| 1 | Reduction of tumorigenicity of SMMC-7721 hepatoma cells by vascular endothelial growth factor antisense gene therapy显示文摘AIM To test the hypothesis to block VEGFexpression of SMMC-7721 hepatoma cells mayinhibit tumor growth using the rat hepatomamodel.METHODS Amplifiy the 200 VEGF cDNAfragment and insert it into human U6 genecassette in the reverse orientation transcribingsmall antisense RNA which could specificallyinteract with VEGF165, and VEGF121 mRNA.Construct the retroviral vector containing thisantisense VEGF U6 cassette and package thereplication-deficient recombinant retrovirus.SMMC-7721 cells were transduced with thesevirus and positive clones were selected withG418. PCR and Southern blot analysis wereperformed to determine if U6 cassette integratedinto the genomic DNA of positive clone.Transfected tumor cells were evaluated for RNAexpression by ribonuclease protection assays.The VEGF protein in the supernatant of parentaltumor cells and genetically modified tumor cellswas determined with ELISA. In vitro and in vivogrowth properties of antisense VEGF cell clonein nude mice were analyzed.RESULTS Restriction enzyme digestion andPCR sequencing verified that the antisense VEGFRNA retroviral vector was successfullyconstructed. After G418 selection, resistantSMMC-7721 cell clone was picked up. PCR andSouthern blot analysis suggested that U6cassette was integrated into the cell genomicDNA. Stable SMMC-7721 cell clone transducedwith U6 antisense RNA cassette could express200bp small antisense VEGF RNA and secretereduced levels of VEGF in culture condition.Production of VEGF by antisense transgeneexpressing cells was 65 ± 10 ng / L per 106 cells,420 ± 45 ng/L per 106 cells in sense group and 485± 30 ng/L per 106 cells in the negative control group, (P<0.05). The antisense-VEGF cell clone appeared phenotypically indistinguishable from SMMC-7721 cells and SMMC-7721 cells transfected sense VEGF. The growth rate of the antisense-VEGF cell clone was the same as the control cells. When S. C. was implanted into nude mice, growth of antisense-VEGF cell lines was greatly inhibited compared with control cells.CONCLUSION Expression of antisense VEGFRNA in SMMC-7721 cells could decrease thetumorigenicity, and antisense-VEGF genetherapy may be an adjuvant treatment forhepatoma. | Yu Cheng Tang Yu Li Guan Xiang Qian Department of Biochemistry, Shanghai Second Medical University, Shanghai 200025, China | 2001 | World Journal of Gastroenterology2001，7，1： | 33 |

| 8 | Early constraint-induced movement therapy affects behavior and neuronal plasticity in ischemia-injured rat brains显示文摘Constraint-induced movement therapy is an effective rehabilitative training technique used to improve the restoration of impaired upper extremity movement after stroke. However, whether constraint-induced movement therapy is more effective than conventional rehabilitation in acute or sub-acute stroke remains controversial. The aim of the present study was to identify the optimal time to start constraint-induced movement therapy after ischemic stroke and to explore the mechanisms by which constraint-induced movement therapy leads to post-stroke recovery. Sixty-four adult male Sprague-Dawley rats were randomly divided into four groups: sham-surgery group, cerebral ischemia/reperfusion group, early constraint-induced movement therapy group, and late constraint-induced movement therapy group. Rat models of left middle cerebral artery occlusion were established according to the Zea Longa line embolism method. Constraint-induced movement therapy was conducted starting on day 1 or day 14 in the early constraint-induced movement therapy and late constraint-induced movement therapy groups, respectively. To explore the effect of each intervention time on neuromotor function, behavioral function was assessed using a balance beam walking test before surgery and at 8 and 21 days after surgery. The expression levels of brain-derived neurotrophic factor, nerve growth factor and Nogo receptor were evaluated using real time-polymerase chain reaction and western blot assay to assess the effect of each intervention time. The results showed that the behavioral score was significantly lower in the early constraint-induced movement therapy group than in the cerebral ischemia/reperfusion and late constraint-induced movement therapy groups at 8 days. At 21 days, the scores had significantly decreased in the early constraint-induced movement therapy and late constraint-induced movement therapy groups. At 8 days, only mild pyknosis appeared in neurons of the ischemic penumbra in the early constraint-induced movement therapy group, which was distinctly better than in the cerebral ischemia/reperfusion group. At 21 days, only a few vacuolated cells were observed and no obvious inflammatory cells were visible in late constraint-induced movement therapy group, which was much better than at 8 days. The mRNA and protein expression levels of brain-derived neurotrophic factor and nerve growth factor were significantly higher, but expression levels of Nogo receptor were significantly lower in the early constraint-induced movement therapy group compared with the cerebral ischemia/reperfusion and late constraint-induced movement therapy groups at 8 days. The changes in expression levels at 21 days were larger but similar in both the early constraint-induced movement therapy and late constraint-induced movement therapy groups. Besides, the protein nerve growth factor level was higher in the late constraint-induced movement therapy group than in the early constraint-induced movement therapy group at 21 days. These results suggest that both early(1 day) and late(14 days) constraint-induced movement therapy induces molecular plasticity and facilitates functional recovery after ischemic stroke, as illustrated by the histology. The mechanism may be associated with downregulation of Nogo receptor expression and upregulation of brain-derived neurotrophic factor and nerve growth factor expression. | Xi-Hua Liu Hong-Yan Bi Jie Cao Shuo Ren Shou-Wei Yue | 2019 | Neural Regeneration Research2019，14，5： | 11 |
| 9 | Cytotoxicity evaluation and hepatoprotective potential of bioassay guided fractions from Feronia limmonia Linn leaf显示文摘Objective:To evaluate the cytotoxicity and hepatoprotective potentials of extracts,fractions or isolated compound from the leaves of Feronia limonia(F.limonia).Methods:Qualitative phytochemical analysis of extracts,fractions or compound was performed by means of thin layer chromatography and spectroscopic assays.The%purity of compound was measured by analytical HPLC.Extracts,fractions or compound have been individually evaluated for their cytotoxicity effects(10,20,100,250,500,750 and 1 000 μg/mL).Based on the inhibitory concentration(IC_(50)) obtained from the cell viability assay,graded concentrations of extracts,fractions or isolated compound were assessed(10,20,50,100,200 μg/mL) for its hepatoprotective potential against CCl_4-induced hepatotoxicity by monitoring activity levels of serum glutamatic pyruvatic transaminase(SGPT) and serum glutamic oxaloacetic transaminase(SGOT).Results:Results indicated that the methanol extract of F.limonia was non-toxic and hepatoprotective in nature as compared with the petroleum ether extract.The acetone fraction of methanolic extract also showed similar properties but the subsequent two fractions were cytotoxic.However,the pure compound isolated from the penultimate fraction of methanolic extract was non-toxic and hepatoprotective in nature.Biochemical investigations(SCOT,SCPT) further corroborated these cytological observations.Conclusions:It can be concluded from this study that F.limonia methanol extract,some fractions and pure isolated compound herein exhibit hepatoprotective activity.However,cytotoxicity recorded in the penultimate fraction and investigation of structural details of pure compound warrants further study. | Mahendra Jain Rakhee Kapadia Ravirajsinh N Jadeja Menaka C Thounaojam Ranjitsinh V Devkar SH Mishra | 2011 | Asian Pacific Journal of Tropical Biomedicine2011，1，6： | 11 |
| 10 | Expression of the difference between the Cold(Han) and Hot(Re) natures of traditional Chinese medicines(Strobal and Rhubarb) based on the cold/hot plate differentiating assay显示文摘In this study, objective differences between the Cold (Han) and Hot (Re) nature of traditional Chinese medicines, e.g. Strobal and Rhubarb, are determined by using a cold/hot plate differentiation technology. A novel, self-designed cold/hot plate differentiating instrument, with methodological study, was used to investigate the intervention of Strobal and Rhubarb on the temperature tropism of mice. Compared with the ICR and BALB/c mice, it was found that KM mice on the cold/hot plate were more sensitive to the change of temperature, within the tolerant temperature range of 15-40 ℃ . The temperature tropism behavior of mice is influenced by treatment with Rhubarb and Strobal, as is the activity of ATPase in liver tissue. These trends are consistent with the definition of the Cold/Hot nature of Chinese medicines based on traditional Chinese medicinal theory. This study showed that the differences of the Cold/Hot nature of traditional Chinese medicines. might be objectively represented by the temperature tropism of animal by means of cold/hot differentiating assay. | ZHAO HaiPing1,2, ZHAO YanLing1, WANG JiaBo1, LI HanBing1,2, REN YongShen1,2, ZHOU CanPing1,3, YAN Dan1 & XIAO XiaoHe1· 1 China Military Institute of Chinese Materia Medica, 302 Military Hospital, Beijing 100039, China 2 Chengdu University of Traditional Chinese Medicine, Chengdu 610075, China 3 Hunan University of Chinese Medicine, Changsha 410208, China | 2009 | Science China(Life Sciences)2009，52，12： | 10 |
| 11 | Angiogenesis-related cytokines in serum of proliferative diabetic retinopathy patients before and after vitrectomy显示文摘AIM: To evaluate serum concentrations of angiogenesis- related cytokines in proliferative diabetic retinopathy (PDR) before and after vitrectomy. METHODS: Serum samples were collected from 30 PDR patients with varying severity before and after vitrectomy. Serum concentrations of vascular endothelial growth factor (VEGF), pigment epithelium-derived factor (PEDF), interleukin-8 (IL-8) and interferon-inducible protein-10 (IP-10) were determined by enzyme-linked immunosorbent assays(ELISA). RESULTS: Serum concentrations of VEGF, PEDF, IL-8 and IP-10 were significantly higher in PDR patients than that in controls, respectively (P <0.05). VEGF concentration decreased significantly in postoperative samples than that in preoperative samples (P <0.05). The concentrations of PEDF, IL-8 and IP-10 did not exhibit significant changes after vitrectomy. CONCLUSION: Elevated cytokines levels in serum may be diagnostically useful in PDR. Angiogenesis-related cytokines play important roles in the development of PDR, and would instruct the risk assessment of pathogenetic condition in PDR patients. | Shuang Li Xun-An Fu Xiao-Fang Zhou You-Yan Chen Wei-Qun Chen | 2012 | International Journal of Ophthalmology(English edition)2012，5，6： | 9 |

| 14 | Cartilage oligomeric matrix protein: A novel non-invasive marker for assessing cirrhosis and risk of hepatocellular carcinoma显示文摘AIM: To assess serum cartilage oligomeric matrix protein(COMP) as a marker of cirrhosis and risk of progression to hepatocellular carcinoma(HCC). METHODS: A COMP enzyme-linked immunosorbentassay was used to test 187 patients with chronic liver diseases at the time point of first evaluation. The selected patients included 72 with chronic hepatitis B infection, 75 with chronic hepatitis C infection, 22 with primary biliary cirrhosis, 7 with autoimmune hepatitis type 1, and 11 with alcoholic liver disease. Demographic, biochemical, histological and clinical characteristics of the patients were recorded at the first evaluation. One hundred and forty-seven patients were followed for a median [interquartile range(IQR)] duration of 96.5(102) mo. The clinical, biochemical and histological data, as well as the development of cirrhosis, HCC according to internationally accepted criteria and in case of death, a liver-related cause during the follow-up period, were recorded at the electronic database of our clinic. COMP determination was also performed in 43 healthy individuals who served as the control study group.RESULTS: COMP positivity(> 15 U/L) was detected in 22%-36% among chronic liver disease groups. Strikingly, almost 83% of COMP-positive patients were cirrhotic at baseline, independently of cause of liver disease. Among the patients who developed HCC during follow-up, 73.7%(14/19) were COMP positive at baseline. COMP positivity was significantly associated with older age(P < 0.001), advanced fibrosis(P = 0.001) and necroinflammatory activity(P = 0.001), higher aspartate aminotransferase(P < 0.001), alanine aminotransferase(P < 0.02), γ-glutamyl transpeptidase(P = 0.003), alkaline phosphatase(P = 0.001), bilirubin(P < 0.05), international normalized ratio(P = 0.002) and alpha-fetoprotein levels(P < 0.02), and lower albumin(P < 0.001), and platelet count(P = 0.008). COMP levels [median(IQR)] were significantly higher in cirrhotics compared to non-cirrhotics [13.8(7.9) U/L vs 9.8(4.6) U/L, respectively; P < 0.001]. On multivariate logistic regression analysis, COMP-positivity was independently associated only with cirrhosis(OR = 4.40, 95%CI: 1.33-14.69, P = 0.015). Kaplan-Meier analysis showed that COMP positivity was significantly associated with HCC development(P = 0.007) and higher incidence of liver-related death(P < 0.001). CONCLUSION: Elevated COMP levels are strongly associated with cirrhosis and HCC progression. Serum COMP is a new promising non-invasive biomarker for HCC risk assessment in surveillance programs. | Gary L Norman Nikolaos K Gatselis Zakera Shums Christos Liaskos Dimitrios P Bogdanos George K Koukoulis George N Dalekos | 2015 | World Journal of Hepatology2015，7，14： | 7 |
| 15 | Stomatocyte structural color-barcode micromotors for multiplex assays显示文摘Artificial micromotors have a demonstrated value in the biomedical area.Attempts to develop this technology tend to impart micromotors with novel functions to improve the values.Herein,we present novel structural color-barcode micromotors for the multiplex assays.We found that,by rapidly extracting solvent and assembling monodispersed nanoparticles in droplets,it could form stomatocyte colloidal crystal clusters,which not only showed striking structural colors and characteristic reflection peaks due to their ordered nanoparticles arrangement,but also provided effective cavities for the integration of functional elements.Thus,the micromotors with catalysts or magnetic elements in their cavities,as well as with the corresponding structural color coding,could be achieved by using the platinum and ferric oxide dispersed pre-gel to fill and duplicate the stomatocyte colloidal crystal clusters.We have demonstrated that the self-movement of these structural color-barcode micromotors could efficiently accelerate the mixing speed of the detection sample and greatly increase the probe-target interactions towards faster and more sensitive single or multiplex detection,and the magnetism of these barcode micromotors enables the flexible collection of the micromotors,which could facilitate the detection processes.These features make the stomatocyte structural color-barcode micromotors ideal for biomedical applications. | Lijun Cai Huan Wang Yunru Yu Feika Bian Yu Wang Keqing Shi Fangfu Ye Yuanjin Zhao | 2020 | National Science Review2020，7，3： | 7 |
| 16 | Development of a high-throughput assay for the HIV-1 integrase disintegration reaction显示文摘Both HIV-1 integrase (IN) and the central catalytic domain of IN (IN-CCD) catalyze the disintegration reaction in vitro.In this study,IN and IN-CCD proteins were expressed and purified,and a high-throughput format enzyme-linked immunosorbent assay (ELISA) was developed for the disintegration reaction.IN exhibited a marked preference for Mn2+ over Mg2+ as the divalent cation cofactor in disintegration.Baicalein,a known IN inhibitor,was found to be an IN-CCD inhibitor.The assay is sensitive and specific for the study of disintegration reaction as well as for the in vitro identification of antiviral drugs targeting IN,especially targeting IN-CCD. | HE HongQiu,LIU Bin,ZHANG XiaoYi,CHEN WeiZu & WANG CunXin College of Life Science and Bioengineering,Beijing University of Technology,Beijing 100124,China | 2010 | Science China(Life Sciences)2010，53，2： | 7 |
