Methods One hundred and ten NPC patients undergoing radiotherapy participated in the investigation by the Herth Hope Index(HHI)and the Functional Assessment of Cancer Therapy-head and neck scale(FACT-H&N),to look into the correlations between their hope and QOL.Result The scores on hope and NPC for the QOL patients during radiotherapy were(34.80±2.64)and(91.34±13.19),respectively and they were positively correlated(r=0.253,P<0.01). Conclusions The hope of the NPC patients is at the medium level.Their hope is positively correlated with QOL.The higher level the hope is,the higher the QOL.

Objective To observe the clinical efficacy and safety of Shuxuetong in treatment of paroxysmal atrial fibril-lation in patients with chronic pulmonary heart disease. Methods A randomized single-blinded study was performed. A to-tal of 91 patients with paroxysmal atrial fibrillation and chronic pulmonary heart disease were randomly divided into treat-ment group (n=45) and control group (n=46). The treatment group was received Shuxuetong and clopidogrel treatment for 14 days. The control group was given routine treatment plus clopidogrel 75 mg orally. The average time of cardioversion of parox-ysmal atrial fibrillation was detected within 48 hours. The cardioversion rate of paroxysmal atrial fibrillation and the total effi-ciency were detected after14 days. The serum D-Dimer was detected before and 14 days after treatment . Liver and kidney function and adverse drug reactions were also detected. Results There was no significant difference in average time of car-dioversion of paroxysmal atrial fibrillation in 48 h between two groups (h:12.62±2.32 vs 13.32±2.25,t=1.461). The cardiover-sion rates were 86.67%(39/45) and 82.22%(37/45) at 48 h and 14 d in treatment group, which were significantly higher than those of control group [69.56%(32/46) and 60.87(28/46)]. The D-Dimer at 14 d after treatment was significantly lower in treatment group [(2.05±0.34)mg/L] than before treatment[(2.61±0.27)mg/L], also than that of control group[(2.53±0.31)mg/L]. There were no abnormal liver and kidney function and no adverse reactions between two groups. Conclusion Shuxuetong can significantly prevent the recurrence of paroxysmal atrial fibrillation in patients with chronic pulmonary heart disease, and help to reduce the risk of thromboembolism. It is safe and effective.

Objective:To observe the effects of orbital bone density on the stress distribution of implant-bone surface.Methods:The 3D finite element analysis craniofacial model with eight HU values(300 -1 0 000)was established.A force of 20 N along the im-plant axis was applied on the model.The stress values and distribution were calculated and analyzed.Results:The peak of stress val-ue and displacement discreased as HU value increased.In the range of HU value 800 -1 000 HU,the peak of stress value and dis-placement of bone interface did not significantly change with the increasing of HU value.Conclusion:Orbital bone density is an im-portant factor on orbital implant failure when HU value below 800.

Background The measurement of retinal nerve fiber layer (RNFL) by Cirrus optical coherence tomography (OCT) has been applied widely in ophthalmology.However,previous assessment of RNFL is based on spatial measurement,while the evaluation based on optical characteristics of OCT can offset the shortcomings of spatial measurement in some eye diseases.Objective This study was to analyze the optical characters of RNFL measured by OCT and its correlation with age in healthy Chinese individuals.Methods Four hundred and six normal healthy subjects were collected in Shanghai Shibei Hospital from June 2011 to June 2012,with the age of 40-83 years old.Macular RNFL was unilateral imaged using a Cirrus OCT device with 5 line raster macular scan mode under the approval of Ethic Committee of Shanghai Shibei Hospital and informed consent of subjects.A customized software was used to measure RNFL optical characters,including absorbance (A value) and attenuate coefficient.The difference of the measured parameters in different genders was compared.The correlations between RNFL optical characters and age were analyzed by linear regression analysis.Results The data of 353 eyes were included in the final outcomes.The RNFL thickness,A value and attenuate coefficient were (35.1 ±4.4) μm,121.6 ±5.3 and 2.06 ±0.25,respectively.RNFL thickness and A value showed significantly negative correlations with age (r=-0.487,-0.571,both at P＜0.01) with the regression equation Y=-0.17 X+45.23 and Y=-0.24 X+ 135.82,while a positive correlation was found between the attenuate coefficient and age (r=0.368,P＜0.01) with the regression equation Y=0.01 X+1.63.RNFL thickness and A value showed weaker positive correlations with OCT signal intensity (rs =0.128,P =0.016;rs =0.284,P＜0.01),but no remarked correlation was seen between the attenuate coefficient and OCT signal intensity (rs =-0.053,P=0.319).Conclusions Age of subjects affects the parameters of OCT optical characteristics in normal populaition.Age-related RNFL change in optical characters of OCT should be considered before concluding optical parameters.
