目的获取成都中医药大学与南京中医药大学在校大学生的视频显示终端综合征(VDTS)的现状及其影响因素。方法在两所中医药高校内发放自行设计的问卷。运用二元Logistic回归模型分析VDTS发生的影响因素。结果两所学校共发放问卷240份,回收有效问卷122份,发生VDTS 85例。VDTS导致的不适症状中,眼部症状(97.54%)最常见,眼干、眼红、颈肩疼痛检出率女生(86.00%,64.00%,87.00%)均高于男生(68.18%,36.36%,68.18%)(P值均<0.05)。二元Logistic回归模型分析显示女性、饮酒史、屈光不正、VDT过度使用、晚睡、睡眠不足均可能增加被调查者患VDTS的风险。结论研究群体中VDTS发生率69.67%,女性、饮酒史、屈光不正、VDT过度使用、晚睡、睡眠不足均会影响VDTS的发生。

汤剂传承千年,是中医临床应用最广的一种剂型,也是中医辨证论治的核心手段之一。但汤剂煎煮方法与临床疗效紧密相关,影响煎煮效果因素众多,且中药各有性质,煎煮亦有不同,故中药煎煮常缺乏规范性,掌握正确的煎煮方法,明了煎药影响因素,洞悉中药处方特点,对中药进入人体发挥作用至关重要。中医眼科发展了中药煎剂的应用范围,雾化方式的应用,丰富了汤剂的给药途径,唯有明确煎药法理,方能更好指导眼科临床应用。

易地扶贫搬迁是全国各地打赢脱贫攻坚战的关键举措。从贵州省安置区政策实践来看,安置区群众基本解决了“两不愁、三保障”问题,但安置区老年人养老保障问题日益突出。基于阿玛蒂亚·森的可行能力理论,运用模糊数学方法,从经济保障、健康保障、生活照料保障、精神慰藉保障4个维度对安置区老年人养老保障水平进行测算分析,发现总体保障水平相对合格,但是老年人社会融入、生活照料、健康支出、工作情况等方面的问题突出。应该以实现安置区老年人经济及健康保障有安全感、生活照料保障有获得感、精神慰藉保障有幸福感为理念,厘清安置区老年人养老保障供给原则和路径,构建易地扶贫搬迁安置区老年人养老保障供给框架,以期不断提高安置区老年人养老保障水平。

文章建立了宏观经济传导模型和信贷风险传导模型,根据对GDP的估计,对新型冠状病毒感染肺炎疫情下的2020年全国和若干疫情严重省市的不良贷款率进行了定量测算.假设一季度内疫情得以控制,全年GDP增速下降至5.7%的情景下,预计全国年末不良贷款率约3%,不良贷款余额比2019年增加逾80%,接近2019年国内商业银行贷款损失准备金余额.如果疫情持续半年,全年GDP增速下降至5.45%的情景下,预计全国不良贷款率将达到3.37%,不良贷款余额比2019年增加逾100%,超过2019年国内商业银行贷款损失准备金余额.疫情带来巨大的潜在不良贷款增量,可能导致抗冲击能力较弱的银行出现重大信用风险.
