OBJECTIVE： To evaluate the medium- to long-term efficacy of ligustrazine plus conventional medicine treating ischemic stroke. METHODS： Randomized controlled trials （RCTs） testing ligustrazine in the treatment of acute isch- emic stroke were retrieved from Cochrane Library, PubMed, Excerpta Medica Database, Chinese Medi- cal Journal Database, Chinese Biomedical Data- base, China National Knowledge Infrastructure Da- tabase, and Chinese Clinical Trial Register, and then identified by the inclusive and exclusive criteria. The quality of trials was assessed with the Co- chrane Handbook 5.1, a risk of bias assessment toot. RevMan 5.1 was used for ***： Three RCTs involving 643 patients were included. Compared to conventional medicine treatment alone, ligustrazine plus conventional medicine treatment showed significant difference in reduction of stroke recurrence either at the end of 1-year follow-up [RR=0.42, 95% CI （0.18, 0.94）, P〈 0.05] or 3-years observation [RR=0.48, 95% C/（0.27, 0.83）, P〈0.05]. The ligustrazine group also showed higher survival rate [RR=1.67, 95% CI （1.02, 0.2.71）, P〈0.05] and significantly better effective rate [RR= 1.28, 95% CI（1.10, 1.50）, P〈0.05] than that of the control group at the end of 1 year visit. Only one tri- al conducted safety assessment and no adverse events were reported. The methodological quality of all the trials included was generally poor. CONCLUSION： The findings provided evidence that the combination of ligustrazine and conven- tional medication was medium- and long-term ben- eficial to the patients suffering ischemic stroke. But more RCTs of high quality are needed to further prove the efficacy and safety of using ligustrazine for ischemic stroke.

目的探讨噪声作业人员代谢综合征(metabolic syndrome,MS)与噪声性听力损失(noise-included hearing loss,NIHL)的相关性。方法采用方便抽样法,选取某汽车制造企业850名男性噪声作业人员为研究对象,采用问卷调查和职业健康检查相结合的方法,收集研究对象一般人口学资料、体检资料等各类信息,按照高频听力损失情况,将噪声作业人员分为听力损失组(326人)和听力正常组(524人),采用单因素分析比较两组人员上述资料差异情况,采用二分类多因素logistic回归模型分析噪声作业人员发生NIHL的影响因素。结果该企业噪声岗位超标率为39.47%(15/38),主要集中在焊装工和涂装工岗位。听力损失检出率为38.35%(326/850),MS检出率为27.53%(234/850)。听力损失组肥胖、高水平三酰甘油、高水平空腹血糖、高血压、MS的检出率、接触的噪声声级均高于听力正常组(P 15年组发生NIHL的风险分别升高至1.553、1.727倍(P <0.001);相比无MS组,MS组发生NIHL的风险升高至1.863倍(P <0.001)。噪声声级每增加1dB(A),发生NIHL的风险升高至1.567倍(P <0.001)。结论 MS与NIHL存在相关性。除了要重视控制工作环境中的噪声声级,还要注意采取低糖、低盐、低钠饮食,降低饱和脂肪酸的摄入量,加强体育锻炼等方式,有效控制作业人员的血压、血糖、血脂水平,从而减少NIHL发病风险。

目的调查少数民族医药循证能力现状及发展需求,探讨提升少数民族医药循证能力的有效策略。方法在少数民族医药医疗单位及研究机构进行问卷调查。问卷内容包括3个维度:对循证医学的认知和态度、少数民族医药发展的优势及推进循证医学面临的困难、少数民族医药循证能力提升的需求及建议。结果共回收有效问卷501份,其中针对参与数量不足的少数民族医药地区补发问卷回收103份。问卷中少数民族医药从业者354份(70.66%),包括藏医、蒙医、维吾尔医、壮医、朝鲜医等少数民族医药。146例(29.14%)表示了解循证医学,70.86%(355例)的被调查者对循证医学“一般了解”或“不太了解,没听说过”,93.61%(469例)的被调查者认为引入循证医学能推动少数民族医药的发展。少数民族医药领域内推进循证医学面临的最大困难是缺乏循证医学专业人才,不知道如何运用循证医学推动临床实践(442例,88.22%)。关于循证能力提升的9分制重要性评分中,临床实践指南的规范制订得分(7.50±1.90)和常见临床研究的样本量估算方法得分(7.45±1.90)较高。临床科研素养提升的需求方面,选择最多的是专家学术讲座与经验分享(404例,80.64%)和相关循证方法学专著(401例,80.04%)。结论少数民族医药从业者对引入循证医学持积极态度,循证医学的教育与普及尚有较大发展空间。循证能力的提升主要可从培养或引进循证医学人才、建设临床研究循证支持平台、定期开展学术讲座及交流、加强少数民族医药理论和评价体系建设等措施具体落实,走符合少数民族医药特色的循证之路。

随着建筑低碳发展,热泵和光伏等可再生能源技术在建筑能源系统中逐步得到规模化应用,然而其无序应用会给电网配电和承载带来较大压力。本文提出了1种“热泵+蓄能+光伏”冷热电耦合建筑能源系统,采用源网荷储联动运行方法,通过有序调节光伏、配电网、热泵、蓄能运行状态,实现建筑低成本供冷供热,促进可再生能源发电本地消纳和电网调度平衡。同时,本文通过模拟平台验证了源网荷储联动运行方法的应用效果,结果表明,采用源荷储联动运行方法较热泵直供运行方法,在冬季部分负荷典型日,可再生能源本地消纳提升24.13%,系统全天运行费用降低34.10%,电力移峰量提高27.60%;在夏季部分负荷典型日,可再生能源本地消纳提升21.47%,系统全天运行费用降低33.20%,电力移峰量提高21.11%。全年能源系统可再生能源本地消纳提升22.47%,运行费用降低33.59%,电力移峰量提高15.95%,系统静态投资回收周期为4.67 a。本文表明了“热泵+蓄能+光伏”系统采用源网荷储联动运行方法在很大程度上节省了系统运行费用,促进了本地可再生能源消纳,平衡了电网,研究结果可用于指导工程应用。

党的十八大以来,习近平多次就“讲好中国故事,传播好中国声音,增强在国际上的话语权”作出重要指示。党的十九大进一步强调,要“推进国际传播能力建设,讲好中国故事,展现真实、立体、全面的中国”。近年来,我国国际传播事业取得了巨大进展,中国故事的国际吸引力、影响力不断增强。但仍要看到,我们讲述中国故事的实际效果与预期仍存在着一定差距,其中既有其客观因素,也有主观方面的问题。
