Objective To investigate and understand the reference value range of hematological parameters for peripheral blood routine in preschool children from Shanghai.Methods The Sysmex XS-800i automated hematology analyzer and the original rea-gents were used to measure the hematological parameters in peripheral blood samples collected from 7 692 healthy preschool chil-dren aged 2-6 years in Shanghai,including white blood cells(WBC),red blood cells(RBC),platelet(PLT)count,hemoglobin(Hb), hematocrit(HCT),mean corpuscular volume(MCV),mean corpuscular hemoglobin(MCH)and mean corpuscular hemoglobin con-centration(MCHC);the various parameters in different age groups were collected and statistically processed to establish the refer-ence intervals for each parameter.Results In the blood routine among preschool children in Shanghai,there were statistically signif-icant differences in all parameters except WBC and PLT count between sexes among preschool children in Shanghai(P <0.05).The reference intervals of hematological parameters obtained in this investigation were obviously differed from those offered by the man-ufacturer.However,compared with those from the related reports,the difference existed in partial parameters,the upper limit of WBC count was highest compared with the results from some areas,while the reference value ranges of MCV,MCH and MCHC were higher than those of other area study results.Conclusion The independent blood routine medical reference value range for preschool children in Shanghai should be established and the influence of the factors of gender,instrument and reagents also should be taken into consideration in establishing the reference value range.

Objective To explore the correlation between 18F-FLT SUVmax and intratumoral microvessel density (MVD) in NSCLC patients.Methods From January 2008 to December 2010,68 patients (48males and 20 females; age ranging from 36 to 84 years) with NSCLC underwent 18F-FLT PET/CT followed by surgery within two weeks.Tumor proliferation was evaluated in terms of Ki67 labeling index (LI) with SP.MVD was determined using anti-CD31 mAb (CD31-MVD),anti-CD34 mAb (CD34-MVD) and anti-CD105 mAb (CD105-MVD) for each resected tumor.Linear correlation analysis was used to analyze data.Results The mean values of CD31-MVD,CD34-MVD and CD105-MVD were 159.6,166.1,and 38.0 per view field,respectively.Tumor SUVmax was 4.1±2.9,and Ki67 LI was (37.0± 14.5) ％,both of which had significantly correlations with CD105-MVD (r=0.550,0.633 ; both P＜0.05),but there was no significant relationship between SUVmax and CD31-MVD,CD34-MVD (r=0.228,0.235; both P＞0.05).Conclusion 18F-FLT PET/CT imaging has a positive relationship with CD105-MVD of NSCLC,and it could reflect the ability of tumor angiogenesis.

Objective:To study the effect of portal vein occlusion on intestinal mucosal barrier in rats and the protection of ulinastatin to the injury,to present the experimental data for the clinical surgery.Methods:70 Sprague-Dawley rats were randomly divided into controlled group (n=10),operation group (n=30) and operation+medication group (n=30).The portal vein were occlused 40 min in the operation groups and operation+medication groups.2ml blood from portal vein,lymph nodes around appendix,1cm small intestine wall were taken for endotoxin levels,bacterial translocation and pathiology examinations in the all rats 280 mins after operation.The mocusal barrier and microscopic structure of intestine were observed.Results:Compared between the control group and the operation group,endotoxin levels,bacterial translocation rates rise greatly and gut structure change obviously in the latter.Compared between the operation group and operation+medication group,the former changes is also obvious.Conclusion:The occlusion of portal vein can leads the decrease of intestine mocusal barrier and the increase of its permeability.Ulinastatin has a good protective effect on the damages above.
