The balanced scorecard, a new performance management tool used by enterprises, transcends the traditional assessment method of measuring an enterprise only from the financial perspective and renders it possible to view an enterprise simultaneously from four perspectives: financial, customer, internal process, and learning and growth. The balanced scorecard, which can also be used in the medical and health field, enables the hospital to continuously improve performance so as to realize its vision and strategic goals. The paper gives an account of the concept, development steps and principles of the balanced scorecard and its application in hospital strategic management, thus identifying a new channel for hospital development.

AIM and METHODS: In situ hybridization and image-analysis system were used to investigate the expression of NOSⅢ mRNA in cultured porcine pulmonary artery endothelial cells (PAEC) under normoxic or chronic hypoxic conditions. RESULTS: The expression of NOSⅢ mRNA were increased by 48%, 125%, 119% respectively in the 2nd, 4th, 6th subculture of normoxic PAEC after expouse to acute hypoxia for 12 hours while in chronic hypoxic group,the expression of Ⅲ NOS mRNA were increased by 92%, 245%, 565% separately. The increase was more apparent in chronic hypoxic group than in normoxic group and became more significant following the prolonging duration of hypoxia. CONCLUSION: Chronic hypoxia increased the expression of NOSⅢ gene in PAEC in response to acute hypoxia. Nitric oxide may play an important role in the decrease of hypoxic pulmonary vasoconstriction caused by chronic hypoxia.

Objective To compare the treatment effects and side events between chemoradiotherapy and radiotherapy alone for patients with primary cervical cancer.Methods Totally 197 patients with primary cervical cancer in our hospital from 2000 to 2006 were studied.They were divided into two groups: radiotherapy alone(RT)or cisplatin-based chemoradiotherapy(CRT).Group of RT included 100 patients who received external irradiation by ~(60)Co and intracavitary irradiation by ~(192)Ir.Group of CRT included 97 patients who received cisplatin-based chemoradiotherapy.The RT regimen was the same as group RT.Results The local control(CR+PR)in two groups had no statistic difference(P=0.500).The total 5 year survival rate in the two groups were 82% and 79%,with no significant difference(P=0.177);however,there was a significant difference for stage Ⅲ squamous cell carcinoma of the cervix,the 5 year survival rate being 56% and 84%,respectively(P
