目的 系统评价心脉通治疗冠心病的临床疗效及其安全性。方法 2名研究者独立系统地检索心脉通治疗冠心病的文献,其中包括维普中文科技期刊全文数据库(VIP)、PubMed 电子期刊全文数据库、中国学术期刊全文数据库(CNKI)、The Cochrane Library 数据库、万方数据库等6个数据库。同时运用Review Manager 5.4 软件进行本研究的数据处理。结果 最终共纳入8篇文献,共计985名心脉通治疗冠心病患者。治疗前后的临床疗效、发作频率、血脂水平的Meta分析结果显示心脉通组优于常规治疗组。有3项纳入试验报告不良反应。结论 心脉通治疗冠心病的临床疗效优于常规治疗。心脉通不仅可以降低冠心病发作频率,缩短其发作持续时间,还能调节血脂水平,在治疗冠心病方面疗效确切,值得临床参考应用。

Objective To systematically evaluate the clinical efficacy and safety of Xinmaitong in the treatment of coronary heart disease (CHD). Methods Two researchers searched the literatures of Xinmaitong in the treatment of coronary heart disease independently and systematically, including VIP Chinese Sci-tech Journal full-text Database (VIP), PubMed Electronic Journal full-text Database, Chinese Academic Journal full-text Database (CNKI), The Cochrane Library Database and Wanfang Database. At the same time, Review Manager 5.4 software was used to process the data of this study. Results A total of 8 articles were included, and a total of 985 patients with coronary heart disease were treated with Xinmaitong. The results of Meta analysis of clinical efficacy, attack frequency and blood lipids level before and after treatment showed that Xinmaitong group was better than routine treatment group. Three items were included in the report of adverse reactions. Conclusions The clinical effect of Xinmaitong in the treatment of coronary heart disease was better than that of routine treatment. Xinmaitong can not only reduce the frequency and duration of coronary heart disease attack, but also regulate blood lipids level. Xinmaitong was effective in the treatment of coronary heart disease and is worthy of clinical reference.

目的 通过超声造影成像技术( CEUS)观察颈动脉斑块内新生血管的情况,探讨颈动脉斑块的厚度与新生血管的关系。方法 选择颈动脉粥样硬化患者40例,经常规超声确诊存在斑块,共64个,应用CEUS成像技术检测斑块内新生血管情况。结果 不同厚度的颈动脉斑块的增强强度与斑块厚度成正相关(r=0.897 6,P=0.000 0)。结论 超声造影成像技术可以在常规超声的基础上通过检测斑块内的新生血管,进而判断斑块的性质,提供更多有用的信息进一步评估颈动脉斑块内新生血管增强强度与斑块厚度存在线性正相关性。

Objective To evaluate the neovascularization in carotid plaques by gray-scale harmonic contrast echocardiography (CEUS), and to investigate the relationship between the thickness of carotid artery plaque and the neovascularization.Methods 40 patients with carotid atherosclerosis were selected, and 64 plaques were diagnosed by regular ultrasound. The neovascularization in plaques was detected by CEUS imaging technique.Results The enhanced strength of carotid plaques with different thickness was positively correlated with plaque thickness (r=0.8976,P=0.0000).Conclusion Ultrasound contrast imaging can detect angiogenesis within the plaque based on conventional ultrasound, and then determine the nature of the plaque. More useful information is provided to further evaluate the linear positive correlation between the intensity of neovascularization and the thickness of plaque in carotid plaque.

目的 探讨本中心引起儿童泌尿系统感染的常见病原菌的分布以及耐药情况,为临床合理选用抗菌药物提供参考。方法 回顾性分析本医疗中心2012年1月—2013年12月2463例泌尿系统感染患儿中段尿标本培养及药敏检测结果。结果 2463例患儿中段尿标本共培养病原菌479株,阳性率为19.45%。其中革兰阴性杆菌309株(64.51%),革兰阳性球菌138株(28.81%),真菌32株(6.68%,主要为白假丝酵母菌)。分离率前7位的病原菌依次为大肠埃希菌(36.53%)、肺炎克雷伯菌(12.73%)、粪肠球菌(D群)(12.32%)、屎肠球菌(D群)(10.23%)、真菌(6.68%)、铜绿假单胞菌(5.22%)、奇异变形菌(3.13%),革兰氏阴性杆菌以大肠埃希菌和肺炎克雷伯菌为主,其中产超广谱β‐内酰胺酶菌株125株,比例高达71.42%;革兰阳性球菌以肠球菌(D群)为主,金黄色葡萄球菌检出率为2.30%,其中耐甲氧西林株占27.27%。结论 大肠埃希菌仍为儿童泌尿系统感染的主要病原菌,且存在多重耐药菌感染情况,革兰氏阳性球菌有增多的趋势;明确病原菌种类及药敏结果,对临床合理应用抗菌药物治疗儿童泌尿系统感染有重要意义。

Objective To research the distribution of common pathogenic bacteria and drug resistance of urinary tract infection in the hospital for providing reference of antimicrobial drugs for clinical reference. Methods Pathogenic bacteria isolated from the germiculture positive specimens of midstream urine and the antimicrobial susceptibility test results from Jan 2012 to Dec 2013 in our hospital were retrospective summarized. Results 479 strains pathogenic bacteria were isolated from 2463 urine samples totally. The positive rate was 17.3％, with 309 strains of gram-negative bacilli (64.51％),138 strains of gram-positive coccus(28.81％),32 strains of fungi(6.68％).The top 7 isolation of pathogens were strains of escherichia coli(36.53％),strains of klebsiella pneumoniae(12.73％),strains of enterococcus faecalis D group(12.32％),strains of enterococcus faecium D group(10.23％),strains of fungi(6.68％),strains of pseudomonas aeruginosa(5.22％),strains of staphylococcus epidermidis(3.13％).125 strains of klebsiella pneumoniae produced ESBL were detected out with the rates of up to 71.42%. The strains of gram-negative bacteria were based on enterococcus faecalis (D group),yet staphylococcus aureus methicillin resistant strains accounted for 27.27%. Conclusion Escherichia coli is the main pathogenic bacteria of child urinary tract infection and the multidrug resistance of the pathogenic bacteria is in a very serious situation. And gram-positive cocci is going to be increasing. It is necessary to make clear pathogens and drug sensitivity results, which is important to guide clinic make use of antibacterial agents exactly to cure infection of urinary system in children.
