Objective To observe the effect of octreotide acetate on plasma ETX and serum inflammatory cytokine of the rabbit with hepatic ischcmia reperfusion injury. Methods Pringle's maneuver rabbit hepatic ischemia-repeffusion models were established. 24 adult New Zealand rabbits were random divided into equal 3 groups: sham operative group(group A), iacbemia reperfusion group(group B)and octreotide acetate preconditioning group(group C). Endotoxin (ETX) in the plasma, tumor necrosis factor-alpha (TNF-α) and intcdeukin-1beta (IL-1β) were detected in every rabbit at the time before iachemia (T1), 30min after ischemia (T2), 30min (T3) and 120min (T4) after reperfusion. Results From T2 to T4, the ETX in group B and C were higher than that in group A (P < 0.05), the ETX of group C were lower than that in group B (P<0.05). From T2 to T4, the TNF-α of group B and C were higher than that of group A(P<0.05). From T3 to T4 the TNF-α of group C were higher than that of group A(P<0.05). From T2 to T4,the IL-1β of group B and group C were higher than that of group A(P<0.05), and the IL-1β of group C were lower than that of group B (P<0.05). Conclusion Octreotide acetate can decrease plasma ETX and down-regulate inflammation factors, such as TNFαand IL-1β, in serum of the rabbit with hepatic iacbe-mia-reperfusion injury, which may be the protective mechanism of oetreotide acetate on rabbit hepatic isehemia-reperfusiun injury.

Objective：To explore influence of viable myocardium in myocardial infract region on left ventricular remodeling and left cardiac function in diabetic patients with acute myocardial infarction (AMI) after percutaneous coronary intervention (PCI). Method: A total of 208 patients with type 2 diabetes mellitus (T2DM) complicated AMI after PCI underwent myocardial metabolic imaging by 18F- deoxyglucose position emission tomography (18F-FDG PET) and myocardial perfusion imaging by 99mTc-methoxy isobutyl isonitrile single photon emission computed tomography (99mTc-MIBI SPECT). According to whether there was viable myocardium in myocardial infarct region, patients were divided into viable myocardium group (n=115，perfusion didn’t match metabolism) and no viable myocardium group (n=93, perfusion matched metabolism). Indexes of echocardiography were measured in two groups before and after PCI. Influence of viable myocardium in myocardial infarct region on left ventricular remodeling and cardiac function was observed. Result: After myocardial infarction 12 months, compared with no viable myocardium group, there was significant increase in left ventricular ejection fraction (LVEF) [(44.1±7.12)% vs. (46.7±6.98)%] and significant decrease in left ventricular end-diastolic dimension (LVEDd) [ (55.46±4.75) mm vs. (53.17±4.77) mm], left atrial diameter [ (39.25±11.31) mm vs. (35.89±12.08) mm] in viable myocardium group, P＜0.05 all. There were no significant difference in ratio of mitral diastolic peak flow velocity (E/A) in two groups after 12 months (P＞0.05). Conclusion: In patients with type 2 diabetes mellitus complicated acute myocardial infarction, compared with no viable myocardium patients, LVEF significantly improves, LVEDd significantly decreases in patients with viable myocardium within myocardial infract region.

Objective To evaluate the effects of remifentanil on the proliferation,the cell cycle and apoptosis of human liver carcinoma cell line HepG2 in vitro.Methods Human liver carcinoma cells HepG2 were cultured in vitro.The HepG2 cells of the test group were incubated in the RPMI-1640 medium with remifentanil at different concentration(0.001,0.01,0.1,1,10,100,200 μmol/L).The HepG2 cells of the control group were incubated in the RPMI-1640 medium for 48 hours.The level of the cell proliferation was evaluated with methylthiazolyldiphenyl-tetrazolium bromide (MTT) method.The cell cycle was detected with flow cytometry (FCM).The morphological change of apoptosis cell was observed by fluorescence microscopy after staining by Hoechst33258.Results Remifentanil inhibited the proliferation of the HepG2 cells with a dose-dependent effect.Compared with control group,the cell proliferation capability was apparently decreased in the test group (P ＜ 0.05) when the concentration of remifentanil was over 1 μmol/L (P ＜0.05).However,no significant difference in cell proliferation was found when remifentanil was 100 and 200 μmol/ L.The ratio of G0/G1 phase of HepG2 cells was significantly enhanced and the ratio of S phase of HepG2 cells was significantly decreased when remifentanil was over 1 μmol/L.The fluorescent microscopy stained by the Hoechst33258 showed part of HcpG2 cells apoptosis in test group,and the apoptotic rate was significantly increased when remifentanil was over 1 μmol/L (P ＜ 0.05).Conclusions The data suggest that remifentanil would inhibit the proliferation of HepG2 cells and induce apoptosis when remifentanil was over 1 μmol/L.

Objective To investigate the acute toxicity and anti-stress effects of Naoxinshu capsule (NC) in mice.Methods In acute toxicity experiment,mice were oral administered to determine the maximum tolerance dose of NC.In anti-stress experiments,mice were divided into 5 groups at random,namely NC high,medium and low dose groups (2.4,1.2 and 0.6 g/kg,respectively),Gypenosides group(0.75 g/kg) and control group (n=10).After seven days of oral administration,rope climbing time,loaded swimming time,anti-hypoxia time,and survival rate under high or low temperature tests were carried out,respectively.Results The maximum tolerance dose of NC was 72 g/kg.NC high,medium and low dose groups significantly prolonged the rope climbing time [is (9.5 ± 3.1) min,(6.0± 1.6) min,(4.1 ± 1.2) min],loaded swimming time [is (28.2± 6.8) min,(25.7± 10.3)min,(22.9± 8.0)min] and anti-hypoxia time (around 17 min),compared to the control group (P＜0.05 or P＜0.01).NC high dose group significantly improved the survival rate of mice (i.e.30％) under high or low temperature (P＜0.05).Conclusion NC shows good anti-stress effects,and no detectable acute toxicity in mice.

Objective To study the protective effect of octreotide on myocardial injury after hepatic ischemia-reperfusion in rabbit. Methods Pringle's maneuver rabbit hepatic ischemia-reperfusion model was established. 24 adult New Zealand rabbits were random divided into equal 3 groups: sham operative group ( group A) , ischemia-reperfusion group( group B) and octreotide preconditioning group ( group C ). The levels of CK-MB( MB isoenzyme of creatine kinase) and LDH ( 1actate dehydrogenase), superoxide dismutase (SOD) and malondialdehyde (MDA) of each group were measured at the time before ischemia (T1) , after ischemia for 30 mins ( T2 ) and after reperfusion for 60 mins ( T3 ), 120mins ( T4 ), 240 mins ( T5 ). The SOD and MDA in myocardial tissue of each group were measured after reperfusion for 240 mins. The changes of ultrastructure in the myocardial cell were observed by transmission electron microscopy after reperfusion for 240 mins. Results There was no significant difference in the levels of CK-MB and LDH in serum of each group before ischemia ( P ＞0. 05). The CK-MB and LDH of group B and C were higher than that of group A ( P ＜0.05) after ischemia for30 mins. The CK-MB and LDH of group C were lower than that of group B in this period( P ＜0. 05 ). The highest time point of LDH and CK-MB were after reperfusion for 120 mins and 240 mins. The contents of MDA in group B and group C were higher than that in group A from after ischemia for 30 mins in plasma and after reperfusion for 240 mins in myocardial tissue ( P ＜ 0. 05 ),and it in group C were lower than that in group B( P ＜0.05) .The contents of SOD in group B and group C were lower than that in group A from after ischemia for 30 mins in blood plasma and after reperfusion for 240 mins in myocardial tissue ( P ＜0. 05), and in group C were higher than that in group B( P ＜0. 05).The electromicroscope showed that the pathological change of myocardial ultrastructure of group C was slighter than that of group B. Conclusion Octreotide can stabilize myocardial cell membrane and reduce release of oxygen free radical and significantly relieve the injury of myocardial ultrastructure after hepatic ischemiareperfusion in rabbit. Octreotide preconditioning can relieve myocardial injury after hepatic ischemia-reperfusion in rabbit.

Objective:To investigate the effects of sodium aescinate on endothelin ( ET ) and calcitonin gene -related peptide ( CGRP) contents in the gerbils with cerebral ischemia/reperfusion injury ( CI/R) . Methods:The gerbil model of CI/R was prepared by bilateral common carotid arteries ligation for 10 min followed by 2-hour reperfusion. Sodium aescinate (i. p. , 10, 20 and 40 mg· kg-1 ) was administered once a day for 3 days before the operation and once every 1 h after the operation, respectively. The levels of ET and CGRP in brain tissue homogenate were determined by a radioimmunoassay method. Results:Sodium aescinate significantly in-hibited the level of ET (28. 69-37. 03 ng·L-1) in the brain tissue of gerbils with CI/R compared with the model group (P<0. 05 or P<0. 01), while showed no evident influence on CGRP (P>0. 05). Conclusion:Sodium aescinate has obvious protective effects a-gainst CI/R in gerbils, which may be due to its inhibitory action on ET levels in brain tissue.
