Résumé
Aim To study the effect of salidroside on the proliferation, migration, invasion and apoptosis of human highly metastatic liver cancer cells ( 97 H cells) . Methods Multifunctional cell analyzer was used to determine the effect of salidroside on the proliferation of 97H cells. Scratch assay was used to determine the effect of salidroside on the migration ability of 97H cells. Transwell assay was used to determine the effect of salidroside on the invasion ability of 97 H cells. Inverted microscope was used to observe the effect of salidroside on the morphology of 97H cells. Transmission electron microscope was employed to observe the effect of salidroside on mitochondria in 97 H cells. Flow cytometry was used to analyze the effect of salidroside on apoptosis and cycle distribution of 97 H cells. q-PCR was used to determine the effect of salidroside on related apoptosis genes in 97H cells.Western blot was used to determine the effect of salidroside on related migration, invasion and apoptosis proteins in 97H cells. Results Compared to blank group, salidroside treatment inhibited the proliferation, migration and invasion of 97H cells, and induced apoptosis of 97H cells. Salidroside could up-regulate the relative expression of Caspase-3 (P <0.05). Salidroside could up-regulate the levels of E-cad, Bax, Caspase-3 and Caspase-9 proteins (P <0.05), and down-regulate the levels of N-cad, Girdin and Bcl-2 proteins (P < 0. 05 ). Conclusions Salidroside has inhibitory effects on the proliferation, migration and invasion of 97H cells, and induces apoptosis of 97H cells through mitochondrial pathway.

<p><b>OBJECTIVE</b>To investigate the HLA-A, B and DRB1 allele polymorphism of the Han race population in Lanzhou area.</p><p><b>METHODS</b>Polymerase chain reaction-sequence specific primer was used to detect HLA-A, B and DRB1 alleles in 200 unrelated healthy Han individuals from Lanzhou region, Northwest China, and the results were compared with those of Han populations in North, South and Northwest China, and Hui, Uigur and Tibetan population in China.</p><p><b>RESULTS</b>Fourteen of alleles were detected and identified for HLA-A; 32 for HLA-B; and 13 for HLA-DRB1. HLA- A*01, A*02,A*11,A*24, A*30, A*31, A*33; HLA- B*13, B*15, B*40, B*44, B*46, B*51, B*58, B*60; HLA- DRB1*04,. DRB1*07, DRB1*08, DRB1*09, DRB1*11, DRB1*12, DRB1*14 and DRB1*15 were the most common alleles. The frequencies of HLA-A, B and DRB1 genes of Lanzhou Han race were close to that of North China Hans and Hui population in Northwest China, and a little different to that of South China Hans. The HLA-DRB1 alleles were significantly different to those of Uigur and Tibetan race population of China.</p><p><b>CONCLUSION</b>The allelic polymorphism of HLA-A,B and DRB1 loci of Han race population in Lanzhou area was between North and South Han race of China, close to Northwest China Hui, and markedly different to Northwest China Uigur and Tibetan race populations.</p>
