2Osteopontin as potential biomarker and therapeutic target in gastric and liver cancers显示文摘Gastric cancer and liver cancer are among the most common malignancies and the leading causes of death worldwide,due to late detection and high recurrence rates.Today,these cancers have a heavy socioeconomic burden,for which a full understanding of their pathophysiological features is warranted to search for promising biomarkers and therapeutic targets.Osteopontin (OPN) is overexpressed in most patients with gastric and liver cancers.Over the past decade,emerging evidence has revealed a correlation of OPN level and clinicopathological features and prognosis in gastric and liver cancers,indicating its potential as an independent prognostic indicator in such patients.Functional studies have verified the potential of OPN knockdown as a therapeutic approach in vitro and in vivo .Furthermore,OPN mediates multifaceted roles in the interaction between cancer cells and the tumor microenvironment,in which many details need further exploration.OPN signaling results in various functions,including prevention of apoptosis,modulation of angiogenesis,malfunction of tumor-associated macrophages,degradation of extracellular matrix,activation of phosphoinositide 3-kinase-Akt and nuclear factor-κB pathways,which lead to tumor formation and progression,particularly in gastric and liver cancers.This editorial aims to review recent findings on alteration in OPN expression and its clinicopathological associations with tumor progression,its potential as a therapeutic target,and putative mechanisms in gastric and liver cancers.Better understanding of the implications of OPN in tumorigenesis might facilitate development of therapeutic regimens to benefit patients with these deadly malignancies.Dong-Xing Cao Zhi-Jie Li Xiao-Ou Jiang Yick Liang Lum Ester Khin Nikki P Lee Guo-Hao Wu John M Luk 2012World Journal of Gastroenterology2012,18,30:29
3成年大鼠睾丸经EDs处理后再生睾丸间质细胞基因图谱的改变显示文摘成年睾丸间质细胞(ALC)是睾丸中产生雄激素的唯一内分泌细胞,只占有睾丸细胞的1%-5%。大鼠睾丸中的睾丸间质细胞被EDs去除后能够再生。本研究中,我们主要研究了大鼠睾丸经EDS处理后睾丸间质细胞再生及基因的变化图谱。EDS处理后7、21、35、90天后分析血清中睾酮、睾丸基因图谱和一些类固醇生成相关的蛋白变化情况。EDS处理后第7天睾丸中睾酮水平几乎检测不到,然后开始恢复。处理后7天,81个基因下调2倍或者更多,其中48个基因检测不到,包括类固醇合成通路中的蛋白Star、Scarbl、Cypllal、Cypl7al、Hsd3bl、CyplblICyp2al。这些基因在21天开始表达增多,到90天已经完全恢复到正常水平。89个基因上调2倍或者更高,nPkib。这些上调的基因到90天恢复正常;其中Cyp2al直到35天才开始恢复,表明这个基因只在成年睾丸间质细胞中表达,不在前体细胞中表达。qPCR,Westernblot、半定量免疫组织染色检测了随机抽取的基因和蛋白确认其变化情况。Yu-Fei Zhang Kai-Ming Yuan Yong Liang Yan-Hui Chu Qing-Quan Lian Yu-Fei Ge Wei Zhen Chantal M Sottas Zhi-Jian Su Ren-Shan Ge 2015Asian Journal of Andrology2015,17,2:5
4Survival factors after resection of small hepatocellular carcinoma显示文摘Early resection of hepatocellular carcinoma is a key measure to prolong the survival of patients. This study was designed to summarize our experience in surgical resection of small hepatocellular carcinoma (HCC), and to analyze the factors influencing the postoperative survival of patients. METHODS:The clinicopathologic data of 105 patients with small HCC after resection from 1986 through 2003 were analyzed ; the patients had been followed up for more than half a year (median 33 months). Nine clinicopathologic factors, preoperative α-fetoprotein (AFP) level, liver cirrhosis, Child-Pugh score, tumor size (>2cm vs.≤2 cm) and number (single vs. multiple), capsule formation, portal vein tumor thrombi (PVTT), Edmondson tumor grade and surgical method, were analyzed by the log-rank test and the Cox proportional harzards model analysis. RESULTS:The cumulative 1-,3- and 5-year survival rates after the operation were 86.5%, 70.3% and 55.2%, respectively, and the 1-, 3- and 5-year disease-free survival rates were 78%, 58. 9% and 45. 6%, respectively. One patient died from esophagogastric varices hemorrhage in 2 weeks after reoperation. Thirty-six patients had intrahepatic recurrence or metastasis postoperatively and 34 patients died. The Kaplan-Meier method and the Cox proportional harzards model analysis indicated that poor Child-Pugh score, tumor more than 2 cm in diameter, PVTT and multiple lesions (including satellitic lesions) were adverse factors affecting postoperative survival. The Cox proportional harzards model analysis indicated that tumor size, PVTT and multiple lesions were the factors influencing postoperative disease-free survival. CONCLUSIONS:Limited hepatectomy with a margin more than 1 cm is an appropriate surgical approach. Adverse preoperative Child-Pugh score and postoperative intrahepatic recurrences are the main factors leading to the death of patients with small HCC.Departments of Surgical Oncology (Wu FS, Zhao WH, Ma ZM, Teng LS and Wang M) and General Surgery ( Liang TB and Zheng SS) , First Affiliated Hospital, Zhejiang University School of Medicine, Hangzhou 310003, China 2005Hepatobiliary & Pancreatic Diseases International2005,4,3:5
5Clinicopathological parameters predicting recurrence of pT1N0 esophageal squamous cell carcinoma显示文摘AIM To identify the clinicopathological characteristics of pT1 N0 esophageal squamous cell carcinoma(ESCC) that are associated with tumor recurrence. METHODS We reviewed 216 pT1 N0 thoracic ESCC cases who underwent esophagectomy and thoracoabdominal two-field lymphadenectomy without preoperative chemoradiotherapy. After excluding those cases with clinical follow-up recorded fewer than 3 mo and those who died within 3 mo of surgery, we included 199 cases in the current analysis. Overall survival and recurrencefree survival were assessed by the Kaplan-Meier method, and clinicopathological characteristics associated with any recurrence or distant recurrence were evaluated using univariate and multivariate Cox proportional hazards models. Early recurrence(≤ 24 mo) and correlated parameters were assessed using univariate and multivariate logistic regression models.RESULTS Forty-seven(24%) patients had a recurrence at 3 to 178(median, 33) mo. The 5-year recurrence-free survival rate was 80.7%. None of 13 asymptomatic cases had a recurrence. Preoperative clinical symptoms, upper thoracic location, ulcerative or intraluminal mass macroscopic tumor type, tumor invasion depth level, basaloid histology, angiolymphatic invasion, tumor thickness, submucosal invasion thickness, diameter of the largest single tongue of invasion, and complete negative aberrant p53 expression were significantly related to tumor recurrence and/or recurrence-free survival. Upper thoracic tumor location, angiolymphatic invasion, and submucosal invasion thickness were independent predictors of tumor recurrence(Hazard ratios = 3.26, 3.42, and 2.06, P < 0.001, P < 0.001, and P = 0.002, respectively), and a nomogram for predicting recurrence-free survival with these three predictors was constructed. Upper thoracic tumor location and angiolymphatic invasion were independent predictors of distant recurrence. Upper thoracic tumor location, angiolymphatic invasion, submucosal invasion thickness, and diameter of the largest single tongue of invasion were independent predictors of early recurrence.CONCLUSION These results should be useful for designing optimal individual follow-up and therapy for patients with T1 N0 ESCC.Li-Yan Xue Xiu-Min Qin Yong Liu Jun Liang Hua Lin Xue-Min Xue Shuang-Mei Zou Mo-Yan Zhang Bai-Hua Zhang Zhou-Guang Hui Zi-Tong Zhao Li-Qun Ren Yue-Ming Zhang Xiu-Yun Liu Yan-Ling Yuan Jian-Ming Ying Shu-Geng Gao Yong-Mei Song Gui-Qi Wang Sanford M Dawsey Ning Lu 2018World Journal of Gastroenterology2018,24,45:4
6Macro-regenerative nodules in biliary atresia:CT/MRI findings and their pathological relations显示文摘AIM: To describe the radiological findings of a macro-regenerative nodule (MRN) in the liver of pre-transplantation biliary atresia (BA) patients and to correlate it with histological findings. METHODS: Between August 1990 and November 2007, 144 BA patients underwent liver transplantation (LT) at our institution. The pre-transplantation computer tomograghy (CT) and magnetic resonance imaging (MRI) findings were reviewed and correlated with the post-transplantation pathological findings. RESULTS: Nine tumor lesions in 7 patients were diagnosed in explanted livers. The post-transplantation pathological findings showed that all the lesions were MRNs without malignant features. No small nodule was detected by either MRI or CT. Of the 8 detectable lesions, 6 (75%) were in the central part of the liver, 5 (63%) were larger than 5 cm, 5 (63%) had intra- tumor tubular structures, 3 (38%) showed enhancing fibrous septa, 3 (38%) had arterial enhancement in CT, one (13%) showed enhancement in MRI, and one (13%) had internal calcifications. CONCLUSION: Although varied in radiological appearance, MRN can be differentiated from hepatocellular carcinoma (HCC) in most of BA patients awaiting LT. The presence of an arterial-enhancingnodule does not imply that LT is withheld solely on the basis of presumed malignancy by imaging studies. Liver biopsy may be required in aid of diagnostic imaging to exclude malignancy.Jiun-Lung Liang Yu-Fan Cheng Allan M Concejero Tung-Liang Huang Tai-Yi Chen Leo Leung-Chit Tsang Hsin-You Ou 2008World Journal of Gastroenterology2008,14,28:4
7Shift current bulk photovoltaic effect in polar materials—hybrid and oxide perovskites and beyond显示文摘The bulk photovoltaic effect(BPVE)refers to the generation of a steady photocurrent and above-bandgap photovoltage in a single-phase homogeneous material lacking inversion symmetry.The mechanism of BPVE is decidedly different from the typical p-n junction-based photovoltaic mechanism in heterogeneous materials.Recently,there has been renewed interest in ferroelectric materials for solar energy conversion,inspired by the discovery of above-bandgap photovoltages in ferroelectrics,the invention of low bandgap ferroelectric materials and the rapidly improving power conversion efficiency of metal halide perovskites.However,as long as the nature of the BPVE and its dependence on composition and structure remain poorly understood,materials engineering and the realisation of its true potential will be hampered.In this review article,we survey the history,development and recent progress in understanding the mechanisms of BPVE,with a focus on the shift current mechanism,an intrinsic BPVE that is universal to all materials lacking inversion symmetry.In addition to explaining the theory of shift current,materials design opportunities and challenges will be discussed for future applications of the BPVE.Liang Z Tan Fan Zheng Steve M Young Fenggong Wang Shi Liu Andrew M Rappe 2016npj Computational Materials2016,,1:4
8Differently sized cuckoos pose different threats to hosts显示文摘Hole-nesting tits Parus spp.have been classified as'unsuitable'hosts for cuckoo parasitism because cuckoos cannot enter a cavity if the entrance is too small.However,Chinese tits could re-ject alien eggs and egg ejection rate increased with the local diversity of parasitic cuckoo species.Antiparasitic behavior among Chinese tits may have evolved due to greater size variation among sympatric cuckoo species.This raises the question of whether differently sized parasitic cuckoos pose different threats to Chinese tits.A green-backed tit Parus monticolus population that is sym-patric with Asian emerald cuckoo Chrysococcyx maculatus(eme-cuckoo,small-sized parasite)and common cuckoo Cuculus canorus(com-cuckoo,large-sized parasite),and a cinereous tit P.cinereus population that is only sympatric with com-cuckoo were chosen as study organisms.We observed behavioral response and recorded alarm calls of the 2 tit species to eme-cuckoo,com-cuckoo,chipmunk Tamias sibiricus(a nest predator)and dove Streptopelia orientalis(a harm-less control),and subsequently played back alarm calls to conspecific incubating females.In dummy experiments,both tit species performed intense response behavior to chipmunk,but rarely responded strongly to the 3 avian species.In playback experiments,both tit species responded strongly to conspecific chipmunk alarm calls,but rarely responded to dove alarm calls.The inten-sity of response of incubating female green-backed tits to eme-cuckoo and com-cuckoo alarm calls were similar to that of chipmunk alarm calls,while the intensity to eme-cuckoo alarm calls was higher than the intensity to dove alarm calls which was similar to that of com-cuckoo alarm calls.In contrast,few female cinereous tits responded to eme-cuckoo and com-cuckoo alarm calls.These findings indicated that the threat level of eme-cuckoo was slightly greater than that of com-cuckoo for sympatric green-backed tits,but not for allopatric cinereous tits.Jiangping YU Mingju E Wei SUN Wei LIANG Haitao WANG Anders Pape MΦLLER 2020Current Zoology2020,66,3:4

10Adaptation or ecological trap? Altered nest-site selection by Reed Parrotbills after an extreme flood显示文摘Background:Floods and other extreme events have disastrous effects on wetland breeding birds.However,such events and their consequences are difficult to study due to their rarity and unpredictable occurrence.Methods:Here we compared nest-sites chosen by Reed Parrotbills(Paradoxornis heudei) during June-August 2016 in Yongnianwa Wetlands,Hebei Province,China,before and after an extreme flooding event.Results:Twenty-three nests were identified before and 13 new nests after the flood.There was no significant difference in most nest-site characteristics,such as distance from the road,height of the reeds in which nests were built,or nest volume before or after the flood.However,nests after the flood were located significantly higher in the vegetation compared to before the flood(mean ± SE:1.17 ± 0.13 m vs.0.75 ± 0.26 m,p < 0.01).However,predation rate also increased significantly after the flood(67% vs.25%,p = 0.030).Conclusions:Our results suggested that Reed Parrotbills demonstrated behavioral plasticity in their nest-site selection.Thus,they appeared to increase the height of their nests in response to the drastically changing water levels in reed wetlands,to reduce the likelihood that their nests would be submerged again by flooding.However,predation rate also increased significantly after the flood,suggesting that the change in nest height to combat the threat of flooding made the nests more susceptible to other threats,such as predation.Animals' response to rare climatic events,such as flooding,may produce ecological traps if they make the animals more susceptible to other kinds of threats they are more likely to continue to encounter.Laikun Ma Jianwei Zhang Jianping Liu Canchao Yang Wei Liang Anders Pape M?ller 2019Avian Research2019,10,1:3
11中国荷斯坦奶牛跛行和飞节损伤的风险因素分析显示文摘为了评估散栏牧场高产奶牛跛行率、飞节损伤与饲养管理、牧场设计之间的相关性,收集了中国34个大中型牧场高产牛群管理和卧床设计数据,如卧床设计、垫料类型和挤奶程序等。对每个圈的所有奶牛进行行走评分(1~5分)和飞节评分(1~3分)。其中行走评分大于等于3分定义为临床跛行,大于等于4分定义为严重跛行;飞节损伤大于等于2分为轻微损伤,3分为严重损伤。中国大中型牧场临床跛行率和严重跛行率分别为(31±12)%(分布于7%~51%)和(10±6)%(分布于0%~27%)。飞节轻微损伤率和严重损伤率分别为(40±20)%(分布于6%~95%)和(5±9)%(分布于0%~50%)。临床跛行率和严重跛行率与牧场的规模有显著相关性。随着牧场规模的增大,临床跛行和严重跛行有降低的趋势,每增加100头牛,临床跛行率降低(0.35±0.09)%,严重跛行率降低(0.15±0.06)%。牧场的新旧程度也显著影响跛行率,尤其是大于9年的牧场跛行率和严重跛行率明显升高。牧场的规模和新旧程度在引起临床跛行和严重跛行的因素中占49%和30%的作用。深槽卧床可降低轻微飞节损伤和严重飞节损伤的发生率(分别降低20.9%和3.65%)。大于9年的牧场飞节轻微损伤率和严重损伤率分别提高16.68%和7.17%。这2个变量可影响飞节轻微损伤和飞节严重损伤的52%和58%。总之,牧场之间的跛行率和飞节损伤率变异很大。良好的卧床设计和管理有助于降低跛行率和飞节损伤率。王艳明 Chapinal N Liang Y Weary D M Wang Y 2015中国乳业2015,0,7:3

14纳米碳化钒强化TWIP钢加工硬化机制研究显示文摘弥散分布的纳米碳化钒颗粒能明显提高TWIP钢的屈服强度,但同时将在一定程度上降低加工硬化率。采用一个修正的物理模型来研究纳米碳化钒颗粒对一种实验室等级的FeMnC奥氏体TWIP钢加工硬化率的影响。试验发现在塑性变形过程中弥散分布的纳米碳化钒颗粒会加快位错累积速率,但也会降低孪晶形成速率。与不含析出相的TWIP钢相比,在小应变时含纳米碳化钒颗粒的TWIP钢加工硬化率较高,但随着应变量的增加其硬化率减小的速度高于不含析出相的TWIP钢,因此在高应变条件下含纳米碳化钒颗粒的TWIP显示出较低的钢加工硬化率。Liang ZY Huang M X Yen H W Scott C P 魏世同(翻译) 2014钢铁钒钛2014,35,1:3

19Association between big endothelin-1 and CHADS2/CHA2DS2-VASc scores in non-valvular atrial fibrillation显示文摘Background Endothelial function,as measured by big endothelin-1(ET-1),has been demonstrated to be useful in predicting adverse long-term events in patients with cardiovascular disease.Nevertheless,there are little data about the association between big ET-1 and thromboembolism risk in atrial fibrillation(AF).We aimed to investigate the relationship between big ET-1 and CHADS2/CHA2DS2-VASc scores used for evaluating thromboembolic risk in patients with non-valvular AF.Methods The study population consisted of 238 consecutive AF patients(67.6%with paroxysmal AF and 32.4%with persistent AF).The patients were divided into two groups(high-or low-intermediate risk group)based on CHADS2 and CHA2 DS2-VASc scores(score≥2 or<2,respectively).Clinical,laboratory,and echocardiographic parameters were evaluated,and the CHADS2/CHA2DS2-VASc scores were compared between groups.The association between big ET-1 levels and CHADS2/CHA2DS2-VASc score was assessed.Multivariate logistic regression analysis was performed to identify independent predictors of CHADS2/CHA2DS2-VASc scores.Results The high CHADS2/CHA2DS2-VASc score group had older age,higher big ET-1 levels,and enlarged left atrial diameter than the low CHADS2/CHA2DS2-VASc score group(P<0.05).Multiple logistic regression analysis revealed that big ET-1 level was an independent determinant of high CHADS2/CHA2DS2-VASc scores[odds ratio(OR)=2.545 and OR=3.816;both P<0.05].Conclusions Our study indicates that in non-valvular AF,big ET-1 was significantly correlated with CHADS2/CHA2DS2-VASc scores and an independent predictor of high CHADS2/CHA2DS2-VASc scores.Big ET-1 may serve as a useful marker for risk stratification in this setting.Li-Hui ZHENG Shang-Yu LIU Feng HU Er-Peng LIANG Ling-Min WU Hong-Lei WANG Ammar M Killu Yan YAO 2019Journal of Geriatric Cardiology2019,16,11:2
