Objective To investigate the MR imaging technique and features of acute radiation- induced hepatic injury with superparamagnetic iron oxide(SPIO)enhancement in a rabbit model.Methods On the 10th day after half-liver single 40 Gy X-ray irradiation,MR imaging before and after SPIO administration and pathologic study of 12 adult rabbits were performed.Results On the 10th post-irradiation day,TSE T_2 WI before SPIO enhancement,the irradiated liver of two rabbits showed relatively higher signal, and 1 showed slightly lower signal.With SPIO enhancement,the irradiated livers of 9 rabbits were found to be abnormal,manifesting as higher or slightly higher areas on multiple MR imaging sequences,especially the TFE T_1 WI sequence.Histological specimen with HE stain under light microscopy revealed occlusive injury of central veins(veno-occlusive disease,VOD)in each irradiated liver to some extent.Electron microscopy investigation of the irradiated liver disclosed intracellular edema,fibrin deposition,and widening of the Disse-space.Conclusion The early pathologic feature of the irradiated liver is occlusive injury of the central vein.MR imaging with SPIO enhancement is effective to valuate the early irradiation-induced liver injury.

Fourteen psychrotrophic bacteria were isolated from swamp soil collected in Ruoergai plateau wetland,and their generation time and degrading ability of livestock wastewater CODcr was determined.The results showed that the generation time was within 4.9 h to 11.6 h.Based on the generation time,9 psychro-trophic strains(NLJ1,NLJ6,NLJ7,NLJ9,NLJ10,NLJ11,NLJ12,NLJ13 and NLJ14),whose generation time was within 4.9 h to 5.6 h,were chosen to treat livestock wastewater.The results suggested that these 9 strains had different CODcr disposal ability when treating livestock wastewater singly at 6?C for 6 h,and strains NLJ6,NLJ7,NLJ9,NLJ10,NLJ11 and NLJ13 had good ability to degrade livestock wastewater,the CODcr degrading rate was about 60%~70%,hence,they were used as high efficient strains;However,the CODcr degrading rate of the other strains was less than 50%.After inoculating mixture culture of these six strains into the distilled livestock wastewater,after 6 h's treating,the CODcr degrading rate reached to 85.42%.Furthermore,activated sludge collected from Yaan,Dujiangyan and Chengdu were inoculated by the mixture culture of those six strains,and used to treat livestock wastewater for 6 h.The results showed that the average CODcr degrading rate was 81.67%,76.32% and 70.56%,respectively;Variance analysis showed that there was no significant differentiation between each treatment,which revealed that those six psychrotrophic strains had good adaptability to different source of activated sludge.

BackgroundWith the increasing prevalence of dry eye and the continuous improvement of living standards,the problem of dry eye more and more get the attention of people.At present,China still lacks the large population-based epidemiological data of dry eye. Objective To investigate the prevalence and possible risk factors of dry eye in a community of Huidong County of population aged 14 and over.Methods From September 2010 to January 2011,using questionnaires and examination of dry eye related,2800 people were selected randomly for cross-sectional survey.Those suspected as dry eye were examed by the SchirmerⅠtest ( S Ⅱ T),tear-film breakup time(BUT),corneal fluorescein staining(F1).Results In the 2475 questionnaire effectively,154 persons were diagnosed as dry eye,and the prevalence rate of dry eye was 6.22％,8.06％in females,4.14％in males.The prevalence rate increases with age.The S Ⅰ T and BUT decreased with increasing age.S Ⅰ T and BUT in females are less than males.Foreign body sensation is the primary complaints of patients.Logistic analysis showed that the most common risk factors in dry eye are age and gender.The system disease and eye diseases,eye fatigue and long exposure to dust are also main determinants.ConclusionsThe population prevalence rate of dry eye increased with age,the prevalence rate of dry eye in females is higher than that in males.The key factors associated with dry eye are age,gender,systemic disease and eye diseases,occupation,working environment.

Mantidis Oötheca is commonly used Chinese medicine. Because of the used medicinal part is oötheca and many mantis species can yield ootheca, it is not possible to identify its original animal accurately. There is no unanimous conclusion about the corresponding relationship between Mantis and Mantidis Oötheca (Sangpiaoxiao). This relationship is the basis of the Mantidis Oötheca research. Our study combined the methods of artificial incubation oötheca and capture the living mantis to identify the species of Mantis and Mantidis Oötheca. The results showed that the origin insects of Mantidis Oötheca was Tenodera, Hierodula and Statilia genus insects. This has laid a foundation for further study of Mantidis Oötheca.
