Objective To investigate the prevalence of clonorchiasis among residents of Huachuan Country,Heilongjiang Province and to provide a basis for development of control strategies.Methods From 2011 to 2012,cluster random sampling was performed to survey the incidence of clonorchiasis in Huachuan Country.Fecal specimens were collected and examined the clonorchis sinensis eggs by Kato-Katz method.A questionnaire survey was conducted to collect related information such as age,gender,occupation and eating habits.The infection characteristic was analyzed.Results Totally 884 patients with clonorchiasis were found among 2248 residents,and the infection rate was 39.32％.The infection rate in male[47.15％(611/1296)] was significantly higher than females [28.68％(273/952),x2 =34.55,P ＜ 0.01].The infection rate increased with age,which was higher in the 20-69 years old people,with the highest infection rate in the 50-59 years old groups[45.34％ (219/483)].Of the occupational distribution,farmers had the highest infection rate [47.24％ (420/889)],followed by cadres and staffs[38.38％(190/495)].Of residents with fresh fish eating history,the prevalence of clonorchiasis was 53.38％(150/281).Conclusions The prevalence of clonorchiasis is still high in Huachuan County.To reduce the prevalence of clonorchiasis,comprehensive prevention measures,health education and group chemotherapy should be carried out.

To establish a method of directional differentiation and efficient production of neurons from embryonic stem cells (ES cells) in vitro, based on the 4-/4+ protocol described by Bain, a new method was established to induce ES cells differentiating into neurons by means of three-step differentiation using all-trans retinoic acid (ATRA) combined with astrocyte-conditioned medium (ACM) in Vitro. The totipotency of ES cells was identified by observation of cells' morphology and formations of teratoma in immunocompromised mice. The cells' differentiation was evaluated continuously by the detection of the specific cellular markers of neural stem cells, neurons and astrocytes, including nestin, NSE and GFAP using immunohistochemistry assay. The NSE positive cells' ratio of the differentiated cells was determined by flow cytometry. It was found that the transparent circular clusters surrounding embryoid bodies induced with combining induction protocol formed just after 24 h and gradually enlarged later. This phenomenon could not be observed in EBs induced only by ATRA. The NSE positive cells' ratio in the cells induced with ATRA and ACM was higher than that of the cells induced by ATRA at different time points of differentiation, and finally reached up to 73.5% among the total differentiated population. It was concluded that ES cells could be induced into neurons with high purity and yield by means of inducing method combining with ATRA and ACM.
