Article Synopsis
- Timely analysis of cancer incidence trends in China is essential for effective prevention and control strategies, particularly given the rising rates of certain cancers.
- This study examined cancer data from 1983 to 2017 across 32 types to identify trends and project future rates until 2032, focusing on factors like aging and lifestyle risks.
- Findings revealed significant increases in cancers such as thyroid (highest rise), prostate, and cervical, with projections indicating more cases due to risk factors, despite some declines in others like stomach and liver cancers.
Article Synopsis
- * Results indicate rising cases of specific cancers, including thyroid and kidney, particularly among younger age groups, as well as an increasing prevalence of obesity-related cancers in the 0-14 and 15-39 age groups.
- * The cancer landscape in China is shifting to resemble that of developed nations, with increasing rates in cancers such as cervical and prostate cancer, highlighting the urgent need for preventive measures and healthier lifestyle choices, especially among younger populations.
Introduction: Since 2006, the human papillomavirus (HPV) vaccine has been recommended for females aged 9-26 years in the United States. Aiming to evaluate the early effect of the HPV vaccine on cervical cancer, this study assessed the incidence of cervical cancer by age and histology before and after the introduction of HPV vaccination.
Methods: Data on cervical cancer incidence from 1975-2019 were extracted from the Surveillance, Epidemiology, and End Results Program.
Article Synopsis
- The study investigates the differences in lung cancer incidence between males and females in China and the United States, noting how these trends vary due to population and environmental factors.
- Data from 1978 to 2012 were analyzed, showing declining incidence rates for males in China and stable rates for females in the U.S., but rising trends for young females in China.
- Predictions indicate that gender disparities in lung cancer incidences will narrow, potentially leading to higher incidence rates for females in the U.S. than males by 2023-2027, highlighting the need for further research among women in China.
Background Retrospective or single-center prospective studies with relatively small samples have shown that contrast-enhanced US (CEUS) can improve the diagnostic accuracy of percutaneous biopsy, but larger prospective studies are lacking. Purpose To assess the diagnostic performance of CEUS-guided biopsy (CEUS-GB) of focal liver lesions (FLLs) compared with US-guided biopsy (US-GB) in a prospective multicenter study. Materials and Methods In this randomized controlled study conducted in nine hospitals in China between March 2016 and August 2019, adult participants with FLLs detected with US, CT, or MRI and planned for percutaneous biopsy were randomly assigned to undergo either US-GB or CEUS-GB.

The aim of this study was to analyze potential age, period, and cohort effects on the incidence of thyroid cancer in mainland China and to predict new cases up to 2032.
Methods: We calculated age-adjusted and age-specific incidence rates of thyroid cancer, conducted an age-period-cohort analysis of 35,037 thyroid cancer incidence cases reported to Cancer Incidence in Five Continents from 1983 to 2012 in mainland China, and predicted incidence up to 2032 using the Bayesian age-period-cohort method.
[Single trial classification of motor imagery electroencephalogram based on Fisher criterion].

In order to realize brain-computer interface (BCI), optimal features of single trail motor imagery electroencephalogram (EEG) were extracted and classified. Mu rhythm of EEG was obtained by preprocessing, and the features were optimized by spatial filtering, which are estimated from a set of data by method of common spatial pattern. Classification decision can be made by Fisher criterion, and classification performance can be evaluated by cross validation and receiver operating characteristic (ROC) curve.
