中老年梗阻性大肠癌102例的临床分析

目的分析8年来中老年梗阻性大肠癌的临床特点和外科治疗。方法回顾性总结我院1993～2001年102例中老年梗阻性大肠癌的临床治疗资料。结果大肠癌梗阻占老年急性肠梗阻的50.45%,居首位。梗阻发生部位以右半结肠区最多,占54.58%,左半结肠区仅占13.49%;所有患者均经手术治疗,其中一期切除吻合80例,占78.4%;短路手术18例,占17.6%;单纯造瘘术4例,占3.9%;死亡2例,死亡率2%。结论提高对中老年梗阻性大肠癌临床特点的认识,正确地选择手术时机和合理的手术方式能获得良好的预后。加强围手术期各器官功能支持和营养代谢支持是减少死亡率的重要环节。重视老年生理变化特点,警惕肿瘤所致的消化道症状,早期诊治大肠癌以减少肠梗阻发病率。

Therapeutic applications of bone marrow-derived stem cells in liver transplantation for end-stage liver diseases

Today, liver transplantation (LT) is the only established treatment for end-stage liver diseases. The de- velopment of LT, including OLT, cadaveric LT, split LT, living donor LT (LDLT), brings hopes to patients with these diseases. However, increasing donor shortage, rejection and life-long immunosuppression with its side effects are the major limitations of this therapy strategy. Bone marrow-derived stem cells (BMDSCs) are capable of differentiating into hepatocyte-like cells and contribute to liver injury repair. The microenvironment of liver injury caused by rejection, ischemia/reperfusion, loss of liver mass, recurrence of HCV and "small-for-size syndrome" after LT can attract a variety of bone marrow-derived stem cell population to the peripheral circulation and then migration to the injury liver to promote the hepatic function restoration. Additionally, BMDSCs can also take part in the functional regeneration of living donor liver after LDLT. This participation in liver regeneration may be associated to the interac- tion between SDF-1and its receptor CXCR4, involving HGF, IL-8, MMP9, and VEGF/VEGFR-2. BMDSC with its bio-characteristics could maintain the allograft tolerance from different angles and in different ways. In conclusion, BMDSCs transplantation, as a new assistant therapeutic method for LT, will ex- pand the space of LT, and provide more survival opportunities for the patients suffering liver diseases in the future.     

56例牙髓治疗后疼痛临床分析

目的:为提高对牙髓治疗后疼痛的防范认识.方法:对56例牙髓治疗后疼痛的病例进行临床分析.研究发现,引起疼痛原因有:25例牙髓炎未完全开髓,髓腔未能有效减压;8例临床误诊,对慢性根炎周炎急性发作,无通根治疗压力未减;16例塑料化治疗适应症掌握不严;4例干髓治疗有2例并发残髓炎,2例继发根炎尖;3例根管治疗器械折断未取出而充填.结论:牙髓治疗后疼痛原因是多方面,只有术前全面观察,正确的临床诊断,严格掌握适应症,术中采取规范有效的治疗措施,才是减少牙髓治疗后疼痛的有效措施.

治疗癌症的重粒子加速装置

重粒子是指1个原子核或者几个的介子,同电子、中子和质子相比,质量更大,所以称为重粒子,也叫作重子。所使用的重粒子是氦、碳、氖、硅和氩等已被离子化的原子核。 灭癌是人类的宏愿,过去在寻找治病的方法中,除了早期切除和服抗癌药物之外,还研究了BRM(生物反应修改)、温热疗法、X射线—γ射线辐照等
