A general evaluation indexing system is constructed based on hospital specifics, in HR evaluation theory, on job orientation, HR competence, and by means of expert consultation and level of analysis. Four tier-1 indexes were earmarked as knowledge, basic competence, management capability, and research capability; 32 tier-2 indexes include education background, foreign language command, computer capability, legal knowledge, and professional knowledge, each having different weight. This indexing system enables hospitals to screen their management staff objectively, reliably and efficiently. Moreover, it serves as a reference not only for their recruitment, training, screening and promotion, but also for their personal development.

Aim To establish an ideal hyperlipidemia animal model by a new way.Methods 30 mice were randomly divided into control group, positive control group and model group.The mice of control group were only fed with a standard diet.Those of positive control group were fed with high fat diet.Those of model group were fed with a standard diet and enough milk.After 30 days the TG, TC, HDL-C and LDL-C of serum and hepatic and LI were detected and pathological changes in the liver of mice were observed microscopically.Results Compared with the control group, the mice of model group developed hyperlipidemia with LI and the serum and the hepatic TG, TC, LDL-C elevated significantly, while HDL-C were significantly lower.The histopathological research showed hepatocellular macrovesicular steatosis and hepatitis in the model group.Conclusion An ideal model of hyperlipidemia is successfully established with standard diet and milk fed to mice for 30 days.

Objective To understand the species diversity of ectoparasites on Niviventer confucianus in the surrounding areas of Erhai Lake.Methods Small mammals were randomly captured in 12 investigated sites surrounding Erhai Lake with baited mouse cages.The cage-traps were examined and re-baited each morning.Trapped small mammals were brought to the laboratory for identification according to color, body length, ear length, hind foot length.All ec-toparasites on the surface of the hosts were collected and identified.The constituent ratio(C), prevalence(P) and average ectoparasite abundance(A) were used to evaluate the prevalence and density of ectoparasites.Non-parametric Mann-Whitney U-test was used to test differences in the abundance and richness of ectoparasites between female and male hosts.Spearman correlation analysis was used to analyze the relationship between ectoparasites and the body param-eters of hosts.Results Eighty-nine individuals of N.confucianus were captured, of which 79% were found infested with 51 species of ectoparasites, including 31 species of chigger mites, 13 species of mesostigmatid(gamasid) mites, 4 species of fleas and 3 species of sucking lice.Walchia ewingi Fuller(66.2%), Laelaps turkestanicus Lange(38.5%), Paradoxopsyllus custodies Jordan(42.9% ) and Hoplopleura pacifica(80.1% ) were the most predominant species of chigger mites, gamasid mites, fleas, and sucking lice, respectively.Non-parametric Mann-Whitney U-test showed that there was no significant difference between male and female hosts on the species richness and abundance of total ec-toparasites, chigger mites, sucking lice, fleas or gamasid mites.Spearman correlation analysis showed that the abun-dance and species of total ectoparasites, chigger mites, sucking lice, fleas or gamasid mites were not correlated with the body weight of hosts.Conclusion There is a high speices diversity of ectoparasites on N.confucianus.Sucking lice, fleas, chiggers and gamasid mites are the main ectoparasites.

Objective To investigate the ecological niches of sucking lice (Phthiraptera: Anoplura) on the body surface of small mammal hosts and the co-evolutionary relationship between lice and mammal hosts in Yunnan Province. Method Thirty species of small mammals were captured and used as 30 resource sequences. The distribution and composition of the dominant 22 species of sucking lice on the body surface of the 30 species small mammal hosts were analyzed as the utilization proportion for each resource sequence. The niche breadth and proportional similarity were measured. SPSS 13.0 statistical software was used for analyzing the niche overlap matrix of sucking lice by hierarchical clustering analysis, and a dendrogram was made. Results The niche breadth was narrow for most species of sucking louse. Among the detected species, Hoplopleura pacifica showed the widest niche breadth, but only 0.1536. Indices of niche proportional similarity of most sucking lice were relatively small from 0.0005 to 0.4695. The 22 species of sucking lice were classified into 16 niche overlap groups, by ?=5.5, through a hierarchical clustering analysis for the niche overlaps, and the clustering process of most sucking lice was late. Conclusion The sucking lice have a high specificity for hosts, of which different species show an apparent niche divergence on host selection. The results reveal a high coevolution between sucking lice and the mammal hosts.

A total of 1140 medical workers from 8 public hospitals of secondary and tertiary levels in Anhui were surveyed with questionnaire. Their knowledge of the reform, acknowledgement of key points of the reform, desire of participating in the reform and other factors that may influence the reform were investigated as categorized by their hospital, position, title and age. This study comes up with such recommendations as reinforcing communications on public hospital reform, reforming the compensation mechanism to clarify government responsibilities, probing into a better model for multi-institution practice of certified physicians, and encouraging private capital to participate in medical service while ensuring its non-profit nature, and improving the performance appraisal mechanism to ensure incentives of medical workers. These recommendations aim to enable the health administrators in their decision making.

Objective To investigate gene polymorphisms and distribution features of glutathione Stransferase Omega-1 (GSTO 1 ) gene in Ala 140Asp site in 16 Chinese populations.MethodsA total of 1369 samples were from the human genome project(HGP)-the establishment and preservation program of Chinese minority genetic resources.The phenotypes of Ala/Ala (C/C),Ala/Asp (C/A),and Asp/Asp (A/A) of GSTO1 Ala140Asp were determined by polymerase chain reaction-restriction fragment length polymorphism(PCR-RFLP).With analysis of molecular variance(AMOVA),the genetic variation levels among nations and regions were analyzed by estimating the evolutionary distance of alleles or genotypes.ResultsOf the 1369 individuals analyzed,979 (71.51％) were carriers of the wild homozygous allele Ala/Ala(C/C),365 (26.66％) were heterozygotes Ala/Asp(C/A) and 25 (1.83％) were mutant homozygotes Asp/Asp(A/A),with an overall frequency of the GSTO 1 mutant allele A 15.16％ [ (365 +50)/( 1369 × 2)].AMOVA analysis showed that the difference was statistically significant(P ＜ 0.05) of genetic variations of GSTO1 gene Ala140Asp among the 14 ethnic groups,and was significant between the northem and southern populations (P ＜ 0.05 ).Conclusion In different regions and populations the GSTO1Ala140Asp mutant allele frequencies are different.

Objective To investigate and evaluate the polymorphism distribution of arsenic(+3 oxidation state)methyhransferase(AS3MT)5'-UTR VNTR in Chinese populations.Methods Genomic DNA was extracted from peripheral blood anti-coagulated with ACD of 1440 individuals in a standard phenol-chloroform protocol.The phenotypes of AS3MT 5'-UTR VNTR were determined by polymerase chain reaction(PCR)associated with agarose gel electrophoresis.Results Of the 1440 individuals,771(53.5%),426(29.6%),211(14.7%),16(1.1%)and 16(1.1%)were carriers of the V2/V3(AB/A2B),V3/V3(A2B/A2B),V2/V2(AB/AB),V2/V4(AB/A3B)and V3/V4(A2B/A3B)genotype,respectively.The AB(V2),A2B(V3)and A3B(V4)allele frequency was 41.9%,57.0%,1.1%respectively.The differences of AB(V2)and A2B(V3)allele frequency were all significant between the northern and southern populations respectively(χ2=23.39,χ2=33.28,P＜0.007).Conclusions In different regions the AB(V2)and A2B(V3)allele frequency is different,the AS3MT 5'-UTR VNTR polymorphism can be used to evaluate the susceptivity of arsenieosis.

OBJECTIVETo determine the role of asymmetric dimethylarginine (ADMA) in acute lung injury induced by cerebral ischemia/reperfusion (I/R) injury in rats.

METHODSAdult male SD rats were randomly divided into 4 groups, namely the sham-operated group (S), cerebral I/R model group, ADMA+I/R group, and dimethylarginine dimethylaminohydrolase (DDAH)+I/R group. In the latter 3 groups, acute lung injury was induced by left middle cerebral artery occlusion for 120 min. After a 24-h reperfusion, the rats were sacrificed and the activities of nitric oxide synthase (NOS) and contents of nitric oxide (NO) were measured using reductase and colorimetric assay. The mRNA and protein expressions of protein kinase C (PKC) and myosin light chain kinase (MLCK) in the lung tissues were detected with RT-PCR and Western blotting, respectively. The contents of ADMA in the bronchoalveolar lavage fluid (BALF) and blood flowing into and out of the lungs were measured by ELISA.

RESULTSCerebral I/R injury caused significantly elevated ADMA levels in the BALF and blood flowing into the lungs, and obviously lowered the NO concentration and NOS activity in the lung tissues (P<0.05). Following cerebral I/R injury, MLCK and PKC mRNA and protein expressions were significantly upregualted in the lung tissues (P<0.05). Exogenous DDAH obviously decreased the levels of ADMA in the BALF and blood flowing into the lungs, increased NO concentration and NOS activity, and down-regulated MLCK and PKC mRNA and protein expressions in lung tissues of rats with cerebral I/R injury (P<0.05).

CONCLUSIONADMA contributes to the development of acute lung injury following cerebral I/R injury in rats by upregulating MLCK and PKC expression. ADMA may serve as a novel therapeutic biomarker and a potential therapeutic target for acute lung injury induced by cerebral I/R injury.
