Objective To observe the changes of femur biomechanical properties in fluorosis rats. Methods Fifty Wistar rats of thirty-day old, weighing 90-100 g, were randomly divided according to body mass into fluorosis and control group of 25 each. Fluorosis group drank tap water containing 100 mg/L of fluoride, the control group drank tap water. The rats were observed of dental growing status and killed after feeding 6 months. Their femurs underwent tensile strength, impact, shear, bending experiments. Results The deteetable rate of dental fluorosis was significantly higher in fluorosis group[92%(23/25)] than control group[0(0/25),X2=38.97, P<0.01]. Biomeehanical data in fluorosis group(225.67±11.81,1.94±0.15,76.62±6.10,39.96.3±3.90) were lower than those of the control group(244.70±13.38,2.39±0.19,87.72±7.05,45.75±3.75) in experiments of tensile strength (MPa), impact toughness (J/mm2), shear and bending strength (MPa). The difference was statistically significant(t=3.372,5.879,3.756 and 3383, respectively, P<0.01) between the two groups. Conclusion Fluorides affected bone metabolism in rats, femur biomechanieal properties ehanged in fluorosis rats.

Purpose To test the virus inactivation effect of water bath method at 60 ℃ for 10 hours and alcohol treatment for 3 hours which was used in the production of urinary trypsin inhibitor(UTI).Methods Sindbis virus,Pseudorabies virus(PRV) and poliovirus1(PV1) were used as indicated viruses in this test.After being added separately into the UTI raw material in 10% proportion,the viruses were treated with water bath at 60 ℃ for 10 hours and alcohol for 3 hours and then the samples of UTI were taken to inoculate the cell line for assay of cytopathic effect.Results The water bath at 60 ℃ for 10 hours could inactive Sindbis,PRV and PV1 in more than(6.503±0.102)LgTCID_(50),(6.42±0.158) LgTCID_(50) and(6.587±0.061)LgTCID_(50) respectively,and alcohol treatment for 3 hours could inactive Sindbis,PRV and PV1 in more than(5.88±0.204)LgTCID_(50),(6.378±0.268)LgTCID_(50) and(5.963±0.118) LgTCID_(50) respectively.No cytopathic effect was found in the cell line which was inoculated with treated samples after blind passage for three generations.Conclusion The water bath method at 60 ℃ for 10 hours and alcohol treatment for 3 hours which were used in the production of UTI had good effects on virus inactivation and the inactivation efficiency on Sindbis,PRV and PV1 was more than 6 LgTCID_(50)/mL.

Objective To investigate the effects of resveratrol on cell growth,migration,and invasion of human breast cancer cell line MDAMB-231.Methods MTT assay and soft agar colony formation assay were used to detect the effects of resveratrol on cell growth.The effects of resveratrol on cell migration and invasion were determined by Transwell migration assay and Transwell invasion assay.respectively.Results Resveratrol(25 to 200 μmol/L)inhibited the growth of MDA-MB-231 cells in a time-and concentration-dependent manner(P＜0.01).The colony formation rate of MDA-MB-231 cells decreased with the increase in the concentrations of resveratrol.After being treated with resveratrol of 25,50,100 and 200 μmol/L for 24 hours,the invasive and migratory ability of MDA-MB-231 cells was significantly inhibited (P＜0.01).Conclusion Resveratrol could inhibit the growth of MDA-MB-231 cells,and the invasive and migratory ability of MDA-MB231 cells is also inhibited by resveratrol through degrading extracellular matrix.

Objective To investigate the possible damaging effect of infrasound on ultrastructure and permeability of rats′ blood retinal barrier (BRB). Methods Twenty mature male rats, averagely divided into 5 groups according to the exposure duration, were exposed to infrasound at a 16 Hz frequency and 130 dB sound pressure level in a pressure chamber for 2 hours per day. After exposed for 0, 1 day, 7, 14, and 21 days respectively, ultrastructural changes of rats′ BRB were observed through injection of lanthanum (La) nitrate solution, which was used as a tracer to demonstrate the breakdown of the BRB. Results With prolonging the duration of infrasound exposure, BRB structure lesion, chondriosome tumefaction, endoplasmic reticulum expandedness, membrane disc damage, retinal pigment epithelial cells distortion and putrescence, karyotheca expandedness, and La leakage on each level of retina aggravated gradually. Conclusion Infrasound may cause the breakdown of BRB, and the lesions aggravated with prolonged infrasound exposure time.

OBJECTIVETo establish osteoblast model, primary cilla model was removed by chloral hyrate, observe effects of osteoblast primary cilla moved on enhancing ALP staining and calcified nodules staining in electromagnetic field.

METHODSThree 3-day-old male SD rats weighed between 6 and 9 g were killed, cranial osteoblast was drawed and adherencing cultured respectively. Cells were subcultured and randomly divided into 4 groups until reach to fusion states. The four groups included chloral hydrate non-involved group (control group), 2 mM, 4 mM and 8 mM chloral hydrate group, and cultured in 37 °C, 5% CO2 incubator for 72 h. Morphology of primary cilla was observed by laser confocal scanning microscope, and incidence of osteoblast primary cilia was analyzed by Image-Pro Plus 6.0 software. Cells in the correct concentration group which can removed cillia most effectively were selected and divided into 3 groups, including control group (C), Electromagnetic fields group (EMFs), and EMFs with 4 mM chloral hydrate group. DMEM nutrient solution contained 10%FBS were added into three groups and cultured for 9 days and formation of ALP were observed by histochemical staining of alkaline phosphatase. After 12 days' cultivation, formation of mineralization nodes was observed by alizarin red staining.

RESULTSCompared with control group and 2mM chloral hydrate group,4 mM chloral hydrate group could effectively remove osteoblast primary cilla (P<0.01). Removal of osteoblast primary cilla could weaken the formation of ALP and mineralization nodes in osteoblast in EMFS. Compared with EMFs group, the area of ALP and mineralization nodes in EMFs with 4 mM chloral hydrate group were decreased obviously (P<0.01).

CONCLUSION4mM chloral hydrate could effectively remove osteoblast primary cilia. Primary cilla participate in EMFs promoting formation of ALP and mineralization nodes in osteoblast and provide new ideas for exploring mechanism of EMFs promoting osteoblast maturation and mineralization.
