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.

Objective To study the application of negative pressure drainage on nasal septum reconstructomy by endoscopy.Methods Totally 80 patientswith nasal septum deviation in our hospital from May 2014 to March 2015 were randomly divided into the observation group and the control group.All patients were given nasal septum reconstructomy by endoscopy,and patients of the observation group were given negative pressure drainage after surgery while the patients in control group were given traditional nasal cavity filling postoperatively.Observed the subjective symptoms,degree of disease and complications of patients 12 hours and 24 hours after surgery.And the clinical curative effect of the two groups were compared and analyzed 1 week after the surgery.Results The subjective symptoms of the observation group was obvi-ously better than the control group 24 hours after the surgery with statistically significant difference (P <0.05).And the degree of disease in observation group had significantly improved,and the nasal mucosa edema ratio of level 0 was 40%,which was significantly higher than 10% in the control group (P <0.05).The total effective rate was 97.50% in the observation group 1 week after surgery and it was 80% in the control group,and there were significant difference between the two groups (P <0.05).The incidence of complications in the observation group was 2.50%,which was significantly less than 20% in the control group (P <0.05).Conclusion The application of negative pres-sure drainage on nasal septum reconstructomy by endoscopy could effectively relieve the pain of patients and reduce complications,and its prognosis effect is better.

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 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.

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.
