Objective To investigate the clinical manifestations of chronic pancreatitis(CP)and choice of the surgical therapy. Methods The clinicopathological and follpw-up data in 91 cases surgically treated in our hospital from January 1980 to January 2006 were retrospectively analyzed.Resuits The causes for CP were biliogenic one in 34 patients(37.4%),alcohol in 14(15.3%),iniury in 8(8.8%),acute pancreatitis in 14(15.3%)and idiopathic one in 20(22%).RelaPsing upper abdominal pain was the major symptom of CP.There were only two patients that were up with endoscopic sphincterotomy(EST)and the others were operated on.The operative morbiditv was 6.6%(n=6),and mortality 1.1%(n=1).Mean hospital stay was 17.7d.For the 9l patients with preoperative pain,the pain was relieved in 88.Conclusion The best operative procedure should be chosen for treatment of CP according to causes,clinical findings,imaging records and pathological examination.

Objective:To establish a method for the determination of chloride and sulfate in lithium carbonate crude drug by sup-pressed ion chromatography. Methods:The analysis column and the guard column was Thermo IonPac AS11(250 mm × 4 mm) and IonPac AG 11(50 mm ×4 mm), respectively. Potassium hydroxide solution(10 mmol·L-1) generated by an eluent generator(EG) was used as the eluent at a flow rate of 1. 0 ml·min-1 . And the temperature of column and conductivity cell was 30℃ and 35℃, re-spectively. The suppressor electric current was 36 mA, and the injection volume was 10 μl. Results:The linear range of chloride ion and sulfate ion was 1. 0-20μg·ml-1 with r of 0. 995 1 and 0. 997 3,respectively, and the recovery was 106. 6%(RSD=2. 6%,n=6) and 100. 3%(RSD=1. 9%,n=6), respectively. Conclusion:The method is accurate and reliable, and can be used in the determina-tion of chloride and sulfate in lithium carbonate crude drug.
