RÉSUMÉ
Objective:To investigate the possible mechanism of rubbing abdomen to regulate intestinal homeostasis in irritable bowel syndrome with constipation (IBS-C) mouse models.Methods:IBS-C mouse models of intestinal immune dysfunction were established using trinitrobenzene sulfonic acid (TNBS)-induced C57BL/J6 male mice. Thirty C57BL/J6 mice were randomly divided into three groups: the control group, the model group, and the mogul group. After 7 days of modeling, mice in the mogul group were given a mogul mechanical stimulation intervention once per day for 2 weeks, while mice in the control and model groups were not given any intervention. Changes in serum levels of interleukin-6 (IL-6) and IL-17A were detected by enzyme-linked immune sorbent assay (ELISA) and immunohistochemistry. The gene expression and protein levels of IL-17A and IL-23 were detected by quantitative real-time fluorescence PCR (qRT-PCR) and Western Blot, respectively. The morphological changes were observed by HE staining. The CD44 and CD62L expression changes were observed by immunofluorescence staining.Results:Compared with the model group, the levels of IL-6 and IL-17A in the serum of mice in the mogul group were decreased, and the expression of IL-6 and IL-7A in the tissues was down-regulated (all P<0.001). In addition, the gene expression and protein expression levels of IL-17A and IL-13 in the tissues of mice in the mogul group were decreased (all P<0.001). HE staining results showed that the mogul mechanical stimulation intervention could repair colonic tissues and reduce the inflammatory response. Immunofluorescence staining results showed that mogul mechanical stimulation intervention could downregulate the expression of CD44 but had no modulating effect on the expression of CD62L. Conclusions:Rubbing abdomen can improve intestinal homeostasis in IBS-C model mice by regulating changes in Th17 cell function.
RÉSUMÉ
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.
