CPI在宏观经济决策中发挥举足轻重的作用,但其准确性一直受到人们的质疑。大数据时代的到来,尤其是扫描数据的出现为CPI样本量不足、指数计算公式选择空间有限等问题的解决提供了数据基础。UNECE部分成员国利用这一契机,与超级连锁店等扫描数据供应商签署数据供应协议,有效地推进了扫描数据在CPI编制中的实践应用。在此基础上,我国相关统计部门应积极研究、借鉴国际经验,拓宽CPI原始数据来源渠道和指数计算公式选择余地,尝试编制扫描物价指数,为提高CPI数据发布的及时性、准确性作出努力。 展开更多

A 71-year-old man was admitted with epigastric pain. Initial endoscopic findings revealed multiple, active gastric ulcers in the gastric antrum. He underwent Helicobacterpylori (Hpylon) eradication therapy followed by proton pump inhibitor (PPI) therapy. However, follow- up endoscopy at 4, 6, 10 and 14 mo revealed persistent multiple gastric ulcers without significant improvement. The proportion of his eosinophil count increased to 43% (total count: 7903/mm3). Abdominal-pelvic and chest computed tomography scans showed multiple small nodules in the liver and both lungs. The endoscopic biopsy specimen taken from the gastric antrum revealed prominent eosinophilic infiltration, and the liver biopsy specimen also showed eosinophilic infiltration in the portal tract and sinusoid. A bone marrow biopsy disclosed eosinophilic hyperplasia as well as increased cellularity of 70%. The patient was finally diagnosed with HES involving the stomach, liver, lung, and bone marrow. When gastric ulcers do not improve despite H pylon eradication and prolonged PPI therapy, infiltrative gastric disorders such as HES should be considered. 展开更多
