Chinese Journal of Pathophysiology 2000;0(12):-
AIM: This study was designed to investigate the secretion of VEGF and its receptor (flt-1 or flk-1/KDR) protein by cultured bovine thoracic aortic endothelial cells treated with various insulin concentrations. METHODS: Endothelial cells was isolated from bovine thoracic aorta, and cultured in serum-free medium, then incubated with different insulin concentrations (30 mU/L, 300 mU/L, 3 000 mU/L). The level of VEGF and its receptor (flt-1 or flk-1/KDR) protein were detected by immunohistochemical staining. RESULTS: As compared with no insulin group, the expression of VEGF protein in low insulin concentration (30 mU/L and 300 mU/L) groups were significantly increased (P0.05) was observed. CONCLUSION: Low concentration insulin up-regulates the VEGF protein expression, while high concentration insulin down-regulates the VEGF protein expression in bovine thoracic aortic endothelial cells, but insulin had no directly effect on the VEGF receptor (flt-1 or flk-1/KDR) protein expression in bovine thoracic aortic endothelial cells.

Objective To investigate the protective effect of pentoxifylline (PTX) on bile duct in grafts against ischemia-reperfusion (IR) injury and its potential mechanisms in the animal model of OLTx in miniature swines. Methods After PTX was added to the preservation solution and administrated through hepatic artery, changes of blood flow, activity of ATPase, apoptosis of epithelial cells, and pathomorphology of the bile duct were investigated in the animal model of OLTx in miniature swines. The animals were divided into IR, IR+NS, and IR + PTX groups. Results The results showed that the incidence of biliary necrosis was significantly lower in IR+PTX group than that in IR and IR +NS groups. When compared with those in IR and IR +NS groups, GGT and ALP levels, numbers of apoptosis cells, and scores of pathomorphology were significantly decreased in IR+PTX group, while blood flow, activity of Na +-K +ATPase, Ca 2+ -ATPase of bile duct in grafts were significantly elevated. Conclusion These results suggest that PTX has multiple antagonistic effects against IR injuries of the bile duct. The effects of PTX on bile duct of grafts against IR injuries are possibly correlated with the improvement of the microcirculation, preservation of the ATPase activity of the bile duct, and suppression of the apoptosis of the bile duct cells.

As a method of choice in the treatment of ampulary carcinoma,pancreaticoduodenectomy often demands open procedure.With the development of minimally invasive techniques,laparoscopic pancreaticoduodenectomy was realized in recent years.Because laparoscopic pancreaticoduodenectomy is high technique-demanding,its popularization is restricted.With flexible robotic arnls and three-dimensional imaging,Da Vinci surgical system has overcome the shortcomings of traditional laparoscope to some extent.In March 2010.a 60-year-old female patient with ampulary carcinoma underwent Da Vinci surgical system-assisted pancreaticoduodenectomy at the Southwest Hospital.The mean operation time and blood loss were 490 minutes and 450 ml respectively,and no blood transfusion was required.Out-of-bed activity began shortly after the operation.The gastric tube was removed and fluid diet was given on postoperative day 3.The patient was discharged on postoperative day 10 without incidence of complications.The Success of this case preliminarily demonstrats that Da Vinci snrgical system-assisted pancreaticoduodenectomy is safe and feasible.
