Objective To evaluate the effects of Pidomorph on serum immune cell level and T cell subsets in children with bronchial asthma.Methods 140 pediatric patients with bronchial asthma from January 2014 to October 2016 in our hospital were randomly divided into experimental group and control group according to the order of admission,70 cases in each groups.The control group was treated with conventional glucocorticoid drugs,and the experimental group was treated with pidotimod.The total effective rate of clinical treatment,the rate of rapid breathing in the flow rate,forced expiratory peak value,forced breathing vital capacity were compared between two groups three weeks after treatment,and the serum levels of immune cells(IgA,IgG,IgM)and T cell subsets(CD3+,CD4+,CD8+)were compared before and after treatment.Results The total effective rate was 92.86%(65/70)in the experimental group and 72.86%(51/70)in the control group,the total effective rate in the experimental group was significantly higher than that in the control group(P<0.05); Forced breathing speed in the speed,forced expiratory peak value,forced breathing vital capacity in the experimental group were better than the control group(P<0.05); After treatment,the levels of serum immune cells(IgA,IgG,IgM)in the experimental group were significantly higher than those in the control group(P<0.05); After treatment,the levels of T cell subsets(CD3+,CD4+,CD8+)in the experimental group were significantly higher than those in the control group(P<0.05).Conclusion Pidotimod is effective and safe in the treatment of bronchial asthma in children,it can effectively regulate T cell subsets and improve the immune function of children with asthma.

Objective To research the reversal effects of psoralen on multidrug resistant action and its influence on intracellular Ca2+ concentration in MCF-7/ADR cells and to explore its possible mechanisms of reversing multidrug resistance (MDR). Methods The inhibitory effects of psoralen on the viability of MCF-7/ADR cells were determined with MTT assay, intracellular adriamycin (ADR) concentration was assayed with HPLC and the intracellular Ca2+ concentrations in different incubative duration were detected with confocal microscope. Results Psoralen from 1 to 20 μmol/L reduced the value of IC50 of ADR in MCF-7/ADR cells, enhanced accumulation of ADR and influenced Ca2+ concentration with a negative correlation in different duration (24 h, 48 h and 96 h). Conclusion Psoralen can reverse MDR in MCF-7/ADR cells and its mechanism may be related to the increase of the intracellular accumulation of ADR by enhancing the intracellular Ca2+ concentration.

Objective To observe the effects of selfmade Lifeihuayu decotion in the treatment of patients with bronchial asthma.Methods 102 patients with bronchial asthma were randomly divided into the observation group and the control group,each group had 51 cases.The patients in the control group were treated with the conven-tional treatment,while the patients in the observation group were treated with the conventional treatment plus selfmade Lifeihuayu decotion.They were treated for 8 weeks.The patients of the two groups were determined with lung function and blood gas analysis, including forced expiratory volume in one second ( FEV1 ) , forced inspiratory vital capacity ( FVC) ,peak expiratory flow( PEF) ,pH value,the partial pressure of oxygen( PaO2 ) and carbon dioxide partial pres-sure(PaCO2).Results The total effective rate were 98.0% in the observation group and 90.2% in the control group,the total efficiency of the observation group was significantly higher(χ2 =5.78,P<0.05).After treatment,the FEV1,FVC and PEF of the patient's in the two groups were significantly increased(t=5.325,4.821,2.761,all P<0.05),and compared with the control group,the FEV1,FVC and PEF of patients in the observation group improved more significantly(t=2.068,2.771,3.013,all P<0.05).After treatment,the PaO2 of the patient's in the two groups were significantly higher,which more obviously increased in the observation group than those in the control group( t=2.925,P<0.05).After treatment,the PaCO2 of the patient's in the two groups were significantly decreased,PaCO2 in the observation group significantly decreased more than that in the control group(t=3.063,P<0.05).Conclusion Selfmade Lifeihuayu decotion in the treatment of patients with bronchial asthma has curative effect,and can signifi-cantly improve lung function and blood gas analysis of patients.

Objective: To study the effects of soluble vascular endothelial cell adhesion molecule-1(sVCAM-1) and soluble intercellular adhesion molecule-1 (sICAM-1) in recurrent oral ulceration (ROU). Methods: sVCAM-1 and sICAM-1 in oral menbrane tissue sampls were measured with an enzyme linked immunosorbent assay using sandwich technices in 45 patients with ROU and 40 nomal controls. Results: The expression level of sVCAM-1 in the oral membrane tissue samples of ROU patients was higher than that in the controls (P0.05). Both sVCAM-1 and sICAM-1 expression were not significantly different with the stages (ROU-active and ROU-free) of the lesion. Conclusion: sVCAM-1 might play a role in ROU.

Aim To investigate the in vitro vasorelax-ant effect of DL0805-0, a Rho kinase inhibitor, on iso-lated rat thoracic aorta and explore its underlying mechanism. Methods Tension was measured to eval-uate the vasorelaxant effect of DL0805-0 on rat endo-thelium-intact and endothelium-denuded thoracic aorta rings. Rho kinase inhibitor fasudil, nitric oxide syn-thase inhibitor Nω-nitro-L-arginine methyl ester ( L-NAME), guanylate cyclase inhibitor methylene blue, cyclooxygenase inhibitor indomethacin, calcium-activa-ted potassium channel blocker tetraethyl ammonium ( TEA ) , ATP-sensitive potassium channel blocker glibenclamide and voltage-dependent potassium chan-nel blocker 4-aminopyridine ( 4-AP ) were used to il-lustrate the mechanisms of vasorelaxant effect of DL0805-0 . Results DL0805-0 exerted vasorelaxation in a dose-dependent manner in KCl (60 mmol·L-1 ) or NE ( 0. 1 μmol · L-1 ) -induced contraction. DL0805-0-induced vasorelaxation was significantly re-duced by L-NAME. However, methylene blue and in-domethacin did not significantly affect vasorelaxation of DL0805-0. In endothelium-denuded rings, TEA re-markably attenuated the vasorelaxant effect of DL0805-0 , while glibenclamide and 4-AP did not affect vasore laxation of DL0805-0 significantly. DL0805-0 also re-duced NE-induced transient contraction and inhibited contraction induced by increasing extracellular calci-um. Conclusion These results suggest that DL0805-0 induces vasorelaxation through an endothelium-depend-ent pathway. The opening of calcium-activated K+channels and blocking of Ca2+ channels in vascular smooth muscle cells may be one of the mechanisms of DL0805-0-induced vasorelaxation.

Objective Use MRS technology to detect in vivo Glx concentration of Zelanian rabbits' muscle.Methods Tweenty Zelanian rabbits are collected,SS-PRESS sequence is applied to check their Signal Ratio of Glx/TCr.After deta collection,draw blood and do the biopsy of the FOV's muscle tissue immediately.Mensurate the rabbits' blood Crn concentration,Glx and TCr concentration in muscle.Research the correlation between the above factors,attempt using the MRS Glx/TCr Signal Ratio and blood Crn concentration to predict muscular Glx concentration.Results The correlation between MRS Glx/TCr Peak Ratio and muscular Glx/blood Crn concentration ratio is 0.681.A linear regression formula is obtained: The predict Value of Glx concentration in muscle(?mol/g muscle)= Glx/TCr Peak Ratio ? Crn concentration in blood(mg/dl)?28.754-0.631.Conclusion Using a linear regression formula to predict the muscular Glx concentration,the results can reflect the level of the true values without biopsy,though it's not accurate enough for quantitatively analysis.
