Objective To investigate the effects of different concentrations of propofol on the apoptosis in hippocampal neurons in neonatal rats in vitro.Methods Primary hippocampal neurons were prepared from newborn Sprague-Dawley rats (aged 7 days) and cultured for 7 days.The neurons were randomly divided into 7 groups (n =8 each):control group (group C),propofol 4,8 and 12 μg/ml groups (groups P1-3),and fat emulsion 4,8and 12 μg/ml groups (groups F1-3).The cells were cultured for 24 h in the culture medium containing propofol 4,8 and 12μg/ml in groups P1-3,respectively.The cells were cultured for 24 h in the culture medium containing fat emulsion 4,8 and 12 μg/ml in groups F1 3,respectively.The cell morphology was examined by microscopy after 24 h culture.The expression of caspase-3 (by immuno-histochemistry) and neuronal apoptosis were detected.The neuronal apoptosis rate was calculated.Results Compared with group C,the neuronal apoptosis rate and caspase3 expression were significantly increased in groups P1-3 (P ＜ 0.05 or 0.01).The neuronal apoptosis rat and caspase-3 expression were increased in a concentration-dependent manner in groups P1-3 (P ＜ 0.05).The neuronal apoptosis rate and caspase-3 expression were significantly lower in groups F1-3 than in groups P1-3 (P ＜ 0.05).There was no significant difference in the neuronal apoptosis rate and caspase-3 expression between groups F1-3 (P ＞ 0.05).The damage to neurons was induced in groups P1-3 and most severe in group P3.Conclusion Propofol can promote the apoptosis in hippocampal neurons in neonatal rats in vitro in a concentration-dependent manner.

Objective To investigate the organic pollutants in the contaminated water irrigation area soil and to study the lipid peroxidation effect of the pollutants on mouse. Methods The organic pollutants of the polluted irrigation soil and control soil were extracted using the supersonic oscillator. The ingredients of the organic pollutants were measured by the GC-MS spectrum. The 40 sanitary Kunming mice were randomly divided into five groups: the dimethylsulfoxide control group,low dose group of control soil,high dose group of control soil,low dose group of polluted soil,high dose group of polluted soil. The administered doses of the low and high dose groups were 25.5 g dry soil/kg body weight per day by oral for two weeks. The activities of T-SOD,GSH-Px and the content of MDA in serum of mice were determined. Results Phenanthrene,yrene,diphenyl,fluorene,naphthalene,dimethyl-naphthalene,2,3,6-trimethyl-naphthalene,anthracene,dimethyl-anthracene,1,4-dimethyl-anthracene,fluoranthene,4-methyl-pyrene,dibenzothiophen,4-methyl-dibenzofuran,dibenzofuran,butylated-hydroxytoluene,dodecane,neopentyl-cyclohexane,trimethyl-heptane,1,2-dimethyl-cyclohexanimine,butethal were detected in the polluted irrigation soil and their levels were 14.3,2.1,1.3,1.1,0.8,1.3,0.4,2.9,7.2,2.3,9.1,0.2,0.4,1.4,1.7,0.37,0.9,0.11,0.02,0.02 and 0.13 mg/kg respectively in the polluted irrigation soil. Trimethyl-heptane,dimethyl-heptane and 1,2-dimethyl-cyclohexanimine were detected,and their levels were all 0.01 mg/kg in control soil. Compared with the solvent of dimethylsulfoxide group,the activities of T-SOD and GSH-Px of the high dose group of control soil and two dose groups of polluted soil all decreased,the differences were all significant(P0.05). Conclusion The soil has been contaminated with organic pollutants in the investigated area and the soil extract may produce a certain effect on lipid peroxidation in mice.

Objective To learn the control status of iodine deficiency disorders in Baoji City of Shaanxi Province.Methods From 2009 to 2011,according to the National Iodized Salt Monitoring Program,the iodized salt was monitored,and thyroid was examined in 12 counties(areas) of Baoji City.According to rural and urban area stratification,60 children aged 8 to 10 were selected in each county(district),and their urine samples were collected for determination of iodine content.In 2011,per capita daily salt intake was surveyed by the three weighing method at children's home whose urine was collected.Chencang Area,Fufeng County and Taibai County,representatives of Baoji City different geomorphic features were selected for investigation of water iodine,and urinary iodine of pregnant and lactating women,and 15 people were selected in each county (district).Results From 2009-2011,in the 12 counties(areas) in Baoji City,the coverage rate of iodized salt was all 100.00％(3468/3468); the qualified rate of iodized salt and the consumption rate of qualified iodized salt were all ＞ 99.00％.Children's goiter rate was 3.41％(87/2548),3.06％(77/2520) and 3.33％(84/2520),and they were all less than that of the national standard (＜ 5％).Medians of urinary iodine of 8-10 years old children were 368.20,293.80 and 332.50 μg/L,respectively,and the ratios of urine iodine ≥300 μg/L were accounted for 66.42％ (797/1200),48.05％(692/1440) and 56.67％(816/1440),respectively.Median urinary iodine of pregnant women was 301.81 μg/L and lactating women was 329.79 μg/L.A total of 1116 households were investigated,the median of per capita daily salt intake was 8.9 g.Eighteen water samples were collected,range of water iodine value were 0.60-10.25 μg/L.Conclusions Iodine nutrition in general population of Baoji City is exceeded the optimum level,and the current iodized salt concentration has some down space,but fully consideration should be taken on iodine needs in different iodine deficiency areas and among different groups of people.
