当前社会面临的一个重要问题是青少年肥胖,不仅影响个人的健康,也成为全球公共卫生领域的一大挑战。过去40年全球青少年肥胖显著增加,特别是在我国,青少年肥胖率增长速度超过全球平均水平。这一问题远超出单纯的体重增加,预示着未来可能暴发肥胖相关的心血管疾病、2型糖尿病和非酒精性脂肪肝病等一系列严重的健康风险。面对日益增加的青少年肥胖率以及可能对健康产生的严重影响,有效的早期干预和治疗显得尤为关键。本文旨在通过回顾青少年肥胖的研究和探讨当前的研究进展,如数字医疗技术和菌群治疗等,为未来构建更为有效的预防和治疗策略提供理论和实践思考。

秦汉帝国与罗马帝国的建立,反映了中西古代文明从小邦至地域性国家再至帝国的发展趋势。这一趋势是不以任何人的意志为转移的。秦汉帝国在民族关系、政治经济和思想文化方面采取了强有力的措施,将境内众多的民族和地区统一起来。罗马帝国则主要采用征服的手段进行统治。统一与征服表现出中西古代帝国内部结构上的重大区别。这一区别在秦汉与罗马帝国的形成过程中就有充分的反映。其更深层次的原因则在于中西历史文化传统存在较大的差异。中国文明的发展自古以来就有鲜明的、颇具特色的统一性,而这一特点是古代西方文明所没有的。

《尚书·无逸》载"高宗亮阴,三年不言"事,其中"亮阴"之义,在学术史上一直存在争议。学者们对"亮阴"之训释,或从文字训诂而达经义,或并举训诂义和史料训释经文。他们的文字训诂皆通且文从字顺,然而释义则大异。究其原因,就在于前贤解释经文所征引的史料皆缺乏准确的时间和空间定位。所以,前贤所出之说仅为可能成立的结论。在没有确凿史料可以解释"亮阴"之义的情况下,司马迁存而不议且传之以疑,确可为卓然之见。司马迁疑则传疑思想的形成,取决于他作为一位杰出史学家所具有的史学思想的自主性。这种自主性表现为史家思想的自由和建立在求真基础之上的自律。

郧县汉江大桥为主跨414 m的地锚式预应力混凝土双塔双索面斜拉桥,每塔两侧各布置50根斜拉索,跨中设置4个无轴力中间铰。该桥于1994年建成,2014年检测发现斜拉索破损严重,4个无轴力中间铰均出现一端卡死现象,主桥被评定为四类桥梁,需进行全桥综合维护。根据病害情况,先更换损坏严重的21根斜拉索;再按单塔对称、双塔反对称2根索同时更换的原则更换20~25号斜拉索;最后按双塔反对称4根索同时更换的原则更换1~19号斜拉索。全桥200根斜拉索更换后调整索力和梁体标高,采用拖拉法校正无轴力中间铰。无轴力中间铰校正后,在其端部和跨中断缝处安装监测系统,监测其工作状态。监测结果表明,无轴力中间铰能够纵向自由滑移,工作状态良好。

The mucus produced by the outbreak of Phaeocystis globosa in the adjacent waters of the Fangchenggang Nuclear Power Plant(FCGNPP) in China has blocked the entrance of the cooling water filtration system of the FCGNPP, and posed a threat to the safe operation of the FCGNPP. At present, there is no related research on whether the changes in seawater viscosity could be used as a new method for monitoring and providing early warning of P. globosa tide. During a complete red tide cycle, the temporal and spatial changes in the hydrological conditions(temperature, salinity, dissolved oxygen), chlorophyll-a(Chl-a), composition and abundance of phytoplankton, number and size of P. globose colonies, concentration of transparent exopolymer particles(TEP) and the seawater viscosity were measured in this study. The results indicate that there was an extremely significant negative correlation between the physical seawater viscosity η_(T,S) and temperature, and the correlation coefficient reached-0.998. The biological seawater viscosity η_(Bio) was positively correlated with the number of P. globosa colonies, and the correlation coefficients is 0.747. Because the increase in phytoplankton abundance, especially during the outbreak of P. globosa and a large amount of mucus produced by the colonies could significantly increase seawater viscosity, we suggest that biological factors were the main reasons for the increase in seawater viscosity. The η_(Bio) was completely consistent with the occurrence process of P. globosa bloom and could be used as a valuable index for P. globosa bloom monitoring.

Objective:To explore the best timing for frozen embryo transfer(FET)after ovarian stimulation and egg retrieval using the clomiphene citrate(CC)+human menopausal gonadotropin(hMG)ovulation induction regimen through a retrospective ***:Data of patients who underwent CC+hMG ovulation induction and FET from January 2014 to December 2019 were analyzed *** patients were divided into three groups according to the interval from egg retrieval to FET:CC1(within 1 menstrual cycle),CC2(2 menstrual cycles),and CC3(≥3 menstrual cycles).Indicators such as hormone levels and pregnancy outcomes were recorded to explore the effect of different intervals on pregnancy ***:A total of 1,082 transfer cycles were included in this retrospective *** implantation,clinical pregnancy,and live birth rates in the CC1 group were significantly lower than those in the CC2 and CC3 groups(P<0.05).The E2/P4 ratio on progesterone injection day(3 days before thawed embryo transfer)was lower in the CC1 group than in the other groups(P<0.05).After adjusting for all factors using multifactor regression analysis,the interval between egg retrieval and FET was found to be an independent predictor of the implantation,pregnancy,and live birth ***:An interval of more than one menstrual cycle between the day of egg retrieval after ovarian stimulation with the CC+hMG ovulation induction regimen and the day of FET can result in high implantation,clinical pregnancy,and live birth rates,which can lead to an improved pregnancy outcome.
