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.

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.

【Objective】To compare the fingerprint spectrum of amino acids(AA)of Lignum Santali Albi(LSA)from Indonesia,India and Australia.【Methods】Free AA and hydrolytic AA of LSA from Indonesia,India and Australia were analyzed by amino acid automatic analyzer.The detection wavelength was 570nm and 440nm.【Results】There were obvious differences among the free AA from three kinds of LSA.2S,4S-4-hydroxyproline(Hyp)was detected in Indonesian LSA in 11.77min(?=440nm)with the content of 1.431?7%,and became proline after hydrolysis.The peak of Hyp was not obvious or even undetectable in Indian LAS and Australian LSA.【Conclusion】There exist obvious differences among free AA from three kinds of LSA and 2S,4S-4-Hyp can be used as the specific compounds for the identification of LSA from Indonesia,India and Australia.

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.

Objective To analyse the experience and treatment of early phase severe acute pancreatitis (SAP) in intensive care units (ICU).Methods A multicenter retrospective study was done on patients with SAP treated in three major teaching hospitals (Beijing Hospital,Peking University First Hospital and Peking University Shenzhen Hospital) in China from Jan.2001 to Dec.2011.Results There were 188 patients who were enrolled in the study,including 121 males and 67 females.The age ranged from 19 to 104 (51.0±18.2) years.The mean APACHE Ⅱ score was (22.2±4.6).84.0％ of patients survived,the mortality was 10.1％ in the early phase and 5.9％ in the late phase.The most common systemic complications were acute renal injury (46.3 ％),acute respiratory distress syndrome (35.6％),and septic shock (17.6％).The local complication rate was 47.3％,which included acute peripancreatic fluid collections (32.8％),acute necrotic collection and walled-off necrosis (48.4 ％) and pseudocyst (18.8 ％).The conservative treatments included intensive care,fluid resuscitation,mechanical ventilation,continuous renal replacement therapy,antibiotics,glucose control,inhibition of pancreatic enzyme activity and secretion,and nutritional support.Surgical intervention included endoscopic retrospective cholangio-pancreatography and endoscopic sphincterectomy,B ultrasound or CT guided puncture and drainage,and surgical drainage and debridement of necrosis.Conclusions The early phase of SAP was characterized by systemic inflammatory response syndrome and multiple organ dysfunction syndrome which accounted for the first peak in mortality.Intensive care therapy and multi disciplinary comprehensive combined strategy were very important for these patients with systemic and local complications.ICU treatment in the early phase was preferred for patients with SAP.

AIM: To investigate the effect of c-Myc inhibitor 10058-F4 on human chronic myeloid leukemia ( CML) K562 cells and imatinib-resistant K562/G cells.METHODS: The protein expression of c-Myc was detected by Western blotting .Cell proliferation was evaluated by MTT assay and colony formation assay .PI staining was used to deter-mine the cell cycle distribution .Annexin V-PI staining was applied for apoptosis detection .RESULTS:Imatinib-resistant K562/G cells displayed lower sensitivity to imatinib than K 562 cells with high expression of c-Myc.Treatment with specific c-Myc inhibitor 10058-F4 inhibited the cell proliferation in a dose-and time-dependent manner , and K562/G displayed more sensitivity to 10058-F4 than K562 cells.10058-F4 also induced cell cycle arrest in G 0/G1 phase and induced apoptot-ic cell death in the 2 cells.Importantly, 10058-F4 suppressed the colony formation ability in K 562 and K562/G cells. CONCLUSION:c-Myc is a novel target to overcome imatinib-induced drug resistance , and c-Myc inhibitor provides a new approach in CML therapy .

Objective To investigate the clinical efficacy of atlantoaxial pedicle screw fixation plus bony fusion in treatment of traumatic upper cervical instability.Methods From October 2009 to August 2013,29 patients with traumatic upper cervical spine instability were treated with posterior atlantoaxial pedicle screws.The patients underwent autografting (n =19) and allografting (n =10) for spinal fusion.Surrcal outcomes were recorded including intraopcrativc blood loss,operation time,with or without nerve,blood vessel and spinal cord injury,wound healing and bone fusion rate.Results All operations were completed smoothly with operation time of 110 minutes (range,85-135 minutes) and blood loss of 150 ml (range,80-500 ml).At the follow-up of 10 months to 5 years (mean 18 months),bony fusion was detected for all the patients.Postoperative radiographs verified all patients were bony fusion with satisfactory cervical spine stability.No complications of reduction loss,fixation failure,and spinal cord or vertebral artery injury were observed except for 1 patient with low viruleut infection and 2 with delayed wound healing.Conclusion Single posterior atlantoaxial pedicle screw fixation provides security and reliable stability in treatment of upper cervical instability,however wound healing problems should be taken seriously.
