Background: Evaluating the impact of digestive system diseases is vital for devising effective prevention strategies. However, comprehensive reports on the burden of digestive system diseases in China are lacking. Our study aimed to provide an overview of the burden and trends of digestive system diseases from 1990 to 2019 in China and its ***: This cross-sectional study utilized the Global disease Burden Study 2019 to estimate the incidence, mortality rate, disability-adjusted life years (DALYs), years of life disability, years of life lost, and changes in the burden of digestive diseases across Chinese provinces from 1990 to 2019. The analysis of disease burden primarily examines the characteristics of sub-disease distribution, time trends, age distribution, and sex distribution. Additionally, we compared provincial age-standardized DALYs for digestive diseases with the expected rates based on the socio-demographic index (SDI).Results: In 2019, there were 499.2 million cases of digestive system diseases in China, resulting in 1,557,310 deaths. Stomach cancer, colon and rectal cancer, and esophageal cancer are the top three diseases associated with mortality and DALY related to digestive system diseases. Meanwhile, cirrhosis and other chronic liver diseases, gastroesophageal reflux disease, and gallbladder and biliary diseases are the top three kinds of diseases with the highest prevalence among digestive system diseases. The risk of gastric cancer sharply increases among men after the age of 40 years, leading to a significant disparity in burden between men and women. As the SDI increased, the DALYs associated with digestive system diseases in China and its provinces showed a downward ***: Our study highlights the inverse correlation between DALYs associated with digestive system diseases and the SDI.

Ursolic acid inhibiting excessive reticulophagic flux contributes to alleviate ochratoxin A-induced endoplasmic reticulum stress- and mitochondrial-mediated apoptosis

引用

Food Science and Human Wellness 2024年

作者： Huiqiong Deng Wenying Chen Lingyun Han Boyang Zhang Xun Luo Song Yao Hongwei Wang Yao Zhou Shuangchao Liu Xiao Li Shen School of Public Health， Zunyi Medical University Chongqing Fuling district center for disease control and prevention Key Laboratory of Maternal & Child Health and Exposure Science of Guizhou Higher Education Institutes Research and Development Department，Allife Medicine Inc.

Foods and animal feeds frequently become contaminated with the nephrotoxic ochratoxin A (OTA). Our prior research has indicated that ursolic acid (UA)， which is widely present in fruits and medicinal plants， has the potential to alleviate nephrotoxicity triggered by OTA. Additionally， excessive induction of endoplasmic reticulum (ER)-phagy exacerbates OTA-induced apoptosis. Therefore， further investigation is essential to comprehend whether UA can mitigate OTA-induced apoptosis by influencing ER-phagy. This objective is accomplished through a series of experiments involving assessments of cell viability， apoptosis， fluorescence microscopy， and western blot analysis. The outcomes of these experiments reveal that pre-treatment with 4 μmol/L UA for 2 h can markedly reverse the elevated apoptotic rate， the co-localization of ER and lysosomes， and the protein expressions of GRP78， p-eIF2α， Chop， Bax， and Bak， as well as the reduced cell viability and the protein expressions of Lonp1， Trap1， p62， Tex264， FAM134B， Bcl-2， and Bcl-xl， all caused by exposure to 1 μmol/L OTA for 24 h in human proximal tubule epithelial-originated kidney-2 (HK-2) cells (P < 0.05). Interestingly， the increased expression of LC3B-II induced by OTA is further amplified by UA pre-treatment (P < 0.05). In conclusion， OTA triggers a harmful feedback loop between ER stress (ERS) and excessive ER-phagy， thereby further promoting ERS- and mitochondrial-mediated apoptosis in vitro. However， this effect is significantly mitigated by UA through the inhibition of autophagosome-lysosome fusion， consequently blocking the excessive ER-phagic flux.

Surveillance recommendations for gastric cancer(GC) in current guidelines focused on advanced precancerous lesions and were based on precise diagnosis of severity/extent of baseline lesions. We aimed to develop a less endoscopy-related equipment-dependent risk-stratification tool, and assessed whether mild-precursor-lesion patients can be safely exempt from surveillance. In the multicenter communitybased cohort, 75,051 participants receiving baseline endoscopy were enrolled during 2015–2017 and followed-up until 2021. Cumulative incidence rates(CIRs) of GC for precancerous-conditions were calculated by Kaplan-Meier method and compared by Log-rank tests. Mixedeffects Cox regression models were used to detect potential factors for progression towards GC. A risk score was calculated as counts of selected factors. An independent cohort, including 26,586 participants was used for external validation. During a median follow-up of6.25 years, CIRs of GC were 0.302%, 0.436%, and 4.756% for normal group, non-neoplastic(atrophic gastritis/intestinal metaplasia) and neoplastic lesions(low-grade/high-grade dysplasia), respectively(Ptrend<0.001). Four predictors, including male, ≥60 years, smoking, and limited vegetable consumption, were selected for risk-stratification. High-risk patients(≥3 risk factors) with non-neoplastic lesions showed higher GC risks(adjusted HR=7.73, 95%CI: 4.29–13.92), and their four-year CIR reached the one-year CIR of neoplastic lesions. Further categorizing non-neoplastic lesions by histological grade, both patients with moderate-to-severe lesions(aHR=3.07, 95%CI: 1.67–5.64) and high-risk patients with mild lesions(aHR=7.29, 95%CI: 3.58–14.86) showed higher risks. Consistent trends were observed in validation cohort. High-risk mild-precursor-lesion patients should receive surveillance within 3–5 years after baseline screening. Our study provides evidence on supplementing current guideline recommendations.
