| 1 | 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 |
| 2 | Mapping wetland changes in China between 1978 and 2008显示文摘Four wetland maps for all China have been produced,based on Landsat and CBERS-02B remote sensing data between 1978 and 2008 (1978,1990,2000 and 2008).These maps were mainly developed by manual interpretation and validated by substantial field investigation in 2009.Based on these maps,we analyzed the 2008 wetland distribution in China and discussed wetland changes and their drivers over the past 30 years.(i) There were about 324097 km 2 of wetlands in 2008,for which inland marshes or swamps were the most common wetland type (35%),with lakes (26%) second.Most of the wetlands were in Heilongjiang,Inner Mongolia,Qinghai and Tibet,occupying about 55% of the national wetland area.(ii) From 1978 to 2008,China's wetland area continually and significantly decreased,by about 33% based on changes in the wetland map.This was in sharp contrast to the increase in artificial wetlands,which increased by about 122%.Inland marshes accounted for the main loss of total wetlands from 1978 to 2000.From 2000 through 2008,riverine and lacustrine wetlands constituted the main wetland loss.Fortunately however,the rate of wetland loss decreased from 5523 to 831 km 2 /a.(iii) The change ratio of lost natural wetlands (including inland and coastal wetlands) to non-wetlands has decreased slightly over the past 30 years.From 1978 to 1990,nearly all natural wetlands (98%) lost were transformed into non-wetlands.However,the ratio declined to 86% from 1990 to 2000,and to 77% from 2000 to 2008.(iv) All Chinese provinces were divided into three groups according to patterns of wetland changes,which could relate to the driving forces of such changes.Tibet was completely different from other provinces,as it was one representative example in which there was a net wetland increase,because of global warming and decreased human activity since 1990.Increased economic development caused considerable wetland loss in most eastern provinces,and artificial wetlands increased. | NIU ZhenGuo ZHANG HaiYing WANG XianWei YAO WenBo ZHOU DeMin ZHAO KuiYi ZHAO Hui LI NaNa HUANG HuaBing LI CongCong YANG Jun LIU CaiXia LIU Shuang WANG Lin LI Zhan YANG ZhenZhong QIAO Fei ZHENG YaoMin CHEN YanLei SHENG YongWei GAO XiaoHong ZHU WeiHong WANG WenQing WANG Hong WENG YongLing ZHUANG DaFang LIU JiYuan LUO ZhiCai CHENG Xiao GUO ZiQi GONG Peng | 2012 | Chinese Science Bulletin2012,57,22: | 51 |
| 3 | Field experiment on a robust hierarchical metropolitan quantum cryptography network显示文摘A hierarchical metropolitan quantum cryptography network upon the inner-city commercial telecom fiber cables is reported in this paper. The seven-user network contains a four-node backbone net with one node acting as the subnet gateway, a two-user subnet and a single-fiber access link, which is realized by the Faraday-Michelson interferometer set-ups. The techniques of the quantum router, optical switch and trusted relay are assembled here to guarantee the feasibility and expandability of the quantum cryptography network. Five nodes of the network are located in the government departments and the secure keys generated by the quantum key distribution network are utilized to encrypt the instant video, sound, text messages and confidential files transmitting between these bureaus. The whole implementation including the hierarchical quantum cryptographic communication network links and the corresponding application software shows a big step toward the practical user-oriented network with a high security level. | XU FangXing CHEN Wei WANG Shuang YIN ZhenQiang ZHANG Yang LIU Yun ZHOU Zheng ZHAO YiBo LI HongWei LIU Dong HAN ZhengFu GUO GuangCan | 2009 | Chinese Science Bulletin2009,54,17: | 40 |
| 4 | Andrographolide sulfonate ameliorates lipopolysaccharide-induced acute lung injury in mice by down-regulating MAPK and NF-κB pathways显示文摘Acute lung injury(ALI) or acute respiratory distress syndrome(ARDS) is a severe, lifethreatening medical condition characterized by widespread inflammation in the lungs, and is a significant source of morbidity and mortality in the patient population. New therapies for the treatment of ALI are desperately needed. In the present study, we examined the effect of andrographolide sulfonate, a water-soluble form of andrographolide(trade name: Xi-Yan-Ping Injection), on lipopolysaccharide(LPS)-induced ALI and inflammation. Andrographolide sulfonate was administered by intraperitoneal injection to mice with LPS-induced ALI. LPS-induced airway inflammatory cell recruitment and lung histological alterations were significantly ameliorated by andrographolide sulfonate. Protein levels of pro-inflammatory cytokines in bronchoalveolar lavage fluid(BALF) and serum were reduced by andrographolide sulfonate administration. m RNA levels of pro-inflammatory cytokines in lung tissue were also suppressed. Moreover, andrographolide sulfonate markedly suppressed the activation of mitogen-activated protein kinase(MAPK) as well as p65 subunit of nuclear factor-κB(NF-κB). In summary, these results suggest that andrographolide sulfonate ameliorated LPS-induced ALI in mice by inhibiting NF-κB and MAPK-mediated inflammatory responses. Our study shows that water-soluble andrographolide sulfonate may represent a new therapeutic approach for treating inflammatory lung disorders. | Shuang Peng Nan Hang Wen Liu Wenjie Guo Chunhong Jiang Xiaoling Yang Qiang Xu Yang Sun | 2016 | Acta Pharmaceutica Sinica B2016,6,3: | 38 |

| 8 | Current status of diagnosis and treatment of bladder cancer in China-Analyses of Chinese Bladder Cancer Consortium database显示文摘Objective:To investigate current status of diagnosis and treatment of bladder cancer in China.Methods:A database was generated by Chinese Bladder Cancer Consortium(CBCC).From January 2007 to December 2012,14,260 cases from 44 CBCC centers were included.Data of diagnosis,treatment and pathology were collected.Results:The average age was 63.5 year-old and most patients were male(84.3%).The most common histologic types were urothelial carcinoma(91.4%),adenocarcinoma(1.8%),and squamous carcinoma(1.9%).According to 1973 and 2004 WHO grading system,42.0%,41.0%,and 17.0% of patients were grade 1,2,and 3,and 16.0%,48.7%,and 35.3% of patients were papillary urothelial neoplasms of low malignant potential,low,and high grade,respectively.Non-muscle invasive bladder cancer(NMIBC)and muscle invasive bladder cancer(MIBC)were 25.2% and 74.1%,respectively(0.8% not clear).Carcinoma in situ was only 2.4%.Most patients were diagnosed by white-light cystoscopy with biopsy(74.3%).Fluorescence and narrow band imaging cystoscopy had additional detection rate of 1.0% and 4.0%,respectively.Diagnostic transurethral resection(TUR)provided detection rate of 16.9%.Most NMIBCs were treated with TUR(89.2%).After initial TUR,2.6%accepted second TUR,and 45.7%,69.9%,and 58.7% accepted immediate,induced,and maintenance chemotherapy instillation,respectively.Most MIBCs were treated with radical cystectomy(RC,59.7%).Laparoscopic RCs were 35.1%,while open RC 63.4%.Extended and standard pelvic lymph node dissection were 7% and 66%,respectively.Three most common urinary diversions were orthotopic neobladder(44%),ileal conduit(31%),and ureterocutaneostomy(23%).Only 2.3% of patients accepted neo-adjuvant chemotherapy and only 18%of T3 and T4 patients accepted adjuvant chemotherapy.Conclusion:Disease characteristics are similar to international reports,while differences of diagnosis and treatment exist.This study can provide evidences for revisions of the guideline on bladder cancer in China. | Kaiwen Li Tianxin Lin 无 Wei Xue Xin Mu Enci Xu Xu Yang Fubao Chen Guangyong Li Lulin Ma Guoliang Wang Chaozhao Liang Haoqiang Shi Ming Li Mao Tang Xueyi Xue Yisong Lv Yaoliang Deng Chengyang Li Zhiwen Chen Xiaozhou Zhou Fengshuo Jin Xudong Liu Jinxin Wei Lei Shi Xin Gou Weiyang He Liqun Zhou Lin Cai Baiye Jin Guanghou Fu Xiangbo Kong Hongyan Sun Ye Tian Lang Feng Tiejun Pan Yiyi Wu Dongwen Wang Hailong Hao Benkang Shi Yaofeng Zhu Qiang Wei Ping Han Changli Wu Dawei Tian Zhangqun Ye Zheng Liu Zhiping Wang Junqiang Tian Lin Qi Minfeng Chen Wei Li Jinchun Qi Gongxian Wang Longlong Fu Zhaolin Sun Guangheng Luo Zhoujun Shen Zhaowei Zhu Jinchun Xing Zhun Wu Dong Wei Xin Chen Yanqun Na Hongfeng Guo Chunxi Wang Zhihua Lu Chuize Kong Yang Liu Jin Yang Jianyun Hu Xin Gao Jielin Li Changjun Yin Pu Li Shan Chen Zhen Du Jiongming Li Yongji Yan Xu Zhang Shuang Huang Fangjian Zhou Zhiling Zhang Yinghao Sun Shuxiong Zeng Song Cen Jiaquan Zhou Hanzhong Li Jin Wen Jian Huang | 2015 | Asian Journal of Urology2015,2,2: | 21 |
| 9 | Valproic acid reduces autophagy and promotes functional recovery after spinal cord injury in rats显示文摘Secondary damage is a critical determinant of the functional outcome in patients with spinal cord injury (SCI), and involves multiple mechanisms of which the most important is the loss of nerve cells mediated by multiple factors. Autophagy can result in cell death, and plays a key role in the development of SCI. It has been recognized that valproic acid (VPA) is neuroprotective in certain experimental animal models, however, the levels of autophagic changes in the process of neuroprotection by VPA treatment following SCI are still unknown. In the present study, we determined the extent of autophagy after VPA treatment in a rat model of SCI. We found that both the mRNA and protein levels of Beclin-1 and LC3 were significantly increased at 1, 2, and 6 h after SCI and peaked at 2 h; however, Western blot showed that autophagy was markedly decreased by VPA treatment at 2 h post-injury. Besides, post-SCI treatment with VPA improved the Basso-Beattie-Bresnahan scale, increased the number of ventral horn motoneurons, and reduced myelin sheath damage compared with vehicle-treated animals at 42 days after SCI. Together, our results demonstrated the characteristics of autophagy expression following SCI, and found that VPA reduced autophagy and enhanced motor function. | Hai-Hu Hao Li Wang Zhi-Jian Guo Lang Bai Rui-Ping Zhang Wei-Bing Shuang Yi-Jia Jia Jie Wang Xiao-Yu Li Qiang Liu | 2013 | Neuroscience Bulletin2013,29,4: | 19 |
| 10 | Serum levels of microRNAs can specifically predict liver injury of chronic hepatitis B显示文摘AIM:To investigate whether circulating microRNAs (miRNAs) can serve as molecular markers to predict liver injury resulted from chronic hepatitis B (CHB). METHODS:The profiles of serum miRNA expression were first generated with serum samples collected from 10 patients with CHB and 10 healthy donors (Ctrls) by microarray analysis. The levels of several miRNAs were further quantitated by real-time reverse transcriptionpolymerase chain reaction with serum samples from another 24 CHB patients and 24 Ctrls. Serum samples of 20 patients with nonalcohlic steatohepatitis (NASH) were also included for comparison. The comparison in the levels of miRNAs between groups (CHB, NASH and Ctrl) was analyzed with Mann-Whitney Utest. The correlation between miRNAs and clinical pathoparameters was analyzed using Spearman correlation analysis or canonical correlation analysis. The receiver-operator characteristic (ROC) curves were also generated to determine the specificity and sensitivity of each individual miRNA in distinguishing patients with CHB from Ctrls. RESULTS:miRNA profile analysis showed that 34 miRNAs were differentially expressed between CHB and Ctrl subjects, in which 12 were up-regulated and 22 down-regulated in CHB subject (fold change > 2.0 and P < 0.01). The median levels of miR-122, -572, -575 and -638 were significantly higher (P < 1.00 × 10 -5 ) while miR-744 significantly lower (P < 1.00 × 10 -6 ) in CHB compared with the Ctrl. The levels of miR-122, -572 and -638 were also higher (P < 1.00 × 10 -3 ) while the level of miR-744 lower in CHB (P < 0.05) than in NASH, although the difference between them was not as significant as that between CHB and Ctrl. ROC curve analysis revealed that the levels of miR-122, -572, -575, -638 and -744 in serum were sensitive and specific enough to distinguish CHB, NASH and Ctrl. Multivariate analysis further showed that the levels of these miRNAs were correlated with the liver function parameters. Most significantly, it was the scatter plot of principal component with the levels of these miRNAs, but not the parameters of liver function, which clearly distinguished CHB, NASH and Ctrl subjects. CONCLUSION:Serum levels of miR-122, -572, -575, -638 and -744 are deregulated in patients with CHB or NASH. The levels of these miRNAs may serve as potential biomarkers for liver injury caused by CHB and NASH. | Hui Zhang Qing-Ya Li Zhi-Zhong Guo Yan Guan Jia Du Yi-Yu Lu Yi-Yang Hu Ping Liu Shuang Huang Shi-Bing Su | 2012 | World Journal of Gastroenterology2012,18,37: | 15 |
| 11 | A Chromosome-Level Genome Assembly of Garlic (Allium sativum) Provides Insights into Genome Evolution and Allicin Biosynthesis显示文摘Garlic,an economically important vegetable,spice,and medicinal crop,produces highly enlarged bulbs and unique organosulfur compounds.Here,we report a chromosome-level genome assembly for garlic,with a total size of approximately 16.24 Gb,as well as the annotation of 57561 predicted protein-coding genes,making garlic the first Allium species with a sequenced genome.Analysis of this garlic genome assembly reveals a recent burst of transposable elements,explaining the substantial expansion of the garlic genome.We examined the evolution of certain genes associated with the biosynthesis of allicin and inulin neoseries-type fructans,and provided new insights into the biosynthesis of these two compounds.Furthermore,a large-scale transcriptome was produced to characterize the expression patterns of garlic genes in different tissues and at various growth stages of enlarged bulbs.The reference genome and large-scale transcriptome data generated in this study provide valuable new resources for research on garlic biology and breeding. | Xiudong Sun Siyuan Zhu Ningyang Li Yi Cheng Jing Zhao Xuguang Qiao Li Lu Shiqi Liu Yanzhou Wang Chan Liu Benping Li Wu Guo Shuang Gao Zemao Yang Fu Li Zheng Zeng Qing Tang Yupeng Pan Mengjiao Guan Jian Zhao Xiaomi ng Lu Huanwe n Meng Zhenlin Han Chun she ng Gao Wenkai Jiang Xing Zhao Shilin Tian Jianguang Su Zhihui Cheng Touming Liu | 2020 | Molecular Plant2020,13,9: | 14 |
| 12 | Endothelium-specific SIRT1 overexpression inhibits hyperglycemia-induced upregulation of vascular cell senescence显示文摘The rapidly increasing prevalence of diabetes mellitus worldwide is one of the most serious and challenging health problems in the 21st century.Mammalian sirtuin 1(SIRT1) has been shown to decrease high-glucose-induced endothelial cell senescence in vitro and prevent hyperglycemia-induced vascular dysfunction.However,a role for SIRT1 in prevention of hyperglycemia-induced vascular cell senescence in vivo remains unclear.We used endothelium-specific SIRT1 transgenic(SIRT1-Tg) mice and wild-type(WT) mice to construct a 40-week streptozotocin(STZ)-induced diabetic mouse model.In this mode,42.9% of wild-type(WT) mice and 38.5% of SIRT1-Tg mice were successfully established as diabetic.Forty weeks of hyperglycemia induced significant vascular cell senescence in aortas of mice,as indicated by upregulation of expression of senescence-associated markers including p53,p21 and plasminogen activator inhibitor-1(PAI-1).However,SIRT1-Tg diabetic mice displayed dramatically decreased expression of p53,p21 and PAI-1 compared with diabetic WT mice.Moreover,manganese superoxide dismutase expression(MnSOD) was significantly downregulated in the aortas of diabetic WT mice,but was preserved in diabetic SIRT1-Tg mice.Furthermore,expression of the oxidative stress adaptor p66Shc was significantly decreased in aortas of SIRT1-Tg diabetic mice compared with WT diabetic mice.Overall,these findings suggest that SIRT1-mediated inhibition of hyperglycemia-induced vascular cell senescence is mediated at least partly through the reduction of oxidative stress. | CHEN HouZao WAN YanZhen ZHOU Shuang LU YunBiao ZHANG ZhuQin ZHANG Ran CHEN Feng HAO DeLong ZHAO Xiang GUO ZhiChen LIU DePei LIANG ChihChuan | 2012 | Science China(Life Sciences)2012,55,6: | 14 |

| 14 | Combined obeticholic acid and apoptosis inhibitor treatment alleviates liver fibrosis显示文摘Obeticholic acid(OCA), the first FXR-targeting drug, has been claimed effective in the therapy of liver fibrosis. However, recent clinical trials indicated that OCA might not be effective against liver fibrosis, possibly due to the lower dosage to reduce the incidence of the side-effect of pruritus. Here we propose a combinatory therapeutic strategy of OCA and apoptosis inhibitor for combating against liver fibrosis. CCl4-injured mice, D-galactosamine/LPS(GalN/LPS)-treated mice and cycloheximide/TNFα(CHX/TNFα)-treated HepG2 cells were employed to assess the effects of OCA, or together with IDN-6556, an apoptosis inhibitor. OCA treatment significantly inhibited hepatic stellate cell(HSC)activation/proliferation and prevented fibrosis. Elevated bile acid(BA) levels and hepatocyte apoptosis triggered the activation and proliferation of HSCs. OCA treatment reduced BA levels but could not inhibit hepatocellular apoptosis. An enhanced anti-fibrotic effect was observed when OCA was co-administrated with IDN-6556. Our study demonstrated that OCA inhibits HSCs activation/proliferation partially by regulating BA homeostasis and thereby inhibiting activation of HSCs. The findings in this study suggest that combined use of apoptosis inhibitor and OCA at lower dosage represents a novel therapeutic strategy for liver fibrosis. | Jiyu Zhou Ningning Huang Yitong Guo Shuang Cui Chaoliang Ge Qingxian He Xiaojie Pan Guangji Wang Hong Wang Haiping Hao | 2019 | Acta Pharmaceutica Sinica B2019,9,3: | 13 |
| 15 | Accurate stress analysis on rigid central buckle of long-span suspension bridges based on submodel method显示文摘Runyang Suspension Bridge (RSB) with the main span of 1490 m is the longest bridge in China and the third longest one in the world. In this bridge the rigid central buckle is employed for the first time in the mid-span of the suspension bridge in China. For such a super-long-span bridge, the traditional finite element (FE) modeling technique and stress analysis methods obviously cannot satisfy the needs of conducting accurate stress analysis on the central buckle. In this paper, the submodel method is in- troduced and for the first time used in analyzing the stresses of the central buckle. After an accurate FE submodel of the central buckle was specially established according to the analysis results from the whole FE model, the connection technique between the two-scale FE models was realized and the ac- curate stresses of the central buckle under various vehicle load cases were then conducted based on the submodel method. The calculation results were testified to be accurate and reliable by the field measurements, which show the efficiency and reliability of the submodel method on analyzing the mechanical condition of the central buckle of long-span suspension bridges. Finally, the working be- havior and mechanical characteristics of the central buckle of the RSB under vehicle loads were ana- lyzed based on the calculation and measurement results. The results obtained in this paper can provide theoretic references for analyzing and designing the rigid central buckle in long-span suspension bridges in future. | WANG Hao LI AiQun GUO Tong MA Shuang | 2009 | Science China(Technological Sciences)2009,52,4: | 12 |
| 16 | The presence of phosphorylation form of D1 protein in its cross-linked aggregates in high light treated spinach leaves in vivo显示文摘In the present study, using specific antibody against D1 protein, we detected four ag- gregates of D1 protein in thylakoid membranes from spinach leaves illuminated at high light (800―2500 μmol photons·m?2·s?1) for 3 h. Their accumulations were dependent on the light intensity to which the leaves had been subjected. Further immunoblot analysis indicated that 70 kD aggregate was a prod- uct of D1 protein cross-linked with CP43, 65 and 60 kD aggregate were two cross-linked products be- tween D1 and D2 proteins, and 41 kD aggregate was one cross-linked D1 with α-subunit of cytochrome b559 (Cyt b559). This result provided the evidence for the existence of the aggregation of the D1 protein in vivo. The maximal level of D1/Cyt b559 aggregate occurred at 1000 μmol photons·m?2·s?1 but drastically decreased with further increasing light intensity. Im- munoblot analysis with phosphothreonine (Thr (P)) antibody indicated that D1/CP43 and D1/Cyt b559 aggregates contained the phosphorylated protein(s). In vitro dephosphorylation experiment also showed that D1/Cyt b559 and D1/CP43 aggregates lost the immunoreactivity with Thr (P) antibody after the phosphatase treatment of the membranes from high-light-illuminated leaves. Our results demon- strated that strong illumination of spinach leaves in- duced cross-linked products of D1 protein with its nearby polypeptides of PS Ⅱ , some of which con- tained the phosphorylated D1 protein. | WEI Huimin GUO Junwei ZHANG Shuang HUANG Bo LIU Yinqiu DU Linfang | 2006 | Chinese Science Bulletin2006,51,1: | 12 |

| 18 | Processing map of as-cast 7075 aluminum alloy for hot working显示文摘The true stress–strain curves of as-cast 7075 aluminum alloy have been obtained by isothermal compression tests at temperatures of 300–500 °C and strain rates of 0.01–10 s 1. The plastic flow instability map is established based on Gegel B and Murthy instability criteria because the deformed compression samples suggest that the combination of the above two instability criteria has more comprehensive crack prediction ability. And the processing map based on Dynamic Material Model(DMM) of as-cast 7075 aluminum alloy has been developed through a superposition of the established instability map and power dissipation map. In terms of microstructure of the deformed samples and whether plastic flow is stable or not, the processing map can be divided into five areas: stable area with as-cast grain, stable area with homogeneous grain resulting from dynamic recovery, instability area with as-cast grain, instability area with the second phase and instability area with mixed grains. In consideration of microstructure characteristics in the above five areas of the processing map, the stable area with homogeneous grain resulting from dynamic recovery, namely the temperatures at 425–465 °C and the strain rates at 0.01–1 s 1, is suggested to be suitable processing window for the as-cast 7075 aluminum alloy. | Guo Lianggang Yang Shuang Yang He Zhang Jun | 2015 | Chinese Journal of Aeronautics2015,28,6: | 10 |
| 19 | Atorvastatin activates autophagy and promotes neurological function recovery after spinal cord injury显示文摘Atorvastatin, a lipid-lowering medication, provides neuroprotective effects, although the precise mechanisms of action remain unclear. Our previous studies confirmed activated autophagy following spinal cord injury, which was conducive to recovery of neurological functions. We hypothesized that atorvastatin could also activate autophagy after spinal cord injury, and subsequently improve recovery of neurological functions. A rat model of spinal cord injury was established based on the Allen method. Atorvastatin(5 mg/kg) was intraperitoneally injected at 1 and 2 days after spinal cord injury. At 7 days post-injury, western blot assay, reverse transcription-polymerase chain reaction, and terminal deoxynucleotidyl transferase-mediated dU TP nick-end labeling(TUNEL) staining results showed increased Beclin-1 and light chain 3B gene and protein expressions in the spinal cord injury + atorvastatin group. Additionally, caspase-9 and caspase-3 expression was decreased, and the number of TUNEL-positive cells was reduced. Compared with the spinal cord injury + saline group, Basso, Beattie, and Bresnahan locomotor rating scale scores significantly increased in the spinal cord injury + atorvastatin group at 14–42 days post-injury. These findings suggest that atorvastatin activated autophagy after spinal cord injury, inhibited apoptosis, and promoted recovery of neurological function. | Shuang Gao Zhong-ming Zhang Zhao-liang Shen Kai Gao Liang Chang Yue Guo Zhuo Li Wei Wang Ai-mei Wang | 2016 | Neural Regeneration Research2016,11,6: | 9 |
| 20 | Clinicopathological significance of overexpression of interleukin-6 in colorectal cancer显示文摘AIM To compare the expression levels of interleukin(IL)-6 in colorectal cancer(CRC) tissues and adjacent noncancerous tissues, and analyse the correlation of IL-6 expression with the clinicopathological parameters of CRC. METHODS Fifty CRC tissue specimens and 50 matched adjacent mucosa specimens were collected. The expression of IL-6 in these clinical samples was examined by immunohistochemical staining. The correlation between IL-6 expression and clinicopathological parameters was assessed by statistical analysis.RESULTS IL-6 expression was significantly elevated in CRC tissues compared with noncancerous tissues(P < 0.001). IL-6 expression was positively correlated with tumour TNM stage(P < 0.001), but a negative correlation was detected between IL-6 expression and tumor histological differentiation in CRC(P < 0.05). Furthermore, IL-6 expression was associated with invasion depth and lymph node metastasis in CRC. CONCLUSION IL-6 might be a useful marker for predicting a poor prognosis in patients with CRC and might be used as a potential therapeutic target in CRC. | Jun Zeng Zhong-Hua Tang Shuang Liu Shan-Shan Guo | 2017 | World Journal of Gastroenterology2017,23,10: | 9 |
