  • 简介:目的研究转录因子扭曲基因(Twist)在喉鳞癌(LSCC)中表达及其通过对上皮型钙黏附蛋白(E-cadherin)、神经型钙黏附蛋白(N-cadherin)作用在判断肿瘤生物学行为方面的意义。方法采用免疫组织化学SP法及反转录聚合酶链反应(RT-PCR)方法检测49例喉鳞癌及20例癌旁组织中Twist、E-cadherinN-cadherin基因表达情况。结果Twist在喉癌组织中阳性表达率(61.22%)明显高于癌旁组织(25%)(P〈0.01);Twist在喉癌组织中mRNA相对表达量(0.93±0.39)明显高于癌旁组织(0.57±0.24)(P〈0.01);Twist在喉癌中蛋白及mRNA表达均与淋巴结转移、临床分期相关,而与肿瘤病理学分级、临床分型及年龄无关。在mRNA及蛋白水平,Twist与E-cadherin,N-cadherin与E-cadherin表达均呈负相关;Twist与N-cadherin均呈正相关。结论Twist在喉鳞癌中过度表达,可能通过分别上调N-cadherin下调E-cadherin表达,进而在喉鳞癌浸润、转移过程中发挥重要作用。

  • 简介:目的:观察超声乳化白内障吸出术联合人工晶状体(IOL)植入治疗激光周边虹膜切除术后闭角型青光眼治疗效果。方法:激光周边虹膜切除术后闭角型青光眼并白内障患者39例(39眼),被分为两组,Ⅰ组须用抗青光眼药控制眼压,Ⅱ组不须用抗青光眼药控制眼压,患者均行超声乳化白内障吸出折叠式人工晶状体植入术,术后随访3mo。结果:两组术后最佳矫正视力均较术前显著提高(P〈0.05)。术后3moⅠ组眼压为15.72±3.02mmHg,1/组为16.30±3.81mmHg,两组眼压均比术前明显下降,有显著性差别(P〈0.05)。Ⅰ组中央前房深度由术前1.64±0.45mm加深至术后3mo3.21±0.41mm,Ⅱ组中央前房深度由术前1.92±0.52mm加深至术后3mo3.18±0.39mm.两组术后中央前房深度均比术前明显加深,有显著性差异(P〈0.05),前房角明显增宽。结论:超声乳化白内障吸出人工晶状体(IOL)植入术不仅能提高激光周边虹膜切除术后青光眼视力,而且可彻底解除闭角型青光眼瞳孔阻滞。

  • 简介:目的:系统评价拉坦前列素(Latanoprost)滴眼液与噻吗心安(Timolol)滴眼液降眼压有效性安全性。方法:计算机检索PubMed,Medline,CNKI及中国生物医学文献数据库收录,并辅以手工检索、因特网搜索有关拉坦前列素与噻吗心安治疗原发性开角型青光眼高眼压症随机对照试验(RCT)。按照纳入排除标准限定研究对象,通过Jadad评分量表进行文献质量评估后,针对眼压下降比例、药物不良反应2项内容,使用Cochrane协作网提供RevMan5.0软件进行Meta分析。结果:共纳入9项RCT,合计555例患者。Meta分析结果显示:(1)拉坦前列素滴眼液与噻吗心安滴眼液降眼压效果,在2,6,12wk时差异均有统计学意义(P<0.01),加权平均差(WMD)分别为:在2wk[WMD=-0.76,95%CI(-1.32,-0.20)],在6wk[WMD=-1.15,95%CI(-1.68,0.63)]12wk[WMD=-1.01,95%CI(-1.42,-0.61)]。(2)随访结束时,结膜充血、异物感为拉坦前列素两种较为常见不良反应,但其发生率拉坦前列素组与噻吗心安组比较,结膜充血发生率[OR=2.25,95%CI(0.99,5.08)],异物感发生率[OR=2.48,95%CI(1.02,6.03)],显示二者差异均无统计学意义。结论:治疗原发性开角型青光眼高眼压症,拉坦前列素降眼压效果在用药12wk内较噻吗心安好;两者在12wk内引起结膜充血、异物感、虹膜色素加深、视野损害等不良反应方面,差异不明显。由于纳入研究样本量偏小,且方法学质量中等,致使本系统评价结果论证强度不高,因此还需要开展更多高质量临床随机对照研究,以便更客观、准确、全面地评价其疗效安全性。
