Objective: To analyze the risk factors of recurrence after transurethral resection of bladder tumor (TURBT) in patients with non-muscle-invasive bladder cancer (NMIBC)，and establish a risk prediction model，so as to optimize the clinical detection and management of NMIBC. Methods: A total of 174 patients with initial diagnosis of NMIBC who underwent TURBT in the First Affiliated Hospital of Xinjiang Medical University during Jan.2020 and Oct.2022 were followed up for 24 months，and were then divided into the recurrence group (n=74) and non-recurrence group (n=100).After univariate analysis and multivariate logistic regression，risk factors of recurrence were identified，a nomogram was established，and the calibration curve was plotted，which was verified with receiver operator characteristic (ROC) curve. Results: The 2-year recurrence rate was 42.53%.Logistic regression showed high body mass index (BMI)，poor differentiation，multiple tumors，and tumor diameter greater than 3 cm were risk factors of recurrence (P<0.05，OR≥1)，while immediate postoperative intravesical instillation was a protective factor (P<0.05).The C-index of the nomogram was 0.893 (95%CI:0.851-0.938)，the area of ROC curve (AUC) was 0.894 (95%CI：0.847-0.941)，the sensitivity was 82.4%，and the specificity was 83.0%. Conclusion: The prediction model based on BMI，tumor stage，grade，number，diameter，and immediate postoperative intravesical instillation fits well and can provide reference for predicting the risk of tumor recurrence.

Objective: To investigate the coexistence of comorbidity of myopia, overweight/obesity and depressive symptoms among middle school students in Quzhou and its associated factors, so as to provide evidence for integrated prevention and control of common multiple health issues in students. Methods: From September to November 2023, a total of 5 867 middle school students from 6 counties (cities and districts) in Quzhou City were selected by stratified random cluster sampling. Physical and visual examinations were conducted, and the Center for Epidemiological Studies - Depression Scale (CES-D) along with a questionnaire on health status and influencing factors were completed. Multivariate Logistic regression was used to analyze the related factors of coexistence of myopia, overweight/obesity, and depressive symptoms among middle school students, and a nomogram model was constructed based on the results. Results: A total of 161 middle school students in Quzhou City were identified as having comorbid myopia, overweight/ obesity and depressive symptoms, with a detection rate of 2.74%. The results of multivariate Logistic regression analysis showed that the coexistence of myopia, overweight/obesity and depressive symptoms increased among middle school students with older age ( OR =1.11), a greater number unhealthy dietary behaviors (1,2,≥3; OR =2.40, 2.70, 4.63), insufficient sleep( OR =1.78) and alcohol consumption ( OR =2.11)(all P <0.05). Compared with no homework after class, those whose homework duration after class was 1 to < 2 hour had a lower risk of comorbidity of myopia, overweight/obesity and depressive symptoms ( OR =0.53, P <0.05). The results of the nomogram model showed that the AUC (95% CI ) was 0.71 (0.67-0.74). Conclusions The coexistence of myopia, overweight/obesity and depressive symptoms among middle school students in Quzhou City is related to age, sleeping, alcohol consumption, poor dietary behavior and the duration of after school homework. The nomogram model can assist in the early screening and intervention of multiple health issues among students.

Objective To explore the protective effect and mechanism of Jinyinqingre oral liquid on acute lung injury in-duced by lipopolysaccharide(LPS)in mice.Methods C57BL/6J mice were randomly divided into six groups according to the random number table method:blank control group,model control group,Jinyinqingre oral liquid low-dose group,Jinyinqingre oral liquid medium-dose group,Jinyinqingre oral liquid high-dose group,and dexamethasone group.Except for the blank control group,the other groups were injected with lipopolysac charide(LPS)(5 mg·kg-1)into the trachea to establish the acute lung injury model of mice,and the Jinyinqingre oral liquid low,medium,and high groups were continuously administered the drug by gavage for three days.After 24 h,lung tissue and bronchoalveolar lavage fluid(BALF)were collected from the six groups for follow-up detection.The pathological injury of lung tissue in each group was observed by HE staining.The total number of cells in BALF was detected.The to-tal protein content of BALF was detected by the BCA method.The contents of inflammatory cytokines TNF-α,IL-1β,IL-6,and IgM in BALF were detected by ELISA.The expression of NF-κB and NLRP3 proteins in lung tissues was detected by immunohistochemistry and Western blotting.Results Compared with model control group,Jinyinqingre oral liquid alleviated the pathological injury of lung tissue(P＜0.05),decreased the total cell count,total protein content and IgM expression in BALF(P＜0.01),and the expres-sion of inflammatory cytokines TNF-α,IL-6 and IL-1β in BALF was dreased(P＜0.05),the protein expressions of NF-κB and NL-RP3 in lung tissues was dreased(P＜0.05).Conclusion Jinyinqingre oral liquid attenuated the pathological injury,inflammatory exudation,and expression of inflammatory cytokines in LPS-induced lung injury in mice,and its mechanism may be through the reg-ulation of NF-κB/NLRP3 signaling pathway,providing a theoretical basis for its clinical application.

Individuals with type 1 diabetes or advanced type 2 diabetes suffer insufficient insulin secretion, leading to symptoms of hyperglycemia. To maintain the normal blood glucose levels, those people with diabetes must administer insulin multiple times a day. However, insulin requirements are influenced by several factors such as diet, exercise, and illness, combined with the narrow therapeutic index, making accurate insulin dosage challenging. Excessive insulin administration can even pose life-threatening risks. In addition, frequent daily insulin injections place considerable physiological and psychological burdens on patients. To tackle these challenges, researchers have embarked on the development of closed-loop insulin delivery systems. These systems adjust insulin dosages in real-time changes based on the patient’s blood glucose levels, therefore enhancing both the safety and effectiveness of insulin therapy. This review categorizes closed-loop insulin delivery systems into two types: electronic-based and material-based systems, based on their compositional attributes. The exploration of both types covers their components, developmental history, clinical applications, current pros and cons, and future directions. The relative strengths and limitations of these two categories of closed-loop insulin delivery systems are also compared and discussed.

In January 2021, an acute chemical poisoning incident occurred at a fluorine polymerization plant. Through the analysis of the occupational health situation of the enterprise, combined with the clinical manifestations of the poisoned patients and the laboratory examination results, it was determined that the incident was an acute poisoning incident caused by the inhalation of organic fluorine mixed gas in the fluorine polymerization plant. Subsequently, it was clarified that the accident was caused by the illegal operation of the employees of the fluorine polymerization plant, which caused the discharge of the organic fluorine mixed gas containing high concentration of octafluoroisobutene, resulting in the poisoning of the on-site construction personnel. In order to avoid the occurrence of similar incidents, enterprises should implement the main responsibility of safety production, regularly organize supervision and inspection, eliminate illegal operations, conduct safety education and training for the staff of the unit and outsourced staff, and improve the emergency rescue ability of sudden poisoning incidents.

Objective:To compare the efficacy of Kirschner wire fixation combined with Suture-Bridge technique and simple Kirschner wire fixation in the treatment of old lateral malleolar avulsion fractures under all-inside arthroscopy.Methods:A retrospective cohort study was conducted to analyze the clinical data of 56 patients with old lateral malleolar avulsion fractures, admitted at Xuzhou Central Hospital from January 2018 to June 2022, including 32 males (32 feet) and 24 females (24 feet), aged 19-57 years [(35.2±11.1)years]. Twenty-five patients were treated with Kirschner wire fixation under all-inside arthroscopy (K-wire group), while the other 31 patients were treated with Kirschner wire fixation combined with Suture-Bridge technique under all-inside arthroscopy (K-wire combined with suture group). The surgical time, incision healing at 2 weeks after surgery, and fracture healing rate at 6 months after surgery of the two groups were detected. The American Orthopedic Foot and Ankle Society (AOFAS) ankle-hindfoot scores, and foot and ankle ability measure (FAAM) scores [including activities of daily living (ADL) scores and sports function (S) scores] of the two groups were assessed before surgery, at 3, 6 months after surgery, and at the last follow-up. The anterior drawer test was performed at 3, 6 months after surgery and at the last follow-up. The time of return to sports after surgery and complication rates were also recorded.Results:All the patients were followed up for 12-18 months [(14.2±2.2)months]. The surgical time in the K-wire combined with suture group was (56.3±12.5)minutes, longer than (41.1±8.2)minutes in the K-wire group ( P<0.01). The incisions in both groups were healed by first intention at 2 weeks after surgery. In the K-wire combined with suture group, all the fractures were healed at 6 months after surgery (100%), while in the K-wire group 22 patients (88%) obtained fracture healing ( P<0.05). There were no statistically significant differences in the AOFAS ankle-hindfoot scores, FAAM-ADL scores, or FAAM-S scores between the two groups preoperatively ( P>0.05). At 3, 6 months after surgery, and at the last follow-up, the AOFAS ankle-hindfoot scores in the K-wire combined with suture group were (89.7±3.4)points, (92.8±2.8)points, and (94.9±3.3)points respectively, higher than (87.4±4.4)points, (90.4±4.1)points, and (92.5±4.6)points in the K-wire group ( P<0.05); the FAAM-ADL scores and the FAAM-S scores in the K-wire combined with suture group were (90.1±3.5)points, (91.5±2.9)points, (92.8±3.0)points and (91.4±5.4)points, (92.8±5.0)points, (94.4±4.8)points respectively, higher than (86.8±5.0)points, (88.7±3.8)points, (90.3±3.7)points and (88.0±5.3)points, (89.5±4.8)points, (91.5±5.2)points ( P<0.05 or 0.01). The AOFAS ankle-hindfoot scores, FAAM-ADL scores, and FAAM-S scores at all postoperative time points were higher than those preoperatively and increased with the passage of the follow-up time ( P<0.01). The results of the anterior drawer test at all postoperative time points in the two groups were negative. The time of return to sports after surgery in the K-wire combined with suture group was (9.2±1.3)weeks, shorter than (10.3±1.5)weeks in the K-wire group ( P<0.01). One patient (3.2%) in the K-wire combined with suture group and 3 patients (12.0%) in the K-wire group had Kirschner wire loosening and withdrawal ( P>0.05). Neither of the two groups developed complications such as nerve or tendon injuries. Conclusion:Compared with simple Kirschner wire fixation under all-inside arthroscopy, Kirschner wire fixation combined with Suture-Bridge technique under all-inside arthroscopy achieves higher fracture healing rate, more obvious improvement in life quality and ankle function, as well as earlier return to sports in the treatment of old lateral malleolar avulsion fractures.

Objective:To study the clinical efficacy of percutaneous transhepatic cholangial drainage (PTCD) and primary closure of common bile duct after laparoscopic common bile duct exploration (LCBDE) in treatment of choledocholithiasis complicated with moderate and severe cholangitis.Methods:The clinical data of 127 patients with choledocholithiasis complicated with acute cholangitis admitted to Yantai Affiliated Hospital of Binzhou Medical University from January 2021 to August 2023 were retrospectively analyzed. Finally, 45 patients were enrolled, including 20 males and 25 females, aged (71.3±8.2) years. All 45 patients were treated with sequential PTCD and primary closure of common bile duct after LCBDE. The interval from PTCD to primary closure, white blood cell count, total bilirubin, alanine transaminase before and after PTCD, operation time of primary closure, intraoperative blood loss, postoperative retention time of abdominal drainage tube, postoperative hospitalization time, postoperative complications (bile leakage, bleeding, etc.) were analyzed.Results:The serum total bilirubin, alanine transaminase and white blood cell count of 45 patients were (143.2±32.1) μmol/L, (173.6±23.4) U/L, (16.3±2.9)×10 9/L at admission, and (100.5±21.4) μmol/L, (103.5±12.7) U/L, (8.6±1.7) ×10 9/L after PTCD, respectively. The interval between PTCD and primary closure of common bile duct after LCBDE was (4.3±1.1) d, the operative time of primary closure was (123.4±20.5) min, the amount of intraoperative blood loss was (32.6±8.7) ml. The postoperative hospitalization time was (6.8±1.6) d, and the postoperative retention time of abdominal drainage tube was (4.5±1.3) d, and postoperative complications occurred in 7 cases (15.6%), including biliary leakage in 4 cases (8.9%), subxiphoid incision infection in 1 case (2.2%), and effusion in gallbladder fossa with infection in 2 cases (4.4%). Conclusion:The sequential application of PTCD and primary closure of common bile duct after LCBDE in treatment of choledocholithiasis complicated with moderate and severe cholangitis is a safe, effective and minimally invasive method, and primary closure of common bile duct after LCBDE is safe and reliable within 1 week after PTCD.
