血清TRAb IgG亚型在甲状腺相关性眼病患者中的特征及临床意义

目的探讨血清TRAb IgG各亚型在不同活动分期甲状腺相关性眼病(thyroid-associated ophthalmopathy,TAO)患者中的分布特点,及其在评估TAO活动度中的价值。方法选取2018年8月至2019年2月郑州大学第一附属医院收治的TAO患者43例,依据临床活动度评分(clinical activity score,CAS)进一步分为活动期组(AP组,CAS≥3分,22例)和静止期组(IP组,CAS<3分,21例);Graves病患者(GD组)30例,桥本甲状腺炎患者(HT组)19例,并以同期健康体检者(NC组)50名作为正常对照。收集各组受试者临床基本资料,化学发光免疫法检测血清FT3、FT4、TSH、甲状腺过氧化物酶抗体(TPOAb)、甲状腺球蛋白抗体(TgAb)、促甲状腺激素受体抗体(TRAb)水平,酶联免疫吸附法检测血清TRAb IgG和IgG各亚型的百分结合率[binding rate in percentage,(B)],比较各亚型的阳性率和阳性亚型的相对含量。结果(1)与HT组相比,TAO组、GD组IgG1、IgG2阳性率降低,差异有统计学意义(P<0.05)。各疾病组间TRAb IgG亚型相对含量无明显差异(P>0.05)。(2)与IP组相比,AP组IgG1(B)、IgG1阳性率显著升高,IgG4(B)、IgG4相对含量显著降低(P<0.05)。(3)IgG1(B)与TAO活动度呈正相关(B=6.190,P=0.007),IgG4(B)越高越倾向于静止期,但差异无统计学意义(B=-16.390,P=0.052)。(4)活动率评估TAO处于活动期的受试者工作特征(ROC)曲线下面积为0.859(95%CI 0.746~0.973,P<0.05),当活动率为4.29时,约登指数最大,其判断敏感度为81.8%,特异度为81.0%。结论在TAO患者中血清TRAb IgG1水平升高提示疾病趋向活动期,IgG4水平升高提示疾病趋向静止期。活动率可为评估TAO是否处于活动期提供参考依据。     

Does it matter who’s at risk?: Testing message framing and narrative as moderators of the effects of self-referencing in obesity prevention messages targeting Hispanic adults living in the U.S.

Abstract

This study tested whether the effect of self-referencing in a health-marketing message was amplified or attenuated when combined with message framing and narrative. Hispanic adults (N?=?146) were randomly assigned to read and respond to an obesity prevention message. Self-referencing messages generated greater cognitive elaboration but only when placed in a narrative. Conversely, self-referencing messages highlighting health risks of obesity produced higher levels of involvement and intention to increase physical activity and healthy eating. Health marketing professionals can use these findings to enhance the effectiveness of obesity prevention messages that target Hispanic adults.     

Variation of circadian activity rhythm according to body mass index in children

Background/objectivesThis study aimed to examine the variations of circadian activity rhythm of children according to objective body mass index (BMI) values, using a novel statistical framework (ie, Functional Linear Modeling, FLM), separately for school- and weekend days.MethodsA total of 107 participants (60 females; mean age: 10.25 ± 0.48 years) wore an actigraph for seven days during a regular school-week. While valid actigraphic data during school days were available for each of these children, this number decreased to 53 (31 females; mean age: 10.28 ± 0.51 years) during weekend days.ResultsExamining the school days, significantly higher motor activity in participants with higher BMI was observed from around 4:00 a.m. to 6:00 a.m., with a peak about 5:00 a.m. On the contrary, applying the FLM to the weekend days actigraphic data, no significantly different variation of circadian activity rhythm was observed, according to BMI.ConclusionsIn this specific sample of children, during school days, higher BMI is associated with higher activity level in a specific time window in the second half of nocturnal sleep. The lack of significant findings during weekend days could be explained because of higher variability of get-up time and/or the reduced sample size. Future longitudinal studies could explore if the higher motor activity in that specific time window qualifies as a predictive marker of the development of overweight and obesity. If so, early preventive strategies directed towards those at higher risk could be effectively implemented.     

水提取法和仿生提取法研究菲牛蛭不同炮制品的体外抗凝活性

目的:采取不同的提取方法研究菲牛蛭炮制前后抗凝活性变化。方法:分别采用水提取法及模拟胃肠道环境的仿生提取法提取菲牛蛭活体冻干品、清水吊干品、滑石粉烫制品、酒浸闷烘品中的活性成分,测定活化部分凝血酶时间(APTT)、凝血酶原时间(PT)、凝血酶时间(TT)、抗凝血酶活性4个凝血指标,并采用Lorry法测定其蛋白含量,综合评价2种提取方法下的菲牛蛭及其炮制品的抗凝活性。结果:无论是水提取法,还是仿生提取法,APTT、PT、TT均显示炮制后抗凝活性降低,抗凝活性顺序为活体冻干品>清水吊干品>酒浸闷烘品>滑石粉烫制品,此结果与抗凝血酶活性及蛋白含量顺序一致。结论:高温炮制方法会降低菲牛蛭的抗凝活性。
