Objective To investigate the brain protective effects of isoflurane preconditioning for local cerebral is-chemia adult rat model by detecting HIF-1α, HO-1 and Bcl-2 expression level. Methods 84 two-month old Spra-gue-Dawley male rats were randomly divided into sham group, ischemia-reperfusion group ( MCAO group) and isoflurance preconditioning group (ISO group). ISO group was exposed to isoflurane for 30 min and then underwent a 90 min middle cerebral arterial occlusion (MCAO), while MCAO group underwent MCAO only. At 24 h after reperfusion all the groups were investigated by modified neurological severity score for neurological deficits, TTC staining for infarct percentage. Cerebral cortices were harvested for HIF-1α, HO-1 and Bcl-2 protein expression level detection at 6 h, 24 h and 72 h after reperfusion using RT-PCR and western blot. Results The mNSS score and infarct percentage in ISO group decreased significantly compared with those of MCAO group at 24 h after reper-fusion(P < 0. 05). Compared with the MCAO group, ISO group had significantly up-regulated protein levels of HIF-1α, HO-1 and Bcl-2 at 6 h and 24 h after reperfusion(P < 0. 05). There was no difference between ISO group and MCAO group for 3 gene expression at 72 h(P > 0. 05). Conclusion Isoflurane preconditioning plays short-term cerebral protective effect through the up regulation of HIF-1α, HO-1 and Bcl-2 gene expression.

Objective:
To investigate the prevalence of depression and anxiety among transgender populations and the correlation with defense mechanism, so as to provide the evidence for improving mental health among transgender populations.
Methods:
Transgender populations that visited Psychosexual Outpatient Department of Beijing Huilongguan Hospital for the first time from December 2020 to December 2021 were enrolled. Participants' demographics, depression, anxiety and type of defense mechanisms were collected using self-designed questionnaires, Self-rating Depression Scale, Self-rating Anxiety Scale and Defense Style Questionnaire (DSQ). Factors affecting depression and anxiety were identified using a multivariable logistic regression model.
Results:
Totally 126 transgender individuals were enrolled, including 95 men (75.40%) with a mean age of (21.53±4.55) years and 31 women (24.60%) with a mean age of (23.58±5.55) years. The prevalence of depression was 46.83% among participants, including 44.07% of participants with mild depression, 30.51% with moderate depression and 25.42% with severe depression, and the prevalence of anxiety was 26.19% among participants, including 60.61% of participants with mild anxiety, 21.21% with moderate anxiety and 18.18% with severe anxiety. The detection of depression was 54.74% among men and 22.58% among women (P<0.05), and the detection of both depression (62.79% vs. 38.55%, P<0.05) and anxiety (41.86% vs. 18.07%, P<0.05) was significantly higher among transgender populations with self-injury or suicide behaviors than among those without. Multivariable logistic regression analysis showed that immature defense mechanisms increased the risk of depression (OR=1.034, 95%CI: 1.018-1.051) and anxiety (OR=1.031, 95%CI: 1.014-1.049) among transgender populations, while mature defense mechanisms reduced the risk of depression (OR=0.887, 95%CI: 0.832-0.946) and anxiety (OR=0.878, 95%CI: 0.821-0.938) among transgender populations.
Conclusions
The prevalence of depression and anxiety was 46.83% and 26.19% among transgender populations included in this study. Mature defense mechanisms are beneficial to reduce the risk of depression and anxiety among transgender populations.
Key words: transgender population depression anxiety defense mechanism
