简介：目的探讨非小细胞肺癌（NSCLC）组织中醛酮还原酶1C3（AKRlC3）表达及其临床意义。方法收集2013年1月至2016年3月88例手术切除的NSCLC组织及83例癌旁正常组织，采用实时荧光定量PCR（QPCR）法检测上述组织中的AKRlC3表达水平，分析AKRlC3表达与NSCLC临床病理参数（性别、年龄、TNM分期、肿瘤大小、组织学类型及淋巴结转移）的关系；根据随访资料分析AKRlC3表达与预后的关系，采用受试者工作特征曲线（ROC）评价AKRlC3表达在NSCLC早期诊断中的效能。结果NSCLC组AKRlC3表达水平为0．187±0．175，低于癌旁正常组织的1．079±0．384，差异有统计学意义（P〈0．05）；AKRlC3诊断NSCLC的曲线下面积为0．982（95％CI：0．966～0．998）。AKRlC3表达与NSCLC性别、年龄、组织学类型及淋巴结转移无关，与肿瘤大小及TNM分期有关。肿瘤大小〉3em的AKRlC3表达量为0．095＋0．055，低于肿瘤大小≤3em的0．340±0．201，而Ⅲ、Ⅳ期的AKRlC3表达量为0．094±0．058，低于I、Ⅱ期的0．265±0．202，差异有统计学意义（P〈0．05）。全组NSCLC患者的中位总生存期（OS）为17．60个月。AKRlC3高表达者的中位0s为20．60个月，高于低表达者的11．90个月，差异有统计学意义（P〈0．05）；I＋Ⅱ期患者的中位OS为21．65个月，高于Ⅲ＋Ⅳ期的16．20个月，差异有统计学意义（P〈0．05）；肿瘤大小≤3em者的中位OS为18．40个月，高于〉3em者的15．70个月，差异有统计学意义（P〈0．05）。结论AKRlC3在NSCLC组织中表达降低，且与TNM分期、肿瘤大小及预后有关，可能与NSCLC发生发展有关，在NSCLC诊断及病情评估有一定价值。

简介：客观干扰素(IFN)和ribavirin(RBV)的联合是为丙肝的标准治疗病毒(HCV)感染。HCV遗传型2a对治疗证明了更顺从，但是它的功效是还有限的。这研究试图在HCV遗传型2a感染的一种情况中调查差的反应的机制。方法：我们从一个病人分析了HCVRNA的动态变化，与HCV遗传型2a感染了，显示出差的virological回答到是的IFN/RBV判定了12在由HCV的治疗的开始以后的星期克隆定序。然后，我们构造了subgenomic日语有人性化的Gaussia的暴发性的hepatitis-1(JFH1)replicon和不同妄想的replicons酶基因。妄想的replicons从subgenomicJFH1replicon，NS5A区域被病人顺序从pre/posttreatment在代替被导出，并且到IFN的妄想的replicons危险性被相对Gausia酶活动评估。预告的处理HCV定序的结果显得几乎一致，并且quasispecies变化是进一步的在12星期治疗以后简化的更多。而且，quasispecies变化似乎相对，在NS5A更多样化为IFN反应关键的一个区域，和每妄想的replicons展出了不同反应到IFN。结论在长期的感染的功课期间，HCV人口似乎被使适应病人免疫学的系统，并且推进被IFN/RBV治疗的联合选择，显示quasispecies可以完全与IFN的与那些不同的目标由另外的药的增加消除了。另外，到IFN的妄想的replicon的各不同的反应与氨基酸变化在或在在长期的感染和IFN/RBV治疗期间决定NS5A的区域(ISDR)的IFN敏感附近有关是最可能的。

简介：目的人胃癌组织中caspase-3表达的研究。探讨caspase-3表达-9胃癌预后的关系。方法应用免疫组织化学ABC法检测人胃癌组织中caspase-3的表达情况。结果周围正常胃粘膜上皮caspase-3阳性率为94／99（94．9％），胃癌组织中caspase-3的阳性率为62／99（63．5％），较周围正常胃粘膜上皮明显降低（P〈0．05）。caspase-3的表达与胃癌的预后指标（如组织学类型，TNM分期等）明显相关性。结论人胃癌组织中caspase-3的表达较低。这一结果提示caspase-3低表达导致的细胞凋亡异常降低及增生过度可能是胃癌的发病原因之一。这一结果亦提示caspase-3与胃正常粘膜及肿瘤细胞的凋亡有关。Caspase-3可能是胃癌的预后指标之一。

简介：神经胶质瘤是中枢神经系统（CNS）最常见的一类肿瘤，占了颅内原发肿瘤的35％-60％。2007年世界卫生组织（WH0）中枢神经系统肿瘤分类中将胶质瘤分为Ⅰ-Ⅳ级，其中Ⅲ、Ⅳ级为恶性胶质瘤，大约占所有胶质瘤的77．5％。目前对神经胶质瘤的临床治疗采取以手术治疗为主，结合放疗、化疗等疗法的综合治疗．虽然能延长患者生存时间，但存在高复发率、高致残率、高病死率等问题，总体预后仍然较差。自20世纪70年代以来．维生素C（VC）抗肿瘤作用的研究日益进展，国外的医疗工作者已将其作为肿瘤治疗的补充和替代疗法之一．并报道了静脉注射维生素C治疗神经胶质瘤、卵巢癌、肾细胞癌、乳腺癌、大肠癌、非霍奇金淋巴瘤、前列腺癌、膀胱癌等肿瘤的临床病例，认为其能改善患者的临床症状、提高生存质量、延长生存期。本文就维生素C对神经胶质瘤的治疗作用做一综述。
