Objectives To describe the incidence and determinants of survival of patients with nasopharyngeal lymphoma (NPL) between 1973 and 2012 using the Surveillance, Epidemiology, and End Results (SEER) database. Study Design Retrospective cohort study using a national database. Methods The SEER registry was used to calculate survival trends for patients with NPL between 1973 and 2012. Patient data we...
The problem of the Chinese financial system with non performing loans is significant and murky. If China's non performing loan problem exists on a certain level of severity and is not trending toward a more manageable state, then China could be moving toward financial crisis. Empirical and theoretical studies in recent years have implied that this might be the case. It might be impossible to co...
Genetic factors play a major role in the aetiology of idiopathic generalised epilepsies (IGEs). The present genome scan was designed to identify susceptibility loci that predispose to a spectrum of common IGE syndromes. Our collaborative study included 130 IGE-multiplex families ascertained through a proband with either an idiopathic absence epilepsy or juvenile myoclonic epilepsy, and one or m...
A comprehensive review for the in-air calibration of an Ir-192 high-dose-rate brachytherapy source in terms of air kerma strength (AKS) and reference air kerma rate (RAKR) using the Farmer chamber was conducted. The reviewed calibration methods include the National Physical Laboratory (NPL) calibration standard in the UK, the 7-distance technique with the standard calibration of the National In...
To investigate the relationship between 12 candidate genes responsible for water regulation, sodium metabolism and membrane ion transport and essential hypertension (EH) in the Chinese. Linkage analysis of EH was performed in 95 Chinese nuclear families including 477 subjects using a technique of fluorescence-based gene scanning with 12 microsatellite markers. Markers were selected on the chrom...
Parametric and nonparametric statistical methods have been applied to the alcohol dependence dataset collected in the Collaborative Study on the Genetics of Alcoholism (COGA). Our nonparametric linkage analyses (NPL) were based on the Sall statistic of GENEHUNTER [Kruglyak et al., 1996] and the improved NPL statistic of GENEHUNTER-Plus [Kong and Cox, 1997]. Based on likely regions for alcohol s...
A Strategic Research project was performed at NPL with the aim of investigating issues and potential improvements for light-ion dosimetry. The objectives of the project were: a literature survey, testing a number of dosimeters in the proton therapy beam of Clatterbridge Centre of Oncology (CCO), measurement of dose distributions, measurement and calculation of detector perturbations, explore th...
OBJECTIVES To identify the loci involved in nonsyndromic cleft lip with or without cleft palate (NSCL/P) in Northern Chinese people in Shenyang by using genomewide and interaction linkage scan. METHODS Two multiplex families in Shenyang from North China were ascertained through probands with NSCL/P. Blood of every member was drawn for DNA extraction and analysis. Genotypes were available for ...
Gliomas, which generally have a poor prognosis, are the most common primary malignant brain tumors in adults. Recent genome-wide association studies have shown that inherited susceptibility plays a role in the development of glioma. Although first-degree relatives of patients exhibit a two-fold increased risk of glioma, the search for susceptibility loci in familial forms of the disease has bee...
