Objective A major component of flow cytometry data analysis involves gating , which is the process of identifying homogeneous groups of cells .As manual gating is error-prone, non-reproducible, nonstandardized, and time-consuming , we propose a time-efficient and accurate approach to automated analysis of flow cytometry data .Methods Unlike manual analysis that successively gates the data projected onto a two-dimensional filed, this approach, using the K-means clustering results , directly analyzed multidimensional flow cytometry data via a similar subpopulations-merged algorithm.In order to apply the K-means to analysis of flow cytometric data , kernel density estimation for selecting the initial number of clustering and k-d tree for optimizing efficiency were proposed .After K-means clustering , results closest to the true populations could be achieved via a two-segment line regression algorithm .Results The misclassification rate (MR) was 0.0736 and time was 2 s in Experiment One, but was 0.0805 and 1 s respectively in Experiment Two. Conclusion The approach we proposed is capable of a rapid and direct analysis of the multidimensional flow cytometry data with a lower misclassification rate compared to both nonprobabilistic and probabilistic clustering methods .

Burkitt lymphoma (BL) is an aggressive B-cell non-Hodgkin lymphoma which often occurs in children. The cure rate of BL is significantly increased with the wide application of short-duration and high-intensity immunochemotherapy, however, chemotherapy-related adverse reactions are still a big problem in adult patients and human immunodeficiency virus (HIV) positive patients. Meanwhile, the absence of effective immune targeting new drugs in patients with relapsed and refractory BL needs to be solved clinically. How to optimize the therapeutic regimen to reduce the chemotherapy-related adverse reactions and develop effective immune targeting new drugs is the hot spot in current research. This paper reviews the treatment progress of BL according to the 59th American Society of Hematology (ASH) Annual Meeting.

Objective:To investigate the clinical effect of using combined lumbar pelvis fixation device in the treatment of old vertical unstable fracture dislocation of posterior pelvic ring.Methods:Data of 7 patients with old vertical unstable fracture dislocation of posterior pelvic ring admitted and followed up from January 2017 to April 2020 were retrospectively analyzed, including 4 males and 3 females with an average age of 42.4 years old (range, 22-73 years old). There were 3 cases of traffic injury, 3 cases of falling injury and 1 case of tumble injury. According to Tile classification for pelvic fractures, there were 5 cases of type C1, 1 case of type C2 and 1 case of type C3. The average time from fracture to surgery was 5.4 weeks (range, 3-10 weeks). Among the 7 patients, 4 patients' posterior ring fractures were fixed by combined lumbar pelvic triangle fixation, and 3 patients' posterior ring fracture were fixed by combined lumbar pelvic fixation. 4 patients' anterior ring injury were not treated, 2 patients' anterior ring injury were treated by closed cannulated screw and internal fixation, and 1 patient's anterior ring injury was fixed by INFIX and cannulated screw. Every patient's operating time, intraoperative blood loss, length of incision and times of X-ray fluoroscopy were recorded. Pelvic X-ray and CT scan were taken postoperatively to observe the condition of reduction and screw position. Postoperative fracture reduction quality was assessed by Matta radiological criteria and Majeed criteria was used at the final follow-ups to evaluate the degree of functional recovery after pelvic fracture.Results:The average operating time of 7 patients was 143 min (range, 96-205 min); the intraoperative average blood loss was 579 ml (range, 300-1 650 ml); the average length of incisions was 12.9 cm (range, 9-15 cm) and the average time of X-ray fluoroscopy was 27 times (range, 15-52 times). Postoperative X-ray and CT scan showed that the displacements of the posterior rings were reset well and all the hollow screws were located accurately and firmly. Postoperative radiation quality was evaluated according to Matta radiological criteria, and there were 4 cases of excellent, 2 cases of good and 1 case of fair, with an excellent and good rate of 85.7% (6/7). Seven patients had good fracture union. The average followed up time for all 7 patients was 12 months (range, 6-16 months). At the last follow-up, imaging examination showed good reduction of the sacroiliac joint, and the reduction of anterior and posterior rings were not lost. The healing time was 14.2 weeks (range, 12-20 weeks). Majeed score: postoperative 4.90±6.64 points (range, 48-58 points), postoperative 3 months 71.40±7.32 points (range, 67-75 points), postoperative 6 months 84.90±8.14 points (range, 68-96 points), the difference was statistically significant ( F=0.614, P=0.004). Majeed score 6 months after operation showed that 5 cases were excellent, 1 case was good and 1 case was fair, and the excellent and good rate was 85.7% (6/7). Conclusion:Using combined lumbar pelvis fixation device in the treatment of old vertical unstable fracture dislocation of posterior pelvic ring has good reduction quality, high fixed strength and good postoperative effect.

Objective To investigate the clinical features of pulmonary lymphoma and to get a better understanding of this disease. Methods Clinical data of 253 lymphoma patients in the Department of Lymphoma and Hematology in Jilin Cancer Hospital from October 2014 to March 2017 were retrospectively analyzed. The patients were divided into 30 cases of pulmonary lymphoma (lung lymphoma group) and 223 cases of non-pulmonary lymphoma (the control group). Rate assay and latex turbidimetry was used to detect lactic dehydrogenase (LDH) and β2macroglobulin (β2-MG) respectively. The expressions of programmed death 1 (PD-1), programmed death ligand 1 (PD-L1) and cytotoxic T lymphocyte-associated antigen 4 (CTLA-4) in peripheral blood CD4 +CD8 +T lymphocytes were detected by using flow cytometry. The count and measurement data of both groups were compared by using χ 2test and t test respectively. Results The patients in pulmonary lymphoma group showed secondary lesions. The proportion of smoking people in pulmonary lymphoma group was higher than that in the control group [43.3 % (13/30) vs. 24.2 % (54/223), χ 2＝ 4.964, P＝ 0.026]. The proportion of the patients in Ⅲ-Ⅳ stage in pulmonary lymphoma group was higher than that in the control group [93.3 % (28/30) vs. 57.0 % (127/223), χ2＝ 14.750, P < 0.001]. The proportion of the patients with higher international prognostic index (IPI) score in pulmonary lymphoma group was higher than that in the control group (χ2＝ 21.888, P < 0.001). The proportion of the patients with increased expression of β2-MG in pulmonary lymphoma group was higher compared with the control group [66.7 % (20/30) vs. 50.2 % (112/223), χ2＝6.682, P ＝0.091]. The proportion of the patients with the increased LDH was higher compared with the control group [63.3 % (19/30) vs. 41.5 % (86/223)], and the difference was statistically significant (χ2＝ 6.682, P ＝ 0.010). Diffuse large B-cell lymphoma (DLBCL) was the common pathological type in pulmonary lymphoma group (15 cases), followed by Hodgkin lymphoma (7 cases); imaging showed single mass or nodular type, multiple masses or nodular type, bilateral pulmonary infiltration, pleural effusion were 36.7 % (11/30), 30.0 % (9/30), 63.3 % (19/30) and 36.7 % (11/30), respectively. There were no statistical differences in the protein expression of immune check points such as PD-1, PD-L1 and CTLA-4 in both groups (all P ＞ 0.05). Conclusions Pulmonary DLBCL should be considered a secondary disease, but not a primary lesion. Smoking history is a risk factor for lymphoma patients with pulmonary involvement. Pulmonary lymphoma is similar to other extra-nodal lymphoma with high IPI scores, advanced stage and elevated LDH.

Objective To investigate the significance of fibroblast growth factor 23 in metabolic bone disease of prematuriy.Methods 60 patients who had been treated in our hospital from March 2016 to March 2017 were included in this study.Blood biochemistry was examined two weeks after birth,and values of blood phosphorus, serum calcium and alkaline phosphatase were recorded. Serum levels of 25 hydroxyvitamin D3,parathyroid hormone and fibroblast growth factor 23 were detected two weeks after birth. 20 premature infants with metabolic bone disease were selected as a study group. 40 infants without metabolic bone disease were treated as a control group. Two weeks after treatment,the above indicators were measured and compared in the study group. Results Serum levels of 25 hydroxyvitamin D3,parathyroid hormone and fibroblast growth factor 23 were compared between the two groups 2 weeks after birth,the difference was statistically significant(P<0.05).Levels of serum parathyroid hormone and fibroblast growth factor 23 in the study group were not statistically significant after treat-ment(P > 0.05). Levels of 25 hydroxy vitamin D3 in the study group had statistically significant after treatment (P<0.05).Conclusions Early detection of fibroblast growth factor 23 can reflect metabolic bone disease in pre-term infants.It suggests that vitamin D should be adequately supplemented in early.
