ABSTRACT
Objective To investigate the correlation among mean platelet volume (MPV) ,serum vitamin D (VD) and immuno-globulin E(IgE) level .Methods A total of 775 children patients in our hospital were selected and grouped according to MPV ,VD and IgE levels .The corresponding detection methods were adopted to detect MPV ,VD and IgE levels .Methods The correlation a-mong these 3 indicators was analyzed .Results The MPV level had statistical difference among the groups with different VD levels (P<0 .05) ,and the MPV level had statistical difference among the groups with different IgE levels (P<0 .05) .The MPV level was negatively correlated with the VD level(r2 =0 .026 ,P<0 .01) ,the MPV level was positively correlated with the IgE level E (r2 =0 .008 ,P<0 .01)and the IgE level and VD level had negative correlation (r2 =0 .08 ,P<0 .01) .Conclusion The VD level is nega-tively correlated with the MPV and IgE levels ,the positive correlation exists between IgE level and MPV level .VD supplement can inhibit platelet activation and inflammation reaction ,and has significant clinical value in the prevention and treating hypersensitive reactive diseases .
ABSTRACT
Objective To determine normal reference ranges for venous blood count among children aging from 1 year old to 12 years old.Methods These normal reference ranges were defined in a population of 526 healthy children who had no blood system diseases,allergic diseases,respiratory system diseases,urinary system diseases,digestive system disease,rheumatoid disease,thyroid disease,parasitic infections,malignancies and genetic disease,etc.Values of white blood cell count (WBC),red blood cell count (RBC),hemoglobin (Hb)concentration,red blood cell specific volume (Hct),mean corpusular volume(MCV),mean cell hemoglo-bin (MCH),mean corpuscular hemoglobin(MCHC),platelet (PLT),percentage of neutrophil (NE%),percentage of lymphocyte (LY%),percentage of mononuclear cells (MO%),percentage of acidophilic granulocyte (EOS%).Statistical analysis was done on various parameters that we recorded,and then for every parameter,we could get the various reference ranges for different age groups.Results The subjects were divided into 4 groups based on age.Besides the parameters of WBC count and classification of WBC,the rest of parameters were proved to be of no statistical difference between 4 groups..After an integration of the values,we could get the results as follows:RBC(4.02-5.2)×10 1 2/L,HGB 108-144 g/L,Hct 35.2%-40.4%,MCV 74.6-89.9 fL,MCH 20.9-34.7 pg,MCHC 332- 340 g/L,PLT(157 - 409 )× 10 9/L.WBC count did not have statistical difference between the age group 6-<9 and 9-12,but did have between the rest groups.After an integration of the values of WBC count,it could be conclu-ded that WBC count of age group1-<3 was(4.88-13.38)×10 9/L,that of age group 3-<6 was(4.26-1 1.6)×10 9/L and that of age group 6-12 was (4.24-10.24)×10 9/L.WBC classification results were various in different age groups.The values showed as follows:age group 1-<3 NE:29%-32%,LY:58%-61%;age group 3 -<6 NE:43%-46%,LY:43%-46%;age group 6-<9NE:49%-52%,LY:38%-40%;age group 9 to 12NE:5 1% - 58%,LY:33% - 39%.Conclusion WBC classification re-sults and WBC count do have statistical difference in different age groups.Besides the parameters of WBC count and classification of WBC,the rest of parameters are proved to be of no statistically difference in different age groups.The values of WBC count decrea-ses as the age increases.From WBC classification results,the most apparent fact is that the percentage of neutrophil increases as the age increases but the percentage of lymphocyte is just the contrary.As mentioned above,we suggest that we should establish a spe-cific whole blood count normal reference range for each age group during our laboratory testing work.
