The growth of dendrites and the side reactions occurring at the Zn anode pose significant challenges to the commercialization of aqueous Zn-ion batteries（AZIBs）. These challenges arise from the inherent conflict between mass transfer and electrochemical kinetics. In this study, we propose the use of a multifunctional electrolyte additive based on the xylose（Xylo） molecule to address these issues by modulating the solvation structure and electrode/electrolyte interface, thereby stabilizing the Zn anode. The introduction of the additive alters the solvation structure, creating steric hindrance that impedes charge transfer and then reduces electrochemical kinetics. Furthermore, in-situ analyses demonstrate that the reconstructed electrode/electrolyte interface facilitates stable and rapid Zn2+ion migration and suppresses corrosion and hydrogen evolution reactions. As a result, symmetric cells incorporating the Xylo additive exhibit significantly enhanced reversibility during the Zn plating/stripping process, with an impressively long lifespan of up to 1986 h, compared to cells using pure ZnSO4electrolyte. When combined with a polyaniline cathode, the full cells demonstrate improved capacity and long-term cyclic stability. This work offers an effective direction for improving the stability of Zn anode via electrolyte design, as well as highperformance AZIBs.

目的了解艾滋病抗病毒治疗对单阳配偶间人类免疫缺陷病毒(HIV)传播的影响。方法采取回顾性队列研究的方法,选择百色市2005~2014年797例艾滋病患者及其未感染HIV的配偶为研究对象,根据患者接受抗病毒治疗状态分为治疗组和未治疗组随访观察阴性配偶的HIV转归,按患者不同年随访时间和基线特征分别计算阴性配偶每100人年HIV阳转率,并运用COX比例风险模型来评估治疗的风险比,运用KaplanMeier分析HIV阴性配偶仍保持阴性的概率。结果在HIV血清结果不一致的797例阳性配偶中,治疗组与未治疗组患者分别为487例和310例,平均年龄分别为(41.234±12.326)和(36.903±12.267)岁,基线CD4^+T淋巴细胞计数分别为(222.856±145.112)和(514.900±233.792)个/mm^3,中位随访时间分别为29(IQR:15~46)和31个月(IQR:18~52),两组均以男性、18~44岁、高中以下化程度、已婚、农民及农民工、壮族和异性性途径感染为主。随访期间共33例阴性配偶发生HIV阳转,阳转率为1.414/100人年,其中治疗组HIV阳转12例,阳转率为0.881/100人年,非治疗组HIV阳转21例,阳转率为2.159/100人年,经抗病毒治疗后配偶间HIV传播的危险性降低68.2%[AHR=0.318,(95%CI:0.125,0.807)],但抗病毒治疗对配偶间HIV传播的保护性作用有统计学意义仅是随访的第2年[AHR=0.157,(95%CI:0.031,0.786)]。结论在当前社会环境下,抗病毒治疗对预防配偶间HIV传播作用显著,但这种保护作用的持久性在桂西少数民族山区乃至发展中国家仍需进一步观察和研究,才能更好地推广治疗即预防的公共卫生策略。
