Objectives As current evidence of the effectiveness on acupuncture for primary dysmenorrhea (PD) is inconsistent, we aimed to critically appraise the evidence from relevant systematic reviews (SRs). Methods SRs of randomized controlled trials (RCTs) concerning acupuncture and PD were searched in four databases. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) and latest Assessment of Multiple Systematic Reviews 2 (AMSTAR2) checklists were used to assess reporting characteristics and methodological quality, respectively. Results The literature search yielded 38 potential records, of which five met the inclusion criteria. The total average (SD) for PRISMA was 20.60 (1.14) out of 27. All five SRs have more than one critical weakness in AMSTAR2, so their methodological qualities were considered as critically low. The most frequent problems included nonregistration of study protocol, absence of a list of excluded studies, and unclear acknowledgment of conflicts of interests. The three studies of higher methodological quality reported positive results in pain relief. Conclusion The reporting and methodological quality of systematic reviews and meta-analysis studies were suboptimal, which demands further improvement. More efforts are needed to improve validity of systematic reviews and RCTs in this area.
Background. Ulcerative colitis (UC), a chronic and nonspecific inflammatory bowel disease, seriously affects the quality of patients’ life. Han Re Bing Yong Fa (treating diseases with both cool- and warm-natured herbs) is a classical therapeutic principle of traditional Chinese medicine (TCM), which is often used to treat chronic diseases, including UC. The Gan Jiang-Huang Qin-Huang Lian-Ren Shen decoction (GJHQHLRSD), a representative of Han Re Bing Yong Fa, is effective in alleviating inflammatory symptoms in UC. However, the pharmacological mechanism underlying its anti-inflammatory effect remains unclear. Methods. A network pharmacology strategy, including the construction and analysis of the drug–disease network, was used to explore the complex mechanism of GJHQHLRSD treatment of UC. In addition, molecular docking technology was used to preliminarily examine the binding ability of the potential active components and core therapeutic targets of GJHQHLRSD. Results. The network pharmacology results revealed 140 targets of GJHQHLRSD which are involved in UC. The PPI network analysis identified seven target genes: BCL2L1, NR3C1, ALOX5, S1PR5, NR1I2, CYP2D6, and LPAR6. The molecular docking results revealed that the following displayed strongest combined effects: EGFR with kaempferol, ERK1 with worenine, STAT3 with Palmidin A, BCL2L1 with diop and VEGFA with ginsenoside Rg3. The KEGG and gene ontology enrichment analyses results indicated that GJHQHLRSD functions by regulating the EGFR signaling pathway in UC treatment. Other effective biological processes involved in UC treatment included cancer-related as well as inflammation and viral infection signaling pathways, such as the “MicroRNAs in cancer,” “TNF signaling pathway,” and “JAK-STAT signaling pathway.” Conclusions. This study reflects the multicomponent, multitarget, and multipathway characteristics of the action mechanism of GJHQHLRSD in treating UC. Furthermore, it helps better understand the TCM therapeutic principle of Han Re Bing Yong Fa and explore novel candidate drug targets for UC treatment.
Background: Traditional Chinese medicine (TCM) nonpharmacological interventions are gaining an increasing popularity for chronic pulmonary obstructive disease (COPD) treatment and rehabilitation, yet their comparative effectiveness and safety remains unclear. Therefore, this study will aim to compare their effectiveness and safety for COPD by implementing a network-meta analysis. Methods: Electronic databases including MEDLINE via Ovid, and EMBASE via Ovid, the Cochrane Central Register of Controlled Trials (CENTRAL), China National Knowledge Infrastructure (CNKI) and Chinese BioMedical Literature Database (CBM) will be searched for related randomized controlled trials (RCTs) from inceptions to the search date without language restrictions. RCTs that compare TCM nonpharmacological interventions with placebo or conventional treatments will be included. The primary outcome will be lung function measures, dyspnea level and COPD-specified life quality and secondary ones will include functional exercise capacity, and general health-related life quality. Both classical meta-analysis and network meta-analysis will be implemented to investigate direct and indirect evidences on this topic. Continuous data will be expressed as standard mean differences (SMDs) and categorical data as risk ratios (RRs) with 95% confidence intervals. The evidence transitivity and consistency within network will be evaluated with Cochrane Q statistic and net-heat plot. Results: The study results will be disseminated through a peer-reviewed journal publication or conference presentation. Conclusions: The review findings will provide a ranking evidence of current TCM nonpharmacological interventions and help to inform clinical practitioners, COPD patients, and policy-makers in the decision-making.
