Restorative effect of modified dioscorea pills on the structure of hippocampal neurovascular unit in an animal model of chronic cerebral hypoperfusion.
Article in Heliyon, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 papers, 1 of them a synthesis that pooled it.
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
introductionA considerable part of old people suffer from Chronic Cerebral Hypoperfusion (CCH) in their long lives but have no way to change. The Modified Dioscorea Pills (MDP), a Chinese compound herbal prescription, has good clinical efficacy for CCH related diseases such as Vascular Dementia, whereas, what happened and how MDP works in CCH need to be clarified. Here, we investigate the neural inflammation and gliosis, neuronal apoptosis and regeneration in an animal model of CCH and interfered with MDP to explore some mechanisms of this Chinese herbal medication.
methods40 rats were randomly divided into Sham operated Group, Model Group and MDP Group according to a Random Number Table. CCH models were made by the modified 2-VO (two vessels occlusion) operation. The intelligence of rats were measured by Morris Water Maze (MWM) test; H & E staining and transmission electron microscope (TEM) were applied to observe the pathological and ultrastructural changes in hippocampus; The expression of key genes including growth associated protein 43 (GAP-43) and vascular endothelial growth factor (VEGF) and key protein including Bax, Bcl-2, nuclear factor-κB (NF-κB p65), microtubule associated protein-2 (MAP-2), Oligodendrocyte transcription factor 2(Olig-2), glial fibrillary acidic protein (GFAP) of hippocampus were detected.
resultsCCH lead to learning and memorial impairment and MDP can partly restore them; Neural inflammation, Neuronal apoptosis and astrocyte hyperplasia were common in Model Group but they were partly reversed by MDP; The expressions of GAP-43mRAN and VEGF mRNA in Model Group were much higher than those in Sham operated Group, but they reached the highest in MDP Group (P < 0.01 or P < 0.05).
conclusionsThrough regulating the expressions of key genes and proteins, MDP partly restore the intrinsic structure of Neurovascular Unit (NVU) in hippocampus, which revealed one of its therapeutic mechanisms on CCH.
