Objectives To investigate the effect of rhEPO on newborn rats with necrotizing enterocolitis (NEC). Meth-ods Sixty newborn Sprague-Dewley (SD) rats at the age of 48 hours were randomly divided into 5 groups:control group, NEC group, and intervention groups 1, 2 and 3 treated with rhEPO. The rats were fed rat breast milk substitutes and stressed under hypoxia and cold exposure to establish NEC model. The rats with NEC were treated with different doses of rhEPO (0.1U/ml, 1U/ml and 10U/ml) in intervention groups. The expression of Bcl-2 and caspase-3 were measured by immunohistochemistry, and intestinal pathological changes were observed using HE staining. The value of positive expression was analyzed by IOD (integral optical density) image analysis system. Results Abdominal distention, decreased activity and unresponsiveness occurred in NEC rats 24 hours after stress exposure, and pale skin, decreased skin temperature and respiratory rhythm change were observed in severe cases. The symptoms appeared later and milder in three intervention groups. The NEC incidence of newborn rats was as followings:control group(0%), model group(60%), intervention group 1( 30%), intervention group 2(18.2%), intervention group 3(9.1%) and the difference was signiifcant between each group (P=0.008). The grades of intestinal injury, the expression of active caspase-3 and Bcl-2 were signiifcantly different among groups (P<0.01). Intestinal injury was the most severe and the expression level of active caspase-3 was the highest in NEC group. After rhEPO treatment, the intestinal injury and the production of active caspase-3 protein were decreased, and the expression of Bcl-2 was increased. Conclusions Oral rhEPO could decrease the ex-pression of intestinal active caspase 3, and increase the expression of Bcl-2. The protective effect of rhEPO on NEC is dosede-pendent.

Objective To determine the sites of action of propofol and isoflurane on somatosensory pathway using median nerve somatosensory evoked potential(MnSSEP) .Methods Twenty-six ASA I - II patients aged 20-50 yrs were randomly divided into two groups: I propofol group( n = 13) and H isoflurane group( n = 13) .In propofol group patients received propofol infusion at a rate of 10 mg?kg-1?h-1 .Oxygen was administered via mask and respiration was assisted or controlled to maintain SpO2 at 96%-100% and PETCO2 at 35-45 mm Hg. The propofol infusion was continued until the patient failed to respond to verbal command. Six minutes later if the patient was still breathing spontaneously, the rate of propofol infusion was increased to 20-40 mg?kg-1?h-1 . In isoflurane group anesthesia was induced with propofol 2 mg ? kg-1 and intubation was facilitated by succinylcholine and anesthesia was maintained with isoflurane inhalation and intermittent iv boluses of vecuronium. The end-tidal isoflurane concentration was maintained at 0.5,1.0 and 1.5 MAC. Each concentration was maintained for 15 minutes. MAP, HR, SpO2,PCTCO2, T0(naso-pharyngeal) and BIS were continuously monitored. MnSSEP( Viking IV D type) was measured and recorded before induction of anesthesia(baseline) and in propofol group when patients became unconscious and apneic; in isoflurane group when end-tidal isoflurane reached 0.5,1.0 and 1.5 MAC.Results In group I there was no change in both latencies and amplitudes of N9 and N13'.With increasing infusion rate, propofol gradually prolonged the latencies and decreased the amplitudes of N60, P45, N35, N20 and P25 waves. In isoflurane group there was no change in the latencies and amplitudes of N9. There was no change in the latencies of N13', but the amplitudes decreased at 1.0 and 1.5 MAC. With increasing concentration, isoflurane gradually prolonged the latencies and decreased the amplitudes of P45, N60, N35, N20 and P25 waves. At 1.5 MAC the inter-peak latencies between N13'-N20 and N13'-P25 were prolonged. Conclusions The sites of action of different infusion rates of propofol and different concentrations of isoflurane are different on somatosensory pathway. The higher the doses, more widespread are the sites of action.

Objective To investigate the effect of Sufentainil on myocardial ischemia-reperfusion injury and caspase-3 to rat heart. Methods Ninety Wistar rats weighing 200-300g were randomly divided into 3 groups(n=30):sham group(group S), ischemia-reperfusion group (group I/R)and Sufentainil group (group SF). Each group was divided into 3 subgroups according to the time phases at 30, 60 and 120min(n=10).In group I/R and group S the animals were received normal saline intravenously. In group SF sufentainil 5μg/kg NS 20ml was given. After 24 h, all animals were anesthetized with intraperitioneal 20% urethane 1 mg/kg, intubated and mechanically ventilated. The chest was opened and heart exposed via thoracotomy.In group S , left artery anterior descending artery(LAD) was not ocluded. While in I/R and SF group myocardial ischemia was introduced by clamping LAD for40 min. The animals were killed at 30, 60 and 120 min of reperfusion respectively(n=10each). Cardiac tropoin I(cTnI), expression of caspase-3 and apoptosis of cell in heart tissues were measured at the same time.Ultrastructure of myocardium taking the from apex was examined by electron microscopy at the end of 120 min reperfusion. Results Compared with group S, the concentration of cTnI was increased in the other 2 groups(P<0.05).cTnI was significantly lower in group SF than in group I/R(P<0.05). Expression of caspase-3 and apoptosis index induced by myocardial reperfusion were attenuatated in group SF(P<0.05). The damage of myocardial ultrastructure caused by myocardial I/R were also significantly improved in group SF. Conclusion Sufentainil may relieve the heart cellular apoptosis by decreasing caspase-3expressing.
