Objective To investigate the effect of up-regulating miR-34c-5p on cloning formation and migration of nasopharyngeal carcinoma cell line HONE-1 in vitro. Methods Expression levels of miR-34c-5p in nasopharyngeal cell line NP69 and nasopharyngeal carcinoma cell line HONE-1 were investigated by real time quantitative PCR;Cloning Forma?tion Test and Transwell Migration Assay were used to explore the effect of up-regulating miR-34c-5p on proliferation and migration of nasopharyngeal carcinoma cell line HONE-1. Results The expression of miR-34c-5p in nasopharyngeal car?cinoma cell line HONE-1 was lower than that in normal nasopharyngeal cell line NP69. Up-regulating miR-34c-5p signifi?cantly suppressed the cloning formation and migration capacity, compared to those of NP69 cell line and HONE-1 with nor?mal level of miR-34c-5p(P<0.05). Conclusion Down-regulating miR-34c-5p involve in proliferation and migration of nasopharyngeal carcinoma and may be a used as a new therapeutic target for nasopharyngeal carcinoma.

Objective To study on the effect of indicator animals in plague surveillance throngh detecting F1 antibody against Yersiniapestis(Y.pestis)in indicator animals in wild rat plague foci,provide scientific evidence for plague control and determining the range of epidemic area.Methods According to investigation scheme of wild rodents plagne foci in Yunnan Province,indicator animals Canis familiarils and Felis catu(C.familiarils and F.catus)related to the plague were investigated in 75 villages,14 township and 10 counties around Yulong County,and living rodents were captured by cage,sera of indicator animals and rodents relevant to plague were simultaneously collected and detected for F1 antibody against Y.pestis using indirect hemagglutination(IHA).Results Seropositivity rate of indicator animals were 6.76%(202/2987),being 24.69% in C.familiaris and 24.69% in F.catus,there were statistical significance(X2＝87.32,P＜0.01)between C familiaris and F catus,the latter beingmore than the former.But F1 antibody of rodents sera were not detected,its seropositivity rate was zero.there was a statistical significance(P＜0.01)between indicator animals and rodents.Conclusions Through serocpidemiological survey of indicator animals,new wild rat plague natural focus has been confirmed in YuLong County and Gucheng District in LiJiang City,therefore,serocpidemiological surveillance of indicator animals is very important for plague control and prevention.

Background Placement of an orbital implant is a main way to prevent orbital atrophy with aging.But its mechanism is under clear.Researchs showed that bone growth factors play important role during the development and repair of bone,especially transforming growth factor-β1(TGF-β1).Objective Present study was to investigate the expression of TGF-β1 protein in orbital bone after enucleation or enucleation with placement of an orbital implant and its function in the mechanisms of preventing and treating the orbital malformed development after enucleation with placement of an orbital implant.Methods Twenty-one age- and weight-matched New Zealand white young rabbits were randomly divided into the enucleation,implant and control groups,and each group including seven rabbits.Eyeball nucleation surgery was performed in the left eyes of 7 1-month-old rabbits,and a spherical orbital implant was inserted after enucleation of the left in matched rabbits in implant group.The left eye of normal rabbits served as controls.The rabbits were sacrificed in 1 month after surgery.The expression of TGF-β1 protein in the left orbital bone was detected using enzyme immunoassay and FITC labelling immunoassay technique in the sections of zygomatic bones.The content of TGF-β1 protein in the left orbital bone tissue was measured by ELISA method.This use of animals complied with the Regulations for the Administration of Affair Concerning Experimental Animals by State Science and Technology Commission.Results The height and width of orbital in enucleation group were significantly lower than those of implant and normal control groups(height:P=0.00,P=0.00;width:P =0.00,P=0.00).The positive bone cells of both enzyme immunoassay and FITC staining were increased in the implant and control groups in comparison with enucleation group,but the positive response intensity for TGF-β1 was resembled between implant group and control group.ELISA result revealed that the content of TGF-β1 protein in bone tissue was significantly lower in the enucleation group than in implant and control groups(P=0.00,P=0.00).The expression and content of TGF-β1 protein in bone tissue is similar between the implant group and the control group(P=0.41). Conclusion The experiment results indicate that TGF-β1 protein participate in the orbital development.TGF-β1 played important role in the prevention and treatment of enucleation-induced orbital malformation in the eye with placement of an orbital implant.

Objective To investigate the distribution of water-borne fluoride and the current situation of endemic fluorosis in Yan'an city in 2006, and to evaluate the effect of water defluoridation project by improving driking water quality. Method In 2006 in Yan'an city, 5 samples from water source were collected in each selected village that was chosen according to 5 directions of East, West, South, North, and Central. Meanwhile, 1 sample from water source, 1 sample from water processing factory and 2 tap water samples were collected from each water defluoridation project. Water fluoride was determined by spectrophotometric method, teeth and skeletal fluorosis examination were performed by Dean method and "national criteria of endemic skeletal fluorosis diagnosis of China" in children aged 8-12 year and adults, respectively if water fluoride level > 1.00 mg/L Results Of 726 water samples from 293 villages tested, samples from 25 villages had higher fluoride( > 1.00 mg/L), and these villages covered a population of 11 610 people and most of these people were in Wuqi and Yanchuan counties. Water fluoride ranged from 0.10 mg/L to 3.50 mg/L, with median being 0.59 mg/L. Of 100 water samples from 25 water defluoridation projects, only 1 sample exceeded the national criteria in Yanchuan, and Wuqi counties, respectively,with fluoride level being 1.85 mg/L and 1.60 mg/L, respectively, and population exposed was 3083 and 708, respectively, with water fluoride ranged 0.30 - 2.00 mg/L In the examination of 1281 children aged 8 - 12, we detected 238 cases of dental fluorosis, and the detection rate reached 18.58%; 13 900 adults were checked, and 375 cases were confirmed of skeletal fluorosis, a detection rate reached 2.70%. Conclusions Yan'an has a wide range of water with high fluoride and severe fluorosis people. The water defluoridation projects need to be further improved. The task of prevention of endemic fluorosis is still arduous, and we should speed up the implementation of comprehensive water defluoridation measures.
