Objective To investigate the role of miR-125b on hepatic angiogenesis,with the hope of providing new targets for the prevention and treatment of liver fibrosis.Methods The human hepatic sinusoidal endothelial cells were transfected with miR-125b mimics and inhibitors,and the mRNA and protein expression of vascular endotheli-al growth factor(VEGF),cluster of differentiation antigens 31(CD31),von Willebrand factor(vWF),collagenⅣ,and laminin(LN)were detected by qRT-PCR and ELISA,and the expression of nitric oxide(NO)was detec-ted by fluorescent probe,scanning electron microscopy detected the alteration of the window holes on the surface of human hepatic sinusoidal endothelial cells,angiogenesis assay was performed to observe the neovascularization of each group,and dual luciferase reporter gene assay was performed to validate the targeting relationship between miR-125b and VEGF.Results qRT-PCR and ELISA showed that compared with the negative control group,the mRNA and protein expressions of VEGF,CD31,vWF,Collagen Ⅳ,and LN significantly decreased after miR-125b mimic transfection(P<0.05),while the mRNA and protein expressions of VEGF,CD31,vWF,CollagenⅣ,and LN were significantly increased after transfection with miR-125 b mimics(P<0.05);fluorescent probe detection showed that compared with the negative control group,the average fluorescence of intensity expression NO decreased significantly(P<0.05),while the average fluorescence intensity expression of NO increased significant-ly after miR-125b inhibitor transfection(P<0.05);the number of fenestrations on the surface of human liver sinu-soidal endothelial cells significantly increased after miR-125b mimic transfection(P<0.05),while the number of fenestrations on the surface of human liver sinusoidal endothelial cells decreased significantly after miR-125 b inhibi-tor transfection(P<0.05);angiogenesis assay showed that compared with the negative control group,the number of angiogenesis significantly decreased after miR-125b mimic transfection(P<0.05),while the number of angio-genesis significantly increased after miR-125b inhibitor transfection(P<0.05);dual luciferase reporter gene assay showed that compared with negative control group,the expression of relative fluorescence intensity after transfection of miR-125b mimics in VEGF wild-typ significantly decreased(P<0.05),while the expression of relative fluores-cence intensity after transfection of miR-125b mimics in VEGF mutant significantly decreased(P>0.05).Con-clusion miR-125b can inhibit liver angiogenesis and thus play an anti-fibrosis role,which can provide a new ref-erence for the prevention and treatment of chronic liver disease and the development of new drugs.
ABSTRACT
Complex systems exist widely,including medicines from natural products,functional foods,and bio-logical samples.The biological activity of complex systems is often the result of the synergistic effect of multiple components.In the quality evaluation of complex samples,multicomponent quantitative analysis(MCQA)is usually needed.To overcome the difficulty in obtaining standard products,scholars have proposed achieving MCQA through the"single standard to determine multiple components(SSDMC)"approach.This method has been used in the determination of multicomponent content in natural source drugs and the analysis of impurities in chemical drugs and has been included in the Chinese Pharmacopoeia.Depending on a convenient(ultra)high-performance liquid chromatography method,how can the repeatability and robustness of the MCQA method be improved?How can the chromatography conditions be optimized to improve the number of quantitative components?How can computer software technology be introduced to improve the efficiency of multicomponent analysis(MCA)?These are the key problems that remain to be solved in practical MCQA.First,this review article summarizes the calculation methods of relative correction factors in the SSDMC approach in the past five years,as well as the method robustness and accuracy evaluation.Second,it also summarizes methods to improve peak capacity and quantitative accuracy in MCA,including column selection and two-dimensional chromatographic analysis technology.Finally,computer software technologies for predict-ing chromatographic conditions and analytical parameters are introduced,which provides an idea for intelligent method development in MCA.This paper aims to provide methodological ideas for the improvement of complex system analysis,especially MCQA.
ABSTRACT
Objective:To investigate the factors affecting the accuracy of electronic portal imaging device (EPID)-based in vivo dose verification in radiotherapy for patients with lung and esophageal cancers, and to recommend the workflow and specifications for the application of the in vivo dose verification. Methods:This study randomly selected 32 patients who received radiotherapy for esophageal and lung cancers at the Department of Radiation Oncology, Jinhua Municipal Central Hospital from May to August 2022, including 14 lung cancer cases and 18 esophageal cancer cases. Using a uRT-linac 506c linear accelerator, these patients were treated according to the dynamic intensity-modulated radiotherapy (dIMRT) and EPID-based In vivo dose verification ( In vivo EPID) plans developed with the uRT-TPOIS planning system. The In vivo dose verification performed during the treatment included 238 fractions of In vivo EPID and 80 fractions of image-guided radiotherapy (IGRT) for the lung cancer cases, as well as 414 fractions of In vivo EPID and 105 fractions of IGRT for the esophageal cancer cases. The 2D γ passing rate for each irradiation field was obtained according to the set threshold value. Furthermore, fractioned irradiation fields with γ-passing rates below the threshold value were analyzed, and primary factors decreasing the γ-passing rate were further analyzed by combining the online CT images and 3D reconstruction-derived dose. Results:For lung and esophageal cancers, the mean γ-passing rates were 95.1% ± 5.7% and 96.5% ± 4.5%, respectively at 3 mm/5%; 91.5% ± 8.4% and 92.2% ± 4.9%, respectively at 3 mm/3%, and 79.1% ± 14.7% and 83.7% ± 8.2%, respectively at 2 mm/2%, indicating no statistically significant differences between two cancers ( P > 0.05). The average γ passing rate for beam orientations near 0°/180° (Group A) was higher than those near 90°/270° (Group B) 3 mm/5%: Z = -25.4, P < 0.05; 3 mm/3%: Z = -26.8, P < 0.05). The IGRT correction of setup errors significantly improved the γ passing rates (96.3% ± 5.1% and 96.4% ± 4.9%, respectively at 3 mm/5%, Z = -5.50, P < 0.05; 92.3% ± 8.0% and 91.3% ± 7.7%, respectively at 3 mm/3%, Z = -9.54, P < 0.05). The results of In vivo dose verification were affected by changes in the volumes and motion of tumors and normal tissues, radiotherapy positioning, and adequacy of pre-treatment preparation. Conclusions:EPID-based In vivo dose verification during radiotherapy can avoid incorrect irradiation. However, it is necessary to standardize the workflow of the EPID-based In vivo dose verification to avoid the decrease in the γ passing rate caused by artificial factors.
ABSTRACT
@#Objective This study aims to explore the correlation between white blood cell count (WBC),absolute neutrophil count (ANC),relative neutrophil count (RNC) and neurological impairment,poor prognosis at discharge and 90 days after onset.Methods This study was a retrospective study,including patients aged 18 to 45 years old with first ischemic stroke within 72 hours.NIHSS score at discharge,mRS score at discharge and 90 days were used as outcome.Multivariate logistic regression was used to analyze the relationship between WBC quartile,ANC,RNC and neurological deficit (NIHSS score>4) and poor prognosis (mRS score 2~5).Results WBC>7.82×10 9/L was independently associated with moderate and severe neurological deficit at discharge and poor prognosis at 90 days.The ANC was only associated with poor prognosis at 90 days,independently.The RNC was an independent risk factor for moderate and severe neurological impairment at discharge,poor prognosis at discharge and 90 days.Conclusion WBC>7.82×10-9/L is an independent risk factor for moderate and severe neurological impairment at discharge and poor prognosis at 90 days in young patients with stroke.The increase of RNC,which is independently related to moderate and severe neurological impairment and poor prognosis,is more indicative than ANC for poor prognosis in young patients with stroke.
ABSTRACT
Objective:To explore the clinical characteristics, treatment and prognosis of myeloid sarcoma(MS).Methods:From January 2010 to May 2019, clinical data were reviewed for 89 MS cases. Age, gender, site of onset, type, comorbid diseases, lymphatic characteristics and disease remission status were analyzed. And 1-year survival rates were explored for different treatments including whether or not chemotherapy, transplantation and using hypomethylated drugs(HMAs)for maintenance after transplantation.Results:Among them, 21 cases had the data of chromosome karyotypic analysis and next generation sequencing and 8 patients underwent allogeneic hematopoietic stem cell transplantation(allo-HSCT). The 1-year overall survival rates(OS)of primary MS, MS with intramedullary disease and MS relapse after leukemic remission were 16.0%, 37.5% and 36.9% respectively( P=0.013). The 1-year OS of local treatment(surgical resection, intrathecal injection and local radiotherapy), chemotherapy plus local treatment and chemotherapy plus allo-HSCT was 0, 28.1% and 72.9% respectively( P=0.003). After two courses of treatment, the 1-year OS of patients with complete and incomplete remissions were 34.9% and 10.0% respectively( P=0.008). Half(4/8)MS patients relapsed within 1 year after transplantation and had a short survival.Three patients received decitabine after HSCT and all of them survived for a long time. Conclusions:Chemotherapy plus HSCT is efficacious for MS. Decitabine maintenance treatment after transplantation may prolong recurrence-free survival. However, a larger sample size is required for further clinical verifications.
ABSTRACT
Objective: To explore the impact of gestational age on prenatal ultrasonic diagnosis of fetal ascites and fetus' outcome. Methods: Totally 58 pregnant women (58 fetuses) with fetal peritoneal effusion diagnosed with ultrasound were divided into 2 groups according to the gestational weeks of the first discovery of fetal peritoneal effusion, group (0.05). Pregnancy was terminated in 12 cases (12/20, 60.00%) in group and 10 cases (10/38, 26.32%) in group Ⅱ. Seven cases (7/20, 35.00%)in group and 20 cases (20/38, 52.63%) in group Ⅱ had good fetal outcome, but 5 newborns (5/38, 13.16%) died within 7 days after birth in group Ⅱ. The rate of termination in group was higher than that in group Ⅱ (χ2=6.32, P=0.01). Conclusion: Gestational age has impact on prenatal diagnosis and outcome of fetus with ascites.
ABSTRACT
Objective:To compare the efficacy of the second generation tyrosine kinase inhibitor dasatinib combined with allogeneic hematopoietic stem cell transplantation(allo-HSCT)or chemotherapy in the treatment of Ph + acute lymphoblastic leukemia (Ph + ALL). Methods:A total of 56 Ph + ALL patients received dasatinib from January 2014 to June 2018. According to whether or not allo-HSCT was performed, they were divided into transplantation group(n=22)and chemotherapy group(n=34). The total survival rate(OS), disease-free survival rate(DFS), relapse and non-recurrence mortality(NRM)were compared between two groups. Results:The 2-year OS, DFS and cumulative recurrence rates were 69.1 % vs 47.8 %, 62.2 % vs 43.1 % and 14.6 % vs 44.1 % in transplantation and chemotherapy groups respectively. Significant inter-group differences existed in 2-year DFS, DFS and cumulative recurrence rates. The value of NRM was higher in transplantation group than that in chemotherapy group(18.6 % vs 14.1 %). However, the difference was statistically insignificant( P=0.476). Conclusions:The efficacy of dasatinib plus allo-HSCT is superior to that of dasatinib plus chemotherapy in the treatment of Ph + ALL.
ABSTRACT
Purpose@#The epidemiology of B-cell non-Hodgkin lymphoma (BNHL) in Asia is not well described, and rates of second primary malignancies (SPM) in these patients are not known. We aimed to describe temporal changes in BNHL epidemiology and SPM incidence in Korea. @*Materials and Methods@#A retrospective cohort study used claims data from the National Health Insurance Service that provides universal healthcare coverage in Korea. Newly diagnosed patients aged at least 19 years with a confirmed diagnosis of one of six BNHL subtypes (diffuse large cell B-cell lymphoma [DLBCL], small lymphocytic and chronic lymphocytic [CLL/SLL], follicular lymphoma [FL], mantle cell lymphoma [MCL], marginal zone lymphoma [MZL], and lymphoplasmacytic lymphoma/Waldenström’s macroglobulinemia [WM]) during the period 2006-2015 were enrolled and followed up until death, dis-enrolment, or study end, whichever occurred first. Patients with pre-existing primary cancers prior to the diagnosis of BNHL were excluded. @*Results@#A total of 19,500 patients with newly diagnosed BNHL were identified out of 27,866 with non-Hodgkin lymphoma (NHL). DLBCL was the most frequently diagnosed subtype (41.9%-48.4% of NHL patients annually, 2011-2015). Standardized incidence of the six subtypes studied per 100,000 population increased from 5.74 in 2011 to 6.96 in 2015, with most increases in DLBCL, FL, and MZL. The incidence (95% confidence interval) of SPM per 100 person-years was 2.74 (2.26-3.29) for CLL/SLL, 2.43 (1.57-3.58) for MCL, 2.41 (2.10-2.76) for MZL, 2.23 (2.07-2.40) for DLBCL, 1.97 (1.61-2.38) for FL, and 1.41 (0.69-2.59) for WM. @*Conclusion@#BNHL has been increasingly diagnosed in Korea. High rates of SPM highlight the need for continued close monitoring to ensure early diagnosis and treatment.

ABSTRACT
Objective To investigate the efficacy and safety of maintenance treatment with low-dose decitabine after allogeneic stem cell transplantation (allo-HSCT) for high-risk acute lymphoblastic leukemia (ALL). Methods The data of 10 patients with high-risk ALL who received maintenance therapy with low-dose decitabine after allo-HSCT in the First Affiliated Hospital of Zhengzhou University from July 2016 to March 2018 was collected. The incidence of post-transplant relapse and graft-versus-host disease (GVHD) and the safety of the treatment protocol were analyzed. The cumulative incidence of relapse (CIR) rate, disease-free survival (DFS) rate and overall survival (OS) rate were estimated by Kaplan-Meier method. Results Two patients relapsed and the median relapse time of these 10 patients was 575 days after transplantation. The 1-year CIR, OS and DSF rates were 16.7%, 100.0% and 83.3%, respectively. At the end of follow-up, the DFS time after transplantation of 2 patients with p53 mutation were 23 months and 11 months, respectively. There was no induction or alleviation of GVHD caused by decitabine treatment. Nine patients developed grade Ⅰ-Ⅱmyelosuppression. Three patients had unexplained thrombocytopenia after transplantation and their platelet counts recovered after decitabine treatment. Conclusion Maintenance therapy with low-dose decitabine has low hematologic toxicity without increasing GVHD, which could be a maintenance treatment option to prevent relapse after transplantation for patients with high-risk ALL.
ABSTRACT
Objective To investigate the expressions of CD28 and CD117 in patients with newly diagnosed multiple myeloma (MM) and their clinical significances. Methods The clinical data of 115 newly diagnosed MM patients in the First Affiliated Hospital of Zhengzhou University from May 2015 to December 2017 were retrospectively analyzed. The expressions of CD28 and CD117 were detected by using multiparameter flow cytometry. The relationship between the expressions of CD28 and CD117 and MM staging and clinical parameters was analyzed. The staging was performed according to the International Staging System (ISS). Results Among these 115 patients, there were 15 patients with CD117 positive and 30 patients with CD28 positive. Erythrocyte sedimentation rate (r = -0.481, P = 0.039), Cˉreactive protein level (r = -0.314, P=0.015), the proportion of plasma cells detected by bone marrow cytology (r=-0.027, P=0.001) were negatively correlated with CD117 positive expressions. CD28 positive expression was positively correlated with lactate dehydrogenase level (r = 0.249, P = 0.033) and ISS stage (r = 0.319, P = 0.017), while it was negatively correlated with hemoglobin level (r = -0.372, P = 0.026). CD28 positive was associated with light chain type, and nonˉsecretory type mostly occurred (P = 0.016). The incidence of osteolytic lesions in CD28 positive group and CD117 positive group was high, but there was no statistical difference between CD28 positive group, CD117 positive group and CD28 negative group, CD117 negative group (P = 0.052, P=0.479). Conclusions The positive expression of CD117 in the early stage of MM patients is higher than that in the advanced stage, and the expression of CD28 positive in the advanced stage of MM patients is higher than that in the early stage. CD28 and CD117 can be used as indicators of prognosis stratification in the patients with newly diagnosed MM.
ABSTRACT
Objective To investigate the efficacy and safety of domestic bortezomibˉbased chemotherapy for patients with multiple myeloma (MM). Methods The clinical data of 60 MM patients treated with domestic bortezomibˉbased chemotherapy regimen (the observation group) in the First Affiliated Hospital of Zhengzhou University from April 2018 to October 2018 were retrospectively analyzed, which were compared with 112 MM patients treated with original treatment regimen (the control group) at the same hospital from November 2010 to November 2014. According to the disease stage, the patients were divided into newly diagnosed MM (NDMM) group and relapsed refractory MM (RRMM) group, and efficacy and adverse reactions of domestic bortezomib were evaluated. Results The total response rate (ORR) of the observation group was 71.7% (43/60), severe complete response (sCR) + complete response (CR) rate was 16.7% (10/60), very good partial response (VGPR) rate was 18.3% (11/60), and partial response (PR) rate was 36.7% (22/60). The ORR of NDMM group (45 cases) and RRMM group (15 cases) was 82.2% (37/45) and 40.0% (6/15), respectively, and the difference was statistically significant (χ2= 9.877, P < 0.05). There was no significant difference between ISS stage Ⅰ+Ⅱ and stage Ⅲ [ORR: 75.7% (28/37) vs. 65.2% (15/23), respectively; χ2=0.764, P >0.05]. ORR and CR rates in the NDMM group and RRMM group of the observation group and the control group were not statistically different (all P>0.05). In the treatment of bortezomibˉbased chemotherapy, the common adverse reaction was peripheral neuropathy, mostly belonging to grade 1-2. Other side effects included hematocytopenia, gastrointestinal events and herpes zoster, which could be alleviated or restored to normality after supportive treatments. One patient died of pulmonary infection, respiratory failure and septic shock during the intermittent period of chemotherapy. Conclusion ORR of domestic bortezomibˉbased chemotherapy in treatment of the patients with MM is high, and the incidence of adverse reactions shows no significant increase compared with original drugs.
ABSTRACT
Objective@#To investigate the association between the time of neutrophils to the lowest and prognosis of patients with esophageal squamous cell carcinoma (ESCC) treated with non-operative therapy.@*Methods@#The clinical data of 325 non-operative treated ESCC patients were collected in this study. The X-title software was applied to establish optimal threshold of neutrophil reduction to the lowest value. According to the optimal threshold, the patients were divided into early group (115 cases) and late group (210 cases). The clinical features and survival time of the two groups were compared, and the factors of prognosis were analyzed by Cox regression model with univariate and multivariate analysis.@*Results@#The X-title software demonstrated the optimal cutoff values for the time of neutrophils to the lowest was 39 days. The median overall survival time was 21.0 months in the early group which was significantly higher than that in the late group (16.0 months). Multivariate Cox regression analysis showed that the treatment methods and the time of neutrophils to the lowest were independent factors for overall survival of patients with ESCC treated by non-surgical therapy. Compared with radiotherapy alone, concurrent chemoradiation could benefit the survival (HR=0.64, P=0.026). The prognosis of patients in the late group of neutrophils to the lowest (HR=1.38, P=0.038) was poor compared with the early group. Furthermore, stratified by treatment methods, the overall survival of two groups showed statistically significant difference only in patients received concurrent chemoradiation. The mortality risk in the late group was higher than that in the early group (HR=3.53, P=0.010).@*Conclusion@#The time of neutrophils to the lowest is an independent prognosis factor for non-operative treated ESCC patients. The prognosis of patients in the early group is better than that in the late group.

Objective To investigate the effect of recombinant human interleukin 11(rhlL-11)in the treatment of idiopathic thrombocytopenic purpura(ITP)on the levels of Th1,Th2 and the expression of their transcription factors T-bet mRNA,GATA-3 mRNA.Methods Fifty-six cases adult ITP patients hospitalized in the department of hematology of the Second People's Hospital of Datong from May 2015 to December 2016 were collected,including 21 males and 35 females,aged 29~73 years; 10 healthy people in the same period were enrolled as control group,4 males and 6 females,aged 20~52 years.Th1 and Th2 cell ratio and Th1/Th2 ratio of ITP patients were detected by flow cytometry before and after treatment.The expression levels of transcription factor T-bet and GATA-3 were measured using real-time fluorescence quantitative reverse transcription polymerase chain reaction(RT-PCR)before and after treatment.Results The effective rate of rhlL-11 in ITP treatment was 76.8%(43/56).For the effective patients,the median PLT after treatment increased(25.0(15. 0,36.0)×109/L vs.68.0(49.0,108.0)×109/L,Z=-5.712,P<0.001); Th1 cells decreased,compared with that before the treatment(14.8 %(12.6%,17.6%)vs.10.6 %(9.8%,12.6%),Z=-4.825,P<0.001);Th2 cell increased,compared with that before the treatment(0.4%(0.3%,0.5%)vs.1.2%(0.9%,1.4%), Z=-5.720,P<0.001); Th1/Th2 decreased,compared with that before the treatment(40(30,49)vs.10.6(7.8,12.0),Z=-5.711,P<0.001];the expression level of T-bet mRNA decreased(0.36(0.18,0.51)vs 0.09(0.05,0.13),Z=-2.668,P=0.008);the expression level of GATA-3 mRNA increased,compared with that before treatment(0.04(0.03,0.05)vs.0.12(0.09,0.15),Z=-2.366,P=0.018).For ineffective patients,the median PLT before treatment was(11.0(8.0,15.5)×109/L),and the median PLT after treatment was(15.0(10.0,19.5)×109/L)(Z=-3.027,P=0.002); there was no significant difference in Th1,Th2, ratio of Th1/Th2 and T-bet and GATA-3 mRNA expression level before and after treatment in patients with ITP (P>0.05).Conclusion rhIL-11 can effectively correct the imbalance in Th1 and Th2 cells and the imbalance of T-bet and GATA-3 in ITP patients,but it has no obvious therapeutic effect on a small number of patients
ABSTRACT
Objective To investigate the viral etiology and the epidemilogy of acute upper respiratory tract infection in Hebei Province from 2013 to 2015,providing scientific basis for diagnosis,prevention and control of the respiratory tract infection.Methods l 551 throat swab samples of the acute upper respiratory infection patients from four hospitals in Hebei Province were collected,Multiplex real-time PCR was used to detect 15 kinds of respiratory tract viruses for all specimens after nucleic acids extraction.Results Totally 714 positive samples were obtained from 1 551 samples,with a positive rate of 46.03%.Human rhinovirus(186,11.99%)was detected as the most common viral species,followed by human parainfluenza 3(167,10.77%),respiratory syncytial virus (122,7.87%),adenovirus (108,6.96%),influenza B virus (56,3.61%),human metapneumovirus(40,2.58%),influenza A virus(39,2.51%),human boca virus (38,2.45%),human parainfluenza 1 (35,2.26%),human coronavirus-229E/NL63 (33,2.13%),human enterovirus (32,2.06%),human parainfluenza 4(31,2.00%),human coronavirus-OC43 (30,1.93%),and human parainfluenza 2(11,0.71%).176 cases (11.35%) were detected as co-infection.The infection rate(56.07%) of under 5 years old group was higher than that of other groups.Conclusions The predominant respiratory viruses,who are responsible for acute upper respiratory tract infections in Hebei Province,are HRV,PIV3,RSV,ADV and IFV.Each virus possess the specific epidemiological feature.
ABSTRACT
Objective To investigate the effect of postremission consolidation therapy with intermedium-dose cytarabine (MDAC) in elderly patients with acute myelogenous leukemia (AML). Methods Clinical data of 61 elderly AML patients (except M3) in postremission who achieved complete remission (CR) in two period of remission induction program were retrospectively analyzed. Results There were 26 cases in MDAC group and 35 cases in standard-dose cytarabine (SDAC) group. In MDAC group and SDAC group, the relapse free survival (RFS) time were 42.7 months and 16.0 months respectively (P= 0.002), the overall survival (OS) time were 44.6 months and 18.2 months respectively (P= 0.004), and the cumulative relapse frequencies rates were 26.9 % (7/26) and 54.3 % (19/35) respectively (x 2= 4.567, P= 0.033). However, 3 years OS rate of the two groups were 23.1%(6/26) and 8.6%(3/35) (x 2=2.496, P=0.114) , and there was no significant difference in the incidence of adverse reactions between the two groups (all P > 0.05). Conclusion MDAC could improve RFS and OS for the elderly AML patients in postremission who received CR in the early stage, and the incidence of adverse reactions is similar to that of SDAC.
ABSTRACT
Objective To analyze the clinical features and prognosis of CD34-positive and CD34-negative adult patients with acute T-lymphoblastic leukemia (T-ALL),and to explore the value of CD34 expression for prognosis of patients with T-ALL.Methods 75 adult patients diagnosed with T-ALL from January 2012 to July 2015 in the Department of Hematology,the First Affiliated Hospital of Zhengzhou University,were analyzed retrospectively.According to the expression of CD34,the patients were divided into CD34-positive group and CD34-negative group,and then the clinical characteristics and prognosis of both groups were analyzed.Results In 75 patients,CD34-positive group had 24 (32.0 %) patients and CD34-negative group had 51 (68.0 %) patients.Between the two groups,there was no significant difference in these factors,such as sex,age,infiltration of liver,spleen and lymph nodes,thrombocytopenia,high white blood cell count,abnormal karyotype,complete remission within 4 weeks and central nervous system leukemia (CNSL).The proportions of patients with hemoglobin (Hb) < 90 g/L and expression of myeloid lineage marker were higher in the CD34-positive group than those in the CD34-negative group (x2 =5.888,P=0.015;x2 =10.758,P =0.001,respectively).There were only 18 patients treated with hematopoietic stem cell transplantation (HSCT),57 patients were not.In patients without HSCT,the median survival time in the CD34-positive group and CD34-negative group was significant different (5 months vs.32 months,x2 =9.172,P =0.002).Conclusions CD34 expression in adult patients with T-ALL appears to be associated with Hb < 90 g/L and the expression of myeloid lineage markers.For the patients without HSCT,CD34 is likely negatively related with the prognosis.
