019; IOD: 513.99 ± 79.80 vs 709.63 ± 43.25, p = 0.000). The increased TRPV1 protein expression was tightly correlated with the decreased CB1 protein expression in DRG (r = -0.606, p = 0.037), but TRPV1 was not yet correlated with CB2 protein expression (r = -0.351, p = 0.263). Conclusion: The increased TRPV1 protein expression was strongly correlated with decreased ABT-737 purchase CB1 protein expression of RE rats, which indicated that the acid plays a critical

role in regulation of the receptor molecules. Key Word(s): 1. reflux diease; 2. TRPV1; 3. CB1; 4.

Methods: A randomized and open study in a multi-center was adopted. Clinical observation questionnaire surver was performed on 130 patients to

investigate relevant symptoms of gastroesophageal reflux disease (GERD). They were divided randomly into observed group (domperidone and rabeprazole) and control group (rabeprazole). In a follow-up of 4 weeks, scores were compared between the two groups after the treatment of 2 week and 4 week. Results: Compared with the baseline, the scores of both two groups had declined after CX-5461 nmr 2 week and remarkably declined after 4 week with a significant difference. The observed group showed remarkably improvent of heartburn after 2 weeks and regurgitation after 4 weeks with a significant difference. The observed group showed a higter effective rate on the symptoms of heartburn and regurgitation than the control group after 2 week. Conclusion: The proton pump inhibitors (PPI) with mosapride can rapidly relieve the symptoms of gastroesophageal reflux disease (GERD). Key Word(s): 1. esophagealreflux; 2. mosapride; 3.

朱 Additional Authors: 傅 春彬, 刘 Corresponding Author: 朱 Affiliations: Objective: To explore the research progress of primary gastric mucosa-associated lymphoid tissue lymphoma. Methods: To Phospholipase D1 summarize the etiology, pathogenesis, diagnostic methods and basis, treatment and regimen of gastric MALT lymphoma. Results: Helicobacter pylori (HP) infection is the important cause of gastric MALT lymphoma, the chromosomal abnormality and the expression of NF-κB molecular pathway is also the important pathogenic factor in gastric MALT lymphoma. The chromosomal abnormalities include t (11; 18) (q21; q21), t (1; 14) (p22; q32), t (14; 18) (q32; q21) and so on. Endoscopy and immunohistochemical examination are helpful in diagnosis of this disease. Treatments include the HP eradication therapy, radiotherapy, surgery, chemotherapy and molecular targeted therapy. Conclusion: HP infection and chromosomal abnormalities are the major causes of gastric MALT lymphoma.
