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）］

Background Work-related musculoskeletal disorders (WMSDs) are a major occupational health concern, particularly among workers exposed to adverse ergonomic conditions. Manganese production involves heavy physical demands, yet research on WMSDs among manganese workers remains limited. Objective To investigate the prevalence and influencing factors of WMSDs among manganese workers in a manganese enterprise in Guangxi. Methods A cross-sectional survey was conducted from May to June 2024 on workers at a manganese factory in Guangxi. The Chinese Musculoskeletal Disorders Questionnaire was used to collect information on demographic characteristics, distribution of musculoskeletal symptoms, and work-related exposures. χ² test was applied to compare differences in positive WMSDs rates across groups, and logistic regression analysis was performed to identify associated factors. Results A total of 1476 workers were enrolled in the study after pre-determined inclusion and exclusion criteria. The overall prevalence of WMSDs was 34.15%. The most commonly affected body regions were the lower back (17.28%), neck (16.67%), and shoulders (13.82%). The results of logistic regression analysis indicated that female, older age, and education level of college or above were associated with a higher risk of WMSDs (P<0.05). Awkward working postures were significantly associated with WMSDs in corresponding body regions; in particular, awkward postures of the neck, upper limbs, trunk, and lower limbs were related to an increased risk of WMSDs in multiple body sites (P<0.05). In addition, poor lighting conditions, high workplace temperature, frequent or sustained arm support during work, and high job demands were associated with an increased risk of overall or site-specific WMSDs (P<0.05). Conclusion The high prevalence of WMSDs among manganese workers is closely associated with demographic characteristics, working postures, and work environment and organizational factors. Targeted ergonomic interventions focusing on high-risk body regions and key ergonomic exposures are warranted to reduce the risk of WMSDs among manganese workers.

Purpose: Our previous study showed that circulating tumor cell (CTC) count combined with gene mutation detection might help differentiate benign and malignant pulmonary nodules (PNs). Herein, we aimed to expand the study cohort and conduct further sequencing analysis. Materials and Methods: Patients with PNs were included, and CTCs were identified before operation. Low-coverage whole-genome sequencing (LC-WGS) and lung cancer-related targeted gene sequencing were performed on CTCs. The diagnostic efficacy was evaluated by receiver operating characteristic (ROC) curve. The differences in CTC counts among subgroups classified by demographic–clinical characteristics were analyzed. LC-WGS–based copy number variation (CNV) analysis and targeted gene mutation analysis were conducted. Results: A total of 172 patients were included. CTC count of 2.5 was identified by the ROC curves as the optimal diagnostic cutoff. The sensitivity and specificity of CTC count for differentiating benign and malignant PNs were 54.2% and 78.6%, respectively. The diagnostic sensitivity and specificity of combined CTC count, radiological nodule type, and any malignant imaging features were 84.7% and 71.4%, respectively. The CTC counts were significantly greater in patients with aggressive tumors, later stage, and spread through air spaces. CTCs from malignant cases had more CNVs than those from benign cases. Conclusion CTC count can be used in identifying malignant PNs. The diagnostic efficacy can be improved if combined with computed tomography imaging characteristics. Further CNV analysis might help differential diagnosis. Greater CTC count might suggest more aggressive tumors. CTC detection can provide important information and guidance for subsequent management of PNs.

Introduction: The 2021 IDF-DAR risk calculator had been previously evaluated in multiple studies and subsequently widely accepted and applied in clinical practice as a practical standardized tool for patient risk stratification. Recently updated, the 2026 IDF-DAR Risk calculator enables a more individualized, evidence-related evaluation of patientrelated and disease-related risk factors, incorporating modern diabetes technologies, including continuous glucose monitoring (CGM), automated insulin delivery (AID) systems, and advanced insulin formulations to enhance risk stratification. This tool allows medical professionals to tailor Ramadan practices based on overall factors toward promoting safe fasting. Methodology: This prospective multicentre observational study recruited adults with Type 1 and Type 2 diabetes attending public hospitals nationwide. People with diabetes (PwD) intending to perform Ramadan fasting were invited to participate and assessed using the 2026 IDF-DAR Risk Calculator in the 6-week pre-Ramadan period between 30th January and 19th March 2026. Results: A total of 458 PwD were evaluated and stratified into low (15.7%), moderate (41%), and high risk (43.3%) categories. Most participants had Type 2 diabetes (83.6%), with 60.3% having a disease duration exceeding 10 years and 43% exhibiting poor glycemic control (hemoglobin A1c >9%). Insulin therapy was used by 76.4% of participants, including two individuals with Type 1 diabetes using AID systems. Most participants reported no recent hypoglycemia (76.4%), 81.0% performed glucose monitoring, and 3.3% used CGM. Severe comorbidities were uncommon, with 1.1% having unstable macrovascular disease and 4.4% advanced chronic kidney disease (estimated glomerular filtration rate <30). Notably, 72.2% received structured Ramadan education. Conclusion Majority of PwD attending tertiary diabetes clinics were in the moderate- to high-risk category and intended to fast despite medical advice against fasting in some cases. Although most participants were on insulin therapy, hypoglycemia was low in the pre-Ramadan period. Integration of modern technologies, advanced insulin therapies, and structured education may support safer fasting practices.

Objective:To discuss the promotive effect of Shengji Yuhong Ointment extract(SYOE)on skin wound healing of zebrafish,and to clarify its mechanism.Methods:A total of 320 wild-type AB strain zebrafish were used to establish a wound model by making an incision on the lateral abdomen.The zebrafish were randomly divided into control group,low dose of SYOE group(raised in water containing 0.625 mg·L-1 SYOE),high dose of SYOE group(raised in water containing 1.250 mg·L-1 SYOE),and allantoin group(raised in water containing 1.000 mng·L-1 allantoin),and there were 80 zebrafish in each group.The wound areas were recorded by photographs on days 7,14,and 21 after injury,and the wound healing rates were calculated.The skin tissue samples from the wound sites of the zebrafish in various groups were collected at different time points to prepare histological sections.HE staining was used to observe the widths of skin wound edges of the zebrafish on days 0,7,14,and 21 in various groups;Sirius red staining was used to detect the collagen levels in the wound tissues of the zebrafish on days 2,4,6,and 8 after injury in various groups;enzyme-linked immunosorbent assay(ELISA)was used to detect the levels of type Ⅰ collagen(Col Ⅰ)and α-smooth muscle actin(α-SMA)in the wound tissues on day 4 after injury;real-time quantitative PCR(RT-qPCR)was used to analyze the mRNA expression levels of Col Ⅰ-encoding genes(col1a1a,col1a1b,and col1a2)and α-SMA as wall as key factors of the transforming growth factor β(TGF-β)/Smad signaling pathway(tgfb1a,smad2,and smad3a)in the wound tissues of the zebrafish in various groups on day 4 after injury.Results:The wound healing assessment results showed that compared with control group,the wound healing rates of the zebrafish in low dose of SYOE group,high dose of SYOE group,and allantoin group were significantly increased on days 7,14,and 21 after injury(P＜0.05 or P＜0.01);the wound healing rate in high dose of SYOE group achieved 84％on day 21.The HE staining results showed that compared with control group,the widths of skin wound edges of the zebrafish in low dose of SYOE group,high dose of SYOE group,and allantoin group were significantly decreased on days 14 and 21 after injury(P＜0.05 or P＜0.01).The Sirius red staining results showed that compared with control group,the collagen levels in the skin wound tissue of the zebrafish in low dose of SYOE group,high dose of SYOE group,and allantoin group were significantly increased on days 6 and 8 after injury(P＜0.01).The ELISA results showed that on day 4 after injury,compared with control group,the levels of Col Ⅰ and α-SMA in the skin wound tissue of the zebrafish in low dose of SYOE group,high dose of SYOE group,and allantoin group were significantly increased(P＜0.05 or P＜0.01).The RT-qPCR results showed that on day 4 after injury,compared with control group,the expression levels of col1a1b,col1a2,α-SMA,tgfb1a,and smad2 mRNA in the skin wound tissue of the zebrafish in low dose of SYOE group were significantly increased(P＜0.05 or P＜0.01),while the expression levels of col1a1a,col1a1b,col1a2,α-SMA,tgfb1a,smad2,and smad3a mRNA in the skin wound tissue of the zebrafish in high dose of SYOE group and allantoin group were significantly increased(P＜0.01).Conclusion:SYOE can increase the collagen deposition in skin wound of zebrafish,promote wound healing,and upregulate the expression of genes related to the TGF-β/Smad signaling pathway.

Objective To explore the clinical efficacy of the medicated stick massage at meridian knot points in treating Qi stagnation and blood stasis type lumbar disc herniation(LDH)based on the meridian theory.Methods The patients with LDH in the ward 5 of orthopedics department in this hospital from Sep-tember 2024 to April 2025 were selected as the research subjects.On the basis of routine treatment and care,the control group adopted the medicated stick massage at points,while the experimental group adopted the medicated stick massage at meridian knots.The visual analogue scale(VAS)scores,Japanese Orthopaedic So-ciety(JOA)score,TCM syndrome scores and TCM syndrome therapeutic effects before intervention and in two weeks after intervention were compared between the two groups.Results The VAS scores,each item score and total score of JOA,TCM syndrome scores and TCM therapeutic effects after 2-week intervention in the experimental group all were superior to those in the control group,and the differences were statistically significant(P＜0.05).Conclusion Selecting the medicated stick massage at the meridian knots under the guidance of meridian theory could significantly improve the pain symptoms,lumbar function,TCM syndrome scores,the therapeutic effects are definite,and is worthy of clinical promotion and application.

OBJECTIVE To investigate the differential expression of CXC chemokine receptor 1(CXCR1)in chronic rhinosinusitis(CRS)and its correlation with neutrophil infiltration.METHODS A total of 60 CRS patients with nasal polyps(CRSwNP group),30 CRS patients without nasal polyps(CRSsNP group),and 30 patients with deviated nasal septum(control group)were enrolled in this study.ELISA,immunohistochemistry,and reverse transcription polymerase chain reaction were employed to measure CXCR1 expression levels.Correlation analysis was conducted to evaluate the relationship between CXCR1 expression,neutrophil infiltration,and clinical symptom scores.RESULTS CXCR1 was highly expressed in both tissues and serum of CRSwNP patients.Serum CXCR1 levels showed positive correlations with peripheral blood neutrophil counts(r=0.363,P=0.004 4),neutrophil percentage(r=0.323,P=0.011 7),visual analog scale(VAS)score(r=0.328,P=0.010 5),Lund-Kennedy endoscopic score(r=0.331,P=0.009 9),and Lund-Mackay CT score(r=0.262,P=0.045 0).Tissue CXCR1 levels were positively correlated with tissue neutrophil counts(r=0.506,P=0.011 6)and percentage(r=0.564,P=0.004 1).CONCLUSION CXCR1 is highly expressed in CRSwNP patients,and its expression level is positively correlated with the degree of neutrophil infiltration and clinical symptom scores.Higher CXCR1 levels are associated with increased neutrophil migration in both serum and tissues,as well as more severe clinical symptoms.

Objective:To investigate the effect of aortic root repair and replacement on the surgical effect and postoperative complications of Stanford type A aortic dissection.Methods:By retrospective case-control study, 190 patients with Stanford type A aortic dissection admitted to the Affiliated Hospital of Jining Medical College from August 2020 to December 2023.According to the different surgical treatment methods, they were divided into repair group ( n=65) and replacement group ( n=125). Patients in the repair group received aortic root repair, while patients in the replacement group received aortic root replacement, that was, Bentall operation. The surgical related indexes, surgical effect, postoperative outcome and mid-term survival rate of the two groups were compared. The measurement data conforming to the normal distribution were expressed by the mean standard deviation ( ± s), and the comparison between groups adopted t-test; The measurement data of skewed distribution were expressed by M( Q1, Q3), and the comparison between groups was conducted using the rank sum test. Counting data were expressed by the number of cases and percentage (%), and the comparison between groups was conducted by chi-square test or Fisher exact probability method. Results:There was no significant difference in distal aortic operation, cardiopulmonary bypass time, hypothermic circulatory arrest time and occlusion time between repair group and replacement group ( P>0.05).There was no significant difference in ventilator-assisted time, intensive care unit stay time, visual analogue score(VAS) after waking up and hospitalization time between repair group and replacement group ( P>0.05).There was no significant difference between the two groups in 30-days mortality rate after discharge (9.2% vs 11.2%) and postoperative complications (18.5% vs 22.4%) ( P>0.05). Kaplan-Meier survival curve analysis showed that there was no significant relationship between the medium-term survival rate of patients in repair group and replacement group ( χ2=0.46, P=0.500). During the follow-up period, one patient in the replacement group underwent reoperation, including Bentall operation, with an interval of 14 months. Conclusions:the choice of aortic root repair or replacement has no effect on the surgical effect and postoperative complications of Stanford A aortic dissection patients. The short-term and medium-term survival rate of aortic root repair is similar to that of replacement, and no patient received proximal surgery again during the follow-up period, which is feasible and safe.

Objective:To investigate the risk factors of skin adverse events associated with immune checkpoint inhibitor (ICI) therapy in patients with urologic neoplasms, and establish a predictive model.Methods:A single-center retrospective case-control study enrolled 91 advanced urologic neoplasms patients who received ICI therapy at the Department of Urology, Beijing Friendship Hospital, Capital Medical University from January 2020 to June 2025. Patients were divided into the skin lesion group ( n=44) and the control group ( n=47). Patients in the skin lesion group experienced related skin adverse events during ICI treatment, while patients in the control group did not experience such events during ICI treatment. The general data and laboratory indicators were compared between the two groups. The normally distributed measurement data were expressed as mean±standard deviation ( ± s), and the independent sample t-test was used for comparison between groups; the non-normally distributed measurement data were expressed as the median (interquartile range) [ M ( Q1, Q3)], and the Kruskal-Wallis test was used for comparison between groups. The count data were expressed as the number of cases and percentages, and the Chi-test was used for comparison between groups. First, a univariate analysis was conducted on the influencing factors of skin adverse events in patients with urologic neoplasms after ICI treatment. Then, the indicators with statistically significant differences in the univariate analysis were further included in the multivariate Logistic regression model to screen the independent risk factors for predicting skin adverse events. The R software was used to incorporate the factors with significant differences from multivariate analysis into the prediction model and construct a Nomogram. The calibration curve was utilized to evaluate the consistency between predicted values and actual observed results. Meanwhile, the discrimination of the model was verified by the receiver operating characteristic (ROC) curve and the area under the curve (AUC), so as to comprehensively verify the reliability and clinical application value of the prediction model. Results:The results of univariate analysis showed that there were statistically significant differences between the skin lesion group and the control group in terms of the proportion of other immune responses, serum albumin level, absolute eosinophil count, and C-reactive protein (CRP) levels ( P<0.05). These factors were included in multivariate Logistic regression, which identified elevated absolute eosinophil count and elevated CRP as the independent risk factors for related skin adverse events in patients with urologic neoplasms after ICI treatment. A predictive nomogram was built based on these factors. The calibration curve showed high consistency between predicted and actual probabilities, and ROC analysis confirmed the combined model had high predictive value (AUC=0.883, P<0.001). Conclusions:Elevated absolute eosinophil count and elevated CRP level are independent predictors of immune-related skin adverse events in urologic neoplasms patients after ICI treatment. The prediction model constructed based on these two factors facilitates early clinical screening and identification of high-risk patients.

Gastric polyps, as a common digestive system disease, have shown an increasing detection rate and are regarded as one of the precancerous states of gastric cancer. In TCM, gastric polyps can be classified as diseases such as "stomachache" and "fullness and distension in the stomach". TCM holds that the disease is often related to the accumulation of pathogenic factors such as phlegm and blood stasis in the body to form "kenang", which has the characteristics of insidiousness, stubbornness, and recurrence. Deficiency of healthy qi and disorder of qi movement can lead to the adhesion of phlegm and blood stasis, which highly aligns with the etiology and pathogenesis of gastric polyps. The treatment principles are promoting blood circulation to remove blood stasis, regulating qi movement, and strengthening the body resistance to consolidate the essence. Understanding the etiology, pathogenesis, and treatment principles of gastric polyps from the theory of "kenang" has important guiding significance for clinical diagnosis and treatment, providing new ideas and methods for the treatment of gastric polyps.
