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 investigate and compare the effects of electroacupuncture and dexamethasone on lung function and histomorphology and behavior in the offspring of perinatal nicotine exposure(PNE)rats.Methods Twenty-four pregnant Sprague-Dawley rats were randomly divided into control,model,electroacupuncture shallow needling,and dexamethasone groups using the random number table method(n=6 rats per group).A pulmonary dysplasia model in offspring rats with PNE was prepared by cervicodorsal subcutaneous injection with nicotine,and successful establishment of the model was confirmed by demonstrating statistically significant differences in growth parameters,lung function,and lung morphology compared to the control group.From the sixth day of maternal conception,the control group received cervicodorsal subcutaneous injection with 0.9%sodium chloride solution(1 mg/kg once per day),and the remaining groups were similarly injected with nicotine(1 mg/kg once per day).Concurrent with the nicotine injections,the electroacupuncture shallow needling group received electroacupuncture interventions at the"Zusanli"(ST 36)acupoint on both sides once a day for 20 min.In contrast,the offspring rats in the dexamethasone group received intraperitoneal dexamethasone injections from postnatal day 8(1.5 mg/kg once per day for 3 days),with a later dose of 0.75 mg/kg once per day for 4 days.Following successful model establishment,four offspring per rat were retained in each group using the random number table method.Until the 21st day after the birth of the offspring,using the random number table method,one offspring randomly selected from the four retained offspring per rat in each group was assigned to growth parameter assessment including body weight,lung weight,and lung index;simultaneously,one offspring was randomly selected for pulmonary function which was detected by a small animal pulmonary function machine,with the parameters of forced vital capacity(FVC),functional residual capacity(FRC),dynamic lung compliance(Cdyn),peak expiratory flow(PEF),peak inspiratory flow(PIF),and airway resistance(RL);concurrently,one offspring was randomly selected for hematoxylin and eosin staining to observe the histomorphology of the lung tissue,alveolar numbers,and mean alveolar septal thickness;additionally,one offspring was randomly selected for Morris water maze testing to evaluate the effects of the two intervention methods on learning and memory capabilities in offspring rats with PNE.Results Compared with the control group,the body weight,lung weight,lung index,FVC,PEF,FRC,Cdyn,alveolar number,platform crossing times,target quadrant time percentage,and target quadrant path percentage in the Morris water maze experiment were significantly decreased in the offspring rats of the model group(P<0.01).In contrast,PIF,RL,average thickness of alveolar septa,and latency of the Morris water maze experiment were significantly increased in the offspring rats of the model group(P<0.01).Compared with the model group,both electroacupuncture shallow needling group and dexamethasone group exhibited significant increases in body weight,lung weight,lung index,FVC,PEF,FRC,Cdyn,and alveolar numbers(P<0.05,P<0.01),along with significant decreases in PIF,RL values,and mean alveolar septal thickness(P<0.01).However,in the Morris water maze experiment,compared with the model group,the electroacupuncture shallow needling group demonstrated significantly more platform crossing times and a higher target quadrant time percentage and target quadrant path percentage(P<0.01),coupled with reduced latency period(P<0.01),whereas the dexamethasone group showed no significant differences compared to the model group.Compared to the electroacupuncture shallow needling group,the dexamethasone group showed significantly less platform crossing times and a lower target quadrant time percentage and target quadrant path percentage,coupled with increased latency period(P<0.01).Conclusion Both electroacupuncture and dexamethasone demonstrated protective effects on lung development in PNE offspring rats by ameliorating lung histomorphology and pulmonary function.However,offspring receiving late,small-dose,short-course dexamethasone exhibited inferior learning and memory capabilities,whereas the electroacupuncture group showed significantly superior cognitive performance compared to the dexamethasone group.

Aim To verify the therapeutic effect of the Qushi Huoxue decoction(QSHXF)on a mouse model of non-alcoholic fatty liver disease(NAFLD)using network pharmacology and experimental approaches,to examine the changes in the PI3K-AKT-lipid metabo-lism signaling pathway,and to elucidate its molecular mechanisms.Methods The potential active ingredi-ents and targets of the QSHXF were identified using the TCMSP platform.NAFLD-related genes were sourced from the GeneCards,PharmGkb,TTD,and OMIM data-bases.The intersection of drug targets and NAFLD treatment targets was analyzed to identify the key tar-gets of the QSHXF in treating NAFLD.The STRING database and Cytoscape 3.9.1 software were utilized to construct networks linking traditional Chinese medicine active ingredients to disease targets and PPI networks,allowing for the screening of key active ingredients and core targets.GO and KEGG enrichment analyses of the intersecting targets were conducted using R version 4.2.2.The NAFLD model was established by feeding mice a methionine-choline deficient diet for a duration of five weeks.Following successful modeling,low,me-dium,and high doses of the QSHXF were administered for intervention over a period of six weeks.The efficacy was verified and the underlying mechanisms were ex-plored using methods such as HE staining,Oil Red O staining,and Western blot analysis.Results The net-work pharmacology prediction indicated that QSHXF might effectively treat NAFLD through key components such as quercetin and kaempferol,as well as core tar-gets including STAT3,AKT1,and HIF1A.KEGG en-richment analysis further suggested that QSHXF might exert its therapeutic effects on NAFLD via signaling pathways such as AGE-RAGE and PI3K-AKT.Verifi-cation through animal experiments demonstrated that QSHXF could significantly reduce hepatic steatosis and lipid droplet accumulation in NAFLD mice.Specifical-ly,it markedly decreased serum levels of TC,TG,ALT,AST,and LDL,while increasing HDL levels.Addition-ally,the treatment significantly reduced the protein ex-pression levels of p-PI3K,p-AKT,SREBP-1c,FASN,and ACC1 in the liver.Conclusions QSHXF can sig-nificantly enhance liver function,improve blood lipid levels,and alleviate hepatic steatosis in NAFLD mice,with its mechanism potentially linked to the inhibition of the PI3K-AKT-lipid metabolism signaling pathway.

Objective To explore the correlation between residual cholesterol(RC)and lipoprotein-associated phospholipase A2(Lp-PLA2)in type 2 diabetes mellitus(T2DM).Methods A total of 362 T2DM patients visited our hospital from January 2022 to June 2023 were divided into RC≥0.78 mmol/L(HRC,n=196)group and RC<0.78 mmol/L(NRC,n=166)group based on the levels of RC.The clinical characteristics and related factors were compared between the two groups and the risk factors for RC were analyzed.Results Compared with NRC group,DM duration,SBP,DBP,TC,TG,rate of ACEI or ARBs use,non-HDL-C,Lp-PLA2 and IMT in HRC group increased(P<0.05)and LDL-C decreased(P<0.05).Pearson and Spearman correlation analysis showed that RC was positively correlated with age,DM duration,SBP,DBP,TC,TG,non-HDL-C,Lp-PLA2,IMT(P<0.05)and negatively correlated with LDL-C(P<0.05).Logistic multivariate regression analysis showed that TC,TG,LDL-C,non-HDL-C,Lp-PLA2 and IMT were the influencing factors of RC in T2DM patients.Receiver operating characteristic curve analysis showed that the cutoff value of RC was 0.85 mmol/L,and the cutoff value of Lp-PLA2 was 242 U/L.The predicted AUC of T2DM macroangiopathy respectively was 0.864 and 0.721,and the predicted AUC of RC combined with Lp-PLA2 was 0.896.Conclusions Serum RC is positively correlated with Lp-PLA2 in T2DM patients.The combined detection of these two indicators has a certain predictive value for T2DM macrovascular disease.

Objective:To analyze the incidence rate and disability-adjusted life year (DALY) rate of Chlamydia trachomatis ( C. trachomatis) infection in women aged 15-49 years in China from 1990 to 2021, identify the vulnerable populations, and provide evidence for the prevention and control of C. trachomatis infection. Methods:The data from Global Burden of Disease Study 2021 were used to analyze the incidence rate and DALY rate of C. trachomatis infection in women aged 15-49 years in China from 1990 to 2021 by using Joinpoint regression model. The age-period-cohort analysis method was used to decompose the age effect, period effect and cohort effect of incidence rate and DALY rate of C. trachomatis infection. Results:From 1990 to 2021, the incidence rate of C. trachomatis infection increased from 5 892.02/100 000 in 1990 to 7 402.23/100 000 in 2021 in women aged 15-49 years in China. The DALY rate increased from 1.92/100 000 person-years in 1990 to 2.00/100 000 person-years in 2021. Joinpoint regression showed that, from 1990 to 2021, the annual incidence of C. trachomatis infection in Chinese women age aged 15-49 years increased by 0.74% [average annual percent change (AAPC) =0.74%, 95% CI: 0.67%-0.81%, t=21.94, P<0.001] and the annual average DALY rate increased by 0.11% (AAPC=0.11%, 95% CI: -0.09%-0.30%, t=1.06, P=0.287). Age-period-cohort model analyses showed that women aged 30-34 years were at high risk to be infected with C. trachomatis and women aged 40-44 years were at high risk to have high DALY. The period effect showed that the risk for C. trachomatis infection began to increase in 1990, peaked during 2000-2004, then gradually decreased. During 2015-2019, the infection risk increased again, while the risk for high DALY showed a decreasing trend. The cohort effect showed that the risks for C. trachomatis infection and DALY were lower in later birth cohorts. Conclusions:From 1990 to 2021, the incidence rate and DALY rate of C. trachomatis infection showed fluctuations in women aged 15-49 years in China. It is necessary to pay close attention to the prevention and control of C. trachomatis infection in women aged 30-34 years.

OBJECTIVE To summarize the current situation of pharmaceutical clinic service in our hospital over the past five years， and explore sustainable development strategies for service models of pharmaceutical clinics. METHODS A retrospective analysis was conducted on the consultation records of patients who registered and established files at the pharmaceutical clinic in our hospital from January 2019 to December 2023. Statistical analysis was performed on patients’ general information， medication- related problems， and types of pharmaceutical services provided by pharmacists. RESULTS A total of 963 consultation records were included， among which females aged 20-39 years accounted for the highest proportion （66.04%）； obstetrics and gynecology- related consultations accounted for the largest number of cases. Additionally， 80 patients attended follow-up visits at our hospital’s pharmaceutical clinic. A total of 1 029 medication-related issues were resolved， including 538 cases of drug consultations （52.28%）， 453 medication recommendations （44.02%）， 22 medication restructuring（2.14%）， and 16 medication education （1.55%）； the most common types of medication-related problems identified were adverse drug events（70.07%）. CONCLUSIONS Although the pharmaceutical clinic has achieved recognition from clinicians and patients， challenges such as low awareness among healthcare providers and the public persist. Future efforts should focus on strengthening information technology construction， enhancing pharmacist training， and establishing various forms of outpatient pharmaceutical service models.

Objective:To evaluate the diagnostic value of coronary angiography-derived fractional flow reserve (FFR) and index of microcirculatory resistance (IMR) for identifying coronary functional abnormalities.Methods:This diagnostic study enrolled patients with clinically suspected or diagnosed coronary artery disease who underwent coronary angiography at Beijing Anzhen Hospital, TEDA International Cardiovascular Hospital, and Qilu Hospital of Shandong University between December 2021 and June 2022. All enrolled patients successfully underwent invasive wire-based FFR and IMR measurements during angiography. In a core laboratory, FFR and IMR for the target vessels were measured using artificial intelligence technology based on coronary angiographic images. Spearman correlation analysis was used to evaluate the correlation between angiography-derived FFR and wire-based FFR, and between angiography-derived IMR and wire-based IMR. Coronary hemodynamic abnormality was defined as FFR≤0.80; the diagnostic performance of angiography-derived FFR for identifying this abnormality was evaluated. Microcirculatory dysfunction was defined as IMR≥25; the diagnostic performance of angiography-derived IMR for identifying microcirculatory dysfunction was evaluated.Results:A total of 181 patients, aged (60.6±8.8) years, with 62 (34.3%) females, and 181 target vessels were included in the final analysis. Angiography-derived FFR showed a significant positive correlation with wire-based FFR ( r=0.78, P<0.001). For identifying coronary hemodynamic abnormality, angiography-derived FFR showed an accuracy of 89.0%, sensitivity of 88.8%, specificity of 89.1%, positive predictive value (PPV) of 88.8%, negative predictive value (NPV) of 89.1%, and an area under the receiver operating characteristic curve ( AUC) of 0.88. Angiography-derived IMR showed a significant positive correlation with wire-based IMR ( r=0.93, P<0.001). For identifying microcirculatory dysfunction, angiography-derived IMR demonstrated an accuracy of 89.5%, sensitivity of 86.8%, specificity of 90.2%, PPV of 70.2%, NPV of 96.3%, and an AUC of 0.95. Conclusion:Angiography-derived FFR and IMR exhibit strong correlations with their invasive wire-based counterparts and demonstrate high diagnostic value for assessing coronary hemodynamics and coronary microcirculatory function.

ObjectiveThe proteome of biological evidence contains rich genetic information, namely single amino acid polymorphisms (SAPs) in protein sequences. However, due to the lack of efficient and convenient analysis tools, the application of SAP in public security still faces many challenges. This paper aims to meet the application requirements of SAP analysis for forensic biological evidence’s proteome data. MethodsThe software is divided into three modules. First, based on a built-in database of common non-synonymous single nucleotide polymorphisms (nsSNPs) and SAPs in East Asian populations, the software integrates and annotates newly identified exonic nsSNPs as SAPs, thereby constructing a customized SAP protein sequence database. It then utilizes a pre-installed search engine—either pFind or MaxQuant—to perform analysis and output SAP typing results, identifying both reference and variant types, along with their corresponding imputed nsSNPs. Finally, SAPTyper compares the proteome-based typing results with the individual’s exome-derived nsSNP profile and outputs the comparison report. ResultsSAPTyper accepts proteomic DDA mass spectrometry raw data (DDA acquisition mode) and exome sequencing results of nsSNPs as input and outputs the report of SAPs result. The pFind and Maxquant search engines were used to test the proteome data of 2 hair shafts of2 individuals, and both obtained SAP results. It was found that the results of the Maxquant search engine were slightly less than those of pFind. This result shows that SAPTyper can achieve SAP fingding function. Moreover, the pFind search engine was used to test the proteome data of 3 hair shafts from 1 European person and 1 African person in the literature. Among the sites fully matched by the literature method, sites detected by SAPTyper are also included; for semi-matching sites, that is, nsSNPs are heterozygous, both literature method and SAPTyper method had the risk of missing detection for one type of the allele. Comparing the analysis results of SAPTyper with the SAP test results reported in the literature, it was found that some imputed nsSNP sites identified by the literature method but not detected by SAPTyper had a MAF of less than 0.1% in East Asian populations, and therefore they were not included in the common nsSNP database of East Asian populations constructed by this software. Since the database construction of this software is based on the genetic variation information of East Asian populations, it is currently unable to effectively identify representative unique common variation sites in European or African populations, but it can still identify SAP sites shared by these populations and East Asian populations. ConclusionAn automated SAP analysis algorithm was developed for East Asian populations, and the software named SAPTyper was developed. This software provides a convenient and efficient analysis tool for the research and application of forensic proteomic SAP and has important application prospects in individual identification and phenotypic inference based on SAP.
