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: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.

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.

AIM:To evaluate the safety and toler-ability of single dose oral BTK inhibitor YZJ-3058 tablets under fasting conditions in healthy adults,as well as the pharmacokinetic and pharmacologi-cal characteristics of YZJ-3058 and its metabolites.METHODS:A total of 22 healthy subjects were en-rolled in this experiment and administered a single dose orally.They were divided into three groups:50 mg,100 mg,and 200 mg.Among them,2 sub-jects were enrolled in the 50 mg dose group,and 10 subjects were enrolled in the 100 mg and 200 mg dose groups,respectively.RESULTS:In healthy subjects,YZJ-3058 tablets were administered orally on an empty stomach at doses of 50,100,and 200 mg,with a median Tmax of 1.25 to 2.00 hours and an average Cmax of 62.85,89.44,and 99.20 ng/mL,re-spectively.The average AUC0-t was 183.87,297.72,and 453.98 h·ng-1·mL,respectively.The average AUC0-∞ was 189.30,321.33,and 551.44 h·ng-1·mL,and the median t1/2 was 1.16,5.06,and 7.97 hours,respectively.After a single oral administration of 50,100,and 200 mg YZJ-3058 tablets,the highest target occupancy rate was achieved at 4 hours.The average BTK occupancy rates at 24 hours after ad-ministration were 88.95％,96.73％,and 99.24％,re-spectively.The average BTK occupancy rates at 48 hours after administration were 75.65％,89.80％,and 96.68％,respectively.No serious adverse events or adverse events leading to withdrawal oc-curred,and all subjects had good tolerability.CON-CLUSION:YZJ-3058 tablets have good safety and tolerability for single oral administration on an empty stomach in healthy subjects within the dose range of 50-200 mg.Cmax and AUC increase with dose,with fast absorption and saturation.The ter-minal elimination rate gradually slows down with dose increase,and it has a significant and sus-tained occupying effect on BTK targets.

Objective:To describe the prevalence of anxiety disorders and its distribution in Inner Mongolia Autonomous Region,and to explore the relevant factors of anxiety disorders.Methods:From June 2019 to Decem-ber 2019,representative multi-stage disproportionate stratified sampling procedure was used to sample in residents aged 18 and over in the Inner Mongolia Autonomous Region.All respondents were face-to-face interviewed by trained interviewers.Composite International Diagnostic Interview-3.0(CIDI-3.0)was used to diagnose anxiety disorders according to the criteria and definition of the Diagnostic and Statistical Manual of Mental Disorders,Fourth Edition(DSM-Ⅳ).Chi-square test and multivariate logistic regression analysis were used for statistical anal-ysis.Results:Totally 12 315 people were interviewed in the survey.The weighted 12-mouth prevalence rate of any anxiety disorder was 4.64％,and the lifetime prevalence rate was 6.25％.The weighted 12-month prevalence rate of anxiety disorders was higher in female than that in male(5.38％vs.3.92％).The rate was higher in rural resi-dents than that in urban residents(5.67％vs.3.95％).The rate was higher in people with chronic diseases than that in people without chronic diseases(6.81％vs.2.29％).Logistic regression analysis showed that unmarried(OR=2.32,95％CI:1.31-4.10),separated/divorced(OR=2.49,95％CI:1.33-4.67),in debt(OR=1.55,95％CI:1.04-2.32),chronic disease(OR=2.22,95％CI:1.39-3.53),family history of anxiety disorders(OR=12.05,95％CI:8.78-16.53),poor sleep(OR=2.64,95％CI:1.97-3.54)were risk factors of occurrence of anxiety disorders,while junior high school(OR=0.65,95％CI:0.44-0.96)was protective factor of anxiety disor-ders.Conclusion:Adults with chronic diseases,poor sleep,unmarried or separated/divorced,family history of anxi-ety disorders,and financial debt are at higher risk groups of anxiety disorder in Inner Mongolia Autonomous Re-gion.

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 evaluate the short-term and long-term outcomes of patients with locally advanced low rectal cancer who achieved clinical complete response (cCR) or near-clinical complete response (near-cCR) after neoadjuvant chemoradiotherapy (nCRT) and then underwent local excision.Methods:This was a descriptive case series study. Clinical data of patients with low rectal cancer who received neoadjuvant therapy, achieved cCR or near-cCR, underwent local excision, and had complete postoperative follow-up data were retrospectively analyzed. The study period was from May, 2015 to October, 2024, and the patients were treated at Fujian Medical University Union Hospital. Indications for local excision in this study were as follows: pathologically confirmed rectal adenocarcinoma, with the lower edge of the tumor ≤ 6 cm from the anal verge; maximum diameter of the lesion ≤ 2 cm after nCRT; no regional lymph node metastasis detected by transrectal endoscopic ultrasound (ERUS), pelvic magnetic resonance imaging (MRI), or positron emission tomography-computed tomography (PET-CT) after nCRT; MRI showing fibrosis of the primary lesion with a small amount of high signal on diffusion-weighted imaging (DWI), consistent with ymrT0-1 stage; serum carcinoembryonic antigen level within the normal range (< 5 μg/L) after nCRT; complicated with severe underlying diseases such as cardiovascular and cerebrovascular diseases and assessed as unable to tolerate radical surgery through comprehensive evaluation; and signed informed consent for local excision. The contraindications were: colonoscopic pathology indicating poorly differentiated adenocarcinoma or signet ring cell carcinoma; suspected lateral lymph node metastasis before neoadjuvant therapy; patients with residual lesions exceeding 3 cm in range after treatment. A total of 153 patients were included in this study, including 84 males and 69 females. The median age was 62 years, and the median distance from the tumor to the anal verge after neoadjuvant therapy was 4.0 cm. The short-term efficacy indicators of this study included postoperative complications of local excision and postoperative pathological results, and the long-term efficacy indicators included oncological prognosis (3-year cumulative local recurrence rate, 3-year cumulative distant metastasis rate, 3-year progression-free survival, and 3-year overall survival) and anal function at 1 year after surgery evaluated using the Low Anterior Resection Syndrome (LARS) scale where the total score is 42 points such that 0-20 points indicate no LARS, 21-29 points indicate mild LARS, and 30-42 points indicate severe LARS.Results:Postoperative pathology showed 122 cases (79.7%) of ypT0 stage, 10 cases (6.5%) of ypT1 stage, 18 cases (11.8%) of ypT2 stage, and 3 cases (2.0%) of ypT3 stage. The incidence of surgery-related complications was 42.5% (65/153), and the main complications included perianal pain (39.9%, 61/153), intestinal wall incision dehiscence (21.6%, 33/153), and intestinal wall incision infection (18.3%, 28/153). The proportion of patients who received hypofractionated radiotherapy before surgery and developed intestinal wall incision dehiscence was 65.2% (15/23), which was higher than that in the conventional long-course (13.6%, 16/118) and short-course radiotherapy groups (16.7%,2/12) (χ 2=30.55, P<0.001); of the 20 patients who received additional immunotherapy before surgery, 13 developed intestinal wall incision dehiscence was 65.0%, which was higher than that in the group without additional immunotherapy [15.0%(20/133),χ 2=25.66, P<0.001]. The median follow-up time of the entire group was 35.4 months. During the follow-up period, there were 9 cases of postoperative local recurrence, with a 3-year cumulative local recurrence rate of 7.9% and 5 cases of distant metastasis, with a 3-year cumulative distant metastasis rate of 5.0%. The 3-year progression-free survival rate was 89.0%, and the 3-year overall survival rate was 95.9%. At 1 year after surgery, 10 cases (10.5%, 10/95) had severe anal dysfunction, and the median LARS score of the entire group was 5.0 (range: 0-41.0) points. Conclusions:For patients with locally advanced low rectal cancer who achieve cCR or near-cCR after neoadjuvant therapy, local excision results in favorable oncological prognosis and anal function preservation effects; however, the incidence of complications is relatively high.

Objective:To describe the prevalence and distributions of mood disorder in Inner Mongolia Au-tonomous Region,and analyze the related risk factors.Methods:The multistage stratified sampling method with un-equal probability was used to select permanent residents aged 18 years and over in Inner Mongolia Autonomous Re-gion.The Composite International Diagnostic Interview 3.0 was used as a diagnostic tool.Mood disorders were di-agnosed according to the Diagnostic and Statistical Manual of Mental Disorders Fourth Edition(DSM-Ⅳ).Single and multivariate analyses were used to investigate the related factors of mood disorders.Results:Totally,12 315 community residents were interviewed in the survey.The weighted 12-month prevalence and lifetime prevalence of mood disorder were 5.4％and 8.7％,respectively.Weighted 12-month prevalence of depressive disorder was 4.9％,and that of bipolar disorder was 0.3％.Among all subtypes of mood disorder,the 12-month prevalence rate of major depressive disorder(3.1％)was the highest.Multivariate logistic regression analysis showed that female,unmarried,separated or divorced,unemployment,family history,other mental disorders,sleep disorders and chronic diseases(OR=1.56,2.80,2.07,1.42,13.46,7.97,3.23,2.13)were risk factors of mood disorder,while aged 65 years and over(OR=0.44)was protective factor of mood disorders.The lifetime consultation rate in patients with mood disorders was 15.5％,the rate of psychiatric consultation was 3.7％,the rate of medication was 1.8％.Con-clusion:It indicates that female residents and people who are unmarried,separated and divorced,unemployed,with family history,suffering from other mental disorders,suffering from sleep disorders,and suffering from chronic dis-eases may be high risk groups of mood disorders,and the utilization rate of health services is rather low in Inner Mongolia Autonomous Region.

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.
