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.

Objective To establish a practical and effective predictive model for predicting carotid plaque/thickened intima,and to provide a novel perspective for stroke screening.Methods A retrospective analysis of the community screening data collected from September 2012 to March 2013 was performed.The data of blood pressure,serum lipid profile and fasting blood glucose and ultrasonographic checks of carotid artery were documented.One thousand subjects were randomly sampled from totally 14 226 individuals and divided into 2 groups according to the presence of carotid plaque/thickened intima.Analysis of relevant data of subjects with Logistic regression were performed.Predictive model was established according to the odds ratio for each risk factor and evaluated by C statistics.Results In the randomly sampled 1000 subjects,164 ones were found to be with carotid plaque/thickened intima.The mean age was (60.23 ± 10.09) years old,110 (67.1％) were male.Smoker,hypertension,angina pectoris,diabetes and hyperlipidemia were seen more often in the subjects with carotid plaque/thickened intima.Logistic regression analysis showed the independent risk factors for carotid plaque/thickened intima included advanced age (OR =1.15,95％ CI:1.12-1.84,P＜0.01),male (OR=3.97,95％CI:2.49-6.33,P＜0.01),smoking (OR=1.80,95％CI:1.24-2.56,P =0.002),diabetes (OR =1.80,95％ CI:1.15-2.98,P =0.012),hypertension (OR =2.82,95％ CI:1.15-2.98,P ＜ 0.01),high total cholesterol level (OR =1.63,95％ CI:1.31-2.02,P ＜ 0.01) and high LDL-C (low density lipoprotein-cholesterol) level (OR =1.70,95 ％ CI:1.35-2.14,P ＜ 0.01).The advanced age was found to be the strongest predictive factor in this model.The C statistics of this model is 0.804,which overweighs other models previously reported.The optimal cutoff point for prediction was 3.5,with a sensitivity of 0.713 and a specificity of 0.757.Conclusion An practical and effective model for predicting carotid plaque/thickened intima established from sampling data of community residents is favorable for both stroke screening and primary stroke prevention.

BACKGROUND:Pathological examination and MRI have been widely used in clinic, but their combination is rarely reported in discrimination of early spine infections.
OBJECTIVE:To determine the accuracy of pathology and MRI for discrimination between early pyogenic spondylitis and brucella spondylitis.
METHODS:Twenty-two patients with pyogenic spondylitis and 20 patients with brucella spondylitis who had CT-guided percutaneous biopsy and MRI of the spine were retrospectively reviewed. Pathological observations included structure and activity of bone lesions, tissue cells and their main components;MRI observations included signal and sign changes at lesion sites. Statistical analysis was performed with the chi-square test.
RESULTS AND CONCLUSION:The patients with pyogenic spondylitis had a significantly higher incidence of pathological and MRI findings as fol ows (P<0.05):neutrophil infiltration;intervertebral disc abnormal signal, location of vertebral body lesions anterior+posterior, obviously shape change in the vertebral body, paraspinal abnormal signal, presence of intraosseous or paraspinal abscess. Pathological and MRI examination was accurate for early differentiation of pyogenic spondylitis from brucella spondylitis.

BACKGROUND:The reasons for spinal imbalance include spinal deformity, spinal degenerative disease osteoporotic vertebral compression fractures. We believe that the power factor (back muscle) plays a key role in spinal sagittal imbalance. OBJECTIVE:To analyze the reasons for spinal sagittal imbalance by observing clinical manifestations and therapeutic outcomes in patients with osteoporotic vertebral compression fractures. METHODS:A total of 41 patients with osteoporotic compression fractures combined with spinal sagittal imbalance were retrospectively analyzed from January 2012 to May 2013. Al patients were subjected to percutaneous bal oon vertebroplasty under local anesthesia. Before treatment, they received bone density, standing ful-spine lateral X-ray, CT and MR imaging with injured vertebrae as the center. Using standing ful-spine radiographs, the height of anterior border of the injured vertebrae, Cobb angle of kyphosis and improved angle, wedging angle of the injured vertebrae and improved angle were measured. The patients underwent weight loading test and walking test. Preoperative and postoperative data were compared. RESULTS AND CONCLUSION:The patients affected spinal sagittal imbalance symptoms, so the walking distance was significantly shorter than that postoperatively (P<0.05). Moreover, the time of weight loading test was significantly shorter than that postoperatively (P<0.05). In standing ful-spine radiographs, the average difference of Cobb angle was (10.01±0.76)°. The mean difference of vertebral wedging improvement was (4.84±0.40)° (P<0.05). Al patients were fol owed up. Low back pain and sagittal imbalance symptoms were relieved. No severe complications appeared after percutaneous bal oon vertebroplasty. Results indicated that patients with osteoporosis compression fractures can affect the symptoms of spinal sagittal imbalance, which is not only induced by wedging of the injured vertebra. In addition, after percutaneous bal oon vertebroplasty, imbalance symptoms are apparently improved, suggesting that back pain after spinal fracture limits back muscle strength and is an important cause for spinal sagittal imbalance.
