ObjectiveTo observe the short-term and long-term efficacy of traditional Chinese medicine （TCM） surgical operations in treating mixed hemorrhoids. MethodsA multi-center retrospective cohort study was conducted， collecting clinical data from 17，831 mixed hemorrhoid surgery patients in 8 top-tier TCM hospitals in Jiangsu Province. Standardized and structured datasets were obtained through artificial intelligence models. Patients who underwent western surgical treatment were categorized into the western surgery group （11,646 cases）， and those receiving TCM surgical operations were categorized into the TCM surgery group （6185 cases）. Propensity score matching （1∶1 matching） was used to balance baseline data between groups. The primary outcome was the one-year recurrence rate， and secondary outcomes included the main symptoms （rectal bleeding， degree of prolapse） and secondary symptoms （anal distension， anal edema， wound secretion and exudation， anal stenosis， residual skin tags， perianal itching， and anal pain） measured on days 7， 28， and 60 after discharge. ResultsAfter matching， 2194 patients were included in each group. Symptom scores showed that at 28 days after discharge， the TCM surgical group had superior improvement in rectal bleeding ［OR=5.786， 95%CI （3.092，10.827）］， degree of prolapse ［OR=4.510， 95%CI （1.649，12.333）］， and anal edema ［OR=3.188， 95%CI （1.295，7.845）］ compared to the western surgical group. At 60 days post-discharge， the TCM group still showed advantages in improving rectal bleeding ［OR=5.237， 95%CI （1.077，25.464）］ and anal pain ［OR=11.697， 95%CI （1.186，115.336）］ （P＜0.05）. Long-term follow-up showed that the one-year recurrence rate in the TCM surgery group was 1.1% （8/726）， while that in the western surgery group was 2.3% （10/444）， with no statistically significant difference between the two groups （P＞0.05）. ConclusionBased on real-world data， TCM surgical treatment for mixed hemorrhoids shows significant short-term symptom improvement， particularly in terms of hemostasis， reducing swelling， and alleviating prolapse of anal masses.

ObjectiveTo explore the potential mechanism of Huoxue Xiaoyi Formula （活血消异方， HXF） in treating ovarian endometriosis （OEM） from the perspective of T follicular helper （Tfh） cells and the Janus kinase/signal transducer and activator of transcription （JAK/STAT） signaling pathway. MethodsForty-five female SD rats with normal estrous cycles were randomly divided into three groups， HXF group， model group， and normal group， with 15 rats in each group. A rat model of OEM was established by autologous endometrial tissue implantation. After successful modeling， the treatment group received HXF at 5.85 g/（kg·d） by gavage for 14 consecutive days. The model group and normal group received 1 mL/d of normal saline by gavage. RNA-sequencing data from human proliferative-phase endometriotic and normal endometrial tissues were downloaded from the GEO database. Transcriptomic sequencing was used to analyze gene expression in rat ovarian ectopic tissues and normal uterine tissues， and comparisons were made with human data to verify JAK/STAT pathway activation in proliferative-phase ectopic tissues. Immunohistochemistry was used to detect the positive expression of CXC chemokine receptor 5 （CXCR5） and interleukin-21 （IL-21） in rat ovarian ectopic and normal uterine tissues. Western Blotting was performed to detect the protein levels of IL-21， IL-21 receptor （IL-21R）， Janus kinase 1 （JAK1）， signal transducer and activator of transcription 6 （STAT6）， and B-cell lymphoma 2 （Bcl-2）. Tfh cell infiltration was analyzed using immune cell infiltration methods. ResultsGene set enrichment analysis showed that the JAK/STAT pathway was significantly activated in human proliferative-phase endometriotic tissues compared to normal endometrial tissues. Similarly， the JAK/STAT pathway was markedly activated in rat ovarian ectopic tissues in the model group compared to the normal group， but suppressed in the HXF group compared to the model group. Compared with normal uterine tissues， ovarian ectopic tissues in the model group showed increased Tfh cell infiltration scores， higher CXCR5 and IL-21 expression， and elevated levels of IL-21， IL-21R， JAK1， STAT6， and Bcl-2 proteins. Compared with the model group， HXF group showed reduced CXCR5 and IL-21 expression and decreased protein levels of IL-21， IL-21R， JAK1， STAT6， and Bcl-2. ConclusionHXF may suppress activation of the JAK/STAT signaling pathway in ovarian endometriotic tissues by inhibiting IL-21 secretion from Tfh cells.

Objective To understand the application effect of early screening scale and behavioral intervention effect in children with autism spectrum disorder (ASD). Methods A total of 348 children with suspected ASD were selected and evaluated using the Modified Checklist for Autism in Toddlers (M-CHAT) and Autism Behavior Checklist (ABC). The evaluation results were compared with those from the Diagnostic and Statistical Manual of Mental Disorders (DSM-V). Children enrolled were given Early start Denver model (ESDM) intervention. The evaluation results of Gesell Developmental Scale and Autism Treatment Evaluation Checklist (ATEC) scores were compared before and after intervention. Results The sensitivity, specificity, accuracy and Kappa value of M-CHAT for evaluating ASD in children aged 1-3 years were 89.53%, 90.70%, 89.92% and 0.78. The corresponding values of ABC were 78.49%, 81.40%, 79.46% and 0.56. The sensitivity, specificity, accuracy and Kappa value of M-CHAT for evaluating children aged >3-6 years were 87.30%, 77.78%, 84.44% and 0.64. The corresponding values of ABC were 85.71%, 77.78%, 83.33% and 0.62. The sensitivity and accuracy of M-CHAT were higher than ABC for evaluating ASD in children aged 1-3 years (P<0.05). There were no significant differences in sensitivity, specificity and accuracy between M-CHAT and ABC for evaluating ASD in children aged 3-6 years (P>0.05). After intervention, development quotients (DQ) of personal-social aspects, adaptability, language, gross motor, and fine motor of children with ASD were higher than those before intervention (P<0.05). ATEC scores for language, behavior, sensation, and social contact of children with ASD were lower than those before intervention (P<0.05). Conclusion M-CHAT and ABC both can be used for early screening of ASD in children, especially M-CHAT. Early behavioral intervention can effectively improve the condition and developmental level of children with ASD.

ObjectiveTo analyze the epidemiological characteristics of long COVID and to investigate its main influencing factors by examining individuals infected with SARS-CoV-2 between March and June 2022 in two communities in Shanghai, to lay the foundation for further research on the mechanism and clinical treatment of long COVID, and to provide the basis for the development of inexpensive, convenient, and feasible prevention and intervention strategies. MethodsA cross-sectional study was conducted, enrolling 6 410 individuals infected with SARS-CoV-2. Data were collected through a questionnaire survey. The incidence and common symptoms of long COVID were analyzed, along with their associations with demographic characteristics, medical history, and behavioral factors. A logistic regression model was used to identify the major factors associated with the development of long COVID symptoms. ResultsThe overall incidence rate of long COVID among the study population was 13.9%. The most commonly reported symptoms included fatigue (65.1%), attention disorders (23.1%), and cough (16.9%). The analysis showed that having underlying chronic diseases (OR=2.580, 95%CI: 2.165‒3.074), a history of allergies (OR=1.418, 95%CI: 1.003‒1.971), current smoking (OR=1.461, 95%CI: 1.013‒2.079), ever smoking (OR=2.462, 95%CI: 1.687‒3.551), a greater number of symptoms during the acute phase [1 symptom (OR=1.778, 95%CI: 1.459‒2.162), 2 symptoms (OR=2.749, 95%CI: 2.209‒3.409), ≥3 symptoms (OR=7.792, 95%CI: 6.333‒9.593)] and aggravated symptoms during the acute phase (OR=1.082, 95%CI: 1.070‒1.094) were factors associated with a higher risk of developing long COVID symptoms. Additionally, individuals who had consumed alcohol in the past year (OR=1.914, 95%CI: 1.344‒2.684) were more prone to objective long COVID symptoms. Among individuals under 50 years of age, females (OR=1.427, 95%CI: 1.052‒1.943) were more likely to develop objective long COVID symptoms. ConclusionThis study has identified the diversity of long COVID symptoms, which involve multiple organs and systems, including fatigue, attention disorders, cough, and joint pain. It has also revealed associations between long COVID and various demographic factors (e.g., age, gender), personal medical history (e.g., underlying chronic diseases, history of allergies), acute-phase characteristics (e.g., number and severity of symptoms), and behavioral factors (e.g., smoking, alcohol consumption). These findings highlight the need for further research and ongoing surveillance of long COVID and may inform the development of more targeted health management strategies for specific populations.

OBJECTIVE To evaluate the safety， efficacy， and cost-effectiveness of sodium-glucose co-transporter 2 （SGLT-2） inhibitors for treating type 2 diabetes mellitus （T2DM）. METHODS Retrieved databases such as PubMed， Cochrane Library， Embase， CNKI， as well as relevant health technology assessment （HTA） official websites， HTA reports， systematic review/meta- analysis and pharmacoeconomic studies about SGLT-2 inhibitors （including 12 types such as canagliflozin， dapagliflozin， and empagliflozin） in the treatment of T2DM were collected from the inception to January 28， 2025. After literature screening data extraction and quality assessment， a descriptive analysis was conducted on the results of the included studies. RESULTS A total of 38 articles were included， comprising 30 systematic reviews/meta-analyses， 4 pharmacoeconomic studies， and 4 HTA reports. In terms of effectiveness， most research results showed that canagliflozin was effective in controlling blood glucose， reducing body weight， and lowering blood pressure compared to other SGLT-2 inhibitors， while empagliflozin could effectively reduce all-cause mortality. In terms of safety， compared with other SGLT-2 inhibitors， empagliflozin has a lower overall adverse event rate and cardiovascular death risk， canagliflozin presented a higher risk of hypoglycemia， and dapagliflozin had a higher risk of urinary tract infections. In terms of economics， empagliflozin possessed greater economic advantages over both dapagliflozin and canagliflozin， while canagliflozin offered more benefits than dapagliflozin. CONCLUSIONS The selection of SGLT-2 inhibitors for the treatment of T2DM should be individualized. Canagliflozin is recommended for patients with high cardiovascular risk. Empagliflozin boasts the best overall safety profile. Dapagliflozin should be used with caution in patients at high risk of urinary tract infections. Based on foreign economic evidence， empagliflozin has economic advantages. In the future， drug economic studies under the Chinese health system need to be conducted.

OBJECTIVE To evaluate the long-term cost-effectiveness of canagliflozin or semaglutide in patients with type 2 diabetes mellitus（T2DM）poorly controlled with metformin. METHODS Based on the perspective of China’s health system， a Markov model was used to calculate the long-term costs and utilities of canagliflozin or semaglutide combined with metformin for T2DM patients in China for 30 years based on the data from SUSTAIN 8 study. The incremental cost-effectiveness ratio（ICER） and incremental net monetary benefit （INMB） were calculated using one time the 2024 per capita gross domestic product（GDP） as the willingness-to-pay（WTP） threshold. One-way sensitivity analysis， probability sensitivity analysis and scenario analysis were conducted to confirm the stability of the conclusions. RESULTS Compared with canagliflozin + metformin， ICER of semaglutide combined with metformin was 260 485.67 yuan/quality-adjusted life year （QALY），which was higher than the WTP threshold set in this study （95 749 yuan/QALY），and the corresponding INMB was －61 576.24 yuan，indicating that the canagliflozin + metformin regimen was more cost-effective. The cost of diabetes without complications treatment in the semaglutide + metformin group had the greatest influence on INMB，but changes in parameters within the selected range did not drive decision reversal. With the increasing of WTP threshold，the economic acceptability of semaglutide + metformin regimen increased. Under the current WTP threshold，the annual cost of semaglutide should be reduced by 42.95% to make the semaglutide + metformin regimen more cost- effective. CONCLUSIONS From the perspective of China’s health system， canagliflozin + metformin is more cost-effective than semaglutide + metformin for T2DM patients yueru. with poor glycemic control with metformin alone.

[Purpose]To analyze the cost-effectiveness and cost-utility conducted on the lung can-cer screening project in urban areas of Anhui Province,and to provide suggestions for the formu-lation of lung cancer screening policies in Anhui Province.[Methods]A Markov decision model for low-dose computed tomography(LDCT)lung cancer screening intervention was established based on on-site survey data and literature data.The development of the population under different interventions was simulated,using saved life years(LYS)and quality-adjusted life years(QALY)as effectiveness indicators,to conduct cost-effectiveness and cost-utility analyses of different screening strategies.Cost data were discounted at a 3％discount rate.[Results]The screening schemes of once a year,once every two years,once every three years,and once every five years all meet the cost-effectiveness principle for saving one LYS or QALY.Among them,the best screening strategy in terms of cost-effectiveness and cost-utility was the LDCT lung cancer screening strategy once every two years,with costs of 72 441.54 CNY and 71 050.24 CNY,respectively.[Conclusion]The LDCT lung cancer screening program demonstrates good cost-effectiveness,with strategies of dif-ferent screening frequencies being viable options.The optimal screening strategy is screening once every two years.

Objective:To investigate predictive value of dynamic electrocardiogram heart rate variability(HRV)combined with three-dimensional spot tracking echocardiography(3D-STE)for postoperatively major adverse cardiovascular events(MACE)in patients with coronary heart disease(CHD).Methods:The clinical data of 80 CHD patients,who underwent percutaneous coronary intervention(PCI)treatment at Beijing Rehabilitation Hospital affiliated with Capital Medical University from January 2022 to December 2023,were retrospectively collected.All patients underwent dynamic electrocardiogram HRV and 3D-STE examination before surgery,and 1-year follow-up.The condition of occurring MACE during the follow-up period was analyzed as statistical method,and the patients were divided into occurrence group(21 cases)and non-occurrence group(59 cases).The relevant parameters of dynamic electrocardiogram HRV and 3D-STE examination of occurring MACE of CHD patients between two groups were compared,and the predictive value of dynamic electrocardiogram HRV combined with 3D-STE examination for postoperative MACE of CHD patients was analyzed.Results:In 80 CHD patients,21 cases occurred postoperative MACE,with an incidence rate of 26.25%.The standard deviation of the average NN intervals(SDANN)(65.26±9.65)ms of 5-minute sinus,the standard deviation of normal-to-normal intervals index(SDNN Index)(40.15±6.36)ms of 5-minute in continuous 24 hours,the root mean square of successive differences(r-MSSD)(36.86±4.55)ms between the normal adjacent cardiac cycles,the left atrial emptying fraction(LAEF)(40.25±4.53)%,and the left atrial storage phase strain(LASr)(15.24±3.62)%in CHD patients with MACE were lower than those without MACE[(87.45±10.22)ms,(52.45±7.85)ms,(46.54±6.25)ms,(48.54±6.33)ms,(19.99±4.55)%],and the left atrial pre-contraction volume(LAVp)(42.51±3.65)ml was higher than that(35.18±2.99)mL in patients without MACE,with statistically significant differences(t=8.666,6.457,6.499,9.093,5.510,4.317,P<0.05).Logistic regression analysis showed that SDANN,SDNN Index,r-MSSD,LAVp,LAEF,LASr were correlations with the occurrence of postoperative MACE in CHD patients(OR=0.756,0.772,0.694,2.481,0.721,0.739,P<0.05).The receiver operating characteristics(ROC)curves indicated that the area under curve(AUC)values of SDANN,SDNN Index,r-MSSD,LAVp,LAEF and LASr were all greater than 0.70 in predicting postoperative MACE in CHD patients,which indicated all of them had predictive value,and the predictive value of the combined detection was higher.Conclusion:Dynamic electrocardiogram HRV and 3D-STE parameters have a certain predictive value for the occurrence of postoperative MACE in CHD patients,and the predictive value of the combined detection for the them are higher.Therefore,dynamic electrocardiogram HRV and 3D-STE parameters can be used as one of the important reference schemes of assessing postoperative MACE of patients.
