Guided by the innovation theory and ideology, the authors'hospital saw to it that the main line of innovative progress ran through the entire process of its development and set up a management engineering framework for innovation in six chief aspects. It managed to achieve “three firsts”, viz. the first to put forward in the domestic medical industry the suggestion of taking strategic actions so as to promote the construction of a clean and honest administration in the hospital; the first among hospitals of the armed forces to cultivate an “experimental plot” that partook of no money earmarked for national defense; and the first among large general hospitals at home to develop into a non profit hospital without government subsidies. It also attained remarkable results in the fight against SARS.

Objective To establish an assay for the detection of Streptococcus pneumoniae by real-time fluorescence quantititive polymerase chain reaction (PCR).Methods Special primers and probe for the autolysin A (lytA)gene were designed.The sensitivity and specificity of primers and probe were studied,and cut-off of cycle threshold was assayed.158 clinical specimens were confirmed by real-time fluorescence quantitative PCR and bacterial culture method.Results Primer and probe design for LytA gene could sensitively detect serotype Streptococcus pneumoniae strains of common pathogenic,and the sensitivity was 100 copies.Among 35 strains of Streptococcus pneumoniae,34 cases were detected to be positive for Streptococcus pneumoniae by real-time fluorescence quantitative PCR,while 1 case was detected to be negative;among 15 strains of non-Streptococcus pneumoniae, all were detected to be negative.Among the 158 clinical sputum specimens,34 cases with Streptococcus pneumoniae were detected by real-time fluorescence quantitative PCR,while only 10 cases with Streptococcus pneumoniae were detected by the culture method.White blood cells count and time in hospital of cases with Streptococcus pneumoniae were higher than those of cases without Streptococcus pneumoniae (P <0.05 ). Conclusion Real-time fluorescence quantitative PCR is a sensitive and specific assay for the detection of Streptococcus pneumoniae.It can be used for the diagnosis of Streptococcus pneumoniae.

In the new era, enhanced Party construction of public hospitals is the fundamental assurance for the success of Healthy China strategy. Based on field survey, in-depth interview, literature review and promotion of pilot practices, the Hospital Party Construction Guidance Committee of Guangdong Province staged a " Four Virtues" program to enhance Party construction at public hospitals in the healthcare system of the province. This program, featuring " leadership competency" , " Party branch capability" , " Party construction branding" , and " Unit showcases" , aims at the limited implementation and homogenization problems commonly found in Party construction at public hospitals. Promotion of successful pilot practices of several public hospitals effectively encouraged the " parallel development" of both medical service and Party construction, providing useful references for the hospitals in their reform/development and Party construction in the new era.

To study the effect of the osmotic stress in the microenvironment on the growth and metabolism of the encapsulated cells under aerobic condition, Osmo-sensitive yeast Y02724 and high-osmotic resistant yeast Hansel were used as models to explore the growth and metabolism state of the cells cultivated inalginate-chitosan-alginate (ACA) microcapsules. The changes of the yeast cells' specific growth rate, maximum product quantity and the secretion of ethanol and glycerol were analyzed. For Y02724, the yield of ethanol was increased in the ACA microenvironment compared to suspension cultivation. For Hansel, the maximum growth speed of microencapsulated cultivation had no obvious difference compared to the suspension cultivation. Moreover, after encapsulation, the production of glycerol was decreased for both Y02724 and Hansel compared to suspension cultivation. In conclusion, osmotic stress existed in the ACA microcapsules and affected the growth and metabolism of the cells.

Objective To analyze the relationship of neurocognitive impairments and 1 H MRS changes of the thalamus in patients with chronic hepatitis B virus related cirrhosis (HBV-RC).Methods Totally 28 patients with HBV-RC (cirrhosis group) and 28 well-matched healthy subjects (control group) were enrolled.All subjects underwent number connection test A (NCT-A) and the digit symbol test (DST) before MRS scanning.The ratios of peak area to each metabolite,including N-acetylaminosuccinic acid (NAA),choline (Cho),glutamine and glutamate (Glx),myoinositol (mI) and creatine (Cr) were calculated,respectively.Results Compared with control group,patients in cirrhosis group showed lower Cho/Cr and mI/Cr,higher Glx/Cr,prolonged NCT-A time and decreased DST scores (all P＜0.001).NCT-A completion time was negatively correlated with Cho/Cr and mI/Cr (r=-0.477,P =0.001;r=-0.695,P＜0.001) and positively correlated with Glx/Cr (r=0.665,P＜0.001).DST scores were positively correlated with Cho/Cr and mI/Cr (r =0.478,P =0.001;r=0.632,P＜0.001),and negatively correlated with Glx/Cr (r=-0.572,P＜0.001).Conclusion The neurocognitive impairments may be related to metabolic changes of the thalamus in patients with HBV RC.
