Objective To explore the correlation between verbal memory and working memory in patients with alcohol dependence (AD).Methods A total of 40 patients with AD and 40 health controls were included in this study.N-back task was used to evaluate the verbal working memory.20 sets of phrases were used to evaluate long-term verbal memory.Results Correct number of verbal memory in AD group ((5.15±0.92)times) was lower than that of HC group ((7.35±3.07) times) after one-week baseline test,and the difference was statistically significant (t=4.344,P＜ 0.01).Compared with HC group ((1 436.37±192.50) ms,(1.08±0.89) times,(4.00±0.85) times,respectively),AD group((1 535.40± 192.50) ms,(1.90± 1.57)times,(2.60± 1.39)times) showed significantly impaired reply reaction time of 2-back,error number of 1-back and 2-back (t=-2.112,P=0.038;t=-2.899,P=0.005;t=-5.433,P＜0.01).The error number of 2-back task in AD group was negative correlated with verbal memory after one-week baseline test (r=-0.427,P=0.006).Conclusion The verbal memory is impaired in AD patients.Long-term verbal memory damage have a certain correlation with working memory.

Objective To investigate the expression of Notch4 protein and to analyze its correlation with the clinical parameters and the microvessel dentisty in renal cell carcinoma. Methods The expression of Notch4 was examined in 60 cases of renal cell carcinoma and the para-carcinoma tissue by SP immunohistochemical stain-ing ,and CD34 detection was used for counting microvessel density. Statistical analysis was performed to reveal the correlation with clinicopathological parameters ,microvessel density and prognosis. Results The positive rate of Notch4 protein expression was 75%(45/60)in para-carcinoma tissue,and was 43.3%(26/60)in renal cell car-cinoma,with significant difference on tumor grade and Lymph node metastasis(P<0.05). The microvessel densi-ty in Notch4 positive tissues was significant lower than that in the negative samples(P<0.05). The survival time of patients with Notch4 positive expression was significantly longer than that of patients with Notch4 negative expres-sion(P<0.05). Conclusion Notch4 protein plays an important role in the development of renal cell carcinoma. Notch4 expression might both attenuate the malignant biological characteristics and suppress the angiogenesis dur-ing tumor development.

ObjectiveTo explore the clinical significance of fms-like tyrosine kinase3(FLT3) expression in evaluation prognosis of acute myeloid leukemia(AML) prognosis.Methods50 patients with AML were selected.AML patients with normal karyotype were 20 cases,the abnormal karyotype were 30 cases.3ml bone marrow before themotherapy was aspirated respectively,and the FLT3 gene expression in leukemia cells was detected with polyenzyme chain react(PCR).ResultsThe FLT3 expression rate in AML patients with normal karyotype was 5.0％,and was 26.7％ in AML patients with abnormal karyotype,33.3％ in AML patients with refractory-relapse,and 4.5％ in AML patients with continue remission.The FLT3 expression rate was related with high leukemia cells percentage in bone marrow and high blood cells count in peripheral blood,and was not related with Franch America British(FAB) classification.The free-disease survival(FDS) and overall survived(OS) was shorter in FLT3 expression AML patients than that in no FLT3 expression AML patients.There was a statistical significance between the former and the latter( x2 =4.17,P ＜0.05 ).Conclusion FLT3 was a kind of worse factor in AML patients prognosis,and could guide clinical individual treatment in AML.

Objective To explore the relationship of cell proliferation of acute leukemia stimulated by granulocyte colony-stimulating factor(G-CSF) and the expression of granulocyte colony stimulating factors receptor(G-CSFR).Methods Thirty cases of initial and refractory-relapse acute myeloid leukaemia(AML) patients,20 cases of acute lymphoblastic leukemia(ALL) and 20 normal controls were involved in the study.The 5ml bone marrow was taken from each patient before chemotherapy and the marrow mononuclear cells(MNC) were cultured with 5,10,15,20 and 25 ng/ml G-CSF respectively.After 24h,the DNA diploid and the expressions of G-CSFR and CD34 were detected by flow cytometry(FCM).Results The DNA diploid of MNC from AML was increased with the elevated concentration of G-CSF after 24h,and that of the ALL and normal control did not change significantly.The expression rates of G-CSFR were(68.59?13.99)%,(1.90?0.93)% and(70.5?10.8)% in AML,ALL and the normal control respectively.The expression rates of CD34 were(45.15?4.22)%,(46.75?3.15)% and(3.15?0.22)% in AML,ALL and normal control respectively.The expression of G-CSFR in AML was significantly different from that of ALL(P0.05).The expression of G-CSFR in ALL was significantly different from that of the normal control(P

Objective To analyze and study the diagnosis of large granular lymphocyte leukemia(LGLL).Methods To report and discuss six cases weth LGLL we have found. Results 2 of T-LGLL and lof NK-LGLL had indolent process, mainly presenting with anemia and splenomegaly and good response to treatment, while; 1 of T-LGLL and 2 of NK-LGLL had aggressive process, their clinical characters are obviously general symptom, hepatomegaly,splenomegaly,these disease develop quickly and have bad prognosis. The immunophenotype of indolent LGLL is distinct from aggressive cases. Conclusion As a group of heterogeneous disease,its diagnosis should be based on clinical manifestation and immunophenotype and differentiated it carefully.

Objective To investigate the clinical and laboratory diagnosis of adult hemophagocytic syn-drome (HPS) . Methods Clinical data of 24 patients with HPS from 2000 to 2008 were retrospectively analyzed. Results Of the 24 HPS cases, 12 had a malignant associated hemophagocytic syndrome (MHAS), and 10 were fi-nally diagnosed by bone marrow immunohistochemist ;Of 12 cases in non-MAHS group,4 were with virus associated hemophagocytic syndrome (VAHS), and 4 were of the other infections, whereas 4 patients diagnosed of immune associated HS (MAS). There were significant difference in onset age, mortality, serum lactate dehydrogenase (LDH) and serum ferritin(FER) and neutrophilic NAP between non-MAHS group and MAHS group(P <0.01 ,P<0.05). In all cases bone marrow biopsy showed significant differences in cytological and pathological features between MAHS group and non-MAHS group. Conclusion Etiology,immunology,and bone marrow cell biopsy and pathology as well contribute to the diagnosis and typing of HPS and will give a guide to the therapy.

Objective: To investigate the role of PRDM1 gene inactivaion in the regulation of C-MYC in diffuse large B-cell lymphoma (DLBCL), and to explore the correlation of its immunophenotype and prognosis. Methods: 100 cases paraffin-embedded DLBCL tissues were collected from January 2009 to December 2015 at the First Affiliated Hospital of Xinjiang Medical University along with 20 cases of reactive proliferative lymph nodes as control. Immunohistochemical methods were used to detect the expression of CD20, CD10, MUM1, Ki-67, bcl-6, PRDM1/Blimp1, C-MYC and PAX5 protein. The tumors were classified into two subtypes according to Hans classification.The expression of PRDM1 and C-MYC gene in tumor group and control group was detected by reverse transcription PCR (RT-PCR) and the relationship between PRDM1 and C-MYC gene was analyzed.OCI-LY1 (GCB subtype) and OCI-LY3 (non-GCB subtype) cell lines were transfected with small interfering RNA by cationic liposome reagent transfection, and the expression of C-MYC in the transfected cell lines was detected by RT-PCR and Western blot. The Kaplan-Meier method was used to analyze the prognostic significance of PRDM1/Blimp1 and C-MYC at protein and mRNA levels. Results: There were 27 cases of GCB subtype and 73 cases of non-GCB subtype according to Hans classification. The positive expression of Blimp1 in DLBCL group and proliferative lymph nodes in control group was seen in 26(26.0%) and 20 cases(100%), respectively. There were 58 cases with high expression of PRDM1 at mRNA level, including 22 cases of GCB subtype and 36 cases non-GCB subtype, and the difference was statistically significant (P=0.004). There were differences in PRDM1 gene expression between the two immunological subtypes, serum lactate dehydrogenase (serum LDH) level, presence of B symptoms, tumor primary sites and other clinical pathological parameters, while C-MYC expression was different in gender, IPI score, and serum LDH levels. Upon PRDM1/Blimp1 gene silencing in the two cell lines, C-MYC protein and gene expression were up-regulated in the transfection group, compared with the blank control group and negative control group by reverse transcription PCR and Western blot analyses. Moreover, PRDM1 expression was significantly associated with C-MYC(χ²=7.648, P=0.006) at mRNA level. Conclusion The up-regulation of C-MYC gene expression induced by PRDM1 inactivation in DLBCL may play an important role for the development of DLBCL.PRDM1 protein and mRNA are associated with immunophenotyping and PRDM1 mRNA is a marker of poor prognosis.

Objective: To compare different specimen types of lung adenocarcinoma in the detection of epidermal growth factor receptor (EGFR) gene and to correlate EGFR mutations with patient clinical features. Methods: One hundred lung adenocarcinoma cases were collected from June to December in 2015, at the First Affiliated Hospital of Xinjiang Medical University.Of the 100 lung adenocarcinoma samples, 43 were male and 57 were female. The age was from 40 to 88 years old, and the average age was 66 years. One hundred lung adenocarcinoma cases were divided equally into two groups. Mutation analysis of EGFR gene by real-time PCR was performed using biopsied tissue and paired blood samples in one group (n=50) and using pleural effusion and paired blood samples in the other group (n=50). Results: The mutation rate of EGFR gene in biopsy samples was 54% (27/50) , higher than that of blood samples (46%, 23/50), but without statistical differences (χ²=0.640, P=0.424). In contrast, mutation rate of EGFR gene in pleural effusion samples (42%, 21/50) was higher than that of blood samples (34%, 17/50), but without statistical differences(χ²=0.679, P=0.409). Two patients had EGFR mutation detected in paired blood samples but not in the corresponding biopsy samples, and four patients had EGFR mutation detected in pleural effusion samples but not in their paired blood samples. The mean progression-free survival of patients with detectable EGFR mutation were 9.5 months (tissue samples), 8.6 months (pleural effusion) and 8.5 months (blood). However, there was no statistical difference. Conclusions Blood samples may be used to assess EGFR mutations for patients with lung adenocarcinoma. However, further studies are needed to improve the sensitivity and accuracy in the detection of EGFR mutations using blood samples.

Objective To investigate the changes of hemodynamics and cardiac function in pediatric living donor liver transplantation (LDLT).Methods 50 cases of pediatric living donor liver transplantation in our hospital from January 2016 to January 2017 were collected.The hemodynamics was monitored by Mostcare with the radial artery.Acquisition of heart rate (HR),mean arterial pressure (MAP),peripheral vascular resistance index (SVR/SVRI),stroke volume / stroke index (SV/SVI),cardiac output (CO/CI),cardiac index / stroke volume variability (SVV),dp/dtmax (cardiac contractility),cardiac cycle efficiency (CCE) at the moment of the start of operation(T0),before occlusion of the inferior vena cava (T1),immediately after occlusion of the inferior vena cava (T2),anhepatic phase 30 min (T3),immediately after reperfusion(T4),neohepatic phase 5 min (T5),30 min (T6) and 60 min (T7).Results There were no significantly hemodynamic fluctuations before occlusion of the portal vein.At T3,the increased of MAP,CI,SVRI (T3 vs T0,P＜0.05),while CCE decreased significantly (T3 vs T0,P＜0.05);MAP,SVRI,lower HR,CI and dp/dtmax have different degrees of liver T4,but the change was not significant.SVV fluctuated in the anhepatic phase at 11％ ～ 15％,maintained in the new liver stage at 12％ ～ 15％,but fluctuated slightly.Conclusion Mostcare can be used to monitor the hemodynamic and cardiac function changes in pediatric living donor liver transplantation,but the reasons for the change of the monitoring indicators and the significance of guiding the perioperative treatment need to be further studied.
