Objective:To examine the relationship between internalized homophobia and self-concept clarity in lesbians,and explore the mediating role of gender role conflict and the moderating role of loneliness.Methods:Totally 510 lesbians were selected and assessed with the Internalized Homophobia Scale(IHS),Gender Role Con-flict Scale-Short Form(GRCS-SF),Self-Concept Clarity Scale(SCCS),and UCLA Loneliness Scale(UCLALS).Model 4 in the PROCESS macro program was used to test the mediating role of gender roles,and Model 14 was used to test the moderating role of loneliness.Results:The IHS scores were negatively correlated with the SCCS scores(r=-0.11,P＜0.05).Gender role conflict fully mediated the relationship between lesbian internalized ho-mophobia and self-concept clarity(indirect effect=-0.09,95％CI=-0.13--0.05).Loneliness moderated the relationship between gender role conflict and self-concept clarity among lesbians(Bsimple=-0.17,-0.30,P＜0.01).Conclusion:It suggests that the internalized homophobia may be related to self-concept clarity in lesbi-ans,with gender role conflict as a mediator and loneliness as a moderator moderates between their relationships.

Objective To explore the role of transcription factor EB(TFEB)induced by aerobic exer-cise in improving insulin resistance(IR)of skeletal muscles in high-fat diet mice.Method Eighteen male SPF C57BL/6 mice aged 6 weeks were randomly divided into a common diet group(CON),a high-fat diet group(HFD),and a high-fat diet exercise group(HFDE),each of 6.Both high-fat groups were on high-fat diet for 12 weeks.Then the HFDE group underwent daily 60-minute tread-mill exercise with the slope of 0°,at a speed of 12 m/min,5 times per week for 12 weeks.Finally,the glucose tolerance and insulin sensitivity were detected using the intraperitoneal injection glucose tol-erance test(IPGTT)and intraperitoneal injection insulin tolerance test(IPITT).The fasting blood glu-cose and insulin contents were measured by biochemical method,and the IR level was calculated by using the homeostatic model assessment of insulin resistance(HOMA-IR).Moreover,Western blotting was employed to detect the expression of phosphorylated transcription factor EB(pTFEB)and TFEB in skeletal muscle,glucose transporter 4(GLUT4)in cytoplasm and membrane,phosphorylated insulin re-ceptor substrates1(pIRS1),phosphorylated protein kinase B(pAKT),phosphoinositide 3-kinase(PI3K),and phosphorylated akt substrate of 160 kD(pTBC1D4)in skeletal muscle.The correlation of pTFEB and TFEB to insulin signaling pathway-related proteins was analyzed.Results(1)Compared with the CON group,there was a significant increase in the average body weight,IPGTT,blood glucose at each time point of IPGTT,area under curve(AUC),serum insulin,HOMA-IR,protein expressions of pTFEB,total-TFEB and GLUT4 in cytoplasm of the HFD group(P<0.01),but a significant decrease in the average protein expressions of pIRS1,pAKT,PI3K,pTBC1D4 and GLUT4 in cell membrane of skeletal muscles(P<0.01).However,no significant differences were found between the two groups in the average expression of pTFEB and T-TFEB proteins.(2)Compared to the HFD group,a signifi-cant increase was found in the average body weight,blood glucose at each time point of IPGTT,blood glucose of IPITT at 0 min,30 min and 60 min and AUC,serum insulin,HOMA-IR,expres-sions of pTFEB,T-TFEB and GLUT4 in cytoplasm of HFDE group(P<0.05 or P<0.01),with a signifi-cant decrease in the average protein expressions of pIRS1,pAKT,PI3K,pTBC1D4 and GLUT4 in cell membrane and T-TFEB in nucleus(P<0.01).(3)TFEB was negatively correlated with the expres-sion of pIRS1,PI3K,pAKT,and pTBC1D4 proteins(r=-0.8642,r=-0.7789,r=-0.8946,r=-0.8040)but positively correlated with cytoplasmic GLUT4(r=0.8532,P<0.01).Moreover,TFEB in the nucleus was of positive correlation with GLUT4 in the cell membrane(r=0.7744,P<0.01).Conclusions High-fat diet can decrease the expression of insulin signaling pathway related proteins in skeletal mus-cles of mice and weaken their insulin action,leading to the disorder of glucose and lipid metabolism.However,aerobic exercise can significantly increase the expression of such proteins to promote insulin function and sensitivity,and relieve disorders in glucose and lipid metabolism.This effect may be achieved through the promotion of skeletal muscle TFEB nuclear translocation,which activates IRS1/PI3K/AKT/TBC1D4/GLUT4 signaling pathway and facilitates GLUT4 membrane translocation,ultimately enhancing glucose uptake in skeletal muscle cells.The authors speculate that the TFEB-mediated insu-lin signaling pathway may be an important molecular pathway for aerobic exercise to improve insulin re-sistance.

Objective:Analysis of the characteristics of influenza epidemic in Anhui Province and quantification of the impact of different factors on influenza occurrence, providing scientific basis for better influenza prevention and control.Methods:Descriptive analysis and factor analysis were conducted on influenza-like illness (ILI) cases and RT-PCR results in Anhui Province from 2013 to 2021 using data from China's Influenza Monitoring Information System.Results:The percentage of influenza-like illness (ILI%) of sentinel hospitals in Anhui Province from April 1, 2013 to March 31, 2021 was 3.80% (1 209 142/31 779 987), showing an overall increasing trend, with a relatively high proportion in 2017-2018 at 4.30% (191 148/4 448 211). The proportion of ILI cases in infants and young children aged 0-4 years was a relatively high at 54.14% (654 676/1 209 142), and the highest ILI% was observed in Fuyang City, Anhui Province (6.25%, 236 863/3 788 863). Laboratory monitoring results showed that the positive rate of ILI cases in sentinel hospitals in 8 influenza monitoring years was 16.38% (34 868/212 912), showing an increasing trend year by year, with a relatively proportion in 2017-2018 at 26.19% (6 936/26 488). The detection rate of school-age children aged 5-14 years was a relativelyhigh at 28.81% (13 869/48 144), and the positive rate was a relatively high in Wuhu City among the 16 cities, reaching 22.01% (2 693/122 237). Influenza activity showed a single peak in winter-spring and alternating double peaks in winter-spring and summer, with different subtypes alternating, and A (H3N2) was the dominant subtype in summer. The results of a multiple logistic regression model showed that the positive rate was higher in 2017-2018, among children aged 5-14 years, in winter, and in southern Anhui.Conclusions:Influenza epidemic in Anhui Province has a clear seasonal pattern, and the ILI% and detection rate have shown an upward trend from 2013 to 2021. Therefore, it is suggested to ensure vaccine supply before the winter-spring influenza season arrives, and to strengthen vaccine uptake and health education to avoid the risk of infection during the peak period of influenza.

Objective To investigate the efficacy and safety of lenvatinib in patients with unresectable hepatocellular carcinoma (HCC) previously treated with tyrosine kinase inhibitor (TKI). Methods A retrospective analysis was performed for the clinical data of 76 patients with unresectable HCC who were treated with lenvatinib in Beijing Ditan Hospital, Capital Medical University, from January 2019 to January 2020, and according to the treatment method, they were divided into TKI previously untreated group with 49 patients and TKI treatment-experienced group with 27 patients. The patients were observed till one year after enrollment, adjustment of treatment regimen, tumor progression, or death. The two groups were compared in terms of progression-free survival (PFS) time, objective response rate (ORR), disease control rate (DCR), and incidence rate of adverse events. The t -test or the Wilcoxon rank-sum test was used for comparison of continuous data between two groups, and the chi-square test or the Wilcoxon rank-sum test was used for comparison of categorical data between two groups; the Kaplan-Meier method was used for survival analysis, and the log-rank test was used for comparison between groups. Results There were no significant differences between the TKI previously untreated group and the TKI treatment-experienced group in median PFS time (115 days vs 72 days, P =0.148), ORR (36.7% vs 18.5%, P =0.098), DCR (65.3% vs 55.6%, P =0.402), and incidence rates of grade ≥3 adverse events (24.5% vs 18.5%, P =0.550). Conclusion Patients with unresectable HCC previously treated with TKI can benefit from lenvatinib and have good safety, with similar results to those treated with TKI for the first time.

Dendritic cell-based cancer vaccines (DC vaccines) have been proved efficient and safe in immunotherapy of various cancers, including melanoma, ovarian and prostate cancer. However, the clinical responses were not always satisfied. Here we proposed a novel strategy to prepare DC vaccines. In the present study, a fusion protein SNU containing a secretin-penetratin (SecPen) peptide, NY-ESO-1 and ubiquitin was designed and expressed. To establish the DC vaccine (DC-SNU), the mouse bone marrow-derived DCs (BMDCs) were isolated, pulsed with SNU and maturated with cytokine cocktail. Then peripheral blood mononuclear cells (PBMCs) from C57BL/6 mice inoculated intraperitoneally with DC-SNU were separated and cocultured with MC38/MC38
