| 1 | Coarctation of the aorta:Management from infancy to adulthood显示文摘Coarctation of the aorta is a relatively common form of congenital heart disease, with an estimated incidence of approximately 3 cases per 10000 births. Coarctation is a heterogeneous lesion which may present across all age ranges, with varying clinical symptoms, in isolation, or in association with other cardiac defects. The first surgical repair of aortic coarctation was described in 1944, and since that time, several other surgical techniques have been developed and modified. Additionally, transcatheter balloon angioplasty and endovascular stent placement offer less invasive approaches for the treatment of coarctation of the aorta for some patients. While overall morbidity and mortality rates are low for patients undergoing intervention for coarctation, both surgical and transcatheter interventions are not free from adverse outcomes. Therefore, patients must be followed closely over their lifetime for complications such as recoarctation, aortic aneurysm, persistent hypertension, and changes in any associated cardiac defects. Considerable effort has been expended investigating the utility and outcomes of various treatment approaches for aortic coarctation, which are heavily influenced by a patient's anatomy, size, age, and clinical course. Here we review indications for intervention, describe and compare surgical and transcatheter techniques for management of coarctation, and explore the associated outcomes in both children and adults. | Rachel D Torok Michael J Campbell Gregory A Fleming Kevin D Hill | 2015 | World Journal of Cardiology2015，7，11： | 27 |

| 3 | 【特刊综述】利用雄激素受体敲除(ARKO)小鼠模型认识人类雄激素缺乏显示文摘雄激素的作用机理很复杂。最近,使用转基因修饰小鼠模型进行的雄激素受体研究使我们对雄激素作用机理有了更进一步的理解。Cre-loxP系统能够完成组织和/或细胞特异性的敲除。通过使用Cre—loxP系统已经获得了大量整体性或组织特异性雄激素受体(ARK0)敲除模型。这些ARKO模型的多个雄激素作用位点,包括心血管系统、免疫和造血系统、骨骼、肌肉、脂肪组织、前列腺和脑,均已被检测。本篇综述着重阐述了通过针对这些雄激素作用位点的ARKO小鼠模型而取得的人类雄激素缺乏的研究成果,并且指出充分理解Cre-loxPdx鼠模型的优缺点才能正确认识其表型。 | Kesha Rana Rachel A Davey Jeffrey D Zajac | 2014 | Asian Journal of Andrology2014，16，2： | 13 |
| 4 | Metastatic pattern in esophageal and gastric cancer:Influenced by site and histology显示文摘BACKGROUND Detailed information on metastatic patterns in of patients with esophageal and gastric cancer is limited.Early recognition of metastases is important to avoid futile locoregional treatments.Furthermore,knowledge on metastatic patterns is necessary for further development of personalized treatment modalities.AIM To gain insight into the metastatic pattern of gastroesophageal cancer.METHODS A nationwide retrospective autopsy study of 3876 patients with adenocarcinoma(AC)or squamous cell carcinoma(SCC)of the esophagus or stomach between 1990 and 2017 was performed.Only patient with metastases were included for analysis.The metastatic pattern was analyzed according to the primary tumor location and histological subtype.RESULTS Metastatic disease was found in 268 esophageal and 331 gastric cancer patients.In esophageal cancer,the most common metastatic locations were liver(56%),distant lymph nodes(53%)and lung(50%).Esophageal AC showed more frequently metastases to the peritoneum and bone compared with esophageal SCC.In gastric cancer,the most common metastatic locations were distant lymph nodes(56%),liver(53%)and peritoneum(51%).Intestinal-type AC of the stomach showed metastases to the liver more frequently,whereas metastases to the bone,female reproductive organs and colorectum were observed more frequently in diffuse-type gastric AC.CONCLUSION This study showed differences in metastatic patterns of patients with esophageal and gastric cancer according to the primary tumor location and histological subtype. | Moniek HP Verstegen Mitchell Harker Carlijn van de Water Jolanda van Dieren Niek Hugen Iris D Nagtegaal Camiel Rosman Rachel S van der Post | 2020 | World Journal of Gastroenterology2020，26，39： | 9 |
| 5 | Role of nitric oxide in the impairment of circular muscle contractility of distended, uninflamed mid-colon in TNBS-induced acute distal colitis in rats显示文摘AIM: To evaluate the role of nitric oxide (NO) in the motor disorders of the dilated uninflamed mid-colon (DUMC)from trinitrobenzene sulfonic acid (TNBS)-induced acute distal colitis in rats.METHODS: Colitis was induced in male Sprague-Dawley rats by a single intracolonic administration of TNBS.Control rats received an enema of 0.9% saline. The rats were killed 48 h after TNBS or saline administration.Macroscopic and histologic lesions of the colon were evaluated. Myeloperoxidase (MPO) and nitric oxide synthase (NOS) activity were measured on the colonic tissue. In TNBS rats, we evaluated spontaneous and evoked contractile activity in circular muscle strips derived from DUMC in comparison to the same colonic segment of control rats, both in the presence and in the absence of a non-selective NOS isoforms inhibitor N-nitro-Larginine (L-NNA). Pharmacological characterization of electric field stimulation (EFS)-evoked contractile responses was also performed.RESULTS: In TNBS rats, the distal colon showed severe histological lesions and a high MPO activity, while the DUMC exhibited normal histology and MPO activity.Constitutive NOS activity was similar in TNBS and control rats, whereas inducible NOS activity was significantly increased only in the injured distal colon of TNBS rats.Isometrically recorded mechanical activity of circular muscle strips from DUMC of TNBS rats showed a marked reduction of the force and frequency of spontaneous contractions compared to controls, as well as of the contractile responses to a contracting stimulus. In the presence of L-NNA, the contractile activity and responses displayed a significantly greater enhancement compared to controls. The pharmacological characterization of EFS contractile responses showed that a cooperative-like interaction between cholinergic muscarinic and tachykinergic neurokinin 1 and 2 receptors mediated transmission in DUMC of TNBS rats vs a simple additive interaction in controls.CONCLUSION: The results of this study show that, during TNBS-induced acute distal colitis, circular muscle intrinsic contractile mechanisms and possible enteric neural excitatory activity are inhibited in the distended uninflamed mid-colon. Suppression of NO synthesis markedly improves spontaneous and evokes muscle contractions, in spite of any evident change in local NO activity. | Luciano Onori Annalisa Aggio Simona D'Alo' Paola Muzi Maria Grazia Cifone Gabriella Mellillo Rachele Ciccocioppo Gennaro Taddei Giuseppe Frieri Giovanni Latella | 2005 | World Journal of Gastroenterology2005，11，36： | 7 |
| 6 | Platelet-rich plasma for muscle injuries: A systematic review of the basic science literature显示文摘BACKGROUND Platelet-rich plasma(PRP) is an increasingly used biologic adjunct for muscle injuries, as it is thought to expedite healing. Despite its widespread use, little is known regarding the mechanisms by which PRP produces its efficacious effects in some patients.AIM To clarify the effects of PRP on muscular pathologies at the cellular and tissue levels by evaluating the basic science literature.METHODS A systematic review of PubMed/MEDLINE and EMBASE databases was performed using the Preferred Reporting Items for Systematic Reviews and MetaAnalyses(PRISMA) guidelines and checklist. Level III in vivo and in vitro studies examining PRP effects on muscles, myocytes and/or myoblasts were eligible for inclusion. Extracted data included PRP preparation methods and study results.RESULTS Twenty-three studies were included(15 in vivo, 6 in vitro, 2 in vitro/in vivo). Only one reported a complete PRP cytology(platelets, and red and white blood cell counts). Five in vitro studies reported increased cellular proliferation, four reported increased gene expression, and three reported increased cellular differentiation. Five in vivo studies reported increased gene expression, three reported superior muscle regeneration, and seven reported improved histological quality of muscular tissue.CONCLUSION The basic science literature on the use of PRP in muscle pathology demonstrates that PRP treatment confers several potentially beneficial effects on healing in comparison to controls. Future research is needed to determine optimal cytology,dosing, timing, and delivery methods of PRP for muscle pathologies. | Kyle N Kunze Charles P Hannon Jared D Fialkoff Rachel M Frank Brian J Cole | 2019 | World Journal of Orthopedics2019，10，7： | 6 |
| 7 | 2,4,6-trinitrobenzene sulfonic acid-induced chronic colitis with fibrosis and modulation of TGF-β1 signaling显示文摘AIM:To investigate whether targeting proteasome might reverse intestinal fibrosis in rats.METHODS:Chronic colitis was induced in rats by repeated administration of increasing dose of2,4,6-trinitrobenzene sulfonic acid(TNBS,15,30,45,60,60,60 mg)by rectal injection for 6 wk(from day0 to day 35),while control rats received the vehicle.TNBS+bortezomib(BTZ)rats received intraperitoneal injections of BTZ twice weekly(from day 37 to day44)at a dose of 25 mg/kg,whereas the control and TNBS groups received the same amount of the vehicle.Histologic scoring of inflammation and fibrosis was performed.Colonic production of transforming growth factor(TGF)-βwas measured by ELISA.Colon fibrosisrelated proteins such as phospho-p38,phosphoSMAD2/3,Akt and peroxisome proliferator activated receptorγ(PPARγ)were studied by western blot.Expression of the tight junction proteins,occludin and claudin-1,were assessed by Western blot.Colon proteasome activities(chymotrypsin-like and trypsinlike activities)were assessed.RESULTS:TNBS-treated rats had a higher colon weight/length ratio compared to control rats(P<0.01).Furthermore,fibrosis and inflammation scores were higher in TNBS-treated rats compared to control rats(P<0.01 for both).Colonic production of TGF-βproduction tended to be higher in TNBS-treated rats(P<0.06).Fibrosis-related proteins such as phospho-p38,phospho-SMAD2/3,and PPARγwere significantly higher in TNBS-treated rats compared to control rats(all P<0.05).TNBS rats had a higher expression of Akt compared to control rats(P<0.01).Tight junction proteins were modified by repeated TNBS challenge:colon occludin expression rose significantly(P<0.01),whereas claudin-1 expression fell(P<0.01).Bortezomib inhibition significantly decreased chymotrypsin-like activity(P<0.05),but had no significant effect on trypsin-like activity(P>0.05).In contrast,bortezomib had no effect on other studied parameters such as fibrosis score,TGF-βsignaling,or tight junction expression(P>0.05 for all).CONCLUSION:Rats with TNBS-induced chronic colitis exhibited colon fibrosis associated with higher TGF-βsignaling.Proteasome inhibition by bortezomib had no effect on fibrosis in our experimental conditions. | Emilien Loeuillard Julien Bertrand Anni Herranen Chloé Melchior Charlène Guérin Mo?se Co?ffier Moutaz Aziz Pierre Déchelotte Guillaume Savoye Rachel Marion-Letellier | 2014 | World Journal of Gastroenterology2014，20，48： | 4 |
| 8 | Rho A signaling and blood pressure: The consequence of failing to “Tone it Down”显示文摘Uncontrolled high blood pressure is a major risk factor for heart attack, stroke, and kidney failure and contributes to an estimated 25% of deaths worldwide. Despite numerous treatment options, estimates project that reasonable blood pressure(BP) control is achieved in only about half of hypertensive patients. Improvements in the detection and management of hypertension will undoubtedly be accomplished through a better understanding of the complex etiology of this disease and a more comprehensive inventory of the genes and genetic variants that influence BP regulation. Recent studies(primarily in pre-clinical models) indicate that the small GTPase Rho A and its downstream target, Rho kinase, play an important role in regulating BP homeostasis. Herein, we summarize the underlying mechanisms and highlight signaling pathways and regulators that impart tight spatial-temporal control of Rho A activity. We also discuss known allelic variations in the Rho A pathway and consider how these polymorphisms may affect genetic risk for hypertension and its clinical manifestations. Finally, we summarize the current(albeit limited) clinical data on the efficacy of targeting the Rho A pathway in hypertensive patients. | Xue Bai Rachel Dee Kevin D Mangum Christopher P Mack Joan M Taylor | 2016 | World Journal of Hypertension2016，6，1： | 3 |
| 9 | A prospective trial of volumetric intensity-modulated arc therapy vs conventional intensity modulated radiation therapy in advanced head and neck cancer显示文摘AIM: To prospectively compare volumetric intensitymodulated arc therapy(VMAT) and conventional intensity-modulated radiation therapy(IMRT) in coverage of planning target volumes and avoidance of multiple organs at risk(OARs) in patients undergoing definitive chemoradiotherapy for advanced(stage Ⅲ or Ⅳ)squamous cell cancer of the head and neck. METHODS: Computed tomography scans of 20 patients with advanced tumors of the larynx, naso-, oroand hypopharynx were prospectively planned using IMRT(7 field) and VMAT using two arcs. Calculated doses to planning target volume(PTV) and OAR were compared between IMRT and VMAT plans. Dose-volume histograms(DVH) were utilized to obtain calculated doses to PTV and OAR, including parotids, cochlea,spinal cord, brainstem, anterior tongue, pituitary and brachial plexus. DVH's for all structures were compared between IMRT and VMAT plans. In addition the planswere compared for dose conformity and homogeneity. The final treatment plan was chosen by the treating radiation oncologist. RESULTS: VMAT was chosen as the ultimate plan in 18 of 20 patients(90%) because the plans were thought to be otherwise clinically equivalent. The IMRT plan was chosen in 2 of 20 patients because the VMAT plan produced concentric irradiation of the cord which was not overcome even with an avoidance structure. For all patients, VMAT plans had a lower number of average monitor units on average(MU = 542.85) than IMRT plans(MU = 1612.58)(P < 0.001). Using the conformity index(CI), defined as the 95% isodose volume divided by the PTV, the IMRT plan was more conformal with a lower conformity index(CI = 1.61) than the VMAT plan(CI = 2.00)(P = 0.003). Dose homogeneity, as measured by average standard deviation of dose distribution over the PTV, was not different with VMAT(1.45 Gy) or IMRT(1.73 Gy)(P = 0.069). There were no differences in sparing organs at risk.CONCLUSION: In this prospective study, VMAT plans were chosen over IMRT 90% of the time. Compared to IMRT, VMAT plans used only one third of the MUs, had shorter treatment times, and similar sparing of OAR. Overall, VMAT provided similar dose homogeneity but less conformity in PTV irradiation compared to IMRT. This difference in conformity was not clinically significant. | Simon D Fung-Kee-Fung Rachel Hackett Lee Hales Graham Warren Anurag K Singh | 2012 | World Journal of Clinical Oncology2012，3，4： | 2 |
