2Indocyanine green kinetics to assess liver function: Ready for a clinical dynamic assessment in major liver surgery?显示文摘Indocyanine green(ICG) kinetics(PDR/R15) used to quantitatively assess hepatic function in the perioperative period of major resective surgery and liver transplantation have been the object of an extensive, updated and critical review. New, non invasive bedside monitors(pulse dye densitometry technology) make this opportunity widely available in clinical practice. After having reviewed basic concepts of hepatic clearance, we analysed the most common indications ICG kinetic parameters have nowadays in clinical practice, focusing in particular on the diagnostic and prognostic role of PDR and R15 in the perioperative period of major liver surgery and liver transplantation. As recently pointed out, even if of extreme interest, ICG clearance parameters have still some limitations, to be considered when using these tests.Andrea De Gasperi Ernestina Mazza Manlio Prosperi 2016World Journal of Hepatology2016,8,7:22
3微波提取法对樱桃、猕猴桃和枸杞多糖特性的影响显示文摘微波提取是近年来发展迅速的天然产物提取技术之一。为考察微波提取对多糖得率、结构及生物学功能的影响,论文采用微波功率1000W和提取温度140℃,以不同提取时间5,10和20min分别对樱桃、猕猴桃和枸杞中多糖进行提取。结果表明,微波提取多糖的得率、相对分子质量和抗氧化性低于传统提取方法,随着微波提取时间延长,多糖相对分子质量逐步降低,但多糖得率与抗氧化性无显著变化;微波提取得到的多糖在单糖组成上与传统提取方法有一定的差异。该研究结果对应用微波提取水果多糖条件的选择及多糖品质控制有一定的参考价值。范会平 符锋 Giuseppe Mazza 胡小松 廖小军 2009农业工程学报2009,25,10:18
4Apparent diffusion coefficient by diffusion-weighted magnetic resonance imaging as a sole biomarker for staging and prognosis of gastric cancer显示文摘Objective:To investigate the role of apparent diffusion coefficient(ADC)from diffusion-weighted magnetic resonance imaging(DW-MRI)when applied to the 7th TNM classification in the staging and prognosis of gastric cancer(GC).Methods:Between October 2009 and May 2014,a total of 89 patients with non-metastatic,biopsy proven GC underwent 1.5T DW-MRI,and then treated with radical surgery.Tumor ADC was measured retrospectively and compared with final histology following the 7th TNM staging(local invasion,nodal involvement and according to the different groups—stage I,II and III).Kaplan-Meier curves were also generated.The follow-up period is updated to May 2016.Results:Median follow-up period was 33 months and 45/89(51%)deaths from GC were observed.ADC was significantly different both for local invasion and nodal involvement(P<0.001).Considering final histology as the reference standard,a preoperative ADC cut-off of 1.80×10–3 mm2/s could distinguish between stages I and II and an ADC value of≤1.36×10–3 mm2/s was associated with stage III(P<0.001).Kaplan-Meier curves demonstrated that the survival rates for the three prognostic groups were significantly different according to final histology and ADC cut-offs(P<0.001).Conclusions:ADC is different according to local invasion,nodal involvement and the 7th TNM stage groups for GC,representing a potential,additional prognostic biomarker.The addition of DW-MRI could aid in the staging and risk stratification of GC.Francesco Giganti Alessandro Ambrosi Damiano Chiari Elena Orsenigo Antonio Esposito Elena Mazza Luca Albarello Carlo Staudacher Alessandro Del Maschio Francesco De Cobelli 2017Chinese Journal of Cancer Research2017,29,2:15

8Computational Aspects of Dam Risk Analysis: Findings and Challenges显示文摘水电是一种清洁、可再生,且对环境友好的能源。全球每年的水力发电量达到3930 TW·h,占全球总发电量的16%,同时占可再生能源发电量的78%(2015年)。水电和气候变化具有双重的关系。一方面,水电作为一种重要的可再生能源,对于避免温室气体排放和减缓全球变暖贡献显著;另一方面,气候变化会改变河道流量,进而影响水资源可用量和水力发电。水电对于减少温室气体排放和保障能源供应至关重要。与常规燃煤电厂相比,水电每年可避免3×109 t CO_2的排放,占全球年CO_2排放量的9%。除了对电力行业的贡献,水电项目还可作为多功能水库的融资工具,以及水资源应对气候变化影响的一项适应性措施,这是因为水库的蓄水可作为气候变化的缓冲器,有大水库调节的流域更能适应水资源变化,而不容易受到气候变化的影响。从全球层面来看,预期气候变化对现有全球水力发电的整体影响较小,甚至可能产生一些积极影响。然而,世界不同地区甚至各个国家内部可能存在巨大差异。总之,对水电的解读为:水电是一种廉价、成熟的技术,对减缓气候变化有重大贡献,且可以在水资源适应气候变化中发挥重要作用。有必要关注并减轻巨大的环境压力和社会成本,预计未来几十年内可新增水电装机容量1000 GW。Ignacio Escuder-Bueno Guido Mazza Adrian Morales-Torres Jesica T.

11Endoscopic ultrasound diagnostic gain over computed tomography and magnetic resonance cholang-iopancreatography in defining etiology of idiopathic acute pancreatitis显示文摘BACKGROUND About 10%-30%of acute pancreatitis remain idiopathic(IAP)even after clinical and imaging tests,including abdominal ultrasound(US),contrast-enhanced computed tomography(CECT)and magnetic resonance cholangiopancreatography(MRCP).This is a relevant issue,as up to 20%of patients with IAP have recurrent episodes and 26%of them develop chronic pancreatitis.Few data are available on the role of EUS in clarifying the etiology of IAP after failure of one or more cross-sectional techniques.AIM To evaluate the diagnostic gain after failure of one or more previous crosssectional exams.METHODS We retrospectively collected data about consecutive patients with AP and at least one negative test between US,CECT and MRCP,who underwent linear EUS between January 2017 and December 2020.We investigated the EUS diagnostic yield and the EUS diagnostic gain over different combinations of these crosssectional imaging techniques for the etiologic diagnosis of AP.Types and frequency of EUS diagnosis were also analyzed,and EUS diagnosis was compared with the clinical parameters.After EUS,patients were followed-up for a median of 31.5 mo to detect cases of pancreatitis recurrence.RESULTS We enrolled 81 patients(63%males,mean age 61±18,23%with previous cholecystectomy,17%with recurrent pancreatitis).Overall EUS diagnostic yield for AP etiological diagnosis was 79%(20%lithiasis,31%acute on chronic pancreatitis,14%pancreatic solid or cystic lesions,5%pancreas divisum,5%autoimmune pancreatitis,5%ductal abnormalities),while 21%remained idiopathic.US,CECT and MRCP,taken alone or in combination,led to AP etiological diagnosis in 16(20%)patients;among the remaining 65 patients,49(75%)obtained a diagnosis at EUS,with an overall EUS diagnostic gain of 61%.Sixty-eight patients had negative US;among them,EUS allowed etiological diagnosis in 59(87%).Sixty-three patients had a negative CECT;among them,47(74%)obtained diagnosis with EUS.Twenty-four had a negative MRCP;among them,20(83%)had EUS diagnosis.Twenty-one had negative CT+MRCP,of which 17(81%)had EUS diagnosis,with a EUS diagnostic gain of 63%.Patients with biliary etiology and without previous cholecystectomy had higher median values of alanine aminotransferase(154 vs 25,P=0.010),aspartate aminotransferase(95 vs 29,P=0.018),direct bilirubin(1.2 vs 0.6,P=0.015),gammaglutamyl transpeptidase(180 vs 48,P=0.006)and alkaline phosphatase(150 vs 72,P=0.015)Chronic pancreatitis diagnosis was more frequent in patients with recurrent pancreatitis at baseline(82%vs 21%,P<0.001).During the follow-up,AP recurred in 3 patients,one of which remained idiopathic.CONCLUSION EUS is a good test to define AP etiology.It showed a 63%diagnostic gain over CECT+MRCP.In suitable patients,EUS should always be performed in cases of IAP.Further prospective studies are needed.Stefano Mazza Biagio Elvo Clara Benedetta Conti Andrea Drago Maria Chiara Verga Sara Soro Annalisa De Silvestri Fabrizio Cereatti Roberto Grassia 2022World Journal of Gastrointestinal Endoscopy2022,14,6:3
12富含anthocyanin的水果提取物对血管内皮细胞产生PGE_2的影响研究显示文摘目的研究富含anthocyanin的水果提取物对血管内皮细胞产生PGE2的影响.方法将人类正常的血管内皮细胞CRL-2606在Kaighn's F12K培养基中(补加有10%FBS,0.1mg/ml肝素,0.03mg/ml的ECGS,50μg/ml链霉素和500U/ml青霉素)37℃、5%CO2的条件下培养至接近融合,然后在含有从水果中提取出的anthocyanin的F12K培养基中添加或不添加100ng/mlLPS,继续培养18小时,测定细胞生存率,并将培养液离心,收集上清液,用STAT-Prostaglandin E2 EIA Kit试剂盒测定培养基上清液中的PGE2浓度.结果当CRL-2606细胞暴露于300μg/ml或以上的Chokeberry提取物中时,细胞的生存率低于60%,且表现出一定的剂量效应关系.而50~400μg/ml的蓝莓提取物和100~700μg/ml的黑醋栗提取物未显示细胞毒性.LPS刺激可使细胞PEG2释放量增加一倍以上,蓝莓提取物可明显抑制由于LPS刺激引起的PGE2释放增加,100μg/ml的蓝莓提取物可完全抑制此作用而使其含量维持于正常水平.700μg/ml的黑醋栗提取物对处于LPS刺激下的CRL-2606细胞具有一定的抑制PGE2释放作用.而对于处于LPS刺激下的细胞,500μg/ml以上的Chokeberry提取物能抑制PGE2的释放.结论富含anthocyanin的黑醋栗、蓝莓以及Chokeberry提取物可以抑制由LPS刺激引起的血管内皮细胞释放PEG2增加的作用,具有一定的抗炎、抗氧化作用.韩光亮 李翠梅 Mazza G 杨晓光 2005卫生研究2005,34,5:3
13Arthroscopic vs open ankle arthrodesis:A prospective case series with seven years follow-up显示文摘BACKGROUND The osteoarthritis of the ankle,although less common than other joints,is associated with severe functional limitation.Surgical options are ankle arthroscopic debridement,osteotomies,ankle arthrodesis and ankle arthroplasty.Ankle arthroplasty is increasingly used thanks to the new implants design,but ankle arthrodesis still represents the most used technique and it can be performed arthroscopically or with an open procedure.AIM To compare mid-term results of arthroscopic vs open ankle arthrodesis of patients affected by end-stage ankle arthritis.METHODS This study enrolled 23 patients,which underwent ankle arthrodesis.The patients were divided into 2 groups:group A(open procedure;n=11)and group B(arthroscopic procedure,n=12),the two groups were homogeneous with regard to age and body mass index(P=0.347).The American Orthopaedic Foot and Ankle score(AOFAS),Freiburg Ankle score(FAS)and visual analogue scale for pain intensity were evaluated preoperatively,at six months and at final follow-up of 7.6 years in group A and 7.3 years in group B(P=0.364).RESULTS Patients in the arthroscopic group showed better results at six-month follow-up compared to the open group at the AOFAS(group A,62.2;group B,78.5;P<0.05)and the FAS(group A,61.1;group B,70.3;P=0.015)scores.Pain relief was achieved in both groups at six-month follow-up(group A,1.4;group B,0.9;P=0.162).Both open and arthroscopic groups showed improved clinical outcomes from baseline to final follow-up(P>0.05).Hospital stay was shorter in group B than in group A(P=0.001).More complications were reported in the open group than in the arthroscopic group(P=0.459).CONCLUSION The arthroscopic and the open arthrodesis are valid and safe options for the treatment of ankle arthritis on the basis of clinical outcomes at 7 years follow-up.Moreover,the arthroscopic treatment shows faster improvement at six-month follow-up in comparison with the open group.Federico Morelli Giorgio Princi Matteo Romano Cantagalli Marco Rossini Ludovico Caperna Daniele Mazza Andrea Ferretti 2021World Journal of Orthopedics2021,12,12:3
14Chest pain caused by multiple exostoses of the ribs: A case report and a review of literature显示文摘The aim of this paper is to report an exceptional case of multiple internal exostoses of the ribs in a young patient affected by multiple hereditary exostoses(MHE) coming to our observation for chest pain as the only symptom of an intra-thoracic localization. A 16 years old patient with familiar history of MHE came to our observation complaining a left-sided chest pain. This pain had increased in the last months with no correlation to a traumatic event. The computed tomography(CT) scan revealed the presence of three exostoses located on the left third, fourth and sixth ribs, all protruding into the thoracic cavity, directly in contact with visceral pleura. Moreover, the apex of the one located on the sixth rib revealed to be only 12 mm away from pericardium. Patient underwent video-assisted thoracoscopy with an additional 4-cm mini toracotomy approach. At the last 1-year followup, patient was very satisfied and no signs of recurrence or major complication had occured. In conclusion, chest pain could be the only symptom of an intra-thoracic exostoses localization, possibly leading to serious complications. Thoracic localization in MHE must be suspected when patients complain chest pain. A chest CT scan is indicated to confirm exostoses and to clarify relationship with surrounding structures. Video-assisted thoracoscopic surgery can be considered a valuable option for exostoses removal, alone or in addiction to a mini-thoracotomy approach, in order to reduce thoracotomy morbidity.Daniele Mazza Mattia Fabbri Cosma Calderaro Carlo Iorio Luca Labianca Camilla Poggi Francesco Turturro Antonello Montanaro Andrea Ferretti 2017World Journal of Orthopedics2017,8,5:2
