| 1 | Solid pseudopapillary tumor of the pancreas:A review of 553 cases in Chinese literature显示文摘AIM:To sum up the clinical and pathological characte- ristics of solid pseudopapillary tumor (SPT) and the experience with it.METHODS: A total of 553 SPT patients reported in Chinese literature between January 1996 and January 2009 were retrospectively reviewed and analyzed. RESULTS: The mean age of the 553 SPT patients included in this review was 27.2 years, and the male to female ratio was 1:8.37. Their symptoms were non-specific, and nearly one third of the patients were asymptomatic. Computed tomography and ultraso-nography were performed to show the nature and location of SPT. Most of the tumors were distributed in the pancreatic head (39.8%), tail (24.1%), body andtail (19.5%). Forty-five patients (9.2%) were diagnosed as malignant SPT with metastasis or invasion. None of the clinical factors was closely related to the malignant potential of SPT. Surgery was the main therapeutic modality for SPT. Local resection, distal pancreatectomy and pancreatoduodenectomy were the most common surgical procedures. Local recurrence and hepatic metastasis were found in 11 and 2 patients, respectively, after radical resection. Four patients died of tumor progression within 4 years after palliative resection of SPT. The prognosis of SPT patients was good with a 5-year survival rate of 96.9%.CONCLUSION: SPT of the pancreas is a rare indolent neoplasm that typically occurs in young females. It is a low-grade malignancy and can be cured with extended resection. The prognosis of such patients is good although the tumor may recur and metastasize. | Yu, Peng-Fei Hu, Zhen-Hua Wang, Xin-Bao Guo, Jian-Min Cheng, Xiang-Dong Zhang, Yun-Li Xu, Qi | 2010 | World Journal of Gastroenterology2010，16，10： | 121 |
| 2 | Current status and progress of pancreatic cancer in China显示文摘Cancer is currently one of the most important public health problems in the world.Pancreatic cancer is a fatal disease with poor prognosis.As in most other countries,the health burden of pancreatic cancer in China is increasing,with annual mortality rates almost equal to incidence rates.The increasing trend of pancreatic cancer incidence is more significant in the rural areas than in the urban areas.Annual diagnoses and deaths of pancreatic cancer in China are now beyond the number of cases in the United States.GLOBOCAN 2012 estimates that cases in China account for 19.45%(65727/337872) of all newly diagnosed pancreatic cancer and 19.27%(63662/330391) of all deaths from pancreatic cancer worldwide.The population's growing socioeconomic status contributes to the rapid increase of China's proportional contribution to global rates.Here,we present an overview of control programs for pancreatic cancer in China focusing on prevention,early diagnosis and treatment.In addition,we describe key epidemiological,demographic,and socioeconomic differences between China and developed countries.Facts including no nationwide screening program for pancreatic cancer,delay in early detection resulting in a late stage at presentation,lack of awareness of pancreatic cancer in the Chinese population,and low investment compared with other cancer types by government have led to backwardness in China's pancreatic cancer diagnosis and treatment.Finally,we suggest measures to improve health outcomes of pancreatic cancer patients in China. | Quan-Jun Lin Feng Yang Chen Jin De-Liang Fu | 2015 | World Journal of Gastroenterology2015，21，26： | 93 |
| 3 | Current concepts on osteonecrosis of the femoral head显示文摘It is estimated that 20000 to 30000 new patients are diagnosed with osteonecrosis annually accounting for approximately 10% of the 250000 total hip arthroplasties done annually in the United States. Thelack of level 1 evidence in the literature makes it difficult to identify optimal treatment protocols to manage patients with pre-collapse avascular necrosis of the femoral head, and early intervention prior to collapse is critical to successful outcomes in joint preserving procedures. There have been a variety of traumatic and atraumatic factors that have been identified as risk factors for osteonecrosis, but the etiology and pathogenesis still remains unclear. Current osteonecrosis diagnosis is dependent upon plain anteroposterior and frog-leg lateral radiographs of the hip, followed by magnetic resonance imaging(MRI). Generally, the first radiographic changes seen by radiograph will be cystic and sclerotic changes in the femoral head. Although the diagnosis may be made by radiograph, plain radiographs are generally insufficient for early diagnosis, therefore MRI is considered the most accurate benchmark. Treatment options include pharmacologic agents such as bisphosphonates and statins, biophysical treatments, as well as joint-preserving and joint-replacing surgeries. the surgical treatment of osteonecrosis of the femoral head can be divided into two major branches: femoral head sparing procedures(FHSP) and femoral head replacement procedures(FHRP). In general, FHSP are indicated at pre-collapse stages with minimal symptoms whereas FHRP are preferred at post-collapse symptomatic stages. It is difficult to know whether any treatment modality changes the natural history of core decompression since the true natural history of core decompression has not been delineated. | Joaquin Moya-Angeler Arianna L Gianakos Jordan C Villa Amelia Ni Joseph M Lane | 2015 | World Journal of Orthopedics2015，6，8： | 94 |

| 5 | Clinical characteristics of novel coronavirus cases in tertiary hospitals in Hubei Province显示文摘Background:The 2019 novel coronavirus(2019-nCoV)causing an outbreak of pneumonia in Wuhan,Hubei province of China was isolated in January 2020.This study aims to investigate its epidemiologic history,and analyze the clinical characteristics,treatment regimens,and prognosis of patients infected with 2019-nCoV during this outbreak.Methods:Clinical data from 1372019-nCoV-infected patients admitted to the respiratory departments of nine tertiary hospitals in Hubei province from December 30,2019 to January 24,2020 were retrospectively collected,including general status,clinical manifestations,laboratory test results,imaging characteristics,and treatment regimens.Results:None of the 137 patients(61 males,76 females,aged 20-83 years,median age 57 years)had a definite history of exposure to Huanan Seafood Wholesale Market.Major initial symptoms included fever(112/137,81.8%),coughing(66/137,48.2%),and muscle pain or fatigue(44/137,32.1%),with other,less typical initial symptoms observed at low frequency,including heart palpitations,diarrhea,and headache.Nearly 80%of the patients had normal or decreased white blood cell counts,and 72.3%(99/137)had lymphocytopenia.Lung involvement was present in all cases,with most chest computed tomography scans showing lesions in multiple lung lobes,some of which were dense;ground-glass opacity co-existed with consolidation shadows or cord-like shadows.Given the lack of effective drugs,treatment focused on symptomatic and respiratory support.Immunoglobulin G was delivered to some critically ill patients according to their conditions.Systemic corticosteroid treatment did not show significant benefits.Notably,early respiratory support facilitated disease recovery and improved prognosis.The risk of death was primarily associated with age,underlying chronic diseases,and median interval from the appearance of initial symptoms to dyspnea.Conclusions:The majority of patients with 2019-nCoV pneumonia present with fever as the first symptom,and most of them still showed typical manifestations of viral pneumonia on chest imaging.Middle-aged and elderly patients with underlying comorbidities are susceptible to respiratory failure and may have a poorer prognosis. | Kui Liu Yuan-Yuan Fang Yan Deng Wei Liu Mei-Fang Wang Jing-Ping Ma Wei Xiao Ying-Nan Wang Min-Hua Zhong Cheng-Hong Li Guang-Cai Li Hui-Guo Liu | 2020 | Chinese Medical Journal2020，，9： | 100 |
| 6 | Liver fibrosis and hepatic stellate cells: Etiology, pathological hallmarks and therapeutic targets显示文摘Liver fibrosis is a reversible wound-healing process aimed at maintaining organ integrity, and presents as the critical pre-stage of liver cirrhosis, which will eventually progress to hepatocellular carcinoma in the absence of liver transplantation. Fibrosis generally results from chronic hepatic injury caused by various factors, mainly viral infection, schistosomiasis, and alcoholism; however, the exact pathological mechanisms are still unknown. Although numerous drugs have been shown to have antifibrotic activity in vitro and in animal models, none of these drugs have been shown to be efficacious in the clinic. Importantly, hepatic stellate cells(HSCs) play a key role in the initiation, progression, and regression of liver fibrosis by secreting fibrogenic factors that encourage portal fibrocytes, fibroblasts, and bone marrow-derived myofibroblasts to produce collagen and thereby propagate fibrosis. These cells are subject to intricate cross-talk with adjacent cells, resulting in scarring and subsequent liver damage. Thus, an understanding of the molecular mechanisms of liver fibrosis and their relationships with HSCs is essential for the discovery of new therapeutic targets. This comprehensive review outlines the role of HSCs in liver fibrosis and details novel strategies to suppress HSC activity, thereby providing new insights into potential treatments for liver fibrosis. | Chong-Yang Zhang Wei-Gang Yuan Pei He Jia-Hui Lei Chun-Xu Wang | 2016 | World Journal of Gastroenterology2016，22，48： | 114 |
| 7 | A review of selective laser melting of aluminum alloys: Processing,microstructure, property and developing trends显示文摘Selective laser melting(SLM) is an attractive rapid prototyping technology for the fabrication of metallic components with complex structure and high performance. Aluminum alloy, one of the most pervasive structural materials, is well known for high specific strength and good corrosion resistance. But the poor laser formability of aluminum alloy restricts its application. There are problems such as limited processable materials, immature process conditions and metallurgical defects on SLM processing aluminum alloys. Some efforts have been made to solve the above problems. This paper discusses the current research status both related to the scientific understanding and technology applications. The paper begins with a brief introduction of basic concepts of aluminum alloys and technology characterization of laser selective melting. In addition, solidification theory of SLM process and formation mechanism of metallurgical defects are discussed. Then, the current research status of microstructure, properties and heat treatment of SLM processing aluminum alloys is systematically reviewed respectively. Lastly, a future outlook is given at the end of this review paper. | Jinliang Zhang Bo Song Qingsong Wei Dave Bourell Yusheng Shi | 2019 | Journal of Materials Science & Technology2019，35，2： | 77 |

| 9 | Treatment of Helicobacter pylori infection in atrophic gastritis显示文摘Helicobacter pylori(Hp) is a major human pathogen causing chronic, progressive gastric mucosal damage and is linked to gastric atrophy and cancer. Hp-positive individuals constitute the major reservoir for transmission of infection. There is no ideal treatment for Hp. Hp infection is not cured by a single antibiotic, and sometimes, a combined treatment with three or more antibiotics is ineffective. Atrophic gastritis(AG) is a chronic disease whose main features are atrophy and/or intestinal metaplasia of the gastric glands, which arise from long-standing Hp infection. AG is reportedly linked to an increased risk for gastric cancer, particularly when extensive intestinal metaplasia is present. Active or past Hp infection may be detected by conventional methods in about two-thirds of AG patients. By immunoblotting of sera against Hp whole-cell protein lysates, a previous exposure to Hp infection is detected in all AG patients. According to guidelines, AG patients with Hp positivity should receive eradication treatment. The goals of treatment are as follows:(1) Cure of infection, resolution of inflammation and normalization of gastric functions;(2) possible reversal of atrophic and metaplastic changes of the gastric mucosa; and(3) prevention of gastric cancer. An ideal antibiotic regimen for Hp should achieve eradication rates of approximately 90%, and complex multidrug regimens are required to reach this goal. Amongst the factors associated with treatment failure are high bacterial load, high gastric acidity, Hp strain, smoking, low compliance, overweight, and increasing antibiotic resistance. AG, when involving the corporal mucosa, is linked to reduced gastric acid secretion. At a non-acidic intra-gastric p H, the efficacy of the common treatment regimens combining proton pump inhibitors with one or more antibiotics may not be the same as that observed in patients with Hp gastritis in an acid-producing stomach. Although the efficacy of these therapeutic regimens has been thoroughly tested in subjects with Hp infection, there is a paucity of evidence in the subgroupof patients with AG. Bismuth-based therapy may be an attractive treatment in the specific setting of AG, and specific studies on the efficacy of bismuth-based therapies are needed in patients with AG. | Edith Lahner Marilia Carabotti Bruno Annibale | 2018 | World Journal of Gastroenterology2018，24，22： | 57 |
| 10 | Diagnosis, treatment, and prevention of 2019 novel coronavirus infection in children: experts' consensus statement显示文摘Since the outbreak of 2019 novel coronavirus infection (2019-nCoV) in Wuhan City,China,by January 30,2020,a total of 9692 confirmed cases and 15,238 suspected cases have been reported around 31 provinces or cities in China.Among the confirmed cases,1527 were severe cases,171 had recovered and been discharged at home,and 213 died.And among these cases,a total of 28 children aged from 1 month to 17 years have been reported in China.For standardizing prevention and management of 2019-nCoV infections in children,we called up an experts' committee to formulate this experts' consensus statement.This statement is based on the Novel Coronavirus Infection Pneumonia Diagnosis and Treatment Standards (the fourth edition) (National Health Committee) and other previous diagnosis and treatment strategies for pediatric virus infections.The present consensus statement summarizes current strategies on diagnosis,treatment,and prevention of 2019-nCoV infection in children. | Kunling Shen Yonghong Yang Tianyou Wang Dongchi Zhao Yi Jiang Runming Jin Yuejie Zheng Baoping Xu Zhengde Xie Likai Lin Yunxiao Shang Xiaoxia Lu Sainan Shu Yan Bai Jikui Deng Min Lu Leping Ye Xuefeng Wang Yongyan Wang Liwei Gao | 2020 | World Journal of Pediatrics2020，16，3： | 56 |
| 11 | The history of interventional therapy for liver cancer in China显示文摘In China interventional therapy of liver cancer started in the 1980s. It is well-known that Professor Lin Gui is the founding father of Interventional radiology. Under the leadership of Lin Gui and other professors, interventional therapy of liver cancer has swiftly progressed in China. Indeed, TAI, TAE, TACE and ablation therapy have witnessed great innovations in hardware facil ities, technical means, and therapeutic philosophy, while incorporating Chinese characteristics. As with the development of combined interventional therapy in China, interventional treatment of liver cancer has gradually started the process of precision and individualization. Actually, multidisciplinary, multimodal, and polymorphic treatments will be the most suitable pattern for liver cancer in the future, among which combination of interventional therapy with targeted, immunological treatments and information technology(IT) tools may bring a revolutionary breakthrough in liver cancer treatment. | Mengxuan Zuo Jinhua Huang | 2018 | Journal of Interventional Medicine2018，1，2： | 59 |
| 12 | Treatment of hemorrhoids: A coloproctologist's view显示文摘Hemorrhoids is recognized as one of the most common medical conditions in general population. It is clinically characterized by painless rectal bleeding during defecation with or without prolapsing anal tissue. Generally,hemorrhoids can be divided into two types: internal hemorrhoid and external hemorrhoid. External hemorrhoid usually requires no specific treatment unless it becomes acutely thrombosed or causes patients discomfort. Meanwhile,low-graded internal hemorrhoids can be effectively treated with medication and nonoperative measures(such as rubber band ligation and injection sclerotherapy). Surgery is indicated for highgraded internal hemorrhoids,or when non-operative approaches have failed,or complications have occurred. Although excisional hemorrhoidectomy remains the mainstay operation for advanced hemorrhoids and complicated hemorrhoids,several minimally invasive operations(including Ligasure hemorrhoidectomy,doppler-guided hemorrhoidal artery ligation and stapled hemorrhoidopexy) have been introduced into surgical practices in order to avoid post-hemorrhiodectomy pain. This article deals with some fundamental knowledge and current treatment of hemorrhoids in a view of a coloproctologist- which includes the management of hemorrhoids in complicated situations such as hemorrhoids in pregnancy,hemorrhoids in immunocompromised patients,hemorrhoids in patients with cirrhosis or portal hypertension,hemorrhoids in patients having antithrombotic agents,and acutely thrombosed or strangulated hemorrhoids. Future perspectives in the treatment of hemorrhoids are also discussed. | Varut Lohsiriwat | 2015 | World Journal of Gastroenterology2015，21，31： | 54 |
| 13 | Resection vs thermal ablation of small hepatocellular carcinoma:What's the first choice?显示文摘Nowadays,hepatocellular carcinoma(HCC) is frequently diagnosed at an early stage,opening good perspectives to radical treatment by means of liver transplantation,surgical resection,or percutaneous ablation.Liver transplantation is considered the best option,but the lack of liver donors represents a major limitation.Therefore,surgical resection,offering a 5-year-survival rate of over 50%,is considered the first-choice treatment for patients with early stage HCC,whereas percutaneous ablation is usually reserved to patients who are not candidate to surgery.However,in the recent years some trials showed that percutaneous radiofrequency ablation(RFA) can be as effective as surgical resection in terms of overall survival and recurrencefree survival rates in patients with small HCC,and a retrospective comparative study reported 1-,3-,and 5-year overall survival rates and recurrence-free survival rates significantly better in patients with central HCC measuring 2 cm or smaller treated with RFA than in those treated with surgical resection.RFA is less expensive,less invasive,with lower complication rate and shorter hospital stay than surgical resection,and on the basis of the results of these studies it should be considered the first option in the treatment of very early HCC.However,RFA is size-dependent,so at present the need to achieve an adequate safety margin around the tumor limits to about 2 cm the diameter of the nodules that can be ablated with long-term outcomes comparable to or better than surgical resection.The main goal of the next technical developments of the thermal ablation systems should be the achievement of larger ablation areas with a single needle insertion.In this regard,the recent improvements in microwave energy delivery systems seem to open interesting perspectives to percutaneous microwave ablation,which could become the ablation technique of choice in the next future. | Paola Tombesi Francesca Di Vece Sergio Sartori | 2013 | World Journal of Radiology2013，5，1： | 50 |
| 14 | A life support-based comprehensive treatment regimen dramatically lowers the in-hospital mortality of patients with fulminant myocarditis: a multiple center study显示文摘Fulminant myocarditis(FM) has unacceptable high mortality. This study aimed to evaluate the therapeutic efficacy of a life support-based comprehensive treatment regimen(LSBCTR), a completely novel treatment regimen, for FM. A total of 169 FM patients recruited from January 2008 to December 2018 were divided into two groups: patients receiving LSBCTR(81 cases),which includes(i) mechanical life support(positive pressure respiration, intra-aortic balloon pump with or without extracorporeal membrane oxygenation),(ii) immunomodulation therapy using sufficient doses of glucocorticoids and immunoglobulins, and(iii) application of neuraminidase inhibitors, and those receiving conventional treatment(88 cases). The endpoints were in-hospital death and heart-transplantation. Of all the population, 44 patients(26.0%) died in hospitals. Inhospital mortality was 3.7%(3/81) for LSBCTR group and 46.6%(41/88) for traditional treatment(P<0.001). Early application of LSBCTR, mechanical life support, neuraminidase inhibitors, and immunomodulation therapy significantly contributed to reduction in in-hospital mortality. This study describes a novel treatment regimen for FM patients that dramatically reduces inhospital mortality. Its generalization and clinical application will efficiently save lives although further optimization is needed.This study offers an insight that virus infection induced inflammatory waterfall results in cardiac injury and cardiogenic shock and is the therapeutic target. | Sheng Li Shengyong Xu Chenze Li Xiao Ran Guanglin Cui Mengying He Kun Miao Chunxia Zhao Jiangtao Yan Rutai Hui Ning Zhou Yan Wang Jiangang Jiang Jing Zhang Daowen Wang | 2019 | Science China(Life Sciences)2019，62，3： | 43 |
| 15 | Diagnosis and treatment recommendations for pediatric respiratory infection caused by the 2019 novel coronavirus显示文摘Since December 2019,an epidemic caused by novel coronavirus (2019-nCoV) infection has occurred unexpectedly in China.As of 8 pm,31 January 2020,more than 20 pediatric cases have been reported in China.Of these cases,ten patients were identified in Zhejiang Province,with an age of onset ranging from 112 days to 17 years.Following the latest National recommendations for diagnosis and treatment of pneumonia caused by 2019-nCo V (the 4th edition) and current status of clinical practice in Zhejiang Province,recommendations for the diagnosis and treatment of respiratory infection caused by 2019-nCoV for children were drafted by the National Clinical Research Center for Child Health,the National Children's Regional Medical Center,Children's Hospital,Zhejiang University School of Medicine to further standardize the protocol for diagnosis and treatment of respiratory infection in children caused by 2019-nCoV. | Zhi-Min Chen Jun-Fen Fu Qiang Shu Ying-Hu Chen Chun-Zhen Hua Fu-Bang Li Ru Lin Lan-Fang Tang Tian-Lin Wang Wei Wang Ying-Shuo Wang Wei-Ze Xu Zi-Hao Yang Sheng Ye Tian-Ming Yuan Chen-Mei Zhang Yuan-Yuan Zhang | 2020 | World Journal of Pediatrics2020，16，3： | 45 |
| 16 | Chinese Stroke Association guidelines for clinical management of cerebrovascular disorders: executive summary and 2019 update of clinical management of ischaemic cerebrovascular diseases显示文摘Aim Stroke is the leading cause of disability and death in China.Ischaemic stroke accounts for about 60%-80%of all strokes.It is of considerable significance to carry out multidimensional management of ischaemic cerebrovascular diseases.This evidence-based guideline aims to provide the latest detailed and comprehensive recommendations on the diagnosis,treatment and secondary prevention of ischaemic cerebrovascular diseases.Methods We had performed comprehensive searches of MEDLINE(via PubMed)(before 30 June 2019),and integrated the relevant information into charts and distributed to the writing group.Writing group members discussed and determined the recommendations through teleconference.We used the level of evidence grading algorithm of Chinese Stroke Association to grade each recommendation.The draft was reviewed by the Guideline Writing Committee of Chinese Stroke Association Stroke and finalised.This guideline is fully updated every 3 years.results This evidence-based guideline is based on the treatment,care and prevention of ischaemic cerebrovascular diseases,which emphasises on pathogenesis evaluation,intravenous thrombolysis,endovascular therapy,antiplatelet therapy,prevention and treatment of complications,and risk factor management.Conclusions This updated guideline presents a framework for the management of ischaemic cerebrovascular diseases.Timely first-aid measures,professional care in the acute stage,and proactive secondary prevention will be helpful to patients. | Liping Liu Weiqi Chen Hongyu Zhou Wanying Duan Shujuan Li Xiaochuan Huo Weihai Xu Li'an Huang Huaguang Zheng Jingyi Liu Hui Liu Yufei Wei Jie Xu Yongjun Wang | 2020 | Stroke & Vascular Neurology2020，5，2： | 42 |
| 17 | Hepatic inflammation and progressive liver fibrosis in chronic liver disease显示文摘Chronic liver inflammation drives hepatic fibrosis,and current immunosuppressive,anti-inflammatory,and anti-viral therapies can weaken this driver.Hepatic fibrosis is reversed,stabilized,or prevented in 57%-79%of patients by conventional treatment regimens,mainly by their anti-inflammatory actions.Responses,however,are commonly incomplete and inconsistently achieved.The fibrotic mechanisms associated with liver inflammation have been clarified,and anti-fibrotic agents promise to improve outcomes as adjunctive therapies.Hepatitis C virus and immune-mediated responses can activate hepatic stellate cells by increasing oxidative stress within hepatocytes.Angiotensin can be synthesized by activated hepatic stellate cells and promote the production of reactive oxygen species.Anti-oxidants(Nacetylcysteine,S-adenosyl-L-methionine,and vitamin E)and angiotensin inhibitors(losartin)have had antifibrotic actions in preliminary human studies,and they may emerge as supplemental therapies.Anti-fibrotic agents presage a new era of supplemental treatment for chronic liver disease. | Albert J Czaja | 2014 | World Journal of Gastroenterology2014，20，10： | 46 |
| 18 | Beyond the stomach: An updated view of Helicobacter pylori pathogenesis, diagnosis, and treatment显示文摘Helicobacter pylori(H. pylori) is an extremely common, yet underappreciated, pathogen that is able to alter host physiology and subvert the host immune response, allowing it to persist for the life of the host. H. pylori is the primary cause of peptic ulcers and gastric cancer. In the United States, the annual cost associated with peptic ulcer disease is estimated to be $6 billion and gastric cancer kills over 700000 people per year globally. The prevalence of H. pylori infection remains high(> 50%) in much of the world, although the infection rates are dropping in some developed nations. The drop in H. pylori prevalence could be a double-edged sword, reducing the incidence of gastric diseases while increasing the risk of allergies and esophageal diseases. The list of diseases potentially caused by H. pylori continues to grow; however, mechanistic explanations of how H. pylori could contribute to extragastric diseases lag far behind clinical studies. A number of host factors and H. pylori virulence factors act in concert to determine which individuals are at the highest risk of disease. These include bacterial cytotoxins and polymorphisms in host genes responsible for directing the immune response. This review discusses the latest advances in H. pylori pathogenesis, diagnosis, and treatment. Up-todate information on correlations between H. pylori and extragastric diseases is also provided. | Traci L Testerman James Morris | 2014 | World Journal of Gastroenterology2014，20，36： | 47 |
| 19 | Treatment options for alcoholic and non-alcoholic fatty liver disease: A review显示文摘Alcoholic liver disease(ALD)and non-alcoholic fatty liver disease(NAFLD)are serious health problems worldwide.These two diseases have similar pathological spectra,ranging from simple steatosis to hepatitis to cirrhosis and hepatocellular carcinoma.Although most people with excessive alcohol or calorie intake display abnormal fat accumulation in the liver(simple steatosis),a small percentage develops progressive liver disease.Despite extensive research on understanding the pathophysiology of both these diseases there are still no targeted therapies available.The treatment for ALD remains as it was 50 years ago:abstinence,nutritional support and corticosteroids(or pentoxifylline as an alternative if steroids are contraindicated).As for NAFLD,the treatment modality is mainly directed toward weight loss and co-morbidity management.Therefore,new pathophysiology directed therapies are urgently needed.However,the involvement of several inter-related pathways in the pathogenesis of these diseases suggests that a single therapeutic agent is unlikely to be an effective treatment strategy.Hence,a combination therapy towards multiple targets would eventually be required.In this review,we delineate the treatment options in ALD and NAFLD,including various new targeted therapies that are currently under investigation.We hope that soon we will be having an effective multi-therapeutic regimen for each disease. | Sukhpreet Singh Natalia A Osna Kusum K Kharbanda | 2017 | World Journal of Gastroenterology2017，23，36： | 45 |
| 20 | Minimally invasive treatment of cholecysto-choledocal lithiasis:The point of view of the surgical endoscopist显示文摘The rate of choledocholithiasis in patients with symptomatic cholelithiasis is estimated to be approximately 10%-33%,depending on the patient's age.Development of Endoscopic Retrograde Cholangiopancreatography and Laparoscopic Surgery and improvement of diagnostic procedures have influenced new approaches to the management of common bile duct stones in association with gallstones.At present available minimally-invasive treatments of cholecysto-choledocal lithiasis include:single-stage laparoscopic treatment,perioperative endoscopic treatment and endoscopic treatment alone.Published data evidence that,associated endoscopic-laparoscopic approach necessitates increased number of procedures per patient while single-stage laparoscopic treatment is associated with a shorter hospital stay.However,current data does not suggest clear superiority of any one approach with regard to success,mortality,morbidity and cost-effectiveness.Considering the variety of therapeutic options available for management,a critical appraisal and decision-making is required.endoscopic retrograde cholangiopancreatography/EST should be adopted on a selective basis,i.e.,in patients with acute obstructive suppurative cholangitis,severe biliary pancreatitis,ampullary stone impaction or severe comorbidity.In a setting where all facilities are available,decision in the selection of the therapeutic option depends on the patients,the number and size of choledocholithiasis stones,the anatomy of the cystic duct and common bile duct,the surgical history of patients and local expertise. | Giovanni D De Palma | 2013 | World Journal of Gastrointestinal Surgery2013，5，6： | 36 |
