扬子陆块西缘寒武系主要为一套碎屑岩-碳酸盐岩的岩石组合,前人研究多认为形成于相对稳定的克拉通盆地。但同时期出现的大陆岩浆作用显然与前期认定的克拉通盆地性质不符,需要借助扬子西缘的物质来源探讨构造背景。基于野外露头等资料,... 详细信息

扬子陆块西缘寒武系主要为一套碎屑岩-碳酸盐岩的岩石组合,前人研究多认为形成于相对稳定的克拉通盆地。但同时期出现的大陆岩浆作用显然与前期认定的克拉通盆地性质不符,需要借助扬子西缘的物质来源探讨构造背景。基于野外露头等资料,本文通过对扬子陆块西缘会泽和会东附近寒武系3件砂岩样品进行重矿物分析、电气石电子探针和碎屑锆石U-Pb测年分析,确定扬子西缘寒武纪沉积物的源区;并结合沉积序列等综合探讨扬子陆块西缘寒武纪的构造背景。沉积序列表明,扬子西缘寒武系沧浪铺组、西王庙组和二道水组主要由砂岩和白云岩等组成,沉积环境为滨岸—潮坪。细—粗砂岩碎屑颗粒为次棱角状—次圆状,分选较差;碎屑组分主要为石英,岩屑几乎全部为燧石,长石含量较少。测试分析结果表明:重矿物分析指示扬子西缘寒武系砂岩重矿物主要由锆石、赤—褐铁矿、电气石、钛铁矿、金红石、磷灰石等组成,重矿物组合指示岩浆岩为其主要母岩;电气石电子探针分析结果表明,物源主要来自于贫锂花岗岩和变砂岩、变泥岩;碎屑锆石测年分析表明物源区母岩主要为983~540 Ma岩浆岩。碎屑锆石年龄对比等综合分析表明,寒武系沉积物部分源自康滇古陆983~708 Ma的岩浆岩和变沉积岩,部分源自冈瓦纳大陆东非造山带663~540 Ma的岩石,物源区岩石经历再旋回产物作用。扬子西缘寒武系的沉积序列、碎屑锆石年龄谱图和碎屑组成等特征综合分析表明,扬子陆块西缘寒武系形成于前陆盆地。

当前公安机关未保工作中存在娱乐场所、酒店住宿业、网络空间等管理、治理不到位,打击惩处侵害未成年人的犯罪及矫治教育问题未成年人不到位等问题。诱发这些问题的因素有基层社会对未成年人保护问题重视不够等外部因素,也有公安机关未成年人保护机制不够健全、民警未成年人保护工作意识和能力欠缺等。需外部强化宣传提高认识形成全社会未成年人保护共识、完善机制,健全未成年人保护机构、培养未成年人保护工作人才、扎实推进各项未成年人保护工作等。

目的:探讨妊娠期糖尿病(GDM)孕妇新生儿不良结局高危因素并建立logistic风险模型。方法:选取2020年2月-2022年8月本院产科门诊接收的GDM孕妇196例临床资料,依据新生儿结局分为不良组、良好组。采用logistic回归分析明确GDM孕妇发生不良新生儿结局高危因素,建立logistic风险模型,采用Hosmer-Lemeshow检验判定风险模型拟合优度,受试者工作特征(ROC)曲线探讨风险模型的预测效力。结果:最终纳入的168例孕妇中出现不良新生儿结局44例、未出现124例。不良组与良好组妊娠期高血压疾病、抑郁症状、孕前BMI、孕期增重情况、空腹血糖(FPG)、服糖后1 h血糖(1 h PG)、分娩前糖化血红蛋白(HbA1c)有差异;logistic回归分析显示,妊娠期高血压疾病、抑郁症状、孕期增重过度、分娩前HbA1c水平高均为GDM孕妇发生不良新生儿结局独立危险因素(均P<0.05)。基于独立危险因素建立logistic风险模型,Logit(P)=-15.610+1.472×妊娠期高血压疾病(有=1,无=0)+0.884×抑郁症状(有=1,无=0)+1.014×孕期增重情况(孕期增重过度=2,孕期增重不足=1,孕期增重正常=0)+2.053×分娩前HbA1c(%),Hosmer-Lemeshow检验(χ^(2)=9.952,P=0.268)拟合优度良好。ROC曲线显示,logistic风险模型预测GDM孕妇发生不良新生儿结局的曲线下面积为0.792,95%CI 0.707~0.877,最佳预测敏感度77.3%,预测特异度72.6%。结论:GDM孕妇不良新生儿结局高危因素包括妊娠期高血压疾病、抑郁症状、孕期增重过度、分娩前HbA1c水平高,应用其建立的logistic风险模型预测效力较好,为临床干预提供参考。
