Thyroid hormones (TH) play an imp or tant role in the development and maturity of the mammalian brain. Maternal TH de ficiency, even subclinical hypothyroidism, leads to poor neurodevelopment of the fetus. Screening of pregnant women for hypothyroidism is recommended. Identific ation of the TH-responsive genes in the developing brain and investigation on t heir functions are helpful to provide insights into the molecular mechanisms by which TH influence brain development.

Objective To investigate the correlation between the glycosylated hemoglobin (HbA1c) detection data and hemo‐rheological indicators in diabetes patients to provide reference basis for its treatment and prevention .Methods One hundred and forty‐two patients with typeⅡdiabetes mellitus(T2DM ) in the hospital were selected as the research subjects and divided into the A group(69 cases ,better control) and B group(73 cases ,poor control) according to the HbA1c detection results .Contemporaneous 70 healthy individuals undergoing physical examination were selected as the control (C group) .The detection results of HbA1c ,hemo‐rheology and biochemical indexes were performed the contrastive analysis .Results Except hematocrit and erythrocyte deformation index without statistical difference among 3 groups(P>0 .05) ,the other hemorheologic indicators had statistical differences among 3 groups(P<0 .05) .No matter the HbA1c level in T2DM patients ,the hemorheological indexes ,triglyceride and total cholesterol were higher than those in the healthy people ,When the HbA1c leve was poorly controlled ,the increase degresss of various indexes were more significant .Conclusion The abnormality of hemorheology indices exist in most of the patients with diabetes mellitus .It is recommended that clinic should monitor the HbA1c level for long term and strictly observe the change of hemorheology indexes to guide the clinical treatment for reaching the effects of early vascular protection and prevention of diabetic complications .

Thyroid-stimulating hormone receptor(TSHR)is an important autoantigen whose cleavage and shedding can induce autoimmunity.The TSHR is the main functional receptor of the thyroid.The shedding of the ? subunit plays an important role in the forming of TSAb and balancing between TSAb and TBAb.Research on the cleavage and shedding of the TSHR extracellualar domain helps to gain a deep insight into the structure and function of TSHR,illuminate the pathogenesis of autoimmune thyroid disease and find out a new therapy.The structure of TSHR,the mechanism and the significance of its cleavage and shedding are reviewed in this article.

We took such measures in internal medicine practice teaching in five-year program as actualizing special teachers’supervision system,adopting multiple teaching methods (enlightening,case-based,question-based,multimedia),taking interview of teachers and students,and enhancing doctor-patient communication.

Objective To study the effect of hypothyroidism on oxidative stress status in developing rat brain and to further explore the mechanism of impaired brain development caused by hypothyroidism. Methods Perinatal hypothyroidism was induced by administering propylthiouracil(PTU) solution to the dams by gavage.The oxidative stress indexes were measured in brain homogenate of normal and hypothyroid pups which were sacrificed on the 21st d after birth. Results As compared to the control,the following indexes were found to be increased in the hypothyroid group: protein carbonyl contents,thiobarbital acid reactive substances,reduced glutathione,total antioxidative capacity,activities of superoxide dismutase and glutathione peroxidase(P0.05). Conclusion Hypothyroidism during rat brain development may cause oxidative stress,which may be related to the brain damage caused by hypothyroidism.

Objective To explore the effects of oxidative stress in porcine iliac endothelial cells(PIECs) induced by high glucose. Methods After being intervened by high glucose for some time, dihydroethidium (DHE) or dihydrorhodamine 123 (DHR123) was used as a reactive oxygen species(ROS) capture. The mean fluorescent intensity(MFI) of above probes which were the products of intracellular oxidation was detected by fluorescent microscopy and flow cytometry, and the level of ROS was thus measured. With lucigenin as chemiluminescence agent, luminescence changes were detected by chemiluminescence analyzer after addition of NADPH to observe the effect of high glucose on activity of NADPH oxidase(NOX). Results Intracellular MFI was markedly elevated with the concentration of high glucose and time of exposure to high glucose. It was revealed by flow cytometry that the NOX activity was significantly activated compared with normal medium treated PIECs(P

Objective: To modify the mono-antigen DNA vaccine of Mycobacterium tuberculosis with ubiqutin, so as to obtain more potent immune response. Methods: We constructed Mycobacterium tuberculosis MPT64 antigen DNA vaccine (pM) and ubiquitin-MPT64 fusion gene DNA vaccine (pUM). The constructed DNA vaccines were intramuscularly inoculated into female BALB/c mice separately. The serum antibodies(including IgG, IgG1,and IgG2a), cytokines (IFN-γ, IL-4) and cytotoxic T lymphocyte(CTL) response were determined in immunized mice. Results: The IgG level in the pM group was higher than that in the pUM group(P<0.01) and the ratio of IgG2a/IgG1 in the pM group was lower than that in the pUM group([2.16±0.3] vs [4.48±0.4],P<0.05). The IFN-γ level was higher (P<0.01) and the IL-4 level was lower (P<0.01) in the pUM group than those in the pM group. Furthermore, the pUM group had higher CTL activity than the pM group. It was indicated that the fusion gene DNA vaccine induced weaker humoral immune response but stronger cellular immune response compared to single gene DNA vaccine. Conclusion: The fusion gene DNA vaccine constructed in the present study might be more effective for prevention against tuberculosis than the single gene DNA vaccine.
