OBJECTIVETo investigate the inhibitory effects of OMT on TGF-β1-induced CFBs proliferation, and then explore the mechanism.
METHODThe experiment was randomly divided into 6 groups as following: control group (serum free DMEM), model group (20 μg x L(-1) TGF-β1), OMT low dose group (1.89 x 10(-4) mol x L(-1) + 20 μg x L(-1) TGF-β1), OMT medium dose group (3.78 x 10(-4) mol x L(-1) + 20 μg x L(-1) TGF-β1), OMT high dose group (7.56 x 10(-4) mol x L(-1) + 20 μg x L(-1) TGF-β1), SB203580 group (p38MAPK blocking agent, 1 x 10(-5) mol x L(-1) + 20 μg x L(-1) TGF-β1). Vimentin of CFBs was identified by immunocytochemical methods, α-SMA of myFBs as well. Inhibitory effects of OMT on CFBs proliferation was detected by the MTT assay. Picric acid Sirius red staining was analyzed collagen type I and collagen type III deposition. Western blot was determined the expression of p38MAPK, p-p38MAPK, collagen type I and collagen type III.
RESULTMTT results showed that OMT significantly inhibited CFBs proliferation induced by TGF-β1 (P < 0.01) α-SMA immunocytochemical experiments suggested that OMT could protect against the CFBs proliferation. OMT could significantly decrease the deposition of collagen type I and collagen type III by Western bloting and picric acid Sirius red staining. Western blot results showed that TGF-β1 enhanced p38MAPK phosphorylation, however OMT attenuated the phosphorylation of p38MAPK induced by TGF-β1 (P < 0.01).
CONCLUSIONOMT can inhibit the CFBs proliferation induced by TGF-β1, and its mechanism may be involved in inhibiting p38MAPK phosphorylation.

OBJECTIVE:
To analyze the clinical features and prognosis in patients with primary Sjögren's syndrome (pSS) and autoimmune liver diseases (ALD).
METHODS:
A retrospective analysis of clinical manifestation and prognosis was performed in patients with ALD or without ALD during the three years (February 2014 to December 2017).
RESULTS:
Totally, 203 patients with pSS were included in this study, 68 patients had ALD (31 patients with autoimmune hepatitis, 37 patients with primary biliary cholangitis), while 135 patients did not have ALD. There were no differences between the two groups regarding age, gender, clinical manifestations, such as dry mouth, dry eyes, pain, fatigue, lymphadenopathy, glandular swelling, cutaneous involvement, lung involvement, and renal involvement, and the incidence rate of other autoimmune diseases, such as autoimmune thyroid disease, rheumatoid arthritis, and vasculitis. There were also no differences in the titer of antinuclear antibody (ANA), the positive rates of anti-Sjögren's syndrome A antibody (SSA), SSA52, and anti-Sjögren's syndrome B antibody (SSB), and at the levels of erythrocyte sedimentation rate and C-reactive protein between the two groups. Most importantly, the pSS patients with ALD had a shorter disease course, a higher positive rate of anti-mitochondrial M2 antibody (AMA-M2) and anti-centromere antibody, a higher level of IgG and IgM, a lower level of complement 3, and a decreased number of blood cells. They also had a higher level of liver related serum index, such as alanine aminotransferase, aspartate aminotransferase, gamma-glutamyl transferase, alkaline phosphatase and total bilirubin, direct bilirubin, indirect bilirubin, a higher incidence rate of liver cirrhosis, an increased death incident (the mortality was 13.24% in the pSS patients with ALD, while 2.96% in the controls, P=0.013), and a worse prognosis. Binary Logistic regression analysis revealed that liver cirrhosis, the EULAR Sjögren's syndrome disease activity index (ESSDAI) scores and the level of total bilirubin were the prognostic factors of mortality in the pSS patients with ALD. The survival curve was estimated by the Kaplan-Meier method. It demonstrated that the pSS patients with ALD had a lower survival rate when compared with the controls.
CONCLUSION
The patients with both pSS and ALD will suffer from a more severe disease and a higher death incident. We should pay more attention to these patients and provide a better symptomatic treatment for them during clinical practice.
