Objective: To evaluate the efficacy and safety of lobaplatin combined with docetaxel in the treatment of the recurrent ovarian carcinoma. Methods: We collected 31 patients who diagnosed as recurrent ovarian carcinoma according to the histopathology or cytology from Tumor Hospital of Hunan Province from January 2011 to January 2013. The patients received cisplatin-based chemotherapy or carboplatin-based chemotherapy before the combined chemotherapy of docetaxel and lobaplatin. For patients with the recurrence, they received a treatment at a dose of 80 mg/m2 for docetaxel on day 1 and a dose of 30 mg/m2 for lobaplatin on day 2, which lasted for 21 days as a treatment cycle. hTe patients received 6-cycletreatment at most. Results: A total of 153 cycles of chemotherapy were given to 31 patients, with a median of 4 (2–6) cycles. Three patients showed complete response, 11 partial response, 2 stable disease, and 15 progressive disease. hTe objective response rate (ORR) was 45.16% (95% CI, 26.61%–63.72%), and the disease control rate (DCR) was 51.63% (95% CI, 32.98%–70.25%). The median progression-free survival was 7 months (95% CI, 4.27–9.73 months). For the toxic and side effects among the 31 patients, the numbers of the grade 3, grade 2, and grade 1 leukopenia were 1, 8, and 13, respectively. Meanwhile, 18 were grade 1–2 neutropenia, 17 grade 1–2 anemia, and 2 grade 1 thrombocytopenia. At the same time, alimentary canal reaction followed by nausea and vomiting was relatively modest and could be controlled. hTe serious damage of hepatic-renal function was not found. Conclusion: The chemotherapy of lobaplatin combined with docetaxel is effective on recurrent and refractory ovarian cancer with low side effects, which has advantages over the second-line chemotherapy protocols.

Percutaneous radiofrequency ablation (RFA) has been widely used in the treatment of malignant hepatic tumors and has achieved satisfactory effects.Complications after RFA have been taken seriously and the risk of the development of complications is closely associated with tumor location.It is a great challenge for physicians to perform RFA for hepatic tumors in high-risk locations due to related difficulties and risks.This article reviews the complications after RFA for hepatic tumors in high-risk locations and analyzes related control strategies.

NOK is a newly identified receptor protein-tyrosine kinase (PRTK) molecule that can promote tumorigenesis and metastasis. Previous data showed that NOK could activate the phosphatidylinositol 3'-kinase (PI3K) pathway in stable BaF3 cells. But how does NOK activate PI3K in cells remains unknown. It was showed that NOK physically interacted with the PI3K downstream effector Akt and enhanced its activation in human embryo kidney 293T (HEK293T) cells. Deletion mapping indicated that protein kinase B (Akt) was able to directly contact with the kinase domain of NOK. Inactivating the Akt kinase domain significantly reduced the intermolecular interaction between NOK and Akt, while constitutively active mutant of Akt apparently had a stronger interaction with NOK. NOK did not have an additive effect on insulin-mediated Akt activation. Overall, the results indicate that NOK might complex with Akt and directly activate PI3K/Akt signaling pathway.

ObjectiveTo retrospectively evaluate the efficacy and safety of zoledronic acid and sodium ibandronate in treating bone metastasis in breast cancer patients.MethodsThe study included 47 patients who were treated with zoledronic acid and sodium ibandronate respectively from Aug.2006 to Mar.2011. KaplanMeier curve and Log rank test were adopted to detect the difference in survival time of skeletal related event (SRE) and survival rate between patients treated with different medicine,and x2 test was uscd to rcveal thc rate difference of pain killing effects and adverse effects.Results 1.The total effective rate of pain killing was 88.9％ and 85％ respectively.The difference had no statistical significance(P =0.467).2.The 1,2 and 3-year-survival rate in zoledronic acid group and sodium ibandronate group was 88.7％,44.4％,24.2％vs 94.7％,40.5％,5.8％.The difference had no statistical significance(P =0.744).3.The 2,3,and 4-year-survival rate in zoledronic acid group and sodium ibandronate group was 70.4％,40.7％,23.1％ vs 85％,46.7％,17.5％.The difference had no statistical significance( P =0.994).4.The 1,2 and 3-year SRE-free overall survival rate of the group with metastasis first to bone only was 92％,50.8％,and 23.8％,while the rate of the group with first metastasis to visceral organs was 85.4％,21.4％,and 5.3％ ( P =0.012).5.The 2 and 3-year overall survival rate of the group with metastasis first to bone only was 95.8％ and 74.2％ respectively,while the rate of the group with first metastasis to visceral organs was 56.5％ and 10.1％ ( P ＜0.001 ).The difference of 4 and 5 had statistical significance.The difference of zoledronic acid group and sodium ibandronate group in rate of adverse effects had no statistical significance.Conclusions Compared to sodium ibandronate,zoledronic acid has no superiority in either delaying the occurrence of SRE or improving overall survival rate.The -2are similar in incidence of adverse effects and pain control.The prognosis of patients whose first presentation is complicated by metastasis to other organs is poor.

BACKGROUND: Currently,the research of posterior cruciate ligament (PCL) construction mainly focuses on the surgical technique or graft selection. However,studies on vascular regeneration after construction are few,especially those on allograft construction. OBJECTIVE: To observe the effect of vascular endothelial growth factor (VEGF) on vascular regeneration of reconstructed PCL with femur-anterior cruciate ligament (ACL)-tibia allograft in rabbits. DESIGN,TIME AND SETTING: The factorial design experiment was performed at the Orthopedics Laboratory of the Third Affiliated Hospital of Weifang Medical College from March 2006 to September 2007. MATERIALS: Sixty-eight adult female Japanese white rabbits,weighing (3.3?0.1) kg,were adopted. Twenty-three of them were used to excide the femur-ACL-tibia complexes to establish the animal model of PCL reconstruction with allograft. METHODS: Forty-five rabbits were randomly divided into 3 groups,15 rabbits in each group. In the control group,no additional treatments were applied. In the phosphate-buffered saline (PBS) group,0.2 mL of PBS was injected into the knee joint. In the VEGF group,30 ?g VEGF mixed with 0.2 mL PBS was injected into the knee joint. MAIN OUTCOME MEASURES: The immunological rejection of allograft was observed after reconstruction. Five rabbits were randomly selected in each group at 3,6,12 weeks,respectively,for immunohistochemistry staining; and the microvessel density of the medio-one-third ligament part of allograft was evaluated with the Chalkley scoring method. RESULTS: Forty-five rabbits were involved in the result analysis. There were no hydrops articuli or aneretic cartilage when every rabbit’s knee joint was opened. The gross morphology of the grafts was similar to normal posterior cruciate ligament. Immunological rejection,such as degeneration,necrosis,dilapsus or defluxion was not appeared. Plenty of good vascular tissue in the arthrosis could be seen in the VEGF group,but could not be found in the control group or in the PBS group. The microvessel density score of the allograft in the VEGF group was higher than that in the control group and PBS group (P
