早、中期胃癌的临床病理学研究(附75例报告)

目的　了解早、中期胃癌的临床、胃镜和病理学特征。方法　回顾性分析我院 11年中经外科手术和病理诊断的 75例早、中期胃癌患者的临床、胃镜、外科手术和病理等方面资料。结果　早、中期胃癌临床表现无特征性 ,男女之比为 2 .41∶1,以 61～ 70岁最多 ,胃窦是其好发部位 ,病理组织学以管状腺癌为多 ,胃镜误诊率是 12 .86%,淋巴转移率是 2 5 .3 3 %。结论　早、中期胃癌有明显的好发年龄和好发部位 ,以管状腺癌为多 ,胃镜误诊的主要原因是不能鉴别病变的良、恶性和准确判断病变量 ,影响淋巴转移的因素是浸润深度、广度、肿瘤大小和年龄 ,而与性别、组织学的分化程度无明显关系。

部分性脾栓塞术的临床应用：——附37例报告

应用部分脾栓塞术(PSE)治疗难治性原发性血小板减少性紫癜27例,血栓性血小板减少性紫癜1例;难治性再生障碍性贫血2例;Evan's 综合症2例;系统性红斑狼疮合并血小板减少性紫癜2例;继发性脾亢3例.获完全缓解者24例(64.9%);部分缓解者8例(21.6%),总有效率为86.S%.24例获完全缓解者18例追踪1年,6例复发,复发率为33.3%.与25例切脾对照组及文献报道比较,差异无显著性(P>0.05).本文对 PSE 术后外周血小板的变化进行讨论,并与脾切除作了对比。本文还对血小板破坏场、栓塞范围和方法等影响疗效的因素进行了探讨.作者认为 PSE 术可作为脾切除的替代术.     

慢性粒细胞白血病100例骨髓组织病理学Hannover分类法意义探讨

本文对100例慢性粒细胞白血病(CML)患者进行组织病理学研究,应用Hannover国际分类法进行分类,观察到骨髓组织病理学中巨核细胞增多者临床症状较重,中位生存时间较短,认为该分类法对临床及预后判断有指导意义,比既往应用的Bartl及Frisch分类法优越。     

包裹胰岛微囊的物理性能研究

用３％海藻酸钠及２．２％ＣａＣｌ＿２所制备的微囊在高流速及高浓度的蔗糖溶液冲击下未见破裂，且微囊包裹活细胞经过二小时的剧烈搅拌，亦无损漏。改进法所制备的微囊具有良好的机械强度，其物理性能已达到临床进行包膜胰岛移植治疗糖尿病的要求。     

Influence of caseload and surgical speciality on outcome following surgery for colorectal cancer: a review of evidence Part 2: Long-term outcome

OBJECTIVE: We reviewed recent literature to assess the impact of hospital caseload, surgeon's caseload and education on long-term outcome following colorectal cancer surgery. METHOD: We searched the MEDLINE and Cochrane Library databases for relevant literature starting from 1992. We selected hospital caseload, surgeon's caseload and surgeon's education, type of hospital, and surgeon's experience as variables of interest. Measures of outcome were recurrence-free survival and overall survival, and for rectal cancer frequency of permanent stoma. We reviewed the 34 studies according to tumour location: colonic cancer, rectal cancer, or colorectal cancer. We described the studies individually and performed a meta-analysis whenever it was considered appropriate. RESULTS: For colonic cancer, overall survival improved with increasing hospital caseload, odds ratio (OR) 1.22 [95% confidence interval (CI) 1.16-1.28], and surgeon's education. For rectal cancer, overall survival improved with increasing hospital caseload, OR 1.38 (95% CI 1.19-1.60), and, possibly by surgeon' education and experience. Cancer-free survival was strongly influenced by surgeon's education. The colostomy rate was less in high caseload hospitals, OR 0.76 (95% CI 0.68-0.85). For colorectal cancer, overall survival improved with surgeon's education. CONCLUSION: The data have provided evidence that long-term survival following colorectal cancer surgery in general improved significantly with increasing hospital caseload and surgeon's education.
