Autologous blood donation is an important strategy of blood conservation. The Administrative Measures for the Clinical Use of Blood in Medical Institutions (Order No. 85 of the National Health Commission) requires medical institutions to promote the implementation of autologous blood donation actively. The clinical practice guidelines for patient blood management also recommend the proactive use of autologous blood donation to reduce the reliance on allogeneic blood. Preoperative autologous blood donation (PABD) is one of the autologous blood donation with wide range of indications, easy to operate, and can effectively reduce the transfusion of allogeneic blood. However, the performance of PABD in China is unsatisfactory due to various factors such as the patient composition of medical institutions, the implementation of outpatient department of blood transfusion, the level of attention paid to this issue, and the fact that traditional PABD do not meet clinical requirements. Therefore, improving the PABD model and exploring new PABD technology, as well as promoting their clinical application, are critical measures to meet the development requirements of patient blood management and to alleviate the shortage of blood supply. This article summarizes the improvements in the PABD model, and a novel PABD technology of PABD—preoperative deep apheresis of autologous red blood cells and/or platelets (deep apheresis autologous blood storage technology), and the current situation of clinical application of PABD to provide paradigm for clinical transfusion.

Objective:To investigate the associated factors of depressive symptoms among patients with neo-plasms.Methods:Nationwide(excluding Hong Kong,Macao,and Taiwan),30 505 residents were selected by a combination of stratified sampling and quota sampling according to the proportion of the seventh national population census.Patient Health Questionnaire-9(PHQ-9),General Anxiety Disorder-7(GAD-7),self-made questionnaire,and simplified perceived social support scale used to evaluate depressive symptoms,anxiety symptoms,behaviors,and perceived social support among patients with neoplasms.Results:Totally 359(1.2％)patients with self-repor-ted clinically diagnosed neoplasms were included,of which 151(42.1％)patients with malignant neoplasms and 208(57.9％)patients with benign neoplasms.The detection rate of depressive symptoms in patients with neo-plasms was 76.6％.Less than three days of walking for more than 10 minutes per day in the past week(OR=6.63),4-6 days of walking for more than 10 minutes per day in the past week(OR=5.00),the low(OR=4.80)or medium(OR=3.06)overall sleep quality,the lower perceived friend support(OR=4.66),and anxiety symp-toms(OR=1.74)among patients with neoplasms were risk factors for depressive symptoms.Conclusion:Patients with neoplasms generally might be at a high risk of depressive symptoms,especially for those patients with less ex-ercise,poor sleep quality,and low perceived social support.

Objectives:To investigate the diagnostic value of whole blood quantitative PCR for DNA load of Epstein-Barr virus (EBV) in post-transplant lymphoproliferative disease (PTLD) after allogeneic hematopoietic stem cell transplantation (allo-HSCT) .Methods:A total of 694 patients with hematologic diseases who underwent allo-HSCT at the Hematology Department of Peking University First Hospital from April 2004 to April 2019 were included, and their data were retrospectively analyzed.Results:①Among the 694 cases, 29 cases (22 males and 7 females, with a median age of 22 (1-52) years) developed PTLD after allo-HSCT with a cumulative incidence of 4.2% and a median onset time of 2.1 (0.8-20.6) months. ② Univariate analysis showed that age<30 years, diagnosis with aplastic anemia, human leukocyte antigen (HLA) mismatch, use of antithymocyte globulin (ATG) in preconditioning regimens, and EBV reactivation were the risk factors for the occurrence of PTLD. Multivariate analysis showed that EBV reactivation was an independent risk factor for the occurrence of PTLD. ③Further analysis of EBV reactivation cases showed that the peak value of EBV-DNA load was significantly higher in the PTLD group than that in the non-PTLD group ( P<0.001) and the incidence of PTLD increased with the increase of EBV-DNA load. Receiver operating characteristic (ROC) curve analysis indicated that PTLD was more likely to be diagnosed when the EBV-DNA load was >1.19×10 6 copies/ml (sensitivity 0.800 and specificity 0.768) . ④All patients with PTLD received rituximab-based treatment, with an overall response rate of 86.2% and an overall survival rate of 54.3%. Conclusion:The PTLD occurrence after allo-HSCT is highly correlated with EBV reactivation, and the higher the EBV-DNA load, the greater the risk of PTLD occurrence. The dynamic monitoring of EBV-DNA load plays an important role in predicting PTLD occurrence.

Objective: To explore the efficacy and prognostic factors of hematopoietic stem cell transplantation (HSCT) for the treatment of patients with anaplastic large cell lymphoma (ALCL) . Methods: The clinical records of 33 ALCL patients after HSCT were collected and analyzed retrospectively to evaluate the rates of overall survival (OS) and recurrence after autologous (auto-HSCT) and allogeneic HSCT (allo-HSCT) and the factors influencing prognosis. Results: The median-age of this cohort of 33 ALCL cases at diagnosis was 31 (12-57) years old with a male/female ratio of 23/10, 24 cases (72.7%) were ALK⁺ and 9 ones (27.3%) ALK^-. Of them, 25 patients (19 ALK⁺ and 6 ALK^-) underwent auto-HSCT and 8 cases (5 ALK⁺ and 3ALK^-) allo-HSCT with a median follow-up of 18.7 (4.0-150.0) months. Disease states before HSCT were as follows: only 6 patients achieved CR status and received auto-HSCT, 16 patients achieved PR (14 cases by auto-HSCT and 2 ones allo-HSCT) , the rest 11 cases were refractory/relapse (5 cases by auto-HSCT and 6 ones allo-HSCT) . There were 7 cases died of disease progression (5 after auto-HSCT and 2 allo-HSCT) and 5 cases treatment-related mortality (TRM) (2 after auto-HSCT and 3 allo-HSCT) , TRM of two groups were 8.0% and 37.5%, respectively. Both the median progression-free survival (PFS) and OS were 15 months after auto-HSCT, the median PFS and OS after allo-HSCT were 3.7 (1.0-90.0) and 4.6 (1.0-90.0) months, respectively. There was no statistically significant difference in terms of survival curves between the two groups (OS and PFS, P=0.247 and P=0.317) . The 2-year OS rates in auto-HSCT and allo-HSCT groups were 72% and 50%, respectively. The 5-year OS rates in auto-HSCT and allo-HSCT groups were 36% and 25%, respectively. Conclusion ALCL treated by chemotherapy produced high rates of overall and complete responses. Chemotherapy followed by auto-HSCT remained to be good choice for patients with poor prognostic factors. High-risk patients should be considered more beneficial from allo-HSCT.

Objective To evaluate the performance of hook effect of five immunoturbidimetric kits for the detection of specific proteins on biochemical analyzers.Methods Five immunoturbidimetric kits with higher market share that came from Beijing BSBE (A), Sichuan maccura (B), Shenzhen Mindray (C), Ningbo Medical System (D) and Beijing Leadman (E) were used to determine six specific proteins.A series of concentration gradient samples were prepared and tested to compare the performance of hook effect from different manufactures′kits when the analytical measurement ranges were known.Results In the five kits, the upper limits of the safe range of antigen excess about ASO, hs-CRP andβ2-MG were relatively higher in B and C.No hook effect occurred at the approximate concentration of 10 000IU/mL, 1 000mg/L and 226mg/L respectively.The highest upper limits for CysC were C and E kits, and both were greater than 112mg/L.The upper limits of the safety range for other manufacturers were more than 700mg/L about RBP except for D.The maximum upper limit of mALB was D.Hook effect did not appear at the concentration of 43 560mg/L approximately.Conclusion Different manufactures′immunoturbidimetric kits have different hook effect performance.The laboratories should verify the hook effect performance before using the kits, and select the most suitable kit to prevent hook effect.

Objective: To evaluate clinical outcomes of autologous (auto-HSCT) and allogeneic hematopoietic stem cell transplantation (allo-HSCT) for angioimmunoblastic T-cell lymphoma (AITL) . Methods: From June 2007 to June 2017, clinical data of AITL patients who underwent HSCT in eight hospitals were assessed retrospectively. Results: Of 19 patients, 13 male and 6 female with a median age of 50 (32-60) years old, 12 auto-HSCT and 7 allo-HSCT recipients were enrolled in this study, all donors were HLA-identical siblings. Two of allo-HSCT recipients were relapsed auto-HSCT ones. There were 5 patients (5/12) in complete response (CR) status and 7 (7/12) in partial remission (PR) status before transplantation in auto-HSCT group, and 2 (2/7) in PR status and 3 (3/7) in progression disease (PD) status before transplantation in allo-HSCT group. The median follow-up for the surviving patients was 46.5 months (range, 1-100 months) for the whole series, two patients lost in auto-HSCT group. Three patients developed acute graft-versus-host disease (aGVHD) and 5 chronic graft-versus-host disease (cGVHD) after allo-HSCT. Three patients died of primary disease and 1bleeding in auto-HSCT group. One patient died of primary disease and 2 transplantation-related mortality in allo-HSCT group. The 3-year cumulative overall survival (OS) were 56% (95%CI 32%-100%) and 57% (95%CI 30%-100%) for auto-HSCT and allo-HSCT, respectively (P=0.979) . The 3-year cumulative progression-free survival (PFS) were 34% (95%CI 14%-85%) and 57% (95%CI 30%-100%) for auto-HSCT and allo-HSCT, respectively (P=0.451) . Conclusion Both auto-HSCT and allo-HSCT were optimal choices for AITL. In clinical practice, which HSCT was better for AITL patients should be based on comprehensive factors including sensitivity to chemotherapy, risk stratification and disease status at transplantation.

Objective: To evaluate the feasibility and potential value of comprehensive geriatric assessment (CGA) in elderly (≥60 years) patients with newly diagnosed acute myeloid leukemia (AML) in China. Methods: The CGA results of 83 newly diagnosed AML (non-APL) patients from 16 hospitals in Beijing and Tianjin between March 2016 and December 2017 were prospectively collected and analyzed. The clinical data, treatment and follow-up information were also collected. Results: Of 83 newly diagnosed elderly AML patients, 81 patients (97.6%) completed all designated CGA assessment. The median number of impaired scales of the CGA assessment in the studied population was 2(0-6). Sixteen patients (19.3%) showed no impairments according to the geriatric assessment scales implem ented by this study. The distributions of impaired scales were as follows: impairment in ADL, 55.4%; IADL impairment, 42.2%; MNA-SF impairment, 48.2%; cognitive impairment, 15.7%; GDS impairment, 31.7%; HCT-CI impairment, 19.5%, respectively. In patients with "good" ECOG (n=46), the proportion of impairment for each CGA scale ranged from 6.5% to 37.0% and 32 patients (68.9%) had at least one impaired CGA scale. Survival analysis showed that the number of impaired scales of the CGA was significantly correlated with median overall survival (P=0.050). Conclusions CGA was a tool with feasibility for the comprehensive evaluation in elderly AML patients in China. Combined with age and ECOG, CGA may be more comprehensive in assessing patients’ physical condition.

Objectives To detect the level of soluble programmed death 1 (sPD-1) and soluble programmed death ligand 1 (sPD-L1) in serum and urine of children with primary nephrotic syndrome (PNS),and explore its clinical significance.Methods From July 2017 to November 2017,children with PNS admitted to the Children's Hospital Affiliated to Soochow University were divided into onset group (36 cases) and remission group (33 cases).Thirty healthy children who underwent medical examination for enrollment,undersize or overweight in the outpatient department of pediatric health care and inpatient department of Endocrinology were selected as healthy control group.Serum and urine samples were collected,in which the levels of sPD-1 and sPD-L1 were detected by enzyme-linked immunosorbent assay (ELISA).The correlation between serum and urine sPD-1,sPD-L1 levels and lymphocyte subsets,urinary protein were analyzed by Pearson and Spearman correlation analysis.Results The level of sPD-1 in serum was lower in remission group than those in healthy controlgroup [1.60(0.48,8.15) ng/ml vs 7.38(2.15,19.02) ng/ml,P ＜ 0.01].The level of urinary sPD-1 in onset group was higher than that in remission group [1.21(0.61,2.56) pg/μg vs 0.51(0.31,0.97) pg/μg,P ＜0.001] and healthy control group [1.21(0.61,2.56) pg/μg vs 0.82(0.34,1.15) pg/μg,P ＜ 0.01].The levels of sPD-L1 in serum and urine were higher in onset and remission group than those in healthy control group (P ＜ 0.001).The level of sPD-1 in the serum was positive correlated with the numbers of CD3+,CD3+CD4+,CD3+ CD8+ T lymphocytes and CD3-CD19+,CD19+CD23+ B lymphocytes (r=0.537,0.478,0.454,0.429 and 0.374;P=0.002,0.008,0.012,0.018 and 0.042).The level of sPD-1 in the urine had positive relation with the ratio of 24 hours urinary albumin and weight (24 h UmAlb/Wt),N-acetylglucosaminidase and urinary creatinine (UNAG/Cr) and β2 microglobulin and urinary creatinine (Uβ2MG/Cr) (r=0.409,0.588 and 0.276;P=0.016,0.000 and 0.032).Conclusions The dynamic changes of sPD-1 and sPD-L1 in serum and urine suggested that PD-1/PD-L1 signaling pathway is involved in the development process of childhood primary nephrotic syndrome.

Objective: To investigate the therapeutic effects of allogeneic hematopoietic stem cell transplantation (allo-HSCT) with FLAG sequential busulfan/cyclophosphamide(Bu/Cy) conditioning regimen for refractory/relapsed acute myeloid leukemia. Methods: From February 2012 to June 2017, 21 patients with refractory/relapsed acute myeloid leukemia underwent allo-HSCT with FLAG sequential Bu/Cy conditioning regimen. Transplantation-related complications and clinical outcome were retrospectively analyzed. Results: After conditioning, no hepatic veno-occlusive disease (VOD) and grade Ⅲ hemorrhagic cystitis occurred. 76.2% (16/21) patients had fever with 4 septicemia. One patient died of septic shock before engraftment. Twenty patients achieved neutrophil engraftment with a median time of 13 days (range, 10 to 21 days). Seventeen patients achieved platelet engraftment with a median time of 18 days (range, 9 to 25 days). The cumulative incidence of acute graft-versus-host disease (aGVHD) was 39.5%, and 3 patients developed grade Ⅲ-Ⅳ aGVHD. Of 19 patients who survived more than 100 days after transplantation, 4 had local chronic graft-versus-host disease (cGVHD). Of 21 patients, the median survival time was 15 months (range, 0.5 to 67 months) post-transplantation. Transplantation-related mortality rate was 28.7%. Leukemia relapse occurred in 4 patients with a median time of 4 months (range, 3 to 8 months) after transplantation. The cumulative relapse rate at 1 year was 21.4%. The 1-year and 3-year overall survival (OS) rates were 60.7% and 54.9% respectively. Log-rank analysis revealed that bone marrow blasts ≥ 20% or extramedullary leukemia before transplantation, poor platelet engraftment and grade Ⅲ-Ⅳ aGVHD were significantly related to shortened OS (P<0.05). Conclusions Allo-HSCT with FLAG sequential Bu/Cy conditioning regimen in patients with refractory/relapsed myeloid leukemia has acceptable transplantation-related risk and relapse rate. The 1-year and 3-year OS rates are comparable with those in remission patients.

Objective To discusses the effectiveness of tocilizumab in the treatment of hypomyopathic dermatomysositis (HDM) combined with interstitial lung disease (ILD) in children. Methods The clinical characteristic, treatment, and prognosis of HDM combined with ILD were analyzed in 2 patients. The related literatures were reviewed. Results Both ten-year-old girl and 8-year-old boy had shortness of breath after activities, but had no clinical manifestations of muscle damage; both of them had typical rash, but had nornal muscle strength and muscular tension. Laboratory tests showed the elevation of serum ferritin, lactate dehydrogenase, glutamate aminotransferase, and aspartate aminotransferase. Creatine kinase slightly increased in the initial test, and then was in the normal range in the following tests. The high resolution computed tomography showed that pulmonary interstitial lesions. HDM combined ILD was diagnosed clinically. The girl died after treatment with high-dose hormones, cyclophosphamide, cyclosporine, pirfenidone, and gamma globulin failed. The boy was stabled after conventional hormone treatment plus tocilizumab (240 mg twice). His laboratory indicators were in the normal range in the follow-up. Conclusions The clinical manifestations and laboratory indicators aren't typical in childhood HDM. The mortality is high. Combined with tocilizumab treatment is effective in one case.
