| 1 | Anterior muscle sparing approach for total hip arthroplasty显示文摘The purpose of this review is to examine the validity of positive claims regarding the direct anterior approach(DAA) with a fracture table for total hip arthroplasty. Recent literature regarding the DAA was searched and specific claims investigated including improved early outcomes, speed of recovery, component placement, dislocation rates, and complication rates. Recent literature is positive regarding the effects of total hip arthroplasty with the anterior approach. While the data is not definitive at present, patients receiving the anterior approach for total hip arthroplasty tend to recover more quickly and have improved early outcomes. Component placement with the anterior approach is more often in the 'safe zone' than with other approaches. Dislocation rates tend to be less than 1% with the anterior approach. Complication rates vary widely in the published literature. A possible explanation is that the varianceis due to surgeon and institutional experience with the anterior approach procedure. Concerns remain regarding the 'learning curve' for both surgeons and institutions. In conclusion, it is not a matter of should this approach be used, but how should it be implemented. | Joseph T Moskal Susan G Capps John A Scanelli | 2013 | World Journal of Orthopedics2013，4，1： | 47 |

| 3 | Role of liver transplantation in the management of hepatoblastoma in the pediatric population显示文摘Hepatoblastoma(HB) is the most common primary liver tumor in children and accounts for two-thirds of all malignant liver neoplasms in the pediatric population. For patients with advanced HB(unresectable or unresponsive to chemotherapy), combined treatment with chemotherapy and liver transplantation is an excellent option. The etiology of HB is mostly obscure because of its extreme rarity although some inherited syndromes and very low birth weight have been associated with it. The prognosis for children with HB has significantly improved in the past three decades thanks to advancements in chemotherapy, surgical resection and postoperative care. In 2002 a surgical staging system called pretreatment extent of disease(PRETEXT) was designed to allow a universal, multidisciplinary approach to patients with HB. Between one-third to two-thirds of patients initially present with unresectable tumors or distant metastases, but up to 85% of these tumors become operable after neoadjuvant chemotherapy. Patients with PRETEXT categories 1, 2, and some 3 are referred for neoadjuvant chemotherapy followed by surgical resection with the goal of complete tumor removal. Classic treatments regimens include a combination of cisplatin, fluorouracil, and vincristine or cisplatin and doxorubicin. Liver transplantation is the only treatment option for unresectable HB. In 2010 the pediatric end-stage liver disease, a pediatric-specific scoring system that determines a patient's ranking on the liver transplant list, began to award additional 'exception' points for patients with HB. We analyzed the Standard Transplant Analysis and Research dataset to assess the impact of changes in exception point criteria for HB on outcomes after liver transplantation at Texas Children's Hospital in Houston, Texas. We found that patients who were listed for transplantation with current HB exception criteria experienced a shorter waitlist time but survival was similar between the two eras. | Saira Khaderi Jacfranz Guiteau Ronald T Cotton Christine O'Mahony Abbas Rana John A Goss | 2014 | World Journal of Transplantation2014，4，4： | 23 |
| 4 | Historically significant events in the discovery of RANK/RANKL/OPG显示文摘After it was suggested 30 years ago that the osteoblast lineage controlled the formation of osteoclasts, methods were developed that established this to be the case, but the molecular controls were elusive. Over more than a decade much evidence was obtained for signaling mechanisms that regulated the production of a membrane- bound regulator of osteoclastogenesis, in the course of which intercellular communication in bone was revealed in its complexity. The discovery of regulation by tumor necrosis factor ligand and receptor families was made in the last few years of the twentieth century, leading since then to a new physiology of bone, and to exciting drug development. | T John Martin | 2013 | World Journal of Orthopedics2013，4，4： | 21 |
| 5 | Necrotizing enterocolitis: A multifactorial disease with no cure显示文摘Necrotizing enterocolitis is an inflammatory bowel disease of neonates with significant morbidity and mortality in preterm infants. Due to the multifactorial nature o the disease and limitations in disease models, early diagnosis remains challenging and the pathogenesis elusive. Although preterm birth, hypoxic-ischemic events formula feeding, and abnormal bacteria colonization are established risk factors, the role of genetics and vasoactive/inflammatory mediators is unclear Consequently, treatments do not target the specific underlying disease processes and are symptomatic and surgically invasive. Breast-feeding is the most effective preventative measure. Recent advances in the prevention of necrotizing enterocolitis have focused on bioactive nutrients and trophic factors in human milk. Developmen of new disease models including the aspect of prematurity that consistently predisposes neonates to the disease with multiple risk factors will improve our understanding of the pathogenesis and lead to discovery of innovative therapeutics. | Kareena L Schnabl John E Van Aerde Alan BR Thomson Michael T Clandinin | 2008 | World Journal of Gastroenterology2008，14，14： | 19 |
| 6 | Visceral hypersensitivity and electromechanical dysfunction as therapeutic targets in pediatric functional dyspepsia显示文摘Functional gastrointestinal disorders(FGID) are common clinical syndromes diagnosed in the absence of biochemical,structural,or metabolic abnormalities. They account for significant morbidity and health care expenditures and are identifiable across variable age,geography,and culture. Etiology of abdominal pain associated FGIDs,including functional dyspepsia(FD),remains incompletely understood,but growing evidence implicates the importance of visceral hypersensitivity and electromechanical dysfunction. This manuscript explores data supporting the role of visceral hypersensitivity and electromechanical dysfunction in FD,with focus on pediatric data when available,and provides a summary of potential therapeutic targets. | John M Rosen Jose T Cocjin Jennifer V Schurman Jennifer M Colombo Craig A Friesen | 2014 | World Journal of Gastrointestinal Pharmacology and Therapeutics2014，5，3： | 16 |

| 8 | Comparison of esophageal capsule endoscopy and esophagogastroduodenoscopy for diagnosis of esophageal varices显示文摘AIM: To investigate the utility of esophageal capsule endoscopy in the diagnosis and grading of esophageal varices. METHODS: Cirrhotic patients who were undergo-ing esophagogastroduodenoscopy (EGD) for variceal screening or surveillance underwent capsule endos-copy. Two separate blinded investigators read each capsule endoscopy for the following results: variceal grade, need for treatment with variceal banding or prophylaxis with beta-blocker therapy, degree of portal hypertensive gastropathy, and gastric varices. RESULTS: Fifty patients underwent both capsule and EGD. Forty-eight patients had both procedures on the same day, and 2 patients had capsule endoscopy within 72 h of EGD. The accuracy of capsule endos- copy to decide on the need for prophylaxis was 74%, with sensitivity of 63% and specificity of 82%. Inter-rater agreement was moderate (kappa = 0.56). Agree-ment between EGD and capsule endoscopy on grade of varices was 0.53 (moderate). Inter-rater reliability was good (kappa = 0.77). In diagnosis of portal hyper-tensive gastropathy, accuracy was 57%, with sensitiv-ity of 96% and specificity of 17%. Two patients had gastric varices seen on EGD, one of which was seen on capsule endoscopy. There were no complications from capsule endoscopy.CONCLUSION: We conclude that capsule endoscopy has a limited role in deciding which patients would benefit from EGD with banding or beta-blocker thera-py. More data is needed to assess accuracy for staging esophageal varices, PHG, and the detection of gastric varices. | Catherine T Frenette John G Kuldau Donald J Hillebrand Jill Lane Paul J Pockros | 2008 | World Journal of Gastroenterology2008，14，28： | 7 |
| 9 | Hematological disorders and pulmonary hypertension显示文摘Pulmonary hypertension(PH),a serious disorder with a high morbidity and mortality rate,is known to occur in a number of unrelated systemic diseases.Several hematological disorders such as sickle cell disease,thalassemia and myeloproliferative diseases develop PH which worsens the prognosis.Associated oxidant injury and vascular inflammation cause endothelial damage and dysfunction.Pulmonary vascular endothelial damage/dysfunction is an early event in PH resulting in the loss of vascular reactivity,activation of proliferative and antiapoptotic pathways leading to vascular remodeling,elevated pulmonary artery pressure,right ventricular hypertrophy and premature death.Hemolysis observed in hematological disorders leads to free hemoglobin which rapidly scavenges nitric oxide(NO),limiting its bioavailability,and leading to endothelial dysfunction.In addition,hemolysis releases arginase into the circulation which converts L-arginine to ornithine,thus bypassing NO production.Furthermore,treatments for hematological disorders such as immunosuppressive therapy,splenectomy,bone marrow transplantation,and radiation have been shown to contribute to the development of PH.Recent studies have shown deregulated iron homeostasis in patients with cardiopulmonary diseases including pulmonary arterial hypertension(PAH).Several studies have reported low iron levels in patients with idiopathic PAH,and iron deficiency is an important risk factor.This article reviews PH associated with hematological disorders and its mechanism:and iron homeostasis and its relevance to PH. | Rajamma Mathew Jing Huang Joseph M Wu John T Fallon Michael H Gewitz | 2016 | World Journal of Cardiology2016，8，12： | 6 |

| 12 | Clinical outcomes following salvage Gamma Knife radiosurgery for recurrent glioblastoma显示文摘Glioblastoma multiforme(GBM) is the most common malignant primary brain tumor with a survival prognosis of 14-16 mo for the highest functioning patients. Despite aggressive, multimodal upfront therapies, the majority of GBMs will recur in approximately six months. Salvage therapy options for recurrent GBM(r GBM) are an area of intense research. This study compares recent survival and quality of life outcomes following Gamma Knife radiosurgery(GKRS) salvage therapy. Following a Pub Med search for studies usingGKRS as salvage therapy for malignant gliomas, nine articles from 2005 to July 2013 were identified which evaluated rG BM treatment. In this review, we compare overall survival following diagnosis, overall survival following salvage treatment, progression-free survival, time to recurrence, local tumor control, and adverse radiation effects. This report discusses results for rG BM patient populations alone, not for mixed populations with other tumor histology grades. All nine studies reported median overall survival rates(from diagnosis, range:16.7-33.2 mo; from salvage, range:9-17.9 mo). Three studies identified median progression-free survival(range:4.6-14.9 mo). Two showed median time to recurrence of GBM. Two discussed local tumor control. Six studies reported adverse radiation effects(range:0%-46% of patients). The greatest survival advantages were seen in patients who received GKRS salvage along with other treatments, like resection or bevacizumab, suggesting that appropriately tailored multimodal therapy should be considered with each rG BM patient. However, there needs to be a randomized clinical trial to test GKRS for rG BM before the possibility of selection bias can be dismissed. | Erik W Larson Halloran E Peterson Wayne T Lamoreaux Alexander R MacKay Robert K Fairbanks Jason A Call Jonathan D Carlson Benjamin C Ling John J Demakas Barton S Cooke Christopher M Lee | 2014 | World Journal of Clinical Oncology2014，5，2： | 5 |

| 14 | Mechanical and cellular processes driving cervical myelopathy显示文摘Cervical myelopathy is a well-described clinical syndrome that may evolve from a combination of etiological mechanisms. It is traditionally classified by cervical spinal cord and/or nerve root compression which varies in severity and number of levels involved. The vast array of clinical manifestations of cervical myelopathy cannot fully be explained by the simple concept that a narrowed spinal canal causes compression of the cord, local tissue ischemia, injury and neurological impairment. Despite advances in surgical technology and treatment innovations, there are limited neuro-protective treatments for cervical myelopathy, which reflects an incomplete understanding of the pathophysiological processes involved in this disease. The aim of this review is to provide a comprehensive overview of the key pathophysiological processes at play in the development of cervical myelopathy. | Roisin T Dolan Joseph S Butler John M O'Byrne Ashley R Poynton | 2016 | World Journal of Orthopedics2016，7，1： | 5 |

| 18 | Efficacy and safety of liquid nitrogen cryotherapy for treatment of Barrett's esophagus显示文摘AIM To evaluate the efficacy and safety of liquid nitrogen cryotherapy as a primary or rescue treatment for BE,with and without dysplasia,or intramucosal adenocarcinoma (IMC).METHODS This was a retrospective,single-center study carried out in a tertiary care center including 45 patients with BE who was treatment-na?ve or who had persistent intestinal metaplasia(IM),dysplasia,or IMC despite prior therapy.Barrett's mucosa was resected via EMR when clinically appropriate,then patients underwent cryotherapy until eradication or until deemed to have failed treatment.Surveillance biopsies were taken at standard intervals.RESULTS From 2010 through 2014,33 patients were studied regarding the efficacy of cryotherapy.Overall,29 patients (88%) responded to cryotherapy,with 84% having complete regression of all dysplasia and cancer.Complete eradication of cancer and dysplasia was seen in 75% of subjects with IMC; the remaining two subjects did not respond to cryotherapy.Following cryotherapy,15 patients with high-grade dysplasia (HGD) had 30% complete regression,50% IM,and 7% low-grade dysplasia (LGD); one subject had persistent HGD.Complete eradication of dysplasia occurred in all 5 patients with LGD.In 5 patients with IM,complete regression occurred in 4,and IM persisted in one.In 136 cryotherapy sessions amongst 45 patients,adverse events included chest pain (1%),stricture (4%),and one gastrointestinal bleed in a patient on dual antiplatelet therapy who had previously undergone EMR.CONCLUSION Cryotherapy is an efficacious and safe treatment modality for Barrett's esophagus with and without dysplasia or intramucosal adenocarcinoma. | Kristen Suchniak-Mussari Charles E Dye Matthew T Moyer Abraham Mathew Thomas J McGarrity Eileen M Gagliardi Jennifer L Maranki John M Levenick | 2017 | World Journal of Gastrointestinal Endoscopy2017，9，9： | 4 |
| 19 | 全球药物滥用的疾病负担:来自2010年全球疾病负担研究显示文摘背景:直到目前还没有研究者系统地估计过全球及区域性的苯丙胺类、大麻、可卡因和阿片类药物依赖的患病率及其造成的疾病负担。我们旨在用伤残损失寿命年(YLDs)、过早死亡损失寿命年(YLLs)和伤残调整寿命年(DALYs)来估计药物依赖的患病率和其造成的疾病负担。方法:采用贝叶斯Meta回归的方法(Dis Mod-MR)对药物依赖的流行病学研究及2010年全球疾病、伤害及危险因素负担研究(GBD 2010)进行了系统综述,估计人群水平的药物依赖患病率。GBD 2010通过代表性社区调查和基于互联网的调查计算出新的失能权重。我们把估计的药物依赖患病率和新的失能权重结合起来估算药物依赖导致的YLDs、YLLs、DALYs和其作为相关疾病危险因素时导致的YLDs、YLLs和DALYs。结果:2010年,药物依赖直接造成了2千万的DALYs(95%UI(不确定区间)1.3-2.54千万),占全球全因DALYs的0.8%(0.6%-1.0%)。世界范围内,相比于其他药物,越来越多的人依赖于阿片类和苯丙胺类药物。阿片类药物依赖直接造成的疾病负担最大(DALYs为920万,95%UI为710-1140万)。在某些地区,药物依赖导致的DALYs所占比例比其他地区高出20倍,收入越高的国家药物依赖造成的负担所占比例也越高。注射吸毒所致HIV感染造成210万的DALYs(95%UI 110-360万),所致HCV感染导致50.2万的DALYs(95%UI 28.6-89.1万)。苯丙胺类药物依赖所致自杀造成85.4万的DALYs(95%UI 29.1-179.1万),阿片类药物依赖所致自杀造成67.1万的DALYs(95%UI 32.9-173.0万),可卡因依赖所致自杀造成32.4万的DALYs(95%UI 10.9-68.2万)。药物依赖导致的疾病负担最高的国家(>650 DALYs/10万人)包括美国,英国,俄罗斯和澳大利亚。结论:药物滥用是造成全球疾病负担的一个重要因素。为减少人群水平的疾病负担,我们需采取有效的措施(比如给予阿片类药物依赖者替代治疗及针具交换等)降低阿片类药物依赖和注射吸毒导致的疾病负担。 | 王同瑜 Degenhardt L Whiteford HA Ferrari AJ Baxter AJ Charlson FJ Hall WD Freedman G Burstein R Johns Engell RE Flaxman A Murray CJ Vos T | 2015 | 中国药物依赖性杂志2015，24，6： | 3 |
