Objective To evaluate different measurement methods in histogram for the diffusion and perfusion parameters from intravoxel incoherent motion (IVIM) MR imaging of different types of uterine fibroids.Methods 63 patients with confirmed uterine fibroids (80 in total) were examined with MR imaging.3D T2WI and IVIM imaging were performed for those patients.The fibroids were classified into three types (type 1, 2, 3) on the basis of different signal intensities on T2WI according to Funaki's theory.Real diffusion coefficient (D), pseudodiffusion coefficient (D*) and perfusion fraction (f) were calculated using IVIM analysis.25%,50% and 75% of those parameters (D25,D50,D75,D*25,D*50,D*75,f25,f50 and f75) as well as mean values (Dmean,D*mean and fmean) were calculated using histogram method.ANOVA was used to compare the IVIM parameters among the three types of fibroids.Results There were 44 type 1,24 type 2 and 12 type 3 fibroids in the total of 80 fibroids.There was significant difference among all the diffusion parameters from histogram and mean values of different types of fibroids, and only one perfusion parameter D*75 value showed significant difference (P<0.05).There was no significant difference among all the f values from histogram and mean values.Conclusion Different measurements of parameters from IVIM histogram showed no added value for diffusion features in different types of fibroids compared to mean value.While the perfusion parameter D*75 value from histogram can distinguish the features of perfusion within different types of fibroids compared to mean value.

Objective To investigate the relationship between gliosis, synaptic reorganization and the mechanism of chronic temporal lobe epilepsy induced by kainic acid. Methods The mossy fibers sprouting, synaptic reorganization and gliosis were observed by Neo-Timm staining and immunohistochemical staining respectively. Results The injected (ipslateral) side was injured predominantly in the CA 3 subfield and hilus, whereas the CA 1 subfield was injured mildlyThe contralateral side showed pathological changes mainly in the CA 1 subfield and hilus, and moderately in the CA 3 subfieldThe longer the rats survived, the more obvious changes were observed in the hippocampuses. Conclusion The injection of kainic acid in hippocampus can cause neuronal loss, reactive gliosis and plasticity of neurons, probably form the abnormal neuronal discharge circuit, finally induce the seizures

Objective To discuss the difference of levels of serum and urinary iodine and thyroid function in painless thyroiditis patients and other thyroiditis patients.Methods The patients who were preliminary diagnosed as having higher level of serum thyroid hormone were divided into Graves' disease group,subacute thyroiditis group and painless thyroiditis group.Then all the patients were divided into another two groups according to the level of autoantibody.The value of serumal thyroid hormone and serumal iodine and urinary iodine were measured and the relationship between the groups and the value were observed.Results There was close relationship between serum T 3,T 4,urinary iodine and the types of thyrotoxicosis.Conclusion The morbidity of painless thyroiditis is not uncommon.Clinical situation,serumal iodine,urinary iodine and serumal thyroid hormone may be useful for clinical diagnosis and differential diagnosis of painless thyroiditis.

Asaprimarilyused plasticizerin polyvinyl chloride,d(i2-ethylhexy)lphthalate(DEHP)is extensively used in consumer products,flooring and wall coverings,food contact applications,and medical devices.Because DEHP has been detected in waters,soils and air,and its metabolites have also been detected in human urinary,sufficient evidences show that DEHP is ubiquitous in the environment worldwide.DEHP is already in the blacklist of priority pollutants in water in China.Many researches indicate that DEHP is one kind of endocrine disrupting chemicals in animals,with carcinogenicity,teratogenicity and mutagenicity.Based on the researches and review on DEHP,this paper principally discussed the environmental level,metabolism and biological markers of DEHP,as well as the research progress on human health effects.

Interim Measures for Hospital Review points out that social evaluation is one of the important contents of hospital periodicity evaluation.Through the literature review and analysis,the definitions of hospital social evaluation are examined,and the agents,subjects and contents involved in basic organization structure of hospital social evaluation are analyzed.The theoretical findings can be used to help to eStablish hospital social evaluation system.

The development trend of medical education is comprehensive, which is character-ized by breaking the boundaries among different disciplines, constructing a main line centering on or-gan and system, and implementing student-centered problem-based learning. This paper analyzed the main problems of basic medical education in Wuhan University of Science and Technology, such as insufficient teaching reform to promoting students' autonomous learning and failed to create excellent teaching and research group et al. Also, the paper proposed comprehensive reform measures such as integrating teaching units , establishing Teacher Education Development Center, implementingCourse director andTeam leader system, promoting teaching model ofstudent centered and in-tegrating curriculums of basic medicine to establish course model centering on the organ and system et al, with some success.

Objective To evaluate the effect s of Ginkgo Leaf Extract and diphyridamole injection on patient s with CKD.Methods 60 patients with CKD were made up with 36 cases in Ⅲ phase and 24 cases in Ⅳ phase.The patients with CKD were given Ginkgo Leaf Extract and diphyridamole injection,20 mL/d,for 15 days.The parameters of clini- cal condition,function of kidney,ALB and blood fat were observed before and after the therapy and the data were ana- lyzed.Results There were 28 cases that clinical condition was better; 24cases no difference; and 8 cases worse.The level of TC and TG were significantly decreased after the therapy,as well as the uric protein quality of 24 hours(P0.05). Conclusion Essential treatment for CKD combined with Ginkgo Leaf Extract and diphyridamole injection can improve nutrition,delay the process of CKD and protect the renal function in patient s with Ⅲ phase.
