Résumé
Objective To study the cholesterol nuclear-cytoplasmic interaction effect and position cholesterol traits QTL in mice.Methods Improving the nuclear-cytoplasmic interaction models and methods that have been constructed, and analyzing the public database of total cholesterol and lipoprotein data of F2 group that derived from DBA/2J ( D2) and CAST/EiJ ( CAST) mice.Results Six QTL that controlling total cholesterol, HDL and nonHDL were located in 4 linkage groups in the genome.In the models constructed in this study, we found a QTL has significant interaction with cytoplasmic background, which changes the previous results of data analysis, the genetic mouse cholesterol and lipoprotein components opened up new ideas.Conclusion Mouse cholesterol trait is the result of interaction of nuclear genes and cytoplasmic background.
Résumé
Objective To evaluate the diagnostic angiography and interventional therapy for the different acute massive hemorrhage of abdomen. Methods 80 cases of acute hemorrhage of abdomen and pelvis with clinical data of selective arteriography and endovascular interventional therapy were collected and analized retrospectively. Seldinger technique was adopted for selective visceral angiography via femoral approach with lipiodal, gelfoam and spring coils as the embolic materials. Results All bleeding sites in 80 cases could be confirmed and 68 cases of them were successfully embolized, 9 cases occurred with rehaemor- rhagia and 3 cases were ineffective. Conclusion Interventional therapy not only ascertain the bleeding site, but also stop bleeding. The effect is certainly positive.
