[Systematic evaluation and sequential Meta-analysis of modified Xuefu Zhuyu Decoction combined with Western medicine in treatment of leiomyoma].

CNKI, PubMed and other databases were retrieved to extract eligible randomized controlled trial(RCT) about modified Xuefu Zhuyu Decoction(MXZD) combined with Western medicine(trial group) versus Western medicine alone(control group) in the treatment of leiomyoma. Therefore, a total of 25 RCTs were included, involving 2 328 patients. Bias risk evaluation tool in Cochrane Handbook 5.1.0 was used for evaluating the quality of these RCTs. Meta-analysis was performed for the reported indicators, including total efficiency, serum hormone level [progesterone(P), luteinizing hormone(LH), estradiol(E_2), follicle stimulating hormone(FSH)], uterine size, fibroids size and adverse reactions by using Stata 14.0 software. Meta-analysis showed that the total efficiency(RR=1.21,95%CI[1.17,1.25],P<0.05) of trial group was better than that of control group. Serum hormone level(WMD_P=-3.86,95%CI[-4.31,-3.41],P<0.05; WMD_(LH)=-3.64,95%CI[-4.47,-2.82],P<0.05; WMD_(E_2)=-39.99,95%CI[-53.45,-26.52],P<0.05; WMD_(FSH)=-3.79,95%CI[-4.86,-2.72],P<0.05), uterine size(WMD=-50.02,95%CI[-55.98,-44.06],P<0.05), fibroids size(WMD=-15.79,95%CI[-18.11,-13.46],P<0.05) and adverse reactions(RR=0.65,95%CI[0.48,0.88],P<0.05) of trial group were all lower than those of control group, with statistical significances. Trial sequential analysis(TSA) was performed by using TSA 0.9 software, and showed a reliable therapeutic effect of the experimental group. In short, our study indicated that modified Xuefu Zhuyu Decoction combined with Western medicine had a better therapeutic effect on leiomyoma than Western medicine alone, but more high-quality studies are needed to verify this conclusion in the future.

Berberine attenuates septic cardiomyopathy by inhibiting TLR4/NF-κB signalling in rats.

CONTEXT: Berberine (Ber) can increase the survival rate of septic mice and inhibit inflammation, but whether it has a protective effect on septic cardiomyopathy (SCM) is unclear. OBJECTIVE: To investigate whether Ber ameliorates SCM in a rat model and its potential mechanism. MATERIALS AND METHODS: Male SD rats were randomly divided into three groups: control (Con, n = 6) (DD H2O, 2 mL/100 g, ig, qd × 3 d, then saline, 10 mg/kg, ip); sepsis [LPS (lipopolysaccharide), n = 18] (LPS 10 mg/kg instead of saline, ip); and berberine intervention (Ber, n = 18) (Ber, 50 mg/kg instead of DD H2O, ig, qd × 3 d, LPS instead of saline, ip). Hemodynamics, HE staining, ELISA and western blot were performed at 6, 24, and 48 h after intraperitoneal injection of LPS to evaluate the effect of berberine in septic rats. RESULT: Berberine could recover myocardial injury by partially increased ± dp/dt max (1151, 445 mmHg/s) and LVEDP levels (1.49 mmHg) with LPS-induced rats, as well as an ameliorated increase of cTnT (217.53 pg/mL) in the Ber group compared with that in the LPS group (at 24 h). In addition, HE staining results showed that berberine attenuated the myocardial cell swelling induced by LPS. In contrast to the LPS group, the up-regulation of TLR4, p65 TNF-α, and IL-1ß were attenuated in the Ber group. DISCUSSION AND CONCLUSIONS: Berberine showed a protective effect on septic cardiomyopathy rats possibly through inhibiting the activation of TLR4/NF-κB signalling pathway. Whether it improves SCM through other mechanisms is our ongoing research.

Exploring the Potential Mechanism of Shufeng Jiedu Capsule for Treating COVID-19 by Comprehensive Network Pharmacological Approaches and Molecular Docking Validation.

OBJECTIVE: Shufeng Jiedu capsule (SFJDC) is a well-known Chinese patent drug that is recommended as a basic prescription and applied widely in the clinical treatment of COVID-19. However, the exact molecular mechanism of SFJDC remains unclear. The present study aims to determine the potential pharmacological mechanisms of SFJDC in the treatment of COVID-19 based on network pharmacology. METHODS: The network pharmacology-based strategy includes collection and analysis of active compounds and target genes, network construction, identification of key compounds and hub target genes, KEGG and GO enrichment, recognition and analysis of main modules, as well as molecule docking. RESULTS: A total of 214 active chemical compounds and 339 target genes of SFJDC were collected. Of note, 5 key compounds (ß -sitosterol, luteolin, kaempferol, quercetin, and stigmasterol) and 10 hub target genes (TP53, AKT1, NCOA1, EGFR, PRKCA, ANXA1, CTNNB1, NCOA2, RELA and FOS) were identified based on network analysis. The hub target genes mainly enriched in pathways including MAPK signaling pathway, PI3K-Akt signaling pathway and cAMP signaling pathway, which could be the underlying pharmacological mechanisms of SFJDC for treating COVID-19. Moreover, the key compounds had high binding activity with three typical target proteins including ACE2, 2OFZ, and 1SSK. CONCLUSION: By network pharmacology analysis, SFJDC was found to effectively improve immune function and reduce inflammatory responses based on its key compounds, hub target genes, and the relevant pathways. These findings may provide valuable evidence for explaining how SFJDC exerting the therapeutic effects on COVID-19, providing a holistic view for further clinical application.

Can network pharmacology identify the anti-virus and anti- inflammatory activities of Shuanghuanglian oral liquid used in Chinese medicine for respiratory tract infection?

INTRODUCTION: Shuanghuanglian (SHL) oral liquid is a well-known traditional Chinese medicine preparation administered for respiratory tract infections in China. However, the underlying pharmacological mechanisms remain unclear. The present study aims to determine the potential pharmacological mechanisms of SHL oral liquid based on network pharmacology. METHODS: Network pharmacology-based strategy including collection and analysis of putative compounds and target genes, network construction, Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway, and Gene Ontology (GO) enrichment, identification of key compounds and target genes, and molecule docking was performed in this study. RESULTS: A total of 82 bioactive compounds and 226 putative target genes of SHL oral liquid were collected. Of note, 28 hub target genes including 4 major hub target genes: estrogen receptor 1 (ESR1), nuclear receptor coactivator 2 (NCOA2), nuclear receptor coactivator 1 (NCOA1), androgen receptor (AR) and 5 key compounds (quercetin, luteolin, baicalein, kaempferol and wogonin) were identified based on network analysis. The hub target genes mainly enriched in pathways including PI3K-Akt signaling pathway, human cytomegalovirus infection, and human papillomavirus infection, which could be the underlying pharmacological mechanisms of SHL oral liquid for treating diseases. Moreover, the key compounds had great molecule docking binding affinity with the major hub target genes. CONCLUSION: Using network pharmacology analysis, SHL oral liquid was found to contain anti-virus, anti-inflammatory, and "multi-compounds and multi-targets" with therapeutic actions. These findings may provide a valuable direction for further clinical application and research.
