AIM： To determine the thickness of the retinal ganglion cell-inner plexiform layer（GCIPL） and the retinal nerve fiber layer（RNFL） in patients with neuromyelitis optica（NMO）.METHODS： We conducted a cross-sectional study that included 30 NMO patients with a total of 60 eyes. Based on the presence or absence of optic neuritis（ON）, subjects were divided into either the NMO-ON group（30 eyes） or the NMO-ON contra group（10 eyes）. A detailed ophthalmologic examination was performed for each group; subsequently, the GCIPL and the RNFL were measured using highdefinition optical coherence tomography（OCT）. RESULTS： In the NMO-ON group, the mean GCIPL thickness was 69.28±21.12 μm, the minimum GCIPL thickness was 66.02±10.02 μm, and the RNFL thickness were 109.33±11.23, 110.47±3.10, 64.92±12.71 and 71.21±50.22 μm in the superior, inferior, temporal and nasal quadrants, respectively. In the NMO-ON contra group, the mean GCIPL thickness was 85.12±17.09 μm, the minimum GCIPL thickness was 25.39±25.1 μm, and the RNFL thicknesses were 148.33±23.22, 126.36±23.45, 82.21±22.30 and 83.36±31.28 μm in the superior, inferior, temporal and nasal quadrants, respectively. In the control group, the mean GCIPL thickness was 86.98±22.37 μm, the minimum GCIPL thickness was 85.28±10.75 μm, and the RNFL thicknesses were 150.22±22.73, 154.79±60.23, 82.33±7.01 and 85.62±13.81 μm in the superior, inferior, temporal and nasal quadrants, respectively. The GCIPL and RNFL were thinner in the NMO-ON contra group than in the control group（P〈0.05）; additionally, the RNFL was thinner in the inferior quadrant in the NMO-ON group than in the control group（P〈0.05）. Significant correlations were observed between the GCIPL and RNFL thickness measurements as well as between thickness measurements and the two visual field parameters of mean deviation（MD） and corrected pattern standard deviation（PSD） in the NMO-ON group（P〈0.05）. CONCLUSION： The thickness of the GCIPL and RNFL, as measured using OCT, may indicate optic

AIM: To study the effects of elemene (Ele) on proliferation and cell cycle of human lens epithelial cells 63 (HLE-B3) and the mechanisms of its signal transduction. METHODS: Recombinant human basic fibroblast growth factor (rhbFGF) was used to induce proliferation of HLE-B3 cells, which were incubated with 80mg/L Ele for 24 hours. The inhibitory effects of Ele on the proliferation of HLE-B3 cells were evaluated by MU method. The effect of Ele on HLE-B3 cell cycle was analyzed by flow cytometry (FCM). The expressions of protein kinase A (PKA) and protein kinase G (PKG) of HLE-B3 were also analyzed by FCM. RESULTS: Ele altered the cell cycle of HLE-B3 and effectively inhibited HLE-B3 cell proliferation induced by rhbFGF. Ele up-regulated PKA and down-regulated the expression of PKG in HLE-B3 cell. CONCLUSION: Ele inhibits HLE-B3 proliferation, making it an attractive potential agent in regimens to treat after-cataracts.

Peroxisomes are ubiquitous and dynamic eukaryotic organelles capable of altering their abun- dance in response to environmental and developmental cues, yet the regulatory mechanism of plant peroxisome division/proliferation is unclear. To identify transcriptional regulators of the peroxisome division factor gene PEX 11b, we performed a nuclear pull-clown experiment and identified Arabidopsis Forkhead- Associated Domain Protein 3 （FHA3） as a novel protein that binds to the promoter of PEX 11b. Our data supported the conclusion that, in contrast to the previously identified HY5 HOMOLOG （HYH） protein that promotes the transcription of PEX 11b, FHA3 is a negative regulator of PEX 11b expression and peroxisome division.

Flotation tests, contact angle measurements, infrared spectrum analyses, X-ray analyses and computer simulation were carried out in order to study the activation mechanism of lime-depressed pyrite with oxalic acid. The results show that the oxalic acid effectively eliminated the hydrophilic calcium film from the surface of pyrite. Therefore, the efficiency of pyrite flotation was also activated. The results indicate that after reacting with hydrophobic insoluble remainders on the surface of pyrite, oxalic acid can pro- duce hydrophilic compounds, such as CaC03, Ca（OH）2 and Fe（OH）3. As a consequence, a flesh pyrite layer was exposed and its flotation activated.
