ABSTRACT
Objective To observe the effect of Aquacel AG dressing in treating diabetic foot and nursing measures.Methods Seventy-nine hospitalized patients diagnosed as diabetic foot were enrolled,and 45 of them were chosen randomly as the experimental group,who was treated with Aquacel AG dressing,and changed the dressing per 3 to 5 days.The other 34 patients were named as the control group,who was treated with normal cotton dressing by wet compress,and changed the dressing one time per day.The total effective rate and healing condition were compared between the two groups.Results The total effective rate of the experimental group was 93.3％,higher than that of the control group (79.4％) significantly.The healing time of the experimental group was (64±10)days,shorter than that of the control group,(88±12)days.Conclusions Aquacel AG dressing was suggested to use in treating diabetic foot.
ABSTRACT
Objective To discuss the effects of high glucose on human mesangial cells (HMC)Wnt-β-catenin signaling pathway,and the intervention of rhein on it.Methods High concentration of glucose (30 mmol/L) combined with different concentrations of rhein were used to intervene cultured human mesangial cells.The activity of mesangial cell proliferation after all the interventions was examined by MTT measurement.Total Wnt、β-catenin RNA was detected By RT-PCR in normal mesangial cells and cells intervened by high glucose and Rhein.Results ①Inhibition effect to human mesangial cells:compared with NG group for 24 h,48 h and 72 h (OD values were 0.169± 0.051,0.228±0.074,0.285±0.075),human mesangial cells proliferation in HG group(OD values were 0.307± 0.074,0.507 ±0.038,0.711±0.075),HG+R1 group(OD value were 0.241± 0.027,0.334±0.015,0.499±0.063),HG+R2 group (OD value were 0.244±0.081,0.386±0.033,0.531±0.011),and HG+R3 group(OD value were 0.277±0.036,0.407± 0.057,0.594±0.042) were iucreased significantly (P＜0.05、P＜0.01) ; Compared with HG group for 24 h,48 h and 72 h,the HG+R1 group,the HG+R2 group and the HG+ R3 group showed a downward trend at 24 h,but not significantly; but the trend decreased significantly at 48 h and 72 h,and the performance expressed a time,concentration-dependent (P＜0.05,P＜0.01).② In the normal state,the mesangial cells expressed s certain amount of Wnt and β-catenin,when they were stimulated by high glucose,the expression of Wnt、β-catenin in mRNA increased (P＜0.05) ; while the expression of them was significantly reduced in high glucose-induced mesangial cells in HG+R1 group,HG+R2 group and HG+R3 group(P＜0.05).Conclusion Rhein may inhibit the proliferation of high glucose-induced mesangial cells through the Wnt and β-catenin gene expression.
