With the progress of medical insurance reform,the refinement of medical insurance management in pub-lic hospitals still fails to meet the actual demands for medical insurance work.Based on the existing problems of medical insurance management,it emphasizes the necessity of the refined management of medical insurance.By integrating be-havioral economics theory,it divides the refined management of medical insurance into five distinct stages:develop-ment planning,process-oriented platform,organizational framework,staff training programs and regulatory supervi-sion.The behavioral logic of the refined management of medical insurance in public hospitals is analyzed.Building on this analysis,the relevant key insights are summarized to provide a reference for promoting the public welfare-oriented reform of public hospitals and realizing the high-quality development of public hospitals.

Objective:To analyze the associated factors and cumulative effects of cardiometabolic multimorbidity (CMM) among residents in southern Xinjiang.Methods:A stratified random cluster sampling method was used to conduct questionnaire surveys, physical examinations and laboratory tests among the personnel of the 51st Brigade, 3rd Division, Xinjiang, in 2016. The multivariate logistic regression, multivariate linear regression, restricted cubic spline, and network analysis methods were used to study the association of lifestyle (smoking, alcohol consumption and physical activity), socioeconomic (occupation, education and marital status) and clinical factors (waist circumference, body mass index and family history) with CMM.Results:A total of 12 773 study subjects were included. The prevalence of cardiovascular metabolic diseases among residents in southern Xinjiang was 52.49%. Specifically, the prevalence rates of dyslipidemia, hypertension, coronary heart disease, diabetes, and stroke were 31.14%, 29.95%, 6.78%, 6.26%, and 2.47%, respectively, and the prevalence of CMM was 19.06%. Multivariate logistic regression analysis revealed that the associations between clinical and socioeconomic factors and CMM significantly increased with higher scores. Specifically, the OR rose from 1.75 (clinical factors) and 1.07 (socioeconomic factors) on a score of 1 to 4.41 and 1.93 on a score of 3, respectively. The association between lifestyle factors and CMM was only observed at higher scores ( OR=1.26, 95% CI:1.07~1.62). The trend test using the scores of each group as continuous variables in the model showed that the risk of disease increased with the accumulation of clinical, socioeconomic and lifestyle factors (all P<0.05). Restricted cubic spline analysis demonstrated a non-linear relationship between the total number of associated factors and CMM ( Poverall<0.05 and Pnon-linear<0.05). Network analysis identified hypertension (strength=0.42) as the “core node” among the five diseases. When analyzing the three types of influencing factors, hypertension (strength=0.68), dyslipidemia (strength=0.47), coronary heart disease (strength=0.37), and clinical factors (strength=0.53) emerged as “core nodes”. In the network of nine associated factors, abnormal waist circumference and BMI (strength=0.90 and 0.84) were identified as “key factors”, while hypertension (strength=0.68) and dyslipidemia (strength=0.52) were identified as “key diseases”. Conclusion:The prevalence of CMM among residents in southern Xinjiang is high, and there is a cumulative effect of multiple factors. Hypertension and dyslipidemia are key diseases in the multimorbidity network, while abnormal BMI and waist circumference are key associated factors.

Objective:To prepare ((2-(2-chlorophenyl)-3-(4-((2- 18F-fluoroethyl)oxy)phenyl)-5, 6, 7, 8-tetrahydrooxepino[3, 2-c]pyrazol-8-yl)amino)methanoic acid methyl ester ( 18F-JR-1001) and evaluate its binding affinity to the cannabinoid type 1 receptor (CB1R). Methods:18F-JR-1001 was synthesized using an integrated automated synthesis module, and its radiochemical yield (RCY) and molar activity were determined. Cell-specific uptake, lipid-water partition coefficient (log P), competitive binding assays, and in vitro stability tests were performed. Rimonabant-fed rat models (blocking group) with pre-occupied CB1R were established. Radioautography and microPET/CT imaging were conducted on both the blocking group and normal Sprague-Dawley (SD) rats to evaluate the brain uptake of 18F-JR-1001 and its blood-brain barrier (BBB) penetration capability. Results:The RCY of the synthetic 18F-JR-1001 after decay correction was (32.5±9.2)% ( n=10), with the molar activity of (194.6±67.3)GBq/μmol. Cell experiments demonstrated that 18F-JR-1001 exhibited specificity for CB1R, with log P of 3.40±0.11 ( n=3) and half-maximal inhibitory concentration of 0.975nmol/L. Within 3h at 37℃, the radiochemical purity of 18F-JR-1001 in physiological saline and blood remained above 92%, with no significant radioactive by-product peaks observed. Radioautography showed that the whole brain uptake of 18F-JR-1001 in the blocking group was 65.6% of that in normal SD rats. MicroPET/CT imaging showed that the mean whole brain uptake of 18F-JR-1001 in the blocking group was 0.4706, which was lower than that in normal SD rats (1.0561). Additionally, continuous scanning for 60min demonstrated that 18F-JR-1001 exhibited good BBB penetration capability. Conclusion:The synthesized 18F-JR-1001 meets the requirements of production and application, and is proved the potential as a CB1R-targeted tracer in the in vitro experiments, microPET/CT imaging and radioautography.

Objective:To develop and validate a novel PET tracer, N-cyclohexyl-4-((2, 4-dichlorophenyl)(4-(fluoro- 18F)phenyl)methyl)piperazine-1-carboxamide ( 18F-SQKJ-2), targeting cannabinoid type 1 (CB1) receptors for diagnosing psychiatric disorders associated with fear memory. Methods:18F-SQKJ-2 was prepared using a nucleophilic substitution radiochemical synthesis method. For the CB1 receptor blocking experiment, 7 ICR mice were divided into blocking group ( n=4; rimonabant for blocking treatment) and control group 1 ( n=3; no rimonabant blocking treatment). The affinity and specificity of 18F-SQKJ-2 for CB1 receptors were analyzed based on the differences in 18F-SQKJ-2 uptake (percentage injected dose per gram of tissue, %ID/g) by various organs between two groups. The metabolic stability of 18F-SQKJ-2 in vitro was studied using animal tissue homogenates. Ten C57 mice were used to establish fear memory mouse models (fear group, n=6; control group 2, n=4), and the percentage of freezing time was compared between 2 groups. MicroPET scans were used to detect the intracranial distribution of 18F-SQKJ-2, and the relative uptake in each brain region compared to total brain uptake was calculated. Statistical analysis was conducted to compare the differences in CB1 receptor relative total brain uptake in fear-related brain regions between 2 groups. Independent-sample t test and Mann-Whitney U test were used to analyze the data. Results:18F-SQKJ-2 was successfully synthesized with a radiochemical purity ≥98.0% and a corrected radioactive yield of (12.3±6.0)%( n=4). In vitro metabolic stability experiments showed that 18F-SQKJ-2 was basically stable in the liver, blood, and brain within 60min. The CB1 receptor blocking experiment demonstrated that the uptake of 18F-SQKJ-2 in the brains of mice in blocking group was significantly lower than that in control group 1 ((0.95±0.28) vs (3.44±1.16) %ID/g; t=-3.57, P=0.023). The percentage of freezing time in fear group was significantly higher than that in control group 2 (43.28%(39.46%, 52.93%) vs 2.74%(1.52%, 4.85%); Z=-2.45, P=0.010). 18F-SQKJ-2 microPET imaging showed that the uptake of 18F-SQKJ-2 in the cerebral cortex of mice in fear group was significantly increased compared with that in control group 2 ((5.83±0.47)% vs (5.00±0.52)%; t=2.42, P=0.046). Conclusion:18F-SQKJ-2 is successfully prepared with acceptable radiochemical purity and metabolic stability, demonstrating potential for visualizing and quantifying fear memory.

This consensus was developed by the Orthodontic Society of the Chinese Stomatological Association to provide a systematic, scientific, and practical guideline for informed consent in orthodontic care. Orthodontic treatment is typically lengthy, highly individualized, and involves multiple factors such as growth and development, occlusal function, and facial esthetics. Rapid technological advances and diverse risk profiles make the traditional reliance on orthodontist experience or institutional templates insufficient to ensure patients′ full understanding and autonomous decision-making. To address this, the expert panel conducted extensive reviews of domestic and international guidelines, analyzed representative dispute cases, and performed multicenter patient-clinician surveys. Using a multi-round Delphi method, the group established a standardized informed consent framework covering the initial consultation, treatment, and retention phases. The consensus emphasizes that informed consent is not only a fundamental legal and ethical requirement but also a key step in building trust, improving patient compliance, and enhancing treatment satisfaction. Orthodontists should clearly and comprehensively explain treatment plans, potential risks, uncertainties, and associated costs, while respecting the autonomy of patients or guardians, and maintain continuous communication and dynamic evaluation throughout the treatment process. The release of this consensus provides unified and authoritative guidance for clinical orthodontics, helping to standardize informed consent, enhance its transparency, safeguard patient rights, reduce medical risks, and promote high-quality, sustainable development of orthodontic practice.

The prevalence of Class III malocclusion varies among different countries and regions. The populations from Southeast Asian countries (Chinese and Malaysian) showed the highest prevalence rate of 15.8%, which can seriously affect oral function, facial appearance, and mental health. As anterior crossbite tends to worsen with growth, early orthodontic treatment can harness growth potential to normalize maxillofacial development or reduce skeletal malformation severity, thereby reducing the difficulty and shortening the treatment cycle of later-stage treatment. This is beneficial for the physical and mental growth of children. Therefore, early orthodontic treatment for Class III malocclusion is particularly important. Determining the optimal timing for early orthodontic treatment requires a comprehensive assessment of clinical manifestations, dental age, and skeletal age, and can lead to better results with less effort. Currently, standardized treatment guidelines for early orthodontic treatment of Class III malocclusion are lacking. This review provides a comprehensive summary of the etiology, clinical manifestations, classification, and early orthodontic techniques for Class III malocclusion, along with systematic discussions on selecting early treatment plans. The purpose of this expert consensus is to standardize clinical practices and improve the treatment outcomes of Class III malocclusion through early orthodontic treatment.

OBJECTIVE To explore optimization pathways for the drug traceability code management model in outpatient pharmacy workflows， providing practical evidence for enhancing the efficiency of pharmaceutical service. METHODS Taking the outpatient pharmacy of the First Affiliated Hospital of Sun Yat-sen University as the research subject， a comprehensive drug traceability system was established through three key interventions： upgrading the information system architecture [including integration of the hospital information system （HIS） with the traceability platform]， workflow optimization （reorganizing the inventory-dispensing-verification tripartite process）， and designing a dual-mode traceability data collection mechanism （primary data capture at dispensing stations and supplementary capture at verification stations）. Operational efficiency differences before and after implementation were analyzed using the medical insurance data and service timeliness metrics in September 2024. RESULTS After the implementation of drug traceability code management， in terms of data collection: Mode Ⅰ （verification-stage capture） uploaded 26 144 records， while Mode Ⅲ （inventory-as-sales capture） uploaded 443 061 records， totaling 469 205 entries； in terms of time efficiency： average drug dispensing time increased from 28.74 s to 43.37 s （enhanced by 51%）. Through dynamic staffing adjustments， patient wait time only extended from 8.04 min to 8.67 min （enhanced by 8%）. CONCLUSIONS Drug traceability code management can be effectively implemented via a “system reconstruction-process reengineering-human-machine collaboration” trinity strategy， leveraging informatization （e.g.， dual-mode data capture） to offset manual operation delays， which validates the feasibility of balancing national traceability demands with service efficiency in outpatient pharmacies.

Aim To investigate the related influencing factors of major adverse cardiovascular events(MACE)in coronary heart disease(CHD)patients with type 2 diabetes mellitus(T2DM)based on prognostic nutritional index(PNI),and to construct a prediction model.Methods The clinical data of 391 patients with CHD combined with T2DM who were hospitalised in the Department of Cardiovascular Medicine of Hebei Provincial People's Hospital from Janu-ary 2022 to January 2023 were collected and followed up for 1 year,and were divided into the MACE group(n=99)and the non-MACE group(n=292)according to the presence or absence of the occurrence of MACE,and were divided into the training set(n=273)and the validation set(n=118)in a ratio of 7:3 by using the computer-generated random number method,and the patients in the training set were divided into the MACE(n=67)group and the non-MACE group(n=206)according to whether they had MACE or not.Lasso regression was used to screen the relevant influencing factors and to construct the prediction model of the column-line diagram,and the prediction model was validated by plotting receiv-er operating characteristic(ROC)curve,calibration curve,decision curve analysis(DCA),and clinical impact curve(CIC).Results Lasso regression showed that the use of angiotensin receptor neprilysin inhibitor(ARNI),fasting blood glucose(FBG),C-reactive protein(CRP),platelet to lymphocyte ratio(PLR),lipoprotein(a)(Lp(a)),and PNI were the predictors of the occurrence of MACE in patients with CHD combined with T2DM.A column-line graph pre-diction model was constructed and validated based on the above predictors,and the area under the ROC curve(AUC)was 0.838(95％CI:0.778～0.898)in the training set and0.872(95％CI:0.803～0.942)in the validation set,with a good discriminatory degree of the model,and the C-values of the calibration curves in the training set and the validation set were 0.838 and 0.872,respectively,with good fit.The results of the decision curve analysis and the clinical impact curve showed that the column-line graph prediction model had a higher net yield of MACE in patients with CHD combined with T2DM,with high clinical utility.Conclusion PNI is an influential factor in the occurrence of MACE in patients with CHD combined with T2DM,and the column-line graphical model constructed on the basis of predictors such as PNI is con-venient for clinical use and has high predictive value in predicting the occurrence of MACE in patients with CHD combined with T2DM.

Objective:To explore the relationship between impulsivity traits,anxiety,and symptoms of eating disorders,with a focus on the mediating effect of anxiety between impulsivity and eating disorder symptoms.Me-thods:A total of 244 patients with eating disorders meeting the DSM-5 diagnostic criteria for anorexia nervosa(AN)and bulimia nervosa(BN)were enrolled,and the Eating Disorder Inventory-1(EDI-1),Barratt Impulsive-ness Scale(BIS-11),and the State Anxiety Inventory(SAI)were assessed.Mediation role analysis was performed by SPSS macro PROCESS program.Results:There was a significant positive correlation between the total score of BIS-11,SAI and EDI-1 in AN and BN patients(AN,r=0.56,0.63,0.72;P＜0.001.BN,r=0.51,0.31,0.56;P＜0.001 or P＜0.01).The total score of SAI played a mediating effect between the total score of BIS-11 and the total score of EDI-1,but the total score of SAI played a partial mediating effect(effect ratio was 46.9％)in patients with AN,and the total score of SAI played a full mediating effect in patients with BN.Conclusion:Impulsive trait and anxiety may be positive predictors of eating disorder symptoms.Anxiety mediates the relationship between impul-sivity trait and eating disorder symptoms,with a partial mediating effect in patients with AN and a full mediating effect in patients with BN.
