金属内支架置入联合三维适形放射治疗肝癌合并门静脉癌栓

Objective To study the clinical efficiency of metallic stent implantation in combination with three-dimensional conformal radiation therapy in the treatment of hepatocellular carcinoma (HCC) pa-tients with portal vein tumor thrombus. Methods 22 cases of HCC patients with portal vein tumor thrombus were devided into 2 groups: 10 patients (group A) recieved stent implantation in combination with conformal radiation therapy, 12 patients (group B) recieved stent implantation and transcatheter arterial chemoembolization. The adverse reactions, and liver function before and after treatment were compared between the two groups. The stent patency rate at 4, 6 and 12 months and the survival rate at 3, 6 and 12 months were followed up. Comparison of liver function was analyzed by Wilcoxon signed rank test. Compari-son of stent patency rate curves and survival curves was analyzed by Log rank test. Results The portal vein catheterization was successful in all the patients. The stents were successfully implanted by transhepatic portal vein approach, and portal vein stenosis was re-opened. There was no abdominal hemorrhage in all the patients, but there were symptoms of abdominalgia, fever, nausea, vomiting and flatulence of varying de-grees after interventional operation, and these symptoms were relieved by symptomatic treatment in one week. All patients in group A completed the treatment. Ⅰ-Ⅱ degree gastrointestinal tract reactions occurred in 3 cases, Ⅰ-Ⅱ degree myelosuppression occurred in 2 cases, and they were all completely relieved after treatment. The stent patency rate at 4, 6 and 12 months was 90%, 70%, 30% in group A; and 50%, 25%, 16.7% in group B (P < 0.05). The survival rate at 3, 6 and 1 2 months was 100%, 80%, 30% in group A and 91.7%, 41.7%, 16.7% in group B (P < 0.05). Conclusion Stent implantation combined with three-dimensional conformal radiation therapy is a good treatment for hepatocellular carcinoma with portal vein tumor thrombus and causes less damage to liver.     

胃泌素对结肠癌细胞中粘着斑激酶通路下游E-钙粘蛋白/β-连环蛋白复合物的影响

目的探讨胃泌素对结肠癌细胞CoLo320WT中粘着斑激酶（FAK）通路下游E-钙粘蛋白／β-连环蛋白（E-cadherin／β-catenin）复合物分布的影响；方法脂质体转染表达胃泌索受体CCK-2R的pCR3．1／OR质粒于结肠癌细胞CoLo320中。G418筛选出稳定表达CCK-2R的阳性克隆，RT-PCR鉴定，转染成功命为CoLo320WT。应用10^-8mmol／L 胃泌素（G17）以时间梯度（0h、1h、6h、12h、24h、48h）干预CoLo320WT细胞，同时应用10^-6mmol／L胃泌素受体拮抗剂L365，260干预CoLo320WT细胞30min，再予10^-8mmol／L胃泌素干预。采用免疫印迹法检测磷酸化的FAK Tyr397和总FAK的表达。采用免疫共沉淀和免疫印迹法检测CoLo320WT中TX-100溶解和未溶部分中的E-钙粘蛋白和β-连环蛋白的表达。用免疫细胞化学法观察E-钙粘蛋白和β-连环蛋白的在胞膜、胞质和胞核的分布。结果随着胃泌素干预时间的延长，细胞中磷酸化的FAK Tyr397的表达量呈增加趋势，12h达最大值。胃泌素受体拮抗剂L365，260阻断后磷酸化的FAK Tyr397表达减少。而胃泌素对总FAK没有明显影响。TX-100可溶性部分中E-钙粘蛋白和酽连环蛋白的量在胃泌素干预后表达减少，拮抗剂L365，260阻断后又增加。而TX-100不溶解部分中表达却相反。免疫细胞化学观察到在胃泌素干预下CoLo320WT细胞中E-钙粘蛋白和β-连环蛋白的分布发生胞质和胞核转移。结论胃泌素与其受体CCK-2受体结合，磷酸化的FAK Tyr397、激活FAK通路进而影响结肠癌细胞中E-钙粘蛋白和β-连环蛋白的分布，促进结肠癌细胞侵袭和转移。     

心脏泵血功能与淋巴细胞内及血清中钙、镁、铜、锌含量的关系

20例器质性心脏病患者进行心脏泵功能（简称泵功能）和淋巴细胞内及血清中钙、镁、铜,锌的测定,发现患者泵功能均低于正常,其淋巴细胞内钙、镁、锌亦明显低于正常对照组（p<0.01）。血清铜升高（p<0.05）:血清锌显著升高（p<0.01）。提示泵功能、淋巴细胞内及血清中微量元素含量之间有一定的相关性。

急性冠状动脉综合征患者树突状细胞功能的变化

急性冠状动脉综合征（acute coronary syndrome,ACS）是一组由急性心肌缺血引起的临床综合征,其病理基础是不稳定的动脉粥样硬化斑块发生变化,斑块中炎症反应强烈从而导致斑块破裂。免疫炎症反应的发生和放大需要抗原递呈,而树突状细胞（dendritic cells,DC）是机体功能最强的专职抗原递呈细胞。
