Objective:To identify the impact on asthma by the treatment of mometasone furoate monohydrate nasal spray to allergic rhinitis.Methods:This was an opened own control study.25 patients with asthma and rhinitis were given inhaled-powder salmeterol/fluticasone50 ?g/250 ?g(Seretide),one inhalation each time,twice daily via Diskhaler for 3 months.then added the use of mometasone furoate monohydrate nasal spray(Nasonex) 50 ?g,one spray each nasal side each time,twice daily.To determine the efficacy of different treatment methods.The forced expiratory volume in one second(FEV1),the forced vital capacity(FVC),asthma symptom scores,nocturnal-awakening times and the amount of use of inhaled short-acting?2-adrenoceptor agonist bronchodilators were observed respectively before the treatment,after the treatment of salmeterol/fluticasone 50 ?g/250 ?g for 3 months,and after the treatment of inhaled-powder salmeterol/fluticasone combined with Nasonex for 3 months.Results:The treatment of inhaled-powder salmeterol/fluticasone combined with mometasone furoate monohydrate nasal spray improved FEV1,FVC and clinical asthma symptoms,and decreased the amount of the use of inhaled short-acting?2-adrenoceptor agonist bronchodilators,there were significant differences(P

Objective To investigate the clinical therapeutic effects of neuromuscular electric stimulation (NMES) on patients with swallowing disorders after stroke. MethodsA total of 98 patients with a swallowing disorder after stroke were randomly divided into an NMES group (38 cases),a rehabilitation group (30 cases) and a control group (30 cases).In the control group the patients were treated with medication only; the in rehabilitation group they were treated with medication and swallowing rehabilitation training; in the NMES group they were treated with medication and NMES.The treatments lasted for 3 weeks in all groups.The swallowing function of patients in each group were observed and assessed with dysphagia scoring pre-and post-treatment.Complications of the swallowing disorders,side effects of treatment and the stomach tube leaving rate were observed. ResultsAfter treatment,the dysphagia scores of patients in the NMES and rehabilitation groups both increased,but the average scores in the NMES group were significantly higher than in the rehabilitation and control groups.The difference in therapeutic effect between the three groups was statistically significant.After treatment,the incidence of aspiration pneumonia in the NMES group was significantly lower than that in the control and rehabilitation groups.The average stomach tube leaving rate in the NMES group was significantly lower than that in the control group,but there was no significant difference in stomach tube leaving rates between the rehabilitation group and the NMES group.There was no significant difference among the three groups in malnutrition.No side effect was observed in any group.Conclusions NMES could alleviate post-stroke dysphagia and decrease the incidence of aspiration.The short-term therapeutic effect of NMES was better than that of swallowing rehabilitation training,but the long-term therapeutic effects were about the same in the two groups.

OBJECTIVEThis study aims to test the accuracy and precision of iWitness photogrammetry for measuring the facial tissues of mannequin head.

METHODSUnder ideal circumstances, the 3D landmark coordinates were repeatedly obtained from a mannequin head using iWitness photogrammetric system with different parameters, to examine the precision of this system. The differences between the 3D data and their true distance values of mannequin head were computed.

RESULTSOperator error of 3D system in non-zoom and zoom status were 0.20 mm and 0.09 mm, and the difference was significant (P 0.05). Image captured error of 3D system was 0.283 mm, and there was no significant difference compared with the same group of images (P>0.05). Error of 3D systen with recalibration was 0.251 mm, and the difference was not statistically significant compared with image captured error (P>0.05). Good congruence was observed between means derived from the 3D photos and direct anthropometry, with difference ranging from -0.4 mm to +0.4 mm.

CONCLUSIONThis study provides further evidence of the high reliability of iWitness photogrammetry for several craniofacial measurements, including landmarks and inter-landmark distances. The evaluated system can be recommended for the evaluation and documentation of the facial surface.

Objective To investigate the effects of azithromycin on airway remodeling and the expression of transforming growth factorβ1 (TGF-β1) in asthmatic mice.Methods BALB/c male mice were random divided into 3 groups:control group(A),asthma group (B),and azithromycin treated group (C),with 10 mice in each group.Bronchoalveolar lavage fluid was collected to count the number of white blood cells and eosinophilic granulocytes EOS.The morphological parameters of the bronchi were measured by computer image analysis and the pathologic changes of the bronchi and lung tissue were observed by HE staining.The expressions of TGF-β1 were detected by immunohistochemistry.Results The number of EOS in B group was significantly higher than that in control group(8.12 ±0.54 vs 0.70 ±0.40;8.12 ±0.54 vs 0.87 ±0.25,P ＜0.01).WAt and WAi and WAm in group C was significantly lower than that in group B (10.15 ±0.95 vs 15.36 ±0.85,4.16 ±0.32 vs 10.64 ± 1.03,3.77 ±0.15 vs 7.97 ±0.17,P ＜0.01)but higher than that in group A.The expression of TGF-β1 in group C was significantly lower than that in group B but higher than that in group A.TGF-β1 expression of lung tissue in C group was significantly correlated with EOS,(r =0.840,P ＜0.01) and WAt(r =0.735,P ＜0.01) and WAm (r =0.870,P ＜0.01).Conclusion Azithromycin inhibited airway remodeling in asthmatic mice,which might possibly be achieved through inhibiting the expression of TGF-β1.

Objective To investigate the correlation between heat-shock protein 70-2 (HSP70-2) gene+1267A/G polymorphism and coronary heart disease (CHD) in Han Chinese population. Methods Using the method of polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) , the polymorphism and genotype and allele distribution of HSP70-2 gene + 1267A/G in 185 CHD patients and 149 controls were analyzed. Results The HSP70-2 gene + 1267A/G polymorphism was found in this study population.The distribution of HSP70-2 genotypes was in Hardy-Weinberg equilibrium. The frequency of G allele in CHD group was significantly higher than that in control (61.89% vs51.68%, P ＜ 0. 01). After multiple logistic regression analysis, HSP70-2 gene (GG + AG) genotype was an independent risk factor of coronary heart disease. Conclusion HSP70-2 gene + 1267A/G polymorphism was associated with CHD risk of Han Chinese population, the G allele might serve as a genetic risk factor of coronary heart disease.

Objective To investigate the expression of connective tissue growth factor( CTGF) and the effects of azithromycin in airway remodeling in asthmatic mice.Methods BALB/c female mice were randomly divided into 3 groups;control group(A),asthma group(B) ,and azithromycin treated group(C),with 10 mice in each group.Mice were sensitized and challenged continually with ovalbumin( OVA).The distribution and types of collagens were detected by cirius red staining.Lung hydroxyproline content was determined by acid hydrolysis.CTCF expression in mice pulmonary tissues was detected by SABC immunohistochemistry.Results After continual challenging with OVA,collagen hyperplasia was found in the airway wall and CTCF positive expression in airway epithelium.CTCF expression was closely associated with lung hydroxyproline content(r = 0.65,P <0.01).Conclusion Asthma continually challenged with OVA could result sub-epithelial fibrosis and remodeling in airway,which could be associated with the upregulation of CTCF over-expression.Azithromycin inhibited airway remodeling in asthmatic mice,possibly by inhibiting the expression of CTGF.

We have cloned full-length MDR1 cDNA from human normal liver tissue in previous study. Using this MDR1 cDNA as probe, we observed the MDR1 gene expression in human hepatocellular carcinoma treated with and without chemotherapy by Northern blot. The results showed that expression of MDR1 gene in hepatocellular carcinoma tissues was higher than that in their adjacent normal liver tissues; and enhanced MDR1 gene expression was also observed in hepatocellular carcinoma treated with chemotherapic agents. We also explored a method for quantitative analysis of MDR1 gene expression in hepatocellular carcinoma by polymerase chain reaction. This study suggests that overexpression of MDR1 gene may be responsible for the intrinsic and acquired drug resistance of human hepatocellular carcinoma, and PCR is a preferable method for quantitative analysis of MDR1 gene expression in hepatocellular carcinoma.

Objective To explore the effect of expression of protein kinase C receptor 1(RACK1) induced by lipopolysaccharide (LPS) on Sonic hedgehog(SHH) signaling pathway in rat puhnonary microvascular endothelial cells (RPMVEC).Methods The healthy male SPF grade SD rat with 100-120 g body weight were gotten from the laboratory animal center of Anhui province.Using immunocytochemistry method,the expression of RACK1 protein in RPMVECs was detected,cultured RPMVECs were randomly divided into different groups as LPS dose-dependent group,SAG(smoothened Agonist,a SHH signaling pathway specific agonist) dose-dependent group,LPS time-dependent group,SAG time-dependent group and LPS+SAG group.In LPS dose-dependent groups,RPMVECs were cultured with 0.1,1,10 mg/L LPS for 8 h.In LPS time-dependent groups,RPMVECs were cultured with 10 mg/L LPS for 0,2,4,8,12,24 h.In SAG dose-dependent groups,RPMVECs were cultured with 0.1,1,10 μ mol/L for 8 h.In SAG time-dependent groups,RPMVECs were cultured with 1 μ mol/L SAG for 0,2,4,8,12,24 h.In LPS+SAG group,RPMVECs were cultured with 1 μ mol/L SAG 8 h after 10 mg/L LPS treatment for 1 h.In addition,blank group,LPS group and SAG group were set for control.Western blot were used to detect the level of RACK1 and RT-PCR were used to detect the expression of GLI-1 mRNA after intervention.Results Immunocytochemistry revealed that RACK1 were present in RPMVEC.1.In LPS dose-dependent groups (0,0.1,1,10 mg/L),the level of RACK1 elevated as LPS dose increased correspondingly with inter-group difference (P＜0.05);the relative expression levels of GLI-1 mRNA were (1.109 + 0.063),(1.039 + 0.135),(0.813 ± 0.066),(0.770 + 0.105),(1 mg/L vs.10 mg/L,P＞0.05;the rest P＜0.05).In LPS time-dependent groups,the relative expression level of RACK1 at 2 h (0.370 + 0.010) was higher than that at 0 h (0.329 ± 0.008),peaked at 12 h (1.296 ± 0.048),and compared with 0 h,there was significant differences (F=1 272.204,P＜0.05).The relative expression level of GLI-1 mRNA was decreased at 2 h (0.929 ±-0.007),and compared with 0 h(1.089 ± 0.042),there was significant differences (F=306.609,P＜0.05).2.In SAG dose-dependent groups,there was no significant difference in level of RACK1 between groups(all P＞0.05).The relative expression levels ofGLI-1 mRNA were (1.109 ± 0.063),(1.169 ± 0.052),(3.468 ± 0.128),(3.434 ± 0.054),(0 μ mol/L vs.0.1 μ mol/L and 1 μ mol/L vs.10 μ mol/L,P＞0.05,the rest P＜0.05).Among SAG time-dependent groups,there was no significant difference in levels of RACK1 protein(P＞0.05).The relative expression level of GLI-1 mRNA increased at 2 h (3.027 ± 0.065),and compared with 0 h (2.651 + 0.123),there was significant differences (F=132.841,P＜0.05).3.In LPS+SAG intervention groups,the expression of RACKI was lower than that in LPS group (0.831 ±0.040 vs.1.189 ± 0.149,P＜0.05),and the expression of GLI-1 mRNA was higher than that in LPS group (2.720 + 0.130 vs.0.796-4-0.082,P＜0.05).Conclusions The LPS up-regulates the expression of RACK1 in RPMVECs,and the activated SHH signaling pathway can down-regulate the expression of RACK1 induced by LPS in RPMVECs.
