Predictive value of gB2 antibodies for maternal–fetal transmission after primary cytomegalovirus infection treated with valacyclovir

open access: yesUltrasound in Obstetrics &Gynecology, Volume 67, Issue 4, Page 455-460, April 2026.
ABSTRACT Objective To estimate the residual risk of maternal–fetal transmission after primary cytomegalovirus (CMV) infection in the periconceptional period or the first trimester in women treated with valacyclovir, and to assess whether the presence of glycoprotein B2 (gB2)‐specific immunoglobulin (Ig)‐G antibodies on immunoblot analysis refines fetal

晶状体随年龄增长对眼前段轴向空间结构的影响

open access: yesZhongshan Daxue xuebao. Yixue kexue ban, 2007
【目的】探讨正常人晶状体随年龄的增长对跟前段轴向空间结构的影响。【方法】采用跟前段光学相干断层扫描仪(AS—OCT)测量正常人105例(105只眼)前房深度(ACD)和晶状体厚度(LT);比较它们性别间的差异,采用直线相关与回归分析方法分析年龄与ACD、LT的相关关系。【结果】正常人ACD、LT的平均值分别为:2.97(S=0.32)mm、4.21(S=0.43)mm。女性ACD为2.87(S=0.33)mm比男性3.07(S=0.29)mm浅(P=0.001);LT性别间差异无统计学意义(P=0 ...

Machine Learning Model for an App‐Based Tool to Assist With the Diagnosis of Canine Atopic Dermatitis

open access: yesVeterinary Dermatology, Volume 37, Issue 2, Page 236-246, April 2026.
Canine atopic dermatitis (cAD) is a chronic condition requiring life‐long management. Accurate diagnosis can be challenging, with no reliable diagnostic test. This study aimed to generate a simple diagnostic model for cAD. This model is a relevant prototype for an app‐based tool to support general practitioners in the diagnosis of cAD alongside ...

超声弹性成像技术评价2型糖尿病患者颈动脉和足背动脉血管壁弹性

open access: yesZhongguo shiyan zhenduanxue, 2014
目的利用超声弹性成像技术评价2型糖尿病(T2DM)患者颈动脉、足背动脉血管壁弹性的变化及与年龄的关系。方法研究对象分为T2DM组和对照组,各78人,使用高频线阵探头分别测量二组颈动脉、足背动脉内径(D),并用超声弹性成像技术对血管壁弹性进行评估,计算血管内血液与血管壁的应变率比值(B/A)。然后将二组的血管内径、B/A值进行比较分析。同时把T2DM组、对照组按年龄分为青年亚组,中年亚组及老年亚组,比较不同年龄段B/A值与年龄的关系。结果两组间颈动脉、足背动脉血管内径相似,差异无统计学意义(P>0.05);

年龄对动脉粥样硬化相关危险因素的影响

open access: yesZhongguo shiyan zhenduanxue, 2020
目的考察不同年龄段人群动脉粥样硬化(AS)相关危险因素水平及其致病风险。方法以2016年1月至2019年1月我院收治的AS相关疾病住院患者4089例为研究对象,分为中年组、老年组和高龄老年组。根据血管造影、CT血管成像或外周血管超声检查确立AS诊断。结果①年龄越大,动脉血管严重病变的比例越高。②高血压病、糖尿病的患病率均以老年组最高,显著高于中年组。③肥胖、血脂异常、吸烟、饮酒则是中年组最高,高龄老年组最低 ...
