1Dynamic changes of typeⅠ,Ⅲand N collagen synthesis and distribution of collagen-producing cells in carbon tetrachloride-induced rat liver fibrosis显示文摘AIM To find out the relationship between the gene transcription of different types ofprocollagen and the deposition of the relevant collagens in the liver tissue and to confirm the types of collagen producing cells in liverfibrogenesis.METHODS Dynamic changes of the expression of α1(Ⅰ ), α1 (Ⅲ ) and α1 (Ⅳ) procollagen mRNAand relevant collagens and the distribution ofcollagen producing cells during liver fibrogenesis of rat induced by CCl4 (20 weeks)were investigated with Northern blot analysis,in situ hybridization and immunohistochemicaltechniques.RESULTS The increased expression of α1 (Ⅲ)procollagen mRNA by Northern blot analysis was the most predominant one among the threemRNAs during fibrogenesis. However, theenhanced expression of al (Ⅳ) procollagenmRNA occurred very early while the expressionof α1 (Ⅰ) mRNA was not enhanced much until themiddle stage of the exPeriment. D6smin (Dm)positive hepatic stellate cells (HSCs) and fewmyofibroblasts (MFs) in and around the necrotic areas expressed α1 (Ⅰ), α1 (Ⅲ) and α1 (Ⅳ)procollagen mRNA signals detected by in situhybridization at the early stage of theexperiment. All the three procollagen mRNAsignals thereafter mainly localized in fibroblasts (Fbs) and MFs in fibrotic septa during the middle and late stages of fibrosis, which distributedparallel to the corresponding collagens detected by immunohistochemical study. ln addition, the endothelial cells of sinusoids and the small blood vessels within the septa also showed α1(Ⅳ) procollagen mRNA and type Ⅳ collagen expressionCONCLUSION It is considered that 'HSC-MF-Fb' effect cell system is the major cellularsource of collagen production in liver fibrosis, in which HSCs are collagen producing precursor cells in the early liver fibrogenesis, thereafter the synthesis of type Ⅰ, Ⅲ and Ⅳ collagens (Col Ⅰ, Col Ⅲ and Col Ⅳ) mainly derives fromMFs and Fbs, which play a very important role in the progress of liver fibrosis. The endothelialcells along sinusoids, as another source of Col Ⅳ production, might participate in the capillization of liver sinusoids.DU Wei-Dong ZHANG Yue-E ZHAl Wei-Rong and ZHOU Xiao-Mei(Department of Pathology, Shanghai Medical University, Shanghai200032, China)(National Laboratory for Oncogenes and Related Genes, ShanghaiCencer Institute)See invited commentary on page 388 1999World Journal of Gastroenterology1999,5,5:47
2慢性病儿童应激源应对方式及心理状态的研究显示文摘目的在治疗慢性病儿童的同时,了解患儿的应激源、应对方式及心理状态,对于帮助他(她)们更好地应对慢性病的挑战、适应慢性病的状态是非常有帮助的。该研究旨在了解我国慢性病儿童的应激源、应对方式、心理状态及其影响因素,为儿科工作者提供信息,为临床干预提供依据。方法对203名8~16岁慢性病儿童进行调查,采用半结构访谈方式了解其应激源,采用CODI自评应对方式量表、儿童焦虑性情绪障碍筛查表(SCARED)、儿童抑郁障碍自评量表(DSRSC)了解其应对方式及焦虑、抑郁状态。结果①患儿应激源主要包括学习、疾病治疗、日常生活、与同学/伙伴关系4个方面。②患儿最常采用的应对方式是'幻想',其次是'接受','负性情绪反应'使用率最少。③慢性病儿童焦虑、抑郁量表得分均高于常模。被调查者中,43.8%患儿存在焦虑障碍,30.0%存在抑郁障碍,26.1%同时存在焦虑和抑郁障碍。结论慢性病儿童应激源较多,虽然相对较多采用积极应对方式,但其焦虑障碍和抑郁障碍仍比较普遍而且严重,应引起关注。李杨 魏珉 Gayle PAGE Susan IMMELT 2008中国当代儿科杂志2008,10,3:29
3Otitis media with effusion in children: Pathophysiology, diagnosis, and treatment.A review显示文摘Otitis media with effusion(OME)is a frequent paediatric disorder.The condition is often asymptomatic,and so can easily be missed.However,OME can lead to hearing loss that impairs the child's language and behavioural development.The diagnosis is essentially clinical,and is based on otoscopy and(in some cases)tympanometry.Nasal endoscopy is only indicated in cases of unilateral OME or when obstructive adenoid hypertrophy is suspected.Otitis media with effusion is defined as the observation of middle-ear effusion at consultations three months apart.Hearing must be evaluated(using an age-appropriate audiometry technique)before and after treatment,so as not to miss another underlying cause of deafness(e.g.perception deafness).Craniofacial dysmorphism,respiratory allergy and gastro-oesophageal reflux all favour the development of OME.Although a certain number of medications(antibiotics,corticoids,antihistamines,mucokinetic agents,and nasal decongestants)can be used to treat OME,they are not reliably effective and rarely provide long-term relief.The benchmark treatment for OME is placement of tympanostomy tubes(TTs)and(in some cases)adjunct adenoidectomy.The TTs rapidly normalize hearing and effectively prevent the development of cholesteatoma in the middle ear.In contrast,TTs do not prevent progression towards tympanic atrophy or a retraction pocket.Adenoidectomy enhances the effectiveness of TTs.In children with adenoid hypertrophy,adenoidectomy is indicated before the age of 4 but can be performed later when OME is identified by nasal endoscopy.Children must be followed up until OME has disappeared completely,so that any complications are not missed.Pauline Vanneste Cyril Page 2019Journal of Otology2019,14,2:19
4Effect of a fermented milk containing Bifidobacterium lactis DN-173010 on Chinese constipated women显示文摘AIM: To investigate the effect of a fermented milk containing Bifidobacterium lactis DN-173010 and yogurt strains (BIO) on adult women with constipation in Beijing.METHODS: A total of 135 adult females with constipation were randomly allocated to consume for 2 wk either 100 g of the test fermented milk or 100 g of an acidified milk containing non-living bacteria (control).Stool frequency,defecation condition scores,stool consistency and food intake were recorded at baseline and after 1 and 2 wk in an intention-to-treat population of 126 subjects.In parallel,safety evaluation parameters were performed.RESULTS: At baseline,no differences were found between groups.Following consumption of test product,stool frequency was significantly increased after 1 wk (3.5 ± 1.5 vs 2.4 ± 0.6,P < 0.01) and 2 wk (4.1 ± 1.7 vs 2.4 ± 0.6,P < 0.01),vs baseline.Similarly,after 1 and 2 wk,of test product consumption,defecation condition (1.1 ± 0.9 vs 1.9 ± 1.2,P < 0.01 and 0.8 ± 1.0 vs 1.9 ± 1.2,P < 0.01,respectively) and stool consistency (1.0 ± 0.8 vs 1.5 ± 1.1,P < 0.01 and 0.6 ± 0.8 vs 1.5 ± 1.1,P < 0.01,respectively) were significantly improved.Compared with the control group,stool frequency was also significantly increased (3.5 ± 1.5 vs 2.5 ± 0.9,P < 0.01 and 4.1 ± 1.7 vs 2.6 ± 1.0,P < 0.01,respectively),and defecation condition (1.1 ± 0.9 vs 1.6 ± 1.1,P < 0.01 and 0.8 ± 1.0 vs 1.6 ± 1.1,P < 0.01,respectively) and stool consistency (1.0 ± 0.8 vs 1.4 ± 1.0,P < 0.05 and 0.6 ± 0.8 vs 1.3 ± 1.0,P < 0.01,respectively) significantly decreased after 1 and 2 wk of product consumption.During the same period,food intake did not change between the two groups,and safety parameters of the subjects were within normal ranges.CONCLUSION: This study suggests a beneficial effect of a fermented milk containing B.lactis DN-173010 on stool frequency,defecation condition and stool consistency in adult women with constipation constipated women after 1 and 2 wk of consumption.Yue-Xin Yang Mei He Gang Hu Jie Wei Philippe Pages Xian-Hua Yang Sophie Bourdu-Naturel 2008World Journal of Gastroenterology2008,14,40:18
5对慢性病患儿及其父母教育干预的效果研究显示文摘目的评价针对慢性病患儿及其父母的教育干预措施的效果,为临床建立系统的针对慢性病患儿及其父母的教育干预项目提供依据。方法 50名慢性病患儿和75名慢性病患儿父母为研究对象。干预组为2007年8月至2008年1月住院的患儿及其父母,对照组为2007年2月~7月住院的患儿及其父母。患儿入院2d后开始教育干预,内容包括疾病知识、自我管理、用药知识和应对技巧等。在患儿出院前1天、出院后3个月时评价两组患儿及患儿父母的知识水平、应激源、应对方式、心理状态及服药依从性。结果教育干预后,干预组患儿父母及患儿的知识问卷得分均高于对照组(P<0.01),应激源数均低于对照组(P<0.01,P<0.05);干预组患儿父母'通过咨询和交流获取信息'的积极应对方式的使用频率高于对照组(P<0.05);但两组患儿用药依从性差异无统计学意义(P>0.05)。结论教育干预可以提高慢性病患儿及父母疾病知识水平,减少患儿及父母的应激源数,使父母更多地采用积极的应对方式,但对改善患儿及父母的焦虑、抑郁状态无明显作用。李杨 魏珉 Gayle PAGE Susan IMMELT 鲁重美 2010中国当代儿科杂志2010,12,6:13
6慢性病患儿父母应激源、应对方式、心理状态及其影响因素的研究显示文摘目的了解慢性病患儿父母的应激源、应对方式、心理状态及其影响因素,为临床工作者提供信息,为临床干预提供依据。方法对280名慢性病儿童父母进行调查,采用半结构访谈方式了解其应激源,采用CHIP应对方式量表、Zung焦虑自评量表(SAS)和Zung抑郁自评量表(SDS)了解其应对方式、焦虑、抑郁状态。结果患儿父母应激源主要包括6个方面:患儿病情及身体状况、疾病治疗、经济方面、照顾患儿方面、角色功能及沟通交流。父母采用的积极应对方法比较局限,更多集中在为患儿寻求和维持更好的疾病治疗方面,而忽视了其自身的心理调节和寻求社会支持。58.6%的父母存在焦虑,56.8%存在抑郁,49.6%的父母同时存在焦虑和抑郁。父母应激源越多压力程度越大,采用积极应对方式的频率越少,焦虑和抑郁程度越重;良好的心理状态与其积极的应对方式呈正相关。结论慢性病患儿父母应激源较多,压力较大,对积极的应对方式的选择还比较局限,心理问题也较严重,应引起重视。李杨 魏珉 Gayle Page Susan Immelt 2010中华现代护理杂志2010,16,5:12
7Management of borderline and locally advanced pancreatic cancer:Where do we stand?显示文摘Many patients with pancreas cancer present with locally advanced pancreatic cancer(LAPC).The principle tools used for diagnosis and staging of LAPC include endoscopic ultrasound,axial imaging with computed tomography and magnetic resonance imaging,and diagnostic laparoscopy.The definition of resectability has historically been vague,as there is considerable debate and controversy as to the definition of LAPC.For the patient with LAPC,there is some level of involvement of the surrounding vascular structures,which include the superior mesenteric artery,celiac axis,hepatic artery,superior mesenteric vein,or portal vein.When feasible,most surgeons would recommend possible surgical resection for patients with borderline LAPC,with the goal of an R0 resection.For initially unresectable LAPC,neoadjuvant should be strongly considered.Specifically,these patients should be offered neoadjuvant therapy,and the tumor should be assessed for possible response and eventual resection.The efficacy of neoadjuvant therapy with this approach as a bridge to potential curative resection is broad,ranging from 3%-79%.The different modalities of neoadjuvant therapy include sin-gle or multi-agent chemotherapy combined with radiation,chemotherapy alone,and chemotherapy followed by chemotherapy with radiation.This review focuses on patients with LAPC and addresses recent advances and controversies in the field.Jin He Andrew J Page Matthew Weiss Christopher L Wolfgang Joseph M Herman Timothy M Pawlik 2014World Journal of Gastroenterology2014,20,9:11

14Fatty liver disease,an emerging etiology of hepatocellular carcinoma in Argentina显示文摘AIM To investigate any changing trends in the etiologies of hepatocellular carcinoma(HCC) in Argentina during the last years. METHODS A longitudinal cohort study was conducted by 14 regional hospitals starting in 2009 through 2016. All adult patients with newly diagnosed HCC either with pathology or imaging criteria were included. Patients were classified as presenting non-alcoholic fatty liver disease(NAFLD) either by histology or clinically, provided that all other etiologies of liver disease were ruled out, fatty liver was present on abdominal ultrasound and alcohol consumption was excluded. Complete follow-up was assessed in all included subjects since the date of HCC diagnosis until death or last medical visit.RESULTS A total of 708 consecutive adults with HCC were included. Six out of 14 hospitals were liver transplant centers(n = 484). The prevalence of diabetes mellitus was 27.7%. Overall, HCV was the main cause of liver disease related with HCC(37%) including cirrhotic and non-cirrhotic patients, followed by alcoholic liver disease 20.8%, NAFLD 11.4%, cryptogenic 9.6%, HBV 5.4% infection, cholestatic disease and autoimmune hepatitis 2.2%, and other causes 9.9%. A 6-fold increase in the percentage corresponding to NAFLDHCC was detected when the starting year, i.e., 2009 was compared to the last one, i.e., 2015(4.3% vs 25.6%; P < 0.0001). Accordingly, a higher prevalence of diabetes mellitus was present in NAFLD-HCC group 61.7% when compared to other than NAFLD-HCC 23.3%(P < 0.0001). Lower median AFP values at HCC diagnosis were observed between NAFLD-HCC and non-NAFLD groups(6.6 ng/m L vs 26 ng/m L; P = 0.02). Neither NAFLD nor other HCC etiologies were associated with higher mortality.CONCLUSION The growing incidence of NAFLD-HCC documented in the United States and Europe is also observed in Argentina, a confirmation with important Public Health implications.Federico Pinero Josefina Pages Sebastián Marciano Nora Fernández Jorge Silva Margarita Anders Alina Zerega Ezequiel Ridruejo Beatriz Ameigeiras Claudia D’Amico Luis Gaite Carla Bermúdez Manuel Cobos Carlos Rosales Gustavo Romero Lucas McCormack Virginia Reggiardo Luis Colombato Adrián Gadano Marcelo Silva 2018World Journal of Hepatology2018,10,1:4
15The next detectors for gravitational wave astronomy显示文摘This paper focuses on the next detectors for gravitational wave astronomy which will be required after the current ground based detectors have completed their initial observations, and probably achieved the first direct detection of gravitational waves. The next detectors will need to have greater sensitivity, while also enabling the world array of detectors to have improved angular resolution to allow localisation of signal sources. Sect. 1 of this paper begins by reviewing proposals for the next ground based detectors,and presents an analysis of the sensitivity of an 8 km armlength detector, which is proposed as a safe and cost-effective means to attain a 4-fold improvement in sensitivity. The scientific benefits of creating a pair of such detectors in China and Australia is emphasised. Sect. 2 of this paper discusses the high performance suspension systems for test masses that will be an essential component for future detectors, while sect. 3 discusses solutions to the problem of Newtonian noise which arise from fluctuations in gravity gradient forces acting on test masses. Such gravitational perturbations cannot be shielded, and set limits to low frequency sensitivity unless measured and suppressed. Sects. 4 and 5 address critical operational technologies that will be ongoing issues in future detectors. Sect. 4 addresses the design of thermal compensation systems needed in all high optical power interferometers operating at room temperature. Parametric instability control is addressed in sect. 5. Only recently proven to occur in Advanced LIGO, parametric instability phenomenon brings both risks and opportunities for future detectors. The path to future enhancements of detectors will come from quantum measurement technologies. Sect. 6 focuses on the use of optomechanical devices for obtaining enhanced sensitivity, while sect. 7 reviews a range of quantum measurement options.BLAIR David JU Li ZHAO ChunNong WEN LinQing MIAO HaiXing CAI RongGen GAO JiangRui LIN XueChun LIU Dong WU Ling-An ZHU ZongHong HAMMOND Giles PAIK Ho Jung FAFONE Viviana ROCCHI Alessio BLAIR Carl MA YiQiu QIN JiaYi PAGE Michael 2015Science China(Physics,Mechanics & Astronomy)2015,58,12:3
16Laser-induced graphene for bioelectronics and soft actuators显示文摘Laser-assisted process can enable facile,mask-free,large-area,inexpensive,customizable,and miniaturized patterning of laser-induced porous graphene(LIG)on versatile carbonaceous substrates(e.g.,polymers,wood,food,textiles)in a programmed manner at ambient conditions.Together with high tailorability of its porosity,morphology,composition,and electrical conductivity,LIG can find wide applications in emerging bioelectronics(e.g.,biophysical and biochemical sensing)and soft robots(e.g.,soft actuators).In this review paper,we first introduce the methods to make LIG on various carbonaceous substrates and then discuss its electrical,mechanical,and antibacterial properties and biocompatibility that are critical for applications in bioelectronics and soft robots.Next,we overview the recent studies of LIG-based biophysical(e.g.,strain,pressure,temperature,hydration,humidity,electrophysiological)sensors and biochemical(e.g.,gases,electrolytes,metabolites,pathogens,nucleic acids,immunology)sensors.The applications of LIG in flexible energy generators and photodetectors are also introduced.In addition,LIG-enabled soft actuators that can respond to chemicals,electricity,and light stimulus are overviewed.Finally,we briefly discuss the future challenges and opportunities of LIG fabrications and applications.Yadong Xu Qihui Fei Margaret Page Ganggang Zhao Yun Ling Dick Chen Zheng Yan 2021Nano Research2021,14,9:3
17Natural polyphenols effects on protein aggregates in Alzheimer's and Parkinson's prion-like diseases显示文摘Alzheimer's and Parkinson's diseases are the most common neurodegenerative diseases. They are characterized by protein aggregates and so can be considered as prion-like disease. The major components of these deposits are amyloid peptide and tau for Alzheimer's disease, α-synuclein and synphilin-1 for Parkinson's disease. Drugs currently proposed to treat these pathologies do not prevent neurodegenerative processes and are mainly symptomatic therapies. Molecules inducing inhibition of aggregation or disaggregation of these proteins could have beneficial effects, especially if they have other beneficial effects for these diseases. Thus, several natural polyphenols, which have antioxidative, anti-inflammatory and neuroprotective properties, have been largely studied, for their effects on protein aggregates found in these diseases, notably in vitro. In this article, we propose to review the significant papers concerning the role of polyphenols on aggregation and disaggregation of amyloid peptide, tau, α-synuclein, synphilin-1, suggesting that these compounds could be useful in the treatments in Alzheimer's and Parkinson's diseases.aline freyssin guylène page bernard fauconneau agnès rioux bilan 2018Neural Regeneration Research2018,13,6:3
