| 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 | Direct anterior total hip arthroplasty: Literature review of variations in surgical technique显示文摘The direct anterior approach to the hip has been suggested to have several advantages compared to previously popular approaches through its use of an intra-muscular and intra-nervous interval betweenthe tensor fasciae latae and sartorius muscles. Recent increased interest in tissue-sparing and minimallyinvasive arthroplasty has given rise to a sharp increase in the utilization of direct anterior total hip arthroplasty. A number of variations of the procedure have been described and several authors have published their experiences and feedback to successfully accomplishing this procedure. Additionally, improved understanding of relevant soft tissue constraints and anatomic variants has provided improved margin of safety for patients. The procedure may be performed using speciallydesigned instruments and a fracture table, however many authors have also described equally efficacious performance using a regular table and standard arthroplasty tools. The capacity to utilize fluoroscopy intraoperatively for component positioning is a valuable asset to the approach and can be of particular benefit for surgeons gaining familiarity. Proper management of patient and limb positioning are vital to reducing risk of intra-operative complications. An understanding of its limitations and challenges are also critical to safe employment. This review summarizes the key features of the direct anterior approach for total hip arthroplasty as an aid to improving the understanding of this important and effective method for modern hip replacement surgeons. | Keith P Connolly Atul F Kamath | 2016 | World Journal of Orthopedics2016，7，1： | 33 |
| 4 | Mesenteric ischemia:Pathogenesis and challengingdiagnostic and therapeutic modalities显示文摘Mesenteric ischemia(MI) is an uncommon medical condition with high mortality rates. ΜΙ includes inadequate blood supply, inflammatory injury and eventually necrosis of the bowel wall. The disease can be divided into acute and chronic MI(CMI), with the first being subdivided into four categories. Therefore, acute MI(AMI) can occur as a result of arterial embolism, arterial thrombosis, mesenteric venous thrombosis and nonocclusive causes. Bowel damage is in proportion to the mesenteric blood flow decrease and may vary from minimum lesions, due to reversible ischemia, to transmural injury, with subsequent necrosis and perforation. CMI is associated to diffuse atherosclerotic disease in more than 95% of cases, with all major mesenteric arteries presenting stenosis or occlusion. Because of a lack of specific signs or due to its sometime quiet presentation, this condition is frequently diagnosed only at an advanced stage. Computed tomography(CT) imaging and CT angiography contribute to differential diagnosis and management of AMI. Angiography is also the criterion standard for CMI, with mesenteric duplex ultrasonography and magnetic resonance angiography also being of great importance. Therapeutic approach of MI includes both medical and surgical treatment. Surgical procedures include restoration of the blood flow with arteriotomy, endarterectomy or anterograde bypass, while resection of necrotic bowel is always implemented. The aim of this review was to evaluate the results of surgical treatment for MI and to present the recent literature in order to provide an update on the current concepts of surgical management of the disease. Mesh words selected include MI, diagnostic approach and therapeutic management. | Aikaterini Mastoraki Sotiria Mastoraki Evgenia Tziava Stavroula Touloumi Nikolaos Krinos Nikolaos Danias Andreas Lazaris Nikolaos Arkadopoulos | 2016 | World Journal of Gastrointestinal Pathophysiology2016，7，1： | 23 |
| 5 | Classification–coordination–collaboration:a systems approach for advancing Sustainable Development Goals显示文摘It is an urgent task to advance Sustainable Development Goals(SDGs)on different scales in the world.We propose a systems approach to combat this issue,namely‘classification–coordination–collaboration’.This approach allows SDGs to realize key breakthroughs over the short-term while achieving sweeping progress over the long run. | Bojie Fu Junze Zhang Shuai Wang Wenwu Zhao | 2020 | National Science Review2020，7，5： | 20 |
| 6 | Colorectal liver metastases:An update on multidisciplinary approach显示文摘Liver metastasis is the commonest form of distant metastasis in colorectal cancer.Selection criteria for surgery and liver-directed therapies have recently been extended.However,resectability remains poorly defined.Tumour biology is increasingly recognized as an important prognostic factor;hence molecular profiling has a growing role in risk stratification and management planning.Surgical resection is the only treatment modality for curative intent.The most appropriate surgical approach is yet to be established.The primary cancer and the hepatic metastasis can be removed simultaneously or in a two-step approach;these two strategies have comparable long-term outcomes.For patients with a limited future liver remnant,portal vein embolization,combined ablation and resection,and associating liver partition and portal vein ligation for staged hepatectomy have been advocated,and each has their pros and cons.The role of neoadjuvant and adjuvant chemotherapy is still debated.Targeted biological agents and loco-regional therapies(thermal ablation,intra-arterial chemo-or radio-embolization,and stereotactic radiotherapy) further improve the already favourable results.The recent debate about offering liver transplantation to highly selected patients needs validation from large clinical trials.Evidencebased protocols are missing,and therefore optimal management of hepatic metastasis should be personalized and determined by a multi-disciplinary team. | Felix Che-Lok Chow Kenneth Siu-Ho Chok | 2019 | World Journal of Hepatology2019，11，2： | 20 |
| 7 | Shift to a low carbon society through energy systems design显示文摘Concern about global warming calls for an advanced approach for designing an energy system to reduce carbon emissions as well as to secure energy security for each country.Conventional energy systems tend to introduce different technologies with high conversion efficiency,leading to a higher average efficiency.Advanced energy systems can be achieved not by an aggregate form of conversion technologies but by an innovative system design itself.The concept of LCS(low carbon society) is a unique approach having multi-dimensional considerations such as social,economic and environmental dimensions.The LCS aims at an extensive restructuring of worldwide energy supply/demand network system by not only replacing the conventional parts with the new ones,but also integrating all the necessary components and designing absolutely different energy networks.As a core tool for the LCS design,energy-economic models are applied to show feasible solutions in future with alternatives such as renewable resources,combined heat and power,and smart grid operations.Models can introduce changes in energy markets,technology learning in capacity,and penetration of innovative technologies,leading to an optimum system configuration under priority settings.The paper describes recent trials of energy models application related to waste-to-energy,clean coal,transportation and rural development.Although the modelling approach is still under investigation,the output clearly shows possible options having variety of technologies and linkages between supply and demand sides.Design of the LCS means an energy systems design with the modelling approach,which gives solution for complex systems,choices among technologies,technology feasibility,R&D targets,and what we need to start. | Toshihiko NAKATA Mikhail RODIONOV Diego SILVA Joni JUPESTA | 2010 | Science China(Technological Sciences)2010，53，1： | 19 |
| 8 | Management of distal humeral coronal shear fractures显示文摘Coronal shear fractures of the distal humerus are rare,complex fractures that can be technically challenging to manage. They usually result from a low-energy fall and direct compression of the distal humerus by the radial head in a hyper-extended or semi-flexed elbow or from spontaneous reduction of a posterolateral subluxation or dislocation. Due to the small number of soft tissue attachments at this site, almost all of these fractures are displaced. The incidence of distal humeral coronal shear fractures is higher among women because of the higher rate of osteoporosis in women and the difference in carrying angle between men and women. Distal humeral coronal shear fractures may occur in isolation, may be part of a complex elbow injury, or may be associated with injuries proximal or distal to the elbow. An associated lateral collateral ligament injury is seen in up to 40% and an associated radial head fracture is seen in up to 30% of these fractures. Given the complex nature of distal humeral coronal shear fractures, there is preference for operative management. Operative fixation leads to stable anatomic reduction, restores articular congruity, and allows initiation of early range-of-motion movements in the majority of cases. Several surgical exposure and fixation techniques are available to reconstruct the articular surface fol owing distal humeral coronal shear fractures. The lateral extensile approach and fixation with countersunk headless compression screws placed in an anterior-to-posterior fashion are commonly used. We have found a two-incision approach(direct anterior and lateral) that results in less soft tissue dissection and better outcomes than the lateral extensile approach in our experience. Stiffness, pain, articular incongruity, arthritis, and ulnohumeral instability may result if reduction is non-anatomic or if fixation fails. | Shahram S Yari Nathan L Bowers Miguel A Craig Lee M Reichel | 2015 | World Journal of Clinical Cases2015，3，5： | 15 |

| 10 | Layout Optimization for the Dishes Installed on a Rotating Table——The Packing Problem With Equilibrium Behavioural Constraints显示文摘The layout optimization for the dishes installed on a rotating table is investigated. This is a packing problem with equilibrium behavioural constraints. To deal with its layout topo-models and initial layout, a mathematical model and heuristic approaches, including the method of model-changing iteration (MCI) and the method of main objects topo-models (MOT), are proposed, with a series of intuitive algorithms embedded in, such as the technique for the search under the initial guess and the strategies for remission of 'combinatorial explosion' . The validity and reliability of the proposed algorithms are verified by numerical examples and engineering applications, which could be used in satellite module, multiple spindle box, rotating structure and so on. | 滕弘飞 孙守林 葛文海 钟万勰 | 1994 | Science China Mathematics1994，37，10： | 14 |
| 11 | mTOR signaling in skeletal development and disease显示文摘The mammalian/mechanistic target of rapamycin(m TOR) is a serine/threonine protein kinase that integrates inputs from nutrients and growth factors to control many fundamental cellular processes through two distinct protein complexes m TORC1 and m TORC2.Recent mouse genetic studies have established that m TOR pathways play important roles in regulating multiple aspects of skeletal development and homeostasis. In addition, m TORC1 has emerged as a common effector mediating the bone anabolic effect of Igf1,Wnt and Bmp. Dysregulation of m TORC1 could contribute to various skeletal diseases including osteoarthritis and osteoporosis.Here we review the current understanding of m TOR signaling in skeletal development and bone homeostasis, as well as in the maintenance of articular cartilage. We speculate that targeting m TOR signaling may be a valuable approach for treating skeletal diseases. | Jianquan Chen Fanxin Long | 2018 | Bone Research2018，6，1： | 14 |
| 12 | Direct anterior total hip arthroplasty:Comparative outcomes and contemporary results显示文摘Direct anterior total hip arthroplasty has become increasingly more popular among arthroplasty surgeons,in large part due to the use of an intramuscular interval and desire to reduce soft tissue damage.Several studies have now been published comparing the anterior intramuscular to other commonly used approaches,and many studies have published complication rates on large series of patients.Review of comparative studies indicates direct anterior hips tend towards shorter hospital stays and high rates of patients discharged to home.Although some studies show evidence of early benefit in functional outcomes,there is no strong evidence that the anterior approach provides any long term functional improvements compared to other approaches.Additionally,evidence to support reduced damage to soft tissue may not translate to certain clinical significance.Rates of intra-operative femur fracture,operative time and blood loss rates are notably higher for those developing familiarity with this approach.However,when surgeons have performed a modest number of procedures,the complication rates tend to markedly decrease in most studies to levels comparable to other approaches.Accuracy of component positioning also favors the anterior approach in some studies.This review summarizes the available literature comparing the direct anterior to other approaches for total hip arthroplasty and provides a comprehensive summary of common complications. | Keith P Connolly Atul F Kamath | 2016 | World Journal of Orthopedics2016，7，2： | 14 |

| 14 | Posterior approach (Kraske procedure) for surgical treatment of presacral tumors显示文摘Presacral tumors are rare,but can comprise a great variety of histological types.Congenital tumors are the most common.Once the diagnosis is established,surgical resection is essential because of the potential for malignancy or infection.Previous biopsy is not necessary or may be even harmful.To decide the best surgical approach(abdominal,sacral or combined) an individual and multidisciplinary analysis must be carried out.We report three cases of cystic presacral masses in which a posterior approach(Kraske procedure) enabled complete resection,the only way to decrease local recurrence.All patients had a satisfactory recovery.A brief overview of retrorectal tumors is presented,focusing on classification,clinical presentation,diagnosis and surgical management. | José Manuel Aranda-Narváez Antonio Jesús GonzálezSánchez Custodia Montiel-Casado Belinda Sánchez-Pérez Carolina Jiménez-Mazure Marta Valle-Carbajo Julio Santoyo-Santoyo | 2012 | World Journal of Gastrointestinal Surgery2012，4，5： | 12 |
| 15 | Testing Serial Correlation in Partially Linear Additive Models显示文摘As an extension of partially linear models and additive models, partially linear additive model is useful in statistical modelling. This paper proposes an empirical likelihood based approach for testing serial correlation in this semiparametric model. The proposed test method can test not only zero first-order serial correlation, but also higher-order serial correlation. Under the null hypothesis of no serial correlation, the test statistic is shown to follow asymptotically a chi-square distribution. Furthermore, a simulation study is conducted to illustrate the performance of the proposed method. | Jin YANG Chuan-hua WEI | 2019 | Acta Mathematicae Applicatae Sinica2019，35，2： | 12 |
| 16 | Bipolar hemiarthroplasty for femoral neck fracture using the direct anterior approach显示文摘AIM: To evaluate whether walking ability recovers early after bipolar hemiarthroplasty(BHA) using a direct anterior approach.METHODS: Between 2008 and 2010, 81 patients with femoral neck fracture underwent BHA using the direct anterior approach(DAA) or the posterior approach(PA). The mean observation period was 36 mo. The age, sex, body mass index(BMI), time from admission to surgery, length of hospitalization, outcome after discharge, walking ability, duration of surgery, blood loss and complications were compared. RESULTS: There was no significant difference in the age, sex, BMI, time from admission to surgery, length of hospitalization, outcome after discharge, duration of surgery and blood loss between the two groups. Two weeks after the operation, assistance was not necessary for walking in the hospital in 65.0% of the patients in the DAA group and in 33.3% in the PA group(P < 0.05). As for complications, fracture of the femoral greater trochanter developed in 1 patient in the DAA group and calcar crack and dislocation in 1 patient each in the PA group.CONCLUSION: DAA is an approach more useful for BHA for femoral neck fracture in elderly patients than total hip arthroplasty in terms of the early acquisition of walking ability. | Tomonori Baba Katsuo Shitoto Kazuo Kaneko | 2013 | World Journal of Orthopedics2013，4，2： | 11 |
| 17 | Treatment strategies for colorectal carcinoma with synchronous liver metastases: Which way to go?显示文摘AIM: To offer an up-to-date review of all availabletreatment strategies for patients with synchronous colorectal liver metastases(CLM).METHODS: A comprehensive literature search was performed to identify articles related to the management of patients with synchronous CLM. A search of the electronic databases PubMed, MEDLINE, and Google Scholar was conducted in September 2014.The following search terms were used: synchronous colorectal liver metastases, surgery, stage Ⅳ colorectal cancer, liver-first approach, and up-front hepatectomy.These terms were employed in various combinations to maximize the search. Only articles written in English were included. Particular attention was devoted to studies and review articles that were published within the last six years(2009-2014). Additional searches of the cited references from primary articles were performed to further improve the review. The full texts of all relevant articles were accessed by two independent reviewers.RESULTS: Poor long-term outcomes of patients with synchronous CLM managed by a traditional treatment strategy have led to questions about the timing and sequence of possible therapeutic interventions. Thus,alternative paradigms called reverse strategies have been proposed. Presently, there are four treatment strategies available:(1) primary first approach(or traditional approach) comprises resection of the primary colorectal tumor followed by chemotherapy;subsequent liver resection is performed 3-6 mo after colorectal resection(provided that CLM are still resectable);(2) simultaneous resection of the primary colorectal tumor and CLM during a single operation presents intriguing options for a highly select group of patients, which can be associated with significant postoperative morbidity;(3) liver-first(or chemotherapy-first) approach comprises preoperative chemotherapy(3-6 cycles) followed by liver resection,adjuvant chemotherapy, and resection of the primary colorectal tumor(it is best suited for patients withasymptomatic primary tumors and initially unresectable or marginally resectable CLM); and(4) up-front hepatectomy(or 'true' liver-first approach) includes liver resection followed by adjuvant chemotherapy,colorectal resection, and adjuvant chemotherapy(strategy can be offered to patients with asymptomatic primary tumors and initially resectable CLM).CONCLUSION: None of the aforementioned strategies appears inferior. It is necessary to establish individual treatment plans in multidisciplinary team meetings through careful appraisal of all strategies. | Peter Ihnát Petr Vávra Pavel Zonca | 2015 | World Journal of Gastroenterology2015，21，22： | 10 |
| 18 | Integrated approach to colorectal anastomotic leakage: Communication, infection and healing disturbances显示文摘Colorectal anastomotic leakage(CAL) remains a major complication after colorectal surgery. Despite all efforts during the last decades, the incidence of CAL has not decreased. In this review, we summarize the available strategies regarding prevention, prediction and intervention of CAL and categorize them into three categories: communication, infection and healing disturbances. These three major factors actively interact during the onset of CAL. We aim to provide an integrated approach to CAL based on its etiology. The intraoperative air leak test, intraoperative endoscopy, radiological examinations and stoma construction mainly aim to detect and to prevent communication between the intra- and extra-luminal content. Other strategies including postoperative drainage, antibiotics, and infectious-parameter evaluation are intended to detect and prevent anastomotic or peritoneal infection. Most currently available interventions for CAL focus on the control of communication and infection, while strategies targeting the healing disturbances such as lifestyle changes, oxygen therapy and evaluation of metabolic biomarkers still lack wide clinical application. This simplified categorization may contribute to an integrated understanding of CAL. We strongly believe that this integrated approach should be taken into consideration during clinical practice. An integrated approach to CAL could contribute to a better understanding of the etiology of CAL and eventually better patient outcome. | Cloe L Sparreboom Zhou-Qiao Wu Jia-Fu Ji Johan F Lange | 2016 | World Journal of Gastroenterology2016，22，32： | 9 |
| 19 | Biomimetic delivery of signals for bone tissue engineering显示文摘Bone tissue engineering is an exciting approach to directly repair bone defects or engineer bone tissue for transplantation.Biomaterials play a pivotal role in providing a template and extracellular environment to support regenerative cells and promote tissue regeneration. A variety of signaling cues have been identified to regulate cellular activity, tissue development, and the healing process. Numerous studies and trials have shown the promise of tissue engineering, but successful translations of bone tissue engineering research into clinical applications have been limited, due in part to a lack of optimal delivery systems for these signals. Biomedical engineers are therefore highly motivated to develop biomimetic drug delivery systems, which benefit from mimicking signaling molecule release or presentation by the native extracellular matrix during development or the natural healing process. Engineered biomimetic drug delivery systems aim to provide control over the location, timing, and release kinetics of the signal molecules according to the drug's physiochemical properties and specific biological mechanisms. This article reviews biomimetic strategies in signaling delivery for bone tissue engineering, with a focus on delivery systems rather than specific molecules. Both fundamental considerations and specific design strategies are discussed with examples of recent research progress, demonstrating the significance and potential of biomimetic delivery systems for bone tissue engineering. | Ming Dang Laura Saunders Xufeng Niu Yubo Fan Peter X.Ma | 2018 | Bone Research2018，6，3： | 9 |
