Background:Recurrent acute pancreatitis(RAP)is a special type of acute pancreatitis(AP). Finding the cause is the key to avoid the recurrence of RAP. Aims:To investigate the risk factors of RAP. Methods:The clinical data of 43 patients with RAP and 130 patients with only one time AP(control group)were retrospectively analyzed. Risk factors of recurrence of RAP were analyzed. Results:Univariate analysis showed that no significant differences in etiology,severity, serum levels of cholesterol,calcium,white blood cell count,amylase,ALT,AST,total bilirubin,direct bilirubin and C-reactive protein were found between RAP group and control group(P > 0. 05). Serum triglyceride level,blood glucose level and CT score in RAP group were significantly higher than those in control group(t = 3. 260,P < 0. 05;t = 2. 720, P < 0. 05;t = 2. 162,P < 0. 05). Logistic regression analysis demonstrated that serum triglyceride level,blood glucose level and CT score were risk factors of RAP(oR = 1. 86,95% CI:1. 05-3. 68,P = 0. 03;oR = 1. 23,95% CI:1. 01-1. 50,P = 0. 04;oR = 2. 46,95% CI:1. 00-6. 03,P = 0. 04). Conclusions:The recurrence of RAP is related with serum triglyceride level,blood glucose level and CT score.

Objective:To preliminarily understand the living habits, medication taking and treatment status including the therapeutic regimen, compliance and short-term efficacy of patients with chronic atrophic gastritis and erosion in Beijing area.Methods:From April to September in 2019 at Peking Union Medical College Hospital, Peking University Third Hospital and Peking University Shougang Hospital, the outpatients with chronic atrophic gastritis and erosion diagnosed with endoscopy within two weeks before visiting were prospectively included in this non-interventional observation study. Chi square test was used for statistical analysis.Results:A total of 277 patients with chronic atrophic gastritis and erosion had complete follow-up data, of which male patients accounted for 49.8% (138/277). The common initial symptoms of patients with chronic atrophic gastritis and erosion included acid reflux, abdominal distension, epigastric pain and postprandial distension, which accounted for 60.3% (167/277), 59.6% (165/277) , 58.8% (163/277) and 52.3% (145/277), respectively. For treatment, 36.8% (102/277) of the patients only received lifestyle instruction without medication. Among the patients with medication treatment, the short-term efficacy of gastric mucosal protectants+ proton pump inhibitor+ gastro-kinetic agent for abnominal distension, postprandial distention, acid reflux and nausea was highest as compared with other therapeutic regimen, and the differences were statistically significant ( χ2=25.18, 19.49, 13.75, 8.84, all P<0.05). Conclusions:Chronic gastritis with erosion may be caused by a combination of multiple factors, and the symptoms of which lack specific. If necessary, gastroscopy may help the diagnosis. Individualized treatment strategies based on the symptoms of patients is needed for treatment.
