乳头溢液的外科治疗（附207例分析）

目的探讨乳头溢液的渗断和治疗方法，为合理的治疗提供科学依据。方法回顾分析手术治疗的207例乳头溢液病例资料。结果（1）在非哺乳期间发生乳头溢液多属病理性溢液；（2）通过美蓝法或平针头指示法行区段切除术，安全准确。结论（1）乳头溢液特别足血性溢液应手术治疗．对早期发现和早期治疗乳腺癌有鼋要的临床意义。（2）乳头溢液伴肿块者，不沧年龄大小、溢液性质均应手术治疗。     

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。     

小脑后下动脉动脉瘤的诊断和治疗

目的探讨小脑后下动脉动脉瘤的临床特征、诊断、鉴别诊断和治疗。方法回顾性分析12例小脑后下动脉瘤的临床表现、影像学特征、手术效果及诊治过程中存在的相关问题。结果12例中有11例因动脉瘤破裂出血而发病,单纯第四脑室出血4例,全脑室系统出血2例,小脑半球出血3例,小脑蚓部伴第四脑室出血1例,侧脑室伴第三脑室出血1例,以后颅窝占位病变表现1例。8例术前行DSA检查明确诊断,4例术中明确诊断。12例均行后颅窝开颅显微手术治疗,其中动脉瘤颈夹闭9例,孤立切除2例,动脉瘤加固术1例,术后2例因脑积水加重行脑室-腹腔分流术。12例中除1例术后留有轻偏瘫外,其余11例恢复良好。结论小脑后下动脉瘤多以第四脑室出血发病,少数以小脑半球或蚓部出血发病,及早治疗效果满意。手术方式应尽量夹闭动脉瘤颈,对于小脑后下动脉末端动脉瘤,可以采用孤立切除术。     

西咪替丁对林可霉素生物利用度的影响

通过8名健康志愿者服药后的对照实验,用微生物法检测血药浓度,按一室模型配置求算药物动力学参数,探讨西咪替丁对林可霉素体内过程的影响。结果表明,西咪替丁不能改变林可霉素的吸收速率(Ka)和消除速率(Ke),但可通过增加其吸收程度或改变其分布容积,使林可霉素的血药浓度和生物利用度分别增加约19％和27％。

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.     

入世的平和——托马斯博士与庄子

“天地与我并生，而万物与我为一”，以客观的说法来看，恰恰是一种朴素的唯物主义，即融入人类所生存的自然环境，以天地万物的本相和规则去生活，不是一味强调征服和超越。
