Filter by:Ciprofol is a new general anesthetic, which combine with γ- Aminobutyric acid-a (GABAA) receptor. Ciprofol has shown equivalent anesthetic efficacy of propofol at 1/4 to 1/5 of the dosage. Ciprofol has the pharmacodynamic characteristics of rapid onset, stable and rapid recovery. Phase III clinical results showed that the incidence of injection pain and respiratory and circulatory depression of ciprofol was lower than that of propofol. Therefore, ciprofol has a good application prospect in the sedation for gastrointestinal endoscopy, especially for overweight and obese patients. We conduct a Multicenter, Randomized, Open-label, Propofol-controlled Study to Evaluate the incidence of hypoxia and severe hypoxia during Gastroenterological Endoscope sedated with CiProfol in Overweight or Obesity patients.

In the current study, we would explore the proper dose of Ciprofol in sedated gastrointestinal endoscopy in obese patients.
The purposes of this study are to collect and store samples including blood, normal and tumor tissue from patients with colorectal cancer or gastric cancer, to collect and store samples including blood and/or normal gastrointestinal tissue (if available) from patients with non-malignant disease (including, but not limited to, inflammatory bowel disease (IBD), gastric ulcer, hemorrhoids or hernia), and to create a database for the collected samples and allow access to relevant clinical information for current and future protocols.
Helicobacter pylori (H.pylori) is a major human pathogenic bacterium in gastric mucosa which is linked to the development of gastritis, peptic ulcer disease, mucosa-associated lymphoid tissue lymphoma and gastric cancer. However the regulatory mechanism of H.pylori-induced immune response is not clear. Long non-coding RNA (lncRNA) has recently emerged as key post-transcriptional regulators of gene expression, differentiation. The investigators had a preliminary results which THRIL (TNFα and hnRNPL related immunoregulatory lincRNA) and PACER(p50-associated COX-2 extragenic RNA) played a potential role in H.pylori induced inflammatory cascade. However, there wasn't a previous study about expression of THRIL, PACER in a human tissue. Therefore, the investigators aimed to evaluate the expression of THRIL, PACER in patients with gastrointestinal disease according to H.pylori infection.
The present study is a feasibility study to assess the safety and efficacy of wireless capsule endoscope and compare the data obtained with those obtained by using a conventional esophagogastroduodenoscopy. The product was developed and manufacture in China.(the NaviCam. AKC-1.China)
Clopidogrel causes significantly less peptic ulcer disease (PUD) and ulcer bleeding than low-dose aspirin in general population. However, clopidogrel is not safe enough for gastrointestinal (GI) mucosa in patients who had past history of aspirin-associated ulcer or ulcer bleeding. Aspirin plus proton pump inhibitor (PPI) is superior to clopidogrel alone in preventing recurrent ulcer bleeding in these high risk patients. This study is to compare the ulcer healing rate and ulcer bleeding at 12 weeks in patients with aspirin-associated PUD when they take PPI (rabeprazole 20 mg/day) to treat their PUD and simultaneously take aspirin or clopidogrel for their cardiovascular (CV) prevention. Two hundred patients will be randomly assigned rabeprazole (20 mg/day) plus aspirin (100 mg/day) or rabeprazole (20 mg/day) plus clopidogrel (75 mg/day) for 12 weeks. The primary end point is treatment success (ulcer healing rate). The secondary end point is incidence of ulcer bleeding within 12 weeks. If rabeprazole plus aspirin in not inferior to rabeprazole plus clopidogrel in the incidence of ulcer healing and ulcer bleeding in the healing phase,PPI plus aspirin rather than PPI plus clopidogrel will be recommended during acute ulcer healing in patients who need antiplatelet therapy for their CV prevention.
Recently, cytokine polymorphisms are considered to play an important role in the pathogenesis of peptic ulcer and gastric cancer. We intended to clarify the association between polymorphisms of pro-inflammatory and anti-inflammatory cytokines, and the susceptibility to gastric cancer, gastric ulcer and duodenal ulcer in Japan, and to detect the individuals who have higher risks for gastrointestinal disease development.
Proton pump inhibitors (PPIs) are mainly metabolized in the liver by CYP2C19, one of the cytochrome P450 isoenzymes, which shows a genetic polymorphism associated with enzyme activities. The most essential role of a PPI in H. pylori eradication therapy is to make antibiotics more stable and bioavailable in the stomach by raising intragastric pH to neutral levels. Most patients who have failed in the eradication of H. pylori infection by triple therapy with a PPI, amoxicillin (AMPC) and clarithromycin (CAM) at standard doses have extensive metabolizer (EM) genotypes of CYP2C19 and/or are infected with CAM-resistant strains of H. pylori. Four-times daily dosing of a PPI could achieve complete gastric acid inhibition. Dual therapy with 4-times daily dosing of a PPI and AMPC could yield sufficient re-eradication rates in patients with EM genotype of CYP2C19. Metronidazole (MNZ)-based re-eradication therapy, such as triple PPI/AMPC/MNZ therapy, also achieved high eradication rates and has been recommended as the second line therapy in Japan. But carcinogenic actions of MNZ have been unclear. The purpose of this study is to compare the re-eradication rates of H. pylori infection by the dual high-dose PPI/AMPC therapy and triple PPI/AMPC/MNZ therapy, and to validate the efficacies of these re-eradication regimens as second line eradication therapies.
The eradication rate of the standard H. pylori eradication therapy (such as the triple therapy with a proton pump inhibitor [PPI], amoxicillin and clarithromycin) depends on bacterial susceptibility to clarithromycin and genotypes of CYP2C19 in patients. The investigators intend to investigate whether the tailored therapy based on the two above-mentioned factors increases the cure rate of the initial eradication therapy.
