Objective To understand the value of pre-coating in artificial vessel endothelialization. Methods Literature concerning precoating in artificial vessel endothelialization was extensively reviewed. Results Pre-coating included chemical coatings(collagen, fibronectin, laminin, poly-l-lysin, gelatin andextracellular matrix), pre-clotting(plasma, blood, serum and fibrin glue), chemical bonding (heparin, RGD and lectins) and surface modification. Most of them could enhance the adhesion of the endothelial cells. Conclusion Pre-coating couldimprove endothelialization, but further research is needed to search for the appropriate concentration and incubation time.
ObjectiveTo investigate clinical features and treatment of pancreatic metastasis from cardiac carcinoma.MethodsThe clinicopathological data of a patient with pancreatic metastasis from cardiac carcinoma in the General Hospital of Western Theater Command were retrospectively analyzed. The results of multi-disciplinary treatment (MDT) of this case were summarized.ResultsThe imaging findings of abdomen CT of this patient were that the solid occupying position of the head of pancreas was considered as a new organism. After discussing by the MDT and exclusing operative contraindications, the radical resection of cardiac cancer with pancreaticoduodenectomy and enlarged intraperitoneal lymph node dissection was performed under the general anesthesia. The operation was smooth and the bleeding was about 600 mL. The patient recovered well after the operation and had no serious complications. The patient was discharged on day 10 after the operation. The results of postoperative pathological diagnosis were the cardiac carcinoma with pancreatic head implantation metastasis (stage Ⅱ A, T3M0N0); obstructive jaundice, liver damage, extrahepatic and extrahepatic biliary dilatation. The patient received the intravenous infusion of the oxaliplatin pluse tigualone for 4 courses. The patient was generally in a good condition and had survived 5 months free tumor. The CA19-9 level was 45.6 U/mL (it was 449.60 U/mL before the operation).ConclusionsPancreatic metastasis from cardiac carcinoma is rare and need to be distinguished from primary pancreatic cancer. Survival time is short and prognosis is poor. Clinical symptoms are improved and survival time is prolonged after operation with postoperative chemotherapy.
