Ameliorating lipopolysaccharide induced acute lung injury with Lianhua Qingke: focus on pulmonary endothelial barrier protection.
Article in Journal of thoracic disease, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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: Acute lung injury (ALI)/acute respiratory distress syndrome (ARDS) has long posed challenges in clinical practice, lacking established preventive and therapeutic approaches. Lianhua Qingke (LHQK), a patented traditional Chinese medicine (TCM), has been found to have anti-inflammatory effects for ameliorating ALI/ARDS induced by lipopolysaccharide (LPS). This study aimed to investigate the effects and potential mechanisms of LHQK on endothelial protection in LPS-induced ALI/ARDS Methods: In the animal experiment, we induced an ALI/ARDS model by intratracheal injection of LPS (5 mg/mL). LHQK (3.7 g/kg/d for low dose and 7.4 g/kg/d for high dose) or dexamethasone (DEX) (5 mg/kg/d) was administered to mice 3 days prior to LPS treatment. In the Results: Compared to the LPS group, LHQK significantly improved lung function, mitigated lung pathological injuries, reduced inflammatory cells and inflammatory cytokines [tumor necrosis factor (TNF)-α, interleukin (IL)-1β, and IL-6] levels in BALF, and inhibited the expression of vascular cell adhesion molecule-1 (VCAM-1), attenuated LPS-induced pulmonary oedema and FITC-dextran permeability, and enhanced the expression of vascular endothelial-cadherin (VE-cadherin) and occludin. Conclusions: In summary, LHQK can mitigate LPS-induced inflammatory infiltration, pulmonary edema, and pulmonary vascular endothelial barrier dysfunction in the context of ALI/ARDS. This is achieved by decreasing the levels of VCAM-1, and increasing the expression levels of barrier-associated junctions, such as VE-cadherin and occludin. Consequently, LHQK exhibits promising therapeutic potential in preventing the progression of ALI/ARDS.
