Objective: To explore the relationship between beverage dependence and sleep quality among college students, providing empirical evidence for improving their sleep quality. Methods: From December 2024 to January 2025, a convenience sampling method was used to conduct a questionnaire survey among 3 974 college students from four universities in Anhui Province. The Beverage Addiction Scale for College Students (BASCS) was used to assess beverage dependence, and the Self rating Scale of Sleep(SRSS) was used to evaluate sleep quality. A multivariate Logistic regression model was employed to analyze the relationship between beverage dependence and sleep quality, and a restricted cubic spline model was used to examine the dose response relationship between the two. Results: The positive rate of beverage dependence symptoms among college students was 7.6%, with positive rates of 9.6%, 13.8%, and 7.4% for the withdrawal symptoms, health effects, and dependence symptoms dimensions, respectively. The detection rate of sleep disorders was 23.6%. Multivariate Logistic regression analysis showed that after adjusting for covariates such as grade, gender, and body mass index, compared with the no beverage dependence group, students with positive beverage dependence symptoms had a higher risk of sleep disorders( OR =3.71, 95% CI =2.87-4.80, P <0.01). The OR (95% CI ) for sleep disorders among students with positive symptoms in the withdrawal symptoms, health effects, and dependence symptoms dimensions were 2.80(2.22-3.53), 2.38(1.95-2.91), and 2.45(1.89-3.18)(all P <0.01). Further analysis using a restricted cubic spline model revealed that the overall beverage dependence score and its three dimensional scores were approximately linearly related to the risk of sleep disorders among college students (all nonlinear P >0.05). Conclusions Beverage dependence is associated with sleep quality among college students. Schools should take multiple approaches, such as health education on beverage awareness, to improve students sleep quality.

Objective To investigate the effects and underlying mechanisms of a spray prepared from exosomes derived from M2 macrophages induced by interleukin-4 （IL-4） and tantalum particles （Ta） on the healing of pressure ulcers. Methods Bone marrow-derived macrophages were polarized into M2 macrophages using IL-4 or Ta, and exosomes （Exo-IL-4/Exo-Ta） were extracted. The regulatory effects of Exo-IL-4/Exo-Ta on M1 macrophage phenotypes and fibroblast matrix secretion were evaluated in vitro. Proteomic analysis was conducted to explore the biological processes and regulatory networks associated with Exo-Ta. A rat pressure ulcer model was used to assess the effects of Exo-IL-4/Exo-Ta spray on wound healing rate, inflammatory cell infiltration, and collagen deposition. Results In vitro, Exo-IL-4/Exo-Ta induced the polarization of M1 macrophages to M2 macrophages, reduced the secretion of pro-inflammatory factors, and promoted the expression of anti-inflammatory substances. Additionally, Exo-IL-4/Exo-Ta enhanced the production of collagen and fibronectin in fibroblasts. Proteomic analysis revealed that Exo-Ta primarily participated in biological processes such as energy metabolism and macromolecule biosynthesis. In vivo, Exo-IL-4/Exo-Ta spray accelerated wound healing, reduced inflammatory infiltration, and improved tissue remodeling in the rat pressure ulcer model. Conclusion Exosome sprays derived from M2 macrophages could accelerate pressure ulcer healing by modulating inflammation and promoting tissue regeneration, which demonstrated excellent clinical application potential.

Objective To compare the effects of three kinds of artificial hydronephrosis in percutaneous nephrolithotomy.Methods A total of 120 patients who underwent single-tract percutaneous nephrolithotomy in the Eighth Hospital of Wuhan from May 2020 to April 2022 were selected and divided equally into three groups according to different methods of artificial hydronephrosis.Patients in group A were received preoperative indwelling ureteral catheter and injection of normal saline through ureteral catheter to dilate renal pelvis and form artificial hydronephrosis.Patients in Group B were placed with double J catheters before surgery,and the bladder was filled with physiological saline through the catheter.The renal pelvis was dilated through the double J catheters,resulting in artificial hydronephrosis.Patients in Group C were received intravenous injection of furosemide and stimulated diuretic method to actively dilate renal pelvis to form hydronephrosis.The one-time puncture success rate,channel establishment time,overall operation time,stone clearance rate and incidence of surgical complications of percutaneous nephrolithotomy after hydronephrosis were compared among the three groups.Results The operation was successfully completed in the three groups.There was no significant difference in the one-time puncture success rate and channel establishment time between group A and group B(P>0.05),which were all higher than group C(P<0.05).The overall operation time of group B was shorter than that of group A and group C(P<0.05).There were no significant differences in stone clearance rate and surgical complications among the three groups(P>0.05).Conclusion Preoperative indwelling of double J tubes to create artificial kidney hydronephrosis has advantages such as high success rate of one-time puncture,short channel establishment time,and surgical time.

Objective:To compare and evaluate recurrence patterns after robotic-assisted gastrectomy (RAG) versus laparoscopic-assisted gastrectomy (LAG).Methods:This was a retrospective cohort study of 2915 consecutive patients with gastric adenocarcinoma confirmed by postoperative histology as T1-4aN0-3M0, who had undergone minimally invasive radical gastrectomy at four large gastric cancer treatment centers (Fujian Medical University Union Hospital: 1426 patients; the First Affiliated Hospital, Nanchang University: 1108; Tianjin Medical University Cancer Institute and Hospital: 196; and First Affiliated Hospital of Xi'an Jiaotong University: 185 cases) between 1 January 2015 and 30 June 2019. 930 patients had undergone RAG (RAG group) and 1985 had undergone LAG (LAG group). We assessed the following characteristics: age, sex, body mass index, American Society of Anesthesiologists score, comorbidities, tumor size, extent of surgery, extent of lymph node dissection, pT, pN, year of surgery, and adjuvant chemotherapy, after propensity score matching (1:1). There were no significant differences in baseline clinical characteristics between the two groups formed by propensity score matching (837 in each group) (all P>0.05). The 3-year recurrence-free survival (RFS), recurrence pattern, and conditional RFS were compared. Results:We detected no significant differences in the overall recurrence rate at 3 years (128/837 [15.3%] vs. 141/837 [16.8%], P=0.387) or time to recurrence (15.7±8.1 months vs. 16.4±8.4 months, P=0.449) between the RAG and LAG groups. Peritoneal recurrence was the most common type of recurrence in both groups (55 [6.6%] vs. 69 [8.2%], P=0.524). The difference in 3-year RFS between the RAG and LAG groups was not statistically significant (83.2% vs. 82.5%, P=0.781). We found that age > 60 years, total gastrectomy, and worse pT stage and pN stage were independent risk factors for recurrence in the study patients (all P<0.05), whereas the surgical procedure (RAG or LAG) was not an independent risk factor for RFS ( P=0.242). The 3-year conditional RFS at various time points was comparable between the two groups (1 year postoperatively: 84.6% vs. 84.7%, P=0.793; 3 years postoperatively: 91.5% vs. 94.9%, P=0.647). Conclusions:In this multicenter study of patients with locally resectable gastric cancer, we demonstrated that RAG performed by surgeons at large gastric cancer centers is not inferior to LAG in 3-year recurrence rate or recurrence patterns.

Objective To investigate the impact of hemoglobin(Hb)level on the risk of all-cause mortality in elderly patients with stable coronary artery disease(SCAD)treated by percutaneous coronary intervention(PCI).Methods A retrospective cohort study was conducted on 195 elderly SCAD patients treated by PCI in our hospital from June 2016 to December 2017,a total of 180 case were followed up.They were divided into four groups based on quartiles of Hb levels:Q1 group[≤122(108.28±12.53)g/L,n=47],Q2 group[122＜Hb≤137(130.07±4.33)g/L,n=43],Q3 group[137＜Hb≤148(142.67±3.10)g/L,n=46],and Q4 group[＞148(158.36±8.50)g/L,n=44].Their clinical data were collected and compared among the groups.All patients were followed up,with all-cause mortality as endpoint.Cox regression analysis was used to evaluate the impact of Hb level on all-cause mortality in elderly SCAD patients treated by PCI.Results For the 180 patients with complete follow-up,the median follow-up time was 703(415,1121)d,and the incidence of all-cause mortality was 10.00％(totally 18 deaths).And the incidence was 25.50％(12 deaths),7.00％(3 death),4.30％(2 deaths)and 2.30％(1 death)in Q1,Q2,Q3,and Q4 groups,respectively,with statistically significant differences(P＜0.01).Univariate Cox regression analysis showed age was a risk factor for all-cause death(P＜0.01),while Hb level,BMI,smoking history,dyslipidemia,and aspirin use were a risk facotr for all-cause death(P＜0.05,P＜0.01).Further multivariate Cox regression analysis revealed Hb level was a risk facotr for all-cause death(HR=0.96,95％CI:0.93-0.99,P＜0.01).The risk of all-cause mortality was 3.68 times higher in the Q1 group than the Q2 group(HR=3.68,95％CI:1.01-13.45,P＜0.05),and there was no correlation in the incidence between the Q3 and Q4 groups(P＞0.05).Conclusion Low Hb level is an independent predictor for all-cause mortality in elderly SCAD pa-tients after PCI.

Objective:To study the clinical value of serum microRNA-34a (miR-34a) and aryl hydrocarbon receptor nuclear transcript-like protein 1 (BMAL1) in cervical cancer and their relationship with high-risk human papillomavirus (HR-HPV) infection.Methods:The clinical data of 76 patients with cervical cancer and 50 patients with benign cervical diseases in the Affiliated Hospital of Jining Medical University from January to December 2022 were retrospectively analyzed. The expression levels of serum miR-34a and BMAL1 were detected by real-time fluorescence quantitative polymerase chain reaction, and HR-HPV infection was detected by flow fluorescent hybridization. The patients were followed up until December 2023, and the death and poor prognosis (death, tumor recurrence and progression and severe complications at 1-year of follow-up) were recorded. The receiver operating characteristic (ROC) curve was used to analyze the efficacy of miR-34a, BMAL1 and related indexes in evaluating the poor prognosis in patients with cervical cancer at 1-year. Multivariate Cox regression analysis was used to analyze the independent risk factors for death in patients with cervical cancer. The Kaplan-Meier survival curve was used to analyze the relationship between miR-34a, BMAL1 expression and survival period, and the log-rank test was used for comparison.Results:The expression level of serum miR-34a in patients with cervical cancer was significantly lower than that in patients with benign cervical lesions (0.46 ± 0.08 vs. 0.67 ± 0.11), the expression level of serum BMAL1 was significantly higher than that in patients with benign cervical lesions (0.58 ± 0.07 vs. 0.41 ± 0.07), and there were statistical differences ( t= 12.40 and 13.34, P<0.01). The expression levels of serum miR-34a and BMAL1 in patients with cervical cancer were associated with tumor differentiation, myometrial invasion depth, lymph node metastasis, distant metastasis and International Federation of Gynecology and Obstetrics (FIGO) stage, and there were statistical differences ( P<0.05 or<0.01); they were not associated with age, menopause and pathological type, and there were no statistical differences ( P>0.05). In patients with cervical cancer, the expression level of miR-34a in patients with HR-HPV positive infection (60 cases) was significantly lower than that in patients with HR-HPV negative infection (16 cases): 0.41 ± 0.07 vs. 0.49 ± 0.08, the expression level of BMAL1 was significantly higher than that in patients with HR-HPV negative infection: 0.65 ± 0.09 vs. 0.53 ± 0.06, and there were statistical differences ( t = 3.68 and 4.24, P<0.05 or<0.01). In patients with benign cervical diseases, there were no statistical differences in the expression levels of miR-34a and BMAL1 between patients with HR-HPV positive infection (7 cases) and patients with HR-HPV negative infection (43 cases) ( P>0.05). ROC curve analysis result showed that miR-34a combined with BMAL1 had the highest sensitivity (90.4%), specificity (89.9%) and area under curve (0.911) in assessing the 1-year poor prognosis in patients with cervical cancer ( P<0.01), and the optimal cutoff values of miR-34a and BMAL1 expression level were ≤0.39 and ≥0.64. Multivariate Cox regression analysis result showed that poor differentiation, myometrial invasion depth ≥1/2, lymph node metastasis, distant metastasis, FIGO stage Ⅲ+Ⅳ, miR-34a expression level ≤0.46 and BMAL1 expression level ≥0.58 were independent risk factors for death in patients with cervical cancer ( OR = 1.857, 2.125, 2.337, 2.751, 2.457, 3.885 and 3.666; 95% CI 0.845 to 5.788, 0.726 to 5.924, 0.709 to 5.631, 0.693 to 5.727, 0.801 to 5.936, 1.244 to 6.423 and 1.031 to 5.612; P<0.01). Kaplan-Meier survival curve analysis result showed that the median survival time in cervical cancer patients with miR-34a expression level ≤0.39 and BMAL1 expression level ≥0.64 (21 cases) was significantly lower than that in the other cervical cancer patients (miR-34a expression level>0.39 or BMAL1 expression level<0.64, 55 cases): (26.4 ± 4.2) months vs. (34.2 ± 5.6) months, log-rank χ2 = 17.12, P<0.05. Conclusions:The expression level of serum miR-34a in patients with cervical cancer is significantly reduced and the expression level of BMAL1 is significantly increased, which is related to the condition, prognosis and HR-HPV infection. It can be used as a marker for the assessment of the condition and prognosis of cervical cancer. The combined detection of the two can significantly improve the sensitivity and specificity in predicting poor prognosis of cervical cancer.

With the rapid increase in the prevalence rate of nonalcoholic fatty liver disease (NAFLD), new treatment methods are needed to prevent disease progression to liver fibrosis, liver cirrhosis, and liver cancer. Although great efforts have been made to clarify the pathological mechanisms of NAFLD disease progression, there are still no effective treatment methods at present. Bile acids (BAs) regulate systemic metabolism by activating nuclear receptors and G protein-coupled receptors and have been identified as important signaling molecules involved in lipid, glucose, and energy metabolism. Dysregulation of BA homeostasis is associated with the severity of NAFLD. This article summarizes the important ligands in BA metabolism and their role in the progression of NAFLD, in order to provide a basis for the treatment of NAFLD by targeting BA messengers.

Objective:To explore the technical points and efficacy of gradual traction-unlocking closed reduction technique (GT-UCRT) for Tile C old pelvic fractures.Methods:From August 2012 to June 2021, 6 patients with Tile C old pelvic fracture were treated and followed up at Department of Orthopedics, The Fourth Medical Center, General Hospital of Chinese PLA. They were 4 males and 2 females with an age of (35.8±10.5) years. By Tile classification: 4 cases of type C1.2, 1 case of type C1.3, and 1 case of type C2; time from injury to surgery: 153.8 (64.3, 204.8) days. The 6 patients were treated with GT-UCRT. The time for gradual traction reduction, operation time, hospital stay, intraoperative blood loss and complications were recorded. The modified Matta score was used to evaluate the reduction quality of pelvic fractures, and the Majeed score was used to evaluate the pelvic function at the last follow-up.Results:The 6 patients were followed up for (40.3±22.9) months (from 12 to 72 months) after surgery. The time for gradual traction reduction was (26.7±4.6) days, operation time (119.2±4.6) minutes, hospital stay (11.5±2.9) days, and intraoperative blood loss (533.3±189.6) mL. By the modified Matta score, the pelvic reduction after surgery was rated as satisfactory in 5 cases and as unsatisfactory in 1 case. The length disparity between both lower limbs in the 6 patients was (6.9±1.6) cm before surgery and (1.0±0.4) cm immediately after surgery, showing a statistically significant difference ( t=11.135, P<0.001). One fracture healed 3 months after surgery and 5 fractures 6 months after surgery. The Majeed pelvic score at the last follow-up was (80.8±9.0) points for the 6 patients, yielding 2 excellent cases, 3 good cases and 1 fair case. Delayed wound healing was reported in 1 patient, calf intermuscular venous thrombosis in 2 cases, and emotional anxiety and sleep disorder in 1 patient. No new lumbosacral plexus injury was found in any patient. Conclusions:In the treatment of Tile C old pelvic fractures, since our self-designed GT-UCRT combines the advantages of Ilizarov technique and unlocking closed reduction technique, it can not only protect the lumbosacral plexus but also obtain satisfactory reduction of the fracture.

Objective:To investigate the clinical value of magnetic resonance imaging (MRI) based integrated deep learning model for predicting the times of linear staplers used in double stapling technique for middle-low rectal cancer resection.Methods:The retrospective cohort study was conducted. The clinicopathological data of 263 patients who underwent low anterior resection (LAR) for middle-low rectal cancer in Ruijin Hospital of Shanghai Jiaotong University School of Medicine from January 2018 to December 2022 were collected as training dataset. There were 183 males and 80 females, aged 63(55,68)years. The clinicopathological data of 128 patients with middle-low rectal cancer were collected as validation dataset, including 83 males and 45 females, with age as 65(57,70)years. The training dataset was used to construct the prediction model, and the validation dataset was used to validate the prediction model. Observation indicators: (1) clinicopathological features of patients in the training dataset; (2) influencing factors for ≥3 times using of linear staplers in the operation; (3) prediction model construction; (4) efficiency evaluation of prediction model; (5) validation of prediction model. Measurement data with skewed distribution were represented as M( Q1, Q3), and Mann-Whitney U test was used for comparison between groups. Count data were expressed as absolute numbers, and comparison between groups was conducted using the chi-square test. Wilcoxon rank sum test was used for non-parametric data analysis. Univariate analysis was conducted using the Logistic regression model, and multivariate analysis was conducted using the Logistic stepwise regression model. The receiver operating characteristic (ROC) curve was draw and the area under the curve (AUC) was calculated. The AUC of the ROC curve >0.75 indicated the prediction model as acceptable. Comparison of AUC was conducted using the Delong test. Results:(1) Clinicopathological features of patients in the training dataset. Of the 263 patients, there were 48 cases with linear staplers used in the operation ≥3 times and 215 cases with linear staplers used in the operation ≤2 times. Cases with preoperative serum carcinoembryonic antigen (CEA) >5 μg/L, cases with anastomotic leakage, cases with tumor diameter ≥5 cm were 20, 12, 13 in the 48 cases with linear staplers used ≥3 times in the operation, versus 56, 26, 21 in the 215 cases with linear staplers used ≤2 times in the operation, showing significant differences in the above indicators between them ( χ2=4.66, 5.29, 10.45, P<0.05). (2) Influencing factors for ≥3 times using of linear staplers in the operation. Results of multivariate analysis showed that preoperative serum CEA >5 μg/L and tumor diameter ≥5 cm were independent risk factors for ≥3 times using of linear staplers in the operation ( odds ratio=2.26, 3.39, 95% confidence interval as 1.15-4.43, 1.50-7.65, P<0.05). (3) Prediction model construction. According to the results of multivariate analysis, the clinical prediction model was established as Logit(P)=-2.018+0.814×preoperative serum CEA (>5 μg/L as 1, ≤5 μg/L as 0)+ 1.222×tumor diameter (≥5 cm as 1, <5 cm as 0). The image data segmented by the Mask region convolutional neural network (MASK R-CNN) was input into the three-dimensional convolutional neural network (C3D), and the image prediction model was constructed by training. The image data segmented by the MASK R-CNN and the clinical independent risk factors were input into the C3D, and the integrated prediction model was constructed by training.

The sensitivity, specificity and accuracy of the image prediction model was 50.0%, 98.3% and 91.2%, respectively, with the Yoden index as 0.48. The sensitivity, specificity and accuracy of the integrated prediction model was 70.0%, 98.3% and 94.1%, respectively, with the Yoden index as 0.68. The AUC of clinical prediction model, image prediction model and integrated prediction model was 0.72(95% confidence interval as 0.61-0.83), 0.81(95% confidence interval as 0.71-0.91) and 0.88(95% confidence interval as 0.81-0.95), respectively. There were significant differences in the efficacy between the integrated prediction model and the image prediction model or the clinical prediction model ( Z=2.98, 2.48, P<0.05). (5) Validation of prediction model. The three prediction models were externally validated by validation dataset. The sensitivity, specificity and accuracy of the clinical prediction model was 62.5%, 66.1% and 65.6%, respectively, with the Yoden index as 0.29. The sensitivity, specificity and accuracy of the image prediction model was 58.8%, 95.5% and 92.1%, respectively, with the Yoden index as 0.64. The sensitivity, specificity and accuracy of the integrated prediction model was 68.8%, 97.3% and 93.8%, respectively, with the Yoden index as 0.66. The AUC of clinical prediction model, image prediction model and integrated prediction model was 0.65(95% confidence interval as 0.55-0.75), 0.75(95% confidence interval as 0.66-0.84) and 0.84(95% confidence interval as 0.74-0.93), respec-tively. There was significant differences in the efficacy between the clinical prediction model and the integrated prediction model ( Z=3.24, P<0.05). Conclusion:The MRI-based deep-learning model can help predicting the high-risk population with ≥3 times using of linear staplers in resection of middle-low rectal cancer with double stapling technique.
