Changes of GH-IGFs and its relationship with growth retardation in children with bronchial asthma

Abstract Objective To explore the relationship between Growth Hormone Insulin-like Growth Factors (GH-IGFs) and growth retardation in children with bronchial asthma. Methods 112 children with bronchial asthma and 50 healthy children were studied. Serum GH, IGF-1, and Insulin-like Growth Factor Binding Protein 3 (IGFBP3) were assessed by ELISA. GH-IGFs-related parameters were compared, and the correlation between the parameters and bronchial asthma severity was analyzed. The bronchial asthma group was divided into the growth retardation group and non-growth retardation group to analyze the diagnostic value of GH-IGFs in growth retardation and the relationship between GH-IGFs and growth retardation. Results GH, IGF-1, and IGFBP3 in the bronchial asthma group were lower. GH, IGF-1, and IGFBP3 levels were decreased with the severity of bronchial asthma. GH, IGF-1, and IGFBP3 in the growth retardation group were lower than those in the non-growth retardation group. The AUC of GH-IGFs combined detection was higher than that of GH and IGFBP3 alone detection. GH < 9.27 μg/L and IGF-1 < 179.53 mmoL/L were risk factors for growth retardation in patients with bronchial asthma. Conclusion GH-IGFs-related parameters have diagnostic value for growth retardation in children, and decreased levels of GH and IGF-1 are risk factors for growth retardation in children.

Respiratory virus infection and risk factors in children with bronchial asthma / 公共卫生与预防医学

Objective To understand the etiological characteristics and risk factors of respiratory virus infection in children with bronchial asthma, and to provide theoretical basis for the prevention and treatment of respiratory virus infection in children with bronchial asthma. Methods A total of 374 children with bronchial asthma who were treated in Jianyang People's Hospital from December 2018 to December 2020 were enrolled. Pharyngeal swabs were collected from the outpatient children on the day of treatment, and 2 mL of nasopharyngeal secretions were collected from the hospitalized children within 24 hours by negative pressure aspirator. Seven viral antigens including RSV, ADV, IVA, IVB, PIVI, PIV II, and PIV III were detected. According to whether the virus test results were positive or not, they were divided into the experimental group (n=191) and the control group (n=183). Logistic regression analysis was used to screen the risk factors of respiratory virus infection in children with bronchial asthma. Results Among the 374 samples, the virus positive rate was 51.07% (191/374), and the top 3 virus species in the positive samples were RSV, ADV, and PIV III, accounting for 41.36% (79/191), 30.36% (58/191), and 9.42% (18/191), respectively. In addition, IVA accounted for 5.24% (10/191), PIV II accounted for 5.24% (10/191), PIVI accounted for 3.66% (7/191), and IVB accounted for 1.57% (3 /191). The positive rates of virus were 47.96% (94/196) and 54.49% (97/178) in male and female children, respectively, with no significant difference (χ2=1.597，P>0.05). The positive rate of 1~3 years old children was significantly higher than that of >3 years old group (χ2=6.412，P3 times, intravenous glucocorticoid application and onset season were independent risk factors for respiratory virus infection in children with bronchial asthma (P<0.05). Conclusion The infection season of acute respiratory tract infection in children with asthma is mainly concentrated in autumn and winter, with RSV as the main viral pathogen. Targeted preventive measures should be given to children with bronchial asthma who have more than 3 asthma attacks and intravenous glucocorticoid application, which can reduce respiratory virus infection in children with asthma.

Acupoint thread-embedding as adjuvant therapy for bronchial asthma in children and its effect on pulmonary function, serum IgA and IgE levels / 中国针灸

OBJECTIVE@#To observe the efficacy of acupoint thread-embedding combined with fluticasone propionate aerosol for chronic persistent bronchial asthma of lung-spleen @*METHODS@#A total of 120 children with chronic persistent bronchial asthma were randomly divided into an observation group (60 cases, 9 cases dropped off) and a control group (60 cases, 7 cases dropped off). The control group was treated with fluticasone propionate aerosol (125 μg per inhalation), twice a day; based on the control group treatment, the observation group was treated with acupoint thread-embedding at Dingchuan (EX-B 1), Feishu (BL 13), Zusanli (ST 36) and Danzhong (CV 17), once half a month. Both groups were treated for 3 months. The pulmonary function, serum IgA, IgE levels and TCM symptom score were compared between the two groups before and after treatment, and the clinical efficacy was evaluated.@*RESULTS@#After treatment, the large airway function (peak expiratory flow [PEF], forced expiratory volume at the first second [FEV1]) and small airway function (maximal expiratory flow at 25% of the forced capacity [MEF25%], maximal expiratory flow at 50% of the forced capacity [MEF50%], maximal expiratory flow at 75% of the forced capacity [MEF75%] and midexpiratory flow 25%-75% [MEF25%-75%]) were higher than those before treatment (@*CONCLUSION@#Acupoint thread-embedding combined with fluticasone propionate aerosol could improve the pulmonary function, TCM symptoms and serum IgA and IgE levels in children with chronic persistent bronchial asthma of lung-spleen

Clinical therapeutic effect on bronchial asthma in children of different body constitutions treated withplaster andplaster / 中国针灸

<p><b>OBJECTIVE</b>To observe the difference in the clinical therapeutic effects on bronchial asthma in children of different body constitutions treated withplaster andplaster.</p><p><b>METHODS</b>One hundred and twenty-two children of bronchial asthma were divided into three groups according to TCM body constitutions, 42 cases in thedeficiency constitution group, 40 cases in thedeficiency constitution group and 40 cases in the phlegm damp constitution group. From 2011 to 2013, the acupoint plaster was applied to all of the children in the three groups during the dog days and the third nine-day period after the winter solstice each year. The average attack frequency and onset days of bronchial asthma and relevant immune function indicators were observed during treatment and 1 year after treatment in the children and the therapeutic effects were evaluated.</p><p><b>RESULTS</b>①In 2014, the acute attacks of bronchial asthma were (1.2±0.9) times and (1.4±0.4) times in thedeficiency constitution group and thedeficiency constitution group, all lower than (3.0±0.5) times in the phlegm damp constitution group (both<0.05) separately. ②After treatment, in thedeficiency constitution group anddeficiency constitution group, the values of IgG, IgA and IgM were all increased as compared with those before treatment (all<0.05). ③The total effective rate was over 95% in the children of the three groups. The clinical control rates in thedeficiency constitution group and thedeficiency constitution group were higher apparently than that in the phlegm damp constitution group, indicating the significant difference statistically (both<0.05).</p><p><b>CONCLUSIONS</b>The combined treatment ofplaster andplaster are effective on bronchial asthma in the children of different body constitutions.

Study on Regulatory Mechanism and Regulation of Traditional Chinese Medicine on TRPV1 and Related Cytokines among Children Bronchial Asthma / 世界科学技术-中医药现代化

This study was aimed to explore regulatory mechanism of TRPV1 and related cytokines on children bronchial asthma and to study regulation of traditional Chinese medicine (TCM) on TRPV 1 and its related cytokines.Through KEGG database combined with literature search,the preliminary regulatory network of children bronchial asthma was drawn.And regarding the key nodes in the network,literature and database searches on related TCM were conducted.The results showed that the preliminary regulatory network was mapped out through KEGG database in combination with previous researches and literature search.Currently,studies had shown that emodin,baicalin,corydalis ambigua and dragon's blood had different degrees of downregulation effect on TRPV1.Yi-Shen Ping-Chuan Huo-Xue (YSPCHX)mixture suppresses the level of cytokine IL-2 and improves the level of cytokine IL-4 in a dose-dependent manner;astragalus mongholicus regulates the ratio of Th 1 to Th2,and Chuan-Fu-Ling (CFL) plaster elevates the level of IFN-γ.And both of them reduced the level of IL-4 in serum.It was concluded that the preliminary regulatory network of children bronchial asthma in this study provided certain basis for the regulatory mechanism of children bronchial asthma and treatment in TCM
