ABSTRACT

Objective:To explore the clinical efficacy and the effects on serum inflammatory factors of carbocisteine and budes-onide in the treatment of asthma. Methods:Totally 186 asthma patients were randomly divided into the observation group (93 cases) and the control group (93 cases). The control group received budesonide combined with the conventional treatment, the observation group was treated with carbocisteine and budesonide, and one week was a treatment course. The efficacy was observed. The airway re-sponsiveness and cough condition was respectively assessed by early respiratory resistance ( Rrsc) and Leicester cough questionnaire ( LCQ) . The improvement of day and night symptoms was observed, and the serum levels of inflammatory factors and the safety were also evaluated. Results:LCQ score of the observation group after the treatment was significantly higher than that of the control group, Rrsc score for day and night symptoms and serum IL-8, TNF-αand IgE levels were significantly lower than those in the control group, and the differences were statistically significant (P0. 05). The difference in the in-cidence of ADR between the groups was not statistically significant (P>0. 05). Conclusion: Carbocisteine and budesonide in the treatment of asthma can significantly improve asthma symptoms and reduce cough and inflammatory cytokines with promising safety.

ABSTRACT

Objective To understand the underlying mechanism of mites-induced pediatric asthma by bioinformatic analysis on speciifc microRNA (miRNA) array and target gene screening. Methods This is a case control study of 62 pairs of dust mites-induced asthma children with age and gender matched healthy controls. Twelve pairs were randomly selected for miRNA array. The abnormal expression of miRNAs was compared between asthma and control children. The results were validated by RT-qPCR and bioinformatic analysis in remaining pairs of children. Results Six miRNAs (miRNA-151a-5p, 625-5p, 126-3p, 513a-5p, 27b-3p, 22-3p) were signiifcantly down-regulated more than two folds in dust mites-induced asthma children than those in controls. The enriched bioinformatics analysis showed that these miRNAs and their target genes CBL, PPARGC1B, ESR1, ONECUT2, EGFR, SYK, and STAT1 were related to inlfammatory cytokine signaling pathway. Conclusion It is suggested that miR-22-3p, 513a-5p, 625-5p, 27b-3p, and miRNA-target genes form a network through co-regulation to target genes to participate dust mites-induced asthma in children.

ABSTRACT

<p><b>OBJECTIVE</b>This study aims to observe the expression of Sclerostin during movement of orthodontic teeth and determine the effect of this protein on remodeling of periodontal tissues.</p><p><b>METHODS</b>Twenty-four Wistar rats were chosen. Orthodontic forces were applied between the bilateral incisor and first molar to achieve mesial movement. Rats in each group were executed at different time points (0, 1, 3, 5, 7, 14 d). Morphology of periodontal tissue was observed by hematoxylin-eosin (HE) staining. The number of osteoclasts were observed by tartrate-resistant acid phosphatase (TRAP) staining. Sclerostin expression were observed by immunohistochemical staining.</p><p><b>RESULTS</b>HE staining revealed that the resorption of alveolar bone intensified with prolonged movement. Results of immunohistochemical and TRAP staining revealed that Sclerostin expression and number of osteoclasts were related to duration of movement of orthodontic tooth. After staining for 5 days, the number of osteoclasts and Sclerostin expression reached their peak and then began to decline. The numbers of osteoclasts and the expression level of Sclerostin were higher at the compressive side than those at the tensive side.</p><p><b>CONCLUSION</b>Sclerostin affected orthodontic tooth movement by inhibiting the Wnt signaling pathway and by indirectly or directly controlling bone morphogenetic protein.</p>

ABSTRACT

Abstract] Objective To analyze the molecular characteristics of the full-length genome of a new-ly isolated genotypeⅤJapanese encephalitis virus (JEV) strain (XZ0934) in China and the first genotypeⅤJEV strain ( Muar) isolated in Malaya 60 years ago.Methods Several softwares including ClustalX 2.0.9, DNAStar 7.1, Bioedit 7.2.5 and MEGA6.06 were used to conduct sequence alignments and phylo-genetic analysis.Results The full-length genomes of XZ0934 strain (isolated in Tibet, China in 2009) and Muar strain (isolated in Malaya in 1952) were composed of 10 983 and 10 988 nucleotides, respective-ly.The XZ0934 strain was highly similar with the Muar strain showing the homology of 90.6%in nucleotide (nt) and 98.3%in amino acid (aa).The open reading frame (ORF) of the two genotype Ⅴ JEV strains encoded 3433 aa while the ORF of other four genotypes (Ⅰ-Ⅳ) (10 299 nt) encoded 3432 aa.Compared with JEV strains of other genotypes, a serine were inserted into the NS4A gene of JEV strains genotype Ⅴand 10-14 nucleotides were inserted into the downstream of the ORF stop codon in 3′-untranslated region. Phylogenetic analysis of E sequences of all JEV strains genotypedⅠ-Ⅴrevealed that in the cluster of geno-typeⅤ, XZ0934 and 10-1827 ( isolated from mosquitoes in South Korea, 2010) stains formed a branch and were divergent from that of Muar strain indicating that there were molecular genetic differences among geno-typeⅤJEV strains after a 60 years hiatus.Conclusion The two genotypeⅤJEV strains showed high lev-els of identity in nucleotide sequences and amino acid sequences with serine insertion in the NS4A gene. However, there were molecular genetic differences between genotypeⅤJEV strains isolated after a 60 years hiatus.

ABSTRACT

BACKGROUND:Compared with the conventional composite resin materials, large pieces of filing composite resin materials have the features of increasing light-curing depth, decreasing the polymerization shrinkage rate and streamlining operational procedures; however, the properties of different types of large pieces of filing composite resin materials are different. OBJECTIVE:To analyze the hardness and bond strength of four kinds of composite resin materials. METHODS: Large pieces of filing composite resin Tetric EvoCeram Bulk Fil, SDR, as wel as conventional composite resin P60, Z350 were obtained. The vickers microhardness of these four kinds of composite resin materials under the light-curing depth of 2, 3, 4, 5 mm was detected. The shear bond strength between these four kinds of composite resin materials and the dentin was also detected. RESULTS AND CONCLUSION:The hardness order under different light-curing depths was: P60 composite resin > Z350 composite resin > Tetric EvoCeram BulkFil composite resin > SDR composite resin, there was a significant difference between these four groups (P < 0.05). The light-cured hardness of Tetric EvoCream BulkFil and SDR composite resins was not significantly decreased with the increased cured depth. The shear bond strength of Tetric EvoCeram BulkFil and SDR composite resins was significantly higher compared with the P60 and Z350 composite resins (P < 0.05). These results demonstrate that large pieces of filing resinous materials, Tetric EvoCeram BulkFil and SDR, show better comprehensive mechanical properties and have a higher shear bond strength.

ABSTRACT

A low-cost, simple, sensitive detection method of lactate dehydrogense ( LDH) was developed on paper-based microwell arrays microfluidic device. The phenazine methyl sulfate/nitrotetrazolium blue chloride ( PMS/NBT) detection system was used for LDH detection and the colorimetric results were recorded by both Gel Documentation System and a common camera. Under the optimized conditions, the colorimetric intensity showed a linear correlation to the activity of LDH in the range of 10 to 150 U/L with a limit of detection (LOD) of 9. 44 U/L (3σ) by Gel Documentation System;and the linear range was 15-150 U/L by camera with a LOD of 12. 36 U/L (3σ). Foremost, it was found that human serum albumin (HSA) had an effect on the colorimetric enhancement in this detection system. This low-cost, portable paper-based analytical platform could be suitable for the application in the point-of-care with high sensitivity and reproducibility.

ABSTRACT

Objective To study the effect of Dachengqi decoction on expression of triggering receptor on myeloid cell 1(TREM-1)in septic rats in order to further provide a theoretical basis concerning the mechanism of this decoction for treatment of sepsis. Methods 100 male Sprague-Dawley(SD)rats were randomly divided into five groups:normal control,sham operation,sepsis model,low-dose and high-dose Dachengqi decoction groups (each,n=20). The sepsis models were reproduced by cecal ligated perforation(CLP). The low-dose and high-dose Dachengqi decoction groups were lavaged separately by low dose(5 mL/kg)and normal dose(10 mL/kg)Dachengqi decoction at 2 hours before CLP and after CLP twice per day(interval 8 hours),and the other three groups were lavaged with 10 mL/kg normal saline. Five rats in each group were killed randomly at the time points of 6,12,24,48 hours after CLP;the abdominal aorta blood and the liver tissue were collected. The plasma levels of TREM-1,interleukin-6 (IL-6),tumor necrosis factor-α(TNF-α)were tested by enzyme linked immunosorbent assay(ELISA). The expression level of TREM-1 mRNA in the liver was measured by reverse transcription - polymerase chain reaction (RT-PCR). Results Compared with normal control group and sham operation group, the plasma levels of TREM-1, IL-6, TNF-α and the expression of liver TREM-1 mRNA were increased significantly in model group. Compared with model group,the above indexes in low-dose and high-dose Dachengqi decoction groups were reduced obviously,the changes being more marked in the high-dose group;the levels of TREM-1,IL-6 at 6 hours after operation and the levels of TNF-αand TREM-1 mRNA at 24 hours after operation in high-dose group were lower than those of low-dose group〔6 hours TREM-1(ng/L):179.19±4.43 vs. 213.86±2.84,6 hours IL-6 (ng/L):136.80±7.70 vs. 162.90±3.87;24 hours TNF-α(ng/L):71.61±5.07 vs. 108.53±6.29,24 hours TREM-1 mRNA:24.33±3.16 vs. 27.22±3.34,all P<0.05〕. Conclusion The partial mechanism of the efficacy of Dachengqi decoction for treatment of sepsis was probably related to the inhibition of TREM-1 expression.
