痧病的诊治体会

痧病在中医院校的教科书上并无专门的论述,而在春夏之季的农村则尤为常见。痧病有其临床表现特征,在治疗上也有许多简、便、验、廉且易行的方法。笔者在农村从事医疗工作多年,深感有必要对此加以研究或整理,使人们有一正确的认识。兹就痧病的诊疗谈谈个人的一点体会。1典型病例案1:刘某,男,24岁,学生,1997年7月25日初诊。因身重、肢体酸痛、胸闷1周而求诊。1周前因劳动时淋“毛毛雨”,感觉乏力,身重,全身肌肉酸痛,胸闷,饮食不振,纳谷乏味,微恶风寒,头胀痛,头重,颈项不适,大小便正常。前医诊为“风寒湿型感冒”,应用西药速效伤风胶囊及中药荆…     

Stimulation of tumor growthin vitro andin vivo by suramin on the VX2 model

Suramin is an antitrypanosomal compound with confirmed efficacy against several human malignancies. It is generally assumed that its mechanism of action includes the interaction with different growth factors, unlike most of the anticancer drugs. Its anticancer activity has not been testedin vivo against squamous cell carcinoma. The purpose of this study was to assess the efficacy and toxicity of suraminin vivo andin vitro on the VX2 tumor model at therapeutic monitored plasma concentrations. We determined the pharmacokinetics of suramin in rabbits, and modelized its administration in order to obtain plasma concentrations between 150 and 300 μg/ml throughout the treatment course of 3 weeks. Under these conditions, antitumor effects of suramin were evaluatedin vivo by comparing liver tumor involvement in suramin-treated and control rabbits. Liver involvement was quantified by image analysis andin vitro effects were also determined at the same concentrations.In vivo, suramin promoted liver tumor growth significantly (p<0.05), compared to untreated controls.In vitro, suramin significantly stimulated tumor cell growth at concentrations above 200 μg/ml (p<0.01). Suramin may have stimulatory effects on tumor growth in squamous cell carcinoma at relevant plasma drug concentrations. Caution should be taken in further trials in patients with squamous cell carcinomas.     

复式脉冲低能量ESWL治疗肾结石769例报告

目的探讨复式脉冲HB-V型低能量体外冲击波碎石机治疗肾结石的治疗效果.方法采用复式脉冲HB-ESWL-VG型低能量碎石机治疗直径<2.0 cm的各类肾结石769例，治疗工作电压3～9 kV，平均冲击次数2 300次.结果肾盏结石总粉碎率为97.4%，其中上中盏结石复打率为13.1%，术后3个月排净率为89.4%，下盏结石复打率为17.3%，排净率为81.5%；肾盂结石粉碎率为98.3%，复打率为6.1%，术后3个月排净率为93.0%.结论复式脉冲低能量ESWL治疗肾结石具有治疗成功率高、复打率低、无严重并发症、副作用少之优点.     

茶碱和双丁酰-cAMP对巨噬细胞水解酶影响的细胞化学观察

本文通过细胞体外培养,细胞化学定量分析等方法,观察了茶碱和双丁酰-cAMP对C_(57)BL/6J小鼠腹腔巨噬细胞酸性磷酸酶、α-醋酸萘酚酯酶的作用和影响.卡介苗活化的巨噬细胞与固有巨噬细胞相比,其酸性磷酸酶、α-醋酸萘酚酯酶活性明显升高.卡介苗活化的巨噬细胞在茶碱或双丁酰-cAMP作用下。酸性磷酸酶、α-醋酸萘酚酯酶活性明显受到抑制.茶碱或双丁酰-cAMP对固有巨噬细胞的酸性磷酸酶、α-醋酸萘酚酯酶无抑制作用.     

围手术期肠外营养支持在胃癌根治术的应用

1986～1988年的胃癌扩大根治术221例及根治性全胃切除术19例非肠外营养(N-TPN)支持为对照组,与1991～1993年的198例及61例施行TPN治疗为实验组进行对比。N-TPN组术后并发症总发生率为7.2％,TPN组则为2.0％;全胃切除术并发症发生率分别为31.6％和4.9％(P<0.01)。吻合口瘘发生率N-TPN组分别为2.7％和10.5％,而TPN组则均为0.0％(P<0.01)。膈下脓肿发生率N-TPN组为31.6％和15.8％,而TPN组则为1.5％和3.3％(P<0.05)。但本研究是回顾性的,所以要有待进行前瞻性的、对照的、随机的大范围研究。

Surgical Management of PICA Aneurysm and Incidental Facial Nerve Schwannoma: Case Report.

We report a patient with a posterior inferior cerebellar artery (PICA) aneurysm and an incidental facial nerve schwannoma at the cerebellopontine angle (CPA). A 46-year-old woman presented with the sudden onset of a severe headache, nausea, and vomiting. She had no other abnormal neurological symptoms and signs. Computed tomography (CT) showed hemorrhage in the fourth ventricle. Cerebral angiography demonstrated an aneurysm arising from the tonsillomedullary segment of the left PICA. A facial nerve schwannoma was incidentally found as the aneurysm was being clipped. The aneurysm was clipped via a left transcondylar approach. Subsequently, the schwannoma (2 x 3 x 2 mm) was resected from the facial nerve fascicles, and the facial nerve was preserved. Postoperatively, the patient developed mild to moderate dysfunction of the facial nerve (House-Brackmann grade III [H-B III]) but her hearing was intact. Both a facial nerve schwannoma involving the CPA and an aneurysm involving the PICA can be managed through the transcondylar approach. An asymptomatic facial nerve schwannoma can be resected safely with minimal facial nerve dysfunction.
