Major antidepressants for the treatment of depression have several shortcomings such as delayed therapeutic action, limited remission rate and various adverse effects. Psychedelics are a group of psychoactive substances that can improve perception, mood and cognition. An increasing body of evidence shows that psychedelics positively promote individual social functioning and have a rapid and sustained improvement in moderate or severe depression. Therefore, the antidepressant effects of psychedelics have gained increasing attentions in recent years. This review summarizes the progress of research on the antidepressant effects of some representative psychedelics and their potential mechanisms of antidepressant action, and discusses the risks of clinical application of psychedelics.

INTRODUCTION: We aimed to compare the early clinical manifestations, laboratory results and chest computed tomography (CT) images of COVID-19 patients with those of other community-acquired pneumonia (CAP) patients to differentiate CAP from COVID-19 before reverse transcription-polymerase chain reaction results are obtained. METHODS: The clinical and laboratory data and chest CT images of 51 patients were assessed in a fever observation ward for evidence of COVID-19 between January and February 2020. RESULTS: 24 patients had laboratory-confirmed COVID-19, whereas 27 individuals had negative results. No statistical difference in clinical features was found between COVID-19 and CAP patients, except for diarrhoea. There was a significant difference in lymphocyte and eosinophil counts between COVID-19 and CAP patients. In total, 22 (91.67%) COVID-19 patients had bilateral involvement and multiple lesions according to their lung CT images; the left lower lobe (87.50%) and right lower lobe (95.83%) were affected most often, and all lesions were located in the peripheral zones of the lung. The most common CT feature of COVID-19 was ground-glass opacity, found in 95.83% of patients, compared to 66.67% of CAP patients. CONCLUSION Diarrhoea, lymphocyte counts, eosinophil counts and CT findings (e.g. ground-glass opacity) could help to distinguish COVID-19 from CAP at an early stage of infection, based on findings from our fever observation ward.

Objective To investigate the current situation of the knowledge,attitude and practice of diabetic foot self-care in elderly outpatients with diabetes,and to explore the effective methods of preventing diabetic foot in these population.Methods The study investigated 252 elderly outpatients with diabetes using convenient sampling.Self-designed questionnaires were used to investigate demographics data,and the knowledgeattitude-practice scores of preventing diabetic foot in elderly diabetic patients.The data would been analyzed.Results The average scores of knowledge,attitude and practice of self-care on preventing diabetic foot were respectively (4.74 ± 1.565),(17.69 ± 4.256) and (26.58 ± 4.899).Besides,the scores of the self-protection attitude and the self-protection practice had positive correlation (P ＜ 0.001).Conclusions Elderly outpatients with diabetes have poor knowledge but positive attitude towards self-care of preventing diabetic foot.Moreover,more universal training and education should be conducted,especially for migrant workers,due to their poor behaviors of self-care.

Objective To investigate compliance of breast cancer patients with postoperative peripherally inserted central catheter (PICC) in terms of upper limb motion, to formulate practical plan of upper limb motion, and to improve the compliance in the patients with PICC catheter.Methods A total of 75 patients after breast cancer operation with PICC for chemotherapy were selected from Department of Thyroid and Breast Surgery for upper limb activity instructions.Plan-Do-Check-Act method was used to evaluate the feasibility and effectiveness.Two cycles were performed in two weeks.Patients' compliance was assessed by the inquiry method.Results After practicing and refining nursing process, perfecting the risk assessment table, adjusting the education time, etc., the cognition and acceptance of the significance of upper limb motion were improved in the patients.The compliance of the patients to the upper limb motion instructions was satisfactory.Conclusions The upper limb motion scheme in this study was modified and perfected through application, research, and practice.This scheme could enhance the compliance of patients in terms of upper limb motion.
