Objective To examine the levels of fractional exhaled nitric oxide in bronchial asthma and the cor-relation between fractional exhaled nitric oxide and pulmonary function tests as well as the value of pulmonary function tests in curing the children with bronchial asthma. Methods Seventy - two asthmatic children came from Guiyang Ma-ternal and Child Health Hospital were studied. They were divided into 2 groups:mild - to - moderate asthma group(36 cases)and serious asthma group(36 cases). Fractional exhaled nitric oxide level and the lung function were measured and the correlation analysis was analyzed by SPSS 13. 0 software. Results The fractional exhaled nitric oxide concen-tration of the serious asthma group was significantly higher than that of the mild - to - moderate asthma group[(47 ± 26)ppb vs(29 ± 15)ppb,t = 3. 543,P ﹤ 0. 01],1 - second rate,maximum mid - expiratory flow(MMEF),and peak expiratory flow(PEF)in mild - to - moderate asthma group were significantly higher than those in serious asthma group[(99. 74 ± 9. 81)% vs(87. 17 ± 13. 30)% ,(87. 12 ± 35. 61)% vs(68. 90 ± 30. 88)% ,(99. 97 ± 10. 83)% vs (94. 31 ± 17. 69)% ](P ﹤ 0. 01,0. 05,0. 05). No correlations were found between fractional exhaled nitric oxide level and the lung function parameters,including forced expiratory volume in 1s(FEV1),1 - second rate,MMEF and PEF in the mild - to - moderate asthma group(r = 0. 073,0. 087,0. 242,0. 326,all P ﹥ 0. 05). However the level of fractional exhaled nitric oxide was negatively correlated with the lung function parameters,including FEV1,FEV1 / FVC,MMEF and PEF in serious asthma group(r = - 0. 354,- 0. 573,- 0. 478,- 0. 471,P ﹤ 0. 05,0. 001,0. 005,0. 005),respec-tively. Conclusions Monitoring of fractional exhaled nitric oxide and the lung function parameters can effectively indi-cate the state of illness of asthmatic child,which plays a key role in the treatment.

Objective To detect the expressions of CD70 mRNA and protein and to determine the methylation status of CD70 gene promoter in T cells from patients with systemic lupus erythematosus (SLE).Methods Peripheral blood CD4+ and CD8+ T cells were isolated from 15 patients with active SLE,15 patients with inactive SLE and 15 healthy control subjects.Real-time quantitative reverse transcription-PCR was carried out to quantify the mRNA expression of CD70,flow cytometry to determine the frequency of CD4+CD70+ and CD8+ CD70+ T cells,and bisulfite sequencing to evaluate the methylation status of CD70 gene promoter in CD4+ and CD8+ T cells.Differences in these parameters among these groups were analyzed by one-factor analysis of variance and SNK-q test.Results Compared with the healthy controls,the patients with active SLE and inactive SLE showed a significant increase in CD70 mRNA expression in CD4+ T cells (0.82 ± 0.12 and 0.73 ± 0.11 vs.0.45 ±0.09,F =53.017,P ＜ 0.01) and in the frequency of CD70+CD4+ T cells (80.30％ ± 11.04％ and 66.80％ ± 3.98％ vs.12.48％ ± 3.45％,F =311.517,P ＜ 0.01).Also,the expression of CD70 mRNA in CD4+ T cells and the frequency of CD70+CD4+ T cells were significantly higher in patients with active SLE than in patients with inactive SLE (both P ＜ 0.05).There was a positive correlation between the frequency of peripheral CD70+CD4+ T cells and disease activity in SLE in these patients (r =0.792,P ＜ 0.01).The average methylation index of the region between-600 bp and-300 bp of CD70 gene promoter in CD4+ T cells was 0.32 ± 0.05 and 0.36 ± 0.05 respectively in the patients with active and inactive SLE,significantly lower than that in the healthy controls (0.62 ± 0.05,F =152.64,P ＜ 0.01),and the patients with active SLE showed a significantly lower methylation index than those with inactive SLE (P ＜ 0.05).Conclusions The CD70 gene promoter in CD4+ T cells is significantly hypomethylated in patients with SLE,which may directly lead to the overexpression of CD70.

To propose a formula method of medicated diet based on medicinal property combination patterns in this paper under the context of lack of innovation in medicated diets. By analyzing the property combination patterns of traditional Chinese medicine and commonly used foods recorded in the pharmacopoeia, medicated diet formulae were optimized by using the greedy algorithm, with the property combination patterns of classical formulae based on the syndrome differentiation and treatment. In this paper, the Baihu Rensheng decoction, which is a classical formula for treating lung and stomach heat-derived diabetes, was taken for example in the formula design. As a result, totally 18 medicated diet formulae were developed and proved to be rational in the analysis on traditional Chinese medicines and nutriology. This method expands the way of thinking for personalized diet therapies and provides theoretical basis the industrial development and clinical application of medicated diets.

Objective To analyze the genetic model of attention deficit hyperactivity disorder(ADHD).Methods The segregation analysis and polygenic multiple threshold model were used to prove the polygenic model and to estimate the heritability and recurrence risk of ADHD in each degree relatives.Results 1. The average heritability of ADHD was (102.47?9.78)%;2.The first-degree relatives of probands were in high risk for ADHD(23.0%)compared with colony prevalence rate(2.6%). The ADHD prevalence of each degree relatives rapidly decreased with the increased magnitude of consanguineous relationship of each degree relatives and ADHD probands. Conclusions The genetic model of ADHD is the most likely polygenic inheritance with major genes, which suggested that the genetic factor might play an important role in the liability variance of ADHD.Apart from the involvement of multiple genes,each gene contributes a small additive effect,and the major genes may be involved as well.
