目的 探索连续捐献机采血小板献血者血小板、白细胞和红细胞计数变化情况。方法 以2016年1月1日—2018年9月30日年期间首次献血且连续血小板捐献量在10 U及以上的849人为研究对象进行回顾性研究,采用同一群体的配对t检验来评估第一次与最后一次血小板、红细胞及白细胞计数的变化情况。将采用有序多分类Logistic回归分析调查期间的血小板捐献量对献血者外周血细胞计数的影响。结果 配对t检验表明,外周血PLt有增加趋势(t=-8.58,P<0.001);白细胞总体来说有减少趋势(t=5.348,P<0.001);红细胞无改变趋势(t=0.515,P=0.607);有序多分类Logistic回归分析结果显示:PLt的变化值与献血者年龄、性别以及第一次与最后一次献血的间隔期无关系,P＞0.05;但是与血小板捐献量41 U及以上比起来,血小板捐献量在≤30 U的献血者,血小板计数增加的可能性相对较少(血小板捐献量为10～20 U,χ²=13.737,P<0.001;血小板捐献量为21～30 U,χ²=7.491,P=0.006);WBC的变化值与献血者年龄、性别及献血间隔期无关,P＞0.05,但是与血小板捐献量41 U及以上比起来,血小板捐献量在10～20 U的献血者,白细胞计数增加的可能性相对较大,(OR=1.720,95%CI=1.136~2.605,P=0.010) RBC的变化值与献血者年龄、性别无关(P＞0.05);第一次与最后一次献血间隔期越长,红细胞计数增加的可能性就越大,(OR=1.005,95%CI=1.000~1.009,P=0.030);但是与血小板捐献量并无关系。结论 血小板捐献间隔期不少于2周间隔期的连续血小板献血者,其外周血PLt和RBC在一定时间内变化情况会受到血小板捐献量的影响而发生增加和减少的变化,但均在正常范围内波动。

Objective To explore the changes of platelet, white blood cell and red blood cell counts of long-term platelet blood donors. Methods A retrospective study was conducted on 849 platelet blood donors who donated for the first time and continuously donated amounts to 10U plateletor or more from January 1, 2016 to September 30, 2018.The paired t test of the same group was used to evaluate the changes of platelet, red blood cell and white blood cell counts between the first time and the last time donation during the study period. Ordinal multinomial logistic regression was conducted to analyze the effects of platelet donation on the peripheral blood cell count of the donor during the survey. Results Paired t-test result showed that there was a increase in PLt (t=-8.58, P<0.000 1);a decrease in WBC(t=5.348, P<0.000 1); and no significant change in RBC (t=0.515, P=0.607).The results of ordinal multinomial logistic regression analysis showed that the change in PLt had no relationship with age, sex, and interval between the first and last blood donation, P>0.05. Compared with donors who donated 41U or above,the possibility of an increase in platelet count was relatively small for those who donated 30U or below(platelet donation amount 10~20U,χ²=13.737,P<0.000 1;platelet donation amount 21～30U,χ²=7.491,P=0.006). There was no relationship between age, gender, and blood donation interval and WBC changes, P>0.05. Compared with donors who donated 41U or above, WBC was more likely to increase for those who donated 10～20 U (OR=1.720, 95%CI=1.136~2.605, P=0.010).RBC changes had nothing to do with age, gender and platelet donation amount of the blood donor, P> 0.05; the longer the interval between the first and last blood donation took, the more likely the red blood cell count increased, (OR=1.005, 95%CI=1.000~1.009, P=0.030). Conclusion For continuous platelet donors with platelet donation intervals of no less than 2 weeks, platelet donation amount will affect the peripheral blood counts,and all the blood conuts are within the normal range.

Objective To explore the clinical effect of super gamma knife in the treatment of advanced pancreatic cancer. Methods 46 patients with advanced pancreatic cancer admitted to our hospital from January 2015 to January 2019 were randomly divided into control group (23 cases)and observation group (23 cases). The control group received chemotherapy only; the observation group received super gamma knife treatment. We collected the clinical benefit response (CBR)and other indicators of treatment efficiency and survival time of the two groups for comparative analysis. Results One month after the intervention of different treatment measures, the total effective rate of the two groups was compared. The total effective rate of the observation group was 60.87%, which was higher than that of the control group (13.04%)(P<0.01). The positive rate of pain degree improvement, KPS physical strength improvement, body weight improvement in the observation group were all higher than those in the control group (P<0.05), but there was no statistical significance between the two groups in the positive rate of analgesic consumption improvement (P>0.05). The median time of progression free survival was 4 months (95% CI, 2.124±5.274)in the observation group and 3 months (95% CI, 1.804±4.851)in the control group. The median time of progression free survival in the observation group was longer than that in the control group (P = 0.042<0.05). Conclusion The super gamma knife based on the stereotactic gamma ray systemic therapy system uses the medium dose segmentation method to treat the advanced pancreatic cancer. Its clinical effect is practical, the side effects are relatively low, and the survival treatment of patients has a significant improvement effect, which is worthy of clinical promotion.
