  • Research on Regulation Function ofγ-Secretase Inhibitor DAPT on the Differentiation of Neural Precursor Cell Line

    This study aims to investigate the effect ofγ-Secretase Inhibitor DAPT, (N-[N-(3, 5-Difluorophenacetyl)-L-alanyl]-S-phenylglycine t-butyl ester), on the differentiation of neural precursor cells and the production of neurons in the neural precursor cell line GE6. GE6 was cultured in medium with 4μmol/L DAPT added as the experimental group and the untreated medium separately as the control group. After 4 days of differentiation, we carried out the following experiments. We used immuno-fluorescent staining to observe the ratio of Tuj1, GFAP and O4 positive cells. We also used qRT-PCR to detect the effect of the DAPT on Tuj1 and GFAP mRNA transcription in the GE6. The results of immuno-fluorescent staining indicated that the Tuj1 ratio of experimental group was higher compared to that of the control group, but the GFAP and O4 ratio of experimental group was lower than that of the control group. The differences were statistically significant (P < 0.05). The result of qRT-PCR was in accordance with immunofluorescent staining results. It was well concluded that DAPT could promote the neurogenic differentiation of neural precursor cell line rather than leading to gliogenic differentiation. More neurons could be obtained for transplantation with the addition of DAPT.

  • Current situation and research prospects of adaptation guidelines

    ObjectiveTo analyze the current situation of adaptation guidelines. MethodsCBM, CNKI, VIP, WanFang Data, PubMed, EMbase, GIN, SIGN, NICE and AHRQ databases were electronically searched to collect studies related to adaptation guidelines from inception to August 31th, 2020. Two reviewers independently screened literature, extracted data, and assessed the risk of bias of included studies. Descriptive analysis was then conducted on the general situation of the adaptation guidelines. ResultsA total of 83 studies were included, involving 63 full-text studies, 16 methodological studies and 4 secondary studies. The quantity of published articles of the adapted guidelines had an overall upward trend, and 48.39% of the adapted guidelines were published in UK-hosted journals. 51.81% of the adapted guidelines reported receiving funding or project funding during the development process, and 67.46% reported information of conflict of interests. Among the 33 adaptation guidelines published in the past five years, 33.34% reported their methodology used ADAPTE, 6.1% reported their methodology used GRADE-Adolopment, and 60.56% did not report the adaptation method. ConclusionsAt present, the international research on the adapted guideline is extensive, however, it is still in its infancy in China. The adaptation guideline is also required to be based on a theoretical framework, standardize the development of methodology, and ensure the quality of the adaptation guideline.
