针刺治疗慢性无菌性前列腺炎文献系统评价

目的：系统评价针刺治疗慢性无菌性前列腺炎（CNBP）的有效性。方法：按照循证医学的要求,以针刺、体针、电针、头针、CNBP等为主题词,检索国内相关医学数据库,以随机临床对照试验为纳入标准。治疗组为针刺或针刺加其他疗法,对照组为药物,把CNBP痊愈率为测量指标。共纳入33篇文献,并对其中6篇文献采用RevMan4．2．9进行Meta分析。结果：6篇文献的痊愈率合并OR=3．48,95％CI[2．46,4．92],治疗组对CNBP的疗效优于对照组（P〈0．05）。结论：从纳入的国内文献来看,针刺治疗CNBP有效,且效果优于药物,但是仍需要更多的高质量文章来证实。     

缺陷腺病毒载体表达重复10次的Aβ3-10基因疫苗鼻黏膜免疫APPswe, PSEN1dE9转基因小鼠可诱导出Th2型免疫反应

Immunotherapy for Alzheimer’s disease (AD) is effective in improving cognitive function in transgenic mouse models of AD. Because the AN1792 [beta-amyloid (Aβ) 1-42] vaccine was halted because of T cell mediated meningoencephalitis, many scientists are searching for a novel vaccine to avoid the T cell mediated immune response caused by the Aβ1-42. Importantly, the time when the immunization is begun can influence the immune effect. In this study, an adenovirus vaccine was constructed containing 10 × Aβ3-10 repeats and gene adjuvant CpG DNA. Transgenic AD mice were immunized intranasally for 3 months. After 10 × Aβ3-10 vaccine immunization, high titers of anti-Aβ42 IgG1 predominant antibodies were induced. In spatial learning ability and probe tests, the 10 × Aβ3-10 immunized mice showed significantly improved memories compared to control mice. The 10 × Aβ3-10 vaccine resulted in a robust Th2 dominant humoral immune response and reduced learning deficits in AD mice. In addition, the 10 × Aβ3-10 vaccine might be more efficient if administered before Aβ aggregation at an early stage in the AD mouse brain. Thus, the adenovirus vector encoding 10 × Aβ3-10 is a promising vaccine for AD.     

蒙药三味皂矾汤的抗炎作用研究

目的：观察三味皂矾汤的抗炎作用,为该药的开发研究提供实验基础。方法：选择大鼠棉球肉芽肿、鸡蛋清致大鼠足肿胀和甲醛致大鼠足肿胀等实验模型观察三味皂矾汤的抗炎效果。结果：三味皂矾汤对大鼠棉球肉芽组织的增生有显著的抑制作用,其抑制率最高达到31.82%（P<0.01）,对1~6 h内蛋清致大鼠足肿胀的抑制率最高达到31.61%（P<0.01）,对1~24 h内甲醛致大鼠足肿胀的抑制率最高达到20.09%（P<0.01）。结论：三味皂矾汤对亚急性吞噬细胞的浸润性炎症和对慢性增殖性组织变异性炎症均有良好的抑制作用。     

氟伐他汀对脂多糖和血管紧张素Ⅱ致大鼠主动脉内皮细胞TF和TFPI表达的影响

目的 研究氟伐他汀(fluvastatin)对脂多糖(LPS)和血管紧张素Ⅱ(AngⅡ)诱导的离体大鼠主动脉内皮细胞(RAEC)表达组织因子(TF)和组织因子途径抑制物(TFPI)的影响.方法 体外培养RAEC,分别给予LPS和AngⅡⅡ刺激,采用ELISA法检测氟伐他汀对RAEC TF和TFPI表达的影响.结果 氟伐他汀0.01、O.1、1和10μmol/L组能剂量依赖性抑制LPS和AngⅡ引起的TF表达增强;氟伐他汀0.01、0.1、1和10μmnol/L.组TFPI表达增强,呈剂量依赖性.结论 氟伐他汀能抑制引起血栓形成的TF表达,增加TFPI表达.

Congenital hypoplastic anemia inhibition of erythropoiesis by sera from patients with congenital hypoplastic anemia

An in vitro marrow culture assay designed to measure erythropoietic capability was used to ascertain the presence of an inhibitor in the sera of patients with congenital hypoplastic anemia (CHA). Marrow cells from nine anemic CHA patients responded to the stimulatory effect of exogenous erythropoietin (EPO) by an increase in heme synthesis in the presence of normal serum. The effect on heme synthesis was less than that observed with normal marrow cells. CHA serum inhibited heme synthesis by both normal and CHA marrow cells. It is concluded that an in-inhibitor of erythropoiesis is present in serum from CHA patients. This inhibitor most likely blocks the EPO-sensitive stem cell receptor sites, causing decreased response to the hormone.

Sexual precocity: sex incidence and aetiology

The aetiology of 197 girls and 16 boys presenting with sexual precocity was reviewed. Ninety one girls and four boys had central precocious puberty (M:F 23:1); a cause was identified in all the boys but in only six girls. All boys with precocious puberty need detailed investigation; in girls investigation should be based on clinical findings, particularly the consonance of puberty.
