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.

Objective: Data on syncopal donation-related vasovagal reaction (DRVR) collected from 74 blood centers between 2020 and 2023 was statistically analyzed to provide a reference for developing preventive strategies against syncopal DRVR. Methods: Data on blood donation adverse reactions and basic information of donors from 2020 to 2023 were collected through the information management system at monitoring sentinel sites. Statistical analysis was performed on the following aspects of syncopal DRVR: characteristics of donors who experienced syncope, reported incidence, triggers, duration, presence and occurrence time of syncope-related trauma, clinical management including outpatient and inpatient treatment, and severity grading. Results: From 2020 to 2023, 45 966 donation-related adverse reactions were recorded. Of these, 1 665 (3.72%) cases were syncopal DRVR. The incidence of syncopal DRVR decreased with age, being the highest in the 18-22 age group. Incidence was significantly higher in female donors than male donors, in first-time donors than repeat donors, and in university and individual donors than group donors (all P<0.05). There was no statistically significant difference among different blood donation locations (P>0.05). The top three triggers were tension, fatigue, and needle phobia or fear of blood. Among syncopal DRVR cases, 60.36% occurred during blood collection, 87.63% lasted for less than 60 seconds, and 5.05% were accompanied by trauma. Notably, 57.14% of these traumas occurred after donor had left the blood collection site. Syncope severity was graded based on required treatment: grade 1 (fully recovered without treatment, 95.50%); grade 2 (recovered after outpatient treatment, 4.02%); and grade 3 (recovered after inpatient treatment, 0.48%). Conclusion: By analyzing the data of syncopal DRVR cases, it is possible to provide a reference for formulating blood donor safety policies.

OBJECTIVE To develop a prediction model for durable clinical benefit （DCB） in patients with advanced esophageal squamous cell carcinoma （ESCC） receiving programmed death-1 （PD-1） inhibitor. METHODS The clinical data of patients with advanced ESCC who received PD-1 inhibitor in Jieyang People’s Hospital were retrospectively collected between January 2020 to December 2023. Predictors were screened by least absolute shrinkage and selection operator （Lasso） regression， and a multivariable Logistic regression model was developed to predict DCB. A nomogram was constructed based on the model. Internal validation of the prediction model was performed by using the Bootstrap method， and the model was evaluated by the receiver operating characteristic （ROC） curve， calibration curve， and decision curve analysis. RESULTS A total of 91 patients with advanced ESCC were included. The results of Lasso regression combined with Logistic regression analysis indicated that the baseline lymphocyte monocyte ratio （LMR） [odds ratio （OR）＝1.97， 95% confidence interval （CI）： 1.15-3.36， P＝0.013]， albumin （ALB） content （OR＝1.35， 95%CI： 1.13-1.60， P＜0.001）， body mass index （BMI） category 1 [normal vs. low： OR＝ 0.28， 95%CI （0.09-0.96）， P＝0.042]， BMI category 2 [overweight-obesity vs. low： OR＝0.08， 95%CI （0.01-0.59）， P＝0.013]， and treatment regimen [monotherapy vs. monotherapy combination therapy： OR＝0.07， 95%CI （0.01-0.50）， P＝0.008] were predictive factors for patients with advanced ESCC to achieve DCB when treated with PD-1 inhibitor. A prediction model was constructed based on the above indicators. Internal validation of the model using the Bootstrap method showed an area under the curve of 0.831 （95%CI： 0.746-0.904）， with specificity of 74.4% and sensitivity of 75.0%. The Hosmer-Lemeshow test yielded χ2＝ 9.930， P＝0.270， and the calibration curve slope was close to 1. The decision curve analysis demonstrated that the model exhibited good clinical utility within a threshold range of 0.1 to 1.0. CONCLUSIONS The prediction model based on baseline LMR， ALB content， BMI， and treatment regimen demonstrates robust predictive performance and clinical utility for assessing therapeutic efficacy of PD-1 inhibitor in the treatment of advanced ESCC.

Objective To summarize the best evidence for diaphragm rehabilitation in mechanically ven-tilated ICU patients with ventilator-associated diaphragm dysfunction based on evidence-based methods.Meth-ods A systematic search was conducted across guideline websites,professional associations,and Chinese/English databases for evidence regarding diaphragm rehabilitation in mechanically ventilated ICU patients.The search timeframe spanned from database inception to December 31,2024.Two researchers independently per-formed quality assessment and synthesized the evidence.Results Twenty articles were included:2 clinical de-cisions,1 guideline,2 evidence summaries,3 systematic reviews,7 randomized controlled trials(RCT),and 5 expert consensuses/opinions.Twenty-seven pieces of evidence were formed across 6 themes:rehabilitation team,rehabilitation assessment,rehabilitation interventions,outcome evaluation,precautions,and education/training.Conclusion This study summarizes the best evidence for diaphragm rehabilitation in ICU mechani-cally ventilated patients.Healthcare professionals should implement diaphragm rehabilitation by integrating this evidence with specific clinical contexts to improve patient outcomes and enhance nursing quality.

Objective To explore the necessity of placing an inferior vena cava filter(IVCF)during interventional therapy for acute lower extremity deep venous thrombosis(DVT)complicated with severe May-Thurner syndrome(MTS).Methods Patients with acute left lower extremity DVT complicated with severe MTS were retrospectively selected and divided into observation group(n=36)and control group(n=36)according to whether IVCF was implanted or not.Pulmonary embolism(PE)was evaluated using compu-ted tomography pulmonary angiography(CTPA).The improvement of the affected limb signs and the occurrence of PE symptoms during treatment were observed.The presence of trapped thrombus was checked during filter removal.The PE incidence,hospitaliza-tion costs,operation time,and hospital stay were compared between the two groups.Results Both groups had a higher thrombus clearance rate after interventional surgery,and the proportion of new small branch PE was lower without significant differences between the two groups(8.3%vs 5.6%,P=1.000).The signs of the affected limbs improved significantly,and no PE-related symptoms occurred during treatment.No obvious trapped thrombus was found when the filter was removed in the control group.Compared with the control group,the observation group had significantly reduced hospitalization costs and operation time(P<0.05).Conclusion For patients with acute lower extremity DVT complicated with severe MTS,omitting IVCF placement during interventional surgery does not increase the risk of PE and can reduce operation time and hospitalization costs.

Objective To explore the correlation between the pulmonary artery diameter(PAD),PAD/aortic diameter(AOD),right ventricular diameter(RVD),RVD/left ventricular diameter(LVD)measured on pulmonary artery CT angiography(CTPA)cross-sectional images and the degree of embolism,cardiac biomarkers in patients with medium-to-high risk acute pulmonary embolism(APE).Methods The clinical data of 53 patients with medium-to-high risk APE,who received interventional treatment at the Putian Municipal First Hospital of China From January 2021 to December 2023,were retrospectively analyzed.The PAD,PAD/AOD,RVD,and RVD/LVD were measured on CTPA cross-sectional images.The correlations of the above indexes with CT embolism index(CTEI),N terminal pro B type natriuretic peptide(NT-proBNP),and cardiac troponin Ⅰ(cTnⅠ)were analyzed.Results A weak-moderate positive correlation existed between PAD,RVD,RVD/LVD and CTEI(r=0.506,r=0.310,r=0.452 respectively,P＜0.001,P=0.024,P=0.001 respectively),while no correlation existed between PAD/AOD and CTEI(r=0.247,P=0.075).Compared with the NT-proBNP negative group,in the NT-proBNP positive group the values of PAD,PAD/AOD and RVD/LVD were higher(all P＜0.05),and there was no statistically significant difference in RVD value between the two groups(P＞0.05).A weak-moderate positive correlation existed between NT-proBNP and PAD,PAD/AOD,RVD,RVD/LVD(r=0.454,r=0.326,r=0.302,r=0.405 respectively,P=0.001,P=0.017,P=0.028,P=0.003 respectively).There were no statistically significant differences in PAD,PAD/AOD,RVD and RVD/LVD values between the cTnⅠ negative group and the cTnI positive group(all P＞0.05).No correlation existed between cTnⅠ and PAD,PAD/AOD,RVD,RVD/LVD(r=0.188,r=0.042,r=-0.021,r=0.139 respectively,and P=0.195,P=0.772,P=0.884,P=0.342 respectively).Conclusion CTPA cross-sectional quantitative indicators are helpful in evaluating the embolism degree of APE and right heart function,but it cannot be used to assess myocardial injury.

Objective:To evaluate the effect of prolonged cryopreservation duration of high-quality embryos on clinical outcomes.Methods:A retrospective cohort study was conducted, analyzing 8 988 frozen-thawed embryo transfer cycles performed from January 2016 to December 2023 at the Center for Reproductive Medicine, Chongqing Maternal and Child Healthcare Hospital where patients underwent endometrial preparation with artificial cycles and subsequent transfer of high-quality embryos. Embryos were divided into four groups according to the length of time they had been cryopreserved: ≤3-month group ( n=3 030), 4-6-month group ( n=3 193), 7-12-month group ( n=1 465), and >12-month group ( n=1 300). High-quality cleavage-stage embryos and blastocysts were selected according to the Istanbul Consensus and Gardner grading system. High-quality cleavage-stage embryos were defined as those graded ≤2, while high-quality blastocysts were defined as those graded ≥4BB. Generalized estimating equations were employed for multivariate analysis. Primary outcome indicator was clinical pregnancy rate, with secondary outcome indicators comprising live birth rate, miscarriage rate and preterm birth rate. Results:Significant intergroup differences were observed in baseline characteristics, including age, body mass index, anti-Müllerian hormone levels, fertilization method, endometrial thickness on transfer day, infertility etiology, infertility type, number of embryos transferred, embryo culture duration, number of eggs obtained, and preimplantation genetic testing (all P<0.05). Clinical pregnancy rates for the ≤3-month, 4-6-month, 7-12-month, and >12-month groups were 69.04% (2 092/3 030), 70.15% (2 240/3 193), 61.16% (896/1 465), and 57.69% (750/1 300), respectively, and live birth rates were 58.58% (1 775/3 030), 60.04% (1 917/3 193), 51.40% (753/1 465), and 47.00% (611/1 300), with significantly differences (all P<0.001). After adjusting for confounders via multivariate analysis, the 4-6-month group showed no statistically significant difference in clinical pregnancy rate or live birth rate compared with the ≤3-month group (clinical pregnancy: OR=0.982, 95% CI: 0.874-1.103, P=0.754; live birth: OR=0.989, 95% CI: 0.887-1.102, P=0.835). However, both the 7-12-month group (clinical pregnancy: OR=0.772, 95% CI: 0.671-0.888, P<0.001; live birth: OR=0.805, 95% CI: 0.704-0.921, P=0.002) and >12-month group (clinical pregnancy: OR=0.765, 95% CI: 0.662-0.885, P<0.001; live birth: OR=0.772, 95% CI: 0.671-0.888, P<0.001) exhibited significant decreases in clinical pregnancy rate and live birth rate. No significant differences were observed in miscarriage rate and preterm birth rate among the four groups (all P>0.05). Stratified by age, the results were consistent with the total population. Conclusion:The duration of high-quality embryo vitrification freezing exceeding 6 months is negatively correlated with clinical pregnancy rate and live birth rate, and cryostorage time should be considered as a relevant factor in embryo selection.
