Effects of α1-adrenergic receptor on the proliferation of cholangiocarcinoma cells

Objective To investigate the correlation between α1-adrenergic receptor and the pathological behavior of cholangiocarcinoma, and the effects of norepinephrine (NE) on the proliferation of cholangiocarcinoma cell line QBC939. Methods Thirty-six samples of cholangiocarcinoma were resected in Southwest Hospital from August 2002 to March 2008. The expression of α1-adrenergic receptor in the 36 samples of cholangiocarcinoma tissue and 4 samples of normal bile duct tissue were detected by SABC technique. The proliferation of cholangio-carcinoma cell line QBC939 was detected after processing the cells with NE, phentolamine and prazosin. All the data were analyzed by chi-square test. Results The high positive expression rate of α1-adrenergic receptor was 68% (17/25) in patients with lymph node metastasis, which was significantly higher than 9% (1/11) in patients without lymph node metastasis (χ2=10.604, P<0.05). The high positive expression rate of α1-adrenergic receptor was 85% (11/13) in patients with middle and low positioned cholangiocarcinoma, which was significantly higher than 30% (7/23) in patients with hilar cholangiocarcinoma (χ2=9.753, P<0.05). NE promoted the proliferation of cholangiocarcinoma cell line QBC939 by stimulating the expression of α1-adrenergic receptor, and in a concentration-dependent manner. The proliferative effect was weakened as time passed by, and it was eliminated by phentolamine and prazosin. Conclusions The expression of α1-adrenergic receptor is diverse due to lymph node metastasis and the location of the tumor, α1-adrenergic receptor with high expression may play an important role in the proliferation and metastasis of cholangiocarcinoma.     

肝胆管结石合并胆管癌的诊断与治疗(附62例报告)

目的总结并探讨肝胆管结石合并胆管癌的诊治经验。方法总结2000～2008年第三军医大学西南医院收治的62例肝胆管结石合并胆管癌病人的临床资料。结果本组病例中肝胆管结石合并胆管癌都发病率为发生率5．45％;术前诊断率为85．5％（53／62）;根治性手术率38．7％（24／62）;病理诊断为胆管腺癌及粘液癌;随访45例,行根治性手术病例平均存活23个月,行引流术病例存活平均存活8个月,仅行探查术病例存活平均4个月。结论胆管癌的发生与肝胆管结石有关;伴有结石的胆管癌疗效较差,应重视胆管结石的早期根治性治疗,以防止胆管癌的发生;姑息性手术可提高生活质量。

大鼠肝脏缺血再灌注损伤中TNF-α的变化

肝脏缺血再灌注损伤是肝脏和创伤外科疾病中常见的病理过程,许多疾病均涉及到这一过程,如处理严重的肝外伤、施行广泛的肝叶切除、肝移植以及休克、感染等。导致肝脏缺血再灌注损伤的原因众多,确切机制目前仍不十分清楚。既往研究证实氧自由基及钙超载参与了肝脏缺血再灌注损伤,近年来,细胞因子在肝脏缺血再灌注损伤中的作用受到了国内外学者的关注,其中肿瘤坏死因子-α(tumor necrosis factor alpha,TNF-α)为最具代表性的一种,它在烧伤、急性肝坏死以及梗阻性黄疸中的作用已有研究,而在肝脏缺血再灌注损伤中的作用研究较少。我们在实验中制作肝脏缺血再灌注损伤模型,观察了肝脏缺血再灌注后血浆TNF-α,透明质酸(hyaluronic acid,HA),丙氨酸氨基转移酶(glutamic-     

联合肝叶及部分胰头、十二指肠切除治疗Nevin V期胆囊癌六例

原发性胆囊癌是胆系常见的一种高度恶性肿瘤，本病早期多无症状，一旦临床发现多属晚期，易发生肝脏直接浸润和周围脏器侵犯，并易于发生淋巴结转移，手术切除率低，预后及5年生存率差。近年来，随着对胆囊癌转移方式研究的深入，以及现代外科综合技术的不断发展，晚期胆囊癌的手术切除率和术后生存期均有明显的提高。[第一段]
