BACKGROUND: Parkinson's disease (PD) is a leading cause of death and disability worldwide, and is associated with a significant Global Burden of Disease (GBD). We analyzed the trends in PD incidence, mortality, and disability-adjusted life year (DALY) burden in China, and compared them with global data. METHODS: Estimates and 95% uncertainty intervals (UIs) for incidence, mortality, DALYs, years lived with disability (YLDs), and years of life lost (YLLs) for PD were extracted from the GBD, Injuries, and Risk Factors Study 2021. We describe the epidemiology of PD at global and Chinese levels, analyze trends in incidence and mortality from 1990 to 2021 by joinpoint regression models, and decompose PD burden according to population size, age structure, and epidemiological changes. RESULTS: GBD 2021 estimated 508,378 (95% UI: 430,499-592,748) incident cases of PD, 92,035 (95% UI: 75,908-108,133) deaths, and 2,159,514 (95% UI: 1,826,196-2,521,344) DALYs in China, with the higher age-standardized rate (ASR) in incidence, mortality and DALYs than the global levels. The DALY burden of PD in China increased slightly from 1990 to 2021, consistent with the global upward trend. Joinpoint regression analysis indicated that the ASR of incidence in China increased faster than the global average, while the ASR of mortality decreased, with the fastest decline in 2004-2014. Decomposition analysis revealed that men and the middle sociodemographic index (SDI) quintile (32.82%) were responsible for the most significant DALYs, whose changes were primarily driven by population growth and aging. CONCLUSIONS The burden of PD showed an overall increasing trend from 1990 to 2021, which was primarily driven by population growth and aging. This study highlights the significant challenges in controlling and managing PD, including the increase in cases and gender differences, which may provide guidance for comprehensive strategies to address the changing profiles of PD in China.

Parkinson′s disease is a common clinical degenerative disease of the nervous system, and rapid eye movement sleep behavior disorder (RBD) is a common sleep symptom of patients with Parkinson′s disease. This article reviews the pathogenesis, epidemiology, clinical characteristics, imaging manifestations, clinical evaluation and treatment of RBD in patients with Parkinson′s disease, in order to deepen the understanding of RBD in patients with Parkinson′s disease.

OBJECTIVETo study and establish the optimal technology for the preparation of evodiae juice.

METHODThe contents of evodiamine, rutaecarpine and evodin were simultaneously determined with HPLC, and each yield of the three compounds were chosen as the evaluating indicator. The orthogonal test coupled with the weighted coefficient method were adopted to acquire the optimal technology for the preparation of evodiae juice.

RESULTThe study showed that the optimal technology for the preparation of evodiae juice was as follows: decocted three times while the first time was with 12-fold of water socked 30 minutes and decocted 45 minutes, the second time was with 8-fold of water decocted 20 minutes and the third time was with 6-fold of water decocted 20 minutes.

CONCLUSIONThis method is simple and accurate. The optimal technology is suitable for industry manufacture of evodiae juice.
