OBJECTIVETo investigate the expression of nuclear export factor CRM1, Ser10-phosphorylated p27 and p27 in human gliomas.

METHODSThe expression of CRM1, Ser10-phosphorylated p27 and p27 were investigated in 70 cases of human gliomas and 10 specimens of the normal brain tissue by immunohistochemical technique and Western blot.

RESULTSThere were significant differences on the expression levels of CRM1, Ser10-phosphorylated p27 and p27 among normal brain tissue, gliomas of grades II and gliomas of grades III plus IV (P < 0.01). The expression of CRM1 in gliomas was inversely correlated with the expression of p27 (r(s) = -0.727, P < 0.01) and positively correlated with the expression of Ser10-phosphorylated p27 (r(s) = 0.954, P < 0.01) and Ki-67 (r(s) = 0.799, P < 0.01). Moreover, the expression of Ser10-phosphorylated p27 was inversely correlated with p27 (r(s) = -0.744, P < 0.01) and positively correlated with Ki-67 (r(s) = 0.785, P < 0.01).

CONCLUSIONSCRM1, through recognizing and binding with Ser10-phosphorylated p27, may promote moving of p27CRM1 from its original locating sites; act as a critical signaling component in the proliferative process of glioma cells and then, plays an important role in the development of gliomas.

OBJECTIVETo investigate the relationship of FGA gene 128C/G polymorphism and cerebral infarction (CI) and evaluate the effect of FGA-128C/G polymorphism on plasma fibrinogen in Hunan Hans.

METHODSFGA-128C/G polymorphism was detected by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) and DNA sequencing in 194 CI patients and 114 healthy controls.

RESULTSThere were CG and CC genotypes in the FGA-128C/G locus. No GG genotype was observed in Hunan Hans. There was no significant difference in genotype and allele frequencies between the controls and CI group (P> 0.05), and statistically significant difference was not found in fibrinogen (Fg) level between the CG and CC genotypes (P>0.05). After analyzing blood plasma Fg using the influencing factor multiple regression analysis, it was shown that the Fg level had no relationship with the FGA-128C/G genotype, but it increased with age. And the Fg level in males was higher than that in females.

CONCLUSIONThere was FGA gene 128C/G polymorphism in the Hunan Han population. There was no association of this polymorphism with the increased Fg level of CI patient in the population. FGA-128C/G might not be the predisposing gene of CI in Hunan Han population. The age and sex were the major factors affecting the plasma Fg level in this population.

OBJECTIVE: To establish immortalized embryonic fibroblast lines in heat shock transcription factor 1 (HSF1) HSF1-/- and HSF1+/+ mice and to provide experimental models to study the function of HSF1. METHODS: A mammalian expression vector (pSV3neo) containing the SV40 large T antigen was used to transfect the HSF1-/- and HSF1+/+ mouse embryonic fibroblast using Lipofectamine 2000. Colonies were screened by G418 and expanded to immortalized cell lines. PCR was used to detect the integration of the large T antigen with genome in the mouse embryonic fibroblast. Expression of SV40 large T antigen gene in expanded cells was identified by RT-PCR. HSP70 expression was examined by Western blot in the embryonic fibroblast lines. RESULTS: The stable growth and serial propagation were observed in the HSF1-/- and HSF1+/+ cell lines for six months. The mRNA of SV40 T antigen gene expressed in the two cell lines. HSP70 expression could not be induced in the heat-treated HSF1-/- mouse embryo fibroblasts. CONCLUSION The immortalized cells of HSF1+/+ and HSF1-/- mouse embryo fibroblasts are successfully established.

Liver cancer remains a challenge of global health, being the 4th leading cause of cancer death worldwide. Hepatocellular carcinoma (HCC) is the most common type of primary liver cancer, and is usually precipitated by chronic viral infections (hepatitis B and C), non-alcoholic steatohepatitis, heavy alcohol use, and other factors which may lead to chronic inflammation and cirrhosis of the liver. There have been significant advances in the systemic treatment options for HCC over the past decades, with several approvals of both immune checkpoint inhibitors and tyrosine kinase inhibitors in patients with preserved liver function. These advances have led to improvement in survival outcomes, with expected survival of greater than 18 months, in those with sensitive tumors, adequate liver function, and those functionally fit to receive sequential therapies. Several ongoing and promising trials are now evaluating combinational strategies with novel systemic agents and combinations of systemic therapy with locoregional therapy. In view of these trials, further advances in the treatment of HCC are foreseen in the near future.

Objective To explore the effects of exercise on dentate gyrus (DG) neurogenesis and the ability of learning and memory in hippocampus-lesioned adult rats. Methods Hippocampus lesion was produced by intrahippocampal microinjection of kainic acid (KA). Bromodeoxyuridine (BrdU) was used to label dividing cells. Y maze test was used to evaluate the ability of learning and memory. Exercise was conducted in the form of forced running in a motor-driven running wheel. The speed of wheel revolution was regulated at 3 kinds of intensity: lightly running, moderately running, or heavily running. Results Hippocampus lesion could increase the number of BrdU-labeled DG cells, moderately running after lesion could further enhance the number of BrdU-labeled cells and decrease the error number (EN) in Y maze test, while neither lightly running, nor heavily running had such effects. There was a negative correlation between the number of DG BrdU-labeled cells and the EN in the Y maze test after running. Conclusion Moderate exercise could enhance the DG neurogenesis and ameliorate the ability of learning and memory in hippocampus-lesioned rats.

OBJECTIVE: To study the potential significance and clinical application of FGFR1 gene abnormality in the diagnosis, clinical features, pathological mechanism and treatment in hematological tumors. METHODS: Clinical data of total of 29 patient with chromosome of 8 short arm (8P) abnormality who had more comprehensive medical history from 2013 to 2018 were collected. The karyotype analysis of bone marrow chromosomes in patients was carried out by using chromosome R band banding technique. FGFR1 gene was detected by using fluorescence in situ hybridization (FISH). RESULTS: Seven cases of FGFR1 gene abnormalities were decteted, including 3 cases of FGFR1 gene amplification, 2 cases of translocation, and 2 cases of deletion. Five patients with FGFR1 gene amplification or deletion not accompaned with eosinophilia, moreover the chromosome was a complex karyotype with poor prognosis; Two cases of FGFR1 gene translocation were non-complex chromosomal translocation and one of which survived for 6 years after bone marrow transplantation, the other chromosome karyotype showed no rearrangement of 8 short arm. However, FGFR1 gene rearrangement was confirmed by FISH analysis, which was a rare insertional translocation. CONCLUSION FGFR1 gene amplification or deletion often occur in cases with complex karyotype, which not accompany eosinophilia, moreover have poor prognosis. The patients with FGFR1 gene translocation accompany eosinophilia which is consistent with the clinical characteristics of myeloid / lymphoid neoplasms with FGFR1 abnormality. Karyotype analysis combined with FISH method can improve the detection of abnormal clones.

OBJECTIVE: To explore the clinical features and therapeutic efficacy in adult ALL patients with t (1; 19) (E2A-PBX1). METHODS: The clinic data of 19 adult ALL patients with t (1; 19) (E2A-PBX1) in our hospital from Nov. 22, 2010 to Apr. 4, 2018 were collected. The clinical features,complete remission (CR) rate, overall survival (OS) rate and relapse-free survival (RFS) rate of patients received chemotherapy and chemotherapy+HSCT were analyzed. RESULTS: In all the 19 patients, the median age was 24 (14-66), median WBC count was 16.47×109 (1.8-170.34)/L, median Hb level was 98 (65-176) g/L, median Plt count was 50 (15-254)×109/L. Pre B-ALL were 17 cases (89.5%), and common B-ALL were 2 cases (10.5%). Patients received the induction therapy, the overall CR rate was 94.7%, one course CR rate was 94.7%, 4 year OS rate was 47.1% and RFS rate was 43.3%. The OS rate and RFS rate of patients received transplantation were slightly higher than those of patients not received transplantation (OS: 62.5% vs 36.7%) (P=0.188)；RFS (62.5% vs 38.9%) (P=0.166). CONCLUSION Most adult ALL patients with t (1; 19) (E2A-PBX1) is Pre B-ALL by Immunophenotyping, as compared with the pediatric patients, the therapeutic efficacy for adult patients with t (1; 19) (E2A-PBX1) is worsen, therefore, stem cell transplantation is still acquired for better long term survival.
