Effect of sample processing at 56℃ for 30 min on routine examination in Department of Blood Transfusion / 中国输血杂志

【Objective】 To investigate the effect of sample processing at 56℃ for 30 min on routine examination in Department of Blood Transfusion. 【Methods】 A total of 40 cross matched blood samples submitted by clinical departments of our hospital, were collected, and each sample was equally divided into two. Before and after heating at 56℃ for 30 min, the ABO blood group was detected by manual method and card method (gel card and glass beadle card), antibody titer was detected by coagulant method, and cross-matching was conducted by anti-globulin card method. Chi-square test and Wilcoxon signed rank test were used to compare the differences between the two groups (before and after heating treatment). 【Results】 The blood group detection rates of the experimental group were 100% (40/40), 37.5% (15/40) and 80% (32/40) by manual test tube method, gel card and glass beads card, respectively, P0.05). The matching rate of two groups of samples, cross-matched with corresponding donor samples, was both 100% (40/40) by coagulant method, and 100% (40/40) vs 25% (10/40) respectively by the antiglobulin card method (P<0.01). The other 30 samples in the experimental group presented weak agglutination in the secondary side. 【Conclusion】 The treatment of virus inactivation at 56℃ for 30 min has little effect on blood group identification by test tube method, antibody titer and cross-matching by coagulant method, and reduceds the occupational exposure of staff in Blood Transfusion Department.

Clinical observation of speed-thorn Ghost-point combined with three-edged needle puncture bleeding and cupping in treatment for hyperplasia / 中国基层医药

Objective To investigate speed-thorn Ghost-point combined with three-edged needle puncture bleeding and cupping in treatment of breast hyperplasia in order to expand the scope of the treatment of Ghost-point.Methods 35 patients with breast hyperplasia were treated three courses with speed-thorn Ghost-point combined with three-edged needle puncture bleeding and cupping.The changes of breast pain and tumor size were observed before and after the treatment.Results 35 patients with breast hyperplasia were significantly improved in their symptoms of breast pain by Ridit analysis(P<0.01),and compared with those before treatment after treatment there was signifi-cant difference,and a total effective rate was 86%.Conclusion The speed-thorn Ghost-point combined with three-edged needle puncture bleeding and treatment of cupping could effectively reduce breast pain and tunlor size in pa-tients with breast hyperplasia,and the method was simple and curative effect.
