中药专业实践教学改革与探索

针对目前中药专业毕业生实践动手能力有所下降的趋势,安徽中医学院修订中药专业实践教学计划,增加课程见习和社会实践等实践教学内容,改革毕业实习模式,加强对毕业实习的管理。通过一系列举措,毕业生的实践动手能力有所提高,取得了一定的成效。     

鱼腥草挥发油β-环糊精包合物的制备工艺研究

目的优选鱼腥草挥发油β-环糊精包合物制备最佳工艺条件,为其制剂的研究奠定基础.方法按正交表L9(34)安排试验,以挥发油保留率为指标,对影响饱和溶液法的4个因素进行考察.结果最佳包合工艺条件为,油-β-环糊精-水＝1∶8∶80(mL∶g∶mL),包合温度为40 ℃,搅拌1 h.结论按优选的工艺条件鱼腥草挥发油可与β-环糊精形成稳定的包合物,且挥发油保留率高.     

连建伟教授治疗病毒性肝炎经验介绍

连建伟教授治疗病毒性肝炎，认为尽管病毒性肝炎有甲、乙、丙、丁、戊等类型不同，但急性期和慢性活动期表现证候却相近似，治疗急性黄疸型肝炎、慢性肝炎活动期予以清热解毒，活血利湿；阴黄治以温中化湿退黄；慢性肝炎迁延期以健脾养肝益肾，兼顾祛邪；肝硬化腹水期治以扶正解毒利水，慎用攻破。通过辨证论治，使正气强盛，邪毒祛除，则疾病向愈。     

双氯芬酸钠缓释制剂的释放度考察

目的:考察双氯芬酸钠缓释制剂的体外释放度.方法:采用转篮法和pH6.8的人工肠液对市售4个厂家的双氯芬酸钠缓释片和缓释胶囊的释放度进行了测定,并对释放度数据进行方程拟合及t检验.结果:A、C厂家产品的释放规律较符合Weibull方程,而B、D厂家产品的释放规律较符合Higuchi方程.各厂家产品的释放度在1 h,6 h时差异有显著性,在12 h时差异无显著性.结论:不同厂家双氯芬酸钠缓释制剂的释放度差异存在显著性.     

肺炎克雷伯菌质粒β-内酰胺酶的筛选及其耐药性

目的了解头孢类耐药肺炎克雷伯菌(KPN)质粒β-内酰胺酶的分布及耐药性,寻求最佳的检测方法. 方法双纸片协同试验和三维试验检测超广谱β-内酰胺酶(ESBLs),表型筛选法和三维试验检测质粒AmpC酶. 结果 182株KPN中,ESBLs检出率双纸片协同试验为42.85%、三维试验为45.05%,两法总符合率为95.12%;表型筛选法显示9株(4.9%)产AmpC酶,三维试验则为7株(3.8%);4株(2.2%)同时产两种酶;产酶株对三代头孢高度耐药,对喹诺酮类、复方新诺明交叉耐药率也很高,对氨基糖苷类有一定敏感性,尚未发现亚胺培南耐药株. 结论 KPN质粒β-内酰胺酶以ESBLs为主;双纸片协同试验操作简便,为检测ESBLs最常用方法;AmpC酶表型筛选法只能作为初筛,确证还需用三维试验证实.     

Continuous and online analysis of heart rate variability

Spectral analysis of heart rate variability provides a probe to assess the function of the sympathetic and parasympathetic nervous systems. Time-frequency analysis of heart rate variability is useful for investigating autonomic nervous function in patients with syncope or non-sustained ventricular tachycardia, or in anaesthesia, etc. In this paper, we developed an algorithm for continuous and online analysis of heart rate variability. The algorithm was simulated and evaluated in MATLAB, and implemented on the digital signal processor. The electrocardiogram signals from MIT/BIH arrhythmia database and one patient with syncope demonstrate the capability of the proposed method in the continuous and online analysis of heart rate variability.     

In vivo albendazole treatment of Taenia crassiceps cysticerci strain WFU: proliferation, damage, and recovery

Taenia crassiceps has been widely experimented as a model for in vitro and in vivo studies on drug responses. The purpose of this study was to treat BALB/c mice infected with T. crassiceps strain WFU with commercially available albendazole and to analyze the reduction in parasite infrapopulations. Here, we describe the reduction and apparent damage of T. crassicceps WFU cysticerci in infected mice after antihelminthic drug treatment and subsequent inoculation of those treated parasites into a naïve host. We were able to reduce significantly the parasite counts to 33 and 48 % after albendazole treatment for 20 or 25 days and compared with the untreated mice. We also observed morphological damage such as the partial blebbing in the tegument and parenchyma of treated parasites, as well as disorganized musculature and the loss of cell membranes in subtegumental tissue section. However, larvae from albendazole-treated mice inoculated into the next host were able to become re-established in the next murine host due, probably, to the survival of proliferative parasite cells.
