雷公藤多苷治疗儿童肾病综合征的机制探讨

目的 :探讨雷公藤多苷在治疗儿童肾病综合征中的作用及其机制。　方法 :对 16年来在我科住院明确病理类型的 5 5 0例中 10 5例肾病综合征患儿 ,在激素逐渐减量的同时用雷公藤多苷 ( 1m g/ kg· d- 1 )治疗。　结果 :81例肾病综合征获得缓解 ,总缓解率达 77.1% ,其中 MCNS( 2 4例 )、Ms PGN ( 46例 )、MPGN ( 17例 )、MN ( 13例 )和FSGS( 5例 )的缓解率分别为 91.7%、89.1%、76 .5 %、38.5 %和 0 % ,FSGS效果最差 ;14例改善 ,10例无效。　结论 :由于病理类型不同疗效相差较大 ,临床上对激素治疗无效或耐药的肾病综合征患儿 ,应及时行肾活检以明确病理诊断 ,对病理类型为 MCNS和 Ms PGN者可单用雷公藤多苷治疗 ,以避免长期应用激素的不良反应 ,这是治疗儿童肾病综合征的有效方法之一     

电化学聚合漆酚-锌金属螯合物合成及性质研究

以电化学方法合成了聚合漆酚（ＥＰＵ）,并用ＥＰＵ与二异丙氧基锌作用生成漆酚金属螯合物「ＥＰＵ－Ｚｎ（Ⅱ）」,采用原子发射光谱（ＡＥＳ）、ＦＴ－ＩＲ、ＤＭＴＡ、ＴＧ－ＤＴＡ和ＸＰＳ等对其进行表征,探讨其结构与性质。证明了螯合物中存在着因Ｚｎ（Ⅱ）和ＥＰＵ配位作用而引起的交联,故难溶于绝大多数的有机溶剂,玻璃化转变温度和耐热性能的提高。

Undifferentiated carcinoma with osteoclast-like giant cells of the pancreas diagnosed by endoscopic ultrasonography-guided fine-needle aspiration

Undifferentiated carcinoma with osteoclast-like giant cells, also formerly known as osteoclast-like giantcell tumor, is a rare neoplasm of the pancreas and usually diagnosed after pancreatectomy. The presence of non-neoplastic osteoclast-like giant cells is the histological hallmark of this tumor and the diagnosis is usually not difficult on tissue sections. However there have been relatively few reports regarding the cytological features of this type of tumor in literatures.1-4 Here we.     

一氧化氮内皮素-1与早期糖尿病肾病及中医药防治

近年发现一氧化氮(NO)和内皮素-1(ET-1)很可能构成一对具有拮抗作用的血管活性物质,在糖尿病肾病1期肾小球高滤过中起重要的调控作用。而中药对糖尿病早期异常肾血流动力学的改善作用的研究报告很少,且目前有关研究似显肤浅。     

n-Hexane neuropathy caused by addictive inhalation: clinical and electrophysiological features

To assess the clinical and electrophysiological features of n-hexane neuropathy caused by addictive inhalation, 4 patients were studied in the progressive phase. The neurological manifestations were characterized by subacute predominantly motor polyneuropathy and disease progression despite discontinuance of the chemicals, which were similar to those reported in industrial exposure, although with a severer degree associated with anorexia and body weight loss. Electrophysiological studies showed that all showed multifocal conduction block and profound conduction slowing, as well as features of axonal degeneration. Sural nerve biopsy showed axonal loss, axonal swelling, and thin myelin probably due to retraction by axonal swelling. n-Hexane abuse causes severe subacute polyneuropathy. The mixed axonal and demyelinating electrophysiological features were consistent with peculiar pathological findings. Conduction block, probably due to paranodal myelin retraction or ongoing wallerian degeneration, is very frequent and could be responsible for the clinical deficits, especially in the early phase of illness.
