RÉSUMÉ
Abstract@#Children s oral health is related to many factors. Research on potential risk factors of children s oral health helps improve children s oral health. Based on the Anderson extended model, this review reviews the domestic and foreign literature on the factors affecting children s oral health, and finally concludes that children s oral health is related to exogenous variables, primary determinants of oral health, oral health behavior and other factors. Children s oral health can be improved by developing good oral habits, strengthening the health beliefs of parents and children, improving the oral health service system and developing oral insurance system.

<p><b>OBJECTIVE</b>To study the effect of puerarin on the expression of Hsp (heat shock protein) 70 in the rats with cerebral injury induced by acute local ischemia.</p><p><b>METHOD</b>Rat model of acute local cerebral ischemia was made by ligating middle cerebral artery. The Hsp70 expression in brain tissue was detected by SP method of immunohistochemistry.</p><p><b>RESULT</b>The expression of Hsp70 was significantly higher in puerarintreated rats than those in the rats with cerebral ischemia.</p><p><b>CONCLUSION</b>Puerarin can enhance the level of Hsp70 expression in the rats with cerebral injury induced by acute local ischemia.</p>

<p><b>OBJECTIVE</b>To study the protection of puerarin on the cerebral injury in the rats with acute local ischemia.</p><p><b>METHOD</b>Rat was evaluated model of acute local cerebral ischemia was made by ligating middle cerebral artery. The cerebral damage toxylin and eosin((HE).</p><p><b>RESULT</b>The number of died neurons were significantly less in puerarin-treated rats than in the rats with cerebral ischemia (P < 0. 05). Similarly, the cerebral edema were significantly attenuated in the puerarin-treated rats as compared with cerebrally ischemic rats.</p><p><b>CONCLUSION</b>Puerarin can prevent the neuron from damage induced by acute cerebral ischemia.</p>

<p><b>OBJECTIVE</b>To observe the effect of Puerarin Injection on the hemorheology in acute blood-stasis model rats.</p><p><b>METHOD</b>The acute blood-stasis model rats were made by being soaked in ice water afer being injected adrenaline hydrochloride injection in a major dose. The changes of viscosity of whole blood and plasma, blood yield stress, erythrocyte aggregation and the maximum rate of platelet aggregation in the acute blood-stasis model rats were measured with Auto-Viscometer, and then the influence of Puerarin Injection on the hemorheology in the model rats was investigated.</p><p><b>RESULT</b>The viscosity of whole blood and plasma, and blood yield stress in the acute blood-stasis model rats were significantly higher than those in the normal control group (P < 0.01, P < 0.05). Both the high dose and the low dose of Puerarin Injection could reduce the viscosity of whole blood and plasma, blood yield stress and the maximum rate of platelet aggregation in the acute blood-stasis model rats (P < 0.01, P < 0.05). The high dose could also reduce the erythrocyte aggregation and the deformed Index of red blood cell (P < 0.05).</p><p><b>CONCLUSION</b>Puerarin Injection can ameliorate the hemorheology in acute blood-stasis model rats, and it has a dose-response relationship.</p>
