[A Meta-analysis on the association between sleep duration and metabolic syndrome in adults].

Objective: To quantitatively evaluate the relationship between sleep duration and metabolic syndrome in adults in order to set up programs on prevention and treatment of metabolic syndrome in this population. Methods: Relevant studies were identified by systematically searching databases before October 2019. All statistical analyses were under the use of Stata 11.0. Results: A total of 656 319 participants including 150 638 cases with metabolic syndrome were involved in thes 38 articles. A U-shaped relationship between sleep duration and metabolic syndrome was noticed. For short and long sleep duration, the OR=1.11 (95%CI: 1.07-1.16) and 1.10 (95%CI: 1.03-1.18), respectively. Subgroup analyses on cross-sectional studies revealed that factors as men, aged under 60 years, being Asians or Caucasians would increase the risk of metabolic syndrome by 6%, 14%, 9%, and 24%, respectively for those with short sleep duration. Factors as aged 60 years and above, being black and with long sleep duration, would increase the risks of metabolic syndrome by 13% and 19%, respectively in women. In subgroup analyses on cohort studies, positive correlation between short sleep duration and metabolic syndrome was observed in both Asian (RR=1.10, 95%CI: 1.07-1.13) and in Caucasians (RR=1.56, 95%CI: 1.08-2.26) populations. Conclusions: Results of this study revealed an association between metabolic syndrome and the duration of sleep. We understand that sleep is a behavior that can be changed step by step, through adequate intervention programs, to reduce the risk of metabolic syndrome which has become an important public health issue.

[The curative effect analysis of 164 tinnitus patients with different types of hearing curve].

Objective:To investigate the difference of therapeutic effect of tinnitus patients with different types of hearing curve.Method:Patients with the inclusion and exclusion criteria for the treatment were studied retrospectively.Use the SPSS 20.0 Chinese version of the software to collect data and analysis.The difference was statistically significant when P<0.05.Result:A total of 164 patients were collected, and the most of the hearing curve types was high frequency hearing loss; according to the TEQ scoring and grading method, most tinnitus patients were in the middle severity; The chi-square test showed that there was no significant difference among the patients with different hearing curve types when the first visit,the severity among the groups was evenly distributed. After treatment,there was no significant difference in the effect of last visit and the follow-up between the patients with different hearing curve types.Conclusion：Unlike the sudden deafness, there was no statistically significant difference in the prognosis of tinnitus patients with different types of hearing curve. We can not choose the treatment program or even predict the curative effect according to the hearing curve type.
