Objective: To study the effect of levothyroxine replacement therapy on improving diffused left ventricular myocardial lesions and cardiac function in patients with hypothyroidism. Methods: Our research included 2 groups: Hypothyroidism group,n=20 newly diagnosed patients and Control group, n=17 normal healthy subjects. Diffused left ventricular myocardial lesions were quantitatively evaluated by non-invasive cardiac MRI T1 mapping technique. Left ventricular myocardial T1 value and left ventricular function before and after levothyroxine replacement therapy were compared; the relationship between T1 value and thyroid function and the relationship between T1 value and the indicators of left ventricular function were analyzed. Results:①Compared with Control group, Hypothyroidism group had increased left ventricular myocardial T1 value, P<0.01, while decreased cardiac index (CI) and left ventricular peak filling rate (PFR), allP<0.05.②In patients with hypothyroidism, left ventricular myocardial T1 value was negatively related to serum FT3 level (r=-0.52,P=0.0006) and PFR (r=-0.43,P=0.0085).③Compared with pre-therapeutic condition, the patients with recovered normal thyroid function showed obviously decreased left ventricular myocardial T1 value and improved CI, PFR. Conclusion: Levothyroxine replacement therapy may improve diffused left ventricular myocardial lesions in patients with hypothyroidism, and therefore improve the cardiac function.

Objective:To examine factors that may have impact on the Mini-Mental State Examination ( MMSE) screening validity, which could lead to further establishing the general model of the MMSE score in Chinese health elderly and to improve the screening accuracy of the existing MMSE reference. Methods:Based on the data of the Chinese Longitudinal Healthy Longevity Survey ( CLHLS ) , the MMSE scores of 19 117 normal elderly and 137 dementia patients who met the inclusion criteria were used for the analysis. The area under the curve ( AUC) and validity indexes were used to compare the screening accuracy of various criteria. Multiple linear regression was used to identify factors that had impact on the MMSE score for both the normal and dementia elderly. Descriptive analysis was performed for differences in the MMSE scores by age trends and gender between the normal and dementia elderly. Results:The AUC of MMSE was≥0 . 75 ( P<0 . 05 ) . The MMSE score of the normal elderly declined nonlinearly as the age grew older(male:R2 =0. 924, P<0. 05; female: R2 =0. 951, P<0. 05), and increased nonlinearly as the education level rose(male: R2 =0. 948, P <0. 05; female: R2 =0. 859, P<0. 05). The females had significantly lower MMSE scores than the males, with a faster decline trend with age than the males (95%CI of female partial regression coefficient was not overlapped with 95%CI of male partial regression coefficient) . The dementia elderly showed a much lower MMSE score ( male:difference of Z score:-1 . 573 , P<0 . 05;female:difference of Z score:-1 . 222 , P<0 . 05 ) and ten-ded to with a faster decline speed than that of the normal elderly (95%CI of dementia partial regression coefficient included 95%CI of normal partial regression coefficient) . Conclusion:The screening validity of MMSE in CLHLS is not affected by educational level. The analysis of factors that may impact on the MMSE screening validity are gender, age, vision and residence which with validity identification. These four fac-tors can be used as assist tool of MMSE in the screening of dementia to improve the screening accuracy.

Objective To evaluate the effects of ischemic postconditioning on brain injury induced by myocardial ischemia-reperfusion (I/R) in diabetic rats.Methods Diabetes mellitus was induced by intraperitoneal streptozotocin 60 mg/kg and confirmed by blood glucose level ＞ 16.7 mmol/L.Thirty male Sprague-Dawley rats,weighing 220-280 g,in which diabetes mellitus was successfully induced,were randomly allocated into 3 groups (n =10 each) using a random number table:group sham operation (group S),group I/R and group ischemic postconditioning (group P).Myocardial I/R was induced by occlusion of the anterior descending branch of the left coronary artery in I/R and P groups.Group P received 3 cycles of 10 s reperfusion followed by 10 s ischemia at the end of myocardial ischemia.The rats were sacrificed at 120 min of reperfusion and the brains were removed for microscopic examination and for determination of cell apoptosis (by TUNEL) and expression of interleukin-6 (IL-6),IL-8,IL-10,glycogen synthase kinase-3 beta (GSK-3β) and phosphorylated GSK-3β (pGSK-3β) (by immuno-histochemistry).Apoptotic index was calculated.Results Compared with group S,apoptotic index was significantly increased,IL-6 and IL-8 expression was up-regulated,and IL-10 and pGSK-3β expression was downregulated in I/R and P groups (P ＜ 0.01).Compared with group I/R,apoptotic index was significantly decreased,IL-6 and IL-8 expression was down-regulated,and IL-10 and pGSK-3β expression was up-regulated in group P (P＜0.01).There was no significant difference in GSK-3β expression among the 3 groups (P ＞ 0.05).The pathologic changes were significantly attenuated in group P as compared with group I/R.Conclusion Ischemic postconditioning can attenuate brain injury induced by myocardial I/R in diabetic rats,and inhition of activity of GSK-3β may be involved in the mechanism.
