Objective To analyze the burden and trend of musculoskeletal diseases(including gout,low back pain,neck pain,osteoarthritis,and rheumatoid arthritis)in China from 1990 to 2021,and to provide reference for formulating and adjusting prevention strategies for musculoskeletal diseases.Methods The Global Burden of Disease(GBD)in 2021 database was used to analyze the status and trend of the incidence and disability-adjusted life years(DALYs)rate of musculoskeletal diseases in China.Annual percentage change(EAPC)was used to comprehensively evaluate the trend of the burden of musculoskeletal diseases from 1990 to 2021.Gender and age-specific incidence and DALYs rate of musculoskeletal diseases were analyzed.Results In 2021,the number of cases of gout,low back pain,neck pain,osteoarthritis,and rheumatoid arthritis in China was 3,079,836,43,374,995,10,292,099,11,652,721,and 247,307,respectively.Among the 5 major musculoskeletal conditions,low back pain had the greatest incidence and DALYs rate.From 1990 to 2021,the age-standardized incidence of gout,osteoarthritis,and rheumatoid arthritis showed an upward trend,that of neck pain remained relatively stable,and that of low back pain showed a downward trend.The age-standardized DALYs rates of gout and osteoarthritis showed an increasing trend,that of neck pain and rheumatoid arthritis remained relatively stable,and that of low back pain showed a decreasing trend.The results of the stratified analysis by gender and age indicated that,the age-standardized incidence rate and age-standardized DALYs rate of gout were higher in men than in women,while the age-standardized incidence rate and age-standardized DALYs rate of low back pain,neck pain,osteoarthritis,and rheumatoid arthritis were higher in women than in men.The age groups with the burden of the five major musculoskeletal diseases were relatively consistent,mainly in the 40-75 years old.Conclusion From 1990 to 2021,the disease burden of gout,osteoarthritis,and rheumatoid arthritis increased significantly in China,while the disease burden of neck pain remained relatively stable,while the disease burden of low back pain showed a certain improvement.In addition,the burden of musculoskeletal diseases in China varies greatly by gender and age.Targeted intervention measures should be implemented as soon as possible based on the stratification results by gender and age,and health education and basic healthcare should be improved to effectively reduce the burden of musculoskeletal diseases.

Objective:To compare surgery-related indicators, patient recovery status, perioperative complications and risk factors affecting the occurrence of postoperative grade Ⅲ or higher complications in patients undergoing laparoscopic gastric mesenchymal tumor surgery with different visceral fat areas.Methods:Clinical data of 116 patients with gastric interstitial tumor in Shaanxi Provincial People′s Hospital from April 2014 to June 2020 were retrospectively analyzed, including 44 male patients and 72 female patients, with patient aged from 25 to 88 years old and the mean age was (61.8±10.7) years, including 54 patients in the high VFA group and 62 patients in the low VFA group. SPSS 23.0 was used for statistical analysis, and t-test and χ2 test were applied to compare and analyze the patients′ surgery-related indexes, postoperative recovery status, complications within 30 d after surgery and differences in Clavien-Dindo classification of complications, while univariate and multifactorial analyses were used to study the factors affecting the occurrence of postoperative grade Ⅲ or higher complications. Results:Patients in the high VFA group had a higher body mass index than in the low VFA group, and the difference was statistically significant ( t=4.48, P<0.001); patients in the high VFA group had longer operative time ( t=2.88, P=0.005), more intraoperative bleeding ( t=2.17, P=0.032), longer period of fasting ( t=2.73, P=0.008), longer time for defecation ( t=4.46, P<0.001) and bowel movement ( t=4.62, P<0.001), and longer postoperative hospital stay ( t=3.43) compared with those in the low VFA group ( t=2.73, P=0.001), prolonged defecation ( t=4.46), prolonged bowel movement ( t=4.62), and prolonged postoperative hospitalization ( t=3.43), with statistically significant differences ( P<0.05); the incidence of postoperative complications was significantly higher in the high VFA group (31.4%) compared with the low VFA group (14.5%) ( χ2=4.78, P=0.029); among them, the incidence of postoperative pulmonary infection was significantly higher in patients in the high VFA group (12.9%) compared with those in the low VFA group (1.6%), and the difference between them was statistically significant ( χ2=4.16, P<0.05); while the differences in postoperative incision-related complications, anastomotic fistula, lower limb venous thrombosis, and intestinal obstruction were not statistically significant ( P>0.05). The incidence of postoperative complications above grade Ⅲ of the Clavien-Dindo complication classification was significantly higher in patients in the high VFA group (16.7%) compared with those in the low VFA group (4.8%), and the difference between the two was statistically significant ( χ2=4.35, P<0.05); univariate analysis revealed that operative time ≥300 min and increased VFA were the risk factors for postoperative grade Ⅲ or higher complications, while VFA was not an independent risk factor. Conclusion:Larger visceral fat area increases the difficulty of laparoscopic gastric mesenchymal tumor surgery operation, and also affects patients′ postoperative recovery, leading to increased postoperative complications, but VFA is not an independent risk factor affecting the occurrence of postoperative grade Ⅲ or higher complications in patients with gastric mesenchymal tumor.
