对诊断PADAM的血清游离睾酮界限值的初探

目的探寻诊断中老年男子部分雄激素缺乏综合征(PADAM)血清游离睾酮(FT)的界限值。方法根据60例45岁以上健康男性完成伊斯坦布尔症状量表(ISS)与视听性刺激(AVSS)时阴茎勃起监测结果进行分组,计算AVSS勃起功能正常组推算的游离睾酮(CFT)值的参考范围。结果AVSS勃起功能正常组CFT的中位数为0．37(0．20～0．52)nmol/L,异常组的中位数为0．25(0．12～0．40)nmol/L,z=2．25,P＜0．05,差别有显著性意义。两组性功能症状的差别也有极显著性意义(P＜0．01)。CFT的界限值是0．20nmol/L。结论研究用ISS和AVSS勃起功能正常对象的血清FT值,可为诊断PADAM建立界限值。

Laryngeal tuberculosis: a review of 26 cases.

OBJECTIVES: To review the clinical characteristics of laryngeal tuberculosis. STUDY DESIGN: Retrospective case series. SUBJECTS AND METHODS: Medical records of 26 histopathology-confirmed cases in a tertiary medical center from 1992 to 2006. RESULTS: The female patients were significantly younger than male patients. Hoarseness is the most common symptom (84.6%) because true vocal fold is most commonly involved (80.8%). Infection usually involves unilateral (66.7%) and right-side larynx but multiple subsites of the larynx (57.7%). The appearance of the affected larynx may have mixed features and change before diagnosis. Laryngeal tuberculosis is usually misdiagnosed as laryngeal cancer, especially in patients with malignant signs such as enlarged cervical lymph nodes and vocal fold immobility. Chest film is better than sputum examinations for screening. CONCLUSION: We should be especially alert about TB infection when facing young female patients with unusual laryngeal lesions. Extensive laser excision before diagnosis should be avoided because after antituberculous treatment, prognosis is usually good and vocal fold immobility could be reversible.     

The characteristics of Hep-2 cell with multiple drug resistance induced by Taxol.

OBJECTIVE: To investigate the characteristics of Hep-2 cell with multidrug resistance (MDR) induced by Taxol. STUDY DESIGN: Hep-2 cells were exposed in stepwise escalating concentration of Taxol to develop the resistant cell line-Hep-2T. Cell cycle distribution, apoptosis, and rhodamine accumulation were studied through flow cytometry. The MDR1 and MRP1 genes were detected through real-time quantitative RT-PCR, and the corresponding proteins were detected through Western blotting. RESULTS: The drug resistance of Hep-2T cells to Taxol, doxorubicin, gemcitabine, 5-FU, and cisplatin all increased. The percentage of G0/G1 phase and the antiapoptosis ability increased significantly compared with Hep-2 cells. Both MDR1 and MRP1 also increased at gene and protein level, though MDR1 was more prominent. CONCLUSION: More emphasis should be laid on MDR1/Pgp, the non-Pgp substrate chemotherapeutic agents, and the changes of cell cycle distribution to prevent MDR induced by Taxol. SIGNIFICANCE: These findings may provide theoretical support for the reverse of MDR.     

复方麝香注射液联合脑血肿引流术治疗中老年高血压脑出血疗效观察及费用对比

目的:探讨复方麝香注射液联合微创手术治疗中老年高血压脑出血的临床疗效.方法:将78例接受微创治疗的患者随机分组,两组均采用内科综合治疗.手术对照组在综合治疗基础上加用微创手术进行脑血肿引流;中西医结合组在微创手术治疗后加用复方麝香注射液(10～20 ml/d)静脉滴注1周.结果:中西医结合组显效率(66.67%)、有效率(82.05%)均明显高于手术对照组(46.15%和69.23%,P均<0.05),存活患者日常生活能力也明显优于手术对照组(P<0.05),意识恢复时间明显短于手术对照组(P<0.05),并发症的发生率(15.38%)明显低于手术对照组(38.46%,P<0.01),病死率(5.13%)明显低于手术对照组(10.26%,P<0.01),平均住院天数[(18.29±4.93)d]明显少于手术对照组[(26.23±5.82)d,P<0.05],平均住院费用[(5 916.23±826.39)元]明显少于手术对照组[(8 168.35±1 021.21)元,P<0.05].结论:脑血肿引流术后加用复方麝香注射液治疗中老年高血压脑出血,可降低病死率,减少并发症,降低病残程度,提高生存患者的生活质量,缩短住院时间,降低治疗费用.

血管内氧合器的研制

为了探索呼吸辅助的新方法，我们采用国产聚丙烯中空纤维，自行设计、制造模具，研制出一种血管内氧合器。该氧合器是一个小的、细长的可经单侧股静脉或颈静脉切开，置入腔静脉内的装置。氧合器有效长度４０ｃｍ，膜交换面积０．０９ｍ＾２。经负压调节通过血管内氧合器的氧流量，以防止纤维破裂造成的血管内气栓的危险。一根双腔导气管使气体经同一静脉切开部位循环，气体经内芯管流经血管内氧合器尖端，然后经中空纤维束流出。目前     

El Tor型霍乱弧菌L型的某些生物学性状

本研究主要对El Tor型霍乱弧菌(Vibrio cholerae biotvpe eltor,EVC)L型的某些生物学特性如生化反应、抗生素敏感性及超微结构等进行了探讨.研究发现EVC不稳定L型的生化性状与EVC流行株的非常相似,而稳定L型则变化很大.抗生素敏感性试验显示EVC稳定L型对某些作用于细胞壁的抗生素的敏感性减弱,而对大多数作用于蛋白质合成的抗生素的敏感性增强.与流行株相比,EVC稳定L型和不稳定L型的超微结构的改变很明显.此外,本文还讨论了产生这些改变的可能机制.
