肝内胆管结石合并胆管癌组织中ERBB家族蛋白表达及其临床意义

目的 :探讨肝内胆管结石合并胆管癌组织中erb B1(EGFR)和erb B2(HER2)的表达差异及其临床意义。方法 :收集94例肝内胆管结石合并肝内胆管癌患者的肝内胆管癌组织和50例癌旁肝组织样本,组织切片后进行EGFR和HER2免疫组化染色检测,分析癌与癌旁组织的表达差异;对部分患者进行EGFR分子靶向治疗(埃罗替尼,Erlotinib,150 mg/d,1个疗程),并进行5年无瘤生存分析。结果:两组EGFR阳性表达率分别为58.5%(55/94)和26.0%(13/50),差异有统计学意义(P<0.001);两组HER2阳性表达率分别为33.0%(31/94)和16.0%(8/50),差异有统计学意义(P<0.05)。在胆管癌组中,EGFR和HER2阳性患者的肿瘤组织学分级、浸润深度和肝门淋巴结转移明显高于阴性患者,差异有统计学意义(P<0.05)。在胆管癌患者中EGFR或HER2阳性患者的5年无瘤生存率显著低于阴性患者(P<0.05)。进一步分子靶向治疗发现,EGFR阳性患者埃罗替尼治疗后生存期延长,5年无瘤生存率较EGFR和HER2均阳性者高(81.3%vs.59.4%),但差异无统计学意义(P>0.05)。结论:EGFR和HER2高表达在肝内胆管结石合并肝内胆管癌的发生发展中可能发挥重要作用,且二者高表达与肿瘤的恶性程度以及临床预后密切相关,并可能对临床分子靶向治疗具有指导意义。     

微型腹腔镜与开放手术治疗小儿鞘膜积液疗效比较

目的:比较应用微型腹腔镜与开放手术治疗小儿鞘膜积液的临床疗效。方法:回顾性分析2010年1月~2013年12月我院68例应用微型腹腔镜(腹腔镜手术组)及76例应用传统开放手术(开放手术组)治疗鞘膜积液患儿的临床资料,比较两组手术时间、术中出血量、术后并发症、术后住院时间、住院费用及复发率情况。结果:与开放手术组比较,腹腔镜手术组手术时间、术中出血量、术后住院时间及并发症均明显减少,但住院费用高于开放手术组,差异均有统计学意义(P0.05),复发率比较差异无统计学意义(P0.05)。结论:微型腹腔镜治疗小儿鞘膜积液安全有效,创伤小,恢复快,术后并发症少,特别是同时治疗双侧鞘膜积液时相对于传统开放手术,优势更明显。     

Effect of p38 mitogen-activate protein kinase on MUC5AC protein expression of bile duct epithelial cells in hepatolithiasis patients

Primary hepatolithiasis is a common bile duct disease with benign nature but complicated mechanisms. Current studies have revealed its correlation with cytokine release by chronic inflammation, which also increased mucin (MUC) synthesis. This study investigated the role of p38 mitogen-activated protein kinase (MAPK) in regulating cytokine release and mucin synthesis, in an attempt to elucidate the role of p38 signaling molecule in the pathogenesis of hepatolithiasis. In human intrahepatic bile duct endothelial cells (HIBECs), lipoprotein (LPS) was used to induce the high expression of MUC. Small interference RNA (siRNA) was then used to silencing p38 gene expression. Cytokines including interleukin (IL)-1β and tumor necrosis factor (TNF)-α were measured, along with MUC5AC protein and mRNA expression assay. The interference of p38 gene expression inhibited the release of IL-1β and TNF-α in cultured cells. It also depressed both mRNA and protein levels of MUC5A. P38 MAPK signal pathway may be involved in the formation and progression of hepatolithiasis. This study provides potential new strategy for treating hepatolithiasis using p38 MAPK signal pathway as the drug target.     

One-Step Multichannel Percutaneous Transhepatic Cholangioscopic Lithotripsy Applied in Bilateral Hepatolithiasis

Background

The aim of this study was to compare the outcomes of one-step multichannel percutaneous transhepatic cholangioscopic lithotripsy (PTCSL) with traditional PTCSL in the treatment of bilateral hepatolithiasis.

Methods

From February 2011 to June 2015, 156 patients with bilateral hepatolithiasis received surgical treatment in our department. Among these patients, 81 received one-step multichannel PTCSL (group A), and the remaining 75 received traditional PTCSL (group B).

Results

Compared with group B, group A was characterized by a significantly shorter operation time (83.7 ± 28.5 min vs 118.1 ± 41.5 min; P = 0.000), hospital stay (11.1 ± 3.4 d vs 17.8 ± 5.6 d; P = 0.034), and postoperative hospital stay (6.9 ± 3.1 d vs 9.6 ± 4.5 d; P = 0.026). In addition, the immediate clearance (62.9% vs 45.3%, P = 0.027) and final clearance (90.1% vs 78.7%, P = 0.048) rates were higher in group A than in group B. During the follow-up period, stone recurrence was significantly less common in group A than in group B (13.6% vs 26.7%, P = 0.041). Multivariate Cox analysis showed that the PTCSL method (HR = 2.32, 95% confidence interval [CI] = 1.09–4.90, P = 0.028), bilateral biliary stricture (HR = 4.17, 95% CI = 1.73–10.03, P = 0.001), and stones located in segments I (HR = 7.75, 95% CI = 3.67–16.38, P = 0.000) were independent predictors of recurrence.

Conclusions

Compared with traditional PTCSL, one-step multichannel PTCSL was more efficient and effective in the treatment of bilateral hepatolithiasis.
