体外构建的皮肤模型InspectskinⅠ修复裸鼠全层皮肤缺损
Zhongshan Daxue xuebao. Yixue kexue ban, 2009 【目的】 探讨胚胎来源表皮干细胞构建的人工皮肤模型InspectskinⅠ修复全层皮肤缺损的作用,为构建含皮肤附属结构的检验用皮肤奠定基础65377; 【方法】 将人羊膜和BMP-4定向诱导小鼠胚胎细胞分化为表皮干细胞,采用筏式培养在体外与PHBV和成纤维细胞共培养构建组织工程皮肤,经短暂培养后移植于裸鼠皮肤缺损创面,对移植物进行形态学和免疫组织化学观察65377; 【结果】 移植物可封闭皮肤缺损,在其表面可形成复层表皮样结构,真皮部分可见大小不等的由单层或复层上皮样细胞构成的管状和泡状结构65380 ...

, 2010 通过野外定位观测试验,探讨了黄土区不同植被类型下生物结皮的土壤水分入渗和水土保持效应。分析结果表明:①单纯BSC降低入渗,减幅达8.3%,但入渗效应并非呈单一的增加或减少的表现形式。生物结皮与植被(长芒草和柠条)组合时,入渗增加作用进一步提高,但生物结皮的贡献率明显低于植被,长芒草、柠条下生物结皮的增渗幅度分别为8.5%,0.2%。②雨季初期BSC减少地表径流(减幅约50%),雨季后期径流反而增加。生物结皮同覆盖度较高的长芒草组合时,减流贡献很小,径流调控率<15%,而与覆盖度较低的柠条组合时 ...

热休克蛋白 90 调节内皮一氧化氮合酶 (一个新近认识的心血管疾病调节物 9)
Zhongshan Daxue xuebao. Yixue kexue ban, 2004 阐述热休克蛋白90(hsp90)作为一个心血管疾病新的调节物,在调节内皮一氧化氮合酶(eNOS)功能方面的作用:血管内皮一氧化氮(NO)主要来源于eNOS;eNOS同时有产生NO和氧阴离子自由基()的功能。NO与的平衡在调节心血管方面有着重要的作用,当这个平衡被打破时可导致多种心血管疾病的发生发展;实验发现,当hsp90与eNOS结合增加时,eNOS耦联产生NO,当hsp90与eNOS结合减少或结合后无发生结构改变时eNOS非耦联产生。进而提出深入探讨hsp90调节eNOS机制的必要性。
