Objective To evaluate the efficacy of combining surgical treatment with biological agents for perianal fistulizing Crohn's disease(pfCD).Methods Sixty patients with perianal fistulizing Crohn's disease(pfCD)admitted to our hospital from May 2021 to December 2023 were randomly allocated into two groups:Treatment Group A(n=30)and Treatment Group B(n=30).Treatment Group A received pfCD surgery combined with inflix-imab(IFX)and azathioprine(AZA),while Treatment Group B underwent pfCD surgery along with ustekinumab(UST)and AZA.The CDAI score,PDAI score,and Assche score were monitored for both groups,and postoperative MRI examinations were conducted to evaluate the healing of pfCD.Results There were statistically significant differences in CDAI,PDAI,and Assche scores between pre-treatment and post-treatment comparisons within treat-ment groups A and B(P<0.05),as well as in the magnitude of change at each time point.Comparisons of CDAI,PDAI,and Assche scores at 8,16,24,and 32 weeks,and PDAI scores at 40 weeks between groups A and B using independent samples t-tests did not yield statistically significant results(P>0.05).However,significant differences were observed for CDAI and Assche scores at 40 weeks(P<0.05).Significant changes in CDAI,PDAI,and Assche scores were noted at 8,16,24,32,and 40 weeks post-treatment within both groups A and B(P<0.05).Multiple comparisons using the LSD method revealed that the changes in these scores at each time point were statistically significant(P<0.05).The data indicate a temporal trend in the changes of CDAI,PDAI,and Assche scores,with group B showing a more rapid decline compared to group A.In terms of fistula response rates,both groups A and B achieved 100%(30/30).However,the clinical healing rate of fistulas was higher in group B at 86.7%(26/30)compared to 76.7%(23/30)in group A.Conclusion The combination of surgical treatment with IFX/UST plus AZA is safe and effective for treating pfCD.However,the long-term efficacy of combining surgical treatment with UST appears to be superior.

Objective:To assess the association between possible sarcopenia and the risk for frailty in middle-aged and elderly adults in China.Methods:A prospective cohort study design was used in this study. Data were from the China Health and Retirement Longitudinal Study during 2011-2018 and the baseline data in 2011, the follow up was conducted in 2013, 2015 and 2018, respectively. Frailty index was used to evaluate frailty status, and grip strength and repetitive sitting-up time were measured to detect possible sarcopenia. Cox proportional hazards regression model was used to estimate the association between possible sarcopenia and the risk for frailty in middle-aged and older adults.Results:In a 44 884 person-years follow-up, a total of 586 cases with frailty were recorded, and the incidence density of frailty was 13.06 per 1 000 person-year. The risk for frailty was also higher in those who were aged 60 years and above ( HR=2.05, 95% CI: 1.71-2.45), had a primary school education level or below ( HR=1.55, 95% CI: 1.29-1.85), had waist-to-height ratio ≥0.5 ( HR=1.39, 95% CI: 1.11-1.75) and had depression ( HR=1.52, 95% CI: 1.28-1.81). Drinking was associated with reduced risk for frailty ( HR=0.76, 95% CI: 0.62-0.94). The risk for frailty increased ( HR=1.73, 95% CI: 1.47-2.05) in those who might has possible sarcopenia. Conclusions:In middle-aged and elderly adults, those with possible sarcopenia, lower education level, central obesity and depression might be at high risk for frailty, and early interventions for high-risk population can be taken to slow the progression of frailty.

Objective:To explore the application effect of phased target teaching combined with case teaching method in neurosurgery intern nurses.Methods:A convenient sampling method was used to select 96 intern nurses in the neurosurgery department of Shandong Provincial Hospital Affiliated to Shandong First Medical University from January 2022 to December 2023. The participants were divided into a control group and an observation group. The control group received conventional teaching, while the observation group was given phased target teaching combined with case teaching method based on the control group's curriculum. The clinical work ability, critical thinking ability, teaching performance, teaching satisfaction and cooperation of the intern nurses in both groups were compared.Results:After the intervention, the observation group scored higher in clinical work ability, critical thinking ability, teaching satisfaction and cooperation, teaching performance compared to the control group ( P<0.05) . Conclusions:The application of phased target teaching combined with case teaching method for neurosurgery intern nurses can improve their clinical work ability, critical thinking ability, academic performance, teaching satisfaction and cooperation. This method is worth recommending.

Objective:To explore the association of central obesity, pain, their joint effect, and interaction with frailty in middle-aged and old people in China.Methods:A total of 14 359 participants aged ≥45 years in 2011, 2013 and 2015 were selected from the China Health and Retirement Longitudinal Study to construct a cohort database. Cox proportional hazards regression models were used to estimate the association of waist-to-height ratio (WHtR) and pain with the risk for frailty. Joint effect and interaction analyses were performed.Results:In the follow-up of 77 783 person-years, frailty developed in 3 198 participants, with an incidence density of 41.11 per 1 000 person-years. Compared with the Q1 level of WHtR, its Q2, Q3 and Q4 level increased risk for frailty by 17% ( HR=1.17, 95% CI: 1.05-1.31), 24% ( HR=1.24, 95% CI: 1.11-1.40), and 43% ( HR=1.43, 95% CI: 1.25-1.63), respectively. Compared with painlessness, suffering from pain increased the risk for frailty by 97% ( HR=1.97, 95% CI: 1.83-2.11), and having 1, 2, and ≥3 pain sites increased the risk by 42% ( HR=1.42, 95% CI: 1.25-1.61), 86% ( HR=1.86, 95% CI: 1.64-2.11), and 138% ( HR=2.38, 95% CI: 2.18-2.60), respectively. The results of restricted cubic spline showed that WHtR level was associated with the risk for frailty in a J-type dose-response relationship (total P<0.001, nonlinear P<0.001), and pain quantity was positively associated with the risk in a nonlinear dose-response relationship (total P<0.001, nonlinear P<0.001). Threshold effect analysis revealed that the inflection points of WHtR and pain site number were 0.46 and 2.00, respectively ( P<0.001). Joint effect analysis showed that the Q2, Q3 and Q4 levels of WHtR combined with pain increased the risk for frailty by 146% ( HR=2.46, 95% CI: 2.11-2.87), 169% ( HR=2.69, 95% CI: 2.30-3.16), and 157% ( HR=2.57, 95% CI: 2.18-3.03). Conclusions:The risk for frailty increased with the level of WHtR and the number of pain sites in middle-aged and old people, and there was joint effect between WHtR and pain. Comprehensive management and intervention of obesity and pain are significant for the early prevention of frailty.

Objective To screen out the indexes of medical insurance fund under China Healthcare Security Diagno-sis Related Groups(CHS-DRG)payment based on Delphi method and improve the efficiency of medical insurance fund supervision.Methods Using the Delphi method,32 experts in the medical insurance field were selected and 2 rounds of expert questionnaires were conducted to design an evaluation scale for the monitoring indicators of medi-cal insurance funds under CHS-DRG payment.The consultation results were evaluated from three aspects of motiva-tion,authority,and coordination.Results A medical insurance fund supervision index system based on three dimen-sions of medical insurance fund use quality,efficiency and safety supervision is constructed,including 3 first-level indicators,7 second-level indicators and 44 third-level indicators.Results The construction ofmedical insurance fund supervision index system under CHS-DRG payment should respect the actual clinical diagnosis and treatment,strengthen the intelligent supervision method,and timely intervene in medical insurance fund management risks.

Objective To assess the situation and influencing factors of occupational burnout among the staff at the Center for Disease Control and Prevention (CDC) in Sichuan Province. Methods A total of 1 038 CDC staff members in Sichuan Province were selected as the study subjects using the stratified random sampling method. Occupational burnout of the staff was assessed using the Maslach Burnout Inventory General Survey via an online questionnaire. Results The detection rate of occupational burnout was 42.3% (439/1 038). Binary logistic regression analysis result showed that, after controlling for confounding factors such as education level and alcohol consumption, CDC staffs aged at 20-<31, 31-<41, and 41-<51 years were at higher risk of occupational burnout compared with those ≥51 years (all P<0.05). CDC staffs with 5-<10 or ≥10 years of service had higher occupational burnout risk compared with those with <5 years (both P<0.05). CDC staffs with poor or fair health status, irregular diet, and poor sleep quality had higher risk of occupational burnout compared with those healthy, have regular diet, and good sleep quality (all P<0.05). The risk of occupational burnout increased with higher overtime frequency (all P<0.05). Conclusion Occupational burnout among CDC staffs in Sichuan Province is relatively high. Age, years of service, health status, diet, sleep quality, and overtime frequency are key influencing factors.

Objective: To investigate the trend in disease burden of diabetes mellitus among population aged 15 to 39 years in China from 1990 to 2021. Methods: Data on the incidence, prevalence, mortality, and disability-adjusted life year (DALY) rate of diabetes mellitus among population aged 15 to 39 years in China from 1990 to 2021 were collected from the Global Burden of Disease Study 2021 database. The disease burden of diabetes mellitus was analyzed by gender and age. The trend in disease burden among population aged 15 to 39 years was analyzed by average annual percent change (AAPC). Results: The incidence, prevalence and DALY rate of diabetes mellitus increased from 142.63/100 000, 1 826.41/100 000, and 138.04/100 000 in 1990 to 287.68/100 000, 5 245.93/100 000, and 316.82/100 000 in 2021, respectively, showing significant upward trends (AAPC=2.313%, 3.502% and 2.734%, all P<0.05). In contrast, the mortality decreased from 0.67/100 000 in 1990 to 0.57/100 000 in 2021, demonstrating a significant downward trend (AAPC=-0.518%, P<0.05). From 1990 to 2021, the incidences (AAPC=2.404% and 2.160%), prevalences (AAPC=3.576% and 3.389%), and DALY rates (AAPC=2.936% and 2.454%) of diabetes mellitus among males and females showed upward trends (all P<0.05). The mortality among females demonstrated a downward trend (AAPC=-1.809%, P<0.05), while the trend among males was not statistically significant (P>0.05). In 2021, the age group of 20 to <25 years had a relatively high incidence of diabetes mellitus, at 525.57/105. From 1990 to 2021, the incidences (AAPC=4.064%, 3.828%, 1.757%, 1.026% and 0.810%), prevalences (AAPC=2.374%, 3.625%, 3.371%, 2.985% and 2.647%), and DALY rates (AAPC=1.045%, 2.723%, 2.787%, 2.289% and 1.876%) of diabetes mellitus in age groups of 15 to <20 years, 20 to <25 years, 25 to <30 years, 30 to <35 years, and 35 to 39 years showed upward trends (all P<0.05). Conversely, the mortality (AAPC=-2.480%, -1.164%, -0.724%, -0.979% and -1.139%) in these age groups demonstrated downward trends (all P<0.05). Conclusion The overall disease burden of diabetes mellitus among population aged 15 to 39 years in China showed an upward trend, with males and the age group of 20 to <25 years being key target populations for diabetes mellitus prevention and control.

Pectus excavatum (PE) is a common congenital chest malformation in children, manifested by inward depression of the anteriorthorax wall, which can compress the normal tissues and organs in the chest and cause adverse effects on the physiology and psychology of patients. Surgery is the most important means of treating PE, and with the invention of Nuss surgery, the surgical treatment of PE has entered the minimally invasive era. At present, there are many indexes to evaluate the severity of thoracic malformations in PE patients, and selecting appropriate evaluation indexes is of great significance for the formulation of surgical protocols. As a physical and mental disease, PE's deformed thoracic appearance not only affects the function of thoracic organs, but also affects the psychological state of patients. Therefore, there is still controversy over whether the role of orthopedic surgery is to improve function or cosmetic plastic surgery. At the same time, the orthopedic efficacy and postoperative complications of the existing modified and novel surgical methods need to be further observed and evaluated. In addition, the design of surgical plan and the selection of surgical timing for PE combined with other diseases are also critical and controversial issues in clinical practice. Therefore, this article explores and reviews the controversial points in the current surgical treatment of PE.
