Pericatheter urethrography and its use in post interlocking sound urethroplasty]

21 cases of posterior urethral rupture due to pelvic fracture were treated by acute interlocking sound urethroplasty since 1982. Postoperative pericatheter urethrography was carried out to observe the recover of urethral rupture. The results showed that the time for recover of ruptured urethra varied from 4 to 13 weeks. 71% of all cases required more than 8 weeks for recovery. The patients were followed up from 1 to 9 years, and 86% of them showed satisfactory results. It is believed that pericatheter urethrography not only provides an objective proof for the recovery of ruptured urethra but also can be used as a reliable basis for the removal of stenting catheter.     

短暂性脑缺血发作患者血浆中TXB2和PGF1α含量检测

本文用放射免疫法测定47例短暂性脑缺血发作(TIA)患者血浆中血栓素B_2(TXB_2)和6酮-前列腺F_(1α)(PGF_(1α))的含量。结果发现TIA患者血浆中TXB_2含量增高,PGF_(1α)降低;头颅CT或MRI示有小灶性梗塞者及TIA发作持续时间长于30min者TXB_2升高和PGF_(1α)降低更显著。治疗3个月后,血浆PGF_(1α)显著增高。TXB_2和PGF_(1α)在体内的失平衡是急性脑血管疾病发病的重要机理之一。     

舒必利治疗精神分裂症患者脑脊液HVA含量的对照研究

为了探讨精神分裂症患者治疗期间多巴胺的变化,我们选择舒必利治疗组20例,非舒必利治疗组10例作为病例组;15例非精神病患者作为对照组;检测脑脊液中多巴胺代谢产物高香草酸的含量;结果显示两组无显著性差异。精神分裂症患者治疗后舒必利组高香草酸含量升高,非舒必利组则降低,进一步分析显示舒必利治疗组非显效者较显效者治疗后高香草酸显著升高。提示机体对药物阻滞多巴胺受体后代偿反应的强弱与疗效有一定关系。     

五型病毒性肝炎的暴露因素与临床表现的比较

比较急性病毒性肝炎患者感染打危险因素，同时比较五型肝炎的症状和体征。连续收集急性病毒性肝炎患者血清２９３份，用ＥＬＩＳＡ法检测了五型肝炎病毒的病原学指标，并进行了流赞美同学调查。暴露因素：丙肝的肠道外暴露外明显多于甲肝；甲肝和戊肝有较高的“甲肝”患者接触史；乙肝，丙肝和丁肝有高的“乙肝”接触史，与甲肝，戊肝相比差异显著。     

Clinical observation of Qi deficiency syndrome in 72 patients with chronic obstructive pulmonary disease treated with Yiqi Mianyi Granule

Seventy-two patients of chronic obstructive pulmonary disease (COPD) of Qi deficiency syndrome with abnormal immune indices were treated with Yiqi Mianyi Granule (YQMYG) and the efficacy was compared with that of 30 cases treated with Zhenqi fuzheng Granule (ZQFZG) for control. Results showed that the markedly effective rate of symptomatic improvement of Qi deficiency in YQMYG group was 65.3%, the total effective rate 93.1%. 88.6% of the immune indices lower than normal were corrected and 43. 7% of them were normalized, while for indices that were higher than normal the rate were 78.2% and 52.9% respectively. These results suggested that YQMYG could improve symptom of Qi Deficiency markedly, strengthen cellular immunity and regulate immune dysfunction. Its therapeutic efficacy was obviously superior to ZQFZG (P<0.Q5).

微机判断血气的程序设计和临床应用

将肺心病、慢性肾炎等338例次的血气分析结果输入计算机,应用我们设计的多结果血气判断微机程序判断酸碱紊乱状态,其结果与人工综合判断结果完全相符。而单结果计算机判断和单纯人工判断的结果与人工综合判断结果的符合率分别为88.2％和87.3％。表明多结果计算机判断程序能有效地避免误判、漏判。     

负载型丝光沸石催化剂的催化性能研究

运用二元碱氮置换吸附红外光谱法、分子筛孔径分布测定技术、XPS技术,考察了丝光沸石表面酸性与孔结构的相互关系、钯在丝光沸石上分布情况和价态及其与沸石的相互作用。结果表明,随着丝光沸石脱铝程度的增加,表面出现大量不规整晶格,存在较多的次级孔道。强质子酸中心主要分布在它的“外表面”。钯在其表面富集,并与“外表面”上的质子酸中心协同作用,促进了轻质烷烃异构化反应。     

油页岩及其矿渣的致突变研究

采用Ames试验、E Coli大肠杆菌突变试验和动物骨髓细胞微核试验对油页岩及其矿渣提取物进行了致突变性鉴定。结果表明油页岩及其矿渣提取物在微核试验中呈阳性反应,而在细菌回变试验中呈阴性反应。     

肝硬化患者胰岛素释放试验的临床意义

本文报道46例肝硬化患者口服葡萄糖胰岛素释放试验的结果,并与18名正常人和18名原发性糖尿病患者比较。肝硬化患者糖耐量减低者28例(60.9％),其中29例(43.5％)呈糖尿病型耐量曲线。胰岛素释放高峰值在服糖后2h;释放过多和分泌延迟者32例(69.6％),降低者4例(8.7％)。20例肝源性糖尿病患者的胰岛素释放指数明显高于原发性糖尿患者。笔者认为血浆胰岛素和胰岛素释放指数测定对鉴别这两种类型的糖尿病有很大价值。
