Objective To observe the effect of iodine deficiency and hypothyroidism on the protein expressions of CREB in the entorhinal cortex of pups.Methods Twenty-eight female Wistar clean rats after pregnancy were randomly divided into control group,hypothyroid 1,2 group and iodine deficient group(7 in each group).From GD6 till PN28,iodine-deficient group was administered with iodine-deficient diet [iodine content:(14.11 ?1.96) ng/g] and tap water;hypothyroid 1 and 2 group were administered with 5 mg/L and 15 mg/L PTU in the drinking water and fed with normal diet [iodine content:(470.50?46.52) ng/g].Control group received tap water and normal diet during the experiment.Five pups from each group were sacrificed and intracardiac perfused at PN7,PN14,PN21,PN28 and PN42.Brains were removed,fixed and sectioned coronally.All sections were observed and were analyzed for the protein expression of CREB by immunohistochemistry in the entorhinal cortex.Results At PN7,there was no significant difference in the expression of Ng in all four groups.At PN14 and PN21,the expression of CREB in the entorhinal cortex in hypothyroid 1,2 group and iodine deficient group were significantly lower than those of controls(P

0.05).Histopathological examination showed no pathological change in the brain,liver,kidneys,and spleen of the mice,but reduced spermatogenic cells spermatozoa.The sperm motility was(40.58?7.75)% in the control,(7.40?1.06)% in the experiment group 1(q=16.909,P0.05).No significant difference in the sperm densities was found among the groups.Conclusions Intermediated alternating magnetic field has adverse effects on the reproduction of mice.Testosterone is one of the target organs of electromagnetic radiation.It is sensitive to IF magnetic field(40 kHz,28 mT).Blood,brain,liver,kidney and spleen of mice are not effected by IF alternating magnetic field.

Objective To investigate the clinical significance of irregular antibody screening positive patients in the blood transfusion.Methods From September 2003 to September 2012,5 260 samples of blood test were given pre-transfusion irregular antibody detection,and the patients with positive antibody screening were statistically analyzed.Results Of 5 260 samples,38 cases (6.8％) had irregular antibodies,the difference between males and females was statistically significant(x2 =2.646,P ＜ 0.05).The Rh blood group had the highest proportion in irregular antibodies;pregnancy history and history of blood transfusion group,pregnancy history group,history of blood transfusion group were significantly higher than those without history of pregnancy and transfusion history groups,the difference was statistically significant (x2 =28.827,P ＜ 0.05).Conclusion Screening of irregular antibodies plays an important role in the safety of clinical blood transfusion.

Retinitis pigmentosa (RP) is a hereditary disease characterized by the progressive loss of photoreceptor cells. Disease pathology primarily affects rod photoreceptor cells first but light-insensitive cone photoreceptor bodies can survivor longer. Delivered by adeno-associated viral vector or lentiviral vector, expression of microbial-type rhodopsin, channelrhodopsin-2 or archaebacterial halorhodopsin in the survived retinal cells can substitute for the native phototransduction cascade in mouse models of retinitis pigmentosa. It can also restore light sensitivity and activate all retinal cone pathways and drive sophisticated retinal circuit functions. Thus, expression of channelrhodopsins or halorhodopsin might be a potential strategy for the restoration vision of patients with RP.

Objective To study the protective effect of hyperoxic liquid preconditioning in myocardial ischemia-reperfusion injury. Methods Thirty rabbits were randomly divided into three groups: group A undergoing all procedures except ischemia-reperfusion, group C receiving the routine infusion of hyperoxic liquid 15mL/kg for seven days, and group B receiving the routine treatment infusion of saline instead of hyperoxic liquid 15mL/kg. Seven days later, the myocardial ischemic reperfusion model (I/R) was fabricated, ECG and homodynamic index were monitored simultaneously. Plasma MDA and SOD level was assayed before ligation, 30min after ligation and 1, 2, 3h after reperfusion. Results Hyperoxic liquid preconditioning can lower ST segment and improve index of hemodynamics and significantly reduce myocardial infarction size in group C compared with group B((P

Objective: To investigate the effect of adhesion of Lactobacillus reuteri JCM1081 to enterocyte-like HT-29 cells on filamentous cytoskeleton.Methods:Cultured human intestinal enterocyte-like HT-29 cells were used.Cell permeability was examined in vitro by Evans blue labeled albumin and Examination of F-actin was conducted by direct immuno-fluorescence labeling using fluorescein labeled phalloidin.Results:Lactobacillus reuteri JCM1081 did not alter cell integrity and prevented the increase in permeability induced by enteropathogenic Escherichia coli infection.The distribution of F-actin were also not altered.Conclusion :Lactobacillus reuteri JCM1081 exerts a protective effect against the filamentous cytoskeleton rearrangement and permeability lesions promoted by enteropathogenic Escherichia coli infection.
