A total of 260 surface soil samples were collected to investigate the spatial distribution of trace metals in Guangdong province, one of the fast developing regions in China. The results show that the upper baseline concentrations of Cu, Pb, Zn, Cd, Ni, Cr, and Hg were 28.7, 57.6, 77.8, 0.13, 23.5, 87.0, and 0.15 mg kg(-1), respectively. Regional parent(More)

A total of 260 soil profiles were examined to investigate the spatial distribution of total soil selenium (Se) in Guangdong province, China. In the investigated area, the soil Se concentrations follow an approximately lognormal distribution. The soil Se geometric mean concentration of 0.23 mg kg(-1) is higher than that of Chinese soils; however, Se(More)
A total of 260 soil profiles were reported to investigate the fluoride distribution and vertical variation in Guangdong province. The soil fluoride contents followed an approximately lognormal distribution. Although the soil fluoride geometric mean concentration of 407 mg/kg is lower than that of China, its content varied from 87 to 2860 mg/kg. An upper(More)
1860 Vol 388 October 15, 2016 In 1963, China’s medical teams became its signature programme for international health outreach work. 15 years later, the so-called barefoot doctor approach for training locals in basic medical care inspired the global primary health care initiative at Alma-Ata. Since 2015, China has launched a series of(More)
INTRODUCTION Schizophrenia is a severe, chronic and disabling mental illness. Non-adherence to medication and relapse may lead to poorer patient function. This randomised controlled study, under the acronym LEAN (Lay health supporter, e-platform, award, and iNtegration), is designed to improve medication adherence and high relapse among people with(More)
Long-term therapy should be administrated for patients with schizophrenia and the medication adherence is very important for the prognosis and outcome in these patients. In this study, we screened the literatures from various databases in accordance with our search criteria. A total of 11 literatures with the results of reliability and validity regarding(More)
