Objective To analyse the economies of scale in public hospitals in Zhejiang Province. Methods One hundred and twenty-five public hospitals in Zhejiang Province with qualification no less than class two level two were selected as sample hospitals. Douglas production function was employed to analyse the relationship between investment and output in sample hospitals between 2004 to 2006, with two types of production models established by medical service and incomes in hospitals as dependent variables. Results From 2004 to 2006, the medical service and incomes of sample hospitals were in line with economies of scale. The production increase rate was higher than investment increase rate. The medical service, incomes, total assets and number of staff in class three hospitals were higher than those in class two hospitals (P =0.000). Conclusion Economies of scale is the ultimate incentive to continuous outstretch for hospitals. Hospitals should rationally control the scale so as to avoid problems in medical service caused by overstretch.

[Objective]To compare the expression of calcitonin gene-related peptide(CGRP) receptor in rat bone marrow mesenchymal stem cells(rBMSCs) and the induced osteoblasts.[Method]The rBMSCs were isolated using whole bone marrow adherence method,and classified into osteoblast-induced group and non-induced group.In the different periods of culturing(1,2,and 3 weeks),identification of osteoblasts was performed by immunohistochemistry and reverse transcriptase-polymerase chain reaction(RT-PCR),and expression of the CGRP receptor was detected by Western Blot and RT-PCR.[Result]RT-PCR test demonstrated that osteoblast-induced group had a higher expression of CGRP receptor than non-induced group at the same time point,expression of CGRP receptor was increased in a time-dependent manner in the osteoblast-induced groups.Western Blot test demonstrated that osteoblast-induced group had a higher expression of CGRP receptor than non-induced group at the same time point.Expression of CGRP receptor was increased in a time-dependent manner in osteoblast-induced groups.[Conclusion]According to the mRNA test and protein test,it is suggested that CGRP receptor exists in the rBMSCs.CGRP receptor expression increased in the progress of osteogenic differentiation.
