Objective: To investigate the presence of social anxiety and depression and the risk factors for them among primary school students who were quarantined at home during the coronavirus disease 2019 (COVID-19) epidemic in Hangzhou China.
Methods: A total of 1620 students who were quarantined at home for at least one month were recruited from two primary schools in Hangzhou. Students completed a questionnaire on a mobile App with help from their guardians; the measures included demographic and general information, the Social Anxiety Scale for Children (SASC), and the Depression Self-rating Scale for Children (DSRSC).
Results: The mean SASC score of the participants was 3.90±3.73, which was higher than the mean norm score of Chinese urban children (3.48±3.47) (P < 0.01). The mean DSRSC score of the participants (5.67±4.97) was much lower than the mean norm score of Chinese urban children (9.84±4.73) (P < 0.05). A total of 279 (17.2%) students had social anxiety, with a mean score of 10.41±2.59, and 102 (6.3%) students had depression, with a mean score of 18.96±3.89. The following variables were found to be significant risk factors for social anxiety during home quarantine: deterioration of the parent-child relationship, increased conflicts with parents, irregular work and rest, and worrying more about being infected. Deterioration of the parent-child relationship, less physical activity, irregular work and rest, and negative mood during home quarantine were significant risk factors for depression.
Conclusion: Primary school students who were quarantined at home during the COVID-19 epidemic were more likely to have social anxiety but less likely to have depressive symptoms. Poor parent-child relationships, irregularity of work and rest, and epidemic-related problems were the main reasons for psychological problems. Families, schools, and social organizations need to pay more attention to the psychological status of primary school students quarantined at home.
The basic fibroblast growth factor (bFGF) has a special role in improving proliferation and differentiation of fiber cells in growth of muscle. The function of bFGF with magnetic nanoparticles (MNPs) on regeneration and recovery of rats’ dampened skeletal muscle and expression
of MMPS were studied in our research. The MNPs packed with bFGF were prepared and 95 experimental rats were selected. These 30 rats were equally divided into control group, model group (self-healing without obstruction after model was established), bFGF group (disposed with bFGF packaged with
MNP). The contractility and stress relaxation of rats’ skeletal muscle were observed at the 48th h, 10th, 17th, 24th and 30th days after damage. The remaining 65 rats were divided randomly into control group (5 rats) and experimental group (60 rats intervened with MNPs packaged with
bFGF). The groups were randomly divided into 0.5 h, 1 h, 3 h, 6 h, 12 h, 1 d, 2 d, 3 d, 4 d, 7 d, 10 d and 14 d according to different executed time. The levels of bFGF and MMPS were detected by HE staining method and immunohistochemical staining. There was a significant declining tendency
of shrinkage stress of muscle in the model, sham-operation, BSA and bFGF groups compared with control group in the second day. The contractility after contusion wound in the regeneration and recovery of rats’ skeletal muscle was effectively alleviated with MNPs packaged with bFGF.
