Abstract
Objective: To explore the characteristics and prognostic value of pulmonary hemodynamics in patients with acute coronary syndrome (ACS). Methods: From a prospective multicenter registry study of pulmonary hypertension due to left heart disease, consecutive ACS patients who underwent coronary angiography in combination with left and right heart catheterization during hospitalization between January 2013 and November 2016 were involved. The primary endpoint was all-cause mortality. The prognostic variables identified by the Lasso analysis were included in the Global Registry of Acute Coronary Events (GRACE) score. Model performance was evaluated before and after the addition of hemodynamic parameters. Results: A total of 251 patients were enrolled, with age of (63.7±11.5) years. A total of 198 males (78.9%) and 53 females (21.1%) were recruited, and the median follow-up time was 34.7 months. Right heart catheterization-assessed mean pulmonary arterial pressure (mPAP), systolic pulmonary arterial pressure (sPAP) and diastolic pressure gradient (DPG) were found to be significant predictors for survival in ACS. Adjusted for age and sex, the adjusted HR (95%CI) of mPAP, sPAP and DPG were 1.068 (1.015-1.123), 1.033 (1.002-1.065) and 1.094 (1.008-1.187), respectively (P<0.05). Applied to the present cohort of 251 patients, the median of the GRACE score was 123 points, with a C-index of 0.703 (95%CI: 0.615-0.791) for predicting mortality. After the addition of mPAP or DPG to the GRACE score, the C-index increased to 0.715 (95%CI: 0.629-0.801) or 0.711 (95%CI: 0.625-0.797), respectively. When comparing two models before and after the addition of mPAP or DPG, the integrated discriminatory index (IDI) was 4.3% (95%CI: 0.2%-13.5%, P=0.030) and 3.0% (95%CI: 0.2%-11.1%, P=0.020), respectively. Conclusion: Pulmonary hemodynamics can be predictive for survival in ACS patients, providing incremental prognostic value to risk assessment in ACS.

Abstract
The reduction in apoptosis caused by short-term exposure of CEM x174 cells infected with SIVmac239 to morphine was investigated. Eeffects of morphine on the viability of normal and infected CEM x174 cells were determined by MTS assay. Apoptosis induced by SIVmac239 and the effects of morphine were analyzed by flow cytometry. cAMP levels, PKA activity, and the resulting histone H3 phosphorylation levels were measured. The results show a pronounced decrease in numbers of infected SIVmac239 cells compared to controls. Morphine elevated cell viability in the infected groups. Annexin V binding assays showed that 1 microM l(-1) morphine increased the percentage of viable cells and decreased apoptotic cells. Morphine also downregulated cAMP and PKA activity in both groups, but more markedly in the infected group. Histone H3 phosphorylation was elevated after virus infection and decreased in the presence of morphine. The results indicate that the cAMP-PKA signal transduction cascade is involved in morphine regulation of early SIVmac239-induced apoptosis.
