Objective To study effect of piracetam combine with hyperbaric oxygen in treatment of acute carbon monoxide poisoning patients with electrocardiogram and its effects on Lactate clearance.Methods 60 patients of acute carbon monoxide poisoning who received therapy from February 2011 to February 2016 in our hospital were selected as research objects.All accord with the diagnostic criteria of acute carbon monoxide poisoning.According to draw method,those patients were divided into the experimental group(n=30)and the control group(n=30).The two groups were given a large number of sustained oxygen,intracranial pressure,protect brain cells,promote blood circulation and improve microcirculation and other basic symptomatic treatment.The control group on the basis,was treated with hyperbaric oxygen,one times a day,a total of ten times.while the experimental group was treated with piracetam combine with hyperbaric oxygen,hyperbaric oxygen method with the control group,intravenous drip of Piracetam and Sodium Chloride Injection,each 100ml,two times a day,a total of treatment for ten days.Then abnormal ECG,creatine kinase isoenzymes(CK-MB),troponin(cTnl),lactate clearance,incidence of delayed encephalopathy,mortality,therapeutic effect of two groups were compared.Results ECG abnormal rate there was no difference between the two groups before treatment,after treatment,the abnormal rate of the experimental group was significantly lower than the control group [6.66(2/30)vs.33.33％(10/30)](P<0.05); CK-MB、cTnl、6h and 24h after treatment,Lactate clearance rate was significantly higher than control group[(15.80±2.03)％vs.(10.26±2.01)％,(20.75±3.12)％vs.(13.07±2.56)％](P<0.05);DEACMP rate and mortality was significantly lower than the control group[6.66％(2/30)vs.33.33％(10/30),3.33％(1/30)vs.30.00％(9/30)](P<0.05); The total effective rate was significantly higher than the control group[95.56％(28/30)vs.75.56％(22/30)](P<0.05).Conclusion Piracetam combine with hyperbaric oxygen is well for acute carbon monoxide poisoning,which can improve the clearance rate of lactic acid,improve hypoxia and myocardial injury,and reduce the abnormal ecg.

To screen the available tomato pollution-safe cultivar varieties and reduce the potential food safety risks in Cd-polluted areas, the differences of Cd accumulation in different tomato (Solanum lycopersicum) varieties in southern China were studied by soil culture and hydroponic experiments. Firstly, the high and low accumulation varieties were selected from 25 tomato varieties under 2.94 mg/kg Cd stress by soil culture test, and then the responses of high and low accumulation tomato varieties to Cd stress were determined by hydroponic experiments. The results of soil culture test show that under 2.94 mg/kg Cd stress, there were significant differences in plant height, total biomass and yield among 25 tomato cultivars, and the Cd contents of fruits of all 25 tomato cultivars exceeded the highest limit value (0.05 mg/kg) of CAC (Codex alimentarius commission). Through cluster analysis, 7, 4 and 14 varieties accumulating relatively high, medium, and low concentrations of Cd in the fruits were screened, among which the highest, the lowest, and the average Cd contents in the fruits were 3.06 mg/kg DW, 1.47 mg/kg DW, and 2.21 mg/kg DW, respectively. The results of hydroponic experiment show that under the same concentration of Cd stress, Qiantangxuri F1, a high Cd accumulating variety, absorbed Cd faster, accumulated more Cd, used shorter oxidative stress response time and had stronger tolerance to Cd than Zhefen 3053, a low Cd accumulating variety. The typical high and low Cd accumulating varieties can provide a reference for agricultural production in heavy metal polluted areas and the development of molecular-assisted breeding methods of PSC. At present, cultivating low Cd accumulating PSC varieties and dynamic monitoring of Cd contents in tomato fruits are feasible methods in medium and light Cd-polluted areas.
