Objective To determine whether the poking reduction and bone grafting technique with guide through bony tunnel can correct a Hill-Sachs lesion. Methods A total of 30 cadaveric humeri were equally divided into three groups, 10 cadaveric humeri per group. Hill-Sachs lesions were replicated with a osseous defect involving 10% (group A ) , 20% (group B ) and 30% (group C ) of the articular surface. All the bone defects in each group were measured and the poking reduction and bone grafting technique with guide through a bony tunnel was performed in group B and group C. The preoperative and postoperative transverse arc length, longitudinal are length, depth and volume of the osseous defects in group B and group C were compared by using paired t test. Results Before reduction, the transverse arc length of the bone defects was ( 10.9 ± 1.4 )mm in group B and ( 16.3 ± 2.3 ) mm in group C ; longitudinal arc length was ( 22.4 ± 2.4 ) mm in group B and ( 28.0 ± 2.2 ) mm in group C ;depth was (6.9±0.9) mm in group B and (11. 1 ±0.9) mm in group C; volume was (708.7±93.9) mm3 in group B and (1338.3 ± 185.6) mm3 in group C. After reduction, the transverse arc length of the bone defects was (5.1 ± 2.4 ) mm in group B and ( 7.6 ± 3.6 ) mm in group C ; longitudinal arc lengthwas (10.5 ±4.9) mm in group B and (12.3 ±5.3) mm in group C; depth was (0.3±0.1 ) mm in group B and (0.4 ±0.1 ) mm in group C; volume was (48.9 ± 16.1 )mm3 in group B and (70.3 ± 37.9) mm3 in group C. The comparison of all the parameters showed statistical difference (P <0. 01 ). Conclusion The poking reduction and bone grafting technique with guide through a bony tunnel can effectively correct the Hill-Sachs lesions with humeral head osseous defects involving 20% -30% of the articular surface.

OBJECTIVETo analyze the complications of percutaneous kyphoplasty except bone leakge for the treatment of osteoporotic thoracolumbar vertebral compression fractures.

METHODSFrom October 2008 to October 2012,178 patients with 224 osteoporotic vertebral compression fractures were treated with percutaneous kyphoplasty under local anethsia. There were 72 males and 106 females,ranging in age from 58 to 92 years old,with an average of 75.3 years,including 93 thoracic vertebrae and 131 lumbar vertebrae. The complications except bone cement leakage were analyzed during operation and after operation.

RESULTSAll operations were successful and all patients were followed up from 12 to 60 months with an average of 26.2 months. No death was found. Bone cement leakage occurred in 27 cases, about 15.1% in 178 cases; and complications except bone cement leakage occurred in 15 cases. There was 1 case with cardiac arrest,was completely recovery by cardiopulmonary resuscitation (CPR) immediately; and 1 case with temporary absence of breathing,was recovery after treatment. There were 3 cases with fall of blood pressure and slower of heart rate; 1 case with intestinal obstruction; 2 cases with local hematoma and 1 case with intercostal neuralgia. Vertebral body fractures of 2 cases were split by bone cement and the fractures of adjacent body occurred in 4 cases.

CONCLUSIONIt's uncommon complication except bone cement leakge in treatment of osteoporotic thoracolumbar vertebral compression fractures with percutaneous kyphoplasty. The complication of cardiopulmonary system is a high risk in surgery; and cytotoxicity of bone cement,nervous reflex,fat embolism and alteration of intravertebral pressure may be main reasons.

Objective To explore the effect of edaravone (ED) on the neurological functionaldeficits, apoptosis and expression of caspase-3 protein following focal cerebral ischemia/reperfusion(I/R)injury in rats. Methods A total of 24 male Sprague-Dawley (SD) rats were randomly allocated intothe sham-operation group, cerebral I/R group, normal saline treatment group and ED treatment group, 6rats in each group. Rat models with focal cerebral I/R injury induced by middle cerebral artery occlusion(MCAO) were established using a modified suture method. ED (3mg/kg) or equal volume of normalsaline was injected intraperitoneally immediately after cerebral ischemia and 12 h after reperfusion in thetreatment groups;the rats in sham-operation group underwent the same modeling procedure withoutischemia by nylon suture. The neurological behavioral deficits were evaluated 24 h after I/R injury;,immunohistochemical staining and Western blot assay were applied to detect the change in the expressionof caspase-3 protein; in situ TdT-mediated dUTP-biotin nick end labeling (TUNEL) assay was used tostudy the change in neuronal apoptosis. Results The scores of neurological behavioral deficit scale,the positive cells and expression of caspase-3 protein, and the apoptotic cells in the ED treatment groupwere significantly decreased, compared with that of the I/R group and normal saline treatment group(P<0.05 for each comparison). Conclusion ED may effectively reduce neuronal apuptosis andneurological functional deficits after cerebral I/R injury, which might be related with the inhibition of thecaspase-3 protein expression.

OBJECTIVETo evaluate the effects of school entrance age on cognition and behaviors in children with attention deficit hyperactivity disorder (ADHD) using mathematical event-related potential (ERP), behavioral test, and Conners Parent Symptom Questionnaire (PSQ).

METHODSFifty-eight ADHD children aged 7-12 years were enrolled and classified into older age and younger age groups according to the school entrance age (n=29 each). The children in the older age group were admitted at an age of 6 years and 6 months to 6 years and 11 months, and those in the younger age group were admitted at an age of 6 years to 6 years and 5 months. The ERP with a mathematical task was used to detect the difference in brain electrical activity between the two groups, and the behavioral test results were compared. The children's parents were asked to complete the PSQ, and the scores on each subscale were compared.

RESULTSThe ERP detection showed that the older age group had a significantly higher P2 amplitude for wrong answers than the younger age group (10.9±5.0 μv vs 8.5±3.6 μv; P<0.05). The younger age group had a significantly shorter time of response to wrong answers than the older age group (619±340 ms vs 870±418 ms; P<0.05). The scores on the subscales of learning problems and impulse-hyperactivity of PSQ were significantly higher in the younger age group than in the older age group (P<0.05).

CONCLUSIONSSchool entrance age can affect cognition and behaviors in children with ADHD, and the ADHD children with a younger school entrance age have an obvious defect in executive function, especially the function of error detection, which leads to the prominent problems in impulse-hyperactivity and learning.

OBJECTIVETo understand the effects of the IL-1, TNF-alpha cytokines on the pathogenesis of periapical lesions by investigating its gene expression in rat.

METHODSThe model was established by surgically exposing mandibular molar teeth and left open to permit infection from the oral environment. The SD rats were killed at 1, 2, 3, 4 weeks and mandibular molar teeth X-ray were taken. In situ hybridization was used to test IL-1alpha, IL-1beta, TNF-alpha mRNA expression in periapical area and the kinds of positive cells were identified. Using image analysis system analyzed gene expression semi-quantified.

RESULTSIL-1alpha, IL-1beta and TNF-alpha mRNA were all expressed beginning at 1 week, peaked at 3 weeks, and declined somewhat at 4 weeks, but IL-1beta mRNA was expressed at much lower levels with the same kinetics (P<0.01). Most of the staining occurred in areas that had heavy inflammatory infiltrate, fibroblasts, or endothelial cells. There was a statistically significant correlations between the area of periapical lesion and the number of positively stained cells for IL-1alpha and for TNF-alpha (IL-1alpha: r=0.875, P<0.001; TNF-alpha: r=0.858, P<0.001), and between the number of positive cells for IL-1alpha and that of for TNF-alpha (r=0.969, P<0.001).

CONCLUSIONSIL-1alpha and TNF-alpha genes are highly expressed in developing periapical lesions in rat, which supports the hypothesis that these two cytokines play a key role in pulpal and periapical pathogenesis, including the concomitant bone destruction.
