Objective To investigate the research development of the liver stem cell(LSC) and to predict its future application. Methods Based on our own researches and combined with the review of the related literature at home and abroad, we analyzed and evaluated the latest development of the research on the LSC. Results We knew the differentiation and proliferation of the LSC towards some kinds of specified cells were affected by many factors; and the researches on the LSC in regard to its activation, isolating culture, bolting, and evaluation still needed further improvements. Conclusion With the development of the research, the liver stem cell can become a new seed cell to cure some liver diseases.
Objective To analyse the clinical features of Peutz-Jeghers syndrome and its canceration, and to summarize the management and the follow-up strategy for patients with Peutz-Jeghers syndrome. Methods Clinical data of 30 patients with Peutz-Jeghers syndrome dating from October 1985 to September 2005 in West China Hospital of Sichuan University were analyzed retrospectively. Results Fourteen (46.67%) definite family histories of Peutz-Jeghers syndrome were found. Pigmentation of skin and mucosa, abdominalgia and hematochezia were major clinical manifestations of the syndrome. There were 18 patients (60.00%) complicated with intussusception and acute intestinal obstructions, 16 patients (53.33%) with gastrointestinal bleeding, and 6 patients (20.00%) developed malignancy. The frequent types of malignancy were carcinoma of small intestine (3 cases), colon carcinoma (2 cases) and gastric carcinoma (1 case) in order. The mean age of the canceration-diagnosed patients was 32 years old. The type of pathohistology of all the malignancy was poorly differentiated mucus adenocarcinoma. High-frequency endoscopic electroresection, orthdox polypectomy and enterectomy were the major means of treatment. Conclusion Patients with Peutz-Jeghers syndrome are at high risk of canceration at relatively early ages and usually the differentiation of the tumor is poor. Endoscopy should be performed regularly and the high-frequency electroresection is an effective therapy in disposing intestinal polyp. Screening can also improve the efficacy of Peutz-Jeghers syndrome.
目的 探讨妊娠期并发急性胰腺炎(APIP)的病因、发病机理、临床特点及防治措施. 方法 对四川省宜宾市第二人民医院和四川大学华西医院1995年1月至2006年12月期间收治的72例APIP患者的临床资料进行回顾性分析. 结果 本组72例中,属轻型急性胰腺炎(MAP)者49例(68.06%),重症急性胰腺炎(SAP)者23例(31.94%); 有胆囊炎合并胆囊结石病史者43例(59.72%),伴高脂血症者21例(29.17%).采用非手术治疗56例,手术治疗16例,孕妇治愈66例(91.67%),死亡6例(8.33%),死因为多器官功能障碍综合征、急性呼吸窘迫综合征及严重复腔感染; 终止妊娠16例(均为32～38周妊娠),56例继续妊娠; 72例中双胎2例,胎儿死亡共15例(20.27%); 漏诊、误诊6例.结论 APIP的发生与胆结石和高脂血症有关,并于妊娠中晚期发病率高; 其临床表现复杂,易误诊,对孕妇及胎儿威胁极大; 把握该疾病的特点,提高对APIP的认识和警惕性,及时准确的诊断与"个体化"的治疗原则,适时终止妊娠,可以提高其治愈率,降低母婴死亡率.
