		                        			OBJECTIVE:
		                        			To evaluate the clinical characteristics, treatment and prognosis of systemic anaplastic large cell lymphoma(sALCL).
		                        		
		                        			METHODS:
		                        			The clinical data of 90 cases with sALCL treated in the Department of Hematology of the Affiliated Xijing Hospital of Air Force Medical University from November 2018 to October 2021 were retrospectively analyzed. The clinical features, treatment and prognosis were summarized and the prognostic factors were investigated.
		                        		
		                        			RESULTS:
		                        			There were 58 males and 32 females, with a median age of 32 (12-73) years old. 69 (76.7%) patients had Ann Arbor stage Ⅲ-Ⅳ disease and half of the patients had extranodal infiltration. The median age was 27(12-72) years of the 60 ALK+ patients while 53(15-73) years of the 30 ALK- patients, and it was significantly different in the age of onset between the two group(P<0.01). 88 patients received first line chemotherapy, and 50(568%) cases achieved complete remission(CR). IPI score≥3 was an independent risk factor for CR. The median progressive free survival(PFS) and overall survival(OS) of the patients were not reached. Multivariate analysis showed that no achievement of CR after first-line therapy was a significant prognostic factor influencing PFS and OS.
		                        		
		                        			CONCLUSION
		                        			sALCL mainly occurs in males and most patients were in advanced stage. Half of the patients had extranodal involvement. The CR rate after first-line chemotherapy was 568%, and IPI score≥3 was a significant prognostic factor for CR. No achievement of CR after first-line therapy is poorly prognostic for PFS and OS.

		                        			OBJECTIVE:
		                        			To observe the clinical characteristics, treatment and prognosis of intestinal acute graft-versus-host disease (aGVHD) after allogeneic hematopoietic stem cell transplantation (allo-HSCT) in children and futher evaluate the occurring risk factors.
		                        		
		                        			METHODS:
		                        			The clinical data of 136 patients undergoing allo-HSCT in Wuhan Children's Hospital Affiliated to Tongji Medical College from August 2016 to August 2020 were retrospectively analyzed, clinical characteristics of children with intestinal aGVHD were observed. The risk factors of intestinal aGVHD were assessed by logistic regression while cumulative survival were analyzed by Kaplan-Meier method.
		                        		
		                        			RESULTS:
		                        			Among 136 patients intestinal aGVHD occurred in 24 (17.6%) cases, with 4 cases of grade II, 20 cases of grade III-IV, and the median occurrence time was 28(10-63) days. The clinical manifestations were diarrhea with intermittent abdominal pain, 17 cases with nausea and vomiting, 11 cases with fresh bloody stool, and 8 cases with skin rash before intestinal aGVHD. The average time for treatment was 33(11-100) days. 18 cases received electronic colonoscopy and histopathology examination. 20 out of 24 cases achieved remission after treatment, and the total effective rate was 83.3%. Finally, 9 out of 24 cases died during the follow-up time. Survival analysis showed that the cumulative survival rate of patients with intestinal aGVHD (15/24, 62.5%) were significantly lower than those without intestinal aGVHD (101/112, 90.2%) (Log-rank test, P=0.001). Univariate analysis showed that recipient age, sex, primary disease, donor age, donor sex, donor-recipient blood type, conditioning regimen, prophylaxis of GVHD, dosage of ATG, engraft time of blood platelet and neutrophils, and number of MNC/CD34+ were not risk factors for intestinal aGVHD (P>0.05). Only the type of HSCT (χ2=16.020, P=0.001) and matched degree of HLA (χ2=15.502, P=0.001) had statistical significance with intestinal aGVHD (P<0.05). Multivariate analysis showed that only HLA-mismatched unrelated donor was the risk factor for intestinal aGVHD for children (P=0.014,OR=16,95%CI 1.735-147.543).
		                        		
		                        			CONCLUSION
		                        			Intestinal aGVHD is a risk factor for cumulative survial of patients who received allo-HSCT in children and HLA-mismatched unrelated donor is its independent risk factor.

		                        			Objective:To explore systematic implementation of World Health Organization Family International Classifications (WHO-FICs) in the field of rehabilitation: the theoretical and policy framework at macro level, governance and management mechanism at meso level, and implementation modules at micro levels, respectively. Methods:The policy and theoretical framework of rehabilitation development was discussed based on the international rehabilitation policy documents of WHO, mainly as World Report on Disability, Global Action Plan on Disability and Rehabilitation in Health Service System. Protocol and roadmap of systematic implementation of WHO-FICs, including International Classification of Diseases (ICD-11), International Classification of Functioning, Disability and Health (ICF), and International Classification of Health Intervention (ICHIβ-2) was proposed. Results:With the use of WHO-FICs, the theoretical and policy framework of rehabilitation was constructed, and the contents and principles of modern rehabilitation services were clarified at macro-level. Rehabilitation is an important part of health service, there are six building blocks: i.e. leadership and governance, financing, human resources for health, service providing, medical technology and health information system. It proposed to use knowledge management system of WHO-FICs, including the classification, nomenclature, definitions, descriptions, terminology and coding systems, to standardize rehabilitation evaluation and statistics. The management and governance system of rehabilitation should be implemented using WHO-FICs. Rehabilitation services are based on the bio-psycho-social model and implemented the principles of people-centered and functioning-oriented. The systematic implementation of WHO-FICs in rehabilitation abide by the model of "Evaluation (ICHI)-Evaluation, Description, Classification and Coding of Functioning (ICF)-Disease Classification, Diagnosis and Coding (ICD)-Rehabilitation Intervention (ICHI)", and with the standardized process of "Evaluation (Functioning and unmet needs)-Diagnose (Disease and Functioning)-Planning of Rehabilitation-Intervention-Evaluation of Outcome". The mic-modules of implementation of WHO-FICs in rehabilitation had been constructed. There were 28 categories of diseases, 7 categories of functioning and 6 categories of rehabilitation interventions in rehabilitation proposed by International Society of Physical and Rehabilitation Medicine. According to ICD-11 and ICF, it proposed to use WHO Disability Assessment Schedule 2.0 (WHODAS 2.0), Brief Model Disability Survey (MDS-B) and VB40 Generic Functioning Domains (VB40), and the ICF core-sets in evaluation of functioning and rehabilitation outcome. The implementation of WHO-FICs in management of medical records and reporting realized the standardized management of medical record, encoding of diseases, functioning and intervention, reporting of performance, and provided tools for billing, reimbursement and payment management of rehabilitation. It proposed to develop WHO-FICs based clinical data sets and big data to implement functioning-related Diagnosis Related Groups and case-mix statistics. Conclusion:With the systematic implementation of WHO-FICs in rehabilitation, the policy and theoretical framework at macro level had been developed. The mechanism of management and governance at meso level had been explored. The application modules and approaches at micro level had been established. A scientific and effective overall solution had been proposed to enhance the scientific, standardized, refined and informatization level, strengthen the level and governance capacity, and improve the quality, safety and the coverage of rehabilitation services.

		                        			OBJECTIVE:
		                        			To explore the feasibility of RhCcEe blood group antigen mixed visual field identification in patients with regular blood transfusion, to follow up and evaluate the efficacy of matched transfusion and its clinical significance.
		                        		
		                        			METHODS:
		                        			RhCcEe genotyping for 142 patients with regular transfusion in our hospital was carried out by PCR-SSP method. According to the results of genotyping, 48 patients voluntarily selected the continuous transfusion of RhCcEe matched red blood cells, 46 patients received random blood transfusion (RhCcEe mismatched transfusion), 42 patients received partial RhCcEe matched transfusion (unable to provide fully matched RhCcEe donors each time), and 6 patients' blood transfusion data were lost. After 3-6 months of the RhCcEe matched transfusion, all patients were tested by RhCcEe microcolumn gel card and compared with the results before RhCcEe matched transfusion. The positive rates of alloantibodies, DAT and the percentage of red blood cell invalid transfusion were followed up and evaluated for the above-mentsioned 3 types of regular transfusion patients in the past 5 years.
		                        		
		                        			RESULTS:
		                        			Out of the 48 patients who underwent conti-nuous RhCcEe matched transfusion, only 1 case showed stratification, the remaining 47 cases had clear gel card results without stratification, suggesting that PCR-SSP genotyping was feasible. In addition, another 42 patients who could not receive RhCcEe matched transfusion each time and 46 patients with random blood transfusion were found to have a mixed vision phenomenon again. but the results was still difficult to confirm the results. For the transfusion results in the past 5 years, follow-up analysis showed that there were 1 case alloantibody (anti-Jka) (1/48) , 1 case of DAT positive (1/48) and 2 cases of invalid transfusion (2/48) in the RhCcEe matched transfusion group; 7 cases of alloantibodies (3 anti-E, 1 anti-E+anti-c, 1 anti-C, 1 anti-M, 1 anti-Fya) (7/46), 6 case of DAT positive (6/46) and 9 case of invalid transfusion (9/46) in the random transfusion group; 6 cases of alloantibodies (1 anti-E, 1 anti-E+autoantibody, 1 anti-C, 1 anti-c, 1 anti-M and 1 other antibody) (6/42) and 7 case of DAT positive (7/42) and 8 case of invalid transfusion (8/42) in the partial RhCcEe matched transfusion group. The statistical analysis showed that the positive rate of alloantibodies and the invalid infusion rate of RBC in each group were significant differences between RhCcEe matched transfusion group and the random transfusion group as well as betwen Rhce fe matched transfusion group and the partial matched transfusion group(P<0.05), but there was no statistical difference between the random transfusion group and the partial matched transfusion group(P>0.05).
		                        		
		                        			CONCLUSION
		                        			PCR-SSP genotyping technique can be used to detect RhCcEe mixed vision in patients with regular blood transfusion. Continuous RhCcEe matched transfusion can effectively prevent the occurrence of alloimmunization, and improve the clinical transfusion efficacy and safety of the patients with regular blood transfusion, which has very important clinical significance.

OBJECTIVETo investigate the expression of retinol-binding protein (RBP) in patients with acute myeloid leukemia (AML) and its related factors.
METHODSThe clinical data of 123 patients with AML from October 2012 to February 2016 and 100 healthy controls were collected and the correlation of RBP expression level with sex, French-American-British (FAB) subtypes, molecular mutations, peripheral white blood cells and long-term outcomes was analyzed.
RESULTSCompared with AML patients, the RBP expression level was significantly higher in healthy controls (61.02±34.97 vs 34.44±14.08 mg/L)(u=8.658, P<0.01). Patients with M3 showed higher RBP level (40.74±15.79 mg/L) compared with that of M4 (28.40±13.64 mg/L)(P<0.01) and M5 (31.97±15.31 mg/L)(P<0.05). Negative correlation was observed for RBP and white blood cells in patients with AML (r=-0.352, P<0.001), which was more remarkable in patients with M4 (r=-0.563, P<0.01) and M5 (r=-0.423, P<0.01). AML patients achieved complete remission (CR) (48.64±9.24 mg/L) showed higher RBP level than that before treatment (u=4.876, P<0.01), but lower than healthy controls (u=2.106,P<0.05). After CR, patients with M3 showed higher RBP level than that of non-M3 patients (54.91±5.25 mg/L vs 41.36±7.33 mg/L)(t=8.777,P<0.01).
CONCLUSIONDetecting RBP expression may provide some useful information for urderstanding the pathophysiology and improving the treatment of patients with AML.

OBJECTIVETo compare the differences between weak ABO antigen patients and normal ABO antigen patients with acute leukemia, and to explore the clinical significance of weak ABO antigen in acute leukemia.
METHODSThe ABO blood group was detected in 110 newly diagnosed acute leukemia patients(including 68 cases of AML and 42 cases of ALL) and 68 normal controls. Then the leukemia subtype, age, sex, laboratory test, risk status of leukemia patients, and DNA methylation of ABO promoter were compared between patients with weak and normal ABO antigen.
RESULTSThe weak ABO antigen was found in patients with newly diagnosed acute leukemia, and was not found in ALL patients or normal group. No statistical differences were found in the distribution of ABO blood group, age, hepatosplenomegaly, lymphadenovarix, plt, precursor cell clusters derived from bone marrow, immunopheno-typing, LDH level, and risk status between AL patients of weak and normal ABO antigen groups (P>0.05). Compared with patients in normal ABO antigen group, the pateins in weak ABO antigen group had higher percentage of male(77.8% vs 30%), lower WBC(32.26×10/L vs 82.69×10/L) and Hb level(64.00 g/L vs 85.94 g/L) and higher DNA methylation level (18.91% vs 10.76%) (P<0.05).
CONCLUSIONThe cases of weak ABO antigen frequently appear in the male AML patients, the DNA methylation level of ABO gene promoter in patients with weak ABO antigen is significantly higher than that in patients with normal ABO antigen.
9.Expression of miR-155 in Acute Myeloid Leukemia and Its Clinical Significance.
Journal of Experimental Hematology 2016;24(4):980-984
OBJECTIVETo investigate the expression of microRNA-155(miR-155) in bone marrow mononuclear cells (BMMNC) of the patients with acute myeloid leukemia(AML) and its clinical significance.
METHODSReal-time quantitative PCR (qPCR) was used to detect the expression level of miR-155 in bone marrow mononuclear cells from 80 cases of AML and 11 cases of negative control patients.
RESULTSCompared with the negative control group ,the expressions of miR-155 in initial diagnosis group and remission group both increased (P<0.01), that in the initial treatment group was significantly higher than the remission group (P<0.05). The expression level of miR-155 did not significantly correlate with the clinical features of patients. Between different cytogenetic groups in AML patients, miR-155 expression levels in the moderate prognostic group and poor prognositic group were significantly higher as compared with the favorable prognosis group P<0.05, P<0.05), but there was no significant difference between poor and moderate progrestic groups(P>0.05). The results of tracking the situation after induction therapy of newly diagnozed AML patients showed that the remission rate of initial induction in miRNA155 high expression group and low expression group were 59.09% and 87.5% (X(2) =4.8, P<0.05), and the expression level of miR-155 in initial diagnosis of patients without complete remission after chemotherapy was significantly higher than that in patients with complete remission after chemotherapy (P= 0.042).
CONCLUSIONThe expression of miR-155 in AML patients is high and reduced the rate of complete remission. The high expression of miR-155 is an poor prognostic factor for patients with AML.

OBJECTIVETo investigate the influence of CD117 expression on response of multiple myeloma patients to chemo-therapy.
METHODSA total of 65 cases of newly diagnosed multiple myeloma in our hospital from 2011 to 2013 were enrolled in this study. Cytogenetic abnormalities and immunophenotype were detected by using fluorescence in situ hybridization and flow cytometry before chemotherapy. The therapeutic efficacy of patients was evaluated after 4 cycles of PAD or TAD regimen.
RESULTSThe positive rates of 1q21 amplification, RB1: 13q14 deletion, D13S319: 13q14.3 deletion, IgH: 14q32 rearrangement and p53: 17p13 deletion were 32.2%, 40%, 40%, 20% and 3.1% respectively; the positive rates of CD38, CD138, CD56, CD117, CD20 were respectively 100%, 100%, 60%, 20%, 10.8%; the positive rates of CD19 and CD10 were 4.6% and 4.6% respectively; the positive CD22, CD7, CD5, CD103 did not found in any patients. The therapeutic efficacy of CD117⁻ patients was better than that of CD117⁺ patients (P < 0.05), there was no correlation of the remaining indicators with efficacy; the proportion of CD117⁺ patients with β2-microglobulin ≥ 5.5 mg/L was significantly higher than that of CD117⁻ patients (P < 0.05); the rest of baseline data had no significant difference (P > 0.05).
CONCLUSIONCD117 can be used as an indicator for evaluating efficacy of patients with newly diagnosed multiple myeloma.
