RESUMO

Background: Our study aimed to investigate the incidence of depression in 387 patients with asthma. Methods: The Zung self-rating depression scale and the Hamilton depression scale were used to evaluate the depression status in patients with asthma. Results: Results of logistic regression analysis indicated that, severity of asthma symptoms, taking medicine, frequency of asthma onset, and lack of education were the major risk factors for depression in patients with asthma. Conclusion: Depression is a complication with high morbidity in patients with asthma. It largely affects disease control of asthma and the quality life in patients. Multiple factors are relevant for depression in the patient with asthma. This study provided a comprehensive horizon for clinical management and treatment of depression in patients with asthma.

RESUMO

Eosinophils exert a number of inflammatory effects through the degranulation and release of intracellular mediators, and are considered to be key effector cells in allergic disorders, including asthma. In order to investigate the regulatory effects of the natural polyphenol, resveratrol, on eosinophils derived from asthmatic individuals, the cell counting Kit­8 assay and flow cytometry analysis were used to determine cell proliferation and cell cycle progression in these cells, respectively. Cellular apoptosis was detected using annexin V-fluorescein isothiocyanate/propidium iodide double­staining. The protein expression levels of p53, p21, cyclin­dependent kinase 2 (CDK2), cyclin A, cyclin E, Bim, B­cell lymphoma (Bcl)­2 and Bcl­2­associated X protein (Bax) were measured by western blot analysis following resveratrol treatment. The results indicated that resveratrol effectively suppressed the proliferation of eosinophils from asthmatic patients in a concentration­ and time­dependent manner. In addition, resveratrol was observed to arrest cell cycle progression in G1/S phase by increasing the protein expression levels of p53 and p21, and concurrently reducing the protein expression levels of CDK2, cyclin A and cyclin E. Furthermore, resveratrol treatment significantly induced apoptosis in eosinophils, likely through the upregulation of Bim and Bax protein expression levels and the downregulation of Bcl­2 protein expression. These findings suggested that resveratrol may be a potential agent for the treatment of asthma by decreasing the number of eosinophils.

RESUMO

OBJECTIVE: To explore the relationship between disintegrin and metalloproteinase (ADAM33) gene polymorphism of bronchial asthma and its severity in Xinjiang Uygur population. METHODS: From January to December 2009, a total of 126 consecutive Uighur asthmatics with a definite diagnosis at First Affiliated Hospital of Xinjiang Medical University were assigned into intermittent mild (n = 62), moderate (n = 39) and severe (n = 25) groups according to the severity of illness. The control group was a 1: 1 paired population from healthy subjects matched similarly with regards to gender, race, residence and age (with a difference <5 years). The ADAM33 gene polymorphisms of F+1, S+1, T1, T2 and V4 locus allele in each group were tested by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP). RESULTS: In ADAM33, the distribution of T1, T2 and V4 locus allele in asthmatics and controls had a significant difference (χ² = 8.064, P = 0.018; χ² = 8.013, P = 0.018 and χ² = 11.737, P = 0.003). The distribution of allelic frequency showed that all T1 (C), T2 (A) and V4 (G) locus allele increased the relative risk degree of asthmatics (OR = 2.080, 2.139 and 1.912). The distribution frequency of T1 (TC and TT), T2 (AG and GG), V4 (GG and CC) genotypes in mild, moderate and severe groups had significant differences (all P < 0.05).Linkage disequilibrium analysis showed that in asthmatics, the presence of Hap2 (CATGC) was much lower than controls (20.4% vs 30.4%; χ² = 6.597, P = 0.010) while Hap4 (CACAC) and Hap5 (TACAG) were much higher than those in controls (9.6% vs 4.8% and 6.8% vs 2.8%; χ² = 4.545, P = 0.033 and χ² = 4.377, P = 0.036). CONCLUSIONS: The ADAM33 gene polymorphism of T1, T2 and V4 locus allele may be associated with asthma and its severity in Xinjiang. And Uighur population may have both susceptible and protective haplotypes of asthmatics.
