Comprehensive Evaluation of the Anti-Inflammatory Activity of Ling-Zhi-8 (LZ-8) In Vitro and a Rheumatoid Arthritis Animal Model.

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
Rheumatoid arthritis (RA) is an inflammatory disease caused by an autoimmune reaction. Only immunomodulators or related medicines can decrease RA progression. Ling-Zhi-8 (LZ-8) is a small-molecule protein in Ganoderma lucidum that inhibits inflammation. This study aimed to investigate the anti-inflammatory function and immunomodulatory activity of LZ-8 in RA. Rat RA animal and cell models were used to examine the anti-inflammatory efficacy of LZ-8 in inhibiting arthritis. Experimental results indicated that LZ-8 inhibited the production of interleukin (IL)-6 and the over-expression of cyclooxygenase-2 in lipopolysaccharide-stimulated macrophages. This suppressive effect may be associated with the potential inhibitory effect of LZ-8 on the MyD88-mediated Jun N-terminal kinase-mitogen-activated protein kinase signaling pathway. Administration of lower doses (3.125 mg/kg) of LZ-8 injections for 9 days reduced inflammation and swelling in the soles of the feet in the RA animal model. The pathological lesion of the limb digits of rats in the LZ-8 lower doses (3.125 mg/kg) group was relatively milder than those of the medium- and high-dose groups. Comparing the histological lesions, the LZ-8 high-dose group showed reduced synovial hyperplasia, and all three doses of LZ-8 mitigated damage to the articular cartilage.
