Type 1 diabetes mellitus(T1DM), which is an autoimmune disease, mostly affect people with hereditary susceptibility under the joint participation of environmental factors.It is known to coexist with other autoimmune disorders such as celiac disease(CD). The prevalence of CD is higher in patients with type 1 diabetes compared with the general population.Most patients affected with both T1DM and CD are atypical for CD at diagnosis, and may be misdiagnosed and subsequently suffered from the delayed treatment.These patients are more likely to develop symptomatic hypoglycemia, or poor blood glucose control, leading to an increased risk of chronic complications and seriously affecting the quality of their life.Thus, screening for CD is recommended in patients with T1DM.Anti-tissue transglutaminase antibody is the preferred biomarker for CD screening in children and adolescents over 2 years of age, with a sensitivity of 95% to 100% and a specificity of 94% to 100%.And a low-carbohydrate diet is often combined with a gluten-free diet.

Objective To clarify the clinical significance of visit-to-visit variability in blood pressure (BP) of stage 3-4 chronic kidney disease (CKD) patients with hypertension.Methods One hundred and fifty-two cases of stage 3-4 CKD patients with hypertension were enrolled in the study.Variability in BP was defined as the standard deviation (SD) in BP.For each patient,SD and mean BP from BP measurements were calculated at all the visits.Correlations between the decline in estimated glomerular filtration rate (eGFR) and SD in BP were analyzed by multivariable regression.Results Visit-to-visit variability in BP was significantly associated with renal function decline (P ＜ 0.05),in addition,baseline eGFR,baseline albuminuria and mean SBP during follow-up were significantly associated with renal function decline as well (all P ＜ 0.05).The percentage of CCBs used in low SD of the SBP group was higher than that in high SD of the SBP (76.1％ vs 58.2％,P ＜ 0.05).Conclusion Visit-to-visit variability in BP is significantly associated with renal function decline.Drugs which can decrease the variability of blood pressure should be the first choice in the treatment of hypertension.

Objective To observed the impact of selenium supplementation therapy on the thyroid perioxidase antibody(TPO-Ab) levels and serum oxidative stress[malondialdehyde(MDA, glutathione peroxidase(GPx), and superoxide dismutase(SOD)] in patients with Hashimoto′s thyroiditis. Methods 79 patients with Hashimoto′s thyroiditis were randomly divided into trial group(n=44) and placebo group(n=35) .The double-blind treatment was for 24 weeks. The thyroid hormone levels, serum TPO-Ab levels, and oxidative stress indexes(MDA, GPx, and SOD) of both groups were detected before and after treatment. Results (1)There was no change of thyroid hormone levels either before or after treatments of both groups(P>0.05). (2)TPO-Ab of the trial group decreased significantly after the treatment(P<0.05). While the placebo group has little change. Group with TPO-Ab≤200 IU/ml and the course≤1 year manifested the most obvious declines by 29.98% and 26.63% respectively. (3)The oxidative stress level of trial group significantly decreased after 24 weeks. There was significantly positive correlation between the oxidative stress indexes and TPO-Ab. However the placebo group was with little change. Conclusion Selenium supplementation may reduce the level of TPO-Ab titers and oxidative stress in patients with Hashimoto′s thyroiditis, especially for those with lower antibody titers and short course.
