Background Proton pump inhibitors(PPIs) are recommended by the latest guidelines to reduce the risk of bleeding in acute myocardial infarction(AMI) patients treated with dual antiplatelet therapy(DAPT). However, previous pharmacodynamic and clinical studies have reported controversial results on the interaction between PPI and the P2 Y12 inhibitor clopidogrel. We investigated the impact of PPIs use on in-hospital outcomes in AMI patients, aiming to provide a new insight on the value of PPIs. Methods A total of 23,380 consecutive AMI patients who received clopidogrel with or without PPIs in the China Acute Myocardial Infarction(CAMI) registry were analyzed. The primary endpoint was major adverse cardiovascular and cerebrovascular events(MACCE) defined as a composite of in-hospital cardiac death, re-infarction and stroke. Propensity score matching(PSM) was used to control potential baseline confounders. Multivariate logistic regression analysis was performed to evaluate the effect of PPIs use on MACCE and gastrointestinal bleeding(GIB). Results Among the whole AMI population, a large majority received DAPT and 67.5% were co-medicated with PPIs. PPIs use was associated with a decreased risk of MACCE(Before PSM OR: 0.857, 95% CI: 0.742-0.990, P = 0.0359;after PSM OR: 0.862, 95% CI: 0.768-0.949, P = 0.0245) after multivariate adjustment. Patients receiving PPIs also had a lower risk of cardiac death but a higher risk of complicating with stroke. When GIB occurred, an alleviating trend of GIB severity was observed in PPIs group. Conclusions Our study is the first nation-wide large-scale study to show evidence on PPIs use in AMI patients treated with DAPT. We found that PPIs in combination with clopidogrel was associated with decreased risk for MACCE in AMI patients, and it might have a trend to mitigate GIB severity. Therefore, PPIs could become an available choice for AMI patients during hospitalization.

Photosynthesis and chlorophyll a fluorescence parameters, photochemical efficiency of PS II （Fv/Fm）, photochemical quenching of PS II （qP）, nonphotochemical quenching of PS II （NPQ）, maximum activity of PS II （Fv/Fo） as well as electron transport rate （ETR）, and quantum yield of PS II （ФPS II） were measured on flag leaves of the winter wheat treated by methanol at different concentrations. The results revealed that photosynthesis was greatly improved by methanol, as indicated by higher photosynthetic rates and stomatal conductance. The enhancement effect of methanol on photosynthesis was maintained for 3-4 days. Different methanol concentration treatments also increased intercellular CO2 concentration and transpiration rates. No significant decline was found in Fv/Fm, Fv/Fo, and ФPS II, which revealed no photoinhibition during methanol application in different methanol concentrations. Methanol showing no apparent inhibitory effects indicated higher potential photosynthetic capacity of flag leaves of winter wheat. However, the increase in photosynthesis was not followed by an increase in the photosynthetic activity （Fv/Fm）, and fluorescence parameters did not indicate an improvement in intercellular CO2 concentration and PS II photochemical efficiency compared with the control, thereby encouraging us to propose that lower leaf temperatures caused by applied methanol would reduce both dark respiration and photorespiration （most importantly）, thus, increasing net CO2 uptake and photosynthetic rates.

Objective To investigate the relevant factors of coronary artery disease （CAD） in young people under 40 years of age. Methods The study population was 292 young patients accepting coronary angiography in Fuwai Hospital from July to December 2006, including 272 men and 20 women, with the mean age being 36.7±3.7 years. The diagnosis of CAD was made in the cases presenting ~ 50% stenosis in coronary lumen in coronary angiography. Based on the diagnosis, 217 patients （204 men, 13 women） were assigned to CAD group, and 75 （68 men, 7 women） to non-CAD group. Clinical data and metabolic characteristics of the patients were collected and analyzed using t-test, Z2 test, and multinomial logistic regression with SPSS 8.0 software. Results Most study subjects were current smokers （209/292, 71.6%）, and more than half had body mass index （BMI）〉24 kg/m2 （230/292, 78.8%） and usually took high-fat diet （162/292, 55.5%）. The proportion of heavy smokers （smoking history ≥10 years and t〉20 cigarettes per clay） were significantly higher in the CAD group than in the non-CAD group [20.7% （45/217） vs. 9.3% （7/75）, P=0.015）]. Heavy smoking [odds ratio （OR）, 1.89; 95% confidence interval （CI）, 1.74-2.05], hypertension （OR, 1.56; 95% CI, 1.48-1.65）, alcohol （OR, 1.37; 95% CI, 1.30-1.46）, type 2 diabetes mellitus （OR, 1.37; 95% CI, 1.25-1.50）, high-fat diet （OR, 1.35; 95% CI, 1.28-1.43）, and BMI〉24 kg/m2 （OR, 1.09; 95% CI, 1.03-1.17） were factors related to CAD in the young patients （all P〈0.05）. Total cholesterol （4.56_±1.46 mmol/L vs. 4.09_±1.00 mmol/L）, low-density lipoprotein cholesterol （2.38±1.11 mmol/L vs. 2.14±0.63 rnmol/L）, lipoprotein a （134.97±109.70 mg/L vs. 101.58±58.39 mg/L）, uric acid （359.89_±100.09 μmol/L vs. 336.75±94.36 μmol/L）, erythrocyte sedimentation rate （9.98± 12.19 ram/hour vs. 4.89_±4.92 mm/hour）, high-sensitivity C-reactive protein （3.42±4.39 mg/L vs. 2.80±_3.77 mg/L） and Big endothelin-1 （1.41±1.50 fmol/mL vs. 0.77_±1.13 fmol/mL） in plasma were significantly incr

Objectives To evaluate the very long-term safety and effectiveness of drug-eluting stents （DES） compared to bare-metal stents （BMS） for patients with large coronary vessels. Methods From April 2004 to October 2006, 2407 consecutive patients undergoing de novo lesion percutaneous coronary intervention with reference vessel diameter greater than or equal to 3.5 mm at Fu Wai Hospital in Beijing, China, were prospectively enrolled into this study. We obtained 9-year clinical outcomes including death, myocardial infarction （MI）, thrombosis, target lesion revascularization （TLR）, target vessel revascularization （TVR）, and major adverse cardiac events （MACE, the composite of death, MI, and TVR）. We performed Cox＇s proportional-hazards models to assess relative risks of all the outcome measures after propensity match. Results After propensity scoring, 514 DES-treated patients were matched to 514 BMS-treated patients. The patients treated with BMS were associated with higher risk ofTLR （HR： 2.55, 95%CI： 1.520-4.277, P = 0.0004） and TVR （HR： 1.889, 95%CI： 1.185-3.011, P = 0.0075）, but the rates of death/MI and MACE were not statistically different. All Academic Research Consortium definition stent thrombosis at 9-year were comparable in the two groups. Conclusions During long-term follow-up through nine years, use of DES in patients with large coronary arteries was still associated with significant reductions in the risks of TLR and TVR.
