ABSTRACT

OBJECTIVE@#To investigate a Met-controlled allosteric module (AM) of neural generation as a potential therapeutic target for brain ischemia.@*METHODS@#We selected Markov clustering algorithm (MCL) to mine functional modules in the related target networks. According to the topological similarity, one functional module was predicted in the modules of baicalin (BA), jasminoidin (JA), cholic acid (CA), compared with I/R model modules. This functional module included three genes: Inppl1, Met and Dapk3 (IMD). By gene ontology enrichment analysis, biological process related to this functional module was obtained. This functional module participated in generation of neurons. Western blotting was applied to present the compound-dependent regulation of IMD. Co-immunoprecipitation was used to reveal the relationship among the three members. We used IF to determine the number of newborn neurons between compound treatment group and ischemia/reperfusion group. The expressions of vascular endothelial growth factor (VEGF) and matrix metalloproteinase 9 (MMP-9) were supposed to show the changing circumstances for neural generation under cerebral ischemia.@*RESULTS@#Significant reduction in infarction volume and pathological changes were shown in the compound treatment groups compared with the I/R model group (P<0.05). Three nodes in one novel module of IMD were found to exert diverse compound-dependent ischemic-specific excitatory regulatory activities. An anti-ischemic excitatory allosteric module (AM@*CONCLUSIONS@#AM

ABSTRACT

Although there is guidance from different regulatory agencies, there are opportunities to bring greater consistency and stronger applicability to address the practical issues of establishing and operating a data monitoring committee (DMC) for clinical studies of Chinese medicine. We names it as a Chinese Medicine Data Monitoring Committee (CMDMC). A panel composed of clinical and statistical experts shared their experience and thoughts on the important aspects of CMDMCs. Subsequently, a community standard on CMDMCs (T/CACM 1323-2019) was issued by the China Association of Chinese Medicine on September 12, 2019. This paper summarizes the key content of this standard to help the sponsors of clinical studies establish and operate CMDMCs, which will further develop the scientific integrity and quality of clinical studies.

ABSTRACT

Objective: To investigate the mechanism of quinacridine alkaloids based on the systematic of screening compounds that play antitumor effect. Methods: The virtual screening technique was used and collected 103 quinolizidine alkaloids from Leguminosae plants, and selected eight targets, which were closely related to angiogenesis. The compounds were screened by using the LibDock module in Discovery Studio 2.5 (DS 2.5) software. In addition, the small-molecule approved drugs of targets from DrugBank database have scores, the minimum score of each target's approved drugs as threshold and the original ligand scoring were set as a reference. Results: Nineteen compounds were screened out, which scores were higher than the minimum score of approved drugs as well as being in the top of 10%, and the mechanism of quinolizidine alkaloids anti-angiogenesis was preliminarily revealed. Conclusion: The results suggest that the quinolizidine alkaloids may inhibit angiogenesis to play the role of antitumor, diabetic vascular complications and so on. Compared with traditional screening, virtual screening technology saves a lot of time, energy and resources, provided a new method for the development of angiogenesis inhibitor drugs.

ABSTRACT

To study the adverse reactions' factors to Danhong injection in the real world. A multi-center, large sample and prospective hospital centralized monitoring method was adopted, and 30 888 cases of Danhong injection from 37 national 3A hospitals were collected to carry out a nested case control design study. These cases were divided into adverse reaction group and non-adverse group. Single factor logistic regression and multiple factor logistic regression were used to analyze data, and investigate the correlation between adverse reaction and gender, allergy history, methods of administration, and combined drug use. One hundred and eight cases of adverse reactions in 30 888 patients were determined, with an incidence of 0.35%. The results showed that Danhong injection combined with other medication(potassium mendoxine magnesium, thymic peptide, celecoxib, fumarate bisoprolol) with history of adverse reactions including scephalosporin allergy and proprietary Chinese medicine allergies had more adverse reactions than the control group(<0.05, estimated coefficient>0), indicating that these six factors were the risk factors for the adverse reaction of Danhong injection. The adverse reaction of Danhong injection combined with the aspirin was less than that in the control group(<0.05, estimated coefficient<0), indicating that the aspirin was a non-risk factor for the adverse reaction of Danhong injection. All the above results indicate that the adverse factors to Danhong injection include scephalosporin allergy, patent Chinese medicine allergy, Danhong injection combined with medication(potassium mendoxine magnesium, thymic peptide, celecoxib, fumarate bisoprolol), suggesting special attention shall be paid in clinical application.

ABSTRACT

According to the principle of evidence-based medicine (EBM), Chinese medical literatures based descriptive statistical analysis of common Chinese medical syndrome types were performed. By data extraction, standardization, and frequency calculation of disease names and syndrome types from 286 literatures in line with the inclusion criteria, the frequencies of diseases and syndromes were obtained to analyze common syndrome types in clinical practice, to analyze the distribution features of disease related syndromes and syndrome related diseases, to analyze the distribution of basic Chinese medical syndrome types in clinical common diseases as a whole, thus providing reference for clinical and basic researches.
