大承气汤加黄连在肛周常见疾病术后的应用体会

我们自2000年10月至2008年12月采用大承气汤加黄连应用与肛周常见疾病术后病人,治疗其术后大小便潴留,里急后重等症状,取得了满意的疗效,现报告如下.     

基于人文理念的护理质量例会实践与体会

建立以人文理念为核心的护理质量分析例会制度，每月召开门诊护士长、护士组长、护士代表例会，分析、讲评门诊护理服务中存在的问题，并提出改进方案，持续改进门诊护理服务质量。     

Targeted Thrombolytic Therapy

Venous and arterial thrombosis are closely related to many severe diseases, especially to cardiovascular and cerebrovasular disorders. Thrombolytic therapy has been proven to be an effective method to treat such disease, which decreased the mortality and morbidity greatly.     

荧光示踪法研究逆行岛状皮瓣静脉回流

目的探讨采用荧光示踪法研究逆行岛状皮瓣静脉回流的可行性，并初步观察静脉回流规律。方法20只新西兰大白兔，每只取耳静脉血0．ImL，分离RBC并用FITC标记。流式细胞仪检测已标记的RBC阳性率及荧光强度，倒置荧光显微镜观察其形态。取20只新西兰大白兔，在动物双侧后肢内侧分别建立4cm×3cm隐动、静脉逆行岛状皮瓣模型（n=10）和顺行岛状皮瓣模型（n=10），血管蒂长3cm。将一侧后肢随机设定为实验组，皮瓣制备后注射已标记的RBC悬液5pL；对侧为对照组，不注射示踪剂。实验组按顺行和逆行皮瓣分成两组，即顺行皮瓣组和逆行皮瓣组，每组10个；再根据注入示踪剂途径不同，分为动脉和静脉2个亚组，每亚组5个皮瓣。注射示踪剂5S后取下皮瓣立即冷冻，取连续的3张冰冻切片（5～7pm），其中2张行HE染色和GENMED染色，另]张不染色直接压片，荧光显微镜观察荧光分布。结果流式细胞仪分析FITC标记的RBC阳性率在99％以上，荧光强度均≥10。；倒置荧光显微镜下标记的RBC呈均匀分布的绿色荧光，荧光强度均匀、稳定。冰冻切片显示实验组皮瓣蒂部均出现荧光，对照组未见荧光。顺行岛状皮瓣组荧光主要分布在静脉腔、静脉壁、动脉内膜和外膜；逆行岛状皮瓣组荧光分布在动脉内膜、外膜和静脉壁。结论荧光示踪剂可用于静脉回流研究，顺行岛状皮瓣静脉主要通过静脉腔、静脉壁、动脉内膜和外膜回流；逆行岛状皮瓣静脉主要通过动脉内膜、外膜和静脉壁的“迷宫式途径”回流。     

弥漫性轴索损伤病人的护理

弥漫性轴索损伤 (DAI) ,在脑损伤中发生率高 ,病死率高 ,占脑外伤死亡病人总数的 3 5 %。全部DAI病人中植物生存率为 15 % ,重残 14 % [1] 。为了降低病死率 ,提高病人的生存质量 ,现将 1999年 1月— 2 0 0 2年 1月我院收治的 5 5例DAI昏迷病人的护理体会总结如下。1　临床资料　　本组 5 5例 ,男 3 8例 ,女 17例 ,年龄 6岁～ 68岁 ,平均 40 .9岁。格拉斯哥 (GLS)计分均 <8分 ,其中评分为 3分～ 5分的特重型病人 3 2例。致伤原因 :车祸 44例 ,高处坠落 8例 ,打击伤 3例。 5 5例病人中有 17例因合并颅内血肿而行开颅手术 ,其他病人为保…     

Synthesis and Purine P2X Receptor Antagonist Activity of Thiazole Derivatives

The ability of 12 new thiazole derivatives to influence the muscle contractility mediated by purine P2X receptors has been studied in vitro using isolated tissues of rats and guinea pigs. Most of the synthesized compounds did not cause significant effects, but two compounds exhibited pronounced antagonism with respect to P2X-mediated contractility response. These compounds offer a good starting point for the synthesis of new effective antagonists of P2 receptors. __________ Translated from Khimiko-Farmatsevticheskii Zhurnal, Vol. 39, No. 6, pp. 22 – 25, June, 2005.     

Effect of kanamycin on the cochleas in guinea pigs

Kanamycin (400 mg/kg) was injected daily for 5 days in guinea pigs, the changes in CM and AP responses were recorded. The CM threshold was elevated in 34.5% of the animals and the CM amplitude was reduced when compared with normal animals (P less than 0.005). The AP threshold was elevated in 13.8%. The latency of N1 was increased (P less than 0.001) and the amplitude of N1 reduced at 80 dB (S-L) (P less than 0.001).cAMP and cGMP levels in the organ of Corti and stria vascularis spiral ligament decreased, and the decrease correlated with the changes in auditory function. We consider the reduction of cyclic nucleotides in the cochlea may be important in kanamycin ototoxicity.
