第三产业作为城市化的直接推动力,它的快速发展将掀起西北地区城市化的第二次浪潮。本文从城市化水平与人均第三产业产值及第三产业产值比重的关系、城市规模与人均第三产业产值的关系等角度对西北地区城市化与第三产业的互动关系进行了深入分析,结果表明:(1)西北地区城市化率与人均第三产业产值显著相关;(2)第三产业比重与城市化率的相关性不强;(3)城市辖区人口规模与第三产业规模存在着较显著的相关关系。

Background Cervical cancer is the second most common cause of death from cancer among women worldwide. Human papillomavirus （HPV） plays a central role in the etiology of cervical cancer. It is important to describe the prevalence of HPV infection in different types of cervical lesions and to explore the relation between HPV viral load and the severity of cervical lesions. Methods To describe the HPV infection prevalence and viral load in different age groups, we retrospectively investigated 6405 cases of women who were organized by their units to take health-examination. They were given Hybrid Capture II tests between January 2005 and December 2006. The correlation between HPV viral load and pathology was assessed. Results Overall HPV infection prevalence was 29.1% （1864/6405）, while in women 18-20 years old it was 54.4% （31/57）, the highest among all age groups. After declining rapidly, HPV prevalence stabilized at about 30.0% in women aged 30 and older. Of the 6405 women, 1483 women had a colposcopic biopsy and 33.2% （492/1483） were positive for HPV DNA. Twenty-one percent of women with a normal diagnosis （238/1095） had HPV infection, a statistically significantly lower prevalence than in women with cervical lesions, including those with cervical intraepithelial neoplasia （68.8% in CIN1,66.7% in CIN2, and 76.5% in CIN3） or with cervical cancer （94.1%）. The correlation coefficient between viral load and cervical lesion severity was 0.134, which was not statistically significant （P=0.075）. Viral load values in women with CINs and cervical cancer were calculated, and no significant differences were identified. Conclusions The prevalence of high-risk HPV infection among women attending hospitals for health-examination in Shanghai is similar to the worldwide rate. HPV viral load can distinguish cervical lesions from normal individuals but cannot adequately predict the severity of cervical lesions.
