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 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 the degenerative changes in the inner rat retina after photic injury. Methods After 24 hour-dark adaptation, sixty Lewis rats were exposed in a ventilated green plexiglass chamber that transmitted continuous green light between 480-520 nm with an intensity of 900～1 000 lx. After 24-hour exposure, the rats stayed in darkness and were sacrificed after 1 day, 3,7 or 14 days. The neurons in the inner retina were marked by immunohistochemical technique and observed by light and electronic microscope. Results The apoptotic photoreceptor cells were noted after photic injury. The degeneration and decreasing number of rod bipolar cells were found after 3 days; the edema of horizontal cells occurred after 1 day but ameliorated gradually; decreasing number of amacrine cells was found after 1 day; sustained edema of ganglion cells and prolifeeration of the M?ller cells were found after photic injury. Pyknotic and edematous neruronal degenerations of inner retina were found in ultrastructural study. Conclusion The neurons in the inner retina as well as M?ller cells are involved in the degeneration after photic injury. Different neurons manifest different patterns of degeneration.

Abstract? AlM: To investigate the application effect of recombinant human epidermal growth factor derivative eye drops ( Jinyinshu) in treatment of dry eye.?METHODS:Sixty cases ( 87 eyes ) of dry eye patients were randomly divided into control group and observation group, 42 eyes and 45 eyes respectively. The control group received Chondroitin sulfate eye drops treatment, and the observation group were used for treatment of Jinyinshu. The changes of clinical efficacy, correlation index (symptom score, BUT, S l t, FL) before and after treatment, quality of life after treatment and the incidence of adverse reactions were compared.? RESULTS: ln the control group, the total clinical effective rate was 71%, which was significantly lower than that in the observation group ( 91%) , the difference was statistically significant ( P<0. 05 ); There were statistical differences of symptom scores, BUT, S▏t and FL level of the two groups before and after treatment (P<0. 05), and there were statistical differences of the above indexes after treatment between the two groups ( P<0. 05 ); The quality of life score was 142. 16 ± 10. 32 of the observation group after treatment, which was significantly higher than that in the control group after treatment (115. 24±7. 34), the difference was statistically significant (P<0. 05); The incidence of adverse reaction of the control group was 13%, 10% in the observation group, and there were no statistical differences (P>0. 05).?CONCLUSlON:Jinyinshu is significantly effective in the treatment of dry eye, and its clinical efficacy is better than chondroitin sulfate.

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.

Total glucosides of paeony (TGP)is used to treat rheumatoid arthritis(RA)as the first immunoregulatory drug in clinic.The efficacy of TGP in treating RA patients is definite, which is accompanied with mild adverse reaction and slow effects simultaneously.Paeoniflorin (Pae ),the main constituents of TGP,has a bioavailability of 3% ~4%,which may be served as the main reason for its slow effects.Therefore,in this paper,the pharmacokinetics of Pae as well as its influencing factors were re-viewed on basis of pulished papers.In addition,some problems about Pae were also discussed.

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.
