血细胞活库支撑血细胞图谱计划和生态研究

生物样本活库相较于传统生物样本库,对“血液生态”具有更高的研究利用价值.通过对血细胞活库的规范化建设,我们构建了“数据+样本+X”的一体化管理模式,为血细胞图谱计划提供坚实的资源支撑.率先建立单细胞水平全套造血细胞分子指纹图谱,并成功创建了精细完整的血细胞单细胞数据共享平台.这些进展不仅为血液生理及相关疾病的研究提供了宝贵的研究资源和公共分析工具,而且为疾病的精准诊断和治疗提供新策略.

Effects of Probiotics on Growth Performance and Blood Biochemical Indexes of Cherry Valley Ducks

In order to investigate the effects of probiotics on growth performance, blood biochemical indexes and economic benefits of Cherry Valley ducks, different probiotics were added into the feed of Cherry Valley ducks. Total 240 1-d-old Cherry Valley ducks were selected, and they were randomly divided into 4 groups, including 1 control group and 3 treatment groups. There were 3 replicates for each group and there were 20 ducks for each replicate. The ducks in the control group were fed the basal diet, and the ducks in the 3 treatment groups were fed the basal diet added with Lactobacillus, Bacillus natto and florfenicol, respectively. The test lasted for 42 d. The results showed that the addition of Lactobacillus and Bacillus natto could improve the average daily weight gain and final average weight （P〈0.05） of Cherry Valley ducks, and reduce the glutamic-pyruvic transaminase ac- tivity, alkaline phosphatase activity and serum urinary nitrogen content in duck blood （P〈0.05） and reduce the creatinine content and total cholesterol content in Cherry Valley ducks （P〉0.05）; at the same time, adding probiotics to feed could also in- crease the grass economic benefits of Cherry Valley ducks. In overall, the effects of adding probiotics were better than those of adding antibiotic.

血液微生态环境代表性指标检测结果影响因素分析

目的探讨采血容器、检测时间等因素对血液微生态环境代表性指标检测结果的影响。方法采用不同采血容器(采血管和采血杯)分别在5、15、30和60 min采集受检者静脉血1次,经全自动分析仪对血液微生态环境代表性指标白细胞(WBC)、红细胞(RBC)、血红蛋白(HGB)和血小板(PLT)进行检测分析。结果不论是采用采血管还是采血杯,在5、15、30和60 min检测时血液微生态环境代表性指标WBC、RBC、HGB及PLT的结果比较差异无统计学意义(P>0.05)。结论不论是采用采血管还是采血杯采血,在1 h内检测,都不会对血液微生态环境代表性指标的检测结果造成较大影响。
