SnO\-2 prepared with the sol-gel technique at different temperatures was used as an anode material of the lithium-ion battery. We obtained the qualititave relationship between the electrochemical performance of tin oxide anode material and each of its carbon component, particle size, structure and surface morphology in detail. It was found that the best electrochemical performance can be reached by controlling the physical characteristics of SnO\-2, which was affected greatly by the treatment temperature. The SnO\-2 obtained at 600 ℃ was pure. When it was used as the anode material of the lithium-ion battery, it demonstrated a high initial specific capacity of 770 mA\5h/g.

目的探讨代谢综合征的生物标志物及影响因素,构建代谢综合征的风险预测模型。方法选取2020年1月至2021年12月到某中心疗养体检并诊断为代谢综合征的161例患者作为实验组,另选择同一时期根据性别和年龄匹配的192例非代谢综合征患者作为对照组。收集患者的临床基线资料和生物标志物,利用Lasso回归筛选出代谢综合征相关的生物标志物,用于构建预测代谢综合征高危人群的预警模型。结果使用Lasso回归共筛选出7个影响代谢综合征相关的生物标志物和影响因素,分别为体质量指数(body mass index,BMI)、2型糖尿病(type 2 diabetes,T2DM)、空腹血糖(fasting blood glucose,FBG)、三酰甘油(triglyceride,TG)、高密度脂蛋白胆固醇(highdensity lipoprotein cholesterol,HDL-C)、单核细胞计数/高密度脂蛋白胆固醇比值(monocyte count/HDL-C ratio,MHR)和超敏C反应蛋白(high-sensitivity C-reactive protein,hs-CRP)。预测模型的曲线下面积(area under curve,AUC)为0.9857。结论本研究利用Lasso回归构建生物标志物的风险预测模型用于预测代谢综合征的能力较强,可用于指导临床医生早期识别代谢综合征的高危人群。

以阿尔金山国家级自然保护区内湖泊为研究对象,通过对大比例尺地形图和中高分辨率遥感影像的配准和目视解译,并结合保护区周边4个气象站1970−2021年气温、降水、蒸散量数据,系统分析了区内面积>1 km2湖泊的面积变化及其对气候因子的响应.结果表明:1)近51 a保护区的湖泊呈现扩张、稳定和萎缩3种变化趋势,但大部分湖泊处于扩张状态.其中:大型湖泊均呈扩张之势,并以20世纪90年代中期为节点,前期扩展缓慢,后期出现明显扩展增速;中型湖泊面积变化呈现扩张、稳定和萎缩3种趋势;小型湖泊面积变化呈现扩张和萎缩2种趋势;湖泊面积的变化趋势与湖泊自身的规模无关,只与其补给和支出平衡有关.2)沙子湖、小沙子湖是部分河段被沙埋的流经湖,多年湖面积变化较小,湖泊周围沙丘未出现大范围朝湖向移动.3)保护区湖泊的面积与气温和降水呈正相关,与蒸发量呈显著负相关,气温和降水对湖泊面积的影响大于蒸发.保护区内湖泊属降雨和冰川融水补给型湖泊,且冰川融水的补给量大于降水.研究结果有助于了解该地区气候变化控制下水资源演变过程,可作为进一步评估区域气候变化和湖泊变化的依据.

目的:分析前列腺癌根治术后膀胱过度活动症(overactive bladder, OAB)的发生及转归情况,并探讨其相关危险因素。方法:选择北京大学第三医院2013年1月至2017年5月住院接受根治性前列腺切除术的263例患者进行回顾性研究,分析并收集患者临床基线信息、计算影像特征、围术期参数、术前患者尿控情况、病理学诊断与术后1年内OAB发生情况的相关性。在影像特征中,定义膀胱壁厚度(bladder wall thickness, BWT)和膀胱黏膜光滑程度(bladder mucosal smoothness, BMS)两个参数,用于预测OAB的发生情况。结果:263例前列腺癌根治术后患者中,术后1年存在OAB状态者共52例,占所有患者的19.8%。术前既往存在OAB症状者40例,术后缓解者17例(42.5%),症状持续者23例(57.5%);术后新发OAB者29例,占术后所有OAB患者的55.77%。单因素分析显示膀胱壁厚度、膀胱黏膜光滑程度、膀胱过度活动症状评分和国际前列腺症状评分均与术后OAB的发生相关。进一步多因素分析发现,BMS是远期OAB的独立危险因素(P<0.001)。结论:根治性前列腺切除术后远期膀胱过度活动症是临床常见的并发症,通过术前磁共振成像测量充盈状态下膀胱壁厚度或膀胱黏膜光滑程度,可以预测根治术后OAB的发生风险。

部分生态系统在现代社会经济发展过程中遭到了不同程度的破坏,而生态风险评价是对生态系统健康状况最重要的衡量方法之一。以云南省为研究区,选取4类主要风险源,划分5类生境,以生态系统为风险受体,4类生态系统服务为评价终点,采用相对风险模型(relative risk model, RRM),分别计算云南省各生境、风险源、评价终点及评价单元的生态风险值,并划分风险等级;利用蒙特卡洛模拟方法进行不确定性分析,并结合评价结果进行风险管理分析。结果表明:云南省生态风险整体状况良好,空间差异较小;昭通市的相对风险等级最高,但结果误差最大;城市生态系统生境受到的风险、人口负荷风险源对生态系统造成的风险、调节服务对生态风险的响应,三者评价结果均为最高;风险源的不确定性对风险结果的影响存在低估现象,且风险演变模拟结果趋向收敛。
