Objective To investigate the prevalence,radiological features and the association between HRCT changes and different diseases or clinical features in interstitial lung disease(ILD)caused by diffuse connective tissue diseases(CTD).Methods Retrospective analysis was performed based on the medical records of 412 in-patients with the diagnosis of diffuse connective tissue diseases from June 2003 to June 2005 in our hospital.268 cases were SLE,83 cases were SS,40 cases were DM/PM,21 cases were SSe.All patients had chest X-ray and the suspected cases had HRCT exam.The distribution of ILD among different diffuse CTD.the appearance between X-ray and HRCT appearances were compared.The correlation among HRCT appearance,different diseases and clinical features was studied.Results①In the 412 cases of CTD,ILD de- tected by HRCT was 9.7%(40 case in total),3,9% by X-ray.Among the 40 cases,DM/PM had the highest rate of ILD(25%),23.8% in SS,9.6% in SS and 6.3% in SLE.②The consensus rate between HRCT and X-ray was 40%.The rate of mis-diagnosis of ILD was 60% by X-ray.③The changes of interstitial involvement de- tected by HRCT were:ground glass change(41.0%),consolidation(32.8%),reticular change(16.4%)and hon- eycomb change(9.8%).The concomitant presence of two of the above changes were very common.④More level respiratory symptoms such as cough,panting,chest distress and chest pain and high level of complement were observed in patients with ground glass and consolidation changes,while high CRP level was seen in patients with consolidation and honeycomb changes(P

Objective To explore the application of Artglass material in aesthetical restoration. Methods A total of 2196 restoratio ns, including 1963 veneers and 233 crowns, were made for 335 patients, and clini cal results were examined and recorded one by one. The related problems were dis cussed. Results There was significant improvement on cosmetics in most of the 2196 restorations; 44 restorations in 21 patients were failed, re sulting in a failure rate of 2%. The failure cases were repaired with Chrisma ma terial or remade with Artglass material. Conclusion Artglass ma terial has satisfactory prosthesis effects in aesthetical restoration. The bondi ng process and occlusion adjustment are important and should be specially notice d.

In order to study the spectral reflectance differences of Glycyrrhizae Radix under different growth conditions and lay the foundation for quantitative monitoring of Glycyrrhizae Radix remote sensing images, spectra of Glycyrrhiza species under different growth period and different varieties and different regions were measured by a portable spectrometer. The results showed that the reflectivity of annual G. uralensis was obviously higher than that of the two years plant in the visible light band own to the contents of crown layer chlorophyll. The reflectivity of two years G. pallidiflora was higher than that of G. uralensis in the near infrared band own to the leaf area index and the content of leaf water. The red edge spectrum of annual plant fluctuated largely than that of two years plant due to vegetation coverage and leaf area index. G. pallidiflora grew well than G. uralensis. Under different regions of the Glycyrrhiza species, spectral data analysis showed that within a certain range, the average annual precipitation and average annual evaporation were the major factors to affect the differences of Glycyrrhiza species spectral data under different regions owe to the leaf water content, the higher leaf water content, the lower spectral reflectance. The principal component analysis and continuum-removed method of the spectral data under different regions found that, within a certain range, the average annual precipitation and average annual evaporation were the major factors caused by the differences of Glycyrrhiza species spectral data under the different regions, Glycyrrhiza species spectral similarity related to the spatial distance.

OBJECTIVETo analyze the reliability and validity of the Fatigue Self-assessment Scale (FSAS).

METHODSThe scale was applied among the participants assigned to 4 groups, the differences in types, degrees and characteristics of fatigue of them were compared, and the reliability and constitutional validity of ESAS were assessed by internal consistency analysis, exploratory factor analysis and confirmatory factor analysis using the statistical software of SPSS and LISREL.

RESULTSStatistical differences of types, degrees and characteristics of fatigue presented in the participants of the 4 groups. The Cronbach's alpha of various factors in the scale were 0.772-0.908; the indexes for the section of assessing type, and degree of fatigue were RMSEA=0.065, NNFI=0.95, CFI=0.96; and those for the section of assessing characteristics of fatigue were: RMSEA=0.10, NNFI=0.93, CFI=0.96.

CONCLUSIONThe FSAS has good differentiability, reliability and constitutional validity for assessing the type, degree and characteristics of fatigue in various populations. In order to explore the relationship of TCM syndrome patterns with the type, degree and characteristics of fatigue, its future application for evaluation of fatigue and intervention effect of anti-fatigue should be combined with TCM syndrome differentiation.

Objective To analyze causes for postoperative coxa vara and anti-rotation nail cutting-out after treatment of brittle femoral intertrochanteric fractures with proximal femoral nails ( PFN ).Methods An retrospective study was done on 227 patients with intertrochanteric fracture treated with PFN from June 2006 to February 2009. The causes for postoperative coxa vara and anti-rotation nail cutting-out were analyzed. Harris score was used to evaluate the functional recovery of the hip joint. Results Of all, 221 patients were followed up for 12-48 months (mean 23 months) and six patients were died from serious internal disease within one year. According to Harris evaluation system, the results were excellent and good in 183 patients, fair in 30 and poor in 14. Postoperative coxa vara and anti-rotation nail cuttingout occurred in 16 patients, eight of whom received reoperation to remove internal fixation and skeletal traction at abducent position and the other eight received prosthetic replacement. Conclusions Treatment of proximal femoral fracture with PFN requires a high precision of reduction and operation. Many factors including lateral cortical bone conditions of tuberosity, postoperative patient's cognitive condition,use of improved Jensen-Evans classification and Singh's classification may affect operation outcome.
