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）］

Objective To explore the effect of long non-coding RNA (lncRNA) NUTM2A-AS1 on the damage of vascular endothelial cells induced by oxidized low density lipoprotein (oxLDL) and its molecular mechanism. Methods Human umbilical vein endothelial cells(HUVECs) were cultured in DMEM medium. The HUVECs treated with 100 μg/mL oxLDL were assigned to oxLDL group, while those cultured under normal conditions were assigned to Con group. After transfection of the lncRNA NUTM2A-AS1 interference expression vector and negative control, microRNA-129-5p mimic and negative control into HUVECs, the cells treated with 100 μg/mL oxLDL were assigned to oxLDL+si-NUTM2A-AS1 group, oxLDL+si-NC group, oxLDL+miR-129-5p group, and oxLDL+miR-NC group, respectively. After co-transfection of the lncRNA NUTM2A-AS1 interference expression vector and miR-129-5p inhibitor or negative control into HUVECs, the cells treated with 100 μg/mL oxLDL were assigned to oxLDL+si-NUTM2A-AS1+anti-miR-129-5p group and oxLDL+si-NUTM2A-AS1+anti-miR-NC group. The levels of malondialdehyde (MDA) in cells, as well as the activities of superoxide dismutase (SOD) and glutathione peroxidase (GSH-Px) were measured using kits. Cell apoptosis was detected by flow cytometry. Protein expression was detected by Western blot. The targeting relationship between NUTM2A-AS1 and miR-129-5p was detected by dual luciferase reporter assay and RNA pull-down experiments. Results Compared with the Con group, the expression level of lncRNA NUTM2A-AS1 was increased, the expression level of miR-129-5p was decreased, the content of MDA was increased, the activities of SOD and GSH-Px were decreased, the apoptosis rate of vascular endothelial cells and the expression levels of cleaved-caspase3 and cleaved-caspase9 were increased in the oxLDL group (P < 0.05). After interference of lncRNA NUTM2A-AS1 expression or overexpression of miR-129-5p, the content of MDA was decreased, the activities of SOD and GSH-Px were increased, cell apoptosis was reduced (P < 0.05). The damage to vascular endothelial cells mediated by knockdown of lncRNA NUTM2A-AS1 under oxLDL conditions can be reversed by downregulation of miR-129-5p. LncRNA NUTM2A-AS1 targeted miR-129-5p for regulation. Conclusion Interference of lncRNA NUTM2A-AS1 expression can inhibit oxLDL-induced vascular endothelial cell damage by targeting miR-129-5p for upregulation.

Objective To explore the clinical features,treatment and prognosis of glioblastomas(GBM)in adults.Methods A retrospective cohort study was performed on 176 adult GBM patients admitted to our department from January 2015 to December 2021.Chi-square test was used to investigate the clinical differences between isocitrate dehydrogenase(IDH)mutant and wild-type GBM.Kaplan-Meier and Log-Rank tests were employed to plot survival curve and compute the survival analysis.Multivariate Cox regression model was applied to identify the independent prognostic factors.Results IDH wild-type GBM account for 89.2％and had significantly differences from the IDH-mutant GBM in terms of age of onset,Karnofsky(KPS)score at admission,symptoms of neurological deficit,and methylation status of O6-methylguanine-DNA-methyltransferase(MGMT)promoter(P＜0.05).For the IDH wild-type GBM patients receiving conventional therapy,univariate Cox hazard analysis showed gross total resection,methylation of MGMT promoter,initiation of radiation within the 5th to 6th week after surgery,and adjuvant temozolomide(TMZ)chemotherapy ≥6 cycles were favorable prognostic factors for overall survival(OS);GBMs in the left hemisphere,involvement of single lobe,methylation of MGMT promoter,and initiation of radiation within the 5th to 6th week after surgery were favorable prognostic factors for progression free survival(PFS)(all P＜0.05).Moreover,multivariate Cox hazard regression analysis indicated that methylation of MGMT promoter,and initiation of radiation within the 5th to 6th week after surgery,and adjuvant TMZ chemotherapy ≥6 cycles were independent protective factors for OS,and GBMs in the left hemisphere,involvement of single lobe and methylation of MGMT promoter were independent protective factors for PFS in the GBM patients(all P＜0.05).Conclusion The clinical and prognostic features are totally different between IDH mutant and wild-type GBM,and molecular detections are needed for the further pathological classification.Methylation of MGMT promoter is a primary marker of favorite prognosis for IDH wild-type GBM,and slightly delay in radiotherapy(the 5th to 6th week after surgery)can effectively improve the survival prognosis of IDH wild-type GBM.

Objective To investigate the levels of N-terminal probrain natriuretic peptide(NT-proBNP),thrombolomodulin(TM),C-type lectin-like receptor 2(CLEC-2),galectin-3(Gal-3)and their relationships with prognosis in patients with acute coronary syndrome(ACS)after percuta-neous coronary intervention(PCI).Methods A total of 80 patients with ACS were selected as study objects.The patients were followed up for 6 months by outpatient visit or telephone follow-up,and the occurrence of major adverse cardiovascular events(MACE)was recorded in the patients.According to the occurrence of MACE,patients were divided into MACE group(26 cases)and control group(54 cases).The changes of serological indexes were compared between the two groups.Results The expression levels of NT-proBNP,CLEC-2,TM and Gal-3 in serum of patients in the MACE group were significantly higher than those of control group(P＜0.05).Multivariate Logistic regression analysis showed that NT-proBNP,CLEC-2,TM,and Gal-3 were all influential factors for the occur-rence of MACE after PCI in ACS patients(P＜0.05).Conclusion NT-proBNP,CLEC-2,TM and Gal-3 are influencing factors for MACE in patients with ACS after PCI,and have a good predictive role in evaluating the occurrence of MACE.

Objective:To observe any effect of task-oriented training in the activities of daily living (ADL) for stroke patients.Methods:Sixty-two hemiplegic stroke survivors were randomly divided into an experimental group and a control group, each of 31. In addition to routine occupational therapy, the control group exercised on their own, while the experimental group underwent 45-minute task-oriented training sessions based on ADL action analysis every day, 5 days a week for 6 weeks consecutively. Before and after the treatment the upper limb functioning of both groups was quantified using Fugl-Meyer upper limb motor function scoring (FMA-UE) and Brunnstrom staging (BSS). ADL skill was assessed using the modified Barthel index (MBI).Results:After the treatment, the average FMA-UE and MBI scores of both groups were significantly better than before the treatment and better than the control group′s averages. The average BSS scores had also improved significantly, with that of the experimental group significantly better than the control group′s average.Conclusions:Task-oriented training based on ADL motion analysis can significantly improve upper limb motor functioning and ADL ability after a stroke despite hemiplegia. Its efficacy is better than that of conventional occupational therapy alone.

Objective:To explore the relationship between work stress, sense of coherence (SOC) and compassion fatigue (CF) among oncological nurses, and to study the mediating role of SOC between work stress and CF in oncological nurses.Methods:Totally 370 oncological nurses from 7 ClassⅢ Grade A hospitals in Anhui Province between November 2019 and January 2020 were conveniently selected and investigated with the Chinese Nurse Work Stressor Scale, Sense of Coherence Scale-13, Professional Quality of Life and the general information questionnaire. AMOS 21.0 and SPSS 23.0 were used for statistical analysis of the data. A total of 370 questionnaires were distributed and 345 valid questionnaires were returned.Results:The work stress of oncological nurses was negatively correlated with their SOC ( r=-0.547, P<0.01) , and positively correlated with job burnout and secondary trauma ( r=0.607, 0.418; P<0.01) ; SOC was negatively correlated with job burnout and secondary trauma ( r=-0.581, -0.405; P<0.01) . SOC played a mediating role between the work stress, job burnout and secondary trauma of oncological nurses, and the mediating effect accounted for 45.81% and 33.82% of the total effect, respectively. Conclusions:SOC is a mediating variable between the work stress and CF of oncological nurses. Actively assessing the level of nurses' SOC and providing interventions are helpful to reduce CF caused by work stress.

Objective To explore the clinical effect of training assisted by a lower limb rehabilitation robot on the bladder and intestinal function of paraplegic spinal cord injury survivors. Methods Thirty-eight paraplegic patients with spinal cord injury were divided according to their admission order into an experimental group ( n=19) and a control group (n=19). Both groups were given conventional rehabilitation training, while the experimental group was additionally provided with robot-assisted lower limb training in three stages:adaptation, training and con-solidation. It lasted 30 minutes daily, 5 days per week for 12 weeks. Before and after the training, an urodynamics examination system was used to evaluate the maximum urine flow, bladder capacity, residual urine volume, bladder pressure and detrusor pressure. Colon transit time, mean rectal pressure and intestinal function were measured using the colon transit test, a mean rectal pressure test, and the Functional Independence Measure ( FIM) scale respective-ly. Results The average bladder volume, maximum urine flow rate, average urine flow rate, detrusor pressure, bladder compliance, average rectal pressure and intestinal FIM score of the robot training group after training were all significantly better than before the training, as were the average residual urine volume and colon transit time. After the training, the average bladder volume, maximum urine flow rate, average urine flow rate, detrusor pressure, bladder compliance and average rectal pressure of the robot training group were all significantly higher than those of the control group, while the average residual urine volume and colon transit time were significantly smaller. Then, 32％ of the patients in the experimental group achieved no less than 6 points for their average FIM score, significantly higher than in the control group. Conclusion Robot-assisted lower limb training combined with comprehensive rehabilitation training can effectively improve the bladder and intestinal function of paraplegic patients after a spinal cord injury.

Objective:To discuss the efficacy of emergency endoscopic hemostasis combined with somatostatin in treatment of upper gastrointestinal hemorrhage.Methods:100 patients with upper gastrointestinal hemorrhage were selected and divided into two groups randomly.The control group (48 cases) was given conventional hemostatic measures.The observation group (52 cases) was given emergency endoscopic hemostasis combined with somatostatin.The efficacy of emergency endoscopic hemostasis combined with somatostatin in treatment of upper gastrointestinal hemorrhage was evaluated by efficacy,the curative success rate and the improvement situation of clinical symptoms.Results:The effective rate was 88.5 ％ in the observation group,and the effective rate was 70.8 ％ in the control group,and the effective rate of observation group was higher than that of the control group (P＜0.05).The success rate for different lesion size was higher in the observation group compared with control group (P＜0.05).According to the success rate,with the increased size of lesion,the hemostasis rate was decreased.The hospitalization,negative fecal occult and haematemesis disappeared time of observation group was shorter than that of the control group (P＜0.05).The postoperative bleeding rate of observation group was lower than that of the control group (P＜0.05).Conclusions:The emergency endoscopic hemostasis combined with somatostatin has a good therapeutic effect on upper gastrointestinal hemorrhage.It can improve the clinical symptoms and shorten the hospitalization time,but its effect is limited on large lesion of upper gastrointestinal hemorrhage.
