纤维支气管镜胸膜腔检查对原因不明胸腔积液的诊断价值

为评价纤维支所管镜行胸膜检查在诊断原因不明胸腔积液中的价值，用纤维支气管镜对１０例原因不明的胸腔积液患者进行胸腔检查。结果９例２检查后明确了病因，且无并发症，提示该法对于不明胸腔积液的诊断是一种阳性率高、安全、简便的检查方法。     

复方18甲基炔诺酮透皮控释传递系统的LNG人体药物动力学与药效学评价

复方18甲基炔诺酮/雌二醇透皮控释传递系统(LNG/E_2 TCDS)能同时恒速释放低剂量的LNG和E_2,在1周内维持一个平稳而有效的LNG血药浓度。药动学与药效学研究证明,该系统释放的LNG能达到血清LNG目标水平,产生有效的排卵抑制(6/6)。LNG/E_2 TCDS可望发展成为一种安全、有效、非侵入性的新型生育调节避孕制剂。     

斑点—酶联免疫吸附试验检测卡氏肺孢子虫

应用完整的卡氏肺孢子虫包囊作抗原，以４×１０＾７／ｍｌ包裹点样，作斑点－酶联免疫吸附试验检测肺印片卡氏肺孢子虫包囊阳性的ＢＡＬＢ／ｃ小鼠血清２０份，同时检测包囊阴性的小鼠血清２０份，结果除一份小鼠血清ＩｇＧ阴性反应外，均为阳性反应，阳性率为９５％；而正常对照血清全为阴性反应。另外，检测了３份纤支镜刷检物中包囊阳性的病人血清，均为阳性反应；５０例健康孕妇血清的检查，抗体阳性率为１２％。     

红霉素对犬幽门括约肌压力影响及其与胃动素,生长抑素的关系

为探讨红霉素对犬幽门括约肌的作用及其机理，及其与血浆胃动素，生长抑素的关系。方法采用胃压力测量仪及放射免疫法，同步监测观察了１０条犬静脉滴ＥＭ前后和使用拮抗剂后的幽门压力、血浆ＭＴＬ，ＳＳ的变化，结论：ＥＭ具有增高犬胃幽门压力的作用，其作用机理除与血浆ＭＴＬ有着密切的关系外，血浆ＳＳ也可能共同参与了其调节机制。     

Role of granulocyte colony-stimulating factor as adjunct therapy for septicemia in children with acute leukemia

The granulocyte colony-stimulating factor (G-CSF) has been shown to accelerate recovery from severe neutropenia and to decrease the incidence of documented infections after intensive chemotherapy in cancer patients. However, the routine prophylactic use of G-CSF is expensive. This study was conducted to determine the role of G-CSF as adjunct therapy for septicemia following neutropenia caused by chemotherapy in children with acute leukemia. Fifty consecutive episodes of septicemia were studied involving 34 episodes of Gram-negative, 7 episodes of Gram-positive, 5 episodes of polymicrobial bacterial septicemia, one episode of fungemia, and 3 episodes of disseminated fungal infection. In the first 25 episodes, G-CSF was not used (group A). For the next 16 episodes, G-CSF 200 μg per square meter per day subcutaneously was given immediately after the septicemia was documented until the absolute neutrophil count was maintained at more than 1,500 per cubic millimeter (group B). Thereafter, G-CSF at the same dose as that of group B was prophylactically used in all the children who received high-dose cytosine arablnc-side-containing regimens. Nine episodes of septicemia occurred (group C). The incidences of mortality per episode of septicemia in groups A, B, and C were 12.0% (3/25), 12.5% (2/16) and 0% (0/9), respectively. Statistically, there was no difference between the three groups overall and in pair-wise comparisons (all P > 0.5). The durations of G-CSF administration in group B ranged from 6 to 26 days with a median of 12 days and the durations of G-CSF administration in group C ranged from 10 to 23 days with a median of 19 days. With or without G-CSF, there may be no significant difference in the mortality of septicemia following neutropenia caused by chemotherapy in children with acute leukemia.     

单用体外震波碎石治疗尿路结石的体会

本文报道1988年6月～11月,单独应用上海交通大学电力工程系研制的JT—ESWL—Ⅱ型体外震波碎石机,治疗尿路结石506例,其中肾结石304例(双侧12例)输尿管结石199例(双侧5例),膀胱结石3例。冲击能量15～40焦耳,每次治疗冲击波次数为400～2800次。本组无开放手术、无肾脏丧失、无死亡。效果满意者96.44％。其并发症主要有血尿、结石串。作者认为单用ESWL治疗小于3Cm的尿路结石安全可靠、无严重并发症。文中对单用体外震波碎石(ESWL)治疗尿路结石病例选择,如何减少并发症,提高治疗效果进行了讨论。     

左心室舒张(充盈)功能的影响因素

本文用X线电影摄影方法评价了49例左室舒张(充盈)功能的影响因素。冠心病(CAD)组23例,高血压病组12例,正常对照组14例。左室充盈功能或顺应性主要受冠脉病变严重程度的影响。冠脉狭窄程度越重,并有陈旧性心肌梗塞、室壁运动异常、EF下降,则充盈功能受损愈明显。血压、年龄因素对舒张充盈功能的影响较小。在CAD组中,心率与1/3充盈分数呈负相关,与正常化高峰充盈率(NPFR)不相关,而EF则与NPFR相关良好。
