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 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.

Object To study the difference of phenylethanoid glycoside between the cultured cells of Cistanche salsa (C. A. Mey.) Benth. et Hook. f. and Herba Cistanche. Methods Making comparison by means of FTIR and HPLC technique. Results Using the FTIR technique, the infrared spectrum of cutured cell of C. salsa was similar to that of native Herba Cistanche at a certain extent. The HPLC analysis indicated that the main chemical constituents in cultured cells of C. salsa were similar to that of native Herba Cistanche while considerable difference of constituents was found between them. Conclusion On the whole, there are much more constituents in the cultured cells of C. salsa comparing with the native Herba Cistanche. The content of echinacoside and acteoside in the cultured cells is much higher than that in the native Herba Cistanche.

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.

BACKGROUND: A discussion is ongoing whether the elderly patients with femoral neck fractures should be treated with a non-cemented or a cemented hemiarthroplasty.OBJECTIVE: To evaluated the results of cemented hemiarthroplasty for femoral neck fractures in the patients older than 85 years with high-risk clinical problems and functional outcomes.METHODS: Thirty-two patients with femoral neck fractures were treated with cemented bipolar hemiarthroplasty. X-ray examination after operation was done at 1, 3 and 6 months and annually in all patients. The mean follow-up period was 2 to 5 years.RESULTS AND CONCLUSION: Medical complications occurred in five patients (16%) and four patients (25%) died within the follow-up period. Dislocation occurred in one patient (3%). None of the patients had heterotopic ossification. The mean Harris-hip score was 84. Cemented hemiarthroplasty can provide stability, security and good outcomes for the treatment of femoral neck fractures in elderly patients.

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.
