Objective: To explore the association between health related behaviors and anxiety, depressive symptoms, and their co-occurrence among junior and senior high school students, so as to provide evidence for developing targeted mental health promotion strategies. Methods: From September to December 2023, a stratified cluster random sampling method was used to select 6 150 junior and senior high school students from 8 districts (counties) in a northwest region of China. The Generalized Anxiety Disorder-7 and Center for Epidemiologic Studies Depression Scale were used to assess anxiety and depressive symptoms, and their co-occurrence. Latent class analysis was used to identify latent classes of health related behaviors among junior and senior high school students, and Logistic regression models were used to analyze the association of the latent category of health related behaviors with anxiety and depressive symptoms, and their co-occurrence. Results: The detection rates of anxiety and depressive symptoms, and their co-occurrence were 8.0%, 22.0%, and 7.3%, respectively, among junior high school students, and 8.3%, 26.6%, and 7.6%, respectively, among senior high school students. Latent classes of health related behaviors were classified into four classes:the comprehensive high risk behavior group (586 students, 9.5%), the Internet addiction group (376 students, 6.1%), the insufficient sleep group (1 151 students, 18.7%), and the low risk behavior group (4 037 students, 65.6%). After controlling for confounding factors such as gender, ethnicity, and monitoring sites, Logistic regression model analysis showed that, compared with the low risk behavior group, the comprehensive high risk behavior group had elevated risks of anxiety and depressive symptoms, and their co-occurrence (junior high school students: OR =3.81, 5.52, 3.88; senior high school students: OR =4.57, 4.12, 5.43; all P <0.05). The Internet addiction group had elevated risks of anxiety and depressive symptoms, and their co-occurrence among junior high school students ( OR =1.89, 2.81, 1.89), and an elevated risk of depressive symptoms among senior high school students ( OR =2.41) (all P <0.05). The insufficient sleep group had an elevated risk of their co-occurrence among junior high school students ( OR =1.47), and elevated risks of anxiety and their co-occurrence among senior high school students ( OR =1.71, 1.99) (all P <0.05). Conclusion Latent classes of health related behaviors among junior and senior high school students are associated with anxiety and depressive symptoms, and their co-occurrence, as well as differences across school stages.

Objective:To investigate the effect of curcumin on phosphatidylinositol-3-kinase/protein kinase B/mammalian target of rapamycin (PI3K/Akt/mTOR) pathway on the autophagy of Bacille Calmette-Guérin (BCG)-infected macrophages.Methods:The infection model was established by infecting THP-1-derived macrophages with BCG. Five groups were involved in this study, which were control group, BCG group, BCG+ curcumin group, BCG+ curcumin+ IGF-1(PI3K agonist) group, and BCG+ curcumin+ LY294002 (PI3K inhibitor) group. The fluorescence intensity of autophagosomes was observed under fluorescence microscope using the fluorescent dye monodansylcadaverine (MDC staining). The expression of PI3K, Akt, mTOR, phospho-PI3K (p-PI3K), phospho-Akt (p-Akt), phospho-mTOR (p-mTOR), microtubule-associated protein 1 light chain 3-Ⅱ (LC3-Ⅱ), and Beclin-1 at protein level were detected by Western blot. Colony forming unit was used to detect macrophage load. Multiple independent, normal, and homogeneous data were compared using one-way analysis of variance, and pairwise comparisons were conducted using LSD test.Results:BCG infection significantly decreased the fluorescence intensity of autophagosomes, and the expression of autophagy marker proteins LC3-Ⅱ and Beclin-1 ( P<0.05), but increased the expression of p-PI3K, p-Akt, and p-mTOR ( P<0.05). Curcumin increased the fluorescence intensity of autophagosomes and enhanced the expression of LC3-Ⅱ and Beclin-1 proteins in a concentration-dependent manner ( P<0.05). Besides, curcumin inhibited the expression of p-PI3K, p-Akt, and p-mTOR ( P<0.05). The PI3K agonist IGF-1 reversed the above effects of curcumin. Compared with the BCG+ curcumin group, the fluorescence intensity of autophagosomes and the expression of LC3-Ⅱ and Beclin-1 proteins were further increased ( P<0.05), while the expression of p-PI3K, p-Akt and p-mTOR was further decreased ( P<0.05) in the BCG+ curcumin+ LY294002 group. Compared with the BCG group, the bacterial loads in the BCG+ curcumin group and the BCG+ curcumin+ LY294002 group decreased significantly ( P<0.05), while the bacterial load in the BCG+ curcumin+ IGF-1 group increased significantly ( P<0.05). Conclusions:Curcumin can promote the autophagy of BCG-infected macrophages, which contributes to the clearance of Mycobacterium tuberculosis by macrophages. Part of the mechanism may be related to the inhibition of PI3K/Akt/mTOR pathway.

Objective:To explore the clinical value of multi-parameter combined monitoring in guiding low-molecular-weight heparin (LMWH) therapy for intensive care unit (ICU) patients.Methods:A retrospective case-control study was conducted. A total of 381 patients who received LMWH therapy with anti-Ⅹa activity monitoring in the ICU of West China Hospital, Sichuan University between January 31st, 2022, and November 30th, 2023, were enrolled in this study. The cohort comprised 264 males and 117 females, with the age of 58 (48, 71) years old. Clinical data and relevant laboratory parameters were collected, including anti-Ⅹa activity, antithrombin activity (AT), thrombin-antithrombin complex (TAT), plasmin-antiplasmin complex (PIC), conventional coagulation parameters such as activated partial thromboplastin time (APTT), and indicators of hepatic/renal impairment such as alanine aminotransferase (ALT) and creatinine( CREA). Patients were stratified into three groups based on thrombotic event: thrombosis-controlled, progressive thrombosis, and bleeding group. Single-factor and adjusted multifactorial Logistic regression analysis were used to identify independent predictors of anti-xa activity levels.Results:Among 381 patients, thrombosis was controlled in 213 (55.9%) patients, progressed in 81 (21.3%) patients , and bleeding events occurred in 87 (22.8%) patients. The patients whose anti-Ⅹa activity levels lay entirely within the target range(0.2-0.4 IU/ml): Only 35 (16.4%) cases in the thrombosis-controlled group, 16 (19.7%) cases in the progressive thrombosis group, and 16 (18.4%) in the bleeding group. No significant differences in anti-Ⅹ a levels activity among the three groups ( H=1.678, P=0.432). Both single-factor and adjusted multifactorial Logistic regression identified low AT activity as an independent risk factor for failure to achieve target anti-Ⅹ a activity levels (AT nadir, OR=1.031,95% CI 1.016-1.046, P<0.05). Compared with the progressive thrombosis and bleedinggroup, the thrombosis-controlled group exhibited significantly higher proportion of TAT values below the cut-off value ( H=8.519, P=0.014), and a higher proportion of TAT/PIC ratios below the cut-off ( H=15.56, P<0.001). Patients with bleeding demonstrated significantly lower AT activity ( H=14.968, P=0.001), prolonged APTT ( H=6.815, P=0.033), higher ALT ( H=13.774, P=0.001), and higher CREA ( H=14.068, P=0.001) compared with the thrombosis-controlled or progressive thrombosis group. Conclusion:Laboratory monitoring is required for low-molecular-weight heparin (LMWH) therapy in ICU patients. While anti-Ⅹa activity reflects the anticoagulant effect of LMWH, the utility of anti-Ⅹ a activity for predicting thrombotic or hemorrhagic risks in LMWH treated ICU patients is limited. Reductions in TAT levels and TAT/PIC ratios are associated with a lower risk of thrombotic progression. Furthermore, abnormalities in conventional coagulation tests and standard hepatic/renal function parameters occur more frequently in patients experiencing hemorrhagic events.

Objective:To investigate the current status and influencing factors of barriers to going out among elderly patients with chronic obstructive pulmonary disease (COPD), and to provide a reference for implementing targeted preventive measures.Methods:Elderly COPD patients from the People's Hospital of Xinjiang Uygur Autonomous Region were selected between January and May 2024 by convenience sampling. A cross-sectional survey was conducted using a general information questionnaire, Scale on Barriers to Going Out for the Elderly, Perceived Isolation Scale and COPD Assessment Test (CAT).Results:A total of 270 questionnaires were distributed, with 250 valid responses, the effective response rate was 92.6%. Among the 250 elderly COPD patients, there were 124 males and 126 females, with age distributions: 116 patients aged 60-69 years, 94 aged 70-79 years, and 40 aged ≥80 years. The total score for Scale on Barriers to Going Out for the Elderly was (20.01 ± 4.09). The score on barriers to going out in elderly COPD patients were positively correlated with the Perceived Isolation Scale and CAT scores ( r = 0.456 and 0.625, both P <0.05). Multiple linear regression analysis revealed that age, oxygen therapy, exercise habits,Perceived Isolation Scale, and CAT score classification were the main influencing factors for barriers to going out ( t values were -2.85 to 8.93, all P<0.05), explaining 63.0% of the total variance. Conclusions:The level of barriers to going out in elderly COPD patients is moderate-to-high level. Healthcare professionals should emphasize the assessment of barriers to going out, closely monitor high-risk groups, and develop and implement interventions to prevent such barriers.

Objective To explore the value of MRI quantitative parameters and free/total prostate-specific antigen ratio(f/tPSA)for diagnosing prostate imaging reporting and data system(PI-RADS)3-point clinically significant prostate cancer(csPCa).Methods Totally 57 patients with PI-RADS 3-point prostate lesions were retrospectively enrolled,including 18 prostate cancer(PCa)(PCa group)and 39 benign hyperplasia with chronic prostatitis(non-PCa group).The former included 12 cases of csPCa and 6 cases of clinically insignificant PCa(ciPCa).Taken non-PCa and ciPCa into non-csPCa group(n=45),laboratory and MRI parameters(apparent diffusion coefficient[ADC],T1,T2,proton density[PD]values)were compared between PCa and non-PCa groups,also between csPCa and non-csPCa groups.Based on laboratory and MRI parameters being statistically different between groups according to univariate analysis,combined models were established using logistic regression.The efficacy of laboratory,MRI parameters and combined models for differentiating PCa and non-PCa as well as csPCa and non-csPCa were evaluated.Results ADC,T1,T2,PD values in PCa group were all lower those in non-PCa group(all P＜0.05),and f/tPSA,ADC,T1,T2 and PD values in csPCa group were all lower than those in non-csPCa group(all P＜0.05).AUC of ADC,T1,T2 and PD values for differentiating PCa from non-PCa was 0.662,0.755,0.793 and 0.729 respectively,while of ADC-T1-T2-PD combined model was 0.839,higher than that of ADC alone(P＜0.05)but not significantly different with T1,T2 and PD values alone(all P＞0.05).AUC of f/tPSA,ADC,T1,T2 and PD values for differentiating csPCa from non-csPCa was 0.692,0.759,0.741,0.805 and 0.737,respectively,while of ADC-T1-T2-PD combined model was 0.889,higher than that of f/tPSA,ADC and T1 values alone(all P＜0.05)but not significantly different with that of T2 and PD value alone(both P＞0.05).AUC of f/tPSA-ADC-T1-T2-PD combined model was 0.898,higher than that of f/tPSA,ADC,T1 and PD values alone(all P＜0.05)but not significantly different with T2 value and ADC-T1-T2-PD combined model(both P＞0.05).Conclusion MRI quantitative parameters combined with f/tPSA could effectively diagnose PI-RADS 3-point csPCa.

OBJECTIVE To evaluate the long-term cost-effectiveness of insulin degludec and insulin aspart （IDegAsp） in patients with type 2 diabetes mellitus （T2DM） in China. METHODS A cost-effectiveness analysis was conducted from the perspective of the Chinese healthcare system， using the CORE diabetes model to simulate long-term （20-year） health and economic outcomes. Baseline cohort characteristics and treatment effect data were derived from the CREATE study. The prices of glucose- lowering drugs were obtained from medical insurance payment standards and the average winning bid prices in the follow-up round of the specialized centralized procurement for insulin， while the daily dosages were derived from the CREATE study. The costs of complications and utility values were obtained from published literature， with a discount rate of 5%. One-way sensitivity analysis， scenario analysis， and probabilistic sensitivity analysis were performed to verify the robustness of the results. RESULTS Patients switching from previous once-daily basal insulin regimens to IDegAsp therapy gained an incremental 0.190 quality-adjusted life year （QALY） with direct medical cost savings of 42 163.58 yuan. For those switching from premixed insulin therapies， IDegAsp treatment provided 0.130 incremental QALY and reduced direct healthcare costs by 41 129.11 yuan. The outcome was significantly influenced by the discount rate and the cost of complications. Probabilistic sensitivity analysis and scenario analysis confirmed the robustness of these findings. CONCLUSIONS Switching from previous daily basal insulin or premixed insulin regimens to IDegAsp in Chinese patients with T2DM can improve patients’ long-term health outcomes and achieve cost savings， making it a more cost-effective treatment option.

OBJECTIVE To systematically evaluate the efficacy and safety of Insulin degludec and liraglutide injection （IDegLira） and Insulin glargine and lixisenatide injection（iGlarLixi） in the treatment of type 2 diabetes mellitus（T2DM）， and provide an evidence-based basis for the clinical treatment of T2DM. METHODS Computerized searches of PubMed， Embase， the Cochrane Library， CNKI， Wanfang data and VIP were conducted with a time frame from the inception to August 2024. Randomized controlled trials（RCTs） were rigorously screened according to inclusion and exclusion criteria， from which information was extracted and included studies were evaluated for risk of bias. Network meta-analysis was performed using Stata 14.0 software. RESULTS A total of 15 RCTs， including 9 513 patients， were included， involving four treatment regimens： IDegLira， iGlarLixi， insulin degludec（IDeg）， and insulin glargine（iGlar）. The differences between IDegLira and iGlarLixi were not statistically significant（P＞0.05） for the outcome indexes of glycosylated hemoglobin（HbA1c）， fasting blood glucose， body weight， and the incidence of adverse events（P＞0.05）； for the outcome index of the incidence of hypoglycemic events， IDegLira was significantly superior to iGlarLixi [OR＝0.41，95%CI（0.18，0.91），P＜0.05]. Surface under the cumulative ranking curve（SUCRA） results showed that iGlarLixi（84.5%）＞IDegLira（81.7%） in lowering HbA1c； IDegLira（71.3%）＞iGlarLixi（20.0%） in lowering fasting blood glucose； IDegLira（90.7%）＞iGlarLixi（61.8%） in lowering body weight； IDegLira（95.5%）＞iGlarLixi（9.7%） in reducing the incidence of hypoglycemic events； and IDegLira（27.1%）＞iGlarLixi（14.5%） in reducing the incidence of adverse events. CONCLUSIONS iGlarLixi has better therapeutic efficacy in reducing HbA1c； IDegLira has better therapeutic efficacy in reducing fasting blood glucose and body weight. IDegLira has the lowest risk of hypoglycemia.
