Objective To investigate the different concentrations of progesterone on the expression of a disintegrin and metalloprotease 10 (ADAM10),long form leptin receptor (Ob-R) and the secretion of soluble leptin receptor (SLR),leptin (LEP) in primary pregnancy human chorionic trophoblast cells. Methods Cultured primary human trophoblast cells and added in different concentrations of progesterone (0,100,150 and 200 ng/mL) for 24 hours. The relative expression of ADAM10 and Ob-R in the cells and the content of SLR and LEP in the supernatant were detected. Results With increasing concentrations of progesterone,early human trophoblast cells ADAM10 content gradual-ly decreased,the difference between the two groups was significant (P<0. 05). With increasing concentrations of progesterone,human chori-onic trophoblast cells in early pregnancy Ob-R expression levels increased, the difference was no statistically significant between each two groups (P>0. 05). SLR content of the cell supernatants as the concentration of progesterone increased and decreased,there are significant differences between each two groups (P>0. 05). LEP cell supernatant in each group with the increase of the concentration of progesterone concentration increased gradually between the two groups were significantly different(P>0. 05). Pearson’s test showed that the expression of expression SLR and LEP exists a significant negative correlation (R= -0. 949,P<0. 01). Conclusion Progesterone may influence the ex-pression of ADAM10,SLR and LEP by the regulation of leptin to participate GDM occurs.

Objective To analyze the expression of dystrophin associated glycoprotein complex (DGC) in Duchnne muscular dystrophy (DMD) in different age groups. Methods The confirmed 24 DMD patients were divided into 3 groups according to their chronological age (children whose age between 1 to 3 were assigned to early childhood group; children whose age between 3 to 6 were assigned to preschool group; children whose age between 6 to 13 were assigned to school-age group). Several proteins from sarcolemmal muscle membrane were analyzed by immunohistocbemistry. Results The primary loss of dystrophin may lead to a secondary or completely deficiency of α-SG, β-SG, γ-SG,δ-SG, β-DG and dysferlin from sarcolemmal muscle membrane in different age groups. The expression of nNOS is completely deficient in the 3 groups, while the expression of caveolin-3 increased. Conclusions The expression of dystrophin related DGC proteins from DMD patients in different age groups showed diversed degrees of deficiency or complete deficiency. The deficiency of these proteins may occur during the embryonic period, while the increased expression of eaveolin-3 may have a relation with the regeneration of skeletal muscle fibers.
