Objective: To study the effect on cytotoxicity and drug resistance by blocking ERCCl gene expression in o-varian cancer cell lines. Methods: ERGC1 antisense expression vector was constructed and transfected into human ovarian cancer cell lines. Northern blotting and Western blotting were used to detect the RNA and protein expression level in the cells. Luciferase assay system was used to reveal the host cell reactivation function. MTT assay was used to study the effect on cytotoxicity and drug resistance in the cell lines. Results: After transfection of the antisense ERCCl, Northern and Western blotting indicated that the RNA and protein expression level of ERCCl was obviously decreased. Luciferease assay showed reduced DNA-damage repair capacity as assessed by host cell reactivation. MTT assay also showed decreased drug resistance to cisplatin in the lines. Conclusion: Transfection of antisense ERCCl may enhance the cisplatin cytotoxicity by disturbing the NER pathway in cisplatin-resistant cell lines.

[Objective]To investigate the relationship of baseline antimullerian hormone(AMH)and live birth rate of IVF/ICSI and further explore the prognostic effect of AMH on live birth rate.[Methods]All non-polycystic ovary patients who underwent their first embryo transfers in our unit and had basal serum AMH evaluated between 2010 and 2015 were evaluated in this retrospective study. Patients were grouped according to their AMH level,i.e. low AMH group with AMH less than 1.1 ng/mL(n = 485),middle AMH group with AMH between 1.1 ng/mL and 7.0 ng/mL (n = 1 989),and high AMH group with AMH higher than 7.0 ng/mL (n=468). For age subgroup analysis,patients were stratified as follow:group A(age≤29 years),group B(30~34 years),group C(35~39 years)and group D(over 40 years). We compared clinical outcomes between AMH groups in different age groups usingunivariate and multivariate analysis. ROC analysis was utilized to assess predictive value of AMH on live birth rate.[Results](1)In both fresh and frozen embryo transfers,baseline AMH was significantly related to clinical outcomes. The lower AMH was,the lower implantation rate,clinical pregnancy rate,and live birth rate. However,higher miscarriage rate was observed. All difference reached statistically significant.(2)In age subgroup analysis,we demonstrated AMH was related to live birth rate in patients in group A,B, and C,regardless of fresh or frozen embryo transferred. In those over 40 years,AMH was related to live birth rate in frozen cycles (P < 0.05)but not fresh cycles(P = 0.092). The further multivariate analysis confirmed the above results after controlling po?tential confounding variables.(3)The AUC of ROC analysis for AMH predicting live birth rate were 0.647,0.633 for fresh and fro?zen cycles respectively.[Conclusion]Baseline AMH as one of excellent ovarian reserve markers ,was significantly related to live birth rate in fresh or frozen cycles. Baseline AMH was an independent prognostic factor of live birth rate,but its predictive value on live birth rate was of limited clinical value.

Purpose To retrospectively analyze and summarize the image features of rare ovarian clear cell carcinoma (OCCC), and to provide basis for clinical diagnosis. Materials and Methods CT and MRI features of 30 cases of OCCC confirmed by pathology were retrospectively analyzed. Sixteen of all the patients underwent pre- and post-contrast CT scan. And 14 patients underwent pre- and post-contrast MRI scans. Results ① CT features: unilateral mass was revealed in 15 cases and bilateral mass was in 1 case. The maximum diameter of the mass ranged from 8 to 23.7 cm, mean (12.86±3.96) cm. One mass was irregular, 4 masses revealed incomplete capsule, and 4 masses had septa in the mass. CT value of cystic part of the mass was 20-30 HU, and which of solid part was 28-53 HU. On post-contrast CT images, the septa and solid component of the mass showed marked enhancement and delay enhancement, while the cystic component showed no enhancement. ② MRI features: Unilateral mass was revealed in 13 cases and bilateral mass was in 1 case. The maximum diameter of the mass ranged from 9.2 to 30.0 cm, mean (14.03±4.72) cm. One mass was irregular, 2 masses revealed incomplete capsule, and 2 masses had septa in the mass. The cystic component showed heterogenous signal intensity on T1WI, and high signal intensity on T2WI. There was no enhancement on post-contrast images. The solid component showed iso-intensity on T1WI, high signal intensity on T2WI, and diffused restricted on diffusion-weighted images. There was markedly enhancement on post-contrast images. ③ Blood supply of the tumor: In 8 cases, the branch of enlarged ipsilateral ovarian artery fed the tumors. In other 16 cases, the masses were surrounded by enlarged ipsilateral ovarian vein. Conclusion The characteristic CT and MRI features of OCCC include: a cystic solid mass with complete capsule; the solid component projects into the cavity, which could be hypervascular and marked enhanced.

according to the difference of femoral eccentricity on the affected and healthy sides. In the reduction group (30 cases), the difference value was <-5 mm. In the normal group (87 cases), the difference value was -5-5 mm. In the increased group (45 cases), the difference value was > 5 mm. Femoral stem and femoral prosthesis type were compared among different groups. SF-12 scale score, Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) and Harris score were evaluated and compared before and after replacement. RESULTS AND CONCLUSION:Standard eccentricity of femoral prosthesis mainly accounted for 77%, 63% and 73% in the reduction group, normal group and increased group, respectively (P > 0.05). No significant difference in average eccentricity was detected in each group between the affected and healthy sides (P> 0.05). WOMAC score was significantly higher after replacement than that before replacement in three groups (P < 0.05). No significant difference in WOMAC score was found among three groups before replacement (P > 0.05). No significant differences in pain and stiffness were detected among three groups after replacement (P > 0.05), and significant differences in physical function were found (P < 0.05). The physical function was highest in the normal group. No significant difference in SF-12 scale score was seen in the three groups before and after replacement (P > 0.05). The physical ability score was elevated after replacement in the three groups (P < 0.05). Mental scores were significantly elevated in reduction and normal groups (P < 0.05). The excelent and good rate of Harris score was significantly higher in the increased group (96%) than in the reduction group (70%) and normal group (87%) (P < 0.05). These findings indicate that the increased eccentricity contributed to the pain easement after total hip arthroplasty and promoted functional recovery. The decreased eccentricity could worsen patient’s pain, and was not conducive to the restoration of joint function after replacement.
