Objective To analyze the disease burden of hip osteoarthritis(HOA)and its changing trends in China from 1990 to 2021.Methods Utilizing the Global Burden of Disease(GBD)2021 database,age-standardized incidence rate(ASIR),age-standardized prevalence rate(ASPR),and age-standardized disability adjusted life years(DALY)rate(ASDR)of HOA were compared and analyzed in China,globally,and in regions with high sociodemographic index(SDI)from 1990 to 2021.Joinpoint regression model was used to analyze the temporal trend of disease burden,and age and gender were combined to deeply analyze the disease burden of HOA in China.Meanwhile,the age-period-cohort model was used to analyze the influencing factors and the Bayesian age-period-cohort model to predict the trend of China's HOA disease burden in the next 10 years.Results The ASIR,ASPR,and ASDR of HOA in China showed an increasing trend from 1990 to 2021[average annual percentage change(AAPC)were 0.87％,0.82％,and 0.81％,respectively,P＜0.001],and their AAPCs were higher than those of the global and high SDI regions,but in 2021,the ASIR,ASPR,and ASDR of China were lower than those of the global and high SDI regions.Crude incidence,crude prevalence,and crude DALY rate in Chinese HOA increased with age,with the highest number of incidence in the 55-59 age group and the highest number of prevalence,DALY,in the 65-69 age group.In 2021,the ASIR,ASPR and ASDR of HOA in Chinese males were 1.25,1.24 and 1.25 times higher than those in females.Changes in the incidence of HOA in China from 1990 to 2021 were influenced by age,period,and birth cohort.Compared with 2021,new cases of HOA are expected to increase by 37.78％by 2035,and the number of incidence cases in people aged 60 years and above will increase significantly.Conclusion The disease burden of HOA in China continued to rise from 1990 to 2021,and prevention and control need to be strengthened,with a focus on men,high BMI,and middle-aged and older populations.

To promote the development of extracellular vesicles of herbal medicine especially the establishment of standardization, led by the National Expert Committee on Research and Application of Chinese Herbal Vesicles, research experts in the field of herbal medicine and extracellular vesicles were invited nationwide with the support of the Expert Committee on Research and Application of Chinese Herbal Vesicles, Professional Committee on Extracellular Vesicle Research and Application, Chinese Society of Research Hospitals and the Guangdong Engineering Research Center of Chinese Herbal Vesicles. Based on the collation of relevant literature, we have adopted the Delphi method, the consensus meeting method combined with the nominal group method to form a discussion draft of "Consensus statement on research and application of Chinese herbal medicine derived extracellular vesicles-like particles (2023)". The first draft was discussed in online and offline meetings on October 12, 14, November 2, 2022 and April and May 2023 on the current status of research, nomenclature, isolation methods, quality standards and research applications of extracellular vesicles of Chinese herbal medicines, and 13 consensus opinions were finally formed. At the Third Academic Conference on Research and Application of Chinese Herbal Vesicles, held on May 26, 2023, Kewei Zhao, convenor of the consensus, presented and read the consensus to the experts of the Expert Committee on Research and Application of Chinese Herbal Vesicles. The consensus highlights the characteristics and advantages of Chinese medicine, inherits the essence, and keeps the righteousness and innovation, aiming to provide a reference for colleagues engaged in research and application of Chinese herbal vesicles at home and abroad, decode the mystery behind Chinese herbal vesicles together, establish a safe, effective and controllable accurate Chinese herbal vesicle prevention and treatment system, and build a bridge for Chinese medicine to the world.
