Objective To observe the clinical efficacy of pediatric massage(tuina)for chronic cough in children.Methods A total of 96 cases were randomized into a control group and an observation group,with 48 cases in each group.Cases in the control group received routine pediatric massage manipulations.Cases in the observation group received additional Mo-rubbing abdomen manipulation.The treatment was done 3 times a week and 12 times made up a treatment session.The cough symptom scores were evaluated before treatment and after 3,6,9 and 12 treatments respectively.Results There were 8 dropouts in the observation group and 5 dropouts in the control group.Before treatment,there was no statistical difference in coughing score between the two groups(P>0.05).After 9 times of treatment,the total coughing scores were significantly reduced in both groups(both P<0.05);however,there were no statistical differences between the two groups in the score differences between before treatment and after 3,6 and 9 times of treatment(all P>0.05).After 12 times of treatment,the total coughing scores were significantly reduced in both groups(both P<0.05),along with a statistical difference between the two groups in the score difference between before treatment and after 12 times of treatment(P<0.05).There was a statistical difference between the two groups in overall response(P<0.05).The total effective rate in the observation group was 92.5%,versus 86.0%in the control group,showing a statistical difference(P<0.05).Conclusion The routine pediatric massage manipulations alone or in combination with Mo-rubbing abdomen manipulation both can significantly improve chronic cough in children;however,the combination obtains a better effect. 展开更多

Objective: To observe the clinical efficacy of acupoint injection of Chuankezhi plus acupoint sticking treatment for bronchial asthma, and provide clinical evidence for the synergy of the two therapies, and explore their synergistic mechanism. Methods: A total of 70 patients were randomized into an acupoint injection plus sticking group and an acupiont sticking group by the random number table, with 35 cases in each group. The treatment took place in July and August. The acupoint injection plus sticking group was treated with acupoint injection and acupiont sticking, while the acupiont sticking group was treated only with acupiont sticking therapy. The treatment course was 4 weeks. After the treatment, the scores of symptom scale in the two groups before treatment, 3 months and 6 months after the treatment were observed. Results: During the treatment, there were 5 dropouts in the acupoint injection plus sticking group with 30 cases remained, and 4 dropouts in the acupiont sticking group with 31 cases remained. Before the treatment, there was no significant difference in the total scores of symptom scale between the two groups. Three months after the treatment, the total scores of symptom scale of both groups were lower than those before treatment, and the intra-group differences were statistically significant (bothP<0.05). In the inter-group comparison, there was no significant difference in the difference values of the scores before treatment and 3 months after treatment (P>0.05). Six months after the treatment, the total scores of symptom scale in both groups were lower than those before treatment, and the intra-group differences were statistically significant (bothP<0.05), so were the differences in the difference values of the scores before treatment and 6 months after treatment (bothP<0.05). Conclusion: Acupoint injection of Chuankezhi plus acupoint sticking or acupoint sticking alone both can improve the symptoms of patients with bronchial asthma. Acupoint injection of Chuankezhi plus acupoint sticking has a higher total effective rate than single acupoint sticking therapy. 展开更多
