Objective To compare the clinical effects of arthroscopically-assisted reduction and internal fixation(ARIF)combined with enhanced recovery after surgery(ERAS)and open reduction and internal fixation surgery(ORIF)in the treatment of posterior lateral tibial plateau fractures.Methods Seventy patients with posterior lateral tibial plateau fractures in the Department of Orthopaedics,Xuzhou Central Hospital,from January 2020 to November 2022 were retrospectively selected and divided into ARIF group(with ERAS,n=32)and ORIF group(without ERAS,n=38)according to the treatment methods.All patients were evaluated for fracture type by imaging examination after admission.The operation time,length of hospital stay,early postoperative pain score(evaluated by visual analogue scale[VAS]),knee joint function(evaluated by hospital for special surgery[HSS]scale)at 3 months and thigh circumference difference at 6 months postoperatively were compared between the two groups.Results The operation time in the ARIF group was significantly shorter than that in the ORIF group([67.84±9.89]min vs[85.16±9.18]min,P＜0.001),and the length of hospital stay was significantly shorter in the ARIF group([7.13±1.41]d vs[8.74±1.84]d,P＜0.001).On the third day after operation,the VAS score in the ARIF group was significantly lower than that in the ORIF group([4.00±1.44]vs[5.39±1.24],P＜0.001).ARIF group had better joint function than ORIF group 3 months after operation,and the difference of 10 cm thigh circumference on patella in ARIF group was smaller than that in ORIF group 6 months after operation.Conclusions Compared to ORIF,patients with posterior lateral tibial plateau fractures treated with ARIF combined with ERAS showed faster postoperative recovery,shorter hospital stay,and more precise clinical efficacy.

Objective To propose a classification method for ultrasound images of pedicle screw canals based on radiomics analysis,and to evaluate the integrity of the screw canal.Methods With thoracolumbar spine specimens from 4 fresh cadavers,50 pedicle screw canals were pre-established and ultrasound images of the canals were acquired.A total of 2 000 images(1 000 intact and 1 000 damaged canal samples)were selected.The dataset was randomly divided in a 4∶1 ratio using 5-fold cross-validation to form training and testing sets(consisting of 1 600 and 400 samples,respectively).Firstly,the optimal radius of the region of interest was identified using the Otsu's thresholding method,followed by feature extraction using pyradiomics.Principal component analysis and the least absolute shrinkage and selection operator algorithm were employed for dimensionality reduction and feature selection,respectively.Subsequently,3 machine learning models(support vector machine[SVM],logistic regression,and random forest)and 3 deep learning models(visual geometry group[VGG],ResNet,and Transformer)were used to classify the ultrasound images.The performance of each model was evaluated using accuracy.Results With a region of interest radius of 230 pixels,the SVM model achieved the highest classification accuracy of 96.25%.The accuracy of the VGG model was only 51.29%,while the accuracies of the logistic regression,random forest,ResNet,and Transformer models were 85.50%,80.75%,80.17%,and 75.18%,respectively.Conclusion For ultrasound images of pedicle screw canals,the machine learning model performs better than the deep learning model as a whole,and the SVM model has the best classification performance,which can be used to assist physicians in diagnosis.

Objective: To describe the status of non-steroidal anti-inflammatory drugs (NSAIDs) use in areas with a high incidence of upper gastrointestinal cancer in China. Methods: This study was based on the National Key Research and Development Program of "National Precision Medicine Cohort of Esophageal Cancer" and "Study on Identification and Prevention of High-risk Populations of Gastrointestinal Malignancies (Esophageal cancer, Gastric cancer and Colorectal cancer)" . From January 2017 to August 2018, 212 villages or communities with a high incidence of esophageal cancer or gastric cancer were selected from 12 regions in 6 provinces. A total of 35 910 residents aged between 40 and 69 years old who met the inclusion criteria and signed the informed consent were investigated and enrolled in this study. The use of NSAIDs, demographic characteristics, health-related habits, height, weight, and blood pressure were collected by the questionnaire and physical examination. The status of main NSAIDs (aspirin, acetaminophen and ibuprofen) use with the difference varying in genders, age groups and regions were analyzed by using χ² test and Cochran-Armitage trend analysis method. Results: Of 35 910 subjects, the mean age was (54.6±7.1) years old and males accounted for 43.42% (15 591). The overall prevalence of NSAIDs intake was 4.56% (1 638), but it significantly varied in different provinces (P<0.001). The overall prevalence of NSAIDs intake was 4.87% (1 750) in females, which was significantly higher than that in males 4.24% (1 524) (P<0.001). The prevalence of NSAIDs intake increased with age (P for trend <0.001). As the frequency of NSAIDs intake increased, the incidence of gastrointestinal symptoms, gastrointestinal ulcers and black stools increased (P for trend <0.05 for all). Conclusion The use of NSAIDs is prevalent in some areas with a high incidence of upper gastrointestinal cancer in China. The increased use of NSAIDs may lead to more adverse effects related to the gastrointestinal tract.

Objective The concentration of NE and TNF-α was detected for elucidating the change of them in sera and bronchoalveolar lavage fluid (BALF) of rabbits with acute lung injury interposed by XueBiJing therapy in underwater explosion.Methods Underwater explosion decive was applied to cause acute lung injury of rabbits.The 20 rabbits were randomly divided into two groups which were injury group and XueBiJing therapy group,respectively.The concentration of NE and TNF-α in sera and BALF were detected by ELISA method in 24 hours after bursting.Results The concentration of TNF-α in sera (353.30±166.86 ng/L) of rabbits in therapy group were significantly lower than those in injury group (552.30± 169.64 ng/L;t=2.645,P =0.016).The concentration of NE in sera (63.40 ± 36.09 ng/ml) were lower than that of rabbits in injury group (97.60 ± 36.20 ng/ml;t=2.116,P=0.049).At the same time the concentration of NE in BALF (102.10± 9.50 ng/ml) of rabbits in therapy group were significantly lower than those in injury group (136.70± 13.60 ng/ml;t=6.593,P=0.000).Conclusion The expression of TNF-α in sera and NE in sera and BALF in rabbits with acute lung injury interposed by XueBiJing in underwater explosion were lower than those of injury group.

Objective The expression of TNF-α was detected in sera of rabbits treated by ulinastatin with acute lung injury in duced by underwater explosion.Methods Rabbits were randomly divided into two groups such as the injured group and ulinastatin therapy group.Established underwater explosion device was used to cause acute lung injury in rabbits.TNF-α in sera of the rabbits were measured by ELISA at 4,12 and 24 hours after the explosion.The SPSS17.0 software was used to analyze the data and P＜0.05 was considered to be significant.Results There was no significant difference between the concentrations of TNF-α in the sera of rabbits in the injure group (538.20±201.43 ng/L) and that of in the ulinastatin group (386.90± 109.22 ng/L,t=2.088,P=0.051) at 4 hours after burst.However,there was evidently decreased in the level of TNF-α in the ulinastatin group (400.60 ± 78.98 ng/L) compared with the injury group (573.80 ± 178.24 ng/L,t =2.809,P =0.012) at 12 hours after burst.Moreover and TNF-α in the ulinastatin group (356.10 ± 130.99 ng/L) was also decreased compared to the injure group (552.30± 169.64 ng/L,t=2.895,P=0.010) at 24 hours after burst.Conclusion The TNF-α expression in sera of the rabbits in ulinastatin group were dramatically decreased than thai of in injury group at 12 hours after burst,which may be benefit to rabbits with acute lung injury induced by underwater explosion.

This study investigated the prevalence and risk factors of urinary incontinence (UI) among perimenopausal women in Wuhan. A cross-sectional survey was performed on 1067 women aged 40-65 years sampled in Wuhan urban area from April to October 2014. Information about demographic characteristics, menstruation, parity and UI symptoms was collected using a questionnaire. The data were evaluated by Chi-square test and multiple Logistic regression analysis. The prevalence rate of UI was 37.2%, with stress UI (32.2%) being more prevalent than urgency UI (21.6%) and mixed UI (16.6%). 31.2% women with UI stated that UI had negative impact on their life. Risk factors for UI included menstrual disorder, menopause, overweight, perineal laceration, atrophic vaginitis, constipation and pelvic organ prolapse. Appropriate investigation apropos the factors associated with UI should be performed to diminish its impact on women's life.
