尿蛋白-1与糖尿病肾病关系的研究

目的为了探讨尿蛋白-1(UP-)与糖尿病肾病的关系。方法用酶联免疫法测定了90例非胰岛素依赖型糖尿病(NIDDM)患者的UP-1,同时测定尿N-乙酰-β-D-氨基葡萄糖苷酶(NAG)、β2-微球蛋白(β2-mG)。结果糖尿病患者UP-1均较正常对照组增高,UP-1与尿A1b、尿NAG和β2-mG呈正相关。结论在糖尿病早期阶段,肾小管会受到损害,UP-1可作为诊断早期糖尿病肾病的敏感指标。     

三吡萘啶对伯氏疟原虫ANKA株超微结构的影响

受染伯氏疟原虫ＡＮＫＡ株小鼠ｉｇ三吡萘啶游离碱１１ｍｇ／ｋｇ给药后１ｈ可见少数滋养体复合物层次增多且断裂，皱缩，并出现间隙，食物泡融合增大，２ｈ后进一步加剧，且疟原虫髓样物也增多，线粒体肿胀，４ｈ后出现变化的原虫更明显增多，８ｈ后绝大多数滋养体结构多已瓦解，仅留上膜残体及大小不等的空泡，总之，其超微结构的变化与咯萘啶作用甚为相似。

肝动脉化疗,栓塞与肝静脉暂时闭塞治疗肝癌

本文报道在10例肝癌患者中运用肝静脉暂时闭塞和肝动脉内灌注化疗、栓塞的方法治疗取得较好疗效。7例甲胎蛋白阳性患者5例下降大于50%,2例转阴。4例肿瘤缩小>50%。2例合并肝动-静脉瘘者成功实行碘油栓塞,1例经治疗后肝动-静脉瘘消失。对肝功能的影响与普通介入治疗相同。消化道反应相对较轻。并可提高肿瘤局部药物浓度,延长药物作用时间。配合肝段动脉或靶血管的插管可进一步提高疗效,减少并发症。     

Synergistic renal protection by combining alkaline-diuresis with lipid peroxidation inhibitors in rhabdomyolysis: possible interaction between oxidant and non-oxidant mechanisms

BACKGROUND AND PURPOSE.: Heme-proteins, besides causing renal tubular obstruction, maycontribute to rhabdomyolysis-induced renal injury through aheme-iron-mediated lipid peroxidation process. In the presentstudy, we compared the combined therapy of a lipid peroxidationinhibitor, 21-aminosteroid (21-AS) and fluid-alkaline-mannitol(FAM) diuresis with either of them alone to determine the efficacyof the combination therapy and to delineate the roles of lipidperoxidation and cast formation. METHODS AND RESULTS.: Employing Raman spectroscopy, we confirmed in vitro the abilityof 21-AS to inhibit iron-induced fatty acid peroxidation. 21-ASwas then administered to rats developing renal failure fromglycerol-induced rhabdomyolysis. Although 21-AS inhibited rhabdomyolysis-inducedplasma and renal lipid peroxidation, renal protection was incomplete.Administration of FAM to inhibit cast formation afforded a betterrenal protection. However, when these therapies were combinedto inhibit both lipid peroxidation and cast formation, therewas a synergistic renal functional protection. This was accompaniedby a maximum inhibition of renal and plasma lipid peroxidation,as well as, renal tubular necrosis and cast formation. Comparedto combination therapy, FAM therapy alone, despite identicalvolume, was accompanied by a higher tubular necrosis and castformation. CONCLUSIONS.: That combining a lipid peroxidation inhibitor with fluid-alkalinediuresis in rhabdomyolysis further lowers renal lipid peroxidation,tubular necrosis and cast formation and synergistically limitsrenal dysfunction (i) supports a role for lipid peroxidationin the pathophysiology of rhabdomyolysis ARF, (ii) underscoresthe role of intratubular heme retention, a cause for tubularobstruction as well a source for prodigious amount of iron,likely involved in the lipid peroxidation, and (iii) raisesthe possibility of interactions between non-oxidant and oxidantmechanisms.     

中国农村地区5岁以下儿童肺炎死亡社会危险因素研究

目的 调查农村5岁以下儿童肺炎死亡相关的社会危险因素.方法1995年11月—1997年2月在湖北恩施和建始两个贫困地区对5岁以下儿童肺炎死亡的危险因素进行病例—对照研究,死亡病例组226例,肺炎对照组 452例.结果 引起儿童肺炎死亡的社会-经济危险因素有:家庭的人均年收入少于 450元、母亲没有立即带孩子看病的理由是没钱看病或交通不便、家中曾有过一个孩子死亡、家长和村医生的文化程度低、父亲的职业是农民、居室内有火炉、母亲对疾病的认识不够、医生的专业培训不足等.结论 除生物相关因素外,社会危险因素同样是农村5岁以下儿童肺炎死亡的重要因素.它们中某些因素是可以借助对父母的健康教育和急性呼吸道感染病例标准管理而得到控制.     

垂体腺瘤的CT诊断(附60例分析)

分析了60例垂体腺瘤的CT表现。1例垂体微腺瘤缺乏特异性征象,59例大腺瘤大多数表现典型,诊断依据为肿瘤位置和蝶鞍改变。垂体腺瘤的形态学表现无特异性。应加强对垂体瘤卒中和侵袭征象的认识。对成人鞍区肿瘤的鉴别诊断进行了简短讨论。     

THE COMPUTERIZED GAIT ANALYSIS SYSTEM AND THREE DIMENSIONAL ANALYSIS OF FOOT-GROUND REACTION FORCES DURING LEVEL WALKING

A S9-2 computerized gait analysis system developed by us is reported. The advantages of the system are: synchronous measurement of the forces, angles and time parameters; high efficiency, accuracy and good repeatability; low cost and easy to operate. A three dimensional analysis of the foot-ground reaction forces of 41 normal subjects during level walking was carried out by the S9-2 system and a series of normal values of parameters and characteristic curves were obtained. The mechanism of formation of the parameters and curves and the sex influence were investigated and discussed. In old subject, before the development of "cautious gait", most values of the parameters did not differ significantly from those of the young subjects, except that the centre of gravity of the body crossing the hip earlier with a slight decrease in the medio-lateral balance capacity.
