Objective To study the activation of Janus protein tyrosine kinase (JAK)/signal transducer and activator of transcription 1 (STAT1) signaling pathway and its inhibitor-signal transducer and activator of transcription-1(SOCS-1) in patients with systemic lupus erythematosus. Methods A total of 45 patients with active systemic lupus erythematosus (SLE) and 30 healthy controls were randomly selected. Western blot was performed to measure the expression of Stat1 protein and phospho-Stat1 protein (an activated form of Stat1 protein) in the monocytes after stimulation with recombinant high mobility group box1 (rHMGB1) at various time points. Expression of Stat1 protein in the skin or lesional skin was also detected. Phasic expressions of SOCS-1 mRNA in the monocytes after rHMGB1 stimulation were detected by real-time reverse transcription-polymerase chain reaction. SOCS-1 gene expression in the skin or lesional skin was also detected. Results The expression level of Stat1 proteins in the monocytes from patients with SLE was higher than that from healthy controls (t=9.16,P<0.01) and positively correlated with SLE disease activity index (SLEDAI) (r=0.59,P<0.01). Expression of phospho-Stat1 in the monocytes from SLE patients was time-dependently upregulated after stimulation with rHMGB1 at various time points, while expression of SOCS-1 mRNA remained unchanged(all P>0.05). Expressions of phospho-Stat1 protein and SOCS-1 mRNA in the monocytes from healthy controls were increased transiently after stimulation with rHMGB1(all P<0.05). Both expressions of phospho-Stat1 protein and SOCS-1 gene in the lesional skin from patients with SLE were upregulated compared with those in normal skin from healthy controls (all P<0.01). Conclusion There are hyperactivation of JAK-STAT1 signaling pathway and negative feedback down-regulation of SOCS-1 in patients with systemic lupus erythematosus. HMGB-1 may be partly involved in the pathogenesis of SLE by the abnormal mediating function of JAK-STAT1 signal transduction pathway.

Objective To discuss the clinical value of ultrasonic elastography for thyroid nodules,and compared with pathology.Methods 77 patients with 105 thyroid lesions were analyzed.Tissue stiffness on elastography was scored from one(greatest elastics train)to five (no strain).Results On elastography:scores 1 and 2 were found in 75% benign lesions.Scores 3 to 5 were found in 97.4% malignant lesions.There were statistically difference in the scores of elastography between the benign and malignant lesions (P <0.01).Conclusions The ultrasonic elastography had positive significance in differentiating benign and malignant thyroid nodules.If the score of elastography is more than or equal to 3,the thyroid nodule is highprobablely malignant.
