BACKGROUND
There is a close connection between type 2 diabetes mellitus and the risk of cancers and related mortality. The principal objective of the present study was to explore the association between type 2 diabetes and colorectal cancer. METHODS: We retrospectively compared 1111 subjects (age > or = 30 years) who were subjected to colonoscopies between June 2006 and June 2009. We evaluated the anthropometric data, presenting symptoms and signs, history of diabetes, laboratory data, colonoscopy findings and biopsy results. We analyzed the correlation between colorectal cancer and influencing factors, and compared the incidence rates of colorectal cancer in the type 2 diabetes and control groups. RESULTS: Four hundreds and seven of the subjects had diabetes mellitus. The incidence of colorectal cancer was increased significantly in type 2 diabetes relative to the control group (7.4% vs. 3.4%, P < 0.05). Colorectal cancer was correlated significantly with age, type 2 diabetes, constipation, anemia, and gastrointestinal symptoms. Following logistic regression analysis, age and constipation were associated significantly with colorectal cancer. In the age below 65 years subgroup, the incidence of colorectal cancer was increased significantly in the type 2 diabetes group relative to the control group. CONCLUSION: Type 2 diabetes was associated with increased colorectal cancer risk. This association was more definite in the subjects younger than 65 years.

BACKGROUND
It is known that patients with hypopituitarism have a high mortality rate due to the presence of atherosclerosis, cardiovascular diseases and stroke. The aim of this study was the effect of growth hormone (GH) on the atherosclerotic markers and the adipocytokine levels. METHOD: The study was conducted on 13 adult patients with hypopituitarism and growth hormone deficiency (GHD), and they had been stabilized after receiving hormone replacement therapy for other insufficient pituitary hormones, other than GH, for more than one year. Before treatment with GH, we compared the lipid metabolism, glucose metabolism, cardiovascular risk factors and adipocytokine levels, including adiponectin, leptin, TNF-alpha and IL-6, between the GHD patients and 13 healthy adults who were of a similar age and gender distribution. Patients with GHD were treated with 1 U/day of GH for 6 months. We measured insulin-like growth factor-I (IGF-I), blood pressure, body composition, lipid metabolism, glucose metabolism and hs-CRP, cardiac function, adiponectin, leptin, TNF-alpha and IL-6 levels, flow mediated vasodilation (FMD) and nitroglycerin mediated vasodilation (NMD) before and after GH treatment. RESULTS: The patients with hypopituitarism and GHD showed significantly higher levels of total cholesterol (P = 0.002), low-density lipoprotein cholesterol (LDL-C) (P = 0.036), hs-CRP (P = 0.0087) and leptin (P < 0.001) than did the normal healthy adults. However, there was no difference between the normal adults and the patients with GHD for the systolic and diastolic BP, the levels of apoA, apoB, fasting blood glucose(FBG) and HOMA-IR. In the subjects with GHD after treatment with GH, the level of fat mass (P = 0.0017), total cholesterol (P = 0.004), LDL-C (P = 0.001), leptin (P = 0.013), TNF-alpha (P < 0.001) and hs-CRP (P = 0.0001) were significantly reduced, while lean body mass (P = 0.0161), FFA (P = 0.049) and FMD (P = 0.0051) showed a significant increase. However, there was no significant difference in the level of the systolic and diastolic BP, LDL-C, apoA, apoB, LP (a), HOMA-IR, ejection fraction, left ventricular posterior wall, E/A ratio, intraventricular septum, NMD, intima-media thickness, adiponectin, IL-6, FBG and fasting insulin before and after GH treatment. CONCLUSION: The subjects with GHD were vulnerable to cardiovascular disease. GH therapy for 6 months had a positive effect on their various cardiovascular risk factors.

Abstract PDF: BACKGROUND
Osteoprotegerin(OPG) is a recently identified cytokine, which acts as a decoy receptor for the receptor activator of NF-B ligand(RANKL). OPG has been shown to be an important inhibitor of osteoclastogenesis and arterial calcification in animal models. Recently, OPG has been proposed as a link molecule between osteoporosis and arterial calcification. However, the relationship between circulating OPG levels and cardiovascular disease in human populations is unclear. Thus, the aim of this study was to investigate the relationship between circulating OPG levels and cardiovascular risk factors in women. METHODS: The subjects were 286 women, with a mean age of 51.5 yr. The blood pressure, body mass index(BMI) and waist to hip ratio(WHR) were examined and the serum concentrations of OPG determined by ELISA. The fasting glucose levels, serum lipid profiles and follicle stimulating hormone (FSH) were measured by standard methods. RESULTS: A significant association was observed between the serum OPG levels, age and WHR(r=0.134, P<0.05). Also, the serum OPG levels were significantly correlated with the serum total cholesterol and low density lipoprotein cholesterol levels(r=0.175, P<0.01; r=0.176, P<0.01). Conversely, there was a nonsignificant relationship between the serum OPG levels, blood pressure and fasting glucose levels. The mean serum OPG levels were found to be about 11% greater in post-than premenopausal women(mean+/-SD, 1358.5+/-380.0 vs. 1228.8+/-407.7pg/mL, respectively(P<0.001). There was a significant association between the serum OPG and serum FSH levels(r=0.176, P<0.01). CONCLUSION: In conclusion, our data show that the levels of circulating OPG are partially associated with the cardiovascular risk factors and female hormonal status in healthy women. These data suggest that OPG may be an important paracrine factor of cardiovascular disease in human female populations.

Abstract PDF: BACKGROUND
Pharmacological ACTH test provide information only about the ability of the adrenal gland to respond to unusual stimuli and may not reflect the daily cortisol secretion. There were some controversies in the diagnosis of mild adrenal insufficiency by using a pharmacological dose of ACTH. The purpose of the present study was to assess and compare the effect of low dose 1 pg ACTH and high dose 249 pg ACTH in the evaluation of adrenal function. The intravenous injection of a pharmacological dose(250 pg) of ACTH has been used as a standard test in the initial assessment of adrenal function. So we low dose ACTH to evaluate the adrenal function and compare the result of high dose ACTH. METHOD: Basal serum cortisol sampling was done at 2:00 p.m.. And after 1 pg ACTH iv bolus injection, cortisol sampling was done at 20, 30, 45 and 60 min respectively. On the next day same procedure was repeated at same time, but 249 mg ACTH was given instead of the low dose. Normal adrenal function was diagnosed with the criteria of stimulated serum cortisol concentration over 20 mg/dL. Total 65 patients took part in this study. Three hypopituitarism patients and one Addisons disease were included. Sixty-one patients had the history of glucocorticoid ingestion or had physical findings of cushingoid features with symptoms suggest the adrenal insufficiency. RESULTS: Sixteen patients showed normal response to both low dose and high dose ACTH. Thirty-six patients were not stimulated to both low dose and high dose ACTH. The remaining thirteen patients revealed normal response to high dose ACTH, but not to low dose ACTH. CONCLUSION: It appears that low dose ACTH stimulation test is more sensitive and specific than high dose ACTH and is capable of revealing mild adrenal insufficiency.

Abstract PDF: Cushings syndrome in pregnancy is rare. This is explained by the syndromes association with amencerhea, infertility and abortions. Matemal and fetal risks increase markedly when pregnancy does occur in woman with hypercortisolism. Since pregnant women without Cushings syndrome develop some features of Cushings syndrome, such as hypertension, hyperglycemia and striae, a high index of clinical suspician must be maintained to prevent delay in diagnosis. The physiologic changes in adrenocorticostemid metabolism during pregnancy further complieate the diagnosis. We describe a case of Cushings syndmme in pregnancy secondary to an adrenal cortical adenoma which was diagnosed immediately after a preterm delivery in 24-year-old woman with preeclampsia.
