Objective To explore the MRI appearances of tuberculosis of myelon and spinal meninges,and to study the value of MRI in diagnosis of this disease.Methods The imaging appearances of tuberculosis of myelon and spinal meninges tuberculosis in 8 cases were reviewed.All cases underwent plain MRI and contrast-enhanced MRI examinations.Results In 8 cases,there were myelonic tuberculosis in 3,myelonic tuberculosis accompanied with spinal meninges tuberculosis in 2 and spinal meninges tuberculosis in 3.Myelonic tuberculosis appeared as intramedullary tuberculous granuloma in 2,granulitis in 1 and tuberculous myelitis in 2.The appearances of MRI were spinal cord swelling,low signal intensity on T1WI and high signal intensity on T2WI.On contrast-enhanced MRI,the lesions were circular enhancement,military nodules or non-enhancement.The typical MRI appearances of spinal meningeal tuberculosis showed spinal meninges generally thickened,narrowing or closing of subarachnoid cavity,on contrast-enhanced MRI,the lesions were tubiform enhancement of sagittal images or circular enhancement of axial images.All cases had active tuberculosis in neighbourhood organ or tissue.Conclusion The MRI appearances of tuberculosis of myelon and spinal meninges are representative,the definite diagnosis of which can be made when the MRI appearances in combination with the history of the patients and the active tuberculosis of neighbourhood organ or tissue.

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.

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 explore the risk factors of neonatal necrotizing enterocolitis(NEC)and assess the effect of prophylactic use of probiotics(Bifico)in prevention of NEC and observe changes of weight.Methods Five hundred and twenty-four cases of prematures who were inpatients were divided into 2 groups randomly(prevention group,n=276,no-prevention group,n=248)and the morbidity of NEC and the increase of eight during hospitalization were observed.A case-control study and conditional Logistic regression model multifactorial analysis were made to 20 cases NEC neonates and 80 cases non-NEC neonates.Results The prevention group(276 cases)had 5 cases of NEC and the average weight increase was(8.114?8.137)g/d,the no-prevention group 248 cases had 17 cases of NEC,and the average weight increase was(6.595?5.337)g/d.The occure rate of NEC in prevention group was significantly lower than that of no-prevention group(?2=5.57 P

OBJECTIVETo provide a new material for producing the Rhodiolasachalinensis products, the effect of methyl jasmonate (MeJA) on callus biomass and effective compound accumulation of Rhodiolasachalinensis was studied.

METHODThe calluses-cultured in 3 L-air lift balloon type bioreactor were treated with MeJA after 20 d of bioreactor culture and the effect of MeJA concentration and treatment days on callus biomass, salidroside or polysaccharide accumulation and superoxide dismutase (SOD) and peroxidase (POD) activities were investigated.

RESULTThe callus biomass was not significantly different after MeJA treatment (125) for 0-6 d but obviously decreased after 6 d treatment. The maximum salidroside or polysaccharide contents and SOD or POD activities were found after 4 d treatment of MeJA. MeJA concentration significantly affected callus biomass and effective compound accumulation, biomass decreased at MeJA concentrations higher than 125 μmol x L(-1). However, the effective compound contents were determined at higher MeJA concentration, and the highest salidroside and polysaccharide accumulation was found at 225 and 275 μmol x L(-1) MeJA, respectively and the maximum SOD and POD activities was found at 225 μmol x L(-1) MeJA. The effective compound contents in callus were compared with field-grown plants. Salidroside contents in calluses were 1.1-fold and 2. 4-fold more than in plant roots and stem or leave, respectively. Polysaccharide content in calluses were 3. 6-fold and 8.0-fold more than in plant roots and stem or leave, respectively.

CONCLUSIONSalidorside and polysaccharide in Rhodiolasachalinensiscalluses improved by MeJA treatment, 225 μmol x L(-1) MeJA and 4 d treatment were optimal. The effective compound contents in callus were obviously higher than in field-grown plants. Therefore, bioreactor culture is efficient for obtaining mass effective compounds of Rhodiolasachalinensis by culturing calluses. This method could provide an alternative material source for production of Rhodiolasachalinensis products.
