BACKGROUND:Traditional studies on foot and ankle biomechanics have limitation. Ankle joint was complicated and had big range of motion, so it is difficult to establish finite element models and to analyze the type of fracture.
OBJECTIVE: To construct the finite element models of distal tibial fractures and analyze the stability.
METHODS: CT data of ankle were colected from a normal male volunteer and the three-dimensional reconstruction of volunteer was made by Mimics software, and the effectiveness was verified. The ratio of different joint involvement and height of fracture block were assumed with Solidwork software, and finite element models of distal tibial fractures were established. Fracture stability was analyzed by ANSYS software using finite element method.
RESULTS AND CONCLUSION:The distal tibia fracture model was consistent with the relevant literature data, and finite element analysis could be further conducted. The ratio of articular surface involved was positively associated with fragment height and fracture displacement, and negatively associated with fracture stability. These results indicate that the three-dimensional finite element models of distal tibial fractures were successfuly established. Fracture stability was associated with the ratio of articular surface involved and fragment height.

The small-for-size syndrome (SFSS) is widely recognized as one of the most serious clinical complications. It substantially contributes to a poor prognosis after adult living donor liver transplantation. Currently, there is still no consensus on the exact definition and pathogenesis of SFSS. We reviewed the progress on research of pathogenesis of SFSS and put forward some relevant preventive and treatment measures, including donor selection, graft assessment, reduction of high portal vein perfusion, dual grafts technology, advanced molecular medicine and other innovative approaches. Also, we offered some relevant insights into the future research directions of SFSS.

Objective To observe the branches and distribution of the tibial nerve and analyze the compressed position of it.Methods Twenty sides of adult cadavers were anatomized and the tibial nerve branches in ankle,foot,the internal and external plantar tunnel were observed.Correlated data was measured and recorded.Results ① The tendinous part of abductor hallucis muscle that was located under the muscle and consisted the surface of the internal and external plantar tunnel was(8.62?0.79)cm in length,(3.01?0.30)cm in width,and the thickness of it was about(0.24?0.02)cm.The internal and external nerves were located in the internal and external tunnel.The length of the internal tunnel was about(4.58?0.41)cm,and the diameter was(1.11?0.10)cm.The length of the external tunnel was about(2.58?0.23)cm,the diameter was about(0.96?0.08)cm.② Internal hell nerve was in an isolated tunnel interior the hell,which was the hell tunnel.The length of the hell tunnel was about(3.03?0.21)cm,the diameter was(1.07?0.09)cm.Conclusion The tibial nerve branches can be compressed at internal,external plantar tunnel or the heel tunnel.When making neurolysis of the tibial nerve for tarsal tunnel syndrome patients,except for the flexor retinaculum,the internal and external plantar tunnel and the hell tunnel should also be decompressed especially for the patients with the symptom of compressed single branch.

Objective To investigate the effects of different acupuncture therapies on serum branched-chain amino acids (BAC and free tryptophan (F-Trp) in high-intensity military training soldiers. Methods Ninety healthy soldiers were randomly allocated to groups A, B and C, 30 soldiers each. Group A received treatment with electroacupuncture at Zusanli; group B, treatment by cupping on Zusanli;group C, no treatment. The three groups did a high-intensity 5 km running exercise after two weeks of treatment. Serum BACC and F-Trp contents were measured in the three groups before and at the end of treatment and at five days after treatment. Results It can be seen from table 2 that there were no statistically significant pre-treatment differences in serum BACC and F-Trp contents between the three groups of soldier subjects (P>0.05); there were statistically significant pre-/post-treatment differences in serum BACC and F-Trp contents in the three groups of soldier subjects (P＜0.05). There was a statistically significant post-treatment difference in serum BACC content between group A or B and group C (P＜0.05). There was a statistically significant difference in serum F-Trp content between group A or B and group C at the end of treatment and at five days after treatment (P＜0.05). Conclusion Acupuncture therapy can effectively improve bodily anti-fatigue ability and reduce high-intensity exercise induced muscular injury in military training soldiers.
