Objective To investigate the effect of propofol preconditioning on activities of ATPase on myocardial cell membrane in rats with myocardial ischemia-reperfusion injury. Methods Forty Sprague-Dawiey rats were subject to 30 min ischemia and 60 min reperfusion and randomly assigned to five groups, six rats per group: control(C) group; ischernia-reperfusion (IR) group; propofol preconditioning group(P, according to the dosage of propofol, P was assigned to three KM+-ATPase and Ca2+-Mg2+-ATPase of left ventricle myocardial tissue were measured by chemical colorirnetric method. The rnyocardium pathomorphism was observed with light microscopes. Results The activities of Na+-K+-ATPase and Ca2+-Mg2+-ATPase in ischemia-reperfusion group were lower than control group and propofol preconditioning group(P<0. 05 or P<0.01). Conclusion Propofol preconditioning can produced cardioprotective effect against ischemia-reperfusion injury by recovering the ATPase activities of myocardial tissue.

To study the effectiveness of combined Acupuncture and Chinese medicine on depression. Methods: Ninety-eight patients were randomly divided into two groups. The treatment group of 52 cases were treated by scalp acupuncture and electroacupuncture, Baihui (GV 20), Shenting (GV 24), Taichong (LR 3), Neiguan (PC 6),Guanyuan (CV 4), Zusanli (ST 36), Sanyinjiao(SP 6), plus Chinese medicine, modified Xiaoyao Powder (a decoction for soothing liver and relieving depression) and the control group of 46 cases, only with Chinese medicine, modified Xiaoyao Powder. Results: The total effective rate was 94.2% in the treatment group and 78.26% in the control group; with a significantdifference between two groups(P＜0.05) Conclusion: Acupuncture plus Chinese medicine has a marked effect on depression.

Objective To compare the clinical efficacy of programmed intermittent epidural bollus (PIEB)+patient controlled epidural analgesia (PCEA)and continuous epidural infusion (CEI)+PCEA for labor analgesia.Methods One hundred nulliparous parturients with cervical dilation of 2-3 cm were randomly assigned to PIEB group or CEI group for labor,with 100 parturients in each group.The background infusion in PIEB group delivered 8 ml bolus at a rate of 6 ml/min per 1 hour, in group CEI at 8 ml/h.Blood pressure,VAS score and modified Bromage score before labor anesthe-sia (T0 ),10 min after labor anesthesia (T1 ),30 min after labor anesthesia (T2 ),1 h after labor an-esthesia (T3 ),2 h after labor anesthesia (T4 ),the uterus opening to the full extent (T5 ),childbirth (T6 ),1 h after childbirth (T7 ),proportion of PCEA request,hourly ropivacaine and sufentanil con-sumption,uterine contraction,fetal heart,total delivery time,analgesic time,delivery mode,number of cases using oxytocin,adverse reactions,neonatal Apgar score,maternal satisfaction score were ob-served.Results The VAS score of PIEB group was significantly lower than that of CEI group at T4-T6 (P <0.01).Compared with the CEI group,protortion of PCEA request,the dosage of drug was de-creased obviously in group PIEB (P <0.05),the maternal satisfaction of PIEB group was significantly higher than that of CEI group (P <0.05).There was no significant difference in the blood pressure, duration and interval time of uterine contraction,fetal heart,total delivery time,analgesic time,deliv-ery mode,number of cases using oxytocin,adverse reactions,neonatal Apgar score and weight among two groups.Conclusion Compared with the CEI+PCEA,the need of PCEA and the dosage of drug was decreased obviously,the VAS score was significantly lower,the maternal satisfaction was signifi-cantly higher and adverse reactions did not increase in the PIEB+PCEA.

In recent years , active vitamin D is a hot research drugs because of its renal protective effect of independent regu -lation of anti-inflammatory effects outside calcium and phosphorus metabolism , regulation of apoptosis , mediated immunity and reduc-tion of proteinuria .Podocyte is the main target of active vitamin D based on the result of clinical and animal studies .In this article, we review the current literature on mechanism of active vitamin D and its analogues on the protection of podocytes about and give the clini -cal perspectives of activity vitamin D .

Objective The core mechanism of renal insterstitial fibrosis (RIF) is epithelial-mesenchymal transition.This study aimed to investigate the effect of erythropoietin on high glucose-induced epithelial-mesenchymal transition ( EMT) of normal hu-man kidney proximal tubular epithelial cells (HK-2) and its possible mechanism. Mothods HK-2 cells cultured in vitro were ran-domly divided into a blank control group , a high glucose induction group , a mannitol induction group , an EPO induction group , an EPO (5, 10, and 20U/mL) inhibition group, and an Rho kinase inhibitor group.After 24 hours of intervention, the mRNA levels of RhoA and ROCK were determined by RT-PCR, those of E-cadherin and α-smooth muscle actin (α-SMA) proteins detected by immu-nofluorescence staining , and the expression of FN proteins in the supernatant measured by ELISA . Results Compared with the blank control group , the expressions of RhoA and ROCK 1 mRNA were significantly increased in the high glucose induction group (0.945 ±0.132 vs 1.400 ±0.022, 1.007 ±0.002 vs 1.913 ±0.011, P<0.05), but markedly decreased in the 5, 10, and 20U/mL EPO inhibition groups (1.400 ±0.022 vs 1.278 ±0.006, 1.400 ±0.022 vs 0.770 ±0.005, 1.400 ±0.022 vs 0.334 ±0.009, P<0.006) in comparison with the high glucose induction group , and the effects were related to the concentration of EPO .Compared with the blank control, the expression of E-cadherin protein was increased in the high glucose induction group (0.644 ±0.006 vs 0.107 ± 0.004, P<0.05), but remarkably decreased in the 5, 10, and 20 U/mL EPO inhibition groups (0.236 ±0.006, 0.433 ±0.010, 0.521 ±0.010) in comparison with the high glucose induction group (P<0.05), and the effects were also related to the concentration of EPO.Pearson correlation analysis showed a positive correlation between the mRNA expressions of RhoA and ROCK 1 in the high glu-cose induction and EPO inhibition groups . Conclusion EPO can inhibit high glucose-induced epithelial-mesenchymal transition of normal human kidney HK-2 cells and thus delay renal fibrosis , which mignt be related to the RhoA/ROCK signaling pathway .

Aim To study the effect of proteasome inhibitor MG132 on the expression of caspase-3 and apoptosis in cultured human umbilical vein endothelial cells.Methods Human umbilical vein endothelial cells was treated with MG132 (2,5 ?mol?L~(-1)) for 24 h. The apoptotic cells were determined by DNA fragment analysis and flow cytometric analysis. The level of caspase-3 mRNA was quantified by reverse transcription-polymerase chain reaction (RT-PCR). The protein contents of caspase-3 were analyzed by immunocytochemistry.Results The results showed that the increase of the degree of human umbilical vein endothelial cells apoptosis was concentration dependent. MG132 could up-regulate the gene/protein expression of caspase-3.Conclusions The results implicated that proteasome inhibitor MG132 induced human umbilical vein endothelial cells apoptosis by accumulation of caspase-3.
