Objective To explore an objective and standard approach for accurately evaluating peristomal skin lesions and providing comprehensive and professional nursing guidance.Methods Images of peristomal skin were taken by a cell phone camera and then evaluated by medical image processing and analyzing software combined with the condition option.The computer automatically calculates and provides professional nursing advice for patients developing peristomal skin lesions based on ostomy skin assesssment score system and ostomy skin nursing guideline for peristoma skin care.Advice from two ostomy nursing professionals were compared with that from the medical image analyzing software in two different cell phones.Results Results were analyzed by Kendall coordination coefficient W test to analyze the level of coordination among the experts and medical image analyzing system.There was agreement among study groups (W=0.902,P＜0.05) with respect to DET score.Conclusions Application of medical image analyzing software for standard nursing and treatment of peristomal skin lesions provides standardized assessment and professional advice,reduces artificial distinctions and absence of nursing advices,and effectively improves nursing of peristomal skin.

Objective To study the clinicopathological and immunohistochemical features, histogenesis and biological behavior of solid pseudopapillary tumor of the pancreas ( SPT ). Methods Routine HE and immunohistochemical ( SP) methods were used in 20 cases of SPT. Results There were 18 females and 2 males, age ranging from 13 to 48 years with mean age of 25. 3 years. Abdominal pain and palpable mass were among the main complains. Seventeen cases were followed-up from 9 to 120 monthes. Fourteen cases were alive. Tumors were encapsulated, mixed with solid and cystic tissues. Histological features were psudopapillary structure with a fibrovascular core. Immunohistogically, the tumors were positive for a-1-AT ( 17 cases) , vimentin ( 14 cases) , synaptophysin ( 10 cases) , CgA (5 cases) ,CK and insulin (2 cases) ,glucagon and S-100 (1 case) ,PR (14 cases) , ER (1 case) ,pS2 (6 cases) , but all were negative for CEA and gastrin. Conclusion SPT is of low-graded malignancy and a distinct clinicopathologic entity in young female patients with both exocrine as well as endocrine differentiation. The tumor is closely related with sex hormone receptors.
