| 1 | 2018加拿大心境障碍与焦虑障碍治疗协作组/国际双相障碍学会指南:双相障碍的管理显示文摘加拿大心境障碍与焦虑障碍治疗协作组(Canadian Network for Mood and Anxiety Treatments,CANMAT)曾于2005年发布了第1版双相障碍管理指南,并分别于2007、2009和2013年对该指南进行了更新,其中最近的2次更新是与国际双相障碍学会(International Society for Bipolar Disorders,ISBD)合作完成。2018版CANMAT/ISBD双相障碍治疗指南(以下简称指南)反映了自2005年首版指南发表以来本领域取得的重大进展,包括疾病诊断与疾病管理的更新以及药物治疗与心理治疗的近期研究进展。这些前沿进展中综合考虑了循证证据的级别,并基于治疗疗效、临床实践经验、安全性、耐受性和药物导致的转相风险等,对一线、二线及三线治疗方案进行了简明而清晰的推荐。本指南中新增内容涵盖了双相Ⅰ型障碍(BD-Ⅰ)的躁狂发作急性期、抑郁发作急性期和双相障碍维持期的一线及二线治疗推荐等级划分。这种对治疗推荐等级的划分综合考虑了治疗方法对双相障碍不同时相的影响,将进一步帮助临床医生做出基于循证证据的治疗决策。锂盐、喹硫平、双丙戊酸盐、阿塞那平、阿立哌唑、帕利哌酮、利培酮和卡利拉嗪单药或联合使用被推荐为躁狂发作急性期的一线治疗选择。BD-Ⅰ抑郁期的一线治疗选择包括喹硫平、鲁拉西酮、锂盐、拉莫三嗪单药,鲁拉西酮联合锂盐或双丙戊酸盐或拉莫三嗪辅助治疗。尽管急性期治疗有效的药物通常应继续用于BD-Ⅰ的维持期治疗,但也存在一些特殊情况(例如抗抑郁药)。现有数据表明,锂盐、喹硫平、双丙戊酸盐、拉莫三嗪、阿塞那平和阿立哌唑单药或联合治疗应被视为维持治疗的初始或更换治疗方案时的一线选择。除了探讨BD-Ⅰ的相关问题外,本指南中还对双相Ⅱ型障碍(BD-Ⅱ)的临床管理进行了系统回顾并给予治疗推荐,同时针对特殊人群也有相关推荐,如处于各个生殖周期的女性、儿童、青少年和老年人。此外,本指南中还讨论了特定精神疾病及共病(如物质滥用、焦虑障碍和代谢性疾病)的影响。最后,本指南中概述了安全性和药物监测的相关问题。CANMAT/ISBD工作组希望本指南能够成为全球临床医生的实用工具。 | Lakshmi N Yatham Sidney H Kennedy Sagar V Parikh Ayal Sehaffer David J Bond Benicio N Frey Verinder Sharma Benjamin I Goldstein Soham Rej Serge Beaulieu Martin Alda Glenda MaeQueen Roumen V Milev Arun Ravindran Claire O'Donovan Diane Mclntosh Raymond W Lam Gustavo Vazquez Flavio Kapczinski Roger S Melntyre Jan Kozicky Shigenobu Kanba Beny Lafer Trisha Suppes Joseph R Calabrese Eduard Vieta Gin Malhi Robert M Post Michael Berk 胡晨(译) 王刚(译) | 2019 | 中华精神科杂志2019，52，1： | 25 |
| 2 | Current status of laparoscopic and robotic ventral mesh rectopexy for external and internal rectal prolapse显示文摘External and internal rectal prolapse with their affiliated rectocele and enterocele, are associated with debilitating symptoms such as obstructed defecation, pelvic pain and faecal incontinence. Since perineal procedures are associated with a higher recurrence rate, an abdominal approach is commonly preferred. Despite the description of greater than three hundred different procedures, thus far no clear superiority of one surgical technique has been demonstrated. Ventral mesh rectopexy(VMR) is a relatively new and promising technique to correct rectal prolapse. In contrast to the abdominal procedures of past decades, VMR avoids posterolateral rectal mobilisation and thereby minimizes the risk of postoperative constipation. Because of a perceived acceptable recurrence rate, good functional results and low mesh-related morbidity in the short to medium term, VMR has been popularized in the past decade. Laparoscopic or robotic-assisted VMR is now being progressively performed internationally and several articles and guidelines propose the procedure as the treatment of choice for rectal prolapse. In this article, an outline of the current status of laparoscopic and robotic ventral mesh rectopexy for the treatment of internal and external rectal prolapse is presented. | Jan J van Iersel Tim JC Paulides Paul M Verheijen John W Lumley Ivo AMJ Broeders Esther CJ Consten | 2016 | World Journal of Gastroenterology2016，22，21： | 20 |
| 3 | Management of recurrent rectal cancer:A population based study in greater Amsterdam显示文摘AIM: To analyze,retrospectively in a population-based study,the management and survival of patients with recurrent rectal cancer initially treated with a macroscopically radical resection obtained with total mesorectal excision (TME). METHODS: All rectal carcinomas diagnosed during 1998 to 2000 and initially treated with a macroscopically radical resection (632 patients) were selected from the Amsterdam Cancer Registry. For patients with recurrent disease,information on treatment of the recurrence was collected from the medical records. RESULTS: Local recurrence with or without clinically apparent distant dissemination occurred in 62 patients (10%). Thirty-two patients had an isolated local recurrence. Ten of these 32 patients (31%) underwent radical re-resection and experienced the highest survival (three quarters survived for at least 3 years). Eight patients (25%) underwent non-radical surgery (median survival 24 mo),seven patients (22%) were treated with radio-and/or chemotherapy without surgery (median survival 15 mo) and seven patients (22%) only received best supportive care (median survival 5 mo). Distant dissemination occurred in 124 patients (20%) of whom 30 patients also had a local recurrence. The majority (54%) of these patients were treated with radio-and/or chemotherapy without surgery (median survival 15 mo). Twenty-seven percent of these patients only received best supportive care (median survival 6 mo),while 16% underwent surgery for their recurrence. Survival was best in the latter group (median survival 32 mo). CONCLUSION: Although treatment options and survival are limited in case of recurrent rectal cancer after radical local resection obtained with TME,patients can benefit from additional treatment,especially if a radical resection is feasible. | Roel Bakx Otto Visser Judith Josso Sybren Meijer J Frederik M Slors J Jan B van Lanschot | 2008 | World Journal of Gastroenterology2008，14，39： | 17 |
| 4 | Clinically detected gastroenteropancreatic neuroendocrine tumors are on the rise: Epidemiological changes in Germany显示文摘AIM:To study the epidemiologic changes of gastroenteropancreatic neuroendocrine tumors(GEP-NET)in Germany,we analyzed two time periods 1976-1988 and1998-2006.METHODS:We evaluated epidemiological data of GEP-NET from the former East German National Cancer Registry(DDR Krebsregister,1976-1988)and its successor,the Joint Cancer Registry(GKR,1998-2006),which was founded after German reunification.Due to a particularly substantial database the epidemiological data from the federal states of Mecklenburg-Western Pomerania,Saxony,Brandenburg and Thuringia,covering a population of more than 10.8 million people,were analyzed.Survival probabilities were calculated using life table analysis.In addition,GEP-NET patients were evaluated for one or more second(non-GEP-NET)primary malignancies.RESULTS:A total of 2821 GEP neuroendocrine neoplasms were identified in the two registries.The overall incidence increased significantly between 1976 and2006 from 0.31(per 100.000 inhabitants per year)to2.27 for men and from 0.57 to 2.38 for women.In the later period studied(2004-2006),the small intestine was the most common site.Neuroendocrine(NE)neoplasms of the small intestine showed the largest absolute increase in incidence,while rectal NE neoplasms exhibited the greatest relative increase.Only the incidence of appendiceal NET in women showed little change between 1976 and 2006.Overall survival of patients varied for sex,tumor site and the two periods studied but improved significantly over time.Interestingly,about 20%of the GEP-NET patients developed one or more second malignancies.Their most common location was the gastrointestinal tract.GEP-NET patients without second malignancies fared better than those with one or more of them.CONCLUSION:The number of detected GEP-NET increased about 5-fold in Germany between 1976 and2006.At the same time,their anatomic distribution changed,and the survival of GEP-NET patients improved significantly.Second malignancies are common and influence the overall survival of GEP-NET patients.Thus,GEP-NET warrant our attention as well as intensive research on their tumorigenesis. | Hans Scherübl Brigitte Streller Roland Stabenow Hermann Herbst Michael Hopfner Christoph Schwertner Joachim Steinberg Jan Eick Wanda Ring Krishna Tiwari Soren M Zappe | 2013 | World Journal of Gastroenterology2013，19，47： | 16 |

| 6 | Underexpression of LATS1 TSG in colorectal cancer is associated with promoter hypermethylation显示文摘AIM:To investigate large tumor suppressor 1 (LATS1 ) expression, promoter hypermethylation, and microsatellite instability in colorectal cancer (CRC).METHODS:RNA was isolated from tumor tissue of 142 CRC patients and 40 colon mucosal biopsies of healthy controls. After reverse transcription, quantitative polymerase chain reaction (PCR) was performed, and LATS1 expression was normalized to expression of the ACTB and RPL32 housekeeping genes. To analyze hypermethylation, genomic DNA was isolated from 44 tumor CRC biopsies, and methylation-specific PCR was performed. Microsatellite instability (MSI) status was checked with PCR using BAT26, BAT25, and BAT40 markers in the genomic DNA of 84 CRC patients, followed by denaturing gel electrophoresis. RESULTS:Decreased LATS1 expression was found in 127/142 (89.4%) CRC cases with the average ratio of the LATS1 level 10.33 ± 32.64 in CRC patients vs 32.85 ± 33.56 in healthy controls. The lowest expression was found in Dukes' B stage tumors and G1 (welldifferentiated) cells. Hypermethylation of the LATS1 promoter was present in 25/44 (57%) CRC cases analyzed. LATS1 promoter hypermethylation was strongly associated with decreased gene expression; methylated cases showed 162× lower expression of LATS1 than unmethylated cases. Although high-grade MSI (mutation in all three markers) was found in 14/84 (17%) cases and low-grade MSI (mutation in 1-2 markers) was found in 30/84 (36%) cases, we found no association with LATS1 expression. CONCLUSION:Decreased expression of LATS1 in CRC was associated with promoter hypermethylation, but not MSI status. Such reduced expression may promote progression of CRC. | Piotr M Wierzbicki Krystian Adrych Dorota Kartanowicz Marcin Stanislawowski Anna Kowalczyk Janusz Godlewski Iwona Skwierz-Bogdanska Krzysztof Celinski Tomasz Gach Jan Kulig Bartlomiej Korybalski Zbigniew Kmiec | 2013 | World Journal of Gastroenterology2013，19，27： | 8 |

| 11 | Collagen/hyaluronan based hydrogels releasing sulfated hyaluronan improve dermal wound healing in diabetic mice via reducing inflammatory macrophage activity显示文摘Sustained inflammation associated with dysregulated macrophage activation prevents tissue formation and healing of chronic wounds.Control of inflammation and immune cell functions thus represents a promising approach in the development of advanced therapeutic strategies.Here we describe immunomodulatory hyaluronan/collagen(HA-AC/coll)-based hydrogels containing high-sulfated hyaluronan(sHA)as immunoregulatory component for the modulation of inflammatory macrophage activities in disturbed wound healing.Solute sHA downregulates inflammatory activities of bone marrow-derived and tissue-resident macrophages in vitro.This further affects macrophage-mediated pro-inflammatory activation of skin cells as shown in skin ex-vivo cultures.In a mouse model of acute skin inflammation,intradermal injection of sHA downregulates the inflammatory processes in the skin.This is associated with the promotion of an anti-inflammatory gene signature in skin macrophages indicating a shift of their activation profile.For in vivo translation,we designed HA-AC/coll hydrogels allowing delivery of sHA into wounds over a period of at least one week.Their immunoregulatory capacity was analyzed in a translational experimental approach in skin wounds of diabetic db/db mice,an established model for disturbed wound healing.The sHA-releasing hydrogels improved defective tissue repair with reduced inflammation,augmented pro-regenerative macrophage activation,increased vascularization,and accelerated new tissue formation and wound closure. | Sophia Hauck Paula Zager Norbert Halfter Elke Wandel Marta Torregrossa Ainur Kakpenova Sandra Rother Michelle Ordieres Susann Räthel Albrecht Berg Stephanie Möller Matthias Schnabelrauch Jan C.Simon Vera Hintze Sandra Franz | 2021 | Bioactive Materials2021，6，12： | 7 |
| 12 | 大气二氧化氮与每日总死亡率、心血管和呼吸系统疾病死亡率的短期关联:398个城市的多中心分析显示文摘目的:采用统一的分析方案,评估全球多个国家/地区的二氧化氮(NO_(2))与总死亡率、心血管和呼吸系统疾病死亡率之间的短期关联。研究设计:采用两阶段的时间序列分析方法、过度离散的广义线性模型和多水平meta分析。研究地点:22个低到高收入国家/地区的398个城市。主要结局指标:1973—2018年逐日总死亡人数(6280万人)、心血管疾病死亡人数(1970万人)和呼吸系统疾病死亡人数(550万人)。结果:平均而言,NO_(2)浓度在滞后1天(前1天)每增加10μg/m^(3),会导致总死亡率、心血管和呼吸系统疾病死亡率分别增加0.46%(95%可信区间0.36%~0.57%)、0.37%(0.22%~0.51%)、0.47%(0.21%~0.72%)。在对共污染物(PM_(10)、PM_(2.5)、臭氧、二氧化硫和一氧化碳)进行调整后,这些关联仍然很稳定。所有3种死因的暴露-反应曲线几乎是线性的,没有明显的阈值。在398个城市中,可归因于高过假定零水平的NO_(2)浓度造成的死亡比例为1.23%(95%可信区间0.96%~1.51%)。结论:这项多中心研究提供了关于NO_(2)短期暴露与总死亡率、心血管和呼吸系统死亡风险之间的独立和线性关联的关键证据,说明通过加强NO_(2)的控制和监管限制标准,可获得人群水平的健康收益。 | 孟夏 刘聪(校) 陈仁杰 郑湃(译) 阚海东(校) Francesco Sera Ana Vicedo-Cabrera Ai Milojevic Maria Guo Yuming Tong Shilu Micheline de Sousa Zanotti Stagliorio Coelh Paulo Hilario Nascimento Saldiva Eric Lavigne Patricia Matus Correa Nicolas Valdes Ortega Samuel Osorio Garcia Jan Kysely Ales Urban Hans Orru Marek Maasikmets Jouni J K Jaakkola Niilo Ryti Veronika Huber Alexandra Schneider Klea Katsouyanni Antonis Analitis Masahiro Hashizume Yasushi Honda Chris Fook Sheng Ng Baltazar Nunes João Paulo Teixeira Iulian Horia Holobaca Simona Fratianni Ho Kim Aurelio Tobias Carmeníniguez Bertil Forsberg ChristoferÅström Martina S Ragettli Yue-Liang Leon Guo Shih-Chun Pan Shanshan Li Michelle L Bell Antonella Zanobetti Joel Schwartz Tangchun Wu Antonio Gasparrini | 2021 | 英国医学杂志中文版2021，24，8： | 7 |
| 13 | 秸秆还田方式对不同土壤条件下玉米苗期生长发育的影响显示文摘为探究不同秸秆还田方式对玉米苗期生长影响的生态生理机制,本试验选择3种土壤类型(黑土、黄土、酸土),设置2个还田方式(秸秆覆盖还田、秸秆混拌还田),以及黑土条件下2种石子处理方式(石子覆盖处理、石子混拌处理),比较处理间苗期地上部、地下部形态以及抗逆性生理指标的变化。结果表明:秸秆还田显著增加了玉米苗期株高、叶面积、干物质重、叶绿素荧光参数、根系长度、根系表面积、根尖数以及根系活跃吸收面积,其中秸秆混拌处理优于秸秆覆盖处理;秸秆还田降低了超氧化物歧化酶、过氧化氢酶活性和丙二醛含量,其中覆盖处理好于混拌处理;尽管黄土与黑土、酸土间肥力具有差异,但秸秆还田效果相同;两种石子处理均抑制根系的生长,在覆盖处理或混拌处理方式下秸秆还田处理均显著好于石子处理,因此,秸秆还田主要通过改变土壤生物化学性质促进根系生长和养分吸收,进而促进地上部的生长。 | 王帅 朱涵宇 杨占惠 姜籽竹 陶雨朝 刘昌壮 Jan M FAHEEM 李明 | 2022 | 生态学杂志2022，41，3： | 7 |
| 14 | Hot deformation of Mg-Y-Zn alloy with a low content of the LPSO phase studied by in-situ synchrotron radiation diffraction显示文摘The compressive deformation behavior of the extruded WZ42(Mg98.5Y1Zn0.5 in at.%)magnesium alloy containing a low amount of long-period stacking ordered(LPSO)phase was studied by in-situ synchrotron radiation diffraction technique.Tests were conducted at temperatures between room temperature and 350℃.Detailed microstructure investigation was provided by scanning electron microscopy,particularly the backscattered electron imaging and electron backscatter diffraction technique.The results show that twinning lost its dominance and kinking of the LPSO phase became more pronounced with increasing deformation temperature.No cracks of the LPSO phase and no debonding r at the interface between the LPSO phase and the Mg matrix were observed at temperatures above 200℃.At 350℃,the LPSO phase lost its strengthening effect and the deformation of the alloy was mainly realized by the dynamic recrystallization of the Mg matrix. | Klaudia Horváth Fekete Daria Drozdenko Jan Capek Kristián Máthis Domonkos Tolnai Andreas Stark Gerardo Garcés Patrik Dobron | 2020 | Journal of Magnesium and Alloys2020，8，1： | 5 |

| 16 | 柴北缘锡铁山榴辉岩退变质成因角闪石^40Ar/^39Ar年代学研究显示文摘采用激光阶段加热^40Ar/^39Ar技术,对柴达木盆地北缘锡铁山榴辉岩退变质作用形成的榴闪岩和斜长角闪岩之角闪石进行了定年分析。09NQ44Amp来自榴闪岩,各阶段表观年龄(以现代空气氩^40Ar/^36Ar比值295.5扣除非放射性成因^40Ar)构成了单调下降的阶梯状年龄谱。在反等时线图解上,2~4阶段数据点和5~18阶段数据点分别构成了两条等时线,等时年龄分别为427.6±10Ma和425.1±2.6Ma,对应的初始40Ar/36Ar比值则分别为435.2±6.1和705.3±13。角闪石09NQ43Amp来自榴辉岩强烈退变质作用形成的斜长角闪岩,40Ar/39Ar阶段加热分析也获得单调下降的年龄谱,在反等时线图解上其数据点3~6阶段和7~16阶段分别构成了两条等时线,等时年龄分别为418.9±2.9Ma和418.1±2.1Ma,对应的初始40Ar/36Ar比值则分别为493.7±2.8和685.8±34.3。等时线截距值高于现代大气40Ar/36Ar比值,表明角闪石中含过剩40Ar。同时,由低温和中-高温阶段加热数据点分别构成两条等时年龄基本一致,截距值却明显不同的等时线,表明在角闪石热力学性质不同的源区,存在两期明显不同且未混合的初始捕获Ar组分。等时年龄425~418Ma代表的是锡铁山榴辉岩角闪岩相退变质作用发生的时间。等时线图解法虽然有效的校正了角闪石中的过剩40Ar,但仅根据表观年龄图谱和等时线图谱还无法清晰判断过剩40Ar在角闪石中的赋存状态,有待进一步探讨。 | 胡荣国 王敏 Jan R WIJBRANS Fraukje M BROUWER 邱华宁 | 2013 | 岩石学报2013，29，9： | 5 |
| 17 | T-regulatory lymphocytes in peripheral blood of gastric and colorectal cancer patients显示文摘AIM: To assess the absolute number of T-regulatory cells (Tregs; CD4+CD25+Foxp3+) in the peripheral blood of gastric and colorectal cancer patients. METHODS: We enrolled 70 cancer patients (33 gastric cancer, 37 colorectal cancer) and 17 healthy volunteers. The CD3+CD4+ lymphocytes and CD4+CD25+Foxp3+ Tregs in the peripheral blood were analyzed with flow cytometry. The absolute numbers of Tregs were calculated based on the CD4+CD25+Foxp3+ cells percent-age of CD3+CD4+ cells and the absolute numbers of CD3+CD4+ cells per microliter. RESULTS: The mean number of CD4+CD25+Foxp3+ cells per microliter in colorectal cancer patients was 15.7 (SD: 21.8), for gastric cancer patients 12.2 (SD: 14.3), and for controls 17.5 (SD: 11.4). The absolute number of Tregs was significantly lower in gastric cancer patients than in controls (P = 0.026). There was no statistically significant difference for gastric vs colorectal cancer or colorectal cancer vs controls. The absolute number of Tregs was also significantly depressed in N+ vs Ncancer patients [22.0 (27.7) vs 10.1 (9.0), P = 0.013], and in the subgroup of gastric cancer patients [30.3 (27.6) vs 9.6 (8.0), P = 0.003]. No statistical difference was observed in the proportion of Tregs in the CD4+ population between the groups. CONCLUSION: The absolute number of Tregs in peripheral blood of gastric cancer but not colorectal cancer patients was significantly decreased in comparison with that in healthy controls. | Antoni M Szczepanik Maciej Siedlar Marek Sierzega Dominika Goroszeniuk Karolina Bukowska-Strakova Antoni Czupryna Jan Kulig | 2011 | World Journal of Gastroenterology2011，17，3： | 5 |
| 18 | Lrp1 in osteoblasts controls osteoclast activity and protects against osteoporosis by limiting PDGF–RANKL signaling显示文摘Skeletal health relies on architectural integrity and sufficient bone mass, which are maintained through a tightly regulated equilibrium of bone resorption by osteoclasts and bone formation by osteoblasts. Genetic studies have linked the gene coding for low-density lipoprotein receptor-related protein1(Lrp1) to bone traits but whether these associations are based on a causal molecular relationship is unknown. Here, we show that Lrp1 in osteoblasts is a novel regulator of osteoclast activity and bone mass.Mice lacking Lrp1 specifically in the osteoblast lineage displayed normal osteoblast function but severe osteoporosis due to highly increased osteoclast numbers and bone resorption. Osteoblast Lrp1 limited receptor activator of NF-κB ligand(RANKL) expression in vivo and in vitro through attenuation of platelet-derived growth factor(PDGF-BB) signaling. In co-culture, Lrp1-deficient osteoblasts stimulated osteoclastogenesis in a PDGFRβ-dependent manner and in vivo treatment with the PDGFR tyrosine kinase inhibitor imatinib mesylate limited RANKL production and led to complete remission of the osteoporotic phenotype. These results identify osteoblast Lrp1 as a key regulator of osteoblast-to-osteoclast communication and bone mass through a PDGF–RANKL signaling axis in osteoblasts and open perspectives to further explore the potential of PDGF signaling inhibitors in counteracting bone loss as well as to evaluate the importance of functional LRP1 gene variants in the control of bone mass in humans. | Alexander Bartelt Friederike Behler-Janbeck F.Timo Beil Till Koehne Brigitte Müller Tobias Schmidt Markus Heine Laura Ochs Tayfun Yilmaz Martin Dietrich Jan P.Tuckermann Michael Amling Joachim Herz Thorsten Schinke Joerg Heeren Andreas Niemeier | 2018 | Bone Research2018，6，1： | 5 |
| 19 | RANK-ligand and osteoprotegerin as biomarkers in the differentiation between periprosthetic joint infection and aseptic prosthesis loosening显示文摘AIM To assess serum levels of RANK-ligand(RANKL) and osteoprotegerin(OPG) as biomarkers for periprosthetic joint infection(PJI) and compare their accuracy with standard tests.METHODS One hundred and twenty patients presenting with a painful total knee or hip arthroplasty with indication for surgical revision were included in this prospective clinical trial. Based on standard diagnostics(joint aspirate, microbiological, and histological samples) and Musculoskeletal Infection Society consensus classification,patients were categorized into PJI, aseptic loosening,and control groups. Implant loosening was assessed radiographically and intraoperatively. Preoperative serum samples were collected and analyzed for RANKL, OPG, calcium, phosphate, alkaline phosphatase(AP), and the bone-specific subform of AP(b AP). Statistical analysis was carried out, testing for significant differences between the three groups and between stable and loose implants. RESULTS All three groups were identical in regards to age, gender, and joint distribution. No statistically significant differences in the serum concentration of RANKL(P = 0.16) and OPG(P = 0.45) were found between aseptic loosening and PJI, with a trend towards lower RANKL concentrations and higher OPG concentrations in the PJI group. The RANKL/OPG ratio was significant for the comparison between PJI and non-PJI(P = 0.005). A ratio > 60 ruled out PJI in all cases(specificity: 100%, 95%CI: 89, 11% to 100.0%) but only 30% of non-PJI patients crossed this threshold. The positive predictive value remained poor at any cut-off. In the differentiation between stable and loose implants, none of the parameters measured(calcium, phosphate, AP, and b AP) showed a significant difference, and only AP and b AP measurements showed a tendency towards higher values in the loosened group(with P = 0.09 for AP and P = 0.19 for b AP). CONCLUSION Lower RANKL and higher OPG concentrations could be detected in PJI, without statistical significance. | Max J Friedrich Matthias D Wimmer Jan Schmolders Andreas C Strauss Milena M Ploeger Hendrik Kohlhof Dieter C Wirtz Sascha Gravius Thomas M Randau | 2017 | World Journal of Orthopedics2017，8，4： | 4 |

Ultrasound was performed with and without the addition of unspecific contrast agents. MAd CAM-1-targeted contrast agent was used to detect and quantify MAd CAM-1 expression. Inflammatory driven colorectal azoxymethane(AOM)/DSS-induced carcinogenesis was examined on day 42 and 84 using VEGF-targeted contrast agent. Highly specific tissue echogenicity was quantified using specialized software. Sonographic findings were correlated to tissue staining, western blot analysis and immunohistochemistry to quantify the degree of inflammation and stage of carcinogenesis. RESULTS Native ultrasound detected increased general bowel wall thickening that correlated with more progressed and more severe DSS-colitis(healthy mice: 0.3 mm ± 0.03 vs six days DSS: 0.5 mm ± 0.2 vs nine days DSS: 0.6 mm ± 0.2, P < 0.05). Moreover, these sonographic findings correlated well with clinical parameters such as weight loss(r2 = 0.74) and histological damage(r2 = 0.86)(P < 0.01). In acute DSS-induced murine colitis, CEUS targeted against MAd CAM-1 detected and differentiated stages of mild, moderate and severe colitis via calculation of mean pixel contrast intensity in decibel(9.6 d B ± 1.6 vs 12.9 d B ± 1.4 vs 18 d B ± 3.33, P < 0.05). Employing the AOM/DSSinduced carcinogenesis model, tumor development was monitored by CEUS targeted against VEGF and detected a significantly increased echogenicity in tumors as compared to adjacent healthy mucosa(healthy mucosa, 1.6 d B ± 1.4 vs 42 d, 18.2 d B ± 3.3 vs 84 d, 18.6 d B ± 4.9, P < 0.01). Tissue echogenicity strongly correlated with histological analysis and immunohistochemistry findings(VEGF-positive cells in 10 high power fields of healthy mucosa: 1 ± 1.2 vs 42 d after DSS start: 2.4 ± 1.6 vs 84 d after DSS start: 3.5 ± 1.3, P < 0.01). CONCLUSION Molecularly targeted CEUS is a highly specific and noninvasive imaging modality, which characterizes murine intestinal inflammation and carcinogenesis in vivo. | Markus Brückner Jan Heidemann Tobias M Nowacki Friederike Cordes Jorg Stypmann Philipp Lenz Faekah Gohar Andreas Lügering Dominik Bettenworth | 2017 | World Journal of Gastroenterology2017，23，16： | 4 |
