A study has indicated the expression of Smad2 in human dental pulp cells, but there are no reports about the functions of Smad2/3 in TGF- P modulating dental pulp repair and tooth development.

本研究的目的是观察人牙髓细胞内Smad2和Smad3分子在TGF-β1信号转导中的作用，以及TGF-β1对二者表达水平的调控方式，并检测Smad2和Smad3在牙胚发育的不同时期和正常、龋坏、炎症牙髓组织中的表达及其变化，旨在从细胞内信号转导水平探讨TGF-β调节成牙本质细胞分化和牙本质形成的分子机理，为揭示牙胚发育和牙髓损伤修复过程中基因表达的调控机制提供一定的实验依据。

I found my teacher to have a treatment of 5 of my teeth, fees are more and cures less. In my opinion pulpitis causes the toothache because of no propitiation of my small pulp. That stimulated me and made me uncomfortable. I promise that if some day in the future people ask me for therapy of tooth, as a doctor, I will do my best to relieve pain.

上周找老师看了看牙，花销不少但是牙还是很痛，根据自己感觉好象是因为深龋没有安抚就直接充填导致牙髓激惹了，这样弄的自己的心情也很不舒服，感觉钱打水漂了，以后一定要当个好医生，否则患者会恨死你的，反正我现在就讨厌这样的不负责任，牙齿好痛不说明天还要返工重新看，白花了时间和金钱没有好结果，唉。

起初我只晓得布鲁克雷德丝是美国少男少女崇拜的偶像，后来回台湾，甚至去年在北京，居然也四处看见她的海报，才惊讶她的魅力之大。
