Heritable changes in gene expression are regarded as epigenetics,which do not involve coding sequence modifications.The study of ophthalmology epigenetics is a rapidly growing area in biomedical research.Epigenetic mechanisms principally include DNA methylation,histone modification,chromatin remodeling and noncoding RNA.Aberrant DNA methylation and histone modification are linked to a number of age-related disorders,such as cancer,autoimmune and others.In recent years,the modulations of epigenetic changes on the pathogenesis of eye disorders and their roles in therapeutic interventions are drawing more and more attention,and these studies deepen the understanding of relevant diseases.Since the epigenetic alterations are reversible,modifying epigenetic marks contributing to eye diseases provide a new approach to the development of disease prevention,diagnosis and therapies.Herein we discuss the roles of epigenetic changes in eye disease development,hoping that ophthalmologists and researchers pay attention to these researching cues in pathogenesis of eye disorders caused by genetic expression alterations in response to environmental changes,importantly,to the implication for relevant eye disease therapy and prevention.

OBJECTIVE:To systematically review the cost-effectiveness of insulin degludec(IDeg)in the treatment of type 1 diabetes mellitus(T1DM)and type 2 diabetes mellitus(T2DM). METHODS:A systematic review of literatures was conducted via PubMed,EMBase,The Cochrane Library,CNKI,Wanfang Data,VIP,IDF,ISPOR,ADA and EASD from the inception to Janu-ary 2016,to identify pharmacoeconomics evaluation literatures and non-economic studies related to IDeg in the treatment of T1DM and T2DM,compared with other basic insulin [insulin glargine(IGlar),insulin detemir(IDet),neutral protamine hagedom insulin (NPH)]. RESULTS:A total of 8 studies were included and all of them were carried out in European countries. In the short-term (one year),IDeg was more economical when compared with other basic insulin in patients with T1DM. The studies related to the long-term treatment of T1DM demonstrated different conclusions,but most of studies came to a conclusion that IDeg had good cost-effectiveness. For patients with T2DM,all of the studies demonstrated that IDeg was cost-effectiveness compared with IGlar. CONCLUSIONS:Compared with other basic insulin,IDeg can improve therapeutic efficacy and the quality of life,as well as re-duce the cost of ADR as hypoglycaemia. IDeg is a dominant or cost-effective treatment opinion.

Objective There are quite a few chemotherapeutic adjuvants for the treatment of advanced oral squamous cell carcinoma, but all have their adverse effects. This study was to evaluate the efficacy and adverse effects of the induction chemotherapy of S?1 plus docetaxel and cisplatin in the treatment of advanced oral squamous cell carcinoma. Methods Totally, 84 patients with advanced oral squamous cell carcinoma were randomly divided into an observation and a control group of equal number, the former trea?ted with S?1 plus docetaxel and cisplatin and the latter with 5?fluorouracil, docetaxel and cisplatinand, both for two cycles ( 1 cycle =21 d) . Then the effects and adverse events were evaluated and compared between the two groups of patients. Results No statistically significant differences were observed in the response rate between the observation and control groups of patients (76.19% vs 73.81%, P>0.05). The incidence rates of adverse events, such as nausea and vomiting (66.67% vs 88.10%, P<0.05) and phlebitis (0 vs 19.05%, P<0.05) , were remarkably lower in the former than in the latter group. Conclusion S?1 plus docetaxel and cisplatin is a reli?able induction chemotherapy with few adverse effects in the treatment of advanced oral squamous cell carcinoma.

RNA-seq can help us quickly obtain the whole transcriptome sequences of species under different conditions. Many Unigenes that are assembled by raw reads always do not contain complete open reading frame (ORF). In addition, it also has some redundancy in transcriptome library. Some Unigenes in the library, although belong to one transcript, cannot be assembled without overlapping. We found five incomplete Unigenes annotated ammonium transporter (AMT) from Salicornia europaea transcriptome, in which two Unigenes (Uni4 and Uni5) had identical expression patterns across four transcriptomes. The two Unigenes may come from one transcript. Analyzing the Unigene position of transcript by NCBI blastx, we found that Uni4 and Uni5 respectively located in 5' end and 3' end compared with the reference transcript, and an unknown gap of 120 bp may exist in a hypothetic transcript to which Uni4 and Uni5 both belong. To verify the hypothesis, single forward primer and single reverse primers were respectively designed on Uni4 and Uni5, and a fragment with about 800 bp was generated by PCR. Then it was sequenced and aligned with Uni4 and Uni5. Finally, we assembled a sequence with 1 667 bp, which contains a complete ORF (1 482 bp, coding 494 amino acids). It belongs to amt1 subfamily and was named Seamt1 via the phylogenetic analysis. It was pointed by bioinformatics tools that SeAMT1 protein conformed to the AMT characteristics of other species. This work clustered expression pattern to explore the Unigenes of one transcript, and the feasibility of this method was validated through the other two groups of Unigenes. The handy method will benefit extension and assembling of Unigene in transcriptome, it also helps achieve the complete ORF and gene function.

Objective To systematically evaluate the clinical efficacy and safety of Fufang-Danshen Injection (FD) in the treatment of unstable angina pectoris(UAP). Methods Randomized controlled trials (RCTs) and quasi-RCTs regarding FD in the treatment of UAP were collected through comprehensive searches of China National Knowledge Infrastructure(CNKI), Chinese Scientific Journals Database(VIP), Wan fang Database, Chinese Biomedical Literature Database(CBM), PubMed, Embase and Cochrane Library from January 1979 to December 2013. Two reviewers independently assessed the quality of the included studies by the Cochrane risk of bias, and extracted the information from the included studies. Meta-analysis was conducted with the software Review Manager 5.2. Results A total of 13 studies with 1156 participants were included. In the meta-analysis, ①the total effective rate of UAP:in term of FD+conventional therapy with western medicine(WM)vsWM, the difference between two groups was statistically significant [RR=1.32, 95%CI(1.21, 1.43), P<0.01]; FD+low molecular weight heparin+WM vs WM, difference between two groups was also statistically significant [RR=1.29, 95% CI(1.17, 1.42), P<0.01], which indicated that the efficacy of experimental group was higher than the control group. Other interventions, such as FD+WM vs low molecular weight heparin+WM and FD vs WM, there was no significant difference between two groups. ②the total effective rate of ECG:in term of FD+WM vs WM, the difference between two groups was statistically significant [RR=1.34, 95%CI (1.14, 1.57), P<0.01]; in term of FD vs WM, difference between two groups was statistically significant [RR=1.49, 95%CI(1.13, 1.96), P<0.01], which indicated that experimental group can effectively improve the total effective rate of ECG. ③ frequency of angina attacks:in term of FD+WM vs WM, the difference between two groups was statistically significant [MD=1.07, 95%CI(0.48, 1.66), P<0.01]. No differences between groups existed in other analysis. ④ adverse drug reactions(ADRs):4 articles cleared that there was no ADRs in the studies, 4 studies reported ADRs, which represented headache, nausea, flushing and so on. There were 9 cases in the experimental group, and 9 in control group. Conclusion Based on the meta-analysis, FD was effective and relatively safe for the treatment of UAP in clinical. However, since the articles enrolled in the study were not in high quality, more qualified studies should be conducted for the further assessment of efficacy and safety of FD for UAP.
