Objective To investigate the diagnosis value of spleen stiffness measurement by transient elastography (FibroScan, FS) for esophageal-gastric varices (EV) in patients with HBV-related liver cirrhosis receiving anti-viral treatment. Method Total of 41 patients from Jan 2014 to Dec 2014 diagnosed with HBV-related liver cirrhosis receiving anti-viral treatment were enrolled. All patients were evaluated for spleen and liver stiffness measurement by FS and checked by gastroscopy for diagnosis of EV. Using gastroscopy as the gold standard, the area under receiver operating characteristic curve (AUROC) were used to evaluate the value of the spleen stiffness and liver stiffness in diagnosis of EV and its degree. Results The spleen and liver FS values in patients were (40.64 ± 25.45) kPa and (20.76 ± 13.21) kPa respectively, and they showed a positive correlation (r = 0.402, P < 0.001). The spleen FS values in patients without EV were significantly lower than those in patients with mild EV and moderate-severe EV (all P < 0.05). Furthermore, they showed significantly lower in patients with mild EV than those in patients with moderate-severe EV too (P < 0.05). The AUROC of spleen FS in patients with EV was 0.863, with sensitivity of 79.4% and specificity of 83.2%. Moreover, the AUROC of spleen FS in patients with moderate-severe EV was 0.924, with sensitivity of 87.9% and specificity of 91.3%. Both of them were much higher than those of liver FS. Conclusion Spleen FS may act as a non-invasive marker to predict EV and its degree in patients with HBV-related liver cirrhosis receiving anti-viral treatment.

OBJECTIVE To investigate the protective effect of interleukin-35(IL-35)mRNA-lipid nanoparticles(LNP)against lipopolysaccharide(LPS)-induced acute lung injury(ALI)in mice.METHODS Fifity-six mice were randomly divided into 7 groups with 8 mice in each,including the normal control group,IL-35 mRNA-LNP(250 μg·kg-1)group,LPS group,LPS+IL-35 mRNA-LNP(50,125 and 250 μg·kg-1)group and LPS+Dexamethasone(DXM)group.Except for the normal control group and IL-35 mRNA-LNP(250 μg·kg-1)group and ALI model was established by tracheal infusion of LPS in each of the other groups.IL-35 mRNA-LNP(250 μg·kg-1)group and LPS+IL-35 mRNA-LNP(50,125 and 250 μg·kg-1)group were injected with a corresponding dose of LNP encapsulated mRNA complex via the tail vein while the LPS+DXM group was injected with DXM via the tail vein.Lung coefficient and the wet to dry weight ratio(W/D)of lung tissue were recorded.The mRNA levels of inflammatory cytokines tumor necrosis factor-α(TNF-α),Interleukin-6(IL-6)and IL-1βof lung homogenates were detected by real-time fluorescence quantitative PCR(RT-qPCR).LDH activity of lung homogenates and the protein levels of IL-35,TNF-α,IL-6 and IL-1β in lung homogenate were detected by corresponding kits.Hematoxylin-eosin(HE)staining was used to observe and analyze the pathological injury to lung tissue.The expres-sion of Lymphocyte antigen 6G(Ly6G)was detected by Immunofluorescence to reflect the infiltration of neutrophils.RESULTS Compared with the normal control group,LPS group and LPS+DXM group,IL-35 protein expression levels in lung homogenates of the other groups were more significant(P<0.01).Compared with the normal control group,lung coefficient,W/D ratio of lung tissue,LDH activity,mRNA levels and the protein levels of TNF-α,IL-6 and IL-1β in lung homogenates were significantly increased in the LPS group(P<0.01),accompanied by alveolar hemorrhage,alveolar wall thickening and neutro-phils infiltration.After IL-35 mRNA-LNP administration,lung coefficient,W/D ratio of lung tissue,LDH activity,mRNA levels and the protein levels of TNF-α,IL-6 and IL-1β in lung homogenates were signifi-cantly decreased(P<0.01),and alveolar hemorrhage,alveolar wall thickening and neutrophil infiltration were obviously improved.CONCLUSION IL-35 mRNA-LNP can express IL-35 protein in lung tissue of mice,and effectively improve LPS-induced ALI in mice by inhibiting the expression of proinflammatory factors.
