Objective To analyse the imaging variety and characteristics of vertebral body with ischemic compression fractures.Methods 11 patients whose initial diagnosis was osteoporotic vertebral compressed fractures while the final diagnosis was ischemic vertebral compression fractures were followed-up.During their subsequent visit 11 cases were undergone radiographic examination and the morphologic and the characteristics of variety of the vertebral body with compressed fractures were observed under X-ray fluoroscopy in the different position.8 cases were undergone spiral CT scan.The all imaging data of 11 cases were analysed.Results The dynamic imaging findings of the compressed vertebral body in 11 cases were progressive vertebral collapse and kyphosis.The collapsed vertebral bodies were flat in morphology in 8 cases,biconcave in 3 cases.The vacuum cleft was present in all collapsed vertebral bodies.Conclusion The imaging features of ischemic vertebral compressed fractures are of certain characteristic.

ObjectiveTo observe the effects of acupuncture combined with massage on shoulder subluxation and motor function recovery of the upper extremities in patients with hemiplegia after stroke.Methods60 hemiplegic patients were randomly divided into two groups for treatment with acupuncture cooperates with massage or usual rehabilition, respectively. The recovery of the patient's shoulder subluxation and movement function of upper extremities were evaluated 2 months after treatment. ResultsThe shoulder subluxation and movement function of the upper extremities were improved after treatment with both therapies (P<0.01), and acupuncture cooperates with massage showed better effect (P<0.01). ConclusionAcupuncture cooperates with massage can facilitate the recovery of shoulder subluxation and motor function of the upper extremities after hemiplegia.

Objective To know about the influence of quality control based on Gantt chart on work quality and stress,so as to explore effective method of management suitable for them.Methods 52 nurses from the eastern zone of a three A-level hospital in Jiujiang City were randomly selected as the experimental group,they were implemented with Gantt chart management.Another 52 nurses from the western zone of the same hospital were selected as the control group,they were executed traditional experience-based management.The scores of quality of care and nurses stress were compared between the two groups.Results For the score of the quality of care,the experimental group was higher;,for the score of the nurses stress,the experimental group was lower in the overall sides,and the differences were significant except those of the working environment and equipment,which showed no significant difference between two groups.Conclusions Gantt management method can significantly improve the quality of care,moreover,effectively alleviate the nurses'stress.

Objective To evaluate reliability and validity the Chinese-version of chronic pain acceptance questionnaire-8(CPAQ-8).Methods The reliability and validity of CPAQ-8 was tested in 223 old patients with chronic pain.Result The Chinese-version of CPAQ-8 was (23.79±-5.23),AE was (12.84±4.96),PW was(10.97 ±2.90).Cronbach' s of CPAQ-8 was 0.853,and Guttmann Split-Half Coefficient was 0.843.Two factors were extracted by factor analysis through exploratory factor analysis,whose cumulative contribution was 58.217％.While confirmatory factor analysis showed probability level of the modified model was P=0.322,with indexes as follows: x2/df =1.124,GFI =0.979,AGFI =0,956,TLI =0.069,RMSEA =0.024,NFI =0.960,TLI =0.992,CFI =0.995.Conclusion Reliability and validity of CPAQ-8 were both well.

Objective To investigate work stress state of nursing home staff and to analyze the influential factors affecting work stress.Methods Stratified random sampling method was adopted to investigate 180 nursing assistants by self-designed questionnaire,Work Stress Scale(WSS),Simplified Coping Style Questionnaire and internal-external locus of control scale investigation.Results Totally 174 valid questionnaires were collected.Variance analysis revealed there were significant differences of age and other factors.Stepwise multiple regression analysis showed five variables entered the equation,including workexpenence education level number of the cared ages work scheduline coping stule and explain 56.7％ of the total variable.Conclusion Nurse managers should pay attention to and improve achievement sense and mental adjustment ability of nursing assistants,to build a well-organized support system to reduce the workload.

Objective To design an experiment for method-comparison and bias estimation of multi tests on multi instruments.Methods According to the procedure described by the NCCLS approved guideline EP9-A and improving the method of sample collection,we took 8 patient mixing samples each day to analyze all comparison tests on 11 auto-chemistry analyzer within following 5 days.The duplicates were assessed within the same run.The coefficient of correlation and average bias% were calculated,and the system errors at medical decided levels were assessed.Results Taking ALT as an example,the coefficients of correlation were between 0.994-1.000,and the average bias% were between-0.460%-4.927%,SE at 40U/L was-1.510-1.834 and SE at 300 U/L was-3.101-9.188.Conclusion In all tests that joined the comparison among the different instruments,28 tests were acceptable,2 tests were acceptable after modifying the coefficients,and AMY and LIP were not acceptable.

Objective To investigate the clinical effect of IFNα combined with mannan peptide in treatment of patients with HBeAg-positive chronic hepatitis B ( CHB ). Methods Eighty HBeAg-positive CHB patients with HBV DNA quantity ranging from 10 to 10 eopies/mL were enrolled and randomized into the treatment group and the control group ( n = 40 for each ). Patients in treatment group were given daily subcutaneous injection of IFNα-2b 5,000,000 U for 52 weeks, and received mannan peptide 10 mg per intravenous injection or 2. 5 mg per intramuscular injection for a total of 2 to 3 treatment courses (12 weeks for each). The control group received only IFNα-2b treatment. Liver function, serum markers of hepatitis B, HBV DNA quantity and blood tests were performed before the treatment and at 2, 4, 8, 16, 26 and 52-week during the treatment; and the adverse effects were recorded. Results The rates for ALT normalization, negative HBsAg, negative HBeAg, HBeAg seroconversion and negative HBV DNA were 91. 8% , 17. 5% , 52. 5% , 27. 5 % and 47. 5% at 52nd week in the treatment group, while those in the control group were 80. 0% , 12. 5% , 30. 0% , 10. 0 % and 25. 0% , respectively. There were significant differences in HBeAg-negative, HBeAg-seroeonversion and HBV DNA-negative rates between two groups (χ2 = 4. 178, 4.021 and 4.381, P < 0. 05 ) , and these indexes in the treatment group were increased to 57. 5% , 30. 0% and 50. 0 respectively at 52nd week after drug withdraw. White blood cells began to be elevated at 4th week and were restored to the normal levels at 8th week in the treatment group, while the count in the control was lower than the normal value even at 52nd week of the treatment with the average of (3.45±1. 18)×109/L. Conclusion Alpha-interferon combined with mannan peptide therapy is effective for patients with HBeAg-positive CHB, which may restore the declined peripheral WBC counts induced by interferon and improve the compliance.
