Practice of blood donor emergency recruitment by TikTok / 中国输血杂志

【Objective】 To discuss the practice of emergency recruitment of blood donors through TikTok by shooting short videos, and evaluate the recruitment effect. 【Methods】 The completed short videos about blood donor emergency recruitment were released by major media official accounts on TikTok on New Year′s Day, May Day and National Day in 2022. Blood collection data within 10 days before and after the release were collected, and data within 7 days after the release were selected as the experimental group and the same period in last year as the control group to compare the blood collection units, donation frequency, gender and age of blood donors. 【Results】 The units of daily blood collection was the largest on day 1 after the release of TikTok short video, which was 3 times that of the previous day, and then decreased day by day, until to the same level as before the release on day 7. The daily blood collection, the proportion of first-time blood donors, donors aged 26 to 55 years old in the experimental group were all higher than those of the control group, but the proportion of blood donors aged 18 to 25 years old was lower than that of the control group. There was no significant difference in gender between the two groups. 【Conclusion】 Releasing short videos of blood donor emergency recruitment through TikTok, with fast dissemination and wild audience, can increase the blood inventory in a short time and is worthy of promotion.

The effects of short video app-guided loving-kindness meditation on college students' mindfulness, self-compassion, positive psychological capital, and suicide ideation

Abstract Objective The study investigated the effects of a short video app guided loving-kindness meditation (LKM) on college students' mindfulness, self-compassion, positive psychological capital, and suicide ideation. The purpose of the study is to investigate the intervention effect of LKM training on suicidal ideation among college students with the help of the short video application and to provide an empirical basis for the exploration of early suicide intervention strategies for college students. Methods We recruited 80 college students from a university in China. The final 74 eligible participants were divided into two groups: app use group (n = 37) and the control group (n = 37). The app group accepted an 8-week app use interference, while the control group underwent no interference. We measured four major variable factors (mindfulness, self-compassion, positive psychological capital, and suicide ideation) before and after the app use intervention. Results In the app group, self-compassion and positive psychological capital were significantly higher, and suicide ideation was significantly lower than the control group. In the control group, there were no noticeable differences in any of the four variables between the pre-test and post-test. Conclusions Our findings demonstrate that the short video app guided LKM may help to improve self-compassion, and positive psychological capital, and reduce suicide ideation. The finding of the short video app-guided LKM's effect extends our understanding of the integrative effects of positive psychology and digital media on the reduction of suicide ideation.

Latent categories of adolescents' short video media use tendency and their relationships with personality traits / 中华行为医学与脑科学杂志

Objective:To explore the latent categories of short video media use tendency among adolescents and the influence of personality traits on different categories.Methods:Totally 1 362 adolescents were tested by the five factors of adolescent personality questionnaire and the problematic short video media use scale in March 2022.SPSS 26.0 software was used for data collation and descriptive statistics.Mplus 8.3 software was used for latent profile analysis (LPA) to explore the latent categories of adolescents’ short video media use tendency.Regression mixed model (R3STEP) was used to explore the relationship between different categories of short video media use tendency and personality traits.Results:The short video media use tendency among adolescents was divided into 4 latent categories (by proportion from low to high): " problematic short video media use tendency type" (C4, 11%), " safe short video media use tendency type" (C3, 21%), " social short video media use tendency type" (C1, 29%), and " transitional short video media use tendency type" (C2, 39%). Different personality traits had different effects on the 4 latent categories of short video media use tendency, and using C3 as a reference, openness ( OR=1.95) was a triggering predictor of C1, neuroticism ( OR=0.72) was a protective predictor of C1; cautiousness ( OR=0.46) was a protective predictor of C2, neuroticism ( OR=1.60) was a triggering predictor of C2; cautiousness ( OR=0.33) was a protective predictor of C4, neuroticism ( OR=3.24) was a triggering predictor of C4. Conclusion:There are four different latent categories of Chinese adolescents' short video media use tendency, respectively " safe" , " social" , " transitional" and " problematic" . Further research reveal that, personality traits have a significant impact on the different categories of adolescents' short video media use tendency.This study suggests that educators reasonably guide " transitional" , intervene " problematic" , and focus on helping adolescents with high neuroticism to effectively regulate their negative emotions and reduce the occurrence of problematic short video use.

Application of JiTT model in comprehensive experimental teaching of biochemistry / 中华医学教育探索杂志

Objective To explore the method and effect of applying just-in-time-teaching (JiTT) mode in the reform of the teaching method of biochemical comprehensive experiment (Isolation, Purification and Identification of γ-Globulin From serum). Methods A total of 100 undergraduate students in our 2016 clinical medicine were divided evenly into two groups: the control group and the experimental group. The control group used traditional teaching, and the experimental group used JiTT-based teaching. In the experimental group, an online environment for pre-classroom discussion and feedback was constructed by uploading learning resources such as short video and tutorials to the online teaching platform and the online learning exchange group 3-5 days before the class; the class session itself consisted of personal tests, face-to-face teaching by teachers, group discussion, finishing experimental report and answering questions etc., and was intended to evaluate the students' self-study. SPSS 22.0 was used to collect exam scores and questionnaire results, and the data between groups were compared using t test. Results The scores of individual test scores in the experimental group (9.44±0.59) were higher than those in the control group (8.77±0.41) (P=0.00), and the difference was statistically significant. In all the six questionnaire items pertaining to teaching effect , JiTT teaching method received higher scores than the traditional teaching method (P<0.05), and the difference was statistically significant. Conclusion JiTT can improve the quality of biochemistry experiment teaching. It is worthwhile to try it in the teaching of other basic specialized courses.
