背景与目的肿瘤的浸润和转移严重威胁着人类生命,正确认识和评估肿瘤的生物学行为有重要的临床意义。整合素和细胞外基质(ECM)的异常表达在肿瘤浸润转移过程中发挥着重要作用。本研究的目的是探讨整合素α5、β1(integrinα5、β1)与细胞外基质(ECM)在人非小细胞肺癌(NSCLC)中的表达及其与淋巴结转移及患者预后之间的关系,评估它们在肿瘤转移过程中的作用。方法采用免疫组化方法测定119例NSCLC组织中整合素α5、β1及Ⅳ型胶原、纤连蛋白(fibronectin,FN)、细胞黏合素的表达,探讨其与临床病理特征特别是与淋巴结转移的关系,并分析其与患者预后的相关性。结果Ⅳ型胶原表达与淋巴结转移呈负相关(P〈O.01),与患者预后呈正相关俨〈0.01),而整合素α5和β1表达与淋巴结转移呈正相关(P〈0.01),且整合素o5表达与患者预后呈负相关(P〈0.01)。整合素α55表达与整合素β1表达呈正相关而与Ⅳ型胶原表达呈负相关。Ⅳ型胶原在分期较早和分化较好时表达率较高,整合素α5和β1则相反。结论整合素α5和β1的高表达与ECM蛋白的低表达明显与NSCLC的淋巴结转移及患者不良预后相关,整合素α5与Ⅳ型胶原可能可以作为评估患者预后的重要指标。 相似文献

糖尿病是一种慢性的全身代谢性疾病,以高血糖为其共同主要标志.目前世界上约有1.7亿之多的糖尿病患者,随着物质生活水平提高,糖尿病患者明显有上升的趋势,以成为严重危害人民健康的一大杀手.临床比较重视的是药物控制和饮食调理,而患者的心理在漫长的病程中倍受煎熬,不良的情绪因素会引起体内某些激素的大量分泌,如胰高血糖素,肾上腺皮质激素的升高会引起糖尿病病情反复.因此,只有药物控制、饮食调理、心理护理三管齐下,才能有效的控制病情,鼓励患者增加信心在生活上有规律,身体情况许可者,可进行适当的运动,注意个人卫生,预防感染.对有微血管病变的患者,可设法促进周围循环.按时测体重,以作为计算饮食和观察疗效的参考.饮食治疗是一项基础治疗措施,不论糖尿病类型,病情轻重或有无并发症,也不论是否应用药物治疗,都应严格和长期执行. 相似文献

IA期非小细胞肺癌的肿瘤大小对其预后的影响 总被引:1,自引:0,他引:1
背景与目的 肿瘤大小对预后的影响在肺癌的不同分期组间已明确,但其在同一分期中,尤其是直径小于3cm的肿瘤中对预后的影响尚未明确。本研究的目的是探讨IA期非小细胞肺癌中肿瘤大小对预后的影响。方法 回顾性分析自1995年1月至2003年12月我院胸外科手术治疗IA期非小细胞肺癌142例,用Kaplan-Meier生存曲线统计不同肿瘤大小患者的生存率,并对发病年龄、性别、病理类型、肿瘤大小、手术方式以及是否接受放化疗等因素进行COX回归比例风险模型多因素分析。结果 全组肿瘤直径≤2.0cm者60例,2.1~3.0cm者82例。全组3年、5年生存率分别为84.41%、70.89%,其中肿瘤直径≤2.0cm组分别为94.91%和81.40%,2.1~3.0cm组分别为82.18%和64.91%(P=0.0353)。单因素及多因素分析均显示,肿瘤大小为独立的预后因素。结论 肿瘤大小是IA期非小细胞肺癌的独立预后因素。临床工作中应进一步提高影像学诊断水平,使患者获得更早期的治疗。 相似文献

Objective To investigate the sensitivity, specificity and clinical significance of detecting circulating tomor cells (CTCs) in NSCLC. Methods Twenty-five patients who undetwent surgical resection for NSCLC form Jan 2007 to Apr 2007 were in- cluded in this study. Control group included 10 patients with benign pulmonary diseses (2 case of hamartoma and 8 case of pulmonary tu berculosis) and 10 healthy volunteers. The pulmonary veins blood and peripheral vein blood were collected respectively. The CD326 immunomagnetic beads and CK-fluorescein isothiocyanate (CK-FITC) were served as the marker antibodies of CTCs. Firstly mononu- clear cell marked by minibeads conjugated with CD326, the mononuclear cells were enriched and separated though Magnetic-activated cell separation(MACS), then the positive separtion cells were marked by anti-CK-FTTC and anti-leukocyte antibody CD45-phyco- erythrine (anti-CD45-PE), finally those cells detected and analyzed by flow cytometry . Results For stage Ⅰ and stage Ⅱ patients (n= 16), CTCs were detected from peripheral vein blood of in 5 (5/16, 31.25%) and from pulmonary veins blood in 9 (9/16, 56.25%). For stage Ⅲ and stage Ⅳ, CTCs were detected from peripheral vein blood in 5 (5/9, 55.56%) and from pulmonary veins blood in 9(7/9,77.78%).For stage Ⅰ,CTCs were detected from peripheral vein blood in 3(3/13,23%)and from pulmo- nery veins blood in 8(8/13,61.54%).The whole CTCs positive detection rate from pilmonary veins blood was 64%(16/25)which higher than feom peripheral vein blood(40%,10/25)(P<0.05).Conclusion The method was set up by MACS combined with FCM to detect the CTCs of pulmonary veins blood and peripheral vein blood of patients.with NSCLC,MACS combined with FCM may improve detection rate of CTCs.This technique appears to be an efficient to detect circulating tumor cells and may be important for dinical practice in the future. 相似文献
