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.

Background and purpose:Gestational trophoblastic neoplasm (GTN) is a spectrum of disease arising from trophoblastic cells, and the majority of patients with GTN have favorable outcome because of the sensi-tivity to chemotherapy. While the cure rate for high-risk patients is still 70% to 80% as a result of drug resistance and disease recurrence. This study aimed to evaluate the clinical characteristics and outcome of patients with high-risk GTN.Methods:The clinical records of patients with high-risk GTN treated in Obstetrics and Gynecology Hospital of Fudan University from Jan. 2003 to Jan. 2013 were analyzed and reviewed retrospectively from the aspect of different treatment.Results:Fifty-one patients with high-risk GTN were admitted to this hospital. Among 51 high-risk GTN patients, 46 patients were evaluated retrospectively and 5 patients were excluded for incomplete treatments. Of the 46 patients with high-risk GTN, 27 patients were treated by chemotherapy alone, 19 patients received chemotherapy and adjuvant surgical therapy. Forty-four patients received EMA-CO (VP-16+Act-D+MTX/VCR+CTX) as a ifrst-line chemotherapy, 81.82% (36/44) had complete remission and 8 patients developed resistance to EMA-CO. EMA-EP (VP-16+Act-D+MTX/VP-16+cisplatin) was used as second-line chemotherapy for the 8 patients resistant to EMA-CO, 6 patients (2 underwent adjuvant surgical therapy) achieved remission and 2 patients died as a result of drug-resistance and disease progression. For the remaining 2 patients, one was treated by 5-FU+KSM and pulmonary resection, and the other was treated by MTX for misdiagnosis as ectopic pregnancy and then converted to EMA-CO for the pathological diagnosis of choriocarcinoma after surgery. Both of them achieved complete remission. Ultimately, 95.65% (44/46)patients achieved complete remission. Among the 19 patients who underwent adjuvant surgical therapy, 94.70% (18/19) patients achieved complete remission after chemotherapy and adjuvant surgery, and the remaining one patient died of disease progression.Conclusion:Standard combination chemotherapy is crucial in the treatment of high-risk GTN. The role of adjuvant surgery in the management of high-risk GTN should not be underestimated.

Objective China is experiencing increasing disease burden and economic burden of acute myocardial infarction(AMI),while the healthcare resources are limited and unevenly distributed.Hospitalization duration is an important measure of health resource utilization index.This study aims to describe the time trend of Length of stay(LOS) for AMI inpatient care in eastern urban areas of China,and to identify potential hospital-level factors associated with the LOS,which is an important indicator of resource utilization.Methods The study randomly selected a representative sample of patients admitted for AMI in 2001,2006 and 2011,from urban hospitals in eastern China.After central data abstraction from medical records,patients' characteristics,treatments and outcomes were compared between 3 hospital groups that were divided according to their median of LOS.Results Five thousand and forty-seven AMI cases were included in the analyses.The average LOS were (15.3±10.2),(13.5±8.7) and (12.2±7.8) d in 2001,2006 and 2011 respectively,with a decreasing trend(F=10.93,P<0.001).After adjusted for patients' characteristics,there were no significant different in LOS between years.Patients' characteristics were similar between high-,middle-and low-LOS hospitals,however,in high-LOS hospitals,use rates of aspirin,clopidogrel and statins were even lower(P≤0.001).LOS were longer 1.9 d in the hospitals with relatively small AMI inpatient treatment volumes(30-80 annually,t=2.97,P<0.01).Conclusions The average LOS for AMI in eastern urban areas of China is much longer than in western countries.Conclusion between hospitals have highlighted the gaps in care quality and efficiency.Standardized clinical pathways and hierarchical medical system are essential strategies in the new healthcare reform.
