Objective To analyze the status of multiple organ failure in patients with acute poisoning and to investigate the relationship between sequential organ failure assessment (SOFA) and prognosis. Method A retrospective review of 76 patients admitted to emergency intensive care unit in the First Affiliated Hospital of China Medical University for acute poisoning was carried out. Data about heart rate, blood pressure, blood oxygen saturation, blood gas analysis, rutine blood examination (WBC,platelet,albumin, ALT,total bilirubin, BUN,creatinine, CK, CK-MB, blood glucose), dosage of vascular active agents and mental status were documented at admission and 48 h after admission. SOFAs were counted at admission (SOFA ) and 48 h after admission (SOFA ) and then a comparison was made between survivors and victims. Results There was no significant difference in SOFA between survivors and victims ( P = 0.26) , but significant difference in SOFA48 as well as SOFA was shown between survivors and victims (P < 0.01). Multivariate logistic regression analysis indicated that the SOFA48 of renal and nervous systems were the independent predictors with acute poisoning (P = 0.003 and 0.012 respectively). Spearman correlation analysis implicated that ALT,CK-MB, WBC,base excess (BE) and blood glucose (BG) had correlation with SOFAs48. Conclusions SOFA shows its score eorrellated with the prognosis of poisoning with a-cute poisoning and it is a practical method in eveluating the outcome of patients with acute poisoning.

Objective To investigate the effects ofTianqi-Yizhi granules on oxidative stress in the brain tissue, and learning and memory in Alzheimer's disease model rats.Methods A total of 90 male SD rats were randomly divided into 6 groups by random number table method: sham operation group, model group, huperzine A group and groups of low-, medium- and high-doseTianqi-Yizhi granules, with 15 rats in each group. The AD rat model was prepared by the left lateral ventricle injection of amyloid-β1-42. One week after modeling, the rats in the groups of low-, medium- and high-doseTianqi-Yizhi granules received intragastric administration of 0.8, 1.6 and 3.2 g/kgTianqi-Yizhi granules, respectively; the rats in the huperzine A group received intragastric administration of 0.02 mg/kg huperzine A solution; and the rats in the sham operation and model groups received intragastric administration of equivalent volume of normal saline for 30 days. Learning and memory were evaluated using the dark avoidance test. The activities of superoxide dismutase (SOD) and glutathione peroxidase (GSH-Px), and malonaldehyde (MDA) level in the brain tissue were determined. ResultsIn comparison with the model group, the latencies to step into the dark chamber in the high- and medium-dose Tianqi-Yizhi granules groups were significantly longer (239.05 ± 48.42 s, 214.35 ± 74.52 svs. 97.39 ± 30.69 s; allP<0.01), the numbers of errors significantly decreased (1.93 ± 3.25, 2.27 ± 3.09vs. 6.62 ± 3.45; allP<0.05), the activities of SOD (177.27 ± 63.10 U/mg, 164.53 ± 72.58 U/mgvs.72.56±21.04 U/mg; all P<0.01) and GSH-Px (2 899.36 ± 362.27 U/g, 2 407.68 ± 472.14 U/gvs. 1 397.64 ± 442.17 U/g; allP<0.01), and MDA level (24.75 ± 9.94 nmol/mg, 27.74 ± 5.82 nmol/mgvs. 37.56 ± 17.23 nmol/mg; allP<0.01) in the brain tissue significantly increased. ConclusionTianqi-Yizhi granules could attenuate oxidative stress in the brain tissue, and improve learning and memory in AD rats.

Objective To investigate the action mechanism of Tianqi Yizhi Granules for Alzheimer disease. Methods Ninety SD rats were divided into sham-operation group, model group, positive medicine group, high, medium and low dosage of Tianqi Yizhi Granules groups. SD rats were injected with aggregated amyloid β1-42 protein (Aβ1-42) into their left ventricle to establish AD models. Treatment groups received gavage with Huperzine A or Tianqi Yizhi Granules. The sham-operation group and model group received gavage with the same volume of normal saline.
