Objective: To investigate the prevalence of clonorchiasis in Jiangmen City.

Methods: From May to December 2011, each town was randomly chosen from east, south, west, north and central area of 7 cities/districts of Jiangmen City. Four or five villages were randomly selected from each town.

From June to December in 2008, five villages were randomly chosen from Pengjiang District of Jiangmen city and about five hundred residents from each village were examined for clonorchiasis by Kato-Katz method (three slides per specimen). Fifty residents from each village were re-examined one month after treatment. One year later 50 treated residents were chosen from Dalin village and Sanya village for fecal examination.

Aim: To clone and express the gene encoding rat IgE-dependent histamine-releasing factor (rHRF) and to study the effect of recombinant rHRF to induce histamine release from rat sensitized mast cells.

Methods: The complete coding region of rHRF was cloned and expressed in BL21 cells. The soluble recombinant rHRF was purified.
