Hypoxia-inducible factor-alpha-1 (Hif-lalpha) is an active-transcription nucleoprotein produced in cellular hypoxia condition, and HIF-1 can bring tissues into adaptation reaction when the tissues are in state of hypoxis. Apart from that, the factor is involved in angiogenesis of ovarian tumor, energy metabolism, invasive metabasis of the tumor and prognosis. Therefore, a new treatment of ovarian tumor may rely on the thorough study of the relationship between HIF-1 and the tumor by investigating its expression and mechanism.

Objective To examine the expressions of hypoxia inducible factor?1α( HIF?1α) and trans?forming growth factor?β1 ( TGFβ1) in patients with endometrial carcinoma,to investigate their clinical signifi?cances. Methods Fifty?four patients with endometrial carcinoma and 20 patients with normal endometrium were selected in Yijishan Hospital of Wannan Medical College from2012 to 2015. Expression of HIF?1αand TGF?β1 were detected by immunohistochemical method respectively,the correlations between HIF?1α,TGF?β1 and clinic pathologic characteristics and prognostic significance were analyzed. Results The positive expression rates of HIF?1αand TGF?β1 were 59. 26%( 32/54) and 64. 81%( 35/54) in endometrial carcinoma respectively,signifi?cantly higher than of expression of patients with normal endometrium ( 5. 00%( 1/20 ) , 0 ( 0 );χ2 =17. 390, 24. 596;P<0. 01). The expressions of HIF?1α were correlated with FIGO stage(χ2=6. 712,P=0. 010),tumor thrombus in pulse tube(χ2=4. 804,P=0. 036),deep myometrial invasion(χ2=6. 484,P=0. 011),and lymph node metastasis(χ2 = 5. 732, P= 0. 017 ) . The expression of TGF?β1 were correlated with FIGO stage (χ2=4. 878,P=0. 027) ,deep myometrial invasion(χ2=4. 060,P=0. 044) and lymph node metastasis(χ2=5. 211, P=0. 022). Expression of HIF?1αwas positively correlated with expression of TGF?β1(r=0. 705,P=0. 000) . Conclusion Increased expressions of HIF?1αand TGF?β1 are all involved in carcinogenesis,progression and metastasis of endometrial carcinoma,which may be considered as a target in endometrial carcinoma therapy.

Objective To investigate the value of neutrophil-to-lymphocyte ratio in evaluation of prognosis in patients with early cervical cancer before radical resection. Methods A restropective study was performed in 76 patients who underwent radical resection for early cervical cancer in our hospital between 2007 and 2009. All patients were diagnosed by pathology. All patients did not accept neoadjuvant therapy , the median value of neutrophit-to-lymphocyte ratio (NLR) was 1.94 (0.73-9.31 in range). Based on this value of 1.94 as threshold, all patients were divided into 2 groups: a low NLR(≤1.94, n=38) group and a high NLR ( >1.94, n=38) group. Univariate and multivariate analyses were performed to assess the effectiveness of preoperative NLR to the prognosis in patients who underwent radical hysterectomy combined with pelvic lymph node dissection. Results The preoperative NLR was different significantly in the depth of stromal infiltration, lymphatic metastas, FIGO stage and pathological type between the low NLR group and the high NLR group. The high NLR group, lymphatic metastas, postoperative radiotherapy and FIGO stageⅡ were all risk factors for prognosis and disease-free survival in univariate analysis.Multivariate analysis revealed that NLR, lymphatic metastas and FIGO stageⅡwere independent risk factors for disease-free survival. FIGO stageⅡand lymphatic metastasis were independent risk factors for overall survivaI. Conclusion Preoperative NLR was found to correlate to unfavorable histopathologic features of cervical cancer. The preoperative NLR may be used as a useful and easy biomarker for disease-free survival in patients with cervical cancer, but not an independent risk factor for poor prognosis.

AIM:To evaluate the clinical efficacy and safety of pneumoperitoneum-free single-hole endoscopy combined with ropivacaine local infiltra-tion anesthesia in pregnancy with ovarian tumor.METHODS:Twenty-eight pregnant women with ovarian tumor were randomly divided into two groups:observation group(n=16)and control group(n=12).The first time out of bed,ventilation time,postoperative hospital stay,non-invasive blood pressure,heart rate(HR),respiratory fre-quency(RR)and blood oxygen saturation(SpO2)were compared between the two groups.Pain score,Ramsay sedation score,SAS anxiety score,postoperative complications,patient satisfaction and recovery quality scale QoR15 were evaluated at 6,24 and 48 hours after operation.RESULTS:There was no significant difference in postopera-tive hospital stay,Ramsay score,RR,SpO2 and the incidence of complications between the two groups(P>0.05),but the time of getting out of bed and ventilation time were shortened,the scores of non-invasive blood pressure,HR,pain and anxiety in the observation group were lower than those in the control group,and the scores of patient satisfac-tion and QoR15 in the observation group were bet-ter than those in the control group(P<0.05).CON-CLUSION:The application of pneumoperitoneum-free single-hole endoscope combined with ropiva-caine local infiltration anesthesia in pregnancy with ovarian tumor can reach satisfactory clinical re-sults,including reducing postoperative pain and anxiety,which is worth popularizing.
