1 · What the graph read from it

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.

2 · The registry

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

Excessive inflammation driven by macrophage phenotype imbalance is a key pathological barrier hindering neural repair after spinal cord injury (SCI). Here, methacryloyl gelatin hydrogel (GelMA) loaded with natural anti-inflammatory agent resveratrol (Res) was designed and synthesized. Scanning electron microscopy (SEM), x-ray diffraction (XRD), fourier-transform infrared spectroscopy (FT-IR), Ultraviolet (UV) and rheological characterization confirmed that Res-loaded GelMA hydrogel (Res@GelMA) was successfully synthesized. High-Performance Liquid Chromatography (HPLC) analysis demonstrated sustained Res release. CCK8 and cell adhesion experiments confirmed that Res@GelMA treatment did not affect the cell function of RAW264.7 and had good cell compatibility. Flow cytometry, Enzyme-Linked Immunosorbent Assay (ELISA) and western blot assays revealed that Res@GelMA treatment promoted RAW264.7 to M2 polarization, while reducing the levels of inflammatory factors (IL-1β, IL-6, TNF-α) and down-regulating the expression of IL-1R1/MyD88/TNFR1 inflammatory signaling proteins. Transcriptome sequencing combined with functional screening identified C-type lectin receptor Clec7a as a key target gene regulated by Res@GelMA. Importantly, knockdown of Clec7a and Res@GelMA were both anti-inflammatory, promoted M2 polarization, and blocked the activation of the TLR2/TLR4-p38 MAPK signaling axis. In the SCI mouse model, local implantation of Res@GelMA significantly improved tissue pathological damage and enhanced motor function recovery compared with free Res or blank GelMA. In addition, Res@GelMA achieved systemic anti-inflammation by downregulating the Clec7a-TLR-p38 pathway in the injured area and promoting M2 polarization. This study developed an anti-inflammatory hydrogel material that can regulate the phenotype of macrophages, laying a theoretical and technical foundation for the development of neural repair strategies targeting the inflammatory microenvironment.
