Objective To study the regulation of quorum sensing molecule tyrosol and farnesol on biofilm formation of Candida albicans. Methods Candida albicans biofilms of clinic isolates and standard strain SC5314 were built when quorum sensing molecule existed. And inverted microscope was used to observe the morphology of C. albicans cells. RT-PCR and MTT assay were carried out to investigate the effect of quorum sensing molecule on expression of the two genes (HTA1 and EFG1) and cytoactive. Results Tyrosol could not promote hyphae development and cytoactive of C. albicans biofilms. The expression of HTA1 of C. albicans in biofilms was up-regulated by tyrosol but EFG1 was not. The inhibitory effect of farnesol on hyphae development, cytoactive and gene expression were not changed by addition of tyrosol. Conclusion Tyrosol can make C. albicans biofilms active in early stage. But when tyrosol and farnesol were simultaneously added, the effect of tyrosol were masked by farnesol. And C. albicans cells were more sensitive to farnesol than to tyrosol.

Objective To detect the expression of osteopontin (OPN) in cervical local tissues of patients with chronic cervicitis, cervical intraepithelial neoplasia (CIN), cervical cancer. To investigate the possibility that OPN is used as tumor marker of cervical cancer. Methods The expression of OPN in 25 cases of chronic cervicitis, 18 cases of CIN and 21 cases of cervical cancer was detected by immuohistochemistry SP method. Results The positive expression rates of OPN in the chronic cervicitis, CIN and the cervical cancer had a rising trend (48 %, 77.78 % and 80.95 %, respectively) and their differences had statistical significant (P <0.05). The OPN expression level in cervical cancer had no statistical correlation with age, tumor size, clinical stage and other clinical pathological features (P >0.05). Although OPN expression level in cervical cancer wasn' t related with tumor clinical stage, positive expression rates of OPN had a gradually increased trend along with the clinical stage. Conclusion High expression of OPN is found in cervical cancer and may be related to the occurrence and development of cervical cancer.

Objective To establish a biotin-streptavidin ELISA method to measure CTGF,and evaluate the clinical value of CTGF for the diagnosis of liver fibrosis in chronic hepatitis B (CHB) patients.Methods Biotinylated anti-CTGF polyclonal antibody and monoclonal antibodies were prepared for the establishment of this biotin-streptavidin ELISA method.Two hundreds and sixty-four CHB patients were subjected into non-or mild liver fibrosis group (S0-S1,108 cases) and severe liver fibrosis group (S2-S4,156 cases),according to the liver biopsy pathological diagnosis.The CTGF assay's diagnostic capacity for CHB was assessed by comparing the area under ROC (AUC) with that of a panel of hepatic fibrosis markers ( HA,PC Ⅲ,C Ⅳ,LN and APRI).Analysis of variance and rank sum test were performed to carry out comparisons between multiple groups.Student's t-test and Mann-Whitney U test were performed for the pairwise comparison between multiple samples.Spearman rank correlation test was performed to analyze the correlation between different hepatic fibrosis stages.Results The minimum detectable dose and detection rang of the ELISA was 0.2 μg/L and 0-64 μg/L respectively.The intra-assay and inter-assay CV at high and low level were 4.5％,9.8％ and 10.1％,12.8％ respectively.Serum CTGF concentrations in S0-S1 group and S2-S4 group were 6.7(3.1 - 10.1 ) μg/L and 16.1 ( 11.8 -27.2) μg/L,with a statistically significant difference (U =1 217,P ＜0.001 ).There was a significant correlation between the levels of serum CTGF and fibrosis stages ( r =0.689,P ＜ 0.001 ),AUC of CTGF was 0.841 (95％ CI:0.762 - 0.920) in distinguishing mild fibrosis from significant fibrosis.When the cut-off value of CTGF was 10.3 μg/L,the sensitivity and specification was 70.5％ and 82.4％ respectively.The sensitivity of parallel combination test of CTGF and APRI was 96.1％,which was higher than that of HA (75.6％),PC Ⅲ (70.5％ ),C Ⅳ(63.6％),LN(79.5％ ),APRI(86.3％ ).The specificity of the combination test was 65.5％,which was lower than of above liver fibrosis markers [HA ( 72.5％ ),PC Ⅲ ( 76.5％ ),C Ⅳ ( 78.4％ )].The specificity of serial combination test of CTGF and PC Ⅲ was 95.9％,which was higher than that of HA,PC Ⅲ,CⅣ,LN(64.7％ ),APRI(66.1％ ),however,the sensitivity of the combination test was 67.7％,which was lower than that of above HA,PC Ⅲ,and APRI.Conclusions The biotin-streptavidin ELISA method measuring serum CTGF has a high minimu detectable dose sensitivity,and specificity.Serum CTGF level is significantly correlated with fibrosis stage,and CTGF maybe a valuable marker for liver fibrosis assessment.The paralledl combination of CTGF and APRI could be used as screening for significant liver fibrosis markers.The serial combination of CTGF and PC Ⅲ may be considered as a confirmatory diagnostic marker for liver fibrosis.
