Iodine-125 brachytherapy for a desmoid tumor in the abdomen-thorax: A retrospective study.

Purpose: To investigate the safety and efficacy of iodine-125 seed implantation in the treatment of abdomen-thorax desmoid tumors (DTs).

Methods And Materials: Data from 14 DT patients who received brachytherapy with iodine-125 seeds were retrospectively collected from 2014 to 2020. The operation was completed using CT guidance and the treatment plan system (TPS).

[Meteorological Formation Mechanisms and Potential Sources of an Ozone Pollution Process in Winter of 2022 in Guangdong Province].

Meteorological conditions play an important role in seasonal ozone variations. In order to understand the meteorological formation mechanisms of ozone pollution in Guangdong Province in winter, the moderate ozone pollution process in Guangdong Province from January 3-6, 2022 was selected for comparison with that in autumn (high pollution season) of 2015 to 2021. The research was based on ground and vertical sounding data and reanalysis data of air quality and meteorological elements.

Performance of low-dose computed tomography on lung cancer screening in high-risk populations: The experience over five screening rounds in Sichuan, China.

Objective: To evaluate the performance of low-dose computed tomography (LDCT) on lung cancer screening in high-risk populations in Sichuan.

Methods: From April 2014 to July 2018, LDCT was performed annually on 3185 subjects aged 50-74 years who had smoked ≥ 20 pack-years (or subjects having quit smoking within 5 years). Information about all deaths and lung cancer diagnoses were obtained by active investigation, or passive matching to disease surveillance system.

Independent and Joint Associations between Serum Calcium, 25-Hydroxy Vitamin D, and the Risk of Primary Liver Cancer: A Prospective Nested Case-Control Study.

Background: Accumulating evidence has shown that serum calcium and vitamin D may be associated with or influence various cancer risks. However, no prospective studies have evaluated the independent and joint associations between prediagnostic levels of serum calcium and vitamin D and future risk of incident primary liver cancer.

Methods: We used a nested case-control design to evaluate subjects over 22 years of follow-up.

The Performance of Immunocytochemistry Staining as Triaging Tests for High-Risk HPV-Positive Women: A 24-Month Prospective Study.

It is urgent to develop an accurate approach to improve the predictive performance of hrHPV-based screening. The aim is to evaluate the performance of p16/Ki-67 and p16/MCM2 staining to triage high-risk human papillomavirus- (hrHPV-) positive women. Cervical specimens were collected from eligible women and tested for hrHPV genotyping, cytology, p16/Ki-67, and p16/MCM2 staining at baseline.

Clinical efficacy of computed tomography-guided iodine-125 seed implantation therapy for patients with metastatic epidural spinal cord compression: A retrospective study.

Background: This study evaluated the clinical efficacy of computed tomography (CT)-guided radioactive iodine-125 ( I) seed implantation in patients with metastatic epidural spinal cord compression (MESCC).

Materials And Methods: A cohort of 22 patients with MESCC were retrospectively enrolled. All patients underwent CT-guided I seed implantation therapy via standard procedures.

A direct comparison of four high-risk human papillomavirus tests versus the cobas test: Detecting CIN2+ in low-resource settings.

Low-cost, accurate high-risk human papillomavirus (HR-HPV) tests are needed for cervical cancer screening in limited-resource settings. More than 200 cervical cytological specimens from hospital patients were collected and analyzed for a real-world study. We evaluated the analytical and clinical performance of four widely used HR-HPV test (Tellgen, Hybribio, Liferiver, and Sansure) based on real-time polymerase chain reaction technology platforms, compared with the cobas test.

Human Papillomavirus (HPV) 16/18 E6 Oncoprotein Expression in Infections with Single and Multiple Genotypes.

Factors that differentiate risk of cervical cancer associated with infection with single versus multiple HPV types are yet undefined. We hypothesize that E6 oncoprotein is one determining factor. This cross-sectional, multicenter study was performed between 2013 and 2017.

Assessment of the cancer risk factors of solitary pulmonary nodules.

There are no large samples or exact prediction models for assessing the cancer risk factors of solitary pulmonary nodules (SPNs) in the Chinese population. We retrospectively analyzed the clinical and imaging data of patients with SPNs who underwent computer tomography guided needle biopsy in our hospital from Jan 1st of 2011 to March 30th of 2016. These patients were divided into a development data set and a validation data set.

[Study on air quality and pollution meteorology conditions of Guangzhou during the 2010 Asian games].

Based on the monitoring data of NO2, O3, SO2, PM, visibility, regional air quality index (RAQI) and the atmospheric transport and diffusion data from Nov. 4, 2010 to Dec. 10, 2010 in Guangzhou area, the variations of air quality and meteorological conditions during the Guangzhou Asian Games were analyzed.
