Objective To introduce the current status of treatment of severe acute pancreatitis (SAP). Methods This summarization paper of SAP was made on literature review. Results During the stage of acute reaction , therapy should be emphasized on non surgical management, such as maintaining the homodynamics ; inhibiting the overexpress of cytokines and pancreatic secretion; administering antibiotics preventively, TPN and improving the function of other damaged organs.The operation timing should be delayed if possible.Thus it could increas the cure rate, decrease complications and the possibility of reopeneration. But in the case of SAP with biliary obstruction, secondary infection with necrosis of pancreas; failure to respond to initial intensive treatment and clinical diagnostic was uncertain, early surgery should be performed. The operation should be easy to be done, ensuring enough drainage, and resolving the obstruction of biliary tract. During the septic stage, besides administerded antibiotics and EN, surgery is primary therapeutic method: necrosectomy and continuous closed lavage were considered as a better treatment of infected necrosis focus, while pancreatic absecess should be drained operatively. During the last stage of residual infection, abdominal abscesses should be drained thoroughly. Conculsions According to the etiology and stage of SAP, comprehesive management guided by "individualized plan"is probably a better strategy of treatment of SAP.

Objective To investigate the effects of endogenous estrogen on blood glucose level,serum insulin level,and plasma total antioxidant capacity in streptozotocin-induced diabetic female mice,and to explore possible protective effects of estrogen on pancreatic islet cells.Methods Female mice were randomly according to body weight divided into four groups:( 1 ) Sham( Sham operation and vehicle administration) ; ( 2 ) Ovx( ovariectomy and vebicle administration ) ; ( 3 ) Sham + STZ ( Sham operation and STZ administration ) ; and ( 4 ) Ovx + STZ ( ovariectomy and STZ administration).The diabetic mice were induced by intraperitoneal injection of streptozotocin (STZ,50 mg/kg ).Blood glucose levels were measured once a week.Results The blood glucose level and malondialdehyde of Ovx group were higher than that in Sham group,while total anti-oxidant capacity ( T-AOC ) was lower than those in Sham group.the blood glucose level and MDA of Ovx+ STZ group were higher than those in Sham +STZ group,while T-AOC and serum insulin level were lower than those in Sham + STZ group.Conclusions Endogenous estrogen may have some protective effects on pancreatic islet function from streptozotocin-induced diabetes mellitus in female mice.

Objective: To evaluate the diagnostic value of saline infusion test (SIT) in patients with primary aldosteronism (PHA). Methods: A total of 116 patients with PHA or essential hypertension (EH) treated in our hospital from 1994-06 to 2013-05 were retrospectively studied. The patients were divided into 2 groups: PHA group,n=72 and EH group, the patients with excluded PHA,n=44. post-SIT plasma levels of aldosterone and post-SIT ratio of aldosterone/renin activity were evaluated by ROC curve in order to analyze the diagnostic capability and the best diagnostic cut-off point. Results: The area under curve (AUC) by ROC for post-SIT aldosterone level was 0.759, the sensitivity and speciifcity were 74.6% and 63.6% respectively; AUC for post-SIT ratio of aldosterone/renin activity was 0.899, the sensitivity and speciifcity were 83.6% and 88.6% with the best diagnostic cut-off point at 111 [ng/dl:ng/(ml?h)]. Conclusion: Post-SIT plasma level of aldosterone and post-SIT ratio of aldosterone/renin activity had the diagnostic value of PHA; post-SIT ratio of aldosterone/renin activity had the higher diagnostic value of PHA.

Objective: To evaluate the clinical value of Captopril test for diagnosing primary aldosteronism (PA) and to calculate the best cut-off point for PA diagnosis. Methods: We retrospectively analyzed 96 PA patients with conifrmed diagnosis by clinical situation, laboratory test and auxiliary examination in our hospital from 1994-06 to 2012-05, and meanwhile, studied 45 highly suspicious PA patients with final exclusion by confirmed diagnosis of primary hypertension (PH). All patients received the in-hospital Captopril test, the area under the curve of receiver operating characteristic (AUCROC) was applied to evaluate plasma aldosterone level and the ratio of aldosterone/renin after Captopril test and to obtain the best cut-off point with the corresponding sensitivity and speciifcity for PA diagnosis. Results: At 1h and 2h after Captopril test, AUCROC for plasma levels of aldosterone were 0.831 and 0.818, the ratios of aldosterone/rennin were 0.909 and 0.922 respectively. At 1h after Captopril test, the cut-off point of aldosterone level was 544.95 pmol/L and the diagnostic sensitivity was 70%, speciifcity was 90.7%; at 2h after Captopril test, the cut-off point of aldosterone level was 466.8 pmol/L and the diagnostic sensitivity was 69.8%, speciifcity was 70.5%. At 1h after Captopril test, the ratio of aldosterone/rennin was 34.6 [ng/dl: μg/(ml·h)] with the sensitivity at 78.3% and speciifcity at 88.4%. At 2h after Captopril test, the maximum AUCROC for the ratio of aldosterone/rennin was obtained, when cut-off point of aldosterone level was 42.2[ng/dl: μg/(ml·h)] , the diagnostic sensitivity was 76.7%, speciifcity was 95.3%. Conclusion: At 1h and 2h after Captopril test, plasma aldosterone level and the ratio of aldosterone/rennin had been valuable for PA diagnosis, the maximum diagnostic value could be obtained at 2h after Captopril test.
