Objective Gambogic acid ( GA) can suppress the growth of multiple tumor cells , including gastric carcinoma , hepatoma , hematologic neoplasms and breast carcinoma , but there have been few reports about its effect on urologic neoplasms .This study was to investigate the possible mechanisms of GA inducing bladder cancer cell apoptosis and cell cycle arrest . Methods We cultured human bladder cancer BIU8-7 cell lines in vitor and treated the cells in the logarithmic growth phase with isotonic saline solu-tion (negative control)or GA at the concentrations of 1.0, 2.0, and 3.0μmol/L, respectively.We determined the expression of the Caspase-3 protein in the tumor tissue using the immunohistochemical S-P method and detected GA-induced apoptosis of the bladder cancer cells and cell cycle changes by flow cytometry . Results The expressions of the Caspase-3 protein were 4.28 ±1.86, 5.03 ± 0.78, and 6.47 ±1.31 in the 1.0, 2.0, and 3.0μmol/L GA groups, respectively, significantly higher than 2.13 ±1.27 in the nega-tive control (P<0.05).Flow cytometry showed a gradual decrease of the cells in the G 0/G1 phase and a gradual increase in the G2/M phase , but no obvious change in the S phase . Conclusion Gambogic acid can promote the apoptosis , arrest the cell cycle , and in-hibit the proliferation of bladder cancer cells by increasing the expression of the Caspase -3 protein.

Objective:To search for a method for radical resection of pancreatic and duodenal malignancy involving the mesentery root and for the long post-operation survival of patients.Methods:From Jan.2004 to Aug.2006,a total of 26(16 male and 10 female. aged 27-70)patients with pancreatic and duodenal malignancy involving the mesentery root were treated in our department.The patients included 3 with duodenal malignancy and 23 with pancreatic malignancy.Curative resection was performed by the extended pancreaticoduodenetomy(Whipple procedure)combined with mesentery root resection(MRR)for all patients.The outcomes,safety and the post-operation survival rate were analyzed retrospectively.Results:Thirteen patients were treated with Whipple procedures combined with MRR,9 were treated with partial portal vein/superior mesenteric vein(PV/SMV)and reconstruction of the vessel,and 4 patients received pre-shunt between PV and SMV with artificial vessel graft before the extended Whipple and MRR procedures.The operation time was 2.5 to 7(4.4?1.1)hour,and blood loss was 300 to 5 000(1892?1414)ml with the blood transfusion of 0 to 5 600(2 100?1 586)ml.There was no death in our group and 7(27%)had post-operation complication.The post-operation hospital stay was 10 to 30 days.The pathologic examination showed negative surgical margins for all specimens.The tumor size was 4 to 10 (6.17?2.03)cm.After a follow-up of 9 to 38 months,the pain was relieved in all patients.One of the 3 patients with duodenal adenocarcinoma had liver metastasis at 10 months after operation,and the other 2 survived 10 months and 27 months without evidence of tumor reccurence.The patient with pancreatic micro-adenocarcinoma died of local reccurence 9 months after operation.The patient with neuroendocrine carcinoma died of organ failure 24 months after operation.The patient with lymphoma have survived for 24 months after operation.The 1-year and 2-year accumulated survival rates in the 20 cases with pancreatic ductal cancer were 86.6% and 45.6%. respectively.Conclusion:The extended Whipple procedure with MRR is safe and effective.It can obtain R0 resection in patients with malignant tumors(over 5 cm in diameter)in the head,neck and uncinate process of the pancreas and duodenal.

OBJECTIVETo investigate the morphological features of the perforator from the first plantar metatarsal artery, so as to provide anatomic basis for the reconstruction of soft-tissue defects of the forefoot.

METHODSThe first metatarsophalangeal joint was chosen as the landmark on 30 human cadaveric feet prefused with red latex. The following contents were observed under surgical magnifier: (1)The origin, courses,branches,distribution of the perforator of the first plantar metatarsal artery; (2)The anastomoses among the perforator of the first plantar metatarsal artery and other arteries on the medial aspect of the foot. Simulated operation was performed on one fresh specimen.

RESULTSThe perforator of the first plantar metatarsal artery passed through the space between the tendon, the abductor hallucis and the first metatarsal bone, and its entry point into the deep fascia was located (2. 3 ± 0.7 ) cm proximal to the first metatarsophalangeal joint. The perforator anastomosed with either the medial tarsal artery, the medial anterior malleolus artery or the branch of the medial plantar artery on the superior margin of the abductor hallucis, forming a longitudinal arterial chain,through which small branches were given off to the skin of the medial aspect of the foot. The perforator was( 1. 1 ± 0.2) mm in diameter and(3.2 ± 0.2) cm in length.

CONCLUSIONThe flap based on the perforator of the first plantar metatarsal artery can be harvested as an axial flap to repair the defects of soft tissue on the forefoot.

The most toxic DNA damage is DNA double strand breaks (DSBs), which are mainly repaired by non-homologous end joining (NHEJ). DNA-dependent protein kinase (DNA-PK) belongs to phosphatidylinositol-3-kinase-related protein kinase family (PIKK) and plays a key role in NHEJ. DNA-PK is overexpressed in a variety of cancer cells and is related to the occurrence, development and drug resistance of malignant tumors. In this article, the representative DNA-PK inhibitors with anticancer effects are reviewed, in order to provide a reference to discovery novel DNA-PK inhibitors.
