ABSTRACT
Objective:To investigate the relationship between neutrophil to lymphocyte ratio (NLR) and contrast-induced nephropathy (CIN) in patients with percutaneous coronary intervention (PCI).Methods:A total of 176 patients received PCI in our hospital from 2015-05 to 2016-12 were enrolled.Blood levels of white blood cells (WBC),neutrophils (N),lymphocytes (L);serum creatinine (SCr),blood urea nitrogen (BUN),uric acid (UA),cystatin C (CysC) were examined within 24 h of admission and NLR was calculated.According to NLR,the patients were divided into 3 groups:Low NLR group,NLR＜1.60,n=58,Moderate NLR group,1.60≤NLR≤2.36,n=62 and High NLR group,NLR＞2.36,n=56.SCr and CysC were re-examined at 48 h and 72 h after PCI.Pearson analysis was conducted for correlation study and Logistic regression analysis was used to identify whether NLR was the risk factor for CIN occurrence.Results:Compared with baseline condition,SCr and CysC were increased in all 3 groups,all P＜0.05.Pearson analysis indicated that NLR was positively related to SCr and CysC elevation (r=0.785 and r=0.764),both P＜0.05;Logistic regression analysis presented that NLR was an independent risk factor for CIN occurrence.Conclusion:NLR was positively related to contrast induced kidney injury,it was the risk factor for CIN occurrence in PCI patients.
ABSTRACT
Allergic diseases can be induced by abundant airborne allergenic pollens with symptoms such as allergic rhinitis and bronchial asthma,which can seriously threaten human health.The species and distribution of airborne pollens differed in different regions,based on the difference of geographical environment and climate conditions.Therefore,the occurrence of pollinosis was of obviously regional and seasonal divergence.Inappropriate urban greening,tree species selection and environmental pollution have contributed to a dramatic increase in the number of pollen sensitizing plants and hay fever.The species and dispersal regularity of allergenic pollen plants in different administrative areas in China in recent 10 years are reviewed in present paper for providing scientific basis on controlling pollinosis and reasonable greening of urban environment.
