[Spatial epidemiological study on malaria epidemics in Hainan province].

Article Synopsis
- The study aimed to analyze the spatial distribution of malaria epidemics in Hainan province and examine how environmental factors affect these outbreaks while also creating a predictive model for malaria incidences.
- Data on malaria rates and environmental factors were gathered across 19 counties in Hainan from May to October 2000, and various correlations were calculated using statistical software.
- Results indicated that higher malaria incidence correlated positively with elevation and land covered by forests and grasslands, but negatively with urban areas and land surface temperatures; a predictive model was developed using negative binomial regression analysis.
Aim: To detect the common intestinal pathogenic bacteria quickly and accurately.
Methods: A rapid (<3 h) experimental procedure was set up based upon the gene chip technology. Target genes were amplified and hybridized by oligonucleotide microarrays.

Objective: To investigate the effect of low intensity and very high frequency (VHF) electromagnetic radiation (170 MHz) on nervous system function and serum enzymes and immune function in human subjects with occupational exposure to VHF.
Methods: To measure the intensity of VHF and other environmental factors on the spot, to hold the questionnaire about chief complaints, to examine the rheoencephalography and the neurobehavior function, to analyze ALT, AST, ALP and LDH, and IgA, IgM and IgG in experimental group and control group.
Results: The intensity of VHF (direction of antenna: 0 degrees, 10 m and 135 degrees, 20 m) was higher than that of national standard on-the-spot.
