2电商发展对CPI的影响研究——基于大数据背景下线上线下价格波动的同步性分析显示文摘该文利用阿里巴巴研究院公布的ASPI指数以及国家统计局公布的CPI历史数据作为反映线上和线下商品价格变动的指示变量并采用动态相关模型分析了两种价格指数之间的波动溢出效应。研究表明,线上、线下商品价格水平变动虽然存在相互显著的波动溢出效应,但是线上商品对于线下商品价格的影响要更大一些,说明现阶段CPI统计制度没有将线上商品价格纳入CPI篮子的非科学性。两类指数动态相关系数的实证分析表明电子商务的快速发展虽然整体推动了线上消费在居民消费中的比重,但是受到CPI统计制度的影响以及商品自身消费属性以及物理、化学属性的差异使得线上商品价格与线下商品价格之间的联系越来越小,两类指数呈现独立化发展趋势并直接影响了CPI的真实性与准确性。田涛 2016上海经济研究2016,28,3:10
3Small-bowel mucosal injuries in low-dose aspirin users with obscure gastrointestinal bleeding显示文摘AIM: To investigate the clinical differences between small intestinal injuries in low-dose aspirin(LDA) users and in non-steroidal anti-inflammatory drug(NSAID) users who were examined by capsule endoscopy(CE) for obscure gastrointestinal bleeding(OGIB). METHODS: A total of 181 patients who underwent CE for OGIB were included in this study. Based on clinical records, laboratory data such as hemoglobin levels, major symptoms, underlying diseases, the types and duration of LDA and NSAID use, and endoscopic characteristics of CE were reviewed.RESULTS: Out of a total of 45 cases of erosive lesions, 27 cases were taking LDA or NSAIDs(7 were on NSAIDs, 9 were on LDA alone, 9 were on LDA and thienopyridine, and 2 were on LDA and warfarin).The prevalence of ulcers or erosion during chronic use of LDA, LDA and the anti-platelet drug thienopyridine (clopidogrel or ticlopidine), and NSAIDs were 64.3%, 80.0%, and 75.0%, respectively. Erosive lesions were observed predominantly in chronic LDA users, while ulcerative lesions were detected mainly in NSAID users. However, concomitant use of thienopyridine such as clopidogrel with LDA increased the proportion of ulcers. The erosive lesions were located in the whole of the small intestine(jejunum and ileum), whereas ulcerative lesions were mainly observed in the ileum(P < 0.05). CONCLUSION: Our CE findings indicate that chronic LDA users and NSAID users show different types and locations of small-bowel mucosal injuries. The concomitant use of anti-platelet drugs with LDA tends to exacerbate the injuries from LDA-type to NSAID-type injuries.Junichi Iwamoto Yuji Mizokami Yoshifumi Saito Koichi Shimokobe Akira Honda Tadashi Ikegami Yasushi Matsuzaki 2014World Journal of Gastroenterology2014,20,36:9
4Interaction between Helicobacter pylori infection, nonsteroidal anti-inflammatory drugs and/or low-dose aspirin use: Old question new insights显示文摘Previous reports clearly demonstrated that Helicobacter pylori(H.pylori)infection,nonsteroidal anti-inflammatory drugs(NSAID)or low dose aspirin(ASA)use significantly and independently increased the risk for the development of peptic ulcer disease.Today,the presence of H.pylori infection associated with low dose ASA and/or NSAID use in the same patient is becoming more frequent and therefore the potential interaction between these factors and the consequences of it has important implications.Whether NSAID intake in the presence of H.pylori infection may further increase the risk of peptic ulcer carried by the presence of only one risk factor is still a matter of debate.Studies on the interaction between the two risk factors yielded conflicting data and no consensus has been reached in the last years.In addition,the interaction between H.pylori infection and low-dose ASA remains even more controversial.In real clinical practice,we can find different clinical scenarios involving these three factors associated with the presence of different gastrointestinal and cardiovascular risk factors.These huge variety of possible combinations greatly hinder the decision making process of physicians.Carlos Sostres Carla Jerusalen Gargallo Angel Lanas 2014World Journal of Gastroenterology2014,20,28:8
5大数据背景下电商发展对CPI的影响——基于线上线下价格波动同步性分析显示文摘本文利用阿里研究院所公布的反映网络商品价格波动的ASPI物价指数,以及国家统计局公布的CPI历史数据,依据共同趋势与共同周期理论来分析不同分类的线上商品对CPI的影响。研究表明:ASPI分类消费者价格指数与CPI之间表现出显著协同性,说明线上分类消费者价格指数与线下消费者价格指数不仅在长期具有相似的随机趋势,而且其短期波动也是相互同步影响的,其中家庭设备用品及维修服务以及衣着对于线下一般商品和服务的价格影响最大,而医疗保健以及烟酒及用品对CPI的影响最小。周薇薇 田涛 2016商业研究2016,,4:5

8Arabidopsis small ubiquitin-related modifier protease ASP1 positively regulates abscisic acid signaling during early seedling development~~显示文摘The small ubiquitin-related modifier(SUMO)modification plays an important role in the regulation of abscisic acid(ABA)signaling,but the function of the SUMO protease,in ABA signaling,remains largely unknown.Here,we show that the SUMO protease,ASP1 positively regulates ABA signaling.Mutations in ASP1 resulted in an ABA-insensitive phenotype,during early seedling development.Wild-type ASP1 successfully rescued,whereas an ASP1 mutant(C577S),defective in SUMO protease activity,failed to rescue,the ABA-insensitive phenotype of asp1-1.Expression of ABI5 and MYB30 target genes was attenuated in asp1-1 and our genetic analyses revealed that ASP1 may function upstream of ABI5 and MYB30.Interestingly,ASP1 accumulated upon ABA treatment,and ABA-induced accumulation of ABI5(a positive regulator of ABA signaling)was abolished,whereas ABA-induced accumulation of MYB30(a negative regulator of ABA signaling)was increased in asp1-1.These findings support the hypothesis that increased levels of ASP1,upon ABA treatment,tilt the balance between ABI5 and MYB30towards ABI5-mediated ABA signaling.Qiongli wang Gao-Ping Qu Xiangxiong Kong Yan Yan Jigang Li Jing Bo Jin 2018Journal of Integrative Plant Biology2018,60,10:4

10居民网络消费价格指数编制:实践经验、问题与展望显示文摘随着居民网络消费的急剧增长,编制居民网络消费价格指数的必要性凸显;但网络消费大数据具有更新快、容量大、频率高、噪音多等特点,传统价格指数理论和方法难以适用。aSPI和1号店指数的编制实践,从源头上优化了基础数据质量,提高了商品篮子的代表性和时效性,指数构造方法更为科学,并开发了系列创新型价格指数,但也存在信息登记标准和规范不统一、大数据技术运用和数据处理不充分、方法和数据发布不完整、理论和方法创新不足等问题。因此,还需要大力促进网络消费数据的共享,系统推动网络消费价格指数理论和方法的创新,积极推进相关统计规范和标准的制定与应用,并进一步强化创新型特色价格指数编制的实践探索。陈立双 2019西部论坛2019,29,2:3
