Objective To observe the results of broth dilution method and disc diffusion method to test the synergistic effect of Reduning and cefoperazone sodium / sulbactam sodium(SCF) on extensive drug resistant Acinetobacter bauman (XDR-AB) in vitro environment ,and compare their compliance to guide the clinical medication .Methods A total of 12 strains of XDR-AB from infec-tion patients in our hospital in 2015 were collected ,the strain was sub cultured .Firstly ,observe the minimum inhibitory concentra-tion (MIC) of SCF and Reduning on XDR-AB alone and in combination by broth dilution method .And then judge the synergy effects through calculation .Secondly ,the inhibition ring diameter and the synergy effects was detected using the disc diffusion meth-od .Results The MIC of Reduning and SCF in combination on XDR-AB was declined compared with them alone .The Fractional in-hibitory concentration of Reduning and SCF in combination on XDR-AB were equal or less than 0 .5 ,they had synergistic effect on XDR-AB .The inhibition ring diameter of Reduning was 10 mm tested by disk diffusion method .Different strains of XDR-AB on SCF bacteriostatic annulus diameter difference ,5 strains were 15 mm ,3 strains were 16 mm ,and 4 strains were 17 mm .Reduning and SCF appeared synergistic effect according to the inhibition ring diameter expanded when they effected on XDR -AB in combina-tion .Conclusion In vitro ,Reduning combined with SCF on XDR-AB has good synergistic effect .Compared with broth microdilution checkerboard dilution method ,disk diffusion method is more simple and convenient ,but it has a certain subjective on judging re-sults ,which is better to operate by experienced person .

Anatomic hepatic resection not only enables enough tumor-free resection margin,but also guarantee the maximal remnant of normal liver tissue.A 61-year-old male patient with hepatic cancer was admitted to the Affiliated Hospital of Hainan Medical College in February 2012.Multiple space-occupying lesions were found in segment Ⅵ,Ⅶ and Ⅷ by computed tomography (CT).The results of CT volumetry analysis showed that the left hemihepatic volume was lesser than the minimal limit of survival,so anatomic hepatic segmentectomy of Ⅵ,Ⅶ and Ⅷ with preservation of segment Ⅴ was designed to guarantee the maximal remaining of normal liver tissue.Glisson's pedicle transection was used twice to divide the right hemihepatic Glisson's pedicle,segment Ⅵ and Ⅶ Glisson's pedicle,respectivley,then the resection line was determined,and anatomical hepatic segmentectomy of Ⅵ,Ⅶ and Ⅷ was completed.With the procedures adopted,the hepatic ischemia reperfusion injury and hemodynamic instability were maximally reduced during operation.

AIM: To investigate the protective effects of ulinastatin on the rats with paraquat-induced acute lung injury and its mechanisms .METHODS:The Wistar rats ( n=108 ) were randomly divided into control group , pa-raquat group and ulinastatin group .The rats in paraquat group and ulinastatin group were given paraquat by gavage , while the rats in control group were given sterile saline by gavage .The rats in ulinastatin group were also given ulinastatin treat-ment.The serum levels of MDA, SOD, IL-6, IL-10 and TNF-αwere measured after 1 d, 3 d, 7 d, 14 d, 21 d and 28 d. The expression levels of p 38 MAPK, MMP-2 and TIMP-1 in the lung were also measured .RESULTS:The levels of SOD in 1 d, 3 d and 7 d in paraquat group and ulinastatin group were significantly lower than those in control group ( P<0.01).The level of SOD in ulinastatin group was significantly higher than that in paraquat group (P<0.05).The levels of MDA, IL-6, IL-10 and TNF-αin 1 d, 3 d and 7 d in paraquat group and ulinastatin group increased compared with con-trol group (P<0.01), and those in ulinastatin group were significantly lower than those in paraquat group (P<0.05). The levels of p38 MAPK and TIMP-1 in 1 d, 3 d, 7 d, 14 d, 21 d and 28 d in paraquat group and ulinastatin group were higher than those in control group (P<0.01), and those in ulinastatin group was significantly lower than those in paraquat group ( P<0.05) .The level of MMP-2 in 1 d, 3 d, 7 d, 14 d and 21 d in paraquat group and ulinastatin group increased compared with control group (P<0.01), and that in ulinastatin group was significantly lower than that in paraquat group (P<0.05).CONCLUSION:Ulinastatin protects the lung tissues of rats from paraquat-induced acute lung injury by in-hibiting p38 MAPK signaling pathway and ameliorating inflammatory and oxidative responses .

ObjectiveTo investigate the effect of transforming growth factor-β1 (TGF-β1) antibody on peripheral neural fibrosis after chronic entrapment.MethodsA total of 75 rats were randomly divided into three groups, ie, Group A (sham operation, only the sciatic nerve exposed), Group B (compression only, treated with sciatic nerve entrapment) and Group C (compression plus antibody injection).Electron microscopy, immunohistoehemistry, RT-PCR and Western blot were performed to observe the morphological changes of the compressed nerve tissue and to determine the level of TGF-β1 , collagen Ⅰ and collagen Ⅲ at 2, 4, 6, 8, 10 weeks after sciatic nerve compression, respectively.Results The levels of TGF-β1 , types Ⅰ and Ⅲ collagen protein were increased significantly in the Group B compared with that in the Group A, when the expression of TGF-β1 was increased in the early phase of the compression, reached the peak at the 4th week, and then decreased slowly.The expressions of collagenⅠand collagen Ⅲ were increased after compression, reached a peak at the 6th week and then maintained a relatively high level.The number of the fibrous tissues was decreased significantly and the content of types Ⅰ and Ⅲ collagen protein declined in the Group C, with statistical difference compared with the Group B (P ＜ 0.05).ConclusionsPeripheral nerve fibrosis can be caused by chronic nerve compression.TGF-β1 plays an important role in effectively inhibiting the collagen synthesis and ameliorating the nervous fibrosis of the protein following peripheral nervous entrapment.
