Objective To explore the effect of positive end expiratory pressure (PEEP) on arterial oxygenation and intrapulmonary shunt during one-lung ventilation (OLV) and pulmonary function during perioperation. Methods Forty patients with normal pulmonary function,ASA I - II :scheduled for pulmonary lobectomy, were divided into control group and PEEP group by random digits table with 20 cases each. Patients were induced by double-lumen tubes under intravenous anesthesia and were received 10 ml/kg tidal volume, 12 frequents/min breathing rate during the two-lung ventilation (TLV), secondary reduced to 6 ml/kg tidal volume, 16-18 frequents/min breathing rate without PEEP (control group) or with 5 cm H2O cm H2O =0.098 kPa) PEEP (PEEP group) during OLV.Hemodynamics and respiratory mechanical parameters were continuously monitored, lung function before operation and at 72 h after operation was detected. Results Compared to before OLV,arterial oxygen tension (PaO2), arterial oxygen saturation (SpO2), oxygenation index (OI) were decreased and intrapulmonary shunt ratio (Qs/Qt) was increased in control group and PEEP group at 30 min after OLV (P < 0.01 or < 0.05). However,PaO2 and SpO2 and OI were higher and Qs/Qt was lower in PEEP group than that in control group at the same time point (P<0.05). In addition, FEV1%, FVC% and FEV1/FVC were (121.8 ± 25.0% ,(117.2 ± 24.3)% , (87.6 ± 15.7)%before operation and (84.9 ± 21.6)%, (77.2 ± 18.3)% , (70.5 ± 12.5)% at 72 h after operation respectively in control group, (116.9 ±24.5)% , (112.1 ±23.6)% , (85.3 ± 13.8)% before operation and (96.3 ± 20.4)%, (88.1 ± 19.8)% , (78.4 ± 10.2)% at 72 h after operation respectively in PEEP group. Although decreased in control group and PEEP group at 72 h after operation comparing with preoperation (P< 0.01 or < 0.05 ), FEV1%, FVC% and FEV1/FVC were higher in PEEP group than those in control group at 72 h after operation (P<0.05). Conclusion Appropriate PEEP increases arterial oxygenation,reduces Qs/Qt and improves pulmonary function during OLV,reduces the risk of hypoxernia and lung injury induced by OLV during perioperation.

Objective To evaluate the relationships of the serum levels of matrix metalloproteinase-9 (MMP-9), intercellular adhesion molecule-1 (ICAM-1) and adiponectin with the mild cognitive impairment (MCI) in senile metabolic syndrome (MS)patients. Methods The 74 cases with MS and 30 health controls (control group) were enrolled. Mini-mental state examination (MMSE), montreal cognitive assessment (MoCA), digit-symbol test (DST), auditory verbal memory test (AVMT), trail making test(TMT), sunderland clock drawing test (CDT) and verbal fluency test (VFT) were applied to evaluate cognitive function. Based on the cognitive assessment, MS patients were divided into two groups: 39 cases with MCI (MS+MCI group) and 35 cases without cognitive impairment (MS group). The levels of MMP-9, ICAM-1 and adiponectin were measured by ELISA. Biochemical variables were measured by routine methods in all subjects. Results (1)MS+MCI group showed the higher levels of BMI, SBP, FBG and MMP-9 (all P＜0.05) and lower level of adiponectin (P＜0.05) than did the MS group. And MS group had higher levels of MMP-9 and ICAM-1 (P＜0.01) and lower adiponectin level (P＜0.01) than did the control group. (2)Spearman's correlation analysis showed that the serum levels of MMP-9 (r=-0.794, P＜0.001) and ICAM-l (r=-0.501, P＜0.001) were negatively correlated with adiponectin. However, MMP-9 was positively correlated with ICAM-1 (r=0.481, P=0.006). (3)Multiple linear regression analysis indicated that there was linear relationship of MoCA with MMP-9 (β=-3.438, P=0.0019), adiponectin (β=1.337, P=0.006), SBP (β=-0.058, P=0.003) and FBG (β=-0.227, P=0.049). (4)Stepwise logistic analysis showed that both high MMP-9 (OR=1.007) and low adiponectin (OR=0.359) were risk factors for the decline of cognitive function. Conclusions Elderly patients with MS may show deterioration in memory, calculation and visuospatial perception. Elevated inflammatory factors might contribute, in combination with abnormal metabolism, to MCI. MMP-9 might contribute to neuronal degeneration. However, adiponectin could strongly counteract the risk factors for cognitive impairment.
