Abstract
Mixed phenotype acute leukemia (MPAL) is a subtype of leukemia in which lymphoid and myeloid markers are co-expressed. Knowledge regarding the genetic features of MPAL is lacking due to its rarity and heterogeneity. Here, we applied an integrated genomic and transcriptomic approach to explore the molecular characteristics of 176 adult patients with MPAL, including 86 patients with T-lymphoid/myeloid MPAL (T/My MPAL-NOS), 42 with Ph+ MPAL, 36 with B-lymphoid/myeloid MPAL (B/My MPAL-NOS), 4 with t(v;11q23), and 8 with MPAL, NOS, rare types. Genetically, T/My MPAL-NOS was similar to B/T MPAL-NOS but differed from Ph+ MPAL and B/My MPAL-NOS. T/My MPAL-NOS exhibited higher CEBPA, DNMT3A, and NOTCH1 mutations. Ph+ MPAL demonstrated higher RUNX1 mutations. B/T MPAL-NOS showed higher NOTCH1 mutations. By integrating next-generation sequencing and RNA sequencing data of 89 MPAL patients, we defined eight molecular subgroups (G1-G8) with distinct mutational and gene expression characteristics. G1 was associated with CEBPA mutations, G2 and G3 with NOTCH1 mutations, G4 with BCL11B rearrangement and FLT3 mutations, G5 and G8 with BCR::ABL1 fusion, G6 with KMT2A rearrangement/KMT2A rearrangement-like features, and G7 with ZNF384 rearrangement/ZNF384 rearrangement-like characteristics. Subsequently, we analyzed single-cell RNA sequencing data from five patients. Groups G1, G2, G3, and G4 exhibited overexpression of hematopoietic stem cell disease-like and common myeloid progenitor disease-like signatures, G5 and G6 had high expression of granulocyte-monocyte progenitor disease-like and monocyte disease-like signatures, and G7 and G8 had common lymphoid progenitor disease-like signatures. Collectively, our findings indicate that integrative genomic and transcriptomic profiling may facilitate more precise diagnosis and develop better treatment options for MPAL.

Abstract
Objective: To explore the influence of laparoscopic radical gastrectomy on patients'immune functions, coagulation functions and prognoses. Methods: Fifty-eight patients with gastric cancer who underwent laparoscopic radical gastrectomy (laparoscopic group) and 40 patients with gastric cancer who underwent traditional open surgery (traditional group) in Henan People's Hospital from May 2016 to May 2018 were selected as the subjects. The immune function and coagulation function were compared between the two groups before and after operation. The prognoses of patients underwent laparoscopic radical gastrectomy and the influencing factors were analyzed. Results: Three days after operation, the CD4(+) level and CD4(+) /CD8(+) ratio in laparoscopic group were (29.78±3.58)% and (1.01±0.18), higher than (27.23±3.47)% and (0.93±0.14) in control group (P<0.05). Three days after operation, the activated partial thromboplastin time (APTT) in laparoscopic group was (26.55±2.56) seconds, shorter than (27.86±2.73) seconds in traditional group, while the levels of fibrinogen (FIB) and D-dimer were (4.24±0.84) g/L and (377.91±47.19) μg/L, higher than (3.88±0.75) g/L and (330.28±45.11) μg/L in traditional group (P<0.05). The 5-year survival rate was 77.5% in traditional group and 72.4% in laparoscopic group, without significant difference (P>0.05). Multivariate analysis showed that lymph node metastasis was the independent risk factor for prognosis of laparoscopic radical gastrectomy (P<0.05). Conclusions: Laparoscopic radical gastrectomy can effectively reduce postoperative immunosuppression, but affect postoperative coagulation function. Lymph node metastasis is closely related to the prognosis of patient with gastric cancer. The patient's condition should be comprehensively evaluated before and after operation to determine whether the laparoscopic operation is suitable, for reducing postoperative complications and improving the prognosis.

Abstract
Objective: To summarize the clinical features, treatment and prognosis of patients with Epstein Barr virus (EBV) encephalitis after allogeneic hematopoietic stem cell transplantation (allo-HSCT) . Methods: The clinical data of 7 patients with EBV encephalitis who had undergone allo-HSCT in the First Affiliated Hospital of Soochow University from January 2012 to December 2015 were reviewed. Results: The incidence of EBV encephalitis was 0.70% (7/998) , and the median time was 63 (10-136) d after allo-HSCT. Seven patients had fever and mental disorder, of whom 4 cases of brain MRI were positive. Two patients received HLA-matched unrelated transplantation, while other 5 ones received haploidentical allo-HSCT. In conditioning regimen process, 7 patients were combined with anti-thymocyte globulin (ATG) to prevent graft versus host disease (GVHD) , of whom 6 patients had grade Ⅱ-Ⅳ acute GVHD. All patients of EBV-DNA were negative in CSF after taking anti-virus agent Rituximab. Until the last follow-up, a total of 3 patients died, 2 died of leukemia recurrence, 1 EBV encephalitis progression. Conclusion: Once suspected EBV encephalitis after allo-HSCT, brain MRI and EBV-DNA in CSF should be detected, which could improve early diagnosis of EBV encephalitis. The usage of Rituximab was effective and well tolerated.

Abstract
FMS‐like tyrosine kinase 3 (FLT3) is one of the most frequently mutated genes in hematological malignancies. FLT3 internal tandem duplication (FLT3‐ITD) mutations located in juxtamembrane domain (JMD) and tyrosine kinase domain 1 (TKD1) regions account for two‐thirds of all FLT3 mutations. The outcome of patients remains unsatisfactory, with low survival rates. It is not yet known whether the different mutations within the FLT3 gene are all associated with patient outcome. In addition, the cause of FLT3‐ITD in‐frame duplication events remains unknown. Although there are some published studies investigating the FLT3‐ITD mutation and its clinical implications in Chinese acute myeloid leukemia (AML) patients, sample sizes tend to be small and detailed molecular profiles of FLT3 mutations are lacking in these studies. In our study, 227 FLT3‐ITD sequences were analyzed from 227 Chinese de novo AML patients. ITD were next classified into 3 types based on molecular profiles of insertion DNA sequences: DNA complete duplication (type I), DNA partial duplication (type II) and complete random sequence (type III). From the 154 patients, we confirmed that high ITD allelic ratio (≥.5) and allogeneic stem cell transplant treatment under CR1 are independent prognostic factors. We also presented evidence that ITD integration sites in the hinge region or beta1‐sheet region are an unfavorable prognostic factor in adult AML patients with FLT3‐ITD mutations. These findings may help to decipher the mechanisms of FLT3‐ITD in‐frame duplication events and stratify patients when considering different therapeutic combinations.

Abstract
OBJECTIVE To explore the effect of BCR-ABL gene transcripts on Leukemia-free survival (LFS) and prognosis of patients with Philadelphia chromosome positive acute lymphoblastic leukemia (Ph+ ALL) after allogeneic hematopoietic stem cell transplantation (allo-HSCT). METHODS The clinical data of 107 cases of Ph+ B-ALL patients received allo-HSCT from July 2006 to November 2014 in the First Affiliated Hospital of Soochow University were collected and the relationship between the clinical characteristics and LFS after transplantation was analyzed. RESULTS Out of 107 Ph+ ALL patients (64 males and 43 females) with a median age of 30(7 to 54)years old, 35.5% (38/107) cases relapsed after transplantation within a median time of 6.9 (1.5 to 40.7) months. A total of 39 (36.4%) cases died within a median time of 19.8 (3.6 to 83.7) months after HSCT, of which 51.3% (20/39) due to disease relapse and 25.6% (10/39) due to infection. BCR-ABL gene transcripts of 49 cases turn into negative before transplantation, of which the expected 5-year cumulative incidence of relapse (CIR), non-relapse mortality (NRM) and overall survival (OS) were 26.5%, 29.5% and 41.6%, respectively. Another 49 cases still had a positive BCR-ABL gene transcripts before transplantation, of which the life expectancy of 5 year CIR, NRM and OS were 64.4%,8.9% and 48.9%, respectively. Compared with BCR-ABL positive patients, BCR-ABL negative patients showed a lower CIR (P<0.001), a higher NRM (P=0.030) and a similar OS (41.6% versus 48.9%, P=0.497). Multivariate analysis showed that BCR-ABL positive (P=0.016) and a disease statusphase ≥CR2 (P<0.001) before HSCT were independent risk factors for LFS, while the age underwent HSCT was the principal element affecting prognosis (P<0.001). CONCLUSION Both the relapse and infection are the main causes of death in the patients after transplantation. A disease status ≥CR2 and the BCR-ABL positive before transplantation are 2 independent risk factors of LFS in the patients with Ph+ ALL after allo-HSCT.

Abstract
OBJECTIVE Two distinct forms of FMS-like tyrosine kinase 3 (FLT3) mutations, internal tandem duplication (ITD) in the juxtamembrane domain and point mutation within the activation loop of the tyrosine kinase domain (TKD), have been identified in considerable number of patients with AML. This study was aimed to analyze the impacts of these mutations on clinical outcomes, and assess the efficacy of different therapeutic regimens (allo-HSCT, sorafenib, or conventional chemotherapy) for AML patients with FLT3 mutations after the standard induction therapy. MATERIALS AND METHODS We analyzed DNA samples from 158 consecutive de novo AML patients (18-60 years, excluding APL) with FLT3 mutations between July 2010 and October 2015. RESULTS We found that AML patients with FLT3-TKD mutations have more favorable clinical outcomes than those with FLT3-ITD mutations. We also found that allo-HSCT therapy subgroup achieved longer OS and RFS than non-allo-HSCT therapy subgroup for FLT3-ITD positive patients (p < 0.001, p = 0.071). However, compared with the clinical outcomes in non-primary refractory patients, sorafenib did not show an obvious beneficial effect for the primary refractory patients. Further study on a large scale is still recommended. CONCLUSIONS FLT3-TKD-mutated AML patients have more favorable clinical outcomes than those with FLT3-ITD mutations. Allo-HSCT therapy subgroup achieved longer OS and RFS than non-allo-HSCT therapy subgroup for FLT3-ITD positive patients. Compared with the clinical outcomes in non-primary refractory patients, sorafenib did not show an obvious beneficial effect for the primary refractory patients.

Abstract
Objective: To explore the impact on prognosis in favorable-risk acute myeloid leukemia (AML) patients with different consolidation regimens after first complete remission (CR(1)). Methods: A total of 107 cases of non-refractory adult AML from January 2010 to June 2015 in single center were enrolled in the study. HD-Ara-C group (38 cases) as the control group, we explore the prognosis in three consolidation regimens, including micro-transplantation (16 cases) , autologous transplantation (auto-PBSCT, 14 cases) , allogeneic transplantation (allo-HSCT, 39 cases). Results: Of 107 patients (59 males and 48 females) , with a median age of 33 (16-59) years old and a median follow-up of 36.5 (5.3-79.1) months, the overall relapse rate was 20.6% (22/107) , and overall mortality rate was 18.7% (20/107). The 5 years cumulative relapse rate (CIR) of HD-Ara-C, micro-transplantation, auto-PBSCT and allo-HSCT group were 39.7%, 6.2%, 14.3% and 5.6%, respectively (P<0.001). The CIR of the observed group was lower than the HD-Ara-C group. The 5 years progression-free survival (PFS) rate of HD-Ara-C, micro-transplantation, auto-PBSCT and allo-HSCT group were 44.7%, 93.8%, 85.7% and 78.1%, respectively (P=0.011). The PFS of observed groups were similar, but superior to that in HD-Ara-C group. The 5-year overall survival (OS) in four groups was 54.9%, 100%, 92.9% and 77.4%, respectively (P>0.05). Multiple factors analysis showed that compared to HD-Ara-C regimen, allo-HSCT could improve PFS (HR=0.376, P=0.031) , but not OS (P>0.05) ; micro-transplantation and auto-PBSCT could not improve the PFS or OS (P>0.05). Conclusion: As compared with HD-Ara-C regimen, allo-HSCT could obviously decrease CIR, improve PFS, but treatment-related mortality is high. These results show that auto-PBSCT and micro-transplantation have similar outcomes, compared to HD-Ara-C regimen, so both can be used as a option of consolidation treatment for favorable-risk AML.

Abstract
B cells are involved in chronic graft-versus-host disease (cGVHD) pathogenesis, and Rituximab may have a therapeutic effect on cGVHD in allogeneic hematopoietic stem cell transplantation (allo-HSCT) patients. Herein, we retrospectively evaluated the prophylactic effect of Rituximab on cGVHD in a group of Chinese allo-HSCT patients. A total of 102 patients, who suffered Epstein Barr virus (EBV) viremia within 100 days after allo-HSCT, were included in this study. Fifty patients received Rituximab (375 mg/m2 weekly) for EBV viremia, while fifty-two patients did not receive Rituximab. A competing risk model was adopted to compare cumulative incidence of cGVHD, cumulative incidence of relapse (CIR) and transplantation-related mortality (TRM) between two groups. Cumulative incidence of cGVHD in the Rituximab group was lower than in controls (P = 0.0579). Multivariate analyses confirmed that Rituximab was an independent factor for the reduction of cumulative cGVHD incidence (P = 0.0069). No significant difference was observed in CIR (P = 0.39) or TRM (P = 0.48) between two groups and 2-year OS and DFS were comparable (OS, P = 0.667; DFS, P = 0.571). Administration of Rituximab in the early post-transplantation phase may protect against cGVHD in allo-HSCT patients without increasing CIR or TRM.

Abstract
Objective: By analyzing the risk factors for occurrence of differentiation syndrome (DS) during induction therapy in newly-diagnosed acute promyelocytic leukemia (APL) patients, a prediction nomogram for DS was established and the accuracy of this nomogram was validated. Methods: The modeling group was made up of 130 classical APL patients during the period of 1st January 2011 to 31st December 2013. After single factor screening of clinical variables, the logistic regression model was used to identify the final model variables. A nomogram subsequently established by R software was validated by Bootstrap resampling as internal validation. Concordance index (C-index) was used for the accuracy evaluation of the nomogram, and calibration curves were painted to test the actual observation and the nomogram-prediction of occurrence rate of DS. Results: Occurrence rate of DS in 130 APL patients was 30.0%; In multivariate analysis, body mass index (BMI) ≥24 kg/m2 and without using steroids for prevention of DS were identified as independent risk factors. The C-index of the nomogram for predicting DS was 0.818 (95% CI 0.741-0.895). The calibration curves showed good concordance of occurrence rate of DS between nomogram-prediction and actual observation. Conclusion: The nomogram was successfully established as a more accurate and visible tool for predicting the occurrence rate of DS in APL patients.

Abstract
PURPOSE To compare the relative merits of imatinib and allogeneic hematopoietic stem cell transplantation (allo-HSCT) for chronic myelogenous leukemia (CML). MATERIALS AND METHODS This cohort study was designed to compare the outcomes of imatinib (n=292) versus allo-HSCT (n=141) for CML, the clinical data of these patients being retrospectively analyzed so as to compare the event free survival (EFS) and overall survival (OS) between these two groups with patients in the chronic phase (CP) and advanced phases, including accelerate (AP) and blast phases (BP). RESULTS (1) Patients treated with imatinib (278 in the CP) demonstrated superior EFS, OS, 5-year EFS and 5-year OS rates of 88.5% versus 70.0% (P<0.05), 93.2% versus 80.0% (P<0.05), 84% versus 75.0% (P<0.05) and 92% versus 79.0% (P<0.05), respectively, to those treated with allo-HSCT (120 patients in the CP). (2) Both treatments resulted in similar survival, with EFS and OS rates of 42.9% versus 47.6% (P>0.05), 42.9% versus 57.1% (P>0.05), respectively, for imatinib (14 patients in the AP and BP) and allo-HSCT (21 patients in the AP and BP). CONCLUSIONS Imatinib confers signi cant survival advantage (EFS and OS) for CML patients with CP compared with allo-HSCT treatment. However, the outcomes are equally good with both treatments in AP and BP patients.

Abstract
Crab grows by periodic molting, which is controlled by molt-inhibiting hormone (MIH) and ecdysteroids. Untranslated regions (UTRs) play crucial roles in the posttranscriptional regulation of gene expression. In this study, using crab collected from Changjiang (Yangtze), Huanghe (Yellow), Liaohe, and Yalujiang rivers, 33 haplotypes of the 3ꞌ-UTR of ecdysteroid-regulated protein (ERP) gene were identified, of which 14 haplotypes were observed in more than one individual. One hundred and forty clones of haplotype h2 (41.5%) were observed in samples from all the 4 rivers. Three haplotypes were observed to be insertions. For the whole crab sample, we found a positive Tajima's D value and a negative Fu's Fs test (Tajima's D value = 0.98726; Fu's Fs test = -27.382), although the P values were not significant (P > 0.10). The network profile of these 33 haplotypes presented a single core pattern with h2 as the core. In this study, we found that the UTR of ERP gene had a considerably high genetic polymorphism among crab from regions south to north of China. Furthermore, we observed a relatively high genetic divergence among different haplotypes, which would suggest a high diversity of the crab gene pool.

Abstract
C-type lectins are a superfamily of Ca(2+)-dependent carbohydrate-recognition proteins that are well known for their participation in pathogen recognition and clearance. In this study, a putative C-type lectin fold (MyCLF) gene was identified from the Japanese scallop Mizuhopecten yessoensis. The full-length of MyCLF was 645 bp, encoding a polypeptide of 167 amino acids. MyCLF carried a signal peptide of 20 amino acid residues, and a single carbohydrate recognition domain, having relatively high amino acid sequence conservation with C-type lectins reported for other bivalves. The expression of MyCLF mRNA transcripts in adult tissues, after bacterial challenge and during different developmental stages was determined using real-time quantitative RT-PCR. MyCLF was mainly distributed in the mantle, gill, and kidney. The expression of MyCLF clearly increased 3 h after Vibrio anguillarum challenge, and dropped to a minimum level after 9 h compared to the control group. During embryonic development, the expression level increased in the gastrulae, trochophore and early D-shaped larvae, decreased in D-shaped larvae, and then increased hundreds of times in metamorphosing larvae. The results suggested that MyCLF was involved in an immune response and it may play important roles during the metamorphosis phase of M. yessoensis.

Abstract
We conducted a case-control study to clarify the asso-ciations between inflammatory cytokine, including interleukin (IL)-1b, IL-6, IL-8, and IL-10, polymorphisms and risk of acute pancreatitis. Genotyping analyses of IL-1β+3954 C/T (rs1143634), IL-1β-511 C/T (rs16944), IL-6 -174 G/C (rs1800795), IL-6 -634 C/G (rs1800796), IL-8 -251T/A (rs4073), IL-10 -1082A/G (rs1800896), and IL-10 -819C/T (rs1800871) were conducted using polymerase chain reaction-restriction fragment length of polymorphism. Unconditional logistic regression analysis was utilized to assess the potential association be-tween genotype frequencies and risk of acute pancreatitis. Multivari-ate regression analyses showed that subjects carrying the IL-8 -251 AA genotype had a significantly increased risk of acute pancreatitis, with an adjusted odds ratio (95% confidence interval) of 1.55 (1.02-2.36). However, we found no significant association between IL-1β +3954 C/T, IL-1β -511 C/T, IL-6 -174 G/C, IL-6 -174 G/C, IL-6 -634 C/G, IL-10 -1082A/G, or IL-10 -819C/T polymorphisms and risk of acute pancreatitis. We found that the IL-8 -251T/A polymorphism was associated with a higher susceptibility to acute pancreatitis in a Chinese population.
