Objective To investigate the effect of over-expressed macrophage migration inhibitory factor (MIF) on epithelial-mesenchymal transition (EMT) in human cervical carcinoma SiHa cells.Methods Recombinant eukaryotic expression plasmid liposome enhanced transfection of green fluorescent protein gene (pEGFP-N1)-MIF was constructed and then transfected into human cervical cancer SiHa cells.Experimental cells were classified into three groups (SiHa-pEGFP-N1-MIF,SiHa-pEGFP-N1,and SiHa).Western blot was used to detect the expression of MIF protein,and the expressions of EMT-related markers such as E-cadherin and vimentin in SiHa cells were determined before and after transfection.Results The eukaryotic expression vector pEGFP-N1-MIF significantly increased the expression of MIF protein in SiHa cells (P ＜ 0.05),and after overexpression of MIF gene in SiHa cells,the expression of E-cadherin protein in SiHa-pEGFP-N1-MIF group was significantly lower than that in control groups (P ＜0.05),while the expression of vimentin in SiHa-pEGFP-N1-MIF group was significantly higher than that in control groups (P ＜ 0.05).Conclusions Overexpression of MIF in cervical cancer SiHa cells can promote the EMT occurrence.

Objective To investigate the expression and significance of tumor suppressor gene PTEN and oncogenes Ki- ras in endometrioid endometrial adenocarcinoma(EEC). Methods The expression level of PTEN and p21ras were detected with the S- P immunohistochemistry method in 20 cases of normal endometrium, 20 cases of uterus atypical hyperplasia endometrium and 45 cases of EEC. The relationship between the gene expression and clinicopathological features was analyzed. Results The expression level of PTEN decreased progressively, and was 95.0 %, 40.0 %, 31.1 % respectively in normal, atypical hyperplasia endometrium and EEC. The expression level of PTEN was significantly higher than in normal in atypical hyperplasia and EEC(P

Objective To investigate the effect of neoadjuvant chemotherapy on the prognosis of patients with cervical cancer.Methods A systematic review of the literature about neoadjuvant chemotherapy and radical surgery was performed with searching Pubmed,Cochrane library,Medline,and Embase database from January 1990 to January 2015.According to the inclusion and exclusion criteria,the data were extracted and analyzed by Revman 5.3 system software Meta.Results Ten controlled clinical studies were concluded,including 1 543 patients (667 in preoperative neoadjuvant chemotherapy group and 876 in radical surgery).The extracted data were comparable.Meta-analysis results displayed that significant difference existed in five-year disease-free survival,node-positive rate,vascular invasion rate,and parametrial infiltration rate.It seemed that the preoperative neoadjuvant chemotherapy was prior to the radical surgery in those items.There was no significant difference between the preoperative neoadjuvant chemotherapy and radical surgery in five year survival,intraoperative complication,the positive surgical margin rate,and five-year survival rates among different chemotherapy peers (P ＞ 0.05).Conclusions For locally advanced cervical cancer patients,neoadjuvant chemotherapy can reduce the incidence of high-risk pathology,but had no significant effect on the long-term survival of patients.

Objective To observe the effect of drug edible of herbal medicine granule on vascular endothelial function in patients with coronary heart disease(CHD).Methods A total of 200 cases featuring with cardiovascular blood stasis were chosen from patients who were diagnosed with CHD in Zhengzhou hospital of traditional Chinese medicine from January 2015 to January 2016.All cases were divided into observation group(n=98)and control group(n=102).The observation group was given Xin bao drug edible of herbal medicine granule and conventional drugs,and the control group was given conventional drugs.After 8 weeks of observation,the levels of endothelin(ET-1),nitric oxide(NO)and angiotensin Ⅱ(AngⅡ)were measured by enzyme-linked immunosorbent assay(ELISA).The serum levels of total cholesterol(TC),triglyceride(TG),low density lipoprotein(LDL),and TCM clinical symptom score were compared between the two groups.Results The level of TC of the control group was decreased after treatment(P<0.05);the levels of TC,TG and LDL in the observation group were lower than those in the control group(P<0.05).After treatment,the levels of NO,ET-1,Ang-Ⅱ and FMD in the observation group were significantly different from those before treatment(P<0.05).The levels of NO and FMD in the observation group were higher than those in the control group,and the levels of ET-1 and Ang-Ⅱ were lower than those in the control group(P<0.05).After treatment,the scores of TCM clinical symptoms in the observation group were lower than those before treatment(P<0.05).Compared with the control group,the total score of palpitations,the times of shortness of breath and clinical symptoms were lower than those in the observation group(P<0.05).Conclusion Xin bao drug edible of herbal medicine granule could relieve coronary heart disease blood stasis type of patients with vascular tension,reduce its endothelial cell damage and improve its clinical symptoms.

Objective To determine the correlation between the expression of interleukin 8(IL-8) and lymph node metastases in earlier uterine squamous cervical cancer and to study the mechanism of metastases of earlier squamous cervical cancer. Methods IL-8 mRNA expression was examined with reverse transcription polymerase chain reaction(RT-PCR) and tissue microarray to determine the expression of IL-8 protein. The matrix metalloproteinase 9( MMP-9) protein and microvessel density (MVD) in earlier squamous cervical cancer were decided respectively by antibody against IL-8, MMP-9 and CD-34 associated antigen and Immunohistochemical analysis. Results The cervical cancer with lymph node metastases express IL-8, MMP-9 and MVD at significantly higher level than negtive metastatic lymph node(P =0.00,0.00,0.02). Otherwise, the express of IL-8 correlated strongly and positively with MVD of cervical cancer(r =0.251,P

With the concepts of minimal invasive surgery and precision medicine embedding deeply in modern medicine, traditional clinical treatment strategies are constantly updated due to the rapid progression of medical research. Systematic dissection of the regional lymph nodes is a key component in the surgical therapy of gynecologic malignancies, however it may result in a series of complications, such as lower extremity lymphedema, deep venous thrombosis, immune disorders and so on, which seriously impact the patients' quality of life. The necessity of systematic lymphadenectomy and the extent of lymph nodes resection have always been one of the most controversial issues in gynecologic oncology. In recent years, the extensive application of sentinel lymph node (SLN) technology has been increasingly used in the treatment of gynecologic malignancies, which may provide important guidance on this issue. This article reviews the clinical application status, detection methods, detection efficiency, and current controversies regarding SLN mapping and biopsy in cervical cancer, endometrial cancer, ovarian cancer and vulvar cancer, discussing the application value of SLN technology in gynecologic oncology.

Objective To discuss the impact of the pattern of student-autonomous laboratories opening on the experimental teaching of rehabilitation specialty. Methods Laboratories were opened to sophomore students of rehabilitation specialty. Planned opening pattern is employed on students of 2009 class and autonomous opening pattern is used on students of 2010 class. At the end of each term, results of these opening patterns are compared. Results The total opening hours of planned opening pattern were 89 with 755 person-times involved. The accumulated opening hours of autonomous opening pattern were 323 with 2677 person-times involved. Students of the autonomous opening pattern class achieved better academic results than students of planned opening pattern (P<0.05) in 7 major courses. Opening laboratories to students contributed to the improvement of rehabilitation skills, better understanding of the curricular knowledge, the enhancement of problem-analyzing and problem solving abilities, the stimulation of interest in major study and also the fostering of teamwork spirit. And the autonomous opening pattern achieved more desirable results (P<0.05). Conclusion The student-autonomous lab opening pattern contributes more to the improvement of students' practical skills, innovative spirit as well as comprehensive clinical rehabilitation abilities.
