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 investigate the expression of apoptosis-related genes Bcl-2 and Bax after cerebral ischemic reperfusion in hippocampal CA1 and CA3 areas and the effect of curcumin on the expression of Bcl-2 and Bax in gerbils.Methods Gerbils were randomly divided into sham group(SH),ischemia-reperfusion group(IR),curcumin group(CU) and solvent control group(SC).Forebrain ischemia was induced by occlusion of bilateral common carotid arteries.Observations were made in each group 1d,3d,5d and 7d after ischemia.Open field test was used to examine the behavioral change.The apoptotic neurons in hippocampal CA1 region was counted,and the expression of Bcl-2 and Bax in hippocampal CA1 and CA3 areas was detected by SABC immunocytochemical technique.Results The behavioral mark and the number of apoptotic neurons in hippocampal CA1 and CA3 areas were much smaller in CU group than in IR group(P

Objective The mortality rate of the children after surgical repair of congenital heart disease associated with acute renal injure has been reported to be 30％-79％.Peritoneal dialysis is the common treatment method for those patients,but the optimal time to initiate peritoneal dialysis is still controversial.The aim of this study was to investigate the clinic outcome of early peritoneal dialysis to the children following cardiac surgery.Methods We performed a retrospective chart of children following cardiac surgery from January 2008 to December 2009.The total number was 4561,62 of them were performed PD treatment.Data on the PD treatment children were collected from pre-operation to hospital discharge.Early peritoneal dialysis group was defintes as PD initiated at operation room or the interval between the end of operation to starting peritoneal dialysis less than 3hrs.the others were traditional PD group.Results The whole PD treatment rate was 1.36％,15 patients died.The mortality were 10.71％ (3/28) in early PD and 35.29％ (12/34) in conditional PD group respectively (P =0.036).2 patients were met RIFLE(risk,injury,failure,loss,and end-stage renal disease,RIFLE)classification as failure grade in early PD group while 10 patients in traditional PD group (P =0.001).After PD treatment 24hrs,the Vasoactive-Inotrope Scores and serum creatinine values were much lower in the early PD group children than those in the traditional PD group[(19.00 ±2.39) vs(37.00±5.22),P=0.002;(50.51 ±21.84) vs(130.13±76.09),P=0.001)].Conclusion This study shows that early PD can prevent the children after congenital heart surgery to develop AKI,and reduce the severity of the clinic status.Early intervention with PD is associated with low mortality.

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 clinical features of invasive pneumococcus disease (IPD) with resistance to antimicrobial agents in children,and to improve the diagnosis and treatment of this disease.Methods The clinical data from 21 IPD patients younger than 13 years old were collected from January 2008 through December 2010 in Pediatric Intensive Care Unit in Beijing Children's Hospital for retrospective analysis. Specimens of blood,pleural effusion,cerebrospinal fluid and soft tissue aspirated were collected from these children,and 23 strains of streptococcus pneumonia (SP) were cultured,isolated and confirmed,and the antibiotics susceptibility to penicillin and other antibiotics of these strains were assayed.Results Among the 21 IPD children,the ratio of male to female was 0.9∶1,and the age was 5 months to 13 years,with 61.9％ of them under 2 years.Of them,12 patients (57.1％ ) had purulent pleurisy,and 1 (4.8％ )patient had an underlying disease diagnosed to be X - linked agammaglobulinemia (XLA).There was no seasonal difference in the occurrence rate of this disease. Eight (38.1％) patients were cured,11(52.4％ ) were improved,while 2 (9.5％ ) patients not improved without death.There was no statistically significant difference in the annual detection rate of invasive SP (x2 =3.711,P =0.156).The incidences of penicillin-intermediate susceptibility SP (PISP) and penicillin-resistant SP (PRSP) were 47.8％ and 26.1％ respectively.The rate of resistance to multiple antibiotics was 91.3％.Conclusions Children aged less than 5 years,especially younger than 2 years,are prone to IPD,and purulent pleurisy and septicemia are often seen in this disease. Some patients had the underlying diseases.The complications included hemophagocytic syndrome,acute respiratory distress syndrome,septic shock,bronchial pleural fistula and so on.The multidrug resistance rate was 91.3％.It is important to put great emphasis on the monitoring antibiotics resistance to invasive pneumococcal disease.

[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.
