OBJECTIVETo gain insight into the mechanism by which sex-determining region of Y chromosome (SRY)-related high-mobility-group box 2 (SOX2) involved in carcinogenesis and cancer stem cells (CSCs).

DATA SOURCESThe data used in this review were mainly published in English from 2000 to present obtained from PubMed. The search terms were "SOX2," "cancer," "tumor" or "CSCs."

STUDY SELECTIONArticles studying the mitochondria-related pathologic mechanism and treatment of glaucoma were selected and reviewed.

RESULTSSOX2, a transcription factor that is the key in maintaining pluripotent properties of stem cells, is a member of SRY-related high-mobility group domain proteins. SOX2 participates in many biological processes, such as modulation of cell proliferation, regulation of cell death signaling, cell apoptosis, and most importantly, tumor formation and development. Although SOX2 has been implicated in the biology of various tumors and CSCs, the findings are highly controversial, and information regarding the underlying mechanism remains limited. Moreover, the mechanism by which SOX2 involved in carcinogenesis and tumor progression is rather unclear yet.

CONCLUSIONSHere, we review the important biological functions of SOX2 in different tumors and CSCs, and the function of SOX2 signaling in the pathobiology of neoplasia, such as Wnt/β-catenin signaling pathway, Hippo signaling pathway, Survivin signaling pathway, PI3K/Akt signaling pathway, and so on. Targeting towards SOX2 may be an effective therapeutic strategy for cancer therapy.

OBJECTIVESTo investigate targeted blockage of BCR/ABL oncoprotein mediated cell transformation by STAT5 decoy oligodeoxynucleotide (ODN), its effect on the growth and proliferation inhibition of K562 cells and the related molecular mechanisms.

METHODSSTAT5 decoy ODN, designed and synthesized in vitro, was transfected into K562 cells by cationic lipid. The cell growth curve and colony formation assay were used to reflect the growth and proliferation capacity of K562 cells, RT-PCR to detect the expression of three genes downstream STAT5.

RESULTSConfocal microscopy demonstrated that STAT5 decoy ODN was successfully transfected into K562 cells (95.2% positive cells). STAT5 decoy ODN inhibited the growth of K562 cells (inhibition rate 77.7%) and their colony formation capacity (Decoy ODN treated group 8.3% vs control group 35.7%, P < 0.05) after the treatment with STAT5 decoy ODN, the expressions of c-myc, bcl-X(L), cyclin D1 mRNA were down-regulated by 15.4%, 30.8%, 29.1%, respectively in the K562 cells.

CONCLUSIONSSTAT5 decoy ODN inhibits the growth and proliferation of K562 cells. The mechanisms may be that decoy ODN blocks the transcriptional activation potent of STAT5 and down-regulates the expression of these tumor related genes downstream STAT5.

Objective To study the feasibility and clinical values of diffusion tensor tractography (DTT)in the spinal cord at 3.0 T MR.Methods Forty patients with spinal cord compression including cervical cord herniation and cervical spondylosis(30 cases),tumors in spinal canal(9 cases)and old injury in cervical vertebrae(1 cases)and 20 healthy volunteers participated in this study.Single-shot spin- echo echo-planar diffusion tensor sequence for tractography of the spinal cord was performed.The fibers of spinal cord were visualized by using fiber tracking software.Results On the DTT maps,the normal spinal cord was depicted as a fiber tract showing color-encoded cephaloeaudally,which indicated anisotropy in the cephalocaudal direction.By setting two ROI,the main spinal cord fiber tracts,such as corticospinal or spinothalamic tract,were visualized.The tracts from two sides of the brain did not completely cross.It was asymmetric in the number of tracts on the two sides in most normal subjects(8/10).The tracts of all patients with cord compression were seen oppressed or damaged in different degrees.The DrrT in patients with cervical spondylosis and extramedullary-intradural neurolemmoma demonstrated that tracts were oppressed but not damaged.The DTT in one ependymoma showed that tract was markedly compressed and slightly damaged.Conclusion DTT is a promising tool for demonstrating the spinal cord tracts and abnormalities,can provide useful information for the localization of compression and evaluation of the impairment extent on the white matter tracts of the spinal cord.

AIMTo investigate the changes of the spermatozoa ultrastructures before and after renal transplantation in uremic patients.

METHODSThe sperm of five uremic patients before and after transplantation and four healthy volunteers were collected and examined by scanning electron microscopy.

RESULTSAbnormal spermatozoa were found in patients pre-transplantation; abnormalities included deletion of the acrosome, absence of the postacrosomal and postnuclear ring, dumbbell-like changes of the head, tail curling, and absence of the mitochondrial sheath in the mid-segment. After renal transplantation, most of the spermatozoa became normal.

CONCLUSIONThere are many abnormalities with regard to the appearance and structure of the head, acrosome, mitochondria and tail of the spermatozoa in uremic patients. The majority of the spermatozoa returned to normal after renal transplantation, but a few still presented some abnormalities possibly relating to the administration of immunosuppressants.

Objective To study the differences in 24 h ambulatory blood pressure of healthy young men between the plateau and the plains.Methods A total of 100 young men were enrolled in this study.They underwent 24 h ambulatory blood pressure monitoring on the plateau and on the plains respectively.The data was analyzed by SPSS.17.Results The 24 h mean systolic blood pressure (24HMSBP) and diastolic blood pressure (24HMDBP),day (6:00-22:00) mean systolic blood pressure (DMSBP) and diastolic blood pressure (DMDBP),night (22:00-6:00) mean systolic blood pressure (NMSBP) and diastolic blood pressure (NMDBP),24 h mean heart rate (24MHR),HRmax,HRmin,24 h systolic blood pressure load (24HSBPL) and diastolic blood pressure load (24HDBPL),day (6:00-22:00) systolic blood pressure load (DSBPL) and diastolic blood pressure load (DDBPL),night (22:00-6:00) systolic blood pressure load (NSBPL) and diastolic blood pressure load (NDBPL) were significantly different between the plateau and plains (all P ＜ 0.05).However,the systolic blood pressure decrease rate (SBPDR) and the diastolic blood pressure decrease rate (DBPDR),day systolic blood pressure coefficient of variation (DSBPCV) and diastolic blood pressure coefficient of variation (DBPCV),night systolic blood pressure coefficient of variation (NSBPCV) and diastolic blood pressure coefficient of variation (NBPCV) were not significantly different (P ＞ 0.05).Conclusion The systolic blood pressure (SBP)and diastolic blood pressure (DBP) on the plateau are significantly higher than those on the plains.24HMDBP and DMDBP increase more significantly on the plateau than those of SBP.The blood pressure load (BPL) on the plateau is higher than that on the plains,with a higher degree of dispersion,so are the 24 h mean heart rate (24MHR),HRmax,and HRmin.

OBJECTIVESTo explore the category, quantity and clinical significance of autoantibodies on bone marrow hematopoietic cells in patients with immunorelated cytopenia and evaluate the sensitivity of direct antiglobulin reaction (Coombs test ) of bone marrow mononuclear cells (BMMNC).

METHODSThe category and the positive rate of autoantibodies on bone marrow hematopoietic stem cells, nucleated erythrocytes, granulocytes in 32 patients with uncertain immunorelated cytopenia were investigated by using BMMNC-Coombs test and double immunofluorescence flow cytometry.

RESULTSThe positive rate of autoantibodies on bone marrow hematopoietic cells tested by flow cytometry was 90.63% which was higher than that by BMMNC-Coombs test (50.0%) (p < 0.05). In 29 positive cases, IgG autoantibody accounted for 6.90%, IgM13.8%, IgG+IgA 3.4%, IgG+IgM 31.0%, and IgG+IgM+IgA 44.8%. Of the 29 Patients, 25 (86.2%) with IgG autoantibody, 26 (89.7%) with IgM and 14 (48.3%) with IgA. The patients with IgG autoantibody alone had the lowest hemoglobin levels, and those with IgM autoantibody might have intravascular hemolytic findings. The response time of patients with IgG and IgG+IgM was shorter than that of the other patients. 91.3% of the patients had autoantibodies on bone marrow hematopoietic stem cells and showed pancytopenia, and 50% of the patients had autoantibodies on nucleated erythrocytes and granulocytes. Eleven of 13 patients with negative BMMNC-Coombs tests had autoantibodies on bone marrow hematopoietic stem cells detected by FACS. There was no significant difference of the quantities of the three categories of autoantibodies of nucleated erythrocytes and stem cells. The quantities of IgA on granulocytes were lower than that of IgG and IgM. There was no significant difference between IgG and IgM on granulocytes. The quantity of IgA on hematopoietic stem cells was significantly higher than that on nucleated erythrocytes or granulocytes.

CONCLUSIONSThe sensitivity of double immunofluorescence flow cytometry assay was higher than that of BMMNC-Coombs test for detecting autoantibodies. In immunorelated cytopenia patients, the predominant autoantibody was IgM which could cause intravascular hemolysis, and the second one was IgG which could cause severe anemia. Most immunorelated cytopenia patients had autoantibodies on hematopoietic stem cells and showed pancytopenia. IgA was more easily seen on the hematopoietic stem cells.
