RESUMO
Objective:To evaluate the clinical effect of Chinese medical chiropractic in treating children with cough variant asthma syndrome (CVA) of Lung-Spleen Qi Deficiency.Methods:From October 2017 to October 2018, 60 CVA children with syndrome of lung-spleen qi deficiency were enrolled from pediatric outpatient department of Maoming Hospital of Traditional Chinese Medicine Affiliated to Guangzhou University of Traditional Chinese Medicine, and they were randomly divided into the control group and observation group by random number table method, with 30 in each group. The control group was given montelukast sodium granules orally on the basis of conventional treatment, and the observation group was given chiropractic treatment on the basis of the control group. Both groups were treated for 6 weeks and followed up for 2 months. The TCM syndrome scores were performed before and after treatment, and the changes of serum IgA, IgG, IgM and IgE were detected by ELISA. The recurrence was observed and recorded during the follow-up period, and the clinical effect rate was evaluated.Results:The total effect rates of the observation group and the control group were 86.7% (26/30) and 56.7% (17/30), respectively, with significant differences between the two groups ( χ2=6.648, P=0.008). After treatment, the scores of cough, sputum volume, oppression in chest, tongue coating, concomitant symptoms and total scores in the observation group were significantly lower than those in the control group ( t values were 2.639, 2.628, 2.633, 2.627, 2.725, 2.642, respectively, all Ps<0.05). After treatment, the IgA [(2.31 ± 1.20) g/L vs. (1.55 ± 0.72) g/L, t=2.635], IgG [(11.16 ± 3.39) g/L vs. (8.18 ± 3.27) g/L, t=2.751], IgM [(1.72 ± 0.34) g/L vs. (1.27 ± 0.36) g/L, t=2.660] in the observation group were significantly higher than those in the control group ( P<0.05), while the IgE [(51.32 ± 32.62) g/L vs. (74.58 ± 40.77) g/L, t=2.619] in the observation group were significantly lower than those in the control group ( P<0.05). During the follow-up, the recurrence rate was 19.2% (5/26) in the observation group and 70.6% (12/17) in the control group, and the difference between the two groups was statistically significant ( χ2=4.675, P=0.029). Conclusion:Chinese medicine chiropractic can improve the clinical symptoms and serum immune factor levels of children with cough variant asthma syndrome of lung and spleen qi deficiency, reduce the recurrence rate, and improve the clinical efficacy.
RESUMO
Objective To explore the effect of sustained performance on EEG approximate entropy (ApEn).Methods Fifty participants were divided into two groups according to whether they had undergone sustained performance .One day af-ter the sustained-performance group finished executing their task , the resting EEG of nine electrodes ( F3, Fz, F4, C3, Cz, C4, P3, Pz and P4) was acquired in two grups separately , and the ApEn of each electrode was calculated as well . Results The ApEn of F3 and Fz showed an evident decrease as well as randomness of spontaneous brain electrode activity in frontal lobes , especially in the left one .Conclusion The drop of ApEn and the asymmetry of frontal lobes might reflect participants′state of fatigue during sustained performance .
