， Chinese patent medicines， and single Chinese medicines can reduce the inflammatory indicators of coronary heart disease， thereby improving the prognosis of coronary heart disease.关键词：inflammation;coronary heart disease;phlegm;stasis;toxin;traditional Chinese medicine

发布时间：2023-05-16 - 摘要：Subacute thyroiditis， a common inflammatory disease of the thyroid gland， needs drug therapies due to fever， pain and other symptoms. Glucocorticoids and non-steroidal anti-inflammatory drugs （NSAIDs） are mainly used to treat this disease， while they may lead to severe side effects and high recurrence. Traditional Chinese medicine （TCM） demonstrates definite efficacy in alleviating the symptoms and shortening the disease course. The theory of excessive Qi causing fire holds that the excessive Qi of six excesses， seven emotions， or Yang hyperactivity in the Zangfu organs turns into fire and heat， resulting in pathological changes. According to this theory， this paper proposes the research on the pathogenesis and therapies of subacute thyroiditis can be started from the perspectives of Qi and fire. The disordered daily life causes internal injury of body and mind， predominant Yang Qi， or deficiency fire flaming upward， which leads to the invasion of six excesses and pathogenic toxins. Both the internal and external disorders induce the stagnation and the abnormal ascending and descending of Qi. The excessive Qi generates fire， the accumulation of which causes phlegm and stasis in front of the neck， eventually leading to the occurrence of subacute thyroiditis. The clinical and pathogenic characteristics of subacute thyroiditis indicate that the occurrence of this disease is associated with Qi and fire. Therefore， the treatment should focus on purging fire and detoxifying， regulating Qi movement， activating blood， resolving phlegm， and dissipating mass. Shengjiangsan has the effect of clearing heat and toxin， resolving phlegm， dredging collaterals， and dissipating mass， demonstrating definite therapeutic effect on subacute thyroiditis.

发布时间：2023-05-16 - 摘要：With the aging of population， osteoporosis has become one of the main diseases endangering the health of the elderly in China. Therefore， the research on osteoporosis has become a hot spot. Since Chinese medicines demonstrate significant therapeutic effects on osteoporosis， this issue is attracting increasing attention from researchers， especially in the deciphering of the molecular mechanism. This paper introduces the mechanism of the prevention and treatment of osteoporosis by Chinese medicines via the mitogen-activated protein kinase （MAPK） signaling pathway， aiming to provide a theoretical basis for deciphering the mechanism of Chinese medicines in the treatment of osteoporosis and promoting their clinical application. MAPK signaling pathway mainly involves p38 MAPK， extracellular signal-regulated kinase 1/2 （ERK1/2）， c-Jun N-terminal kinase （JNK）， and extracellular signal-regulated kinase 5 （ERK5）. Studies have shown that these proteins play a role in the progression of osteoporosis by regulating cell proliferation， differentiation， and apoptosis. Chinese medicines as a unique therapy with Chinese characteristics has definite efficacy， high safety， and mild side effects. Researchers have proved by experiments that the extracts or compounds of Chinese medicines can significantly mitigate osteoporosis by regulating the proteins involved in the MAPK signaling pathway. Therefore， this article reviews the relevant studies with focus on these proteins.关键词：osteoporosis;Chinese medicine;p38 mitogen-activated protein kinase （p38 MAPK）;extracellular signal-regulated kinase （ERK）;c-Jun N-terminal kinase （JNK）;research progress

发布时间：2023-05-16 - 摘要：Hepatocellular carcinoma （HCC） is considered to be one of the most aggressive tumors. It often occurs in patients with chronic liver disease and liver cirrhosis. Although research achievements have been attained in the current treatment methods， the opportunity of radical hepatectomy or transcatheter arterial chemoembolization has been lost due to the unobvious progression and no obvious symptoms until the late stage， which results in the poor prognosis. Tumor cells need more energy than normal cells. They maintain their growth， proliferation， and metastasis through metabolic reprogramming. Therefore， metabolic reprogramming is one of the signs of tumorigenesis. Glucose metabolism， lipid metabolism， amino acid metabolism， and nucleotide metabolism are several common cellular metabolism modes. Because the liver is the main organ of lipid metabolism， the occurrence and development of HCC is often accompanied by abnormal lipid metabolism. A variety of enzymes， proteins， genes， signaling pathways， and metabolites are involved in the lipid metabolism reprogramming of HCC. Their abnormal expression can promote lipid synthesis and lipid droplet accumulation through a variety of mechanisms， and further affect the proliferation， migration， invasion， autophagy， apoptosis， and angiogenesis of HCC cells. In recent years， traditional Chinese medicine （TCM） has demonstrated great potential in the treatment of tumors， which has attracted wide attention of scholars. The effective components in Chinese herbal medicines and Chinese medicine compound prescriptions can inhibit the de novo synthesis of lipids， lower the level of lipid accumulation， and then inhibit the occurrence and development of HCC by regulating the lipid metabolism-related enzymes， proteins， and signaling pathways. This review summarizes the mechanism of the factors regulating lipid metabolism in HCC and the research progress in the TCM inhibition of HCC by regulating lipid metabolism reprogramming， and makes an outlook on the application prospect of lipid metabolism as a new target of TCM in the treatment of HCC， aiming to provide reference for the clinical treatment of HCC.关键词：traditional Chinese medicine;hepatocellular carcinoma;lipid metabolism;mechanism

发布时间：2023-05-16 - 摘要：Inflammation， the basic pathological process of many diseases， can occur in various tissues and organs of the body and cause many diseases including cancer. So far， there are thousands of anti-inflammatory drugs on the market， but most of these drugs have adverse reactions of gastrointestinal injury， and can even cause greater damage to the body. In recent years， the research on the repurpose of Chinese medicine is in the ascendant， and the innovative research on the specific antimalarial drug artemisinin has attracted extensive attention from scholars in China and abroad. Artesunate is a water-soluble derivative of artemisinin， which has the characteristics of quick effect and low toxicity. In addition to its significant therapeutic effect on malaria， artesunate also has a potential anti-inflammatory effect. In this review， the anti-inflammatory effect and mechanism of artesunate were elaborated in detail by consulting the relevant literature. It was found that artesunate had good anti-inflammatory effects in the respiratory system， liver injury， osteoarthritis， dermatitis， kidney inflammation， colitis， neuroinflammation， and even in novel coronavirus disease 2019 （COVID-19）. It was concluded that artesunate mainly participated in apoptotic signal transduction， mediated immune regulation， and improved oxidative stress to play an anti-inflammatory role by acting on nuclear factor-κB （NF-κB）， nuclear factor E2-related factor 2 （Nrf2）， phosphatidylinositol-3 kinase （PI3K）/protein kinase B （Akt）/mammalian target of rapamycin （mTOR）， Toll-like receptor 4 （TLR4）/myeloid differentiation factor 88 （MyD88）/tumor necrosis factor receptor-associated factor 6 （TRAF6）， high mobility group box 1 （HMGB1）/receptor for advanced glycation endproduct （RAGE）， and other pathways. Through the review of the anti-inflammatory effect and mechanism of artesunate， it is expected to provide a reference for the application of artesunate in inflammation resistance and further development and utilization of artesunate in the future.关键词：artesunate;anti-inflammatory effect;mechanism;research progress

发布时间：2023-05-16 - 摘要：Traditional Chinese medicine （TCM） has certain advantages in the treatment of chronic kidney disease-mineral and bone disorder （CKD-MBD）. In recent years， there have been many studies on the treatment of CKD-MBD by Chinese medicinal compounds and monomers. As revealed by literature retrieval， the research on the mechanism of Chinese medicine in intervening in signaling pathways related to CKD-MBD was mainly based on self-made Chinese medicinal compounds， and the action pathways involved fibroblast growth factor 23/Klotho （FGF23/Klotho） signaling pathway， Wnt/β-catenin signaling pathway， receptor activator of nuclear factor-κB/receptor activator of nuclear factor-κB ligand/osteoprotegerin （RANK/RANKL/OPG） system， and other signaling pathways. TCM can improve calcium and phosphorus metabolism and bone metabolism disorder， and regulate inflammatory reaction， oxidative stress， apoptosis， and autophagy by regulating this series of signaling pathways for the treatment of CKD-MBD. This paper introduced the research results of these signaling pathways and the mechanism of TCM in the treatment of CKD-MBD in order to provide ideas and references for the related research of Chinese medicine in the treatment of CKD-MBD.关键词：chronic kidney disease-mineral and bone disorder （CKD-MBD）;vascular calcification;fibroblast growth factor 23/Klotho （FGF23/Klotho） signaling pathway;Wnt/β-catenin signaling pathway;receptor activator of nuclear factor κB/receptor activator of nuclear factor κB ligand/osteoprotegerin （RANK/RANKL/OPG） signaling pathway;traditional Chinese medicine;Chinese medicine

发布时间：2023-05-16 - 摘要：Membranous nephropathy， an autoimmune kidney disease with glomerular podocyte injury as the core mechanism， is a common pathological type of adult nephrotic syndrome and has become the main cause of end-stage renal disease in China. Podocytes are terminally differentiated cells that play an important role in maintaining the structural and functional stability of glomeruli and are molecular barriers for protein filtration. Glomerular filtration membrane injury induced by podocyte injury is an important cause of massive proteinuria. Persistent or aggravated proteinuria may prolong the course of membranous nephropathy. It is believed that podocyte destruction in membranous nephropathy is mainly related to oxidative stress， autophagy dysregulation， abnormal expression of podocyte marker proteins， chronic inflammation， epithelial-mesenchymal cell transdifferentiation， and so on. At present， western medicine mostly uses immunosuppressants and hormones for treatment according to its pathological stage， but there are certain adverse reactions. Traditional Chinese medicine （TCM） has made some achievements in the prevention and treatment of membranous nephropathy. In recent years， studies have found that many Chinese medicines can affect the occurrence and development of membranous nephropathy in different links by acting on multiple targets in the human body， with manifest advantages. This paper overviewed the podocyte injury mechanism in membranous nephropathy and summarized the treatment of membranous nephropathy with Chinese medicine monomers， compounds， and Chinese patent medicines in intervening related target pathways， aiming to provide a basis for the clinical treatment， basic research， and targeted drug development of TCM against membranous nephropathy.关键词：membranous nephropathy;podocyte;pathogenesis;traditional Chinese medicine;review

发布时间：2023-05-16 - 摘要：Diabetes retinopathy （DR） is an important cause that threatens the visual health of adults. There are some treatment methods of western medicine with definite efficacy， such as anti-vascular endothelial growth factor and laser photocoagulation， but they have many adverse reactions such as intraocular infection and visual field damage. Traditional Chinese medicine （TCM） therapies are safe and effective， which can complement western medicine. Phosphatidylinositol3-kinase （PI3K）/protein kinase B （Akt） signaling pathway regulates a range of processes including glucose metabolism， cell proliferation， and cell transcription and apoptosis， which is closely related to the occurrence and development of DR. Numerous studies have shown that TCM monomers can participate in maintaining the integrity of blood-retinal barrier and inhibiting retinal neovascularization and neurodegeneration in many aspects such as inhibiting oxidative stress and alleviating inflammatory reaction by regulating the PI3K/Akt pathway， so as to delay the progress of DR. Therefore， this study reviewed PI3K/Akt pathway and its relationship with DR， as well as the TCM monomers in interfering with DR based on PI3K/Akt pathway to provide some ideas for the prevention and treatment of DR in integrated TCM and western medicine.关键词：diabetic retinopathy;phosphatidylinositol-3-kinase （PI3K）/protein kinase B （Akt） signaling pathway;traditional Chinese medicine （TCM） monomers;blood-retinal barrier;neovascularization;neurodegeneration;research progress

发布时间：2023-05-16 - 摘要：Malignant tumors seriously threaten human life and health. Radiotherapy and chemotherapy are the conventional methods for the clinical treatment of advanced tumors. The prognosis and efficacy are still far from satisfactory due to the radiotherapy has serious adverse effects on the body and the chemotherapy often causes problems such as tumor resistance and cell proliferationinhibition. Therefore， the search for new， safe， and effective anti-tumor drugs and the elucidation of their molecular mechanisms are effective measures for clinical treatment of tumors and improvement of patients' quality of life. Active ingredients derived from Chinese herbal medicines and natural products have gradually become a hot spot in the research and development of anti-tumor drugs due to their multi-target and multi-channel anti-tumor pharmacological activity characteristics and their advantages such as less adverse reaction on the body. Bruceine D is a class of tetracyclic triterpenoids extracted from the fruit of the Chinese herbal medicine Bruceae Fructus， with anti-inflammatory， anti-malarial， anti-parasitic， and other pharmacological activities， and its anti-tumor activity is particularly significant. Pharmacological studies have found that bruceine D can regulate various cellular physiological activities such as proliferation， apoptosis， invasion， and migration of lung cancer， liver cancer， pancreatic cancer， intestinal cancer， and other cancer cells by targeting different signaling pathways. Bruceine D can be used in combination with other chemotherapeutic drugs to improve the sensitivity of tumor cells to chemotherapeutic drugs， thereby reducing the adverse effect of chemotherapy. Clinical application practice has shown that Bruceae Fructus oil emulsion injection containing bruceine D has significant advantages in the efficacy and safety of tumor treatment. Although there are many studies on the antitumor pharmacological activity of bruceine D and its clinical efficacy is significant， the specific antitumor molecular mechanism of bruceine D is still unclear， and there is a lack of systematic review on the existing antitumor mechanism of bruceine D. Therefore， based on the research on bruceine D in China and abroad in recent years， this paper reviewed the anti-tumor effect and related molecular mechanisms of bruceine D from six aspects， namely， tumor cell proliferation， apoptosis， metastasis and invasion， glucose metabolism process， autophagy， and chemotherapy sensitivity. This paper is expected to provide a pharmacological basis and scientific reference for the antitumor drug development and clinical application of bruceine D.关键词：bruceine D;anti-tumor;mechanism;research progress;signaling pathway
