Objective To evaluate the expression of RAR-? gene in cervical carcinoma cell lines SiHa,HeLa,C33A and Caski and to analyze the relation between their gene expression and the promoter methylation of RAR-? DNA.Methods The expression of mRNA and protein of RAR-? gene in the four cell lines were analyzed by RT-PCR,western blot and immunofluoreseence,respectively.Methylation specific PCR(MSP)was used to check whether there was methylation in the promoter of RAR-? gene.The demethylating agent 5-aza-2'-deoxycytidine(5-Aza-cdR)was used to treat methylated cell lines and the change of RAR-? gene methylation and RAR-? gene expression defects were observed.The cell proliferation was assayed with 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide method.Results The mRNA and protein expression levels of RAR-? in cell lines SiHa,HeLa,Caski and C33A were 0.25 ?0.08,0,0.60?0.19,3.12?0.92 and 0.23?0.07,0,0.14?0.05,0.68?0.21,respectively.The mRNA and protein expression of RAR-? in SiHa,HeLa and Caski cell lines were decreased or silenced, whereas its expression increased in C33A cell line.MSP method showed that there were RAR-? gene methylation in SiHa,HeLa and Caski cell lines,while there was no RAR-? gene methylation in C33A cell line.After treated with 5-Aza-cdR,the mRNA and protein expression levels of RAR-? in SiHa,HeLa, Caski and C33A cell lines were 1.82?0.59,2.13?0.62,1.67?0.43,2.95?0.89 and 0.69?0.21, 0.83?0.29,0.56?0.16,0.64?0.20 respectively.The mRNA and protein levels of RAR-? had a significant difference between before and after interference with 5-Aza-cdR in SiHa,Helm,and Caski cell lines(P0.05).The 5-Aza-cdR treatment could suppress cell proliferation.Conclusions The RAR-? gene expression defects play an important role in the carcinogenesis of cervical cancer.Aberrant methylation in promotor region of RAR-? gene may be an important mechanism for the loss of expression of RAR-? gene.

Objective To determine the prognostic significance of positive peritoneal cytology (PPC) among patients with endometrial cancer and to find out potential risk factors for PPC in endometrial cancer.Methods Data were extracted from Peking Union Medical College Hospital between Jan 1 2005 and Dec 31 2010.Only those patients who had undergone a staging procedure were included.A total of 486 patients were identified.Statistical analyses were performed using Fisher`s exact test, Kaplan-Meier log rank, and Cox proportional hazards models.ResultsRate of PPC was 4.8% in endometrial cancer.Non-endometrioid endometrial cancer(P=0.000), stage Ⅲ/Ⅳ(P=0.000), deep myometrial invasion(P=0.001), and cervical stromal involvement(P=0.018) appeared to be risk factors for PPC in endometrial cancer.Univariate analysis revealed statistically difference in 5-year PFS (70.9% vs 90.0%) and 5-year OS (72.2% vs 96.0%).Progression-free survival and overall survival showedstatistically difference(P=0.005,P=0.000)between PPC and NPC endometrial cancer.On multivariate analysis, PPC remained no statistically difference in progression-free survival or overall survival(RR=3.812,95% CI 0.897-16.200,P=0.070;RR=3.426,95% CI 0.800-14.673,P=0.097).Conclusions PPC is not an independent risk factor in patients with endometrial cancer.Aggressive histology, FIGO stage, deep myometrial invasion and cervical stromal involvement are presumed to be associated with PPC in endometrial cancer.

Objective To investigate the high-risk factors of retroperitoneal lymph nodes metastasis (LNM) and the effect of lymph nodes metastasis on prognosis in patients with endometrial carcinoma (EC).Methods Retrospec-tive research was carried out from January 2005 to December 2010 to identify 289 endometrial carcinoma patients treated with retroperitoneal lymphadenectomy at Peking Union Medical College Hospital.The high-risk factors of retroperitoneal LNM and prognostic factors of this disease were studied.Results 1) The median age at diagnosis was 55 years old.Patients of stage Ⅰ, Ⅱ, Ⅲ and Ⅳ were 224 (77.5%), 13 (4.5%), 45 (15.6%) and 7 (2.4%), respectively.Two hundred and eighty-nine patients received pelvic lymphadenectomy, of that 30 (10.4%) patients were found the pelvic LNM.Ninety-six patients received periaortic lymphadenectomy, of that 11 (11.5%) patients were found the periaortic LNM.Twenty-one (7.3%) patients developed recurrent disease and 11 (3.8 %) dead.The median follow-up was 37 months and the median disease-free survival (DFS) was 34 months.2) In univariate analysis, the incidence of LNM significantly increased in patients with CA125 ≥ 35 U/mL preoperatively, non-endometrioid adenocarcinoma, low grade, deep myometrium invasion, diameter of tumor ≥ 2 cm, cervical stroma involvement, positive peritoneal cytology and vagina or parametrial involvement (P<0.05).In multivariate analysis, CA125 ≥ 35 U/mL preoperatively, low grade, deep myometrium invasion were the independent high-risk factors of LNM (P<0.05).3)The Kaplan-Meier analysis showed a significant difference between positive peritoneal cytology, vagina or parametrial involvement, appendix involvement, LNM and DFS (P<0.05).We also found a significant difference in the impact of non-endometrioid adenocarcinoma, low grade, deep myometrium invasion, positive peritoneal cytology, appendix involvement and LNM on overall survival (OS) (P<0.05).Cox regression analysis revealed retroperitoneal LNM is the independent prognostic factor of 5-year DFS (patients without LNM 92.1% vs patients with LNM 65.3%, P=0.002, 95% CI 0.078-0.552).We also found the trend that the 5-year OS was higher in patients without LNM than them with LNM, even though there was no significant difference(patients without LNM 96.1% vs patients with LNM 70.0%, P=0.086, 95% CI 0.039-1.238).Conclusions 1) there is a predictive value of low grade and deep myometrium invasion for EC patients with LNM.2)Patients with LNM have poorer prognosis than them without LNM.Therefore, patients with LNM should receive adjuvant therapy to reduce the risk of recurrence.

Objective To measure the proximal femoral parameters which can provide anatomic evidence for the design of internal fixation components for intertrochanteric fractures of femur.Methods Femoral speci- mens were harvested randomly from 120 healthy adult cadavers(left 60,fight 60).The neck shaft angle,greater trochanter slope length,tilt angle of greater trochanter,axial length of head and neck,lengths of upper and lower borders of the neck,and the minimum transverse diameter of the neck were measured.On the basis of the anatomic study,a two-claw plate was designed to treat 145 cases of femoral intertrochanteric fractures.Results The femoral neck shaft angle was 128.59??6.31?,femoral greater trochanter slope length was(5.5?0.58)cm,tilt angle of femoral greater trochanter was 42.76??5.20?,and axial length of head and neck was(9.42?0.38)cm. There was a correlation between the parameters.All the patients were followed up for a mean time of 23.6 months. The fractures got clinic union in 3 to 6 months.Two cases experienced detachment of claws and hooks but their final outcome was not affected.Three cases suffered coxa vara.All the other cases obtained normal motion function of hips and normal neck shaft angle.No breakage of claw,hook or nail was found in them.Conclusions It is necessary to design an internal fixator that can fit the anatomical features of Chinese femurs in the treatment of intertrochanteric fractures of femur.The two-claw plate designed by us is a good attempt to improve the clinical effect.
