ObjectiveTo investigate the expression of Twist and N-cadherin in pancreatic cancer,and to study its relationship with clinicopathological parameters and patients' prognosis.Methods The expression of the Twist and N-cadherin in 62 tissue samples from patients with pancreatic ductal adencocarcinoma and 10 normal pancreatic tissue samples was determined by using immunohistochemistry MaxVision two step method,and the relationship with clinicopathological parameters and patients' prognosis was analyzed.ResultsThe positive expression rate of Twist in pancreatic cancer was higher than that of normal pancreatic tissues (96.8％ vs.30％,P ＜0.01 ),and the positive expression rate of N-cadherin was higher than that of normal pancreatic tissues (75.8％ vs.0,P ＜0.01),but there was no correlation between them (r =0.100,P =0.441 ).The expressions of Twist and N-cadherin was significantly correlated with TNM stage,lymph node metastasis,infiltration of portal vein or nerves and tumor location ( P ＜0.05 ),but not with age,gender and degree of differentiation ( P ＞ 0.05 ).The post-operative survival of patients decreased with the increasing Twist expression,but the survival was not associated with the expression of N-cadherin.TNM stage,the expression of Twist was independent predictive factors of prognosis for pancreatic cancer patients.ConclusionsTwist and N-cadherin are highly expressed in pancreatic cancer,and the expression was associated malignant behavior of pancreatic cancer.The abnormal expression of Twist may be a potential marker for prognosis evaluation of pancreatic cancer patients.

Objective To explore the diagnostic and score value of ultrasound on hemophiliac arthropathy referring to MRI on the diagnosis and score of hemophiliac arthropathy Methods The ultrasound and MRI examinations were performed on 42 joints of 42 hemophilia patients 14 knees 14 ankles and 14 elbows The consistency of ultrasound and magnetic resonance imaging in the detection and score of joint diseases was compared Finally inter-and intra-observer agreement of ultrasound scoring system were tested Results The consistency of ultrasound and magnetic resonance imaging was excellent κ=0 763-0 896 P < 0 001 in the detection of early soft tissue lesions effusion or hemarthrosis synovial hypertrophy hemosiderin excellent κ=0 793 P <0 001 in the detection of cartilage loss poor κ=0 133 P = 0 132 in the detection of erosions and poor κ= 0 100 P = 0 137 in the detection of subchondral cysts The consistency of ultrasound and magnetic resonance imaging was good to excellentκ=0 684-0 833 P < 0 001 in the score of early soft tissue lesions effusion or hemarthrosis synovial hypertrophy and hemosiderin and poor to good κ=0 145 -0 635 P <0 001 in the score of advanced osteochondral lesions cartilage loss and bone erosions The inter-observer agreement was good to excellent κ=0 676-0 870 P <0 001 for early soft tissue lesions and moderate to excellent κ=0 421- 0 75 1 P < 0 001 for advanced osteochondral lesions The intra-observer agreement was good to excellent κ=0 705-0 885 P <0 001 for early soft tissue lesions and moderate to good κ=0 532 -0 732 P <0 001 for advanced osteochondral lesions Conclusions Ultrasound plays an important role in detecting early soft tissue changes effusion or hemarthrosis synovial hypertrophy hemosiderin and cartilage loss which helps follow-up and guide clinical treatment.

Objective To explore the effect of JianpiYiqi Decoction on the proliferation,invasion and apoptosis of Human hepatoma Huh-7 cells under the constructed inflammatory microenvironment stimulated by lipopolysaccharide(LPS)and adenosine triphosphate(ATP),and to detect the interleukin-1β(IL-1β)and interleukin-18(IL-18)Expression level in cells.Methods Construction drug-containing serum of JianpiYiqi.Adopt LPS and ATP were added to the cell culture medium to stimulate hepatoma cells and construct the inflammatory microenvironment.The cells were divided into blank group,model group,VX-765 group(10 μmol·L-1),low concentration of traditional Chinese medicine group(15%JianpiYiqi Decoction low dosedrug-containing serum),Medium concentration of traditional Chinese medicine group(15%JianpiYiqi Decoction Medium dose drug-containing serum),and high concentration of traditional Chinese medicine group(15%JianpiYiqi Decoction high dose drug-containing serum).Adopt CCK-8 method was used to detect the proliferation level of cells in each group after cell intervention;The apoptosis rate of cells in each group was detected by Annexin V-FITC/PI method;Adopt Transwell method was used to detect the level of cell invasion in each group;adopt PI single staining was used to detect the cell cycle level in each group;Adopt ELISA method and Western blot method were used to detection of IL-1β and 1l-18 expression level in Huh-7 cells.Results Compared with the blank group,in the model group stimulated by LPS and ATP,the proliferation level,invasion level,IL-1β and IL-18 expression level of Huh-7 cells were higher(P<0.05),and the apoptosis level was lower(P<0.05).Compared with other groups,the Medium concentration of traditional Chinese medicine group and the high concentration of traditional Chinese medicine group could effectively inhibit the proliferation and invasion level of Huh-7 cells,block the cell proliferation cycle,reduce the cell survival rate(P<0.05),significantly induce apoptosis of Huh-7 cells(P<0.05),and reduce the expression levels of IL-1β and IL-18 in Huh-7 cells(P<0.05).Conclusion The drug-containing serum JianpiYiqi.The medium and high concentrations of JianpiYiqi Decoction drug-containing serum can inhibit the proliferation and invasion,block the cell cycle and induce apoptosis of human liver cancer Huh-7 cells by improving the inflammatory microenvironment in liver cancer Huh-7 cells.Its mechanism may be related to the inhibition of liver cancer cells.Analyze the levels of inflammatory factors IL-1β and IL-18 to achieve the therapeutic purpose of primary liver cancer.
