In general, osteoporosis is a disease of bone which is caused by an imbalance between osteoblastic bone formation and osteoclastic bone resorption. However, the recent research showed that the ability of bone marrow mesenchymal stem cells differentiates into adipocytes is greater than osteoblasts and it was thought to cause into osteoporosis, such as diabetes.

中文摘要骨质疏松症一般被认为是细胞的骨生成作用与破骨细胞的骨吸收作用失去平衡，然而近年来的研究指出骨头内的间质干细胞分化成造骨细胞的能力减弱或是间质干细胞分化成脂肪细胞的能力增强，这样的结果往往会导致骨质疏松症，如糖尿病状态。

Results The strongest photoinactivation effect occured in the HEP-2 cells co-cultured with 1 mmol/L ALA for 8 h. The killing activity of ALA-PDT to the HEP-2 cells was positively correlated with the power density of the irradiation (r=0.88, P＜0.05).Conclusions ALA-PDT can effectively kill the cultured HEP-2 cells in vitro. The optimal killing activity was related to the time and the power density of the laser irradiation.

In Wistar rats, latent period of a-wave in scotopic rod response after 1-week transplantation was shorten (P.05); and latent period of a-wave in scotopic rod response after 2-week transplantation was prolonged (P.05); while latent period of b-wave in scotopic maximum response after 1-week transplantation was shorten (P.05). In RCS rats, amplitude of a-wave in scotopic rod response and photopic response after 4-week transplantation was increased (PO.05); while latent period of a-wave in scotopic rod response after 4-week transplantation was shorten (PO.05).Conclusion 1. At the age of 3 months, photoreceptors of the RCS rat degenerated completely, which leaded to the reduction of amplitudes of a-wave and b-wave.

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。
