ABSTRACT

Objective:To analyzed clinical characteristics of pituitary growth hormone(GH) adenomas patients with different responses to oral glucose inhibitory GH test.Methods:The clinical data of 50 patients with pituitary GH adenomas newly diagnosed with complete test data and case data in the Department of Endocrinology of Chinese PLA General Hospital was retrospectively analyzed from 2016 to 2021. The cases were divided into two groups according to the cutoff point of GH elevating to 50% of basaline during oral glucose test: abnormal elevation group(A group, n=16) and non-elevation group(B group, n=34). The clinical features, biochemistry, iconography, and immunohistochemistry of the two groups were analyzed. Results:The serum total cholesterol(TC)[(3.9±0.8) vs (4.6±0.9)mmol/L], 120 minutes insulin after glucose loading [11.2(4.4, 25.0) vs 92.0(10.8, 311.8)mU/L], long [1.0(0.4, 2.1) vs 1.5(0.5, 7.3) cm] and short[0.6(0.3, 1.3) vs 1.0(0.5, 5.8)cm] diameters of adenomas in A group were less than those in B group(all P<0.05) while insulin-like growth factor Ⅰ(IGF-Ⅰ) level was higher [(908.2±233.7) vs (743.1±273.1) ng/mL, P<0.05]. There were no significant differences in sex, age, disease course, clinical features, random GH, homeostasis model assessment of insulin resistance index(HOMA-IR), pituitary adenoma site, and invasive properties between the two groups. The immunohistochemical positive rates of ACTH(33% vs 0%) and prolactin(100% vs 28.6%)in A group were higher than those in B group( P<0.05). Conclusion:Pituitary GH adenomas patients with a paradoxical GH response pattern display lower serum TC and 120 minutes insulin levels as well as higher IGF-Ⅰ concentration and proportion of pituitary microadenomas. " Pure" growth hormone tumors may represent entities of a particular class of diseases in acromegaly.

ABSTRACT

Diabetes is the most important comorbidity of cardiovascular disease, and cardiovascular disease is the main cause of mortality and disability of patients with type 2 diabetes. In order to standardize the diagnosis and treatment of patients with diabetes and cardiovascular disease, the National Health Commission Capacity Building and Continuing Education Center organized the experts from the field of cardiology and endocrinology systematically reviewing the research progresses and expert experiences of relevant disciplines from home and abroad, and formulated this consensus. This consensus covers the diagnosis, drug treatment, and risk factor management for patients with diabetes and cardiovascular disease (including atherosclerotic cardiovascular disease and heart failure) from the perspective of cardiovascular disease and diabetes management aiming to strengthen the comprehensive management of patients and ultimately to improve the prognosis of patients. The management of cardiovascular diseases mainly includes the management of blood pressure, blood lipids, anti-thrombosis, anti-myocardial ischemia, anti-ventricular remodeling and so on. Diabetes management mainly includes lifestyle intervention (including diet, exercise, weight loss, etc.), anti-hyperglycemia therapy (including drugs and insulin), blood glucose monitoring, and hypoglycemic prevention. In addition, specific clinical recommendations are given to patients with special health care needs such as diabetic nephropathy, elderly (>75 years), and cardiovascular critical illness.

ABSTRACT

Objective To investigate whether brachial-ankle pulse wave velocity(baPWV),independently and jointly with the level of body mass index(BMI),affect the risk of incident diabetes with hypertension. Methods The effects of baPWV and BMI level on incident diabetes with hypertension were evaluated using Kaplan-Meier curves (log-rank test) and multi logistical regression models after adjustment for various confounding factors. Results A total of 2 222 participants were recruited in this study. Higher baPWV (Q4) was associated with a greater risk of incident diabetes with hypertension simultaneously compared with baPWV in the lower quartiles(Q1-Q3),with HR 4.16(95% CI 2.14,8.09)in the crude model,2.52(95% CI 1.10,5.78) in modelI,and 2.45(95% CI 1.05, 5.70)in modelⅡ.The highest risk of diabetes with hypertension simultaneously was in the group with high baPWV and BMI≥25 kg/m2,with HR 11.50(95% CI 4.5,29.9)in the crude model,4.20(95% CI 1.4,13.1)in modelI,and 4.30(95% CI 1.4,13.3) in modelⅡ. Conclusions The joint effect of baPWV and BMI level on incident diabetes with hypertension simultaneously is a better predictor than their independent effect. The risk of incident diabetes with hypertension markedly increases in the subjects with BMI≥25 kg/m2and higher baPWV.

ABSTRACT

Purpose To investigate the expression of miR-200a and PTEN in colorectal carcinoma (CRC) and their relationships with clinicopathologic features. Methods In situ hybridization and immunohistochemistry ( EnVision method) for miR-200a and PTEN were performed in 87 CRCs and normal colorectal tissues distant from tumors. Relationship between expression of miR-200a and PTEN and clinicopathologic parameters of CRC was also analyzed. Results The in situ hybridization showed that the positive expression rate of the miR-200a in CRC was higher than those in normal colorectal mucosa (P0. 05). The expression of miR-200a had a close negative correlation to that of PTEN in CRC (P<0. 01). Conclusions Overexpression of miR-200a might be associated with the occurrence and development by targeting PTEN, and they could be the indicators in the early diagnosis,treatment and prognosis of CRC.

ABSTRACT

Objective To probe the changes of plasma albumin concentration and its correlation with that of blood inflammatory factors at the postoperative early stage in patients undergoing intraabdominal surgery. Methods From August 2008 to March 2009, 45 patients undergoing abdominal surgery were divided into three groups according to different types of operation with 15 cases in each group, cholecystectomy group( A), chole cystectomy plus common bile duct exploration group(B) and radical resection of alimentary duct maliguance group (C). Before the surgery and 12,24,48,72 h after operation, plasma albumin contentserum IL-6 and TNF-α concentration were measured. Results Postoperatively the content of plasma albumin did not change significantly in group A ( P > 0.05 ), while that decreased after operation in group B and group C(P <0.01 ). The postoperative concentration of serum IL-6 and TNF-α increased in group A at 12, 24 h and 48 h after operation(P <0.01 ). In group B and group C IL-6 and TNF-α increased at all tested time point after operation ( P < 0.01 ). The postoperative alterations of IL-6 and TNF-α were statistically different between the three groups at all time points(P <0.01 ). The content of plasma albumin was in a negative correlation with the concentration of IL-6 and TNF-α; ( r = - 0.376, P = 0.000; r =-0.772,P = 0.000). Conclusions The content of plasma albumin decreased at the early stage after major and moderate abdominal surgery. The content of plasma albumin was in a negative correlation with the concentration of inflammatory factors at the early stage after abdominal surgery.

ABSTRACT

Objectives To explore the effect of transient continuous subcutaneous insulin infusion (CSII) on β cell function, insulin resistance and vascular endothelial injury in newly diagnosed type 2 diabetic patients and its potential mechanism. Methods Ten patients with newly diagnosed type 2 diabetes mellitus (T2DM) accepted CSII for two weeks. Intravenous glucose tolerance test (IVGTT) and hyperinsulinemia euglycemia clamp test were performed before and after CSII. Serum soluble E-selectin (sE-selectin) was used to evaluate the injury of vascular endothelial cell, while serum high sensitivity C reactive protein (hsCRP) and soluble CD_(14) (sCD_(14)) were both used to assess inflammatory condition. Results (1) Compared with those before treatment, the blood glucose levels of IVGTT, the area under the curve of the blood glucose, glycosylated hemoglobin, TC and LDL-C in the patients were decreased after CSII (P < 0. 05 or 0. 01). (2) Compared with those before treatment, the insulin levels of IVGTT (except the fasting insulin), the area under the curve of insulin and acute insulin response were all increased after CSII(P < 0.05 or 0.01). (3) Compared with that before treatment, the glucose infusion ratio in the clamp test [(3.46±1.66)mg·kg~(-1)·min~(-1) increased to (7.14±2.37)mg·kg~(-1)·min~(-1)]and HOMA-β elevated, while HOMA-IR declined (P <0. 05 or 0. 01 in all). (4) Compared with those before treatment, the levels of serum sE-selectin, sCD_(14) and hsCRP were decreased (P < 0. 01, except for hsCRP) . Conclusion Transient intensive insulin therapy in patients with newly diagnosed T2DM is useful to restore 13 cell function, attenuate insulin resistance, repair vascular endothelial injury and improve the disorder of blood sugar and lipid. The mechanism may be related with the inhibition of inflammation in patients.
