苦参素治疗老年性慢性丙型肝炎伴合并症临床分析

目的观察苦参素治疗老年性慢性丙型肝炎合并高血压、糖尿病、白细胞减少及65岁以上患者的效果。方法治疗组给予苦参素600mg,每日静点1次。对照组给予一般保肝药,疗程3个月。结果治疗结束时,治疗组ALT复常率94.9%,对照组36.8%,2组显著差异(P<0.05),HCVRNA治疗组转阴55.6%,对照组5.3%,2组显著差异(P<0.01)。结论苦参素是老年性慢性丙型肝炎伴合并症状患者的新希望。     

15例胃间质瘤临床病理分析

近年来，许多学者通过免疫组化及超微结构对胃肠间质瘤（gastrointestinal stromal tumor，GIST）进行研究。我院近8年来收治15例胃间质瘤，现将其临床病理特点分析报告如下。     

Gaucher disease: abdominal MR imaging findings in 46 patients.

Abdominal magnetic resonance imaging findings were reviewed in 46 patients with Gaucher disease. All patients had hepatosplenomegaly at the time of initial imaging. Splenic nodules were present in 14 patients (30%) and varied in signal intensity. These nodules were isointense on T1-weighted and hypointense on T2-weighted images. Splenic infarcts were seen in 15 patients (33%), and four of these patients (9%) also had subcapsular fluid collections. Both nodules and infarcts were present in the spleen in four patients (9%). Pathologic correlation was performed with specimens from two patients who underwent partial splenectomy. Focal areas of abnormal signal intensity were noted in the liver in nine patients (20%). They were either stellate or segmental, and may represent fibrotic septa with ischemic changes associated with aggregates of Gaucher cells. No changes were noted in the kidneys or abdominal lymph nodes.     

Outcome study: comparison of short-term vs long-term treatment in a residential community.

All patients admitted to a Residential Treatment Center (RTC), a drug-free hospital-based inpatient facility in February 1985 through July 1985, were followed-up 6 months after discharge. The results are contrasted with those obtained in 1973 in a similar follow-up study. Length of stay at RTC had been reduced from 1 year in 1973 to 3 months in 1985. Six months after discharge, the longer length of stay in 1973 appears to be almost twice as effective as the 3-month program in 1985.     

急非淋白血病完全缓解后巩固治疗的对照研究

目的探讨急非淋白血病完全缓解后巩固治疗与缓解期的关系。方法对３０例坚持与未坚持完全缓解后巩固化疗的急非淋患者（每组１５例）进行对照研究。比较两组患者的完全缓解期。结果两组患者入院时情况、治疗及达完全缓解时间经统计学处理无明显差异（Ｐ＞０．０５）；而坚持巩固化疗组平均持续完全缓解期（１９．８ｍｏ）明显长于对照组（８．４ｍｏ），统计学具有显著差异（Ｐ＜０．０１）。结论急非淋白血病达完全缓解后，坚持骨髓抑制性治疗对延长完全缓解期以达长期生存目的具有重要意义。     

APPLICATION OF ACUPOINT-INJECTION THERAPY TO PAIN SYNDROME: CLINICAL ANALYSIS OF 250 CASES

In this paper,250 cases of headache,shoulder pain,lumbago and leg pain weretreated with 20％Angelicae Sinensis mixed with Vitamine B_(12) point-injection therapy.The total effective rate was 95.2％and in which the cure rate was 53.6％.Authors have found a close correlation between the effectiveness and the duration of disease.     

Clinical and histological patterns of dermatofibromas of the nail apparatus

True fibromas develop as painless slow-growing nodular tumours. They may appear in any portion of the nail apparatus. The clinical features vary according to their anatomical site. In contrast, the histological features, consisting of a dermal hypocellular reticular nodule with ill-defined demarcation, were similar in all our patients, and factor XIIIa was negative.     

阶跃切应力对内皮细胞释放前列环素的影响

采用流室定量研究阶跃切应力对内皮细胞释放前列环素（ｐＧＩ＿２）的影响。对流室中的内皮细胞连续１００分钟施加１、１０、２０ｄｙｎｅ／ｃｍ￣２的阶跃剪切应力，用放免法测流室的８个时间段流出液的６－ｋｅｔｏ－ＰＧＦｉ＿（１ａ）。绘出切应力刺激内皮细胞释放ＰＧＩ＿２的曲线。结果表明：未施加切应力时，内皮细胞释放ＰＧＩ＿２的量在检测限以下，施加切应力后，ＰＧＩ＿２释放速率很快达极大值，且又在数分钟内减小．施加阶跃切应力越大，ＰＧＩ＿２释放速率曲线峰值越高，但衰减也越快，在８０～１００分钟时间内的前列环素释放速率平均值也越大。由此提示，在活体中血液流变学因素一血流切应力对血管内皮细胞释放前列环素有促进作用。
