Objective To investigate the MR features of adenomyosis and its diagnostic value.Methods Forty-six patients with suspicious adenomyosis underwent preoperative ultrasound and MR exam.Inversion recovery sequence(IR)T 1-weighted images and turbo spin echo sequence(TSE)including T 1-weighted and T 2-weighted images were adopted.All patients were performed with contrast enhancement.Comparative analysis between MRI findings and pathology results was done. Results The diagnostic specificity,sensitivity and accuracy of MRI was 100%,94.74% and 97.14% respectively.The effect of MRI for diagnosis of adenomyosis was better than that of US significantly.All cases showed enlargement of uterus with regular contour.Diffuse and local thickening of junctional zone or low signal intensity lesion in outer myometrial layer was found on T 2-weighted images,sometimes bright foci observed in lesion on T 2-weighted images or on T 1-weighted images.Conclusion MRI has high value in gualitative diagnosis and localization of adenomyosis.It can be used as an important complementary method to ultrasound.

OBJECTIVE To investigate the association between 592C/A and-819C/T of interleukin-10 gene polymorphism in patients with immediate ?-lactam drug allergy in Chinese Han population.METHODS The genotype and allele frequency of interleukin-10 gene were studied by polymerase chain reaction-restriction fragment length polymorphism(PCR-RFLP)in 44 Chinese Han patients with evidence of immediate ?-lactam drug allergy and 44 controls subjects.They all matched for sex and atopy,the production was investigated by sequence analysis.RESULTS Our analysis did reveal differences in the distribution of the single nucleotide polymorphism(SNP)between female allergic patients and controls.Among allergy subjects,we found two distinct significant associations between immediate drug allergy women and two linked IL-10 promoter genes polymorphism,-592C/A and-819C/T(P

Objective To investigate the impact of suppressor of cytokine signaling 1 (SOCS1) overexpression on dendritic cells (DC) functions and its therapeutic effect on acute liver failure (ALF) in mice.Methods Bone marrow derived dendritic cells (BMDC) from C57BL/6 mice were transfected with lentivirus encoding SOCS1 and negative control lentivirus at a MOI=50, and labeled as DC-SOCS1and DC-VNG, respectively after 96 hours of successful transduction.Then DCs were stimulated with lipopolysaccharides(LPS)1 mg/L and collected for flow cytometry analysis of surface costimulatory molecules, allogeneic mixed lymphocyte reaction (MLR) and western blot test of Janus kinase (JAK)/signaling transducers and activators of transcription (STAT) pathway.Afterwards, 90 mice were randomly assigned into 4 groups including 12 in normal control group, 26 in ALF group, 26 in treatment groups with DC-SOCS1 and 26 with the treatment of DC-VNG.All were received tail vein injection with normal saline, modified DC-VNG and DC-SOCS1 suspended in normal saline, respectively.Twelve hours after injection, LPS (10 μg/kg)/D-GaIN (600 mg/kg) were injected intraperitoneally to induce ALF model.The mortality, serum levels of alanine aminotransferase (ALT) and aspartate transaminase (AST), liver pathology and proportion of splenic regulatory T cells of each group were observed.Means in different groups were compared with one-way ANOVA analysis.Categorical variables were analyzed with x2 test.Variables were examined with normality test and homogeneity of variance with LSD test.Results The results of mixed lymphocyte reaction (MLR) revealed that T cell proliferation ratio in DC-SOCS1 group with mixture ratio of 100∶1 were (25.87±0.38)%, which was lower than that of mixture ratio of 10∶1 in the mDC group ([84.29±3.25]%) with statistical significance (x2=49.821, P<0.01);interleukin (IL)-10 concentration was higher than that in mDC group with mixture ratio of 10∶1 with statistical significance (F=20.112, P<0.05);IL-6 concentration was also lower with statistical significance (F=47.718, P<0.05).Compared to imDC, expression of JAK2 (t=0.525,0.523 and 0.489, respectively, all P<0.01), signal transduction factors and activation of transcription factors-1 (STAT1) (t=0.442,0.400 and 0.402, respectively, all P<0.01) and SOCS1 (t=0.322,0.363 and 1.090, respectively, all P<0.01) of mDC, DC-VNG and DC-SOCS1 after LPS stimulation increased significantly.Furthermore, the expressions of phosphorylated STAT1 (p-STAT1) and phosphorylated JAK2 (p-JAK2) of DC-SOCS1 were much lower than those of the mDC, with statistically significant difference (t=-3.840 and 0.254, respectively, both P<0.01).Pathological analysis revealed that there existed moderate hepatic cells necrosis and less immune cell infiltration in DC-SOCS1 group accompanied with higher regulatory T lymphocytes proportion than those in ALF group and DC-VNG group.Survival rate of ALF with DC-SOCS1 treatment group was significantly higher than that of ALF group with statistical difference (x2=12.87, P<0.05).Conclusions DC-SOCS1could sustain an immature state and exhibit as regulatory DC through negative regulation of JAK2/STAT1 pathway with overexpression of SOCS1.Infusion of DC-SOCS1 could ameliorate ALF by inhibiting aggressive inflammation response with increased proportion of regulatory T cells in mice, which shows good therapeutic effect for ALF mice.
