Premature ovarian insufficiency （POI） is a reproductive endocrine disorder that severely affects female reproductive health. However， there remains a lack of clinically effective and safe therapeutic options to restore ovarian function. Traditional Chinese medicine （TCM）， with its advantages of multi-component and multi-target holistic regulation， has shown unique potential in the prevention and treatment of POI. Among TCM monomers， curcumin， resveratrol， and icariin exert antioxidant， anti-inflammatory， and anti-ovarian granulosa cell apoptosis effects by regulating signaling pathways such as nuclear factor-erythroid 2-related factor 2/heme oxygenase-1， phosphoinositide 3-kinase/protein kinase B， and mitogen-activated protein kinase. Single TCM herbs， including American ginseng， Cuscutae Semen， and Cistanches Herba， can regulate sex hormone levels， and alleviate ovarian oxidative stress and immune damage. TCM compound formulas such as Yijing decoction， Siwu decoction， Zuogui pill， and Kuntai capsule modulate multiple signaling pathways， including vascular endothelial growth factor/vascular endothelial growth factor receptor-2， phosphoinositide 3-kinase/protein kinase B/mammalian target of rapamycin， and silence information regulator 1/p53， thereby promoting angiogenesis， inhibiting mitochondrial apoptosis， and regulating autophagy and ferroptosis， which ultimately delay follicular atresia and improve ovarian reserve function. Further studies are suggested to apply artificial intelligence to deeply explore the underlying mechanisms and carry out high-quality clinical trials， so as to promote the standardized application of TCM in the prevention and treatment of POI.

A prediction model for the risk of childhood allergic asthma was established through the analysis of public datasets. By using bioinformatics analysis methods, two datasets, GSE40732 and GSE40888, were selected, which included the whole-genome expression profile data of 222 children. Among them, GSE40732 was used as the training dataset to detect differentially expressed genes in peripheral blood mononuclear cells of children with the disease, and the master regulator analysis (MRA) algorithm was used to screen the master regulator genes in the inflammation-related pathway (GO: 0006954). After obtaining the master regulator genes, the expression of these master regulator genes in the GSE40732 and GSE40888 datasets was detected, and a prediction model was constructed through logistic regression, based on which risk scores were assigned to children. By comparing the risk scores of healthy children and children with the disease, the area under the curve (AUC) was used to evaluate the classification performance of the model. The average value of the risk scores of all children with the disease output by the model was calculated as the threshold. According to this threshold, the children with the disease in the two datasets were divided into high-risk and low-risk groups. The CIBERSORT algorithm was applied to analyze the infiltration of immune cells in the high-risk and low-risk groups, and the enrichment analysis of signaling pathways was completed using the msigdbr package in R software. The results showed that compared with healthy children, there were 377 up-regulated genes and 255 down-regulated genes in the peripheral blood mono-nuclear cells of children with the disease. The MRA algorithm analysis showed that there were five genes ( MUC5B, CST4, CCR7, TNF-α, and THBS1) that were the master regulator genes in the regulatory network. Risk score= MUC5B×3.47 +CST4×2.17 +CCR7×0.59 +TNF- α×0.54 +THBS1×1.67. The AUC in the GSE40732 and GSE40888 datasets were 0.874 and 0.682, respectively. Compared with the low-risk group, the resting memory CD4 +T cells and regulatory T cells in the peripheral blood of children with the disease in the high-risk group significantly decreased ( P<0.05), and both the IL-33 and IL-13 pathways were highly enriched. In conclusion, the model constructed in this study has a good predictive efficiency for the risk of allergic asthma and also has a certain effect on risk stratification.

Objective:To determine the relationship between health self-empowerment level and health self-management skill in older adults.Methods:A household survey was conducted from June 2020 to April 2021, among older adults in two communities each in Zhuzhou and Changsha selected by stratified cluster sampling. Data were collected through a general questionnaire, simplified. Elders Health Empowerment Scale, and Rating Scale of Health Self-Management Skill for Adults. A total of 444 questionnaires were distributed, of which 425 were valid. Pearson correlation and hierarchical regression analyses were used to analyze the relationship between health self-empowerment level and health self-management skill.Results:Final sample included 425 elderly people. Health self-empowerment was at medium to high level (30.9±5.6), whereas health self-management was at medium level (146.2±21.7); and the two factors were significantly correlated (Pearson coefficient was 0.724). After controlling for confounding factors (demographic characteristics), health self-empowerment independently accounted for 34.3% of the variation in health self-management ability.Conclusion:Health self-empowerment positively affects health self-management ability among older adults, which suggests the importance of stimulating health self-empowerment awareness in the process of health self-management.
