In order to investigate the effect of Polo-like kinase-1 (Plk1) depletion on cell cycle progression and cell growth in lung cancer cells, a recombinant plasmid containing antisense RNA targeting Plk1 (pcDNA3-Plk1) was transfected into A549 cells by lipofectine. RT-PCR and Western-blot were used to detect the Plk1 gene expression. Cell proliferation was evaluated by direct cell counting and bromodeoxyuridine (BrdU) labeling. Cell cycle distribution and apoptosis were examined by flow cytometry, and the inhibition rate (IR) by vinorebline (NVB) was determined by MTT assay. The results showed that after transfection of pcDNA3-Plk1 into A549 cells, the expression levels of Plk1 mRNA and protein were greatly decreased. In pcDNA3-Plk1 transfected groups, abnormal morphological changes of cells and growth inhibition were observed, and the BrdU labeling index was significantly lower than in the control groups (P<0.05). Cells in pcDNA3-Plk1 transfected groups were arresed in G2/M phase and apoptosis was detectable 72 h post transfection. IR induced by vinorebline in pcDNA3-Plk1 transfected groups was significantly higher than in other groups. These data suggested that antisense RNA targeting Plk1 could suppress the Plk1 expression, and therefore, significantly inhibit cell proliferation and induce cell cycle arrest and apoptosis. Moreover, it sensitized lung cancer cells to chemotherapy.

· AlM:To analyze the association between the macular thickness and emmetropic, low myopic, moderate myopic and highly myopic eyes.
·METHODS:The 276 teenagers (276 eyes) between 18~28 years treated in our hospital from January, 2013 to May, 2014 were selected, whose corrective visual acuity was≥1.0 and intraocular preasure was ≤21mmHg and who were willing to participate in this research.Forty-nine emmetropic, 72 low myopic, 104 moderate myopic and 51 highly myopic eyes were measured by optical coherence tomography ( OCT ) to detect the central subfield thickness, bitamporal, superior, lateral and inferior region thickness of inner and outer region, average thickness of retinal macula, foveal thickness and retinal volume.The thickness of different parts of macula lutea was measured and statistically compared among emmetropic, low myopic, moderate myopic and highly myopic eyes.
· RESULTS: The central subfield thickness of emmetropic, low myopic, moderate myopic and highly myopic eyes were (225.38±20.97), (230.97±19.15), (227.01±16.92), (231.91 ±18.97 )μm. The average thickness of retinal macula, of emmetropic, low myopic, moderate myopic and highly myopic eyes were (280.92±12.71), (278.15± 11.90), (270.05±12.07), (267.93±11.08) μm.There were no significant differences of center thickness (F=1.253, P=0.291) and central subfield thickness ( F=1.034, P=0.378) between emmetropic, low myopic, moderate myopic and highly myopic eyes.The macular thickness of inner and outer region in moderate myopic eyes was significantly less than that in emmetropic eyes, and there was significant difference (P<0.05).Comparison between low myopic, moderate myopic and highly myopic eyes was carried out and macular thickness of all regions of inner and outer region in moderate myopic group was significantly increased, and there was significant difference (P<0.05).There was no significant difference when compared with the macular thickness of inner and outer region of the highly myopic group (P>0.05).
· CONCLUSlON: ln low myopic eyes of teenagers, the center macular thickness do not become thinner. However, the macular thickness of inner and outer region is thinner than that of emmetropic eyes.Furthermore, with the increase of the degree of the myopia, the amount of macular thinner gradually decreases from outer region to inner region.

This study was aimed to explore the clinical efficiency of modified Xiao-Y ao (XY) powder and acupuncture in the treatment of diarrhea-predominant irritable bowel syndrome (D-IBS). A total of 90 D-IBS patients were randomly divided into the treatment group and control group, with 45 patients in each group. Patients in the treatment group received acupuncture combined with modified XY powder. Patients in the control group received oral administration of montmorillonite powder, compound glutamine enteric-coated capsules, compound azintamide enteric coated tablet. Four weeks were one treatment course. After two treatment courses, the pretreatment and posttreatment symptom score, the score of Hamilton Depression Rating Scale (HAMD)/(HAMA), and the overall efficacy were compared. The results showed that compared with pretreatment, clinical symptoms were improved in varying degrees after treatment in both groups (P < 0.05 or P < 0.01). HAMD and HAMA were significantly decreased (P < 0.05). The treatment group had obvious advantages compared to the control group (P < 0.05). The overall efficacy of the treatment group was 91.11%, which was significantly higher than the control group of 68.89%(P < 0.05). It was concluded that modified XY powder and acupuncture can quickly relieve gastrointestinal symptoms, improve anxiety and depression. It is an effective treatment method for D-IBS.
