Traditional Chinese medicine (TCM), refined over millennia, embodies distinctive therapeutic principles rooted in the concept of harmony with nature. The oral efficacy of TCM is critically dependent upon the precise absorption and efficient intestinal transport of its complex constituents. However, the underlying mechanisms remain poorly understood, posing a significant challenge to the modernization and global advancement of TCM research. Intestinal organoid technology, which enables three-dimensional in vitro culture of intestinal tissues, accurately recapitulates the cellular heterogeneity, structural organization, and key physiological functions of the native intestine. Recently, the integration of organoids with microfluidic platforms to form “Intestinal Organoid-on-a-Chip” systems has further advanced this field by dynamically recapitulating intestinal peristalsis, absorption, and metabolic activities. These systems provide a more physiologically relevant platform for investigating the transmembrane transport and spatiotemporal dynamics of TCM constituents. This review summarizes the principles, construction strategies, and functional characteristics of intestinal organoid technology, highlights its emerging applications in elucidating the absorption and transport mechanisms of TCM, and discusses current challenges, including standardization, experimental complexity, and clinical translation. Furthermore, it envisions future directions involving multiomics, artificial intelligence, and other cutting-edge approaches, aiming to provide novel strategies to accelerate the modernization and internationalization of TCM research.

Objective To investigate the thyroid diseases in soldiers(aged 30 years and above)stationed on a certain island,and to clarify the value of ultrasonic diagnosis.Methods Thyroid ultrasonography was performed in 270 soldiers(aged≥30 years)stationed on an island by the high-frequency probe of the Mindray Z6 portable B-mode ultrasound diagnostic instrument.According to the C-TIRADS classification,the proportion of soldiers with thyroid nodules was calculated.Results Thyroid nodules were found in 50 soldiers(18.52%),including 29 cases(10.74%,cystic nodules)of C-TIRADS type 2,15 cases(5.56%,solid or cystic nodules)of C-TIRADS type 3,5 cases(1.85%,solid or cystic nodules)of C-TIRADS type 4a,and 1 case(0.37%,solid nodule)of C-TIRADS type 4b.Conclusion Thyroid ultrasound helps to analyze the causes of thyroid diseases,make grading assessment,and provide suggestions for soldiers stationed on islands.Not only does it clarify the necessity of thyroid ultrasonography in the physical examination,but also provides suggestions to improve the medical environment on islands.
