Comprehensive Evaluation on Urban Sustainable Development of Harbin City in Northeast China

It is an effective way in realizing urban coordinated and sustainable development to establish a series of in- dicators and to evaluate urban environmental and socioeconomic development. According to the characteristics of Harbin City in Northeast China, an indicator system including five subsystems and 37 indicators was established for comprehensive evaluation on urban sustainable development. The development indexes of all urban subsystems and complex system were calculated quantitatively using the comprehensively integrated methods composed of Principle Component Analysis, Analytic Hierarchy Process and weighed index method, and then the comprehensive level of ur- ban sustainable development and the degree of urban interior coordination were analyzed. The results indicated that 1) the overall urban development presented an uptrend, however, the interior development was not well balanced from 1996 to 2006; 2) the development in each subsystem presented a strong fluctuation; and 3) the development in re- sources subsystem showed a downtrend. Based on those results, the suggestions of urban sustainable development were put forward at the end.

妊娠晚期孕妇高危型HPV感染及危险因素分析

目的:探讨妊娠晚期孕妇高危型人乳头瘤病毒(HPV)感染情况并分析危险因素。方法:2017年1月—2020年12月在本院产科门诊进行HPV筛查及HPV分型检测的妊娠晚期孕妇4600例,通过调查问卷、临床资料分析等方式进行流行病学调查,分析相关危险因素。结果:发放调查问卷4600例,收回有效问卷4469例,有效率为97.2%。4469例中434例感染高危型HPV(9.7%)。感染率较高的高危型HPV亚型为HPV16(1.4%)、HPV52(1.2%),感染单一型为61.8%,双重型为23.7%,多重型为14.5%。单因素分析显示,孕妇年龄、孕次、首次妊娠年龄、孕期性行为、性伴侣、爱人婚外关系、宫颈炎、阴道分泌物异常是妊娠晚期孕妇高危型HPV感染风险(P<0.05),孕妇年龄、产次、吸烟史、饮酒史、尿路感染等因素无差异(P>0.05)。logistic逐步回归分析显示,孕期性行为、性伴侣、爱人婚外关系、宫颈炎是妊娠晚期孕妇感染高危型HPV的独立危险因素(P<0.05)。结论:本次调查高危型HPV感染优势亚型为HPV16和HPV52。可针对本地区感染高危型HPV危险因素加强孕妇的宣传干预。
