ABSTRACT
Objective Discussion leukoreduction of red blood cells suspended in two different storage bag placement and he-molysis rate impact on the supernatant free hemoglobin (FHb),to ensure the clinical transfusion is safe and effective.Meth-ods Selected 20 donors to sample 400 ml whole blood per person to make leukodepleted red blood cells,which were evenly divided into 10 bags.The 10 bags were randomly divided into two groups,one to the upright position,one group of horizon-tal.The two groups were stored under the same conditions.Respectively,in the 7,14,21,28,35 day,randomly removed one storage bag from each group,FHb and red blood cell hemolysis rate were measured and analyzed statistically.Results FHb and hemolysis rate results stored in the first 21 days of testing,uprightgroup were (217.310±48.477)mg/L and (0.250± 0.056)%,respectively horizontal group (173.972±39.027)mg/L and (0.189±0.045)%,the results set upright than hori-zontal group,the results were statistically(t=3.114,P =0.003<0.05 and t=3.798,P =0.001<0.05),the difference was statistically significant.Conclusion In the blood storage period,storage bags can be placed horizontally to reduce the de-struction of red blood cells,blood storage is more favorable.
ABSTRACT
Objective To analyze the outcome of patients receiving intrauterine insemination with husband sperm,in order to evaluate the effect of relative factors on pregnancy rate after intrauterine insemination. Methods Ninety-eight infertile couples who received intrauterine insemination in the Affiliated Hospital of Nantong University from March 2013 to May 2014 were selected as our subjects and 181 cycles were included. The information including clinical factors including maternal age,infertile time,infertile causes, ovulation induction protocol,time of insemination and postwash total motitle sperm(TMS)and pregnancy rate were recorded. Results (1)Totally 26 patients received clinical pregnancies,and clinical pregnancy rate(CPR) was 14. 36% per cycle. With age increase pregnancy rate decreased( χ2 = 1. 654 9,P = 0. 647).(2)The pregnancy rate of the patients was the same within the infertile time( χ2 = 1. 588 5,P = 0. 662).(3)The pregnancy rate of the patients with secondary infertility was lower than that of the patients with primary infertility,but there was no significant difference(χ2 = 0. 923 3,P = 0. 337).(4)The pregnancy rate of ovulation induction cycles was lower than that of nature cycles,but there was no significant difference(χ2 = 2. 222 0,P= 0. 136).(5)Postwash TMS was showed the same trend(χ2 = 0. 643 4,P = 0. 422). Conclusion In terms of intrauterine insemination with husband sperm,age,infertile time,infertile types,ovulation induction protocol and posrwash TMS can affect pregnancy rate,and the effects of various factors should be considered comprehensively in the process of therapy.
