Objective@#To determine the change of gene expressions in human perirenal adipose tissue (PAT) and oblique abdomen subcutaneous adipose tissue (SAT) of overweight and obese subjects.@*Methods@#Ninety-seven patients, including 35 overweight/obese patients and 62 non-obese patients, who underwent renal surgery were included. The clinical data and various gene expressions in PAT and SAT of two groups were analyzed.@*Results@#Body mass index, waist circumference, systolic blood pressure, resting heart rate, fasting blood glucose, and serum creatinine were significantly higher in overweight/obese patients than those in non-obese patients(P<0.05 or P<0.01). Compared with non-obese patients, PAT adipocytes showed bigger, and the expressions of uncoupling protein-1 (UCP1) mRNA and protein were markedly lower in overweight/obese patients. The mRNA expressions of CIDEA and adiponectin in PAT of overweight/obese patients were significantly lower, while leptin, monocyte chemotactic protein 1, interleukin (IL)-6, and IL-10 mRNA expressions were significantly higher. There were no significant differences in the related gene expressions of SAT between the two groups.@*Conclusions@#Different parts of adipose tissue reveal various characteristics, and play different roles in the occurrence and development of obesity. UCP1 expression is decreased in PAT of overweight/obese patients, with the changes of adipocytokine expressions. (Chin J Endocrinol Metab, 2018, 34: 567-572)

Objective To evaluate the association between preoperative serum thyroglobulin concentration and aggressive behavior of papillary thyroid cancer(PTC).Methods A total of 334 PTC patients diagnosed by surgical pathology treated in our hospital from Jan.2013 to Dec.2017 were retrospectively reviewed.Patients were divided into two groups according to Tg levels and clinicopathological characteristics between the two groups were compared.Binary logistic regression analysis was conducted to evaluate the factors influencing extrathyroidal extension and lymph node metastasis of PTC.Results High level of preoperative serum Tg was signifcantly associated with old age,multifocality,larger maximum tumor size,more frequent extrathyroidal extension,lymph node metastasis,and advanced T and TNM stage(P＜0.05).Maximum tumor diameter ＞2 cm(P=0.031) and preoperative serum Tg level ＞17.21 ng/ml(P=0.028) were independent risk factors for extrathyroidal extension.Maximum tumor diameter ＞2 cm(P=0.007) and preoperative serum Tg levels ＞25.40 ng/ml (P=0.016) were independent risk factors for lymph node metastasis,whereas female was a significant protective predictive factor(P＜0.001).Conclusion Preoperative serum Tg levels may serve as an independent risk marker for extrathyroidal extension and lymph node metastasis of PTC,and partly contributes to predict aggressive behavior of PTC.

[Summary] The relationship between the state of cognition and hypertension in 155 type 2 diabetic patients was studied.The results showed that significant difference in the state of cognition was found in patients with or without hypertension,so as to those with poorly or well controlled hypertension (P＜0.05).Systolic blood pressure,pulse pressure,mean arterial blood pressure,and duration of hypertension were negatively correlated with multiple cognitive domains,suggesting that proper control of blood pressure may have a protective effect on cognitive function in type 2 diabetic patients.

The clinical data of patients with hypoparathyroidism accompanied by elevated and normal muscle enzymes were analyzed retrospectively.The results showed that there were no differences in age,gender,pathogenesis,etiology,and parathormone level between groups with elevated muscle enzyme and normal muscle enzyme.Serum calcium concentration in the group with normal muscle enzyme was within normal range.Serum calcium concentration in the group with elevated muscle enzyme was significantly lower than that in the group with normal muscle enzyme (P＜0.01).As the serum calcium concentration rose,the elevated enzyme level gradually returned to normal range,suggesting that the decrease of serum calcium concentration resulted in the elevated muscle enzyme levels in patients with hypoparathyroidism.

Objective To explore the relation between glucose fluctuation state and diabetic chronic compli-cations in type 2 diabetes mellitus. Methods 169 cases with type 2 diabetes mellitus were divided into two groups: 78 cases with constant high glucose(group Ⅰ) and 91 cases with glucose fluctuation state( group Ⅱ ). The clinical data such as fasting plasma glucose(FBG) ,fasting blood insulin(FINS) ,fasting blood C peptide,2 hours postprandial plasma glucose (2hPG) ,2 hours postprandial blood insuline (2hINS) ,2 hours postprandial blood C peptide, glycosy-lated hemoglobin A1c (HbA1c), and blood pressure (BP), body mass index ( BMI ), urinary albumin excretion rote (UAER) ,triglyeeride(TG) ,total cholesterol(TC) ,high density lipoprotein cholesterol(HDL-C) ,low density lipopro-tein cholesterol(LDL-C) were measured. Results 2hPG in group Ⅱ was much higher than that in group Ⅰ (P<0.01) ,but 2 hours postprandial blood insuline and 2 hours postprandial blood C peptide in group Ⅱ were much lower than those in group Ⅰ (P<0.01). The incidence of diabetic chronic complications was higher in group Ⅱ compared with that in group Ⅰ (P<0.01). Conclusion These findings suggest that glucose fluctuation state with type 2 dia-betes mellitus had increased diabetic chronic complications.

Objective To comprehend the metabolic disorder of the obese patients with type 2 diabetes mellitus(T2DM).Methods According to body mass index( BMI),176 cases of T2DM were divided into 2 groups;obesity(95 cases) and non-obesity(81 cases),the waist circumference(W) ,hip circumference(H) ,fasting plasma glucose(FBG) ,2-hour postprandial plasma glucose(2hBG) ,fasting blood insulin(FINS),2 hours postprandial blood insuline(2hINS), renal function, triglycetide(TG), total cholesterol(TC), high density lipoprotein cholesterol(HDL-C),low density lipoprotein-cholesterol(LDL-C ), glycosylated hemoglobin(HbA1c) and blood pressure(BP) were tested.Results The BMI,the ratio of W/H (WHR), serum uric acid (BUA), FINS, 2bINS, FCP and 2hCP in the obese group were higher than those in non-obese group(P <0.01);systolic blood pressure and diastolic blood pressure in obese patients were higher than those in the non-obese group(P >0.05) ,while the prevalence of abdorminal obesity.Hypertension significantly increased in obese group than those in non-obese group.Conclusion Among the T2DM ,metabolic disorder in obese patients is even more serious.It is very improtant for obese patients with T2DM to be given combined treatment to improve the metabolic disorder,that includes controlling blood glucose, decreasing weight and lightening insulin resistance.
