OBJECTIVE: To analyze the disease burden of pelvic fractures at the global, regional, and national levels from 1990 to 2023 using data from the 2023 Global Burden of Disease Study (GBD), and to predict the disease burden through 2050. METHODS: Leveraging data from the GBD 2023, this study investigated the disease burden of pelvic fractures across 204 countries and regions. Assessment indicators included incidence rate, prevalence rate, and years lived with disability (YLDs). The Joinpoint regression model was employed to analyze trends in pelvic fracture burden from 1990 to 2023, while the average annual percentage change (AAPC) was used to quantify this temporal trend. The relationship between the socio-demographic index and pelvic fracture burden was evaluated. Furthermore, the long short-term memory (LSTM) model was applied to predict trends in pelvic fracture burden through 2050. RESULTS: In 2023, the estimated number of new pelvic fracture cases globally was 7 479 884 [95% uncertainty interval ( UI): 5 293 401-10 611 876], representing a 42.74% increase from 1990. In the same year, the number of prevalent pelvic fracture cases and YLDs were 23 007 508 (95% UI: 21 021 518-25 327 165) and 3 909 228 person-years (95% UI: 2 725 498-5 194 385), respectively. Additionally, age-standardized rates exhibited an opposing downward trend. Significant disparities in the disease burden of pelvic fractures were identified across different age groups, genders, and social contexts. According to predictions from the LSTM model, the global age-standardized incidence rate (ASIR) of pelvic fractures will be approximately 88.44 per 100 000 persons by 2050, while the total number of incident cases will rise to 8 547 095. CONCLUSION Although the overall incidence rate, prevalence rate, and YLDs of pelvic fractures have exhibited an upward trend over the past three decades, the ASIR, age-standardized prevalence rate (ASPR), and age-standardized years of life lost rate (ASYR) have shown a downward trend. It is predicted that over the upcoming 26-year period, the age-standardized rate of disease burden due to pelvic fractures will further decrease, while the number of incident cases and prevalent cases will continue to exhibit an upward trend. Formulating more targeted disease prevention strategies is critical to addressing disparities across genders, regions, and other dimensions, and to mitigating the burden of pelvic fractures.

Objective:To compare the clinical efficacy of autologous bone grafting or bioceramic bone grafting combined with locking compression plate (LCP) internal fixation in the treatment of Schatzker type II and III tibial plateau fractures.Methods:A retrospective analysis was conducted on 104 patients with Schatzker type II and III tibial plateau fractures who underwent surgical treatment at the Department of Orthopedics, PLA Central Theater Command General Hospital from January 2010 to December 2021. The cohort comprised 55 males and 49 females, with an average age of 49.13±13.80 years (range 18-73 years). All fractures were unilateral: 55 on the left and 49 on the right. According to the Schatzker classification, 59 were Type II and 45 were Type III. Causes of injury included traffic accidents (48 cases), falls from height (3 cases), sprains or falls (45 cases), and other causes (8 cases). During surgery, bioceramic material or allograft bone tissue was implanted into the collapsed tibial plateau region to restore articular surface flatness. Based on graft type, patients were divided into the allograft bone group (63 cases) and the bioceramic group (41 cases). All cases underwent proximal lateral tibial LCP internal fixation. The two groups were compared in terms of operative time, intraoperative blood loss, bone graft volume, length of hospital stay, fracture healing time, and postoperative complications. The Rasmussen radiographic collapse score was used to evaluate fracture reduction, and the Hospital for Special Surgery (HSS) score system was used to assess knee joint function.Results:All patients were followed up for 12(12, 13) months (range 12-16 months). The fracture healing time in the allograft bone group was 13.70±1.36 weeks (range 11-16 weeks), which was significantly shorter than that in the bioceramic group: 14.59±1.73 weeks (range 11-19 weeks) ( t=2.911, P=0.004). The time to full weight-bearing in the allograft group was 15.0(14.0, 17.0) weeks (range 13-23 weeks), which was shorter than the 16.0 (15.5, 18.5) weeks (range 12-24 weeks) in the bioceramic group, showing a statistically significant difference ( Z=-3.019, P=0.002). At 12 months postoperatively, the Rasmussen radiographic collapse score was 1(0, 1) in the bioceramic group, significantly lower than the 1(1, 2) score in the allograft group ( Z=-2.083, P=0.037). No statistically significant differences were observed between the two groups in bone graft volume, surgical duration, intraoperative blood loss, hospitalization duration, or HSS scores at 6 and 12 months postoperatively ( P>0.05). The complication rate was 6.3% (4/63) in the allograft group and 2.4% (1/41) in the bioceramic group, with no statistically significant difference (χ 2=0.830, P=0.362). Conclusions:For Schatzker type II and III tibial plateau fractures, the use of allograft bone or bioceramic combined with LCP internal fixation can achieve good results. Allograft bone has advantages in terms of fracture healing speed and early weight-bearing recovery, while bioceramic is more effective in maintaining joint surface stability.

Objective To establish a classification tree model for non-alcoholic fatty liver disease(NAFLD)among aircrews,screen for influencing factors of NAFLD,so as to provide scientific basis for prevention and intervention decisions for NAFLD.Methods Aircrews who underwent recuperation at a sanatorium from January 2019 to December 2023 were selected as the research objects.Their annual physical examination data were collected and the NAFLD detection rate was calculated.Age,body mass index(BMI),blood pressure,waist circumference,blood routine,biochemistry indexes,and thyroid function were incorporated,and a NAFLD risk model was constructed using classification regression tree method.The predictive performance of the NAFLD classification tree model was evaluated through model misclassification matrix,risk statistics,and receiver operating characteristic curve.Results A total of 4088 aircrews were included in the study,and NAFLD was detected in 380 persons(380/4088,9.30%).The NAFLD model consisted of three layers,and five explanatory variables affecting the onset of NAFLD were extracted,including BMI,triglycerides(TG),high-density lipoprotein cholesterol(HDL-C),alanine aminotransferase(ALT),and total bilirubin(TBIL).BMI was located at the top of the classification tree and was the most important risk factor for NAFLD in aircrews.The area under the curve(AUC)of the model was 0.853.The predictive accuracy of NAFLD was 90.9%,indicating that the model has good accuracy and fitting effect.Conclusion In this study,the detection rate of NAFLD in aircrews was 9.30%.BMI,TG,HDL-C,ALT,and TBIL are risk factors for the onset of NAFLD.NAFLD is mainly related to weight gain and lipid metabolism disorders caused by unhealthy lifestyles.

Objective To observe the mid-and long-term effects of Kegel training combined with Pilates training on urinary conti-nence recovery in different body mass index(BMI)male patients with urinary incontinence after prostatectomy.Methods From May,2023 to June,2024,48 patients in Beijing Bo'ai Hospital were recruited and divided into group A(<25 kg/m2,n=15),group B(25 to 30 kg/m2,n=18)and group C(>30 kg/m2,n=15)according to their BMI.All the groups performed Kegel training combined with Pilates training for two months,and followed up at six months from baseline.They were evaluated with one hour pad test,the number of daily urinary incontinence,In-ternational Consultation on Incontinence Questionnaire-Short Form(ICIQ-SF)and modified Oxford Rating Scale before treatment,and four weeks,eight weeks and six months after treatment.Results The intra-group effect,the inter-group effect and interaction effect were significant in the results of one hour pad test and the daily number of urinary incontinence(F>2.955,P<0.05).Post Hoc test showed that they were worse in group C than in groups A and B(P<0.05),and the number of daily urinary incontinence was more in group B than in group A(P<0.05).There was significant difference in the scores of ICIQ-SF and modified Ox-ford Rating Scale among groups in different time points after treatment(Z>10.476,P<0.05)except the score of ICIQ-SF four weeks after treatment(P>0.05),and they were the worst in group C.BMI(group A=1,group B=2,group C=3)was correlated with the results of one hour pad test(r=0.79,P<0.001),the number of daily uri-nary incontinence(r=0.68,P<0.001),and the scores of ICIQ-SF(r=0.68,P<0.001)and modified Oxford Rating Scale(r=-0.47,P=0.001)six months after treatment.Conclusion Kegel training combined with Pilates training could improve the urinary control in patients with urinary in-continence after prostatectomy.The decrease of BMI can promote the recovery of urinary control,and improve the symptoms of later urinary incontinence in mid-and long-term.

OBJECTIVE To evaluate the effictiveness and safety of recombinant human endostatin combined with afatinib and teggio in the treatment of advanced lung squamous cell carcinoma. METHODS A total of 25 patients with driver-negative advanced lung squamous cell carcinoma were included in this single-arm prospective study, and the enrolled patients were treated with recombinant human endostatin combined with afatinib and teggio as scheduled. Progression-free survival(PFS), overall survival(OS), disease control rate(DCR), objective response rate(ORR), and adverse reactions(AR) were observed and analyzed. RESULTS The 25 enrolled patients received at least 2 cycles of second-line treatment, and were followed up as of March 31, 2023. Among them, 4 patients had partial remission, 17 patients had stable disease, and 4 patients experienced progressive disease. The ORR confirmed by the researchers was 16%(95%CI, 4.5%−36.1%), DCR was 84%(95%CI, 63.9%−95.5%), and median PFS was 5.3 months(95%CI, 3.5−6.9 months). The median OS had not yet been achieved. The entire group of patients had good treatment tolerance, and the most common level Ⅲ or Ⅳ adverse events related to treatment were leukopenia(20%) and rash(12%), with no reported treatment-related deaths. CONCLUSION Recombinant human endostatin combined with afatinib and teggio in the second line treatment of advanced lung squamous cell carcinoma can prolong the progression free survival period of patients and is relatively safe, which is worth further exploration and promotion.

Objective Genotypes(G)1,3,and 5 of the Japanese encephalitis virus(JEV)have been isolated in China,but the dominant genotype circulating in Chinese coastal areas remains unknown.We searched for G5 JEV-infected cases and attempted to elucidate which JEV genotype was most closely related to human Japanese encephalitis(JE)in the coastal provinces of China. Methods In this study,we collected serum specimens from patients with JE in three coastal provinces of China(Guangdong,Zhejiang,and Shandong)from 2018 to 2020 and conducted JEV cross-neutralization tests against G1,G3,and G5. Results Acute serum specimens from clinically reported JE cases were obtained for laboratory confirmation from hospitals in Shandong(92 patients),Zhejiang(192 patients),and Guangdong(77 patients),China,from 2018 to 2020.Seventy of the 361 serum specimens were laboratory-confirmed to be infected with JEV.Two cases were confirmed to be infected with G1 JEV,32 with G3 JEV,and two with G5 JEV. Conclusion G3 was the primary infection genotype among JE cases with a definite infection genotype,and the infection caused by G5 JEV was confirmed serologically in China.

Objective:To investigate the application effects of nitrous oxide and oxygen mixed inhalation technology on analgesia and sedation during debridement and dressing change in children with moderate or severe burns.Methods:A retrospective non-randomized contemporary controlled study was conducted. From December 2019 to November 2021, 140 burn children with moderate or severe burns, aged 1 to 3 years, who met the inclusion criteria were admitted to Central Hospital Affiliated to Shandong First Medical University. During debridement and dressing change 3 to 14 days after injury, 42 children, including 23 males and 19 females, who received nurse-centered pain management mode and analgesia and sedation with nitrous oxide and oxygen mixed inhalation technology were included in nitrous oxide group (the dressing change process using the above-mentioned technology for the first time was selected for the follow-up study). Another 42 children, including 24 males and 18 females, were included in non-nitrous oxide group from 98 children who did not apply analgesia or sedation treatment during dressing change with stratified random sampling (one dressing change process was randomly selected for the follow-up study). The face, legs, activity, cry, and consolability scale and Ramsay sedation scale were used to evaluate the pain intensity and degree of sedation, respectively, at 30 minutes before dressing change (hereinafter referred to as before dressing change), immediately after debridement, and at 30 minutes after finishing dressing change (hereinafter referred to as after dressing change). After dressing change, the self-made satisfaction scale was used to evaluate the satisfaction degree of dressing change surgeons and guardians of children for analgesic effects during dressing change. The duration of dressing change and the healing time of deep partial-thickness burn wounds were recorded. The heart rate and percutaneous arterial oxygen saturation (SpO 2) before, during, and after dressing change and the occurrence of adverse events such as nausea and vomiting during dressing change were recorded. Data were statistically analyzed with Mann-Whitney U test, chi-square test, analysis of variance for repeated measurement, independent sample t test, and Bonferroni correction. Results:There were no significant differences in the score of pain intensity and score of sedation degree between children in two groups before and after dressing change ( P>0.05). Immediately after debridement, the score of pain intensity of children in nitrous oxide group was 2.5±0.7, which was significantly lower than 7.6±1.0 in non-nitrous oxide group ( t=-26.69, P<0.05); the score of sedation degree of children in nitrous oxide group was 1.83±0.38, which was significantly higher than 1.21±0.42 in non-nitrous oxide group ( t=7.15, P<0.05). After dressing change, the satisfaction degree scores of dressing change surgeons and guardians of children for analgesic effects during dressing change of children in nitrous oxide group were significantly higher than those in non-nitrous oxide group (with t values of 10.53 and 2.24, respectively, P<0.05). The dressing change duration of children in nitrous oxide group was significantly shorter than that in non-nitrous oxide group ( t=-5.33, P<0.05). The healing time of deep partial-thickness burn wounds in children between the two groups had no significant difference ( P>0.05). The heart rate of children in nitrous oxide group was significantly lower than that in non-nitrous oxide group during dressing change ( t=-12.40, P<0.05), while the SpO 2 was significantly higher than that in non-nitrous oxide group ( t=5.98, P<0.05). During dressing change, 2 children had nausea and 1 child had euphoria in nitrous oxide group, while heart rate of all children in non-nitrous oxide group continued to be higher than the normal range. Conclusions:In the process of debridement and dressing change in children with moderate or severe burns, the use of nurse-centered pain management mode and the standardized use of nitrous oxide and oxygen mixed inhalation technology can safely and effectively control pain and sedation.

【Objective】 To investigate the recurrence of patients with renal cell carcinoma (RCC) after robot-assisted partial nephrectomy (RAPN), and to explore the related factors of recurrence. 【Methods】 Clinical data of 367 RCC patients who underwent RAPN during 2015 and 2020 in our hospital were retrospectively collected. Patients were divided into recurrence group and non-recurrence group. The related factors of recurrence and 5-year cumulative recurrence rate of RCC and clear cell renal cell carcinoma (ccRCC) in the recurrence group were analyzed. 【Results】 The median follow-up was 48 (IQR:38-60) months. Recurrence occurred in 9 patients, with a 5-year cumulative recurrence rate of 97.5%. For RCC patients, univariate analysis showed that tumor size, T-stage, R. E. N. A. L. score, R value, N value, and operation time were significantly associated with postoperative recurrence (P<0.05), while multivariate analysis showed that N value (HR=15.75, 95%CI:2.00-124.17, P=0.009) was an independent related factor. For ccRCC patients, univariate analysis showed that hypertension, tumor size, T-stage, R. E. N. A. L. score, N value, operation time and WHO/ISUP grade were significantly associated with postoperative recurrence (P<0.05), while multivariate analysis showed that WHO/ISUP grade (HR=4.99, 95%CI:1.04-24.01, P=0.045) was an independent related factor. 【Conclusion】 The 5-year cumulative recurrence rate of RCC patients after RAPN is 2.5%. N value and WHO/ISUP grade are the independent related factor of recurrence of RCC and ccRCC, respectively.
