To evaluate the efficacy of Yupingfeng droppill and western medicine in treatment of allergic rhinitis, 76 patients from Beijing Shijitan hospital during April 2011 to May 2012 were selected and randomly divided into the treatment group (n = 44) and control group (n = 32). The treatment group was treated with Yupingfeng droppill and cetirizine tablets, the control group was treated with cetirizine tablets, the effect of the two groups was observed after 28 days, after treatment, the symptoms and inferior turbinate volume contrast of the two groups were better than before. The obvious effective rate and total effective rate were 84.09%, 95.45% and 46.87%, 56.25% in the treatment group and and control group. The differences in the obvious effective rate and total effective rate were statistically significant between two groups (P < 0.05), Yupingfeng droppill has the curative effect on allergic rhinitis, which is better than simple oral cetirizine tablets.

Objective To investigate flow patterns at carotid bifurcation in vivo by combining computational fluid dynamics(CFD)and MR angiography imaging.Methods Seven subjects underwent contrast-enhanced MR angiography of carotid artery in Siemens 3.0 T MR.Flow patterns of the carotid artery bifurcation were calculated and visualized by combining MR vascular imaging post-processing and CFD. Results The flow patterns of the carotid bifurcations in 7 subjects were varied with different phases of a cardiac cycle.The turbulent flow and back flow occurred at bifurcation and proximal of internal carotid artery (ICA)and external carotid artery(ECA),their occurrence and conformation were varied with different phase of a cardiac cycle.The turbulent flow and back flow faded out quickly when the blood flow to the distal of ICA and ECA.Conclusion CFD combined with MR angiography can be utilized to visualize the cyclical change of flow patterns of carotid bifurcation with different phases of a cardiac cycle.

Objective To investigate the diagnostic significance of endoscopic findings in Henoch-Schonlein purpura(HSP),especially when abdominal pain preceded the cutaneous lesions.Methods The clinical data and gastroscopic findings in 37 cases of children with HSP were studied and analysed retrospectively in order to detect the pathological changes in the stomach and duodenum mucosa.The biopsy was taken in the pathological changeing place,and the relationship between clinical and endoscopic findings was analyzed.Results Detection rate of the pathological changes in the stomach and duodenum mucosa was 62.2%,31.3% of which experienced only cutaneous lesions,100% of which presented the acute abdominal pain.Three patients were not checked up the pathological changes.Of them,1 had arthritis,2 had Henoch-Schonlein nephritis.Characteristically endoscopic findings in the stomach and duodenum mucosa were found.The endoscopic findings included anabrosis,hyperemia,edema and hemorrhage.Conclusions Detection rate of the pathological changes in the stomach and duodenum mucosa is higher.Endoscopy is very helpful to the early diagnosis of HSP in children,especially abdominal pain presented firstly.

Objective To comparison the effect of two different ways of sputum aspiration for food reflux in stroke patients with mechanical ventilation.Methods Experimental sputum aspiration method and conventional sputum aspiration method were applied in 26 stroke patients with mechanical ventilation to conduct the self-control study.Two different ways of sputum aspiration for food reflux were compared ( experimental sputum aspiration in odd numbered days VS routine sputum aspiration in even numbered days).Results There were significantly differences in food reflux rate with two ways: experimental sputum aspiration method was 7.0％,and another was 13.7％(x2 =11.24,P＜0.05).Conclusions Experimental sputum aspiration method applied in stroke patients with mechanical ventilation can reduce food reflux rate,thereby reduce the incidence of aspiration pneumonia and was beneficial for the rehabilitation of patients.

The theoretical basis of the alcohol precipitation process control was provided, the alcohol precipitation was optimized and the relationship equation was got. The monod glycoside, loganin and paeoniflorin were used as the evaluation indexes to determine the impact factors of alcohol precipitation techniques of Liuwei Dihuang decoction by the Plackett-Burman experimental design and the levels of non-significant factors were identified. Then, Box-Behnken response surface methodology was used to research and discuss the critical process parameters influence the effect of alcohol precipitation and draw interaction between key process parameters and the correlation equation with index components. Through the establishment and solving the quadratic regression model of composite score, the optimum preparation conditions of alcohol precipitation techniques of liuwei were as follows: stirring speed was 580 r x min(-1), standing time was 17 hours, alcohol concentration was 34%, the density of Liuwei Dihuang decoction was 1.13. The response surface methodology for optimized alcohol precipitation techniques of Liuwei Dihuang decoction is. reasonable and feasible.
