7High expression levels of IKK alpha and IKK beta are necessary for the malignant properties of liver cancer显示文摘IKK-NF-kappa B signaling is regarded as an important factor in hepatocarcinogenesis and a potential target for liver cancer therapy.Therefore,in this study,we analyzed the expression of mRNAs encoding components and targets of NF-kappa B signaling including IKK alpha,IKK beta,RANK,RANKL,OPG,CyclinD3,mammary serine protease inhibitor(Maspin),CyclinD1,c-FLIP,Bcl-x1,Stat3,Cip1 and Cip2 by real-time PCR in 40 patients with liver cancer.After statistical analysis,7 indices including IKK alpha,IKK beta,RANK,Maspin,c-FLIP,Cip2 and cyclinD1 were found to show significant differences between tumor tissue and its corresponding adjacent tissue.When IKK alpha and IKK beta were downregulated in the hepatocellular carcinoma(HCC) cell lines of MHCC-97L and MHCC-97H in vitro,the numbers of BrdU positive cells were decreased in both IKK alpha and IKK beta knockdown cells.Levels of apoptosis were also investigated in IKK alpha and IKK beta knockdown cells.The growth of HCC was inhibited in the subcutaneous implantation model,and lung metastatogenesis was also significantly inhibited in the kidney capsule transplantation model.Downregulation of IKK alpha and IKK beta in HCC cultured in vitro revealed that increased Maspin,OPG and RANKL expression was associated with metastasis of HCC.These findings were associated with downregulation of Bcl-XL and c-FLIP,which may be the reason for increased apoptosis.The therapeutic effect of IKK alpha and IKK beta downregulation depends on extent of NF-kappa B inhibition and the malignant nature of the HCC.We anticipate that IKK-targeted gene therapy can be used in the treatment of HCC,a cancer that is notoriously resistant to radiation and chemotherapy.Jiang,RQ Xia,YX Li,J Deng,L Zhao,L Shi,J Wang,XH Sun,BC Nanjing Med Univ,Liver Transplantat Ctr,Affiliated Hosp 1,Nanjing,Jiangsu Prov,Peoples R China Nanjing Med Univ,Ctr Canc,Nanjing,Jiangsu Prov,Peoples R China 2010南京医科大学学报(自然科学版)2010,30,5:13
8膳食中钠(盐)与血压的关系及其他膳食因素可能的调节作用显示文摘现有资料表明,膳食钠(盐)与血压直接相关。以往大多数研究结果来自缺乏膳食数据的研究;因此,这种钠-血压关系是否受其他膳食因素调节尚不清楚。国际宏量/微量营养素和血压研究(international study on macro/micronutrients and blood pressure,INTERMAP)结果显示,在控制多种非膳食因素情况下,年龄40~59岁的男性和女性4680人(中国、日本、英国和美国的17个人口样本)的血压与24h尿钠排泄和尿钠/钾直接相关。刘莉 叶鹏 Stamler J Chan Q Daviglus ML Dyer AR Van Horn L Garside DB Miura K Wu Y Ueshima H Zhao L Elliott P INTERMAP Research Group 2018中华高血压杂志2018,26,4:8
9桑叶多糖对早期断奶仔猪生长性能、腹泻、血液指标和肠道菌群的影响显示文摘研究旨在探讨日粮补充桑叶多糖(MLPs)对早期断奶仔猪生长性能、腹泻、血液生化指标和肠道菌群的影响。共选取(28±2)日龄、体重为(9.18±0.46)kg的'杜洛克×长白×约克夏'杂交断奶仔猪150头,随机分成5个处理组,每组6个重复,每个重复5头猪。饮食处理如下:对照组(CT):基础日粮(BD);低剂量桑叶多糖组(LT):0.3 g·kg-1MLPs+BD;中剂量桑叶多糖组(MT):0.6 g·kg-1MLPs+BD;高剂量桑叶多糖组(HT):0.9 g·kg-1MLPs+BD;抗生素处理组(AT):0.15 g·kg-1金霉素+BD。分别在第0、10、21天的早晨,每头猪空腹测量体重并记录采食量,这些数据用来计算平均日增重(ADG)、平均日采食量(ADFI)和料重比(F/G)。每天两次(上午和下午)对每头仔猪的腹泻状况进行检查并记录。在试验结束时,收集血液样本用于生化分析,并收集盲肠、结肠和直肠内容物进行识别和量化相关的肠道菌群。研究结果表明,MLPs处理组间的日增重、平均日采食量和料重比无显著差异(P>0.05),但低剂量组(LT)、中剂量组(MT)、高剂量组(HT)的平均日采食量高于对照组(CT)和抗生素组(AT)。并且,LT、MT和HT组的料重比低于CT和AT组。与CT和AT组相比,LT、MT和HT组仔猪的腹泻发病率也显著降低(P<0.05)。生化分析表明,MLPs各处理组仔猪的血糖(GLU)水平均显著低于CT或AT组(P<0.05)。MT和HT组血液尿素氮(BUN)水平与CT和AT组存在显著差异(P<0.05),HT组T3水平显著高于CT和AT组(P<0.05)。虽然MLPs各处理组的T4水平与AT组并没有显著差异(P>0.05),但MT组的胰岛素样生长因子Ⅰ(IGF-Ⅰ)和生长激素(GH)水平较CT或AT组均显著升高(P<0.05)。LT、MT和HT 3组在抑制肠道大肠杆菌生长和促进肠道乳酸杆菌和双歧杆菌生长的整体效果上均优于CT和AT组。值得注意的是,与CT和AT组相比,HT组(0.9 g·kg-1MLPs)对抑制肠道大肠杆菌以及促进肠道有益菌群具有更显著效果(P<0.05)。结果表明,日粮添加桑叶多糖可以改善早期断奶仔猪肠道菌群的生态环境,降低腹泻率,提高整体生长性能。Zhao X J Lin L Luo Q L Ye M Q Luo G Q Kuang Z S 2015饲料博览2015,0,7:7

11茶叶摄入与中国成年人高密度脂蛋白胆固醇浓度纵向变化的关系显示文摘茶叶摄入与高密度脂蛋白胆固醇(high-density lipoprotein cholesterol,HDL-C)浓度的年龄相关变化之间的关系仍不清楚。该研究目的是探索茶摄入量与HDL-C浓度纵向变化之间的关系。研究人员通过调查问卷评估基线(2006年)的茶叶消费量,并在2006、2008、2010和2012年测量了未患有心血管病或癌症.刘莉 叶鹏 Huang S Li J Wu Y Ranjbar S Xing A Zhao H Wang Y Shearer GC Bao L Lichtenstein AH Wu S Gao X 2018中华高血压杂志2018,26,8:5
12First-Principles Study of Phase Stability and Mechanical Property of Co_3(Al,W) Precipitates with Different Ratio of Al to W in Co Base Alloys显示文摘The energetics, electronic structure and mechanical property of Co3(Al,W) precipitates with different ratio of Al to W in Co base alloys were investigated by the method of supercell and augmented plane waves plus local orbitals within generalized gradient approximation. The calculated results show that the L12 Co3(Al,W) precipitate is the most stable when the ratio of Al to W is equal to 1. When the content of W is higher than 18.5 at%, the L12 and hexagonal structures co-exist in Co3(Al,W) precipitates at 1173 K. It is also shown that the L12 ordered Co3(Al,W) precipitates have an obvious strengthening effect in the disordered fcc cobalt matrix.Yao Q Su X M Yan Y Zhao L W Sun J 2009稀有金属材料与工程2009,38,A03:3
