This research is to investigate three of suture lines how to affect the proliferation and cell cycle of lung adenocarcinoma cell A549 in vitro. Methods： Three of suture lines were respectively cultivated with lung adenocarcinoma cell A549, after of 72 hours, we detected absorptions of each group by MTT method in order to reflect the proliferation of lung adenocarcinoma cell A549, and also examined percentage of G1 period cells and S period cells of each group by flow cytometry. Results： Different of suture lines had different effects on the proliferation and cell cycle of lung adenocarcinoma cell A549 （P 〈 0.05）. The effect of absorbent suture line was the strongest on the proliferation and cell cycle of lung arlenecarcinoma cell A549, the effect of chorda serica chirurgicalis was medium, and the effect of slide wire was poor. Different length of each suture line had different effects on the proliferation and cell cycle of lung adenocarcinoma cell A549 （P 〈 0.05）, Conclusion： Three of suture line materials have different effects on the proliferation and cell cycle of lung adenocarcinoma cell A549, with dose-effect relationship.展开更多
The regional extent and spatial distribution of ultrahigh pressure metamorphic(UHPM) and high pressure metamorphic (HPM) rocks, and the geometrical relationships of various petrotectonic units in the Dabie-Sulu region...The regional extent and spatial distribution of ultrahigh pressure metamorphic(UHPM) and high pressure metamorphic (HPM) rocks, and the geometrical relationships of various petrotectonic units in the Dabie-Sulu region indicate that the Triassic collisional suture line between the Sino-Korean and Yangtze cratons is situated at the northern margin of the Dabie massif, that is,along the Balifan-Mozitan-Xiaotian fault in the Dabie region, and possibly is linked to the Wulian-Yantai fault in the Sulu region to tbe east. The suture line has been strongly modified duriug and subsequent to UHPM aud HPM events.展开更多
