Effect of EphB4/EphrinB2 reverse signal on angiogenesis induced by Xuefu Zhuyu Capsule () containing serum in human microvascular endothelial cell 1.
Trial report in Chinese journal of integrative medicine, 2016. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
objectiveTo evaluate the effect of Xuefu Zhuyu Capsule ()-containing serum (XFZY-CS) on EphB4/ephrinB2 and its reverse signal in human microvascular endothelial cell-1 (HMEC-1).
methodsXFZY-CS and the blank control serum were collected. HMEC-1 cells were randomly assigned to 6 groups including the concentration 1.25%, 2.5%, and 5% XFZY-CS groups and their blank serum control ones. The angiogenesis effect of XFZY-CS was tested with an in vitro tube formation assay and the best condition of pro-angiogenesis was determined. The effect of XFZY-CS on EphB4/ephrinB2 and the reverse signal were determined by Western blot and real-time quantitative polymerase chain reaction, respectively; we also confifirmed the results through activating and inhibiting the reverse signal by EphB4/fc and pyrophosphatase/ phosphodiesterase2 (PP2).
resultsXFZY-CS promoted angiogenesis at the concentration of 2.5% corresponding serum after being cultured for 48 h, while inhibited angiogenesis at the concentration of 5% after culturing for 48 and 72 h. Under the 2.5% serum concentration, XFZY up-regulated the expression of EphB4-mRNA at 12 h (P<0.05), and down-regulates its expression at 24 h (P<0.01). Protein expression of EphB4 was apparently up-regulated at 12 h and down-regulated at 24 h. The phosphorylation of ephrinB2 increased at 9 h (P<0.05). In addition, 2.5% XFZY-CS played a similar role as the reverse signaling activator EphB4/Fc ranging from 0.5 to 5 μg/mL (P>0.05). XFZY-CS also reduced the inhibitive effect of PP2 in limited periods.
conclusionsEphB4/ephrinB2 was the upstream signal in the process of angiogenesis and its reverse signaling was responsible for XFZY's effect on promoting angiogenesis.
