Objective To explore the clinical characters,therapy and prognoses of hyperthyroid cardiac disease in children.Method Fourteen hospitalized cases with hyperthyroid cardiac disease(5-14 years old) collected from January 2001 to January 2005 were analyzed(retrospecti)vely.Results Fourteen children with hyperthyroid cardiac disease had different degree of enlarged of heart,arrhythmia and heart failure.All of the cases were received treatment of hyperthyroidism and anti-arrhythmia.After admission for 2 weeks,the symptoms of 13 cases relived or disappeared,and after 4-6 weeks the enlarged heart,arrhythmia and heart failure disappeared.One case died after recurrent heart failure.Conclusions Hyperthyroid cardiac disease in children can be curative and the changes of cardiac blood-vessel can be recuperative.It is critical for doctors to know the manifestations of hyperthyroidism and take the cardiac examination and the function of the thyroidism and take proper treatment as soon as possible.

At the beginning of the 1980s, a concept of viable but non-culturable(VBNC) was suggested. VBNC is a survival strategy adopted by microorganisms when they are exposed to environmental stress. This article try to make a summary of research of the conditions of VBNC formation, recovery of culturability and methods of VBNC cells detection. In addition, introduces the first growth factor of microorganisms-Rpf.

0.05).Conclusions IL-11 unlikely to stimulate the growth of the CEM leukemia cell.And did not affect the antitumor effect of HD-MTX.It can be used as an assisting drug in program of acute lymphoblastic leukemia(ALL) therapy.

While the number of the enrolled postgraduate students is continuously increased and the various reforms go in depth, there appear some new problems and contradictions in the education of doctorial students.Among those problems,the lack of the doctorial student resource,especially the lack of the excellent doctorial student resource,is the most prominent problem that re- stricts the progress of the doctorial student education.In order to solve these problems,this article analyzes the factors influencing the resource of the students and put forward the strategy to deal with these factors.

Objective:To investigate the existence of side population cells with the potency of stem cells in human gallbladder carcinoma cell line GBC-SD and the differences in ABCG2,Oct-4 and CD34 expression among SP cells,non-SP cells and GBC-SD cells.Methods:SP and non-SP cells were sorted from GBC-SD cells by fluorescence-activated cell sorting(FACS).The expression of ABCG2,Oct-4 and CD34 in SP cells,non-SP cells,and GBC-SD cells was detected by reverse transcription-polymerase chain reaction(RT-PCR),Western blot,flow cytometry(FCM)and immunofluorescence chemistry.Results:SP cells with stem cell potency were isolated from GBC-SD cells with a proportion of(0.64±0.08)%.The metastatic ability of SP cells was obviously higher than that of non-SP cells and GBC-SD cells(P<0.05).The expression of ABCG2 was significantly higher in SP cells than in non-SP cells and GBC-SD cells[(89.56±3.86)%vs.(1.32±0.49)%and(12.37±1.61)%,P=0.001].The expression of Oct-4 in these cells was(94.87±1.40)%,(88.16±2.34)%and(90.17±1.61)%,respectively(P>0.05).CD34 was neady absent in these cells on protein level[(1.78±0.51)%vs.(0.63±0.21)%and(0.96±0.381)%,P>0.05)],but it was highly expressed in non-SP cells and GBC-SD cells and absent in SP cells off mRNA leve;.Conclusion:SP calls which hava the potency of stem cells,exist in human gallbladder carcinoma GBC-SD cell line and have the phenotype of ABCG2+Oct-4+CD34-.

Objective To analyze the MRI characteristics of cavernous angioma of the epidural space in spine.Methods MR imaging features of cavernous angioma of epidural space in 3 cases confirmed by surgery-pathology were analysed with literature review . Results Among the three cases,the tumors located in the lumbar spine in one and in the thoracic spine in 2.The tumors were all at posterior to the spinal cord and shuttle-shaped,the major axis was consistent with the spinal ordinate axis,the corresponding plane spinal cords were compressed and resulting in distortion and shift.The tumors were high signal intensity on T_2WI,and obviously homogeneous enhanced after Gd-DTPA administration. Conclusion MRI examination is the best method to diagnose this kind of disease.

Objective To analyze the clinical data of patients with Cushing's syndrome(CS)and to un-derstand the relationship between glucose metabolism and CS .Methods Oral glucose tolerance test (OGTT), the level of insulin, body mass index(BMI), 24-hour urinary free cortisol(24h UFC), family history of diabetes in patients with CS were retrospectively analyzed .Results The course of disease in patients of CS complicated with diabetes mellitus ( CS/DM) group was longer than CS complicated with impaired glucose tolerance ( CS/IGT) and CS complicated with normal glucose tolerance (CS/NGT)group.66.67%of patients with CS/NGT have insu-lin resistance .Logistic regression analysis indicated that age , course of disease , midnight plasma cortisol were risk factors of CS induced diabetes mellitus .CS/DM group had higher proportion of family history of diabetes . 24h UFC and BMI had no significant differences among the three groups (P>0.05).Conclusions Age, course of disease , midnight plasma cortisol are risk factors of CS induced diabetes mellitus .OGTT and insulin level de-termination are necessary for diagnosis and intervention treatment at the early stage .

Objective To compare the cardiac function parameters in gated SPECT determined by filtered back projection (FBP) and OSEM reconstruction methods. Methods One hundred and forty-four patients underwent 99Tcm-MIBI gated-SPECT imaging studies. The parameters LVEF, EDV and ESV, were derived using quantitative gated SPECT (QGS), four-dimensional model SPECT (4D-MSPECT) and emory cardiac toolbox (ECToolbox) softwares. Each image was reconstructed by FBP or OSEM. Bland-Altman analysis and paired t-test were applied to evaluate those parameters. Results Correlation coefficients for LVEF, EDV and ESV between FBP and OSEM methods were all more than 0.93 (all P<0.001). EDV calculated by FBP was lower than that by OSEM using QGS software, but became the opposite when using 4D-MSPECT and ECToolbox softwares. (QGS: (82.2±39.1) ml vs (83.5±40.8) ml, t=-2.53, P<0.05; 4D-MSPECT: (93.5±46.9) ml vs (88.8±45.2) ml, t=5.95, P<0.01; ECToolbox: (106.4±51.1) ml vs (100.8±49.0) ml, t=3.99, P<0.01). ESV calculated by FBP was higher than that by OSEM using 4D-MSPECT software (4D-MSPECT:(37.5±41.4) ml vs (34.8±37.6) ml, t=3.92, P<0.01). LVEF calculated by FBP was lower than that by OSEM using QGS software ((62.1±16.9)% vs (63.1±16.1)%, t=-3.14, P<0.05), but higher than that by OSEM using ECToolbox software ((74.1±18.8)% vs (71.3±17.1)%, t=5.28, P<0.01). Conclusion Generally, cardiac functional parameters based on FBP and OSEM construction methods correlated well, although they might have singnificantly different results.
