A novel mono-hierarchical muti-axiel classification coding scheme for medical image retrieval is proposed.The so-called MOAB coding scheme consists of four axes with three to four positions ranging from0to9,from A to Z.In particular,the modality code M describes imaging modality and relevant technical detail,and the orientation code O models examined body orientation.The anatomy code A refers to the body region examined and the biology code B describes the biological system examined.The MOAB classification-coding scheme enables a unique classifi-cation of medical images so that medical image retrieval can be efficient.The code is flexible and easy to be ex-tended.

OBJECTIVETo study clinical effects of inversive LISS (less invasive stabilization system, LISS) plate combined with steel wire for the treatment of Seinsheimer type V subtrochanteric femoral fractures.

METHODSFrom January 2009 to Janurary 2012, 11 patients with Seinsheimer type V subtrochanteric femoral fractures were treated with inversive LISS plate combined with steel wire, including 8 males and 3 females, ranging in age from 35 to 61 years old (averaged, 51 years old). Causes of injury: 8 patients caused by accident and 3 patients caused by falling down. According to X-ray examination, all the patients were type V subtrochanteric femoral fractures and were treated with LISS plate combined with steel wire. Merle d'Aubigne scores were used to evaluate therapeutic effects on hip.

RESULTSThe mean period of follow-up was 16 months (ranged, 12 to 28 months). All the patients obtained bone union for average 3.8 months (ranged from 3 to 4.3 months). There were no complications such as deep infection,deep vein thrombosis, pulmonary embolism and bone nonunion. According to Merle d'Aubigne scores, 7 patients got an excellent result and 4 good.

CONCLUSIONInversive LISS plate combined with steel wire for the treatment of Seinsheimer type V subtrochanteric femoral fractures is satisfactory, Which can provide stable fixation for fracture end and provide an ideal internal fixation method for treatment of this kind of fractures in the future.

Objective To investigate the application of noninvasive correction of congenital auricle defor-mity,and to analyze the cure rate and the causes of incidence of complications. Methods From January 2015 to December 2016,33 patients with unilateral or bilateral congenital auricle deformities were treated with non-surgi-cal correction technique in the Plastic Surgery Department of Guangzhou General Hospital. When the treatment was completed,the VAS score was used to assess the satisfaction of the patient's parents. Results From January 2015 to December 2016,33 patients(53 ears)received noninvasive treatment of the ear deformity correction system. The average age of the patients was(63.5 ± 41.3)days,the average treatment time was(41.6 ± 15.4)days,and the average parental satisfaction was 3.76 ± 0.93(total score:5 points). Significant difference was observedin auri-cle morphology data between pre- and post- treatment ,except for cranioauricular angle(P < 0.05). Conclusions In this study,the cure rate for non-surgical correction was good,however,the satisfaction of treatment decreased with age.The most common complication of treatment was auricle skin damage. The reasons of causing complica-tions maybe the age-induced reduction of ear cartilage elasticity which brought great pressure on the ear ,and the increase of the treatment time.

Objective To investigate the diagnostic values of color ultrasound to the stenosis of extracranial carotid arteries.Methods Color ultrasound examination and digital subtraction angiography(DSA)were performed in 145 patients with ischemic cerebravascular disease.The sensitivity and specificity of color ultrasound for the stenosis of extracranial carotid arteries were analyzed according to the golden standard of DSA results.Results The sensitivity and specificity of color ultrasound for stenosis of carotid bifurcation,subclavicular artery and vertebral artery were 96.8%,80.6%,60.0% and 98.7%,33.3%,89.0%.The accuracy of color ultrasound for stenosis of carotid bifurcation,subclavicular artery and vertebral artery were 93.0%,92.8% and 82.1%.Conclusion Color ultrasound examination are effective for the diagnosis of carotid bifurcation sterosis,and less effective for the diagnosis of the subclavicular and vertebral artery stenosis because of the poor sensitivity.

Objective To investigate the effect of intratracheal instillation of curosurf on neonatal respiratory distress syndrome ( NRDS ) in children with right ventricular function.Methods 52 patients with NRDS were retrospectively selected and divided into two groups according to different treatment.The patients in the conventional group were treated with nasal airway ventilation.Based on the conventional group, the curosurf group was taken with curosurf.26 cases were in each group.The blood gas index (PaCO2, PaO2, pH), inflammatory reaction (TNF-α, IL-10), SF of the two groups were compared, the complications and curative effect of the two groups before and after treatment were taken for statistics.Results There was no significant difference in pH value between the two groups at each time point.The PaO2 expression levels in the curosurf group at different time points after treatment were significantly lower than the conventional group (P<0.05).The levels of TNF-αand IL-10 in the curosurf group were more stable than those in the control group at different time points after treatment (P<0.05), and the degree of SF increasing at different time points were higher (P<0.05).The total effective rate 80.77% of the curosurf group was significantly higher than that of the conventional group 61.54%(P<0.05).The total complication rate 19.24% had no significant differences with the conventional group 23.08%.Conclusion Intratracheal instillation of CsA in the treatment of NRDS has the advantages of simple operation, little side effect, rapid recovery of blood gas index and inflammatory factors, so it is a feasible method for clinical treatment of NRDS.

The carboxyl-terminal amino acids 272-299-truncated apoE4 (delta272-299) is the main fragments of apoE4 hydrolysate in neurons. The effects of truncated-ApoE4 (delta272-299) overexpression on tau phosphorylation in cultured N2a cells were investigated. The truncated-apoE4 (delta272-299) cDNA was subcloned into pEGFP-c3 to form recombinant pEGFP-T-apoE4. pEGFP-c3, pEGFP-T-apoE4 and pEGFP-apoE4 were transfected into N2a cells respectively by lipofectamine 2000 method. After 24--48 h, tau phosphorylation was detected by Western blot assay and glycogen synthase kinase-3 (GSK-3) activity by using GSK-3 activity assay. The results showed that the overexpression of both full length-apoE4 and truncated apoE4 fragments in N2a cells induced a dramatic increase in phosphorylation of tau at Ser202 sites and the activation of GSK-3 as compared with untransfected cells, most significantly in the cells transfected with pEGFP-T-apoE4 (P < 0.05). It was concluded that in vitro overexpression of truncated-ApoE4 (delta272-299) can result in tau hyperphosphorylation in N2a cells by activating GSK-3, suggesting truncated-ApoE4 (delta272-299) might contribute the pathogenesis of Alzheimer disease.
