A small proportion of cases of chronic granuloid leukemia is associated with an extraordinary concentration of leukocytes in the blood. As a result of the hyperleukocytic syndrome, these cases present special problems and complication that may seriously affect on patients’ life and the quality of life to the physicians. Leukapheresis is an effective method of therapy in these cases which can reverse the hyperleukocytic syndrome rapidly and decrease the tumor cell mass so as to minimize the extent of chemotherapeutic-induced cytolysis and the cytolysis- induced complications.

The count and recognition of white blood cells in blood smear images play an important role in the diagnosis of blood diseases including leukemia. Traditional manual test results are easily disturbed by many factors. It is necessary to develop an automatic leukocyte analysis system to provide doctors with auxiliary diagnosis, and blood leukocyte segmentation is the basis of automatic analysis. In this paper, we improved the U-Net model and proposed a segmentation algorithm of leukocyte image based on dual path and atrous spatial pyramid pooling. Firstly, the dual path network was introduced into the feature encoder to extract multi-scale leukocyte features, and the atrous spatial pyramid pooling was used to enhance the feature extraction ability of the network. Then the feature decoder composed of convolution and deconvolution was used to restore the segmented target to the original image size to realize the pixel level segmentation of blood leukocytes. Finally, qualitative and quantitative experiments were carried out on three leukocyte data sets to verify the effectiveness of the algorithm. The results showed that compared with other representative algorithms, the proposed blood leukocyte segmentation algorithm had better segmentation results, and the mIoU value could reach more than 0.97. It is hoped that the method could be conducive to the automatic auxiliary diagnosis of blood diseases in the future.

A study was conducted on 28 burning sepsis patients treated at the National Institute of Burn. Results showed that their capacity of bacteriophage and of EA rosette formation of polynuclear neutrophil white blood cells was reduced in comparing with healthy patients and with other no burn sepsis patients, as well as burning no sepsis patients. Their white blood cells function restored gradually with the improvement of the condition. Thus the capacity of bacteriophage and EA rosette formation have reflected the state of burning conditions, and their monitoring can help the evaluation and prognosis

By using the test of leukocyte concentration in peripheral blood of some patients with myelodisplastic syndrome (MDS) hypoplasia/aphasia, the authors had drawn out some following: (1) The test of leukocyte concentration is valuable in the detection of immature cells in peripheral blood of patients with MDS and hypoplasia/aphasia. (2) In hypoplasia/aphasia: 28.8% of the patients have about 3.03% myeloblast and 39.7% have about 1.07% erythroblast in peripheral blood. (3) In MDS: 46.2% of the patients have 1.15% myeloblast and 61.5% of them have 1.92% erythroblast in peripheral blood.
