Pancreatic surgery has achieved substantial improvement in recent years,which was indicated by the continuous decrease of its mortality and morbidity.However,the over-all 5-year survival rate of pancreatic cancer patients has not been significantly improved,and puzzles together with controversies remain in the field of surgical treatment for this devastating disease.Clinical outcomes of pancreatic cancer patients remain poor,which we thought would largely explained by the extremely malignant biological behavior of pancreatic cancer.In this review,we also focused on the frequently discussed themes in the field of surgical treatment for pancreatic cancer.These themes include differential diagnosis for pancreatic head mass,preoperative biliary drainage for jaundice patients,value of R0/R1 resection for pancreatic cancer,pancreatic fistula and delayed gastric emptying after pancreaticoduodenectomy.

How to make a surgeon? It's not an easy question to answer for some of the graduates with doctor degree (Ph.D.).Because the lack of systemic training and stringent qualification exams in the filed of surgery in our country,Ph.D.need to improve their clinical ability and also shift their roles when they are entering the world of surgery.In this article,the author would like to discuss the way to help Ph.D.in accelerating their changing process from a Ph.D.to a capable confident surgeon based on the author's personal experience.Ph.D.are suggested to improve themselves in the following ways:study like a humble student,learn how to improve oneself through observation,practice diligently on basic technique skills,be brave in surgical practicing,read and write as much as you can,and last but not least cultivate your professionalism.

Pancreaticoduodenectomy (PD) is the procedure for treating adenocarcinoma in periampullary region.This involves resection of multiple organs and complex reconstructions.The modern surgery has witnessed the dramatic improvement in outcomes after PD.Mortality has dropped to less than 4％,however,the complication rate remains high,making this procedure still a big challenge for most surgeons. PD is so complicated that even small mistakes could jeopardize the whole procedure and outcomes.With experiences of over 1000 PDs,we discuss the challenges of this procedure and strategies to deal with them.

There was never a time in history that so many disciplines and specialists participate and try to lead the clinical management for acute pancreatitis. Chaos remains at bedside, and episodes of under-intervention and especially over-treatment frequently happened. Physicians are easily confused by questions and controversies in management for acute pancreatitis. We have reviewed the articles in acute pancreatitis and made our recommendations based on the latest evidences.

Objective To study the clinical evaluation of calf blood as a combination of aspirin and aspirin for ischemic stroke and its effect on peripheral blood BCL-2,BAX and Caspase-3,IL-6 and pathogens.Methods 128 patients with ischemic stroke were enrolled in our hospital from September 2014 to October 2016.The patients were divided into observation group and control group by throwing coin method.The control group was treated with oral aspirin tablets and some conventional medical treatment,and the observation group on the basis of this increase in calf blood to the protein injection for treatment,the hemorheology,Barthel index,the national institutes of health stroke scale(NIHSS score)and peripheral blood BCL-2,BAX and Caspase-3 protein content of two groups were recorded before and after treatment.Results After treatment,the total effective rate in the observation group(96.9％)was significantly higher than that in the control group(71.9％),the NIHSS score and hemorheological index of the observation group were significantly lower than those of the control group,Bclhel index was significantly higher than that of the control group,the content of BCL-2 protein in the peripheral blood of the observation group was significantly higher than that of the control group,the levels of BAX and Caspase-3 protein in the peripheral blood of the observation group were significantly lower than those of the control group,the difference was statistically significant(P<0.05).Conclusion The clinical effect of calf blood protein injection combined with aspirin in the treatment of ischemic stroke can not only improve the daily life ability of patients,but also can improve the hemorheology and peripheral blood BCL-2; BAX,Caspase-3 protein content.

Pancreatic neuroendocrine neoplasms (pNENs) can be divided into functional and non-functional.Insulinomas,gastrinomas,glucagonomas and VIPomas are the common types of pNENs.Radical resection is the only way for curing pNENs or for a long-time survival of patients.The basic surgical procedures for pNENs are consist of local resection (tumor enucleation) or anatomical resection [pancreatoduodenectomy (standard or pylorus-preserving pancreatoduodenectomy),distal pancreatectomy (combined with splenectomy or spleen-preserving pancreatectomy) and middle segmental pancreatectomy].Liver is the most common site for metastases.Surgical resection is the method of choice for liver metastases.Radiofrequency ablation,transcatheter arterial chemoembolization and liver transplantation could be the adjunctive therapies.

Radical resection is one of the important factors for improving the prognosis of patients with resectable carcinoma of head of the pancreas,carcinoma of the distal bile duct and periampullary carcinoma.In order to proceed with a R0 resection,there are many types of pancreaticoduodenectomy (PD) for pancreatic,biliary and periampullary carcinoma such as PD with lymphadenectomy.In this report,we described a PD with extended retroperitoneal lymphadenectomy (D2 +) for the adenocarcinoma of the distal bile duct.The case presented underscores the feasibility and safety of PD with D2 + lymphadenectomy.

Objective To investigate the molecular mechanism underlying lymphocyte functionassociated antigen-1 (LFA-1) / intercellular adhesion molecule-1 (ICAM-1) mediated anti-neoplastic effects of cytokine induced killer (CIK) cells. Methods Lymphocytes isolated from peripheral blood of children leukemia were induced with interferon-gamma (IFN-y), anti-CD3 monoclonal antibody (CD3McAb) and interleukin-2 (IL-2) and co-cultured with dendrite cells (DC) to generate DC-CIK cells. When treated with LFA-1 monoclonal antibody, cytotoxicity of DC-CIK cells against leukemia cell lines was measured by the MTT assay, while RT-PCR and Western blotting were used to determine mRNA and protein expressions of GATA-3 and T-bet in DC-CIK cells, respectively. IL-12, IFN-γ and tumor necrosis factor-α (TNF-α) levels released by DC-CIK cells were quantified by ELISA. Results Induced DC-CIK cells were regular, round and transparent with variable cell volume and cellular aggregation. When treated with mouse anti-human LFA-1 monoclonal antibody, the cytotoxicity decreased mostly towards B95 cells under administration of 20 μg/ml LFA-1 monoclonal antibody in comparison with the control group(t =10.138, P ＜0.05). It led to a highest elevation of GATA-3 mRNA and protein levels (t =16.386, P ＜ 0.05; t =22.652, P ＜ 0.05) and a most decrease of T-bet mRNA and protein levels (t =17.728, P ＜0.05; t =17.452, P ＜0.05) under 20 μg/ml LFA-1 monoclonal antibody in B95 cells group in comparison with the control group. The expression levels of IL-12,IFN-γ, and TNF-o in supernatant were the lowest under 20 μg/ml LFA-1 monoclonal antibody in B95 cells group in comparison with the control group (t =21.621, P ＜0.05; t =13.739, P ＜0.05; t =15.278, P ＜0.05).Conclusion GATA-3 and T-bet were implicated in the LFA-1/ICAM-1 mediated anti-neoplastic effects of DC-CIK cells via activation of the Th1 pathway, with high secretion of Th1 cytokines, such as IL-12, IFN-γ and TNF-α.

Objective: To discuss the treatment of pancreatic encephalopathy(PE).Methods: Recombinant human growth hormone (rhGH)(Saizen)were applied in patients of severe acute pancreatitis(SAP) with suspicious early PE that presented with mental disorders. rhGH was also used in combination with somatostatin as the therapeutic method for SAP and its complication.Dosage and administration: Saizen 4U was injected intramuscularly twice a day for 5～7 days.Results: In 7 patients of this group, all of them showed improvement in the aspect of mental dysfunction and the symptoms disappeared after 48～72 hours. In 13 SAP cases underwent combined application of rhGH and somatostatin, no PE was observed.Conclusion: Application of rhGH showed therapeutic effect on the early manifestations of PE. It also suggested that combined use of rhGH and somatostatin could decrease the occurance of PE.
