Objective To study prognosis and grading of somatosensory evoked potential(SEP)in long-term unconscious patients after severe traumatic brain injury(TBI).Methods Five prognostic factors including age,sex,injury mechanism,history of temporal craniotomy and SEP grading were selected and analyzed in 47 patients after severe TBI with a duration of unconsciousness longer than two weeks.The prognosis was judged by Glasgow Outcome Scale.Results Prognosis was closely associated with SEP grading(P=0.024).The accuracy of SEP in assessing the prognosis was 91.5%.About 95%-100% of patients with SEP at grade Ⅲ-Ⅲ ended up with severe disability,persistent vegetative state or death.However,43.75% of patients with SEP at grade Ⅰ had good prognoses.Conclusions The SEP grading can objectively and accurately evaluate patients' prognosis and demonstrate the brain function.

Objective To explore the moves that creating magnetic work environment in hospital, in order to improve the nurses job satisfaction and reduce the turnover rate then stable the nursing team. Methods Through a series of measures such as the establishment of scientific rational allocation of human resources, implementing fair performance evaluation and allocation mechanism, carrying out the nurse grading management system to create magnetic nursing work environment, the nurse job satisfaction and turnover rate were compared before and after the measures. Results In January 2014 a total of 520 questionnaireswere issued, 519 valid questionnaires, and the effective recovery rate was 99.81%(519/520);And 559 were valid of 577 issued questionnaires, which was 96.88% (559/577). The overall score of nurses′job satisfaction increased from (3.20±0.46) points in 2013 to (3.41±0.52) points in 2014 (t=9.40, P= 0.000); The nurse turnover rate fell to 1.97%(13/661) from 5.13% (30/585) (χ2= 10.27, P= 0.003). Conclusions That is very important for remain stable and high quality nursing team to carry out scientific and fine management according to the demand of nurses, so as to create a safe, harmonious, positive, cooperative magnetic nursing work environment which have development direction and space.

Metastasis contributes to the poor prognosis of hepatocellular carcinoma (HCC). However, the mechanism through which a primary HCC cell develops into a metastatic phenotype is not well understood. The purpose of this study was to examine the correlation between metadherin (MTDH)/astrocyte elevated gene-1 (AEG-1) expression in HCC cell lines of different metastatic potentials and such metastatic phenotypes as orientation chemotaxis and adhesion. MTDH/AEG-1 expression was detected by RT-PCR and western blotting in HCC cell lines (HepG2, Huh7, Sk-HEP-1, MHCC-97H). Distribution of MTDH/AEG-1 was observed by immunofluorescence staining and confocal laser scanning microscopy. The abilities of orientation chemotaxis and adhesion and the index of interaction between HCC cell lines and microvascular endothelial cell lines (MVECs, including HUVECs and HPMECs) were measured by chemotaxis assay and adhesion assay, respectively. The results showed that MTDH/AEG-1 protein expression was significantly higher in high metastatic potential cancer cell lines (Sk-HEP-1, MHCC-97H) than in low metastatic potential cell lines (HepG2, Huh7) (P<0.05). The MTDH/AEG-1 protein was localized in the perinuclear region of HCC cells. Furthermore, the abilities of orientation chemotaxis and adhesion of HCC cells to HPMECs were increased as compared with those of HCC cells to HUVECs (P<0.05). The abilities of orientation chemotaxis and adhesion were much stronger in Sk-HEP-1 and MHCC-97H cells with MTDH/AEG-1 highly expressed than in HepG2 and Huh7 cells with MTDH/AEG-1 lowly expressed (P<0.05). These results suggested that the expression of MTDH/AEG-1 gene in HCC cell lines of different metastatic potentials was closely positively related to the abilities of orientation chemotaxis and adhesion of HCC cells. It was deduced that MTDH/AEG-1 might play a pivotal role in the lung-specific metastasis of HCC, which may be mediated through orientation chemotaxis and adhesion abilities of HCC cells. MTDH/AEG-1 may serve as a potential therapeutic target for HCC.

The incidence of brain metastases in patients with non-small cell lung cancer (NSCLC) has increased as a result of improved local control rate and survival rate. Prophylactic cranial irradiation (PCI) has been proven to reduce the incidence of brain metastases and improve survival rate in patients with NSCLC. However, the value of PCI for NSCLC is still controversial. This paper reviews the progress of the efficacy and adverse reactions after PCI treatment for patients with NSCLC.

The clinical data of 2 children with early graft liver dysfunction (EAD) admitted to the Pediatric Intensive Care Unit, Shanghai Children′s Medical Center, Shanghai Jiaotong University School of Medicine were retrospectively analyzed to discussed the therapeutic significance of non-biological artificial liver technology, such as intermittent plasma exchange (PE) combined with continuous veno-venous hemodiafiltration (CVVHDF) in children with EAD.Case 1 was suffering from biliary atresia, and case 2 was suffering from Niemann-Pick disease.Graft liver dysfunction and multiple organ dysfunction occurred in 2 children after liver transplantation.PE and CVVHDF were initiated early in the first two days after liver transplantation.After one-week therapy with intermittent PE plus CVVHDF, acute multiple organ dysfunction were reversed with liver function remarkably improved in the 2 cases.Therefore non-biological artificial liver technique can be tried after liver transplantation in children.This technique contributes to the recovery of liver function and can improve the secondary multi-organ insufficiency.
