Objective To explore the clinical significance of interleukin (IL)- 17 in nasopharyngeal secretions (NPS) and serum of wheezing children under 5 years old. Methods Fifty-three children with recurrent wheezing under 5 years old were divided into wheezing group Ⅰ (with atopic high risks,27 cases)and wheezing group Ⅱ (without atopic high risks, 26 cases) ;20 children without infectious diseases such as hernia and renal calculus were enrolled as control group. After collecting and dealing their NPS and serum,the levels of IL-17 were measured by double-antibody sandwich enzyme-linked immunosorbent assay (ELISA). Results The levels of IL-17 in serum and NPS in wheezing group Ⅰ [(1469.32 ± 978.30),(1473.70 ±974.35) ng/L],and wheezing group Ⅱ [(263.34 ± 131.80), (788.28±132.40) ng/L] were significantly higher than those in control group [(36.48 ± 2.00), (36.45 ± 5.00) ng/L] (P ＜ 0.01 ), and the levels of IL- 17 in wheezing group Ⅰ were higher than those in wheezing group Ⅱ (P ＜ 0.05 ); the expression of IL- 17 in NPS and serum had a positive correlation (r = 0.313,P ＜ 0.05). Conclusion The detections of IL-17 in NPS can be used as laboratory index to distinguish wheezing children who have a tendency to persistent wheezing, and early intervention and treatment should be given.

Objective To observe the effect of Yiqi Huoxue Recipe on the expression of TGF-?1 and ?-IFN in rats with radiation-induced lung injury in different radiation time, and discuss the prevention and curative effect of Yiqi Huoxue Recipe and its possible action mechanism. Methods One hundred and twenty Wistar rats were randomly allocated into irradiation group (n =30), irradiation with Yiqi Huoxue Recipe-treated group (n =30), irradiation with ambroxol-treated group (n =30) and normal control group (n =6). The former three groups were irradiated at right hemithorax with a dose of 30 Gy (5 Gy per week). Animals were followed for 26 weeks after the first irradiation. The levels of serum TGF-?1 and ?-IFN of 6 rats in each group were assayed by ELISA at the end of 4th, 6th, 8th, 12th and 26th week after the first irradiation. Results In Yiqi Huoxue Recipe-treated group, the levels of serum TGF-?1 were significantly lower from the 4th week than that of the irradiation group (P0.05). Conclusion Yiqi Huoxue Recipe can inhibit the excretion of TGF-?1 and promote the excretion of ?-IFN. It suggested that Yiqi Huoxue Recipe might play an important role in the prevention and curation of radiation-induced lung injury.

Objective:To explore the relationship among lottery buying behaviors,risk attitudes and lottery re-lated cognitive distortions,in order to propose suggestions about the intervention of problem lottery players and the healthy development of the lottery.Methods:Totally 228 lottery players (120 males,108 females;150 unmarried,78 married)sampled from Jinan were asked to fill out the Questionnaire of Lottery Buying Behavior (LBB),Domain Specific Risk-Taking Scale (DOSPERT)and Lottery Related Cognitive Distortions Scale (LRCD).Correlation a-nalysis and path analysis were used to analyze the data.Results:The scores of irrational behavior of LBB were posi-tively correlated with the DOSPERT total scores and its factor scores of recreation and gambling,and positively cor-related with the LRCD total scores and its factor scores except optimistic (r=0.17 -0.34,Ps<0.01 ).While the scores of rational behavior of LBB were negatively correlated with DOSPERT total scores and factor scores of rec-reation and gambling,and negatively correlated with LRCD total scores and its factor scores of illusion of control, illusory correlation,over optimistic and gamblers'fallacy (r=-0.18 --0.37,Ps<0.01 ).Path analysis showed that lottery related cognitive distortions had complete mediating effect between risk attitudes and irrational behaviorsof buying lotteries.Lottery related cognitive distortions partially mediate the relationship between risk attitudes and rational behaviors of buying lotteries.Conclusion:It suggests that the higher risk attitudes the lottery players hold, the greater cognitive distortions they will have,which in turn the irrational behaviors of buying lotteries might easily to have.

It is very difficult for stroke patients to complete the action of squatting-standing because their equilibrium function ability has been seriously declined. It was necessary, therefore, to do a deep research on the action of human squatting-standing and to set up an accurate model and simulation. In our modeling research, the movements of upper limbs and head was neglected, and a seven-segment model was developed to establish the coordinate system of human squatting-standing action. It calculated the knee joint moment and hip joint moment during squatting and standing by utilizing Lagrange method, and then simulated this mathematical model by utilizing Matlab. Geometric model of human squatting-standing was developed and simulated in ADAMS which proved that the established Lagrange model was reasonable. It would also provide significant theoretical references for further study and development of squatting-standing rehabilitation training equipment.
