Influence and Effect of Acupoint Application of Chinese Medicine on Height and Bone Age of Children with Short Stature.

OBJECTIVE: To explore the effect of acupoint application of Chinese medicine on children's height and bone age. METHODS: Altogether, 120 children with a short stature treated in our hospital from September 2017 to September 2018 were divided into the control group (CG, n = 60) and the observation group (OG, n = 60) according to the random number table method. The children in CG were given healthy diet and exercise plans and supplemented with daily vitamin intake. The OG was treated with acupoint application of Chinese medicine on the basis of the CG. The clinical efficacy of the CG and the OG of children after treatment was observed. The height increment, growth rate, and bone age of children were compared before and after treatment. The levels of IGF-1 and 25-(OH)D in the serum of children before and after treatment were tested. According to the clinical curative effect after treatment, the children were divided into good curative effect group (markedly effective + effective) and poor curative effect group (ineffective). Logistics regression analysis was applied to analyze the risk factors. RESULTS: Compared with the CG, the curative effect on the OG was evidently improved (P < 0.05). In addition, the height increment, the growth speed, and the bone age of the OG increased evidently (P < 0.05). Compared with the CG, the expression of IGF-1 and 25-(OH)D of the OG elevated (P < 0.05). Serum IGF-1 and 25-(OH)D concentrations were positively correlated with growth rate and bone age (P < 0.05). Risk factors analysis showed that disease course, IGF-1, 25-(OH)D expression, and heredity were the risk factors affecting the curative effect on children. CONCLUSION: Acupoint application of Chinese medicine has effect on the height and bone age of children with short stature, which is worthy of clinical promotion. In addition, early treatment should be carried out to improve the clinical efficacy of children.

Serum Cytokines and FeNO in School-Aged Children with Mycoplasma pneumoniae Pneumonia.

BACKGROUND Mycoplasma pneumoniae is a major cause of community-acquired pneumonia (CAP) that is particularly prevalent in school-aged children. This study explored the potential involvement of cytokines in children with Mycoplasma pneumoniae pneumonia (MPP) infection. MATERIAL AND METHODS Children aged 3-7 years who were hospitalized due to CAP infection were enrolled and divided into 2 groups: an MPP group (n=33) and a NMPP group (n=38), along with 21 age-matched healthy controls. Clinical characteristics and laboratory data were recorded. Serum levels of IL-18, IL-33, IFN-γ, IL-5, IL-6, IL-8, and IL-13 were assessed using Luminex xMAP technology. Correlation analysis and ROC curves analysis were also performed to further explore the role of these detected cytokines in CAP. RESULTS Compared with the healthy controls, the serum expression of IL-18, IL-33, IFN-γ, IL-5, IL-6, IL-8, and IL-13 were significantly higher in the MPP and NMPP groups. Furthermore, serum IL-18 expression was found to be significantly correlated with lgE, FeNO, IL-5, IL-8, and IL-13 concentrations. Significant differences were also observed between the MPP group and NMPP group patients in levels of IL-18, IL-5, and IL-6, and further ROC analysis showed that the area under the curve (AUC) of IL-18 and IL-5 were 0.813 (95% CI: 0.710-0.917; P<0.01) and 0.844 (95% CI: 0.756-0.933; P<0.01), respectively. CONCLUSIONS IL-18, IL-33, IFN-γ, IL-5, IL-6, IL-8, and IL-13 serum levels showed significant differences in children with CAP. IL-18 and IL-5 were much higher in the MPP group compared to the NMPP group patients, whereas IL-6 levels were significantly lower in these 2 groups.

Angiotensin-converting enzyme insertion/deletion polymorphism and susceptibility to pediatric asthma: A meta-analysis.

OBJECTIVE: The correlation of the angiotensin-converting enzyme (ACE) insertion/deletion (I/D) polymorphism with pediatric asthma risk was assessed in this meta-analysis. METHODS: PubMed, Web of Science, Embase and CNKI databases were systematically searched for relevant literature, followed by application of odds ratios (OR) along with 95% confidence interval (CI) for determining the strength of relationship. RESULTS: Seven articles with 802 cases and 632 controls fulfilled the inclusion criteria. As a result, the ACE I/D polymorphism was related to elevated pediatric asthma risk (D vs I: OR = 1.87, 95% CI = 1.59-2.20; dominant model: OR =1.53, 95% CI = 1.28-1.81; recessive model: OR =1.54, 95% CI = 1.28-1.85; DD vs II: OR =2.95, 95% CI = 2.19-3.98; DI vs II: OR = 0.96, 95% CI = 0.78-1.19). Subgroup analysis stratified by race revealed significant interrelation in Asians. CONCLUSION: This meta-analysis demonstrated that the ACE I/D polymorphism might be related to the risk of pediatric asthma.

[Study on negative expiratory pressure technique in children with bronchial asthma].

OBJECTIVE: To investigate the clinical significance of children bronchial asthma detection by using negative expiratory pressure (NEP) technique. METHODS: The children with bronchial asthma admitted to Department of Pediatrics of Zhejiang Provincial Integrated Traditional Chinese and Western Medicine Hospital from March 2016 to March 2018 were enrolled. They were divided into mild group (0-4 scores) and severe group (5-12 scores) according to asthma clinical scoring criteria. The children undergoing physical examination at the same period were served as healthy control group. NEP technique and tidal volume (VT) were detected by the pulmonary function instrument. Respiratory flow-volume curves (F-V curves) without NEP were compared with tidal F-V curves after NEP application to assess expiratory flow limitation (EFL). EFL index was calculated according to the percentage of expiratory VT after EFL and expiratory VT when NEP was not used. Pearson correlation method was used to analyze the relationship between EFL index and severity of bronchial asthma. Receiver operating characteristic (ROC) curve was plotted to analyze the value of EFL index in evaluating the severity of bronchial asthma in children. RESULTS: A total of 86 children with bronchial asthma were enrolled in the study, and 84 patients completed the test and 2 children withdrew due to other diseases. Finally, 84 patients were included in the final analysis, including 41 mild and 43 severe children. Forty-two healthy children in the same period were served as healthy control group. There was no significant difference in gender or age among the groups, and no adverse reactions occurred during the test. The EFL index of children with bronchial asthma was significantly higher than that of the healthy control group, and it was increased with the severity of the disease [mild group compared with healthy control group: (30.60±6.03)% vs. (6.64±2.37)%, severe group compared with healthy control group: (33.70±5.41)% vs. (6.64±2.37)%, both P < 0.05]. There was no significant difference in respiratory rate (RR) or VT between mild group or severe group and healthy control group [RR (times/min): 31.45±4.18, 32.81±4.07 vs. 31.97±4.01, VT (mL/kg): 6.29±1.14, 5.96±0.90 vs. 6.30±1.20, all P > 0.05]. It was shown by the correlation analysis that EFL index was positively correlated with the severity of asthma (r = 0.836, P = 0.000). It was shown by ROC curve analysis that the area under ROC curve (AUC) of EFL index for predicting the severity of bronchial asthma in children was 0.801 [95% confidence interval (95%CI) = 0.725-0.878]; when the best cut-off value of EFL index was 29.21%, the sensitivity was 85.7%, the specificity was 69.2%, the positive predictive value was 75.1%, and the negative predictive value was 60.2%. CONCLUSIONS: The EFL index measured by NEP technology was closely related to the severity of bronchial asthma. The higher the EFL index, the more serious of the condition. The severity of bronchial asthma could be early judged by EFL index, which provided a basis for the evaluation and treatment of bronchial asthma.

Fangjing decoction relieves febrile seizures-induced hippocampal neuron apoptosis in rats via regulating the Akt/mTOR pathway.

Background: Fangjing decoction is a Traditional Chinese Medicine that exhibits anticonvulsive effects in treating febrile seizures (FS). Its action mechanism and the regulation on Akt/mammalian target of rapamycin (mTOR) pathway were revealed in the present study.Methods: FS model was established in Sprague-Dawley rats with or without Fangjing decoction treatment. On day 5, following initiation of drug treatment, seizures were monitored. Hippocampal neuron apoptosis was assessed using terminal dUTP nick end-labeling method. The levels of Bax, protein kinase B (Akt), phospho-Akt (p-Akt), mTOR, and p-mTOR proteins were analyzed using Western blotting. The content of hippocampal γ-aminobutyric acid (GABA) was measured by using ELISA assay.Results: Compared with the control group (n=8), Fangjing decoction effectively prolonged the latency but shortened the duration of FS in rats (n=8). Concomitantly, the apoptosis of hippocampal neurons, as well as Bax protein levels were also decreased in FS rats which were treated with Fangjing decoction. In addition, the Akt/mTOR signaling was found to be activated in rat hippocampus following FS, as evidenced by increased p-Akt and p-mTOR, while Fangjing decoction could inhibit the activation of Akt/mTOR signaling. Furthermore, the low GABA content in rat hippocampus following FS was significantly elevated by Fangjing decoction treatment. More importantly, SC79, a specific activator for Akt, apparently attenuated the protective effects of Fangjing decoction on FS rats.Conclusion: These results suggest that Fangjing decoction protects the hippocampal neurons from apoptosis by inactivating Akt/mTOR pathway, which may contribute to mitigating FS-induced brain injury.

ABCB1 Polymorphisms and Childhood Acute Lymphoblastic Leukemia Risk: A Meta-Analysis.

The association between ATP-binding cassette subfamily B member 1 (ABCB1) C3435T and C1236T polymorphisms and the risk for childhood acute lymphoblastic leukemia (ALL) is inconclusive. We conducted a meta-analysis of all published studies to determine the association of ABCB1 C3435T and C1236T polymorphisms and pediatric ALL risk. A systematic retrieval of relevant publications from the PubMed and Web of Science databases was performed. Data were calculated and statistical analysis was performed using STATA version 12.0 software. Metaanalysis results showed no significant association between C3435T polymorphism and pediatric ALL risk (TT vs. CC: odds ratio [OR] = 1.20, 95% confidence interval [CI] = 0.95-1.52; CT vs. CC: OR = 1.00, 95% CI = 0.82-1.23; the dominant model: OR = 1.07, 95% CI = 0.89-1.29; the recessive model: OR = 1.17, 95% CI = 0.84-1.62). Similarly, there was no association found for the C1236T polymorphism (TT vs. CC: OR = 1.18, 95% CI= 0.82-1.70; CT vs. CC: OR = 1.08, 95% CI = 0.80-1.45; the dominant model: OR = 1.10, 95% CI= 0.83-1.46; the recessive model: OR = 0.98, 95% CI = 0.61-1.58). Similar results were observed in the subgroup analyses on ethnicity and Hardy-Weinberg equilibrium. The present meta-analysis found no evidence for ABCB1 C3435T and C1236T polymorphisms as risk factors for pediatric ALL.
