Effect of Zhuchun Pill on immunity and endocrine function of senile Kidney-Yang Deficiency) on immunity and endocrine function of senile Kidney-Yang Deficiency

Objective: To evaluate the effect of Zhuchun pill (ZCP) on senile Kidney-Yang Deficiency (KYD).Methods: By single blind method, 45 elderly males with KYD were divided randomly into the ZCP group (treated by ZCP) and the control group (treated by placebo, starch capsule) and treated for 3 months.Results: ZCP could greatly improve the main symptoms of KYD,P < 0. 01 in comparison with the control group. After treatment, in the ZCP group, the³H-TdR lymphocyte transformation rate, levels of serum C₃, IgA, IgD, IgG and IgM, superoxide dismutase, plasma adrenocortical hormone, testosterone and cyclic adenosine monophosphate all increased,P < 0.01, and plasma lipid peroxide decreased,P < 0.01. While in the control group, no remarkable change was found in these parameters.Conclusion: ZCP could improve the KYD through regulating the immunity, endocrine function and scavenging the free radicals in organism.     

不同频率电针“内关”穴对急性心肌缺血模型家兔心交感神经电活动的影响

目的通过观察心交感神经电活动变化情况,比较不同频率电针对穴位效应的影响,为临床治疗选择低频电针频率提供实验依据。方法健康青紫蓝家兔60只,雌雄各半,体质量(2.5±0.3)kg,随机选10只做正常对照组,其余家兔在麻醉状态下采用左冠状动脉旋前降支结扎法复制急性心肌缺血模型,随机分为模型对照组、低频(2 Hz)电针组、高频(100Hz)电针组和混频(2/100 Hz)电针组,每组10只。采用BIOPAC生物信号采集系统记录心交感神经电信号,同时接入SKY-A8生物信号处理系统进行数据处理。结果急性心肌缺血模型家兔心交感神经电活动兴奋性降低,与正常组家兔比较有显著性差异(P<0.01)。在电针后即刻及停针15min时,心交感神经电活动显著增强,低频电针组、高频电针组及混频电针组家兔的心交感神经电活动的频率与模型组有显著性差异,且以低频电针组效果优于高频电针组和混频电针组,而高频电针组和混频电针组之间无显著性差异(P>0.05)。结论不同频率电针"内关"穴均可明显改善急性心肌缺血家兔的心交感神经电活动,且存在相对特异性,以低频电针组提高心交感神经兴奋性作用最强。     

加味青蒿鳖甲汤对髓系MRD-L患者CD_(34)~+细胞源DC诱导过程中IL-12的影响

目的:探讨加味青蒿鳖甲汤对树突细胞(DC)诱导和对IL-12分泌的影响。方法:本研究采用体外培养的方法,用含不同剂量(高、中、低)加味青蒿鳖甲汤动物血清联合细胞因子、不含药血清联合细胞因子及单纯用细胞因子,共同培养缓解期急性髓系白血病(AML-CR)患者骨髓中分离提取的CD+34细胞,诱导其成为DC,观察各组在不同阶段对DC成熟的影响,以及各组血清中IL-12的分泌变化。结果:含药血清均能上调DC表面特征性分子及共刺激分子CD80、CD83、CD86表达水平,较单纯细胞因子组比较有显著性差异(P<0.01),且含中剂量药血清更能促进DC分泌IL-12(P<0.01)。结论:联合细胞因子的含加味青蒿鳖甲汤的血清,可使来源AML-CR骨髓的CD+34,在体外比单纯用细胞因子诱导培养DC能够更好地促进DC的生长、成熟和分化,并能促进DC分泌IL-12,增加抗肿瘤作用。     

稳定期慢性阻塞性肺疾病患者认知功能相关因素研究

目的：探讨影响稳定期慢性阻塞性肺疾病（ COPD）患者的认知功能的相关因素。方法：选取2013年3月至2014年9月于我院就诊的稳定期COPD患者135例,采用蒙特利尔认知评估量表（ MoCA）评价稳定期COPD 患者与健康对照人群的认知功能差异,并观察 COPD 患者不同肺功能、PaO2水平及PaCO2水平对患者认知功能的影响。结果：135例稳定期COPD患者中97例（71．85％）患者存在认知功能障碍。 COPD 组MoCA量表总分为（21．55±3．63）分,对照组MoCA总分为（26．71±2．33）分,差异有统计学意义（P＜0．01）。根据患者肺功能情况、PaO2水平及PaCO2水平分别分组,肺功能良好组、PaO2≥60mmHg组、PaCO2＜50mmHg组较肺功能差组、PaO2＜60mmHg 组、PaCO2≥50mmHg组MoCA评分在视空间与执行、命名、延迟记忆、注意、语言、抽象、定向各分项及总分均显著降低,差
　　异均有统计学意义（P＜0．05）。线性回归分析显示年龄、文化程度、肺功能、PaO2水平及PaCO2水平是影响慢阻肺患者认知功能的主要因素。结论：稳定期COPD 患者广泛存在认知功能障碍,肺功能越差、PaO2水平越低、PCO2水平越高,MoCA评分越低;年龄、文化程度、肺功能、PaO2水平及PaCO2水平是影响慢阻肺患者认知功能的主要因素。     

Clinical study on the Piweiping capsule in treating patients with metaplasia of gastric mucosa

Objective: To evaluate the therapeutic effect of Piweiping capsule (PWPC) in treating patients with metaplasia of gastric mucosa and explore its mechanism.Method: One hundred and forty-three patients were diagnosed as chronic superficial atrophic gastritis of gastric antrum or with metaplasia by means of gastroscopic observation with pathological biopsy examination. They were divided into 4 types (type I - IV) according to Syndrome Differentiation of traditional Chinese medicine, and each type was subdivided according to treatment into 2 groups, 75 in the PWPC group and 68 in the Sanjiu Weitai ( ) group. Patients of PWPC group were in accordance with the type to which they belong treated with PWPC I, II, HI, IV respectively, while patients of SJWT group were all treated with SJWT. After 3 - 6 months of treatment, the clinical effect, pathological examination of gastric mucosa and some other parameters were observed.Results: The improvements of gastric mucosa cyclic adenosing monophosphate (cAMP), deoxyribonucleic acid (DNA),³H-thymopyrimidine nucleoside and lymphocyte transformation of the treatment group were all superior to those of SJWT group,P < 0.05-0.001. In the PWPC group, the curative rate and total effective rate on symptom were 49.3 % and 92.0% respectively, and the curative rate and total effective rate on intestinal metaplasia were 45.3 % and 62.7%. As for the SJWT group, they were 29.4%, 67.6%, 10.3% and 29.4% respectively. The difference between the two groups was significant,P < 0.001. Conclusion: PWPC could reverse the intestinal metaplasia through improving the gastric cAMP, DNA and strengthening the cellular immunity and the effect would be enhanced when the treatment was based on Syndrome Differentiation.
