简介：摘要目的研究“集中培训+交流合作+自主发展”干预模式在预防糖尿病足中的应用效果。方法选择158例2型糖尿病合并糖尿病高危足患者为研究对象，随机分为观察组和对照组各79例，对照组实施糖尿病常规护理，观察组施行“集中培训+交流合作+自主发展”的干预模式。结果观察组在遵医用药、足部护理、血糖监测、饮食控制、加强运动各维度得分、糖尿病足知识及足部自我护理优良率均高于对照组，糖尿病足发生率(1.27%)明显低于对照组(8.86%)（P<0.05）。结论“集中培训+交流合作+自主发展”干预模式能提高2型糖尿病患者自我管理水平，有效预防糖尿病足的发生。

简介：目的构建含有人E2F2基因和绿色荧光蛋白基因（pEGFP）的腺病毒载体,为聋病的基因治疗奠定实验基础。方法根据已知的E2F2基因序列设计并合成相应的双链DNA,将其与酶切线性化的pDC315-EGFP载体片段连接,构建穿梭质粒pDC315-GFP-E2F2,并将其与腺病毒骨架质粒pBHGlox△E1,3Cre共转染HEK293细胞,同源重组产生重组腺病毒。对重组腺病毒进行扩增、纯化及滴度测定,用聚合酶链反应和测序方法验证穿梭质粒pDC315-GFP-E2F2穿梭质粒的构建;通过荧光显微镜和Westernblot（蛋白质印迹）方法,分别检测质粒pDC315-GFP-E2F2和重组腺病毒表达E2F2蛋白情况。结果经聚合酶链反应鉴定和测序分析,证实穿梭质粒pDC315-GFP-E2F2与设计一致;经荧光显微镜检测,分别由穿梭质粒pDC315-GFP-E2F2、重组腺病毒转染的HEK293细胞均可观察到GFP表达;经WesternBlot检测出在72kDa～95kDa处有条特征带,其大小和E2F2-GFP融合蛋白（～76kDa）相吻合;滴度测定为1×1011PFU/ml（PFU,plaqueformingunit,空斑形成单位）。结论成功构建了人E2F2基因重组腺病毒载体,并能在HEK293细胞中表达。
