Objective To investigate the effects of sevoflurane pretreatment on renal ischemia-reperfusion (I/R)-induced apoptosis in kidney in rats. Methods Thirty pathogen-free male SD rats weighing 220-260 g were randomized into 3 groups (n=10 each):group control (group C);group I/R and group sevoflurane(group S). Renal I/R was induced by clamping the left renal pedicle for 45 min in I/R and S groups. In group S inhalation of 2.2% sevoflurane in O2 was started at 30 min before operation and maintained throughout the experiment.Venous blood samples were taken at 3 h of reperfusion for determination of serum BUN and Cr concentrations. The animals were then sacrificed and the left kidneys were removed for microscopic examination, detection of apoptosis(by TUNEL)and determination of heme oxygenase-1(HO-1) mRNA and protein expression (by RT-PCR and Western blot).Results Renal I/R significantly increased serum BUN and Cr concentrations, apoptotic index(percentage of apoptotic cells) and the severity of necrosis of renal proximal convoluted tubules (0=normal,4=necrosis of whole segment of proximal convoluted tubules).Sevoflurane inhalation attenuated the I/R-induced changes mentioned above.HO-1 mRNA and protein expression was up-regulated by I/R and HO-1 mRNA expression was further up-regulated by sevoflurane inhalation.Conclusion Sevoflurane pretreatment can protect kidney against I/R injury by attenuating cell apoptosis.Up-regulation of HO-1 mRNA expression may be involved in the mechanism.

To study the interaction of drugs of different properties, namely puerarin, borneol and catalpol in the process of in- clusion, in order to explore the inclusion regularity of multi-component and multi-property traditional Chinese medicine compound in- clusions. With HP-β-CD as the inclusion material, the freeze-drying method was used to prepare the inclusion. The inclusion between puerarin, borneol and catalpol was tested by measuring the inclusion concentration, DSC and X-ray diffraction. According to the find- ings, when insoluble drugs puerarin and borneol were included simultaneously, and puerarin was overdosed, puerarin included was almost equal to puerarin included, and borneol was not included. When puerarin was under-dosed, and HP-β-CD was overdosed, borne- ol was included, and the simultaneous inclusion was lower than the separate inclusion of borneol. When water-soluble drug catalpol was jointly included with puerarin or borneol, the simultaneous inclusion was almost the same with their separate inclusion, without charac- teristic peak of catalpol in DSC and X-ray diffraction patterns. There is a competition in the simultaneous inclusion between water-solu- ble drugs puerarin and borneol and a stronger competition in puerarin. The water-soluble drug catalpol could be included with HP-β-CD with no impact on the inclusion of puerarin or borneol.

To explore the epidemiological character of Methicillin-resistant Stapkylococcus aureus (MRSA) by the phenotyping and genotyping motheds and to investgate the source, transmission, and the spread of nosocomial MRSA infection, consequently, reducing the nosocomial infection of MRSA. In this study, 19 MRSA strains were isolated from patients and environment in a hospital in two months. Patterns of resistantce against 16 antimicrobial agents and pulsed-field gel electrophoresis ( PFGE) of these strains were analyzed to find the relationship among those isolates Clustering analysis was made from the patterns. Some isolates with high homology was found in 19 MRSA, 11 of them belong to type A, and 8 of them belong to the same subtype A1. They were endemic in burn ward, oncological ward and ICU. In addition, 4 isolates were clustered into group B, all found in the same ward of burn unit Thus, our results indicated a outbreak of MRSA ( A type) in this hospital and the potential prevalence of MRSA (B type) , which might be mediated by health care stuff. It is essential to enhance the infection control implementation and to utilize the PFGE genotyping system for the real-time surveillance of MRSA.

Objective To investigate the clonal relatedness of A.baumannii isolates from senile patients by conducting cross-sectional and longitudinal studies on antimicrobial susceptibility profiling and genomic diversity.Methods Cross-sectional study was done among the 170 non-repetitive A.baumannii isolates which were collected from senile patients during two years.Longitudinal study was conducted among 77 A.baumannii collected from 8 senile patients within longtime hospitalization.Results 75.3 ％ of the 170 isolates were non-susceptible to carbapenems,and the phenotype were XDR or MDR which spread evenly all over the senile wards.The isolates belonged to 36 pulsotypes determined by PFGE.Groups Ⅰ (contain119 isolates) were major epidemic strains,which were CRAB with XDR phenotype.In longitudinal study,comparison of pulsotypes was performed for each patient and all isolates were clustered into group Ⅰ except one isolate.All the 77 isolates were XDR.Conclusion Extensive drug-resistance of A.baumannii was a serious problem in the gerontal wards.Clone dissemina tion was the most important style of XDR strains spread.Horizontal infection control measures to interrupt person-to-person transmission should be reinforced to reduce the further spread of XDR A.baumannii.

Objective To investigate the differentiatial diagnostic value of 99Tcm-methoxyisobutylisonitrile ( MIBI ) SPECT combined with localizable CT in the evaluation of oxygen intervention for suspicious lung lesions,and to establish a cost-effective imaging modality in the detection of malignant lung lesions.Methods From September 2008 to March 2009,47 consecutive patients with suspicious malignant lung lesions underwent 99Tcm-MIBI SPECT/CT prospectively. Patients with suspicious pneumonia were treated with antibiotics for about 4 d before imaging. All patients were cannulized with a nostril tube for oxygen inhalation before 99Tc-MIBI injection. SPECT combined with localizable CT of the chest was performed at 10 min and 2 h after 99Tcm-MIBI injection. The uptake ratios of lesion to contralateral normal lung parenchyma(early uptake ratio:EUR and delayed uptake ratio:DUR) were compared using independent-samples ttest. In addition,the diagnostic efficiency of uptake ratios of lung lesions was analyzed with receiver operating characteristic (ROC) curve. Results Forty-seven patients ( primary lung cancers:32,metastatic tumors of the lung:4,benign lung diseases:11 ) had 51 lung lesions,including 39 malignant and 12 benign lung lesions. The sensitivity,specificity,accuracy,positive predictive value (PPV),and negative predictive value (NPV) were 94.9% (37/39),83.3% ( 10/12),92.2% (47/51),94.9% (37/39) and 83.3% ( 10/12),respectively. The EUR of malignant lesions was 2.95 ± 1.16,whereas of benign lesions was 1.43 ±0.33. The DUR of the malignant lesions was 3.19 ± 1.74,whereas of benign lesions was 1.60 ±0.32. Both EUR and DUR were significantly different between malignant and benign lung lesions,respectively (t= -4.44,-3.12,respectively,both P＜0.01). The ROC curve showed that EUR value ≥1.625 provided the sensitivity of 97.4% (38/39) and specificity of 83.3% (10/12); DUR value ≥ 1.75provided the sensitivity of 94.9% (37/39) and specificity of 83.3% (10/12). Conclusion 99Tcm-MIBI SPECT combined with localizable CT imaging in oxygen intervention has a potential value in differentiating malignant from benign lung lesions.
