Significance of changes of peripheral blood cells and T-lymphocyte subgroups in patients with aircondition disease

Abstract

Objective To discuss the metabolic characteristics and significance of peripheral blood cell and T lymphocyte subgroup in patients with air condition disease.Methods Thirty-six patients diagnosed as air condition diseases with fever and 30 patients diagnosed as non-fever patients enrolled this study as observation group(fever group and non-fever group respectively),and 30 health population were used as control.The changes of peripheral blood cell and T lymphocyte was measured using regular blood examination and flow cytometry.Results(1)No significant diffence on white blood cell was found between the three groups(F =1.89,P =0.134);(2)The percentage of neutrophils was(68.13 ±5.67)％,(53.24 ±8.36)％ and(61.25 ±6.31)％ respectively in the fever,non-fever and control group,respectively.Compared to the non-fever and control group,the percentage of neutrophils were significantly higher(t =6.64,9.13; P =0.018,0.027 respectively).No signiciant difference in the percentage of neutrophils was found between the non-fever group and control group(P =0.356,0.125).The percentage of lymphocyte percentage was(31.66 ±7.11)％,in the fever group,which was significantly higher than those of(43.67 ±8.17)％ and(30.98 ± 8.76)％ in the nonfever and control group(t =5.59,4.98 ; P =0.022,0.021 respectively).(3)The percentage of CD4 + was (36.351 ± 6.531)％,(42.676 ± 5.169)％ and(39.253 ± 5.461)％ in the fever,non-fever and control group,respectively.The percentage of CD4 + in the fever group was significantly lower than that in the non-fever group(t =1.28,P =0.039),whereas the percentage of CD4 + in the non-fever group was significantly higher than that in the control group(t =3.80,P =0.048).The percentage of CD8 + was(28.084 ± 7.344)％,(21.186 ± 6.331)％ and(24.607 ± 7.108)％,respectively.Compared to nonfever group,the percentage of CD8+ was significantly higher(t =3.17,P =0.016).(4)The ratio of CD4 +/CD8 + was(1.629 ±0.554)％、(2.380 ± 0.391)％,and(2.079 ± 0.659)％.Compared to the non-fever and control group,the ration in the fever group was siginificantly lower(t =19.21,P ＜ 0.001 ; t =6.98 ; P =0.006),whereas compared to the control group,the ratio in the non-fever group was significantly higher(t =8.68,P =0.031).Conclusion The changes of T subgroup show the unbalance immunity function network in patients with air condition disease.
