Objective: The burden of gastric cancer(GC) across different age groups needs updating. We determined the GC global, regional, and national burden profiles and changes in incidence for 3 sequential 5-year intervals from 2003 to ***: The latest incidence and mortality estimates of GC from 185 countries and regions were extracted from the GLOBOCAN 2022 database. The 5-year interval age-standardised incidence rates(ASIRs) were evaluated using cancer registry data from volumes X±XII of the Cancer Incidence in Five Continents(CI5). Correlation analysis was used to evaluate the relationship between ASIR or the age-standardised mortality rate(ASMR) and the Human Development Index(HDI).Results: There was an estimated global 968,000 new GC cases and 660,000 deaths in 2022, with male predominance. GC ASIRs and ASMRs were 9.2 and 6.1 per 100,000 persons, respectively. East Asia had the highest burden, with 53.8% of cases and 48.2% of deaths among all geographic regions. There was a significant correlation between ASIR and HDI. Over three 5-year intervals from 2003 to 2017, the incidence of GC notably decreased in most countries but peaked at 2008±2012 in New Zealand, Turkey, and South Africa. Several countries in Europe, Oceania, and America suggest an increasingly concerning trend among younger individuals, especially ***: GC is a significant health issue, especially among males and in geographic regions with an HDI, such as eastern Asia. While the incidence of GC is decreasing in many countries due to prevention efforts and improved treatments, a rising trend persists among younger individuals. Comprehensive prevention strategies tailored to different age patterns are clearly needed.

目的对温州地区未治疗艾滋病(AIDS)病人体内艾滋病病毒(HIV)毒株耐药基因的突变情况进行调查分析,了解该地区AIDS病人的本底耐药情况。方法对50例未接受抗病毒治疗的AIDS病人HIVpol区的蛋白酶(PR)全长和部分反转录酶(RT)基因进行扩增、脱氧核糖核酸(DNA)测序、亚型鉴定,并与国际HIV耐药数据库比对分析。结果共获得38份有效序列,根据pol区亚型分析发现,CRF01_AE占36.8%(14例),CRF07_BC重组占36.8%(14例),C亚型占18.4%(7例),B亚型占7.89%(3例)。未检出针对蛋白酶抑制剂(PIs)、核苷类反转录酶抑制剂(NRTIs)的耐药病例。针对非核苷类反转录酶抑制剂(NNRTIs)检出3例耐药病例,突变类型分别为V179D、E138A和K103N。同时,2015年温州HIV耐药毒株的传播水平<5%,处于低传播水平。结论对于未经抗病毒治疗组,耐药基因型以CRF01_AE重组、BC重组为主,HIV耐药毒株在温州仍处于低度传播水平,发现一个重要耐药基因突变位点是K103N。

In power supply industry, problems of semantic conflict incurred from heterogeneous data resources become more and more serious, so as to be regarded as the difficulty of data integration. Based on semantic heterogeneity in the data integration, in this paper, ontology was introduced into electric power system, and a computing approach on comprehensive concept similarity was proposed to realize ontology mapping. In other words, calculate concept similarity based on the concept name, concept attributes, concept relations and concept instances, then merge similarity by giving weights, so the calculation of the concept similarity is more comprehensive and more accurate. The unambiguous share and reuse of power information are realized on semantic level.

Tropical cyclones typically form over warm tropical and subtropical ocean surfaces, as their formation and intensification rely primarily on the energy provided by the ocean. Pioneering research by Gray (1968) revealed that the formation of tropical cyclones requires the sea surface temperature (SST) to be no less than 26.5℃. Consequently, SST is commonly recognized as a crucial parameter among the environmental factors influencing tropical cyclone formation(Gray, 1979;Emanuel and Nolan, 2004).
