ABSTRACT
ABSTRACT CONTEXT: Inflammatory myofibroblastic tumors are a rare type of soft-tissue tumor. Inflammatory myofibroblastic tumors are characterized by rearrangements involving the anaplastic lymphoma kinase gene locus on 2p23. Case Report: We report the case of a 67-year-old Chinese male who presented with dysuria and fever. Magnetic resonance imaging showed an irregular prostatic mass with an isointense signal and obscure boundary. Histopathological evaluation showed that the mass consisted mainly of spindle-shaped cells. Immunohistochemical evaluation showed that the tumor cells were negative for anaplastic lymphoma kinase. CONCLUSIONS: Inflammatory myofibroblastic prostate tumors are rare lesions with unclear etiology. The pathological diagnosis is very important.

Objective To explore the expression characteristics of cytochrome P450(CYP)candidate genes(CYP6M3, CYP6Y1,CYP6P5,CYP4H14,CYP4G17,CYP12F16)in Anopheles sinensis.Methods The samples were collected from dif-ferent developmental stages(eggs,larvae,pupae and adult mosquitoes(females and males)),and different tissues(salivary glands,malpighian tubes,midguts,ovaries,and fat bodies)of An.sinensis and the female adult mosquitoes exposed by differ-ent insecticide doses(0,1.25,3.75,6.25,12.5μg/bottle)and time points(0,5,15,30,60 minutes),then the total RNA was extracted. Quantitative reverse transcription PCR(qPCR)assay was used to analyze the relative expressions of six CYP genes in An.sinensis at different developmental stages,tissues and different insecticide exposure doses and time.Results The expressions of CYP6M3 and CYP6Y1 in the male adult mosquitoes were the highest,the expression of CYP6M3 gene in the males was 35.1 times higher than that in the females,the expression of CYP6Y1 in the males was 61.4 times higher than that in the females;the expression level of CYP4H14 in the larvae was the lowest,the expression of CYP4H14 in the females was 22.5 times higher than that in the fourth instar larvae.The expressions of candidate CYP genes in different tissues of An.sinensis were significantly different,the expression of CYP6M3 in the malpighian tubule was 38.9 times higher than that in the ovary,the ex-pression of CYP6Y1 in the fatbody was 9.1 times higher than that in the ovary,the expression of CYP4G17 was 4.6 times higher than that in the ovary,and the expression of CYP12F16 was 4.4 times higher thanthat in the ovary.The exposure to different in-secticide doses and time showed some induction effects in the expressions of candidate CYP genes,which affected the expres-sions of candidate CYP genes in An.sinensis.Conclusion The expression of candidate CYP genes varies significantly in differ-ent developmental stages and various tissues of An.sinensis,and exposure to deltamethrin at various doses and time points af-fects CYP genes expression in An.sinensis.
ABSTRACT
Objective To understand the status of knowledge awareness rates and influencing factors of clonorchiasis among the residents in 4 counties(cities)of Hunan Province,so as to provide the references for formulating the prevention and control strategy of clonorchiasis in the province. Methods A total of 1224 subjects were selected by the multi-stage cluster sampling method and investigated with questionnaires and face-to-face interviews. Results The clonorchiasis knowledge awareness rates of the residents were 15.67% in Yongzhou City,9.94% in Yueyang City,13.25% in Wangcheng County,and 21.96% in Tongd-ao County,respectively. In the whole province,the clonorchiasis knowledge awareness rates of the residents were 44.67%, 56.43%,60.95%,and 42.46% in the etiology,clinical manifestations,epidemiological characteristics and daily prevention,re-spectively. The logistic regression showed that the influencing factors of clonorchiasis knowledge awareness rates were the daily dining place,whether or not having the medical personnel in the family,the degree of attention to the relevant news reports, and the history of parasitic diseases. Conclusions The level of clonorchiasis than that in other areas,but the overall level of clonorchiasis knowledge awareness of the residents in Hunan Province is not high. Therefore,the relevant authority should strengthen the health education in clonorchiasis prevention knowledge including personal daily food hygienic knowledge. knowl-edge awareness rate of the residents in the west-southern areas of Hunan Province is higher
