Objective To summarize the clinical features of graft failure (GF)after non-T-cell depleted haploidentical hematopoietic stem cell transplantation (Haplo-HCT), and to investigate the causes and treatment. Methods A retrospective analysis was carried out on 174 patientswho accepted the non-T-cell depleted Haplo-HCT from Jan 2012 to Dec 2013. The patients′ donor specific anti human leukocyte antigen antibodies (DSA) from the peripheral blood serum were detected and those DSA positive patients were treated by immunoglobulin or plasma exchange before transplatation. Results A total of three patients with acute myeloid leukemia got GF, the incidence rate was 1.72%. The patient with primary GF was given a secondHaplo-HCT, but did not get implanted with leukemia remission and three lineages persistently low , he was died of pulmonary infection eight monthes after the second transplant. One of the secondary GF patients was given peripheral blood mononuclear cells(PBMNCs) mobilized by granulocyte colony stimulating factor (G-CSF) from the donor, and got full donor chimerism on day 16 after infusion. The disease-free survival has been for 18 months. The other case was found that DSA was positive, the mean fluorescence intensity (MFI) value was 15000, then Rituximab and PBMNCs mobilized by G-CSF were administrated successively. On day 14 after infusion the partient got full donor chimerism , and MFI turned negative. The patient has been disease-free survival for 41 months. Conclusion Graft failure is a rare but fatal complication after non-T-cell depletedHaplo-HCT, Rituximab followed by PBMNCs are effective measures for DSA related GF, as were worthy of further study.

Objective: To evaluate the long-term prognosis of coronary artery disease (CAD) patients undergoing percutaneous coronary intervention (PCI) by risk stratification with American College of Cardiology (ACC)/American Heart Association (AHA) classification of coronary lesions. Methods: Data used in this study derived from the I-LOVE-IT 2 trial. I-LOVE-IT 2 trial was a prospective, multicenter, randomized, assessor-blinded, noninferiority study. A total of 1 255 patients in I-LOVE-IT 2 trial with only one lesion and underwent biodegradable polymer drug-eluting stent implantation were included and grouped according to ACC/AHA classification of coronary lesions, namely type A/B1 lesion group (n=184), type B2 lesion group (n=457) and type C lesion group (n=614). The primary endpoint was 48-month patient-oriented composite endpoint (PoCE), a composite of all-cause mortality, all myocardial infarction, stroke, and/or any revascularization. The secondary endpoints were target lesion failure (TLF), components of PoCE, major bleeding (bleeding academic research consortium(BARC) type 3-5) and definite/probable stent thrombosis within 48 months. The incidences of endpoint events were compared in the three groups. The multivariable Cox hazard ratio model was used to analyze the independent predictors of PoCE and TLF at 48 months. Results: Incidences of PoCE at 48 months were significantly higher in patients with type C lesion compared with patients with type A/B1 (24.43%(150/614) vs. 14.13%(26/184), P<0.05) or B2 lesion (24.43%(150/614) vs. 15.97%(73/457), P<0.05). The multivariable Cox hazard ratio model showed that the type C lesion were the independent predictors of 48-month PoCE (HR=1.59, 95%CI 1.21-2.08, P<0.001) and TLF (HR=2.31, 95%CI 1.53-3.49, P<0.001). After multivariable adjustment, the HRs of PoCE for patients with type C lesion versus type A/B1 and type B2 were 1.91 (95%CI 1.25-2.92, P=0.003) and 1.64 (95%CI 1.23-2.20, P<0.001), respectively. Meanwhile, the HRs of TLF for patients with type C lesion versus type A/B1 and type B2 were 2.45 (95%CI 1.29-4.64, P=0.006) and 2.55 (95%CI 1.62-4.02, P=0.001), respectively. Conclusions: The ACC/AHA classification of coronary lesions has good discrimination with long-term outcomes for CAD patients undergoing PCI. The type C lesion is associated with a worse prognosis, enough attention should be paid in these patients during routine clinical management.

Objective:To investigate the living status and quality of life (QOL) in type1 Gaucher disease (GD1) patients who underwent long-term enzyme replacement therapy (ERT) and identify possible relevant factors affecting QOL.Methods:Clinical data and SF-36 questionnaires were recorded in 22 adult GD1 patients under regular ERT at Peking Union Medical Colleague Hospital (PUMCH) from January 1995 to June 2017.Results:13 males and 9 females were included in this study. The current median age, age at diagnosis and initial time of ERT were 41 (24-52) , 6 (1-38) and 26 (6-41) years respectively. Of these patients, 68.2% was living in less-developed regions, 86.4% were under college education, and 77.3% had personal annual income less than ￥30 000 RMB. Though after a median 16 (7-22) years of ERT, the QOL of GD1 patients was still significantly worse ( P<0.05) compared with normal Chinese population based on SF-36 questionnaires. History of splenectomy was a negative factor of QOL, mainly in physical health ( P<0.05) . Patients could get benefit from early start of ERT in both physical and mental health ( P<0.05) . Mental health was not affected by history of splenectomy and related bone diseases. Conclusion:Most adult GD1 patients at PUMCH reside in less-developed regions and have low levels of education and annual income. History of splenectomy and time to start ERT are two important factors affecting QOL. Chinese adult GD1 patients are associated with reduced QOL, even after long-term ERT.

OBJECTIVETo screen the high risk factors for relapse after allogeneic hematopoietic stem cell transplantation (allo-HSCT) in acute lymphocytic leukemia (ALL), acute myeloid leukemia (AML) and chronic myeloid leukemia (CML) respectively, then to compare the contribution of each risk factor to relapse and investigate the relevant mechanisms.

METHODSA retrospective study from single center involved in 262 evaluable cases of leukemia received allo-HSCT over the past 8 years, of them 69 cases with ALL, 90 AML (except APL) and 103 CML. Cox proportional hazard regression model was used for univariate and multivariate analysis to screen the high risk factors.

RESULTSThe risk factors significantly affecting relapse in ALL included: Cytogenetic risk classification, the cycles of initial induction chemotherapy; AML: Cytogenetic risk classification, minimal residual disease (MRD) level before transplant, reconstitution of WBC, and CD4(+)/CD8(+) lymphocyte ratio in the graft; CML: disease stage before transplant.

CONCLUSIONSThe relapse risk after HSCT of ALL mainly depends on the grade of malignancies, and the relapse risk of AML is closely related to the course of transplant. Chronic phase of CML favors a good prognosis after HSCT. Cytogenetic risk classification is the most relevant predictor of relapse after HSCT.

Objective To explore the eff cacy and safety of 6-month and 12-month dual antiplatelet therapy(DAPT)after implantation of biodegradable polymer-drug eluting stents(BP-DES) in elderly patients. Methods This study was a subgroup analysis of the I-LOVE-IT 2 trial, which was a prospectively randomized study enrolling 2737 patients receiving either a BP-SES or a DP-SES in a 2:1 ratio. This studied further divided the patients who were randomized to the BP-SES group,whose age ≥ 65 year old, in a 1:1 ratio to receive a 6-month DAPT (n=319) or 12-month DAPT (n=308)randomly before the index PCI. The primary end point of this study was 12-month target lesion failure (FhF, including cardiac death,target vessel myocardial infarction and clinically indicated target lesion revascularization)and the secondary end points was 12-month net adverse clinical and cerebral events (including all-cause death, all myocardial infarction, stroke and all bleeding). Results Rates of TLF at 12 months were 7.1% in the 6-month DAPT group and 7.2% in the 12-month DAPT group (P=0.980). No diff erences were observed in the occurrence of events in the secondary endpoint at 12 months follow-up between the 6-month DAPT group and 12-months DAPT group(14.1% versus 13.0%, P=0.726). There were no signifi cant diff erences in stent thrombosis or bleeding complications between the 2 groups. Conclusions This study shorted that 6-month DAPT did not increase the risk of TLF at 12 months after implantation of DES in elderly patients compared with 12-month DAPT. Elderly patients are at high risk of bleeding and ischemic events and study show that 6-month DAPT would be adequate. These results need to be confi rmed with trials of scale in the future.

[Purpose]To analyze the trend of gastric cancer incidence and age characteristics in Jiangsu cancer registration areas from 2009 to 2019.[Methods]Cancer registration data from 2009 to 2019 meeting quality control requirements were collected from 16 cancer registries in Jiangsu Province.The crude incidence rate and age-standardized incidence rate by Chinese standard population in 2000(ASIRC)were calculated by gender,urban/rural areas and age groups.The inci-dence trends were analyzed by Joinpoint.A birth cohort model was constructed to calculate the in-cidence rate of gastric cancer for men and women born between 1929 and 2019.The age composi-tion of gastric cancer incidence in Jiangsu Province between 2009 and 2019 was calculated and compared.[Results]The crude incidence rate and ASIRC of gastric cancer in Jiangsu cancer regi-stration areas from 2009 to 2019 showed a significant decreasing trend in both male and female or urban and rural areas,in which the decrease in male(AAPC=-1.28％,P＜0.001)was higher than that of female(AAPC=-1.17％,P=0.030),and the decrease in urban(AAPC=-1.66％,P＜0.001)was higher than that of rural(AAPC=-0.72％,P＜0.001).The incidence rates of gastric cancer in age groups of 40～79 years old showed a significant decreasing trend from 2009 to 2019 with the AAPC ranging from-6.75％to-3.54％(all P＜0.05).In age groups of 40～79 years old,the inci-dence rates of gastric cancer among people with different years of birth showed a decreasing trend with the increase of the birth year.For ASIRC,the composition of patients aged 60 years old above increased by 0.63％(95％CI:0.46％～0.81％)per year from 2009 to 2019.[Conclusion]The inci-dence rate of gastric cancer in cancer registration areas of Jiangsu Province from 2009 to 2019 showed a decreasing trend,the average age of incidence showed a trend of backward moving,and for age-standardized incidence the proportion of patients over 60 years old was increased.

OBJECTIVETo evaluate the safety and efficacy of umbilical cord-derived mesenchymal stem cells (MSCs) infusion in patients with steroid-resistant severe acute graft-versus-host disease (aGVHD).

METHODSA total of 19 patients with steroid-resistant severe aGVHD received MSCs infusion treatment. The treatment response, transplantation-related mortality, events associated with infusion and relapse rate were analyzed.

RESULTSTwo patients with grade II, 5 patients with grade III and 12 patients with grade IV aGVHD received a total of 58 infusions of MSCs. The mean total dose of MSCs was 2.13 (range 0.60 - 7.20)×10(6) cells per kg bodyweight. Seven patients received one infusion, 2 patients received two infusions, and 10 patients received three or more infusions. Eleven patients had a complete response and 4 had a partial response and 4 had no response. No patients had side-effects during or immediately after infusions, and no MSCs related tumorigenesis was detected to date. Eleven patients survived and 8 died, 4 for aGVHD, 1 for infection and 2 for aGVHD with concomitant infection and 1 for underlying leukemia relapse. The cell viability of freshly prepared MSCs is 93% (92% - 95%) by trypan blue staining. The cell viability of programmatically frozen and thawed MSCs is 72% (70% - 74%).

CONCLUSIONInfusion of umbilical cord-derived MSCs expanded in vitro is an effective therapy for patients with steroid-resistant severe aGVHD without negative impact on relapse. Freshly prepared MSCs are superior to frozen and thawed cells in terms of cell viability.

This study was aimed to analyze the survival status of patients with diffuse large B-cell lymphoma (DLBCL) and to investigate the influence of autologous hematopoietic stem cell transplantation (auto-HSCT), different pathological types, International Prognosis Idex (IPI) on prognosis. One hundred and sixteen cases of DLBCL were analyzed retrospectively. The treatment efficacy of R-CHOP alone and R-CHOP combined with auto-HSCT as well as the influence of different immunopathologic types, IPI, hypersensitive C-reactive protein (HSCRP), α-hydroxybutyric acid deaminase (HBDH) on the prognosis of DLBCL patients including overall survival (OS) rate, progression-free survival (PFS) rate were analyzed. The results indicated that the 5-year OS for all patients was 72.4%. in which 30 patients with Ann Arbor staging III-IV received auto-HSCT plus R-CHOP. The prognosis of the 30 patients was better than that of 86 cases received R-CHOP chemotherapy alone (5-year OS was 82.5% vs 69.0%, 5-year PFS was 77.1% vs 68.3%) (P < 0.05). The prognosis of patients in germinal center B-cell-like group (GCB group) was better than that of patients in activated B-cell-like group (ABC group). Some clinical features were associated with poor prognosis including OS and PFS, such as age, B symptoms, IPI scores, the level of LDH, HSCRP and HBDH (P < 0.05) in which the level of LDH, age ≥ 60 years and B symptoms were independent prognostic factors in DLBCL patients (P < 0.05). It is concluded that auto-HSCT combined with R-CHOP can improve the long-term survival of DLBCL patients. The prognosis of patients in GCB group is better than that of patients in the ABC group. The clinical features such as age, B symptoms, IPI scores and LDH are associated with prognosis.

OBJECTIVETo investigate the clinical and biological characteristics and prognosis of mixed phenotype acute leukemia (MPAL).

METHODSThirty two patients were diagnosed as MPAL by bone marrow examination, immunophenotyping, cytogenetic and molecular assay and were treated with combined chemotherapy regimens for both acute lymphoblastic and acute myeloid leukemia. Two cases were received allogeneic hematopoietic stem cell transplantation (allo-HSCT).

RESULTS(1) The incidence of MPAL in acute leukemias was 2.6%. There were 16 cases (50.0%) of mixed myeloid and B-lymphoid (M/B), 14(43.8%) myeloid and T-lymphoid (M/T), one each (3.1%) of trilineage (M/B/T) and B- and T-lymphoid (B/T) phenotype. (2) The positive rates of CD34 and HLA-DR were 87.5% and 62.5%, respectively. (3) Abnormal karyotypes were detected in 70.0% of 30 MPAL patients, which were structural and numerical abnormalities including t(9;22), 11q23 and complex karyotypes. (4) The total complete remission (CR) rate was 75.0% and the overall survival (OS) and disease-free survival (DFS) at 2 years were 14.8% and 14.2% respectively. The CR rates for M/B and M/T cases were 75.0% and 71.4% respectively. No statistical difference was observed in OS and DFS between M/B and M/T cases.

CONCLUSIONSMPAL is a rare type of acute leukemia with a high heterogeneity. The unfavorable indicators of MPAL may be factors such as abnormal karyotypes, high expression of CD34 and extramedullary infiltration. Combined regimens and more intensive therapy including allo-HSCT might contribute to improving survival.
