RESUMO
BackgroundInsomnia disorder has become a common disease in the current society. Cognitive Behavior Therapy for Insomnia （CBTI） is one of the non-drug treatment methods for insomnia disorder， but relevant studies of its effect on sleep quality and cognitive function of patients with insomnia disorder are limited. ObjectiveTo explore the effects of CBTI on sleep quality and cognitive function in patients with insomnia disorder， so as to provide references for non-drug treatment of insomnia disorder. MethodsA total of 47 patients with insomnia disorder were recruited as the study subjects. They all met the diagnostic criteria of the Diagnostic and Statistical Manual of Mental Disorders， fifth edition （DSM-5） and have visited Sichuan Mental Health Center from January 2021 to October 2022. The patients underwent CBTI for 6 weeks. Before the treatment， depression and anxiety symptoms were assessed using Hamilton Depression Scale-24 item （HAMD-24） and Hamilton Anxiety Scale （HAMA）. Sleep status and cognitive function were assessed using Pittsburgh Sleep Quality Index （PSQI） and Montreal Cognitive Assessment （MoCA） before and 6 weeks after the treatment. Spearman correlation analysis was used to examine the correlation between the reduction of PSQI score and the increase of MoCA score after treatment. ResultsAfter the 6-week treatment， the factor scores and total score of PSQI across 6 subscales （the sleep quality， sleep onset time， sleep time， sleep efficiency， sleep disorder and daytime dysfunction） were lower than those before the treatment， and the score differences were of statistical significance （t=5.569~15.290， P<0.01）. Both factor and total scores of MoCA across 6 items （visuospatial and executive， naming， attention， language， abstraction and memory） were significantly higher than those before the treatment with score differences reaching statistical significance （t=-11.273~-4.277， P<0.01）. Spearman correlation analysis demonstrated that there was a positive correlation between the decrease in PSQI total score and the increase in MoCA total score after the 6-week CBTI treatment （r=0.323， P=0.027）. ConclusionCBTI may help improve sleep quality and cognitive function in patients with insomnia disorders. The improvement of sleep quality after CBTI intervention may be related to the improvement of cognitive function. ［Funded by Scientific Research Project of Sichuan Provincial Health Commission （number， 19PJ216）］
RESUMO
This paper aims to analyze the clinical efficacy of cognitive behavioral therapy for insomnia （CBTI） in chronic insomnia treatment， with a view to providing a theoretical basis for promoting the clinical use of CBTI and providing a reference for the non-pharmacological treatment of chronic insomnia patients in China. Chronic insomnia is a common disorder， and CBTI has emerged as the first approach to treating chronic insomnia， so this review focuses on the current status， clinical efficacy， adverse effects， existed problems and management strategies of CBTI for chronic insomnia treatment from the perspectives of physiological mechanisms and neuroimaging.
RESUMO
Objective To study the possible molecular mechanism of IL-10 in promoting Chlamydia muridarum infection in mice. Methods C57BL/6 wild-type and IL-10 gene knockout ( IL-10-/-) mice were infected with Chlamydia muridarum. Indirect immunofluorescence assay was used to detect the growth of Chlamydia muridarum in the intestinal and genital tracts. The severity of genital diseases was assessed by hydrosalpinx scoring. Expression of IFN-γand IL-2 in blood was measured by ELISA. Re-sults Compared with the wild-type group, Chlamydia clearance in the intestinal and genital tracts of IL-10-/- mice was significantly faster, and the expression of IFN-γ and IL-2 increased significantly. In addi-tion, wild-type mice showed more serious hydrosalpinx. Conclusions IL-10 delays Chlamydia trachomatis clearance and promotes Chlamydia infection through inhibiting the expression of IFN-γ and IL-2, which ag-gravates hydrosalpinx.
RESUMO
Objective To establish a capillary electrophoresis method to separate ephedrine and psedudoephedrine. Methods RM-β-CD and HP-β-CD were set as additives. A capillary electrophoresis method was set up. The effects of types and concentrations of additives, the concentrations and pH values of buffered solution, running voltage and organic solvent on the separation of ephedrine and psedudoephedrine were investigated.Results Ephedrine and pseudoephedrine could be successfully separated by using either RM-β-CD or HP-β-CD as additives. When RM-β-CD was used as additive, the best separation conditions were as follows: separation voltage 10 kV, 25 mmol/L Tris-H3PO4 (pH 2.42), 20 mg/mL of RM-β-CD. Under the conditions, the resolution of ephedrine and pseudoephedrine was 1.56 and they were separated successfully within 13 min. When HP-β-CD was used as additive, the best separation conditions were as follows: separation voltage 10 kV, 25 mmol/L Tris-H3PO4 (pH 3.00), 50 mg/mL of HP-β-CD. Under the conditions, the resolution of ephedrine and pseudoephedrine was 2.73 and they were separated successfully within 15 min.ConclusionThis method is reliable, rapid and repeatable. It can be used as separation determination method for ephedrine and pseudoephedrine.
RESUMO
Autophagy is a cellular reaction to the changes of internal and external environmental pressure, and a degradation process of the material composition. Recent study has shown that autophagy is closely related to the quantity and insulin secretion of pan-creaticβcell. As a self-protection mechanism, the activation and regulation of autophagy are essential for maintaining the structure and function of pancreaticβcells in type 2 diabetes. Moreover, some drugs for type 2 diabetes were found to participate in the regulation of autophagy pathway in recent studies. Thus, in this review we summarize the importance of autophagy in protecting the structure and func-tion of pancreaticβcell, the regulation of autophagy pathway and the correlation between autophagy and drugs for type 2 diabetes.
