Résumé
【Objective】 To understand the situation of free blood use of blood donors in Changsha to explore the correlation between free blood use of donors and repeated blood donation behaviors, so as to provide a theoretical basis for the recruitment of voluntary blood donations. 【Methods】 A total of 260 voluntary blood donors were selected by random sampling and divided into reimbursed group(n=97) and unreimbursed group(n=163), based on the results of a questionnaire, inquiring their using of free blood. 【Results】 The reimbursed group differed from the unreimbursed group in all dimensions, including behavioral attitude dimension(Z=3.250, P<0.05), subjective behavioral norm dimension(Z=4.576, P<0.05), and perceptual behavioral control dimension(Z=7.255, P<0.05) and the total score of the scale(Z=8.625, P<0.05), and the differences were statistically significant. 【Conclusion】 The intention to donate again was stronger in donors who experienced free blood use than those didn’t. Such donors are suitable candidates for blood donor recruitment. It is recommended to develop a suitable recruitment strategy for this population and further guarantee the clinical use of blood.
Résumé
OBJECTIVE: To investigate the curative effects and side effects of hirudin in treating immunoglobulin A nephropathy (IgAN) with hematuria and minimal proteinuria in a short-term. METHODS: Two hundred and sixty-two histologically confirmed cases of IgAN with hematuria and minimal proteinuria from 1998 to 2007 were randomly divided into hirudin-treated group (peroral administration of Maixuekang capsules) and dipyridamole-treated group (peroral administration of dipyridamole). In the two groups, contrast analysis of conformation and counts of erythrocytes in urine, urine protein quantitation in 24 hours, levels of serum creatinine (Scr) and creatinine clearance rate (Ccr), blood lipid, five items of blood clotting and side effects was performed. RESULTS: After six-month treatment, the anisotrophy rate and the counts of erythrocytes in urine, and the urine protein quantitation in 24 hours in hirudin-treated group were decreased distinctly as compared with pre-treatment (P<0.01) and dipyridamole-treated group (P<0.05). On the other hand, Ccr was increased obviously in hirudin-treated group as compared with pre-treatment and dipyridamole-treated group (P<0.01). The blood lipid was also ameliorated in hirudin-treated group, but there was no significant difference. The anticoagulation effect of hirudin was better than dipyridamole (P<0.01). Efficacy assessment showed that the total response rate, complete remission rate and predominance remission rate in hirudin-treated group were higher than those in dipyridamole-treated group. Few side effects were found in both groups, and the rate of adverse reaction in gastrointestinal tract was lower in hirudin-treated group as compared with that in dipyridamole-treated group (P<0.05). CONCLUSION: Compared with dipyridamole, hirudin has superiority in kidney protection and decreasing the anisotrophy rate, counts of erythrocytes in urine and the urine protein.
