目的:探讨超敏C反应蛋白(CRP)和血常规联合检验在儿科疾病中的应用价值。方法:选取在广州市番禺区何贤纪念医院儿科接诊的72例住院感染患儿,对患者检查过程中主要采用超敏CRP白联合血常规检查为观察组。同时抽取同期本院儿科接诊的体检的75例,设为对照组。对hs-CRP和血常规联合检验结果进行分析。结果:治疗后观察组患儿外周血白细胞(14.05±7.24)×10~9/L,对照组患儿外周血白细胞(7.13±0.69)×10~9/L,组间对比差异具有统计学意义(t=8.856,P<0.05);观察组患者的超敏CRP为(14.25±3.08)mg/L,对照组儿童的超敏CRP为(2.75±0.12)mg/L,组间对比,差异具有统计学意义(t=7.902,P<0.05);治疗后7 d,观察组患儿超敏CRP为(2.84±0.83)mg/L,外周血白细胞为(7.32±2.13)×10~9/L,与治疗前对比,差异具有统计学意义(P<0.05)。结论:在儿科感染疾病临床诊断和治疗过程中,外周血白细胞和超敏CRP联合检测是一种简单、快捷的诊断方法,能够为临床诊断提供有效的依据。 Objective: To investigate the value of combined hypersensitive C-reactive protein (CRP) and blood routine test in pediatric diseases. Methods: A total of 72 inpatients with pediatric inpatient admissions at He Xian Memorial Hospital of Panyu District, Guangzhou City were enrolled in this study. The patients underwent primary ultrasonographic CRP combined with blood routine examination in the observation group. At the same time, 75 cases of physical examination of pediatric admissions during the same period were taken as control group. Hs-CRP and blood test results were analyzed. Results: The peripheral blood leukocytes (14.05 ± 7.24) × 10 ~ 9 / L in the observation group and the control group (7.13 ± 0.69) × 10 ~ 9 / L, the difference between the two groups was statistically significant (t = 8.856, P <0.05). The CRP in observation group was (14.25 ± 3.08) mg / L and that in control group was (2.75 ± 0.12) mg / L, the difference was significant (T = 7.902, P <0.05). At 7 d after treatment, the CRP in the observation group was (2.84 ± 0.83) mg / L and that of peripheral blood leukocytes was (7.32 ± 2.13) × 10 ~ 9 / L , Compared with before treatment, the difference was statistically significant (P <0.05). Conclusion: Combined detection of peripheral blood leukocytes and hypersensitive CRP during the clinical diagnosis and treatment of pediatric infectious diseases is a simple and quick diagnostic method, which can provide an effective basis for clinical diagnosis.
