Dipyrone & 2,5-dimethylcelecoxib suppress Th2-related chemokine production in monocyte.

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
BACKGROUND &
objectivesSelective cyclooxygenase-2 (COX-2) inhibitor is a form of thnon steroidal anti-inflammatory drug (NSAID) and is commonly used in autoimmune and rheumatic diseases to control inflammation and alleviate pain. Tumour necrosis factor-alpha (TNF-α) production and an imbalance of T helper 1 (Th1)/Th2 contribute to the pathogenesis of autoimmune and also anti-tumour activity. Dipyrone is a NSAID used to treat pain worldwide. The celecoxib analogue, 2,5-dimethylcelecoxib (DMC), lacks COX-2 inhibitory activity but exhibits anti-tumour properties. However, the effects and the mechanisms of dipyrone and 2,5-dimethylcelecoxib on tumour necrosis factor (TNF)-α and Th1- and Th2-related chemokines in monocytes remain poorly defined. This study was carried out to investigate the effects of dipyrone and 2,5-dimethylcelecoxib on the expression of Th1 (IP-10) and Th2 (I-309 and MDC) and TNF-α in human monocytes and the associated intracellular mechanism.
methodsTHP-1 cells and peripheral blood mononuclear cells (PBMCs) were pre-treated with dipyrone (10(-9)-10(-4) M) and 2,5-dimethylcelecoxib (10(-9)-10(-5) M) 2 h before lipopolysaccharide (LPS) stimulation. Cell supernatant was collected 24 h after LPS stimulation. TNF-α, I-309, MDC and IP-10 concentrations of cell supernatants were determined using ELISA. Intracellular signaling was evaluated by w0 estern blot.
resultsDipyrone and 2,5-dimethylcelecoxib downregulated LPS-induced Th2-related chemokine I-309 and macrophage derived chemokine (MDC) production. Only high dose of 2,5-dimethylcelecoxib (10(-5) M), but not dipyrone downregulated LPS-induced IP-10. Only very high dose of 2,5-dimethylcelecoxib had effect on LPS-induced TNF-α expression in PBMCs. Dipyrone and 2,5-dimethylcelecoxib suppressed LPS-induced p65 and JNK MAPK (C-Jun N-terminal kinase mitogen activated protein kinase). expression. INTERPRETATION &
conclusionsDipyrone and 2,5-dimethylcelecoxib downregulated LPS-induced Th2-related chemokine I-309 and MDC in THP-1 cells. The suppressive effect on Th2-related chemokine I-309 and MDC may involve the downregulation of LPS-induced JNK and p65 expression.
