5.Role of Toll-like receptor 4 and human defensin 5 in primary endocervical epithelial cells.
Chinese Medical Journal 2010;123(13):1762-1767
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.

BACKGROUND: Directly percutaneous injection of protein-denaturant hydrochloric acid (PDHA) into tumors can lead to fast killing of tumor, sustained drug release and prevention of in situ recurrence of tumor. However, whether implants can be used combined with denaturant still remains unknown. OBJECTIVE: To investigate the compatibility of fluorouracil implants and PDHA (6 mol/L). DESIGN, TIME AND SETTING: Observational study was performed in the Hefei Industry University between October 2006 and March 2007. MATERIALS: A total of 78 Wistar rats, weighing (200i20) g, half males and half females, were used for testing drug release in vivo. Drugs fluorouracil implants (H20030345; columniform particle, diameter 0.8 mm, length 4 mm; specifications: Fluorouracil 2 mg/particle; batch number: 20060922; meeting the National Drug Quality Standards [WS1-(X-103)-2005Z]) were provided by Wuhu Zhongren Pharmaceutical Company,Ltd. Hydrochloric acid (37%) was analytical reagent. METHODS: 96 tubes of the implants and PDHA were kept at (37.0± 0.5) ℃. Each time, six samples were collected at 1, 8, 16, 24, 96, 120, 168, 240, 360, 432, 480, 528, 600, 720, and 960 hours after incubation. Appearance of the implants was observed by microscope. Stability of fluorouracil in PDHA was determined by HPLC and ultraviolet absorb method. Based on the entering quantity and residual quantity of fluorouracil, the release rates were calculated. MAIN OUTCOME MEASURES: The approximate solubility, stability and morphological change of fluorouracil in denaturant and the corresponding drug release character in both denaturant and rats in vivo. RESULTS: At (37.0±0,5) ℃, the fluorouracil was stable for 960 hours in PDHA, the saturated concentration of fluorouracil was (22.72±0.04) g/L. The appearance of implants was intact. The surface was porous. Compared with the speed of releasing drug in rats, the speed of releasing drug was faster in the early stage of release process and slower in the later stage. The drug release was incomplete. At 1, 24, 96, 360 and 960 hours, the implants' release rates were (11.9±6.7)%, (37.9±5.3)%, (52.6±4.5)%, (75.3±3.8)%, and (85.5±2.1)%, respectively. CONCLUSION: The fluorouracil implants and hydrochloric acid (6 mol/L) are compatible and no influence is detected during the observation.

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.
