BACKGROUND:Embryo viability assessment is directly related to the selection of embryo transplantation and clinical outcome of assisted reproduction.
OBJECTIVE:To summarize the assessment methods for early embryonic development.
METHODS:The first author searched PubMed database for relevant articles published from January 1990 to
December 2013 using the keywords of“assisted reproductive technology, art;pre-implantation embryo;embryonic development viability;evaluation methods”in English. Final y, 63 articles were included in result analysis.
RESULTS AND CONCLUSION:In the embryo quality evaluation, the most widely used method is morphological evaluation method which is characterized as rapid, non-invasive, and simple. With the development of assisted reproductive technology, the morphological evaluation combined with time-lapse imaging analysis system has been recognized in embryo selection. Recently, targeted-metabolic analysis has been proposed as a useful tool for assessment of embryo development potential, involving pyruvate acid, glycometabolism, amino acid, and embryo-derived cytokines (soluble human leukocyte antigen G1, platelet-activating factor, etc.). Furthermore, the pre-implantation genetic screening method targeting gene and chromosome abnormality is expected to find more effective markers for evaluating embryo developmental potential.

OBJECTIVE: To explore the proliferation inhibition and apoptosis of polysaccharides extracts from polysaccharides extracts from Hedyotic diffusa (PEHD) on Human Nasopharyngeal Carcinoma (NPC)cell line CNE2 cells in vitro. METHOD: CNE2 cells treated with various concentrations of PEHD were detected by MTT assay at 24 h, 48 h, and 72 h. The apoptotic cells were analyzed by flow cytometry with Annexin V/PI staining. The expression levels of Bax, Bcl-2 and caspase-3 protein were examined by Western blotting method. RESULT: The growth of CNE2 cells were suppressed after treatment with PEHD (P < 0.05), MTT assay showed that the highest cell inhibition rate reached to 76.5%, the inhibition in the doses from 2 to 6 mg/ml showed dose-and-time-dependent. The percent of apoptosis in 4 and 6 mg/ml PEHD treatment groups for 48 h were 31.32%, 46.28%, respectively, and significantly higher than that in control groups, 4.86% (P < 0.01). After the cells being treated with PEHD for 48 h, the expression of Bax and caspase-3 protein increased, and the expression of Bcl-2 protein decreased gradually. CONCLUSION PEHD could inhibited the growth of CNE2 cells and was dose-and-time-dependent, the mechanism may involve induction of cell apoptosis, which was associated with the activation of Bax and caspase-3 protein and the down-regulation of Bcl-2 protein expression.

BACKGROUND: Bone morphogenetic protein (BMP) is a protein possesses potential activity, which can increase and enhance its activity when the bone issues are damaged, so it can be used to repair the bone defects when combined with carrier. However,there are few reports concerning it as gene therapy.OBJECTIVE: To construct recombinant retroviral vector expressing human BMP2 gene and to discuss its biological function in ostecblasts.METHODS: BMP2-specific primers were designed and synthesized according gene sequence of human BMP2 gene in Genbank, then BMP2 gena was amplified by Hifi PCR, which was recombined with cloning vector pDNR-CMV homologousiy into pDNR-CMV-BMP2 plasmid identified by BMP2 PCR and enzyme digestion of Sail and EcoRI as well as gene sequencing; recombinant plasmid pDNR-CMV-BMP2 and retroviral plasmid pLP-LNCX were recombined homologously in IoxP sites into pLP-LNCX-BMP2 plasmid transferred into packing cell line PT67 and the supernatant was collected to assay viral titre. Human osteoblast was infected with retrovirus, then the growth of cells were observed by MTT, and the expression of BMP2 protein was detected by Western blotting at 48 hours transfectionRESULTS AND CONCLUSION: Digestion, BMP2 PCR and gene sequencing of pDNR-CMV-BMP2 were coincided with expected. After transfected with plasmid pLP-LNCX-BMP2, PT67 cells could be screened with G418 only to get stably integrated in BMP2, of whose supemanant viral titra amounted to 5×10~8 pfu/mL. MTT assay showed that there had no evident difference in cellular inhibition between the normal and retrovirus groups at 72 hours after transfection (P ＞ 0.05); Western blotting showed that the BMP2 was strong expressed at 48 hours after transfection. It demonstrated that BMP2 gene was successful cloned and its retrovirus vector was constructed.
