0 05) After one year,plasma cortisol of the patients in either inhaled FP 500 ?g group or 750 ?g group was within normal rang Conclusions Long term inhaled FP with 500 ?g to 750 ?g per day is effective in moderate to severe asthma patients and has no significant suppression on adrenal cortex function

Objective:To study the master iodine nutrition status of population living in areas with different iodine in drinking water and the cut-off point of stopping iodized salt supply and the range of adequate iodine intake for the strategy of prevention from iodine deficiency or excess. Method:Thirteen townships points along the Yellow River downstream in Shandong were investigated and divided into six groups(A-F) based on water iodine concentrations of 0-50,50-100,100-150,150-300,300-800 and over 800 ?g/L. The indicators of water iodine,edible salt iodine,urinary iodine(UI) and thyroid goiter were observed. Results:From A,B,C,D,E and F group,the medians of water iodine concentration were 20.3,91.4,143.2,203.6,341.9 and 812.3 ?g/L,of edible salt iodine were 0,25.7,25.8,30.4,36.4 and 33.0 mg/kg,and of UI were 116.8,354.2,400.4,607.9,881.3 and 1 213.8 ?g/L respectively. The goiter rates were 10.8,8.6,15.0,14.2,14.9 and 25.0 % respectively . The sample proportion of UI below 100 ?g/L was 8.2%,of 100-300 ?g/L was 18.2% and of over 300 ?g/L was 73.6%. Frequency excursion of UI had a high trend towards water iodine concentration over 90?g/L in 5 groups. The proportion of UI over 300 ?g/L increased,consistent with higher water iodine level. Median UI of all groups with iodized salt decreased significantly,especially group F. There were significant correlations between UI and water iodine. Iodine nutrition status was markedly excessive in group B,C,D,E and F. Conclusions:Iodine nutrition status of most residents consuming drinking water with iodine concentration about 20 ?g/L should be adequately supplied with eligible iodized salt. Iodine intakes in groups B-F were excessive,and iodized salt supply should be stopped there. The cut-point of water iodine level where iodized salt stopped could possibly be 90 ?g/L,and the range of adequate iodine intake,in terms of drinking water,could be defined at range of over 20 to 90 ?g/L in iodine concentration.

The effect of gonadotropin-releasing hormone analogue(GnRHa) on lineafity growth and final height in 82 girls with central precocious puberty (CPP) was evaluated. The growth velocity in the second year was positively correlated with the difference value of bone age between the first year and the second year after treatment. The height standard deviation score for bone age and predicted aduh height increased after treatment. Twenty-six girls who had been followed to final height obtained better adult height than target height. GnRHa in combination with aerobic exercise increases linear growth and final height in girls with CPP.

Objectives To investigate the clinical significance of CYP2C19 genotype detection for antiplatelet therapy of elder cardiovascular and cerebrovascular diseases(CCVD).Methods We enrolled all elderly patients with either cardiovascular or cerebrovascular disorders who received clopidogrel as mono drug or in combination with another antiplatelet drug aspirin as secondary prevention for more than 12 months in our hospital from January to August 2015.Somatotypes of CYP2C19 genotypes of all participants were assessed to analyze the relapse of cardiac-cerebral vascular diseases in these patients.Results A total of 250 patients were enrolled,including 179 male and 71 female,with average age of (85.2 ± 7.9) years.Among these patients,there were 97 (38.8%) cases with EM CYP2C19 genotypes,110 cases(44.0 %) with IM CYP2C19 genotypes,43 cases(17.2 %) with PM CYP2C19 genotypes.When treated with clopidogrel for antiplatelet in secondary prevention process,the rate of the relapse in cardiovascular event was 34.9% and higher in PM CYP2C19 genotype than in EM and IM CYP2C19 genotype (19.6 % and 15.5 %,respectively) (x2 =7.251,P =0.027).This phenomenon was similar to patients who received stent implantation(x2=6.393,P =0.041).However,no statistically significant difference was observed in the recurrence rate of cerebral vascular disease between three different genotypes(EM 29.9 %,IM 20.0 %,PM 27.9%,x2 =2.880,P =0.237).Conclusions Our results highlight that CYP2C19 genotype might be a potential guidance for secondary prevention of cardiovascular and cercbrovascular disorders among elderly patients.Clopidogrel may be less effective in patients with SM CYP2C19 genotype than those with EM or PM CYP2C19 genotype for secondary prevention of cardiovascular disease.

Objective To evaluate left ventricular systolic synchronicity in patients with dilated cardiomyopathy by V-plane imaging and compare with clinical commonly used tissue Doppler imaging (TDI),evaluate the relevance and consistency between these two parameters.Methods 20 patients diagnosed with DCM and 20 healthy controls were enrolled,2D images,V-plane imaging and TDI waveform were acquired.Time to peak velocity of left ventricular 12 segments were measured by TDI and the standard deviation (TDI_SD) were calculated.Displacement time to peak were measured by V-plane and the standard deviation (V-plane_SD) were calculated.Results Compared with control group,TDI_SD and V-plane_SD increased significantly (P < 0.01),TDI time to peak increased and V-plane time to peak decreased significantly(P <0.01).In the two group,12 segment time to peak measured by V-plane were significantly higher than TDI(P < 0.01).There was a significant correlation between TDI_SD and V-plane_SD (r =0.925,P <0.001).Bland-Altman plot showed that 95% plots of ratio of TDI_SD and V-plane_SD were among limits of agreement,which was (0.50,1.36).Conclusions Left ventricular systolic synchronicity in DCM patients can be observed by V-plane imaging.V-plane has significant relevance and consistency with TDI,and can overcome the limitations of TDI that 12 segments can not be displayed in the same cardiac cycle.

0.05). Conclusions HF could not only relax cerebral vessels, reduce the CVR and enhance the CBF, but also dilate the femoral vessels of CVS dogs. Nevertheless, the latter action was much weaker. Furthermore, there was no relationship between effects of HF on vascular relaxation and contraction activity and the blood vessel endothelium.

Objective To investigate the qualitative diagnosis of salivary gland mass with contrastenhanced ultrasound(CEUS).Methods The CEUS manifestations in 78 cases with salivary gland mass were observed after intravenous bolus injection with contrast agent SonoVue and confirmed by histology.Results Among 78 salivary gland masses,there were 29 cases with pleomorphic adenomas (37.2%),19with Warthin's tumors (24.4 %),7 with basal cell adenomas (8.9 %),and 11 with the other benign masses (14.1%),12 with malignant tumors (15.4%).The intensity of contrast-enhanced masses,whether the enhanced mass margin was clear,whether the peripheral enhancement rim was complete and whether the mass was enlarged were the diagnostic criteria to differentiate the benign and malignant tumors.The accuracy,the sensitivity,specificity,positive predictive value and negative predictive value were 87.2%,95.2%,56.3%,89.4%,75.0% respectively,and the results also displayed positive likelihood ratio and negative likelihood ratio were 2.178,0.085 respectively.Although they presented with the highest incidence among benign tumors,their CEUS manifestations showed remarkable statistical differences when the pleomorphic adenoma was compared with Warthin' s tumor and basal cell adenoma respectively in enhancement intensity(P <0.01) while there were no statistical differences between Warthin's tumors and basal cell adenomas (P >0.05).Conclusions CEUS manifestations of salivary gland mass were helpful to the differential diagnosis of various salivary gland tumors.
