Clinical and familial study of arrhythmogenic right ventricular cardiomyopathy

Objective　To explore the characteristics of arrhythmogenic right ventricular cardiomyopathy (ARVC). Methods　Seven patients with arrhythmogenic right ventricular cardiomyopathy and 34 members of three families were studied. All patients and family members underwent history collection, clinical examination, electrocardiogram (ECG), two-dimensional echocardiography (2-DE) and a signal averaging electrocardiogram. Programmed ventricular stimulation was performed in five patients. Results　All patients and family members had normal morphologic characteristics and normal function of the left ventricular by 2-DE. Fourteen persons had abnormal findings indicating ARVC. Five had enlargement of the right ventricular with diffused hypocontractility, eight had thin and systolic bulging in the focal anterior wall with hypokinesia and one had bulging of the inferior wall. Twenty-five persons (seven patients and 18 family members) had abnormal findings in ECG. Positive ventricular late potential was recorded in 13 persons (six patients). Two to three monomorphic ventricular tachycardia (VT) with left bundle branch block (LBBB) configurations were induced in five patients. Ventricular fibrillation was induced in two patients during the electrophysiologic study (EPS). Five patients had very high pacing threshold and/or ineffective pacing in one or many regions of the right ventricle. Two members of one family died suddenly. One member was a dwarf with ARVC. Spontaneous VT with a left bundle branch block (LBBB) configuration was recorded in five patients, polymorphic VT with extremely short coupling interval in one, and premature ventricular complexes with LBBB configuration in 12 (six patients). Conclusion　Our familial study strongly suggests that ARVC may be a hereditary disease and it is helpful in the diagnosis and detection of ARVC. The most common manifestations were abnormal structure and function of the right ventricle and abnormal ECG of repolarization and ventricular arrhythmia which originates from the right ventricle.

医学微生物学二段式教学改革

我们将医学微生物学教学改为二个阶段进行 ,第一阶段 :基础医学微生物学教学 ,安排在基础课后期进行 ,主要讲授医学微生物学的基础理论和基础知识。第二阶段教学为临床微生物学 ,安排在临床教学中后期 ,由微生物学教研室、传染科、内科、检验科等联合主办。即解决与临床脱节问题 ,又通过多学科联合教学解决各学科之间内容的衔接问题     

HCVⅡ型病毒在EBV转化人PBMC中持续存在的研究

近年来发现丙型肝炎病毒(ＨＣＶ)不仅可以感染肝细胞,也可以侵入肝外多种组织和器官,尤其其嗜淋巴细胞性正在引起越来越多的关注。已有研究证明,丙型肝炎病人外周血单个核细胞(ＰＢＭＣ)中既有ＨＣＶＲＮＡ正链存在,也有负链存在,表明ＨＣＶ可在ＰＢＭＣ中复制。ＰＢＭＣ?..     

红要子烧伤酊的毒理作用及临床应用

目的:探讨中药制剂红要子烧伤酊的毒理作用,评价其临床效果及应用前景.方法:烧伤面积1%～20%Ⅱ度伤为主的烧伤患者40例,外用烧伤酊与磺胺嘧啶银(SD-Ag)作对照,观察用药反应,愈合时间.同时选择豚鼠及家兔分别进行烧伤酊的皮肤急性毒性试验,皮肤长期毒性试验,皮肤刺激试验及皮肤过敏试验.结果:烧伤酊组与SD-Ag组治疗Ⅱ度烧伤有效率均达100%.在创面反应、愈合时间上统计学处理差异无显著性(P＞0.05).毒理实验结果表明烧伤酊对皮肤仅有轻微的刺激反应及过敏反应.结论:红要子烧伤酊是一种副作用小、使用安全可靠的中药类烧伤创面外用药,值得进一步推广应用.
