Background and purpose:Previous studies have revealed potential roles for Ezrin in a variety of cancers. Ezrin participates in several functions including cell adhesion, motility and cell survival, and there is increasing evidence that it regulates tumour progression. This study aimed to determine the differential expression of Ezrin between cervical cancer tissues and normal controls and to explore the association of Ezrin expression with clinical pathological characteristics and with the expression of PCNA, MMP-2, MMP-9 and HPV E6 protein. Methods:Retrospective study was performed among 30 cervical cancer tissue samples which were diagnosed in our hospital from Jan. 2002 to Dec. 2006. Ten normal cervixes from uterine myomas were employed as normal controls. Semi-quantitative immunohistochemisty analysis was performed to detect the association of Ezrin expression with clinical pathological characteristics, and with expression of PCNA, MMP-2 and MMP-9, HPV E6 protein in cervical cancer tissue and normal controls. Analyze the association of Ezrin expression with the clinical characteristics. Results:The expression of Ezrin was strong and the distribution was diffuse mainly in the cytoplasm and membrane in cervical cancer tissues, while the normal cervical tissues was weak and mainly in the membrane. However, there was no signiifcant association between the expression of Ezrin and the clinical characteristics including tumor stage, histology and grade. Ezrin expression was positively correlated with the expression of MMP-2, MMP-9 and HPV E6 protein in cervical cancer tissues, except PCNA. Conclusion:Ezrin was over-expressed in cervical cancer tissues and may be involved in the progress of invasion and metastasis in cervical cancer.

Inflammatory bowel disease (IBD) is a group of intestinal chronic non-specific inflammatory disease with unknown etiology, and includes ulcerative colitis (UC) and Crohn''s disease (CD).Studies have indicated that environmental factor, genetic factor, disorder of immunity are associated with the pathogenesis of IBD.More and more basic and clinical studies focus on treatment with helminths in IBD.The accumulated evidences have shown that helminths infection has beneficial effects on the alleviation of IBD and is relatively safe.This article reviewed the advances in study on helminths in the treatment of IBD.

Objective To explore the method of the major hospital indexes examination using clinical pathway as an opportunity.Methods Based on the material of our hospital from 2008 to 2010,reference the data of the same level hospital in Xinjiang Uygur Autonomous Region,we set the benchmark and formulated the examination standard of three examination indexes:average length of stay (ALOS),average hospitalization expense and drug proportion.Meanwhile,we took the subentry incentives to give the corresponding reward to clinical departments according to the decreases rate compared with the benchmark monthly.Results ALOS,average hospitalization expense and drug proportion of department and the whole hospital were obviously decreased compared with the same period last year,and the differences were statistically significant (Medical system:t =27.479,14.462,11.362,all P ＜ 0.01 ; Surgical system:t =18.944,16.029,12.071,all P ＜ 0.01).Conclusion After using the examination methods and combining clinical pathway,the effects are obvious,which can effectively shorten ALOS,reduce average hospitalization expense and drug proportion,so as to relieve the patients' economic burden.

Purpose This paper was to investigate the correlation between in vitro and in situ methods for propafenone transnasal absorption.MethodsUsing excised sheep nasal mucosa permeation test in vitro and rat nasal infusion test in situ. By means of changing the medium pH, drug conoentration, and forming β-cyclodextrin inclusion compound, the permeability coeffident (Pm), mean permeation rate, and permeation fraction were determined in vitro. Under the corresponding conditions the absorption rate oostant(k ) ,mean absorption rate and absorption fraction in situ were also detrmined.ResultsThe linear regression coefficient indicated that,under the various experimental conditions,a good in vitro-in situ correlation could be confirmed.ConclusionsHaving an in vitro-in situ correlation is useful for scientific justifying the different methods for nasal absorption studies.

A large number of documents will be generated in the process of new drug research,including lots of references.These data accumulate into institutional repository.Up to now,the management of document knowledge base in the process of new drug research has not yet been published.The paper uses the reference management software,combined with the document knowledge management system,to analyze and research the management model and method for establishing institutional repository.

AIM:To investigate the effects of perfluorocarbon and ligustrazine on lung injury during liver transplantation in pigs with hepatopulmonary syndrome. METHODS:A hepatopulmonary syndrome (HPS) model of pig was established by chronic bile duct ligation. The animals were assigned randomly to 2 groups:(1) Perfluorocarbon in combination with ligustrazine treatment groups (PFCL group):the pigs were treated with intratracheal instillation of perfluorocarbon and ligustrazine; (2) The conventional mechanical ventilation group (MV group):all animals were subjected to mechanical ventilation and orthotopic liver transplantation. After 5 h the lungs were harvested for further analysis. RESULTS:The lung wet to dry weight radio,pulmonary permeation index and leukocyte count in bronchoalveolar lavage fluids (BALF) in PFCL group significantly decreased compared to MV group (P<0.05). Contents of tumor necrosis factor-α (TNF-α) and interferon-γ (IFN-γ) in the lung tissue,plasma and BALF of pigs in PFCL group were significantly lower than those in MV group (P<0.05). Moreover,the activation of NF-κB was inhibited markedly by PFCL. CONCLUSION:Perfluorocarbon in combination with ligustrazine effectively reduces the PMN accumulation in the lungs,inhibits TNF-α and IFN-γ production and protects against lung injury during liver transplantation in pigs with hepatopulmonary syndrome.
