ABSTRACT
Objective To observe the influence of serum containing Rhizoma Chuanxiong on the proliferation and differentiation of mouse embryos stem cells(ESCs).Methods Mouse ESCs were co-cultured with serum containing Rhizoma Chuanxiong.The proliferation of ESCs was detected by CCK-8 method.The expression level of specific gene beta-myosin heavy chain (β-MHC) in cardiac myoblasts was detected by reverse transcription-polymerase chain reaction (RT-PCR).Results Compared with the blank rat serum group and the blank fetal bovine serum group,the differences of activities of ESCs in serum containing Rhizoma Chuanxiong group were in significant(P ＞0.05) and the expression level of specific gene β-MHC in cardiac myoblasts was increased (P ＜ 0.05).Conclusion Serum containing Rhizoma Chuanxiong can promote the differentiation of ESCs into cardiac myoblasts.
ABSTRACT
Objective To explore the clinical effect by using of 654-2 to multigravidae.Methods Among 60 multigravidaes deliverying,30 were treated with 654-2 and oxytocin,the other 30 multigravidaes were treated with oxytocin only for control.The time of dilatation of the cervix,the rate of fetal distress and neonatal asphyxia,the rate of operative delivery and postpartum hemorrhage were observed.Results The time of dilatation of the cervix and the rate of operative delivery were shorter than the control.It was significantly different between the two groups(P0.05).Conclusion 654-2 can promote the first stage of the multigravidae.It can reduce the rate of operative delivery.It is safety by using of 654-2 to short the first stage to multigravidae.
