Qingfei Zhisou oral liquid alleviates fever-induced inflammation by regulating arachidonic acid and lysophospholipids metabolism and inhibiting hypothalamus transient receptor potential ion channels expression.

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 explore how Qingfei Zhisou oral liquid (, QFZS) adjusts body temperature bias and the interaction of inflammatory factors levels and metabolomic differences.
methodsDry yeast was subcutaneously injected at 10 mL/kg to establish the pyrexia model. We randomly divided 60 Sprague-Dawley rats into five groups: control, model, positive, low dose of QFZS and high dose of QFZS. Inflammatory proteins were evaluated by Western blotting and immunohistochemistry. For the examination of the endogenous metabolites, enzyme linked immunosorbent assay and ultra-high-performance liquid chromatography high-resolution mass spectrometry were employed.
resultsQFZS significantly reduced rats' body temperature within 6 h after dry yeast injection and reduced the secretion of the arginine vasopressin, cyclic adenosine monophosphate, prostaglandin E-2, tumor necrosis factor-α (TNF-α), interleukin-6 (IL-6), and interleukin-1β in serum. Meanwhile, we identified 41 metabolites between the model and QFZS groups, including arachidonic acid and lysophospholipids. QFZS restored normal arachidonic acid levels. Based on the differential metabolite enrichment analysis, QFZS's anti-inflammatory and anti-pyrexia effects might be related to the inflammatory pathway regulated by transient receptor potential. Additionally, QFZS treatment reduced transient receptor potential melastatin 2 ion channel expression and affected TNF-α, heat shock protein 70, and cyclooxygenase-2 expression in the hypothalamus.
conclusionQFZS exerts its regulatory effects on fever by regulating the metabolism of lysophospholipids and arachidonic acid and the regulation of inflammation
