Objective To investigate the changes of coagulation and fibrinolysis systems in patients with solid cancer. Determine the mechanism of thrombosis formation in solid cancer and the the metastasis mechanism of solid cancer.Methods To measure plasma concentrations of TF,TFPI,t-PA,u-PA,PAI-1 by ELISA and test protein C activity(PC:A)by chromogenic substrate assay.Results Plasma concentrations of TF,TFPI,u-PA,PAI-1 were all higher in solid cancer patients than normal control and higher in metasta- sized team than non-metastasized team.In the dead team,u-PA and PAI-1 were higher while TFPI was low- er. t-PA was higher in cancer patients combined with venous thromboembolism while protein C activity was lower.Conclusion Disorders of coagulation and fibrinolysis system are related to the thrombosis formation in solid cancer.Coagulation and fibrinolysis factors take part in the metastasis progress of solid cancer. High concentration of u-PA and PAI-1 or low concentration of TFPI are considered to be related with poor outcome.

Objective:To observe the effects of toadpoison and arsenic on the ultrastructure of dental pulp,Methods :Dental pulp of 36 teeth in 3 dogs was exposed by operation and then direct dressing with toadpoison paste or arsenic paste was performed. 1,2,6 and 24 hours after operation ,the pulps were processed and examinedunder a trasmission electron microscope (JEM-2000EX). Results:In toadpoison treated group ,the deformityof the basernembrane of pulp nerve ,swelling of metochondrion,degeneration of nerve axite were observed 1 h after dressing,and were more obvious in 2, 6 and 24 h. Damage of capillary and pulp cells were alsoobserved.In arsenic treated group ,swelling and break of capillaries ,deformity and degeneration of mitochondrion and endoplasmic reticulum in endoepithelial cells were observed,and were more obvious following time lasting. Damages of pulp nerve and pulp cells were also observed. Conclusion:Toadpoison and arsenic are toxic to pulp tissues. But the angiotoxicity of arsenic is stronger than that of toadpoison,the neurotoxicity and protoplasmic toxicity of toadpoison are stronger than those of arsenic.

In eukaryotic cells ,NF-κB transcription factor family regulates many processes like cell sur-vival,growth,and apoptosis.It participates in the development of a variety of diseases ,including inflammatory,im-mune disease ,and cancer .As an inflammatory factor , NF-κB mediates the transformation of chronic colitis to cancer during the course of colorectal cancer .Furthermore,it could inhibit cell apoptosis through regulating cell cycles,which promotes the development of colorectal cancer and mediates the multidrug resistance of the tumor cells.Therefore,targeting NF-κB,a large number of preparations involved both Chinese and western medicine has been researched .The further research and the use of them may be an effective method to cure the colorectal cancer in clinical work .

Objective To investigate the effect of high glucose on the expression of transforming growth factor-?1(TGF-?1),?-SMA,E-Cadherin in renal proximal tubular epithelial cells(HKCs)and role of AG490,an antagonist of Janus kinase.Methods Cultured HKCs cells were divided into four groups:low glucose group(LG),high glucose group(HG),high mannitol group(LG+M),and HG+AG490 group(AG).Immunoprecipitation and Western blot analysis were used to measure the expressions of tryosine phosphorylated Janus kinase 2(p-JAK2),STAT1,STAT3,p-STAT1,p-STAT3 and ?-SMA,E-Cadherin.The contents of TGF-?1 and type I collagen in the supernatants of the cultured HKCs were detected by ELISA.TGF-?1 mRNA were measured by RT-PCR.ResultsCompared with low glucose control group,the expressions of JAK2,p-STAT1,p-STAT3 and TGF-?1 mRNA were significantly increased in HG group from 6 to 72 h.Meanwhile,the contents of TGF-?1 and collagen I in the supernatants and the expression of ?-SMA were increased,the expression of E-Cadherin was decreased.The expression of JAK2,p-STAT1,p-STAT3 and TGF-?1 mRNA and the level of TGF-?1,collagen I in the supernatant s in HG+AG490 group were obviously lower than those of the HG group.The expression of ?-SMA and E-Cadherinwas also decreased in HG+AG490 group.Conclusion Activation of JAK/STAT signaling pathway seems to be involved in the high glucos induced overproduction of TGF-?1 and ECM proteins in HKCs.
