Objective To investigate the effects of the different concentration of mineral trioxide aggregate (MTA) on the proliferation and differentiation of dental pulp stem cells (DPSCs) from the young permanent teeth.Methods DPSCs were isolated from the young permanent teeth and cultured by tissue explant method.The expression of STRO-1 was detected by using immunofluorescence technology.DPSCs were cultured with different concentrations of MTA (0.02,0.20,2.00,20.00 g/L).Cell proliferation was detected by MTT array.Cells were cultured in the appropriate concentration of MTA for 4 weeks,and then stained by Alizarin red to detect their mineralized nodule formation capacity.The cells were cultured with the appropriate concentration of MTA and collected after 12,24,36,48 h.The mRNA expression of ALP,BSP,OC and DSP after the treatment of MTA were detected by quantitative PCR.Results DPSCs were positive for STRO-1.The capacity of 0.20 g/L MTA promoting the proliferation of DPSCs was stronger than other concentrations.After 4 weeks,the mineralized nodules of DPSCs were observed after alizarin red staining.The PCR showed that with increasing induction time,the expression levels of DSP and OC were up-regulated.But that of ALP and BSP was increased first and then decreased.Conclusions In this study,MTA can promote the proliferation of DPSCs at 0.02,0.20,2.00 g/L concentration.It can induce odontoblast differentiation effectively by 0.20 g/L MTA.

Recent studies have revealed that obease increases the risk of differentated thyroid carcino-ma (DTC);iodine increases the risk of papillary thyroid carcinoma wheras decreases the risk of follicular thy-roid carcinoma;vitamin D decreases the risk of DTC,but there are not enough evidences to prove that vitamin A,C and E can decrease the risk of DTC;alcohol may decrease the risk of DTC,but the mechanism is still un-known;xenobiotics increases the risk of DTC.It is essential for DTC prevention to clarify the protection and risk factors.

Objective To study the effect of rehabil it ation training on the expression of S-100, GFAP and Nestin in the cortex of cer ebrally infarcted rats. Methods Sixty Sprague-Dawle y rats were used. Experimental cerebral infarction was caused in all the rat s. 24 hours after the infarction, all the rats were randomly divided into 3 grou ps: a rehabilitation group, an immobiliaztion group and a control group. The rat s in the rehabilitation group were given balancing, grasping, rotating and walki ng exercises everyday, while those in the immobilization group were immobilized in cages. The rats in the control group was without any treatment. Immunohistoc hemical technique was used to detect the S-100, GFAP and Nestin expression at t he time points of 24 hours, 1, 2, 3 and 4 weeks after infarction, respectively. Results S-100, GFAP and Nestin expression were foun d around the infarcted cortex. The response increased as the extension of the su rviving time. The immunohistochemical reaction in rats in the rehabilitation gro up was stronger than that in the immobilization group. Conclusi on Rehabilitation training can activate astrocytes, which could impr ove the internal environment, protect the neurons and promote repairing of neuro n.

Objective The study evaluated the efficiency and safety of a short-acting full-dose fibfinolytic regimen to promote early infarct-related artery (IRA) patency during the inherent delay experienced by infarction patients referred for angioplasty as the principal recanalization modality. Method Accepted aspirin and heparin, 75 patients were treated by an intravenous bolus of 20 mg recombined tissue-type plasminogen activator (rt-PA), then followed by 80 mg over 30 minutes. Patients were to undergo angiography as soon as possible following study drug. If the IRA was occlude (TIMI flow grade 0 or 1),or was open but with ≥50% stenosis, immediate early PTCA at the same time. The end point included patency rates on catheterzation laboratory (cath Lab) arrival, technical results when PTCA was performed, complication rates, clinical adverse events rates and left ventricular (LV) function by treatment assignment in two weeks. Results Patency on Cath lab arrival was 88% with combination treatment group (26% Thrombolysis in myocardia infarction trial TIMI-2, 66%TIMI-3), and 36%with primary PTCA group (20%TIMI-2, 16%TIMI-3), (P

0.10). Conclusion: Donepezil is effective in treating the cognition of AD and some of the mixed dementia, but it has little effect on VD.
