ABSTRACT
Objective@#To investigate parent-child conflict among primary and secondary school students and their parents, and to promote family harmony and mental health of children and adolescents during the COVID-19 pandemic.@*Methods@#An anonymous online survey was completed by 12 711 parents of primary and middle school students during mid-March, 2020. Emotional translation, coping style, parent-child conflict were collected and analyzed by grade.@*Results@#The incidence of parent-child conflict was emotional opposition (62.3%), verbal conflict (52.6%) and physical conflict (20.5%), respectively. About 38.1% of parents and 23.6% of students experienced negative emotions, such as anxiety and anger, and the students used coping styles that were more uniform than those of their parents. About 77.9% of families reported that they experienced different levels of parent-child conflict, which was mainly caused by child learning difficulties(45.6%), daily arrangements(22.1%), and the use of electronic devices(10.2%); compared with the previous year, about 31.4% of families reported an increase in the frequency of parent-child conflicts in the last month.@*Conclusion@#Parent-child conflict is highly prevalent in the families of primary and middle school students, and such conflicts were affected by stress-related factors, which included COVID-19. It s necessary to improve the provision of relevant mental health education and psychological assistance.
ABSTRACT
To investigate the role of platelet membrane glycoprotein (GP) Ib/Ⅸ/Ⅴ complex and its subunit GP Ibа in patients with hemorrhagic thrombopathy (HT), the expressions of GP lb/Ⅸ/Ⅴ complex and GP Ibа, defined as mean fluorescence intensity (MFI), were assessed by flow cytometry.The maximum aggregation of platelet was determined by turbidity method. These indicators were compared among 68 HT patients with the presenting complaint of hemorrhage, 33 well-controlled HT patients and 32 normal healthy subjects. The results showed that the MFI of GP lblIX/V complex and GP Ibct was markedly lower in HT patients with current hemorrhage than that in the healthy subjects, with difference being statistically significant (P<0.05). There was no significant difference in the expressions of GP lb/Ⅸ/Ⅴ complex and GP lbа between well-controlled HT patients and normal healthy subjects (P>0.05). It was concluded that the expression of GP Ib/Ⅸ/Ⅴ complex, the receptor of thrombin and yon Willebrand factor, was down-regulated in HT patients with current hemorrhage,which might result in the dysfunction of platelet aggregation and recurrence of HT.
