Objective To investigate the safety and effectiveness of laparoscopic surgery for early ovarian cancer. Methods Selected 90 early-stage ovarian cancer patients from January 2010 to December 2014 in Zhejiang Cancer Hospital as research subjects, and randomly divided into laparoscopic surgery group and laparotomy group. Then compared the age, BMI, ovarian cancer diameter, ovarian cancer staging, blood loss, operative time, surrounding or﹣gan damage, albumin difference before and after surgery, postoperative ventilation time, postoperative hospital stay, interval of postoperative to the first chemotherapy, postoperative fever cases, follow-up time, postoperative complica﹣tions, postoperative recurrence and postoperative death in two groups. Results Blood loss and operative time of la﹣paroscopic surgery group was less than that of laparotomy group (P< 0.05). Albumin difference before and after surgery of laparoscopic surgery group was less than that of laparotomy group (P< 0.05), postoperative ventilation time and interval of postoperative to the first chemotherapy of laparoscopic surgery group was less than that of la﹣parotomy group (P< 0.05), the incidence of postoperative fever and postoperative complications of laparoscopic surgery group was less than that of laparotomy group (P< 0.05), the recurrence rate and postoperative mortality rate of laparoscopic surgery group were slightly higher than that of laparotomy group, but the difference was not statisti﹣cally significant (PP> 0.05). Conclusion Laparoscopic surgery for early-stage ovarian cancer has a relatively good safety and efficacy. Laparoscopic surgery has advantages over open surgery in improving early ovarian cancer intra﹣operative situation and postoperative situation.

Ovarian cancer is one of the highest mortality rate of gynecologic malignant tumors. Chemotherapy can improve the survival rate of the traditional ovary. In recent years, PARP [poly(ADP-ribose)polymerase]inhibitors in breast cancer susceptibility gene (breast cancer susceptibility gene, BRCA) mutations in patients with ovarian cancer can significantly improve the disease-free survival, may change the prognosis of patients with ovarian cancer. This part of PARP [poly(ADP-ribose)polymerase] inhibitors, inhibiting the repairment of DNA damage in tumor cell, causing DNA damage accumulation, eventually killing tumor cells.In breast cancer susceptibility gene 1 (breast cancer susceptibility gene1, BRCA1)/BRCA2 mutation patients with ovarian cancer, PARP inhibitors and BRCA mutation of the synthetic lethal effect provides a new direction for the development of anti-cancer drugs. Now, many highly selective and sensitive PARP inhibitors have been developed and applied in clinical trials.Although PARP inhibitor monotherapy can produce a therapeutic effect in BRCA mutation in patients with ovarian cancer, but the clinical application is still used in combination with other chemotherapy or radiotherapy. This review is focused on the recent progress in clinical trials of PARP inhibitors in combination with common chemotherapeutic agents.

Objective: To explore the eff ect of Fasudil on the invasion and metastatic abilities of human high metastatic liver cancer cells (HCCLM3) and the underlying mechanisms. Methods: HCCLM3 cells were incubated with 100 μmol/L Fasudil. Fluorescence staining forF-actin and Transwell assay were performed to observe the invasion ability of HCCLM3 cells. HCCLM3 cells were divided into 3 groups: a negative control group, a Fasudil group and a BTB/POZ domain containing 7 (BTBD7)-siRNA group. Western blot assay was performed to detect the expression levels of BTBD7, ras homolog family member C (RhoC) and Rho-associated, coiled-coil containing protein kinase 2 (ROCK2), matrix metalloproteinases 2 (MMP2) and MMP9. Zymogram analysis method was performed to detect the expression activities of MMP2 and MMP9. hTe BTBD7-siRNA group was served as a positive control. Results: In HCCLM3 cells treated with Fasudil, the invasion ability was significant decreased compared with the control group, concomitant with the down-regulated expression levels of BTBD7, RhoC and ROCK2 protein as well as the decreased activities of MMP2 and MMP9. Conclusion: Fasudil plays an important role in interfering BTBD7-ROCK2 signaling pathway and suppressing the invasion and metastasis of hepatocellular carcinoma.

Objective The aim of this study was to evaluate the clinical factors contributing to the operative effects in patients with acetabular fracture.Methods A total of 129 cases of patients with acetabular fracture were retrospectively analyzed from Jun 2006 to Jan 2011 in The Second Hospital of Shaoxing.Of the 129 acetabular fracture patients,96 cases were in the superior group and 33 patients in the inferior group according to Merled'Aubigne-Postel methods.The potential clinical factors related to the operative effects in acetabular fracture patients were evaluated by the method of logistic regression analysis.Results The superior rate was 74％ in this study.Single factor analysis demonstrated that the diaplastic quality(x2=21.53,P ＜0.01),the femoral cartilage defect(x2 =17.50,P ＜0.01),the inra-aticular free bone(x2=12.18,P =0.0005),the type of fracture (x2 =7.24,P =0.0071) and the timing of operation (x2 =4.36,P =0.037) were correlated with operative effects in acetabular fracture patients.The binary logistic regression analysis indicated that non-anatomic diaplastic (OR =4.17,P =0.01)and the femoral cartilage defect(OR =3.11,P =0.03) were independent risk factors for operative effects in patients with acetabular fracture.Conclusions The prognosis of patients with acetabular fracture,which was complex,was affected by multiple factors.And introperatively,the anatomic reestablishment should be performed in order not to affect the post operative hip function.

Objective To investigate the expression of Semaphorin 3F (SEMA3F) protein in hepatocellular carcinoma (HCC) and to demonstrate its relationship with clinicopathological features and prognosis of HCC. Methods Western Blotting was carried out in 32 hepatocellular carcinoma samples and matched perineoplastic tissues to detect the expression of SEMA3F protein. The relationship between SEMA3F protein expression and clinicopathological features as well as prognosis of HCC patients was analyzed. Immunohistochemistry was used to show the location of SEMA3F in HCC cells and its relationship with microvessel density (MVD). Results The expression of SEMA3F protein in HCC tissues was significantly higher than in the perineoplastic tissues (447.78± 48.26 vs 618.93 ±61.23, P＜0. 05) and it was correlated closely with tumor capsulation and tumor nodular number (P＜0.05). Based on the Western Blotting and clinical follow-up data, we found that the survival time of HCC patients with a higher SEMA3F expression level was longer than those with a lower level, and the recurrent/metastatic time of HCC patients was significantly different between these two groups (P＜0.01). Immunohistochemistry demonstrated that SEMA3F protein localized in the cytoplasm of HCC cells and its expression correlated with HCC MVD. MVD in the low-level group was higher than the high-level group (115.6±30.38 vs 86. 56±17.94, P＜0.01). Conclusions SEMA3F expression in HCC was significantly down-regulated and correlated closely with tumor-capsulation, nodular number, and MVD, implicating SEMA3F may play an important role in recurrence and metastasis of HCC. It can be regarded as a prognostic marker in HCC patients.

Objective To study the effect of age on the recurrence-free survival rate after hepatic resection for hepatocellular carcinoma(HCC)and the relationship between microvessel density (MVD)and recurrence of HCC in the elderly. Methods　Severty one cases of elderly patients with HCC were analyzed retrospectively with 352 cases of non-elderly HCC patients as control,and the effect of age on the recurrence-free survival rate was studied.The expressions of CD34 and endocan in HCC tissues were detected by immunohistochemistry in 30 elderly and 30 non-elderly patients.Results　The 1-,3- and 5-year recurrence free survival rates were 75.7%,43.0% and 43.0% in the elderly group respectively,which were higher than those in the non-elderly group(53.6%,38.5% and 33.4%,respectively,Log Rank value=10.25,P＜0.05).The positive rate of alpha fetoprotein (AFP)in the elderly group was 47.9%,which was lower than that in the non-elderly group(62.2%)(X2=23.68,P＜0.05).The median survival times in the high CD34-MVD group and high endocan MVD group were shorter than those in the low CD34-MVD group and low endocan-MVD group(260 d vs.850 d,360 d vs.800 d,Log Rank value was 22.18 and 20.56 respectively,both P＜0.05).Conclusions　The long-term prognosis of hepatic resection for HCC is better in elderly patients than in non-elderly patients.The recurrence of HCC in the elderly is closely related with angiogenesis.

Objective: To observe the effect of extracorporeal shock wave therapy (ESWT) on proliferation, cell cycle and intercellular adhesion molecule-1 (ICAM-1) expression in human umbilical vein endothelial cells (HUVECs). Methods: HUVECs were culturedin vitro at the concentration of (1×105/ml) and the cells were divided into 2 sets of groups:CSWT group, the cells were treated by different energy of (0.03, 0.09, 0.18, 0.24) mJ/mm2 respectively and corresponding Control group, in which the cells had no CSWT. HUVEC proliferation was detected by CCK colorimetric method, cell cycle was measured by lfow cytometry, mRNA and protein expressions of ICAM-1 were examined by RT-PCR and Western blot analysis respectively. Results: Compared with Control group, (0.09 mJ/mm2) CSWT group had promoted HUVECs proliferation,P<0.05 and the other CSWT groups were similar to corresponding Control groups,P>0.05; (0.09 mJ/mm2) CSWT group showed decreased proportion of G0/G1 stage and increased S and G2/M stages, allP<0.05; while (0.03 mJ/mm2) CSWT group only increased the proportion of G2/M stage,P<0.05 and the other CSWT groups were similar to corresponding Control group,P>0.05. Compared with Control group, (0.09 mJ/mm2 ) and (0.03mJ/mm2) CSWT groups showed increased mRNA expression of ICAM-1 (9.27±0.95) vs (1.02±0.27),P<0.001 and (7.08±0.60) vs (1.02±0.27),P<0.01; (0.09 mJ /mm2) CSWT group had elevated protein expression of ICAM-1,P<0.05. Conclusion: ESWT especially at (0.09 mJ/mm2) may accelerate cell cycle transition from G0/G1 stage to S and G2/M stages, promote HUVECs proliferation and increase ICAM-1 expression which may play important roles in ESWT facilitated angiogenesis in vitro.
