Objective To explore time difference attack therapy in Acinetobacter bauamnnii infection. Methods 67 patients with Acinetobacter bauamnnii were divided into two groups. The experimental group were first given Fosfomycin 4 g 5% GS 100 ml iv girt to finish within 60 min and then given Cefperazone/Sulbactam 4 g 0.9% NS 250 ml iv gitt immediately bid. The control group were given: Ampicillin/Sulbactam 3 g 0.9% NS 250 ml iv gitt (tid) + Ciprofloxacin 0.2 g iv girt (bid). The treatment course all was 11 days. Results The overall effective rate of experimental group methods was superior to that of control group(X2 =9.56 ,P =0. 023). Conclusion The Fos-fomycin Cefperazone/Sulbactam time difference attack therapy for the treatment of Acinetobacter the bauamnnii in-fection is a new way.

0.05),and the expression of HoxB5 in the model group tapered after the 7th day,but the expression of HoxB5 increased and reached the peak on the 7th day and expressed in a stable level in the control group and were significantly higher than those of model group(Pa

ObjectiveTo observe the effect of pioglitazone on the metabolism of glucose and lipid in patients with Impaired Glucose Regulation(IGR).Methods60 cases of IGR received conventional education on diabetes prevention,while the patients in intervention group(30 cases) accepted pioglitazone 15 mg once a day for 12 weeks.Blood pressure(BP),body weight,waist circumference,hip circumference were measured to calculate body mass index(BMI) and waist-hip ratio(WHR).The Fasting blood glucose(FBG),2 h postprandial blood glucose,glcosylated hemoglobin(GHb,HbA1C),fasting serum insulin(FINS),postprandial serum insulin(2hINS),total cholesterol(TC),triglyceride(TG),high-density lipoprotein cholesterol(HDL-C),low-density lipoprotein cholesterol(LDL-C),hepatic function,renal function were determined before and 12 weeks after intervention.ResultsAfter intervention,BP,BMI,FBG,2hBG,FINS,2hINS,HbA1C,TC,TG,LDL-C had been decreased significantly in intervention group(P<0.05 or P<0.01).There were significant differences between intervention group and control group(P<0.05 or P<0.01) in all indexes except body weight,WHR,hepatic function,renal function.ConclusionPioglitazone can obviously improve the metabolism of glucose and lipid in patients with IGR.

Objective To investigate the protective effect of edaravone against ischemiareperfusion injury in small-for-size rat liver grafts and its possible mechanisms. Methods 40 % small-for-size rat liver transplantation model was established by using modified two-cuff technique, adult male SD rats were used as donors and recipients, and 16 recipient rats were randomly divided into two groups (8 cases in each group), saline control group (control group) and edaravone treatment group (ED group). In the ED group, 3 mg/kg edaravone was given intravenously via penile vein 30 min before transplantation in the recipients. The same amount of saline was given in the control group at the same time points. Serum hepatic function (AST and ALT) and histopathological changes were analyzed; the contents of MDA and SOD, and hepatic myeloperoxidase (MPO) activity in liver grafts after 6 h were determined; and TNF-α levels at 6th h after reperfusion were measured by using enzyme-linked immunosorbent assay (ELISA method). Results As compared with control group,serum AST and ALT levels were significantly reduced at the 6th h after reperfusion in ED group (AST: 825. 50 5±72. 87 vs 1188. 03 ± 124. 04; ALT. 687. 40 5±72. 21 vs 988. 66 ± 91.07, P<0. 01 ).The content of MDA was lower and SOD level was higher in ED group significantly than in control group (P<0. 01). As compared with control group, hepatic TNF-α levels and MPO activity at the 6th h after reperfusion were significantly decreased in ED group (P<0. 01 ). Histopathological analysis revealed disruption of lobular architecture, apparent hepatocelluar degeneration accompanied by focal necrosis, significant edema, congestion and inflammatory cell infiltration in periportal area at the 6th h after reperfusion in control group, but minimal liver damage was observed in ED group. Conclusion Edaravone could ameliorate early ischemia-reperfusion injury in small-for-size liver grafts significantly.The protective mechanisms were mediated in part by increasing antioxidant ability, inhibiting lipid peroxidation, and down-regulating inflammatory reaction.

Extracurricular activities are necessary complementarity to curricular study and play an important role in medical education.Research and practice of how to develop the extracurricular activities in medical students were carried out,and good results were achieved in the aspect of the development of students' comprehensive quality and practical ability.

OBJECTIVEThe present study is concerning qualitative and quantitative detection of Poria cocos quality based on FT-near infrared (FT-NIR) spectroscopy combined with chemometrics.

METHODThe Poria cocos polysaccharides contents were determined by UV. Transmission mode was used in the collection of NIR spectral samples. The pretreatment method was first derivation and vector normalization. Then principal component analysis (PCA) was used to build classification model and partial least square (PLS) to build the calibration model.

RESULTThe results showed that conventional criteria such as the R, root mean square error of calibration (RMSEC), and the root mean square error of prediction (RMSEP) are 0.944 0, 0.072 1 and 0.076 2, respectively. The misclassified sample is 0 using the qualitative model built by PCA.

CONCLUSIONThe prediction models based on NIR have a better performance with high precision, good stability and adaptability and can be used to predict the polysaccharose content of Poria cocos rapidly, which can provide a fast approach to discriminate the different parts of Poria cocos.

In this study, solvent evaporation method was used to preparing baicalin ethylcellulose microspheres for intranasal administration. The prepared microspheres were round with certain rough surface. The average drug loading and entrapment efficiency was (33. 31 ± 0. 045)% , (63. 34 ± 0. 11)% , respectively. As the characteristic crystalline peaks of baicalin were observed in the microspheres sample, the result of X-ray diffractometric analysis indicated that the baicalin was present in crystalline form after its entrapment in ethylcellulose matrix. By investigating the thermogram of microspheres sample, it was found that endothermic peak of baicalin was shifted from 211. 8 °C to 244. 2 °C and associated with the first broad endothermic peak of ethylcellulose. This could confirm that baicalin was loaded into ethylcellulose, nor simply physical mixture. The powder flowability test exhibited that the specific energy of microspheres was 3. 57 mJ . g-1 and the pressure drop was 2. 22 mBar when air kept the speed of 2 mm . s-1 through the powder bed with the force was 15 kPa. The consequence of the baicalin in vitro released from microspheres showed that the pure baicalin sample displayed faster (90%) release than microspheres sample (75%) in 7 h. Fitting model for release curve before 7 h, the results showed that the pure baicalin sample and the microsphere sample accorded with first order model (R2 = 0. 990 4) and Riger-Peppas model(R2 = 0. 961 2), respectively. Ex vivo rabbit nasal mucosa permeability experiment revealed that the value of cumulative release rate per unit area of the microsphere sample was 1. 56 times that of the pure baicalin sample. This provided the foundation for the in vivo pharmacokinetic study.
