Objective To explore the clinical significance of Slug expression in papillary thyroid carci-noma(PTC). Methods Employed Ventana immunohistochemistry assay to determine the expression of Slug in 107 cases of PTC and para-tumorous normal tissue. The relationship with Slug expression in PTC and clinico-pathology data were also analyzed. Results Expression of Slug in PTC (65.4%, 70/107)and para-tumorous nor-mal tissue (14.0%,15/107)were statistically different (P < 0.001). Overexpression of Slug in PTC was signifi-cantly associated with capsular invasion and lymph node metastasis (P < 0.05). Conclusion Overexpression of Slug in PTC is associated with capsular invasion and lymph node metastasis , these may suggest some clinical significance of Slug expression in PTC in predicting lymph node metastasis and prognosis.

Objective To quantify the neurons in the temporal lobe white matter and find their distribution in the neurologically normal individuals.Methods The temporal lobe at the level of exterior geniculata body from brain autopsy samples of 14 neurologically normal individuals were made into large slice followed by quantitative analysis of neuron density,cell density,ratio and diameter of the neuronal nuclear and the distribution of white matter neurons using two-dimensional cell counting methods.Results With the depth of the white matter of the temporal lobe increasing,the neuron density decreased from 29.26 neurons/ mm~2 to 7.32 neurons/mm~2 and 0.00 neurons/mm~2,respectively;the cell density,neuron ratio and diameter of the neuronal nuclei all decreased.Conclusion There are neurons in the temporal lobe white matter of neurologically normal individuals,whose distribution of neurons is related to the depth of white matter.

OBJECTIVETo evaluate the biomechanical properties of tibial plateau depressed fracture fixed with a net-fixation of Kirschner wires.
METHODSTwenty homemade fracture models were fixed with eight 1.5 mm Kirschner wires in a net-fixation; 20 homemade fracture models were fixed with two 3.5 mm cortical screws. Plane-compressed and dot-compressed test were made on each 10 models of the two groups. The maximal force of anti-ompress and stiffness were measured and evaluated.
RESULTSIn plane-compressed test,mean maximal force of anti-compress and stiffness for screw fixation was (1,925.31 +/- 444.26) N and (2.28 +/- 0.53) N/mm2, respectively, for net-fixation was (1,609.62 +/- 277.72) N and (1.90 +/- 0.33) N/mm2, respectively. There was no statistical difference between the two fixation methods (P > 0.05). In dot-compressed test,mean maximal force of anti-compress and stiffness for screw fixation was (411.13 +/- 233.88) N and (2.66 +/- 1.52) N/mm2,respectively,for net-fixation was (1,105.58 +/- 290.66) N and (7.18 +/- 1.89) N/mm2,respectively,the net-fixation was better than that of the screw fixation (P< 0.01).
CONCLUSIONTreatment of tibial plateau depressed fracture with a net-fixation of Kirschner wires is a biological fixation and is a reliably method.

Objective To study the life quality of 2 - 3 years old survivors in Neonatal Intensive Care Unit (NICU). Methods Severe neonates were randomly assigned to intervention group (group 1,30 cases) and non- intervention group (group 2,30 cases) depending on the early intervention applied or not,as well as 30 healthy newborns as normal controls. The physical,neurological conditions and intelligence test were taken regularly. To investigate the psychological state, actions, temperament and family conditions when they were2-3 years old.Results Mental development index(MDI) and physical development index(PDI) in early interventional group were significant higher than those in group 2(P
