BACKGROUND:For severe thoracolumbar compression fracture (>1/3 compression), ideal therapeutic method is minimal y invasive internal fixation, which has good biomechanical functions. Moreover, bone graft is reliable. Injured vertebra reduction and bone graft stability achieved. Motor unit of spinal column and normal physiological function were retained, resulting in lessening nearby segmental degeneration.
OBJECTIVE:To discuss the design of single vertebrae internal fixation system and evaluate its biomechanical performance which apply to treat thoracolumbar compression fracture by endoscope.
METHODS:A brand-new single vertebrae internal fixation system was designed in accordance with data of anatomic measurement of adult thoracolumbar vertebra. Six fresh adult corpse specimens were prepared to produce models of L 1 compression fracture, and assigned to control group, fracture injury group, single vertebrae internal fixation system group, AF reduction internal fixation group and anterior plate internal fixation group.Three-dimensional movement range experiments were conducted separately.
RESULTS AND CONCLUSION:The biomechanical comparison showed that there was no significant difference in three-dimensional range of motion among single vertebrae internal fixation system group (anteflexion, left and right lateroflexion), AF reduction internal fixation group and anterior plate internal fixation group (P>0.05). However, range of motion significantly increased at backward extension, left and right rotation (P<0.05). Results suggested that the design of single vertebrae internal fixation system was novel and the system had good biomechanical performance at anteflexion, left and right lateroflexion. However, it needs to be improved in which lacks of stability of extension and rotation.

AIM To determine the contents of polymethoxylated flavones in Citri Reticulatae Pericarpium from eleven cultivar origins.METHODS HPLC was applied to screening extraction solvents (methanol,anhydrous ethanol,95％ ethanol,ethyl acetate and petroleum ether).Ultraviolet-visible spectrophotometry was adopted in the content determination of polymethoxylated flavones in eighteen batches of samples,nobiletin was taken as a reference substance,and the detection wavelength was set at 330 nm.RESULTS Ethyl acetate exhibited the best extraction effect,so it was selected as extraction solvent.Nobiletin showed a good linear relationship within the range of 3.024-13.104 μg/mL (R2 =0.999 8),whose average recovery was 101.37％ with the RSD of 1.34％.The contents of polymethoxylated flavones had obvious differences among samples from different cultivar origins,which were relatively high from Citrus reticulata ‘ Chachi’,Citrus reticulata ‘ Dahongpao’,Citrus reticulata ‘ Tangerina’,Citrus reticulata ‘ Ponkan’,Citrus reticulata ‘ Kinokuni’and Citrus reticulata ‘ Shiyueju’(more than 0.4％).CONCLUSION This simple and accurate method can effectively eliminate the interference of another flavonoids,which is suitable for the content determination of polymethoxylated flavones in Citri Reticulatae Pericarpium.

Objective To study the value of the technique of "Push-pull traction-relax homingrepeatedly confirmed" in the prevention of bile duct injury in LC. Methods From March 2001-August 2009, we applied this technique in 4800 cases of LC. The technique of "Push-pull traction" showed the structures of in the Calot's triangle. The technique of "relax homing" was to restore the cystic duct,hepatic duct and common bile duct to their original anatomical positions. The technique of "repeatedly confirmed" repeatedly identified the positions of the cystic duct, the common hepatic duct and the common bile duct. Results There was no bile duct injury. Conversion to open surgery happened in 118patients due to difficulties in identifying the Calot's triangle structures, bile duct stones, gallbladder cancer, and gallbladder-duodenal fistula. Conclusions The "Push-pull traction-relax homing-repeatedly confirmed" technique could effectively prevent bile duct injury in LC. The method is simple, easy to master and worthy of promotion.

The bionic optic nerve can mimic human visual physiology and is a future treatment for visual disorders. Photosynaptic devices could respond to light stimuli and mimic normal optic nerve function. By modifying (Poly(3,4-ethylenedioxythio-phene):poly (styrenesulfonate)) active layers with all-inorganic perovskite quantum dots, with an aqueous solution as the dielectric layer in this paper, we developed a photosynaptic device based on an organic electrochemical transistor (OECT). The optical switching response time of OECT was 3.7 s. To improve the optical response of the device, a 365 nm, 300 mW·cm ^-2 UV light source was used. Basic synaptic behaviors such as postsynaptic currents (0.225 mA) at a light pulse duration of 4 s and double pulse facilitation at a light pulse duration of 1 s and pulse interval of 1 s were simulated. By changing the way light stimulates, for example, by adjusting the intensity of the light pulses from 180 to 540 mW·cm ^-2, the duration from 1 to 20 s, and the number of light pulses from 1 to 20, the postsynaptic currents were increased by 0.350 mA, 0.420 mA, and 0.466 mA, respectively. As such, we realized the effective shift from short-term synaptic plasticity (100 s recovery of initial value) to long-term synaptic plasticity (84.3% of 250 s decay maximum). This optical synapse has a high potential for simulating the human optic nerve.
