ABSTRACT
<p><b>OBJECTIVE</b>To observe the effects of micro-invasive embedding combined with montelukast sodium and simple montelukast sodium for children cough variant asthma (CVA).</p><p><b>METHODS</b>A total of 240 patients were randomly assigned into an observation group and a control group, 120 cases in each one. Considering of cases dropping, 101 patients in the observation group and 105 cases in the control group were included. Montelukast sodium chewable tablets were applied before sleep for 3 months in the control group, 5 mg a time, once a day. Based on the treatment as the control group, micro-invasive embedding was used for 3 months in the observation group, twice in the first month and once in the other two months. The acupoints were Feishu (BL 13), Danzhong (CV 17), Dingchuan (EX-B 1), and Zusanli (ST 36). Follow-up was conducted 9 months after treatment in the two groups. The cough score, serum immunoglobulin (IgE, IgG, IgA), platelet activating factor (PAF) were observed before and after treatment. The indices were compared before and after treatment and at follow-up, including pulmonary function indices[peak expiratory flow rate (PEF), forced expiratory volume at the 1st second (FEV1)], and small airway function indices[forced expiratory flow rate with remaining 25% vital capacity (MEF25%), forced expiratory flow rate with remaining 50% vital capacity (MEF50%), forced expiratory flow rate with remaining 75% vital capacity (MEF75%) and mid expiratory flow rate (MEF25%-75%)]. Also, the total effects were evaluated.</p><p><b>RESULTS</b>①The total effective rate in the observation group was 93.1% (94/101), which was better than 87.6% (92/105) in the control group (<0.05). The cough disappearance time of the cured children in the observation group was (10.38±2.64) d, and it was shorter than (10.72 ±2.60) d of those in the control group (<0.05). After treatment, the cough score apparently decreased compared with those before treatment in the two groups (both<0.05), with better result in the observation group (<0.05). At follow-up, the recurrence frequency of the observation group was (1.43±1.20), and it was less than (1.91±1.71) in the control group (<0.05). ②The levels of serum IgA and IgG after treatment in the two groups increased, and those of serum IgE and PAF decreased, compared with those before treatment. There was statistically significance except IgG in the control group before and after treatment (all<0.05), with better Results in the observation group after treatment (all<0.05). ③ Compared with those before treatment, all the pulmonary function indices were improved obviously after treatment and at follow-up in the two groups (all<0.05), without statistically significance between the two groups (both>0.05). ④ There was no statistically significance before and after treatment on small airway function indices in the two groups (all>0.05). The indices at follow-up increased compared with those before treatment in the two groups (all<0.05), with better Results in the observation group (all<0.05).</p><p><b>CONCLUSIONS</b>Micro-invasive embedding combined with montelukast sodium achieved de-finite effect for children CVA, which can improve the body's immune and microcirculation. The effect is better than that of simple montelukast sodium on improving small airway function, etc.</p>
ABSTRACT
Objective To investigate the clinical effect of montelukast sodium in the treatment of cough vari-ant asthma in children,to provide reference for clinical treatment.Methods 128 cases of children with cough variant asthma were randomly divided into observation group and control group of 64 cases.The control group with routine measures for the treatment of asthma in children for treatment,the observation group in the control group based on the treatment regimen,plus montelukast sodium chawing treatment.The changes of the two groups were compared after 12 weeks of treatment,the clinical efficacy and lung function indexes before and after treatment.Through 6 months of follow -up,the recurrence of the disease between the two groups after treatment.Results The effective rate in the observation group was 43.75%,the total effective rate was 93.75%,which were significantly higher than those of the control group (χ2 =4.53,P <0.05);the two groups after treatment of FEV1 ,FVC,FEV1 /FVC,PEF and PEF during the day at night were significantly higher than those before treatment (t =4.11,3.23,3.82,5.12,3.12,5.54,4.31, 4.98,6.22,4.45,all P <0.05);After treatment,the FEV1 [(3.08 ±0.43)L],FVC[(3.89 ±0.52)L],FEV1 /FVC [(75.95 ±6.51)%],PEF day[(3.24 ±0.91 )L/s],PEF for the night[(3.51 ±1.01 )L/s]of the observation group were significantly higher than those of the control group (t =3.67,3.10,3.43,2.92,3.01,all P <0.05);The recurrence rate of the observation group was 3.13%,which was significantly lower than that of the control group (χ2 =4.82,P <0.05).Conclusion The clinical efficacy of montelukast can significantly improve cough variant asthma in children,improve children's lung function,reduce the recurrence rate of cough variant asthma.
