甘肃积石山 M_(s)6.2级地震的震害特征与启示

2023年12月18日,甘肃省临夏回族自治州积石山保安族东乡族撒拉族自治县(35.70°N,102.79°E)发生了6.2级地震,震中烈度为VIII度。地震发生后,通过实地烈度评估与科学考察,对震区VI~VIII度区不同建(构)筑物与生命线工程的震害特点进行了统计分析;从抗震设计与施工管理、场地放大效应与地震次生灾害对建筑结构抗震性能的影响等角度,提出了此次地震的震害启示。结果表明:1)严重破坏和毁坏的建筑结构主要集中在老旧的土木结构、砖木结构和无设防或设防不规范的砖混结构。2)造成建筑结构破坏的主要原因是少量自建房抗震设计和施工的不规范、场地放大效应和地震次生灾害。3)优化和改良生土砌筑材料,改进纵横墙间的拉结措施,强化结构整体性是提高土木结构抗震的有效方法;普及“上下圈梁与构造柱”等基本抗震设防措施,规范水泥砂浆强度,提升农村工匠的施工水平,可有效提高砌体结构的整体性,避免房屋出现整体性垮塌;室内洗手间的墙体应该与房顶、纵横墙间建立有效联接,提高结构的抗震性能。4)孤突斜坡、河流高阶地与岸边为抗震不利地带。当建造用地极为匮乏,不得不选址在这些场地之上时,应该综合考虑场地的地形地貌特征、岩土体物理力学特性、水文地质条件、抗震设防目标、建筑结构类型等影响因素,做好地震灾害风险评估,根据评估结果进行科学设防。灾后重建过程中,应由政府统一规划选址、统一设计,规范施工。

黄土液化作用及其次生灾害风险评估方法初探——以积石山M_(S)6.2地震为例

2023年12月18日甘肃积石山6.2级地震引发的黄土液化泥石流地质灾害,造成了大量人员伤亡和财产损失。以此为背景,系统梳理了液化调查、风险评估和风险区划的工作思路:选定地区液化的内在和诱发因子,收集并分析资料,拟定调查工作底图,以调查问卷的形式开展液化影响因素摸底工作,开展针对性的外业调查或辅以物探和钻探工作,得到土壤液化发育潜势实际材料图;其后借用常规地质灾害的评估方法,开展调查区域的易发性、易损性评价和风险评价,得到调查区风险区划图。利用此方法对积石山地震诱发的泥石流灾害进行验证,分析其液化灾害的地质环境背景、形成机理和危害特征,并对其发生的风险进行评价。文章首次提出土的液化作用及其次生灾害区域调查因子的选择和风险评估的流程,可为开展土层液化作用及其次生灾害隐患区排查、国土空间规划,特别是高烈度山区集中居住点地质安全评估和选址建议提供参考。

Comprehensive effects of traditional Chinese medicine treatment on heart failure and changes in B-type natriuretic peptide levels: A meta-analysis

BACKGROUND Heart failure(HF),a common cardiovascular condition,is characterized by significant morbidity and mortality.While traditional Chinese medicine(TCM)is often used as a complementary approach in HF management,systematic evalua-tions of its impact on clinical outcomes,TCM syndrome scores,and B-type natriuretic peptide(BNP)levels are lacking.This study fills this gap through a comprehensive analysis of randomized controlled trials(RCTs)focusing on TCM for HF treatment.It encompasses an assessment of methodological quality,a meta-analysis,and an evaluation of evidence quality based on established standards.The results offer crucial insights into the potential advantages and constraints of TCM in HF management.RCTs on TCM for HF treatment published since the establishment of the database were searched in four Chinese and English databases,including China National Knowledge Infrastructure,Wanfang,VIP Information Chinese Science and Technology Journal,and PubMed.Methodological quality was assessed for the included studies with the Cochrane risk-of-bias assessment tool,and the meta-analysis and publication bias assessment was performed with the RevMan5.3 software.Finally,the quality of evidence was rated according to the GRADE criteria.RESULTS A total of 1098 RCTs were initially retrieved.After screening,16 RCTs were finally included in our study,which were published between 2020 and 2023.These RCTs involved 1660 HF patients,including 832 in the TCM group[TCM combined with conventional Western medicine(CMW)treatment]and 828 in the CWM group(CWM treatment).The course of treatments varied from 1 wk to 3 months.TCM syndrome differentiation was analyzed in 11 of the included RCTs.In all included RCTs,outcome indicators included comprehensive clinical outcomes,TCM syndrome scores,and BNP levels.The meta-analysis results showed significant differences between the TCM and CWM groups in terms of comprehensive clinical outcomes[risk ratio=-0.54;95%confidence interval(CI)=-0.61,-0.47;P<0.00001],TCM syndrome scores[weighted mean difference(WMD)=-142.07;95%CI=-147.56,-136.57;P<0.00001],and BNP levels(WMD=-142.07;95%CI=-147.56,-136.57;P<0.00001).According to the GRADE criteria,RCTs where"TCM improves clinical comprehensive outcomes"were rated as low-quality evidence,and RCTs where"TCM reduces TCM syndrome scores"or"TCM decreases BNP levels"were rated as medium-quality evidence.CONCLUSION TCM combined with CWM treatment effectively improves comprehensive clinical outcomes and diminishes TCM syndrome scores and BNP levels in HF patients.Given the low and medium quality of the included RCTs,the application of these results should be cautious.

2022年7月2日皮山M_(S)5.1地震宏观异常调查与分析

以地震宏观异常现象的历史发展过程为出发点,具体描述和田地区皮山县震中周围动物震前、震后异常变化现象和特征。阐述了新疆和田地区皮山5.1级地震现场震中西南方向6~15 km村庄农户圈养的牛、羊等不同动物的反常现象,并针对在地震前后动物发生异常变化的18个调查点、98次异常进行详细统计。其中,皮山县乔达乡8个调查点7种动物宏观异常显著,异常数量总计46次;昆泉镇10个调查点4种动物宏观异常显著,异常数量总计32次。经统计,临近地震发生前24~36小时左右,狗、鸡、鸽、鸭反应异常显著,总宏观异常次数占比较高,动物主要表现为躁动不安、狂吠不止。由此分析得出:临震前,在不同时间段的11个调查点附近7种动物具有较明显的异常反应,从时间尺度上来看,离震中越近的地方,动物异常越早,异常动物数量、种类越多;反之越少。宏观异常现象具有向震中区域靠拢的趋势,空间分布较为集中。

An Investigation into the Case of Multi-interpretation in Poetry Translation

In translating poems, it is very common that different people have quite different versions of the same poem. This paper therefore intends to expound upon the underlying factors from the perspective of Hermeneutics,by exploring the relationship between the textual meaning and the textual significance of a poem, as well as the relationship between the author's intention and the textual intention of a poem, aiming to explain the key element in translating poems—multi-interpretation.

2013年四川芦山M_(S)7.0地震仪器烈度与调查烈度对比分析

基于2013年四川芦山M_(S)7.0地震宏观调查点、调查烈度和强震仪记录数据,采用四川省地震局强震动监测技术组计算得到的各台仪器烈度值,绘制了芦山M_(S)7.0地震宏观调查点与调查烈度等震线和仪器烈度等值线分布图,分析了芦山M_(S)7.0地震的仪器烈度与调查烈度的对应关系。结果表明:仪器烈度与调查烈度有较好的对应关系,仪器烈度Ⅵ度点在调查烈度Ⅵ度以上区域总体占比为88.24%,仪器烈度Ⅶ度点在调查烈度Ⅶ度以上区域内总体占比为81.82%;仪器烈度的等值线高值范围可较好展示出地震灾害的程度;仪器烈度区的空间分布特征可表征芦山M_(S)7.0的发震断裂的控制作用,仪器烈度的等值线区总体呈现沿龙门山断裂带方向相对于垂直方向衰减慢;仪器烈度的等值线区发震断裂上盘影响范围相对发震断裂下盘影响范围大;仪器烈度分布与调查烈度分布既有对应关系又存在差异,这在震后短时间内灾区的震灾信息尚不清楚的情况下,能够快速对可能的震害涉及范围、人员伤亡分布、经济损失和生命线工程等损失作出预估,仪器烈度分布可以为应急救援决策、救灾方案制定和救灾力量部署等工作提供重要依据。

我国16省份猪流行性腹泻病毒临床检测及基于S基因的遗传进化分析

为了解猪流行性腹泻病毒(porcine epidemic diarrhea virus,PEDV)在国内的流行与变异情况,本研究应用RT-PCR方法对2020—2021年采集的16省市共732份猪腹泻病料进行PEDV核酸检测,并对PEDV阳性样本进行S基因扩增、测序以及遗传进化分析。结果显示,2020—2021年采集的732份样本中489份PEDV阳性,阳性率为66.80%。获得76株PEDV S基因序列,遗传进化和核苷酸一致性分析显示71株为GⅡb型、5株为S INDEL型,毒株间核苷酸序列一致性为93.9%~100%。对贵州铜仁2020年2株和2021年3株S基因序列比对结果显示,2021年3株S基因序列一致性为100%,且与2020年的1株序列一致性为99.9%;对江苏盐城2020年2株和2021年2株S基因序列比对分析,其核苷酸一致性为97.6%~99.2%。对获得的76株S基因编码蛋白的氨基酸序列比对分析,与疫苗株CV777相比,71株GⅡb型毒株S基因序列与GII型代表株具有高度相似的遗传标记,包括在58~59位氨基酸之间存在4个氨基酸的插入,在139~140位氨基酸间存在1个氨基酸的插入;5株S基因序列除具有与S-INDEL型代表株相同的遗传标记外,在139~140位氨基酸间存在1个氨基酸的缺失,且在S蛋白N端存在多处连续突变;此外,ZJLS10-2021株、GXNN14-2021株与其他基因型相比分别在1267~1268位氨基酸之间存在1个氨基酸的插入,在379~383位氨基酸之间存在3个氨基酸的插入。研究结果表明,我国不同省市PEDVS基因具有易突变特性,同一地域主要流行毒株具有相对遗传稳定性。本研究为进一步监测和分析引起我国猪群腹泻的发生、流行、追踪和溯源及研究PEDV传播的途径和遗传变异规律提供了有力的数据支持,同时为猪腹泻病的防控和疫苗研发提供理论和技术参考。
