Abstractobjective Diabetes mellitus is a common endocrinopathy in patients with b-thalassaemia major (b-TM), which is high prevalent in southern China. This study aimed to determine the cause and prevalence of glycaemic disorders in Chinese children with b-TM.methods In this prospective study, fasting glucose and insulin (FINS) levels were assessed in 267 b-TM and 80 non-TM control children. Homeostatic model assessment (HOMA) and the quantitative insulin sensitivity check index (QUICKI) were evaluated. Iron overload was assessed by serum ferritin (SF), total units of blood transfused and cardiac T2*.results b-TM had higher FPG (P < 0.001), FINS (P < 0.001) and HOMA-IR (P < 0.05), but lower QUICKI (P < 0.01) than those of controls. The impaired fasting glucose (IFG) was present in 30% of children, whereas 2% had diabetes. The prevalence of IFG in b-TM group was higher in children aged >10 years (OR 6.5; 95% CI 3.7-11.4; P < 0.001), SF of >2500 lg/l (OR 4.8; 95% CI 2.1-11.1; P < 0.01), serum ALT levels of >50 IU/l (OR 2.1; 95% CI 1.2-3.7; P < 0.05) and cardiac T2* of <20 ms (OR 3.3; 95% CI 1.7-6.6; P < 0. 01). The children on deferiprone (DFP) had a reduced incidence of glycaemic aberrations than those on other chelating agents (OR 0.4; 95% CI 0.23-0.8; P < 0.05).conclusions Our data suggest that IFG occurred in 30% of b TM children, perhaps due to insulin resistance secondary to iron overload. Deferiprone-containing chelating agent may have a protective effect.keywords thalassaemia major, iron overload, insulin resistance diabetes, cardiac load, short stature
Use of indwelling nephrostomy tubes with balloon after percutaneous nephrolithotomy can reduce blood loss. Further consideration for more widespread adoption of this type of tubing to limit perioperative bleeding complications is warranted.
Rab1A protein has been identified to be highly expressed in a number of malignant tumor tissues and to participate in the regulation of tumor development, but no data concerning bladder cancer have been described at present. The present study measured the expression of Rab1A in bladder cancer tissues and cell lines, and analyzed its clinical significance for patients with bladder cancer. A total of 153 pairs of bladder cancer tumor tissues and adjacent cancer healthy tissues were included in the present study. Western blot analysis and immunohistochemistry were used to measure the expression of Rab1A protein in normal bladder and bladder cancer cell line, and bladder cancer and normal adjacent tissues. SPSS 20.0 software was used for statistical analysis and mapping of survival curves in patients with bladder cancer. The expression levels of Rab1A protein in normal bladder cells and tissues was significantly decreased compared with that in bladder cancer cells and tissues, and it was significantly associated with tumor size, histological grade, tumor-node-metastasis (TNM) stage, lymph node metastasis and remote metastasis in 153 patients with bladder cancer. Cox regression analysis demonstrated that the expression of Rab1A protein in bladder cancer tissues was an independent risk factor for prognosis (overall risk=0.549; 95% confidence interval=0.139-0.916). The 5-year survival rate of patients with bladder cancer with high expression levels of Rab1A protein was 48.613%, which was significantly decreased compared with the rate of patients with low expression 75.31% (P<0.05). The expression of Rab1A in bladder cancer tissues and cell lines was upregulated, and its expression increased with increasing TNM stages. It was also associated with the metastasis of tumor cells and negatively affected the survival time of patients with bladder cancer.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
