ABSTRACT
Clinical and laboratory data of 5 cases of fulmiant type 1 diabetes mellitus (FTlDM) hospitalized in our department of endocrinology and metabolism from February 2014 to December 2016 were collected analyzed.All these patients characterized by acute onset and severe ketoacidosis,with course of 1-3 d.At admission,the blood glucose level was 31.8 ～ 58.9 mmol/L,HbA1c 6.0％ ～ 7.5％,F-CP 0.01～0.05 nmol/L and 2 hC-P 0.02～0.05 nmol/L The pancreatic βcell function had no significant improvement after 1year.FTlDM patients have clinical features of abrupt onset,often with severe metabolic disorders,poor prognosis and seriously damaged islet β cell function.
ABSTRACT
Objective To investigate the relationship between leptin level of IGR patients and intima-media thickness (IMT) of carotid arterial. Methods One hundred and eighteen IGR patents were enrolled into the following three groups according to the result of oral glucose tolerance test (OGTT): 38 cases of the purely impaired fasting glucose (IFG) group, 42 cases of the purely impaired glucose tolerance (IGT) group and 42 cases of the IFG combining with IGT (IFG + IGT) group. Thirty-eight cases with normol glucose tolerance (NGR) were enrolled in the NGR group. The blood fat, fasting blood-glucose (FBG), fasting insulin (insulin), fasting C peptide , 2 h-postprandial blood glucose , 2 h-insulin , 2 h-C peptide , glycosylated hemoglobin (HbA1C), C-reactive protein (CRP), body mass index (BMI), leptin and IMT were determined in patients of the three groups and the healthy controls. The multiple linear regression was used to analyze the relationship between leptin level and IMT , and person correlation was further used to analyze the affinity degree between leptin level and IMT. Results Compared with the NGT group, the inter-group comparison showed that leptin level was significantly increased in the IFG, IGT and (IFG + IGT) groups (P < 0.05, respectively). Compared with the IFG and IGT groups, IMT and the leptin level were increased in the (IFG + IGT) group (P < 0.05, respectively). The multiple linear regression analysis showed that leptin level was correlated with the increase of IMT in the (IFG + IGT) group (P < 0.05), but not in the IFT group and the IGT group. Conclusion The leptin level in the IGR group and the IMT in the IFG + IGT ) group were significantly increased , the leptin level was closely associated with IMT.
ABSTRACT
Objective To discuss the correlation between C-peptide level and autonomic neuropathy in diabetic foot in patients with type 2 diabetes mellitus (T2DM). Methods The levels of fasting blood glucose (FBG), 2 h postprandial blood glucose (2 h-PG) and fasting C-peptide (FC-P) were detected in 124 T2DM patients. The Neuropad was used to test functions of sudomotor nerves in foot. Patients were divided into two groups:diabetic autonomic neuropathy (DAN) group and non-autonomic neuropathy group (NDAN) according to the results of functions of sudomotor nerves in foot. Values of gender, age, body mass index (BMI), blood pressure, FBG, 2 h-PG and FC-P were compared between the two groups. The Pearson correlation analysis was carried out between the indexes mentioned above and the time for completing color change of Neuro-pad. Results There were no significant differences in gender, age, FBG and 2 h-PG between two groups (P>0.05). The FC-P level was (1.07 ± 0.75)nmol/L in DAN group, which was significantly lower than that in NDAN group (1.43 ± 1.00) nmol/L (P > 0.05). The time for completing color change of Neuropad was negatively correlated with C-peptide. Conclu-sion The autonomic nerve functions in diabetic foot is closely related with C-peptide. It is inferred that C-peptide may have protective effect on autonomic nerves in diabetic foot.
ABSTRACT
<p><b>OBJECTIVE</b>To assess the value of echo-tracking technology in evaluating endothelial function of the femoral artery in patients with Grave's disease.</p><p><b>METHODS</b>Thirty-four patients with Grave's disease patients and 30 normal adults as controls were recruited in this study. The intima-media thickness (IMT), arterial stiffness (β), pressure strain elastic modulus (Ep), arterial compliance (AC), pulse wave conducting velocity (PWVβ) and augmentation index (AI) parameters were examined using echo-tracking technology for evaluating the right femoral arterial elasticity.</p><p><b>RESULTS</b>Compared with the control subjects, the patients with Grave's disease showed significantly increased β, Ep, and PWVβ and significantly decreased AC (P<0.05), but the argumentation index were similar between the two groups (P>0.05). In patients with Grave's disease, β and Ep were positively correlated with FT3, FT4, TT3, TT4, and PWVβ was positively correlated with FT3 and FT4.</p><p><b>CONCLUSIONS</b>Echo-tracking technology can provide more accurate quantitative evidences for early diagnosis of femoral artery endothelial dysfunction in patients with Grave's disease, but the influence of procedural factors on the measurement accuracy should be considered in the evaluation.</p>

Objective To analyze the relationship of the expression level of estrogen receptor (ER), progesterone receptor (PR) and human epidermal growth factor receptor-2 (HER-2, c-erbB-2) of breast invasive ductal carcinoma (IDC) with ultrasonographic characteristics. Methods Totally 104 patients with IDCs confirmed pathologically were involved in this study. ER, PR and c-erbB-2 expression in the IDC specimens was determined by immunohistochemical staining technique. The correlation between the ultrasonographic features and the positive expression of ER, PR or c-erbB-2 was analyzed. Results The positive expression rate of ER and PR in the group with tumor spiculation sign and posterior acoustic attenuation was higher than that in the group without. The positive expression rate of ER differed significantly (P<0.05) while that of PR did not (P>0.05). The over-expression rate of c-erbB-2 in the group of microcalcification, sufficient blood flow and axillary lymph node metastasis was higher than that in the group of non-microcalcification, deficient blood flow or without axillary lymph node metastasis (P<0.05). The expression of ER, PR and c-erbB-2 was not related to the size of tumor (P>0.05). Conclusion The expression of ER and c-erbB-2 is closely related to the ultrasonographic characteristics of IDC, which may, to some extent, reflect the expression level of ER and c-erbB-2.
