人碱性成纤维细胞生长因子基因在大肠杆菌中的克隆与表达

应用DNA重组技术将编码人碱性成纤维细胞生长因子（bbFGF）的基因克隆至原核高效表达质粒pBV_(221)的启动子下游。SDS-SAGE、ELISA和NTT活性监测结果表明:该重组质粒pBV-hbFGF在大肠杆菌DH5α中,经42℃诱导后,可表达出有较高生物活性的hbFGF。     

Inhibitory effect of tritoqualine on activation of latent polymorphonuclear leukocyte collagenase

Treatment of rats with histamine releaser compound 48/80 caused changes in blood leukocyte populations. An increased number of PMN-leukocytes was observed. Tritoqualine only modestly reduced the number of granulocytes. In animals treated with compound 48/80 an activation of PMN-leukocyte latent collagenase of up to 80% was observed. This activation was partially inhibited (about 40%) in animals pretreated with tritoqualine. The results presented suggest that the beneficial effect of tritoqualine in allergic diseases may be in part connected with an indirect inhibition of collagenase activity.     

Gangliosides in neurological pharmacotherapy.]

Gangliosides take part in synaptic transmission, neuronal metabolism and development of nervous tissue. They cooperate with nerve growth factor (NGF) and have positive influence on regeneration of the nervous system impairments. There exist many behavioural and biochemical evidences of gangliosides participation in the regeneration of experimentally injured animal nervous system. The therapeutic effectivity of gangliosides in clinical practice is encouraging. Commercial preparates of gangliosides (Cronassial, Sygen) have been successfully used in the therapy of chronic neuropathies, strokes and subarachnoidal haemorrhages. Among the adverse reactions to these drugs are: local irritation, anxiety and possible detrimental effect in immunological system. Ganglioside preparations need further clinical examinations.     

直视下经尿道内切开术治疗尿道狭窄

目的：探讨直视下经尿道内次切开术治疗尿道狭窄的有效性和安全性。方法：总结直视下经尿道内切开术治疗68例尿道狭窄和闭锁患者的疗效和经验，63例1次手术成功；3例行2次、2例行3次成功。结果：68例中，57例术后随访3～71个月，平均28．3个月，43例(75％)均排尿通畅；2例暂时性尿失禁者分别于术后3～6月内恢复。结论：直视下经尿道内切开术创伤小，并发症少，疗效确切，是尿道狭窄和闭锁的首选治疗方法。     

硫酸镁联合亚低温治疗对大鼠局灶性脑缺血的保护作用

目的　探讨硫酸镁对SD大鼠局灶性脑缺血损伤的保护作用。方法　将 4 0只大鼠随机分成模型对照组、硫酸镁治疗组、亚低温治疗组、硫酸镁联合亚低温治疗组。采用线栓法建立大鼠局灶性脑缺血模型。通过计算大鼠神经功能缺陷评分 ,测量脑梗死体积 ,观察神经元超微结构改变 ,评定硫酸镁联合亚低温治疗作用。结果各治疗组大鼠神经功能评分及脑梗死体积均显著低于对照组 (P <0 0 5 ) ,联合治疗组大鼠明显低于对照组 (P<0 0 1) ;联合治疗组神经元超微结构改变轻微。结论　硫酸镁联合亚低温治疗对大鼠局灶脑缺血有明显保护作用     

失血性休克复苏及监测指标研究进展

创伤、失血性休克是一古老的临床研究课题。不仅在平时常见，更重要的是与战伤救治密切相关。尽管近10年来取得了一些进展，但复苏时机、复苏目标、液体种类的选择、复苏后继续生命支持以及监测技术等仍是临床以及研究人员面临的重大挑战。本文将就近年来有关上述问题的最新研究进展进行分析和讨论，以期提高对该复杂综合征的认识，为今后的研究提供帮助。
