OBJECTIVE:To analyze and determine the compositions of monosaccharide in polysaccharide from leaves and twigs of Morus nigra from Xinjiang.METHODS:The polysaccharides in leaves and twigs of M.nigra were extracted by water and precipitated by ethanol then hydrolyzed into monosaccharide by using 2 mol?L-1 H2SO4.The monosaccharide was derivatized with 1-phenyl-3-methyl-5-pyrazolone(PMP) and determined by RP-HPLC. RESULTS:The polysaccharide in leaves and twigs of M.nigra were composed of mannose,rhamnose,glucuronic acid,galacturonic acid,glucose,galactose and arabinose etc. All the 7 monosaccharides were well-separated within 25 min. CONCLUSION:The method is simple and sensitive with accurate results,and it can be used for the quality control of leaves and twigs of M.nigra from Xinjiang.

Objective To observe the changes of serum lipids ,hs‐CRP ,MFG‐E8 and Klotho gene levels after rosuvatatin treatment in elderly patients with coronary heart disease complicating hyperlipidemia for investigating the action mechanisms of ro‐suvatatin and its application value .Methods Totally 129 elderly patients with coronary artery disease complicating hyperlipidemia in our hospital were randomly divided into two groups .The control group received only conventional treatment ,while on this basis the rosuvatatin group was given rosuvastatin 10 mg everyday ,with 2 months as a treatment cycle .Blood lipids ,hs‐CRP ,MFG‐E8 and Klotho gene levels before and after treatment were compared between the two groups .The regulation effect of rosuvatatin was investigated Results The blood lipod ,hs‐CRP ,MFG‐E8 and Klotho before treatment had no obvious difference between the two groups .The levels of TC ,LDL‐C and TG after treatment in the rosuvatatin group were significantly decreased compared with the control group ,while the HDL‐C level was significantly increased ,the differences were statistically significant (P<0 .05) .In addi‐tion ,the hs‐CRP level after treatment in the rosuvatatin group was significantly lower than that in the control group (P<0 .05) . Compared with the control group ,the levels of MFG‐E8 and Klotho after treatment in the rosuvatatin group were increased ,the difference was statistically significant (P<0 .05) .Conclusion Rosuvastatin could decrease the blood lipid and hs‐CRP levels ,up‐regulates the MFG‐E8 and Klotho levels ,alleviates the inflammatory reaction and has the anti‐vascular aging effect ,thus effectively treats the patients with coronary heart disease complicating hyperlipidemia .

Objective To investigate colonization status and risk factors of multidrug-resistant organisms (MDROs)in a surgical intensive care unit (SICU),and provide a basis for active clinical screening of MDROs. Methods From June 1,2013 to August 31,2013,patients who admitted to SICU≥24 hours were performed active screening,the colnization status of methicillin-resistant Staphylococcus aureus (MRSA)and extended-spectrumβ-lactamase-producing Escherichiacoli/Klebsiellapneumoniae (ESBL-E.coli/Kp)among patients were detected,re-lated risk factors were analyzed. Results When patients who admitted to SICU≤48 hours,the detection rate of MRSA and ESBL-E.coli/Kp was 1 1 .00% and 73 .00% respectively;when admitted to SICU>7 days,the increased detection rate of MRSA and ESBL-E.coli/Kp was 16.67% and 44.44% respectively. Patients stayed in hospital >7 days before admit-ting to SICU (OR95% CI:4.48 [1 .21-16.65 ])was an independent risk factor of carrying MRSA when admitting to SICU,APACHEⅡscore ≥16 (OR95% CI:6.36[1.47-27.54])was an independent risk factor of carrying MRSA 48 hours after admitting to SICU. Conclusion When patients admitted to SICU,the carrying rate of MDROs is high,isola-tion rate rises with prolonged length of SICU stay. Hospitals should carry out MDRO colonization screening proj ect among patients and implement effective isolation control measures to reduce the incidence of healthcare-associated infection.

To investigate the effect of acid and alkali stress on ginsenoside content of Panax ginseng, adventitious roots culture in bioreactors were incubated for 30 d and pH value was adjusted. Ginsenoside content increased by reducing or raising the pH in culture medium, the muxium ginsenoside content was determined on the 5th days after acid treatment and on the 7th days after alkali treatment. The result of histochemical localization of ginsenoside revealed that the red color from light to dark were found in the adventitious root tissue, and ginsenoside mainly located in the pericycle cells where appeared the dark red color.

To improve cell suspension culture system of Panax ginseng, the dynamic of cell growth and medium consumption were studied, and the effects of filter on the culture vessel, revolution number, and inoculation density on cell growth and ginsenoside accumulation were also investigated. The maximum cell growth and ginsenoside accumulation was found on the 20th days of suspension culture, therefore, 20 days were confirmed as a suitable culture period for mass production of ginsenoside. Cell growth and ginsenoside content were promoted when the culture vessel had a ventilated filter. Revolution speed during suspension culture affected cell growth, but not ginsenoside content, a peak of ginsenoside productivity was found in the treatment of 120 r x min(-1). Inoculation density also influenced cell growth and ginsenoside accumulation, inoculation density of 6 g was better than other inoculation densities, the ginsenoside content and productivity were up to 12.8 mg x g(-1) DW and 146.6 mg x L(-1), respectively.
