Inhibitory effects of prostaglandin E₁ on activation of hepatic stellate cells in rabbits with schistosomiasis

Hepatobiliary & Pancreatic Diseases International 2007年第2期6卷 176-181页

BACKGROUND: Liver fibrosis is the result of an imbalance between synthesis and degradation of extracellular matrix proteins of the liver. At the cellular and molecular levels, this progressive process is mainly characterized by activation of hepatic stellate cells (HSCs). Schistosoma japonica is one of the most prevalent causes of liver fibrosis in China. It is characterized by hepatocyte damage, inflammation, and chronic parasite egg-induced granuloma formation leading to fibrosis. This study aimed to investigate the inhibitory effects of prostaglandin E1 (PGE1) on activation of HSCs and the alteration of type Ⅰ and Ⅲ collagen in rabbits with schistosomiasis. The study may promote the clinical application of praziquantel and PGE1 as a combined therapy to reverse hepatic fibrosis caused by schistosomiasis. METHODS: Rabbits were percutaneously infected with cercaria of S. japonicum. Seven rabbits were subjected to intravenous injections of PGE1 (2.5 μg/kg daily) from days 60 to 120 after infection. The ultrastructural changes in activated HSCs were observed under transmission electron microscopy. The expression of α-smooth muscle actin (α-SMA) was detected by immunohistochemistry. Fibril-forming collagens were detected by picrosirius staining. RESULTS: Activation of HSCs was a characteristic alteration in schistosome-induced hepatic fibrosis. The expression of contraction-related α-SMA and thecontent of collagens were increased. Exogenous PGE1 markedly inhibited the activation of HSCs and reduced the expression of α-SMA around the hepatic sinusoids (P<0.01). The contents of type Ⅰ and Ⅲ collagens were significantly attenuated. The ratio of staining area to the whole field (10×3.3) under a polarized light microscope in the untreated and treated groups was 37.25±9.71 vs. 13.38±4.24 (P<0.01) and 9.66±3.52 vs. 6.23±1.81 (P<0.05), respectively. CONCLUSIONS: Activation of HSCs may play a key role in the progress of schistosome-induced hepatic fibrosis. PGE1 effect

Liver retransplantation:report of 80 cases and review of literature

Hepatobiliary & Pancreatic Diseases International 2006年第2期5卷 180-184页

作者： zhongyang shen ZhiJun Zhu YongLin Deng Hong Zheng Cheng Pan YaMing Zhang Rui Shi WenTao Jiang JianJun Zhang Orient Organ Transplant Center First Central Hospital Tianjin 300192 China. shenzy@***.

BACKGROUND: Because the orthotopic liver transplantation (OLT) was performed widely in recent 5 years throughout China, the proportion of recipients whose graft function deteriorated to be retransplantation candidates increased gradually. This study was undertaken to analyze clinical experience of orthotopic liver retransplantation (re-OLT) at our center. METHODS: The medical records of 80 patients who had undergone liver retransplantation at our center from January 1999 to July 2005 were analyzed retrospectively, including indications and timing of retransplantation, surgical techniques, and the causes of death. RESULTS: The commonest cause leading to hepatic graft loss and subsequent retransplantation was biliary complications in 36 patients (45%). The patients underwent retransplantation more than 30 days after their primary transplant recovered better than those who underwent retransplantation within 8-30 days after primary transplantation (peri-operative mortality 19.6% versus 70%). Sepsis (12 of 22 patients, 54.5%) and multiple organ failure (4 of 22 patients, 18.2%) were leading causes of re-OLT recipient deaths. CONCLUSIONS: Proper indications and optimal operative time, surgical procedures, perioperative monitoring and appropriate postoperative treatment contribute to the improvement of the survival rate of patients after liver retransplantation.

目的探讨肝移植对肝性脊髓病(hepatic myelopathy,HM)的远期疗效,并检索归纳国内外HM肝移植后结果。方法回顾性分析2006年1月至2022年10月在天津市第一中心医院因HM行肝移植术24例成年受者的临床资料,根据下肢症状严重程度、肌肉僵硬程度、能否独立行走、肌力等指标对HM的严重程度进行详细分类,并观察肝移植术后受者的远期预后。另外以"肝性脊髓病+肝移植"和"Hepatic Myelopathy+Liver Transplantation"为关键词分别在知网、谷歌学术数据库和PubMed、Web of Science上检索发表于2000年1月至2022年10月的文献。归纳总结相关文献报道的病例诊治情况和预后转归。结果24例肝移植受者术后肝功能和血氨均顺利恢复,多数受者的临床症状有所改善。术后随访12~190个月,19例受者HM分级较前降低,其中4例受者肢体功能完全恢复;另5例受者的HM分级较术前没有变化,但其中4例肌力及独立行走能力均有不同程度改善。文献检索纳入了17例国内外HM肝移植受者,16例经肝移植治疗后症状均有不同程度改善,1例症状没有改善。结论对于大多数HM患者,肝移植可有效改善其临床症状,有助于HM的远期恢复。

中国肝移植事业经过20年的快速发展,已成为国际肝移植舞台中的重要一员。针对乙型肝炎相关性肝病和肝癌,我国推出了符合自身国情的肝移植相关指南和标准,进一步扩大了肝移植受助人群。同时,科技水平的进步有力促进了我国肝移植外科技术的不断创新,在腔镜供体手术、异种肝移植、无缺血肝移植、活体肝移植等方面我国已然走在了世界前列。目前,供体短缺仍然是限制我国肝移植事业发展的重要因素之一,我国器官捐献工作任重而道远。

采用数值模拟方法研究了球窝结构对U型通道传热和阻力特性的影响,U型通道的一侧布置了球窝结构;采用SSTk-ω和大涡模拟(LES)湍流模型,对不同Re下的球窝强化传热性能进行了分析。结果表明:U型通道中第2列通道传热系数明显大于第1列通道,180°转弯角附近存在明显的二次流现象且传热系数较高;球窝结构的引入能明显强化U型通道的传热性能,球窝表面的平均Nu沿着流动方向逐渐减小,经过180°转弯角后急剧增大,球窝结构强化传热带来的压力损失非常小,几乎与光滑通道相当;RANS方法计算出的球窝表面Nu要大于LES方法的时均结果,相比LES方法,RANS方法判断的球窝腔内再附点更加靠近上游。
