目的 分析银川地区单采献血者流失原因,制定回召策略。方法 对银川地区末次献血时间在2019年1月1日—2020年12月31日的1 498名单采献血者逐个致电回访,使用SPSS 26.0软件进行统计学分析,不同组间变量比较用χ²检验,P<0.05为差异有统计学意义。结果 成功召回355人(23.7%),和未召回组比较,性别无统计学差异(P>0.05),各年龄段、民族、职业、文化程度、血型之间均有统计学差异(P<0.05)。18～24岁、汉族、国家企事业单位、研究生及以上学历人群回召率最高;随着年龄增长、文化程度降低,回召成功率下降。未召回原因中工作繁忙占比最大,其次为在外地、身体原因、亲友献血者、失联、学生毕业、对献血误解、停车不便。结论 不断优化、细化单采献血服务,让工作更加人性化,加大献血正面形象的宣传,不断创新,从而保留固定献血者。

Objective To analyze the causes of apheresis blood donors loss in Yinchuan area, and to work out the call-back strategy. Methods A total of 1 498 blood donors whose last blood donation time was between January 1, 2019 and December 31, 2020 in Yinchuan area were called one by one. SPSS 26.0 software was used for statistical analysis. Variables between different groups were compared usingχ² test, and P<0.05 was considered statistically significant. Results Three hundred and fifty-five people (23.7%) were successfully called back. Compared with the failed call-back group, there was no significant difference in gender (P>0.05), but there were significant differences in age, nationality, occupation, education level and blood type (P<0.05). People aged 18-24, with Han Nationality, working in national enterprises or institutions, or with graduate degree or above had the highest call-back rate; with the increase of age and the decrease of education level, the success rate of call-back decreased. Among the reasons for call-back failure, no free time accounted for the largest proportion, followed by being in other places, physical reasons, donors of relatives and friends, losing contact, graduated from school, misunderstanding of blood donation, and inconvenient parking. Conclusion We will continue to optimize and refine the apheresis blood donation service, make the work more humanized, expand the publicity of the positive image of blood donation, and innovate constantly, so as to retain the blood donors.

Methods From January 20, 2020 to February 29, 2020, a retrospective analysis was carried out on 129 suspected cases of 2019-nCoV infection admitted to the isolation ward of the only medical unit designated for children in Guangzhou. The epidemiology, disease characteristics, clinical characteristics, laboratory examination, outcome and follow-up were summarized and analyzed. Results There were 79 males and 50 females, with a minimum age of 1 month and a maximum age of 13 years. Anong them, 51 cases (39.5%) had a history of tourism or residence in the epidemic area of Wuhan, 20 cases (15.5%) had a history of contact with people with respiratory symptoms from the epidemic area, 17 cases (13.1%) with a confirmed case in the surrounding area or community, 3 cases (2.3%) had a history of contact with a confirmed patient (2 of them were family clustering cases), 38 cases (29.5%) were clinically suspected cases. Clinical symptoms: 121 cases with fever (93.8%), 92 cases with coughing (71.3%), 50 cases with runny nose (38.8%), 32 cases with diarrhea, vomiting or abdominal pain (24.8%). In 102 cases (79.0%), white blood cells were decreased or normal, 103 cases (79.8%) with CRP＜20 mg/L, and 57 cases (44.2%) showed focal infection on chest X-ray or CT scan. Etiological examination: only one case (0.78%) of the family confirmed cases had positive anal swab result, but the throat swab results were negative all the time. The anal swab and throat swab results of other patients and the throat swab results of their accompanying family members were negative. Other pathogens were detected in 61 cases (47.3%), including 14 RSV positive cases, 9 influenza A positive cases, 8 human metapneumovirus positive cases, 6 enterovirus positive cases, 6 influenza B positive cases, 6 Mycoplasma pneumoniae positive cases, 4 parainfluenza virus type 1 positive cases, 1 parainfluenza virus type 3 positive cases, 2 human bocavirus positive cases, 3 adenovirus positive cases, 1 Klebsiella pneumoniae positive cases, 1 Human Staphylococcus positive case, and 1 case with parainfluenza virus type 1 and human bocavirus. The only confirmed patient was followed up while multiple pharyngeal swab results were negative, and the positive anal swab results lasted for 19 days before turning negative and remained asymptomatic. Other patients were followed up on the 3rd, 7th and 14th day after discharge, and no abnormal findings were found. Conclusion Screening/suspected cases of 2019-nCoV infection in children were mostly clinically manifested as respiratory or gastrointestinal symptoms. The diagnosis rate of nucleic acids was extremely low, and there was a possibility of missed diagnosis. Nearly 50% of cases could find other relevant pathogens excluding the 2019-nCoV. The positive rate of anal swab results was higher than that of pharyngeal swab.

Objective Through blood analysis and C-reactive protein (CRP) level detection, to explore its value in the auxiliary diagnosis of influenza A and B in children, and to provide reference for clinical treatment. Methods 3 069 children with influenza A, 2 307 children with influenza B, and 855 healthy children were selected, and blood routine parameters and CRP levels were statistically analyzed. The ROC curve was used to analyze the discriminatory efficacy of blood routine on influenza A and B. Results The mean value of white blood cell count (WBC) in group A was higher than that in normal group, but in group B it had the opposite result. The percentage of neutrophils (Neut%), the ratio of neutrophils to lymphocytes (NLR), and the percentage of monocytes (the mean value of Mono%) is higher than that of normal group, and the mean value of lymphocyte percentage (Lymph%) and platelet count (PLT) of group A and B is lower than that of normal group. The mean values of neutrophil count (Neut#), monocyte count (Mono#), CRP and PLT in group A were higher than those in group B, and the mean values of Lymph% and lymphocyte count (Lymph#) were lower than those in group B. The composition ratios of group A in WBC>13×10⁹/L, Neut%>70.7, Lymph%<19.1 were higher than that in group B. The NLR predicted the critical value of influenza A was 2.08 (sensitivity 75.9%, specificity 89.4%), and the predicted influenza B threshold value was 2.11 (sensitivity 50.5%, specificity 89.8%). Conclusion Changes in blood routine parameters and CRP levels can be used to determine whether there is a bacterial infection in children with influenza and to guide clinical medication; NLR as a new predictive marker, its changes can distinguish influenza A or B. Especially in influenza A determination, it has clinical value.
