高职教育实训基地建设的探索与实践

以江西现代职业技术学院为例,提出高职教育实习基地建设的基本构想。在实践中应充分利用现有资源,营造真实的职业环境;加大投资力度,建立校内实训中心;建设相对稳定的校外实训基地。在管理中要健全以实训中心为核心的基地管理模式,加强“双师型”实训教师队伍建设和实训教学的教材建设,将职业道德教育融入教育过程中。

Cardioprotective activity of synthetic guggulsterone (E and Z-isomers) in isoproterenol induced myocardial ischemia in rats: A comparative study

Guggulsterone, a mixture of cis (E) and trans (Z) isomers (7∶3 w/w) was synthesized from 16-DPA. The isomers were separated by column chromatography and evaluated for cardioprotective and antioxidant activities. Myocardial necrosis induced by isoproterenol in rats caused marked increase in serum creatine phosphokinase and glutamate pyruvate transaminase. Simultaneously in ischemic heart, phospholipase, xanthine oxidase and lipid peroxides were enhanced following depletion of glycogen, phospholipids and cholesterol. Treatment with guggulsterone and its both isomers at the dose of 50 mg/kg po., significantly protected cardiac damage as assessed by the reversal of blood and heart biochemical parameters in ischemic rats. The cardioprotective activity of guggulsterone and of both the isomers were compared with that of gemfibrozil at the same doses. Guggulsterone and both the isomers at tested concentrations (5–20mM) inhibited oxidative degradation of lipids in human low-density lipoprotein and rat liver microsomes induced by metal ionsin vitro. The drug counteracted against the generation of superoxide anions (O₂) and hydroxyl radicals (OH⁻) in non-enzymic test systems. It is suggested that cardioprotective and antioxidant activities of synthetic guggulsterone and guggulsterone obtained from gum resinCommiphora mukul that contains isomers E & Z in the ratio of 46∶54w/w are the same.     

Acrosin activity in spermatozoa of infertile Nigerian males

The objective of this study was to evaluate acrosin activity in spermatozoa of infertile Nigerian men and to compare with those of the fertile men. The acrosin activity was evaluated using the Acroscreen reagent kit. The acrosin activity of the fertile men was 40.7±5.2 mIU/10⁶ sperm (range 30.1–51.3) and those of the infertile men was 22.4±8.33 mIU/10⁶ sperm (range 5.7–39.1). The difference in the mean was statistically significant (P<0.001). There was a subpopulation of the infertile men who had their acrosin activity within normal range of the fertile men, 32.9±1.57 mIU/10⁶ sperm. But the difference in the mean was statistically significant (P<0.001). Acrosin activity decreased with increased morphological changes in the spermatozoa. It is concluded that acrosin activity in the infertile Nigerian men is significantly lower than that in the fertile men. Acrosin activity may also be affected by morphological changes in the spermatozoa.     

不同品系小鼠自发活动特点及中枢抑制药新评价模型

目的用开场实验研究NIH、ICR、昆明种小鼠自发活动特点,并以戊巴比妥为工具药建立药物中枢抑制作用新的评价模型.方法用开场实验观察小鼠进入新环境的自发活动特点,并用计算机图像处理系统记录,分析小鼠30 min内的活动轨迹,观察不同时间段的总路程、中央逗留时间、中央路程3个参数.还观察了腹腔注射不同剂量戊巴比妥对自发活动特点的影响.结果各种小鼠总路程在前10 min明显大于后20 min (P < 0.001) ;中央逗留时间和中央路程变化较小,但存在一定的品系和昼夜差异.戊巴比妥可减少ICR和NIH小鼠(昆明种小鼠无效)的总路程,但无典型的量效关系;但可剂量依赖性减少各种小鼠中央逗留时间和中央路程(P < 0.01).结论本实验建立的方法能反映小鼠自发活动特点,并可用于评价中枢抑制药作用,其中中央逗留时间和中央路程是稳定、敏感的指标.     

浅析中共早期对委员会制的探索(1921-1935)

委员会制是中国共产党领导体制的重要内容。中共早期对委员会制的实践探索充分说明了真正的委员会制既要反对个人专权,也要反对权力分散。要做到这两点,一方面要有完备精良的干部队伍;另一方面要有从委员会的产生到运作形成一套完善的制度体系。但是囿于所处的残酷的斗争环境,中共早期无论是干部队伍还是配套制度都存在诸多不足。
