Objective To systematically evaluate and sequentially analyze the clinical efficacy and safety of Baogong Zhixue Granules for the treatment of abnormal uterine bleeding due to ovulation disorder.Methods The randomized controlled trials(RCTs)of Baogong Zhixue Granules for the treatment of abnormal uterine bleeding due to ovulation disorder were retrieved from the databases of CNKI,Wanfang Data,VIP,China Biology Medicine,PubMed,Embase,and Cochrane Library from the establishment of the databases to January 5th,2023.Literature screening and data extraction were conducted according to Cochrane Handbook for Systematic Reviews of Interventions,and Meta-analysis was performed by RevMan 5.4.Results Totally 15 articles were included,involving 1 425 patients.Meta-analysis results showed that Baogong Zhixue Granules could effectively improve the clinical efficacy of abnormal uterine bleeding due to ovulatory disorder(RR=1.17,95%CI[1.13,1.23],P<0.000 01),shorten hemostasis time[bleeding control time(MD=-6.35,95%CI[-8.89,-3.81],P<0.000 01),complete hemostasis time(MD=-12.56,95%CI[-16.22,-8.89],P<0.000 01)],reduce endometrial thickness(MD=-1.26,95%CI[-1.71,-0.80],P<0.000 01),reduce hemoglobin loss(MD=13.35,95%CI[11.41,15.29],P<0.000 01),improve the score of uterine bleeding(MD=-2.22,95%CI[-2.43,-2.01],P<0.000 01),and reduce the recurrence of disease(RR=0.37,95%CI[0.19,0.72],P=0.004).There was no statistical significance between the test group and the control group in terms of adverse reactions(P=0.82).The trial sequential analysis of the total efficiency was carried out,and the cumulative included research passed the traditional threshold and trail sequential analysis threshold.Conclusion Baogong Zhixue Granules have a certain clinical efficacy in the treatment of abnormal uterine bleeding due to ovulation disorder,but there may be publication bias in the study,and higher quality clinical RCTs need to be carried out.

Brain science accelerates the study of intelligence and behavior, contributes fundamental insights into human cognition, and offers prospective treatments for brain disease. Faced with the challenges posed by imaging technologies and deep learning computational models, big data and high-performance computing (HPC) play essential roles in studying brain function, brain diseases, and large-scale brain models or connectomes. We review the driving forces behind big data and HPC methods applied to brain science, including deep learning, powerful data analysis capabilities, and computational performance solutions, each of which can be used to improve diagnostic accuracy and research output. This work reinforces predictions that big data and HPC will continue to improve brain science by making ultrahigh-performance analysis possible, by improving data standardization and sharing, and by providing new neuromorphic insights.

The accelerating growth of the public microbial genomic data imposes substantial bur-den on the research community that uses such resources. Building databases for non-redundant ref-erence sequences from massive microbial genomic data based on clustering analysis is essential. However, existing clustering algorithms perform poorly on long genomic sequences. In this article, we present Gclust, a parallel program for clustering complete or draft genomic sequences, where clustering is accelerated with a novel parallelization strategy and a fast sequence comparison algo-rithm using sparse suffix arrays (SSAs). Moreover, genome identity measures between two sequences are calculated based on their maximal exact matches (MEMs). In this paper, we demon-strate the high speed and clustering quality of Gclust by examining four genome sequence datasets. Gclust is freely available for non-commercial use at https://github.com/niu-lab/gclust. We also introduce a web server for clustering user-uploaded genomes at http://niulab.scgrid.cn/gclust.

Objective To explore the characteristics of opportunistic infections(OIs)in HIV-infected indi-viduals with suboptimal immune reconstitution after ART treatment so as to provide a reference for preventing and managing HIV infections.Methods The clinical data including opportunistic infections specifically were acquired from 112 HIV-infected individuals with suboptimal immune reconstitution from the outpatient department of Wuming Hospital,Guangxi Medical University.The impact of baseline CD4+T lymphocyte counts on the incidence,type,and mixed infection rates of the opportunistic infections were analyzed.Results The opportunistic infection rate among the 112 HIV-infected individuals with suboptimal immune reconstitution was 42.86%,among which fungal infections were the most commonly seen.The opportunistic infection rate of the patients with a baseline of CD4+T lymphocyte counts≤50/μL was significantly higher than that of the patients with a baseline of CD4+T lymphocyte counts>50/μL,and there was no significant difference in the type of opportunistic infections as well as the rate of mixed infections.Conclusion HIV-infected people with suboptimal immune reconstitution in Guangxi are susceptible to HIV OIs.Among them,the group with a baseline CD4+ T lymphocyte counts≤50/μL has a higher rate of OIs,mainly fungal infections.

Objective:Using the Taqman low-density array (TLDA) to develop a detection method which can rapidly type influenza A virus and the subtypes of H1-H16 and N1-N9, which is suitable for rapid typing and identification of influenza A in influenza like cases and avian influenza samples.Methods:The primers and probes of influenza A, H1-16 subtypes, N1-9 subtypes were designed and pre-customized on the TLDA reaction chip; Optimize the TLDA annealing temperature; The sensitivity of TLDA was evaluated by 10 fold gradient dilution of influenza A virus nucleic acid of various subtypes and the digital PCR; The specificity of the TLDA was verified by influenza B, adenovirus, respiratory syncytial virus and other respiratory viruses. At the same time, a variety of influenza A viruses that have been clearly typed were selected to evaluate the specificity and effectiveness of TLDA; The TLDA was used to detect 16 samples of influenza like cases and 24 samples of external environment of avian influenza.Results:The best annealing temperature of TLDA was 60 ℃, the detection sensitivity of TLDA was between 1.52 and 8.00 copies/μl for H1N1, H3N2, H5N6, H7N9 and H9N2, there was no specific cross reaction with influenza B, avian influenza, adenovirus, respiratory syncytial virus and other respiratory viruses. A total of 12 influenza positive samples and 24 samples from environmental surveillance of avian influenza were detected by TLDA, all of the result of samples were correct in typing.Conclusions:The high-throughput detection method of influenza A virus based on TLDA has good sensitivity and specificity, and the result of clinical samples show that the TLDA is suitable for rapid detection of influenza like cases and avian influenza samples, especially for rapid subtype screening and identification of new influenza A virus that cannot be identified by conventional commercial kits.

Objective:To explore the associations between perceived built environment attributes and adults’ leisure-time physical activity in four cities of China.Methods:Multistage cluster random sampling method was used to select adults aged 25 to 64 in Hangzhou, Suzhou, Chengdu, and Qingdao. Data were collected from June 2017 to July 2018. The perception of the urban built environment was assessed by the neighborhood environment walkability scale-abbreviated (NEWS-A), and the physical activity was assessed by the International Physical Activity Questionnaire. Generalized linear mixed models were used to explore the relationship between the perceived built environment and leisure-time physical activities.Results:A total of 3 789 participants were included in the analysis. After adjusting for potential confounders, better access to public services ( OR=1.34, 95% CI: 1.02-1.75) and higher aesthetic quality ( OR=1.37, 95% CI: 1.09-1.73) were positively associated with the possibility of engaging in leisure-time physical activity in the past week. Similarly, these two attributes were positively associated with leisure-time walking. Higher scores on the perception of street connectivity were positively associated with leisure-time walking [ exp( β)=1.09, 95% CI: 1.00-1.19]. Higher residential density [ exp( β)=1.000 4, 95% CI:1.000 0-1.000 8], better access to physical activity destinations[ exp( β)=1.09, 95% CI: 1.00-1.19], and better aesthetics [ exp( β)=1.11, 95% CI:1.00-1.22] were associated with higher leisure-time physical activity. Similarly, these three attributes were positively associated with the possibility of meeting the WHO recommendations. Conclusion:Changing some urban built environment attributes may increase leisure-time physical activity.
