Network pharmacology and molecular docking were employed to predict the mechanism of Zhizhu Decoction in regulating macrophage polarization to reduce adipose tissue inflammation in obese children, and animal experiments were then carried out to validate the prediction results. The active ingredients and targets of Zhizhu Decoction were retrieved from the Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform(TCMSP). The inflammation related targets in the adipose tissue of obese children were searched against GeneCards, OMIM, and DisGeNET, and a drug-disease-target network was established. STRING was used to construct a protein-protein interaction(PPI) network and screen for core targets. R language was used to carry out Gene Ontology(GO) and Kyoto Encyclopedia of Genes and Genomes(KEGG) pathway enrichment analyses. AutoDock was used for the molecular docking between core targets and active ingredients. 24 SPF grade 6-week C57B/6J male mice were adaptively fed for 1 week, and 8 mice were randomly selected as the blank group. The remaining 16 mice were fed with high-fat diet for 8 weeks to onstruct a high-fat diet induced mouse obesity model. After successful modeling, the 16 mice were randomly divided into model group and Zhizhu Decoction group, with 8 mice in each group. Zhizhu Decoction group was intervened by gavage for 14 days, once a day. Blank group and model group were given an equal amount of sterile double distilled water(ddH_2O) by gavage daily. After the last gavage, serum and inguinal adipose tissue were collected from mice for testing. The morphology of inguinal adipose tissue was observed by hematoxylin-eosin(HE) staining, the levels of inflammatory factors interleukin-6(IL-6) and tumor necrosis factor-α(TNF-α)were detected by enzyme-linked immunosorbent assay(ELISA), and the protein expression of macrophage marker molecule nitric oxide synthase(iNOS) and epidermal growth factor like hormone receptor 1(F4/80) was detected by immunofluorescence staining. Network pharmacology predicted luteolin, naringenin, and nobiletin as the main active ingredients in Zhizhu Decoction and 15 core targets. KEGG pathway enrichment analysis revealed involvement in the key signaling pathway of nuclear factor κB(NF-κB). Molecular docking showed that the active ingredients of Zhizhu Decoction bound well to the core targets. Animal experiment showed that compared with the model group, Zhizhu Decoction reduced the distribution of inflammatory cytokines in the inguinal adipose tissue of mice, lowered the levels of TNF-α and IL-6 in the serum(P<0.05, P<0.01), and down-regulated the expression of iNOS and F4/80(P<0.05). The results showed that the active ingredients in Zhizhu Decoction, such as luteolin, naringenin, and nobiletin, inhibit the aggregation of macrophages in adipose tissue, downregulate their classic activated macrophage(M1) polarization, reduce the expression of inflammatory factors IL-6 and TNF-α, and thus improve adipose tissue inflammation in obese mice.

Background Occupational disease diagnosis appraisal is an appeal procedure initiated when a party disagrees with the occupational disease diagnosis conclusion. It is a legal procedure to safeguard the health rights of employees and the legitimate rights and interests of employers. Objective To analyze the data of occupational disease diagnosis appraisal in Shanghai, identify existing problems, and provide suggestions for improving. Methods Statistical analysis was conducted on basic situation, characteristics of workers and employers, disease classification, and consistency between diagnosis and appraisal conclusions of all occupational disease diagnosis appraisal cases from 2012 to 2024. All diagnosis conclusions were named in accordance with the Classified Catalogue of Occupational Diseases included employers were classified according to the Measures for the Statistical Classification of Large, Medium, Small and Micro Enterprises" and the Notice on Adjusting the Provisions for Classifying Enterprise Registration Types; industry classification followed the Industrial Classification for National Economic Activities (GB/T 4754-2017). Results From 2012 to 2024, a total of 260 cases of occupational diseases diagnosis appraisal were closed. The main diagnosis were 138 cases of ear, nose, throat, and oral diseases (53.1%), chemical poisoning (18.8%), and pneumoconiosis and other respiratory diseases (16.2%). The proportion of ear, nose, throat, and oral diseases gradually increased (2022 excluded). The incidence of annual municipal and provincial cases decreased by 76.3% and 85.0% respectively (2024 vs 2012). The consistency rate of conclusions between appraisal and diagnosis gradually increased. The total consistency rates between final appraisals and diagnostic conclusions were 81.5%, and 79.7%, 87.8%, 100.0%, 85.0% for ear, nose, throat, and oral diseases, chemical poisoning, and pneumoconiosis and other respiratory system diseases, respectively. Specifically, the consistency rates were 80.1% and 80.0% for noise-induced deafness and chronic benzene poisoning. In terms of inconsistency reasons, "inconsistent interpretation of standards and excessive discretion in standard application" accounted for 43.8%, followed by "failure to correctly apply standards" (31.3%) and and "discrepancies in occupational exposure history recognition" (15.6%). Conclusion The revisions and improvements of the legal system for occupational disease diagnosis appraisal have played a positive role in improving the consistency of conclusions between appraisal and diagnosis of occupational diseases in Shanghai. It is suggested to further strengthening the publicity and training of occupational disease diagnosis standards to improve the quality of occupational disease diagnosis.

OBJECTIVE: To identify prognostic genes associated with lysosome-dependent cell death (LDCD) in patients with gastric cancer (GC). METHODS: Differentially expressed genes (DEGs) were identified using The Cancer Genome Atlas - Stomach Adenocarcinoma. Weighted gene co-expression network analysis was performed to identify the key module genes associated with LDCD score. Candidate genes were identified by DEGs and key module genes. Univariate Cox regression analysis, and least absolute shrinkage and selection operator regression and multivariate Cox regression analyses were performed for the selection of prognostic genes, and risk module was established. Subsequently, key cells were identified in the single-cell dataset (GSE183904), and prognostic gene expression was analyzed. Cell proliferation and migration were assessed using the Cell Counting Kit-8 assay and the wound healing assay. RESULTS: A total of 4,465 DEGs, 95 candidate genes, and 4 prognostic genes, including C19orf59, BATF2, TNFAIP2, and TNFSF18, were identified in the analysis. Receiver operating characteristic curves indicated the excellent predictive power of the risk model. Three key cell types (B cells, chief cells, and endothelial/pericyte cells) were identified in the GSE183904 dataset. C19orf59 and TNFAIP2 exhibited predominant expression in macrophage species, whereas TNFAIP2 evolved over time in endothelial/pericyte cells and chief cells. Functional experiments confirmed that interfering with C19orf59 inhibited proliferation and migration in GC cells. CONCLUSION C19orf59, BATF2, TNFAIP2, and TNFSF18 are prognostic genes associated with LDCD in GC. Furthermore, the risk model established in this study showed robust predictive power.

Objective To investigate the influence and threshold effect of preoperative intraocular pressure(IOP)on secondary glaucoma(SG)after pars plana vitrectomy(PPV).Methods A retrospective analysis was conducted on 88 patients with retinal detachment who developed SG after PPV(SG group)treatment at Hebei Eye Hospital from January 2020 to January 2024.Meanwhile,88 patients with retinal detachment who underwent PPV at the same hospital during the same period but did not develop SG postoperatively were selected as non-SG group in a 1:1 ratio.Univariate analysis was used to compare the differences in clinical data between the two groups.A stratified regression model was applied to analyze the correlation between postoperative characteristics and preoperative IOP.Multivariate logistic regression analysis was used to identify the factors affecting the occurrence of SG after PPV,with multicollinearity diagnosis and sensitivity analysis performed for the parameters.Additionally,the threshold effect of preoperative IOP on the risk of postoperative SG was analyzed.A predictive model was constructed based on the results of multivariate logistic regression.The receiver operating characteristic(ROC)curve was employed to evaluate the efficacy and accuracy of the predictive model,while the calibration curve and clinical decision curve were utilized to assess the consistency between the predictive model and actual conditions as well as the clinical practicality of the model.Results Compared with non-SG group,SG group had a higher proportion of patients with a history of diabetes,family history of glaucoma,a higher preoperative IOP,higher proportion of postoperative closed anterior chamber angle status,longer silicone oil tamponade duration(≥6 months),higher incidence of silicone oil emulsification(P<0.05).Postoperative anterior chamber angle status(closed)was significantly positively correlated with preoperative IOP levels(P<0.05).Multivariate logistic regression analysis showed that history of diabetes,family history of glaucoma,silicone oil emulsification,postoperative anterior chamber angle closure,silicone oil tamponade duration≥6 months,and preoperative IOP≥21 mmHg were independent risk factors for SG after PPV(P<0.05).Multicollinearity diagnosis indicated no significant collinearity among the above variables.Sensitivity analysis showed that the association tended to be null when E=5.014.With the increase of preoperative IOP,the probability of SG after PPV in patients showed an upward trend.The threshold effect analysis revealed that when preoperative IOP≥19 mmHg,the probability of SG after PPV increased significantly with the elevation of preoperative IOP(OR=2.942,95%CI 1.794-4.826,P<0.001).After adjusting for covariates,preoperative IOP remained an independent influencing factor for different degrees of SG after PPV(OR=7.392,95%CI 1.379-12.510,P=0.001).Before and after validation,the area under the ROC curves(AUCs)of the model for predicting SG after PPV were 0.987(95%CI 0.974-1.000,P<0.001)and 0.989(95%CI 0.969-1.000,P<0.001),with sensitivities of 0.9332 and 0.9545,and specificities of 0.9981 and 0.9773,respectively.Both the calibration curve and decision curve analysis demonstrated that the predictive model had good discrimination and accuracy.Conclusion Preoperative IOP is an influencing factor and a sensitive indicator for the development of SG after PPV in patients with retinal detachment.

Objective To analyze the application effect of multidisciplinary collaborative nursing based on the Information-Knowledge-Attitude-Practice(IKAP)theory in patients undergoing lobectomy via thoracoscopy.Methods A total of 168 patients undergoing lobectomy via thoracoscopy were se-lected,and randomly divided into control group and observation group using a random number table,with 84 patients in each group.The control group received routine nursing,while the observation group received multidisciplinary collaborative nursing based on the IKAP theory in addition to routine nurs-ing.The postoperative recovery,pulmonary function indicators[forced vital capacity(FVC),maxi-mum voluntary ventilation(MVV)and ratio of forced expiratory volume in the first second to forced vi-tal capacity(FEV1/FVC)],self-efficacy[General Self-Efficacy Scale(GSES)score]and self-man-agement ability[Chronic Disease Self-Management Questionnaire(CDSMQ)score]before and after intervention were observed and compared between the two groups.Results The observation group had shorter first ambulation time,first flatus time and length of hospital stay compared with the control group(P＜0.05).Before intervention,there were no statistically significant differences in FVC,MVV,FEV1/FVC,CDSMQ scores and GSES scores between the two groups(P＞0.05).After inter-vention,the observation group had higher FVC,MVV,FEV1/FVC,CDSMQ scores and GSES scores compared with the control group(P＜0.05).Conclusion Multidisciplinary collaborative nursing based on the IKAP theory can effectively promote the recovery process in patients undergoing lobec-tomy via thoracoscopy,improve postoperative pulmonary function,self-management ability,and self-efficacy,thereby enhancing the quality of rehabilitation.

Objective To analyze the incidence and mortality of malignant tumors among the middle-aged and elderly population in Chengguan district of Lanzhou from 2011 to 2021,and to discuss the related risk factors.Methods Using the research data of REACTION in Lanzhou,an epidemiological survey was conducted through cluster sampling in three communities in Chengguan district of Lanzhou since April 2011.The target population was middle-aged and elderly residents over 40 years old.Two follow-up surveys were carried out in 2014-2016 and 2021 successively,and 6543 people with complete follow-up data were finally included.The incidence and mortality rates of malignant tumors were calculated,as well as their age standardized rates with reference to the age composition of Segi's world standard population.Multivariate Cox regression analysis was used to screen the risk factors affecting the incidence and mortality of malignant tumors.Results After an average follow-up of 10.6 years,314 new cases of malignant tumors were found in middle-aged and elderly residents in Chengguan district of Lanzhou,with an incidence rate and age standardized incidence rate of 454.30/100 000 and 128.93/100 000,respectively.A total of 158 deaths were attributed to malignant tumors,with a mortality rate and age standardized rate of 228.41/100 000 and 607.9/100 000,respectively;The age standardized incidence rate and mortality rate of malignant tumors males were both higher than those females(P＜0.05).During the follow-up period,the age standardized incidence rate of malignant tumors in the general population showed an significant upward trend(P＜0.05),whereas the age standardized mortality rate gradually decreased after a brief increase(P＜0.05).Lung cancer,colorectal cancer,gastric cancer,and liver cancer were the main types of malignant tumors ranking in the top five in terms of incidence and mortality by gender.Multivariate Cox regression results indicate that male,age≥60 years old,college education level or above,smoking history,drinking history,having been hit by major stressful events,central obesity,hypertension,and coronary heart disease are risk factors for the onset or death of malignant tumors(HR＞1).Married,with family size≥4,frequent consumption of fresh fruit,frequent consumption of fresh vegetables,frequent consumption of grains and tubers are protective factors for the onset or death of malignant tumors(HR＜1).Conclusion The incidence of malignant tumors among middle-aged and elderly people in Chengguan district of Lanzhou from 2011 to 2021 showed an increasing trend,while the overall mortality was decreasing.Our study indicates early cancer screening in elderly populations,maintaining a healthy lifestyle and strengthening the management of chronic diseases are crucial for the prevention and treatment of malignant tumors.

Objective To investigate the molecular mechanism of verbascoside against acute lung injury(ALI)by network pharmacology and molecular docking methods,and to validate the findings experimentally.Methods The 2D structure of verbascoside was obtained from the Pubchem database.Active ingredient targets of verbascoside were acquired from Pharmmapper database and Swiss Target Prediction database.Active component targets of ALI were acquired from datebase such as Gene Cards,OMIM,and DisGeNET.Common targets between verbascoside and ALI were determined by overlapping these sets.PPI network for potential targets was constructed using String database and Cytoscape software.The intersection targets were imported into the DAVID database for enrichment analysis of GO biological processes,KEGG signaling pathway and the pathway target genes.Molecular docking between verbascoside and core targets was performed using Autodock vina software.The mRNA expression level of core genes was validated using real-time quantitative PCR(RT-qPCR),and the expression of related proteins was detected using Western blotting.Results A total of 150 target genes of verbascoside against ALI were screened,and the key targets of verbascoside against ALI mainly involve pathways such as Rap1 signaling pathway,PI3K-Akt signaling pathway and MAPK signaling pathway.Verbascoside docked well with the core target molecules.RT-qPCR results showed that,compared with the control group,the mRNA expression levels of HSP90AA1,ALB,TP53,TNF,INS,and HRAS were significantly decreased in cells after the effect of verbascoside(P<0.05);Western blotting indicated that,compared with the model group,verbascoside treatment significantly reduced the expression of p-Akt,p-p38,and p-ERK proteins(P<0.05).Conclusion Verbascoside could inhibit MAPK,Rap1 and PI3K/Akt signaling pathways to exert its anti-ALI effects.

Objective To investigate the main dietary patterns of children in urban areas of Maanshan City, and to explore the association between dietary patterns and subthreshold autism trait (SAT), attention-deficit/hyperactivity disorder (ADHD) symptoms and comorbid behaviors in 3-year-old children. Methods Based on the birth cohort of Maanshan Maternal and Infant Health from June 2015 to June 2016，regular physical examinations were conducted from 4 to 2 to 1, and follow-up was conducted until the age of 3. A semi-quantitative food frequency questionnaire was employed to assess dietary intakes. SAT and ADHD symptoms were assessed by Clancy autism behavior scale (CABS) and the 10-item Chinese version of the Conners Abbreviated Symptom Questionnaire (C-ASQ). Social-demographic information was also collected. Results The detection rates of SAT, ADHD symptoms, and comorbidity were 11.03%, 5.28%, and 2.71%, respectively. The older the father, the higher the mother's education level, and the higher the per capita monthly income of the family, the lower the SAT detection rate (P<0.05). The higher the father's educational level, the lower the detection rate of ADHD symptoms (P<0.05). The older the mother and the higher the education level, the lower the detection rate of comorbid behavior in their children (P <0.05). After adjusting for demographic influencing factors, the low intake level was used as a reference. The vegetarian type with moderate intake level was negatively correlated with SAT, while the processed food type with high intake level was positively correlated with SAT. The vegetarian type with high intake level was negatively correlated with ADHD symptoms, while the snack type with high intake level was positively correlated with ADHD symptoms. The vegetarian type with high intake level was negatively correlated with comorbidity. Conclusion Unhealthy dietary patterns are related to children's SAT and ADHD symptoms. Correcting children's unhealthy eating patterns may help reduce children's behavior problems.

Ankylosing spondylitis (AS) combined with lower cervical fracture is often categorized into unstable fracture, with a high incidence of neurological injury and a high rate of disability and morbidity. As factors such as shoulder occlusion may affect the accuracy of X-ray imaging diagnosis, it is often easily misdiagnosed at the primary diagnosis. Non-operative treatment has complications such as bone nonunion and the possibility of secondary neurological damage, while the timing, access and choice of surgical treatment are still controversial. Currently, there are no clinical practice guidelines for the treatment of AS combined with lower cervical fracture with or without dislocation. To this end, the Spinal Trauma Group of Orthopedics Branch of Chinese Medical Doctor Association organized experts to formulate Clinical guidelines for the treatment of ankylosing spondylitis combined with lower cervical fracture in adults ( version 2024) in accordance with the principles of evidence-based medicine, scientificity and practicality, in which 11 recommendations were put forward in terms of the diagnosis, imaging evaluation, typing and treatment, etc, to provide guidance for the diagnosis and treatment of AS combined with lower cervical fracture.
