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.

A strain with relative higher phytase-producing ability, Aspergillus fumigatus WY-2 was screened from soil. The optimal pH and temperature for activity of the phytase from A.fumigatus WY-2 were 5.5 and 55 ℃, respectively. The gene encoding the phytase was amplified from genomic DNA of the strain by PCR, and a 1.5 kb DNA fragment was obtained and then was cloned into vector pMD18-T. The sequencing analysis revealed that the DNA fragment contained a whole open reading frame (ORF) of phytase gene. The phytase gene was 1459 bp in length included with a 61 bp intron and encoded 465 amino acids. A signal peptide encoding 26 amino acids was found at 5′end of the gene. There were 7 potential glycosylation sites in the phytase. The present phytase showed 91% identity in nucleotide sequence and 91% identity in deduced amino acids sequence to the previously reported A.fumigatus ATCC34625 phytase.

Aim & methods The antagonism of L-dicentrine to contraction of isolated porcine coronary artery strips induced by 5-HT KCl and Ca2+ was observed with U-135 electrophsiological recorder.Results The contractions induced by 5-HT KCl and Ca2+ after high K+ depolarization in the strips of porcine coronary artery were markediy inhibited by L-dicentrine.L-dicentrine significantly depressed maximal response and caused rightward displacement of the dose -response curve. Showing a non-competitive antagonism. In Ca2+ free solution,L-dicentrine inhibited 5-HT-induced contraction of porcine coronary artery,which is dependent on Ca2+ relesed from intracellular store. After Ca2+ concentration in bath solution was restored,L-dicentrine did not influence the contraction of porcine coronary artery depending on extracellular Ca2+.Conclusion L-D have significant relaxation on porcine coronary artery ,which possibly has 5-HT receptor and histamine receptor.
