This study was purposed to confirm the practical efficacy of reducing indicating germs suspended in plasma by riboflavin and photosensitized inactivation and to evaluate its influence on activation of apheresis platelet concentrates. The synergistic effects of riboflavin combined with ultraviolet irradiation on inactivation of germs were investigated by using Escherichia Coli (E. coli) and Staphylococcus Aureus (S. aureus) as Gram⁻ and Gram(+) indicating germs, respectively. The activation status of apheresis-platelet concentrates treated with riboflavin combined with ultraviolet irradiation was detected by flow cytometry. The results showed that when 50 μmol/L of riboflavin was combined with 6.2 J/ml of ultraviolet irradiation, the T/E ratios reached 1.42 for E. coli and 1.68 for S. Aureus, and reduction of E. Coli and S. Aureus were 3.87 Logs and 3.82 Logs respectively; the CD62p expression level on germ-inactivated platelets stored at 22 degrees C for 0 and 5 days were 4.92% and 36.18% respectively, which slightly increased as compared with controls (3.94% and 32.03)% (p < 0.05). It is concluded that combination of riboflavin with ultraviolet irradiation displays well synergistic effects which can reduce E. Coli and S. Aureus counts, but no significantly influence on platelets. The partial activation of liquid platelets mainly presents metabolism damage during storage, which is found at an acceptable level.

Objective To analyze the general characteristics of voluntary blood donors, and to provide the basis for establishing effective recruitment mechanism. Methods The information of all whole blood donors (including mobile blood collection cars on the streets , blood donation houses and team blood donors) from 2006 to 2015 was obtained from the Zhejiang blood management information system. The sex, age, occupation, weight, and the amount of blood donation at a time of blood donors were descriptively analyzed. Results There were 5299700 frequencies of donating blood in Zhejiang Province from 2006 to 2015. The annual frequency was on the rise, with an average annual growth rate of 2.99％. There were 3098500 frequencies of male and 2201300 of female with the ratio of 1.4 :1. The frequency of female has declined since 2010. The majority of voluntary blood donors ranged from 18 to 45 years old, and the percentage was 91.44％ . The ratios of staff, students and workers were 14.61％, 12.27％, 10.09％, respectively. The annual frequency of staff was on the rise, with an average annual growth rate of 7.71％. The frequency of workers was on the decline, and the frequency of students fluctuated over the years. The ratio of blood donation 400 mL at a time was 41.23％. For 400 mL blood donation at a time, the ratio of male donors (48.86％) was significantly higher than the female donors (30.50％, P<0.001) . In addition, the ratio of blood donation 400 mL at a time was proportional to age and body weight (P<0.001) . Conclusion In Zhejiang Province, the frequency of blood donation has increased year by year. Staff, students and workers with 18 to 45 years old are the main force of blood donation. The frequency of female blood donation has a tendency of dropping, and the ratio of blood donation 400 mL at a time is relatively low. It's necessary to strengthen the propaganda of blood donation.
