Objective To investigate the effects of c?myc promoter binding protein 1(MBP?1)gene on the proliferation of human Saos?2 osteo?sarcoma cells in vitro. Methods Saos?2 cells were divided into three groups:blank control group(untransfected cells),negative group(cells transfected with missense sequence)and experimental group(cells transfected with MBP?1 shRNA). Two MBP?1 shRNA sequences and one neg?ative control shRNA sequence were designed ,synthesized and cloned into pSIREN?retroQ plasma. Then the recombinant plasmids were construct?ed and transfected into human Saos?2 osteosarcoma cells by Lipofectamine 2000. The expressions of MBP?1 mRNA and protein in Saos?2 cells were detected by real?time PCR and Western blot ,respectively. The effects of altered expression of MBP?1 on cell proliferation were measured by CCK?8 cell proliferation assay. The expressions of cyclin D1 and cyclin E in Saos?2 were determined by Western blot. Results PCR and sequenc?ing results indicated that the recombinant plasmids pSIREN?retroQ was constructed. The relative expression level of MBP?1 mRNA in the MBP?1 siRNA transfection group was significantly decreased than that in blank control group(P<0.05). Compared with the blank control group,the ex?pression levels of MBP?1 protein in the experimental group also significantly decreased. The proliferation abilities of Saos?2 cells at 48,72,and 96 hours after MBP?1 siRNA transfection were significantly increased than those in the blank control group(P<0.05). Compared with the blank con?trol group,the expression levels of cyclin D1 and cyclin E protein in the experimental group also significantly increased(P<0.05). Conclusion Knockdown of the expression of MBP?1 gene promotes the proliferation of human Saos?2 osteosarcoma cells. MBP?1 gene may become the new tar?get of gene therapy for osteosarcoma.

It's been confirmed that acupuncture-moxibustion is effective in treating primary dysmenorrhea, and the efficacy is closely related to the intervention time. By summarizing the latest research progress on real-time intervention and pre-intervention of acupuncture-moxibustion in treating primary dysmenorrhea, this articlewas to discuss about the effect of intervention time on the efficacy in treating primary dysmenorrhea and thus to provide evidence to choose the optimal intervention time. It brought up that real-time intervention of acupuncture-moxibustion can produce a significant analgesic effect in treating primary dysmenorrhea, while pre-intervention of acupuncture-moxibustion presents its advantages in generally regulating the body function. Therefore, the treatment of primary dysmenorrhea should combine real-time intervention and pre-intervention of acupuncture-moxibustion to enhance the clinical efficacy.
