Brief summary: The purpose of this study is to evaluate the efficacy of the study drug (Ilaprazole Sodium for Injection) for potential effect on preventing stress ulcer bleeding in vulnerable population by comparing the radio of upper gastrointestinal bleeding when they are administered Ilaprazole Sodium for Injection and Esomeprazole Sodium for Injection respectively.

* hemoglobin \< 60g/L (6.0g/dl);
* significant factor indicating bleed occurs during swallowing (such as oral and maxillofacial injuries, hemoptysis, etc.);
* renal failure;
* cardiopulmonary resuscitation conducted during hospitalization period;
* serious liver disease, defined as Child-Pugh C-grade;
* contraindicated for gastric intubation (such as esophageal stenosis);

* participated in other clinical studies within 30 days prior to random assignment;
* use any PPI or treated by H2RA within 12 hours prior to random assignment;
* co-administering or unavoidable using drugs that may interact with Ilaprazole Sodium or Esomeprazole Sodium: e.g., Warfarin (including other vitamin K antagonists), Cisapride, Phenytoin, Atazanavir, Nefenavir, Ritonavir, Saquinavir, Digoxin, Tacrolimus, Methotrexate.
