Objective To study the effect of mechanical ventilation guided by esophageal pressure on hemodynamics and oxygen metabolism of severe acute pancreatitis (SAP) swine model with intra-abdominal hypertension (IAH) Methods By self-controlled study,SAP model was made by infusing sodium taurocholate (5%) into the pancreatic duct in 6 domestic swine.Mechanical ventilator mode was volumeassist control with tidal volume 10 ml/kg ; FiO2 40% and PEEP 5 cm H2O (routine ventilation) given to SAP model swine.After 3 h ventilation,pneumo-peritoneum was made with N2 gas to increase the intraabdominal pressure (IAP) to 25 mm Hg in SAP swine.Three more hours later,PEEP was adjusted as the measurement of esophageal pressure (Pes guided ventilation) to such a level that trans-pulmonary pressure stayed above 0 cm H2O during end-expiratory occlusion.During the investigation period,heart rate (HR),cardiac output index (CI),central venous pressure (CVP),mean arterial pressure (MAP) and pulmonary arterial wedge pressure (PAWP) were continuously recorded with the aid of Swan-Ganz catheter and ECG monitor,and oxygen partial pressure of artery (PaO2) and carbon dioxide partial pressure of artery (PaCO2) were measured by blood-gas analysis.In addition,systemic oxygen delivery (DO2) and systemic oxygen consumption (VO2) were calculated by using the data of blood-gas analysis of arterial and central venous blood.Results No swine model was subjected to barotrauma.After routine mechanical ventilation,there were significant differences in HR,CI,MAP,CVP,PAWP,Ppeak,Pplat,Pes,pulmonary compliance (Cstat),PaO2,and DO2 between SAP and IAH in swine (all P < 0.05).Compared with routine ventilation,however,PaO2 and Cstat improved significantly with lower CI and increased Pplat after PEEP adjusted according to measurements of esophageal pressure (all P < 0.05).The lactate decreased significantly after esophageal pressure guided ventilation (all P < 0.05).There were no significant changes in PaCO2,HR,MAP,CVP and PAWP in IAH swine after mechanical ventilation with routine parameters (all P > 0.05).Conclusions There were remarkable effects on oxygen metabolism in response to mechanical ventilation guided by esophageal pressure.In case of clinical application of mechanical ventilation,the results of this study are in favor of setting transpulmonary pressure according to measurements of esophageal pressure in SAP patients with IAH in an early stage.

OBJECTIVE: To explore the influence of psychological factor on asthma, the protective and therapeutic effects of Shugan Lifei Recipe on rats with asthma under stress and the mechanisms. METHODS: Allergy and stress-induced asthma models were established in rats by giving ovalbumin and restraining stress. Radioimmunoassay, enzyme linked immunosorbent assay, in situ hybridization and immunohistochemical method were used to detect plasma corticosterone, IL-4, IFN-gamma, expression of glucocorticoid receptor (GR) mRNA in hippocampus and adrenocorticotropic hormone corticoliberin (CRH) positive neuron in hypothalamus. Optical and electron microscopes were used to observe the morphological changes of pulmonary hilar and hippocampal tissues. RESULTS: Shugan Lifei Recipe (SGLFR) could reduce plasma corticosterone, decrease CRH positive neurons in paraventricular nucleus of hypothalamus, up-regulate the expression of GR mRNA in hippocampus and reduce the injury of hippocampal neuron. SGLFR had certain inhibitive effect on hyperfunction of hypothalamo-pituitary-adrenal cortex (HPA) axis in rats with asthma under stress and could also relieve the pathological changes of the pulmonary hilar tissue. The level of plasma IFN-gamma was increased while the level of plasma IL-4 was decreased in SGLFR-treated group. CONCLUSION: The mechanism of SGLFR in treating the rats with asthma under stress is probably to regulate the hyperfunction of HPA axis and the disorder of immuo-system.
