The potential harm of organic pollutants in drinking water to human health is widely focused on in the wodd; more and more pollutants with genotoxic substances are released into the aquatic environment. Water source samples were collected from 7 different localities of Nanjing City. The potential genotoxicity of organic extracts from drinking water sources were investigated by means of the comet assay in human peripheral lymphocytes. The results showed that all the organic extracts from all the water source samples could induce DNA damages of human peripheral blood lymphocytes at different levels. A significant difference （P 〈 0.01） was observed when compared with the solvent control, The DNA damage increased with the increase of the dosage of the original water source. Significant differences of DNA damage were observed in different drinking water sources, as shown by the multiple comparisons analysis at the dosage of 100x; the degree of DNA damage treated by Hushu waterworks （at town level） was the most serious, the arbitrary units （AU） was 141.62±6.96, however, that of Shangyuanmen waterworks （at city level） was only 109.64±2.97. The analysis also revealed that the genotoxicity of town＇s water sources was higher than that of the city. The results demonstrated that the comet assay can be successfully applied to the genotoxicity monitoring programs of drinking water sources.

Alzheimer's disease(AD) is a devastating neurodegenerative disease that affects ～50 million people globally. The accumulation of amyloid-β(Aβ) plaques, a predominant pathological feature of AD, plays a crucial role in AD pathogenesis. In this respect, Aβ has been regarded as a highly promising therapeutic target for AD treatment. Polyoxometalates(POMs) are a novel class of metallodrugs being developed as modulators of Aβ aggregation, owing to their negative charge, polarity, and three-dimensional *** traditional discrete inorganic complexes, POMs contain tens to hundreds of metal atoms,showcasing remarkable tunability and diversity in nuclearities, sizes, and shapes. The easily adjustable and structurally variable nature of POMs allows for their favorable interactions with Aβ. This mini-review presents a balanced overview of recent progress in using POMs to mitigate amyloidosis. Clear correlations between anti-amyloid activities and structural features of POMs are also elaborated in detail. Finally, we discuss the current challenges and future prospects of POMs in combating AD.

整合酶抑制剂(integrase inhibitors,INSTIs)是治疗人类免疫缺陷病毒(human immunodeficiency virus,HIV)感染者的最新一类药物。自2007年以来,已经有5种INSTIs上市:拉替拉韦(Raltegravir,RAL)、艾维雷韦(Elvitegravir,EVG)、多替拉韦(Dolutegravir,DTG)、比克替拉韦(Bictegravir,BIC)和卡博特韦(Cabotegravir,CAB),这些药物均获得美国食品药品监督管理局(Food and Drug Administration,FDA)批准用于HIV感染者的起始抗逆转录病毒治疗(antiretroviral therapy,ART)。与其他类型抗病毒药物相比,INSTIs具有更好的疗效性及耐受性,因此全球众多国家把包含INSTIs的治疗方案列为HIV抗病毒治疗的优选方案。近年来,随着INSTIs的广泛使用,一些研究数据表明,INSTIs可能存在一些不良反应,比如出现中枢神经系统症状、血脂代谢异常、体重增加、肝肾功能异常等。本综述总结了目前用于成人HIV感染者的INSTIs,强调了5种INSTIs的临床疗效及其不良反应。
