| 4 | Expression of nuclear factor-KB in hepatocellular carcinoma and its relation with the X protein of hepatitis B virus显示文摘AIM In this study we investigated therelationship of the X protein of HBV and nuclearfactor-KB (NF-κB) and the expression of NF-KB inhuman hepatocellular carcinoma tissues.METHODS Immunohistochemistry SP methodwas used to detect the expression of NF-κB and the X protein of HBV in human hepatocellularcarcinoma tissues of 52 cases. Gene transfectionmediated by lipofectamine was used to transfectthe eukaryotic expression vector pCDNA3. 1-HBXof HBV x gene into human hepatocellularcarcinoma cell line HCC-9204 and NF-κB wasdetected.RESULTS NF-κB was widely expressed inhuman hepatocellular carcinoma tissues in atotal of 52 cases and its expression was relatedto the X protein of HBV. NF-KB was localizedboth in the cytoplasm and . The nuclei ofhepatocellular carcinoma cells in 11 cases whichwere positive for the X protein of HBV while in 41cases negative for the X protein of HBV, NF-Kbwas only localized in the cytoplasm ofhepatocellular carcinoma cells but translocatedto the nuclei of hepatocellular carcinoma cellsafter the eukaryotic expression vectorpCDNA3.1-HBX was transfected into HCC-9204cells.CONCLUSION This study strongly suggeststhat the nuclear factor NF-KB is widely expressedin hepatocellular carcinoma tissues in differentstyles according to the expression of the Xprotein of HBV. NF-κB is abnormally activated inhepatocellular carcinoma, which is probablyrelated to the X protein of HBV. The X protein ofHBV can activate NF-κB to translocate into nucleiof hepatocellular carcinoma cells. | Shuang Ping Guo~1 Wen Liang Wang~1 Yu Qiang Zhai~2 Yi Ling Zhao~1 ~1Department of Pathology,Xijing Hospital of the Fourth Military Medical University,Xi’an,China ~2Department of Urology,the Central Hospital of Xi’an,China | 2001 | World Journal of Gastroenterology2001，7，3： | 55 |
| 5 | Recovery of Iron From High-Iron Red Mud by Reduction Roasting With Adding Sodium Salt显示文摘Red mud is the waste generated during aluminum production from bauxite, containing lots of iron and other valuable metals. In order to recover iron from red mud, the technology of adding sodium carbonate-reduction roasting-magnetic separation to treat high-iron red mud was developed. The effects of sodium carbonate dosage, reduction temperature and reduction time on the qualities of final product and the phase transformations in reduction process were discussed in detail. The results showed that the final product (mass percent), assaying Fe of 90.87% and Al2O3 of 0.95% and metallization degree of 94.28% was obtained at an overall iron recovery of 95.76% under the following conditions of adding 8% sodium carbonate, reduction roasting at 1 050 ℃ for 80 min and finally magnetic separation of the reduced pellets by grinding up to 90% passing 0.074 mm at magnetic field intensity of 0.08 T. The XRD (X-ray diffraction) results indicated that the iron oxides were transformed into metallic iron. Most of aluminum mineral and silica mineral reacted with sodium carbonate during the reduction roasting and formed nonmagnetic materials. | ZHU De-qing, CHUN Tie-jun, PAN Jian, HE Zhen (School of Minerals Processing and Bioengineering, Central South University, Changsha 410083, Hunan, China) | 2012 | Journal of Iron and Steel Research(International)2012，19，8： | 38 |

| 10 | Association between vascular endothelial growth factor and metastasis after transcatheter arterial chemoembolization in patients with hepatocellular carcinoma显示文摘BACKGROUND: Hypoxia up-regulates vascular endothelialgrowth factor (VEGF) and stimulates the growth of hepa-tocellular carcinoma (HCC) cells. This study was designedto investigate the association between changes in plasmaVEGF levels after transcatheter arterial chemoembolization(TACE) and HCC progression, especially in relation tometastasis.METHODS: Plasma VEGF levels were measured by quati-tative sandwich enzyme-linked immunosorbent assay(ELISA R&D system). Plasma VEGF levels were measuredbefore, 3 days and 4 weeks after TACE in 30 patients withHCC. The development of metastasis was evaluated at theend of the third month after TACE.RESULTS: The plasma VEGF levels of the 30 patients withHCC were 154.47±90.17 pg/ml. The total plasma VEGFlevels after TACE increased compared with their basal levels(P<0.05), and the plasma VEGF levels had a tendency toincrease in patients with heterogenous uptake of iodizdoiland portal vein thrombosis. Follow-up for six monthsshowed metastatic foci in 20 patients (74%) with increasedplasma VEGF, but none of the patients with decreased plas-ma VEGF developed metastasis.CONCLUSION: Increased plasma VEGF expression is asso-ciated with the development of metastasis in HCC after TA-CE. | Zheng-Ping Xiong, Shu-Ren Yang, Zhao-Yu Liang, En-Hua Xiao, Xiao-Ping Yu,Shen-Ke Zhou and Zi-Shu Zhang, Department of Radiology , Hunan Provincial TumorHospital.

| 11 | Production of proinflammatory cytokines in the human THP-1 monocyte cell line following induction by Tp0751,a recombinant protein of Treponema pallidum显示文摘The tissue destruction characteristic of syphilis infection may be caused by inflammation due to Treponema pallidum and the ensuing immune responses to the pathogen.T.pallidum membrane proteins are thought to be potent inducers of inflammation during the early stages of infection.However,the actual membrane proteins that induce inflammatory cytokine production are not known,nor are the molecular mechanisms responsible for triggering and sustaining the inflammatory cascades.In the present study,Tp0751 recombinant protein from T.pallidum was found to induce the production of proinflammatory cytokines,including TNF-α,IL-1βand IL-6,in a THP-1 human monocyte cell line.The signal transduction pathways involved in the production of these cytokines were then further investigated.No inhibition of TNF-a,IL-1β,or IL-6 production was observed following treatment with the SAPK/JNK specific inhibitor SP600125 or with an ERK inhibitor PD98059.By contrast,anti-TLR2 mAb,anti-CD14 mAb,and the p38 inhibitor SB203580 significantly inhibited the production of all three cytokines.In addition,pyrrolidine dithiocarbamate (PDTC),a specific inhibitor of NF-κB,profoundly inhibited the production of these cytokines.Tp0751 treatment strongly activated NF-κB,as revealed by Western blotting.However,NF-κB translocation was significantly inhibited by treatment with PDTC.These results indicated that TLR2,CD14,MAPKs/p38,and NF-κB might be implicated in the inflammatory reaction caused by T.pallidum infection. | LIU ShuangQuan1,2,WANG ShiPing1,WU YiMou3,ZHAO FeiJun3,ZENG TieBing3,ZHANG YueJun3,ZHANG QiuGui2 & GAO DongMei1 1 Department of Parasitology,Xiangya School of Medicine,Central South University,Changsha 410078 ,China 2 The First Affiliated Hospital,University of South China,Hengyan 421001,China 3 Department of Microbiology and Immunology,University of South China,Hengyan 421001,China | 2010 | Science China(Life Sciences)2010，53，2： | 28 |

| 14 | On the new results of global attractive set and positive invariant set of the Lorenz chaotic system and the applications to chaos control and synchronization显示文摘Constructing a family of generalized Lyapunov functions, a new method is proposed to obtain new global attractive set and positive invariant set of the Lorenz chaotic system. The method we proposed greatly simplifies the complex proofs of the two famous estimations presented by the Russian scholar Leonov. Our uniform formula can derive a series of the new estimations. Employing the idea of intersection in set theory, we extract a new Leonov formula-like estimation from the family of the estimations. With our method and the new estimation, one can confirm that there are no equilibrium, periodic solutions, almost periodic motions, wandering motions or other chaotic attractors outside the global attractive set. The Lorenz butterfly-like singular attractors are located in the global attractive set only. This result is applied to the chaos control and chaos synchronization. Some feedback control laws are obtained to guarantee that all the trajectories of the Lorenz systems track a periodic solution, or globally stabilize an unstable (or locally stable but not globally asymptotically stable) equilibrium. Further, some new global exponential chaos synchronization results are presented. Our new method and the new results are expected to be applied in real secure communication systems. | LIAO Xiaoxin 1, 2, 3 , FU Yuli 4 & XIE Shengli 4 1.

| 15 | The Aging Feature of Al-L-Cu-Mg-Zr Alloy Containing Sc显示文摘The aging behaviors of Al 1.42%Li 2.41%Cu 0.93%Mg 0.073%Zr 0.17%Sc(mass fraction, the same below) alloy at room temperature, 160 ℃ , and 160 ℃ after 8% pre deformation were studied respectively by hardness measurement. The microstructure of the alloy in various aging conditions was observed by TEM. The results show that the main precipitations of the alloy in quenching condition are the particles containing Sc and Zr which have certain coherent relation with the matrix. Addition of Sc in Al Li Cu Mg Zr alloy will be favorable to promoting precipitation. The particles can serve as preferred nucleation sites for δ′ phases which accelerate the aging hardening rate at initial aging. The main hardening phases of the alloy aged at 160 ℃ are δ′ and δ′/β′ composite precipitates. The size of the composite precipitates is very small (nanometer size). The composite precipitates will preclude efficiently the formation concentrative slip location and will improve the mechanical properties of the alloy. S′ phase will occur in the alloy aged at 160 ℃ after 8% pre deformation. It is found that 8% pre deformation has no obvious influence on the precipitation of the composite phase. | TAN Cheng yu,ZHENG Zi qiao,XIA Chang qing,LIANG Ying (Department of Materials Science and Engineering, Central South University of Technology, Changsha 410083, China) | 2000 | Journal of Central South University2000，12，2： | 22 |

| 18 | Serum thymosin β4 levels in patients with hepatitis B virus-related liver failure显示文摘AIM:To investigate whether serum thymosinβ4 can provide diagnostic or prognostic information in liver failure patients caused by chronic hepatitis B virus(HBV) infection. METHODS:Serum thymosinβ4 levels were measured in 30 patients with acute-on-chronic liver failure(ACLF), 31 patients with chronic liver failure(CLF),30 patients with compensated liver cirrhosis(CR)and 32 patients with chronic hepatitis B and 30 healthy controls.Serum thymosinβ4 levels were measured by enzyme-linked immunosorbent assay and Child-Pugh and model for end-stage liver disease(MELD)scores were calculated for each patient on admission.RESULTS:Compared with healthy controls,serum thymosinβ4 levels in ACLF,CLF,CR and chronic hepatitis B patients were significantly lower,6.5047 (4.7879-10.5314)μg/mL vs 0.4632(0.2759-0.8768) μg/mL,0.6981(0.5209-1.2008)μg/mL,1.8053 (0.8110-2.3397)μg/mL,3.7803(1.8570-6.4722)μg/mL, respectively(P<0.001).The levels of thymosinβ4 in liver failure(ACLF or CLF)patients were markedly lower than that in CR(P<0.001),and a difference was also found between CLF and ACLF patients(P=0.038).In patients with chronic liver disease,there was a positive relationship between thymosinβ4 levels and albumin, choline esterase,and platelet(P<0.001),and negative relationship with alanine aminotransferase(P=0.020), aspartate aminotransferase,total bilirubin,international normalized ratio of prothrombin time,and Child-Pugh and MELD scores(P<0.001).Of the 61 liver failure patients,the thymosinβ4 levels of non-survivors were significantly lower than that of survivors(P=0.007). Receiver operating characteristics analysis identified a thymosinβ4 cutoff level of 0.5708μg/mL for predicting poor prognosis in all liver failure patients.The serial thymosinβ4 values were observed in 13 liver failure inpatients.Lower initial values were observed in the death.While greater improvement in thymosinβ4 value was found in those who recovered from the disease. CONCLUSION:Serum thymosinβ4 can be used as an important potential predictor for liver failure caused by chronic HBV infection. | Tao Han,Ying Liu,Huan Liu,Zheng-Yan Zhu,Yan Li,Shi-Xiang Xiao,Zhen Guo,Zhen-Gang Zhao,Department of Hepatology,Tianjin Institute of Hepatobiliary Disease,Tianjin Key Laboratory of Artificial Cells,Tianjin Third Central Hospital,Tianjin Medical University,83 Jintang Road,Tianjin 300170, China | 2010 | World Journal of Gastroenterology2010，16，5： | 20 |
| 19 | High-intensity focused ultrasound treatment for patients with unresectable pancreatic cancer显示文摘BACKGROUND: High-intensity focused ultrasound (HIFU) is a non-invasive method of solid tissue ablation therapy. However, only a few studies have reported the effect of HIFU for unresectable pancreatic cancer. This study aimed to evaluate the clinical benefits, survival time and complications associated with the use of HIFU ablation in patients with unresectable pancreatic cancer. METHODS: Twenty-five patients with unresectable pancreatic cancer were enrolled in our study. All patients received HIFU therapy for tumors at least once. The therapeutic effects of HIFU was evaluated in terms of Karnofsky performance status (KPS) scores, pain relief, serum CA19-9, and imaging by B-US and CT before and after the therapy. We also recorded median overall survival time and complications caused by the treatment. RESULTS: In the 25 patients, KPS scores were above 60, and increased KPS was observed in 23 patients after treatment. Pain relief occurred in 23 patients. Serum CA19-9 levels were significantly reduced one month after HIFU treatment and became negative in 5 patients. B-US revealed enhanced tumor echogenicity in 13 patients and decreased tumor blood supply in 9. Tumor necrosis was confirmed by CT in 8 patients one month after HIFU treatment. The median overall survival time was 10 months, and the 1-year survival rate was 42%. No severe complications were observed after HIFU treatment. CONCLUSION: HIFU can effectively relieve pain, increase KPS, decrease tumor growth and prolong the survival time of patients with unresectable pancreatic cancer. | Peng-Zhou Li, Shai-Hong Zhu, Wei He, Li-Yong Zhu, Sheng-Ping Liu, Yan Liu, Guo-Hui Wang, Fei Ye Department of General Surgery ,Department of Radiology, Third Xiangya Hospital, Central South University, Changsha 410013, China | 2012 | Hepatobiliary & Pancreatic Diseases International2012，11，6： | 19 |
| 20 | Expression and significance of RhoC gene in hepatocellular carcinoma显示文摘AIM: To investigate the expression of RhoC gene inhepatocellular carcinoma (HCC) and to evaluate therelationship between RhoC gene expression and invasionand metastasis of HCC.METHODS: mRNA expression level of RhoC gene wasexamined by reverse transcription-polymerase chain reaction(RT-PCR) in 25 cases of HCC and para-cancerous normalliver tissues. In addition, mutation of RhoC gene wasexamined by polymerase chain reaction-single strandconformational polymorphism (PCR-SSCP).RESULTS: The mRNA expression levels of RhoC in tumortissues were significantly higher than those in para-cancerousnormal liver tissues (1.8±1.1 vs 1.0±0.7, P<0.01). Themetastatic lesions outside of liver also showed significantlyhigher RhoC mRNA levels than corresponding tumor tissuesin liver (3.3±0.5 vs2.0±0.7, P<0.01). There were significantassociations between RhoC gene expression and certainclinical and pathological findings, including celldifferentiation, vein invasion, number of tumor nodes andmetastatic lesions. Mutation of RhoC gene was not foundby PCR-SSCP.CONCLUSION: The RhoC gene may be related to malignanttransformation and development of HCC and may play animportant role in the invasion and metastasis of HCC byoverexpression but not mutation. | Wei Wang Lian-Yue Yang Zhi-Li Yang Gen-Wen Huang Wei-Qun Lu Liver Cancer laboratory,Department of General Surgery,Xiangya Hospital,Central South University,Changsha 410008,Hunan Province,China | 2003 | World Journal of Gastroenterology2003，9，9： | 19 |
