简介:目的研究GOLPH3在胶质瘤组织中的表达及其临床意义.方法选取山东大学齐鲁医院和聊城市脑科医院神经外科自2008年7月至2009年12月间手术切除并经病理证实的人脑胶质瘤标本76例,其中Ⅰ级13例,Ⅱ27级例,Ⅲ级25例,胶质母细胞瘤11例.另取9例因脑创伤行内减压术患者的正常脑组织标本作为对照.应用RT-PCR、Westernblotting分别检测各标本中GOLPH3mRNA和GOLPH3蛋白的表达.结果RT-PCR与Westernblotting检测结果显示正常脑组织中GOLPH3mRNA和GOLPH3蛋白不表达,不同级别胶质瘤组织GOLPH3mRNA、GOLPH3蛋白的阳性表达率差异无统计学意义(P>0.05),而其表达值差异有统计学意义(P<0.05),且随着肿瘤病理级别的增高,胶质瘤组织中GOLPH3mRNA、GOLPH3蛋白表达值增高,差异有统计学意义(P<0.05).相关性检验显示GOLPH3蛋白的表达值与肿瘤的病理分级呈正相关(rs=0.961,P=0.000).结论GOLPH3在不同级别的胶质瘤组织中均有表达,其表达值与肿瘤的病理分级呈正相关,可能是胶质瘤发生发展的重要机制之一.

简介:1病例介绍患者,女,45岁,农民,小学文化。因夜眠差、心烦、自觉浑身不适2年余前来就诊。家族史、个人史无特殊记载,无重大疾病史。2病例分析2.12年前患者无明显诱因出现夜眠差、心烦。逐渐出现浑身不适症状。经常感觉心慌、气短,身体有时忽冷忽热,大小便不规律,经常尿频、尿急,便秘与腹泻交替出现。患者曾就诊于多家医院,做各种检查均未见异常。在综合医院的.医生建议下来我院门诊就诊。查体及各项辅助检查未见异常。精神检查:意识清、问答切题、言流畅、主动述说病情,称因经常感觉浑身不适,心烦、感觉活着没意思。因在多家医院都查不出患什么病,自己对治疗已没有信心,但仍希望医生给好好治疗。注意力、记忆力,智能无异常,白知力部分存在。诊断:躯体化障碍。
