The patient’s serum AFP was decreased to 23.15 ng/ml on the day 29 after operation. Postoperatively the serum AFP level gradually increased to 1200 ng/ml 5 months after surgery. A recurrent mass in the residual pancreas, and liver metastases were found by CT. Hepatic metastases were treated with hepatic arterial embolization and percutaneous radiofrequency ablation (RF) at another hospital. Sixteen months after surgery, the patient’s condition is stable, and he has fluctuating levels of AFP averaging around 700 ng/ml. Conclusion: This is first case of AFP-producing pure pancreatic neuroendocrine carcinoma. Serum levels of AFP are a useful marker for monitoring

therapeutic response, LY2606368 datasheet recurrence or metastasis in this disease. Key Word(s): 1. AFP; 2. pancreas; 3. Neuroendocrine; 4.

Methods: MiaPaCa2 cells were transfected with Beclinl siRNA expression vector. The Beclinl expression in cells were detected by RT-PCR and Western blot. The cell cycle and apoptosis detection of cell

pancreatic cancer cells interferenced by Beclinl were applicated after using gemcitabine. Results: The MiaPaCa2 cell cycle was shortened in S phase

and G2 phase after the transfection of Beclin1-siRNA DAPT gene, but there was no change happened in cell apoptosis. Conclusion: The expression of Beclinl gene could inhibit the cell cycle distribution of the human pancreatic cancer cell line click here MiaPaCa2 and influence the cell cycle and apoptosis started by the gemcitabine.

Pancreatic cancer; Presenting Author: WU QING Additional Authors: TANGGUO DU Corresponding Author: TANGGUO DU Affiliations: guangxi medical university Objective: Atlanta classification divides patients with acute pancreatitis (AP) into mild and severe disease. In 2012, a revision severity classification has been proposed based on the presence or absence of persistent organ failure (lasts more than 48 hours) and local complications, including acute peripancreatic fluid collection (APFC), acute necrotic collection (ANC), pseudocyst and walled-off necrosis (WON), giving rise to mild, moderately severe, and severe groups. The aim of this study was to validate this new system of severity classification by analyzing markers of severity and outcome. Methods: Medical records and data were reviewed and analyzed of 166 AP patients who were admitted in the first affiliated hospital of Guangxi Medical University between October 2009 and September 2012.
