Objective To evaluate the actual displacement of a femoral neck fracture following close reduction under the C-arm X-ray perspective.Methods From June, 2006 to June, 2009, we managed 12 patients with femoral neck fracture by open reduction and internal fixation.They were 8 males and 4 females, aged from 23 to 65 (average, 42.3) years old.We tried close reduction of their fractures under the C-arm X-ray perspective before a temporary fixation.Next we performed open reduction, readjusted the fracture ends, and placed internal fixation.The actual displacement of the fracture measured after open reduction was carefully compared with the close reduction under the X-ray perspective.Results A substantial displacement was found after open reduction in 7 patients who had achieved anatomic reduction under the X-ray perspective.In the other 5 patients who presented with a slight displacement after close reduction under X-ray perspective, the actual displacements were larger than the X-ray observations but completely reduced after open reduction.The actual measurements after open reduction were significantly larger (3.21 ± 0.96 mm on average) in the anteroposterior displacement ( t = 11.540, P = 0.000), but insignificantly larger (0.58 ±0.93 mm on average) in the superior-inferior displacement ( t = 2.184, P = 0.346) than those after close reduction.Conclusions In general, anatomic reduction can not be achieved for a femoral neck fracture under the C-arm X-ray perspective.Consequently, open reduction may be better than close reduction in the treatment of femoral neck fracture in that improper reduction can block blood supply to the femoral neck and dissection of the capsula articularis coxae can improve blood supply as well as help decompression.

In recent years,research on autoimmune pancreatitis (AIP) has gained significant progress.AIP is a special type of chronic pancreatitis which is mediated by an autoimmune mechanism.It is characterized by the infiltration of lymphocytes and plasma cells leading to pancreatic fibrosis and dysfunction.AIP can affect the bile ducts,salivary glands,kidneys and other organs outside the pancreas.The common manifestations include obstructive jaundice,abdominal pain,and weight loss,which are similar to pancreatic cancer.Steroid therapy is of significant effect.There is no consensus nowadays on the diagnostic criteria of AIP across the world.There are many studies on the pathological subtypes,imaging,serological markers and biopsy techniques on AIP,and research focuses on the differential diagnosis from pancreatic cancer.

Objective To study the value and limitation of CT in the damage to multiple organs in children with Langerhans cell histiocytosis (LCH). Methods Analysis of CT manifestations was performed in 13 cases of LCH proved by clinical features, laboratory data, and pathologic changes. Localized LCH was found in 4 cases, and disseminated LCH in 9 cases. All cases were examined by plain scan in craniocerebral, chest, liver, and spleen, and four cases by contrast-enhanced CT scan. Results The male outnumbered female in this group. Cranial bones were involved in the sequence of temporal bone(8 cases), parietal bone (3 cases), occipital bone (2 cases), and frontal bone (1 case). CT findings were very sensitive in showing the early destructions of the bones. The characteristic manifestation on CT was multiple lytic lesions of the flat bones at any sites, without reactive sclerosis and soft tissue mass accompanied with the bony lesion. Imaging findings presented later than the clinical manifestations for LCH involving the hypothalamus/pituitary axis. Involvement of the lung at various stages by LCH could be demonstrated by CT scan. Conclusion Imaging manifestations had no characteristics in LCH involvement. The sites of predilection and related CT manifestations could be suggestive of the diagnosis. In addition, CT findings can be helpful in the classification and evaluation of the therapy and prognosis in LCH.

objective: To study the effects of BMP on the growth of osteosarcoma cells. Methods: Human antisense BMP2 retrovirus expression vector was constructed and transfected into human osteosarcoma OS 9901 cells by Lipofect AMINE. Positive cell clones were selected with G 418. The expression of BMP and PCNA were determined by immunohistochemical methods, image analysis and expressed as grey level. The morphology and cell cycle distribution of the cells were studied by electronmicroscope and flowcytometry respectively. Results:The grey levels of BMP and PCNA in the transfected cells were 198.4?8.51 and 197.3?3.22, those of the control were 135.1?12.32 and 142.9?8.47,respectively. G 1, G 2 and S phase cells were 51.9%,18.2% and 22.7% in the cell cycle of transfected cells, while those of the control were 52.8%,11.1% and 36.1%, respectively.Increased lysosome and small pieces of chromatin were observed in the transfected cells under electronmicroscope. Conclusion:Transfection of antisense BMP2 may inhibite the expression of BMP and proliferating activity of osteosarcoma cells.
