OBJECTIVE: To systematically evaluate the repairing effect of stem cells on facial nerve defects. METHODS: Articles regarding the regenerating effect of stem cells on facial nerves in animals were collected from the databases of Pubmed, Cochrane Library, Web of Science, Embase, Scopus, and CBM. Two professionals independently completed the article screening, data extraction, and bias risk assessment. RevMan 5.3 and random-effects models were used for the statistical analysis, and the results were presented in the form of mean differences (MD) with a 95%CI. The results of functional evaluation (vibrissae movement, facial paralysis) and histological evaluation (density of myelinated fibers, diameter of fibers, thickness of myelin sheath, G ratio) of facial nerve were Meta-analyzed. RESULTS: A total of 4 614 articles were retrieved from the 6 databases, and 15 of these articles were included in the Meta-analysis. For vibrissae movement and facial paralysis, the stem cell group scored significantly higher than the non-stem cell group (P<0.05). The density of myelinated fibers and thickness of the myelin sheath in the stem cell group were higher than those in the non-stem cell group (P<0.05). The G ratio in the stem cell group was smaller than that in the non-stem cell group (P=0.001). There was no significant difference in fiber diameter (P=0.08). CONCLUSIONS Stem cells have potential in promoting facial nerve regeneration.

Objective To understand the current situation of the use of psychotropic drug off-label prescribing for nonorganic sleep disorder patients,and to provide evidence for the development of the expert consensus on off-label prescribing of psychoactive drugs in psychiatry.Methods Patients discharged in 2017 with nonorganic sleep disorders were enrolled in the study.The off-labelled prescribing of psychoactive drugs questionnaire was used to investigate the records retrospectively.The off-label prescribing situation was confirmed by the drug label in China.Results A total of 294 patients were enrolled.The total rate of off-labelled prescription was 70.1％ (206/294),the rate of off-labelled indication was 68.4％ (201/294),the rate of off-labelled population was 14.3％(41/294),and the rate of off-labelled dose was 5.4％ (16/294).Conclusion Off-label usage of psychotropic drugs is common and to standarize off-label prescribing with close supervision should be considered.
