BACKGROUNDEndocervical epithelial cells play early roles in the defense of upper female genital tract to pathogens. Toll-like receptors (TLRs) and human defensins (HD) have recently been identified as fundamental components of the innate immune responses to bacterial pathogens. We aimed to use in vitro model of human primary endocervical epithelial cells (HPECs) to investigate their roles in innate immune response of the endocervix.

METHODSTLR4 expression and distribution in HPECs and endocervix were investigated by immunofluorescence (IF). Cultured HPECs were divided into lipopolysaccharide (LPS) group which were treated by LPS for 0, 24 and 48 hours, and control group without treatment. At each time point, the levels of HD5, IL-6 and TNF-alpha in supernants were determined by ELISA. TLR4 and HD5 expressions of cells were detected by Western blotting simultaneously. HD5 expression pattern was also compared between the HeLa cell line and HPECs.

RESULTSEndocervix tissue surface and HPECs expressed TLR4. After incubated with LPS, HPECs expressed significantly higher levels of TLR4 than control group, especially after 24 hours (P < 0.01), however decreased after 48 hours with a similar level of TLR4 expression compared with control group. LPS could upregulate the secretion of HD5, IL-6 and TNF-alpha in a time-dependent manner (24 hours: P < 0.05; 48 hours: P < 0.01, compared with control group). Intracellular HD5 expression levels decreased over time. HD5 expression patterns in HPECs were different from HeLa cell line.

CONCLUSIONSTo respond to LPS stimulation, HPECs may function in the mucosal immune defense through TLR4 activation and HD5 secretion. HPEC is considered a significant model for immunological study.

Introduction: Tuberculosis (TB) in internal migrants is one of three threats for TB control in China. To address this threat, a project was launched in eight of the 19 districts of Shanghai in 2007 to provide transportation subsidies and living allowances for all migrant TB cases. This study aims to determine if this project contributed to improved TB control outcomes among migrants in urban Shanghai. Methods: This was a community intervention study. The data were derived from the TB Management Information System in three project districts and three non-project districts in Shanghai between 2006 and 2010. The impact of the project was estimated in a difference-in–difference (DID) analysis framework, and a multivariable binary logistic regression analysis. Results: A total of 1872 pulmonary TB (PTB) cases in internal migrants were included in the study. The treatment success rate (TSR) for migrant smear-positive cases in project districts increased from 59.9% in 2006 to 87.6% in 2010 (P < 0.001). The crude DID improvement of TSR was 18.9%. There was an increased probability of TSR in the project group before and after the project intervention period (coefficient = 1.156, odds ratio = 3.178, 95% confidence interval: 1.305–7.736, P = 0.011). Conclusion: The study showed the project could improve treatment success in migrant PTB cases. This was a short-term programme using special financial subsidies for all migrant PTB cases. It is recommended that project funds be continuously invested by governments with particular focus on the more vulnerable PTB cases among migrants.

Objective To investigate the expression pattern of transcription factor Olig 2 in cuprizone-induced mouse model of acute demyelination .Methods C57BL/6 mice were fed with 0.2%cuprizone to induce acute demyelina-tion.Immunofluorescence and qRT-PCR were used, and Olig2, MBP and GFAP were detected in the brain tissues of con-trol group and cuprizone-treated groups for 6 weeks and recovery for 2 weeks.Results Severe demyelination occurred in the corpus callosum following 6-weeks exposure to cuprizone , while remyelination was detected in the white matter after the mice were given diet without cuprizone .In the normal mice , Olig2 was expressed in a low level , while the experessions of Olig2 and GFAP were significantly increased , and Olig2 +/GFAP+cells were detected after demyelination .But the expres-sion of MBP was below the normal level with demyelination .After recovery for 2 weeks, the experession of Olig2 was lower, but the experessions of MBP and GFAP were increased .Conclusions Olig2 may play an important role in the glial differ-entiation from neural progenitor cells into active astrocytes , and in the glial scar formation .

Objective To investigate auditory sensory gating potential in the siblings of schizophrenic, to discover the neuroimaging features of sensory gating associated with schizophrenia as intermediate phenotypes. Methods Twelve siblings of schizophrenia patients in the first episodic, and 12 healthy controls matched in gender, age, education under?went MRI scan when performing a auditory sensory gating fMRI task (repeated clicks and single click auditory stimuli). The measure of sensory gating was the contrast of repeated clicks minus single click. The analysis of result was imple?mented in SPM2. Results Compared with healthy controls, schizophrenia patients showed significant overactivation in the right inter cingulate gyrus (x=4,y=8,z=32) and left anterior cingulate gyrus (x=-8,y=4,z=28) during the fMRI senso?ry gating task. Conclusion Sensory gating is overactivated in the cingulate gyrus in siblings of schizophrenic. This pat?tern may be a potential endophenotype of schizophrenia.

AIM:To observe the inhibition effect of endostatin ( endostar ) on mice choroidal neovascularization model ( CNV) and compare with the Avastin.
METHODS: Using 532nm laser photocoagulation to establish a mouse model of CNV. We observed the formation of CNV by histopathological examination after 2wk later. Forty successful models of mice were randomly divided into control group (group 1, 10 rats), normal saline group ( group 2, 10 rats ), endostatin group (group 3, 10 rats) and avastin group (group 4, 10 rats) . The drugs were injected into the mice' vitreous after photocoagulation 2wk later. Then 1wk later, we took the mice eyeballs to perform the HE and immunohistochemical staining to observe. The statistical analysis of ANOVA was done by SPSS 16. 0 and the LSD-t test was used for multiple samples, taking P<0. 05 as the test standards.
RESULTS: Two weeks later, HE histopathological examination was done , light microscope showed large amount of new vessels' formation, the positive rate for CNV was 72. 8%. The blank control group compared with the normal saline group P>0. 05, had no inhibitory effect on CNV;endostatin treated group compared with control group, P<0. 05, had a certain inhibitory effect; avastin group compared with the control group, P<0. 05, had an inhibitory effect on CNV; the LSD-t was performed on Avastin group and endostatin group, P<0. 05, which were statistically significant. We thought that the two drugs have different inhibitory effect on mice' CNV, because xAvastin=26. 90 ,xendostatin=29. 13,xAvastin CONCLUSION: Laser-induced CNV animal models of colored mice C57BL/6J is of short time and high rate establishment and it is an ideal model for CNV study. Endostar has certain inhibitory effect on CNV, and it is likely to become one of the important drugs for CNV-related diseases in the future.
