Dian sanguis draconis improves pulmonary fibrosis by activating autophagy to regulate the PA/PAI-1 balance.

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
backgroundPulmonary fibrosis (PF) is a severe lung disease that manifests as lung tissue destruction and collagen deposition and easily leads to respiratory failure. It is difficult to reverse these conditions using current treatment methods. This study focused on the exploration and development of novel drugs for the treatment of PF.
methodsThis study simulated the pathological process of PF by using a bleomycin (BLM)-induced rat model and a TGF-β1-induced
resultsIn untreated PF rats, severely disordered lung tissue, thickened alveolar septa, and excessive deposition of collagen fibers were observed. In addition, the level of autophagy was inhibited, and the balance of PA/PAI-1 in the lung tissue was disrupted. After treatment with DSD, these pathological injuries improved, as demonstrated by the restoration of lung tissue structure, reduction in collagen fiber deposition, recovery of autophagy levels, and remodeling of the PA/PAI-1 balance. In addition, mechanistically, DSD improves PF by increasing the level of autophagy-related proteins and regulating the PA/PAI-1 balance.
conclusionThis study confirmed the significant effect of DSD in alleviating PF. These findings provide new drug candidates for the treatment of PF.
