    Objective · To study the correlation between KRAS, NRAS and BRAF mutations and the clinicopathological features in patients with colorectal cancer (CRC). Methods · The 461 paraffin-embedded CRC tissues were collected. The mutations in hotspot region of KRAS, NRAS and BRAF genes were investigated using amplification refractory mutation system. The relationship between the mutation rates of each gene and the clinicopathological characteristics in CRC patients were analyzed. The KRAS and BRAF mutation profile and the impact on promoter methylation of the downstream genes were further investigated in both CRC tissues and cell lines through literatures and the American Type Culture Collection. Results · KRAS, NRAS and BRAF mutation rates in CRC tissues were 44.0%, 6.1% and 5.2%, respectively. KRAS mutations in the right colon were remarkably higher than the left colon (P=0.000). NRAS mutations were more likely to occur in male patients than female patients (P=0.002). BRAF mutation was closely correlated with age, tumor differentiation, tumor location and nerve invasion, but was exclusive of 203 KRAS mutated samples. Conclusion · KRAS, NRAS and BRAF mutations were significantly correlated with the clinicopathological features of CRC, and the mutation incompatibility was observed between KRAS and BRAF genes.

    Abstract579)      PDF(pc) (10617KB)(828)       Save
    Objective · To test the application of flow cytometry technique to detect the redox status with genetically encoded fluorescent probe roGFP2, to
    compare it with laser scanning confocal microscope (LSCM), and to demonstrate the diversity of cellular redox status in HeLa and Panc-1 cell populations.
    Methods · Time lapse imaging with LSCM was performed in single cell transfected with roGFP2 probe to detect the dynamic changes of 405 nm/488 nm
    ratio (405/488 ratio). Flowcytometry technique was also performed in HeLa cells transfected with roGFP2 probe to detect the dynamic alterations of
    405/488 ratio. The global cell population was analyzed and the subpopulations of different redox status were dissected. Flowcytometry technique was
    further applied in Panc-1 cells with different CD24 or CD44 marker to detect the dynamic alterations of 405/488 ratio of roGFP2 and identify the different
    redox status. Results · Time lapse imaging with LSCM showed that 405/488 ratio of roGFP2 dramatically changed in response to H2O2 in dose and time
    dependent manner at a single cell level. When dozens of cells were chosen, the average ratio showed increased and dynamic trend. Compared to LSCM,
    flow cytometry could detect the average of 405/488 ratio of roGFP2 as well. Meanwhile, with the application of flow cytometry the cell population can be
    divided into three subpopulations based on 405/488 ratios, most in oxidized and medium redox status, few in reduced status. Using flow cytometry, CD24+/
    CD44+ Panc-1 cells, pancreatic cancer stem cells, can be found to have overall lower 405/488 ratio and more percentage of subpopulation of reduced status under resting and stress condition. Conclusion · Flow cytometry technique can be applied to detect roGFP2 and has advantage in application to show the overall as well as diverse redox status in cell population. Flow cytometry detection of cellular redox status with genetically encoded probe can be a useful
    tool in tumor cell biology and developmental biology research.

       2018, 38 (1): 18-.   DOI: 10.3969/j.issn.1674-8115.2018.01.004
    Abstract646)      PDF(pc) (7691KB)(685)       Save
    Objective · To investigate the biological effect and mechanism of OTUD7B in acute myeloid leukemia (AML) cells. Methods · The expression
    of OTUD7B in peripheral blood mononuclear cells and bone marrow mononuclear cells of AML patients were detected. The relationship between OTUD7B
    and survival of AML patients was confirmed by using TCGA database. Mouse model of M2 type AML was established, and the expression of OTUD7B in
    the bone marrow, spleen and liver of the mice was detected. OTUD7B was overexpressed in AML cell lines HL60 and kasumi1, then the cell viability and
    cell cycle were measured. The AKT/mTOR pathway proteins were detected after OTUD7B overexpressed and then the cell growth inhibition was detected
    after overexpression of AKT1. Results · The expression of OTUD7B was lower in primary leukemia cells from all types of AML patients and in the bone
    marrow, liver and spleen of M2 type AML mice, which was closely related to the survival time of AML patients. OTUD7B overexpression in HL60 and
    kasumi1 cells significantly inhibited the cell viability and decreased the percentage of S phase cells. OTUD7B significantly inhibited the phosphorylation of
    AKT and mTOR, and AKT1 overexpression partially reversed the inhibitory effect of OTUD7B on cell growth. Conclusion · OTUD7B expression is low in
    primary leukemia cells from AML patients and in bone marrow, liver and spleen of the M2 type AML mice. The survival time of patients with low OTUD7B
    expression is shorter. Overexpression of OTUD7B significantly inhibited the cell viability of HL60 and kasumi1 cells and the entry of cells into S phase. The
    inhibitory effect of OTUD7B overexpression on AML cells might be related to the inhibition of AKT / mTOR signaling pathway.

    Objective · To investigate the bacteriostasis effect of Mycobacterium tuberculosis (MTB) polyphosphate kinase 2 (PPK2) aptamer on MTB
    in vitro. Methods · The bioinformatics method was used to analyze the homology of MTB PPK2 and common pathogens of respiratory tract, and the
    PPK2 phylogenetic tree was constructed. The binding affinity of the PPK2 aptamer to H37Rv, BCG, Mycobacterium smegmatis, Pseudomonas aeruginosa
    and Acinetobacter baumannii was analyzed by enzyme-linked oligonucleotide assay (ELONA). The PPK2 aptamer was incubated for 24 h in serum
    and its biological stability in serum was analyzed by agarose gel electrophoresis. The minimum inhibitory concentration (MIC) of the PPK2 aptamer to
    H37Rv was determined by micro-azure method. H37Rv was inoculated with 1 μmol/L PPK2 aptamer or random sequence on Roche culture medium for
    10 d and colony growth status was observed. H37Rv was co-cultured with different concentrations of PPK2 aptamer for 10 d, absorbance at 600 nm was
    measured by microplate reader. The effect of PPK2 aptamer on the growth of H37Rv was observed. Results · PPK2 phylogenetic tree constructed by
    bioinformatics analysis showed that PPK2 protein of H37Rv was not closely related to the common pathogens of respiratory tract, and it was relatively
    close to Pseudomonas aeruginosa. The ELONA assay results showed that the PPK2 aptamer binded selectively to H37Rv. Agarose gel electrophoresis
    analysis showed PPK2 aptamer in serum was at least stable for 8 h. The MIC of the PPK2 aptamer to H37Rv was 50 nmol/L. The colony growth of Roche
    culture showed that PPK2 aptamer had an inhibitory effect on H37Rv growth. Growth inhibition test showed that the absorbance at 600 nm of H37Rv
    showed a decreasing trend with the increase of PPK2 aptamer concentration, which indicated that PPK2 aptamer had an inhibitory effect on H37Rv growth.
    Conclusion · PPK2 aptamer has good antibacterial activity against H37Rv in vitro.

    Atherosclerosis is an immune-mediated inflammatory disease of the arterial wall, with both the innate and adaptive immune systems responding to many endogenous and exogenous antigens. Both proatherogenic as well as atheroprotective roles have been identified for the immune system in atherosclerosis. Hence, it is conceivable that an immuno-modulatory strategy via active immunization against many of these antigens could potentially alter the natural history of atherosclerosis. Cholesterol ester transfer protein (CETP) plays an important role in lipid metabolism, suggesting it might prevent atherosclerosis. This review discusses the recent advances of vaccine targeting the development of atherosclerosis, mainly about the CETP targeting vaccines.

    The neuromyelitis optica spectrum disorders (NMOSD) are a spectrum of central nervous system autoimmune diseases caused by humoralmediated immunity. NMOSD is characterized by specific expression of aquaporin-4 (AQP-4) antibody and involvement of optic nerve and spinal cord. However, the expression level of AQP-4 antibody is not directly proportional to disease activity and recurrence rate, suggesting that multiple mechanisms have been involved in mediating the process of disease. Many evidences of clinical and basic experiments indicated that B lymphocytes play an important role in the pathogenesis of NMOSD. This paper mainly summarized the role of B lymphocytes in the pathogenesis of NMOSD, including aspects of antigen presentation, humoral immunity, regulatory B cell effect and B cell immune tolerance.

Clinical measures of the outcomes were measuredtranscutaneous oxygen saturation (TcSO2), hemoglobin at different periods, left heart function within 72 h, cranial ultrasound, transcutaneous bilirubin, the total time of phototherapy. Results · Hemoglobin values were significantly higher in the experiment group than those in the control group in vein at the first time (P0.008). Hemoglobin values were significantly higher in the experiment group than those in the control group 3-5 d, 8-11 d, and 14-18 d after birth (P<0.05). Four months after birth, hemoglobin in the experiment group was higher than that in the control group, but there was no significant difference (P0.075). There was no significant difference in the total time of phototherapy between the two groups (P0.849). There were no significant differences between the two groups on left ventricular ejection fraction and left ventricular short axis shortening score 72 h after birth (P>0.05). Conclusion · Umbilical cord milking can increase the hemoglobin level to premature infants and reduce the incidence of anemia at discharge, and it does not increase the risk of cardiac insufficiency and hyperbilirubinemia. This practice has been shown to be simple and safe.

    Objective · To assess the level of serum lipid metabolism related hormones in the patients of obstructive sleep apnoea hypoxia syndrome (OSAHS) combine with non-alcoholic fatty liver disease (NAFLD), and explore the potential role in the pathogenesis. Methods · Patients that main complaint for snoring were selected. According to polysomnography and NAFLD screening, the patients were divided as follows: OSAHS+NAFLD group, OSAHS group, NAFLD group, and control group, and the levels of serum lipid metabolism related hormones were measured. The patients with OSAHS were divided into three groups, i.e., mild, moderate and severe groups according to the degree of apnea hypopnea index (AHI) and minimal oxyhemoglobin saturation (MinSaO2) respectively. The statistical analysis about the morbidity of NAFLD in the patients with different OSAHS severity were analyzed. Multiple regression analysis was used to determine the independent predictors of NAFLD. Results · Significant differences were found in AHI, MinSaO2, the duration of hemoglobin desaturation (TSaO2<90%), body mass index, adiponectin, leptin, high sensitive C reactive protein and lipopolysaccharide (P<0.05 for all) among the groups of OSAHS, NAFLD and OSAHS+NAFLD. The morbidity of NAFLD exited statistical difference in the patients with different OSAHS severity (17.0%, 51.6% and 97.2%, P0.006), and the same trend was seen in the patients with different MinSaO2 severity (18.2%, 57.1% and 91.9%, P0.011). Multiple regression analysis showed that body mass index, AHI and adiponectin were independent predictors of the morbidity of NAFLD (P0.006,P0.020 and P0.008). Conclusion · The morbidity of NAFLD increases with the worsening of OSAHS. There is positive correlation between the severity and the level of serum adiponectin and leptin in the patients with OSAHS and NAFLD.
