The innate immune sensor NLRP3 inflammasome overactivation is involved in the pathogenesis of ulcerative colitis. PGAM5 is a mitochondrial phosphatase involved in NLRP3 inflammasome activation in macrophages. However, the role of PGAM5 in ulcerative colitis and the mechanisms underlying PGAM5 regulating NLRP3 activity remain unknown. Here, we show that PGAM5 deficiency ameliorates dextran sodium sulfate (DSS)-induced colitis in mice via suppressing NLRP3 inflammasome activation. By combining APEX2-based proximity labeling focused on PGAM5 with quantitative proteomics, we identify NEK7 as the new binding partner of PGAM5 to promote NLRP3 inflammasome assembly and activation in a PGAM5 phosphatase activity-independent manner upon inflammasome induction. Interfering with PGAM5-NEK7 interaction by punicalagin inhibits the activation of the NLRP3 inflammasome in macrophages and ameliorates DSS-induced colitis in mice. Altogether, our data demonstrate the PGAM5-NEK7 interaction in macrophages for NLRP3 inflammasome activation and further provide a promising therapeutic strategy for ulcerative colitis by blocking the PGAM5-NEK7 interaction.

Objective To understand the influencing factors of chronic dyslipidemia in T2DM patients who signed a contract for diabetes point system management in Qingpu District, and to provide a basis for comprehensive intervention and prevention and control of dyslipidemia in T2DM patients and to optimize the management strategy of Qingpu District diabetes point system. Methods Among the T2DM patients who signed the diabetes point system from 2017 to 2023, patients with chronic dyslipidemia and normal blood lipids were selected and included in the case group and the control group, respectively. A case-control study was conducted with 1:1 matching by age and gender to analyze the factors influencing dyslipidemia. Results Multifactorial paired logistic regression analysis showed that overweight/obesity and central obesity and smoking in T2DM patients increased the risk of dyslipidemia by 1.93, 2.27, and 2.16 times, respectively. Long-term use of lipid-lowering drugs, duration of diabetes for 5 years or more, regular physical exercise, knowledge of blood lipid status, and married status could reduce the risk of dyslipidemia in T2DM patients (OR values were 0.547, 0.452, 0.685, 0.386 and 0.354, respectively). Current complications (history of stroke, coronary heart disease, and renal insufficiency) were also associated with dyslipidemia (OR=1.802, 95% CI:1.125-2.888). Conclusion The management of diabetes point system in Qingpu District should strengthen the feedback and interpretation of blood lipid monitoring results, improve patients’ health awareness of blood lipid management, and actively take comprehensive management of lifestyle intervention and drug treatment to effectively control blood lipid and reduce the occurrence of related complications.

Objective:To develop a Problematic Short Video Use Scale(PSVUS)and evaluate its validity and reliability.Methods:Through literature review and interviews,and with reference to the Diagnostic and Statisti-cal Manual of Mental Disorders,Fifth Edition(DSM-5)diagnostic guidelines for internet gaming disorder,the items were compiled.Initially,979 individuals(aged 14-74 years)participated in the survey,and 362 of them were re-tested after two weeks.The Perceived Stress Scale(PSS-4),UCLA Loneliness Scale(ULS-8),Brief Self-Control Scale(BSCS),and Hospital Anxiety and Depression Scale(HADS)were used to test the criterion-related validi-ty.Multiple classification methods were used to determine the cut-off value.Additionally,a 9-item brief version of the scale(PSVUS-9)was developed.Results:The PSVUS consists of 27 items organized into 9 dimensions(preoc-cupation,with drawal,tolerance,unsuccessful attempts,escape,continuation despite harm,deception,loss of inter-est,and functional impairment),explaining 78.71％of the total variance,with item factor loadings ranging from 0.62 to 0.95.The nine-factor structure exhibited good fit(x2/df=2.00,CFI=0.97,RMSEA=0.05).The scores of the dimensions were correlated with the scores of the PSS-4,ULS-8,BSCS and HADS(ICC=|0.21|-|0.68|,Ps＜0.05).The Cronbach's α coefficient of the PSVUS was 0.95,and the test-retest reliability was 0.83.The cut-off score for problematic use was determineded to be 70 or above.The PSVUS-9 score was correlated with the scores of the criterion measures(ICC=|0.39|-|0.68|,Ps＜0.01).The Cronbach's α coefficient of PSVUS-9 was 0.86 and the test-retest reliability was 0.80.A score of 24 or higher on the PSVUS-9 was indicative of problematic use.Conclusion:The Problematic Short Video Use Scale(PSVUS)and its brief version demonstrate good validity and reliability,and could be used to measure and screen for problematic short video use.

Objective To investigate the current status of frailty in patients on maintenance hemodialysis(MHD),and explore the correlation of frailty with anxiety and depression.Methods General information,clinical data and blood biochemical data of 101 cases who underwent MHD in Department of Nephrology,Shunde Hospital Affiliated to Jinan University from January 2023 to January 2024 were collected.FRAIL scale was applied to evaluate the frailty of the patients,and they were accordingly classified into frailty group and non-frailty group(including pre-frail and non-frail participants).Anxiety and depression were evaluated by GAD-7 and PHQ-9 scale.Univariate analysis and logistic regression were used to explore the association of frailty with anxiety,depression and other possible influencing factors.Results Among the 101 cases,29 cases(28.71%)were includedin frailty group and 72 cases(71.29%)in non-frailty group.There were 42 patients with depression(41.58%)and 25 with anxiety(24.75%).In the frailty group,the prevalence of depression was 65.52%and that of anxiety 55.17%.There were significant differences in age,grip strength,exercise,stroke and coronary heart disease,anxiety and depression,ferritin and CRP between the two groups(P＜0.01).Multivariate regression analysis showed that depression,anxi-ety,no exercise,stroke and high ferritin concentration were independent risk factors for frailty in MHD patients(P＜0.05).Conclusion In patients on MHD,frailty is closely associated with depression,anxiety,and lack of exercise,and stroke as well as high ferritin concentration are independent risk factors for frailty.

Objective:To describe disability rates of dementia in community residents aged 65 years and over in China,and explore related risk factors of disability.Methods:This study conducted an in-depth data analysis of the China Mental Health Survey.World Health Organization Disability Assessment Schedule 2.0(WHODAS 2.0)was used to assess dementia disability,Community Screening Interview for Dementia(CSID)and Geriatric Mental Status Examination(GMS)were used for dementia screening and diagnosing.Univariate analysis was used to calcu-late the weighted disability rates of dementia in population and in patients,and their population distribution.Multiple linear regression and logistic regression were used to analyze the risk factors of the occurrence of dementia disability and its severity.Results:The weighted disability rate of dementia was 2.1％in population,and 38.6％in pa-tients.The disability rates of comorbid dementia in population and in patients were higher than those of patients with only dementia.Female,older age,lower education level,lower economic status,and lower cognitive test scores in CSID had higher disability rates of dementia in population.Female and urban resident had higher disability rates of dementia in patients.Multiple linear regression showed economic status(β=0.11),gender(β=0.11),age(β=0.10),and treatment in the last 12 months(β=-0.20)were statistically associated with WHODAS 2.0 scores.Multiple logistic regression showed female(OR=2.81)and treatment in the last 12 months(OR=2.38)were statistically associated with disability.Conclusions:Persons with low economic status,female and elderly peo-ple are the high-risk groups for dementia disability.It should be paid attention to prevent dementia and its conse-quential disabilities.

Objective: To analyze the longitudinal association between mobile phone dependence and depressive symptoms in college students, so as to provide a theoretical basis for psychological health education among college students. Methods: From November 2021 to June 2023, 2 515 first year students from 2 universities in Yunnan Province were surveyed with a questionnaire by a cluster random sampling method, including baseline survey (November 2021, T1) and three follow up visits (June 2022, T2; November 2022, T3; June 2023, T4). The Self rating Questionnaire for Adolescent Problematic Mobile Phone Use and the Depression Anxiety Stress Scales-21 (DASS-21) were used to evaluate mobile phone dependence and depressive symptoms of college students. The χ 2 test was used to analyze the difference in depressive symptoms among different demographic groups, and a generalized estimation equation model was established to analyze the association between mobile phone dependence symptoms and depressive symptoms. Results: The detection rates of depressive symptoms among university students in Yunnan Province at time points T1, T2, T3, and T4 were 23.02%, 33.36%, 34.79% and 35.51%, respectively. There were statistically significant differences in the detection rates of depressive symptoms among college students with different sacademic burden (T1, T2, T3, T4), different number of close friends (T1, T2, T3), as well as their father s educational level (T1), mothers educational level (T2, T4), gender (T4), major (T3, T4), education (T2, T3, T4), family residency (T1, T2), and family economic conditions (T1, T2, T4) ( χ 2= 59.68 , 49.38, 16.70, 39.31; 55.35, 26.01, 16.69; 10.22; 14.87, 11.51; 14.90; 27.81, 50.28; 9.75, 7.42, 24.76; 6.06, 4.47 ; 15.88, 14.58, 15.85, P < 0.05 ). After controlling for demographic variables and confounding factors in the generalized estimation equation model, mobile phone dependence ( β =0.11), withdrawal symptoms of mobile phone dependence ( β =0.14), and the physical and mental effects of mobile phone dependence ( β =0.14) were all positively correlated with depressive symptoms ( P <0.01). Further gender analysis showed that depressive symptoms in both boys ( β =0.13, 0.13, 0.18) and girls ( β =0.10, 0.13, 0.13 ) were associated with mobile phone dependence, withdrawal symptoms of mobile phone dependence and the physical and mental effects of mobile phone dependence ( P <0.01). Conclusions Depressive symptoms of college students are positively correlated with mobile phone dependence, and family economic conditions, academic burden and number of close friends are factors that continued to affect depressive symptoms. College students should be guided to pay attention to the impact of excessive use of mobile phones on their physical and mental health, use mobile phones reasonably to reduce the incidence of depressive symptoms among college students.

Objective: To explore the relationship between processed food consumption and blood pressure level of students in a university in Yunnan Province, so as to provide the reference for preventing hypertension in university students. Methods: In October 2021, a cluster sampling method was used to select 4 781 freshmen from a university in Kunming, Yunnan Province. The frequency of processed food consumption of university students was assessed by using the dietary frequency questionnaire, and height, weight and blood pressure were measured. Mann-Whitney test and Kruskal-Wallis test were used to compare the differences in blood pressure level of university students with different demographic variables, and the association between processed food consumption and blood pressure level was analyzed with a generalized linear model. Results: Among the students of a university in Yunnan Province, the detection rates of systolic prehypertension and hypertension were 33.86% and 1.23%, and the detection rates of diastolic prehypertension were 32.13% and hypertension 7.22%. The results of generalized linear model analysis showed that after controlling for demographic variables and other variables that might affect the blood pressure level of university students, the consumption of processed food (bread and cake: β =0.15, 95% CI =0.01-0.29) and ultra processed food (coffee beverage: β =-0.29, 95% CI =-0.54--0.03) were associated with systolic blood pressure level( P <0.05). The consumption of processed food (salted duck egg: β =0.21, 95% CI =0.01-0.41) was correlated with the diastolic blood pressure of college students ( P <0.05). Conclusions Processed food consumption in university students may increase the risk of high blood pressure.The education of healthy eating among college students should be strengthened to reduce the consumption of processed foods.

Objective:To evaluate direct and indirect costs for schizophrenia,major depressive disorder(MDD)and bipolar disorder,and to compare their differences of cost composition,and to explore the drivers of the total costs.Methods:A total of 3 175 inpatients with schizophrenia,MDD,and bipolar disorder were recruited.In-patient's self-report total direct of medical costs outpatient and inpatient,out-of-pocket costs,and direct non-medical costs were regarded as direct costs.Productivity loss and other loss caused by damaging properties were defined as indirect costs.The perspectives of this study included individual and societal levels.Multivariate regression analysis was applied for detecting the factors influencing disease costs.Results:The total cost of schizophrenia was higher than those of MDD and bipolar disorder at individual and societal levels.The indirect costs of three mental disorders were higher than the direct costs,and the indirect cost ratio of bipolar disorder was higher than those of schizophre-nia and MDD.Age,gender,working condition and marital status(P＜0.05)were the important drivers of total costs.Conclusion:The economic burden of the three mental disorders is relatively heavy.Schizophrenia has heaviest disease burden,and the productivity loss due to mental disorders is the driving force of the soaring disease cost

Objective:To explore the clinical characteristics and related socio-demographic factors of schizo-phrenia patients with different ages of onset.Methods:Totally 2 016 patients with schizophrenia aged 15 to 70 were selected according to the diagnostic criteria for schizophrenia in the Diagnostic and Statistical Manual of Mental Disorders,Fifth Edition.All of the patients were interviewed by psychiatrists using the Mini International Neuropsy-chiatric Interview to diagnose schizophrenia,Clinical-Rated Dimensions of Psychosis Symptom Severity(CRDPSS)and the Positive and Negative Syndrome Scale(PANSS)to assess symptoms.The cut-off points were 18 and 25 years old for three age groups,i.e.early onset(EOS),youth onset(YOS)and adult onset(AOS).Statistical analy-ses were performed by analysis of variance Pearson correlation analysis,and multivariate linear regression.Results:The early-onset patients had the highest total PANSS score(73.8±28.0)and CRDPSS score(11.7±5.4).Fe-male gender,high education level,Han ethnicity,early onset age,and slower onset of illness were negatively corre-lated with the total and dimension score of PANSS scale and CRDPSS scale(standardized regression coefficient:0.04-0.47),and income level and smoking were negatively correlated with those score(standardized regression coefficient:-0.04--0.14).Conclusion:Early-onset schizophrenia patients have more severe symptoms,and fe-male,high education level,early-onset disease,and chronic onset are the risk factors of symptom severity in patients with schizophrenia.
