We read with great interest the study by Gao et al.¹ in which they demonstrated that a much larger back-rest inclination angle, approximately 15°, and a slight backward seat-pan, about 7°, may relieve the muscle fatigue and make driving more comfortable. In our opinion, there are some issues that should be addressed.

SUMMARY OBJECTIVE Psychological distress is an important mental health problem among university students. The goal of this study was to determine psychological distress and its associated risk factors among students in the Anhui province. METHODS A cross-sectional study was conducted in a sample of 1304 students. In this study, a self-administered questionnaire consisting of the general demography and General Health Questionnaire (GHQ-12) was completed. Psychological distress was assessed using the GHQ-12-item questionnaire. A dichotomous category split was imposed on the GHQ-12 for the purpose of analysis. A GHQ-12 score of 4 or higher indicated psychological distress. The data were analyzed by SPSS 20.0 system. RESULTS A total of 1304 samples were analyzed in this study. The results indicated that the education level of the father and mother was associated with the students’ psychological distress (P<0.001). A significant association was found between high-intensity exercise and low-intensity exercise and psychological distress. However, no significant difference was identified between gender and psychological distress (P=0.173). CONCLUSION The education level of parents, high-intensity exercise, and low-intensity exercise were associated with psychological distress. Our results suggest that it is indispensable to raise awareness of psychological disorders and its associated risk factors among university students. Further studies are required to develop appropriate interventions for high-risk groups.

Firstly, it is novel and innovative to use high-resolution MRI testing for plaque histology of patients with HoFH. Although the diagnostic accuracy of MRI is superior to CT in detecting thymomas, there is only one case included in present study² . Thus, more patients with HoFH should be recruited in future studies.

It was with great interest that we read the study by Daming Gu¹ and colleagues in which they demonstrated that anxiety can induce chronic pain by activating astrocytes in the anterior cingulate cortex region. The authors believe that the activation of astrocytes can induce chronic pain. In our opinion, more experiments are necessary to reach any conclusion.
