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％。

继发性肝癌的联合治疗

采用手术切除联合术后B超引导肝内门静脉区域化疗（简称PHPC）治疗胃肠道癌异时肝转移24例。随访4～54个月，结果：术后经3个疗程的PHPC，8例已存活肥18～48个月；13例分别经过2～11次的PHPC，已存活5～39p个月；另3例死亡。作者认为，对继发性肝癌采用手术切除配合术后B超引导的PHPC是一种延长患者生存期的有效联合治疗方案。     

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。     

在就诊患者和健康体检者中筛检人胃螺杆菌

目的：通过几种不同的检查方法调查人胃螺杆菌在人群中的感染情况及在慢性胃炎中的致病作用。方法：３８０例行消化道症状的就诊患者和４３２名健康体检者的胃粘膜活检标本分别行涂片、尿素酶试验、１４Ｃ－尿素呼吸试验和组织学检查。结果：人胃螺杆菌在上述两类人群中的感染率分别为２．１１％和１．１６％。涂片Ｇｒａｍ染色和切片ＷＳ银染是目前诊断该菌感染较理想的手段，不论有无症状，患者在组织学上均伴有慢性炎症改变，根据形态学特点该菌可大致分为两型，分别与某些动物胃内的螺旋菌相似。结论：人胃螺杆菌在人群中感染率较低，可能是一种源自动物的慢性胃炎相关性病原菌。     

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.     

血清Ⅲ型原胶原含量与肝纤维化的关系（附102例肝活检分析）

为进一步研究血清Ⅲ型原胶原（ＰＣⅢ）含量与肝纤维化的关系，对肝炎患者血清ＰＣⅢ含量与肝炎组织学变化进行对比分析．方法：用ＲＩＡ法测定６１６例急、慢性肝炎及肝硬化患者的血清ＰＣⅢ含量，其中１０２例同时做肝活检，按照Ｋｎｏｄｅｌｌ肝组织炎症活动性指数标准记分．结果：急、慢性肝炎及肝硬化患者血清ＰＣⅢ含量明显高于正常人，差异有显著性（Ｐ＜ｏ．０５～０．０１）．其升高的血清ＰＣⅢ含量与肝细胞坏死范围及门管区炎症程度无相关性（ｒ＝０．４９４，Ｐ＞０．０５），而与肝纤维化程度呈正相关（ｒ＝０．６６８，Ｐ＜０．０１）．结论：血清ＰＣⅢ测定是判断慢性肝炎及肝硬化时肝纤维化程度的有用指标．
