Lymphatic metastasis in breast cancer is the most frequent route of metastasis,which is one of most pirotal factors generated comparatively earlier in determining breast cancer staging and electing therapeutic regimen.Lymphangiogenesis is the foundation of lymphatic metastasis.The PI3K/AKT/VEGF-C signal transduction pathway may exist in breast cancer lymphangiogenesis,in which AKT phosphorylation promotes breast cancer lymphangiogenesis and lymphatic metastasis.This article mainly reviews the adjusted effects of AKT phosphorylation in breast cancer lymphatic metastasis.

Objective Two single nucleotide polymorphisms(SNPs)in TBX1 gene,G2857C(rs737868)and G2963A(rs28649236),were chosen to investigate their distribution in contruncal defects(CTD)patients and normal controls in order to determine the relationship between TBX1 gene and CTD.Methods By PCR-RFLP,genotypes of these two SNPs were analyzed in 100 patients with CTD and 100 normal controls during Mar.2004 to May.2006. 2 test was applied to analyze the genotype frequency and allele frequency between CTD groups and control groups.Results Remarkable significance were observed at G2963A between CTD groups and normal controls,the G allele frequency in CTD groups were much higher than that in normal controls(?2=5.30,P

Objective To investigate the relationship between miR-411 and breast cancer,and the expression of miR-411 and its effects and mechanism research on proliferation and metastasis in breast cancer.Methods Real-time polymerase chain reaction (RT-PCR) was used to detect the expression of miR411 in breast cancer cells and tissues.Methyl thiazolyl tetrazolium (MTT),clone formation assay and Transwell assay were used to detect the effect of miR-411 expression on the proliferation,migration and invasion in breast cancer cells.The effect of miR-411 on growth factor receptor-bound protein 2 (GRB2) expression in breast cancer cells was detected by RT-PCR and Western blot.The direct effect of miR-411 target on GRB2 was detected by dual luciferase reporter assay.MTT,clone formation assay and Transwell assay detect the effect of GRB2 expression on the proliferation and invasion in breast cancer cells.Detection the effect high expression of miR-411 on GRB2 downstream signaling pathway related molecules expression in breast cancer cell with Western blot.Results The expression of miR-411 in breast cancer tissues was significantly lower than that in adjacent non-cancerous tissues (P ＜ 0.05).The expression of miR-411 in breast cancer cells SK-BR-3,BT-549 and MDA-MB-231 was significantly lower (P ＜ 0.05).Compared to the negative control group,the transfection of miR-411 mimic inhibited the proliferation,migration and invasion of MDA-MB-231 breast cancer cells (P ＜ 0.05).Targetscan showed that miR-411 could bind to GRB2 3'UTR at position 741-747.Compared with the negative control group,GRB2 3'UTR wild-type plasmid and miR-411 co-transfection reduced the fluorescence activity (P ＜ 0.05).Transfection of siGRB2 significantly reduced the expression of GRB2 protein in MDA-MB-231 breast cancer cells (P ＜ 0.05).Compared to the negative control group,the inhibition of GRB2 expression reduced the proliferation and the number of colony formation of MDA-MB-231 breast cancer cells (P ＜ 0.05).Transwell assay showed that transfection of siGRB2 significantly reduced the number of invasive cells in MDA-MB-231 breast cancer cells (P ＜ 0.05).Conclusions miR-411 is related closely to the occurrence and development of breast cancer,miR-411-GRB2-Ras axis is expected to become a new target for biological treatment of breast cancer.

Objective To observe the relationship between hemoglobin (Hb) and vascular endothelial growth factor (VEGF) in serum of the patients with cancer. Methods Enzyme linked immunosorbent assay (ELISA) was used to detect VEGF levels in serum of the patients with cancers. Results The serum level of VEGF in the cancer group are significantly higher than that in the control group. The serum level of VEGF in patients with low level of hemoglobin ( 123.5 g/L) ( P

Objective To analyze expression of miR-324-5p in plasma of CHD patients by real-time PCR and identification of early diagnosis,for CHD.Methods In 2012 June to 2013 February 76 patients and 13 normal controls who were included in the study had measurement of plasma expression levels of miR-324-5p by real-time PCR.MedCalc 13.0 software were used for statistical analysis and comprehensive evaluation of miR-324-5p in CHD disease for diagnosis.Results Analysis of re-ceiver operating curve (ROC)showed that area under the curve (AUC)was 0.731 and best diagnostic threshold was 0.116 1.The sensitivity was 64.5% and specificity of 84.6%.Conclusion Circulating miR-324-5p as a biomarker for early diagno-sis of CHD has some-extent clinical value,but needs combined with other medical indicators.

Objective To investigate the development and dynamic changes of host immune response in DBA/2 mice infected with Plasmodium yoelii 17XL. Methods Female DBA/2 mice were infected by intraperitoneal ( i. p. ) injection of 106 P. yoelii 17XL parasitized erythrocytes ( PRBC). Levels of IL-12, IFN-γ, IL-4, IL-10 and P. yoelii 17XL-specific antibody in sera were measured by ELISA. Concentrations of NO in cell supernatants were measured by the Griess reaction. Parasitemia,percentage of mononuclear-macrophages of individual mice were monitored daily, and phagocytosis of mononuclear macrophages was also observed. Results Primary parasitemia in vein blood was developed on day 3 postinfection, which peaked with a level of 46. 9% on day 9. Most mice cleared the infection and survived by day 20 postinfection. From day 6 to day 16, the phagocytosis of PRBC by rodent macrophages was observed on the blood smear. Infected mice had a continuously increased level of IL-12 in serum from day 1 postinfection. Accordingly, high level of IFN-γ was also detected in sera from day 1 postinfection,which peaked on day 6. Infected mice produced higher level of IL-4 and IL-10 in serum on day 6 postinfection, which peaked on day 9 and day 15 postinfection respectively. In addition, splenocytes from infected mice produced significantly higher level of NO on day 6 and 20 postinfection. Level of P. yoelii 17XL-specific IgG was determined in the sera of infected mice with a steadily increased trend after infection, which peaked on day 70 postinfection. Conclusions Effective polarizing of Thl cells is significant in inhibition of parasitemia and eventual clearance of the Plasmodium parasites. Activated mononuclear-macrophages play a key role in inhibiting parasitemia in the early phase of infection with P. yoelii 17XL.

Objective To investigate the posttraumatic stress disorder(PTSD) and ethical decision-making in nurses suffered workplace violence, and analyze the relmionship between them. Methods Totally 340 nurses suffered workplace violence were questionnaired by the PTSD Scale and the Ethical Decision- making Scale. Results The incidence rate of PTSD was 17.06%(58/340), the total score of PTSD was (38.77± 13.57).The scores of ideal ethical practice, actual ethical practice and ethical decision- making in the PTSD group were 121.36±8.33, 105.56±7.76, 226.92±15.52, and were significantly lower than that in the non-PTSD group (140.60±9.01, 117.65±8.41, 258.27±16.73) (t=-14.996, -10.015, -13.153, P < 0.01). The score of PTSD was negtively correlated with the scores of ideal ethical practice, actual ethical practice and ethical decision- making (r=-0.415, -0.431,-0.420, P < 0.05). Conclusions The PTSD probably occurred after workplace violence, nursing administrators should pay close attention to the PTSD and therefore improve nurses′ethical decision-making.

Objective The aim of this study was to investigate which inflammatory markers allow an accurate differentiation of septic and gouty arthritis.Methods In 2013 January to 2014 January 33 patients with septic arthritis and 29 patients with gouty arthritis.Detected white blood cells,C-reactive protein and uric acid of inflammatory markers in plasma and tested lac-tate,glucose,uric acid,lactate dehydrogenase and white blood cell count inflammatory markers in the synovial fluid.MedCalc 13.0 software were used for statistical analysis.Results There were no significantly different between serum C-reaction protein and WBC counts with two groups.Synovial lactate showed the greatest diagnostic potential (AUC=0.898,sensitivi-ty=96.9%,specificity=72.4%)followed by serum uric acid (AUC=0.818)and synovial uric acid (AUC=0.808).Con-clusion Lactate in the synovial fluid has excellent diagnostic potential to differ septic arthritis from gouty arthritis.Synovial lactate levers above 1.7 mmol/L almost proofed septic arthritis.
