ABSTRACT
The aim of this study was to investigate the effect of erythropoietin (EPO) on the inflammatory response and the mechanism analysis of the Τoll-like receptor 4 (TLR4)/nuclear factor-κB (NF-κB) signaling pathway of NEC. A total of 94 patients with necrotizing enterocolitis (NEC) were randomly divided into the control (42 cases) and observation (52 cases) groups, The control group received the standard medical treatment plan, whereas for the observation group this treatment plan was combined with the application of recombinant EPO for intramuscular injection treatment. The clinical effect was subsequently compared. The results showed that the complication and death rates in the observation group were significantly lower than those in the control group with statistically significant differences (P<0.05). Following treatments, the levels of tumor necrosis factor-α (TNF-α) and interleukin (IL)-6 in the observation group were significantly lower than those in the control group. The expression levels of mRNA of TLR4 and NF-κB in the observation group were significantly lower than those in the control group, with statistically significant differences (P<0.05). In summary, EPO was able to reduce the levels of inflammatory response of TNF-α and IL-6 through the TLR4/NF-κB signaling pathway, and improve the NEC, thus providing a basis for the clinical treatment of NEC.
ABSTRACT
OBJECTIVE: To study the effect of recombinant human growth hormone (rhGH) therapy on carbohydrate, lipid and protein metabolisms of Turner syndrome (TS). Metho d s: Total 45 patients with TS admitted between Jul. 2008 and Jun. 2011 were involved in this study. All patients received the clinical evaluation of body fat, plasma lipids, proteins and oral glucose tolerance test (OGTT) before and after rhGH therapy. Results : Our results indicated a significant decrease of body fat (FAT%) from 23.56±4.21 to 18.71±2.23 but no obvious change on the level of fat mass (FM) (p>0.05) was observed after rhGH therapy. We also detected significant changes on plasma high-density lipoprotein cholesterol (HDL-C) from (1.65±0.58 mmol/L) to (2.20±0.65 mmol/L) and low-density lipoprotein cholesterol (LDH-C) from (2.55±0.55 mmol/L) to (2.10±0.54 mmol/L) after rhGH exposure. However, no statistical significance was detected on the level of plasma triglyceride (TG), cholesterol (CHO). Interestingly, the levels of plasma retinol binding protein (RbP) (32.55±4.28mg/L), transferrin (TRF) (2.95±0.40 mg/L), serum albumin (PRE) (250.00±45.50 mg/L) and albumin (propagated) (33.58±4.25 mg/L) were significantly increased. When it goes to the oral glucose tolerance test (OGTT) test, there were 10 impaired glucose tolerance (IGT) cases among all patients before and after rhGH therapy. No significant change was observed on homeostasis model assessment- insulin resistance (HOMA-IR) level during rhGH intervention. Conclusion : Abnormal lipid and protein metabolisms of the children with TS can be improved with rhGH therapy for 6 months.
