RESUMEN
OBJECTIVE@#To investigate the association of genetic polymorphisms of norepinephrine metabolizing enzymes with postpartum depression and analyze the risk factors for postpartum depression in women following cesarean section.@*METHODS@#A total of 591 Chinese woman of Han Nationality undergoing caesarean section were enrolled in this study. The diagnosis of postpartum depression was established for an Edinburgh Postnatal Depression Scale (EPDS) score ≥9. For all the women without antepartum depression, the genotypes of catechol-O-methyltransferase (COMT; at 5 sites including rs2020917 and rs737865) and monoamine oxidase A (rs6323) were determined using Sequenom Mass Array single nucleotide polymorphism (SNP) analysis. We analyzed the contribution of the genetic factors (SNPs, linkage disequilibrium and haplotype) to postpartum depression and performed logistic regression analysis to identify all the potential risk factors for postpartum depression and define the interactions between the genetic and environmental factors.@*RESULTS@#The incidence of postpartum depression was 18.1% in this cohort. Univariate analysis suggested that COMT polymorphism at rs2020917 (TT genotype) and rs737865 (GG genotype) were significantly correlated with the occurrence of postpartum depression ( < 0.05). Logistic regression analysis showed that COMT polymorphism at rs2020917 (TT genotype) and rs737865 (GG genotype), severe stress during pregnancy, and domestic violence were the risk factors for postpartum depression ( < 0.05); no obvious interaction was found between the genetic polymorphisms and the environmental factors in the occurrence of postpartum depression.@*CONCLUSIONS@#The rs2020917TT and rs737865GG genotypes of COMT, stress in pregnancy, and domestic violence are the risk factors for postpartum depression.

RESUMEN
To explore the state of domestic academic research on hospital administration, the authors, using the descriptive statistical method, investigated the literature on hospital administration included by CBMdisc from 1980 to 1998. The results are as follows. In the past 19 years, the output of literature on hospital administration has been growing steadily. The distribution of such literature has been rather dispersed. There lacks a specialized and ampre- hensive database of such literature. Chinese Journal of Hospital Administration and Chinese Hospital Administration are two major professional periodicals devoted to literature on hospital administration, publishing one fifth of the literature in this aspect. And Chinese Journal of Hospital Administration, the chief and most important key periodical devoted to literature on hospital administration, has become a professional periodical which is indispensable and of first choice to hospital administration personnel.

RESUMEN
Hospital building intelligentized system is an important part of digital hospital. Innovative theory in technique integration and service idea of "taking sufferers as center" is incarnated by its design and its development direction of current hospital building. The concept and design principle of intelligentized system in hospital architecture construction are discussed; the composing and function of intelligentized system are also expounded; characteristic and application effect of the system in hospital architecture are analyzed.
RESUMEN
As a chief part of hospital information system, the expendable management system plays an important role in expendable normalization, scientific management, efficiency improvement, labor lessening and mistake reduction. This paper mainly introduces the design of expendable network request system based on "No.1 Military" HIS and its main function as well as characteristics.
