简介：患者女性，51岁。2008年3月在我科接受全身麻醉下左颈部肿物摘除术。术中病理检查证实为左颈部乳头状腺癌淋巴结转移，后行左颈部淋巴结清扫术和甲状腺结节探查术，病理检查未见癌组织。术中分离颈内静脉下段时，可见少量清亮透明液体，但未发现明确漏出点，未予特殊处理。第2天，患者出现轻度呼吸困难，左胸壁肿胀，术区可见少量乳白色液体漏出（见附2页图①）。纤维喉镜检查：左下咽部膨隆，会厌向右侧隆起、肿胀，呈乳白色塑料皮样外观，咽喉部黏膜光滑。喉部及肺部CT扫描：喉旁、颌下、左颈部及左前胸壁弥漫性肿胀，伴左颈部软组织积液，

简介：90D裂隙灯显微镜前置镜是双凸透镜（图1），检查时是利用裂隙灯较强光源，检查时所获的眼底图像立体感好，可以很清楚地显示视盘小凹，血管变异，黄斑裂孔或囊肿，视网膜裂孔，眼内占位等病变，并且由于检查过程中不接触角膜，

简介：目的观察1,25（OH）2D3对高糖诱导牛视网膜血管内皮细胞（BRECs）中血管内皮生长因子（VEGF）的表达水平变化及对细胞凋亡水平的影响。方法将分离培养的BRECs分为三组,分别为正常糖组、高糖组和高糖处理组。正常对照组细胞培养液含5mmol/L葡萄糖,高糖组细胞培养液含30mmol/L葡萄糖,高糖处理组细胞培养液含30mmol/L葡萄糖和50nM,1,25（OH）2D3。培养48h后收集细胞蛋白。蛋白免疫印迹法检测细胞VEGF及细胞凋亡相关蛋白Bax和Bcl-2表达水平;PI/Hoechst双染色法检测细胞凋亡。结果相比于正常糖组,高糖组中VEFG水平和Bax/Bcl-2比值显著增加;而在高糖处理组中表达水平远远低于高糖组,差异均有统计学意义（P〈0.05）。高糖的细胞凋亡水平高于正常糖组,而经过1,25（OH）2D3处理后,其细胞凋亡水平则有所下降,差异均有统计学意义（P〈0.05）。结论1,25（OH）2D3可以抑制高糖诱导BRECs中VEGF表达增加及细胞凋亡。
