Whether or not treatment with antibiotics or probiotics for bacterial vaginosis (BV) is associated with a change in the diversity of vaginal microbiota in women was investigated. One hundred fifteen women, consisting of 30 healthy subjects, 30 BV-positive control subjects, 30 subjects with BV treated with a 7-day metronidazole regimen, and 25 subjects with BV treated with a 10-day probiotics regimen, were analyzed to determine the efficacy and disparity of diversity and richness of vaginal microbiota using 454 pyrosequencing. Follow-up visits at days 5 and 30 showed a greater BV cure rate in the probiotics-treated subjects (88.0 and 96 %, respectively) compared to the metronidazole-treated subjects (83.3 and 70 %, respectively [p = 0.625 at day 5 and p = 0.013 at day 30]). Treatment with metronidazole reduced the taxa diversity and eradicated most of the BV-associated phylotypes, while probiotics only suppressed the overgrowth and re-established vaginal homeostasis gradually and steadily. Despite significant interindividual variation, the microbiota of the actively treated groups or participants constituted a unique profile. Along with the decrease in pathogenic bacteria, such as Gardnerella, Atopobium, Prevotella, Megasphaera, Coriobacteriaceae, Lachnospiraceae, Mycoplasma, and Sneathia, a Lactobacillus-dominated vaginal microbiota was recovered. Acting as vaginal sentinels and biomarkers, the relative abundance of Lactobacillus and pathogenic bacteria determined the consistency of the BV clinical and microbiologic cure rates, as well as recurrent BV. Both 7-day intravaginal metronidazole and 10-day intravaginal probiotics have good efficacy against BV, while probiotics maintained normal vaginal microbiota longer due to effective and steady vaginal microbiota restoration, which provide new insights into BV treatment.

Background: The study aims to evaluate the effectiveness and safety of acupuncture therapy for asymptomatic infection of COVID-19. Methods: The following electronic databases will be searched from December 2019 to December 2020: MEDLINE, PubMed, EMBASE, Web of Science, China National Knowledge Infrastructure (CNKI), Wan-fang database, Chinese Scientific Journal Database (VIP), Chinese Biomedical Literature Databases (CBM), and other databases. All published randomized controlled trials (RCTs) about this topic will be included. Two independent researchers will operate article retrieval, duplication removing, screening, quality evaluation, and data analyses by Review Manager (V.5.3.5). Meta-analyses, subgroup analysis, and/or descriptive analysis will be performed based on the included data conditions. Results: High-quality synthesis and/or descriptive analysis of current evidence will be provided from the time of negative nucleic acid detection for 2 consecutive times (not on the same day), cure rate, converting to clinical diagnosis rate, and side effects of acupuncture. Conclusion: This study will provide the evidence of whether acupuncture is an effective and safe intervention for asymptomatic infection of COVID-19. PROSPERO registration number: CRD 42020179729.

Background: Coronavirus disease 2019 (COVID-19) is a rapidly spreading disease that has been in a public health emergency of international concern since its outbreak in 2020. Due to the complex pathogenesis and susceptibility of COVID-19, many commonly used drugs for the treatment of COVID-19 have not shown excellent clinical effects. Traditional Chinese medicine has a long clinical history of preventing and treating this respiratory infectious disease. Maxingshigan Decoction (MXSG) is widely used in China to treat COVID-19. However, there is no comprehensive and systematic evidence on the effectiveness and safety of Maxingshigan Decoction. Methods: PubMed, EMBASE, Clinical Trials, the Cochrane Library, Sino Med, and China National Knowledge Infrastructure up to September 2020. This study only screens clinical randomized controlled trials on MXSG for COVID-19 to evaluate its efficacy and safety. Data were extracted by 1 investigator and checked by an independent investigator. Review Manager 5.3 software was used for the data analysis. The dichotomous data is represented by relative risk, and the continuous is expressed by mean difference or standard mean difference, eventually the data is synthesized using a fixed effect model or a random effect model depending on whether or not heterogeneity exists. Results: The time from a positive diagnosis to a negative result of 2 consecutive nucleic acid tests (not on the same day), cure rate. The results of our research will be published in a peer-reviewed journal. Conclusion: The purpose of this systematic review is to provide new evidence for the effectiveness and safety of Maxingshigan decoction in the treatment of COVID-19.

Results: High-quality synthesis and/or descriptive analysis of current evidence will be provided from mortality rate, cure rate, the time of negative nucleic acid detection for 2 consecutive times (not on the same day), improvement of chest CT scans, disappearance time of fever and cough, and side effects. Conclusion: This study will provide the evidence of whether acupuncture is an effective and safe intervention for coronavirus disease 2019. PROSPERO registration number: CRD42020179298.

Background: The study aims to evaluate the effectiveness and safety of bloodletting therapy for herpes zoster. Methods: The following electronic databases will be searched from PubMed (1966 to March 2020), the Cochrane Central Register of Controlled Trials (update to March 2020), EMBASE (1980 to March 2020), China National Knowledge Infrastructure (1979 to March 2020), Wan Fang Data (1980 to March 2020), Chinese Scientific Journal Database (1989 to March 2020), Chinese Biomedical Database (1978 to March 2020) and traditional Chinese medicine Literature Analysis and Retrieval Database (1949 to March 2020). All randomized controlled trials without any limitation of blinding or publication language about this topic will be included, exclude cohort studies and case reports. Two independent researchers will operate article retrieval, duplication removing, screening, quality evaluation, and data analyses by Review Manager (V.5.3.5). Meta-analyses, subgroup analysis, and/or descriptive analysis will be performed based on the included data conditions. Results: High-quality synthesis and/or descriptive analysis of current evidence will be provided from cure rate, converting to clinical diagnosis rate, and side effects of bloodletting. Conclusion: This study will provide the evidence of whether bloodletting is an effective and safe intervention for herpes zoster. PROSPERO registration number: CRD42020171976
