Construction and Swelling Properties of Thermosensitive N-isopropyl Acrylamide Microspheres With Controllable Size.

In recent years, thermosensitive poly(N-isopropylacrylamide) (PNIPAM) microspheres have received extensive attention due to their many advantages, and their size and swelling ratio are two crucial factors. In this paper, homogeneous and hollow thermosensitive microspheres were prepared by free radical polymerization in an aqueous solution. The effects of the process parameters on the size of the microspheres were studied.

[Effects of curcumin on TNF-alpha and TGF-beta1 in serum and lung tissue of SiO2-induced fibrosis in mice].

Aim: To study the effects of curcumin on TNF-alpha and TGF-beta1 in serum and lung tissue of SiO2-induced fibrosis in mice.

Methods: 75 mice were divided into five groups. After treated with curcumin 6 and 9 mice of each group were sacrificed on day 14 and 42 respectively to take their blood and lung tissue.

[Expression of tissue factor induced by IL-6 in HUVEC].

Objective: To investigate the effects of IL-6 at the expression of tissue factor (TF) in human vein endothelial cells(HUVECs).

Methods: HUVECs were incubated with IL-6 at the concentration of 0.5 ng/mL.
