The diagnostic and prognostic significance of long non-coding RNA CRNDE in pan-cancer based on TCGA, GEO and comprehensive meta-analysis.

BACKGROUND: Accumulating evidence has confirmed that CRNDE is significantly expressed in various cancers, suggesting that it may be a potential biomarker for cancer. However, its diagnostic and prognostic values of CRNDE in cancer are not completely clear. Therefore, we conduct a comprehensive study on CRNDE in cancer. MATERIALS AND METHODS: CRNDE expression data were downloaded from The Cancer Genome Atlas (TCGA). Microarray data were derived from the Gene Expression Omnibus (GEO) database to validate its differential expression. Furthermore, the receiver operator characteristic curve (ROC) and Kaplan-Meier survival analysis were used to evaluate the diagnostic and prognostic values of CRNDE in cancer, respectively. Finally, we carried out a meta-analysis to comprehensively evaluate the diagnostic and prognostic values of CRNDE in cancer. RESULTS: In TCGA database, CRNDE was overexpressed in nine types of cancer, among which polymorphic glioblastoma and colonic adenocarcinoma are the most highly expressed. The area under curves (AUC) of nine cancer types ranged from 0.855 to 0.984. Additionally, the high expression level of CRNDE was significantly associated with poor overall survival only in hepatocellular carcinoma (p = 0.032) among the nine cancers in the Kaplan-Meier survival analysis. Finally, the results of the meta-analysis on the literatures showed that the pooled sensitivity, specificity, summary receiver operator characteristic curve (SROC), and the overall hazard ratio of CRNDE in cancers were 0.77 (95% CI: 0.71-0.82), 0.90 (95% CI: 0.82-0.95), 0.87 (95% CI: 0.84-0.90), and 1.66 (95% CI: 1.37-2.01), respectively. CONCLUSION: CRNDE could be a potential biomarker for cancer diagnosis and prognosis.

Microorganism on Hands of Nurses During Intravenous Infusion / 中华医院感染学杂志

OBJECTIVE To investigate the microorganisms on the hands of nurses who are doing the intravenous infusion.METHODS Sampled the hands of nurses during the procedure of intravenous infusion randomly,and then sampled after monitoring the nurses washing their hands by the six steps hand-cleaning technique.Then cultured the samples and did the identification of bacteria.The distribution of microorganism on nurses' hands was analyzed.RESULTS During the procedure of intravenous infusion,before and after the intervention the microorganisms on the nurses' hands had evident difference and with the statistic meanings.CONCLUSIONS The handwashing compliance among nurses before working in our hospital is poor,and the hand hygiene status during the nursing procedure needs to be improved.

Disinfection and Management of Oral Apparatus / 中华医院感染学杂志

OBJECTIVE To search for available mode of oral apparatus′s disinfection and management.METHODS To use new ways of oral apparatus′s disinfection and management that are enhancement of recognition,normal disinfecting procedure,available disinfection room,enhancement of management,new management system,building digitizing management and so on.RESULTS To build effective system and decrease abrasion and uselessness of oral apparatus.CONCLUSIONS Effective disinfection and management are very important for prevention of the cross infection and ensuring of daily use of oral apparatus.

Prophylactic Application of Antibiotics in Aseptic Operation: An Investigation Analysis / 中华医院感染学杂志

OBJECTIVE To study the usage of antibiotics in aseptic operation,and strengthen the management of antibiotics usage. METHODS We investgated the usage of antibiotics in aseptic operation retrospectively,then statistically analyzed. RESULTS Among all the 347 cases,343 cases were used for prophylaxis,the usage rate was 98.85%.The mean time of antibiotic therapy was 7.22 days.90.96% of the patients were treated with antibiotics for 3 days or more,53.35% of the patients were treated beyond 7 days.Ninety one patients were given antibiotics 0.5-2 hours before the operation(26.53%).There were 7 kinds of drugs used in the operation,the cephalosporin class accounted for 70.26%,moreover was third generation cephalosporin. CONCLUSIONS The prophylactic application of antibiotics in the aseptic surgery has some unreasonable phenomenon and must be strengthened.Training the doctor to use the antibiotics reasonably,and the effective surveillance management mechanism be established.
