[Summary] Long noncoding RNA( lncRNA) plays an important role in regulating the life activities, and its disordered expression is closely related to many diseases. Several studies have shown that lncRNA could modulate the endocrine metabolic processes at transcription, post-transcription, and the epigenetic modification levels, but the exact mechanism is still unclear. Further research needs to be done. This review will briefly describe the research progress of lncRNAs in endocrine and metabolic respects.

Ulcerative colitis (UC) is a subtype of inflammatory bowel disease. Its pathogenesis is not clear and the pathogenesis is complex. Moreover, it is recurrent and its healing is delayed. It is a kind of refractory disease. Its incidence and recurrence rate showed a trend of increasing year by year in our country at present. At the present stage, the main treatment focuses on glucocorticoids, aminosalicylic acid, immunosuppressor and biological agent. Although biological agent can greatly improve the efficacy, there are many problems in clinical treatment for a small amount of refractory patients. The comprehensive intervention combined with non-drug treatment should be performed, so as to achieve the curative effect. Fecal microbiota transplantation (FMT) has attracted people′s attention in recent years. It displays a certain therapeutic effect on the treatment of UC in the active stage, especially refractory recurrent UC. Therefore, the domestic and overseas FMT treatment are summarized in the paper.

Objective To understand the biological characteristicsand drug resistance of methicillin-resistant staphylococcus aureus (MRSA) isolated from neonatal clinic and the nose swabs of medical staff in the neonatal department.Methods Twenty-six strains of MRSA clinically isolated from the neonatal department and the nose swabs of medical staff in this department were collected and performed the multilocus sequence typing (MLST),spa typing, staphylococcus cassette chromosome mec (SCCmec) typing and pulsed-field gel electrophoresis (PFGE) typing.The Panton-Valentine leukocidin (PVL) gene was simultaneously detected.The antimicrobial susceptibility test of 14 antibacterial dugs was performed.Results Among 26 strains of MRSA,53.8% was isolated from sputum,2 strains were detected from the nase swab of medical staff.The MLST type had 5 types,ST59 accounted for 76.9%.The spa type had 8 types,t437 acoounted for 65.4%.the SCCmec type had only 2 types,20 strains were SCCmecⅣ(76.9%,20/26) and 4 strains(15.4%) were SCCmecV.In the PLV gene detection,the PVL positive rate was 15.4%.One strain of MRSA from the nose swabs of medical staff in the neonatal department was100% homologous with 1 strain from the patient by PFGE analysis.The drug susceptibility test results showed that all MRSA strains were 100% sensitive to antibacterial drugs of nitrofurantoin,quinupristin/dalfopristin,vancomycin and quinolone,while had higher resistance rates to tetracycline,erythromycin and clindamycin,which were above 50%.Conclusion In MRSA strains isolated from the neonatal department in this study,the most common clones were MRSA-ST59-SCCmecⅣ-t437.Erythromycin and clindamycin should not be preferred in the empiric treatment of newborn MRSA.

Objective To investigate the current status of self-efficacy and care ability among stroke patients′ family caregivers and explore the correlation between them. Method A total of 79 stroke patients and family caregivers were engaged in the investigation by demographical data questionnaires, general self-efficacy scale and questionnaire for assessing the comprehensive care-giving ability of stroke caregivers. Results The score on self-efficacy of the family caregiver was (27.16 ± 5.64) and the total score on care ability was (90.01 ± 16.57). There was a positive correlation between self-efficacy and care ability of family caregivers(P<0.05). Conclusions The self-efficacy and care ability of stroke patient′s family caregivers are at middle level. Their self-efficacy is positively correlated with their care ability. The nurses can improve the ability of daily caring of family caregivers by enhancing their self-efficacy.

a greater impact,which could account for some pathophysiological changes caused by catch-up growth.

Objective To investigate the statistical methods used in nursing papers for bachelor's degree. Method We collected 160 nursing theses for bachelor's degree in 2016 in our college and analyze the statistical methods. Results A total of 80 papers used statistical methods consisting of statistical table, statistical inference, single factor analysis, variance analysis and statistical description. Among them, the statistical methods in 66 papers (82.5%) were misused. About 139 misuses of statistical tables was found in papers, and about 23 misuses of statistical inference in papers, taking up 45.4%. Conclusions The nursing undergraduates are familiar with the application of statistical methods, but the methods tend to be simple and unitary. Therefore, it is a need to enhance their practice in using statistical methods.

Objective To analyze the application of clinicopathological features and LEF-1 in the diagnosis of solid pseudopapillary neoplasm of the pancreas (SPN).Methods Clinical and pathological data of 227 cases who were pathologically diagnosed as pancreatic SPN at Changhai Hospital from Jan 2000 to Dec 2015 were collected and analyzed.Immunochemical assay was used to detect the expression of LEF-1 in 132 cases of SPN, and the results were compared with β-catenin, which is most commonly used for diagnosing SPN.Results 81.9% of patients with SPN were female (186/227).Mean age at the onset was 34 years.Mean tumor size was 5.4 cm.48.5% tumors were localized in the pancreatic tail, and 33% in the head.46.3% tumors were cystic and solid, 42.3% were solid, and 11.4% were cystic.There were 2 cases of lymph node metastasis (0.9%), 15 cases of vascular tumor thrombus (6.6%), 14 cases of nerve invasion (6.2%), and 13 cases of adjacent organs invasion (5.7%) based on microscopic observations.Immunochemical analysis showed that 130 of 132 cases with SPN expressed LEF-1 with strong nuclear positivity, and the positivity rate was 98.5%.But no obvious expression of LEF-1 can be seen in normal pancreatic tissue and other pancreatic tumors.The specificity was 100%.The positivity of β-catenin expression in SPN was 96.6%(144/149), and β-catenin was positively expressed in only one case of acinar cell carcinoma.Tumors were completely removed by surgery in 165 cases, and the median follow-up was 51 months.By Oct 31, 2016, 162 patients (98.2%) survived, 5 had liver metastasis, and 1 had recurrence.Conclusions SPN is predominantly encountered in young female patients, and the clinical manifestations are not specific.LEF-1 can be used as a specific marker for the diagnosis and differentiation of SPN, which is more accurate than β-catenin.

Objective To explore the methods of the standardized management used in humanistic nursing care and to assess its effects.Methods Measures of the standardized management began to be used in such care at the hospital since January 2013.Questionnaires of patient satisfaction with nursing care for inpatients and those discharged were used to assess the effects of the standardized management measures periodically and synthetically.Results The patient satisfaction with humanistic nursing care keeps increasing year by year from 2013 to 201 5.The differences among three sets of data are statistically significant(P < 0.05 ).Conclusions Humanistic nursing care calls for promotion of standardized management.It is high time to build such a standardized management system at the hospitals.

ObjectiveTo observe the effect of resveratrol on the oxidative stress and antioxidant levels of different mitochondrial subpopulations in the skeletal muscle and insulin sensitivity of rats fed with high-fat diet.MethodsMale SD rats,aged 8 weeks,were divided into normal chow (NC) group,high-fat diet(HF) group,high-fat diet plus resveratrol ( HFR ) group.After intervention for 8 weeks,the impacts of resveratrol on oxidative stress levels and antioxidant enzymes activities in subsarcolemmal ( SS ) and intermyofibrillar ( IMF ) mitochondria from skeletal muscle as well as general and skeletal mascle insulin sensitivity were assessed.ResultsCompared with NC group, insulin sensitivity was significantly reduced while reactiveoxygenspecies (ROS)and malondialdehyde(MDA) levels in SS and IMF mitochondria increased in HF group ( all P＜0.01 ).In addition,antioxidant enzyme activities were significantly decreased in SS mitochondrial and increased in IMF mitochondrial ( both P ＜ 0.05 ).Compared with HF group,the insulin sensitivity in HFR group was significantly improved.Moreover,the activities of antioxidant enzymes in SS and IMF mitochondrial were increased,and the oxidative stress levels returned to normal ( P ＜ 0.05 ).ConclusionResveratrol notably improves the oxidative stress of different skeletal muscle mitochondrial subpopulations and insulin resistance in rats fed with high-fat diet.

Objective To investigate the effects of lentivirus-mediated heat shock protein 70 (HSP70) gene on calcium homeostasis and calcium channels of PC12 cells induced by ischemic and hypoxia and its mechanisms. Methods PC12 cells at logarithmic phase were collected, and they were divided into recombined lentiviral infection group [infected by lentivirus containing HSP70 and green fluorescent protein (GFP) fluorescin gene], lentivirus control group (infected by lentivirus containing GFP without HSP70 gene) and non-infection group. PC12 cells were subjected ischemia/hypoxia for 4, 8, 12, 24 hours, and the cell activity was determined by methylthiazolyl tetrazolium (MTT) assay test inorder to determine the best time for ischemia/hypoxia. The mRNA expressions of HSP70, muscle/endoplasmic reticulum Ca2+-ATP isoforms (SERCA2a, SERCA2b), ryanodine receptor 2 (RyR2), and inositol 1,4,5-triphosphate receptor 1 (IP3R1) were determined by real-time quantitative reverse transcription-polymerase chain reaction (RT-qPCR), and the protein expressions of HSP70, SERCA, and IP3R were determined by Western Blot at 8 hours after ischemic/hypoxia. Flow cytometry was used to determine the levels of intracellular reactive oxygen (ROS) and intracellular Ca2+ ([Ca2+]i). Results With the prolongation of time of ischemia/hypoxia, the cell viability in all groups showed an increase followed by a weakening, and peaked at 8 hours. The cell viability at 8 hours in lentiviral infection group was significantly higher than that of the non-infection group and lentivirus control group [A value (×10-2): 20.3±2.2 vs. 14.1±2.1, 15.0±1.6, both P < 0.01], the mRNA and protein expressions of HSP70 and SERCA in lentiviral infection group were significantly increased [HSP70 mRNA (2-ΔΔCt ): 0.785±0.018 vs. 0.428±0.019, 0.423±0.023; HSP70 protein (gray value): 2.72±0.20 vs. 1.56±0.36, 1.63±0.41; SERCA2a mRNA (2-ΔΔCt ): 0.971±0.037 vs. 0.367±0.014, 0.347±0.012; SERCA2b mRNA (2-ΔΔCt ): 8.869±0.162 vs. 3.015±0.091, 2.941±0.091; SERCA protein (gray value): 2.84±0.18 vs. 1.48±0.26, 1.52±0.29], and IP3R2 mRNA and protein expressions were significantly declined [IP3R2 mRNA (2-ΔΔCt ): 0.183±0.020 vs. 0.439±0.020, 0.433±0.040; IP3R2 protein (gray value): 1.15±0.12 vs. 1.91±0.20, 1.83±0.19], with statistically significant differences (all P < 0.01); no significant difference in RyR mRNA was found [2-ΔΔCt (×10-3): 1.97±0.63 vs. 2.02±0.22, 2.01±0.09, both P > 0.05]; the relative fluorescence intensity of ROS and [Ca2+]i in lentiviral infection group was significantly reduced (ROS: 30.54±1.23 vs. 58.03±1.97, 57.72±2.35; [Ca2+]i: 34.50±2.05 vs. 48.20±3.02, 46.80±2.75, all P < 0.01]. Conclusion Exogenous HSP70 can maintain calcium homeostasis in the endoplasmic reticulum of PC12 cells, affect the Ca2+ channel protein regulated by calcium channel IP3R and calcium pump SERCA, which may cause hypoxia/ischemia intracellular injury.
