Objective To observe the effect of asarone injection on terms of airway inflammation factor in asthmatic children.(Metho)ds Sixty asthmatic children were chosen and divided randomly into methotrexate group and control group.In the methotrexate group,intravenous injection with 2 times per day was given.The concentration of the injection solution was 0.01%,which was mixed by(0.5 mg/kg) asarone injection and 10% glucose injection.In control group,intravenous injection once per day was given.The solution consisted of 4-6 mg/kg aminophyline injection and 100 mL 5% glucose injection.Every 7 continuous days was taken as one process stage.Two process stages were observed during the experiments.Results After two weeks,the eosinophils and the macrophage were changed significantly(P

Objective To investigate the effect of celecoxib on endometrial carcinoma cell HEC-1-B and expression of the COX-2 mRNA.Methods To investigate the inhibition of different concentration Cele- coxib on the growth of human endometrial carcinoma cell HEC-1-B by the method of cell culture and MTT experiments.Detect the changes of expression of the COX-2 mRNA by RT-PCR.Results Celecoxib could effectively inhibit the growth of the HEC-1-B cell in dose and time dependent manner.Celecoxib could inhib- it the expression of the COX-2 mRNA.The inhibition ratio of expression in COX-2 mRNA of 20?mol/L and 50?mol/L Celecoxib is 25.92 % and 50.81% respectively.Conclusion Celecoxib may inhibit the growth of endometrial carcinoma cell by degrading the expression of the COX-2 mRNA.

Aiming at motion artifacts and off-resonance artifacts in multi-shot diffusion magnetic resonance imaging (MRI), we proposed a joint correction method in this paper to correct the two kinds of artifacts simultaneously without additional acquisition of navigation data and field map. We utilized the proposed method using multi-shot variable density spiral sequence to acquire MRI data and used auto-focusing technique for image deblurring. We also used direct method or iterative method to correct motion induced phase errors in the process of deblurring. In vivo MRI experiments demonstrated that the proposed method could effectively suppress motion artifacts and off-resonance artifacts and achieve images with fine structures. In addition, the scan time was not increased in applying the proposed method.

The paper analyzes the current situation of domestic second-tier hospitals from such perspectives as the allocation of nursing human resources, professional titles, the time needed to complete nursing tasks, and the actual number of nurse hours. It puts forward suggestions on the appropriate size and work load of the nursing force in domestic second-tier hospitals in the hope of providing empirical basis for revising the size of the nursing force in such hospitals.
