| 1 | Recurrence or metastasis of HCC:predictors,early detection and experimental antiangiogenic therapy显示文摘AIM To investigate the predictors forrecurrence or metastasis of HCC,and toevaluate the effect of antiangiogenic therapy onthe growth of transplantable human HCC in nudemice.METHODS RT-PCR was used to measure theexpression of matrix metalloproteinase-9(MMP-9)and vascular endothelial growth factor(VEGF)in 56 pairs of nontumorous liver andtumor samples.Sixty blood samples from humanHCC were examined by nested RT-PCR to find outAFP mRNA.Recombinant human endostatin andpolyclonal antibody against VEGF wereadministered to treat human HCC transplanted innude mice.RESULTS Thirty of 56 HCC samples showedstronger expression of MMP-9 in tumoroustissues than in nontumorous tissues.Fifteen ofthe 26 patients with relative expression level ofMMP-9 more than 0.34 developed tumorrecurrence or metastasis,whereas only 7 of 30patients with relative expression level less than0.34 developed tumor recurrence(P<0.05).There was no significant difference in therelative expression level of VEGF betweenpatients with postoperative recurrence ormetastasis and those without recurrence.AFPmRNA was detectable in 53.3% of patients withHCC.The sensitivity and specificity of AFPmRNA as a marker to detect hematogenousdissemination of HCC cells was 81.8% and84.4%,respectively.Recombinant human endostatin and polyclonal antibody against VEGFinhibited the growth of transplantable HCC innude mice by 52.2% and 45.7%,respectively.CONCLUSION MMP-9 expression in HCCcorrelates with the postoperative recurrence ormetastasis of HCC.Patients with high level ofMMP-9 expression in HCC are susceptible tometastasis.AFP mRNA could serve as anindicator of hematogenous spreading of HCCcells in circulation and a predictor of recurrenceor metastasis of HCC.Antiangiogenesis may bean adjuvant therapy for HCC. | Jiang YF Yang ZH Hu JQ | 2000 | World Journal of Gastroenterology2000，6，1： | 57 |

| 5 | 槲皮素对前列腺癌细胞增殖及转录因子Sp1功能的抑制作用显示文摘雄激素受体(androgenreceptor,AR)作为核转录因子,其高表达、基因突变以及AR辅激活因子的过表达等造成AR的异常激活与前列腺癌细胞的增殖、恶化转移、多药耐药等密切相关.天然黄酮槲皮素(quercetin),是一很有潜力的预防和治疗前列腺肿瘤的化合物.槲皮素不仅抑制前列腺癌细胞LNCaP的增殖,并呈剂量依赖性,而且下调前列腺癌中AR的表达、抑制AR的转录激活功能.GCbox是AR核心启动子的主要正调控元件,是转录因子Sp1的结合位点.细胞转染结果表明,槲皮素能抑制Sp1蛋白对AR启动子的激活作用,可能是槲皮素下调AR表达的机理之一.进一步研究显示,槲皮素还能明显抑制Sp1蛋白对AR转录激活功能的增强作用.Western印迹结果显示,槲皮素对Sp1蛋白表达无明显影响,但能够诱导c-Jun的高表达,而高表达的c-Jun蛋白能逆转Sp1蛋白对AR的转录激活作用,由此推测,槲皮素可能通过介导c-Jun与Sp1的蛋白质相互作用,抑制Sp1的功能,进而起到抑制AR表达和功能的作用.免疫沉淀结果又进一步证实了Sp1与c-Jun二者的相互作用.因此,槲皮素可能通过抑制前列腺癌细胞中AR的表达和功能抑制了细胞的增殖,其分子机理可能与槲皮素诱导的c-Jun与Sp1蛋白相互作用、降低Sp1对AR的转录激活作用有关. | 苑辉卿 杨玲玲 姜安丽 孔峰 张建业 Charles YF YOUNG | 2005 | 中国生物化学与分子生物学报2005，21，5： | 21 |

| 13 | c-Jun和CBP在槲皮素抑制前列腺癌中的作用显示文摘目的探讨槲皮素抑制前列腺癌的作用机制。方法应用蛋白印迹技术检查槲皮素(quercetin)对雄激素受体(androgen receptor,AR)的辅调节因子c-Jun和cAMP应答元件结合蛋白的结合蛋白[cAMP response elem entb ind ing prote in(CREB)-b ind ing prote in,CBP]蛋白表达的影响;利用细胞转染技术检测c-Jun和CBP对AR功能的影响;免疫沉淀技术检验c-Jun与AR的蛋白-蛋白相互作用。结果槲皮素能够明显诱导c-Jun的高表达,高表达的c-Jun能够抑制AR的功能。槲皮素对CBP的蛋白表达水平无明显影响,而增加CBP的表达并不能逆转槲皮素对AR功能的抑制作用。免疫沉淀结果表明,c-Jun与AR存在蛋白-蛋白相互作用。结论槲皮素抑制前列腺癌的机制可能是通过c-Jun与AR的蛋白相互作用,而不是通过c-Jun竞争结合AR的辅激活因子CBP来实现的。 | 苑辉卿 郭怀芳 贺美兰 孔峰 胡晓燕 姜安丽 徐霞 张建业 Charles YF Young | 2006 | 药学学报2006，41，9： | 9 |
| 14 | 小胶质细胞对星形胶质细胞的免疫和神经保护功能的调节作用(英文)显示文摘在中枢神经系统中,小胶质细胞和星形胶质细胞对神经元的发育、功能维持及细胞存活具有重要的作用。但在炎症反应过程中,星形胶质细胞增生的作用及其对神经元的影响目前并不十分清楚。因此,本研究对不同种类的细胞进行培养,给予细菌脂多糖(lipopolysaccharide,LPS)刺激,观察各种细胞的反应。结果显示,星形胶质细胞可以减轻炎症反应的神经元毒性,提示星形胶质细胞增生主要具有神经保护作用。如果去掉上清液中由星形胶质细胞分泌的胶质细胞源性神经营养因子(glial cell line-derived neurotrophic factor,GDNF),这种神经保护作用显著降低。为了研究星形胶质细胞的免疫功能,本研究培养了高浓度的星形胶质细胞,并发现LPS不能诱导肿瘤坏死因子(tumor necrosis factor,TNF)-α及诱导型一氧化氮合酶(inducible nitric oxide synthase,iN OS)/一氧化氮(nitric oxide,NO)(iN OS/NO)释放。但如果在培养的高浓度星形胶质细胞中增加0.5%~1%的小胶质细胞,则可以诱导TNF-α及iN OS/NO的释放。这提示小胶质细胞和星形胶质细胞间的相互作用对于LPS诱导星形胶质细胞释放前炎症因子及GDNF是必须的。我们还发现,小胶质细胞释放的TNF-α可以通过旁分泌作用调节星形胶质细胞的神经保护功能。综上所述,本研究结果提示星形胶质细胞可能不会直接被LPS激活,而是通过与小胶质细胞相互作用被激活,释放神经营养因子,减少因炎症反应激活的小胶质细胞释放的毒性物质对神经元的损害作用。 | Chen SH Oyarzabal EA Sung YF Chu CH Wang Q Chen SL Lu RB Hong JS 唐颖馨 | 2015 | 神经损伤与功能重建2015，10，1： | 9 |
| 15 | Expression of gap junction genes connexin 32,connexin 43 and their proteins in hepatocellular carcinoma and normal liver tissues显示文摘AIM To investigate the significance andmechanism of cx32 mRNA,cx43 mRNA and theirproteins in hepatocarcinogenesis.METHODS Sixty-one cases of HCC and 14cases of normal liver tissues were detected byimmunohistochemical and in situ hybridization(ISH)methods.RESULTS In HCC grades Ⅰ,Ⅱ,Ⅲ and normalliver tissues,the positive rates of Cx32 proteinwere 55.6%,42.1%,18.2% and 92.9%,respectively.The detection rates of Cx43 proteinwere 44.4%,26.3%,12.1% and 78.6%,respectively.There was significant difference inCx32 and Cx43 protein between HCC and normalliver tissues(P<0.01).ISH the positive rates ofcx32 mRNA shown by ISH in HCC grades Ⅰ,Ⅱ,Ⅲ and normal liver tissues were 88.9%,84.2%,87.9% and 92.9%,respectively.Those of cx43mRNA were 77.8%,78.6%,78.8% and 85.7%,respectively.There was no statistical differencein the positive rates of cx32 mRNA and cx43mRNA between HCC and normal liver tissue(P>0.05).CONCLUSION The aberrant location of Cx32and Cx43 proteins could be responsible forprogression of hepatocarcinogenesis,and thedefect of cx genes in post-translationalprocessing might be the possible mechanism. | Ma XD Sui YF Wang WL | 2000 | World Journal of Gastroenterology2000，6，1： | 9 |
| 16 | Differences in neuroplasticity after spinal cord injury in varying animal models and humans显示文摘Rats have been the primary model to study the process and underlying mechanisms of recovery after spinal cord injury. Two weeks after a severe spinal cord contusion, rats can regain weight-bearing abilities without therapeutic interventions, as assessed by the Basso, Beattie and Bresnahan locomotor scale. However, many human patients suffer from permanent loss of motor function following spinal cord injury. While rats are the most understood animal model, major differences in sensorimotor pathways between quadrupeds and bipeds need to be considered. Understanding the major differences between the sensorimotor pathways of rats, non-human primates, and humans is a start to improving targets for treatments of human spinal cord injury. This review will discuss the neuroplasticity of the brain and spinal cord after spinal cord injury in rats, non-human primates, and humans. A brief overview of emerging interventions to induce plasticity in humans with spinal cord injury will also be discussed. | Mallory E.Filipp Benjamin J.Travis Stefanie S.Henry Emma C.Idzikowski Sarah A.Magnuson Megan YF Loh Daniel J.Hellenbrand Amgad S.Hanna | 2019 | Neural Regeneration Research2019，14，1： | 8 |

| 20 | Lean techniques for the improvement of patients' flow in emergency department显示文摘BACKGROUND: Emergency departments(EDs) face problems with overcrowding, access block, cost containment, and increasing demand from patients. In order to resolve these problems, there is rising interest to an approach called 'lean' management. This study aims to(1) evaluate the current patient flow in ED,(2) to identify and eliminate the non-valued added process, and(3) to modify the existing process.METHODS: It was a quantitative, pre- and post-lean design study with a series of lean management work implemented to improve the admission and blood result waiting time. These included structured re-design process, priority admission triage(PAT) program, enhanced communication with medical department, and use of new high sensitivity troponin-T(hsTnT) blood test. Triage waiting time, consultation waiting time, blood result time, admission waiting time, total processing time and ED length of stay were compared.RESULTS: Among all the processes carried out in ED, the most time consuming processes were to wait for an admission bed(38.24 minutes; SD 66.35) and blood testing result(mean 52.73 minutes, SD 24.03). The triage waiting time and end waiting time for consultation were significantly decreased. The admission waiting time of emergency medical ward(EMW) was significantly decreased from 54.76 minutes to 24.45 minutes after implementation of PAT program(P<0.05).CONCLUSION: The application of lean management can improve the patient flow in ED. Acquiescence to the principle of lean is crucial to enhance high quality emergency care and patient satisfaction. | HY Chan SM Lo LLY Lee WYL Lo WC Yu YF Wu ST Ho RSD Yeung JTS Chan | 2014 | World Journal of Emergency Medicine2014，5，1： | 6 |
