The process of tumorigenesis,local invasion and distant metastasis will produce a series of molecular changes,these genetic mutation or abnormal expression of molecules play a promoting role in hypercoagulation.At the same time,hypercoagulation also increases the risk of tumor progression.It is important to understand their specific processes and the molecular role,and it can provide theoretical basis for better management of patients,and has significance for developing more effective and security new anti-clotting drugs.

Objective To analyze the application and funding for projects in radiation oncology from National Natural Science Foundation of China ( NNSFC ) from 2006 to 2015. Methods To collect the funding information in radiation oncology from NNSFC from 2006 to 2015, a computerized search was performed in the ISIS system using a subject code of H1610 and a keyword of radiation oncology. Analyses were performed in distribution of research fields, the geographical distribution of applicants, and the properties of institutes/universities the applicants were affiliated with. Results In the last decade, a total of 435 projects in the field of radiation oncology were funded with 180 million yuan. Most projects were funded by general, youth, and regional foundation, which covered the highest proportion of NNSFC. For a single project, the amounts of funding from general, youth, and regional foundations were 530, 220, and 400 thousand yuan, respectively. The institutes/universities the NNSFC?funded projects were affiliated with were located quite close to each other. The top 10 institutes/universities in terms of the number of NNSFC?funded projects covered 53% of projects. In all projects, 88% studied basic science, which covered many hot topics in oncology including biological effects of radiotherapy, microenvironment, and stem cells. A small number ( 12%) of projects focused on physics. Top 3 cancers in terms of the number of projects and the amount of funding were lung cancer, nasopharyngeal carcinoma, and esophagus cancer. Conclusions In the last decade, the field of radiation oncology has stable increases in the number of NNSFC?funded projects and the amount of funding. The NNSFC?funded research teams are unevenly distributed, most of which are located in East China. The most popular topic in basic science studies is about biological effects of radiotherapy.

AIM: To explore the effects of high D-glucose on the mRNA and protein expression of lectin-like oxidized LDL receptor-1 (LOX-1) in endothelial cells and to study the possible mechanism by which diabetes is easily accompanied by vascular diseases. METHODS: Cell morphology was observed with inverted phasecontrast microscope. LOX-1 mRNA was detected by quantitative reverse transcription polymerase chain reaction in vascular epithelial cells cultured with different concentration D-glucose (7 5, 15 or 30 mmol/L) or with the same concentration D-glucose (15 mmol/L) in different time (0, 12, 24, 48, 72 or 96 h), LOX-1 protein expression was also examined by immunohistochemisty. RESULTS: Cells, exposed to high concentration D-glucose, were crude with clear profiles and bright granules in the plasma. Different high concentration D-glucose could induce LOX-1 mRNA expression and the effect of 30 mmol/L glucose on LOX-1 mRNA was the most significant (P

0.05). Ac-cording to the classification criteria of ARIA in 2001, 26 children suffered from intermittent A(R22 mild cases,4 moderate-severe cases),while 22 suf-fered from persistent AR(10 mild cases,12 mod-erate-severe cases). Forty percent patients with AR also had bronchial asthma. Domestic decora-tion was an important factor in the induction of AR and 27.1% of the children with AR had inher-ent predisposition. CONCLUSION The prevalence rate of AR in children aged from 9 to 10 in Nanjing is 5.1 %. Strategy of prevention and treatment of AR should beworked out according to the epidemic feature of AR.

Objective To investigate the role of deferoxamine pretreatment for hepatic ischemia reperfusion injury in liver auto-transplantation in rats. Method Murine liver auto-transplantation model was established. Ninety six male Sprague-Dawley rats were randomly divided into three groups: 32 rats in deferoxamine pretreatment group (D), 32 rats in control group with aqua pro injection pretreatment(C) and 32 rats in sham-operation group (S). The animals were killed at 30 min, 2 h, 6 h, 24 h after operation respectively. ALT and AST level, superoxide dismutase (SOD) and malondialdehyde (MDA), liver histological change(HE), the protein expression of HIF-1α、TNF-α and IL-1 were measured. Results At 30 min, 2 h, 6 h, 24 h after operation, the levels of ALT,AST,MDA and the expression of IL-1 protein and TNF-α protein were higher in group C than group D significantly,while the expression of HIF-1α and SOD were higher in group D [SOD(411±70; 384±53; 379±46)、H1F-1α(0.0413±0.0040; 0.0684± 0.0032; 0.0583±0.0032; 0.0491±0.0026)] than group C significantly (P<0.01) [SOD(341±21; 323±25; 303±25)、HIF-1α (0.0254±0.0024; 0.0312±0.0022; 0.0381±0.0022; 0.0257± 0.0015)] (F>59.881;P<0.01). Conclusion The up-regulated expression of HIF-1α, decreased liver lipid peroxidation injury and TNF-α and IL-1 levels, may be involved in the mechanism hy which deferoxamine pretreatment protects liver from ischemia reperfusion injury in rats' liver auto-transplantation.

Objective To discuss the diagnosis and surgical treatment of solid pseudopapillary tumor (SPTP) of the pancreatic head.Methods From January 2008 to August 2013,the clinicopathological data of 12 patients who were diagnosed and surgically treated in our hospital for this condition were analyzed retrospectively.Results There were 11 women and 1 man,the mean age was 28.7 years,with a range from 11 to 43.The mean diameter of the tumor was 7.5 cm(2 ～ 15 cm),6 of 12 of these tumors were more than 10 cm.Seven patients underwent pancreaticoduodenectomy,2 duodenum-preserving pancreatic head resection,2 local resection of tumor,1 palliative resection,1 pancreaticoduodenectomy combined with resection of part of the portal vein.All the diagnoses were confirmed by postoperative histopathology.In a follow-up which ranged from 3 to 65 months,all the patients were alive with no evidence of disease recurrence.Conclusions Most of the SPTPs of the pancreatic head were huge.The diagnosis was difficult.Complete tumor resection is the best treatment.

Inrecentyearsmanytargetedagentstreatinggastriccancerhavebeenevaluatedinclinical studies.Trastuzumab,an anti-HER-2 monoclonal antibody,has shown activity against HER-2-positive gastric cancer and become the first targeted agent approved in gastric cancer.Drugs targeting epidermal growth factor receptor,including monoclonal antibody and tyrosine kinase inhibitor,bring survival benefit to patients with gastric cancer.Addi tionally,vascular endothelial growth factor inhibitors are also under investigation.Other targeted agents are in preclinical or early clinical development,such as m-TOR inhibitors and c-MET inhibi-tors.

Objective To evaluate the procedure and the therapeutic efficacy of duodenumpreserving pancreatic head resection (DPPHR) in treating benign lesions in the head of the pancreas.Methods From February 2003 to August 2011,DPPHR was performed in 21 patients with benign lesions in the head of the pancreas.Thirteen patients were male and eight were female.Age ranged from 30 to 48 years,and the lesions ranged from 2.0 cm to 5.6 cm in diameter.Posterior superior pancreaticoduodenal artery was conserved in all patients.Results There was no hospital death.Pancreatic fistula was the main and the most often morbidity,occurring in 33.3％.After operation all patients with preoperative abdominal pain were completely pain free.Preoperative hypoglycemia in 2 patients turned to eugycemia.There was no recurrences report during following up.Concl~ions DPPHR was safe and effective in treating benign lesion in the head of pancreas.It was important in preserving blood supply to the duodenum by posterior superior pancreaticoduodenal artery.
