| 4 | Alteration of p53 and p21 during hepatocarcinogenesis in tree shrews显示文摘AIM: To investigate p53 mutation and p21 expression in hepatocarcinogenesis induced by hepatitis B virus (HBV) and aflatoxin B1 (AFB1) in tree shrews, and to reveal the role of these genes in hepatocarcinogenesis.METHODS: Tree shrews were divided into four groups:group A, those infected with HBV and fed with AFB1 (n = 39);group B, those infected with HBV alone (n = 28); group C,those fed with AFB1 alone (n = 29); and group D, normal controls (n = 20). The tree shrews underwent liver biopsies once every 15 wk. Expression of p53 and p21 proteins and genes in the biopsies and tumor tissues of the experimental tree shrews was detected, respectively, by immunohistochemistry,and by Southem blotting and reverse transcription-polymerase chain reaction and sequencing.RESULTS: The incidence of hepatocellular carcinomas (HCC) was higher in group A (66.7%) than that in group B (3.57%) and C (30%). The time of HCC occurrence was also earlier in group A than that in group C (120.0±16.6 wk vs 153.3±5.8 wk, respectively, P<0.01). p53 protein was not detected by immunohistochemistry in all groups before the 75^th wk of the experiment. At the 105^th wk, the positive rates fo p53 were 78.6%, 60% and 71.4% in groups A, B and C, respectively, which were significantly higher than that in group D (10%) (all P<0.05). An abnormal band of p53 gene was observed in groups A and C. The mutation points of p53gene in tree shrews with HCC were at codons 275, 78 and 13. The nucleotide sequence and amino acid sequence of tree shrew's wild-type p53 showed 91.7% and 93.4% homologies with those of human p53,respectively. The immunopositivity for p21 was found before HCC development. The incidence of HCC was significantly higher in tree shrews that were positive for p21 than those negative for p21 (80.0% vs 11.0%, P<0.001).The incidence of HCC in p21 positive animals in group A was significantly higher than those positive for p21 in group C (P | Jian-Jia Su Yuan Li Ke-Chen Ban Liu-Liang Qin Chun Yang Chao Ou Xiao-Xian Duan Hui-Yun Wang Rui-Qi Yang Young-Lk Lee | 2004 | World Journal of Gastroenterology2004,10,24: | 21 |
| 5 | The Efficiency of Southern rice black-streaked dwarf virus Transmission by the Vector Sogatella furcifera to Different Host Plant Species显示文摘Southern rice black-streaked dwarf disease is a new rice disease that severely affects rice production in South China.To understand transmission capacity of the vector Sogatella furcifera to Southern rice black-streaked dwarf virus(SRBSDV) among different host plant species,potential host plants of SRBSDV collected from the diseased rice field and/or adjacent to the field in Hunan Province,China,were determined by RT-PCR,and the transmission rates of SRBSDV by S.furcifera among different host plant species were investigated.The results showed that host plants of SRBSDV in the rice fields were five of family Gramineae(Oryza sativa,Echinochloa crusgalli,Zea mays,Paspalum distichum,Alopecurus aequali) and two of family Cyperaceae(Juncellus serotinus and Cyperus difformis).S.furcifera could not transmit SRBSDV between gramineous plants and cyperaceous plants,and could not transmit SRBSDV between the gramineous plants,J.serotinus and C.difformis as well.However,SRBSDV could be transmitted by S.furcifera within gramineous plants.S.furcifera could transmit SRBSDV between interspecies among three species plants(O.sativa,E.crusgalli and Z.mays),and between P.distichum and A.aequali.At 15,20,25,30,and 35°C,both macropterous and brachypterous adult of S.furcifera could transmit SRBSDV from the plants(e.g.,E.crusgalli,Z.mays and O.sativa) infected with SRBSDV to rice seedlings.The transmission rates were first increased and then decreased with the increase of temperature.Macropterous adults transmitted SRBSDV from the viruliferous E.crusgalli,Z.may and rice plants to the healthy rice seedlings,and the infected rates of rice seedlings were 26.2,18.8 and 23.7% at 15°C,56.6,64.6 and 53.6% at 25°C,and was 11.2,10.2 and 7.3% at 35°C,respectively.Transmission capacity of brachypterous adults was significantly higher than that of macropterous adults at 15,20 and 25°C(P<0.05),while transmission capacity of brachypterous adults was relatively lower compared with that of macropterous ones at 35°C.These results offer evidence on the transmission of SRBSDV via the vector S.furcifer among different host plants,which can be helpful to control Southern rice black-streaked dwarf disease by the appropriate cultural measures in South China. | LI You-zhi CAO Yang ZHOU Qian GUO Hai-ming OU Oao-cai | 2012 | Journal of Integrative Agriculture2012,11,4: | 21 |

| 10 | Apoptosis of rat hepatic stellate cells induced by anti-focal adhesion kinase antibody显示文摘AIM: To explore the role of focal adhesion kinase (FAI)in the apoptosis in culture-activated rat hepatic stellatecells (HSCs) using a specific anti-FAK antibody.METHODS: Rat HSCs were prepared from Wistar rats byin situ perfusion of collagenase and pronase and single-step density Nycodenze gradient. Culture-activatedHSCs were serum-starved and treated with the anti-FAK antibodies for 24, 48 or 72 h. The apoptosis of HSCwas detected by DNA-fragment assay, flow cytometryand caspase-3 activity determination. The expressionof tissue inhibitor of metalloproteinase-1 (TIMP-1)mRNA was assessed by reverse transcriptionpolymerase chain reaction (RT-PCR).RESULTS: The experiment showed that anti-FAKantibodies induced apoptosis of culture-activated ratHSCs. This phenomenon displayed the classical featuresof apoptotic cell death (DNA fragmentation, cell cycleanalysis) after treated with 30 mg@L-1 FAK antibody for72 h, and accompanied by a significant increase ofcespase-3 activity(1208±76) vs (309±28) nmol@min-1@ g-1, t=-208.5, P<0.05. Meanwhile, treatment with theFAK antibody in HSCs could markedly decrease theTIMP-1 mRNA expression (0.07±0.01 vs 0.38±0.03, t=2.72, P<0.05).CONCLUSION: FAK plays an important role in the survivalof HSCs and the specific anti-FAK antibody could inducethe apoptosis in rat HSCs. | Xiao-Jing Liu Ou Qiang Ming-Hui Huang Laboratory of Department of Internal Medicine,West China Hospital,Sichuan University,Chengdu 610041,Sichuan Province,China Li Yang Yi-Ping Wang Department of Gastroenterology of West China Hospital,Sichuan University,Chengdu 610041,Sichuan Province,China Hong-Bin Wu Laboratory of Department of Surgery,West China Hospital,Sichuan University,Chengdu 610041,Sichuan Province,China | 2002 | World Journal of Gastroenterology2002,8,4: | 17 |
| 11 | Impact of Heat Wave in 2005 on Mortality in Guangzhou, China显示文摘Objective To assess the impact of the heat wave in 2005 on mortality among the residents in Guangzhou and to identify susceptible subpopulations in Guangzhou, China. Methods The data of daily number of deaths and meteorological measures from 2003 to 2006 in Guangzhou were used in this study. Heat wave was defined as ≥7 consecutive days with daily maximum temperature above 35.0 ℃ and daily mean temperature above the 97th percentile during the study period. The excess deaths and rate ratio (RR) of mortality in the case period compared with the reference period in the same summer were calculated. Results During the study period, only one heat wave in 2005 was identified and the total number of excess deaths was 145 with an average of 12 deaths per day. The effect of the heat wave on non-accidental mortality (RR=1.23, 95% CI: 1.11-1.37) was found with statistically significant difference. Also, greater effects were observed for cardiovascular mortality (RR=1.34, 95% CI: 1.13-1.59) and respiratory mortality (RR=1.31, 95% CI: 1.02-1.69). Females, the elderly and people with lower socioeconomic status were at significantly higher risk of heat wave-associatedmortality. Conclusion The 2005 heat wave had a substantial impact on mortality among the residents in Guangzhou, particularly among some susceptible subpopulations. The findings from the present study may provide scientific evidences to develop relevant public health policies and prevention measures aimed at reduction of preventable mortality from heat waves. | YANG Jun LIU Hua Zhang OU Chun Quan LIN Guo Zhen DING Yan ZHOU Qin SHEN Ji Chuan CHEN Ping Yan | 2013 | Biomedical and Environmental Sciences2013,26,8: | 16 |
| 12 | Percutaneous ethanol injection, radiofrequency and their combination in treatment of hepatocellular carcinoma显示文摘AIM: To evaluate the therapeutic effect and the indication of percutaneous ethanol injection (PEI),radiofrequency ablation (RFA) and their combination in treatment of hepatocellular carcinoma (HCC).METHODS: Two hundred and fifty-five patients with HCC received treatment of PEI, RFA or their combination.Group1 (< 3 cm in diameter, n=85) was treated with PEI,group2 (< 3 cm in diameter, n=153) with RFA. Group3(>3 cm in diameter, n=86) was divided into two groups.Group 3a (n=34) was treated with RFA, while group 3b(n=52) was treated with RFA for 2 wk after transcatheter arterial chemoembolization or PEI. Contrast-enhanced sonography was performed for 61 patients before and after RFA. Liver function and serum alpha-fetoprotein (AFP) were measured for all patients. Changes of the lesions on ultrasound and contrast-enhanced CT/MRI were evaluated for assessing the therapeutic responses.The 1-, 2-, 3- and 5-year survival rates were recorded after treatment.RESULTS: In group 1, the complete necrosis rate of lesions after 1 mo was 77.6% (66/85). The level of AFP declined conspicuously after 1 mo. The 1-, 2-, 3- and 5-year survival rate after treatment was 80.0% (52/65),60.4% (32/53), 52.5% (21/40) and 33.3% (7/21),respectively. In group 2, the complete necrosis rate of lesions after 1 moh was 92.2% (141/153). The level of AFP decreased conspicuously after 1 mo. The 1-, 2-,3- and 5-year survival rate after treatment was 94.6%(88/93), 73.2% (52/71), 63.5% (33/52) and 46.4%(13/28), respectively. In group 3a, the complete necrosis rate of lesions after 1 mo was 23.5% (8/34). AFP dropped down to the normal level in only one patient after 1 mo. The 1-, 2- and 3-year survival rate after treatment was 47.6% (10/21), 42.9% (6/14) and 27.3%(3/11), respectively. Only one patient was still alive after 5 years. In group 3b, the complete necrosis rate of lesions after 1 mo was 57.7% (30/52). The level of AFP decreased after 1 mo. The 1-, 2-, 3- and 5-year survival rate after treatment was 68.6% (24/35), 46.2% (12/26),36.8% (7/19) and 27.3% (3/11), respectively.CONCLUSION: The therapeutic effect of RFA on small HCC is better than that of PEI. Small HCC is the optimal indication of RFA. For recurrent HCC (diameter>3 cm),the combined treatment of RFA and PEI/ACE should be used. | Bao-Ming Luo Yan-Ling Wen Hai-Yun Yang Hui Zhi Xiao-Yun Xiao Bing Ou Jing-Sheng Pan Jian-Hong Ma | 2005 | World Journal of Gastroenterology2005,11,40: | 15 |

| 15 | Mechanization technology:The key to sugarcane production in China显示文摘Sugarcane is an important cash crop in southern China now planted on about 1.5 million ha in the main production areas in Guangxi,Zhuang Autonomous Region and Yunnan,Guangdong,and Hainan Provinces.Since the cost of labor in China is increasing rapidly and the price of local sugar is uncompetitive with the product from mechanized international producers,China needs to change its sugarcane production methods from manual work to mechanization in order to catch up with international trends in this global industry.Although a lot of effort in China have gone into sugarcane mechanization since the 1960s,the overall level of mechanization in sugarcane production is still only approximately 30%,which is about 20%lower than that achieved in the other main field crops.Almost all of the sugarcane grown in China is still harvested by hand.In order to summarize past experience and promote the mechanization of sugarcane production in China,this paper reviews the whole process of developing mechanization since 1960s and describes the current state of sugarcane mechanization in China.The research currently being undertaken and the main obstacles to be overcome in developing a mechanized sugarcane production system,are described.The design and testing of sugarcane harvesting machinery and its key components has been a significant research area by some Chinese universities,research institutes,and manufacturing companies in these past decades.This paper reviews that research and outlines the main achievements which have been made in this area.Mechanized harvesting systems for sugarcane,and the appropriate harvesting patterns suitable for different growing conditions applying in China,have also been studied.The paper concludes with some comments on the future directions for progress in China’s mechanization of sugarcane production and some policy suggestions to facilitate the industry's transition. | Ou Yinggang Malcolm Wegener Yang Dantong Liu Qingting Zheng Dingke Wang Meimei Liu Haochun | 2013 | International Journal of Agricultural and Biological Engineering2013,6,1: | 13 |
| 16 | Involvement of aquaporins in a mouse model of rotavirus diarrhea显示文摘Rotavirus diarrhea is a major worldwide cause of infantile gastroenteritis; however, the mechanism responsible for intestinal fluid loss remains unclear. Water transfer across the intestinal epithelial membrane seems to occur because of aquaporins(AQPs). Accumulating evidence indicates that alterations in AQPs may play an important role in pathogenesis. Here, we focus on changes in AQPs in a mouse model of rotavirus diarrhea. In the present study, 32 of 35 mice developed diarrhea and mild dehydration within 24 hours after infection with rotavirus strain SA11. Intestinal epithelial cells demonstrated cytoplasmic vacuolation, malaligned villi, and atrophy. AQP1 expression was significantly attenuated in the ileum and colon in comparison with controls; likewise, AQP4 and-8 protein expression were significantly decreased in the colon of rotavirus diarrhea-infected mice. In contrast, AQP3 protein expression was significantly increased in the colon of rotavirus-infected mice in comparison with controls. These results indicate that rotavirus diarrhea is associated with the downregulation of AQP1,-4, and-8 expression. Therefore, AQPs play an important role in rotavirus diarrhea. | Meiwan Cao Min Yang Zhiying Ou Dingyou Li Lanlan Geng Peiyu Chen Huan Chen Sitang Gong | 2014 | Virologica Sinica2014,29,4: | 13 |
| 17 | Tomato SlAN11 regulates flavonoid biosynthesis and seed dormancy by interaction with bHLH proteins but not with MYB proteins显示文摘The flavonoid compounds are important secondary metabolites with versatile human nutritive benefits and fulfill a multitude of functions during plant growth and development.The abundance of different flavonoid compounds are finely tuned with species-specific pattern by a ternary MBW complex,which consists of a MYB,a bHLH,and a WD40 protein,but the essential role of SlAN11,which is a WD40 protein,is not fully understood in tomato until now.In this study,a tomato WD40 protein named as SlAN11 was characterized as an effective transcription regulator to promote plant anthocyanin and seed proanthocyanidin(PA)contents,with late flavonoid biosynthetic genes activated in 35S::SlAN11 transgenic lines,while the dihydroflavonol flow to the accumulation of flavonols or their glycosylated derivatives was reduced by repressing the expression of SlFLS in this SlAN11-overexpressed lines.The above changes were reversed in 35S::SlAN11-RNAi transgenic lines except remained levels of flavonol compounds and SlFLS expression.Interestingly,our data revealed that SlAN11 gene could affect seed dormancy by regulating the expressions of abscisic acid(ABA)signaling-related genes SlABI3 and SlABI5,and the sensitivity to ABA treatment in seed germination is conversely changed by SlAN11-overexpressed or-downregulated lines.Yeast two-hybrid assays demonstrated that SlAN11 interacted with bHLH but not with MYB proteins in the ternary MBW complex,whereas bHLH interacted with MYB in tomato.Our results indicated that low level of anthocyanins in tomato fruits,with low expression of bHLH(SlTT8)and MYB(SlANT1 and SlAN2)genes,remain unchanged upon modification of SlAN11 gene alone in the transgenic lines.These results suggest that the tomato WD40 protein SlAN11,coordinating with bHLH and MYB proteins,plays a crucial role in the fine adjustment of the flavonoid biosynthesis and seed dormancy in tomato. | Yongfeng Gao Jikai Liu Yongfu Chen Hai Tang Yang Wang Yongmei He Yongbin Ou Xiaochun Sun Songhu Wang Yinan Yao | 2018 | Horticulture Research2018,5,1: | 13 |

RESULTS:Of the 69 patients submitted to laparotomy for tumor resection,curative resection(R0 resection) was performed in 40 patients,and palliative resection in 29.Thirty-one patients had only duct resection,and 38 patients had combined duct resection with liver resection including 34 total or part caudate lobes. Curative rates with the combined hepatectomy were significantly improved compared with those without additional hepatectomy(27/38 vs 13/31;χ2=5.94,P <0.05).Concomitant liver resection was associated with a decreased incidence of initial recurrence in liver one year after surgery(11/38 vs 23/31;χ2=13.98, P<0.01).The 3-year survival rate after R0 resection was 30.7%and was 10.5%for palliative resection.R0 resection improved the 3-year survival rate(30.7%vs 10.5%;χ2=12.47,P<0.01).CONCLUSION:Hepatectomy,especially including the caudate lobe combined with bile duct resection should be considered standard treatment to cure hilar cholangiocarcinoma. | Zheng Shi Ming-Zhi Yang Qing-Liang He Rong-Wen Ou You-Ting Chen | 2009 | World Journal of Gastroenterology2009,15,15: | 12 |
| 19 | The Impacts of Mosquito Density and Meteorological Factors on Dengue Fever Epidemics in Guangzhou, China, 2006-2014: a Time-series Analysis显示文摘Objective To explore the associations between the monthly number of dengue fever(DF) cases and possible risk factors in Guangzhou, a subtropical city of China. Methods The monthly number of DF cases, Breteau Index(BI), and meteorological measures during 2006-2014 recorded in Guangzhou, China, were assessed. A negative binomial regression model was used to evaluate the relationships between BI, meteorological factors, and the monthly number of DF cases. Results A total of 39,697 DF cases were detected in Guangzhou during the study period. DF incidence presented an obvious seasonal pattern, with most cases occurring from June to November. The current month's BI, average temperature(Tave), previous month's minimum temperature(Tmin), and Tave were positively associated with DF incidence. A threshold of 18.25 °C was found in the relationship between the current month's Tmin and DF incidence. Conclusion Mosquito density, Tave, and Tmin play a critical role in DF transmission in Guangzhou. These findings could be useful in the development of a DF early warning system and assist in effective control and prevention strategies in the DF epidemic. | SHEN Ji Chuan LUO Lei LI Li JING Qin Long OU Chun Quan YANG Zhi Cong CHEN Xiao Guang | 2015 | Biomedical and Environmental Sciences2015,28,5: | 12 |
| 20 | Current systemic treatment of hepatocellular carcinoma:A review of the literature显示文摘Hepatocellular carcinoma(HCC) is the fifth most common form of human cancer worldwide and the third most common cause of cancer-related deaths. The strategies of various treatments for HCC depend on the stage of tumor,the status of patient's performance and the reserved hepatic function. The Barcelona Clinic Liver Cancer(BCLC) staging system is currently used most for patients with HCC. For example,for patients with BCLC stage 0(very early stage) and stage A(early stage) HCC,the curable treatment modalities,including resection,transplantation and radiofrequency ablation,are taken into consideration. If the patients are in BCLC stage B(intermediate stage) and stage C(advanced stage) HCC,they may need the palliative transarterial chemoembolization and even the target medication of sorafenib. In addition,symptomatic treatment is always recommended for patients with BCLC stage D(end stage) HCC. In this review,we will attempt to summarize the historical perspective and the current developments of systemic therapies in BCLC stage B and C in HCC. | Kai-Wen Chen Tzu-Ming Ou Chin-Wen Hsu Chi-Ting Horng Ching-Chang Lee Yuh-Yuan Tsai Chi-Chang Tsai Yi-Sheng Liou Chen-Chieh Yang Chao-Wen Hsueh Wu-Hsien Kuo | 2015 | World Journal of Hepatology2015,7,10: | 12 |
