Objective To explore the value of evaluating rat liver fibrosis using contrast enhanced sonography.Methods Carbon tetrachloride was used to induce liver fibrosis.Under the mode of pulse-inversion harmonic imaging,ultrasound contrast agent was bolus iniected through tail vein,hepatic artery arrival time(HAAT),portal vein arrival time(PVAT),hepatic vein arrival time(HVAT)was recorded,and their relationship with immunohistochemical results were analyzed.Results There was no statistical difference of HAAT,PVAT between two groups among S0-S4 stage.HVAT was shorter in S3 and S4 stage than in S0-S2 stage(P＜0.05).HVAT was negative correlated with the percentage of immunohistochemical positive area of C-Ⅳ,LN,the correlation coefficients were-0.680 and -0.639 respectively.Conclusions Contrast enhanced sonography is useful for the diagnosing liver fibrosis.

OBJECTIVE: To explore the role of the innate immune factors TLR2 and TLR4 in the pathogenesis of chronic rhinosinusitis (CRS) by detecting their expression in different clinical types of CRS and the normal control group. METHOD: Immunohistochemistry was used to detect the expression of TLR2 and TLR4 respectively in 21 cases (chronic rhinosinusitis with nasal polyps, CRSwNP) group, 15 cases (chronic rhinosinusitis without nasal polyos, CRSsNP) group, 11 cases recurrent CRSwNP group and 13 cases control group. Positive cells were counted under the microscope artificially, Mann-Whitney U analysis was applied for the ranked data, and one-way anova analysis was adopted to analyze the experimental group and control group. RESULT: (1) TLR2 and TLR4 expression had the same characteristics. Expression mainly concentrated in parts of the whole layer of epithelial basement membrane, cytoplasm of glandular cells, very few inflammatory cells such as monocytes and plasma cells in the cytoplasm, sometimes unknown cell nuclei positive expression. (2) The glandular cells were stained manual counting and color grading. TLR2 and TLR4 packet application Wilcoxon rank test Mann-Whitney U test analysis was not statistically significant (P > 0.05), measurement data within the group variance statistical difference between the groups (P < 0.05). CONCLUSION The Nasal mucosa can produce the innate immune factors TLR2 and TLR4. The different expression of TLR2 and TLR4 in the various clinical types of CRS suggests that they play the certain role in the pathogenesis of CRS.
