| 2 | Network Pharmacology-based Approaches Capture Essence of Chinese Herbal Medicines显示文摘Traditional Chinese Medicine(TCM), a crucial component of the current medical system, has been extensively used in clinical practice due to its valuable therapeutic efficacy, and its potentials as an important source of new pharmacophores. TCM is characterized by holistic theory, which emphasizes maintaining the balance of the patient's whole body using herbal formulae(fangji in Chinese) composed of mixtures of herbs with multiple bioactive ingredients. Because of the complex nature of these formulae, it is necessary to develop systematic methods to identify their bioactive ingredients and to clarify their mechanisms of action. With the rapid progress in bioinformatics, systems biology, and polypharmacology, 'network pharmacology', which shifts the 'one target, one drug' paradigm to the 'network target, multi-component' strategy, has attracted the attention because it can not only reveal the underlying complex interactions between a herbal formula and cellular proteins but detect the influence of their interactions on the function and behavior of the system. Growing evidence shows that the network pharmacology strategy can be a powerful approach to modern research on TCM. The present paper focuses on the basis of network pharmacology and the recent progress in its methodology, illustrates its utility in screening bioactive ingredients and elucidating the mechanisms of action of TCM herbal formulae, analyzes its limitations and problems, and discusses its development direction and application prospects. | Yan-qiong Zhang Xia Mao Qiu-yan Guo Na Lin Shao Li | 2016 | Chinese Herbal Medicines2016,8,2: | 87 |

| 4 | Adjuvant transcatheter arterial chemoembolization after curative resection for hepatocellular carcinoma patients with solitary tumor and microvascular invasion: a randomized clinical trial of efficacy and safety显示文摘Background:The optimal strategy for adjuvant therapy after curative resection for hepatocellular carcinoma(HCC)patients with solitary tumor and microvascular invasion(MVI)is controversial.This trial evaluated the efficacy and safety of adjuvant transcatheter arterial chemoembolization(TACE)after hepatectomy versus hepatectomy alone in HCC patients with a solitary tumor≥5 cm and MVI.Methods:In this randomized,open-labeled,phase III trial,HCC patients with a solitary tumor≥5 cm and MVI were randomly assigned(1:1)to receive either 1-2 cycles of adjuvant TACE after hepatectomy(Hepatectomy-TACE)or hepatectomy alone(Hepatectomy Alone).The primary endpoint was disease-free survival(DFS);the secondary end-points included overall survival(OS)and adverse events.Results:Between June 1,2009,and December 31,2012,250 patients were enrolled and randomly assigned to the Hepatectomy-TACE group(n=125)or the Hepatectomy Alone group(n=125).Clinicopathological characteristics were balanced between the two groups.The median follow-up time from randomization was 37.5 months[interquartile range 18.3-48.2 months].The median DFS was significantly longer in the Hepatectomy-TACE group than in the Hepatectomy Alone group[17.45 months(95%confidence interval[CI]11.99-29.14)vs.9.27 months(95%CI 6.05-13.70),hazard ratio[HR]=0.70(95%CI 0.52-0.95),P=0.020],respectively.The median OS was also significantly longer in the Hepatectomy-TACE group than in the Hepatectomy Alone group[44.29 months(95%CI 25.99-62.58)vs.22.37 months(95%CI 10.84-33.91),HR=0.68(95%CI 0.48-0.97),P=0.029].Treatment-related adverse events were more frequently observed in the Hepatectomy-TACE group,although these were generally mild and manageable.The most common grade 3 or 4 adverse events in both groups were neutropenia and liver dysfunction.Conclusion:Hepatectomy followed by adjuvant TACE is an appropriate option after radical resection in HCC patients with solitary tumor≥5 cm and MVI,with acceptable toxicity. | Wei Wei Pei-En Jian Shao-Hua Li Zhi-Xing Guo Yong-Fa Zhang Yi-Hong Ling Xiao-Jun Lin Li Xu Ming Shi Lie Zheng Min-Shan Chen Rong-Ping Guo | 2018 | Cancer Communications2018,38,1: | 62 |
| 5 | Entransy dissipation number and its application to heat exchanger performance evaluation显示文摘Based on the concept of the entransy which characterizes heat transfer ability, a new heat exchanger performance evaluation criterion termed the entransy dissipation number is established. Our analysis shows that the decrease of the entransy dissipation number always increases the heat exchanger effectiveness for fixed heat capacity rate ratio. Therefore, the smaller the entransy dissipation number, the better the heat exchanger performance is. The entransy dissipation number in terms of the number of exchanger heat transfer units or heat capacity rate ratio correctly exhibits the global performance of the counter-, cross-and parallel-flow heat exchangers. In comparison with the heat exchanger performance evaluation criteria based on entropy generation, the entransy dissipation number demon-strates some distinct advantages. Furthermore, the entransy dissipation number reflects the degree of irreversibility caused by flow imbalance. | GUO JiangFeng CHENG Lin XU MingTian | 2009 | Chinese Science Bulletin2009,54,15: | 58 |
| 6 | 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 |
| 7 | High-dose Iodized Oil Transcatheter Arterial Chemoembolization For Patients with Large Hepatocellular Carcinoma显示文摘AIM:To conduct a randomized trial to evaluate the role ofusing high-dose iodized oil transcatheter arterialchemosmbolization(TACE)in the treatment of largehepatocellular carcinoma(HCC).METHODS:From January 1993 to June 1998,473 patientswith unresectable hepatocellular carcinoma ware divided intotwo groups:216 patients in group A received more than20mL iodized oil during the first TACE treatment;257patients in group B received 5-15mL iodized oil in the sameway.The Child's classification and ICG-R15 for evaluatingthe liver function of the patients ware done before thetreatment.During the TACE procedure the catheters wasinserted into the target artery selectively and the tumorvessels ware demonstrated with contrast medium in thehepatic angiography.The anticancar drugs mixed withiodized oil(Lipiodol)ware Epirubicin and Mitomycin.Ingroup A,112 cases received 20-29mL Lipiodol in the firstprocedure,85 cases 30-39mL,19 cases more than 40mL.The largest dose was 53 mL and the average dose was28.3mL.In group B,119 cases received 5-10mL Lipiodol,138 cases received 11-15mL,and the average dose was11.8mL.RESULTS:High-dose Lipiodol chemoembolization causedtolerable side effects and a little hurt to the liver function inthe patients with Child grade A or ICG-R15<20.But thepatients with child grade B or ICG-R15>20 had higher risk ofliver failure after high-dose TACE.More type Ⅱ and type Ⅱlipiodol accumulations in CT scan after 4 weeks of TACEware seen in the group A patients than those in the group Bpatients(P<0.01).The resection rate and complete tumornecrosis rate in group A ware higher than those of group B(P<0.05).The 1-,2-,3-year survival rates of group Apatients with Child grade A ware 79.2%,51.8% and 34.9%,respectively,better then those of group B(P<0.001).CONCLUSION:High-dose Lipiodol can result in morecomplete tumor necrosis by blocking both arteries and small portal veins of the tumor.High-dose TACE for treatment oflarge and hypervascular hepatocallular carcinoma ispractically acceptable with the better effect than the routinedose.For the patients with large and hypervascular tumor ofChild grade A liver function or ICG-R15 less than 20%,oilychemoembolization with 20-40mL Lipiodol is recommended. | Min-Shan Chen Jin-Qing Li Ya-Qi Zhang Yun-Fei Yuan Yong-Ping Guo Xiao-Jun Lin Guo-Hui Lim Department of Hepatobiliary Cancer Center of Sun Yet-sen University of Medical Sciences,Guangzhou 510060,China Li-Xia Lu Wei-Zhang Zhang Department of Radiology Cancer Center of Sun Yet-sen University of Medical Sciences,Guangzhou 510060,China | 2002 | World Journal of Gastroenterology2002,8,1: | 58 |
| 8 | Principle of equipartition of entransy dissipation for heat exchanger design显示文摘In the present work,a principle of equipartition of entransy dissipation(EoED) for heat exchanger design is established,which says that for a heat exchanger design with given heat duty and heat transfer area,the total entransy dissipation rate reaches the minimum when the local entransy dissipation rate is uniformly distributed along the heat exchanger.When the heat transfer coefficient is unfixed,the total entransy dissipation obtained by the EoED principle is less than that obtained by the principle of equipartition of temperature difference(EoTD).Furthermore,the exchanger effectiveness obtained by the EoED principle is larger than that obtained by the EoTD principle.When the heat transfer coefficient is fixed,the EoED principle is equivalent to the EoTD principle.We show that the equipartition of entropy production(EoEP) and EoED principles give rise to difference in entropy generation and entransy dissipation for a heat exchanger optimization design.The discrepancies are caused by distinct features of entropy production minimization and entransy dissipation minimization principles,the former is to optimize the design of heat exchanger by making the lost available work minimum,while the latter is not involved with heat-work conversion.It is found that the entropy generation number is not suitable for evaluating heat exchanger performance,since it directly depends on the inlet and outlet temperatures of working fluids.On the contrary,the entransy dissipation number is not directly related to the inlet and outlet temperatures of working fluids.Therefore,the entransy dissipation number is more suitable for serving as a criterion to evaluate heat exchanger performance. | GUO JiangFeng,XU MingTian & CHENG Lin Institute of Thermal Science and Technology,Shandong University,Jinan 250061,China | 2010 | Science China(Technological Sciences)2010,53,5: | 46 |
| 9 | Effects of AT1 receptor antagonist,Iosartan,on rat hepatic fibrosis induced by CCl_4显示文摘AIM To investigate effect of losartan,an AT1receptor antagonist,on hepatic fibrosis induced byCCl;and to determine whether or not AT1receptors are expressed on hepatic stellate cells,METHODS AND RESULTS Fifty male Sprague-Dawley rats,weighing(180±20)g,wererandomized into five groups(control group,modelgroup,and three losartan treated groups),inwhich all rats were given the subcutaneousinjection of 40% CCl4(every 3 days for 6 weeks)except for rats of control group.Rats of losartan-treated groups were treated with losartan(20 mg/kg,10 mg/kg,5 mg/kg,daily gavage),After 6weeks liver tissue and serum samples of all ratswere examined.Serum hyaluronic acid(HA),procollagen typeⅢ(PCⅢ)were detected byradioimmunoassays,van Giesion collagen stainingwas used to evaluate the extracellular matrix of ratswith liver fibrosis.The expression of AT1receptors,transforming growth factor-beta(TGF-β),and alpha-smooth muscle actin(a-SMA)inliver tissue were determined byimmunohistochemical techniques.Compared withmodel group,serum ALT and AST of losartan-treated groups were significantly reduced(t=4.20,P<0.01 and t=4.57,P<0.01).Serum HAand PCⅢalso had significant differences(t=3.53,P<0.01 and t=2.20,P<0.05).Thedegree of fibrosis was improved by losartan and correlated with the expressions of AT1 receptors,TGF-β,and α-SMA in liver tissue.CONCLUSION AT1 receptor antagonist,losartan,could limit the progression of the hepatic fibrosisinduced by CCl4.The mechanism may be related tothe decrease in the expression of AT1 receptorsand TGF-β,ameliorating the injury of hepatocytes;activation of local renin-angiotensin system mightrelate to hepatic fibrosis;and during progressionof fibrosis,activated hepatic stellate cells mightexpress AT1 receptors. | Hong Shan Wei Ding Guo Li Han Ming Lu Yu Tao Zhan Zhi Rong Wang Xin Huang Jing Zhang Ji Lin Cheng Qin Fang Xu Department of Gastroenterology,Xinhua Hospital,Shanghai Second Medical University,Shanghai 200092,China | 2000 | World Journal of Gastroenterology2000,6,4: | 42 |

| 11 | Effects of dietary supplementation of probiotic,Clostridium butyricum,on growth performance,immune response,intestinal barrier function,and digestive enzyme activity in broiler chickens challenged with Escherichia coli K88显示文摘Background:Colibacillosis caused by enterotoxigenic Escherichia coli(E.coli) results in economic losses in the poultry industry.Antibiotics are usually used to control colibacillosis,however,E.coli has varying degrees of resistance to different antibiotics.Therefore the use of probiotics is becoming accepted as an alternative to antibiotics.In this study,we evaluated the effects of Clostridium butyricum(C.butyricum) on growth performance,immune response,intestinal barrier function,and digestive enzyme activity in broiler chickens challenged with Escherichia coli(E.coif) K88.Methods:The chickens were randomly divided into four treatment groups for 28 days.Negative control treatment(NC) consisted of birds fed a basal diet without E.coli K88 challenge and positive control treatment(PC) consisted of birds fed a basal diet and challenged with E.coli K88.C.butyricum probiotic treatment(CB) consisted of birds fed a diet containing 2×10~7 cfu C butyricum/kg of diet and challenged with E.coli K88.Colistin sulfate antibiotic treatment(CS)consisted of birds fed a diet containing 20 mg colistin sulfate/kg of diet and challenged with E.coli K88.Results:The body weight(BW) and average day gain(ADG) in the broilers of CB group were higher(P< 0.05) than the broilers in the PC group overall except the ADG in the 14-21 d post-challenge.The birds in CB treatment had higher(P < 0.05) concentration of tumor necrosis factor-α(TNF-α) at 3 and 7 d post-challenge,and higher(P < 0.05)concentration of interleukin-4(IL-4) at 14 d post-challenge than those in the PC treatment group.The concentration of serum endotoxin in CB birds was lower(P<0.05) at 21 d post-challenge,and the concentrations of serum diamine oxidase in CB birds were lower(P < 0.05) at 14 and 21 d post-challenge than in PC birds.Birds in CB treatment group had higher(P< 0.05) jejunum villi height than those in PC,NC,or CS treatment at 7,14,and 21 d post-challenge.In comparison to PC birds,the CB birds had lower(P < 0.05) jejunum crypt depth during the whole experiment.The birds in CB or CS treatment group had higher(P < 0.05) activities of amylase and protease at 3,7,and 14 d post-challenge,and higher(P< 0.05) activity of lipase at 3,7 d post-challenge than PC birds.Conclusions:In all,these results indicate that dietary supplementation with C.butyricum promotes immune response,improves intestinal barrier function,and digestive enzyme activities in broiler chickens challenged with E.coli K88.There is no significant difference between the C.butyricum probiotic treatment and the colistin sulfate antibiotic treatment.Therefore,the C.butyricum probiotic may be an alternative to antibiotic for broiler chickens. | Ling Zhang Lingling Zhang Xiu'an Zhan Xinfu Zeng Lin Zhou Guangtian Cao An'guo Chen Caimei Yang | 2016 | Journal of Animal Science and Biotechnology2016,7,1: | 43 |
| 12 | Anatomical and chemical characteristics associated with lodging resistance in wheat显示文摘Anatomical and chemical characteristics of stems affect lodging in wheat(Triticum aestivum L.) cultivars. Traits associated with lodging resistance, such as plant height, stem strength, culm wall thickness, pith diameter, and stem diameter, were extensively investigated in earlier studies. However, the solid stem trait was rarely considered. In this study, we measured a range of anatomical and chemical characteristics on solid and hollow stemmed wheat cultivars. Significant correlations were detected between resistance to lodging and several anatomical features, including width of mechanical tissue, weight of low internodes, and width of stem walls. Morphological features that gave the best indication of improved lodging resistance were increased stem width, width of mechanical tissue layer, and stem density. Multiple linear regression analysis showed that 99% of the variation in lodging resistance could be explained by the width of the mechanical tissue layer, suggesting that solid stemmed wheat has several anatomical features for increasing resistance to lodging. In addition, microsatellite markers GWM247 and GWM340 were linked to a single solid stem QTL on chromosome 3BL in a population derived from the cross Xinongshixin(solid stem)/Line 3159(hollow stem). These markers should be valuable in breeding wheat for solid stem. | Eryan Kong Dongcheng Liu Xiaoli Guo Wenlong Yang Jiazhu Sun Xin Li Kehui Zhan Dangqun Cui Jinxing Lin Aimin Zhang | 2013 | The Crop Journal2013,1,1: | 43 |
| 13 | Transarterial chemoembolization as initial treatment for unresectable hepatocellular carcinoma in southern China显示文摘AIM:To identify prognostic factors from pretreatment variables of the initial transarterial chemoembolization(TACE)procedure in unresectable hepatocellular carcinoma(HCC). METHODS:One thousand and five hundred and sixtynine patients with unresectable HCC underwent TACE as initial treatment were retrospectively studied.Pretreatment variables of the initial TACE procedure with a P value less than 0.05 by univariate analysis were subjected to Cox proportional hazards model. RESULTS:The median overall survival time and 1-, 5-,10-year survival rates were 10.37 mo,47%,10%, and 7%,respectively.A Cox proportional hazard model showed that 8 pretreatment factors of regional lymphnodes metastasis,Child-Pugh class,macrovascular invasion,greatest dimension,α-fetoprotein(AFP), Hepatitis virus B,tumor capsule,and nodules were independent prognostic factors.Patients with multimodality therapy have better survival than those with TACE treatment only. CONCLUSION:Tumor status,hepatic function reserve,AFP,and hepatitis virus B status were independent prognostic factors for unresectable HCC.Distant metastasis might not be a contraindication to TACE. Multimodality therapy might improve survival. | Shi, Ming Chen, Ji-An Lin, Xiao-Jun Guo, Rong-Ping Yuan, Yun-Fei Chen, Min-Shan Zhang, Ya-Qi Li, Jin-Qing | 2010 | World Journal of Gastroenterology2010,16,2: | 37 |

| 17 | Volatile profile analysis and quality prediction of Longjing tea(Camellia sinensis) by HS-SPME/GC-MS显示文摘This study aimed to analyze the volatile chemical profile of Longjing tea, and further develop a prediction model for aroma quality of Longjing tea based on potent odorants. A total of 21 Longjing samples were analyzed by headspace solid phase microextraction (HS-SPME) coupled with gas chromatography-mass spectrometry (GC-MS).Pearson's linear correlation analysis and partial least square (PLS) regression were applied to investigate the relationship between sensory aroma scores and the volatile compounds. Results showed that 60 volatile compound scould be commonly detected in this famous green tea. Terpenes and esters were two major groups characterized,representing 33.89% and 15.53% of the total peak area respectively. Ten compounds were determined to contribute significantly to the perceived aroma quality of Longjing tea, especially linalool (0.701), nonanal (0.738), (Z)-3-hexenyl hexanoate (-0.785), and β-ionone (-0.763). On the basis of these 10 compounds, a model (correlation coefficient of89.4% and cross-validated correlation coefficient of 80.4%) was constructed to predict the aroma quality of Longjingtea. Summarily, this study has provided a novel option for quality prediction of green tea based on HS-SPME/GC-MStechnique. | Jie LIN Yi DAI Ya-nan GUO Hai-rong XU Xiao-chang WANG | 2012 | Journal of Zhejiang University-Science B(Biomedicine & Biotechnology)2012,13,12: | 40 |
| 18 | Chinese deserts and sand fields in Last Glacial Maximum and Holocene Optimum显示文摘The Last Glacial Maximum (LGM, c. 26-16 ka) and the Holocene Optimum (HO, c. 9-5 ka) were characterized by cold-dry and warm-wet climates respectively in the recently geological Earth. How Chinese deserts and sand fields responded to these distinctive climatic changes is still not clear, however. To reconstruct environments of the deserts and sand fields during the LGM and HO is helpful to understand the forcing mechanisms of environment change in this arid region, and to test paleoclimatic modeling results. Through our long-term field and laboratory investigations, 400 optically stimulated luminescence (OSL) ages and more than 100 depositional records in the Chinese deserts and sand fields were obtained; on the basis of these data, we reconstruct spatial distributions of the deserts and sand fields during the LGM and HO. Our results show that the sand fields of Mu Us, Hunshandake, Horqin and Hulun Buir in northern and northeastern China had expanded 25%, 37%, 38% and 270%, respectively, during the LGM; the sand fields of Gonghe in the northeastern Qinghai-Tibetan Plateau had expanded 20%, and the deserts of Badain Jaran, Tengger in central northern China had expanded 39% and 29% separately during the LGM; the deserts of Taklimakan, Gurbantünggüt and Kumtag in northwestern China had expanded 10%-20% respectively, compared to their modern areas. On the other hand, all of the sand fields were nearly completely covered by vegetation during the HO; the deserts in northwestern and central northern China were reduced by around 5%-20% in area during this time. Lakes in this arid region were probably expanded during the HO but this conclusion needs more investigation. Compared with the geological distributions of deserts and sand fields, human activity has clearly changed (expanded) the area of active sand dunes at the present time. Our observations show that environmental conditions of Chinese deserts and sand fields are controlled by regional climate together with human activity. | LU HuaYu YI ShuangWen XU ZhiWei ZHOU YaLi ZENG Lin ZHU FangYing FENG Han DONG LiNa ZHUO HaiXin YU KaiFeng MASON Joseph WANG XiaoYong CHEN YingYong LU Qi WU Bo DONG ZhiBao QU JianJun WANG XunMing GUO ZhengTang | 2013 | Chinese Science Bulletin2013,58,23: | 40 |
| 19 | Helicobacter pylori infection generated gastric cancer through p53-Rb tumor-suppressor system mutation and telomerase reactivation显示文摘AIM: To investigate the relationship between Helicobacterpylori (H. pylori) infection and the expressions of the p53,Rb, c-myc, bcl-2 and hTERT mRNA in a series of diseasesfrom chronic gastritis (CG), intestinal metaplasia type Ⅰ or Ⅱ(IMⅠ-Ⅱ), intestinal metaplasia type Ⅲ (IMⅢ), mild or modestdysplasia (DysⅠ-Ⅱ), severe dysplasia (DysⅢ) to gastric cancer(GC) and to elucidate the mechanism of gastriccarcinogenesis relating to H.pyloriinfection.METHODS: 272 cases between 1998 and 2001 wereavailable for the study including 42 cases of CG, 46 cases ofIMⅠ-Ⅱ, 25 cases of IMⅢ, 48 cases of DysⅠ-Ⅱ, 27 cases ofDysⅢ, 84 cases of GC.-H. pyloriinfection and the expressionsof p53, Rb, c-myc, bcl-2 were detected by means ofstreptavidin-peroxidase (SP) immunohistochemical method.HTERT mRNA was detected byin situ hybridization(ISH).RESULTS: The expressions of p53, Rb, c-myc, hTERT mRNAand bcl-2 were higher in the GC than in CG, IN, Dys. Theexpression of c-myc was higher in IMⅢ with-H.pyloriinfection(10/16) than that without infection (1/9) and the positive ratein DysⅠ-Ⅱ and DysⅢ with-H.pyloriinfection was 18/30 and 13/17, respectively, higher than that without infection (4/18 and3/10, respectively). In our experiment mutated p53 had noassociation with H.pyloriinfection, theexpression of Rb wasassociated with-H. pyloriinfection in GC, but the p53-Rb tumor-suppressor system abnormal in DysⅠ-Ⅱ cases, DysⅢⅡ and GCcases with H. pyloriinfection was 21/30, 15/17 and 48/48respecively, higher than non-infection groups (4/18, 3/10, 28/36). Furthermore the level of hTERT mRNA in GC with H. pyloriinfection (47/48) was higher than that without infection (30/36), however the relationship between bcl-2 and H. pyloriwasonly in IMⅢ. C-myc had a close association with hTERT mRNAin DysⅢ and GC (P=0.0 253,0.0 305 respectively).CONCLUSION: In the gastric carcinogenesis, H. pylorimightcause the severe imbalance of proliferation and apoptosisin the precancerous lesions (IMⅢ and GysⅢ) first, leadingto p53-Rb tumor-suppressor system mutation and telomerasereactivation, and finally causes gastric cancer. | Jing Lan Yong-Yan Xiong Yi-Xian Lin Bi-Cheng Wang Ling-Ling Gong Hui-Sen Xu Guang-Song Guo Department of Pathology,Zhongnan Hospital,Wuhan University,Wuhan city 430071,Hubei Province,China | 2003 | World Journal of Gastroenterology2003,9,1: | 39 |
| 20 | Single-cell multi-omics sequencing of mouse early embryos and embryonic stem cells显示文摘定序技术的单个房间的 epigenome 最近被开发了。然而,在一个单个房间定序的 epigenome 的不同的层的联合还没被完成了。这里,我们开发了定序能分析染色质的技术(单个房间的 COOL-seq ) 的单个房间的 multi-omics 放的 state/nucleosome, DNA methylation,拷贝数字变化和 ploidy 同时从一样的单个哺乳动物的房间。我们使用了这个方法在老鼠 preimplantation 胚胎分析染色质状态和 DNA methylation 的 reprogramming。我们发现了那在以内 < 授精的 12 h,每个单个房间和母亲、父亲的染色体的快速、全球的 reprogramming 经历全球染色体 demethylation 到一个高度打开的染色质状态。这被减少的坦诚在迟了的接合子阶段以后跟随。而且,从迟了的接合子上演到 4 房间,剩余 DNA methylation 优先地在各单个的分裂球在父亲的等位基因的 intergenic 区域和母亲的等位基因的 intragenic 区域上被保存。然而,染色质可接近性在在从迟了的接合子的每个单个房间的父亲、母亲的等位基因之间是类似的到胚囊阶段。几个 pluripotency 管理者的有约束力的主题在远侧的 nucleosome 被充实弄空的区域从象 2 房间阶段一样早。这显示如此的目标基因的 cis 规章的元素从 2 房间阶段被告知到一个开的状态向前,在 pluripotency 最后在胚囊的 ICM 被建立以前,渴望。基因可以被分类进同类地开,同类地关门了并且分叉的状态基于他们在单个房间之中的倡导者区域的染色质可接近性。这能在 preimplantation 开发期间被跟踪到逐步的转变。我们的学习在早老鼠胚胎在单个底的分辨率提供染色体规模染色质状态和 DNA methylation 动力学的第一单个房间、父母的等位基因特定的分析并且提供新卓见进异构还高度在这个过程期间订了 epigenomic reprogramming 的特征。 | Fan Guo Lin Li Jingyun Li Xinglong Wu Boqiang Hu Ping Zhu Lu Wen Fuchou Tang | 2017 | Cell Research2017,27,8: | 34 |
