Objective::This study aimed to evaluate the major adverse cardiovascular and cerebrovascular events (MACCEs) and overall safety profile associated with iodixanol in Chinese patients undergoing percutaneous coronary intervention (PCI).Methods::Patients at 30 centers in China registered in the OpenClinic v3.6 database from October 30, 2013, to October 7, 2015, were included in the study. The primary endpoint was in-hospital MACCEs including target lesion revascularization (TLR), stroke, stent thrombosis, cardiac death, and PCI-related myocardial infarction (MI) within 72 h post-PCI. Secondary endpoints were MACCEs from 72 h to 30 d post-PCI and other safety events within 30 d post-PCI.Results::A total of 3,042 patients were enrolled. The incidence of MACCEs within 72 h post-PCI was 2.33% ( n = 71), including cardiac death (0.03%, n = 1) and PCI-related MI (2.30%, n = 70). The incidence of MACCEs from 72 h to 30 d post-PCI was 0.16% ( n = 5), including cardiac death (0.10%, n = 3), PCI-related MI (0.03%, n = 1), and TLR for stent thrombosis (0.03%, n = 1). The incidence of composite angiographic or procedural complications was 2.86% ( n = 87); 233 (7.86%) patients had results suggesting contrast-induced acute kidney injury. Conclusions::These findings indicate that the use of iodixanol in Chinese patients undergoing PCI is associated with a low incidence of MACCEs, confirming its safety in this population.

Objective: Previous cross-sectional studies suggested that elevated levels of total cholesterol content of erythrocyte membrane (CEM) could significantly increase the risk of acute coronary syndrome (ACS). The purpose of the present study was to assess the predictive value of baseline CEM levels for the risk of clinical endpoint events in patients with ACS through prospective follow-up studies. Methods: This study is a prospective follow-up study, which consisted of 859 patients with first ACS (698 patients with unstable angina pectoris and 161 patients with acute myocardial infarction), diagnosed and hospitalized in the First and Second Affiliated Hospital of Anhui Medical University. The routine blood lipid levels and CEM were measured. Patients were divided into two groups according to the median of baseline CEM: CEM≤131.56 μg/mg group (n=430) and CEM>131.56 μg/mg group (n=429). Patients were followed up at 6 months interval. The clinical endpoints were nonfatal myocardial infarction, nonfatal stroke, all-cause mortality, all-cause mortality, heart failure requiring hospitalization, and coronary artery revascularization. Kaplan-Meier curve analysis and Cox proportional hazard model were used to analyze the impact of elevated CEM on the occurrence of clinical end-point events. HR values and 95%CI of each variable were obtained. Cox regression analysis of all-cause mortality was performed according to whether patients had risk factors for coronary heart disease (hypertension, diabetes, smoking and elevated LDL-C) and whether they were treated with PCI. Results: The follow-up time was 1 640 (1 380, 2 189) days. Cox analysis after adjustment showed that an elevated baseline of CEM (>131.56 μg/mg) was associated with an increased risk of all-cause mortality (HR=1.690, 95%CI 1.041-2.742, P=0.034), but had no significant predictive effect on the other clinical endpoints. Subgroup analysis showed that elevated baseline CEM levels in ACS patients with LDL-C>1.8 mmol/L (HR=1.687, 95%CI 1.026-2.774, P=0.039), receiving in-hospital PCI (HR=2.365, 95%CI 1.054-5.307, P=0.037), or male (HR=1.794, 95%CI 1.010-3.186, P=0.046) were associated with an increased risk of all-cause mortality. Conclusion The results showed that elevated CEM levels can increase the risk of all-cause mortality in ACS patients.

The patients’ bronchoalveolar lavage fluid through the electronic bronchoscopy, mycobacterium tuberculosis (MTB) culture, brushings and biopsy pathology were analyzed.Results 65 cases, bronchoscope alveolar lavage lfuid smear positive acid-fast stain 14 cases (21.54%), BAL mycobacterium tuberculosis culture positive 20 cases (30.76%), a bronchoscope brush positive 24 cases (36.92%), 35 cases of bronchoscopy biopsy, according to the performance under the bronchoscope positive 21 cases (60.00%), bronchoscopy combined different methods conifrmed 43 cases (66.15%).Conclusions Bronchoscopy in AIDS with bacteria sputum negative pulmonary tuberculosis diagnosis, it has important application value.

Objective To investigate the diagnostic value of urine neutrophil gelatinase apolipoprotein (NGAL) and kidney injury molecule 1 (KIM-1) as markers of CIN,and the effectiveness of hydration therapy in the prevention of CIN.Methods One hundred and twenty patients were randomly divided into control group and treatment group.The patients of treatment group received hydration therapy through intravenous fluid infusion.Urine samples were taken for detecting the value of albumin (mAlb),NGAL,and KIM-1 before surgery (T0),after surgery 12 h (T1),24 h (T2),48 h (T3),72 h (T4) by ELISA assay.The levels of urinary mAlb,Scr,BUN and cystatin C were detected at the same time.Results (1) The urine NGAL/Cr and KIM-1/Cr significantly increased and were more than twice the baseline value at the time of 12 h after PCI in 87 of 120 cases of the participants.There are eight cases occurred CIN (6.67％) and one case occurred in hydration treatment group (1.7％),seven cases were in control group (11.7％).The difference was statistically significant.(2) There were no significant difference in BUN,Scr,mAlb/Cr,Cys-C and GFR between two gToUps (P ＞ 0.05).(3) NGAL/Cr,KIM-1/Cr were elevated at T1 in both groups (P ＜ 0.01).In hydration treatment group,levels of NGAL/Cr and KIM-1/Cr decreased substantially to the level of T0 at T4(P ＜ 0.01),while in the control group they didn't.(4) Area under the ROC curve (AUC) of NGAL/Cr and KIM-1/Cr 12 h after PCI were 0.931 [95％ CI (0.889,0.973)] and 0.811 [95％ CI(0.736,0.886)] respectively (all P＜0.05).Conclusions NGAL and KIM-1 are sensitive and specific indicators for predicting early renal injury induced by contrast medium and can be used for early diagnosis of CIN.Hydration therapy can prevent the contrast agent-induced renal damage.
