Objective:To study bacterial distribution and antimicrobial resistance of 489 strains of bacteria isolated from clinical urinary specimens of inpatients in department of kidney diseases of our hospital from 2001 to 2002,and propose rational use of antibiotics.Methods:Bacteria was isolated and identified by routine methods.Antimicrobial susceptibility was tested by K-B method.Results:in the 489 strains,there were307 strains of gram-regtive bacilli which account for 62.5%,mean while,there were 182 strains of gran-positive cocci which acconnt for 37.5%.The gram-negative bacilli mainly included K.pneumonice P.mirabilis and E.aerogenes.And the gram-positive cocci mainly included enterococcus and serum coagulase negative staphylococcus.The gram-negative bacilli were sensitive to imipenem and piperacillin/tazobactam,while the gram-positive cocci were sensitive to vancomycin and Teicoplamin.Conclusion:The urinary system infection is always induced by E.coli and Enterococcus.The periodical detection for bacterial resistance has an important significance for clinical treatment.

Objective:To monitor the rug resistance and epidemiology state of pseudomonas aeruginosa(PA)isolated clinical pa- tient.Methods:antimicrobial sensitivity tests were performed by K-B method and metallo-?-lactamases-producing PA was genotyped by the randomly amplified polymorphic(PAPD)assay.Results:Among24 strains resistant to imipenem.19(8%)strains produced metal enzyme which could be distingurished into 10 kinds of PAPD type.the type ability was 100%.There was same gene type strain.Isolated from three patient and there were two kinds of gene types. Among 2 strains isolated from the same patient at the different time.Conclusions:the K-B method could be used to determine metal enzyme,rapidly and eonviently. And PAPD could to be used in the molecular epidemiological study of PA.

Microcirculation disturbance and ischemia of the pancreas are important pathophysiological changes in the onset of acute pancrea-titis,and organ hypoperfusion is a risk factor for poor prognosis.During the first 12 to 24 hours after admission,fluid resuscitation is the most important medical treatment for the early stage of acute pancreatitis,and timely and rational fluid infusion helps to improve prognosis. However,there lacks high -quality clinical evidence for type of fluid,infusion speed,and monitoring methods,and more randomized con-trolled trials are needed.

As a mode of pay for performance,hospital value-based purchasing has been become widespread the US.Medicare managed to encourage the service providers to provide medical services with more value and quality.The implementation background,financing,payment mode and performance evaluation of hospital value-based purchasing were briefly introduced.In the payment reform of China,it also needed to focus on the medical service quality,learn from the performance evaluation system,incentive mechanism and multiple measurement,reasonably design the implementation scheme.

Wnt proteins,its receptors and regulators compose complex signaling pathways which are closely related to embryonic development,cell proliferation and differentiation,as well as tumour generation.In recent years,the involvement of Wnt signaling pathways in hepatocarcinogenesis has drawn the attention of international medical circles and been studied intensively.In this review,we summaries the interaction between Wnt signaling pathways and its regulators,the relationship between Wnt signaling pathways and cancerogenesis,angiogenesis,invasion and metabasis in hepatocellular carcinoma.

OBJECTIVE To observe the anti-infection and anti-pyretic effect in vivo of Minor Decoction of Bupleurum(Xiaochaihu Tang).METHODS The Streptococcus pneumoniae infection model in mice and endotoxin-induced feverish model in rats were prepared,Minor Decoction of Bupleurum was used to treat the experimental animals vs Baphicacanthus cusia Bremek.(Isatis tinctoria)granule in control unimals to observe death rate of infected animal and the changes in temperature of feverish animals.RESULTS Minor Decoction of Bupleurum had better effect on decreasing death rate of S.pneumoniae infected animal and on lowering the temperature of endotoxin-induced feverish animal,P

Objective Health promotion aims to empower people to enjoy good health by providing conditions at the micro-,meso-and macro-levels.So the organizational culture on which the target population rely in their daily lives should be considered as specific context for promoting their healthy behavior at the micro-level.The study of BANBANCHA,a specific form of sex industry in LZ city of southwest China,has revealed that it is characterized with culture of quasi-family and commercial sense.Accordingly,a relevant HIV prevention strategy has been developed,such as motivating the boss to participate in peer education,involving marketing discourse in health promotion,encouraging the target population to care for their own health,and integrating public and private topics into the health education activities.

Objective To study the effects of passive movement (PM) and electric stimulation(ES) on soleus of the tail suspended rats. Methods Seventy-two male Wistar rats(68～76g) were used in this experiment and divided into a normal control group, a model group (tail suspension), a ES group (tail suspension plus ES) and a PM group(tail suspension plus PM).The cross-sectional area of the muscle fibers and proportion of various types of muscle fibers in soleus were observed by histociemical staining of succinic dehydrogenase (SDH) and image pattern analyzer. Results The results showed that the cross-sectional area of all types of soleus muscle fibers in the PM and ES groups was significantly larger than that in the model group, with the area of the intermediate muscle fibers more significantly larger in particular. The proportion of the red fibers decreased and that of the intermediate fibers increased in the model group after one week of tail-suspension. Conclusion Passive movement and electrical stimulation could slow down the muscle atrophy of soleus of the tail-suspended rats.

By improving the existing pattern that different medical institutions with competition fragmentary health care mode,the bundled payment could improve the coordination and cooperation between medical institutions,improve the overall medical service quality and reduce medical service cost.It provided a helpful thought for the supply-side reform in health field in China.Foreign experience indicated that in order to implement bundled payment mode,China should build a complete medical service supply chain to promote integration of medical institutions;shift economic stimulus to economic constraints,build orderly competition environment;strengthen the construction of informatization and promote the applications of healthy big data.
