BACKGROUND:How to promote homing of scarce limbal stem cel s is the key to improving transplantation efficiency. And stromal cel-derived factor-1 plays an important role in the repair of retinal pigment epithelial cel s injury. OBJECTIVE:To observe changes of stromal cel-derived factor-1 levels in rat and mouse limbal stem cel deficiency models in order to confirm whether these changes wil induce peripheral blood stem cel s homing into the cornea. METHODS:Eye models of limbal stem cel deficiency were prepared in rats and mice by cutting method, then peripheral blood samples were continuously drawn to detect the mass concentration of stromal cel-derived factor-1 by enzyme-linked immunosorbent assay within 1 month after modeling. RESULTS AND CONCLUSION:In the rat peripheral blood, the mass concentration of stromal cel-derived factor-1 started to increase at 24 hours after modeling and firstly peaked at the 3rd day;then it tended to decrease and reached a second peak lower than the first one at the 25th day;subsequently, it returned to the normal level. In the meanwhile, the mass concentration of stromal cel-derived factor-1 in the mouse peripheral blood, increased at 12 hours after modeling, peaked at the 3rd day, subsequently decreased until another peak lower than the former one presented at the 20th day, and final y it returned to the normal level. In conclusion, the level of stromal cel-derived factor-1 in the peripheral blood is significantly associated with limbal stem cel s deficiency, which may play an important role in corneal injury repair.

BACKGROUND:Stromal cel-derived factor-1 (SDF-1) and chemokine receptor-4 (CXCR4) play an important role in stem cel homing during bone marrow, organ and tissue transplantation. But there are few reports on limbal stem cel transplantation and homing as wel as the distribution and content of SDF-1/CXCR4 on the cornea. OBJECTIVE:To detect the expression levels of SDF-1/CXCR4 mRNA in rat corneal tissue by fluorescence quantitative PCR. METHODS: The normal rat cornea was taken completely, and subdivided into central cornea, peripheral corneal and limbal area. Fluorescence quantitative PCR method was employed to detect SDF-1/CXCR4 mRNA levels at corresponding positions. RESULTS AND CONCLUSION: The expression levels of SDF-1 and CXCR4 mRNA were 0.213±0.015 and 0.189±0.02 in the central cornea, 0.529±0.077 and 0.285±0.015 in the peripheral cornea, 0.666±0.069 and 0.258±0.067 in the limbal area, respectively. These data show that there are significant differences in the expression levels of SDF-1 and CXCR4 mRNA in the central cornea, peripheral corneal and limbal area, and these differences exert an important role in cel homing and migration during limbal stem cel transplantation for treatment of limbal stem cel deficiency.

Objective Dynamic contrast enhanced magnetic resonance imaging (DCE-MRI) is a novel functional imaging tech-nique for assessing the property of the tissue vessel .This study was to investigate whether DCE-MRI can manifest the angiogenesis of pri-mary liver cancer in the aspect of vascular permeability so as to provide more objective diagnostic information for the evaluation of primary liver cancer . Methods Twenty-one patients with primary liver cancer underwent DCE-MRI.The region of interest ( ROI) was placed in the whole tumor, the hot spot of the tumor and the adjacent liver parenchyma .Tissue 4D software package was used for the post-pro-cessing of the DCE-MRI images, the quantitative parameters including transfer constant (Ktrans), rate constant (Kep) and tumor extravas-cular extracellular space volume (Ve), and such semi-quantitative parameter as the initial area under the contrast concentration versus time curve (iAUC). Results The mean Ktrans, Kep, Ve and iAUC values were (0.124 ±0.057)/min, (0.632 ±0.158)/min, (0.205 ±0.098) and (10.009 ±6.201) in the adjacent liver parenchyma , (0.196 ±0.109)/min, (0.546 ±0.214)/min, (0.424 ± 0.160) and (13.675 ±6.113) in the whole tumor, and (0.422 ±0.170)/min, (0.780 ±0.308)/min, (0.589 ±0.116) and (35.663 ±19.086) in the hot spot of the tumor .All the parameters were significantly higher in the hot spot of the tumor than in the whole tumor (P<0.05), and so were Ktrans and Ve in the whole tumor than in the adjacent liver parenchyma (P<0.05), but Ktrans, Ve, and iAUC were markedly lower in the adjacent liver parenchyma than in the hot spot of the tumor (P<0.05). Conclusion Analysis of the vascular permeability of the tissue using DCE-MRI parameters can indirectly reflect the angiogenesis of the tumor and contribute to the evaluation of primary liver cancer , while monitoring the DCE-MRI pa-rameters of the hot spots of the tumor may allow more accurate evalua-tion of primary liver cancer .

False and negative information has brought forth serious impacts on doctor-patient relationship in the new media era as a result of “Broken window effect”and “Butterfly effect”.The underlying reasons are herd mentality,the public’s need to vent their discontent,the subjectivity of information distribution on the Internet and lack of proper supervision and punishment mechanism.Medical Institutions should pay special attention to the new media,leveraging it to improve doctor-patient relationship by making official voice,guiding public opinion,solving problems,and providing comfortable social environment and rational public opinion environment on the Internet.

0.4,P0.05)with HHS.[Conclusion]The result of this study suggest that HHS can not capture additional important quality of life domains except for physical function and pain relief that are influenced by THA.So it's necessary to combine HHS and a quality of life survey such as SF-36 to allow a more global assessment of THA.

Objective To investigate the effect of triptolide on asthmatic airway remodeling and signal transducer and activator of transcription 6 (STAT6), acid neutrophil chemokines (eotaxin) impact. Methods The total of 30 mice with ovalbumin (OVA) model of asthma were randomly divided into three groups, control group, asthma group and triptolide group. After 24 hours of the last shot, lung tissue was stained Bronchial inflammatory cell infiltration was determined by using semi-quantitative method and calculate the proportion of goblet cells in airway epithelial cells. Hydroxyproline was determined by McMillan airway mucus score. The mRNA level and protein level of STAT6 and eotaxin in airway epithelium were determined by RT-PCR and immunohistochemistry. Results Compared with asthma group, peribronchial inflammatory cells infiltration of triptolide group were reduced, which mucus index is (1.31 ± 0.23) and hydroxyproline is (284 ± 13) μmg/100 mg. it had a significant in asthma group (P < 0.05). Besides, the protein level and mRNA level of STAT6 and eotaxin were significantly decreased (P < 0.05). Moreover, it was a positive correlation between STAT6 and eotaxin level in airway epithelial (r = 0.668, P < 0.05). Conclusion Triptolide can inhibit airway remodeling and might through the down regulation of STAT6 and eotaxin expression.
