AIM: Dieulafoy's lesion (DL) accounts for 1-5.8% of cases of acute upper gastrointestinal bleeding (GIB). Its mortality is high, approaching 20%, despite recent advances in endoscopic therapy. We aimed to report our experience in the treatment of ***: A retrospective case study of all patients with DL between January 1993 and January 2003 was done. Characteristics, treatment methods, success rates and 30-d mortality of the patients were analyzed. RESULTS: Thirty-six patients were noted to have DL in the study period. Thirty-three records were available for assessment in which 35 DL were identified. The median age of the patients was 67 years with male to female ratio of 5.6:1. Significant comorbidities existed in 69% of the patients. Eighty-nine percent of the DL was found at first endoscopy, three DL at laparotomy. Significant coexistent endoscopic findings existed in 23%. Hemostasis was achieved in 88% by using adrenaline injection, or in combination with heater probe application at first endoscopy. Four cases had re-bleeding, all were successfully treated endoscopically. The 30-d mortality rate was 23%.CONCLUSION: Successful endoscopic hemostasis could be achieved in 100% of cases of DL. The overall mortality may still remain high, mainly due to the comorbidities and age of these patients.

Elucidating the complex dynamic cellular organization in the hypothalamus is critical for understanding its role in coordinating fundamental body functions. Over the past decade, single-cell and spatial omics technologies have significantly evolved, overcoming initial technical challenges in capturing and analyzing individual cells. These high-throughput omics technologies now offer a remarkable opportunity to comprehend the complex spatiotemporal patterns of transcriptional diversity and cell-type characteristics across the entire hypothalamus. Current single-cell and single-nucleus RNA sequencing methods comprehensively quantify gene expression by exploring distinct phenotypes across various subregions of the hypothalamus. However, single-cell/single-nucleus RNA sequencing requires isolating the cell/nuclei from the tissue, potentially resulting in the loss of spatial information concerning neuronal networks. Spatial transcriptomics methods, by bypassing the cell dissociation, can elucidate the intricate spatial organization of neural networks through their imaging and sequencing technologies. In this review, we highlight the applicative value of single-cell and spatial transcriptomics in exploring the complex molecular-genetic diversity of hypothalamic cell types, driven by recent high-throughput achievements.

An integrally coupled wave-tide-surge model was developed and then applied to the simulation of the wave-typhoon surge for the typhoon Isewan （typhoon Vera （5915））, which is the strongest typhoon that has struck Japan and caused incalculable damage. An integrally coupled tide-surge-wave model using identical and homogeneous meshes in an unstructured grid system was used to correctly resolve the physics of wave-circulation interaction in both models. All model components were validated independently. The storm surge and wave properties such as the surge height, the significant wave height, wave period and direction were reproduced reasonably under the meteorological forcing, which was reprocessed to be close to the observations. The resulting modeling system can be used extensively for the prediction of the storm surge and waves and the usual barotropic forecast.
