BACKGROUND Nitric oxide (NO) synthesized by endothelial nitric oxide synthase (eNOS) plays a key role in vascular regulation and atherosclerosis, therefore, eNOS may be a candidate gene for ischemic stroke (IS). However, it is still controversial whether eNOS polymorphisms are a risk factor for IS. METHODS Three polymorphisms of the eNOS gene (-922A/G,(More)
PURPOSE Human papillomavirus (HPV) infection plays an important role in the development of cervical cancer, but the prevalence of HPV infection in women of Shenzhen city remains unclear. The present study was performed to describe the change of cervical HPV infection in females who participated in voluntary cervical cancer screening from 2006 to 2010 in(More)
OBJECTIVE To understand the factors related with child restraint system (CRS) use, and provide evidence for the development of appropriate intervention measures to promote the use of CRS for the protection of child passengers' safety. METHODS Self-administrated questionnaire survey was conducted among 0-6 years old children's parents who owned private(More)
BACKGROUND Heat shock protein 70 (HSP70) plays a key role in up-regulating stress responses, and it may be involved in the pathogenesis of ischemic stroke (IS). However, whether HSP70 polymorphisms are a risk factor for IS is still controversial. METHODS Three polymorphisms of HSP70 gene (+190G/C, +1267A/G, and +2437T/C) were analyzed by PCR-RFLP in(More)
Although several studies have documented that latitude might be an effect modifier of the association between temperature and mortality, little is known about how much latitude modifies the temperature-mortality relationship. In this study, we examined this research question using a distributed lag non-linear model and meta-regression analysis based on data(More)
INTRODUCTION Breast cancer is a leading tumor with a high mortality in women. This study examined the spatio-temporal distribution of the incidence of female breast cancer in Shenzhen between 2007 and 2012. METHODS The data on breast cancer incidence were obtained from the Shenzhen Cancer Registry System. To describe the temporal trend, the average annual(More)
Limited information is available on host genetic polymorphisms that confer resistance to HIV-1 infection in Han Chinese who persistently remain seronegative (HEPS) despite high exposure to HIV-1 through unprotected sexual activity with known HIV-1-seropositive spouses or long-term sexual partners. The aim of this study was to investigate the correlation of(More)
PURPOSE High expression of highly upregulated in iver cancer (HULC) has been found associated with increased metastasis and poor prognosis with cancer. This meta-analysis aimed to determine the pooled effect of HULC on metastasis and prognosis of cancers. METHOD The studies were accessed using multiple databases. RevMan5.3 and STATA14.0 were used to(More)
Based on the Rayleigh scattering theory, the radiation forces and the trap stiffness on Rayleigh dielectric sphere induced by a focused Laguerre-Gaussian correlated Schell-model (LGCSM) beam are theoretically studied. It is found that by choosing the appropriate transverse coherence width, mode orders, transverse beam width, and focus lengths, a Rayleigh(More)
