Research Progress in the Application of Network Pharmacology in Traditional Chinese Medicine and Compound Prescriptions

Network pharmacology is a new discipline based on the theory of systems biology,mainly for network analysis of biological systems.It selects specific signal nodes for multi-target drug molecular design.This article summarizes the application of network pharmacology in traditional Chinese medicine and compound prescriptions in recent years from the research progress of network pharmacology,the current research status of single herbs,and the research and application of compound prescriptions.

Value and influencing factors of valid Traditional Chinese Medicine compound prescription patents for mammary gland hyperplasia

OBJECTIVE: To explore the value and factors influencing the maintenance of valid Traditional Chinese Medicine compound prescription patents for the management of mammary gland hyperplasia. METHODS: The State Intellectual Property Office Patents Database, China Patent Information Center Patents Database, Soopat Patent Search Platform, and CNIPR Search Platform of Chinese and Foreign Patent Database were searched to identify Traditional Chinese Medicine compound prescription patents for mammary gland hyperplasia that had been maintained for at least 5 years. Logistic regression analysis was used to detect the factors influencing the maintenance of valid patents. RESULTS: From 1 January 1993 to 31 December 2019, a total of 1228, Traditional Chinese Medicine compound prescription patents for mammary gland hyperplasia were authorized. Of these applications, 381 patents were granted and only 176 patents were maintained for more than 5 years. The five independent variables assessed in this study all had significant explanatory functions. CONCLUSIONS: The maintenance of valid patents for Traditional Chinese Medicine compound prescriptions for treating mammary gland hyperplasia is of great importance. The maintenance of such patents depends on many factors, such as the concentration of effective herbs, number of dependent claims, provision of new dosage forms and detailed experimental data, and transfer of patent rights.

Experimental Study on Effect of Compound Biejia Ruangan Prescription (复方鳖甲软肝方) on High Resolution Computerized Tomographic Images in Bleomycin Induced Pulmonary Fibrosis Rats

Objective: To study the therapeutic effect of Com pound Biejia Ruangan prescription (CBRP) on rat model with pulmonary fibrosis in duced by bleomycin. Methods: Fifty four male Sprague Dawley rats were rando mly divided into 6 groups (9 rats in each group). From the first day to the 28th day of the experiment, except to those in the sham model control group that were treated with normal saline, the same amount of bleomycin injection as the n ormal saline given to the control group was given through endotracheal instillat ion to all the rats in all the other groups. From the 29th day of the modeling, CBRP solution of different dosages was respectively injected into the rats in th e high, moderate and low CBRP dose group, while equal volume of normal saline w as given to those in the sham model control group and the model control group , and an equal volume of prednisone solution was given to rats in the prednisone group. On the 80th day, the high resolution computerized tomographic (HRCT) images were observed on an equal footing, and HRCT pathology was correlativel y studied. Results: Different HRCT pathological changes were shown in th e rats with pulmonary fibrosis, such as lung consolidation, thickening of interl obular septum and interlobular mesenchyma as well as lobular deformation, nodule shadow, abnormal brochiovascular tract, thickened pleura with irregular junctio n and polished glass like dense shadows. Honeycomb lung was observed in some cases. Pathological sections showed fibrotic proliferation of lung tissues and noticeable pulmonary interstitial fibrosis. CBRP could improve HRCT images of rats with pulmonary fibrosis, and lower fibrotic p roliferation of the lung tissue.Conclusion: CBRP plays its therapeutic role possibly through its effect on the structure of the lung in rats with pulmonary fibrosis.

Clinical efficacy of Chinese herbal compound in the treatment of infertility with kidney deficiency:A meta-analysis

Objective:Based on the current evidence system to evaluate the effect of traditional Chinese medicine compound on the clinical efficacy of infertility patients with kidney deficiency.Methods:Search the China Knowledge Resources Database(CNKI),Chinese Science and Technology Journal Database(VIP),China Academic Journal Database(Wanfang),PubMed,EMBASE,Ovid.The included studies are randomized controlled trials.The experimental group is Chinese medicine compound or Chinese medicine compound combined with western medicine,and the control group is western medicine.Two reviewers independently extracted and evaluated the literature data according to the Cochrane manual standards,and used Rev Man5.3 software for data synthesis and Meta-analysis.Results:32 studies were selected,a total of 2715 cases of infertility patients.The clinical pregnancy rate of the experimental group and the control group[n=29,OR(95%CI)=2.47(2.07,2.96),P<0.00001],the clinical total effective rate[n=20,OR(95%CI)=3.77(2.83,5.03),P<0.00001],TCM syndrome score[n=14,MD(95%CI)=4.34(3.08,5.61),P<0.00001],ovulation rate[n=20,OR(95%CI)=2.21(1.85,2.63),P<0.00001],the occurrence rate of two-way BBT[n=11,OR(95%CI)=2.65(2.02,3.48),P<0.00001].The GRADE scoring results show that the level of evidence is low and very low.Conclusion:Traditional Chinese medicine compound can increase the clinical pregnancy rate and clinical total effective rate of infertility with kidney deficiency syndrome,improve the scores of Chinese medical syndromes,increase its ovulation rate and the occurrence rate of BBT bidirectional type,and confirm the clinical efficacy of Chinese medicine compound from the perspective of evidence-based medicine.
