摘  要:目的研究白细胞VCS参数在血液细菌感染中的临床应用。方法采用Coulter LH 750血细胞分析仪检测120例血液细菌感染患者、69例非感染性发热患者、67名健康对照者的中性粒细胞和淋巴细胞的VCS参数,包括中性粒细胞平均体积(MNV)、中性粒细胞体积分布宽度(NDw)、中性粒细胞平均传导率(MNC)、中性粒细胞平均散射值(MNS);淋巴细胞平均体积(MLV)、淋巴细胞体积分布宽度(LDW)、淋巴细胞平均传导率(MLC)、淋巴细胞平均散射值(MLS)。将血液细菌感染组根据白细胞总数分为WBC≤10×10^9/L组和〉10×10^9/L组;根据中性粒细胞比例分为I〉85%组和〈85%组;根据细菌染色分为革兰阳性细菌感染组和革兰阴性细菌感染组。结果血液细菌感染组的MNV、NDW、MNS、MLV、LDW、MLC、MLS分另0为156±15、23.31±3.72、137±7、87±12、17.50±3.38、110±5、69±12;非感染性发热组分别为151±8、21.33±2.62、132±10、91±4、15.78±1.96、117±4、62±6;健康对照组分别为145±5、18.43±0.93、143±4、84±2、13.30±0.76、108±1、62±2;上述各指标在3组间差异均有统计学意义(F值分别为19.295、26.272、32.767、6.226、31.016、23.739、12.662,P〈0.05或〈0.01)。WBC≤10×10^9/L组MNV和NDW分别为152±16、22.19±3.45,WBC〉10×10^9/L组分别为159±12、25.29±3.43,与健康对照组比较,3组间差异有统计学意义(,值分别为21.575、40.856,P〈0.01)。中性粒细胞百分率/〉85%组的MNV、NDW分别为159±12、24.88±3.74,中性粒细胞百分率〈85%组分别为151±16、21.68±2.29,与健康对照组比较,3组间差异有统计学意义(F值分别为23.76、43.22,P〈0.01)。革兰阴性细菌感染组的MNV和NDW分别为157±15、24.25±3.39,革兰阳性细菌感染组分别为153±14、21.51±3.78,与健康对照组3组间�Objective To investigate the clinical application of VCS parameters of leukocyte in the detection of blood bacterial infection. Methods The subjects consisted of 120 patients with blood bacterial infection, 69 non-infectious fever patients and 67 health controls. The VCS parameters of neutrophil and lymphocyte were examined with Coulter LH 750 hematology analyzer. The parameters examined including mean channel of neutrophil volume ( MNV), neutrophil volume distribution width ( NDW), mean channel of neutrophil conductivity ( MNC ) , mean channel of neutrophil scatter ( MNS), mean channel of lymphocyte volume (MLV), lymphocyte volume distribution width(LDW), mean channel of lymphocyte conductivity (MLC) and mean channel of lymphocyte scatter (MLS). Additionally, 120 blood bacterial infection patients were grouped according to WBC count ( WBC ≤ 10 × 10^9/L group and WBC 〉 10 × 10^9/L group) , neutrophil rate ( ≥85% group and 〈 85% group) and bacterial stain ( Gram positive bacteria group and Gram negative bacteria group). VCS parameters among these groups were compared. Results The results of blood infection group were as follows: MNV 156 ± 15, NDW 23. 31±3. 72, MNS 137 ±7, MLV 87 ± 12, LDW 17. 50± 3.38, MLC 110± 5 and MLS 69± 12. The results of non-infectious fever group were as follows:MNV 151 ±8,NDW 21.33±2. 62,MNS 132 ±10,MLV 91±4,LDW 15. 78± 1.96,MLC 117 ±4 and MLS 62±6. The results of control group were as follows: MNV145 ±5 ,NDW 18.43 ±0. 93 ,MNS 143 ±4,MLV 84 ± 2, LDW 13.30 ± 0. 76, MLC 108 ± 1 and MLS 62 ± 2. There were significant differences among these three groups (F value were 19. 295, 26. 272, 32. 767, 6. 226, 31. 016, 23. 739 and 12. 662 respectively, P 〈0.05 or P 〈0. 01 ). In the infection group, the MNV and NDW were 152 ± 16 and 22. 19 ± 3.45 respectively for WBC ≤10 × 10^9/L group, 159 ± 12 and 25. 29± 3. 43 respectively for WBC 〉 10 × 10^9/L group. They were both significantly different compared wi
