电镜下的乙型肝炎表面抗原

本文对81例乙型肝炎病人的肝活检组织进行了电镜观察,发现HBsAg的阳性率达93.8％。电镜下,HBsAg细丝不仅有一般的管状细丝型,还有分枝管型和管泡型,而且CAH病人肝组织不易找到HBsAg丝(易见者仅9％),CPH,CLH则多数(79.5％)为易见及可见,二者有高度显著性差异(P<0.01)。

虎眼万年青镇痛抗炎作用的实验研究

目的:研究虎眼万年青乙醇提取物镇痛、抗炎作用.方法:采用小鼠热板法和扭体法镇痛实验,观察虎眼万年青提取物的镇痛作用;采用二甲苯致小鼠耳廓肿胀法和醋酸致小鼠毛细血管通透性增高法观察其抗炎作用.结果:虎眼万年青提取物能物能明显延长小鼠的疼痛阈值,降低毛细血管通透性,抑制由二甲苯所致的炎症反应,可显著减轻小鼠耳廓肿胀.结论:虎眼万年青乙醇提取物有明显的镇痛、抗炎作用.     

痴呆治疗体会

10多年来,笔者以化痰、祛瘀、补肾为法治疗痴呆,取得了较好疗效,现选录如下。 1 多发性脑梗死致痴呆 案例1:李某,女,62岁,农民,1994年6月4日初诊。半年前因患多发性脑梗死,经治疗肢体功能恢复正常。但表情呆滞,两目无神,沉默不语,失认失算,不思饮食,秽洁不分,动作呆板,面色晦黯无泽,舌质黯有瘀点,苔白,脉弦细。头部CT示:①多发性脑梗死;②脑萎缩。辨证为血瘀气滞,脑脉不通,元神失养。治以活血化瘀、理气通脉,佐以补肾。药用:当归、川芎各12g,丹参20g,郁金15g,石菖蒲12g,远志、红花、天麻各10g,半夏12g,枸杞子15g,何首乌20g,珍珠粉3g(…     

牙根发育不良疾病的研究进展

牙根发育不良疾病是牙齿根部生理性发育出现障碍的疾病。其发病率为1%~10%,乳、恒牙列均可发生,其结果可导致牙根缺如或短根,严重者可造成牙齿过早脱落。国外学者将该疾病统称为短根异常疾病。其发病因素有遗传性疾病、全身性疾病、外源性因素和医源性因素等。     

低压状态下猪鼾症模型的建立及其CT研究

目的探讨低压环境对动物上气道软组织形态学的影响。方法将试验猪置于一个低压环境饲养6个月建立猪的鼾症模型,当出现类似鼾症临床症状和鼾症相似的咽腔压力波形时,再进行CT扫描影像学检查。并与正常状态饲养的对照组进行对比。结果模型猪咽后壁及软腭明显增厚,分别为(0.94±0.16)cm和(1.06±0.23)cm;对照组分别为(0.60±0.11)cm和(0.59±0.13)cm。模型猪的气管截面积在在前、中、后部分别为(1.49±0.12)cm2、(1.37±0.32)cm2和(1.00±0.21)cm2,其中以悬雍垂水平(后部)最为狭窄;对照组前、中、后部分别为(1.30±0.14)cm2、(1.57±0.32)cm2和(2.48±0.42)cm2。结论低压状态是鼾症的重要的致病因素之一,低压状态可建立鼾症的动物模型。     

肾功能损伤分级系统在成人心脏术后的应用

Objective The aim of this study was to evaluate of adilty of two acute renal failure-specific scoring systenms (the classification by Bellome et al and the AKIN criteria) for predicting hospital mortality after cardiac surgery in adult patients. Methods Between October 1 st 2006 to Decemjber 31 st 2006, 509 adult patients who ungerwent coronary artery bypass grafting (CABG) and/ or valve operation were enrolled in this study. The medical data collection included gender, age, types of operation, perioperative he- modynamic parameters, urine output, biochemical parameters and outcome. Renal function was assessed daily according to the classi- ficatinn by Bellomo and the AKIN criteria, respectively. As references, Acure Physiology and Chronic Health Evaluation(APACHE) Ⅱ and Sepsis-related Organ Failure Assessment (SOFA) score were also calculated. Resuits Three hundred and forty-one patients were male (67.0%), and 168 were female (33.0%), mean age was (56.2±12.0) years old. Tnree hundred and nine patieats un- derwent CABG, 182 underwent valve operation and 18 underwent CABG plus valve operation, Mean duration of ventilation support was (20.4±17.7) houra, and the ICU stay was (1.4±1.0) days. Postoperative hospital stay was (13.8±9.1) days. According to the classification by Bellomo., the highest in-hospital mortality was 52.9% in ARFS group. Mahiplicatinn of in-hospital morality rate was abserved (X2 for trend, P<0.01) in 0.4% (non-ARF), 1.2% (stage 1), 12.0% (stal～ 2) and 32.4% (stage 3) of pa- tients based on the AKIN criteria. By applying the area under the receiver operating characteristic ourve, the classification by Bellomo and the AKIN criteria had good discriminative power. Furthering, multivariate logistic regression analysis verified that the Odds Ratio of the AKIN criteria was 5.478 (P =0.028, 95% Confidence Interval 1.027- 24.856), after adjusting for gender and age. Con- clusion Analytical data confinned good discriminative power of both the AKIN criteria and the classification by Bellomo for predicting hospital mortality of adult postoperative patient with ARF.
