The paper, using microscopical counting method, studies the relationship between the normal reference values of 38,061 samples of red blood cell count of presenile men and eight geographical factors in 297 units in China. It is found that the correlation of geographical factors and the normal reference value of red blood cell count of presenile men is quite significant （F=303.00, P=-0.000）. By using the method of stepwise regression analysis, one regression equation is inferred. It is concluded that if geographical data are obtained in a certain area, the normal reference value of red blood cell count of presenile men in this area can be reckoned by using the regression analysis. Furthermore, according to the geographical factors, China can be divided into eight regions： Northeast China Region, North China Region, Shanxi-Shaanxi-Irmer Mongolia Region, Middle and Lower Reaches of the Changjiang River Region, Southeast China Region, Northwest China Region, Southwest China Region and Qinghai-Tibet Plateau Region.展开更多

This study deals with count changes of particular blood cells accompanying the IAR, LAR and DYAR. Methods: In 63 patients developing 22 IAR, 26 LAR and 15 DYAR, the repeated allergen challenges were supplemented with recording of blood cell counts, Th1/Th2 ratio, leukotrines B4 (LTB4) and C4 (LTC4), eosinophil cationic protein (ECP), myeloperoxidase (MPO), and histamine in blood, and intracellular IFN-γ and IL-4 in peripheral blood mononuclear cells. Results: The IAR was accompanied by increased eosinophil and basophil counts, increased serum concentrations of histamine, LTC4 and ECP, decreased Th1/Th2 ratio in favour of Th2 cells, and increased intracellular IL-4. The LAR was associated with increased eosinophil and neutrophil counts, increased serum concentrations of LTC4 and LTB4, unchanged Th1/Th2 ratio, and increased intra-cellular IL-4. The DYAR was accompanied by increased total leukocyte, neutrophil, monocyte, lymphocyte and thrombocyte counts, increased serum concentrations of LTB4 and MPO, increased Th1/Th2 ratio in favour of Th1 cells, and increased intracellular IFN-γ. Conclusions: These results provide evidence for different involvement of particular blood cell types and different hypersensitivity mechanisms in IAR, LAR and DYAR. The monitoring of peripheral blood cell counts seems to be an useful supplementary parameter to the bronchial challenge with allergen.展开更多

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
