The protective mechanism of Yisheng Injection against hepatic ischemia reperfusion injury in mice.
Article in World journal of gastroenterology, 2004. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
aimHepatic ischemia/reperfusion injury may cause acute inflammatory, significant organ damage or dysfunction, and remains an important problem for liver transplantation. Our previous in vivo and in vitro studies demonstrated that Yisheng injection (YS), a traditional Chinese medicine, had protective effect on ischemia/reperfusion injury. In this study, we examined whether YS had protective effect for hepatic ischemia/reperfusion injury and explored its protective mechanism.
methodsHepatic warm ischemia/reperfusion was induced in mice. YS at different doses (5, 10, 20 mg/kg) was injected intraperitoneally 24 h and 1 h before ischemia and a third dose was injected intravenously just before reperfusion. The hepatocellular injury, oxidative stress, neutrophil recruitment, proinflammatory mediators and adhesion molecules associated with hepatic ischemia/reperfusion injury were assayed by enzyme-linked immunosorbent assay (ELISA), immunohistochemical assay and reverse transcription polymerase chain reaction (RT-PCR).
resultsUndergoing 90 min of ischemia and 6 h of reperfusion caused dramatical injuries in mouse livers. Administration of YS at doses of 5, 10 and 20 mg/kg effectively reduced serum levels of alanine aminotransferase (ALT), aspartate aminotransferase (AST) and lactate dehydrogenase (LDH), from 3 670+/-463 U/L, 2 362+/-323 U/L and 12 752+/-1 455 U/L in I/R group to 1 172+/-257 U/L, 845+/-193 U/L and 2 866+/-427 U/L in YS (20 mg/kg) treated group, respectively (P<0.01). The liver myeloperoxidase (MPO) and malondialdehyde (MDA) contents were decreased from 1.1+/-0.2 (U/mg protein) and 9.1+/-0.7 (nmol/mg protein) in I/R group to 0.4+/-0.1 (U/mg protein) and 5.5+/-0.9 (nmol/mg protein) in YS (20 mg/kg) treated group, respectively (P<0.01). Moreover, the serum levels of tumor necrosis factor-alpha (TNF-alpha) were reduced from 55+/-9.9 (pg/mL) in I/R group to 16+/-4.2 (pg/mL) (P<0.01). Furthermore, the over-expressions of TNF-alpha and intercellular adhesion molecule-1 (ICAM-1) were suppressed by YS treatment in a dose-dependent manner.
conclusionYS attenuates hepatic warm ischemia/reperfusion injury by reducing oxidative stress and suppressing the over-expression of proinflammatory mediators and adhesion molecules.
