| 1 | Molecular mechanism about lymphogenous metastasis of hepatocarcinoma cells in mice显示文摘AIM To investigate the correlation between lymphogenous metastasis and matrix metalloproteinases (MMPs) activity and the expression of Fas Iigand of tumor cells in lymph nodes.METHODES Fifty-six inbred 615-mice were equally divided into 2 groups and inoculated with Hca-F and Hca-P cells. Their lymph node metastatic rates were examined.Growth fraction of lymphocytes in host lymph nodes was detected by flow cytometry. The Hca-F and Hca-P cells were cultured with extract of lymph node, liver or spleen.The quantity of MMPs in these supernatants was examined by zymographic analysis. The expression of Fas ligand,PCNA, Bcl-2 protein of Hca-F and Hca-P cells in the mice were examined by immunohistochemistry. The apoptosis signals of macrophages in lymph nodes were observed with in situ DNA fragmentation.RESULTS On the 28th day post-inoculation, the lymph node metastatic rate of Hca-F was 80% (16/20), whereas that of Hca-P was 25% (5/20). The growth fraction of lymphocytes was as follows: in the Hca-F cells, the proliferating peak of lymphocytes appeared on the 14th day post-inoculation and then decreased rapidly, while in HcaP cells, the peak appeared on the 7th day post-inoculation and then kept at a high level. With the extract of lymph node, the quantity of the MMP-9 activity increased (P<0.01) and active MMP-9 and MMP-2 were produced by both Hca-F and Hca-P tumor cells, which did not produce MMPs without the extract of lymph node or with the extracts of the liver and spleen. The expression of Fas Ligand of Hca-F cells was stronger than that of Hca-P cells (P<0.01). The expressions of PCNA and Bcl-2 protein of Hca-F cells in the tumors of inoculated area were the same as that of Hca-P cells. In situ DNA fragmentation showed that the positive signals of macrophages were around HcaF cells.CONCLUSION Secretion of MMPs which was associated with metastatic ability of Hca-F and Hca-P tumor cells depends on the environment of lymph nodes. The increased expression of Fas ligand protein of Hca-F tumor cells with high lymphogenous metastatic potential in lymph nodes may help tumor cells escape from being killed by host lymphocytes. | Li Hou Ying Li Yong-Hua Jia Bo Wang Yi Xin Mao-Ying Ling Shen Lü Department of Pathology,Dalian Medical University,Dalian 116027,Liaoning Province,ChinaDepartment of Biochemistry,Dalian Medical University,Dalian 116027,Liaoning Province,China | 2001 | World Journal of Gastroenterology2001,7,4: | 47 |

| 4 | Expressions of inducible nitric oxide synthase and matrix metalloproteinase-9 and their effects on angiogenesis and progression of hepatocellular carcinoma显示文摘AIM: To determine the expressions of inducible nitric oxide synthase (iNOS) and matrix metalloproteinase-9 (MMP-9)in hepatocellular carcinoma (HCC) and to investigate the relationship between iNOS and MMP-9 expression and their effects on angiogenesis and progression of HCC.METHODS: Tn this study, we examined iNOS, MMP-9,and CD34 expression in specimens surgically removed from 32 HCC patients and 7 normal liver tissues by immunohistochemical staining. Meanwhile, microvessel density (MVD) was determined as a marker of angiogenesis by counting CD34-positive cells.RESULTS: The positive rates of iNOS and MMP-9expression were 71.88% (23/32) and 78.13% (25/32) in HCC. MMP-g expression was significantly correlated with tumor size, capsule status, TNM stage, and risk of HCC recurrence (P= 0.032, P= 0.033, P= 0.007, and P= 0.001,respectively). There was also a significant relationship between iNOS expression and capsule status and risk of HCC recurrence (P = 0.04g and P = 0.004, respectively),but no correlation between iNOS expression and tumor size and TNM stage. There was a positive association between MVD and TNM stage and risk of HCC recurrence (P = 0.037 and P = 0.000, respectively). The count of MVD was significantly different in different iNOS and MMP-9 immunoreactivity groups (F= 17.713 and 17.097, P = 0.000 and P = 0.000, respectively). The examination of Spearman's rank correlation coefficient showed that there was a significant positive correlation between MVD and iNOS,MMP-9 immunoreactivity (r= 0.754 and 0.751, P= 0.000 and P=0.000, respectively). There was also a significant association between MMP-9 and iNOS expression in HCC (P = 0.010).CONCLUSION: Nitric oxide (NO) produced by iNOS could modulate MMP-9 production and therefore contribute to tumor cell angiogenesis and invasion and metastasis in HCC. The strong expression of iNOS and MMP-9 in HCC may be helpful in evaluating the recurrence of HCC,predicting poor prognosis. For patients with strong expression of MMP-9 and iNOS, the optimal treatment scheme needs to be selected. | Min-Hua Sun Xi-Chun Han Ming-Ku Jia Wei-Dong Jiang Min Wang Hong Zhang Gang Han Yi Jiang | 2005 | World Journal of Gastroenterology2005,11,38: | 30 |
| 5 | Efficacy and safety of a novel anti-HER2 therapeutic antibody RC48 in patients with HER2-overexpressing,locally advanced or metastatic gastric or gastroesophageal junction cancer:a single-arm phase II study显示文摘Background:Current treatment options for human epidermal growth factor receptor 2(HER2)-overexpressing gastric cancer at third-line have shown limited clinical benefit.Further,there is no specific treatment for HER2 immunohistochemistry(IHC)2+and fluorescence in-situ hybridization-negative patients.Here,we report the efficacy and safety of a novel anti-HER2 antibody RC48 for patients with HER2-overexpressing,advanced gastric or gastroesophageal junction cancer.Methods:Patients with HER2-overexpressing(IHC 2+or 3+),locally advanced or metastatic gastric or gastroesophageal junction cancer who were under at least second-line therapy were eligible and received RC482.5 mg/kg alone every 2 weeks.The primary endpoint was the objective response rate(ORR)assessed by an independent review committee.Secondary endpoints included progressionfree survival(PFS),overall survival(OS),duration of response,time to progression,disease control rate,and safety.Results:Of 179 patients screened,125 were eligible and received RC48 treatment.The ORR was 24.8%(95%confidence interval[CI]:17.5%-33.3%).The median PFS and OS were 4.1 months(95%CI:3.7-4.9 months)and 7.9 months(95%CI:6.7-9.9 months),respectively.The most frequently reported adverse events were decreased white blood cell count(53.6%),asthenia(53.6%),hair loss(53.6%),decreased neutrophil count(52.0%),anemia(49.6%),and increased aspartate aminotransferase level(43.2%).Serious adverse events(SAEs)occurred in 45(36.0%)patients,and RC48-related SAEs were mainly decreased neutrophil count(3.2%).Seven patients had adverse events that led to death were not RC48-related.Conclusions:RC48 showed promising activity with manageable safety,suggesting potential application in patients with HER2-overexpressing,advanced gastric or gastroesophageal junction cancer who have previously received at least two lines of chemotherapy. | Zhi Peng Tianshu Liu Jia Wei Airong Wang Yifu He Liuzhong Yang Xizhi Zhang Nanfeng Fan Suxia Luo Zhen Li Kangsheng Gu Jianwei Lu Jianming Xu Qingxia Fan Ruihua Xu Liangming Zhang Enxiao Li Yuping Sun Guohua Yu Chunmei Bai Yong Liu Jiangzheng Zeng Jieer Ying Xinjun Liang Nong Xu Chao Gao Yongqian Shu Dong Ma Guanghai Dai Shengmian Li Ting Deng Yuehong Cui Jianmin Fang Yi Ba Lin Shen | 2021 | Cancer Communications2021,41,11: | 29 |
| 6 | Prevalence of Thyroid Nodules and Its Relationship with Iodine Status in Shanghai:a Population-based Study显示文摘Objective This study was designed to evaluate the prevalence of thyroid nodules(TNs) and its relationship with urine iodine concentrations(UICs) after the regional rapid economic growth and lifestyle changes. Methods A cross-sectional survey was conducted in the general population aged 15-69 years. A questionnaire regarding general and personal characteristics and relevant information was administered. Ultrasonography of the thyroid was performed, and serum triiodothyronine(T3), tetraiodothyronine(T4), serum thyroid stimulating hormone(TSH), free triiodothyronine(FT3), free tetraiodothyronine(FT4), thyroglobulin antibody(Tg Ab), thyroid peroxidase antibody(TPOAb), and TSH receptor antibody(TRAb) levels were measured for each individual subject. Results The prevalence rates of TNs in the whole population, females and males were 27.76%, 34.04%, and 21.60%, respectively. The prevalence of multiple nodules increased with age, whereas the prevalence peaks differed between males and females. The median UICs in the whole population and females with non-TNs were higher than those of subjects with TNs(P=0.0035, P=0.0068). The median UICs in subjects with a single TN were higher than those in subjects with multiple TNs(P=0.0164, P=0.0127). The result showed a U-shaped curve relationship between UIC and prevalence of TNs. The prevalence of TNs was the lowest when the UIC was 140-400 μg/L. Conclusion The prevalence of TNs was nearly 30% and increased with age. The relationship between UIC and prevalence of TNs is U-shaped, with an increase in risk when the UIC was <140 μg/L and >400 μg/L. Very low or high UIC levels need attention and correction. | SONG Jun ZOU Shu Rong GUO Chang Yi ZANG Jia Jie ZHU Zhen Ni MI Ming HUANG Cui Hua YU Hui Ting LU Xi RUAN Ye WU Fan | 2016 | Biomedical and Environmental Sciences2016,29,6: | 25 |
| 7 | Extrahepatic portacaval shunt via a magnetic compression technique: A cadaveric feasibility study显示文摘AIM: To explore the anatomical feasibility of portacaval shunt using a magnetic compression technique(MCT) in cadavers.METHODS: Computed tomography(CT) images of 30 portal hypertensive patients were obtained.The diameters of the portal vein(PV),the inferior vena cava(IVC),and distance between the two structures were measured.Similar measurements were performed on 20 adult corpses.The feasibility of portacaval shunt based on those measurements was analyzed.First stage of the extrahepatic portacaval shunt using MCT was performed on five cadavers.Specifically,the PV and IVC were exposed through an abdominal incision of the cadavers.The parent magnet was introduced from the femoral vein and was delivered into the IVC by an anchor wire and a 5F Cook catheter.The daughter magnet was introduced into the PV through the splenic vein using aninterventional guide wire.When the daughter magnet met the parent magnet,they automatically clipped together and the first stage of the portacaval shunt was set up.RESULTS: The average diameters of the PV and the IVC measured from the 30 CT image were 14.39 ± 2.36 mm and 18.59 ± 4.97 mm,respectively,and the maximum and minimum distances between the PV and the IVC were 9.79 ± 4.56 mm and 9.50 ± 4.79 mm,respectively.From 20 cadavers,the average diameters of the PV and the IVC were 14.48 ± 1.47 mm and 24.71 ± 2.64 mm,and the maximum and minimum distances between the PV and the IVC were 10.14 ± 1.70 mm and 8.93 ± 1.17 mm,respectively.The distances between the PV and the IVC from both the CT images and the cadavers were within the effective length of portacaval anastomosis using MCT(30.30 ± 4.19 mm).The PV and IVC are in close proximity to each other with no intervening tissues or structures in between.Simulated surgeries of the first stage using MCT on five cadavers was successfully performed.CONCLUSION: Anatomically,extrahepatic portacaval shunt employing MCT is highly feasible in humans. | Xiao-Peng Yan Wen-Yan Liu Jia Ma Jian-Peng Li Yi Lv | 2015 | World Journal of Gastroenterology2015,21,26: | 24 |

| 9 | Chemical Constituents from Leaves of Camellia nitidissima and Their Potential Cytotoxicity on SGC7901 Cells显示文摘Objective To isolate and identify the bioactive phytochemicals from the leaves of Camellia nitidissima. Methods The chemical constituents were isolated and purified by repeated silica gel, Sephadex LH-20, MCI gel columns, recrystallization, and semi-preparative HPLC techniques. The chemicl structures of these compounds were identified on the basis of spectral data including NMR and MS. Then quorum sensing inhibition(QSI) activities of these compounds were tested using Chromobacterium violaceum CV026 as the bioindicator strain. The antitumor activities of these compounds were measured using SGC7901 as cell proliferation and cytotoxicity. Resultsα-Spinasteryl-β-D-glucopyranoside(1), stigmasta-7,22-diene-3-O-[α-L-arabinopyranosyl(1→2)]-β-D-galactopyranoside(2), kaempferol 3-O-[2-O-(trans-p-coumaroyl)-3-O-α-D-glucopyranosyl]-α-D-glucopyranoside(3), aromadendrin(4), catechin(5), phlorizin 4′-O-β-D-glucopyranoside(6),(3R,6R,7E)-3-hydroxy-4,7-megastigmadien-9-one(7), dodecanoic acid(8), 3β-acetoxy-20-lupanol(9), and 3β,6α,13β-trihydroxyolean- 7-one(10) were successively isolated from the leaves of C. nitidissima. Unfortunately, these compounds had no QSI activity. Based on Cell Counting Kit-8(CCK-8) assay, compound 10 showed the best anti-tumor activity of all compounds(IC50 = 91.7 μg/m L). Conclusion Apart from compounds 4 and 5, other eight compounds are reported in this plant for the first time. All compounds show no QSI activity, compound 10 shows potential cytotoxic activity on SGC7901 cells in vitro. | Jing Qi Ruo-fu Shi Jian-ming Yu Yi Li Sheng-tao Yuan Ji-zhu Yang Jiang-miao Hu Ai-qun Jia | 2016 | Chinese Herbal Medicines2016,8,1: | 23 |

| 13 | Catalytic oxidation of benzene over Ce-Mn oxides synthesized by flame spray pyrolysis显示文摘Flame spray pyrolysis(FSP) was utilized to synthesize Ce-Mn oxides in one step for catalytic oxidation of benzene.Cerium acetate and manganese acetate were used as precursors.The materials synthesized were characterized using X-ray diffraction(XRD),N_2 adsorption,X-ray photoelectron spectroscopy(XPS).transmission electron microscopy(TEM),Raman spectroscopy,and Fh-temperature programmed reduction(H_2-TPR) and their benzene catalytic oxidation behavior was evaluated.Mn ions were evidenced in multiple chemical states.Crystalline Ce-Mn oxides consist of particles with size <40 nm and specific surface areas(SSA) of 20-50m^2/g.Raman spectrums and H_2-TPR results indicated the interaction between cerium and manganese oxides.Flame-made 12.5%-Ce-Mn oxide exhibited excellent catalytic activity at relatively low temperatures(T95 about 260 C) compared to other Ce-Mn oxides with different ceriumto-manganese ratios.Redox mechanism and strong interaction conform to structure analysis that Ce-Mn strong interaction formed during the high temperature flame process and the results were used to explain catalytic oxidation of benzene. | Gang Liu Renliang Yue Yi Jia Yong Ni Jie Yang Haidi Liu Zhen Wang Xiaofeng Wu Yunfa Chen | 2013 | Particuology2013,11,4: | 17 |
| 14 | Fine mapping and marker-assisted selection (MAS) of a low glutelin content gene in rice显示文摘Rice with low glutelin content is suitable as functional food for patients affected with diabetes and kidney failure. The fine mapping of the gene(s) responsible for low glutelin content will provide information regarding the distribution of glutelin related genes in rice genome and will generate markers for the selection of low glutelin rice varieties. Following an SDS-PAGE screen of rice germplasm from Taihu Valley of China, Japonica selection W3660 is identified to be a novel mutant characterized with low glutelin content. For fine mapping the mutant gene for low glutelin content, F2 and F3 populations were derived from a cross between W3660 and Jingrennuo. SDS-PAGE analysis of the total endosperm protein showed that the low glutelin content trait was controlled by a single dominant nuclear gene. Genetic mapping, using SSRs, located this gene to chromosome 2, in the region between SSR2-001/SSR2-004 and RM1358. The dis- tances of the two markers to the target gene were 1.1 cM and 3.8 cM respectively. By semi-quantitative RT-PCR analysis, the transcripts of GluB4/GluB5 genes located within the region do not change. However, GluB5 gene located proximal to SSR2-001/SSR2-004 was specifically reduced. SSR profiles of seven Japonica varieties were compared with that of W3660 for loci in the relevant genetic region. The markers SSR2-004 and RM1358 were used for marker- assisted selection. The selection efficiencies of SSR2-004 and RM1358 were 96.8% and 92.7% respectively. This provides a standard starting point for the breeding of low glutelin content rice varieties in China. | Yi Hua WANG Shi Jia LIU Su Lan JI Wen Wei ZHANG Chun Ming WANG Ling JIANG Jian Min WAN | 2005 | Cell Research2005,15,8: | 16 |
| 15 | The emergence of pandemic influenza viruses显示文摘Pandemic influenza has posed an increasing threat to public health worldwide in the last decade.In the 20th century,three human pandemic influenza outbreaks occurred in 1918,1957 and 1968,causing significant mortality.A number of hypotheses have been proposed for the emergence and development of pandemic viruses,including direct introduction into humans from an avian origin and reassortment between avian and previously circulating human viruses,either directly in humans or via an intermediate mammalian host.However,the evolutionary history of the pandemic viruses has been controversial,largely due to the lack of background genetic information and rigorous phylogenetic analyses.The pandemic that emerged in early April 2009 in North America provides a unique opportunity to investigate its emergence and development both in human and animal aspects.Recent genetic analyses of data accumulated through long-term influenza surveillance provided insights into the emergence of this novel pandemic virus.In this review,we summarise the recent literature that describes the evolutionary pathway of the pandemic viruses.We also discuss the implications of these findings on the early detection and control of future pandemics. | Yi Guan Dhanasekaran Vijaykrishna Justin Bahl Huachen Zhu Jia Wang Gavin J.D.Smith | 2010 | Protein & Cell2010,1,1: | 16 |
