Objective To summarize and discuss the diagnostic and treating experiences of chronic pancreatitis with mass in the head. Methods Eight patients of chronic pancreatitis with mass in the head who were misdiagnosised as carcinoma of head of pancreas were analyzed retrospectively in the past 10 years. Results All the patients exhibited abdominal pain,5 of whom were with jaundice and 3 with anorexia. All the patients were misdiagnosised as carcinoma of head of pancreas before the operation,but the pathology after operation indicated chronic pancreatitis. The pancreaticoduodenectomy was performed in 5 patients,the choledochojejunostomy in 2 patients,while the exploratory laparotomy in 1 patient. After the operations,the abdominal pain was relieved in 7 patients, while 2 patients who accepted pancreatoduodenectomy suffered from pancreatic fistula,1 of whom died in the end. Conclusion It’s hard to differentiate the chronic pancreatitis with mass in the head from the carcinoma of head of pancreas before operation. If the carcinoma of head of pancreas can’t be excluded during the operation,the pancreatoduodenectomy should be performed,while the duodenum-preserving total resection of the head of the pancreas or any intra-drainage operations should be done if chronic inflammation is found in the whole pancreas with a negative result of the biopsy of the pancreas through the needle aspiration.

AIM:To examine and compare the effects of several ARBs that are widely used in clinics , on the ACE-Ang II-AT1 receptor and the ACE2-Ang(1-7)-Mas axis during the development of cardiac remodeling after pressure overload .METHODS: All of the mice used in the study underwent transverse aortic constriction (TAC) or sham operation for 2 or 4 weeks.A solution of either ARBs or sa-line was administered through a stomach tube 3 days before the operation .Meanwhile , to eliminate the influence of Ang II , a recombi-nant adenovirus expressing small interfering RNAs targeting angiotensinogen ( Ad-ATG siRNA) was injected via the tail vein .The sur-gery was then performed and the drug was administered as mentioned above .Cardiac function and remodeling were evaluated by echo-cardiography , hemodynamic measurements and cardiac histology .Western blotting was used to determine the protein expression levels . Meanwhile , we performed similar experiments using ARBs with or without ATG siRNA in cardiomyocytes induced by mechanical stretch.RESULTS:Although all of the six ARBs , none of which repressed the elevation of left ventricular pressure after TAC , attenu-ated the development of cardiac hypertrophy and heart failure in the wild-type mice, the degree of attenuation by Olmesartan , Candesar-tan and Losartan tended to be larger than that of the other three drugs tested .Additionally , the degree of downregulation of the ACE-Ang II-AT1 axis and upregulation of the ACE2-Ang(1-7)-Mas axis was higher in response to Olmesartan, Candesartan and Losartan administration in vivo and in vitro.Additionally, Olmesartan had a larger influence when administered long term .However, the expres-sion of ACE was not influenced by the administration of ARBs in vivo and in vitro.Moreover, in angiotensinogen-knockdown mice, TAC-induced cardiac hypertrophy and heart failure were inhibited by Olmesartan , Candesartan and Losartan but not by Telmisartan , Valsartan and Irbesartan administration .Furthermore , only Olmesartan and Candesartan could downregulate the ACE-Ang II-AT1 axis and upregulate the ACE2-Ang(1-7)-Mas axis in vitro.CONCLUSION: Olmesartan, Candesartan and Losartan could effectively in-hibit pressure overload-induced cardiac remodeling even when with knockdown of Ang II , possibly through upregulation of the expres-sion of the ACE2-Ang(1-7)-Mas axis and downregulation of the expression of the ACE-Ang II-AT1 axis.In contrast, Telmisartan, Valsartan and Irbesartan only played a role in the presence of Ang II , and Losartan had no effect in the presence of Ang II in vitro.
