ABSTRACT
Objective To study the effect of high-dose methylprednisolone intravenous pulse therapy on immunoglobulins and CD series in patients with active moderate-to-severe Graves' orbitopathy. Methods Twenty-seven patients with active moderate-to-severe Graves' orbitopathy were enrolled in this study. All the patients received iv methylprednisolone pulse therapy for 12 weeks according to the 2016 European Thyroid Association/European Group on Graves'Orbitopathy(EUGOGO) Guidelines. Serum thyroidal autoantibodies, such as thyroid-stimulating hormone receptor antibody ( TRAb) , anti-thyroperoxidase antibody ( TPOAb) , and serum immunoglobulins, such as IgG, IgE, IgA, IgM were evaluated at the baseline, at the end of 4th and 12th week. Percentages of CD3+ T cells, CD4+ T cells, CD8+T cells and CD19+ B cells, CD16+ or CD56+ NK cells were also evaluated at each time point. Results TRAb, TPOA and IgE, IgG, IgA were significantly decreased both after 4th week and after 12th week (all P<0.05). Percentages of CD3+ T cells, CD4+ T cells and CD4+/CD8+ ratio were gradually decreased after treatment. However, change of CD8+T cells was not significant (P>0.05). Conclusion High-dose methylprednisolone may exert an immunosuppressive effect not only by modifying humoral and cellular immune functions, but also by decreasing serum immunoglobulins.
ABSTRACT
Objective@#To investigate the use of diabetes medications and their effects on the community diabetic patients in Shanghai, China, and provide the evidence for the use of antidiabetic drugs in diabetic patients in the region.@*Methods@#The data were from a database of a 2018 Survey on Community Diabetes Mellitus in Shanghai, China. There were 4 612 subjects included in this cross-sectional study in 2018. According to the use of antidiabetic drugs, the population was divided into untreated group, single drug group, double drugs combination group and multi-drugs combination group, to compare the fasting blood glucose, glycosylated hemoglobin, BMI and prevalence of diabetic complications in different groups.@*Results@#About 70.9% of the 4 612 patients used hypoglycemic agents, 34.8% used metformin, 35.1% used sulfonylureas, 22.9% used alpha glycosidase inhibitors, and 13.8% used insulin. The prevalence of diabetic nephropathy, retinopathy, neuropathy, stroke, and diabetic foot was higher in the combination than in the untreated and single-drug users (P<0.01). Only 41.3% subjects had HbA1C<7%. The fasting blood glucose and HbA1C values were lower in the untreated group than in other three medication groups, and the rate of the HbA1C reaching target in the untreated group was higher than the other medication groups (P<0.01). As the types of drug increased, HbA1C was less likely to reach the target (P<0.01). There were 42.2% of patients with BMI<24 kg/m2, and there was no significant difference in the proportion of BMI reaching target among the four groups (P>0.05).@*Conclusion@#The most common used antidiabetic drugs in diabetic patients in Shanghai are metformin, sulfonylureas, α-glycosides inbibitor, and insulin. The blood glucose control in diabetic patients in Shanghai community is not good enough. Patients with a longer duration of diabetes, a lower rate of HbA1C at goal, and a higher prevalence of diabetic complications may be more prone to use multiple hypoglycemic drugs.

ABSTRACT
Objective@#To reclarify the natural change trend of several hormones with age in Chinese population.@*Methods@#A cross-sectional survey was performed including 5 935 healthy individuals (2 286 males and 3 649 females) in the final statistical analysis. All participants received questionnaire survey, anthropometric index and laboratory tests including sex-related hormones, insulin, thyroid hormones, and 25-hydroxyvitamin D [25(OH)D]. Kruskal-Wallis test or One-way ANOVA analysis was used to compare hormone levels in different age groups. Spearman analysis was used to explore the correlation between age and hormone levels.@*Results@#(1) Follicle stimulating hormone (FSH) and luteinizing hormone (LH) concentrations increased with age from 40 years in both males and females, and stabilized at high levels after the age of 60 in females and 80 in males. Estradiol level in females started to decrease since 40 years old, then stabilized around 70 years. Sex hormone binding globulin level increased significantly with age in males, but decreased in postmenopausal females. (2) Fasting serum insulin gradually decreased with age in males until 60 years, but without obvious change in females. Fasting plasma glucose and HbA1C increased with age in both males and females. (3) Thyroid stimulating hormone (TSH) increased slowly with age in both males and females. (4) 25(OH)D increased with age in both males and females overall, especially more obvious in males. (5) During 41-60 years, FSH and LH levels in menopausal females were much higher than those in premenopausal females, while estradiol level in menopausal females was much lower. Compared with premenopausal females aged 41-50 years, estradiol level in premenopausal females was much lower in 51-60 years.@*Conclusion@#The levels of several important hormones are related with age, revealing a natural change trend as aging in Chinese population.

ABSTRACT
<p><b>BACKGROUND</b>The glucose fluxes of individuals with prediabetes in Chinese population are not clear. This study was to determine whether the endogenous glucose production (EGP), oral glucose rate of appearance (Ra) and glucose rate of disappearance (Rd) were different in Chinese individuals with prediabetes under fasting conditions and following an oral glucose challenge.</p><p><b>METHODS</b>Five subjects with type 2 diabetes, 5 subjects with prediabetes and 5 non-diabetic subjects matched for age, weight, fat free mass and body mass index underwent a 180 minute stable glucose isotope tracing ([6, 6-(2)H2] glucose, [1-(13)C] glucose, and [U-(13)C] glucose) study under fasting and after ingestion of a 75 g oral glucose load. Isotope glucose enrichment was measured by gas chromatography-mass spectrometry. Insulin sensitivity was estimated using the oral glucose tolerance test (OGTT)-derived insulin sensitivity index, β cell function was determined by the insulinogenic index (δI30/δG30).</p><p><b>RESULTS</b>The insulin sensitivity index (P = 0.043) and insulinogenic index (P = 0.021) were decreased in subjects with prediabetes compared with non-diabetes. Fasting EGP was slightly higher (P = 0.29) and postprandial EGP was comparable in subjects with prediabetes and non-diabetes during 120 minutes after glucose ingestion, but nadir EGP occurred later in prediabetic than non-diabetic subjects. Ra did not differ among the three groups. Rd was substantially lower in subjects with prediabetes than non-diabetes after glucose intake (P = 0.013).</p><p><b>CONCLUSION</b>The mild hyperglycemia observed among individuals with prediabetes may result from decreased Rd during the postprandial state.</p>
