Objective To evaluate the biomechanical characteristics of the long U-shaped hollow pedicle screw system for percutaneous fixation of thoracolumbar fractures.Methods Models of vertebral compression fracture were created by flexion in 8 fresh cadaveric samples of thoracolumbar spine.The models were divided into 2 equal groups according to the fixation system applied.In group A conventional pedicle screws were used while in group B long U-shaped hollow pedicle screws were used.The yield compressive strength,axial compression stiffness,bending stiffness,torque and torsional stiffness of all the fixated spines in the 2 groups were tested by the bio-mechanical electrical measurement and compared as well.Results The conventional pedicle screws and long U-shaped hollow pedicle screws showed no significant differences regarding yield compressive strength (3450.02 ± 110.03 MPa vs.3430.04 ± 102.12 MPa),axial compressionstiffness (407.52 ± 33.02 N/mm vs.395.04 ± 26.46 N/mm),bending stiffness (305.14 ± 26.53 N · cm/Degvs.295.12±23.80 N · cm/Deg),torque (6.45±0.25 N · m vs.6.25±0.21 N · m) or torsional stiffness (0.54±0.04N·cm/Degvs.0.52±0.03N·cm/Deg) (P＞ 0.05).Conclusion The long U-shaped hollow pedicle screw system can satisfy the biomechanical requirements for fixation of thoracolumbar fractures and can function as well as the conventional pedicle screw system.

Objective: To investigate the relationship between attributional style and personality. Methods: We measured undergraduates with Attributional Style Questionnaire(ASQ)and Sixteen Personality Factor Questionnaire(16-PF).Results: Students with high-sensitivity, high-insecurity, high-tension, anxiety, not tough poise and low marks in Mental Health are apt to have negative attributional style. These personalities are the nuclear personalities of negative attributional style. Students with high-suspiciousness, high-insecurity,anxiety and low marks in Academic Achievement and Adjustment are apt to attribute fatefully. Conclusion: The nuclear personalities for negative attributional style are high-sensitivity, high-insecurity, high-tension, anxiety, not tough poise and low marks in Mental Health.

Objective: To investigate the effect of oat on blood glucose、insulin and serum lipid in aged patients with type-2 diabetes mellitus.Methods: Blood glucose(FBG,PBG),insulin(F-INS,P-INS) and serum lipid(TG,TC) were determined in eighty aged patients with type-2 diabetes mellitus before and after 50-100 g oat intake. Results: FBG,PBG and P-INS were decreased significantly(P

Objective To investigate distributions and drug resistance of pathogens in cirrhotic ascites comphcated with spontaneous bacterial peritonitis (SBP). Methods Results of bacterial culture and drug sensitivity tests of 117 aacitie specimens from cirrhotic patients with SBP were analyzed retrospectively. Results From the 117 ascitie specimens, 117 bacterial strains were isolated, among which 71 (60.68%)were gram-negative bacteria, 45 (38.46%) were gram-positive bacteria. The isolated strains were highly resistant to antibacterial agents, especially for Escherchia coli and Staphylococcu, the resistances to most antibiotics were above 60%. Conclusions High drug resistances were common for pathogenic bacteria in aacites of liver cirrhosis patients complicated with SBP.

Objective To investigate the efficacy of conservative treatment with laparoscopy for patients with ectopic pregnancy.Methods From January 2000 to December 2005,76 patients with ectopic pregnancy received conservative treatment by laparoscopy in our hospital.The data of the patients were analyzed retrospectively.Results In this series,fenestration of the Fallopian tube was performed on 42 cases,salpingostomy on 21,fimbrial expression on 8,and segmental resection and end-to-end anastomosis on 5.Salpingography showed that the Fallopian tube was patent after the operation in all of the patients.The mean operation time was(58.5?19.4) minutes(ranged from 35 to 105).The serum level of ?-hCG decreased to a normal range in 3 weeks postoperation.Follow-up was available in 61 cases for 1 year,during which 35 of the cases(57.4%,35/61) had intrauterine pregnancy;2(3.3%) had spontaneous abortion,and 2(3.3%) showed ectopic pregnancy;the other 22(36.1%) had no pregnancy.Conclusions Conservative treatment by laparoscopy is safe and effective for ectopic pregnancy.To avoid repeated ectopic pregnancy,?-hCG monitoring after the operation is necessary.

Objective To observe and analyze the effect of neoadjuvant chemotherapy on locally advanced non-small cell lung cancer tumor markers and lymphocyte subsets of different pathological type .Methods A total number of 40 NSCLC patients which received neoadjuvant chemotherapy and 20 normal people were selected in our study .To compare the differences of CEA ,CA-125 , CYFRA21-1 and lymphocyte subset in NSCLC pantients with adenocarcinoma or squamous cell carcinoma and the the differences of CEA ,CA-125 ,CYFRA21-1 and lymphocyte subset in patients with different clinical effect .Results (1) The CEA ,CA-125 ,CY-FRA21-1 in pantients with adenocarcinoma or squamous cell carcinoma were both higher than normal people .The CEA level in pa-tients with adenocarcinoma was higher than squamous cell carcinoma ,while the CA-125 and CYFRA21-1 in squamous cell carcino-ma were higher than adenocarcinoma .The CD3+ ,CD4+ ,CD8+ ,CD4+ /CD8+ in pantients with adenocarcinoma or squamous cell carcinoma both had obvious differences with normal people .But there were no obvious differences between patients with adenocarci-noma and squamous cell carcinoma .(2)There were 18 cases of CR+ PR while 22 cases of SD+ PD .The CA-125 and CYFRA21-1 were decreased in patients of squamous cell carcinoma with clinical effective while the CEA and CYFRA 21-1 were decreased in ade-nocarcinoma with clinical effective .The CD3+ ,CD4+ ,CD4+ /CD8+ increased and CD8+ decreased in patients of squamous cell car-cinoma or adenocarcinoma with clinical effective .Conclusion The tumor marker and lymphocyte subsets values had obvious differ-ences in adenocarcinoma and squamous cell carcinoma .Both tumor marker and lymphocyte subsets were useful in diagnosis .

Magnetic Resonance Imaging (MRI) can form a three-dimensional positioning anatomical imaging.By comparing the tumor volume and signal intensity changes,there is great value of MRI in the assessment of the efficacy of cervical cancer.With the development of imaging,magnetic resonance diffusion weighted imaging (DWI),magnetic resonance spectroscopy (MRS) can provide qualitative and quantitative information of the cellular level,which reflects changes in the treatment of tumor cells.Magnetic resonance imaging can predict early locally advanced cervical cancer neoadjuvant chemotherapy,thus providing an important basis for individualized treatment of patients.
