Economization of water,electricity and gas plays an important part in the construction of an economical hospital.The metering and accounting system for water,electricity and gas management in our hospital can rationally and accurately account the consumption of water,electricity and gas.Under this system,we have implemented quota management and cost control in the medical departments,efficiency assessment in the production and supply units,cost inclusion in the internal services unit,cost collection from the logistics support contractor units,and the maintenance of pipeline leakage,which has proved to be a set of effective and scientific solutions to the promotion of the efficiency of water,electricity and gas management in the hospital.

Objective To examine the cognitive function in healthy first-degree relatives (FDRs) of patients with bipolar Ⅰ disorder.Methods Cognitive function were studied in one hundred twenty healthy FDRs of patients with bipolar Ⅰ disorder and one hundred normal controls using digital symbol, digital span, visual reproduction, trail making test A (TMT-A) and trail making test B (TMT-B).Results Compared with normal controls, FDRs showed impairment in all indexes of the tests, including digital symbol, digital span (forward, reversed and forward + reversed), visual reproduction, TMT-A and TMT-B (t=-3.44、-4.23、-4.32、-4.98、-2.59、4.32、3.78, respectively, Ps≤0.01).By analysis of covariance (covariant: age and years of education), FDRs were still impaired in these indexes (P<0.05).Compared with sex-matched normal controls, male FDRs showed impairment in all indexes of the tests, but female FDRs only showed impairment in digital span (reversed, forward + reversed), TMT-A and TMT-B (P<0.05).Conclusions Attention, memory and executive function are impaired in healthy first-degree relatives of patients with bipolar Ⅰ disorder.

OBJECTIVETo assess the association of neural development-related genes LIS1and TSNAX with bipolar disorder in a Chinese Han population.

METHODSThree hundred and eight five patients (including 188 males and 197 females) from Guangzhou Brain Hospital with bipolar disorder meeting the Diagnostic and Statistic Manual of Bipolar Disorder (BDI) (Fourth Edition) criteria and 475 healthy controls from the local community were recruited. Ten single nucleotide polymorphisms (SNPs) of the LIS1 and TSNAX genes were genotyped by GoldenGate genotyping assay on an Illumina Beadstation 500 machine. Association analyses of SNPs and haplotypes were performed with Plink 1.07 software.

RESULTSAnalysis of the total sample has failed to find any association of SNP or haplotype of the two genes with BDI (P> 0.05). When patients were divided into subgroups with or without psychotic symptom, no significant association of the two genes was found with psychotic BDI or non-psychotic BDI (P> 0.05). No significant association was found between any SNP and haplotype of two genes and female BDI or male BDI, nor were significant association found between age of onset and LIS1 and TSNAX gene polymorphisms.

CONCLUSIONOur results indicated that LIS1 and TSNAX genes are not associated with susceptibility to bipolar I disorder in Chinese Han population.
