Objective To determine the diagnostic value of ractional exhaled nitric oxide (FeNO) in eosinophils (EOS) bronchial asthma and its significance in appraising of therapeutic reaction of inhaled corticosteroids (ICS) for EOS bronchial asthma.Methods A total of sixty-two patients with bronchial asthma in the First Mfiliated Hospital of Xinxiang Medical University from April 2015 to February 2016 were selected as asthma group;at the same time,sixty-two healthy people were recruited as control group.The patients in asthma group were divided into EOS asthma group(n =31) and non EOS asthma group (n =31) according to the induced sputum cell count;the patients in EOS asthma group were divided into mild (n =7),moderate (n =13) and sever asthma group (n =1 1) according to the severity of the disease.The patients in asthma group were given conventional therapy(doxofylline 0.2 g intravenous infusion,two times per day;oral cetirizine 10 mg,one time per night;oral montelukast 10 mg,one time per night;budesonide 2 mg and compound ipratropium bromide solution 2.5 mL by aerosol rebreathing method,two times per day) for seven days.The pulmonary function,asthma control test(ACT) score,FeNO level and the ratio of EOS of patients were detected before and after treatment;the FeNO levels of person in the control group were tested.The FeNO levels of subjects were compared in each group;the correlation between FeNO level and EOS ratio was analysed in asthmatic group;the controlling rates of patients in asthmatic group were compared.Results Before treatment,the FeNO level in control group and asthma group was (9.57 ± 6.61),(30.23 ± 8.9 1) ppb respectively;the FeNO level in control group was significantly lower than that in asthma group (t =7.414,P ＜ 0.05).Before treatment,the FeNO level of patients in EOS asthma group and non EOS asthma group was (59.62 ± 29.04),(18.20 ± 11.33) ppb respectively;the FeNO level in non EOS asthma group was lower than that in EOS asthma group (t =6.568,P ＜ 0.05).In asthma group,the level of FeNO was positively correlated with EOS ratio(r =0.823,P ＜ 0.05).There was no statistic difference in FeNO level of patients in non EOS asthma group before and after treatment(t =2.013,P ＞ 0.05).The FeNO levels of patients in EOS asthma group after treatment were significantly lower than those before treatment (t =7.740,P ＜ 0.05);the FeNO levels of patients in mild,moderate and sever asthma group after treatment were significantly lower than those before treatment(t =3.535,8.171,7.161;P ＜0.05).The control rate of patients in EOS asthma group(67.7％,21/31) was significantly higher than that in the non EOS asthma group(22.6％,7/31) (x2 =12.765,P ＜0.05).The control rate of patients in mild,moderate and sever asthma group was 28.6％ (2/7),76.9 ％ (10/13) and 81.8 ％ (9/11) respectively;the control rate of patients in mild asthma group was significantly lower than that in moderate and sever asthma group (x2 =6.418,7.103;P ＜ 0.05);there was no statistic difference in control rate of patients between moderate asthma group and sever asthma group(x2 =7.103,P ＞ 0.05).Conclusion FeNO level can reflect the degree of airway inflammation,and can be used for the diagnosis of EOS phenotype asthma,and also has certain clinical value in evaluating the therapeutic reaction of ICS for treatment of EOS asthma.

Fascin expression in lung cancer and its clinical significance / 中国医师杂志

Objective To investigate Fascin expression in human lung cancer tissues and its clinical significance.Methods Immunohistochemistry was performed in 62 patients with different histological types and clinical stages of lung cancer and 92 cases with other malignant tumors.Fascin positive rate in each group was calculated and the differences of pathological characters between the two groups were analyzed.Results Fascin expression in lung cancer tissues was significantly higher than that in normal lung tissues(P ＜ 0.05),its expression varied by different clinical stage of lung cancer tissue differentiation.As differentiation degree decreased,Fascin positive rate increased.Fascin expression was independent with age,sex,smoking history(P ＞ 0.05).Fascin expression had no significant difference between lung cancer group and other tumor group(P ＞ 0.05).Conclusions Fascin expression raising might be common in malignant tumors.Fascin expression in lung tissues indicated the possibility of lung cancer.In lung tissue,high expression of Fasein was a sign of poor differentiation and malignant status of lung cancer.

Activation of nuclear factor kappaB of monocyte in patients with chronic obstructive pulmonary disease / 新乡医学院学报

Objective To investigate the role of NF-κB activation in the inflammatory mechanism of chronic obstructive pulmonary disease (COPD).Methods Monocyte were collected from patients with COPD and were cultured,and stimulated with lipopolysaccharide (LPS) ; NF-κB p65 activation was measured by immunohistochemistry; SOD ,MDA and IL-8 and lung function were determined synchronously.Results The NF-κB p65 was induced by LPS in monocyte in all subjects, but it was most markedly done in COPD patients with exacerbateions; There was positive correlation between the NF-κB p65 activation of monocytes and levels of IL-8 and MDA in circulation, but it was negative correlation to SOD.Conclusion NF-κB plays a vital role in regulating product of IL-8 in monocyte in COPD.

Research of Plasma Endothelin-1,Nitrousoxide,Blood Gas,and Blood Viscosity in Patients with Chronic Pulmonary Disease / 中国康复理论与实践

@#Objective To explore the changes of plasma endothelin-1 (ET-1), nitrousoxide (NO), blood gas analysis, and blood rheology in patients with chronic bronchitis (CB), pulmonary emphysema (PE) and pulmonary heart disease (PHD) at different periods.Methods The plasma ET-1, NO, blood viscosity, hematocrit (Hct) and aggregation index (AI) of patients in groups of CB, PE and PHD, and the subjects of the control group were tested and compared. Blood gas analysis of subjects in four groups also performed and compared. Each group had 40 cases.Results In PE and PHD patients, the ET-1 level was higher, the indexes of blood gas analysis and blood rheology were abnormal. When PE developed into PHD, the ET-1 and PaCO2 tended to increase, PaO2 tended to decrease. When CB developed into PE and PHD, the blood viscosity, pressure volume and AI tended to increase, but NO tended to decrease.Conclusion When CB developed into PE or PHD, ET-1, PaCO2 tend to increase and NO, pH, PaO2 tend to decrease; increased red blood cells, blood viscosity and AI become severe.
