Résumé
This study aimed to explore the potential mechanism of Berberis atrocarpa Schneid. anthocyanin against Alzheimer's disease(AD) based on network pharmacology, molecular docking technology, and in vitro experiments. Databases were used to screen out the potential targets of the active components of B. atrocarpa and the targets related to AD. STRING database and Cytoscape 3.9.0 were adopted to construct a protein-protein interaction(PPI) network and carry out topological analysis of the common targets. Gene Ontology(GO) and Kyoto Encyclopedia of Genes and Genomes(KEGG) enrichment analyses were performed on the target using the DAVID 6.8 database. Molecular docking was conducted to the active components and targets related to the nuclear factor kappa B(NF-κB)/Toll-like receptor 4(TLR4) pathway. Finally, lipopolysaccharide(LPS) was used to induce BV2 cells to establish the model of AD neuroinflammation for in vitro experimental validation. In this study, 426 potential targets of active components of B. atrocarpa and 329 drug-disease common targets were obtained, and 14 key targets were screened out by PPI network. A total of 623 items and 112 items were obtained by GO functional enrichment analysis and KEGG pathway enrichment analysis, respectively. Molecular docking results showed that NF-κB, NF-κB inhibitor(IκB), TLR4, and myeloid differentiation primary response 88(MyD88) had good binding abilities to the active components, and malvidin-3-O-glucoside had the strongest binding ability. Compared with the model group, the concentration of nitric oxide(NO) decreased at different doses of malvidin-3-O-glucoside without affecting the cell survival rate. Meanwhile, malvidin-3-O-glucoside down-regulated the protein expressions of NF-κB, IκB, TLR4, and MyD88. This study uses network pharmacology and experimental verification to preliminarily reveal that B. atrocarpa anthocyanin can inhibit LPS-induced neuroinflammation by regulating the NF-κB/TLR4 signaling pathway, thereby achieving the effect against AD, which provides a theoretical basis for the study of its pharmacodynamic material basis and mechanism.

Objective: To investigate the predictive factors for bronchitis obliterans in refractory Mycoplasma pneumoniae pneumonia (RMPP). Methods: A restrospective case summary was conducted 230 patients with RMPP admitted to the Department of No.2 Respiratory Medicine of Beijing Children's Hospital, Capital Medical University from January 2013 to June 2017 were recruited. Clinical data, laboratory results, imaging results and follow-up data were collected. Based on bronchoscopy and imaging findings 1 year after discharge, all patients were divided into two groups: one group had sequelae of bronchitis obliterans (sequelae group) and the other group had not bronchitis obliterans (control group), independent sample t-test and nonparametric test were used to compare the differences in clinical features between the two groups. Receiver operating characteristic (ROC) curve to explore the predictive value of Bronchitis Obliterans in RMPP. Results: Among 230 RMPP children, there were 115 males and 115 females, 95 cases had sequelae group, the age of disease onset was (7.1±2.8) years;135 cases had control group, the age of disease onset was (6.8±2.7) years. The duration of fever, C-reative protein (CRP) and lactate dehydrogenase (LDH) levels, the proportion of ≥2/3 lobe consolidation, pleural effusion and the proportion of airway mucus plug and mucosal necrosis were longer or higher in the sequelae group than those in the control group ((17±9) vs. (12±3) d, (193±59) vs. (98±42) mg/L,730 (660, 814) vs. 486 (452, 522) U/L, 89 cases (93.7%) vs. 73 cases (54.1%), 73 cases (76.8%) vs.59 cases (43.7%), 81 cases (85.3%) vs. 20 cases (14.8%), 67 cases (70.5%) vs. 9 cases (6.7%), t=5.76, 13.35, Z=-6.41, χ2=14.64, 25.04, 22.85, 102.78, all P<0.001). Multivariate Logistic regression analysis showed that the duration of fever ≥10 days (OR=1.200, 95%CI 1.014-1.419), CRP levels increased (OR=1.033, 95%CI 1.022-1.044) and LDH levels increased (OR=1.001, 95%CI 1.000-1.003) were the risk factors for sequelae of bronchitis obliterans in RMPP. ROC curve analysis showed that CRP 137 mg/L had a sensitivity of 82.1% and a specificity of 80.1%; LDH 471 U/L had a sensitivity of 62.7% and a specificity of 60.3% for predicting the development of bronchitis obliterans. Conclusions: The long duration of fever (≥10 d), CRP increase (≥137 mg/L) may be used to predict the occurrence of sequelae of bronchitis obliterans in RMPP. It is helpful for early recognition of risk children.

And to provide a reference to establish personalized diagnosis and treatment plans for TMD patients so as to prevent TMD and reduce predisposing factors. Methods: A total of 141 TMD patients, who were admitted in the Department of Oral and Maxillofacial Surgery in School and Hospital of Stomatology, Wuhan University from October 2018 to February 2021 were selected. There were 121 females and 20 males, with an average age of 30 years. A total of 90 healthy people were included as controls. A full-time psychologist conducted relevant questionnaire surveys. The questionnaires include general clinical survey forms and TMD symptom questionnaire. In addition, Axis Ⅱ assessment instruments include graded chronic pain scale, jaw functional limitation scale, oral behaviors checklist, patient health questionnaire-9 (depression), generalized anxiety disorder scale, patient health questionnaire-15 (physical symptoms), etc. The main observational indicators include: pain level, pain impact rates, overall classification of chronic pain, limited chewing function score, limited motor function score, limited communication function score, total jaw function restricted score, depression score, anxiety score, somatic symptom score and oral behavior score.The survey data were imported into SPSS 22.0 software for statistical analysis. Results: In the TMD group 60.3% (85/141) patients had various degrees of pain, 24.1% (34/141) of those with pain effect grades from 1 to 3 and 61.0% (86/141) showed chronic pain overall grades from Ⅰ to Ⅳ. The chewing function restricted score was 2.67(1.17, 4.25), motor function restricted score was 4.25(1.75, 6.12), communication function restricted score was 1.13(1.00, 2.25) and total jaw function restricted score was 2.56(1.47, 4.15) respectively. Patients with mild depression or above accounted for 59.6%(84/141), patients with mild anxiety or above accounted for 56.7%(80/141), 46.1%(65/141) patients had somatization symptoms. Statistical differences (P<0.05) were determined between TMD group and control group in various scores of jaw function, oral behavior grading, depression, anxiety, and physical symptoms. Physical symptoms had significantly statistical difference between different diagnostic classification(P<0.05). Meanwhile, among the different chronic pain levels in the TMD group, there were statistical differences in the various scales of mandibular dysfunction, depression, anxiety, and somatization. In the TMD group, other significant differences were noticed between males and females in terms of the average score of mouth opening, verbal and facial communication, the total score of mandibular dysfunction as well as physical symptoms (P<0.05). Conclusions: Compared with the healthy people, patients with TMD had more abnormal oral behaviors, different restriction of the mandibular functional activities. At the same time, depression, anxiety, and somatization were more serious. Patients with osteoarthritis and subluxation of temporomandibular joint were more likely to suffer physical symptoms. TMD patients suffering from pain had more severe mandibular dysfunction and symptoms of depression, anxiety, and somatization.

ObjectiveTo reveal the mechanism of action of Huangqi Guizhi Wuwutang in the treatment of rheumatoid arthritis by pharmacological research based on its clinical application. MethodThe collagen-induced arthritis (CIA) rat model was established by injecting bovine type Ⅱ collagen and Freund's adjuvant at the tail, and was treated with different concentrations of Huangqi Guizhi Wuwutang. The rats were randomly divided into blank group, model group, methotrexate (0.9 mg·kg-1) group, and Huangqi Guizhi Wuwutang low- and high-dose (5.13, 20.52 g·kg-1·d-1) groups, with continuous intragastric administration for 4 weeks. The degree of joint swelling, weight, degree of foot swelling and arthritis index score were determined and the pathological changes of ankle joints were detected by hematoxylin and eosin (HE) staining to observe the therapeutic effect of Huangqi Guizhi Wuwutang on rheumatoid arthritis. In addition, enzyme-linked immunosorbent assay (ELISA) and Western blot were used to measure the expression of interleukin 1β (IL-1β), interleukin 6 (IL-6), interleukin 10 (IL-10) and tumor necrosis factor-α (TNF-α) in serum and the expression of nuclear factor kappa-B (NF-κB) pathway related proteins in synovial tissue, respectively to clarify the molecular mechanism of Huangqi Guizhi Wuwutang in the treatment of rheumatoid arthritis. ResultCompared with the conditions in blank group, the body weight and IL-10 level were decreased (P<0.01), and the degree of foot swelling and arthritis index score, the levels of IL-1β, IL-6 and TNF-α, and the expression of NF-κB pathway related proteins were increased (P<0.01,) in the model group, with impaired morphology and function of the ankle joint. Additionally, compared with the model group, Huangqi Guizhi Wuwutang low- and high-dose groups had increased body weight of rats and IL-10 level (P<0.01), and reduced degree of foot swelling and arthritis index score (P<0.05, P<0.01), levels of IL-1β, IL-6 and TNF-α (P<0.01) and expression of NF-κB pathway related proteins (P<0.05, P<0.01), with improved function and morphology of the ankle joint. ConclusionHuangqi Guizhi Wuwutang can significantly alleviate joint inflammatory injury by down-regulating NF-κB pathway and reducing the inflammatory response in CIA rats.
Résumé
Through literature research and standard retrieval, Corydalis-derived medicinal materials, the origins, and related standards were summarized. Finally, 27 medicinal materials were screened out, involving 71 species(varieties). Among them, only 11 are recorded in Chinese Pharmacopoeia(2020), National Standard for Chinese Patent Drugs·Tibetan Medicine, Tibetan Medicine Standards, and other local standards, including Corydalis Bungeanae Herba and Corydalis Herba. The names and original plants of the medicinal materials are different in different standards, and the phenomena of "same medicinal material with different names" and "same name for different medicinal materials" are prominent. Most standards only include the traits, microscopic identification, and physico-chemical property identification, with unsound quality criteria. Thus, efforts should be made to strengthen the sorting of Corydalis medicinal plants, herbal textual research, and investigation of the resources and utilization. Moreover, via modern techniques, the chemical components and medicinal material basis of different original plants should be explored and sound quality standards should be established to improve the safety and quality of Corydalis-derived medicinal materials. Summarizing Corydalis medicinal plants, Corydalis-derived medicinal materials, and related standards, this study is expected to provide a reference for the standard formulation, quality evaluation, expansion of drug sources, and rational development and utilization of Corydalis resources.

This study systematically evaluated the effectiveness and safety of Dingkundan combined with conventional western medicine in the treatment of female infertility. Four Chinese databases,three English databases, and two clinical trial registration platforms were retrieved from inception to April 2021. Two researchers independently carried out literature screening,data extraction,risk assessment of bias,and grading of evidence quality. RevMan 5.4.1 was used for data analysis. A total of 216 research articles were retrieved and 21 randomized controlled trials (RCTs) were included,involving 2 172 cases. The risks of bias in the included RCTs were high. As unraveled by Meta-analysis results, Dingkundan combined with western medicine for ovulation stimulation was superior to western medicine for ovulation stimulation alone in improving pregnancy rate and progesterone level [relative risk(RR)pregnancy rate=1.67,95% confidence interval(CI)(1.44,1.93);standardized mean difference (SMD)progesterone=1.21,95% CI(0.82,1.60)]. Dingkundan combined with western medicine for improving the endometrium was superior to western medicine for improving the endometrium alone in improving the pregnancy rate [RRpregnancy rate=1.35,95% CI(1.23,1.48)]. Dingkundan combined with clomiphene was more effective than clomiphene alone in regulating endometrial thickness and reducing follicle-stimulating hormone and estradiol levels [MDendometrial thickness=3.34,95% CI(3.27,3.41), MDfollicle-stimulating hormone=-0.42,95% CI(-0.65,-0.19), MDestradiol=-4.33,95% CI (-8.18,-0.48)]. Dingkundan combined with letrozole was superior to letrozole alone in increasing the follicle-stimulating hormone level and reducing the estradiol level [MD follicle-stimulating hormone=1.14,95% CI(0.49,1.78), MDestradiol =-33.65,95% CI(-59.13,-8.17)]. The single-study results showed that Dingkundan combined with conventional western medicine had certain advantages in regulating endometrial thickness,reducing follicle-stimulating hormone,luteinizing hormone,and estradiol levels,and increasing progesterone levels. The Grading of Recommendations, Assessment, Development, and Evaluation(GRADE)system was used for the evaluation of outcome indicators. The results showed that the quality of the evidence was graded moderate or low. Based on the existing evidence,Dingkundan combined with western medicine for infertility treatment had certain advantages in increasing the pregnancy rate, improving endometrial thickness, regulating hormone levels, and reducing adverse reactions. However,affected by the quality of the included trials,the results may have limitations,and high-quality RCTs are needed for verification in the future.

ObjectiveTo investigate the effect and mechanism of Mori Folium extract on the glucose and lipid metabolism disorders in the liver of rats with type 2 diabetes mellitus (T2DM) through the phosphatidylinositol 3-kinase/protein kinase B/peroxisome proliferation-activated receptor α/carnitine palmitoyl transferase-1 (PI3K/Akt/PPARα/CPT-1) signaling pathway. MethodThe T2DM model was induced by the high-fat diet combined with the intraperitoneal injection of streptozotocin (STZ). The model rats were randomly divided into a model group, a metformin (0.2 g·kg-1) group, and a Mori Folium water extract (4.0 g·kg-1) group according to blood glucose and body weight. In the 8-week administration, fasting blood glucose was measured at the same time every week. The histomorphological and fat changes in the rat liver were observed by hematoxylin-eosin (HE) staining and oil red O staining. The levels of total cholesterol (TC), triglyceride (TG), low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C), alanine aminotransferase (ALT), and aspartate aminotransferase (AST) in the serum were measured by biochemical methods. Western blot (WB) was used to quantitatively detect the protein expression of p-PI3K,PI3K,p-Akt,Akt,PPARα,and CPT-1 in the rat liver. ResultAfter 8-week administration, the blood glucose of rats was higher in the model group than that in the control group (P<0.01), and lower in the Mori Folium water extract group than that in the model group (P<0.01). The results of HE staining showed that the liver tissue structure of the control group was complete, and the hepatocytes were arranged radially around the central vein, while the hepatocyte injury in the model group was obvious. Compared with the model group, the Mori Folium water extract group showed improved vacuolar degeneration and no lesions such as small bile duct hyperplasia. Oil red O staining showed that there was no obvious steatosis and necrosis in the hepatocytes of rats in the control group, and no lipid droplets in the hepatocytes were observed, while the model group showed increased lipid droplets. Mori Folium significantly reduced the lipid droplets in the liver. Biochemical analysis showed that the levels of TC, TG, LDL-C, AST, and ALT in the model group were significantly higher than those in control group (P<0.01). The levels of TC, TG, LDL-C, AST, and ALT in the Mori Folium water extract group were significantly lower than those in the model group (P<0.05,P<0.01). WB showed that the protein expression of p-PI3K/PI3K, p-Akt/Akt, PPARα, and CPT-1 in the model group were lower than those in the control group (P<0.01). Mori Folium water extract could increase the protein expression of p-PI3K/PI3K, p-Akt/Akt, PPARα, and CPT-1 (P<0.05 or P<0.01). ConclusionThe hypoglycemic mechanism of Mori Folium water extract may be related to the regulation of the PI3K/Akt/PPARα/CPT-1 signaling pathway.
Résumé
Objective:To study the resources and medicinal use of Tibetan medicine Codonopsis canescens,analyze its suitable habitat,and protect its wild resources,in order to provide an important reference basis for further rational development and utilization. Method:Combined investigation methods of literature textual research,visiting investigation and on-the-spot investigation were adopted. Result:In this paper,we investigated the resources and medicinal use of C. canescens in 27 cities and counties of Sichuan,Qinghai and Tibet. Compared with historical records of C. canescens,the results showed that there was no obvious change in the distribution range,and the distribution was uneven in different places. Ganzi Prefecture, Sichuan, boasts rich resources; in particular, Luhuo county has as high as 90-120 plants/100 m2, it is estimated that the reserves per unit area of root C. canescens in this area were 3 445.32 g·m-2,which totaled 1 279.18 ton(1 ton=1 000 kg). In history,the root is the main medicinal part. However, in recent years,in order to protect resources,the aboveground part is frequently used. The clinical efficacy of Tibetan medicine is mainly to tonify Qi and activate blood circulation. It can be combined with other drugs to treat rheumatism,sores,furuncle,carbuncle and other diseases. However,the plants of Codonopsis are mixed with C. canescens in each Tibetan area,and the mixed varieties are determined according to the growing varieties of the same genus in this area. Conclusion:The reserves of wild resources of C. canescens are decreasing with the increase of clinical use and market demand of Tibetan medicine. There is serious mixture of Codonopsis plants in Tibetan areas. It is suggested paying attention to resource protection,carrying out artificial planting,establishing the standard for the medicinal use of Tibetan medicine,and promote rational and sustainable utilization of resources.
Résumé
The present study systematically evaluated the efficacy and safety of Pushen capsule (PC) in the treatment of hyperlipidemia (HPL) to provide the basis for its clinical application in the future. The randomized controlled trials (RCTs) of PC in treating HPL were comprehensively retrieved from four Chinese databases and three English databases. The included RCTs were evaluated using the Cochrane risk-of-bias tool, followed by the Meta-analysis by RevMan 5.3. Twenty-four RCTs were included, with 2 634 patients involved. The patients in the experimental group were treated with PC, PC combined with conventional therapy,or PC combined with other Chinese patent medicine. The cases in the control group were treated conventionally or by other Chinese patent medicine. Meta-analysis results showed that PC alone or in combination was superior to the treatment in the control group in improving total cholesterol (TC),triglyceride (TG),high-density lipoprotein cholesterol (HDL-C),low-density lipoprotein cholesterol (LDL-C),and total response rate. Fourteen trials reported adverse reactions, including seven reporting specific results. The adverse reactions were dominated by epigastric discomfort, but the difference was not statistically significant. However, affected by the quality of the included trials,the evidence strength of the conclusion of this study is graded low. More high-quality RCTs reported in detail are needed for further confirmation.
Résumé
Codonopsis Radix, one of the bulk commodities, has been commonly used for tonification in clinical practice. Apart from the medicinal purpose, it can also be utilized as food. Among the multiple local varieties, the ones called "Luduiduoji" in Tibetan medicine cannot be neglected, which have frequently been adopted for diminishing inflammation and swelling, invigorating spleen and stomach, and tonifying Qi, etc. Considering its complex origins and frequent substitution by or confusion with other medicinal materials, this paper reviewed the Si Bu Yi Dian, Jingzhu Bencao, ministerial and local standards, modern literature on Tibetan medicine, and the results of field investigation in major Tibetan medicine hospitals and medicinal material markets of Sichuan, Qinghai and Tibet to figure out the name, original plants, medicinal parts, effects, and local varieties of Codonopsis Radix in Tibetan medicine. The results showed that the names of local varieties were diverse, many of which were transliterated into Tibetan, with "Luduiduoji" being most well-known. It was derived from 14 species in genus Codonopsis and one in Adenophora of family Campanulaceae, with Codonopsis foetens subsp. nervosa, C. thalictrifolia var. mollis, C. canescens, C. alpina, and C. pilosula being the main species. According to literature records, the roots, aerial parts, and whole plants could all be employed as medicine, but there were certain differences in their clinical applications. At present, in order to protect the medicinal resources, Tibetan medical workers mostly collect the aerial parts, which are applicable to patients with yellow water, rheumatism, Gamba disease, and leprosy. This literature review of local varieties for Codonopsis Radix and textual research on their original plants are of great significance for elevating the standard, accelerating the pharmacodynamic research, expanding the sources and promoting the rational use of Codonopsis Radix.
Résumé
This study aims to explore the efficacy of Chinese medicine injections( CMIs) for promoting blood circulation and removing blood stasis for acute cerebral infarction from the perspectives of clinical medication and mechanism of action based on two complex network analysis methods. Firstly,the current 13 kinds of CMIs for acute cerebral infarction were obtained from 2019 List of medicines for national basic medical insurance,industrial injury insurance and maternity insurance with the method of network Meta-analysis. Secondly,with the use of network pharmacology,the mechanisms of top 2 CMIs with the highest therapeutic effect for acute cerebral infarction were explored from two levels including core target and network function enrichment. The result of network Meta-analysis showed Mailuoning Injection was superior to Danhong Injection in terms of total effectiveness rate for neurological deficit score and NIHSS score. The network pharmacology results showed that Mailuoning Injection had more core targets,interaction networks,enriched biological functions and more signaling pathways than Danhong Injection for cerebral infarction. Both two CMIs can play a role in treating cerebral infarction through core targets such as TP53 and NOS3,biological processes such as fibrinolysis,nitric oxide biosynthesis,nitric oxide-mediated signal transduction,negative regulation of apoptosis in endothelial cells and apoptosis process,as well as the signaling pathways such as PI3 K-Akt signaling pathway,HIF-1 signaling pathway and cell apoptosis signaling pathways. The results of pharmacological studies explained their differences in clinical efficacy to a certain extent. A research strategy based on curative effect should be advocated in efficacy evaluation of traditional Chinese medicine,where comparative research on clinical efficacy can be conducted firstly,and then mechanism research based on outstanding effective drugs to better provide references and basis for selection of similar competitive drugs for one disease in the clinical practice.

This study evaluated the outcome indicators of the randomized controlled trials(RCTs) of traditional Chinese medicine(TCM) in the treatment of postmenopausal osteoporosis(PMOP) to provide a reference for the related research. Four Chinese databa-ses(CNKI, VIP, Wanfang and CBM) and three English databases(Cochrane Library, EMbase and PubMed) were searched syste-matically to screen RCTs of TCM in the treatment of PMOP according to the pre-set criteria, and the quality of the included trials was evaluated by the Cochrane risk-of-bias tool. A total of 29 627 articles were initially retrieved, and finally, 43 articles were included, including 34 in Chinese and 9 in English. As revealed by the results, the outcome indicators of 43 RCTs were mainly divided into six categories, with biochemical indicators accounting for 54.59%, bone mineral density(BMD) for 26.57%, quality of life for 6.28%, fracture for 1.94%, safety for 5.31%(including adverse reactions or events) and others for 5.31%. Biochemical indicators showed the maximum occurrence, followed by BMD. Many problems were found in the selection of outcome indicators of the TCM RCTs in the treatment of PMOP, such as the confusion of primary and secondary outcome indicators, the lack of endpoint criteria and vital clinical outcome indicators substituted by intermediate indicators, inconsistent evaluation standard of syndrome curative efficacy and neglected blinding in the measurement of subjective outcome indicators. The problems also included importance given to the efficacy indicators instead of the adverse outcome indicators, unnormalized indicator name, large quantitative range of the indicators, unconventional application of TCM efficacy criteria, seldom used confidence interval, relative effect indicator and absolute effect indicator.

The medicinal part of Aucklandia lappa (Asteraceae) is its dried root, which is one of the commonly used Chinese medicinal materials. Here we reviewed sesquiterpene lactones isolated from A. lappa over the past ten years in the following aspects of pharmacological activities, pharmacokinetics, toxicology, structure–activity relationship. Pharmacological activities consist of anti-cancer, anti-inflammatory activity, anti-immunity activity, anti-oxidant activity, antimicrobial activity, spasmolytic activity and so on. The extractive, showing similar pharmacokinetics parameters, may exert their various biological activities by the interaction of their α-methylene-γ-butyrolactone moiety with the thiol groups of biomacromolecules through Michael-addition. However, the poor aqueous solubility, non-selective binding as a Michael acceptor at undesired targets limited clinical translation of this class. In order to evaluate the potential effect of the extractive applied in clinical trial, the present review outlines information on pharmacological activities, pharmacokinetics, toxicology, and structure–activity relationship, as well as the future research directions of the extractive for further development and utilization of A. lappa.
Résumé
The purpose of this study was to evaluate the selection situation of outcome indexes in randomized controlled trials of traditional Chinese medicine(TCM) in the treatment of acute ischemic stroke and to provide suggestions for future research. In this study, four Chinese databases and three English databases were searched from January 2017 to June 2019. The randomized controlled trials of traditional Chinese medicine in the treatment of ischemic stroke were selected according to the pre-established selection criteria. Cochrane bias risk assessment tool was used to evaluate the quality of the included studies. A total of 20 651 related articles were searched, and 11 662 ones were left after eliminating the repetitions. Finally, 42 articles were included, including 36 articles in Chinese and 6 articles in English, 40 randomized controlled trials and 2 registration schemes of randomized controlled trials. The results showed that the outcome indexes of 42 randomized controlled trials were mainly divided into seven categories, that is clinical outcome index, blood biochemical index, mental state evaluation index, cerebral hemodynamics index, index of evaluating the degree of carotid artery stenosis, safety indicators and other indicators. The blood biochemical index was the one with highest frequency, followed by the clinical outcome index. TCM syndrome score was used as an indicator of curative outcome in 17 studies. After the analysis, it was found that there were many problems in selecting the outcome indexes for the randomized controlled trials of traditional Chinese medicine in the treatment of cerebral apoplexy. For example, the end point index and hard index were rarely selected as the main outcome indicators, and the vast majority of them were intermediate alternative indexes; recognized curative effect could not be obtained; there were too many kinds of outcome indicators and excessive heterogeneity, hindering the promotion of superior treatment measures of traditional Chinese medicine in clinical practice. Therefore, we should draw lessons from the establishment method of the international core index outcome index set, construct the core index outcome index set of traditional Chinese medicine in the treatment of ischemic stroke, and develop the outcome index set which accords with the curative effect characteristics of traditional Chinese medicine treatment mea-sures to solve the problems effectively.

The efficacy of oral Chinese patent medicine in the treatment of acute cerebral infarction was systematically evaluated by network Meta-analysis. The literature search was conducted in three English databases(Medline, EMbase and Cochrane Library) and four Chinese databases(CNKI, VIP, WanFang and SinoMed) from inception to June 2018, and the randomized controlled trials of acute cerebral infarction were screened out according to the pre-set criteria. Two reviewers independently screened out the literature by using pre-specified eligibility criteria, and assessed the quality of included studies according to the risk of bias tool of Cochrane Handbook 5.1.0. Data analysis was conducted by using Stata 13.0 and WinBUGS 1.4.3 software. Finally, 52 RCT were included, involving 11 kinds of oral Chinese patent medicines. The results of the network Meta-analysis showed that in terms of the total effective rate, the order of efficacy was as follows: Naomaitai Capsules>Xiaoshuan Changrong Capsules>Angong Niuhuang Pills>Yangxue Qingnao Granules>Compound Danshen Dripping Pills>Naoxintong Capsules>Tongxinluo Capsules>Naoxueshu Oral Liquid>Zhuyu Tongmai Capsules>Yinxingye Tablets>Compound Danshen Tablets; in terms of neurological deficit scores, the order of efficacy was: Tongxinluo Capsules>Angong Niuhuang Pills>Compound Danshen Dripping Pills>Xiaoshuan Changrong Capsules>Yangxue Qingnao Granules>Zhuyu Tongmai Capsules>Naoxintong Capsules>Naoxueshu Oral Liquid; in terms of Barthel index score, the order of efficacy was: Xiaoshuan Changrong Capsules>Naomaitai Capsules>Naoxueshu Oral Liquid>Angong Niuhuang Pills>Tongxinluo Capsules>Zhuyu Tongmai Capsules. Although different oral Chinese patent medicines can improve these outcomes, the difference in efficacy ranking was relatively large. Because of the small number and low quality of research literature, the conclusion still needs to be proved by multi-center, large-sample, and double-blind randomized trials.

To systemically evaluate the clinical efficacy and safety of oral preparation of Xiakucao with levothyroxine(LT4) on Hashimoto's thyroiditis(HT), so as to provide the evidence for its clinical application in the future. All the included studies were retrieved from four Chinese databases and three English databases from their inception to December 2019. ROB assessment tool of cochrane system and the evidence classification recommended by GRADE were used to evaluate the quality of evidences in all included studies. RevMan 5.3 was used for Meta-analysis of the outcomes. Software TSA 0.9(trail sequential analysis) was used to estimate the sample size for Meta-analysis. The results showed that 11 randomized controlled trials and totaling 1 215 patients were included. Preparation of Xiakucao combined with LT4 was adopted as intervention in experimental group, while patients in control group were treated with LT4 alone. Meta-analysis results showed that as compared with control group, the rate of total efficacy in experimental group was significant improved, including improvement of thyroid function and thyroid autoantibodies, shrinkage of thyroid gland and nodule, and improvement of clinical symptoms such as fatigue and cold intolerance(RR=1.15, 95%CI[1.09, 1.21]). The experimental group significantly decreased the serum level of thyroperoxidase antibody TPO-Ab(SMD=-0.91, 95%CI[-1.40,-0.41]), and reduced the size of left thyroid lobe(MD=-1.46, 95%CI[-1.82,-1.11]), right thyroid lobe(MD=-1.45, 95%CI[-1.96,-0.94]) and isthmus of thyroid gland(MD=-1.08, 95%CI[-1.20,-0.95]). After evaluation based on GRADEpro, the results showed that the evidence quality of all included studies was low or very low. The result of TSA showed that the cumulative sample size had reached the expected value. However, the pooled results may be affected by one study with high bias risk, with not so high effect intensity of evidences. From this review, we can see that in treatment of HT, intervention of preparation of Xiakucao combined with LT4 has advantages on improvement of clinical efficiency, decreasing serum level of TPO-Ab and shrinkage of thyroid gland. However, due to the quality of evidence, more rigorously designed and high-quality trials are needed in the future to verify the clinical efficacy and safety of preparation of Xiakucao in treating HT.

According to the theory of traditional Chinese medicine (TCM), spleen and stomach are the most important visceral system to maintain human life and health, and healthy spleen and stomach can help to nourish the primordial qi, so as to maintain sufficient vitality of the body. Therefore, invigorating the spleen plays an important role in the prevention and recovery of human diseases. In this paper, the correlation between the theory of invigorating the spleen of TCM and the function of modern health care was discussed, and the relationship between spleen invigorating and digestive tract protection, immunomodulation, anti-oxidation, relieving physical fatigue, helping to reduce fat and lose weight, improving sleep and other modern health care functions and its mechanism were systematically summarized and analyzed. The mechanism and material basis of important spleen-invigorating Chinese medicinal materials such as Astragalus membranaceus, Poria cocos, Dioscorea opposita, Euryale ferox, Atractylodes macrocephala and Polygonatum sibiricum and classic recipe of invigorating spleen such as Guipi Decoction, Sijunzi Decoction, Buzhong Yiqi Decoction and Lizhong Decoction were briefly reviewed, in order to provide some new ideas and methods for the development and utilization of spleen-invigorating medicine and food resources in TCM and the research and development of TCM health food.
