During this time, 3296 patients underwent upper endoscopy. In total, 50 male(69.2 ± 13.2 years) and 26 female(72.3 ± 10.2 years) patients were assessed. Patients were divided into two groups based on BUN levels: higher than the normal limit(21.0 mg/d L)(H) and lower thanthe normal limit(L). One-way analysis of variance was performed to reveal differences in the variables between the H and L groups. Fisher's exact test was used to compare the percentage of patients with gastric ulcer or gastric cancer in the H and L groups.RESULTS: White blood cell count was higher in the H group than in the L group(P = 0.0047). Hemoglobin level was lower in the H group than in the L group(P = 0.0307). Glycated hemoglobin was higher in the H group than in the L group(P = 0.0264). The percentage of patients with gastric ulcer was higher in the H group(P = 0.0002). The H group contained no patients with gastric cancer.CONCLUSION: Patients with BUN ≥ 21 mg/d L might have more severe upper gastrointestinal bleeding.展开更多

However, this last step is time consuming and requires experienced personnel. We evaluated the clinical efficiency of using flow cytometry （FCM） employing a six-antibody/five-color reagent for verifying automated WBC differentials. Methods A total of 56 apparently healthy samples were assessed using a five-color flow cytometer to verify the normal reference ranges of WBC differentials. WBC differentials of 622 samples were also determined using both a cell counter and FCM. These results were then confirmed using manual microscopic methods. Results The probabilities for all of the parameters of WBC differentials exceeded the corresponding normal reference ranges by no more than 7.5%. The resulting WBC differentials were well correlated between FCM and the cell counter （r 〉0.88, P 〈0.001）, except in the case of basophils. Neutrophils, lymphocytes, and eosinophils were well correlated between FCM and standard microscopic cytology assessment （r 〉0.80, P 〈0.001）. The sensitivities of FCM for identification of immature granulocytes and blast cells （72.03% and 22.22%, respectively） were higher than those of the cell counter method （44.92% and 11.11%, respectively）. The specificities of FCM were all above 85%, substantially better than those of the cell counter method. Conclusion These five-color FCM assays could be applied to accurately verify abnormal results of automated assessment of WBC differentials.展开更多
