Long non-coding RNA plays an increasingly important role in transcriptional, post-transcriptional and epigenetic levels. In ischemic heart disease, most studies on long non-coding RNA focused on myocardial infarction, hypertrophy and fibrosis, and a few of reports directly focused on the pathological process of myocardial reperfusion injury. Thus, the purpose of this review is to introduce the processes of long non-coding RNA in myocardial reperfusion injury field, aiming to provide a novel research and theraputic method for exploring the mechanism and molecular regulation network involed with reperfusion injury.

Objective To explore the effect of enteral nutrition applied to bowel preparation of diabetes patients before electronic colonoscopy. Methods A total of 172 diabetes patients were randomly allocated to the experimental group and the control group with 86 patients in each group. The experimental groups executed no dietary restriction within 3 days before the examination, and received Ensure 1h before colonoscopy. However,the control group was given low residue diet within 3 days before the examination, and received no Ensure before colonoscopy. The enteral cleanness and incidence of hypoglycemic reaction, abdominal pain and horror was compared between the two groups. Results 72 cases(83.72%) of the experimental group and 70 cases (81.40%) of the control group had better enteral cleanness, and there was no statistical difference in intestinal cleanness between the two groups. In the experimental group the incidence of hypoglycemic reaction, abdominal pain, horror was significantly lower than those in the control group. Conclusions Bowel preparation with unrestricted diet and ingested ensure before colonoscopy can not only ensure intestinal cleanness but also enhance endurance of colonoscopy.

Objective To identify and analyze the homology of Ochrobactrum isolated from clinical blood samples of children.Methods The 26 strains of Ochrobactrum anthropi were identified by Vitek 2 Compact and test strips of API 20 NE bacterial identification system.The biochemical phenotypes were identified by manual tests.The 16S rRNA and recA gene were amplified by PCR and sequenced.The drug sensitivity tests of Ochrobactrum anthropi were performed by Vitek 2 Compact and matched GN13 card.The homology was analyzed by pulsed field gel electrophoresis.Results Based on the identification of the instruments and the manual tests for biochemical phenotype,all the 26 experimental strains were Ochrobactrum anthropi.The results of sequencing for 16S rRNA and recA gene amplification products showed 25 strains were Pseudochrobactrum saccharolyticum and the other 1 was O.grignonensein.Drug sensitivity analysis showed that the all the 26 strains were resistant to aztreonam,but the sensitive rates to quinolones,aminoglycosides,trimethoprim sulfamethoxazole,four generation of cephalosporins and the antibiotics compound of piperacillin/tazobactam were all more than 80％.Pulsed field gel electrophoresis analysis showed that the 25 strains were highly homologous with differences of only 1 to 3 bands in fingerprint profiles.Conclusion Based on the biochemical phenotype and the sequencing of 16S rRNA and recA gene,the Ochrobactrum-like bacteria could be identified to the level of species.The highly homologous strains of Pseudochrobactrum saccharolyticum may be sourced from a clustered infection.

Objective To evaluate the diagnostic value of thick-slab single-shot turbo spin-echo (SSTSE)T2 ?-weighted sequence in magnetic resonance fetography (MRF)for fetal abnormalities.Methods 328 of 1 990 pregnant women with the diagnosis of fetal congenital defects on prenatal ultrasound screening or chromosome examination were randomly selected,and 338 fetuses were ob-tained.These fetuses were scanned by conventional magnetic resonance imaging (MRI)and MRF.The diagnostic results from the two MR methods were compared.Results Six hundred and twenty-four lesions were detected by MRF.The primary diagnosis based on conventional MRI was changed for 14 lesions (2.2%).New findings were identified for 48 fetal lesions (8.4%)and 66 ma-ternal lesions.However,78 fetal lesions could not to be identified by MRF.MRF could increase the diagnostic confidence for fetal lesions with high water content (56.1% of the lesions).Conclusion MRF can yield more precise information for fetal extremities, fluid-filled cavities,pathological hydrops and cystic lesions.As an additional aid to the conventional multi-slice T2-weighted se-quence.
