Objective To investigate the effect of erythropoietin (EPO) on the expression of MMP-2 in hippocampus of neonatal rats after hypoxic-ischemic brain damage (HIBD), and the mechanism of its neuroprotective effect. Methods Neonatal Sprague-Dawley rats of 7 days old were randomly divided into three groups (n?=?48 in each group): sham-operated group, HIBD group and EPO treated group, then each group was further divided into four subgroups (n?=?12) based on different time points following the injection of medication ( 6 h, 24 h, 3 d, 7 d). The expression of MMP-2 in hippocampus was determined by immunohistochemistry and real-time lfuorescent quantitative PCR method. Results Immunohistochemistry: MMP-2 has a small amount of expression in the hippocampus of the sham-operated group, and at each time point, there is no statistically signiifcant difference (P?>?0.05);The expression of MMP-2 in HIBD group and EPO group all show a trend of increase, and peaked at 7 d, the differences between each time point in two groups are statistically signiifcant (P??0.05). Gene expression in HIBD group at 24 h and 7 d points showed twin peaks, and the peak is higher at the 7 d point, but without difference (P?>?0.05). MMP-2 expression of EPO group presents a trend of increase, and differences are signiifcant between each time point (P?

Objective To investigate the effects of rapid colloid and crystalloid infusions on the plasma concentration of propofol( Cp) during target-controlled infusion.Methods Thirty-six patients were randomly assigned to three interventions(12 patients per group).At least 30 min after the start of propofol infusion,the hydroxyethyl starch solution group(HES)received HES of 24 mL/(kg· h),on the former 20 min,the sodium acetate Ringer’s injection group(AR)received AR of 24 mL/(kg· h),while HES group and AR group of later 20 min and the control group of whole course received AR of 2 mL/(kg· h).The plasma concentrations of propofol were recorded per 2 min and a half.The cardiac outputting,blood volume and clearance of indocyanine green were measured by pulsed dye density analyzer,the effective hepatic blood flow( EHBF) were obtained.Results The varying of Cp with time showed a significant treatment factor(F[2,33] =14.14,P<0.001)and time factor(F[16,528] =10.37,P<0.001)and interaction between the above factors(F[32,528] =2.82,P <0.001) by ANOVA for repeated measurement;the difference of Cp among each group,Cp in HES group was significantly lower than AR group(5-40 min)or control group(10-40 min),with significant difference(P<0.05).The varying of EHBF with time showed a significant treatment factor(F[2,28] =3.68,P=0.038)and time factor(F[2,56] =5.37,P=0.007)and interaction between the above factors(F [4,56] =3.67,P=0.010);while there was no significant difference in other groups.Conclusion Rapid HES infusion increases the effective hepatic blood flow,resulting in a decrease of propofol concentration during target-controlled infusion.Rapid HES infusion should be used cautiously as it may decrease the depth of anesthesia.

Objective To observe the effect of restrictive transfusion in colon cancer surgery in elderly patients on postoperative VAP (ventilator-associated pneumonia). Methods Forty cases of elderly patients with colon cancer intending to undertake surgery were randomly divided into restrictive transfusion group (group R) and standard transfusion group (group S) with 20 cases in each group. In group R, patients were administered one third of accumulative fluid loss in the first 60 minute, then the infusion rate were 4 mL/(kg·h) and central venous pressure was maintained at 5 ~ 7 cmH2O. In group S, rate of fluid administration = CVE + deficit +maintenance + loss + third space. Blood gas index including lactic acid and volumes of fluid administered, blood loss, urine volume and thoracic fluid count (TFC) were recorded in the operation. Clinical pulmonary infection score(CPIS) was recorded respectively before operation, 1 day, 3 day, 7 day after operation to evaluate the risk of VAP. Results Compare with those in group S, there were significantly less TFC and intraoperative volumes of fluid administration in group R. The CPIS was significant lower at day1, day3, day7 after operation in group R. There was no significant difference in MAP, HR, CO and urine volume between two groups. Conclusions In colon cancer surgery for elderly patients, restrictive transfusion can maintain hemodynamic stability, ensure the tissue oxygenation, reduce conjunction edema, shorten the recovery and hospital stay and reduce the incidence of VAP.

OBJECTIVETo study clinical effects of inversive LISS (less invasive stabilization system, LISS) plate combined with steel wire for the treatment of Seinsheimer type V subtrochanteric femoral fractures.

METHODSFrom January 2009 to Janurary 2012, 11 patients with Seinsheimer type V subtrochanteric femoral fractures were treated with inversive LISS plate combined with steel wire, including 8 males and 3 females, ranging in age from 35 to 61 years old (averaged, 51 years old). Causes of injury: 8 patients caused by accident and 3 patients caused by falling down. According to X-ray examination, all the patients were type V subtrochanteric femoral fractures and were treated with LISS plate combined with steel wire. Merle d'Aubigne scores were used to evaluate therapeutic effects on hip.

RESULTSThe mean period of follow-up was 16 months (ranged, 12 to 28 months). All the patients obtained bone union for average 3.8 months (ranged from 3 to 4.3 months). There were no complications such as deep infection,deep vein thrombosis, pulmonary embolism and bone nonunion. According to Merle d'Aubigne scores, 7 patients got an excellent result and 4 good.

CONCLUSIONInversive LISS plate combined with steel wire for the treatment of Seinsheimer type V subtrochanteric femoral fractures is satisfactory, Which can provide stable fixation for fracture end and provide an ideal internal fixation method for treatment of this kind of fractures in the future.
