Objective To introduce transforming growth factor ?(TGF ?) and the relationship between TGF ? and graft rejection. Methods Relevent articles in recent years were reviewed.Results The immunodepressive function of TGF ? could resist transplant organ rejection injury in early postoperative period ; meanwhile TGF ? also caused fibroblast migration and promoted matrix deposition by increasing collagen production and decreasing collagen breakdown via inhibition of collagenases,which resulted in transplant organ fibrosis and arteriosclerosis, gene polymorphisms of the TGF ? were associated with it. Moreover,ischemia reperfusion injury and immunodepressive drug also affected production of TGF ?.Conclusion TGF ? as a pleiotropic and multifunctional cytokine contributes to the development of acute and chronic rejection.

Objective To investigate the effects and mechanism of Panax Notoginseng saponins (PNGS) on rat liver during cold preservation. Methods Using isolated perfusion of rat liver model (IPRL), Fura 2 method was used to measur the concentration of calcium ion in hepatic cells which had been preserved in DMEM solution with different concentration of PNGS added and cold preserved for 2 hours. Liver function, metabolic products of oxygen free radicals, energy substance and aucount of biliary flow as well as morphological study were measured from liver tissue which had been cold preserved in lactate riuges’s solution containing different dosages of PNGS for 24 hours and 30 minutes reperfusion.Results The contents of intracellur calcium of the rat hepatocytes,MDA, AST, ALT, LDH were lower than those in the control group,but SOD, ATP, TAN, EC and bile production were higher than those in the control group( P 0.05). Conclusion PNGS relieve the injury of the rat liver during cold preservation. The mechanism might through inhibition calcium overload, improve the energy metabolism, play a role against free radical injury realize.

Objective To investigate the effect of mild hypothermia on cerebral oxygen metabolism in a rat model of chronic cerebral hypoperfusion and reperfusion. Methods Twelve healthy SD rats weighing 170-210 g were randomly divided into normal body temperature group (group NT, n = 6) and mild hypothermia group (group MH, n = 6). Arterio-venous fistula was established by end-to-end anastomosis between the right common carotid artery and right external jugular vein according to Yassari. Mild hypothermia was induced in group MH before reperfusion and maintained for 3 h. The rectal temperature was reduced to 32 ℃ while in group NT rectal temperature was maintained at about 37 ℃ . Cerebral blood perfusion (CBP) was assessed by using a lasser Doppler perfusion image system before reperfusion (T_1), immediately after reperfusion (T_2) and 24 h after reperfusion (T_3). Venous and arterial blood samples were collected from superior sagittal sinus and femoral artery respectively for blood gas analysis at T_(1-3) . Cerebral arterial venous O_2 saturation difference (Sa-vO_2), cerebral O_2 extraction rate (CERO_2) and cerebral arterial-venous lactic acid concentration difference ( Da-vL) were calculated. Results In NT group left CBP was significantly decreased at T_2 as compared with the baseline value at T_1 , while at T_3 bilateral CBP was decreased. In MH group bilateral CBP was significantly decreased at T_2 but returned to baseline level at T_3. CERO_2 was significantly decreased at T_2 as compared with the baseline value at T_1 in MH group. Da-vL was significantly increased at T_3 in NT group. Compared with group NT, bilateral CBP was significantly decreased, CERO_ and Da-vL were significantly decreased at T_2 ,while no significant change was found in Sa-vO_2 in group MH. Conclusion Mild hypothermia is beneficial for the balance of cerebral oxygen metabolism in the rats with chronic cerebral hypoperfusion and reperfusion.

Objective To explore the mechanism of adenosine triphosphatase (ATPase) of calcium overload in vascular smooth muscle cell (VSMC) in hemorrhagic shock rats. Methods Twenty-four male Wistar rats were randomly divide into four groups: control (Group C), shock start (Group S0), 2 hours post-shock (Group S2) and 4 hours post-shock (Group S4). The rat models with hemorrhage shock were produced by means of modified Wigger's method through bloodletting from femoral artery and keeping blood pressure at 40 mm Hg for 2 hours. The changes of cytosolic free Ca 2+ concentration (i) and the activities of Ca 2+ - ATPase and Na +-K +- ATPase in VSMC membrane and mitochondrial membrane were monitored in rats after shock. Results Mean channel fluorescence values of VSMC i in the Groups C, SO, S2 and S4 were 2.03?0.15, 2.37? 0.32 , 2.55?0.46 and 2.80?0.43 respectively and increased in a time-dependent fashion. Mean channel fluorescence values of VSMC i in the Groups S0, S2 and S4 was significantly higher than that in the Group C ( P
