A novel mutation-L539fs/47 of hERG in a Chinese long QT syndrome family

Objective To identify the mutation of human ether-a-go-go-related gene (hERG) and analyze the clinical characteristics of a Chinese family with long ST syndrome (LQTS). Methods The electrocardiogram and DNA samples were obtained from a Chinese LQTS family of 26 members. Genotype was performed with polymorphic short tandem repeat (STR) markers at the known LQT1, LQT2, and LQT3 loci. SSCP analysis was used to find aberrant conformers. hERG mutation was confirmed by cloning and sequencing. Results Three gene carriers were linked to chromosome 7q35-36, where the potassium channel gene hERG was encoded. A 19-base pair deletion was identified. The mutation was located at nucleotide position 1 619-1 637 between transmembrane domains S4 and S5. Furthermore, A1692G polymorphism was found both in the normal control and patients. Conclusion A novel 19 bp deletion mutation of hERG is identified in a Chinese family. All gene carriers are demonstrated to be typical LQT2 ECG phenotype.     

Vacuum-compression therapy for ischemic disease of the extremities：experience with 40 patients

Objective To study the clinical effects of vacuum-compression therapy for ischemic disease of the extremities. Methods A total of 40 cases of peripheral arterial disorders, including 23 thromboangiitis obliterans (31 limbs) and 17 arteriosclerosis obliterans (23 limit), were treated by a self-made vacuum-compression therapeutic apparatus. Results The effective rate in thromboangiltis obliterans and arteriosclerosis obliterans groups was 96.77% and 92.23%, respectively. The cuffs on the apparatus were improved to eliminate discomfort in the patients during treatment. "Rebound symptom" was observed during treatment, which had not been reported previously. Conclusion Vacuum-compression therapy has a good prospect for treating ischemia of the extremities.     

非特殊型浸润性乳腺癌临床病理及同侧腋窝淋巴结转移与Ki-67表达的相关性分析

目的 探讨非特殊型浸润性乳腺癌(IBC-NST)临床病理特征以及同侧腋窝淋巴结转移与Ki-67表达的关系。方法 回顾性收集经病理证实的IBC-NST患者101例,分为Ki-67高表达(70例)和Ki-67低表达(31例)两组。患者临床病理特征等计数资料的组间比较采用χ²检验方法及Kruskal-Wallis H检验方法,超声诊断同侧腋窝淋巴结转移与病理结果的比较采用灵敏度、特异度等相关值计算,同侧腋窝淋巴结转移与Ki-67表达的相关性研究采用Spearman相关分析。结果 不同的Ki-67表达分组中,肿块直径大小、乳腺癌组织学分级及临床分期情况在Ki-67表达组之间差异具有统计学意义(P<0.05),肿块直经≥2 cm(58.57%)、组织学分级Ⅲ级(32.86%)、临床分期Ⅲ期(34.29%)及Ⅳ期(5.71%)的表达阳性率在Ki-67高表达组中较高;同侧腋窝淋巴结转移与Ki-67高表达呈正相关(r=0.393,P<0.05)。结论 IBC-NST病例中,肿块直经≥2 cm、组织学分级Ⅲ级、临床分期Ⅲ期及Ⅳ期与Ki-67高表达有相关性,患者同侧腋窝淋...     

MMP-9及glypican-3在肝癌组织中的表达及其临床病理价值

目的探究基质金属蛋白酶-9(MMP-9)和磷脂酰肌醇蛋白聚糖-3(glypican-3)在肝癌组织中的表达及临床病理价值。方法选取2014年3月至2016年7月于福建医科大学附属第一医院经病理学诊断为原发性肝癌的患者97例为肝癌组,60例健康志愿者入选对照组。免疫组织化学法检测所有研究对象的肝组织取材标本的MMP-9及glypican-3表达,并分析表达变化与肝癌临床特征间的关系。结果肝癌组的MMP-9阳性率和表达评分分别为47.42%、(1.95±1.61)分,远远大于对照组的0(P<0.05)。肝癌组的glypican-3阳性率和表达评分分别为59.79%、(2.21±1.71)分,明显高于对照组的8.33%、(0.83±1.23)分(P<0.05)。肝癌组的MMP-9及glypican-3表达与性别、年龄、肿瘤直径、肝癌分化情况、有无肝癌癌栓,不具有统计学相关性(P>0.05)。结论 MMP-9可用做为肝癌患者早期检测指标,glypican-3在肝癌组织中高表达也有一定的检测意义。     

脑梗塞的磁共振成像与临床

本文讨论了80例脑梗塞磁共振成像与临床表现,其中20例有CT检查。多数病例磁共振成像显示为多发性脑梗塞(95%)。梗塞灶在T_1加权是低信号改变;T_2加权呈高信号改变,急性和慢性期特点一致。资料结果表明:磁共振成像定位准确(98.75%)。病灶检出T_2比T_1敏感,磁共振成像检出病灶多于CT。在诊断脑梗塞方面,磁共振成像优于CT。     

发挥医院图书馆在临床信息需求中的作用

医院图书馆作为医疗、教学和科研服务的文献中心,其中心工作必须与医院的发展同步,其根本宗旨是为临床医疗、科研、教学提供优质有效服务,利用多种方法和手段将图书信息传递到临床,尽最大限度地满足临床对医学信息的需求,实现其应有的价值。因此,医院图书馆应从分析临床需求入手,针对医院图书信息需求随机性强、时效性强、信息量大、以期刊信息为主等特点,尽最大限度地为临床对医学信息的需求提供服务。     

西安地区12年间胃镜检出上消化道癌症分析

目的探讨西安地区内镜检出并经病理证实的上消化道癌症的临床流行病学特点。方法选择1991年1月至2002年12月于西安市三所大型医院进行胃镜检查并经病理确诊的上消化道癌症患者,对其临床、病理、内镜及流行病学特征进行分析。结果12年来上消化道癌症总检出率为8.13%,其中食管癌检出率3.42%,贲门癌检出率1.44%,非贲门部胃癌检出率3.26%,十二指肠癌检出率0.01%。12年来食管癌和胃癌的检出率虽有一些波动,但呈明显下降趋势(P=0.000),贲门癌呈现出较为平缓的上升趋势(P=0.000)。贲门癌的男女性别比为6.29∶1,远较胃癌和食管癌为高(2.92∶1和3.09∶1,P=0.000)。食管鳞癌和腺癌构成无明显变化(P=0.562),食管腺癌没有明显的升高趋势(P=0.557)。结论西安地区食管癌居上消化道癌症之首;12年来胃癌、食管癌的检出率明显下降,贲门癌的检出率呈明显升高趋势;贲门癌为不同于食管癌和胃癌的独立疾病。
