Objective To investigate the effects of small tidal volume combined with PEEP on extravascular lung water during one-lung ventilation (OLV) in patients undergoing thoracic surgery. Methods Forty ASA Ⅰ or Ⅱ patients of both sexes aged 45-80 yr undergoing esophagectomy for esophageal cancer were randomly assigned into 2 groups (n = 20 each):group Ⅰ IPPV (VT 9 ml/kg ,RR 12 bpm) and group Ⅱ IPPV +PEEP (VT 6 ml/kg, RR 15 bpm, PEEP 5 cm H-2O). FiO2 was 100% and I:E 1:2 in both groups. Anesthesia was induced with fentanyl 3-5 μg/kg, propofol 1.0-1.5 mg/kg and vecuronium 0.10-0.15 mg/kg and maintained with continuous infusion of propofol 4-7 mg· kg- 1 · h - 1 and vecuronium 0.07-0.08 mg- kg- 1 · h - 1 and intermittent iv boluses of fentanyl. Double lumen endobronchial tube was inserted. Correct position was confirmed by bronchoscopy. Right internal jugular vein was cannulated. A 4F thermodilution catheter was inserted into right femoral artery and connected to PICCO monitor. Extravascular lung water (EVLW), EVLW index (EVLWI),pulmonary vascular permeability index (PVPI), cardiac output (CO) and oxygenation index (OI) were recorded before anesthesia (T0, baseline), at 30 min of two lung ventilation (T1), 30 min and 1 h of OLV (T2, T3),before extubation (T4) and 18 h after operation (T5). Airway peak pressure (Ppeak) was recorded at T1-4. Results EVLWI and PVPI were significantly higher in group IPPV + PEEP than in group IPPV. There was no significant difference in Ppeak, CO and OI at any time point between the 2 groups. In group IPPV there was no significant change in EVLW and EVLWI during and after mechanical ventilation, while PVPI was significantly increased at T1 as compared with the baseline before anesthesia. In group IPPV + PEEP EVLW was significantly increased at T2 and PVPI was significantly increased at T1 and T2 compared with the baseline at T0. Conclusion OLV with IPPV + PEEP results in more EVLW and it exerts no significant effect on lung function.

Objective To investigate the involvement of Bcl-2 and Bax mRNA expressions in mitochondrial toxin 3-nitropropionic acid(3-NPA)induced ischemic tolerance to focal cerebral ischemia in rats.Methods Rats were administrated 3-NPA intraperitoneally at dose of 20 mg/kg 3 days prior to a 2 h middle cerebral artery occlusion followed by 1 h,6 h,12 h,24 h and 48 h of reperfusion.The Bcl-2 and Bax mRNA expressions were measured by reverse transcriptase polymerase chain reaction and compared to the sham operation group and ischemic reperfusion group.Results Compared to the sham operation group,the ischemic reperfusion and 3-NPA pretreated groups exhibited an increase in Bcl-2 and Bax mRNA after reperfusion every time point of focal cerebral ischemia(all(P

AIM:Nitroxyl ( HNO) increases myofilament Ca 2+responsiveness relative to increases in intracel-lular Ca2+in cardiac muscle.In this study, we further investigated this effect of HNO on trabecular muscles from phospho-lamban knockout ( PLB-KO) and wide-type ( WT ) mice using a novel HNO donor , 1-nitrosocyclohexyl acetate ( NCA ) . METHODS:Trabecular muscles were dissected from the right ventricles of the rat hearts and mounted between a force transducer and a motor arm.The muscles were superfused with K-H solution (pH 7.4) at room temperature.Fura-2 was loaded into the trabecular muscles via electrophoresis .The length of the sarcomere was set to 2.2~2.3μm.During stead-y-state activations, the maximal Ca2+-activated force and Ca2+required for 50% activation were measured.RESULTS:The intracellular Ca 2+transients and force of the PLB-KO muscles at baseline were higher than those of the WT muscles and exhibited a negative force-frequency relationship (FFR).NCA (2.5μmol/L) increased systolic force in both PLB-KO group and WT group at any given [Ca2+]o.However, there was more dramatic increase in the force development due to moderate increases in the intracellular Ca 2+transients in the WT muscles when external Ca 2+increased from 1.5 to 4.5 mmol/L under NCA.NCA did not affect the negative FFR in PLB-KO muscle.Steady-state force-Ca2+relations obtained from skinned muscles were not different between the 2 groups, while NCA increased Ca2+responsiveness in skinned mus-cles from both PLB-KO and WT mice.CONCLUSION:HNO increases force development in both PLB-KO and WT mus-cles as a result of increases in myofilament Ca 2+responsiveness .The increased intracellular Ca 2+transients are accompa-nied by greater force development in WT mice , suggesting that HNO improves Ca 2+activation and establishes HNO as a positive inotropic agent with novel mechanisms .

OBJECTIVE: To investigate the effects of heterogenous suberect spatholobus stem (Spatholobus suberectu, Mucuna birdwoodiana, Millettia oosperma and Millettia dielsiana) on peripheral blood cell counts of mice with bone marrow suppression induced by (60)Co gamma ray irradiation. METHODS: Bone marrow suppression was induced by sublethal dose of (60)Co gamma ray in mice. White blood cell (WBC), red blood cell (RBC) and platelet (PLT) counts in peripheral blood of the mice were detected one day, 3, 7, 14 and 21 days after intragastric administration of different doses of the four kinds of suberect spatholobus stem, respectively. RESULTS: A slowdown of the decrease of WBC, RBC and PLT counts in peripheral blood of the mice with bone marrow suppression was observed after intragastric administration. The WBC, RBC and PLT counts in the Mucuna birdwoodiana-treated and Spatholobus suberectu-treated groups were significantly higher than those in the untreated group (P<0.05). CONCLUSION: All the four kinds of heterogenous suberect spatholobus stem can accelerate the recovery of WBC, RBC and PLT counts in peripheral blood of mice with bone marrow suppression, while the effects of Spatholobus suberectu and Mucuna birdwoodiana are relatively good.
