Objective:To explore the effect and mechanism of lncRNA SBF2-AS1 on glioma cell proliferation, apoptosis and radiosensitivity.Methods:Real-time quantitative polymerase chain reaction (RT-qPCR) was used to detect the mRNA expression levels of SBF2-AS1, miR-1287-5p and FSCN1 in normal human brain glial cell HEB and glioma cell lines, including LN18, SW1088, Hs683, and western blot method was used to detect the expression level of FSCN1 protein in cells. Glioma cells including LN18 and SW1088 were taken as the research object. After SBF2-AS1 small interfering RNA, miR-1287-5p mimics, FSCN1 small interfering RNA were transfected into LN18 cells, CCK-8 was used to detect cell proliferation, flow cytometry was used to detect cell apoptosis, clone formation experiment was used to detect cell radiosensitivity, Western blot was used to detect the protein expressions of cyclin D1, cleaved-caspase 3 and phosphorylated histone 2A variant phosphorylated histone (γ-H2AX). Dual luciferase reporter gene experiments verified the regulatory relationship between SBF2-AS1 and miR-1287-5p, as well as miR-1287-5p and FSCN1.Results:Compared with HEB cells, the expression level of SBF2-AS1 and the expression levels of FSCN1 mRNA and protein in glioma cell line LN18, SW1088 and Hs683 were significantly increased ( P<0.05), and the expression level of miR-1287-5p was significantly reduced ( P<0.05). After down-regulating SBF2-AS1, up-regulating miR-1287-5p or down-regulating FSCN1 expression, LN18 and SW1088 cells activity and cyclin D1 protein expression were significantly reduced ( P<0.05), the apoptosis rate and cleared-caspase-3 protein expression were significantly increased ( P<0.05), the survival score was significantly reduced ( P<0.05), and the expression ofγ-H2AX protein was significantly increased ( P<0.05). The results of dual luciferase reporter gene assay showed that the luciferase activity of LN18 and SW1088 cells co-transfected with miR-1287-5p mimics and SBF2-AS1-WT or FSCN1-WT was lower than that of co-transfected miR-NC and SBF2-AS1-WT or FSCN1-WT in LN18 and SW1088 cells ( P<0.001), while the luciferase activity of LN18 and SW1088 cells co-transfected with miR-1287-5p mimics and SBF2-AS1-MUT or FSCN1-MUT was not significantly different from that of miR-NC transfected with SBF2-AS1-MUT or FSCN1-MUT ( P>0.05). The expression level of miR-1287-5p in LN18 and SW1088 cells in si-SBF2-AS1 group was higher than that in si-NC group ( P<0.05), and the expression level of miR-1287-5p in LN18 and SW1088 cells in pcDNA-SBF2-AS1 group was higher than that in si-NC group ( P<0.05), but lower than that of pcDNA-NC group ( P<0.05). The protein expression level of FSCN1 in LN18 and SW1088 cells in the miR-1287-5p group was significantly lower than that in the miR-NC group ( P<0.05), and the protein expression level of FSCN1 in LN18 and SW1088 cells in the anti-miR-1287-5p group was significantly higher than that in the anti-miR-NC group ( P<0.05). When miR-1287-5p and SBF2-AS1 were down-regulated simultaneously or FSCN1 was up-regulated while SBF2-AS1 was down-regulated simultaneously, the proliferation and cyclin D1 protein expression of LN18 and SW1088cells were significantly increased ( P<0.001), the apoptosis rate and cleared-caspase-3 protein expression were significantly reduced ( P<0.001), the survival score was significantly increased ( P<0.001), and the expression of γ-H2AX protein was significantly reduced ( P<0.001). Conclusion:SBF2-AS1 highly expresses in glioma cells, down-regulation of SBF2-AS1 expression can inhibit the proliferation of glioma cells, promote apoptosis, and enhance cell radiosensitivity by regulating the miR-1287-5p/FSCN1 axis.

The adjacent anatomy of the pelvis is complicated, with digestive, urinary, reproductive and other organs as well as important blood vessels and nerves. Therefore, accurate resection of pelvic tumors and precise reconstruction of defects after resection are extremely difficult. The development of medical 3D printing technology provides new ideas for precise resection and personalized reconstruction of pelvic tumors. The “triune” application of 3D printing personalized lesion model, osteotomy guide plate and reconstruction prosthesis in pelvic tumor limb salvage reconstruction treatment has achieved good clinical results. However, the current lack of normative guidance standards such as preparation and application of 3D printing personalized lesion model, osteotomy guide plate and reconstruction prosthesis restricts its promotion and application. The formulation of this consensus provides normative guidance for 3D printing personalized pelvic tumor limb salvage reconstruction treatment.

Objective:To evaluate the effect of transitional care on the quality of life of patients with pancreatitis.Methods:We searched the following databases such as PubMed, Web of Science, Cochrane Library, CNKI, CBM, and WanFang Data electronically. Other sources as applying were also retrieved. Comprehensive collection of continuing care on the quality of life in patients with pancreatitis related research. According to the evaluation method of Cochrane system, the quality evaluation and data extraction were carried out, and the RevMan 5.3 software was used for Meta analysis.Results:A total of 21 randomized controlled trials involving 1 818 patients (910/908) were included. SF-36 health survey scale, analysis of 8 Meta subgroups showed that all groups P<0.05, and the combined effect was statistically significant. The results of the intervention with telephone as the main outcome indicator were: maintaining a regular lifestyle [weight mean difference ( WMD) value was 4.33, 95% confidence interval ( CI)2.52-7.44, P<0.01], quitting smoking and drinking ( WMD value was 5.95, 95% CI 3.69-9.59, P<0.01), maintaining a healthy diet ( WMD value was 8.62, 95% CI 5.07-9.59, P<0.01). Continuous nursing based on telephone intervention can reduce the recurrence rate ( WMD value was 0.20, 95% CI 0.13-0.31, P<0.01). Meta-analysis based on the intervention of establishing archives for continuous nursing showed that WMD value was 0.25, 95% CI 0.12-0.52, P<0.01, and archives and telephone showed that WMD value was 0.24, 95% CI 0.09-0.63, P=0.004, and the combined effect was statistically significant. Conclusions:Continuous nursing can improve the quality of life of patients with pancreatitis, improve the compliance with medical advice, and reduce the recurrence rate, but it needs to be further verified by a large sample, high-quality, multi-centered randomized controlled trial.

Objective:To investigate the cognitive impairment after intensive care unit (ICU) discharge and provide theoretical basis for prevention and intervention.Methods:Studies about cognitive impairment after ICU discharge were retrieved in PubMed, Embase, Cochrane Library, Web of Science, Wanfang data, CNKI and SinoMed from their foundation to December 2019. The literature screening and data extraction were performed by two researchers independently, and the quality of different types of researches was evaluated using Cochrane Handbook 5.1.0, Newcastle-Ottawa scale (NOS) and agency for healthcare research and quality criteria (AHRQ). The Meta-analysis was performed by Stata 13.0 software. Sensitivity analysis was used to determine the reliability of the combined effect values. Funnel plot and Egger test were used to analyze publication bias. The non-parametric clipping was used to evaluate the impact of publication bias on the results.Results:A total of 35 studies were enrolled, including 27 prospective cohort studies, 4 retrospective cohort studies, 2 randomized controlled trial (RCT) studies, 1 case-control study, and 1 cross-sectional study. Three literatures were published in Chinese and 32 were in English, which covered 13 countries, and a total of 102 504 ICU survivors were followed up successfully. Literature quality evaluation results showed that the NOS scores of 31 cohort studies were between 6 and 9, of which the case-control study scored 9. The quality grade of 2 RCT studies were both B. According to the AHRQ criteria, 1 cross-sectional study's design was scientifically rigorous and of high quality. Thirty-five studies reported that the overall incidence of cognitive impairment after ICU discharge ranged from 2.47% to 66.07%. For the multiple follow-ups studies, the first survey data was selected for Meta-analysis, and the results showed that the pooled incidence was 38.44% [95% confidence interval (95% CI) was 29.32-47.55]. Each study was removed for sensitivity analysis and the pooled results did not change much, which indicated that the results were reliable. The sub-group analysis was performed on different evaluation methods for cognitive impairment after ICU discharge, different types of ICU patients, and different follow-up time. The results showed that the pooled incidence of studies using neuropsychological test to evaluate cognitive impairment after ICU discharge was 31.42% (95% CI was 21.82-41.02), the pooled incidence of studies using questionnaires or scales was 38.75% (95% CI was 29.54-47.96), and the difference between the two groups was statistically significant ( P < 0.01). The pooled incidence of cognitive impairment after ICU discharge in general ICU patients was 43.42% (95% CI was 30.88-55.95), acute respiratory distress syndrome (ARDS) patients' pooled incidence was 34.40% (95% CI was 23.02-45.79), and the pooled incidence of elderly ICU patients was 12.93% (95% CI was 8.48-17.37), the difference among the three groups was statistically significant ( P < 0.01). The incidences of cognitive impairment < 1 year, 1 to 4 years, ≥ 5 years after ICU discharge were 43.30% (95% CI was 29.47-57.13), 34.21% (95% CI was 26.70-41.72), and 20.22% (95% CI was 4.89-35.55), respectively, and the differences among the three groups were statistically significant ( P < 0.01). The funnel plot showed that the distribution of all studies was asymmetric, and the Egger test result also suggested that there might be publication bias ( P < 0.05). The non-parametric clipping was used to estimate the impact of publication bias on the results, and the result showed that the difference in the incidence of cognitive impairment after ICU discharge before and after non-parametric clipping was large, suggesting that publication bias might influence the stability of the research results. Conclusions:The incidence of cognitive impairment after ICU discharge is relatively high and persistent for a long time, but diagnostic criteria of cognitive impairment and follow-up time are quite different. It is necessary to develop consistent evaluation criteria and rigorous designed research in the further.

Objective To observe the clinical effect of combining extracorporeal shock waves with pulsed radiofrequency irradiation of the dorsal root ganglia in the treatment of spinal cord-derived abdominal pain. Methods A total of 88 patients were randomly divided into a control group, a shock wave group, a pulsed irradiation group and a combination group, each of 22. All of the patients were given etocoxib and pregabalin medication for 3 weeks. In ad-dition to the drugs, the shock wave group received extracorporeal shock wave therapy, and the irradiation group re-ceived pulsed radio frequency irradiation of the dorsal root ganglia. The combination group received both. A visual an-alogue scale was used to assess perceived pain. The quality of life short form 36 ( QOL-SF36) , Hamilton anxiety scale and Hamilton depression scale were administered to all 4 groups before the treatments and after 1, 4 and 12 weeks of the treatments. The development of diseases, gastrointestinal function, medical treatment and medical expenses of the 4 groups were observed for two years after the treatments. Results After 4 weeks of treatment, the average scores of all four groups in all of the evaluations had improved significantly compared with before the treatment. In combination group′s average results were significantly better than those of the other 3 groups from 4 weeks until 12 weeks after the treatment. During the subsequent two years that group′s gastrointestinal symptoms, hospital visits and medical expen-ses were all significantly lower, on average, than those of the other groups. Conclusion Extracorporeal shock waves combined with pulsed radio frequency irradiation of the dorsal root ganglia has significant clinical efficacy for alleviating spinal cord-derived abdominal pain. It can significantly reduce medical costs and is worthy of clinical pro-motion.
