Objective To investigate the molecular regulatory mechanism of glucagon like peptide 1 (GLP-1) on proliferation, differentiation and apoptosis of human umbilical cord blood endothelial progenitor cells (EPCs). Methods EPCs were isolated from the umbilical cord blood of healthy pregnant women and cultured in 6-hole cell plate at 2×105 density in vitro, transfected with empty vector plasmid (control group), pcDNA3-GLP-1 plasmid (GLP-1 group), pcDNA3-GLP-1plasmid+AMD3100 (GLP-1+AMD3100 group) and simple AMD3100 (AMD3100 group). The pcDNA3-GLP-1 was transfected into EPCs. The 25μmol/L AMD3100 was used to block the SDF-1/CXCR4 signal pathway of EPCs for 1 h. The cell proliferation was determined by MTT method. The mRNA expressions of differentiation and apoptosis related genes PPARγ, C/EBPα and Caspase-3 were investigated by RT-PCR, and Caspase-3 activity was determined by Caspase-3 activity assay kit. Results Compared to control group, AMD3100 inhibitor showed no effects on cell proliferation, differentiation and apoptosis, while over-expression of GLP-1 in EPCs obviously promoted cell proliferation, and differentiation related genes PPARγand C/EBPαmRNA expression, but down-regulated mRNA expression and the activity of Caspase-3 significantly (P＜0.05), indicating that GLP-1 increased proliferation and differentiation of EPCs while decreased cell apoptosis. When the SDF-1/CXCR4 signaling pathway was blocked by AMD3100, over-expression of GLP-1 induced promotion of cell proliferation, and the differentiation was decreased significantly and the apoptosis was significantly increased (P＜0.05). Conclusion These data confirm that GLP-1 might promote EPCs proliferation and differentiation, and inhibit cell apoptosis through the regulation of the SDF-1/CXCR4 signaling pathway.

Objective:To investigate the characteristics of the sleep quality and health-related quality of life (HRQoL), and analyze the different effects of sleep quality on HRQoL among young and middle-aged people.Methods:A cross-sectional study recruited 1 976 participants.All participants completed a self-designed questionnaire for the adults' general condition, the Pittsburgh sleep quality index (PSQI) and Short-Form health survey (SF-36). All participants were divided into 3 age groups: 18-29-year-old group( n=1 148), 30-44-year-old group( n=586) and 45-59-year-old group ( n=242). SPSS 23.0 software was used for statistical analysis.Chi-square test was used to analyze the general characteristics of the three age groups.Non-parametric test was used to analyze the scores of the three age groups in different dimensions of sleep quality. One-way ANOVA was used to analyze the mean scores of the three age groups in different dimensions of HRQoL. Stepwise regression analysis was used to analyze the effect of sleep quality on HRQoL among the three groups after control the confounding factors such as marital status, education, smoking, drinking and exercise habits and past medical history. Results:In terms of sleep quality, the total PSQI scores of 18-29-year-old, 30-44-year-old and 45-59-year-old groups(4(2, 6), 4(2, 6), 4(2, 6)) showed statistically significant differences ( Z=10.951, P=0.004). In terms of HRQoL, there were statistically significant differences in physical component summary scores (18-29-year-old: 82.51±12.62, 30-44-year-old: 80.72±13.63, 45-59-year-old: 82.04±13.07, F=3.667, P=0.026) and mental component summary scores(18-29-year-old: 76.09±15.46, 30-44-year-old: 77.20±16.14, 45-59-year-old: 81.82±14.14, F=13.649, P<0.001) among young and middle-aged people in different age groups.Regression analysis found that daytime dysfunction was an independent influencing factor for HRQoL in young and middle-aged population ( β=-0.308--0.425, all P<0.01). Sleep disorders significantly decreased Physical Component Summary of HRQoL in young-aged people ( β=-0.127--0.215, all P<0.01). The use of hypnotic drugs significantly reduced the scores in the physiological field in the young adults aged 30-44 ( β=-0.076, P<0.05). The duration of sleep significantly decreased the scores in the mental domain of young adults aged 30-44 ( β=-0.112, P<0.01). Subjective sleep quality was an independent factor that significantly decreased HRQoL in young adults aged 18-29 and 30-44 years ( β=-0.089--0.169, all P<0.01). Conclusion:Sleep quality and HRQoL of young and middle-aged people in different age groups show different characteristics.The effect of sleep quality on HRQoL is different among people in different ages.Taking targeted interventions for people of different ages to improve the sleep quality may be an effective way to improve their HRQoL.

Objective To investigate the relationship between histological chorioamnionitis(HCA) and the outcome of preterm labor. Methods A total of 218 cases of premature delivery in the Department of Obstetrics and Gynecology of our hospital from January, 2015 to December, 2017 were divided into two groups according to the result of placenta pathological diagnosis. The observation group was diagnosed with histological chorioamnionitis by placenta pathology examination. The control group was not diagnosed with histological chorioamnionitis. The delivery gestational week, the rate of premature rupture of membranes, the rate of puerperal infection, the rate of postpartum hemorrhage, the rate of wound healing failure, the average body mass of newborn infants, the rate of early-onset sepsis, asphyxia, respiratory distress syndrome rate, pathological jaundice rate, neonatal mortality between the two groups were compared. And the impact of histological chorioamnionitis on the outcome of preterm labor was explored. Results The delivery gestational week of the observation group was (32. 0±1. 0) weeks, and the rate of postpartum hemorrhage, the rate of premature rupture of membranes, the rate of puerperal infection and the rate of wound healing were 21. 24％, 80. 50％, 16. 81％, 11. 50％, respectively. The delivery gestational week of the control group was(34. 0±1. 0) weeks, and the rate of postpartum hemorrhage, the rate of premature rupture of membranes, the rate of puerperal infection and the rate of wound healing were 10. 48％, 65. 70％, 7. 62％, 3. 81％, respectively. The delivery gestational week of the observation group was small. And the rate of premature rupture of membranes, wound healing failure rate, puerperal infection rate, postpartum hemorrhage rate in the observation group was significantly higher than that of the control group, and the difference was statistically significant(P＜0. 05). The mean neonatal weight in the observation group was(1710±355)g,and the asphyxia rate, early-onset sepsis rate, respiratory distress syndrome rate, pathological jaundice rate and neonatal mortality were 21. 24％, 33. 63％, 38. 05％, 19. 47％ and 9. 73％. The mean neonatal weight in the control group was(2270±450)g,and the asphyxia rate, early-onset sepsis rate, respiratory distress syndrome rate, pathological jaundice rate, neonatal mortality were 9. 52％, 18. 10％, 12. 38％, 8. 57％, 2. 86％. The average body weight of infants in the observation group was low. And the rates of early onset sepsis, asphyxia, respiratory distress syndrome, pathological jaundice and neonatal mortality were significantly increased. The difference was significant (P＜0. 05). Conclusion The placental pathology examination in all preterm patients should be done to avoid missed diagnosis of HCA, and to help early diagnosis and treatment of pregnant women with intrauterine infection and high-risk newborns and improve prognosis.

Objective:To explore the application effects of work record analysis combined with emergency plan drill on the practice teaching of nursing students in department of emergency.Methods:A total of 80 nursing students who had clinical practice in the Department of Emergency of Beijing Shijitan Hospital Affiliated to Capital Medical University between February 2018 and August 2020 were selected as research subjects. They were divided into control group and observation group according to the admission order to the department. The control group was given routine teaching, and the observation group adopted work record analysis combined with emergency plan drill teaching. The theoretical knowledge level, the success rate of emergency treatment and teaching effect evaluation were compared between the two groups of nursing students before and after learning. SPSS 19.0 was used for t test and chi-square test. Results:After learning, the scores of theoretical knowledge (pre-hospital emergency, common emergency diseases, emergency treatment plan, and complications) of the two groups were higher than those before learning, and the scores in observation group were higher than those in control group ( P<0.05). The success rates of emergency treatments (electrocardiogram, electrocardiogram monitoring, blood sample collection, thrombolytic therapy coordination, and cardiopulmonary resuscitation) and satisfaction rates of teaching effects (fully understanding emergency work, improving the ability of independent learning, enhancing the ability of flexible use of knowledge, and active classroom atmosphere) were higher in observation group than control group ( P<0.05).

On-site supervision is a risk-based regulatory system that requires the scientific development of supervision plans for quality risks and hidden dangers in pharmaceutical enterprises， the rational allocation of supervision resources based on their risk levels， and the implementation of classified supervision measures. In this study， the quality risk monitoring business support system is set up for pharmaceutical enterprises by establishing the quality risk expert database and quality risk monitoring index system for pharmaceutical enterprises based on the difficulty analysis of on-site drug supervision. Based on this support system， the quality risk classification method， the differentiated spot check strategy and business auxiliary visualization system are established. This support system is used to learn the risk level of pharmaceutical enterprises， so as to innovate supervision methods and optimize monitoring strategies. Taking Jiangxi Province as an example， it is verified that the support system can guide the risk assessment of sample enterprises， can improve the targeting of on-site drug supervision in the process of technical review， scheme editing， on-site implementation and comprehensive evaluation， and can effectively improve the quality and efficiency of supervision.

Objective: In this study, we tested for the presence of four human coronaviruses (HCoVs) in children with respiratory tract disease in Fuzhou, Fujian, China. Methods: Nasopharyngeal aspirates were collected from children with respiratory tract disease from Nov, 2007 to Jan, 2015. A total of 266 clinical samples were tested for HCoVs using reverse-transcription polymerase chain reaction (RT-PCR). The positive products were sequenced and compared with those in GenBank by BLAST. The positive samples were then tested for HCoV-HKU1 and HCoV-NL63 using RT-PCR method . We compared the 440 bp pol gene sequence of the 8 HCoV isolates in Fuzhou, China to other HCoV isolates documented in the GenBank database by using MEGA software version 6.06 and the neighbor-joining method . Results: HCoVs were detected in 8 patients (3.0%) out of the 266 children. Two of 266 (0.38%) were positive for HCoV-HKU1; 1 of 266(0.38%)were positive for HCoV-NL63; 1 of 266 (0.38%) were positive for HCoV-229E; 4 of 266 (1.5%)were positive for HCoV-OC43. All of children who were positive for HCoV had respiratory illness. Two HCoV-HKU1 were found to co-infect with human parainfluenza virus type 3 (HPIV-3). The 8 HCoV strains in our study fell into four clusters. Two strains of HCoV-HKU1 were genotype A. Conclusions HCoV infections were probably associated with upper and lower respiratory illness in children. Additional studies are needed to investigate the potential roles of these HCoVs in diseases.

The clustered regularly interspaced short palindromic repeats (CRISPR)-Cas9 system has been widely used for genome engineering and transcriptional regulation in many different organisms. Current CRISPR-activation (CRISPRa) platforms often require multiple components because of inefficient transcriptional activation. Here, we fused different phase-separation proteins to dCas9-VPR (dCas9-VP64-P65-RTA) and observed robust increases in transcriptional activation efficiency. Notably, human NUP98 (nucleoporin 98) and FUS (fused in sarcoma) IDR domains were best at enhancing dCas9-VPR activity, with dCas9-VPR-FUS IDR (VPRF) outperforming the other CRISPRa systems tested in this study in both activation efficiency and system simplicity. dCas9-VPRF overcomes the target strand bias and widens gRNA designing windows without affecting the off-target effect of dCas9-VPR. These findings demonstrate the feasibility of using phase-separation proteins to assist in the regulation of gene expression and support the broad appeal of the dCas9-VPRF system in basic and clinical applications.
