Meeting 24-h Movement Guidelines is Related to Better Academic Achievement: Findings from the YRBS 2019 Cycle

This research is designed to investigate the relationship between the 24-h movement guidelines (24-HMG) and self-reported academic achievement (AA) using nationally representative data derived from the 2019 U.S. National Youth Risk Behaviour Survey. A multiple-stage cluster sampling procedure has been adopted to ensure a representative sample (N = 9127 adolescents; mean age = 15.7 years old; male% = 49.8%). Logistic regression has been adopted to obtain the odds ratio (OR) regarding the associations between adherence to 24-HMG and AA while controlling for ethnicity, body mass index, sex and age. The prevalence of meeting the 24-h movement guidelines in isolation and combination varied greatly (physical activity = 23.3%, screen time = 32.5%, sleep = 22.3%, and 24-HMG = 2.8%), while the percentage of highest-class AA was 42.5%. Compared with the situation when none of 24-HMG is met, the achievement of any of the combined guidelines (except for meeting the physical activity guidelines) was significantly associated with higher odds of achieving first-class AA. Meeting the sleep guideline had 1.42 times increased likelihood to achieve highest-class AA as compared with not meeting the sleep guideline. Meeting screen time guidelines and physical activity guidelines, respectively, were 1.32 and 1.13 times more likely to report first-class AA; but meeting the guidelines of physical activity was not significantly related to AA. Meeting the 24-HMG had the highest odds of achieving first-class AA (OR = 2.01, 95%CI: 1.47– 2.73). In both sexes, adolescents who met 24-HMG self-reported better AA (boys OR = 2.05, 95%CI: 1.34–3.15; girls OR = 2.26, 95%CI: 1.36–3.76). Significant relationships were observed in adolescents from 9–10th grade, but not higher grades.

2 μm激光整块切除与电切治疗非肌层浸润性膀胱癌的临床分析

目的:比较2 μm激光整块切除与电切治疗非肌层浸润性膀胱癌的有效性及安全性。方法:回顾性分析2015年4月-2017年4月分别采用经尿道2微米激光整块切除(50例)和经尿道电切(48例)治疗非肌层浸润性膀胱癌患者临床随访资料。结果:所有患者手术均顺利完成，激光组与电切组患者手术时间相当，两组比较差异无统计学意义(P>0.05)，激光组患者留置尿管、膀胱冲洗及住院时间均少于电切组，比较差异有统计学意义(P<0.05)；激光组患者并发症发生率、一年复发率及术区复发率低于电切组，两组比较差异均有统计学意义(P<0.05)；激光组术后病理含肌层率高于电切组，两组比较差异有统计学意义(P<0.05)。结论:经尿道2微米激光整块切除治疗非肌层浸润性膀胱癌是一种安全、有效的治疗方式且术后肿瘤分期精确、减少肿瘤残留，是治疗非肌层浸润性膀胱癌较好的手术治疗选择，值得临床上推广应用。     

饮用水水源地水中总铀浓度监测结果分析

目的 调查各种类型饮用水水源地水样中的总铀含量，分析饮用水水源地水体中总铀浓度、摄入量及其所致年待积有效剂量，为辐射环境安全监管提供科学依据。方法 通过现场采样，采用激光荧光法分析水中铀浓度，统计2010—2018年饮用水水源地水样总铀含量，计算年摄入量和年待积有效剂量。结果 监测分析结果显示，2010—2018年饮用水水源地水中总铀浓度为0.09～4.50 μg/L，所致公众总铀年摄入量儿童和成人的最大值分别为62.58 Bq、125.16 Bq，对应的年待积有效剂量分别为4.63 μSv、6.13 μSv，符合公众年待积有效剂量限值要求。结论 近岸海水的总铀浓度相对较高，湖库水和地下水的总铀含量较低且保持稳定，近海口的地表水总铀浓度有时偏高，可能是受潮汐影响。考虑公众影响，应制定铀元素的浓度限值标准。

保留前列腺尖部对绿激光前列腺汽化术后患者疗效的影响

目的探讨保留前列腺尖部对绿激光前列腺汽化术后患者疗效的影响。方法98例入组患者随机分成A组和B组,A组行绿激光治疗,保留超过精阜的前列腺尖部;B组在A组基础上继续行等离子电切除尖部前列腺组织,比较两组患者手术情况、疗效和并发症。结果B组手术时间、出血量高于A组(P<0.05),留置尿管和住院时间长于A组(P<0.05),而两组在术后8周国际前列腺症状评分(IPSS)、生活质量评分(QOL)、最大尿流率(Qmax)和残余尿(PVR)差异没有统计学意义(P>0.05)。结论在行经尿道前列腺绿激光汽化术时可以以精阜水平为界,超过精阜水平的远端腺体组织保留,而不影响术后早期排尿改善情况及生活质量。     

乌司他丁对冠状动脉搭桥术后患者认知功能障碍的影响

目的探讨不同剂量乌司他丁对冠状动脉搭桥术患者术后认知功能障碍的影响及其可能的作用机制。方法选择2013年1月至2014年6月在南京医科大学附属南京医院就诊择期行冠状动脉搭桥术的老年患者127例, 分为三组:大剂量乌司他丁组(1.6万U/kg)、小剂量乌司他丁组(0.8万U/kg)和对照组(等容量的生理盐水)。所有患者在手术当日和次日晨8时测血浆皮质醇浓度, 并在术前、开胸、术毕、术后6 h和术后24 h分别检测IL-6、IL-10、TNF-α和S100β蛋白水平。术前1 d、术后1周和3个月分别应用精神神经测试组合量表评估患者认知功能的变化判定有无术后认知功能障碍, 计算各组患者术后认知功能障碍的发生率, 并且比较术后1周是否发生术后认知功能障碍患者S100β蛋白水平。结果最终93例患者完成研究, 三组患者一般资料比较差异均无统计学意义(均 P>0.05)。与术前相比较, 对照组患者术后24 h血浆皮质醇浓度升高明显( P < 0.01), 且大剂量和小剂量乌司他丁组患者术后血浆皮质醇浓度均较对照组低(均 P < 0.01);三组患者术毕、术后6 h和24 h血浆IL-6、IL-10、TNF-α水平及S100β蛋白水平均高于术前(均 P < 0.05);大剂量和小剂量乌司他丁组患者在术毕、术后6 h和24 h血浆IL-6、TNF-α水平浇以及在术后6 h S100β蛋白水平均比相对应时间点的对照组患者降低(均 P < 0.05), 但大剂量和小剂量乌司他丁组患者组间差异无统计学意义( P>0.05)。大剂量和小剂量乌司他丁组患者术后1周认知功能障碍发生率(25.8%和23.3%)均低于对照组(50.0%), 差异有统计学意义(均 P < 0.05);而大剂量和小剂量乌司他丁组术后3个月的术后认知功能障碍发生率(12.9%和16.7%)与对照组(28.1%)比较, 差异均无统计学意义( P>0.05)。术后认知功能障碍组( n=31) 在术后24 h血清S100β蛋白水平高于非术后认知功能障碍组( n=62), 其差异具有统计学意义( P < 0.05)。 结论乌司他丁可降低冠状动脉搭桥术患者术后1周的术后认知功能障碍的发生率, 其机制可能与减轻炎性反应及脑损伤有关。
