Objective To analyze the whole genomic DNA methylation level and estrogen receptor α (ERα) gene promoter methylation status in systemic lupus erythematosus (SLE) with atherosclerosis (AS) in model mouse,and to explore its role in the pathogenesis of SLE with AS.Methods Eleven apoE-/-C57BL/6 mice were randomly divided into the model group (SLE+AS group) and the control group (AS group).Eleven wild C57BL/6 mice were also randomly divided into the model group (SLE group) and the control group (blank group).Single intraperitoneal injection of pristane 0.5 ml for the model group,single intraperitoneal injection of normal saline 0.5 ml for the control group.Eight months after injection,all mice were sacrificed,genomic DNA was extracted from spleen.The total genomic DNA methylation level was detected,and pyrosequencing was performed to determine the methylation status of ERα gene promoter.The differences between groups were compared.ANOVA,LSD-t test,Tamhane's T2 test were used for statistical analysis.Results The total genomic DNA methylation levels were (4.7±1.5)％,(5.1±0.5)％,(6.6±1.6)％,(7.5±1.6)％ respectively in the SLE+AS group,AS group,SLE group,blank group respectively,the average methylation indices of ERα gene promoter were (13.0±3.1)％,(26.7±7.2)％,(15.7±3.8)％ and (21.4±4.2)％ respectively.The total genomic DNA methylation level and the average methylation index of ERα gene promoter in the SLE+AS group and the SLE group was significantly lower than that of the blank group (P＜0.05).Compared with the AS group,the total genomic DNA methylation levels and the average methylation index of ERα gene promoter in the SLE+AS group were significantly decreased (P＜0.05).Conclusion The total genomic DNAs and the ERα gene promoters in SLE with AS model mouse are in low-methylation status.The results of this study suggest that epigenetics may play an important role in the pathogenesis of SLE with AS.

Objective To study the intestinal microflora changes in children with Henoch-Sch?nlein purpura (HSP). Methods The feces of 64 children with HSP (the experimental group) and 25 healthy children (the control group) were collected. 16S rRNA/DNA fluorescent quantitative polymerase chain reaction were performed to detect bacterial content of Lactobacillus, Biifdobacterium and Escherichia coli in feces. Results The amounts of Lactobacillus, and Biifdobacterium in the HSP group were lower than those of the healthy group, and the amounts of E.coli were higher, but the differences were not statistically signiifcant. The amounts of Lactobacillus and Biifdobacterium in the HSP children with gastrointestinal symptoms (abdominal pain, vomiting, e.g.) were signiifcantly lower than those in HSP children without gastrointestinal symptoms and in the healthy group. The difference was signiifcant (P<0.05). Conclusions It suggests that intestinal microlfora in children with HSP in acute phase may exist disorders, especially in the HSP children with gastrointestinal symptoms.
