Objective To evaluate the effects of Pidomorph on serum immune cell level and T cell subsets in children with bronchial asthma.Methods 140 pediatric patients with bronchial asthma from January 2014 to October 2016 in our hospital were randomly divided into experimental group and control group according to the order of admission,70 cases in each groups.The control group was treated with conventional glucocorticoid drugs,and the experimental group was treated with pidotimod.The total effective rate of clinical treatment,the rate of rapid breathing in the flow rate,forced expiratory peak value,forced breathing vital capacity were compared between two groups three weeks after treatment,and the serum levels of immune cells(IgA,IgG,IgM)and T cell subsets(CD3+,CD4+,CD8+)were compared before and after treatment.Results The total effective rate was 92.86％(65/70)in the experimental group and 72.86％(51/70)in the control group,the total effective rate in the experimental group was significantly higher than that in the control group(P<0.05); Forced breathing speed in the speed,forced expiratory peak value,forced breathing vital capacity in the experimental group were better than the control group(P<0.05); After treatment,the levels of serum immune cells(IgA,IgG,IgM)in the experimental group were significantly higher than those in the control group(P<0.05); After treatment,the levels of T cell subsets(CD3+,CD4+,CD8+)in the experimental group were significantly higher than those in the control group(P<0.05).Conclusion Pidotimod is effective and safe in the treatment of bronchial asthma in children,it can effectively regulate T cell subsets and improve the immune function of children with asthma.

Objective To explore the clinical manifestations,imaging findings,pathological classification and treatment of congenital cystic adenomatoid malformation (CCAM)of the lung.Methods The clinical features,imaging findings,pathology information,diagnosis,treatment method and its prognosis of children with CCAMconfirmed by ope-ration and pathology were retrospectively analyzed in Yuying Children′s Hospital Affiliated to Wenzhou Medical Univer-sity from August 2006 to August 201 4.Results Eleven patients were boys and 4 patients were girls.One case had a-symptomatic clinical features,1 2 cases had pulmonary infection,1 case had recurrent chest pain,and 1 case had de-pressed deformity in sternum inferior segment.Chest CT scanning indicated that 9 cases had multiple gas cysts at unila-teral side of lung,among which 1 case was of funnel chest and pulmonary sequestration,1 case of huge cyst containing air and fluid at inferior lobe of left lung,and 4 cases of high density lung shadow;CT examination indicated that 1 case had recurrent chest pain and eventration of diaphragm of the right side combined with pulmonary sequestration.All ca-ses were treated by surgical resection,of whom 1 case was given cystectomy and sequestrectomy,diaphragmatic plication respectively,1 case complicated with funnel chest disease underwent lesion pulmonary lobectomy,sequestrectomy and minimally invasive corrective surgery in pectus excavatum (Nuss surgery),and the remaining 1 2 cases received lesion pulmonary lobectomy.All of 1 5 cases recovered well without complications.Pathological classification type of CCAMin-cluded 1 1 cases of type Ⅰ,3 cases of type Ⅱ and 1 case of type Ⅲ,among which 2 cases had pulmonary sequestration. Conclusions CCAMis a rare disease which can be discovered along with pulmonary infection.Multiple gas cysts are the most common imaging findings and the preoperative diagnosis of CCAM is mostly based on chest CT examination. Type Ⅰ and type Ⅱ are the most common pathological classification.The surgical resection should be given early surgi-cal resection and the prognosis is usually good.
