2 cases whose sepsis due to Whitmore bacterium with liver abscess were investigated in etiology, diagnoses (clinical, type of sepsis and microbiological diagnosis) and management. It was found that to reduce the mortality related to this rare medical condition, special high-dose antibiotics should be used early when Whitmore bacteria infection was suspected and the liver pus lesions (if exist) should be managed early. The disease should be considered in the patients with prolonged, fluctuated high fever, especially in high-risk subjects, and is should be repeated blood culture to find the bacteria.

Traumatic brain injury (TBI) is one of the leading causes of death and disability worldwide,particularly in young adults.Conventional imaging modalities such as CT or MRI can show most of the morphological changes of the brain in TBI.PET/CT and PET/MR can acquire both functional and morphological images compared with CT or MRI alone,which might be helpful for the diagnosis,management and prognosis evaluation of TBI.This review summarizes the applications of PET imaging in TBI patients.

Objective: To investigate the effects of miR-21 on the proliferation, invasion and migration of human hepatoma BEL-7402 cells and explore the possible mechanism. Methods: MiR-21 over-expression vector pGL3-miR21-EGFP (enhanced green fluorescent protein) was transfected into BEL-7402 cells. The expression level of miR-21 was detected by real-time fluorescence quantitative-PCR and the expression levels of phospho-AKT (p-AKT) and phospho-extracellular signal response kinase (p-ERK) were detected by Western blotting. The cell viability was examined by MTT assay. The cell migration and invasion abilities were evaluated by wound-healing assay and Transwell assay, respectively. The pGenesil-shAKT was transfected into BEL-7401 cells, and then the expression level of miR-21 was detected by real-time fluorescence quantitative-PCR, the expression levels of AKT and p-AKT were detected by Western blotting, the cell viability was examined by MTT assay, and the cell migration ability was evaluated by wound-healing assay. Results: As compared with the blank control (without transfection), the expression levels of miR-21 (P < 0.01), p-AKT and p-ERK (both P < 0.05) were up-regulated in BEL-7402 cells after transfection with pGL3-miR21-EGFP. As compared with the blank control, over-expression of miR-21 significantly promoted the proliferation, migration and invasion of BEL-7402 cells (all P < 0.05). After transfection with pGenesil-shAKT vector, the expression levels of AKT and p-AKT were down-regulated and the proliferation and migration abilities of BEL-7402 cells were inhibited (P < 0.05), but the expression level of miR-21 had no significant change. Conclusion: MiR-21 may contribute to the enhancement of proliferation and migration abilities of BEL-7402 cells through AKT/ERK signal pathway. Copyright © 2013 by TUMOR.

[Objective]To compare the purity and extraction rate of four purecollagen type I products prepared from various biomaterials by a limited enzyme digestion method for the use in tissue engineering.[Method]Bovine cortical bone, bovine achilles tendon, porcine achilles tendon and porcine skin were splitted into pieces of 0.2-0.5 mm. After being immersed in glacial acetic acid, they were extracted with pepsin. Then the crude products were dissolved, centrifuged, dialyzed and freeze drying to prepare pure collagen type I. The final products were confirmed by absorbance, amino acid analysis and'SDS-PAGE electrophoresis comparing them with the products of Sigma Company.[Result]The wave length of maximum absorbance of the final products was 230 nm, and the amino acid analysis and SDS-PAGE electrophoresis confirmed that the final products were collagen type I. The purity of product extracted from bovine cortical bone was the highest (96.12%) and higher than that from Sigma Company. The extraction rate of bovine achilles tendon collagen was the highest (75.34%).[Conclusion]Collagen type I of higher purity and higher extraction rate can be prepared using a limited enzyme digestion method.And the product from bovine cortical bone is better than the others,which has a promising prospect.

Objective To compare the effects of nasogastric tube and spiral nasointestinal tube on patients with severe brain injury. Methods Pa?tients receiving enteral nutrition with spiral nasointestinal tube or nasogastric tube were collected and investigated to evaluate the two schemes of en?teral nutrition from aspects of coma score,nutrition improvement,and catheter complications and so on. Results Detection of levels of total protein and prealbumin were conducted for all patients at 7 and 15 days after intubation. Each index was higher in the spiral nasointestinal tube group than in the nasogastric tube group. The reflux and aspiration rate was lower in the spiral nasointestinal tube group than in the nasogastric tube group. The dif?ferences were significant(P<0.05). Conclusion Using spiral nasointestinal tube to give enteral nutrition in patients with severe brain injury can improve the nutritional status,reduce complications,which is more contributory to the recovery.
