The acceptance of SARS-CoV-2 rapid antigen self-testing: A cross-sectional study in China

Compared with the nucleic acid amplification test (NATT), the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) rapid antigen self-testing (RAST) has advantages in speed and convenience. However, little is known about people's acceptance and influencing factors for SARS-CoV-2 RAST. A cross-sectional study was conducted from April 21 to 30, 2022 in China. The χ² test and multivariate logistic regressions were used to identify the influencing factors. The structural equation model was used to test the extended protective motivation theory (PMT) model hypotheses. Among the total of 5107 participants, 62.5% were willing to accept the SARS-CoV-2 RAST. There were significant differences in acceptance among different residences (p < 0.001), educational level (p < 0.001), occupation (p < 0.001), monthly income (p < 0.001), travel frequency (p < 0.05), and feelings about NATT (p < 0.001). Response efficacy (β = 0.05; p = 0.025) and self-efficacy (β = 0.84; p < 0.001) had a positive effect, while response cost showed a negative effect (β = −0.07; p < 0.001). The public's major concerns about SARS-CoV-2 RAST are its reliability, testing method, price, and authority. Overall, a moderate intention to use SARS-CoV-2 RAST was found among the Chinese population. The extended PMT can be used for the prediction of intention to accept the RAST. We need to take measures to increase people's acceptance of SARS-CoV-2 RAST.

19例黄色瘤影像分析

通过对１９例黄色瘤影像分析,认为其基本表现为颅骨多发性破坏和肺部网粟粒状浸润,５岁以上儿童有颅骨广泛破坏应首先考虑本病,并应常规摄胸片检查。分析认为,Ｘ线平片检查是认一病的主要手段,ＣＴ和ＭＲＩ可作为必要补充,ＭＲＩ对显示垂体腺的细胞微病变具有重要意义。

转基因食品与健康

转基因技术已被许多国家广泛用于生产转基因动物和农作物。转基因食品在其生产过程和内在品质方面都占有明显优势。但人们对其食用安全性却心存疑虑,近年来国际食品贸易也因此受到很大影响。世界各国及有关组织已经重视对转基因食品的安全性和营养价值进行评价,现正讨论制定转基因食品的国际安全,有的国家目前对这类食品实施食品标签的特殊标示管理。
