目的:对近年来黄芪治疗缺血性脑损伤作以总结,以阐明其在治疗缺血性脑血管病中的有效作用。资料来源:检索数据库Medline1966-01/2005-05有关黄芪的药理作用及其治疗缺血性脑损伤的文章,检索词为“astragulus,cerebralischemiainjury”,限定文章语言种类为英文。同时检索中文医学期刊全文数据库1994-01/2004-12及万方数据库1998-01/2005-11有关黄芪的药理作用及其治疗缺血性脑损伤的文章,检索词为“黄芪,缺血性脑损伤”,限定文章语言种类为中文。资料选择:对资料进行初审,选取包括黄芪与缺血性脑损伤的动物实验和临床研究文章。质量评价主要考察资料的真实性,实施过程是否严密。关于重复实验的多篇文章,选取样本量较大的文章予以纳入。资料提炼:共检索到72篇中文和94篇英文,选取较新的或经典的探讨黄芪的药理作用及其治疗缺血性脑损伤的文章共25篇。排除重复性研究。资料综合:①黄芪具有清除自由基,降低血浆内皮素含量,防止脂质过氧化,改善脑功能的作用。②黄芪能降低兴奋性氨基酸的含量,抑制热休克蛋白70的表达,减轻缺血性脑损伤。③黄芪能提高脑缺血后Bcl-2的水平,拮抗P53和Caspase-3的表达,有效抑制脑缺血引起的神经元凋亡。④黄芪能降低血管通透性,改善脑缺血后血液流变状态,减轻脑缺血损伤。⑤黄芪能抑制脑缺血早期胶质细胞原纤维酸性蛋白过度表达,减轻海马区锥体细胞损伤,保护缺血后脑损伤。结论:黄芪能显著改善脑缺血患者的临床症状,降低致残率,且安全无副作用,有广阔的临床前景。

'astragulus, cerebral ischemia injury', we searched the Medline database for the relevant articles on pharmacological effect on astragulus and the treatment of cerebral ischemic injury published from January 1966 to May 2005 in English. Meanwhile, using the same keywords we searched the China Journal Full-text Database from January 1994 to December 2004 for the relevant articles on pharmacological effects of astragulus and the treatment of cerebral ischemic injury and published between January 1998 and November 2005 in Wanfang Database in Chinese.STUDY SELECTION: All articles were selected firstly, the articles relevant to experiment animal research and clinical research of astragulus and cerebral ischemic injury were selected. the evaluation of quality mainly inspected the validity of data, and the procedure of putting in practice whether accuracy or not. Among those articles with repetitive experiment, the articles with large number of samples were selected.DATA EXTRACTION: A total of 72 articles in Chinese and 94 articles in English were found. the latest or classical articles about pharmacological effects of astragulus and in the treatment of cerebral ischemic injury were collected, totally 25 articles. the repetitive articles were excluded. DATA SYNtheSIS: ①Astragulus had the role of eliminating free radical, decreasing serum endothelin, avoiding lipid peroxidation and improving cerebral function. ②Astragulus could reduce the content of excitatory amino acid, restrain the expression of heat shock protein 70 and alleviate the cerebral ischemic injury. ③Astragulus could enhance the level of Bcl-2 after cerebral ischemia, antagonise the expression of P53 and Caspase-3, effectively inhibit neuronal apoptosis caused by cerebral ischemia. ④Astragulus could reduce the permeability of blood vessel, improve the condition of hemorrheology after ischemia, and alleviate the cerebral ischemic injury. ⑤Astragulus could restrain the hypernomic expression of glial fibrillary acidic protein in the period of early cerebral ischemia, alleviate the trauma of stratum pyramidale hippocampi, and protect cerebral cerebral lesion after ischemia.CONCLUSION: Astragulus can significantly improve the clinical symptom of the patients with cerebral ischemia and reduce the diseability. Furthermore, astragulus is safe, has no side effect and has wide clinical future.

球体是工业设计中常用的造型语言,但由于某些需要或限制,往往采用多面体来近似表示球体。文章提出了用多面体逼近球体效果的评判标准和改进方法,以及多面体对球体的逼近在工业设计中的应用,最后以实例加以说明。

目的探讨大黄对非尿毒症慢性肾衰竭(chronic renal failure,CRF)患者微炎症状态的影响。方法选择2010年1月至2011年3月在南昌大学第二附属医院及江西省肿瘤医院门诊及住院的非尿毒症CRF患者60例,按不同的治疗方法分为治疗组和对照组,每组30例。对照组患者常规给予降压药、红细胞生成素及对症治疗;治疗组在对照组治疗的基础上加用生大黄10g开水泡服,1次.d-1。2组疗程均为2周。选择同期在南昌大学第二附属医院门诊体检科体检的健康者(正常对照组)30例。治疗组和对照组在治疗前后分别检测血清肌酐(Scr)、淀粉样蛋白A(SAA)、超敏C反应蛋白(hs-CRP)的水平,同时计算内生肌酐清除率(Ccr)。并与正常对照组进行对比。结果 2组患者治疗后血清Scr和Ccr水平与治疗前比较差异均无统计学意义(均P>0.05),2组患者治疗前血清SAA、hs-CRP水平均较正常对照组显著升高(均P<0.05),对照组患者治疗前血清SAA、hs-CRP水平与治疗后比较差异均无统计学意义(均P>0.05),而治疗组患者治疗后血清SAA、hs-CRP水平均较治疗前、对照组显著下降(均P<0.05)。相关性分析结果显示,60例非尿毒症CRF患者治疗前血清SAA水平与血清hs-CRP水平呈正相关(r=0.866,P<0.05)。结论非尿毒症CRF患者存在微炎症状态。大黄能改善非尿毒症CRF患者微炎症状态,但对其肾功能无明显地改善。

Objective To explore the effects of rhubarb on microinflammation state in non-uremic patients with chronic renal failure.Methods Sixty non-uremic outpatients and inpatients with chronic renal failure treated from Out-patients and Hospitallization of the Second Affiliated Hospital of Nanchang University and Jiangxi Province Tumor Hospital from January 2010 to March 2011 were randomly divided into treatment group and control group,with 30 patients in each group.All patients were routinely offered antihypertensive drugs,erythropoietin and heteropathy.In addition,patients in treatment group were additionally given rhubarb decoction(10 g once daily).Treatments were maintained for 2 weeks.Thirty healthy subjects from the Out-patients Department of Physical Examination of the Second Affiliated Hospital of Nanchang University were selected as normal controls.the levels of serum creatinine(Scr),amyloid A(SAA) and high sensitivity C-reative protein(hs-CRP) were detected before and after treatment,and creatinine clearance rate(Ccr) was calculated.Results No significant changes in levels of Scr and Ccr were found in patients after therapy(all P〉0.05).Compared with normal controls,levels of SAA and hs-CRP obviously increased in patients before treatment(all P〈0.05).Compared with values before treatment,levels of SAA and hs-CRP did not changed in control group(all P〉0.05),but obviously decreased in treatment group after therapy(P〈0.05).Furthermore,levels of SAA and hs-CRP in treatment group were significantly lower than those in control group after therapy(all P〈0.05).there was a positive relationship between SAA levels and hs-CRP levels before treatment in non-uremic patients with chronic renal failure(r=0.866,P〈0.05).Conclusion Microinflammation state exists in non-uremic patients with chronic renal failure and can be improved by rhubarb,which has no obvious influence on renal function.
