Knowledge of human papillomavirus vaccination and related factors among parents of young adolescents: a nationwide survey in China.

Purpose: To investigate the human papillomavirus (HPV) vaccine-related knowledge and factors associated with the knowledge among parents of young adolescents in China.

Methods: The study was based on data of a survey carried out in seven geographic regions of China. Parents of students in junior middle school were surveyed during parents' meetings.

Human papillomavirus vaccine awareness, acceptability, and decision-making factors among Chinese college students.

Background: College students are recommended as the target groups for catch-up human papillomavirus (HPV) vaccination. Systematical exploration of awareness, acceptability, and decision-making factors of HPV vaccination among Chinese college students has been limited.

Materials And Methods: A multi-center survey was conducted in mainland China between November 2011 and May 2012.

Quantitative study of iron metabolism-related genes expression in rat.

Objective: To investigate the multiple iron metabolism-related genes expression, its regulation by iron and the expression correlation among the genes in rat tissues.

Methods: Two groups (n=30) of Sprague-Dawley female weanling rats were fed with a control diet and an iron deficient diet respectively for 4 weeks. All rats were then sacrificed, and blood and tissue samples were collected.

Divalent metal transporter 1 expression and regulation in human placenta.

Divalent metal transporter 1 (DMT1) is likely responsible for the release of iron from endosomes to the cytoplasm in placental syncytiotrophoblasts (STB). To determine the localization and the regulation of DMT1 expression by iron directly in placenta, the expression of DMT1 in human term placental tissues and BeWo cells (human placental choriocarcinoma cell line) was detected and the change in expression in response to different iron treatments on BeWo cells was observed. DMT1 was shown to be most prominent near the maternal side in human term placenta and predominantly in the cytoplasm of BeWo cells.

Prognostic analysis of ovarian cancer patients using the Cox regression model.

Background And Objective: Ovarian cancer is one of the most common causes of death among gynecological malignancies. This study was to investigate the prognostic factors for ovarian cancer using the Cox regression model.

Methods: Data of 103 patients, initially operated at Shaanxi Tumor Hospital from 1999 to 2004, were retrospectively analyzed.

[Fourier transform infrared spectroscopy study on normal and malignant tissues of cervix].

Fourier transform infrared spectroscopy (FTIR) was used to investigate 35 cervical tissues , including 17 squamous cell carcinoma of cervical samples, and 5 adenocarcinoma of cervical samples, 13 normal cervical samples. The results show that there are 18 spectral bands with highly appearance percentage(>80%) in these three types of tissues, and these spectral bands may be the characteristic infrared spectra bands for cervical tissues; Some of relative absorbance ratios are statistically significant (p < 0.05) among these three types of tissues.
