Sepsis is one of the leading causes of hospitalization and death in adult intensive care units.Clinical observations have found that when the patient′s condition progresses to sepsis, the cost of medical resources is also increased and the mortality rate is also significantly increased.Therefore, early diagnosis, disease assessment, and prognosis of sepsis patients are crucial.At present, there are many biomarkers or scoring standards in clinical practice because of their different defects, which limits the clinical application.In recent years, many researchers at home and abroad have found that neutrophil/lymphocyte ratio as a simple and effective index is related to the progression of patients with sepsis.This review summarizes the research progress of neutrophil/lymphocyte ratio in sepsis, aiming to guide clinicians to have a better understanding of the condition of patients with sepsis, to help clinicians improve the diagnosis and treatment plan in time, thereby reducing the mortality rate of patients with sepsis.to improve its prognosis.

Objective To explore the diagnostic values of the Wells score, the revised Geneva score, the Padua score and the D-dimer level for venous thrombus embolism (VTE) in hospitalized patients with chronic pulmonary diseases. Methods The clinical data of inpatients with chronic pulmonary diseases (n=135) at department of respiratory medicine in Beijing Tongren Hospital from January 2012 to December 2018 were analyzed retrospectively.The Wells score, revised Geneva score and Padua score were calculated to evaluate the diagnosis and risk stratification of VTE, and the patients were divided into VTE group (n=50) and non-VTE group (n=85) according to the imaging results, and the clinical data between the two groups were compared.The diagnostic value of the three scoring systems and D-dimer level were compared by the area under the receiver operating characteristic (ROC) curve, and the Youden Index was calculated for the cut-off point. Results The incidence of VTE in patients with chronic pulmonary diseases was 37.04%.The D-Dimer level in VTE group was higher than that in non-VTE group [M(QR): 2 335(6 670) μg/L vs 400(870) μg/L, P<0.001]. The area under curve(AUC)of the ROC in Wells score, revised Geneva score, Padua score and the D-dimer level was 0.681±0.049, 0.614±0.051, 0.795±0.042, 0.811±0.039, separately.The cut-off of Padua score was 3 points and Youden Index was 0.497.The cut-off of D-dimer level was 1 460 μg/L and Youden Index was 0.519.The AUC of Padua score combined with D-dimer (0.865±0.034) was higher than that of Padua (P=0.009) or D-dimer (P=0.087), separately. Conclusions The index of Padua score combined with plasma D-dimer has the highest value in the diagnosis of VTE in patients with chronic pulmonary diseases, which can provide reference for timely, reasonable and standardized selection of imaging diagnosis, and further to improve the diagnostic accuracy and optimize the allocation of medical resources.

Objective To investigate the relationships between white blood cell (WBC), neutrophils, lymphocytes, neutrophil to lymphocyte ratio, platelet to lymphocyte ratio and serum IL-6 levels with pulmonary artery obstruction index (PAOI) in pulmonary embolism (PE) patients before and after short term treatment. Methods A prospective study was conducted on the PE patients first-diagnosed by computed tomographic pulmonary angiography in 3 hospitals from June 2015 to February 2017.The WBC, neutrophils, platelets, lymphocytes, neutrophil to lymphocyte radio (NLR), platelet to lymphocyte radio and serum IL-6 levels were examined pre-treatment and post-treatment on the 14th day.The relationships of these biomarkers with PAOI were analyzed pre-treatment and post-treatment on the 14th day. Results A total of 47 PE patients were enrolled from 3 hospitals.The PAOI was positively correlated with WBC, neutrophils, NLR, IL-6 pre-treatment (all P<0.05). The PAOI was positively correlated with IL-6 post-treatment (r=0.498, P=0.000). The varied rate of PAOI pre-and post-treatment were negatively correlated with NLR pre-treatment (r=-0.352, P=0.015), positively correlated with lymphocytes pre-treatment (r=0.335, P=0.021). Conclusions The WBC, neutrophils, NLR and IL-6 levels have correlations with PAOI, especially the IL-6 has closer correlation with PAOI, which could predict the degree of pulmonary artery obstruction better.The lower NLR and higher lymphocytes, the more significant of the embolus dissolution effect, they all have a certain clinical significance in predicting the degree of pulmonary embolus dissolution.

Cancer and its treatment are well-recognized risk factors for venous thromboembolism (VTE). Cancer-associated venous thromboembolism (CAT) is associated with significant mortality and healthcare utilization.Pooled analysis demonstrated a decrease of VTE events in cancer patients receiving heparin-based primary prophylaxis, but an increase of bleeding events.This article reviews the latest literature on risk assessment for CAT, risk assessment for anticoagulant related bleeding, and prevention and treatment of CAT.Through a comprehensive analysis of literature, it has been found that these VTE risk assessment models have limited predictive value on CAT and need to be further investigated.And no anticoagulantrelated bleeding risk model has been validated in cancer patients.The primary preventions of CAT include mechanical prevention and drug therapy.Patients with high risk for CAT should receive appropriate primary prevention based on the patient′s clinical condition and preferences.The currently available anticoagulants for CAT include unfractionated heparin, low molecular weight heparin, fondaparin sodium, direct oral anticoagulant, vitamin K receptor antagonist.Patients with CAT should be aware of the advantages and disadvantages of each anticoagulant, and be appropriately treated according to the patient′s clinical condition and preferences.

Objective To study whether the different concentrations of hydrogen combined with natural killer (NK) cells can contribute to the inhibition of lung cancer cell growth. Methods NK cells were isolated and cultured from peripheral blood of patients with non-small cell lung cancer.NK cells were treated with 20%, 40%, 60% hydrogen at different concentrations.NK cell growth curve was measured by methyl thiazolyl tetrazolium assay, NK cell cycle was analyzed by flow cytometry, the secretion of inflammatory factors in NK cells was analyzed by enzyme linked immunosorbent assay, in order to assess the impact of hydrogen on the proliferation of NK cells.NK cells and A549 cells (lung cancer cells) were added to co-culture system with a ratio of 1∶1 treated with different concentrations of hydrogen at the level of 20%, 40%, and 60%.The clone-forming, migration, and invasion ability of A549 cells were analyzed to evaluate the killing ability of hydrogen combined with NK cells. Results All the concentrations of hydrogen at the level of 20%, 40%, and 60% had little impact on the proliferation of NK cells.In the clone-forming and migration ability of A549 cells, 60% of the hydrogen combined with NK cells exhibited a little effect on inhibition, whereas, 20% or 40% of the hydrogen had no such effect.Nevertheless, all concentrations of the hydrogen combined with NK cells exhibited no effect on the invasion ability of A549 cells. Conclusions The combination of 60% of the hydrogen and NK cells could inhibit clone-forming and migration ability, as well as tumor growth, which provides a framework for future studies involving combined treatment of 60% of the hydrogen and NK cells for lung cancer.
