Objective To explore the mechanism of plasma circulating miRNA-126 and miRNA-28-3p in diabetes mellitus (DM) patients,and to identify the related bioinformatics analysis.Methods Randomly selected 80 DM patients as the observation group and 80 non-DM patients as the control group.The plasma circulating miRNA-126 and miRNA-28-3p were analyzed by qRT-PCR,and its target genes,biological information,related lncRNA and circRNA were predicted.Results The circulating miRNA-126(0.115 0±0.014 4 vs.0.0019±0.000 6) and miRNA-28-3p(0.1386±0.01724 vs.0.000 6±0.000 05) levels in the observation group were significantly higher than those in the control group,and the differences were statistically significant (P<0.01).Pearson correlation coefficient of miRNA-126 and miRNA-28-3p was 0.433 5(P<0.01).ROC curve analysis of miRNA-126 and miRNA-28-3p showed that the differences of the area under curve were statistically significant between the two groups (P<0.01).Bioinformatics prediction showed that miRNA-126 and miRNA-28-3p may be involved in regulation of the insulin signaling pathway,insulin receptor signaling pathway,insulin/insulin growth factor signaling pathway,mitogen-activated protein kinase (MAPK) signaling pathway and angiogenesis.And it may be associated with a variety of lncRNA and circRNA.Conclusion Circulating miRNA-126 and miRNA-28-3p can be a novel biomarker of DM as it may participate in the mechanism of DM by regulating insulin and insulin growth factor related signaling pathways and be associated with some related lncRNA and circRNA.

Objective To evaluate the efficacy and toxicity of induction chemotherapy with nedaplatin and docetaxel plus concurrent intensity?modulated radiotherapy ( IMRT) with nedaplatin or cisplatin in the treatment of locally advanced nasopharyngeal carcinoma (NPC). Methods A total of 223 patients with pathologically diagnosed locally advanced NPC in five treatment centers from 2011 to 2012 were randomly divided into two groups. In the test group, one hundred and thirteen patients received two cycles of induction chemotherapy with docetaxel (65 mg/ m2 on day 1) and nedaplatin (80 mg/ m2 on day 1) plus concurrent IMRT with nedaplatin (40 mg/ m2 on day 1). In the control group, 110 patients received two cycles of induction chemotherapy with the same regimens plus concurrent IMRT with cisplatin (40 mg/ m2 on day 1). The survival rates were calculated with the Kaplan?Meier method and the differences in the survival rates between the two groups were analyzed using the log?rank test. Comparison of the incidence rates of adverse reactions between the two groups was made by the chi?square test. Results The follow?up rate was 99?? 1%.The response rates at 3 months after treatment in the two groups were both 100%. The 2?year local recurrence?free, regional recurrence?free, distant metastasis?free, and overall survival rates were 94?? 0%, 94?? 2%, 88?? 2%, and 90?? 3%, respectively, in the test group, versus 93?? 4%, 94?? 1%, 86?? 7%, and 87?? 3% in the control group ( P= 0?? 757、 0?? 478、 0?? 509、 0?? 413). The incidence rates and severity of leucopenia, neutropenia, and thrombocytopenia were significantly higher in the test group than in the control group ( P= 0?? 027 , 0?? 028 , 0?? 035 ) . The incidence rates and severity of hemoglobin reduction and nausea /vomiting were significantly lower in the test group than in the control group (P= 0?? 000,0?? 023). There were no significant differences in the incidence rates of mucositis and xerostomia between the two groups ( P=0?? 483,0?? 781). Conclusions The short?term efficacy of induction chemotherapy with nedaplatin and docetaxel plus concurrent IMRT with nedaplatin is similar to that with cisplatin in the treatment of locally advanced NPC. The mild gastrointestinal reactions can be tolerated by patients. However, the severe myelosuppression should be closely monitored during the treatment.

Objective To evaluate the effects of nitrous oxide inhalation on conscious sedation of patients during colonoscopy and analyze its risk factors. Methods From October 2016 to July 2017, a total of 154 patients undergoing colonoscopy were included in the study. The comfort level was rated using Modified Gloucester Comfort Scale ( MGCS). Factors affecting comfort level were analyzed by univariate analysis and multivariate Logistic regression, and then a comfort stratification predicting model was created. Results All 154 patients finished colonoscopy. The mean time of ideal anesthesia state was 195. 15 s. Among the 154 cases, 115 ( 74. 7%) were identified as comfort ( grade of MGCS from 1 to 3) and 39 (25. 3%) were rated as discomfort ( grade of MGCS from 4 to 5). Multivariate regression indicated that age ≥60 years ( P＝0. 000, OR＝1. 074, 95%CI: 1. 036-1. 114) and mild anxiety ( P＝0. 018, OR＝3. 338, 95%CI: 1. 227-9. 079) were associated with comfort level during colonoscopy.The established model with the age (X1) and mild anxiety (X2) was P＝eY/(1+eY), Y＝－3. 812+0. 071X1+1. 205X2(no anxiety was assigned 1, mild anxiety was assigned 2), and the area under the receiver operating characteristics curve was 0. 746 (95%CI: 0. 661-0. 830), which showed moderate predictive power of the final model. The model reached the highest predictive accuracy when the Yoden Index was 0. 838 with sensitivity of 50. 4% and specificity of 89. 7% for predicting comfort level of patients in conscious sedation status induced by nitrous oxide inhalation during colonoscopy. Conclusion Nitrous oxide can ease pain during colonoscopy, especially for patients over 60 years old and with anxiety. We can use it as an option according to actual circumstance in practice.
