1冠状动脉内影像学临床应用专家共识(第一部分):对冠状动脉介入治疗的指导与优化显示文摘欧洲心血管介入协会(EAPCI)专家组系统总结了血管内超声(IVUS)和光学相干断层成像(OCT)这两种血管内影像学检查临床应用指征的现有证据,提供了关于IVUS和OCT指导经皮冠状动脉介入治疗(PCI)的应用价值,并明确了最可能从腔内影像学指导的介入治疗中获得临床收益的患者或病变类型,同时详细论述了PCI前如何使用IVUS或OCT优化支架尺寸(支架长度和直径)和手术策略的选择。此外,专家推荐对支架失败(支架内再狭窄或支架内血栓形成)的患者应常规进行冠状动脉内影像学检查,并首选OCT。最后,重点论述了IVUS和OCT在指导PCI和评估支架失败两个方面的优势和局限性,并对未来需要深入研究的领域进行了展望。Lorenz Raber Gary S Mintz Konstantinos C Koskinas Thomas W Johnson Niels R Holm Yoshinubo Onuma Maria D Radu Michael Joner Bo Yu Haibo Jia Nicolas Meneveau Jose M.de la Torre Hemandez Javier Escaned Jonathan Hill Francesco Prati Antonio Colombo Carlo di Mario Evelyn Regar Davide Capodanno William Wijns Robert A Byme Giulio Guagliumi 2019中华心血管病杂志2019,47,1:17
2Microbiota modification by probiotic supplementation reduces colitis associated colon cancer in mice显示文摘AIM To investigate the effect of probiotic supplementation during the development of an experimental model of colitis associated colon cancer(CAC). METHODS C57 BL/6 mice received an intraperitoneal injection of azoxymethane(10 mg/kg), followed by three cycles of sodium dextran sulphate diluted in water(5% w/v). Probiotic group received daily a mixture of Lactobacillus acidophilus, Lactobacil us rhamnosus and Bifidobacterium bifidum. Microbiota composition was assessed by 16 Sr RNA Illumina Hi Seq sequencing. Colon samples were collected for histological analysis. Tumor cytokines was assessed by Real Time-PCR(Polymerase Chain Reaction); and serum cytokines by Multiplex assay. All tests were two-sided. The level of significance was set at P < 0.05. Graphs were generated and statistical analysis performed using the software Graph Pad Prism 5.0. The project was approved by the institutional review board committee. RESULTS At day 60 after azoxymethane injection, the mean number of tumours in the probiotic group was 40% lower than that in the control group, and the probiotic group exhibited tumours of smaller size(< 2 mm)(P < 0.05). There was no difference in richness and diversity between groups. However, there was a significant difference in beta diversity in the multidimensional scaling analysis. The abundance of the genera Lactobacillus, Bifidobacterium, Allobaculum, Clostridium XI and Clostridium XVⅢ increased in the probiotic group(P < 0.05). The microbial change was accompanied by reduced colitis, demonstrated by a 46% reduction in the colon inflammatory index; reduced expression of the serum chemokines RANTES and Eotaxin; decreased p-IKK and TNF-α and increased IL-10 expression in the colon. CONCLUSION Our results suggest a potential chemopreventive effect of probiotic on CAC. Probiotic supplementation changes microbiota structure and regulates the inflammatory response, reducing colitis and preventing CAC.Maria Carolina S Mendes Daiane SM Paulino Sandra R Brambilla Juliana A Camargo Gabriela F Persinoti José Barreto C Carvalheira 2018World Journal of Gastroenterology2018,24,18:17
3Phase angle obtained by bioelectrical impedance analysis independently predicts mortality in patients with cirrhosis显示文摘AIM To evaluate the prognostic value of the phase angle(PA)obtained from bioelectrical impedance analysis(BIA) for mortality prediction in patients with cirrhosis. METHODS In total, 134 male cirrhotic patients prospectively completed clinical evaluations and nutritional assessment by BIA to obtain PAs during a 36-mo follow-up period. Mortality risk was analyzed by applying the PA cutoff point recently proposed as a malnutrition marker(PA ≤ 4.9°) in Kaplan-Meier curves and multivariate Cox regression models. RESULTS The patients were divided into two groups according to the PA cutoff value(PA > 4.9°, n = 73; PA ≤ 4.9°, n = 61). Weight, height, and body mass index were similar in both groups, but patients with PAs > 4.9° were younger and had higher mid-arm muscle circumference, albumin, and handgrip-strength values and lower severe ascites and encephalopathy incidences, interleukin(IL)-6/IL-10 ratios and C-reactive protein levels than did patients with PAs ≤ 4.9°(P ≤ 0.05). Forty-eight(35.80%) patients died due to cirrhosis, with a median of 18 mo(interquartile range, 3.3-25.6 mo) follow-up until death. Thirty-one(64.60%) of these patients were from the PA ≤ 4.9° group. PA ≤ 4.9° significantly and independently affected the mortality model adjusted for Model for End-Stage Liver Disease score and age(hazard ratio = 2.05, 95%CI: 1.11-3.77, P = 0.021). In addition, Kaplan-Meier curves showed that patients with PAs ≤ 4.9° were significantly more likely to die. CONCLUSION In male patients with cirrhosis, the PA ≤ 4.9° cutoff was associated independently with mortality and identified patients with worse metabolic, nutritional, and disease progression profiles. The PA may be a useful and reliable bedside tool to evaluate prognosis in cirrhosis.Giliane Belarmino Maria Cristina Gonzalez Raquel S Torrinhas Priscila Sala Wellington Andraus Luiz Augusto Carneiro D'Albuquerque Rosa Maria R Pereira Valéria F Caparbo Graziela R Ravacci Lucas Damiani Steven B Heymsfield Dan L Waitzberg 2017World Journal of Hepatology2017,9,7:11

7Pericytes synthesize renin显示文摘AIM: To investigate renin expression in pericytes during normal kidney development and after deletion of angiotensinogen, the precursor for all angiotensins.METHODS: We examined the distribution of renin expressing cells by immunoshistochemistry in the interstitial compartment of wild type(WT) and angiotensinogen deficient(AGT-/-) mice at different developmental stages from embryonic day 18(E18: WT, n = 4; AGT-/-, n = 5) and at day 1(P1: WT, n = 5; AGT-/-, n = 5), 5(P5: WT, n = 7; AGT-/-, n = 8), 10(P10: WT, n = 3; AGT-/-, n = 5), 21(P21: WT, n = 7; AGT-/-, n = 5), 45(P45: WT, n = 3; AGT-/-, n = 3), and 70(P70: WT, n = 2; AGT-/-, n = 2) of postnatal life. We quantified the number of pericytes positive for renin at all the developmental stages mentioned above and comparedthe results of AGT-/- mice to their WT counterparts.RESULTS: In WT mice, renal interstitial pericytes synthesize renin in early life supporting a lineage relationship with renin cells in the vasculature. The number of pericytes positive for renin per area of 0.32 mm2(density) in WT mice was maintained from fetal life till weaning age(E18 = 4.25 ± 0.63, P1 = 3.75 ± 0.48, P5 = 3.75 ± 0.48, P10 = 4 ± 0.71, P21 = 3.8 ± 0.58) and markedly decreased in adult life(P45 = 1.2 ± 0.37, P70 = 0.8 ± 0.20). On the other hand, in AGT-/- mice the density of pericytes expressing renin was not significantly different from WT mice at E18 and P1: E18 = 5.75 ± 0.50 vs 4.25 ± 0.63(P = 0.106), P1 = 9.25 ± 3.50 vs 3.75 ± 0.48(P = 0.175) but significantly increased from P5 till P70: P5 = 38.25 ± 5 vs 3.75 ± 0.48(P = 0.0004), P10 = 173 ± 7.50 vs 4 ± 0.70(P = 5.24567 × 10-7), P21 = 83 ± 6.70 vs 3.8 ± 0.58(P = 2.97358 × 10-6), P45 = 49 ± 3.50 vs 1.2 ± 0.37(P = 8.18274 x 10-7) and P70 = 17.8 ± 2.30 vs 0.8 ± 0.20(P = 3.51151 × 10-5). The AGT-/- mice showed a marked increase in the number of pericytes per field studied starting from P5, reaching its peak at P10, and then a gradually decreasing until P70. CONCLUSION: Interstitial pericytes synthesize renin during development and the number of renin-expressing pericytes increases in response to a homeostatic threat imposed early in life such as lack of angiotensinogen.Alison C Berg Catalina Chernavvsky-Sequeira Jennifer Lindsey R Ariel Gomez Maria Luisa S Sequeira-Lopez 2013World Journal of Nephrology2013,2,1:2

20Multiplexed Biosensing Diagnostic Platforms Detecting Autoantibodies to Tumor-Associated Antigens from Exosomes Released by CRC Cells and Tissue Samples Showed High Diagnostic Ability for Colorectal Cancer显示文摘Colorectal cancer(CRC)is the second leading cause of cancer-related death worldwide.The five-year survival rate of CRC patients depends on the stage at diagnosis,being higher than 80%when CRC is diagnosed in the early stages but lower than 10%when CRC is diagnosed in advanced stages.Autoantibodies against specific CRC autoantigens(tumor-associated antigens(TAAs))in the sera of patients have been widely demonstrated to aid in early diagnosis.Thus,we herein aim to identify autoantigens target of autoantibodies specific to CRC that possess a significant ability to discriminate between CRC patients and healthy individuals by means of liquid biopsy.To that end,we examined the protein content of the exosomes released by five CRC cell lines and tissue samples from CRC patients by means of immunoprecipitation coupled with mass spectrometry analysis.A total of 103 proteins were identified as potential autoantigens specific to CRC.After bioinformatics and meta-analysis,we selected 15 proteins that are more likely to be actual CRC autoantigens in order to evaluate their role in CRC prognosis by Western blot(WB)and immunohistochemistry(IHC).We found dysregulation at the protein level for 11 of these proteins in both tissue and plasma exosome samples from patients,along with an association of nine of these proteins with CRC prognosis.After validation,all but one showed a statistically significant high diagnostic ability to distinguish CRC patients and individuals with premalignant lesions from healthy individuals,either by luminescence Halotag-based beads,or by a multiplexed biosensing platform involving the use of magnetic microcarriers as solid support modified with covalently immobilized Halotag fusion proteins constructed for CRC detection.Taken together,our results highlight the usefulness of the approach defined here to identify the TAAs specific to chronic diseases;they also demonstrate that the measurement of autoantibody levels in plasma against the TAAs identified here could be integrated into a point-of-care(POC)device for CRC detection with high diagnostic ability.Ana Montero-Calle Itziar Aranguren-Abeigon María Garranzo-Asensio Carmen Poves María Jesús Fernández-Aceñero Javier Martínez-Useros Rodrigo Sanz Jana Dziaková Javier Rodriguez-Cobos Guillermo Solís-Fernández Eloy Povedano Maria Gamella Rebeca Magnolia Torrente-Rodríguez Miren Alonso-Navarro Vivian de los Ríos J.Ignacio Casal Gemma Domínguez Ana Guzman-Aranguez Alberto Peláez-García JoséManuel Pingarrón Susana Campuzano Rodrigo Barderas 2021Engineering2021,7,10:1
