Objective To retrospectively analyze diagnosis and treatment of chronic pancreatitis. Methods One thousand and seven hundreds patients with confirmed chronic pancreatitis in 21 hospitals were retrospectively studied,including their associated etiological factors,diagnostic and therapeutic methods.Results Among these patients,601 were alcoholic,576 were biliary diseases origin,which ac- counted for 35.4% and 33.9%,respectively.The most common symptom of chronic pancreatitis was abdominal pain.Some of patients accompanied by steatorrhoea and decreased body weight.Part of pa tients(239 cases)were diagnosed by histopathologic examination.Others were diagnosed by imaging techniques.Alleviation of symptoms was achieved with conservative management.Conclusions Alcohol consumption was the most common predisposing factor for chronic pancreatitis.Imaging techniques play the most important role in diagnosis of the disease,and non-operation managements were the main meth- ods for treatment of chronic pancreatitis.

This study was aimed to establish an HPLC method for simultaneous determination of the content of echinacoside, acteoside and isoacteoside in Total Cistanchis glycosides Capsules. Waters C18 column (4.6 mm ×150 mm, 5 μm) was used with the mobile phase of methanol-0.1% formic acid at a flow rate of 1.0 mL·min-1. The detection wavelength was set at 330 nm. The column temperature was maintained at 30℃ . The results showed that the linear ranges of echinacoside, acteoside and isoacteoside were in the range of 27.792-277.92 μg·mL-1 (r = 0.9996,n = 6), 2.4184-24.184 μg·mL-1 (r = 0.9996, n = 6), 5.106-51.06 μg·mL-1 (r = 0.9998, n = 6). The average recoveries of three components were in accordance with the determination requirement. It was concluded that the method was simple and accurate, which can be used in the content determination of echinacoside, acteoside and isoacteoside in Total Cistanchis glycosides Capsules.
