| 1 | Inhibiting effect of antisense oligonucleotides phosphorthioate on gene expression of TIMP-1 in rat liver fibrosis显示文摘AIM To observe the inhibition of antisenseoligonucleotides (asON) phosphorthioate to thetissue inhibitors metalloproteinase-1 (TIMP-1)gene and protein expression in the liver tissue ofimmunologically induced hepatic fibrosis rats.The possibility of reversing hepatic fibrosisthrough gene therapy was observed.METHODS Human serum albumin (HSA) wasused to attack rats, as hepatic fibrosis model, inwhich asONs were used to block the gene andprotein expressing TIMP-1. According to theanalysis of modulator, structure protein, codingseries of TIMP-1 genome, we designed fourdifferent asONs. These asONs were injected intothe hepatic fibrosis models through coccygealvein. The results was observed by RT-PCR formeasuring TIMP-1 mRNA expression,immunohistochemistry and in situ hybridizationfor collagen Ⅰ, Ⅲ, special staining of collagenfiber, and electron microscopic examination.RESULTS Hepatic fibrosis could last within 363days in our modified model. The expressinglevel of TIMP-1 was high during hepatic fibrosisprocess. It has been proved by theimmunohistochemical and the electronmicroscopic examination that the asONphosphorthioate of TIMP-1 could exactly expressin vivo. The effect of colchicine wasdemonstrated to inhibit the expressing level ofmRNA and the content of collagen Ⅰ, Ⅲ in theliver of experimental hepatic fibrosis rats.However, the electron microscopy research andthe pathologic grading of hepatic fibrosisshowed that there was no significant differencebetween the treatment group and the modelgroup (P>0.05).CONCLUSION The experimental rat model ofhepatic fibrosis is one of the preferable modelsto estimate the curative effect of anti-hepaticfibrosis drugs. The asON phosphorthioate ofTIMP-1 could block the gene and proteinexpression of TIMP-1 in the liver of experimentalhepatic fibrosis rats at the mRNA level. It ispossible to reverse hepatic fibrosis, and it isexpected to study a new drug of anti-hepaticfibrosis on the genetic level. Colchicine has verylimited therapeutic effect on hepatic fibrosis,furthermore, its toxicity and side effects areobvious. | Qing He Nie Yong Qian Cheng Yu Mei Xie Yong Xing Zhou Yi Zhan Cao The Center of Infectious Disease Diagnosis and Treatment of PLA,Tangdu Hospital,Forth Military Medical University,Xi’an 710038,Shaanxi Province,ChinaDr,Qing He Nie graduated from Qinghai Medical College as a doctor in 1983,got master degree at Beijing 302 Army Hospital in 1993,got doctor degree at the Third Military Medical University in 1998,engaged in postdoctoral research at the Fourth Military Medical University from 1998 to 2000,now an associate professor,specialized in clinical and experimental research of infectious diseases,had more than 90 papers published,coauthor of ten books,first author of one book. | 2001 | World Journal of Gastroenterology2001，7，3： | 73 |

| 4 | Evolving concepts in bone infection: redefining “biofilm”,“acute vs. chronic osteomyelitis”, “the immune proteome” and “local antibiotic therapy”显示文摘Osteomyelitis is a devastating disease caused by microbial infection of bone. While the frequency of infection following elective orthopedic surgery is low, rates of reinfection are disturbingly high. Staphylococcus aureus is responsible for the majority of chronic osteomyelitis cases and is often considered to be incurable due to bacterial persistence deep within bone. Unfortunately, there is no consensus on clinical classifications of osteomyelitis and the ensuing treatment algorithm. Given the high patient morbidity,mortality, and economic burden caused by osteomyelitis, it is important to elucidate mechanisms of bone infection to inform novel strategies for prevention and curative treatment. Recent discoveries in this field have identified three distinct reservoirs of bacterial biofilm including: Staphylococcal abscess communities in the local soft tissue and bone marrow, glycocalyx formation on implant hardware and necrotic tissue, and colonization of the osteocyte-lacuno canalicular network(OLCN) of cortical bone. In contrast, S.aureus intracellular persistence in bone cells has not been substantiated in vivo, which challenges this mode of chronic osteomyelitis. There have also been major advances in our understanding of the immune proteome against S. aureus, from clinical studies of serum antibodies and media enriched for newly synthesized antibodies(MENSA), which may provide new opportunities for osteomyelitis diagnosis, prognosis, and vaccine development. Finally, novel therapies such as antimicrobial implant coatings and antibiotic impregnated 3D-printed scaffolds represent promising strategies for preventing and managing this devastating disease. Here, we review these recent advances and highlight translational opportunities towards a cure. | Elysia A. Masters Ryan P.

| 5 | Orthotopic transplantation model of human gastrointestinal cancer and detection of micrometastases显示文摘AIM To establish a relevant animal model ofhuman gastrointestinal cancer, which can beused for repetitive investigations, so as toimprove our understanding and management ofcarcinogenesis and cancer metastasis.METHODS Intact tissues of human colorectaland pancreatic cancers were transplanted innude mice. The biological characteristics of theoriginal and the corresponding transplantedtumors were investigated by HE staining, PASstaining and immunostaining. The metastases inthe livers and lungs of nude mice wereinvestigated by immunostaining withbiotinylated mab KL-1 and by RT-PCR using CK20specific primers.RESULTS There were totally 9 of 16 surgicalspecimens growing in nude mice subcutaneouslyand/.or orthotopically (4 of 6 colorectal and 5 of10 pancreatic cancer). Tumor cell content of thespecimens and freezing of tissue specimens areimportant factors influencing the growth oftransplanted tumor. In the group of fresh tumortissues with greater than 50% tumor cellcontent, the success rate of the transplantationwas 100% (3 cases of pancreatic cancer and 3cases of colorectal cancer). The orthotopicallytransplanted tumors resemble the original tumormorphologically and biologically, including TAAexpression such as CEA byimmunohistochemistry, and CEA level in theserum of mice. Ki-67 labeling index and theexpression of TAA especially K-ras, 17-lA andRA-96, are associated with the potential of tumorgrowth in nude mice. Micrometastases in thelungs and livers of tumor bearing mice can bedetected by immunostaining with biotinylatedmab KL-1 and CK20-specific RT-PCR.CONCLUSION An orthotopic transplantationmodel for human colon and pancreatic cancer innude mice has been set up. We have alsoestablished sensitive detection methods withCK-immunohistochemistry and CK20-RT-PCR tostudy xenotransplanted human cancer and itsmetastatic cancer cells in the liver and lung ofnude mice. This study may be helpful inunderstanding the mechanism of cancermetastasis and in developing new diagnosticmethods and therapeutic strategies formetastases including micrometastases. | Jun Hui Cui~1 Uwe Krueger~2 Doris Henne-Bruns~2 Bemd Kremer~2 Holger Kalthoff~2 ~1Department of General Surgery,First Affiliated Hospital,College of Medicine,Zhejiang University,Hangzhou 310003,Zhejiang Province,China ~2Department of General Surgery,Christian-Albrechts-University,Kiel,GermanyDr.Jun Hui Cui graduated from Zhejiang Medical University in 1984,earned master degree in 1990,studied in the Surgical Department of Kiel University and worked in the Lab of Molecular Oncology of Kiel University from 1994-1997achieved M.D.from Kiel University.Germany,now associate professor of surgery,specialized in colorectal oncology.Adviser of graduated student for master degree,having 20 publications published in key Chinese or English journals. | 2001 | World Journal of Gastroenterology2001，7，3： | 19 |
| 6 | Effect of arsenic trioxide on rat hepatocarcinoma and its renal cytotoxicity显示文摘AIM: To study the effect of arsenic trioxide (As2O3) on rat experimental hepatocarcinoma and its renal cytotoxicity.METHODS: The hepatocarcinoma model was established by diethaylnitrosamine perfusion in stomach of 120 Wistar rats, and the treatment began at the end of 20 weeks.Before the treatment, the rat models were randomly divided into 5 groups. In the treatment groups, three doses of As2O3 were injected into rat abdominal cavity, the total time of drug administration was 4 weeks. Cisplatin control or the blank group was injected into abdominal cavity with equal amount of cisplatin or saline at the same time,respectively. On the 7th, 14th and 28th day after the treatment, the hepatocarcinoma nodules were obtained and the morphologic changes of hepatocarcinoma cells were observed under light and electron microscopes;Immunohistochemistry (S-P methods) was employed to detect the expression of bcl-2, bax and PCNA in hepatocarcinoma tissues; flow cytometry (TUNEL assay)was used to detect the apoptosis of liver cancer cells and the change of cytokinetics. On the 28th day, the kidneys were obtained and their histologic changes were observed under light microscope, and immunohistochemistry (SP stain) was also employed to detect the expression of bcl-2and PCNA. Cisplatin and saline solution were used as the control.RESULTS: As2O3 could induce the apoptosis of rat liver cancer cells and exhibited typical morphologic changes.The incidence of apoptosis of hapatocarcinoma cells was elevated (P=0.001). The elevation was the most higher in the group of middle-dose of As2O3 (1 mg.kg-1), significantly higher than that of the other arsenic groups and the controls (P=0.001). Large dose of As2O3 (5 mg.kg-1) was able to arise the incidence of apoptosis, but also produced a large amount of necrosis and inflammatory reaction. Middle dose of As2O3 dramatically increased the cell number in G2/M phase (P=0.0001), and apoptosis happened apparently.The expression of bcl-2 and bax was related to the dose of As2O3. With the up-regulation of apoptotic incidence, the ratio of bcl-2/bak decreased. But the incidence of apoptosis was not the highest status and the ratio of bcl-2/bax was at the lowest when the highest-dose of As2O3 was used.There was significant difference among the PCNA indexes (PCNA L1) of the five groups. Of them, three arsenic groups all showed decrease of different degrees, and this downregulation was most obvious in group A. There was significant difference among the three groups (P=0.016).Under the light microscope, the rat kidney in the cisplatin group exhibited tubular epithelium swelling and degeneration, protein casts in collecting tubules; While all arsenic groups didn't show the significant changes (P=0.013).In the arsenic groups, the expression of bcl-2 in the renal tubular epithelium was increased (P=0.005), no obvious changes happened to PCNA L1. But in the group of cisplatin,the PCNA L1 increased significantly (P=0.001).CONCLUSION: AS2O3 can induce apoptosis of rat hepatocellular carcinoma cells. And there is optimum dose;too high dose will induce the cytotoxic effect, while certain dose of As2O3 is able to block the cell cycle at G2/M phase.As2O3 had the most remarkable influence on G2/M cells,and it can also induce apoptosis to cells at other phases.As2O3 can restrain the proliferation of rat hepatocellular carcinoma cells, in a dose-time dependent manner.Compared with cisplatin, As2O3 didn't show obvious renal toxicity, which was related to the increasing expression of bcl-2 in renal tubular epithelium, the inhibition of apoptosis and the anti-oxidation effects. | Shao-Shan Wang Ti Zhang Xi-Lu Wang Li Hong Department of Surgery of Dagang Hospital 300270,Tianjin,China Qing-Hui Qi Department of Chinese and Western Integral Surgery of Master Hospital of Tianjin Medical University 300052,Tianjin,China | 2003 | World Journal of Gastroenterology2003，9，5： | 17 |

| 11 | NUMERICAL ANALYSIS OF THE MECHANICS OF SOIL REINFORCEMENT显示文摘Roots affect the soil stress and strain and contribute to soil reinforcement. An analysis of stress and strain in the root-soil composite is presented which combines roots, soils, and an interface element by using the Duncan-Chang E- model and a nonlinear-interface-element model. In this research, a finite element numerical analysis method was applied to simulate the stress field resulting in a composite of Pinus tabulaeformis roots and soils. Results show that roots can transmit the stress from surface soils to deep soils, and can reduce soil stress within the surface soil layer; results also show that the effect of soil reinforcement by roots is limited to surface soils. The Slope Safety Index of a pine slope becomes 10% higher than that of a natural slope, indicating that roots have a significant effect on soil reinforcement. | Weifeng SONG1, Lihua CHEN2 and Xiuping LIU3 1 PhD candidate, senior engineer, College of Water and Soil Conservation, Beijing Forestry University Key Laboratory of Soil and Water Conservation and Combating Desertification, Ministry of Education, Beijing 100083, China 2 Prof., Doctor, College of Water and Soil Conservation, Beijing Forestry University Key Laboratory of Soil and Water Conservation and Combating Desertification, Ministry of Education, Beijing 100083, China 3 Master, College of Water and Soil Conservation, Beijing Forestry University Key Laboratory of Soil and Water Conservation and Combating Desertification, Ministry of Education, Beijing 100083, China | 2006 | International Journal of Sediment Research2006，21，3： | 9 |

| 17 | 藏药七十味珍珠丸对阿尔茨海默病转基因Tg2576鼠认知能力及脑羧基末端片段蛋白含量的影响显示文摘目的探讨藏药七十味珍珠丸(ratanasampil,RNSP)对阿尔茨海默病(AD)模型鼠的学习和记忆功能、认知能力以及脑β淀粉样前体蛋白(amyloid precursor protein,APP)和羧基末端片段(C-terminal fragment,CTF)蛋白含量的影响。方法应用Y-迷宫明暗分辨学习和旷场实验观察13~14月龄雌性Tg2576转基因鼠和同龄雌性BL6/SJL非转基因(NTg)鼠的学习、记忆功能和行为学的变化。治疗组选取7只Tg2576鼠和5只NTg鼠用被溶解的RNSP灌胃8周,对照组选取8只Tg2576鼠和5只NTg鼠用蒸馏水和芝麻油混匀后灌胃8周。用抗β淀粉样蛋白(Aβ)5-8多克隆抗体WO2和369抗体行蛋白印迹法测鼠血清Aβ和脑的APP和CTF(α-、β、γ-CTF)蛋白含量并进行定量分析。应用免疫组织化学法观察Aβ在鼠脑中的表达。结果治疗8周后,Y-迷宫结果显示,治疗组Tg2576鼠达标所需要的训练时间显著低于对照组Tg2576鼠[(34.2±9.7)s与(52.4±12.5)s,t=3.465,P〈0.01]。旷场试验结果显示,与对照组Tg2576鼠比较,治疗组Tg2576鼠在中央格停留时间明显减低,跨格次数和站立次数增加,排泄次数减少[(4.7±3.6)s与(12.9±9.0)s,(85.3±17.6)次与(54.3±13.9)次,(57.7±17.1)次与(20.6±17.4)次,(1.2±0.6)次与(3.4±0.9)次,t=5.871、8.200、3.093、2.231,均P〈0.05)。两对照组相比较,Tg2576鼠在中央格停留时间较NTg鼠长,跨格和站立次数较NTg鼠减少[(12.9±9.0)s与(5.2±5.9)s,(54.3±13.9)次与(85.8±22.5)次,(20.6±17.4)次与(53.5±14.0)次,均P〈0.05]。上述训练项目NTg鼠治疗组和对照组的差异均无统计学意义。蛋白印迹法结果显示,与对照组Tg2576鼠比较,RNSP治疗组Tg2576鼠血清Aβ含量显著减低(t=9.104,P〈0.01),脑组织α-CTF蛋白的水平和α-CTF/β-CTF的比值明显增高(t=20.678、14.170,均P〈0.01)。但两组脑APP、β-CTF和了γ-CTF蛋白无明显变化。免疫组化染色显示,治疗组Tg2576鼠的大脑皮质和海马周围Aβ淀粉样斑块的数目明显减少。结论RNSP能提高Tg2576鼠的学习和记忆能力。可能通过激动α分泌酶活性的APP非淀粉样酶切的代谢过程来增加鼠脑组织α—CTF蛋白的水平.降低血清Aβ浓度,使老年斑的形成减少。 | 朱爱琴 Colin L Masters LI Qiao- xin | 2009 | 中华老年医学杂志2009，28，11： | 6 |
| 18 | Utility of tissue microarrays for profiling prognostic biomarkers in clinically localized prostate cancer: the expression of BCL-2, E-cadherin, Ki-67 and p53 as predictors of biochemical failure after radical prostatectomy with nested control for clinical and pathological risk factors显示文摘痊愈不能与经历激进的治疗的临床上局部性的前列腺癌症为所有人被保证。如果他们能改进秘密变形疾病的预言,分子的标记将是无价的。这研究被执行在激进的前列腺切除术标本调查 BCL-2, Ki-67, p53 和 E-cadherin 的表示。我们寻求了估计他们的能力在一个特定的治疗学的背景预言早生物化学的恶化。包括 41 案例对的 82 个病人为病理学的舞台,格利森等级和外科手术前的前列腺特定的抗原(PSA ) 被匹配集中。在每对的一个病人有生物化学的复发(在 2 年外科以内定义为 PSA 0.2 ng mL-1 ) 并且其它没有疾病生物化学地留下了(至少 3 年在外科以后定义同样无法发现的 PSA ) 。Immunohistochemical 分析被执行在四上估计标记表示复制从每个激进的前列腺切除术标本与良性、恶意的织物构造的织物 microarrays。Ki-67, p53 和 BCL-2,然而并非 E-cadherin,显著地在前列腺腺癌的 upregulated 与良性的前列腺织物相比(P < 0.01 ) 。然而,当比较与没有生物化学的复发的病人一起开发了早生物化学的恶化的病人时,在任何标记的表示的重要差别都没被观察。这研究证明 p53, BCL-2 和 Ki-67 的那表情与良性的前列腺织物相比是在临床上局部性的前列腺癌症的 upregulated,没有在 E-cadherin 表示的改变。Biomarker upregulation 没在激进的前列腺切除术以后为生物化学的复发有预示的价值,甚至在考虑病理学的舞台,整个瘤格利森等级和外科手术前的浆液 PSA 水平以后。 | Joseph Nariculam Alex Freeman Simon Bott Phillipa Munson Noriko Cable Nicola Brookman-Amissah Magali Williamson Roger S.
