Objective: To investigate the influencing factors of overactive bladder (OAB) in college freshmen and the impacts of OAB on their mental health, quality of life and social interaction. Methods: An epidemiological questionnaire survey was conducted in an anonymous manner on the prevalence of OAB among 5300 freshmen aged 17 to 22 years enrolled in the 2023—2024 academic year in Xinxiang Medical University and Sanquan College of Xinxiang Medical University.The questionnaire included questions on basic information, history of urinary tract infection, constipation, smoking, history of alcohol consumption, history of coffee/strong tea drinking, history of carbonated beverage drinking, redundant prepuce, phimosis, holding urine, chronic insomnia, self-rating anxiety scale (SAS), quality of life score (QoL), and social avoidance and distress scale (SADS).The influencing factors of OAB were analyzed with multivariate logistic regression analysis.The subjects were grouped according to whether they had OAB, and the differences in SAS, QoL and SADS between the OAB group and non-OAB group were compared.The impacts of OAB on the anxiety level, quality of life, and social interaction were analyzed with multiple linear regression analysis. Results: The overall prevalence rate of OAB was 4.9% (244/5018).Multivariate logistic regression analysis showed that the history of urinary tract infection (OR=0.177), constipation (OR=0.636), smoking (OR=0.582), alcohol consumption (OR=0.685), coffee/strong tea drinking (OR=0.387), carbonated beverage drinking (OR=0.631), redundant prepuce (OR=0.673), phimosis (OR=0.311), urine holding (OR=0.593), and chronic insomnia (OR=0.256) were influencing factors for the occurrence of OAB (P＜0.05).The OAB group had higher SAS score [(41.18±6.54) vs. (38.61±6.36)], QoL score [(3.65±1.20) vs. (2.79±0.95)], social avoidance score [(6.25±1.86) vs. (5.86±1.51)], social distress score [(6.27±1.59) vs. (5.97±1.32)], and total SADS score [(12.51±2.35) vs. (11.84±2.01)] than the non-OAB group (P＜0.05).The results of multiple linear regression analysis showed that OAB could independently affect the scores of QoL, SAS, and SADS.The OAB group had higher scores of QoL, SAS, and SADS compared with the non-OAB group (P＜0.001). Conclusion: History of urinary tract infection, constipation, smoking, alcohol consumption, coffee/strong tea drinking, carbonated beverage drinking, redundant prepuce, phimosis, urine holding, and chronic insomnia are influencing factors for the occurrence of OAB in male college students.Moreover, OAB has negative impacts on their mental health, quality of life, and social interaction.

Objective:To compare the safety and efficacy of two-person and three-person operation of endoscopic retrograde cholangiopancreatography (ERCP) after Roux-en-Y anastomosis.Methods:A total of 31 cases of bile duct stones where endoscopic access was successful and papilla was detected after Roux-en-Y anastomosis in Hangzhou First People's Hospital from January 2021 to September 2022 were recruited. Based on the retrospective study, 17 patients with the two-person operation (an operator and an assistant completed selective intubation) were included in group A from January to December 2021, and 14 patients with the three-person operation (an operator and two assistants completed the selective intubation) from January to September 2022 were included in group B. The success rate, the time of intubation, and complication incidence of the two groups were compared.Results:The intubation success rate of all enrolled patients was 90.32% (28/31). There was no significant difference in the intubation success rate between group A and group B [82.35% (14/17) VS 100.00% (14/14), P=0.232]. The intubation time in group B was significantly less than that of group A (42.89±6.57 min VS 61.02±9.23 min) with significant difference ( t=5.77, P<0.001). The incidence of postoperative complication of ERCP in all enrolled patients was 16.13% (5/31). There was no significant difference in the postoperative complication incidence between group A and group B [17.65% (3/17) VS 14.29% (2/14), P=1.000]. Conclusion:For patients undergoing ERCP after Roux-en-Y anastomosis, the two methods were not statistically different in terms of the intubation success rate and the incidence of procedure-related complications. But three-person operation shows clear advantage in terms of operation time.

ObjectiveTo investigate whether paeonol exerts a protective effect on mice with alcoholic liver injury by regulating the takeda G-protein-coupled receptor 5 （TGR5）/protein kinase A （PKA）/cAMP response binding element （CREB） signaling pathway mediated by Eubacterium. MethodC57BL/6 mice were randomly divided into five groups： normal group， model group， paeonol group （480 mg·kg^-1）， antibiotic group （Abs group）， and antibiotic + paeonol group. Lieber-DeCarli liquid was used to feed C57BL/6 mice on the second day of modeling for 10 days. The blood lipids， liver function， inflammatory factors， and oxidative stress levels in mice were measured. Hematoxylin-eosin staining （HE） and oil red O staining were used to observe the morphological changes and fat accumulation in liver tissue. 16S rDNA sequencing was used to detect the diversity of intestinal microbiota in the blank， model， and paeanol groups. Western blot was used to detect the effect of paeonol on the expression levels of protein related to the signaling pathway of atresia band protein 1 （ZO-1）， Claudin-1， and TGR5/PKA/CREB in mouse ileal tissue. ResultCompared with those in the blank group， the blood lipids， liver function， oxidative stress levels， and the expression of inflammatory factors in the model group increased （P<0.01）， and the liver fat vacuoles were obvious. The ileal mucosa was seriously damaged， and the protein contents of ZO-1， Claudin-1， and TGR5/PKA/CREB in the ileal tissue decreased significantly （P<0.01）. The intestinal microbiota changed， and the proteobacteria phylum increased significantly. The ratio of Bacteroidetes to Firmicutes decreased. The relative abundance of Dubosiella newyorkensis， Lactobacillus， Bifidobacterium， and other genera decreased， while the relative abundance of Escherichia-Shigella， Morganella， Providencia， and Proteus increased significantly. Compared with the model group， paeonol significantly reduced the blood lipids， liver function， oxidative stress levels， and expression of inflammatory factors in mice with alcohol diet-induced liver injury （P<0.05）， decreased liver fat vacuoles， improved and restored the ileal intestinal barrier， and restored the normal structure of hepatocytes and ileal cells. The intestinal microbiota disorder caused by alcohol was improved， and the relative abundance of beneficial bacteria such as Eubacterium spp. was increased. The protein expression levels of ZO-1， Claudin-1， and TGR5/PKA/CREB in ileal tissue were increased （P<0.05）. ConclusionPaeonol has a protective effect on alcoholic liver injury in mice， and the mechanism of action is achieved by regulating the Eubacterium-mediated TGR5/PKA/CREB signaling pathway to ensure anti-inflammatory effect and improve the intestinal barrier.

ObjectiveTo investigate the immunological characteristics of the patients with aplastic anemia （AA） and elevated hemogram parameters treated with Yiqi Yangxue prescription combined with Western medicine and the predictive effects of immunological indexes on elevated hemogram parameters， thus providing a reference for the prediction of the treatment efficacy and the adjustment of the treatment regimen. MethodA retrospective study was conducted， involving 77 AA patients treated with Yiqi Yangxue prescription combined with Western medicine for 6 months in 19 medical institutions including Xiyuan Hospital， China Academy of Chinese Medical Sciences from September 2018 to March 2021. The patients were assigned into two groups according to the elevations in hemogram parameters ［including hemoglobin （HGB）， white blood cell count （WBC）， platelet （PLT）， and absolute neutrophil count （ANC）］ after 6 months of treatment. One group had the elevation <50%， and the other group had the elevation ≥50% compared with the baseline. The clinical and immunological characteristics were compared between the two groups. Result① Compared with the group with HGB elevation<50%， the group with HGB elevation≥50% showed elevated level of CD3⁺ human leukocyte antigen-DR （HLA-DR）⁺ and increased proportion of patients with T-helper cell type 2 （Th2）<5%， CD8⁺≥50%， and CD3⁺HLA-DR⁺≥9% before treatment （P<0.05， P<0.01）. The multivariate Logistic regression analysis showed that CD8⁺≥50% before treatment was the independent influencing factor for HGB elevation ≥50% ［odds ratio （OR）=12.000， 95% confidence interval （CI） 2.218， 64.928， P<0.01］. ② Compared with the group with WBC elevation<50%， the group with WBC elevation≥50% showed increased proportion of patients with CD3⁺HLA-DR⁺<6% and T-box transcription factor （T-bet）≥200% before treatment （P<0.05）. The multivariate Logistic regression analysis showed that CD3⁺HLA-DR⁺<6% （OR=2.998， 95%CI 1.036， 8.680， P<0.05） and T-bet≥200% （OR=3.634， 95%CI 1.076， 12.273， P<0.05） before treatment were independent influencing factors for WBC elevation≥50%. ③ Compared with the group with PLT elevation<50%， the group with PLT elevation≥50% presented lowered Th1 and CD3⁺HLA-DR⁺ levels and increased proportion of patients with Th1<12%， CD4⁺≥6%， and CD3⁺HLA-DR⁺<5% before treatment （P<0.05， P<0.01）. The multivariate Logistic regression analysis showed that CD3⁺HLA-DR⁺<5% before treatment was the independent influencing factor for PLT elevation≥50% （OR=16.190， 95%CI of 3.430 to 76.434， P<0.01）. ④ Compared with the group with ANC elevation<50%， the group with ANC elevation≥50% showed no significant changes in the hemogram parameters before treatment. ConclusionAs for the AA patients with rapid elevation in HGB， Yiqi Yangxue prescription combined with Western medicine demonstrate significant effects in the patients with Th2<5% and CD3⁺HLA-DR⁺≥9%， especially those with CD8⁺≥50%. As for the AA patients with rapid elevation in WBC， the therapy was particularly effective in the patients with CD3⁺HLA-DR⁺<6% and T-bet≥200%. As for the AA patients with rapid growth in PLT， the therapy was particularly effective in the patients with Th1<12% and CD4⁺≥6%， especially those with CD3⁺HLA-DR⁺<5%.

Objective:To comprehensively evaluate the performance of the iterative cone beam CT (iCBCT) imaging mode of Varian linear accelerators and to explore its specific advantages in clinical application.Methods:The kV cone beam CT (CBCT) imaging systems of Halcyon 2.0, Edge, and VitalBeam linear accelerators from Tianjin Medical University Cancer Institute & Hospital were selected, among which Halcyon 2.0 and Edge were equipped with the iCBCT imaging mode. The Penta-Guide phantom was used to evaluate the registration accuracy of iCBCT imaging modes. The accuracy of treatment couch position was measured by a ruler. The image quality of the iCBCT and conventional CBCT modes of various imaging devices were analyzed using the CatPhan604 phantom. The imaging beam-on time and reconstruction time were measured to assess image acquisition efficiency. The uniformity, spatial resolution, contrast, contrast-to-noise ratio (CNR), image acquisition time and reconstruction time between two imaging modes were statistically analyzed by t-test. Results:The maximum deviations of image registration measurement results of the iCBCT mode for Halcyon 2.0 and Edge accelerators compared to the standard values were 0.7 mm and 0.6 mm, respectively. The treatment couch position error of all devices was less than 1 mm. The iCBCT images under head scanning protocol primarily improved the uniformity and CNR. Compared to conventional CBCT images, Halcyon iCBCT increased the uniformity and CNR by 2.50% ( P<0.001) and 78.85% ( P<0.001), respectively, while Edge increased them by 2.18% ( P<0.001) and 86.42% ( P<0.001), both superior to VitalBeam CBCT images. Under pelvis scanning protocols, iCBCT images primarily improved the CNR compared to conventional CBCT images. Halcyon and Edge iCBCT increased the CNR by 113.57% ( P<0.001) and 133.87% ( P<0.001), respectively, both superior to VitalBeam CBCT images. In terms of image acquisition efficiency, the average reconstruction times for Halcyon and Edge iCBCT images increased by 7.28 s and 15.53 s, respectively, and the total image acquisition time of Halcyon accelerator was the shortest. Conclusions:While ensuring the registration accuracy, iCBCT imaging mode can significantly improve the CNR of images and improve the uniformity of images under head scanning protocol. The Halcyon imaging system can enhance image acquisition efficiency.

Objective:To systematically investigate the short-term efficacy of total knee arthroplasty in the treatment of osteoarthritis coupled with fixed patellar dislocation.Methods:A retrospective analysis was conducted on a cohort of 11 patients diagnosed with knee osteoarthritis and fixed patellar dislocation who underwent total knee arthroplasty at Panzhihua Central Hospital from January 2018 to October 2021. The cohort comprised 4 males and 7 females, aged 63.45±4.76 years (range, 56-70 years), all of whom underwent unilateral surgery. There were 5 left and 6 right knees, with a body mass index of 23.20±2.02 kg/m 2 (range, 20.8-27.6 kg/m 2) and a disease course of 12.63±4.81 years. According to the American Society of Anesthesiologists classification, 9 cases were categorized as grade II, and 2 cases as grade III. Recovery of patellar trajectory during total knee arthroplasty, using medial synovial flap transposition to repair lateral joint capsule. Preoperative and postoperative assessments included knee joint range of motion, Knee Society score (KSS), University of California Los Angeles (UCLA) score, and visual analogue scale (VAS). Results:All 11 patients were followed up for a period of 28.64±4.01 months (range, 24-36 months). Two patients exhibited subcutaneous fat liquefaction locally after surgery, which resolved following dressing changes. All wounds achieved primary healing. Two of them developed intramuscular vein thrombosis after surgery and were cured after anticoagulant treatment. The range of motion of the knee joint increased from 63.18°±17.07° before surgery to 104.55°±16.80° at the last follow-up, with a statistically significant difference ( t=14.041, P<0.001). The KSS score increased from 38.00±6.78 points to 80.91±5.65 points, with a statistically significant difference ( t=16.472, P<0.001). The UCLA score increased from 3.18±1.17 to 6.73±1.35, with a statistically significant difference ( t=9.694, P<0.001). The VAS decreased from 6.09±0.94 points to 2.32±0.64 points, with a statistically significant difference ( t=16.600, P<0.001). At the last follow-up, imaging examinations showed no cases of patellar subluxation or dislocation, no tearing or breakage of the knee extension device, and no infection or loosening around the prosthesis. Conclusion:Utilizing medial synovial flap transposition for repairing the lateral joint capsule proves to be an effective technique for key capsule repair. Total knee arthroplasty for osteoarthritis combined with fixed patellar dislocation demonstrates satisfactory early clinical outcomes.

Ischemic stroke（IS） is a common cerebrovascular disease in clinics，with a high disability rate. In recent years，the incidence of IS has gradually increased，especially in young people，which seriously affects the physical and mental health and quality of life of patients. Western medicine has made some progress in the treatment of IS but still faces some limitations. Therefore， choosing a measure that can assist in the treatment of IS is particularly important. A large number of studies have confirmed that traditional Chinese medicine can treat IS based on the effective ingredients and extracts of traditional Chinese medicine monomers and formulas，utilizing advantages such as multiple targets，multiple bioactive ingredients，multiple systems，and fewer adverse reactions to ensure the safety and effectiveness of the treatment pathway. At present，the mechanism of action of traditional Chinese medicine in treating IS can be achieved by intervening in various signaling pathways，mainly including secretory glycoprotein/β-catenin（Wnt/β-catenin） signaling pathway，phosphatidylinositol 3-kinase/protein kinase B（PI3K/Akt） signaling pathway，nuclear factor kappa-B（NF-κB） signaling pathway，Toll-like receptor 4/NOD-like receptor protein 3（TLR4/NLRP3） signaling pathway，mitogen-activated protein kinase（MAPK） signaling pathway，and neurogenic site-gap homologous protein（Notch） signaling pathway. This article summarized the relationship between IS and related signaling pathways in recent years，as well as the regulation of IS-related pathways and corresponding mechanisms by traditional Chinese medicine，so as to provide a reference for future clinical and experimental research on IS.

With the development of clinical related disciplines, the update and establishment of relevant standards/guidelines at home and abroad, GBZ 185-2006 Diagnostic Criteria for Occupational Medicamentose-like Dermatitis due to Trichloroethylene (hereinafter referred to as “GBZ 185-2006”) was unable to meet clinical needs. Therefore, the GBZ 185-2006 was revised based on the principles of evidence-based medicine, in accordance with relevant laws/regulations and relevant standards/guidelines in combination with review of research data on occupational medicamentose-like dermatitis due to trichloroethylene (OMDT) home and abroad, and the development of clinical practice and clinical related disciplines. The main modifications include: adding terms and definitions of OMDT, modifying the description of clinical manifestations of the diagnostic principles, adjusting the description of latency, deleting the diagnostic requirement of the incidence probability, adding the specific allergen patch test as the etiological diagnostic index, standardizing the application scope, operating procedure and precautions of the specific allergen patch test. In addition, the relevant content of “Basic Characteristics and Clinical Types of Skin Damage of Medicamentose-like Dermatitis due to Trichloroethylene” in Appendix A is improved, the treatment principles are revised, and the content of new progress in treatment, artificial liver application, are added. The revised GBZ 185-2024 Diagnostic Standard for Occupational Medicamentose-like Dermatitis due to Trichloroethylene is more scientific and practical, and can provide technical basis for the standardized diagnosis and treatment of OMDT in medical and health institutions.

Objective:To introduce the experience of reconstructing the pelvic floor with a pedicled large omental flap combined with a basement membrane biological mesh in combined pelvic organ resection for locally advanced or locally recurrent rectal cancer combined with sacrococcygeal resection, and to discuss the feasibility, safety, and near-term therapeutic efficacy of this technique.Methods:For patients with sacrococcygeal resection of combined pelvic organs, a basement membrane mesh was used to rebuild the pelvic floor with a pedicled greater omentum flap to isolate the abdominopelvic cavity. The main operation was to pull the greater omentum, which preserved the double vascular arches, to the pelvic floor to cover the pelvic floor, and then the mesh was used to cover the posterior peritoneal defect and pelvic inlet with absorbable sutures of 2-0 or thicker.Results:In this study, a retrospective cohort study was used to collect clinical data through the China Rectal Cancer Combined Pelvic Organs Resections Case Database. Twenty patients with locally advanced or locally recurrent rectal cancer without extra-pelvic metastasis or only oligometastases underwent combined pelvic organ and sacrococcygeal resection in the Department of Anal and Intestinal Surgery of the Second Affiliated Hospital of the Naval Military Medical University during the period of July 1, 2022, to June 30, 2023, and 10 patients underwent simple basement membrane resection with a simple basement membrane. Among them, the pelvic floor were reconstructed by basement membrane mesh alone in 10 cases (mesh only group), and 10 cases were reconstructed the pelvic floor by pedicled large omental flap combined with basement membrane mesh (omental flap-combined mesh group). The recent outcomes of the two groups of patients were studied comparatively. Comparison of baseline data and intraoperative conditions between the two groups showed no statistically significant differences (all P>0.05); the drain removal time in the omental flap-combined mesh group was 26.7 (19-42) days, which was shorter than that in the mesh only group, which was 40.4 (24-56) days ( U=4.125, P=0.001); The empty pelvis healing time in the omental flap-combined mesh group was 29.4 (23~43) days, which was shorter than that of 42.2 (27~58) days in the mesh-only group ( U=4.043, P=0.001); the differences were all statistically significant. The postoperative complication rate of grade ≥III in the omental flap-combined mesh group was 1/10, which was lower than that of 6/10 in the mesh-only group; the difference was not statistically significant when comparing the two groups ( P = 0.057). Follow-up ended on 09/30/2023, with a median follow-up of 9.5 (3-15) months in 20 patients, and all 20 cases survived during the follow-up period, with no tumor recurrence at the surgical site. Conclusion:In locally advanced or locally recurrent rectal cancer undergoing combined pelvic organ resection with sacrococcygeal, compared with reconstruction of the pelvic floor by basement membrane mesh alone, reconstruction of the pelvic floor and isolation of the abdominopelvic cavity by a pedicled greater omentum flap combined with a basement membrane mesh is safe and feasible.

Objective To explore the mediating effect of triglyceride-glucose(TyG)index on the risk of proteinuria in patients with type 2 diabetes mellitus(T2DM).Methods 734 patients with T2DM who underwent routine physical examination in Quyang Road Community Health Service Center,Shanghai from March 2023 to May 2023 were enrolled.The results of basic information,biochemical indicators,abdominal ultrasound and other results were collected.All patients were divided into the normal group,microproteinuria group,and massiveproteinuria group,and stratification analyses were underwent according to glycated hemoglobin(HbA1c),body mass index(BMI),TyG index,and presence or absence of non-alcoholic fatty liver disease(NAFLD).Factors affecting proteinuria in T2DM patients were analyzed.Multivariate logistic regression was used to analyze the impact of TyG index and NAFLD on proteinuria in type 2 diabetes population.Regression coefficient sequential test was used to analyze whether TyG mediates NAFLD associated proteinuria.Results There were statistically significant differences in age,BMI,urinary creatinine,HbA1c,TyG index,etc.among the normal group,microproteinuria group,and massiveproteinuria group(all P＜0.05);there was no statistically significant difference in gender among the three groups.Multivariate logistic regression analysis showed that taking the HbA1c＜7％and BMI＜24 kg/m2 group as a reference,the patients with HbA1c≥7％and BMI≥24 kg/m2 had the highest risk of proteinuria(P=0.022),followed by the HbA1c≥7％and BMI＜24 kg/m2 group(P=0.039).Taking the TyG index(7.65-8.69)as a reference,the risk of proteinuria in the(9.45-11.90)group was 3.321 times(P＜0.001).The mediation effect analysis showed that the TyG mediated NAFLD associated proteinuria(P＜0.001),with the mediation effect accounting for 55.70％of the total effect.Conclusion TyG index may be an independent risk factor for proteinuria in patients with T2DM,and the prevalence of proteinuria is high in patients with poor control in HbA1c and excessive BMI,and TyG may partially mediate the risk of proteinuria in patients with T2DM.
