胃粘膜癌前病变的形态定量研究——胃粘膜核腺比值的定量分析

应用自动化图象分析仪对131个胃粘膜肠型病灶(单纯性肠化27个;异型增生:轻度30,中度35个,重度20个;肠型胃癌19个)进行定量分析。以单个腺管内细胞核总面积与细胞面积之比(ING)作为反映细胞核大小、数量及覆层排列程度的客观定量指标。结果发现:单纯性肠化(对照组)0.165±0.025,轻度异型增生0.21±0.023,中度异型增生0.259±0.026,重度异型增生0.32±0.028,分化型胃癌0.371±0.052,各组ING值呈正态,各组间的均值有非常显著的差异(P<0001)。因而,ING可作为胃粘膜癌前病变诊断的指标。     

鼻内镜联合显微镜经鼻腔蝶窦及中颅窝手术

目的探讨鼻内镜下经鼻腔直接入路行蝶窦及中颅窝手术的方法. 方法鼻内镜下经较宽大一侧鼻腔将中鼻甲向外推移,鼻腔扩张器扩大视野,直达并开放蝶窦前壁, 鼻内镜与显微镜联合切除病变. 结果 10例孤立性蝶窦炎术后症状消失.6例蝶窦囊肿、脑膜瘤均一次手术切除.32例垂体腺瘤17例全切除,12例次全切除,3例大部分切除,术后补充X刀治疗.48例术后随访6个月～3.5年,平均2.5年,蝶窦囊肿、蝶窦炎、脑膜瘤无复发,3例垂体腺瘤复发,无颅内感染并发症,无鼻腔粘连、鼻出血等鼻腔并发症. 结论鼻内镜联合显微镜经鼻腔蝶窦及中颅窝手术损伤小、出血少、手术时间短、效果好.     

残胃癌临床诊治分析

目的分析和总结残胃癌的外科诊断、治疗及预后情况。方法对1990年以来收治的35例残胃癌的发病率、临床表现、治疗情况和预后进行回顾性分析。结果首次胃切除以胃溃疡为主,占65.7%,首次手术BillrothⅡ式占82.9%(29/35)。残胃癌早期缺乏特异的症状,主要为上腹部隐痛不适,首次手术距临床诊断残胃癌的间隔时间平均为16.3年。本组残胃癌手术切除率及根治性切除率分别为77.1%和54.3%,根治性切除患者1、3、5年生存率分为78.9%、52.6%、36.8%,Ⅰ期、Ⅱ期患者的5年生存率为72.7%。结论胃良性病行手术治疗时以BillrothⅠ式为首选,定期胃镜检查是早期诊断残胃癌的关键,根治性切除是治疗残胃癌的有效方法及影响残胃癌预后的重要因素。     

中、晚期肝癌并发脾功能亢进的介入治疗

目的 探讨肝癌介入治疗与部分脾动脉栓塞同时进行的疗效。方法 对18倒不能手术切除且经B超或CT确诊，脾肿大并有WBC、PLT明显低于正常的肝癌患者行PSE TACE或经导管肝动脉化疗(TAI)介入治疗，记录治疗前后WBC、PLT、甲胎蛋白(AFP)数值进行分析。结果 栓塞后3天、7天、60天WBC、PLT值明显升高，AFP值明显下降，临床症状明显改善。结论 PSE TAI或TACE治疗肝癌并脾功亢进是一种行之有效的办法。     

Nerve growth factor and tyrosine kinase A in human salivary adenoid cystic carcinoma: expression patterns and effects on in vitro invasive behavior.

PURPOSE: Perineural invasion is a frequent occurrence in salivary adenoid cystic carcinoma (ACC) and may prevent complete surgical resection. Studies have indicated that nerve growth factor (NGF) and its high-affinity receptor tyrosine kinase A (TrkA) may play a role in perineural invasion in several malignancies in which perineural invasion is observed. The present study was conducted to investigate the expression of NGF and TrkA in salivary ACC and to examine the effects of NGF on adhesion, migration and invasion capacities of a salivary ACC cell line (SACC-83) in vitro. PATIENTS AND METHODS: Expression of NGF and TrkA was explored using immunohistochemistry in paraffin-embedded tissues of 32 cases of salivary ACC. The effects of NGF on in vitro adhesion, migration, and invasion capacities of the SACC-83 cell line were examined using an MTT assay and a modified Boyden chamber assay respectively. RESULTS: In ACC specimens, 31 (96.9%) and 32 (100%) tumors showed immunoreactivity for NGF and TrkA respectively. Significant correlations were found between NGF/TrkA expression levels and perineural invasion (P < .05). In cell adhesion assay, the percent adherences of SACC-83 cells co-cultured with 25 ng/ml NGF at 1.5 hours and 5, 25 ng/ml NGF at 6 hours were significantly higher than that co-cultured with 0 ng/ml NGF (P < .05). However, high concentration of NGF (500 ng/ml) resulted in a significant inhibition of invasion (P < .05). CONCLUSION: Overexpression of NGF and TrkA in human salivary ACC tissues may constitute a reason for perineural invasion in salivary ACC.
