Objective To explore the effects of high insulin and high glucose concentrations on glucose transport activity,the expression of insulin signaling peptides and glucose transporter 4(GLUT4) translocation in primary cultured rat adipocytes.Methods Isolated rat adipocytes were cultured for 24h at insulin(10 4?U/ml) and different concentration glucose(5,10,15 and 25mmol).Then the glucose uptake,cellular contents of insulin receptor substrate(IRS) 1/2,phosphatidylinositol 3-kinase 85 subunit(p85),protein kinase B(PKB) and GLUT4 were measured by Western blotting method.Results These adipocytes treated with insulin and different high concentration glucose had shown to impair glucose uptake in a dose-dependent manner,inhibited cellular IRS1 expression,impaired IRS2 protein expression independent on glucose concentration in the medium,it did not influence the contents of p85,PKB and GLUT4,but decreased GLUT4 translocation.Conclusions Chronic high insulin induced insulin resistance may be caused by the increasing glucose concentration surrounding the cells.The mechanism may be involved in affecting IRSs protein expression and GLUT4 translocation.

Objective To explore the impact of nursing intervention on the visual quality of patient after excimer laser refractive correction operation. Methods 400 patients, underwent excimer laser refractive correction operation and regularly followed up more than 6 months, were selected in our hospital from January to December in 2010. The clinical data of 200 patients without nursing intervention were analyzed as control group compared with those of 200 patients receiving nursing intervention as intervention group. Both groups were conducted routine nursing instruction before the operation. The intervention group was given systematic and normative nursing intervention besides routine nursing instructions, including psychological intervention, behavioral intervention, close observation, discovery of adverse reaction in time and giving early disposal. The cooperation reaction of the patients during the operation, and incidence of surgical complications during and post surgery were observed. Results Compared with the control group, the incidence of adverse reactions of visual influence such as incomplete valve during surgery, eccentric cutting after surgery, overcorrection, glare, and refractive regression were significantly lower (P<0.05). Conclusion The implementation of nursing intervention can reduce the adverse reaction of excimer laser refractive correction operation, alleviate the suffering of patients and promote visual quality after surgery.

Objective To explore the effect of glucocorticoid on glucose transport activity and the expression of insulin signaling peptides in the primary cultured rat adipocytes .Methods Isolated rat adipocytes were cultured for 2h,8h,16h and 24h respectively at 5 mmol glucose with dexamethasone (Dex) 0 3?mol. Then the glucose uptake, cellular contents of insulin receptor substrate (IRS) 1/2, phosphatidylinositol 3-kinase 85 subunit (p85) and protein kinase B(PKB)were measured by Western blotting.Results These adipocytes treated with Dex have shown to impair the basal and insulin-induced glucose uptake with a maximum inhibition at 2h and 24h respectively; Dex down-regulated IRS1 protein expression in a time-dependent manner and up-regulated IRS2 content. The cellular p85 and PKB contents were also decreased by Dex. Conclusion Chronic exposure to glucocorticoid can inhibit glucose uptake and induce insulin resistance. The mechanism may be involved in affecting the expression of insulin signaling peptides.

Objective To explore the effects of high glucose on glucose transport activity, and phosphorylationandexpressionofinsulinsignalingproteins in primary cultured rat adipocytes. Methods Isolated rat adipocytes were cultured at different glucose concentrations (5, 10, 15, 25 mmol/L) for 24 h. Then the glucose uptake, the phosphorylations of insulin receptor (IR), insulin receptor substrate (IRS) 1 and 2 and protein kinase B (PKB) as well as the protein expressions of IRS1, IRS2, p85 subunit of phosphatitylinositol 3 kinase (p85) and PKB were measured. Results These adipocytes treated with different high glucose showed the impairment of the basal and insulin induced increase in glucose uptake and significant decrease of IR, IRS1 and PKB phosphorylations as well as IRS1 protein expression, but up regulation of IRS2 protein expression. p85 and PKB contents and IRS2 phosphorylation were unaffected. Conclusion The exposure to high glucose inhibits glucose uptake and induces insulin resistance in adipocyte. The mechanism may be involved in affecting the multiple step phosphorylations and the expressions of insulin signaling proteins.

Objective To explore the molecular mechanism of glucocorticoid and high glucose-induced insulin resistance(IR).Methods Isolated rat adipocytes were cultured for 24h at 5 or 25 mM glucose with or without dexamethasone (Dex) 0 3?M. Then the glucose uptake , the phosphorylation of tyrosine of insulin receptor substrate (IRS)1/2 and expression of IRS 1/2 and protein kinase B(PKB) protein were measured by western blot analysis with molecular dynamics. Results These adipocytes treated with 25 mM glucose have shown to impair glucose uptake, IRS1 phosphorylation and the protein expression; Combined treatment with Dex enhanced high glucose-induced the suppression, and inhibited IRS1 tyrosine phosphorylation; High glucose increased IRS2 protein expression, Dex abolished partly its the effect. Conclusions High glucose can induce IR, Dex can aggravate the effect induced with high glucose. The mechanism may be involved in affecting the phosphorylation and expression of insulin signaling proteins.
