BACKGROUND AND AIMS Current cardiovascular disease (CVD) prevention is based on diagnosis and treatment of specific disease. Little is known for high risk people with CVD at the community level. In rural China, health records of all residents were established after the recent health reforms. This study aims to describe the characters of the rural population(More)
OBJECTIVES To estimate the relationship between exposure to extremely low-frequency electromagnetic fields (ELF-EMF) and the risk of amyotrophic lateral sclerosis (ALS) by a meta-analysis. METHODS Through searching PubMed databases (or manual searching) up to April 2012 using the following keywords: "occupational exposure", "electromagnetic fields" and(More)
BACKGROUND Cardiovascular disease (CVD) is a major cause of death in China. Despite government efforts, the majority of hypertensive and diabetic patients in China do not receive proper treatment. Reducing CVD events requires long-term care that is proactive, patient-centred, community-based, and sustainable. We have designed a package of interventions for(More)
BACKGROUND Type 2 diabetes is associated with acute and chronic complications and poses a large economic, social, and medical burden on patients and their families as well as society. OBJECTIVE This study aims to evaluate the direct economic burden of type 2 diabetes in China. DATA SOURCE systematic review on cost of illness, health care costs, direct(More)
OBJECTIVE Previous studies have found that overweight and obesity are related to numerous diseases, including thyroid cancer and thyroid volume. This study evaluates the relationship between body size and the presence of thyroid nodules in a Chinese population. METHODS A total of 6793 adults and 2410 children who underwent thyroid ultrasonography were(More)
BACKGROUND Diabetes case finding based on structured medical records does not fully identify diabetic patients whose medical histories related to diabetes are available in the form of free text. Manual chart reviews have been used but involve high labor costs and long latency. OBJECTIVE This study developed and tested a Web-based diabetes case finding(More)
Functional dyspepsia (FD) is a functional gastrointestinal disorder diagnosed by symptom-based criteria. It has been said that duodenal immune activation plays a role in the pathogenesis of FD. The primary aims of the study were to compare the total number of duodenal eosinophil and evaluate the eosinophil degranulation rate, number of duodenal degranulated(More)
OBJECTIVE To explore the effects of radiofrequency-electromagnetic fields (RF-EMFs) from mobile phones on depression and anxiety after titanium mesh cranioplasty among patients with traumatic brain injury (TBI). METHODS Two hundred and twenty patients with TBI and titanium mesh cranioplasty who were hospitalized from 2008-2012 were recruited in this(More)
BACKGROUND Resistance to intravenous immunoglobulin (IVIG) occurs in 10-20% of patients with Kawasaki disease (KD). The risk of resistance is about two-fold higher in patients with elevated gamma glutamyl transferase (GGT) levels. We sought to understand the biological mechanisms underlying IVIG resistance in patients with elevated GGT levels. METHOD We(More)
BACKGROUND Hypertension, with a global prevalence of 40%, is a risk factor for cardiovascular diseases (CVD). We conducted an exploratory study in Zhejiang China to understand the prevention of CVD among hypertensive patients with a 10 year CVD risk of 20% or higher. We assessed current practices in a rural 'township hospital' (a primary care facility), and(More)
