This article delved into the comprehensive study by Jiang et al,which meticulously examined the bidirectional relationships among gallstone disease,nonalcoholic fatty liver disease,and kidney stone disease through a multicenter study,systematic review,and meta-analysis.The study provides significant evidence supporting these associations,offering valuable insights into the etiology and potential prevention strategies for these interconnected conditions.The clinical significance of these bidirectional relationships is profound,as they underscore the importance of recognizing these conditions not only as isolated diseases but as part of a complex network that can influence each other.These results highlight the critical need for thorough screening and personalized prevention strategies for individuals with these interconnected conditions.Explicit implications for prevention strategies and early screening practices are crucial,as they can lead to early detection and intervention,significantly altering disease progression and outcomes.Furthermore,identifying potential therapeutic targets within these shared pathways may enhance treatment efficacy and patient outcomes,making this research highly relevant to clinical practice.By comprehending the common pathophysiological mechanisms and applying specific interventions,healthcare professionals can greatly enhance patient care and lessen the impact of these widespread diseases on global health. 展开更多

OBJECTIVE: To review the current state of research in non-alcoholic fatty liver disease (NAFLD). DATA RESOURCES: Searching Medline (1994-2002) and Chinese Medical Journals Index (1998- 2002) for articles on NAFLD. RESULTS: NAFLD is a new and challenging field with increasing recognition although its pathogenesis is poorly understood. 'Two hits' hypothesis is still the leading theory guiding current research. CONCLUSIONS: Genetic study is a promising way that might lead to breakthrough in NAFLD research. NAFLD study in China is at an initial stage and there is a long way to go. 展开更多
