This study aimed to explore the association between mental health knowledge level and the prevalence of depressive symptoms among Chinese college students. A cross-sectional study was conducted in six universities in Jinan, Shandong Province, China, and a total of 600 college students were recruited to self-complete a series of questionnaires. The Mental Health Knowledge Questionnaire (MHKQ) was used to investigate the level of mental health knowledge. Depressive symptoms were investigated with the depression subscale of the Depression Anxiety Stress Scale (DASS-21). The prevalence rate of depressive symptoms among college students was 31.2%. Compared with MHKQ scoring in the 1st quartile, college students with MHKQ scoring in the 3rd quartile and in the 4th quartile reported lower levels of depressive symptoms after adjusting for potential confounding factors. Since mental health knowledge level was related to depressive symptoms among college students, increased efforts to promote the level of mental health knowledge in Chinese college students are critical.

In this study, we explore the sleep disorders and its associated factors in patients with Guillain-Barré syndrome (GBS), so as to work out appropriate interventions to promote early recovery of the patients. This study subjects included 49 patients with GBS who had been admitted to the Department of Neurology at The Affiliated Hospital of Hebei University, fulfilling National Institute of Neurological and Communicative Diseases and Stroke (NINCDS) criteria for GBS; 37 cases were male and 12 female (age: 27-68 years). Patients were evaluated once daily for two consecutive weeks. By using Wong and Baker Face Scale (WBFS) to evaluate the numbness and pain in patients, 0 points representing completely no pain and 10 points represents the most severity of the pain reactions; the same applies for numbness. The GBS Disability Scale (GBS DS) is used to evaluate the severity of GBS. The Hospital Anxiety and Depression Scale (HADS) is used to evaluate the anxiety and depression the patient is experiencing. All patients take routine EMG and sleep EEG. The sleep quality of the subjects was evaluated by the Pittsburgh Sleep Quality Index Scale (PSQI) and Richard Campbell Sleep Rating Scale. This study found that the application of ventilators, numbness, anxiety and severe limb movement disorders are the main factors causing sleep disorders. Cerebrospinal fluid (CSF) protein concentration is also associated with sleep disorders. But, no obvious abnormalities were found in sleep EEG. The application of the ventilator, numbness, anxiety and severe limb movement disorder are main factors causing sleep disorders. CSF protein concentration is also associated with sleep disorders.

The golden-crowned sifaka, Propithecus tattersalli, is a critically endangered social lemur species that inhabits the restricted and highly fragmented semi-evergreen forests. In this study, we determined the complete mitochondrial genome sequence of this species for the first time. The results shows that this mtDNA genome is 17 099 bp in size, and comprises 22 transfer RNA genes, 13 protein-coding genes, two ribosomal RNA genes, and one control region (D-loop). The overall base composition in descending order is A (32.91%), C (27.07%), T (27.04%), and G (12.98%), so the percentage of A and T (59.95%) is slightly higher than that of G and C. The gene order and the composition of P. tattersalli mitochondrial genome are exactly similar to those of most other vertebrates. All the genes are encoded on the heavy strand with the exception of NADH dehydrogenase subunit six (ND6) and eight tRNA genes. Phylogenetic analysis suggests that the P. tattersalli exhibits most close relationship with P. coquereli. The complete mitochondrial genome sequence presented here will be useful for further phylogenetic analysis and conservation genetic studies in P. tattersalli.
