Objective To explore the feasibility of local enucleation of pancreatic cystadenoma. Methods From Jan 2001 to Dec 2007, 11 patients with pancreatic cystadenoma underwent operation in Department of General Surgery, first affiliated hospital of China Medical University were enrolled and the clinical features, complications and prognosis were analyzed retrospectively. Results Of the 11 cases, the average age was 47 years old with 2 males and 9 females, the average size of the neoplasm was 4.8cm and 1 located in the pancreatic head, 10 in the body or the tail. Among which 3 cases were serous cystadenoma and 8 were mucinous cystadenoma confirmed by pathological evidence. Three patients developed temporary hyperglycemia and returned to normal after 1~2 weeks; one patient developed incisional infection; two cases developed pancreatic fistula postoperatively. All cases were followed up between 28 and 67 months. No neoplasm re-occurrence or diabetes mellitus occurrence were observed. Conclusions It was safe and feasible to perform enucleation for pancreatic cystadenoma with tumor size less than 6 cm.

BACKGROUND: Previous studies have demonstrated that acidic fibroblast growth factor (aFGF) combined with partially deproteinized bone (PDPB) (aFGF/PDPB) well promotes avascularization in animals with early-stage avascular necrosis of the femoral head (ANFH), but the histological results remain unknown.OBJECTIVE: To observe the histological repairing effects of aFGF/PDPB on early-stage ANFH in rabbits. METHODS: New Zealand rabbits were established models of bilateral ANFH and were randomly divided into a blank group, a simple PDPB group, and an aFGF/PDPB group. PDPB and aFGF/PDPB bone were implanted into the PDPB and aFGF/PDPB group accordingly. The blank group did not receive any implantation. At 2, 4, and 8 weeks after surgery, all animals were sacrificed for histological examination to observe the osteogenesis by hematoxylin-eosin staining.RESULTS AND CONCLUSION: Defects were filled with granulation tissues and fibrous connective tissues, only a little osteoid tissue formed at the borderline in the blank group at the end of the 8th week. In the PDPB group, a little new bone and cavitas medullaris formed. At 8 weeks, lots of graft was absorbed and cavitas medullaris formed with more osteoplasts and myeloid cells in it. The osteogenesis in the aFGF/PDPB group was better than that of PDPB group in each time point. At 4 weeks, the transplanted cavity was filled with osteoid tissues, a lot of osteogenic precursor cells and osteoblasts could be seen. Plenty of micrangium was observed, and osteoid tissues began to rebuild. At 8 weeks, the graft was replaced by bone tissues, and cavitas medullaris were formed with lots of bone marrow cells in it. At the borderline of the bone trabecula, there were lots of osteoplast and little osteoclasts, which may play a role in bone remodeling. There were mature bone cells in bone lacuna. Results indicate that aFGF/PDPB has better repair effect on rabbit model of ANFH than that of simple PDPB.

Almost 3% of newborns are diagnosed as small for gestational age(SGA)worldwide.Born SGA is one of the important causes of perinatal morbidity and mortality,and is also associated with metabolic diseases in adulthood.Low birth weight by itself is insufficient to characterize growth restriction,as it does not include information about the neonate’s body proportionality.Depending on the origin,timing and severity of in-sult,small for gestational age infants are classified into two types:proportionate or symmetric growth restriction (SGR)and disproportionate or asymmetric growth restriction(AGR).There may be differences in physical and neurological development of these two types.This study compares three classification indexes,and to find differ-ences in postnatal growth of these two types.

Objective To investigate the experiences in the diagnosis and treatment of space-occupying lesions of the head of pancreas.Methods The clinical data of 247 patients with space-occupying lesions of the head of pancreas who were admitted to the First Affiliated Hospital of Chinese Medical University from January 2011 to April 2014 were retrospectively analyzed.All the patients received enhanced computed tomnography and (or) magnetic resonance imaging of the pancreas.The levels of alpha-fetal protein (AFP),CA19-9,CA125 and carcinoembryonic antigen (CEA) were detected,and the serum level of IgG4 was detected in patients who were suspected of autoimmune pancreatitis.Intraoperative pathological examination was applied to patients who were diagnosed as with cancer of the head of pancreas.Pancreaticoduodenectomy,extended pancreaticoduodenectomy or bilio-jejunostomy or (and) gastrointestinal anastomosis were applied to patients according to the stage and infiltration of the tumor.Duodenum-preserving pancreatic head resection or pancreaticoduodenectomy could be selected after informed consent.The adjacent tissues and organs should be preserved on the premise of complete tumor resection for patients with benign and low-grade malignancy.Results A total of 194 patients had solid spaceoccupying lesions of the head of pancreas,including 125 with pancreatic head cancer,45 with mnass in the head of pancreas,9 with chronic pancreatitis with mass in the head of pancreas,11 with autoimmune pancreatitis,4 with insulinoma.Fifty-three patients were with cystic space-occupying lesions,including 12 with mucinous cystadenoma,8 with serous cystadenoma,17 with pancreatic cyst,12 with solid-pseudopapillary tumor of pancreas and 4 with intraductal papillary mucinous neoplasm.The positive rates of AFP,CA19-9,CA125 and CEA of the 71 patients who were confirmed as with pancreatic cancer by pathological examination were 7.0％ (5/71),94.4％ (67/71),42.3％ (30/71) and 0,respectively.The positive rates of AFP,CA19-9,CA125 and CEA of the 12 patients with chronic pancreatitis with mass in the head of pancreas were 1/12,4/12,1/12 and 0,respectively.Seventynine patients with pancreatic head cancer,mass in the head of pancreas and chronic pancreatitis with mass in the head of pancreas received intraoperative pathological examination.A total of 119 patients received operation,including 71 with pancreatic head cancer,7 with chronic pancreatitis with mass in the head of pancreas,4 with insulinoma,1 with pancreatic tuberculosis,8 with mucinous cystadenoma,4 with serous cystadenoma,6 with pancreatic pseudocyst,1 with huge lymphangioma,1 with lymphoepithelial cyst,12 with solid-pseudopapillary tumor of pancreas and 4 with intraductal papillary mucinous neoplasm.Of the 247 patients with space-occupying lesions of the head of pancreas,61 received pancreaticoduodenectomy,4 received duodenum-preserving pancreatic head resection,4 received pancreatic head and neck resection,2 received partial resection of the uncinate process of the pancreas,9 received enucleation of the tumor,38 received bilio-jejunostomy or (and) gastrointestinal anastomosis,22 received endoscopic retrograde cholangio-pancreatography + stent installation,18 received percutaneous transhepatic cholangial drainage + stent installation,1 received exploratory lapartomy and the other 88 patients were untreated.Conclusions The diagnosis and differential diagnosis of the space-occupying lesions of the head of pancreas depend on the clinical presentation,medical history,laboratory examination,sonography,computed tomography or magnetic resonance imaging.Individualized treatment plan based on the feature of the tumor and kinds of the lesions combined with intraoperative pathological examination is helpful for selecting the surgical procedures.
