Objective:To evaluate the clinical value of combined detection of ischemia modified albumin(IMA), N-terminal pro brain natriuretic peptide(NT-proBNP) and dynamicelectrocardiogram(DEG) in the diagnosis of silent myocardial ischemia.Methods: IMA, NT-proBNP and DEG of 114 patients with silent myocardial ischemia who were suspected coronary heart disease were detected, and then these results were compared and analyzed with the results of coronary angiography(CAG).Results: In 114 patients with suspected coronary heart disease, 68 cases(59.65％)were positive as the results of CAG. And there were 60 cases were positive as the results of IMA detection, and the specificity and sensitivity of IMA compared with CAG were 82.61％ and 88.24％, respectively. There were 63 cases were positive as the results of NT-proBNP, and the specificity and sensitivity of NT-proBNP compared with CAG were 80.43％ and 92.64％, respectively. There were 57 cases were positive as the results of DEG, and the specificity and sensitivity of DEG compared with CAG were 86.96％ and 83.82％, respectively. While there were 66 cases were positive as the combined detection of the three methods, and specificity and sensitivity of the combined detection compared with CAG were 95.65％ and 97.06％, respectively. Therefore, the specificity and sensitivity of combined detection were significantly higher than that of alone detection of IMA, NT-proBNP and DEG (F=140.637,F=255.467,P<0.05).Conclusion: The comprehensive analysis for the combined detections of IMA, NT-proBNP and DEG can increase both of the specificity and sensitivity of diagnosis, and it can be used as a important screening method for earlier finding silent myocardial.

Objective To investigate the mechanism of Glutathione in the prevention of ventilator-associated lung injury.Methods 30 mechanical ventilation patients who were healthy before were selected and randomly divided into the two groups.Group A was the high tidal volume group:10mL/kg;group B was used the tidal volume plus the injection of Glutathione(2.4g/d).After 48 hours,we collected lavage fluid and use Coomassie brilliant blue to detect the protein content of alveolar lavage fluid of the two groups.Results There was a significant difference (P<0.01)between the two groups.The protein content in group A[(9.90 ±2.25)g/L]was higher than that of group B [(4.17 ±0.39)g/L],and there was statistically significant (P<0.01).Conclusion Glutathione can reduce the incidence of ventilator-associated lung injury and prevent the occurrence of ventilator-associated lung injury.

Objective To assess the effect of variable durations of warm ischemia on renal function early after laparoscopic partial nephrectomy ( LPN ) and make the definite safety duration of renal warm ischemia.Methods The clinical data of 76 patients treated with LPN from October 2012 to June 2014 were retrospectively analyzed.The patients were divided into 3 groups based on warm ischemic time,namely group A (28 cases) with warm ischemia time less than 20 min,group B (34 cases) with warm ischemia time more than 20 min and less than 30 min, group C ( 14 cases ) with warm ischemia time more than 30 min.LPN was performed with renal artery clamping alone in all the patients.Preoperative and postoperative renal scintigraphic scan was performed to access glomerular filtration rate ( GFR) in all patients.The GFR values were compared among before, 1 week, 1 month and 3 months after operation.The factors predicting the early renal injury were assessed by multivariate regression analysis.Results The renal GFR of the kidney underwent LPN decreased 19.43(17.70,22.06) ml/min at 1 week,17.04(13.94,20.70) ml/min at 1 month,13.82(10.72,18.73) ml/min at 3 months after the surgery in group C,respectively.In group A, the renal GFR of the operated-side decreased 12.07(10.91,13.42) ml/min,10.04(9.16,11.75) ml/min, 8.44(7.07,9.72) ml/min,respectively.In group B, the renal GFR of the operated-side decreased 13.64 (12.48,16.72) ml/min,10.29(9.17,14.27)ml/min,9.63(7.85,12.59) ml/min,respectively.The GFR decreased greater in group C than that in group A and B(P<0.05).The total renal GFR decreased (10.70 ± 4.93)ml/min at three months in group C,compared with (5.64 ±4.12)ml/min in group A and (6.37 ± 4.32)ml/min in group B,respectively.The decreased value in group C was greater than that in group A and B(P<0.05).However,the differences of the total renal GFR among the 3 groups were not significant at 1 week and 1 month(P>0.05).The multivariate regression analysis revealed that warm ischemia duration was the independent risk factor of the early renal injury.Conclusions Warm ischemia duration is the major factor regarding the early renal recovery after LPN.Warm ischemia time more than 30 min may not only greatly affect the renal function but also the renal function recovery rate.
