Objective To select microRNAs (miRNA) associated with human cutaneous malignant melanoma (MM). Methods Total RNA was extracted from 6 tissue samples of MM and 9 human control samples of pigmented nevi, and small RNAs of less than 200 bp were enriched, miRNA microarray was used to select differentially expressed miRNAs between tissue samples of MM and pigmented nevi from 468 candi-dates. The expression of differentially expressed miRNAs was confirmed by fluorescence based real-time quan-titative PCR (qPCR) in all of these samples. Those miRNAs that were identified as differentially expressed with both miRNA microarray and qPCR were considered as significant miRNAs. Results Between the tissue samples of MM and pigmented nevi, 12.18% to 86.33% of miRNAs differentially expressed by more than 2 folds, 1.28% to 19.02% by more than 5 folds, and 0.43% to 5.34% by more than 10 folds. The expression of miRNA-21 was obviously up-regulated, while that of miRNA-320 and miRNA-494 was down-regulated in the MM samples. Conclusion There is an increase in the expression of homo sapiens miRNA-21 but a decrease in that of miRNA-320 and miRNA-494 in MM tissues.

AIM:To analyze the recovery of visual cortex activation range of color vision in anisometropia amblyopia children after treatment by using blood oxygen level dependence-functional magnetic resonance imaging ( BOLD- fMRI ) and SPM8 software.
METHODS:Self-control study. This fMRI study directly compared activity in visual cortex produced by color monocular stimulation in 13 monocular anisometropia amblyopia children. The project of study was blocked design. The data of functions and anatomical MRI was stimulated by three-primary colors and was preprocessed and analyzed by SPM8 that based on MATLAB software. According to the data, we compared the change of the central area of color vision when first visit and 1, 2 ,4wk after treatment.
RESULTS: The BA17, BA18, BA19 and BA37 of amblyopia children were different activated after they accepted the three-primary colors stimulation (P<0. 01). After 4wk treatment, amblyopia children accepted red stimulation, the visual cortex activation range without expanding; after accepting green stimulus, on the left side of the visual cortex BA37, BA19, BA20, the average t value were 3. 5210, 3. 2716, 3. 1534 ( P< 0. 01 ); after accepting blue stimulation, the scope of the right side of visual cortex at BA19, BA18 were expanded to different extent, the average t value were 3. 7345, 3. 2701 (P<0. 01).
CONCLUSION: After 4wk treatment, visual cortex activation of color vision of anisometropia amblyopic children is expanded, but with low extent, after the short-term treatment of amblyopia, visual cortex activation of color vision has a certain degree of recovery but not obvious.

Background It has been proved that as an important adhesion protein of extracellular matrix,osteopontion (OPN) can affect tumor neovascularization.Some new researches showed that anti-OPN antibody plays a role in regulating the neovascular vessel formation.Choroidal neovascularization (CNV) has the same structure with tumor neovascularization,but whether anti-OPN antibody restricts new vessel formation is unclear.Objective This study was to investigate the inhibitory effect of anti-OPN antibody on CNV.Methods Laser-induced CNV models were created in 40 eyes of 40 male SPF C57BL/6J mice by Argon laser photocoagulation of retinas,with the wavelength 514 nm.Thirty-six successful models were randomly divided into anti-OPN antibody group,mouse-IgG group and PBS group by the randomized number table.On the second day after photocoagulation,anti-OPN antibody of 400 μg was intraperitoneally injected in the anti-OPN antibody group,and the equivalent amount of mouse IgG and PBS were used in the same way in the mouse IgG group and PBS group.The CNV was evaluated by fundus fluorescein angiography (FFA) on the seventh days after photocoagulation.The mice were immediately sacrificed and the eyeballs were enucleated on the fourteenth day after photocoagulation,and 4 eyeballs in each group were used to observe the areas of CNV on the retinal pigmental epithelium-choroid-sclera fiat mounts,and the other 8 eyeballs of each groups were used to analyze the expression levels of OPN mRNA and vascular endothelial growth factor(VEGF) mRNA using quantitative fluorescence-PCR (QF-PCR).Results FFA showed fluorescein leakage areas around laser spots 7 days after photocoagulation,indicating that CNV appeared.The CNV areas were ([16.98±0.70] × 103) μm2,([27.13 ± 0.81] × 103) μm2 and ([35.39±2.14] ×103) μm2 respectively in the anti-OPN antibody group,mouse IgG group and PBS group,with a significant difference among the 3 groups (F =533.76,P =0.00),and the CNV area was significantly smaller in the anti-OPN antibody group compared with those of the mouse IgG group and PBS group (q =-3.95,-4.40,both at P<0.05).No significant difference was found in the OPN mRNA expression between the antiOPN antibody group and mouse IgG group (t =-5.26,P =0.66).However,the expression of VEGF mRNA in choroidal tissue was significantly declined in the anti-OPN antibody group than that in the mouse IgG group (t =-6.74,P<0.01).Conclusions Anti-OPN antibody suppresses the formation of CNV in laser-induced mouse model by down-regulating VEGF.

O-GlcNAcylation is the addition of a single N-acetylglucosamine(GlcNAc)moiety to the hydroxyl groups of serine or threonine residues of nuclear and cytoplasmic proteins. The transcription factors, kinases of the metabolic pathways and some cytoplasmic enzymes can be O-GlcNAcylated to affect cell transcription, signal transduction, cell metabolism and other biological functions. Abnormal glucose metabolism of tumors has been a hotspot in the research field of tumor pathogenesis and therapeutic targets recently. O-GlcNAclation regulates the glucose metabolism of tumor by affecting the activity of kinases in the metabolic pathway, which is closely associated with the abnormal glucose metabolism of tumor. The abnormal O-GlcNAcylation is one of the potential reasons of cancer. In this review, in order to provide a theoretical reference for developing anti-tumor targets and drugs targeting O-GlcNAc modification, we briefly summarized how O-GlcNAcylation regulated glucose metabolism on glucose metabolism, glucose uptake, glycolysis, pentose phosphate pathway and tricarboxylic acid cycle in cancer cell.

Objective To investigate the effect of postconditioning with propofol and ischemia on the hepatic ischemia-reperfusion (I/R) injury in rats. Methods Thirty male SD rats weighing 200-250 g were randomly divided into 5 groups of 6 animals each: group I sham operation (group S); groupⅡ I/R; group Ⅲ ischemic postconditioning (group IPC); group Ⅳ propofol postconditioning (group PPC) and group V IPC + PPC. In group Ⅱ-Ⅳ the hepatic arteries and veins of middle and left lobes were occluded for 1 h followed by 4 h reperfusion. Ischemia of the liver was confirmed by the color of the liver turning from red to gray. In group Ⅲ and Ⅴ the livers were subjected to six episodes of 10 s ischemia at 10 s intervals at the end of 1 h ischemia before 4 h reperfusion. In group Ⅳ and V 0.5 % propofol 10 mg/kg was given iv at the end of ischemia followed by propofol infusion at 40 mg·g~(-1) ·h~(-1). Blood samples were taken at the end of 4 h reperfusion for determination of serum ALT activity. Mean-while liver specimens were taken for electron microscopic examination and determination of MDA content and SOD activity. Results I/R significantly increased serum ALT activity and MDA content in the liver and decreased liver SOD activity in group Ⅱ . The I/R-induced changes were significantly attenuated by propofol and/or ischemic postconditioning in group Ⅲ ,Ⅱ and Ⅴ . I/R significantly increased Bel-2 and Bax protein expression in the liver cells. Propofol and/or ischemic postconditioning increased Bel-2 protein expression further but decreased Bax protein expression in group Ⅲ , Ⅳ and Ⅴ as compared with group Ⅱ (group I/R).Electron microscopic examination showed that the pathologic changes induced by I/R were less severe in group Ⅲ, Ⅳ and Ⅴ than in group I/R. Conclusion Postconditioning with propofol and ischemia can reduce the hepatic I/R injury and the mechanism may be related to inhibition of lipid peroxidation and apoptosis, but the efficacy is the same as that of propofol postconditioning alone.
