Purpose To detect the expression of autophagic genes Beclin 1 and MAP1LC3 in cutaneous malignant melanoma and to ex-plore the relationship between autophagia and malignant melanoma. Methods 85 cases of speicmens including normal skin tissue, in-tradermal nevi, radial growth phase melanomas, vertical growth phase melanomas, and metastatic melanoma were collected, and the protein expression of Beclin 1 and MAP1LC3 were evaluated by immunohistochemistry of SP methods. Results The Beclin 1 and MAP1LC3 expression were pretended to be 100% in normal skin tissue, and they were declined to 85% and 95% in intradermal nevi, 58% and 50% in radial growth phase melanomas, 49. 5% and 44. 4% in vertical growth phase melanomas, both of 17% in melanoma metastases (P<0. 05). Conclusion Beclin 1 and MAP1LC3 autophagic gene expression were significantly decreased with tumor pro-gression, as well as was correlated with conventional histopathologic prognostic factors.

Objective To analysis the clinical features of dorsal pancreas agenesis ( DPA) and the associated diabetes, pancreatitis and other congenital organ malformations.Methods Chinese databases of Sinomed, CQVIP and CNKI using the term of short pancreas, pancreas agenesis, bulbar pancreas and dorsal pancreas, and English databases of PubMed using the term of dorsal pancreas agenesis, short pancreas and pancreas hypoplasia were searched.The clinical manifestation, pancreatic head characteristics and associations with diabetes, pancreatitis and other congenital organ malformations were analyzed.Results Six related publications from Chinese databases were searched and 21 patients were included with 2 cases excluded.Sixty-one publications from English database were searched and 71 patients were included.Thus, a total of 91 patients with DPA were analyzed.Abdominal pain was the most common manifestation, which was reported by 61.5% of the patients. 15.3% patients were identified during regular physical examination. Other manifestations including jaundice, fatigue, abdominal discomfort and diabetes were rare.After removing cases with insufficient information, 39 patients (61.9%) carried abnormal pancreatic head.Prevalence of diabetes or impaired glucose tolerance was 56.7% and the percentage of insulin-dependent diabetes in patients with abnormal glycaemia was 47.3%(n=18).20 patients (26.7%) were associated with pancreatitis, including 15 patients (75.0%) with acute pancreatitis, 1 patient (5.0%) with recurrent pancreatitis, and 4 patients (20.0%) with chronic pancreatitis. Thirty-three patients ( 36.2%) suffered other congenital organ malformations, including 21 patients (63.6%) with splenic malformation, 8 patients (24.2%) with heart malformation, and 17 patients (51.5%) with multi-organs malformations like gastrointestinal malformation, azygos vein and inferior cava vena fusion, duodenal and biliary atresia and renal absence.Conclusions The main diagnostic criteria of DPA was the absence of dorsal pancreatic duct.Diabetes was the most common complication followed by pancreatitis.
