BackgroundLow medication compliance among patients with severe mental disorders increases the disease burden on both the patients' families and the society. Medication adherence is influenced by numerous factors. Traditional methods such as Logistic regression struggle to quantify the importance of these factors. By introducing Extreme Gradient Boosting （XGBoost） combined with Shapley Additive Explanations （SHAP）， enables the quantification of the relative contribution weights of each factor， providing support for identifying the core influencing factors. ObjectiveTo explore the influencing factors of medication adherence among patients with severe mental disorders in Zhuhai， aiming to provide references for optimizing patient management strategies. MethodsExtract the data of patients with severe mental disorders who were registered on the mental health system platform in Zhuhai City from January 1， 2023 to March 31， 2025. A total of 9 329 patients were finally included for analysis. Influencing factors were screened using univariate analysis and multivariate logistic regression analysis， and an XGBoost model combined with the SHAP algorithm was constructed to quantify the importance of each influencing factor. ResultsAmong 9 329 patients， 8 446 demonstrated medication adherence， yielding an adherence rate of 90.53%. Multivariable analysis identified several risk factors significantly associated with medication non-adherence， being unmarried （OR=1.237， 95% CI： 1.019–1.502） or divorced （OR=1.389， 95% CI： 1.038–1.832）， a diagnosis of mental retardation with psychiatric disorders （OR=3.025， 95% CI： 2.402–3.796） or paranoid psychosis （OR=5.117， 95% CI： 3.086–8.299）， a disease duration of 2–4 years （OR=1.355， 95% CI： 1.085–1.696）， 4–6 years （OR=2.143， 95% CI： 1.671–2.747）， or >6 years （OR=1.681， 95% CI： 1.365–2.079）， lack of guardian subsidies （OR=1.412， 95% CI： 1.099–1.801）， absence of a disability certificate （OR=1.900， 95% CI： 1.588–2.282）， not being enrolled in care and support groups （OR=1.384， 95% CI： 1.183–1.617） or community services （OR=1.313， 95% CI： 1.042–1.645）， and not cohabiting with a guardian （OR=1.257， 95% CI： 1.048–1.501）. Conversely， the enrollment in special outpatient disease programs （OR=0.716， 95% CI： 0.609–0.842） and a family history of mental illness （OR=0.713， 95% CI： 0.503–0.982） were identified as protective factors. The XGBoost model exhibited robust predictive performance， with a sensitivity of 0.433， specificity of 0.944， accuracy of 0.891， Area Under the Curve （AUC） of 0.837， and F1 value of 0.449. Feature importance ranking indicated that the top three factors were disease duration， diagnosis， and the acquisition of disability certificates. ConclusionPolicy-based support （acquisition of disability certificates， special outpatient disease enrollment） and clinical disease characteristics （disease duration， diagnosis type） are key factors affecting medication adherence among patients with severe mental disorders in Zhuhai City. ［Funded by Zhuhai Medical Research Project （number， 2220009000281）］

ObjectiveTo investigate the effect of different exercise interventions on metabolism and liver parameters in patients with metabolic dysfunction-associated fatty liver disease （MAFLD）， and to provide evidence-based recommendations for clinical exercise rehabilitation. MethodsThis study was conducted according to the PRISMA guidelines， and the protocol was registered on the PROSPERO platform， with a registration number of CRD42025641717. PubMed， Web of Science， Scopus， Wiley Online Library， CNKI， Wanfang Data， and VIP were searched for related articles published up to September 2024. The Cochrane tool for assessing risk of bias was used to assess the quality of articles， and Stata MP 17.0 was used to perform the network meta-analysis. ResultsA total of 57 articles were included， involving 2 648 patients. The results showed that aerobic exercise combined with resistance exercise had the best effect in improving body mass index （mean difference ［WMD］=-0.97， 95% confidence interval ［CI］： -1.66 to -0.28］， P<0.05， surface under the cumulative ranking curve ［SUCRA］=85.4） and triglycerides （WMD=-29.6， 95%CI： -46.66 to 12.54， P<0.05， SUCRA=87.3）； resistance exercise was the optimal intervention method for improving total cholesterol （WMD=-15.99， 95%CI： -24.19 to -7.79， P<0.05， SUCRA=79.9） and glutamine transaminase （WMD=-8.08， 95%CI： -12.13 to -4.02， P<0.05， SUCRA=87.3）； low-intensity aerobic exercise had the best effect in improving aspartate aminotransferase （WMD=-4.3， 95%CI： -8.45 to -0.15， P<0.05， SUCRA=73.5）， gamma-glutamyl transpeptidase （GGT） （WMD=-3.26， 95%CI： -7.79 to 1.27， P>0.05， SUCRA=82.3）， and glycated hemoglobin （HbA1c） （WMD=-0.6， 95%CI： -2.02 to 0.82， P>0.05， SUCRA=78.8）； moderate-intensity aerobic exercise was the optimal intervention modality to improve Homeostasis Model Assessment of Insulin Resistance （WMD=-0.92， 95%CI： -1.51 to -0.33， P<0.05， SUCRA=69.4）. It should be noted that there were no significant differences in HbA1c and GGT across different exercise interventions （all P>0.05）， suggesting that there was currently no sufficient statistical evidence to support that exercise could improve these two indicators. ConclusionBased on the comprehensive league table and cumulative probability ranking， aerobic exercise combined with resistance exercise， resistance exercise， and low- and moderate-intensity aerobic exercise may be the best exercise modality for improving key indicators in MAFLD patients， and targeted exercise modalities should be selected for intervention against different indicators； however， due to limitations of the original studies， further studies are needed for validation and exploration.

Background Currently,there has been a gradual increase in the incidence of mental diseases,becoming a problem that has attracted great concern of the general public.Zhuhai is a core city of the Guangdong-Hong Kong-Macao Greater Bay Area,and the local government have attached great importance to the mental health of residents.The systematic study on the mental health has focused largely on pregnant women and medical workers,yet few are on the adult residents.Objective To investigate the prevalence and its influencing factors of anxiety and depression among adult residents in Zhuhai,so as to provide references for formulating targeted psychological intervention strategies.Methods From September 1 to December 1,2021,a cohort of 5 600 permanent residents aged 18 years and above in Zhuhai were selected through multistage sampling.All participants were subjected to complete Patients' Health Questionnaire Depression Scale-9 item(PHQ-9),Generalized Anxiety Disorder Scale-7 item(GAD-7)and National Mental Health Literacy Questionnaire based on Wenjuanxing software.Then Logistic regression was employed to identify the factors associated with anxiety and depression among the residents.Results Among the 5 600 residents,depressive symptoms were detected in 842(15.04％)residents and anxiety symptoms in 579(10.34％)residents.Logistic regression analysis yielded that female gender(OR=1.488),living in Doumen district(OR=1.942),junior college/undergraduate level(OR=3.602),postgraduate and above(OR=5.904),irregular meal pattern(OR=3.320),comorbid chronic diseases(OR=3.244),disqualification of self-assessment(OR=3.414)and disqualification of mental health skill(OR=2.131)were risk factors for depression symptoms,whereas age≥25 years old(of all age groups OR<1),monthly per capita income>20 000 yuan(OR=0.438)and exercising≥3 times a week(OR=0.431)were protective factors for depression symptoms.Age of 25～34 years old(OR=2.051),living in Jinwan district(OR=1.729)or Doumen district(OR=1.901),junior college/undergraduate level(OR=2.955),postgraduate and above(OR=6.662),irregular meal pattern(OR=2.741),comorbid chronic diseases(OR=3.535),disqualification of self-assessment(OR=3.325)and disqualification of mental health skill(OR=1.838)were risk factors for anxiety symptoms,while monthly per capita income of 6 001～9 000 yuan(OR=0.665)and exercising≥3 times a week(OR=0.572)were protective factors for anxiety symptoms.Conclusion The mental health status of adult residents in Zhuhai is affected by various factors,including gender,age,region of residence,education level,meal pattern,exercise frequency and chronic diseases.

Objective:To explore the advantages of the modified right renal artery dissection in the laparoscopic resection of right renal carcinoma combined with venous tumor thrombus.Methods:From January 2016 to June 2016, a retrospective analysis of the three-dimensional CT images of renal blood vessels in 70 patients with full abdominal CT plain scan plus enhanced scan from Shandong Provincial Hospital Affiliated to Shandong First Medical University was performed. On the sagittal plane of the right margin of the aorta, the right renal artery was detected to locate above the left renal vein in 14 cases (20.0%), posterior in 33 cases(47.1%), and below in 23 cases(32.9%). In addition, on the sagittal plane of the left margin of the inferior vena cava, the right renal artery was detected to locate above the left renal vein in 1 case (1.4%), posterior in 26 cases(37.1%), and below in 43 cases (61.4%). Based on this finding, 11 patients with right kidney cancer combined with venous tumor thrombus, admitted to Shandong Provincial Hospital Affiliated to Shandong First Medical University from June 2016 to December 2019, were retrospectively analyzed. The average age of the patients was(58.7±6.8)(45-68) years old. The CT three-dimensional reconstruction of the renal blood vessels was shown on the sagittal plane of the right margin of the aorta before the operation, and the right renal artery was detected to locate above the left renal vein in 0 cases, posterior in 7 cases, and lower in 4 cases. On the sagittal plane of the left margin of the inferior vena cava, the right renal artery was detected to locate above the left renal vein in 0 case, behind in 3 cases, and below in 8 cases. Renal tumors are located in the upper middle in 5 cases and in the lower middle in 6 cases. The maximum diameter of the tumor to be resected was 8.5-12.0 cm, with an average of (10.0±1.4) cm. Among them, 4 cases had Mayo grade 0 tumor thrombus, 4 cases were grade Ⅰ tumor thrombus, and 3 cases were grade Ⅱ tumor thrombus. All 11 cases underwent transperitoneal laparoscopic surgery. During the operation, it was found that the relationship between the right renal artery and the left renal vein was consistent with the preoperative three-dimensional reconstruction of renal blood vessels. The modified right renal artery dissection method was used, that is, the right renal artery was detected and ligated between the inferior vena cava and the aorta, using the left renal vein as a mark, and then the right kidneys and vein tumor thrombi were removed.Results:All of the 11 operations in this group were completed successfully. The operation time was (110.5±29.8)(70-150) min, the average time of right renal artery dissection was(28.5±5.8)(16- 33) min, and the amount of intraoperative bleeding was(112.7±83.5)(20-300) ml. No serious complications occurred during the operation in 11 cases. Postoperative pathological examination showed 10 cases of clear cell carcinoma and 1 case of papillary cell carcinoma. The postoperative hospital stay was 4.2 (4.18±0.75) days. There were no complications such as secondary bleeding, infection, lower extremity venous thrombosis or pulmonary embolism. All 11 patients were followed up for 3 to 42 months, with an average of(19.5±12.1) months. One patient died 23 months after the operation, and no tumor recurrence or metastasis occurred in the remaining patients.Conclusions:When the right renal artery runs to the left edge of the inferior vena cava, it is mostly behind the left renal vein. In the laparoscopic resection of right renal cancer with venous tumor thrombus, the modified right renal artery dissection method can quickly find and dissociate the right renal artery. The operation time is short, the intraoperative bleeding is less, and no postoperative complications occur.
