Objective:The significant role of long non-coding RNAs (lncRNAs) in early diagnosis and predicting prognosis has been recognized in various cancers recently.However,the prognostic value of HOXA transcript at the distal tip (HOTTIP),a vital lncRNA in tumorigenesis,remains unclear.In this study,we evaluated its prognostic value by analyzing the correlation of HOTTIP expression with overall survival (OS),lymph node metastasis (LNM) and distant metastasis (DM) in different cancer types by meta-analysis.Methods:We performed a systematic search in PUBMED,MEDLINE,Web of Science and Cochrane Library update to November of 2016.A total of 604 patients from 6 studies were included in final analysis and went through a quantitative meta-analysis by Review manager 5.3.Results:We demonstrated that high expression of HOTTIP had a significant correlation with poor OS (hazard ratio [HR] =2.37,95％ confidence interval [CI] =1.81-3.10,p＜0.001),high LNM rate (odds ratio [OR]=2.29,95％CI=1.54-3.40,p＜0.001) as well as more DM occurrence (OR=3.30,95％CI=1.78-6.12,p＜0.001).Conclusion:Our results indicated that long non-coding RNA HOTTIP may serve as a potential prognostic biomarker in cancer progression.

In this experiment, the HPLC specific chromatogram was adopted, with Agilent Extend-C18 (4.6 mm x 250 mm, 5 microm) as the chromatographic column, and 0.5 per thousand trifluoroacetic acid and acetonitrile as the mobile phase for gradient elution, so as to establish specific chromatograms for drug pair of Schizonepetae Herba and Saposhnikoviae Radix from different producing area, identify 12 common characteristic peaks, and obtain the comparison specific chromatography of drug pair of Schizonepetae Herba and Saposhnikoviae Radix. The method is simple, accurate and highly reproducible, and thus can be used as the basis for the quality control of the drug pair.

ITS2 sequence was used as a barcode to identify Viticis Fructus and its adulterants. The study collected 46 samples include Viticis Fructus and its adulterants. The sequences were obtained by extracting DNA, amplification, sequencing bi-direstionlly, and then assembling with CodonCode Aligner. To identify Viticis Fructus and its adulterants, the study used the methods of computing the genetic distances by Kimura 2-Parameter (K2P) model and constructing the Neighbor-joining (NJ) phylogenetic trees using MEGA5.0. The results showed that the maximum inter-specific K2P distance of Viticis Fructus was less than the minimum inter-specific K2P distance of Viticis Fructus and its adulterants and the NJ tree indicated that the Viticis Fructus and its adulterants could be distinguished clearly. Therefore, using ITS2 barcode can distinguished Viticis Fructus and its adulterants accurately.

Background Research showed that exposure of 530 nm monochromatic light can induce myopia in animal,and retinal Müller cells participate in the formation of myopia.However,the effect and mechanism of retinal Müller cells during the formation of monochromatic light induced-myopia is below understood.Objective This study was to investigate biologic characteristics of rat retina Müller cells and the expression of cell factors in Müller cells after being illuminated by the 530 nm monochromatic light,and discuss the role of the retina Müller cells in myopia induced by monochromatic light.Methods Immortalized rat retinal Müller cells were cultured with DMEM containing 10％ fetal bovine serum in a self-made cell incubator with monochromatic light by adjusting luminance of 530 nm LED source.The cells were exposed to 125,250 and 500 lx luminance respectively for 6,12 and 24 hours,and the cells without light-irradiation were used as control.The growth of the cells under the different light time and different illuminations was described by MTT as the absorbance at the wavelength 570 nm (A570),and cell cycle analysis of Müller cells was performed by flow cytometry 48 hours after cultured,and the expression of transforming growth factor-beta 1 (TGF-β1),tyrosine hydroxylase(TH),inducible nitric oxide synthase(iNOS) and basic fibroblast growth factor(bFGF)in the cells were detected by reverse transcription PCR(RT-PCR),respectively.Results The Müller cells were uniform in size with polygonal shape and defined edges.No statistically significant difference was found in the A570 value in the cells of the 125 lx and 250 lx illuminated groups compared with the control group in various time points(P＞0.05).However,significant lowing was seen in the A570 value in the cells of the 500 lx illuminating for 12 hours and 24 hours in comparison with the control group (P =0.013,0.001).Compared with the control group,the ratio of the number between G2 and G1 phase was not significantly declined in 125 lx,250 lx illuminating for 48 hours (P =0.073,0.330),and the ratio in the 500 lx illuminating group was significantly lower than those in the 250 lx illuminated group and the control group (P =0.028,0.038).RT-PCR revealed that the expression of TGF-β1 mRNA in the cells was higher in the 250 lx illuminated group than that of the 500 lx illuminated group (P=0.006).The expression of iNOS mRNA was gradually upregulated in the 250 lx illuminated group compared with the control group (P =0.001),but that in the 500 lx illuminated group was downregulated (P =0.000).The expression of bFGF mRNA was raised in the 125 lx and 250 lx groups but reduced in the 500 lx group when compared with the control group(P=0.002,0.000,0.005).Also,the expression of TH mRNA was significantly increased in the 250 lx group(P=0.000),but decreased in the 500 lx group(P=0.000,P=0.001).Conclusions The monochromatic light of 530 nm can inhibit the growth of rat Müller cells and downregulate the expression of myopia-related cell factors and therefore exert effect in the formation of myopia.

OBJECTIVETo study the effect of coixenolide on Foxp3+ CD4+ CD25+ regulatory T cells (Treg) in collagen induced arthritis (CIA) mice, and to explore its possible mechanism for treating rheumatiol arthritis.

METHODSFive mice were recruited as a normal control group from 25 mice, and the rest 20 were used in CIA modeling. After successful modeling they were randomly divided in the model control group and the coixenolide group, 10 in each group. Coixenolide injection at 25 mL/kg was intraperitoneally injected to mice in the coixenolide group, while normal saline at 25 mL/kg was intraperitoneally injected to mice in the normal control group and the model control group. The injection lasted for 21 days. Scoring for CIA was performed after injection and arthritis index was calculated. The peripheral blood Foxp3+ CD4+ CD25+ Treg ratio was determined by flow cytometry (FCM).

RESULTSCompared with the normal control group, the arthritis index obviously increased in the model control group (P < 0.01). The arthritis index obviously decreased more in the coixenolide group than in the model control group (P < 0.01). Foxp3+ CD4+ CD25+ Treg levels obviously decreased more in the model control group than in the normal control group (P < 0.01 ). Foxp3+ CD4+ CD25+ Treg levels obviously increased more in the coixenolide control group than in the model control group (P < 0.01).

CONCLUSIONCoixenolide could up-regulate Foxp3+ CD4+ CD25+ Treg ratios in CIA mice, which might play certain immunoregulation roles in the incidence of CIA.
