Objective:To summarize Chinese materia medica with estrogen-activity based on data mining and analyze their characteristics.Methods:Literature was retrieved from CNKI, Wanfang Data, Chongqing VIP, CBM, PubMed and Web of Science from the establishment of the databases to June 30, 2024, and Chinese materia medica with estrogenic activity were screened. Excel 2021 and KH Coder 3.0 software were used to perform statistical and network co-occurrence analysis on the efficacy classification of Chinese materia medica, properties, tastes and meridians, screening methods for estrogen activity, and applications.Results:Totally 121 kinds of Chinese materia medica with estrogen-activity were included in total. The efficacy classifications were mostly tonic medicines, heat-clearing medicines and blood circulation promoting drugs. The properties were mainly warm and neutral, the tastes were mainly sweet and bitter, and the meridians were mainly the liver, kidney and spleen meridians. The network co-occurrence analysis of the efficacy classification, properties, tastes and tropism meridians showed that the clustering relationship of tonic medicine-neutral-sweet-liver-kidney was the most obvious. The screening methods mainly included MCF-7 cell proliferation and uterine weight gain experiments. Their applications mainly covered osteoporosis, perimenopausal syndrome, lipid metabolism disorder, and premature ovarian failure, etc.Conclusions:Chinese materia medica with estrogen-activity or their components act on estrogen target cells or organs to exert estrogen-like or antagonistic estrogenic effects. This kind of Chinese materia medica can regulate the body's qi, blood, yin and yang, the function of organs and the fullness of Tiangui, as well as the Chong meridian and Conception Vessel, thus improving human growth and development, reproduction and aging. In the future, it is suggested to explore their effective components, mechanisms, bidirectional effect and safety on the basis of guiding clinical medication with the theory of TCM, combining with modern medical research techniques and evidence-based medical research.

The incidence of age-related macular degeneration(AMD)is rising with the intensifying aging trend,be-coming a critical challenge that demands urgent solutions.Dry AMD(dAMD)accounts for approximately 80％of all AMD cases,and there is currently a lack of highly effective treatment options.In recent years,traditional Chinese medicine(TCM)has been proven to effectively treat dAMD through actions such as antioxidation,anti-apoptosis,anti-inflammation,and lipid-lowering.By reviewing domestic and international literature,this article discusses TCM monomers,extracts,and compound formulations for dAMD,analyzing their various mechanisms.Based on traditional TCM efficacy theories and in-tegrated with modern mechanisms of action,it targets the active components of TCM to elucidate the connection between effective medicinal targets of TCM and dAMD,thereby clarifying the efficacy and scientific basis of TCM monomers,com-pounds,and extracts in treating dAMD.The aim is to provide new perspectives for the prevention and clinical treatment of dAMD.

Objective The purpose of this study was to investigate the bacterial communities of biting midges and ticks collected from three sites in the Poyang Lake area,namely,Qunlu Practice Base,Peach Blossom Garden,and Huangtong Animal Husbandry,and whether vectors carry any bacterial pathogens that may cause diseases to humans,to provide scientific basis for prospective pathogen discovery and disease prevention and control. Methods Using a metataxonomics approach in concert with full-length 16S rRNA gene sequencing and operational phylogenetic unit(OPU)analysis,we characterized the species-level microbial community structure of two important vector species,biting midges and ticks,including 33 arthropod samples comprising 3,885 individuals,collected around Poyang Lake. Results A total of 662 OPUs were classified in biting midges,including 195 known species and 373 potentially new species,and 618 OPUs were classified in ticks,including 217 known species and 326 potentially new species.Surprisingly,OPUs with potentially pathogenicity were detected in both arthropod vectors,with 66 known species of biting midges reported to carry potential pathogens,including Asaia lannensis and Rickettsia bellii,compared to 50 in ticks,such as Acinetobacter lwoffii and Staphylococcus sciuri.We found that Proteobacteria was the most dominant group in both midges and ticks.Furthermore,the outcomes demonstrated that the microbiota of midges and ticks tend to be governed by a few highly abundant bacteria.Pantoea sp7 was predominant in biting midges,while Coxiella sp1 was enriched in ticks.Meanwhile,Coxiella spp.,which may be essential for the survival of Haemaphysalis longicornis Neumann,were detected in all tick samples.The identification of dominant species and pathogens of biting midges and ticks in this study serves to broaden our knowledge associated to microbes of arthropod vectors. Conclusion Biting midges and ticks carry large numbers of known and potentially novel bacteria,and carry a wide range of potentially pathogenic bacteria,which may pose a risk of infection to humans and animals.The microbial communities of midges and ticks tend to be dominated by a few highly abundant bacteria.

BackgroundDue to the COVID-19 pandemic， both teenagers' studies and personal life are critically affected， which has resulted in a variety of mental health problems. In this regard， scholars at home and abroad have carried out a large number of research concerning adolescent mental health， of which there still exists a lack of systematic combing and review. ObjectiveTo understand the status and development trend of research on adolescent mental health during the COVID-19 pandemic at home and abroad， and to grasp the current research hotspots and trends in this field， so as to provide references for relevant research and practice in the post-epidemic era. MethodsOn October 30， 2022， we searched through China Knowledge Network Infrastructure （CNKI） and Web of Science database， and the publishing time of articles to be retrieved was limited between December 1， 2019 and October 30， 2022. Excel and CiteSpace were used to perform visual analysis on these articles in terms of number， author， institution， country and keywords of the articles. ResultsA total of 7 608 articles were included. At home and abroad， the number of papers related to adolescent mental health generally increased at first and then decreased under the pandemic situation. Compared with foreign countries， the connection and cooperation among domestic scholars and institutions was not close enough. The top three countries in the number of English literature published were the United States， Britain and China， and those in intermediary center were Tunis， Cameroon and Anguilla. The parent-child relationship and mental health of teenagers during were much concerned by scholars both at home and abroad. With the passage of time， researchers at home and abroad had shifted their focus from only negative factors to positive factors. ConclusionChinese scholars or institutions need to strengthen more domestic and international exchanges and cooperation. Scholars from different countries can carry out cross-cultural study on research topics of common concern， and continue to explore the positive psychological changes of teenagers in the post-epidemic era.［Funded by National Social Science Foundation 2020 Education Youth Project of 13th Five-Year Plan （number， CHA200259）］

Objective To investigate the status of health knowledge of patients after percutaneous coronary intervention (PCI) and its influencing factors, so as to provide a scientific basis for formulating targeted health education programs. Methods Using a self-designed questionnaire on health cognition after PCI, 433 patients with a history of PCI surgery at a Grade III, Class A hospital between January 2019 and December 2019 were selected as the research subjects to investigate their health cognition and the influencing factors by binary logistic regression analysis. Results The pass rate of health cognition of patients after PCI was 39%, and the total correct rate was 57.5%. The correct rate of drug knowledge and risk factors was the lowest (33.6% and 48.5%, respectively). Binary logistic regression showed that gender, age and cardiac function classification were risk factors for health cognition of patients after PCI, while education level, occupation category and recurrence of discomfort after PCI were protective factors. Conclusion The level of health cognition of patients after PCI is low. Gender, age, education level, occupation category, cardiac function classification and recurrence of discomfort after PCI are independent influencing factors. When implementing health education, medical staff should comprehensively consider the formulation of individualized health education to help.
