ABSTRACT
Objective To investigate the effects of glucocorticoid combined with spleen aminopeptide on immune function and pulmonary function in children with combined allergic rhinitis and asthma syndrome (CARAS).Methods A total of 166 cases of CARAS were divided into observation group (84 cases) and control group (82 cases),the patients in the control group were treated by nasal inhalation of Budesonide Aerosol,in addition to the treatment of control group the observation group was given spleen aminopeptide oral lyophilized powder for treatment,and two groups were treated continuously for 3 months.The effect of 2 groups of children,and the changes of immune and lung function before and after treatment were compared.Results Rhinitis and asthma were significantly reduced in two groups of children after treatment,and the reductions of the score of rhinitis symptoms and the asthma score in the observation group were more significant than those in the control group(P＜0.05).The humoral immunity index (IgG,IgM and IgA) of the 2 groups increased significantly after treatment.CD3+,CD4+ and the ratio of CD4+/CD8+ in the cellular immune indexes increased significantly,and CD8+ decreased significantly.The immune indexes in the observation group were significantly improved compared with those in the control group (P＜0.05).After treatment,the forced expiratory volume in one second(FEV1) and maximal expiratory flow rate (PEFR) of the 2 groups increased significantly compared with those before treatment,and the degree of increase in the observation group was significantly higher than that in the control group(P＜0.01).Conclusion Glucocorticoid combined with spleen aminopeptide could not only improve the symptoms and signs of children with CARAS,but also significantly enhance cellular immunity,humoral immunity and pulmonary function.
ABSTRACT
Objective The incidence of laryngeal cancer has characteristic of regional differences, but the etiology is not clear. The aim of this study was to analyze the correlation between RECK gene promoter methylation and prognosis of laryngeal squamous cell carci-noma patients through detecting the RECK gene methylation status of primary laryngeal squamous cell carcinoma and adjacent tissues . Methods Methylation specific PCR assay was used to detect the RECK gene promoter methylation status of 70 laryngeal squamous cell carci-noma specimens in our hospital from July 2006 to Dcember 2007, and the differences of methylation status with different pathological parame-ters were compared.The correlation between RECK gene promoter methylation and prognosis of 64 patients completed five-year follow-up was analyzed. Results The RECK gene methylation rate (86.67%) of patients with poor differentiation in tumor cells was much higher than that of the patients with a moderate and better tumor cell differentiation (43.64%) (P<0.05).In 29 pairs of laryngeal cancer-adjacent tis-sues specimens matches, the RECK gene methylation in laryngeal carcinoma (55.12%) was higher than normal tissues (27.59%) ( P=0.029).RECK gene methylation significantly shortened the tumor free survival and overall survival analyzed by Log-rank (P=0.024, P=0.017).Lymph node metastasis and clinical stage in classⅢ-Ⅳsignificantly shortened the tumor free survival and overall survival (P=0.029, P=0.024;P=0.033, P=0.032).Moderate and better tumor cell differentiation significantly shortened the tumor free survival (P=0.024, P=0.049).Lymph node metastasis, clinical stage, and RECK gene methylation were independent risk factors of overall survival. Conclusion RECK gene promoter methylation in human laryngeal squamous cell carcinoma is an early event and may occur in the adjacent normal tissues, predicting a poor prognosis in patients.
