Needle-Knife Therapy Relieves Inflammation and Neuronal Apoptosis in Cervical Spondylotic Radiculopathy via IRE1α-XBP1 Signaling.
Article in Global spine journal, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
Study DesignTranslational animal study.ObjectiveTo investigate the therapeutic effects of needle-knife therapy in cervical spondylotic radiculopathy (CSR) rat models. This study also aims to determine whether these effects are mediated via inositol-requiring enzyme 1 alpha (IRE1α)-X-box binding protein 1 (XBP1) axis.MethodsA CSR rat model was established via spinal canal insertion. The IRE1α activator IXA4 was administered to enhance IRE1α-XBP1 signaling activity. Motor function and pain sensitivity were evaluated using paw withdrawal mechanical threshold (PWMT), paw withdrawal thermal latency (PWTL), and gait scoring. Microglial activation was evaluated by immunofluorescence staining for ionized calcium-binding adapter molecule 1 (Iba1) and tumor necrosis factor-alpha (TNF-α). Neuronal apoptosis was assessed via TUNEL/NeuN double immunofluorescence, qRT-PCR, and Western blotting (WB). Key proteins in the IRE1α-XBP1 signaling were analyzed using WB.ResultsCSR rats exhibited spinal cord inflammation, neuronal apoptosis, and aberrant activation of the IRE1α-XBP1 pathway. Needle-knife therapy significantly mitigated spinal cord pathology. The treatment suppressed inflammatory cytokines, inhibited pro-inflammatory microglial activation, and inhibited activation of IRE1α-XBP1 signaling. Administration of IXA4 partially reversed these protective effects.ConclusionNeedle-knife therapy ameliorates inflammation and neuronal apoptosis in CSR. These effects are associated with downregulation of the IRE1α-XBP1 signaling.
