农村女性公共参与是妇女发展的重要内容。随着基层治理转型,农村女性不但在村干部职数中占比增加,而且越来越多女性占据权力结构核心地位,村庄层面“妇女当家”现象明显。与男性村干部相比,女性村干部注重服务意识、以心换心,能够守规矩有底线,女性参与村级治理具有柔性治理、情感治理和规范治理特征。基层治理转型下村级行政化和村干部职业化,村庄内部事务由利益纠纷型转向社会动员型,女性为谋求效用最大化的家庭发展策略,主动参与到村级治理中,满足其经济、抚育和赡养等多重复合性目标。从影响来看,农村女性参与村级治理有助于构建回应型基层政府和平权型村级权力结构,促进多元共治格局,提升女性村庄话语权。随着越来越多农村女性成为村干部,政府应该加强乡村治理中的女性领导力,为女性村干部提供有利的外部支持系统。

Insufficient therapeutic strategies for acute kidney injury(AKI)necessitate precision therapy targeting its *** study reveals the new mechanism of the marine-derived anti-AKI agent,piericidin glycoside S14,targeting peroxiredoxin 1(PRDX1).By binding to Cys83 of PRDX1 and augmenting its peroxidase activity,S14 alleviates kidney injury efficiently in Prdx1-overexpression(Prdx1-OE)***,S14 also increases PRDX1 nuclear translocation and directly activates the Nrf2/HO-1/NQO1 pathway to inhibit ROS *** to the limited druggability of S14 with low bioavailability(2.6%)and poor renal distribution,a pH-sensitive kidney-targeting dodecanaminechitosan nanoparticle system is constructed to load S14 for precise treatment of AKI.L-Serine conjugation to chitosan imparts specificity to kidney injury molecule-1(Kim-1)-overexpressed *** developed S14-nanodrug exhibits higher therapeutic efficiency by improving the in vivo behavior of S14 *** encapsulation with micelles,the AUC_(0-t),half-life time,and renal distribution of S14 increase 2.5-,1.8-,and 3.1-fold,*** main factors contributing to the improved druggability of S14 nanodrugs include the lower metabolic elimination rate and UDPglycosyltransferase(UGT)-mediated *** summary,this study identifies a new therapeutic target for the marine-derived anti-AKI agent while enhancing its ADME properties and druggability through nanotechnology,thereby driving advancements in marine drug development for AKI.

Background: Studies of gastrointestinal (GIT) cancers have shown that circZFR could be involved in the development and progression of various GIT cancers. However, small sample sizes limit the clinical significance of these studies. Here, a meta-analysis was conducted to ascertain the actual involvement of circZFR in the development and prognosis of GIT cancers. Methods: PubMed, Embase, Web of Science, and the Cochrane Library were searched up to December 31, 2023. Hazard ratios (HRs) or odds ratios (ORs) with 95% confidence intervals (CIs) were pooled to evaluate the association between circZFR expression and overall survival (OS). Publication bias was measured using the funnel plot and Egger’s test. Results: 10 studies having 659 participants were enrolled for meta-analysis. High circZFR expression was associated with poor OS (HR = 1.4, 95% CI: 1.20, 1.70). High circZFR expression also predicted larger tumor size (OR = 4.38, 95% CI 2.65, 7.25), advanced clinical stage (OR = 5.33, 95% CI 3.10, 9.16), and tendency for distant metastasis (OR = 2.89, 95% CI: 1.62, 5.11), but was not related to age, gender, and histological grade. Conclusions: In summary, high circZFR expression was associated with poor OS, larger tumor size, advanced stage cancer and tendency for distant metastasis. These findings suggested that circZFR could be a prognostic marker for GIT cancers.
