Objective: To investigate the expression of MDR1 and GFP in the human hematopoietic cells mediated by adeno-associated virus. Methods: The GFP gene was transferred into the human hematopoietic cells by AAV vectors and created strong visible fluorescence by purely molecular biological means. Using adeno-associated virus vectors, we have transferred human mdr-1 gene into human hematopoietic cells and investigated the drug resistence of human hematopoietic cells modified with mdr-1 gene. PCR analysis confirmed that mdrl cDNA had been successfully transferred into the human hematopoietic cells. An assay of MTT proved that the human hematopoietic cells modified by mdrl gene had resistance to colchicine. Results: It was about 30% of the hematopoietic cells that expressed the green fluorescent proteins. The resistance of hematopoietic cells was increased parently when the cells were infected by the crude virus stocks. Conclusion: It is conducted that the AAV vector could successfully transfer the foreign gene into the human hematopoietic cells. The cells modified with mdrl gene have increased the resistance to drugs.

Objective:To investigate the impact of adding human menopausal gonadotropin (hMG) for in vitro fertilization-embryo transfer pregnancy outcomes in a standard population of non-advanced age with normal ovarian reserve function using a long follicular phase protocol.Methods:Clinical data of 489 patients with normal ovarian reserve function, who were admitted from January 2018 to January 2020 in the Affiliated Hospital of Guizhou Medical University and underwent in vitro fertilization for the first time with the long follicular phase protocol in fresh cycles, were retrospectively analyzed. The patients were divided into three groups according to whether or not to add urine-derived hMG and the timing of addition: non-addition group (group A), medium-term hMG group (group B1), whole course hMG group (group B2); the laboratory parameters of each group were observed, and the effect of ovulation induction drugs and pregnancy outcomes were compared.Results:The ages of B1 and B2 groups were significantly higher than that of group A ( P=0.019 and P=0.011). The basal FSH level of group B2 was significantly higher than those of group A and group B1 ( P<0.01 and P=0.006), and the basal FSH/LH ratio of group B2 was significantly higher than that of group B1 ( P=0.009). Antral follicle counts of group A and group B1 were significantly higher than that of group B2 ( P=0.007 and P=0.017). The superior embryo rate of group B2 [(47±27)%] was significantly higher than that of group A ( P=0.017). The embryo implantation rate of group B1 was significantly lower than those of group A and group B2 ( P=0.043 and P<0.01). The clinical pregnancy rate of group B2 [76.7% (155/202)] was significantly higher than those of group A ( P=0.039) and group B1 ( P<0.01). The live-birth rate of group B2 [67.3% (136/202)] was significantly higher than those of group A ( P=0.017) and group B1 ( P=0.001). Conclusions:For non-advanced aged patients with normal ovarian reserve function, the long protocol of follicular phase is suitable for those with relatively low ovarian reserve function. Adding hMG in the whole course of ovulation induction after gonadotropin-releasing hormone agonist reduction could improve the pregnancy outcomes by improving the quality of embryos.

Objective To construct the eukaryotic expression vector harboring the fragment of Alia gene, and to investigate the effects of it on the signal of quorum sensing and virulence factors producted by Pseudomonas aeruginosa(Pa). Methods The plasmid pET-AiiA was cutted by Nhe Ⅰ and Xho Ⅰ , then the AiiA fragment was cloned into eukaryotic expression vector pEGFP-N2. After the plasmid was transfected into A549 cells, the protein was extracted and AiiA protein was found in it by Western blot. After the extrac- tion was admixed into the LB broth, from culture supernatant extracts of Pa, the N-acylhomoserine lactone (AHL) was detected by bioassay, and the expression of pyocyanin and elastase were assayed by RT-PCR and optical density. Results The fragment of AiiA gene was cutted and then cloned into pEGFP-N2. AiiA protein was found in the transfected cells. After admixed with the extract harboring AiiA protein, in Pa medium, the AHL was hydrolyzed, and the expression of pyocyanin and elastase were reduced. Conclusion The virulence factors synthesized by Pa were reduced by the AiiA protein expressed in eukaryotic cell.

BACKGROUND:Whether activating transcription factor 7 interacting protein(Atf7ip)is involved in the regulation in osteogenic differentiation is still controversial,and studying its impact on osteogenic differentiation and its specific mechanisms is of great significance. OBJECTIVE:To investigate the effect of Atf7ip on bone morphogenetic protein 2 promoting osteogenic differentiation of mouse embryonic osteoblast precursor cells(MC3T3-E1). METHODS:MC3T3-E1 cells cultured in vitro were divided into three groups:normal group,interference group(NC-siRNA group,Atf7ip-siRNA group),and high expression group(CMV-VC group and CMV-Atf7ip group),and were transfected for 24 hours,and then treated with 200 ng/mL bone morphogenetic protein 2 for 0,12,24,and 48 hours,respectively.qRT-PCR was used to detect the mRNA expression levels of Atf7ip,alkaline phosphatase,osteocalcin,type I collagen α1 in the cells of each group.Western blot assay was used to detect the protein expression of osteogenic differentiation markers Sp7 and Runx2,and the expression of Atf7ip binding molecule SETDB1,histone H3 and H3K9me3.Alkaline phosphatase activity was detected by alkaline phosphatase staining. RESULTS AND CONCLUSION:(1)With the increase of bone morphogenetic protein 2 treatment time,the protein and mRNA expression of Atf7ip decreased,while the protein expression of Sp7,Runx2 and the mRNA expression of osteocalcin and alkaline phosphatase increased significantly(P<0.05).There was no significant change in the protein expression of Atf7ip binding molecule SETDB1.(2)Compared with the NC-siRNA group,the protein expression of Sp7,Runx2 and the mRNA expression of osteocalcin and type I collagen α1 were significantly up-regulated(P<0.05),and alkaline phosphatase activity was significantly enhanced;and H3K9 methylation significantly decreased in the Atf7ip-siRNA group(P<0.05).(3)Compared with the CMV-VC group,the protein expression of Sp7 and Runx,as well as mRNA expression of osteocalcin,alkaline phosphatase,and type I collagen α1 was significantly downregulated(P<0.05),and the alkaline phosphatase activity was significantly reduced in the CMV-Atf7ip group,while the H3K9 methylation protein in the CMV-Atf7ip group was significantly upregulated compared to the control group(P<0.05).(4)In conclusion,Atf7ip expression was decreased during bone morphogenetic protein 2-induced osteogenic differentiation of MC3T3-E1,and osteogenic differentiation was significantly increased after knockdown of Atf7ip.Overexpression of Atf7ip significantly weakened osteogenic differentiation,indicating that Atf7ip is a negative regulatory factor of bone morphogenetic protein 2 promoting osteogenic differentiation of MC3T3-E1 cells.
