桃红四物汤联合银杏酮酯滴丸治疗老年出血性玻璃体混浊的临床疗效研究

目的:探究桃红四物汤联合银杏酮酯滴丸治疗老年出血性玻璃体混浊的临床疗效。方法:收集2016年12月-2018年12月我院收治的老年出血性玻璃体混浊患者67例,共67眼,根据随机对照表分为对照组和试验组,其中试验组34例,对照组33例,对照组予以银杏酮酯滴丸;试验组在对照组的基础上联用桃红四物汤。两组均服用30 d。治疗结束后对比分析两组患者临床疗效、出血吸收时间、血液流变学及视网膜中央动脉血流动力学。结果:治疗后两组患者高切全血粘度、低切全血粘度、纤维蛋白原、阻力指数(Resistance Index,RI)低于治疗前,收缩期峰值速度(Peak Systolic Velocity,PSV)、舒张末期血流速度(End Diastolic Velocity,EDV)高于治疗前,差异具有统计学意义(P<0.05);治疗后试验组临床总有效率、PSV、EDV高于对照组,出血吸收时间、高切全血粘度、低切全血粘度、纤维蛋白原、RI低于对照组,差异具有统计学意义(P<0.05)。结论:桃红四物汤联合银杏酮酯滴丸治疗老年出血性玻璃体混浊临床疗效显著,适宜临床应用推广。

Effects of Pyridoxalated Hemoglobin Polyoxyethylene Conjugate and Stroma-free Hemoglobin on Renal Vascular Responsiveness to Vasoactive Substances in Isolated Perfused Rat Kidney

Abstract: The effects of pyridoxalated hemoglobin polyoxyethylene conjugate (PHP) and stroma-free hemoglobin (SFH) on vascular responsiveness to various vasoactive substances were examined in isolated perfused rat kidneys. The kidneys isolated from rats were perfused with 6% PHP, 6% SFH, and 6% hydroxyethylstarch (HES) solution at a constant flow rate. Vascular responsiveness to acetylcholine (ACh), nitroglycerin (NG), norepinephrine (NE), and angiotensin-II (ANG-II) was examined by measuring the perfusion pressure (PP). Effects of inhibition of endothelium-derived relaxing factor (EDRF) by N^G-monomethyl L-arginine (L-NMMA) on NE-induced and ANG-II-induced renal vascular responses were examined. ACh and NG induced a dose-dependent decrease in perfusion pressure (PP) in all groups. NE and ANG-II induced an increase in PP in all groups, but NE-induced and ANG-II-induced responses in the PHP-perfused and SFH-perfused groups were significantly larger than those in the HES-perfused group. L-NMMA did not alter vascular responsiveness to NE and ANG-II. These results indicate that PHP and SFH do not inhibit EDRF induced by ACh, but hemoglobin moiety per se does augment the vascular responsiveness to NE and ANG-II in the isolated perfused rat kidney.     

Modified Kalish osteotomy: A simple approach to minimizing proximal dorsal stress risers

Proximal dorsal stress risers are a potential complication to the Kalish osteotomy. The authors describe a modification to this osteotomy that is simple and effective. Since performing the wing-clip modification, there have been no observed stress risers.     

复方保元煎对绝经后CHD患者脂代谢和血流变影响的研究

目的:研究复方保元煎对绝经后冠心病(CHD)患者脂代谢、血流变的影响。方法:观察180例患者,随机分为治疗组102例,对照组78例。治疗组采用中药复方保元煎治疗,对照组采用维尼安治疗,分别于治疗前后测定脂代谢、血流变指标。结果:治疗后两组脂代谢、血流变指标均有不同程度的改变。治疗组在降低总胆固醇(TC)、甘油三酯(TG),低密度脂蛋白(LDL-C)、载脂蛋白B(apoB)、血流变指标优于对照组(P<0.05或P<0.01)。结论:复方保元煎能改变血脂代谢、调节血黏度,对预防和逆转绝经后的CHD的发生和发展有积极的治疗作用。     

中药聪脑汤治疗老年性痴呆的临床研究

目的:比较聪脑汤和双益平(石衫碱甲)片剂治疗老年性痴呆(阿尔茨海默病,Alzheimerdisease,AD)的疗效。方法:35例AD病人随机分为2组,聪脑汤组20例,双益平组15例;分别给予聪脑汤50ml,口服,日3次和双益平片剂0.15mg,口服,日2次,两组疗程均为8w。结果:与治疗前相比,两组长谷川痴呆量表(HDS-R)积分均有显著性改善(P<0.05),聪脑汤组和双益平组总有效率分别为75%和73.4%,两组比较差异无显著性。结论:聪脑汤对AD临床症状有一定改善作用。
