Flow-induced Expression and Phosphorylation of VASPin Endothelial Cells

1 Introduction It is well known that mechanical forces have important influence on endothelial cells, in particular, on cytoskeleton reorganization. VASP (vasodilator stimulated phosphoprotein) is a 46 KD actin associated protein. It is a member of Ena/VASP protein family and composed of EVH1, proline-rich and EVH2 domains. It is considered as an important component of the sub-cellular regions where remodelling of the actin cytoskeleton takes place, such as the front of spreading lamell…     

重组结核分枝杆菌特异性分泌抗原融合蛋白的活性鉴定及初步应用

目的：融合表达结核分枝杆菌分泌蛋白CFP10-ESAT-6或ESAT-6-CFP10，研究其免疫学特性，为结核病的血清学诊断提供物质基础。方法：将一个柔性的氨基酸“接头”插入原核表达载体pET32c（＋）中，构建pET32c（＋）-linker。PCR法扩增CFP10、ESAT-6基因。将CFP10克隆入改建的载体pET32e（＋）的linker前，ESAT-6克隆入linker后，构建CFP10-ESAT-6融合基因；或将ESAT-6克隆入改建的载体pET32c（＋）的linker前，CFP10克隆入linker后，构建ESAT-6-CFP10融合基因，分别转化大肠杆菌XL1-blue，抽提质粒，酶切鉴定；在大肠杆菌B121中表达，通过Western blot分析其抗原性。结果：两个目的基因分别被按顺序成功克隆入载体pET32c（＋）的linker前或后。重组质粒pET32c（＋）-CFP10-ESAT-6或pET32c（＋）-ESAT-6-CFP10靶基因的测序结果与预计序列完全一致。融合蛋白在B121菌中高效表达。Western blot分析表明，融合蛋白与活动性肺结核患者血清能发生特异性免疫反应。结论：成功地构建了多抗原基因DNA质粒；pET32e（＋）-CFP10-ESAT-6或pET32c（＋）-ESAT-6-CFP10质粒在B121菌中能高效表达rCFP10-ESAT-6或rESAT-6-CFP10融合蛋白，该蛋白兼具CFP10和ESAT-6两种蛋白的抗原性。本研究为rCFP10-ESAT-6或rESAT-6-CFP10融合蛋白在结核病血清学诊断中应用奠定了基础。     

Chronic neuroprotective effects of low concentration lithium on SH-SY5Y cells:possible involvement of stress proteins and gene expression

To investigate the molecular mechanism underlying the neuroprotective effect of lithium on cells, in this study, we exposed SH-SY5Y cells to 0.5 mmol/L lithium carbonate(Li2CO2) for 25–50 weeks and then detected the expression levels of some neurobiology related genes and post-translational modifications of stress proteins in SH-SY5Y cells. cDNA arrays showed that pyruvate kinase 2(PKM2) and calmodulin 3(CaM 3) expression levels were significantly down-regulated, phosphatase protein PP2A expression was lightly down-regulated, and casein kinase II(CK2), threonine/tyrosine phosphatase 7(PYST2), and dopamine beta-hydroxylase(DBH) expression levels were significantly up-regulated. Besides, western blot analysis of stress proteins(HSP27, HSP70, GRP78 and GRP94) showed an over-expression of two proteins: a 105 kDa protein which is a hyper-phosphorylated isoform of GRP94, and a 108 kDa protein which is a phosphorylated tetramer of HSP27. These results suggest that the neuroprotective effects of lithium are likely related to gene expressions and post-translational modifications of proteins cited above.

心血管病高危与非高危人群的生存质量比较:倾向评分匹配分析

目的探究心血管病高危与非高危人群生存质量差异。方法采用2015-2017年国家心血管病高危人群早期筛查与综合干预项目江苏省项目点调查数据,对调查对象进行问卷调查和体格检查,运用倾向评分匹配分析(PSM)方法,按照1∶1匹配心血管病高危组与非高危组间性别和年龄,采用多重线性回归模型分析心血管病高危对生存质量[欧洲五维度健康量表(EQ-5D)]得分及其中的直观相似尺度(EQ-VAS)评分的影响。结果调查对象40 243(高危组20 839,非高危组19 404)人,倾向评分匹配后得到调查对象31 605(高危组15 948,非高危组15 657)人,EQ-5D指数得分0.97±0.07,EQ-VAS评分79.83±9.36,高危组行动能力、自理能力、日常生活能力和疼痛/不适报告有困难率高于非高危组(1.9%比1.0%、0.6%比0.3%、1.5%比0.8%、16.8%比15.7%,均P<0.05);高危组与非高危组焦虑/不适报告有困难率差异无统计学意义(4.5%比4.4%,P=0.785);女性、高龄、不在婚、初中及以下学历、不吸烟、不饮酒、肥胖、患有高血压、患有血脂异常的调查对象EQ-5D指数得分和EQ-VAS评分低于不在此状态或不患有此疾病人群(P<0.05),家庭年收入≤5万元、患有糖尿病的调查对象EQ-VAS评分低于不在此状态或不患有此疾病人群(P<0.001);多因素线性回归分析显示,调整基本情况和主要慢性病情况后,高危组EQ-VAS评分降低(β=-0.054, 95 CI-1.264^-0.766,P<0.001)。结论高危组人群的EQ-VAS评分低,应关注心血管病高危人群的生存质量。     

徐州市农村地区65岁及以上老年人健康管理服务开展情况调查

目的了解徐州市农村地区65岁及以上老年人健康管理服务开展情况。方法采用多阶段抽样方法,抽取徐州市农村地区400名65岁及以上老年人,采用自行设计的调查表对居民一般情况、建档情况、免费体检情况及健康指导情况进行调查。结果被调查人群中建立健康档案、接受免费体检以及得到健康指导的比例分别为74.6%、70.2%和45.3%,不同考核排名间的乡镇在老年人建档、免费体检以及健康指导提供间的差异均有统计学意义(P<0.05)。不同年龄组间在健康体检以及健康指导间的差异有统计学意义(P<0.05)。而不同性别、职业和文化程度之间在建档情况、健康体检以及健康指导提供上差异均无统计学意义(P>0.05)。结论徐州市农村地区针对65岁及以上老年人的健康管理工作取得了一定的成绩,但该项工作开展的很不均衡,应通过政策宣传、健康教育、增加培训和督导等措施,不断提高针对老年人的健康管理服务水平。     

Interleukin 28B-related polymorphisms: A pathway for understanding hepatitis C virus infection?

AIM:To analyze the role of rs12979860 and rs8099917polymorphisms in hepatitis C virus(HCV)genotype 1infection of Brazilians.METHODS:A total of 145 adult patients diagnosed with genotype 1 chronic hepatitis C(CHC)who had completed a 48-wk regimen of pegylated-interferonα-2a or-2b plus ribavirin combination therapy were recruited from six large urban healthcare centers and199 healthy blood donors(controls)from a single site between January 2010 and January 2012.Data on the patients’response to treatment was collected.Polymerase chain reaction-restriction fragment length polymorphism genotyping of the interleukin(IL)28B gene fragment encompassing the single nucleotide polymorphisms(SNPs)rs12979860(C/T)and rs8099917(T/G)was carried out for 79 of the CHC patients and 199 of the controls.Bi-directional amplicon sequencing of the two SNPs was carried out for the remaining 66 CHC patients.RESULTS:SNP rs12979860 genotyping was successful in 99.5%of the controls and 97.2%of the CHC patients,whereas the SNP rs8099917 genotyping was successful in 95.5%of the controls and 100%of the CHC patients.The genotype and allele distributions for both rs12979860 and rs8099917 were significantly different between the control and CHC patient groups,with significantly higher genotype frequencies of CC and TT in the controls(P=0.037 and 0.046,respectively)and of TT and GG in the CHC patients(P=0.0009and 0.0001,respectively).Analysis of the CHC patients who achieved sustained virological response(SVR)to treatment(n=55)indicated that the rs12979860 C allele and CC genotype were predictors of SVR(P=0.02).No significant correlation was found between rs8099917 genotypes and treatment response,but carriers of the T allele showed significantly higher rates of SVR(P=0.02).Linkage disequilibrium analysis of the group that achieved SVR showed a significant association between rs12979860 and rs8099917(P=0.07).CONCLUSION:The higher allele frequency of rs12979860 C and rs8099917 T observed in non-HCVinfected individuals may indicate a potential pro
