糖康明胶囊对糖尿病大鼠血糖、血脂及血液流变性影响

目的：探讨糖康明胶囊对糖尿病大鼠血糖、血脂及血液流变性的影响。方法：分别以糖康明胶囊低、高剂量给大鼠灌胃给药,连续15d。结果：糖康明胶囊对正常大鼠血糖及血清胰岛素含量均无影响,但对四氧嘧啶所致的高血糖大鼠的血糖有明显降低作用,同时能升高血清胰岛素含量,降低总胆固醇、三酰甘油及血液粘度。结论：糖康明胶囊降糖作用与刺激胰岛β细胞释放胰岛素等有关。     

Assessing the background levels of body fluids on hands

Forensic scientists are often asked to assist the court by evaluating the significance of finding body fluids on the hands of an individual; however, there is an absence of published data regarding the background levels of body fluids on hands. Whilst the scientist can use casework experience to inform the courts on the significance of the results, it would be advantageous to have data which could assist with this interpretation. This study was designed to ascertain the background levels of blood, semen, saliva, hairs/fibres and staining/debris on hands in the general population by sampling from delegates attending a scientific conference.The findings suggest that approximately one third of the population would be expected to have hairs or fibres on their hands and that females are more likely to have visible staining on their hands than males. Presumptive tests for blood and semen yielded negative results in all samples; however, almost 2 % of the samples were found to contain a very low number of sperm heads. In contrast, the majority of samples tested positive for the presence of saliva using the presumptive Phadebas® amylase test. The data supports the caution applied by forensic practitioners when evaluating the presence of saliva detected using the presumptive Phadebas® amylase test based on the lack of specificity and indicates that the RSID™-Saliva test would be more suitable to use.     

灯盏花素注射液治疗冠心病不稳定型心绞痛疗效观察

目的观察灯盏花素注射液治疗冠心病不稳定型心绞痛的疗效及对凝血指标、高敏C反应蛋白(highsensitive C-reactive protein,hs-CRP)、血脂、血糖的影响。方法选择40例冠心病不稳定型心绞痛患者,随机分为治疗组和对照组各20例,治疗组给予灯盏花素注射液加西药常规治疗,对照组仅予西药常规治疗,观察治疗前后心绞痛、心电图、中医证候疗效及凝血酶原时间(prothrombin ti me,PT)、活化部分凝血活酶时间(activated partial thromboplastin ti me,APTT)、血浆纤维蛋白原(plasma fibrinogen,FG)、hs-CRP及血脂、血糖等指标变化。结果治疗组在缓解心绞痛症状和改善心电图疗效方面与对照组比较,差异无统计学意义(P>0.05),在改善中医证候疗效方面显著优于对照组(P<0.05)。治疗组在升高PT、APTT,降低FG和hs-CRP方面显著优于对照组(P<0.05,或P<0.01),治疗组总胆固醇(total cholesterol,TC)、低密度脂蛋白胆固醇(low density lipoprotein-cholestero...
