Methods: It was a prospective, observational study, conducted in Intensive Care Unit of Mianyang Central Hospital , from August 2017 to August 2018. A total of 37 cases of newly diagnosed cases of sepsis were included in the study and 20 healthy adults were taken as controls. According to the mortality within 30 d,patients with sepsis were divided into survival group (n=15) and death group (n=22) . The white blood cell (WBC), neutrophils count (NEU), lymphocyte count (LYM), and NLR in peripheral blood were recorded at 1, 3,5,7 days after admission for patients . Logistic regression analysis was used to evaluate the risk factors for predicting the outcome, and receiver-operating characteristic curve (ROC) was plotted for evaluating the value of these factors on the 30-day prognosis. Results: NLR on day 1 (NLR1) of sepsis was signifcantly higher as compared to controls (P<0.001), with far higher diagnostic efficiency (AUC=0.959) than WBC (AUC=0.788) and equivalent to NEU% (AUC=0.942);WBC and NLR on day 7 (NLR7) is independent risk factors for 30-day mortality of sepsis patients and is helpful to predict the prognosis of sepsis. Conclusion: NLR can be a convenient and useful diagnostic and prognostic marker in sepsis and is of great clinical applicative value for primary hospitals without ability to detect other costly biomarkers and for emergency department.展开更多

The neutrophil-to-lymphocyte ratio (NLR) is a novel,feasible marker representing an integrated response to inflammation. The purpose of the current review is to evaluate all available evidence from clinical observational trials about the relationships between NLR and ischemic stroke. Methods: We searched PubMed,Embase,and CNKI for clinical observational trials on NLR published up to August 1,2018,and made a brief summary about the predictive value of the correlation between NLR and ischemic stroke. Results: A high NLR is associated with increased risk of developing stroke and is a new addition to the traditional risk factors of atrial fibrillation and carotid artery stenosis. NLR on admission is an independent predictor of short- and long-term mortality in patients with acute ischemic stroke. In patients receiving recombinant tissue plasminogen activator or endovascular treatments,high NLR was reported with higher mortality or major disability. Conclusion: NLR provides an easy,useful method to predict the incidence,severity,and prognosis of ischemic stroke;thus,it can emerge as a new potential target for anti-inflammatory treatment and development of therapeutic strategies.展开更多

According to the characteristic of endometriosis, we analyzed the new biomarker neutrophil-to-lymphocyte ratio （NLR） and the combination of NLR and serum CA-125 to investigate their diagnostic value for identifying stages III and IV endometdosis. Methods The values of serum CA-125 and routine blood tests were collected from 197 patients with endometriosis, 102 with benign tumors and 112 healthy individuals. We investigated the sensitivity and specificity of NLR and its combination with serum-CA-125 for diagnosing stages III and IV endometriosis by using receiver operating characteristic （ROC）. Results The mean values of NLR, the combination of serum CA-125 and NLR （combination） of the groups with stages III and IV endometriosis were significantly higher than the other two groups. Serum CA-125, NLR, and the combined biomarkers could significantly discriminate the stages Ill and IV endometriosis group from the other two groups （P〈0.05）. NLR shows a lower sensitivity of 57.9% and specificity of 65.2% with a cutoff value at 1.82. And the combination of biomarkers has the highest AUC of 0.949 with a sensitivity of 86.8% and specificity of 92.0% at the cutoff value of 44.40. In addition, for patients with negative CA-125, 55.36% and 53.57% of the patients were able to be diagnosed with endometriosis by using NLR alone and the combination of biomarkers. Conclusion For diagnosing stages III and IV endometriosis, the neutrophil-to-lymphocyte ratio is a better adjuvant to serum CA-125, and the neutrophil-to-lymphocyte ratio is valuable in diagnosing stages III and IV endometriosis for patients with negative serum CA-125.展开更多
