Objective To study changes and meaning of serum IL -4,IL -10,IFN -gamma,TGF -beta 1 level in patients with delayed encephalopathy after carbon monoxide poisoning.Methods From January 2011 and June 2014 in our hospital,40 cases of DEACMP patients were selected as group A;the 40 patients with DEACMP was divided into 12 cases of mild cognitive dysfunction,mild cognitive dysfunction in 20 cases,8 cases of severe cognitive dysfunction.40 cases with acute carbon monoxide poisoning (ACMP)patients were selected as group B;40 cases of healthy subjects were selected as healthy controls.Serum interleukin 4 and interleukin 10(IL -4)(IL -10),interfer-on gamma (IFN -gamma),conversion,growth factor beta 1 (TGF -beta 1)content were tested.Results In Group A and group B serum IL -4 levels were lower than that of healthy controls (P <0.01),and serum levels of IL -10 in group B were higher than that in group A and healthy controls (P <0.01),serum level of IFN -gamma in group A and group B was higher than the healthy controls (P <0.01),and in group A IFN -gamma levels were higher than group B (P <0.01),while in group A serum TGF -beta 1 level was lower than B group and the control group (P <0.01),and in group B TGF -beta 1 level was higher than the control group (P <0.01);With cognitive impairment aggravating of DEACMP patients,IL -4,IL -10,TGF -beta 1 levels were on the decline,and IFN -gamma level was increasing (P <0.01).Conclusion DEACMP patients serum and cerebrospinal fluid of IL -4,IL -10,IFN -gam-ma,TGF -beta measures such as abnormal expression,showed that the onset of DEACMP may be related to neural immune injury.Serum IL -4,IL -10,IFN -gamma and TGF -beta of DEACMP patients exists abnormal expression Serum IL -4,IL -10,IFN -gamma and TGF -beta levels are also related to the degree of cognitive impairment of DEACMP patients.The onset and progress of DEACMP may be associated with neural immune injury.

Background Lipid metabolism in liver shows circadian-dependent profiles. The hepatotoxicity of environmental chemicals is dependent on circadian time. Objective To observe the effects of bisphenol A (BPA) exposure at different zeitgeber time (ZT) on hepatic and blood lipid metabolism and decipher the underlying mechanisms related to circadian rhythm in mice. Methods Thirty-five female C57BL/6J mice were sacrificed every 4 h in a light-dark cycle (12 h/12 h). The liver tissues were collected to describe the circadian profiles of hepatic Rev-erba, Bmal1, Clock, Srebp1c, and Chrebp mRNA expression levels within 24 h. Thirty female mice were divided into 6 groups by the timing (ZT3 represents the 3 h after light on, ZT15 represents the 3 h after light off) and dose (50 or 500 μg·kg⁻¹·d⁻¹) of BPA exposure to observe hepatotoxicity. Mice were gavaged with designed doses of BPA once per day for 4 weeks. Mice were maintained with ad libitum access to food and water and measured body weight weekly. After the experiment, mice were euthanatized and liver tissues were separated to determine the biochemical indicators of lipid metabolism and lipid metabolism- and circadian-related gene mRNA expressions. Results Hepatic Rev-erba, Bmal1, Clock, Srebp1c, and Chrebp mRNA expression levels were rhythmic during a 24 h period in mice. At ZT3 and ZT15, BPA did not alter body weight, plasma glucose, plasma total cholesterol, plasma low density lipoprotein cholesterol, and plasma triglycerides (P>0.05). The plasma high density lipoprotein cholesterol decreased in the 50 μg·kg⁻¹·d⁻¹ BPA group at ZT3 by 14.56% compared with the control group (P<0.05). The liver triglycerides increased in the 50 μg·kg⁻¹·d⁻¹ BPA group at ZT15 by 115.20% compared with the control group (P<0.05). BPA decreased Srebp1c mRNA expression level when dosing at ZT3 and increased Chrebp, Srebp1c, and Acc1 mRNA expression levels when dosing at ZT15 compared with the control group (P<0.05). BPA increased Bmal1 mRNA expression level and decreased Rev-erbα mRNA expression level at ZT3 exposure and decreased Bmal1 and increased Rev-erbα mRNA expression level at ZT15 exposure (P<0.05). Conclusion BPA exposure at light or dark period has different effects on hepatic lipid metabolism in mice. Hepatic lipid deposit appears when BPA is dosed at dark period. Rev-erbα-Bmal1 regulation circuits and the subsequent upregulation of Srebp1c and Chrebp and the target gene Acc1 may be involved.
