术前MRCP对LC难易预测价值的研究

目的探讨胆囊磁共振胰胆管成像（magnetic resonance cholangiopancreatography，MRCP）显像结果与腹腔镜胆囊切除术（laparoscopic cholecystectomy，LC）难易程度关系及预测价值、方法对106倒患者胆囊MRCP显像结果（包括胆囊大小、囊壁厚度、结石大小、周围组织粘连度、胆囊颈部结石、胆囊角度、胆囊管长度及胆囊位置）与LC术中情况进行分析。结果LC难易程度与胆囊管长短及胆囊颈部有无结石相关（P〈0.05），而与患者性别、年龄、胆囊管角度、胆囊体积大小、胆囊壁厚薄、胆囊周围情况及胆囊位置没有相关性（P〉0．05）。结论胆道疾病术前常规行MRCP对预测LC难易程度有很大价值，值得推广应用．     

Ezrin在胃癌细胞的表达及与胃癌细胞侵袭能力的关系

目的检测胃癌细胞株中Ezrin的表达情况与胃癌细胞株的侵袭能力，探讨Ezrin的表达与胃癌细胞侵袭能力的关系。方法分别采用Western blot和Real-Time PCR的方法，检测Ezrin在胃癌细胞株的表达情况，运用以胶原为基础的细胞侵袭试验检测胃癌细胞株的侵袭能力。结果Ezrin在胃癌细胞株中的表表达存在差异，其中MKN-45表达水平最高，N-87表达水平最低；侵袭试验显示MKN-45的侵袭能力最强，N-87侵袭能力最弱。结论Ezrin在胃癌细胞中的表达存在差异，Ezrin的表达水平与胃癌细胞的侵袭能力成正相关。     

BRAF V600E突变对甲状腺乳头状癌发生及预后的影响

甲状腺乳头状癌(papillary thyroid cancer,PTC)是甲状腺癌最常见的病理类型.PTC通常预后良好,但近年来甲状腺癌的发病率逐年攀升.随着患病人数的不断增多,中晚期难治性甲状腺癌患者不再少见.因此,越发庞大的甲状腺癌患者群体的管理与诊治已成为巨大的考验.BRAF V600E基因突变是乳头状癌经典DNA相关标志物,目前已被广泛应用于甲状腺癌的术前诊断和预后评估,并且作为潜在的治疗靶点受到越来越多的关注.因此,正确全面的了解BRAF V600E基因突变可以帮助我们对PTC的发生、发展及生物学行为有更进一步的了解,并为PTC患者管理方式与治疗策略提供新的方向.     

结肠中血管根部切断在右侧结肠癌根治术中的价值

Objective To compare the long-term outcome of ligating the middle colic artery in radical surgical treatment of right hemicolon cancer. Methods The operation safety, complications and short-term outcome between two groups of patients undergone either ligating the middle colic artery from its root (A group) or ligating the middle colic artery from its right branch (B group) in right bemicolectomy for colon cancer. Results Between January 1981 and December 2004, 308 patients underwent radical right hemicolectomy in which 103 patients were treated by ligating the middle colic artery from its roots (Jan. 1996 to Dec. 2004, A group), and 205 patients via ligating the middle colic artery from the roots of its right branch (Jan. 1981 to Dec. 1995, B group). The complications were compared between the two groups (P>0.05). The mean follow-up time of A and B group were (50.1±7.2) months and (49.1±7.2) months respectively. Local recurrences of 1-year, 3-year and cumulative survival probability at the 60th month in group A were 1.9%, 13.6% and (78.3±3.4)% respectively, which were significantly better than 19.0%, 24.9% and (64.8±2.8)% in group B (P<0.05). Conclusion Ligating the middle colic artery from its root in right hemicolectomy can be performed safely and effectively, which is to be highly recommended in curative resection of right colon.     

Ezrin在肿瘤转移中的作用

如何预防和控制肿瘤转移是提高肿瘤患者生存率的关键。Ezrin,作为连接膜和细胞骨架的蛋白,通过组成膜细胞骨架相关复合体和形成特殊膜结构对细胞活动进行调节,如细胞存活、粘附和运动,而细胞的这一切活动都与肿瘤的发生、发展和转移有重要关系。Ezrin的高表达可以促进肿瘤细胞的转移。本文就Ezrin在肿瘤转移中的作用及其可能的分子机制作一综述。

进展期胃癌的新辅助化疗

新辅助化疗又称术前化疗,系指在恶性肿瘤局部治疗、手术或放疗前给予的全身或局部化疗.大量的临床试验表明新辅助化疗可以明显降低胃癌患者的临床分期,增加手术切除成功率及延长患者的生存时间;对剖腹探查后无法切除的胃癌患者,新辅助化疗可以使再次手术完全切除肿瘤成为可能,遵循循证医学方法深入研究新辅助化疗这一治疗手段,可以进一步提高进展期胃癌的治疗效果.     

高龄胃癌患者的临床特点及围手术期处理

目的：探讨高龄胃癌患者的临床表现、治疗特点及其对术后并发症的影响,以及高龄胃癌患者的围手术期处理。
方法：回顾性分析手术治疗的101例高龄胃癌患者的临床资料,着重分析术前合并症与术后并发症的治疗。
结果：大于70岁的高龄胃癌患者（高龄组）有临床表现多无特异性、病变部位及范围不同、术前合并症多等临床特点。高龄组术前合并症发生率为49.5%(50例),对照组（小于70岁的胃癌患者）为21.3%,两组差异有统计学意义(P<0.05);高龄组术后并发症发生率为18.8%,对照组为15.2%,但两组无统计学差异(P>0.05);高龄组胃癌手术切除98例(97.0%),其中根治性切除87例(86.1%)。
结论：高龄胃癌患者术前合并症较多,术后并发症发生率也较高。加强此类患者的围手术期处理,对减少术后并发症,提高生存率和生活质量有重要意义。
