Objective: To study the effects of halothane and sevoflurane on myocardial function and energy metabolism. Method:The model of Langendorff perfused isolated rat heart was used to investigate the effects of halothane and sevoflurane on HR,LVEDP,LVDP,+dp/dt,-dp/dt and coronary flow(CF)before and after ischemia. and the myocardial ATP content were measured with HPLC before ischemia and 10 min after ischemia and at the end of reperfusion. Result: 1.5 MAC sevoflurane significantly increased CF in normal isolated rat hearts. Both halothane and sevoflurane differently depressed myocardial contratile function,increased normal myocardial energy storage. At 10th min of ischemia the decrease of myocardial ATP content was delayed by halothane and sevoflurane. At the end of reperfusion,the both anesthetics improved the recovery of myocardial function and matebolism,especially sevoflurane. Conclusion: Both anesthetics can protect myocardium from ischemic reperfusion injury through improving post-ischemic myocardial energy recovery.

OBJECTIVE:To explore the protective effect of L-ornithine-L-aspartate on ischemia-reperfusion injury after partial hepatectomy. METHODS:104 patients underwent partial hepatectomy(vessel occlusion in portal fissure)were randomly divided in-to control group(53 cases)and trial group(51 cases). Control group was given routine liver-protective drugs,and trial group was additionally given L-ornithine-L-aspartate 10 g added into 5%Glucose injection 250 ml intravenously before surgery,for 7 consecu-tive days. The fasting peripheral venous blood was collected in 2 groups on first day before surgery and first,forth and sixth day af-ter surgery to detect liver function;the changes of main aminopherase index(ALT and AST)were compared between 2 groups at different portal fissure vessel occlusion time after surgery. RESULTS:There was no statistical significance in the difference of liver resection range,blood loss,first porta hepatis vessel occlusion time and anesthesia time in both groups during operation (P>0.05). Compared to before surgery,liver function indexes raised to different extent in 2 groups after surgery,with statistical signifi-cance(P<0.05). The levels of AST and ALT in trial group were significantly lower than in control group on first,forth and sixth day after surgery,while albumin level was significantly higher than control group,with statistical significance(P<0.05). Total bili-rubin levels of both groups were approximate basically,there was no statistical significance(P>0.05). Among those patients under-went porta hepatis vessel occlusion with Pringle method and with occlude occlusion time ≥15 min,the AST and ALT level of con-trol group was higher than those of trial group after surgery,but albumin level was below trial group,with statistical significance (P<0.05). CONCLUSIONS:L-ornithine-L-aspartate could improve liver function fast and effectively for partial hepatectomy pa-tients,especially for the patients underwent porta hepatic vessel occlusion with Pringle method for a long time(obvious ischemia-re-perfusion injury).

[Objective]To study the mechanism of tubular epithelial hypertrophy induced by high glucose.[Methods]Human tubular epithelium line HK-2 cells were cultured in DMEM/F12 medium containing 1 g/L glucose(normal control group),4.5 g/L glacose(high slucose group),and 1 g/L glucose+3.5 g/L mannitol(iso-osmia control group),respectively.The cells of every group after cultured for 24 h,48 h.and 96 h were collected.The mRNA levels of CTGF and p27~(kip) were detected by real-time PCR.The protein levels of CTGF and p27~(kip) were detected by Western blot.The cellular proliferative activities were observed by MTT.The total cellular protein contents were detected by Bradford method.The cell cycle process was analyzed by flow cytometry.The cells of every group after being cultured for 30 win,1 h,24 h,and 48 h were collected.The levels of phospho-ERK1/2 were detected by Western blot.Every step was repeated for 3 times.[Results]High slucose could significantly up-regulate the mRNA and protein levels of CTGF and p27~(kip),activate ERK1/2 signal conductive pathway in HK-2 cells,make more cells arrest in G1 phase,decrease cellular proliferative activities,increase total cellular protein content reflecting cellular hypertrophy.[Conclusion]CTGF is an important mediator of tubular epithelial hypertrophy induced by high slucose.The mechanism is that CTGF up-regulates the p27~(kip) expression through activating ERK1/2 pathway.Up-regulated p27~(kip) lead proliferative cell to be arrested in G1 phase and cause cellular hypertrophy.
