Objective To explore the clinical effect of the endoscopic electrocoagulation combined with nasal micro packing in the treatment of refractory epistaxis .Methods 120 patients with refractory epistaxis were selected as the research subjects ,and they were divided into two groups by the single blind randomly methods ,60 cases in each group.The control group was given vaseline gauze for hemostasis of nasal cavity ,and the observation group received endoscopic electrocoagulation combined with nasal packing hemostasis micro treatment .The cure rate ,the incidence of complications ,recovery of nasal mucosa of nasal ventilation time , recovery time , the total amount of bleeding , pain score and recurrence rate of the two groups were compared .Results The cure rate in the observation group was 96.67%,which was significantly higher than 81.67% in the control group(χ2 =6.988,P<0.05).The incidence rate of complications and pain score in the observation group were 8.33%,(3.65 ±1.09)points,respectively,which were significantly lower than 21.67%,(5.23 ±1.72) points in the control group (χ2 =4.183,t =6.010,all P<0.05).The total amount of bleeding significantly reduced (t=6.344,P<0.05),the recovery of nasal ventilation time and recovery time of nasal mucosa significantly decreased (t=7.119,6.183,all P<0.05).The patients were followed up for 6 months,the recurrence rate in the observation group was 1.67%,which was significantly lower than 11.67%in the control group(χ2 =4.821,P<0.05).Conclusion The endoscopic electric coagulation combined with nasal micro packing in the treatment of refractory epistaxis has significant effect ,it can effectively promote the recovery of patients,reduce complications and recurrence ,the prognosis is good .

Objective To observe the expression of AdipoQ in Sj?gren's syndrome (SS) mice and its role in inflammation was investigated by recombinant gene transfection study in vivo. Methods As spon-taneous SS mice model, a total of 30 NOD mice were divided into 3 groups randomly: recombinant adenovirus (rADV-AdipoQ) group, normal saline control and simple adenoviruses (control group). The submandibular gland morphology, histopathological grading and the level of serum tumor necrosis factor-α (TNF-α), AdipoQ was compared between the three groups. The expression of AdipoQ on mice submandibular gland was assessed by means of semi-quantitative reverse transcriptase polymerase chain reaction. Results The submandibular glands of the mice of the control group were destructed, with focal lymphocytic infiltration and acinus atrophy. Compared with control model groups, the serum TNF-α and salivary gland AdipoQ expression was significantly down-regulated in the rADV-AdipoQ group [(248 ±30) vs (162 ±73) ng/ml] (P<0.05). Conclusion AdipoQ gene transfected SS mice can significantly improve the morphological features of tissues and decrease the concentration of TNF-αin serum, in addition, it can effectively inhibit inflammation, decrease the degree of protein and AdipoQgene expression. So the AdipoQ may be the protective gene in SS mice.

Objective To explore the effects of HAVCR2 siRNA on apoptosis and cell cycle in the radiation-caused genomic instable liver cells.Methods RNAi was used to inhibit HAVCR2 gene transcription.Cellular apoptosis and cell cycle distribution were detected by flow cytometry (FCM).Expression of p53 gene was assayed by real time fluorescence quantitative PCR.Results HAVCR2 gene was effectively inhibited by RNAi (t =19.21,P < 0.05).After siRNA transferring,cell apoptosis (t =3.65,P < 0.05) and p53 gene expression (t =4.82,P < 0.05) were decreased,and G2-phase arrest was induced(t =-3.41,P < 0.05).Conclusion HAVCR2 siRNA can decrease the generation of apoptosis in the genomic instable liver cells and blocks the cells at G2 phase.

Objective To investigate the changes of proteomics in serum of Sprague-Dawley(SD) rats after accumulated irradiation with 137Cs γ-rays.Methods A total of thirty mature SD rats were randomly divided into three groups:0.2 Gy group,2 Gy group and healthy control group.Rats were irradiated at a dose rate of 0.336 mGy/min for 10 d and 20 d continuously.Isobaric tags for relative and absolute quantitation (iTRAQ) was used to analyze the different protein expression in serum of irradiated rats.Gene Ontology,KEGG pathway and protein-protein interaction network analysis were conducted using softwares.Results In total,363 protein spots were identified.Twenty nine proteins were differentially expressed in both groups compared with control,of which 10 proteins were up-regulated and 19 proteins were down-regulated.Based on the information of GO categories,these differentially expressed proteins were mainly located in the cytoplasm and membrane concerning the function of binding and catalytic activity.Analysis with the PAJEK software demonstrated that 16 differentially expressed proteins could form a complicated interaction network where glutathione S-transferase P1 (GSTP1),phosphoglycerate kinase 1 (PGK1) and protein disulfide-isomerase (PDI) might be key nodes.Conclusions Accumulated irradiation can induce differentially expressed proteins in serum of irradiated rats.Analysis on functional roles of the screened proteins GSTP1,PGK1 and PDI may provide insight into further mechanistic investigations and underlying molecular biomarkers induced by accumulated irradiation.

Objective To analyze the current situation and developing trend of utilizaion of medical insurance drugs.Methods Data were collected from Suqian Hospital.Drug Utilization Analysis System and DDD were taken as the basic unit of measurement.Results The consumption of cost,DDDs and variety of type A medical insurance drugs were rising year by year,but the proportion in total was in declining trend.When analyzed according to DDDc,the type A,non medical insurance drugs and the type B ranked the first,the second and the third place during the 2009-2010,the DDDc of type A was lower than the non medical insurancedrugs and the type B.For example,the DDDc of type A was 3.32 yuan/day,the DDDc of the non medical insurance drugs and the type B was 15.04 and 15.97 yuan/day respectively.Conclusion Analyzed in respect to DDDs,the protortion of type A was in high level and the type B was in low.But analyzed in respect to the comsumption cost,the protortion of type B was in high level and the type A was in low.

Objective To explore the effects of accumulated 60CD,γ-ray irradiation on small molecular metabolites in rats urine.Methods Ten healthy male SD rats were irradiated by 60Co γ-rays in 5 days and the accumulated doses were 0,0.2,0.4,0.6,0.8,1.0 Gy,respectively.The metabolites in urine of different groups were measured with 1 H-NMR combined with principal components analysis (PCA) and partial least square discriminate analysis (PLS-DA). Results The metabolites in rat urine were obviously changed after irradiation. Compared with control group,the amount of acetoacetate decreased after irradiation(t =29.7 -30.7,P < 0.05 ),but its relative level was stable when the dose increased ( P > 0.05 ).Meanwhile,the relative level of hippuric acid increased ( t =4.4 - 21.6,P < 0.05 ) especially when the accumulated dose was higher than 1 Gy (t =21.6,P<0.05). The relative level of proline,taurine and trimethylamine-N-oxide increased after irradiation with the same trend( t =3.5 - 13.4,4.7 - 11.5,2.9- 12.7,P<0.05). Conclusions The acetoacetate,hippuric acid,proline,taurine,and trimethylamine-N-oxide may be applicable for biomarkers of accumulative irradiation on rat.
