Chinese Journal of Hospital Administration 2012;28(2):153-157
As introduced in the paper,Australian government subsidize the public hospitals with all their budget needs as compensation,with the two levels of governments constituting the largest buyer of health products and services in the country.In addition,the government supports the hospitals with their facilities.A rational government investment mechanism is proposed with reference to such a model for the ongoing reform of public hospitals in China.

Objective To unmask clues for the investigation of PIH pathogenesis by detecting the altered gene expression profile of placentas from PIH patients. Methods Clinical data and placentas were collected from 42 PIH patients and 22 normotensive pregnancies in seclective cesarean section to construct PIH database from Mar. 2001 to Sep. 2002 in Xi’an district. Suppression subtractive hybridization (SSH) was performed to set the subtractive cDNA library and differential screening was used to identify the positive clones;insertion of positive clones were sequenced by T7 primer method. RT-PCR and immunohistochemistry were employed to confirm the putative gene inhibin A expression. Results A database was set up that consists of pre- and postpartum clinical data and placenta samples of 42 preeclamptic pregnancies and 22 normotensive ones From which,150 features of placental tissue microarray were made. One hundred and three positive clones were isolated by SSH and differential screening. Sequencing and BLAST analysis showed that 90 insertion shared more than 95% homology with sequences in the GenBank/EMBL database. We identified 36 putative genes including pregnancy-specific glycoproteins gene (BC005924),serine protease inhibitor gene (BC012868),VEGFR-1 gene (AF063657),cytokeratine 7 gene(CK7) (AF509887),etc. Inhibin beta A gene was highly expressed in placentas in PIH patients. Conclusion The gene expression profile in PIH placenta was greatly changed;it might be necessary to investigate the role of VEGFR1,serine protease inhibitor,inhibin and CK7 in the pathogenesis of PIH.
