RESUMEN
One hundred and nine consecutive coronary heart disease (CHD) patients with obstructive sleep apnea (OSA) undergoing percutaneous coronary intervention (PCI) during February 2016 to August 2018 were enrolled in the study. After treatment the quality of sleep was improved in 35 cases (observation group) and was not improved in 74 patients (control group). The basic characteristics, coronary lesions of patients were compared between two groups. Compared with the control group, patients in observation group had significant higher proportion of males [80.0%(28/35) vs. 59.5%(44/74), χ 2=4.471, P=0.035], smoking history [85.7% (30/35) vs. 63.5% (47/74), χ 2=5.647, P=0.018], lower body mass index [(25.8±3.1) kg/m 2vs. (27.4±3.2) kg/m 2, t=2.461, P=0.033]. Compared with control group, the observation group had lower coronary Gensini score[(35.4±5.7) vs. (38.7±6.5), t=2.571, P=0.011], less number of stent[ (1.4±0.4) vs. (1.6±0.4), t=2.427, P=0.016]. And the lesions were mostly distributed in the right coronary artery in observation group (61.9%, 26/35) (χ 2=11.759, P=0.003). Conclusion:The improvement of sleep quality by PCI depends on the clinical features and coronary artery lesions of CHD patients with OSA.

RESUMEN
Objective To evaluate the efficacy and safety of combined use of ticagrelor and cilostazol for patients with acute coronary syndrome (ACS) complicated with upper digestive tract diseases following percutaneous coronary intervention ( PCI).Methods A total of 262 consecutive ACS patients complicated with upper digestive tract diseases followed-up for one-year after PCI were included in this study.The patients were allocated into control group (combined use of ticagrelor and aspirin , n＝184) and cilostazol group ( combined use of ticagrelor and cilostazol , n ＝78) for antiplatelet treatment.The basic characteristics of the patients , change of the treatment regimens , cardiovascular events and hemorrhagic events were compared between two groups .Results After one year of follow-up, 16.8%(31/184)patients in control group and 3.8%(3/78)in cilostazol group changed antiplatelet regimens (χ2＝8.200,P＝0.004).There was no statistical difference in use of statins and ACEI/ARB between two groups(P＞0.05).The rate of proton pump inhibitor use in control group was significantly higher than that in cilostazol group [82.1%(151/184) vs.52.6%(41/78), χ2＝24.35, P＝0.000].However, the dosage of β-blockers in cilostazol group was significantly higher than that in control group [(39.1 ±12.4) mg vs.(28.6 ±10.1) mg, t ＝7.174,P＝0.000].No statistical difference was found in total cardiovascular events between two groups [21.7%(40/184) vs.12.8%(10/78),χ2＝2.822,P＝0.121].The incidence of gastrointestinal hemorrhage in control group was significantly increased compared with cilostazol group [12.0%(22/184) vs.2.6%(2/78),χ2＝5.807,P ＝0.018], however, there was no significant difference in hemorrhagic events concerning the thrombolysis for myocardial infarction between two groups [17.4%(32/184) vs.9.0%(7/78), χ2＝3.063,P＝0.089].Conclusion Combined use of cilostazol and ticagrelor is effective and safe for ACS patients with gastrointestinal hemorrhage or a higher risk of hemorrhage .
RESUMEN
AIM:To explore the effects of endothelial indoleamine 2,3-dioxygenase (IDO) on the migration and the expression of contractile proteins in the pericytes.METHODS: Human pulmonary artery endothelial cells ( HPAECs) and rat cerebral microvascular pericytes were cultured in vitro.Over-expression of IDO in the HPAECs ( IDO-HPAECs) was established.The pericytes were treated with HPAEC-conditioned medium (control group), IDO-HPAEC conditioned medium (treatment group), or IDO-HPAECs-conditioned medium containing 1-methyl-DL-tryptophan (1-mT) ( inhibition group) .The concentrations of nitric oxide ( NO) , tryptophan and kynurenine in the co-culture system were de-termined.The viability, migration and the expression of the contractile proteins in the pericytes were compared.RE-SULTS:No statistical difference of the pericyte viability after treatment with IDO-HPAEC-conditioned medium at 6~48 h was observed (P>0.05).The migratory ability of the pericytes significantly decreased in treatment group compared with control group (P0.05).The concentration of tryptophan was significantly lower in treatment group than that in control group (P<0.01), and significantly higher in in-hibition group than that in treatment group (P<0.01).The concentration of kynurenine was significantly higher in treat-ment group than that in control group (P<0.01), and significantly lower in inhibition group than that in treatment group (P<0.01).The expression ofα-smooth muscle actin and desmin was significantly lower in treatment group than that in control group (P<0.01), and significantly higher in inhibition group than that in treatment group (P<0.01).CON-CLUSION:Endothelial IDO inhibits the migration and the expression of the contractile proteins in the pericytes, and may play essential roles in the regulation of microvasculatures.
RESUMEN
Objective To evaluate the diagnostic value of cardiac magnetic resonance (CMR) in suspected coronary heart disease patients with electrocardiogram abnormalities but normal coronary angiography. Methods The data of 25 suspected coronary heart disease patients with electrocardiogram abnormalities but normal coronary angiography were collected from Taiyuan central hospital between October 2010 and April 2012. Comparison was done in terms of anterior interventricular septal thickness, left ventricular posterior wall thickness, left ventricular end diastolic dimension, left ventricular end systolic dimension, left atrial diameterand ejection fraction measured by CMR and by UCG. Correlation of the aboved paremeters between the 2 imaging exams. Results 40%of patients had their diagnosis changed after CMR exam, 32%of the patients with adjusted assessment. The differences in anterior interventricular septal thickness, left ventricular posterior wall thickness, left ventricular enddiastolic dimension, left ventricular end systolic dimension, left atrial diameter, ejection fraction by CMR and by UCG were similar (P>0.05) with positive correlation (P<0.01). Conclusions CMR can provide diagnosis and evaluation information to chest pain patients with ECG abnormalities but normal CAG, and it is a good supplement for routine examination.
RESUMEN
Objective To evaluate the effect of propofol on interleukin-1β (IL-1β)-induced increase in monolayer permeability of human umbilical vein endothelial cells (HUVECs).Methods Primary HUVECs were cultured and purified by immuno-magnetic separation.The expression of VE-cadherin in endothelial cells was determined by immunofluorescence.The HUVEC monolayer permeability was detected by the Transwell system.The cells were seeded on the upper chamber (2 × 105 cells/well) and cultured for 3 days after confluence.The cells were treated in two ways.The cells were randomly divided into 6 groups (n =36 each) and 5 of the 6 groups treated with 1,2,5,10 and 20 ng/ml IL-1β for 24 h except for control group.The cells were also randomly divided into 5 groups (n =30 each) and 4 of the 5 groups were pretreated with 0,10,50 and 100 μmol/L propofol for 30 min,and then treated with 10 ng/ml IL-1β for 24 h except for control group.The cells were radomly divided into 3 groups (n =18 each) and 2 of the 3 groups were pretreated with 50 μmol/L propofol for 30 min,and then treated with 10 ng/ml IL-1β for 24 h or 30 min.The expression of occludin protien,p38 mitogen activiated protienkinase (p38 MAPK) and phosphorylated p38 MAPK (p-p38 MAPK) was determined by Western blot.Results Compared with control group,5,10 and 20 ng/ml IL-1β significantly increased HUVEC monolayer permeability in a concentration-dependent manner (P ＜ 0.05 or 0.01).10,50 and 100 μmol/L propofol inhibited IL-1 β-induced increase in the permeability of HUVEC monolayer permeability in a concentration-dependent manner (P ＜ 0.01).IL-1β could down-regulate HUVEC occludin protein expression,and activate p38MAPK signaling pathway,and propofol inhibited IL-1β-induced down-regulation of HUVEC occludin protein expression and activation of p38 MAPK signaling pathway (P ＜ 0.01).Conclusion Propofol can alleviate IL-1β-induced increase in the permeability of HUVEC monolayer via inhibiting activation of p38 MAPK signaling pathway.
