ABSTRACT
Objective To investigate the correlation between IL‐18 and deep venous thrombosis disease and its clinical significa‐tion .Methods To detect the expression of IL‐18 by ELISA ,we collected the blood samples of DVT patients as the experimental group(n=40) compared to the control group(n=40) and normal group(n=20) .IL‐18 over expression/interference vectors were constructed and transfected human vein endothelial cells ,analyzed by microarray and KEGG Pathway as biology information tech‐nology .Then discuss the association between IL‐18 and DVT .Results Results of ELISA showed that compared with control group and normal group ,the expression of IL‐18 gene in DVT patient were up‐regulated(F=11 .248 ,P0 .05) .Immunofluorescence detected IL‐18 gene expression in cytoplasm of human umbilical vein endothelial cells (HUVECs) .According to the microarray analysis we found in the IL18‐pCDH‐GFP transfected cells 17 signaling pathways were down‐expressed while 16 signaling pathways were up‐expressed .Compared with normal group cells ,in the IL18‐LMP‐shRNAmir1 transfected cells 23 signaling pathways were down‐ex‐pressed and 9 signaling pathways were up‐expressed .Conclusion Based on the above experimental data ,it is very clear that IL‐18 influenced HUVECs and plays an important role in DVT ,it is possible to predict the diagnosis of DVT and act as candidate molecu‐lar markers .
ABSTRACT
Objective:To define the role of lymph tracers in lymph node dissection and pathological examination of papillary thyroid carcinoma. Methods:Patients with papillary thyroid carcinoma who met inclusion criteria were enrolled and randomly assigned into the three groups, namely, carbon nanoparticle (CN), methylene blue (MB), and conventional surgery (CS) groups. The number of detected lymph nodes in each group was summed, and pathological examination was conducted. Histological examination of the lymph node specimens in the tracer group was performed based on the classification of staining and nonstaining groups. Results:Major complications such as anaphylaxis did not occur after injection of CN and MB. The average of the detected lymph nodes was higher in the tracer group than in the CS group, and the detection rate of the lymph node was higher in the CN group than in the MB group. In addition, the rate of cancer metastasis was higher in the group with stained lymph node than in the group with unstained lymph node. The index of the CN group was higher than that of the MB group. Conclusion:The tracing effect and lymphatic tropism of CNs were stronger than MB. The thyroid lymph tracer technique may promote the normalization and thoroughness of lymph node dissection in thyroid cancer.
ABSTRACT
Thyroid cancer spreads predominantly via the lymphatics to the local draining lymph nodes.This is a review about it.We also report about the role of sentinel node biopsy in thyroid cancer.
