Methods The proliferation of MC3T3-E1 cells exposed to 10-9 -10-3 mol/L NaF alone, 50 ?mol/L NaF and 5 ?mol/L AlCl3 alone and in combination ,was measured by CCK-8, and the change of cell cycle was measured by flow cytometry after treatment with various concentrations of fluoride and aluminum. Results Fluoride alone did not promote osteoblast MC3T3-E1cells proliferation, higher concentration fluoride inhibited MC3T3-E1 cells proliferation. Fluoride and aluminum combined exposure (50 ?mol/L NaF +5 ?mol/L AlCl3) stimulated proliferation of MC3T3-E1 cells (P

This study was aimed to explore the influence of extreme environment changes on the lung immune function in rats. Artificial climate system was used to simulate six extreme weathers, which were the sudden temperature increase (ZS), sudden temperature drop (ZJ), continuous high temperature (CG), continuous low temperature (CD), high temperature and high humidity (GWGS), normal temperature and high humidity (CWGS). And then, the method of enzyme-linked immunosorbent assay (ELISA) was adopted to detect bronchoalveolar lavage fluid (BALF) and related immune substances in lung tissues. The results showed there was significant difference of ZJ on IL-10 (P<0.05). There were significant differences of CG, CD, GWGS, and CWGS on IL-6, INF-γ and sIgA (P<0.05). Contents of the GWGS group and CWGS group were higher than that of the CG group and CD group. There was very significant difference on IL-10 in the CD group (P<0.01). It was concluded that the extreme environment changes had different influence on body’s immune. And different intervention factors cause the body’s immune factors to response accordingly.

Objective To apply the health education intervention based on protection motivation theory in community female patients with stress urinary incontinence,in order to establish a health behavior and to control urinary incontinence.Methods 96 female patients with stress urinary incontinence were randomly divided into the control group and the experimental group by random number table method,the control group received routine health education,the experimental group received health education based on protection motivation theory.The ICI-Q-SF score,pelvic muscle exercise compliance scale score,urinary incontinence coping efficacy score were compared between the control group and the experimental group.Results The ICI-Q-SF score of the experimental group after the intervention was 5.43 ± 1.77,which was significant lower than that in the control group,7.96±2.98,t=4.88,P＜0.01.The urinary incontinence coping efficacy scores of experiment groups after the intervention was 17.63±1.85,which was higher than that in the control group,13.49±2.46,t=-9.09,P＜0.01.There were 29 cases accounted for 63.04％ with good compliance and 17 cases accounted for 36.96％ with poor compliance in experimental group after intervention,14 cases accounted for 31.11％ with good compliance and 31 cases accounted for 68.89％ with poor compliance in control group after intervention,the difference was statistically significant,x2=9.306,P＜0.05.Conclusions Health education based on protection motivation theory can promote the coping efficacy and health behavior of community female patients with stress urinary incontinence and can effectively control urinary incontinence symptom.

Objective To quantify the changes of tongue color with the development of the disease according to the characteristics of human vision.Methods Psychological scales of tongue color perception were obtained from thc psychophysical experiments.Polynomial regression and support vector regression (SVR) were used to establish the mathematical model between the physical values and the psychological scales of tongue color.Results The psychological scales exported from the model could correspond to the visual perception of tongue color change, and SVR has higher accuracy.Conclusions The psychological scale, can not only quantitatively evaluate the tongue color in the development of the disease, but also quantify the degree of disease, to assist the doctors for disease diagnosis and treatment.
