1 · What the graph read from 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.

2 · The registry

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

purposeCatalpol is the main active component of Rehmannia glutinosa, which has a variety of pharmacological activities, including anti-inflammatory and anti-oxidative effects. This study investigates the feasibility of catalpol intranasal administration and its protective effect on acute cerebral ischemia in rats via anti-oxidative and anti-apoptotic mechanisms. PATIENTS AND

methodsThis study investigates the method of catalpol intranasal administration to evaluate the nasal mucosal toxicity, brain targeting and pharmacokinetics of catalpol. The protective effect of catalpol of intranasal administration on stroke-induced brain injury in rats and its mechanisms on oxidative stress pathway Nrf2/HO-1 and apoptosis were also investigated using middle cerebral artery occlusion (MCAO).

resultsThe results showed that catalpol intranasal administration was safe and feasible with no hemolysis, no bad effect on the maxillary ciliary movement of bullfrog. After intranasal administration, the brain targeting index (DTI) of catalpol was greater than 1, which indicated that catalpol had good brain targeting after intranasal administration. The bioavailability of catalpol administered intranasally was higher than that of in plasma. In MACO model, catalpol intranasal administration could significantly reduce cerebral infarction volume, neurological dysfunction and brain edema. In addition, catalpol intranasal administration can also reduce the brain cell's occurrence of apoptosis, promote the expression of Bcl-2 protein and inhibit the expression of Bax protein, reduce oxidative stress damage via up-regulating expression of Nrf2 and HO-1, increasing the activities of SOD and decreasing the activities of MDA.

conclusionCollectively, catalpol intranasal administration has good safety, stability and brain targeting. It can effectively protect the brain injury of the rat model of acute cerebral ischemia and provide the possibility of drug administration in the acute stage of cerebral ischemia, especially before entering the hospital.
