Metric Options: CountsSelecting the 1-year or 3-year option will change the metrics count to percentiles, illustrating how an article or review compares to other articles or reviews within the selected time period in the same journal. Selecting the 1-year option compares the metrics against other articles/reviews that were also published in the same calendar year. Selecting the 3-year option compares the metrics against other articles/reviews that were also published in the same calendar year plus the two years prior.
Example: if you select the 1-year option for an article published in 2019 and a metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019. If you select the 3-year option for the same article published in 2019 and the metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019, 2018 and 2017.

Article Description
When the abnormality occurs in proliferation, differentiation and apoptosis of trophoblasts, the invasion ability of placental trophoblast is weakened, which is prone to trigger the occurrence of various pregnancy diseases such as repeated spontaneous abortion (RSA). Clinically, Astragalus and Codonopsis pilosula polysaccharides (APS and CPPS) are used for the treatment of unexplained recurrent spontaneous abortion (URSA). Therefore, we aimed to probe into the roles of APS and CPPS in biological behaviors of placental trophoblasts. The trophoblasts were treated with APS and CPPS, and transfected with miR-92a-1–5p mimic and CCR7 plasmid to explore the roles of APS and CPPS. Cell viability and apoptosis were determined by CCK-8 and flow cytometry, respectively. The levels of miRNA/mRNA and protein were measured by qRT-PCR and western blot, respectively. The interaction between miR-92a-1–5p and CCR7 was analyzed by TargetScan and dual-luciferase reporter assay. Invasion and migration rates were assessed by Transwell and wound healing assays, respectively. APS combined with CPPS enhanced viability, Bcl-2 expression, and migration and invasion capabilities, while suppressing apoptosis, and expressions of Bax, Bim and miR-92a-1–5p in trophoblasts. Nevertheless, miR-92a-1–5p mimic produced the inverse modulations in trophoblasts, and partially reversed the effects of APS and CPPS. Furthermore, overexpression of CCR7, the target of miR-92a-1–5p, partially offset the effect of miR-92a-1–5p mimic in trophoblasts. Astragalus combined with Codonopsis pilosula polysaccharides modulates the biological behaviors of trophoblasts via miR-92a-1–5p/CCR7 axis. The regulatory axis we studied will be helpful for the treatment of URSA in the future.
