Objective To investigate the predictive value of mnodified early warning score (MEWS) in predicting emergency potential in critically ill patients and its feasibility.Methods A total of 298 patients in the emergency department and emergency room were evaluated using the MEWS.The distribution of transfer to cadiopulmanary resuscitation (CPR),intensive care unit (ICU) and high dependency unit (HDU),length of hospital stay ( more than 1 month or not) and transferred to advanced hospital,death were recorded,and all patients were followed up.Results Patients with different MEWS were treated significantly differently ( x2=258.697,P < 0.001 ),and their prognosis were also significantly different ( x2=115.938,P < 0.001 ).the condition of patiens were significantly correlated with MEWS ( r=0.848,P < 0.001 ).Conclusion The MEWS in the prediction of potential in critically ill patients in emergency department is feasible as a special emergency assessment system and is recommended for promotion.

OBJECTIVE:
To investigate the effect of T lymphoma invasion and metastasis 1 (Tiam 1) overexpression in head and neck squamous cell carcinoma (HNSCC) cells.
METHOD:
Endogenous expression of Tiam 1 in 8 head and neck squamous cell carcinoma cell (HNSCC) lines was investigated by real-time RT-PCR. A lentivirus vector containing Tiaml was transfected into UM-SCC-47 cells, a head and neck squamous cell carcinoma cell line with little endogenous Tiaml expression. Stable clone, obtained by G418 screening, were assayed by RT-PCR and Western blot to validate the gene expression efficiency. The biological behaviors of the transduced cells were determined by cell counting, MTT and in-vitro migration assay.
RESULT:
Tiam 1 gene was highly expressed in M2 cell line and it's low level expression was found in UM-SCC-47. Cell counting and MTT assay showed that over-expression of Tiaml significantly promoted cell proliferation (P < 0.05). The cell monolayers overexpressed Tiaml that resulted in a significant increasment of cell migration in infected head and neck squamous cell carcinoma cell lines (P < 0.05).
CONCLUSION
Tiam 1 gene plays an important role in the growth and migration in head and neck squamous cell carcinoma cell lines. It may be a useful marker for metastasis of head and neck squamous cell carcinoma.
