目的 分析区级医院甲型流行性感冒患者的临床特征,为基层医院甲型流感的早期诊断及防控工作提供科学依据。方法 对2019年12月广州市番禺区中心医院发热门诊就诊的具有流感样症状的发热患者共628例,进行咽拭子甲型流感病毒核酸检测,收集患者临床资料,包括性别、年龄、体温、症状、血常规,根据核酸检测结果分为阴性组及阳性组,2组结果进行比较。结果 甲型流感病毒核酸检测阳性患者共116例,阳性率为18.5%。阳性组发病年龄以14～19岁所占比例最大,共91例(78.4%)。阳性组平均年龄小于阴性组(P＜0.05)。阳性组发病体温以38.1～39 ℃所占比例最大,共47例(46.5%)。阳性者平均体温高于阴性组(P＜0.01)。症状方面,阳性组仅鼻塞流涕比例较阴性组高(P＜0.05)。阳性组白细胞计数、中性粒细胞绝对值、淋巴细胞绝对值、淋巴细胞百分比均低于阴性组(P＜0.01)。结论 2019年冬季甲型流感患者以青少年为主,单纯症状较难区分甲型流感及普通感冒,需结合血常规特别是白细胞计数、中性粒细胞绝对值、淋巴细胞绝对值的降低进行分析。

Objective The clinical characteristics of patients with influenza A in district hospital were analyzed to provide scientific basis for early diagnosis, prevention and control of influenza A in primary hospital. Methods A total of 628 patients with influenza-like symptoms from Guangzhou Panyu Central Hospital in December 2019 were enrolled, and the clinical data was collected, including gender, age, body temperature, symptoms, and blood test results. According to the result of influenza A nucleic acid detection, patients were divided into negative group and positive group, and the clinical data of these two groups were compared. Results A total of 116 patients were positive in influenza A virus nucleic acid detection, which positive rate was 18.5%. In the positive group, patients aged 14-19 accounted for the largest proportion, with 91 patients (78.4%). The mean age of the positive group was significantly lower than that of the negative group (P＜0.05). Body temperature ranged from 38.1 to 39 ℃ accounted for the largest proportion in the positive group, with 47 patients (46.5%). The mean body temperature of the positive group was significantly higher than that of the negative group (P＜0.01). In terms of symptoms, only the proportion of nasal congestion in positive group was higher than that in negative group (P＜0.05). In terms of blood test results, WBC count, neutrophil absolute value, lymphocyte absolute value and lymphocyte percentage in the positive group were significantly lower than those in the negative group (P＜0.01). Conclusions The majority of patients with influenza A in the winter of 2019 were teenagers, and it was difficult to distinguish influenza A from the common cold only by symptoms. The differential diagnosis should be carried out in combination with the blood routine analysis, especially the decrease in the white blood cell count, the absolute value of neutrophil and the absolute value of lymphocytes.

Objective To investigate the diagnostic value of blood routine, erythrocyte sedimentation rate and C-reactive protein level in children with acute pneumonia. Methods A total of 100 cases of acute pneumonia in children admitted to our hospital from January 2014 to December 2019 were selected as the study group. At the same time, they were divided into an infected group (26 cases) and a non-infected group (74 cases) according to the presence or absence of infection. In addition, 100 healthy children examined in our hospital during the same period were selected as the control group. Blood routine examination, erythrocyte sedimentation rate (ESR), C-reactive protein (CRP) level were compared between infected and non-infected group; in infection and control group blood routine examination, ESR, C-reactive protein level were compared; in non-infection and control group blood routine examination, ESR, C-reactive protein level were compared. Results The percentage of neutrophils, white blood cell count and C-reactive protein in the infected group were higher than those in the non-infected group (P<0.05). There was no significant difference in erythrocyte sedimentation rate between the two groups (P> 0.05). The percentage of neutrophils, leukocyte count, C-reactive protein and erythrocyte sedimentation rate in the infected group were higher than those in the control group (P<0.05). There was no significant difference in the percentage of neutrophils and C-reactive protein levels between the two groups (P> 0.05), and the white blood cell count and erythrocyte sedimentation rate in the non-infected group were higher than those in the control group (P<0.05). Conclusion In the diagnosis of acute pneumonia in children, it is very important to detect the blood routine, erythrocyte sedimentation rate and C-reactive protein level in children, and it is worthy of clinical use.
