| 1 | Cirrhosis and its complications:Evidence based treatment显示文摘Cirrhosis results from progressive fibrosis and is the final outcome of all chronic liver disease.It is among the ten leading causes of death in United States.Cirrhosis can result in portal hypertension and/or hepatic dysfunction.Both of these either alone or in combination can lead to many complications,including ascites,varices,hepatic encephalopathy,hepatocellular carcinoma,hepatopulmonary syndrome,and coagulation disorders.Cirrhosis and its complications not only impair quality of life but also decrease survival.Managing patients with cirrhosis can be a challenge and requires an organized and systematic approach.Increasing physicians’knowledge about prevention and treatment of these potential complications is important to improve patient outcomes.A literature search of the published data was performed to provide a comprehensive review regarding the management of cirrhosis and its complications. | Salman Nusrat Muhammad S Khan Javid Fazili Mohammad F Madhoun | 2014 | World Journal of Gastroenterology2014，20，18： | 14 |
| 2 | 轻量型网片可以提高腹腔镜全腹膜外腹股沟疝修补术后的功能结局显示文摘前瞻性研究旨在比较腹腔镜全腹膜外腹股沟疝修补术(TEP)中,采用新型轻量型网片和传统重量型网片的差异,所有手术均在同一疝中心完成。方法自2004年11月到2005年7月,共有250例病人接受了腹腔镜TEP,采用轻量型(Ultrapro,30g/m)2或重量型网片(Prolene,100g/m2)。通过病历资料回顾及电话问卷调查获得随访数据。术后早期及远期均对病人进行随访,以评估术后结局的变化。结果 250例中有188例(75%)获得随访。在术后平均4个月及15个月进行的随访中发现,轻量型网片组和重量型网片组在疼痛或不适感的发生率及程度上没有差别。轻量型网片组在术后早期及远期对体力活动的影响显著小于重量型网片组,尤其是举重(9%vs.21%,平均随访4个月,Mann-WhitneyU,P=0.024)、行走(1%vs.11%,平均随访5个月,Mann-WhitneyU,P=0.006)及剧烈运动(7%vs.19%,平均随访15个月,Mann-Whitney-U,P=0.012)。腹股沟区的网片感或不适感两组差异无统计学意义。结论采用轻量型网片行腹腔镜TEP可以改善术后早期及远期的功能结局。轻量型网片可以显著减少对所有体力活动的影响。两者的疼痛都较轻微,表明腹腔镜手术的优势。 | Khan LR Liong S de Beaux AC Kumar S Nixon SJ | 2010 | 中国实用外科杂志2010，30，7： | 14 |
| 3 | Retrospective study on mixed neuroendocrine non-neuroendocrine neoplasms from five European centres显示文摘BACKGROUND Mixed neuroendocrine non-neuroendocrine neoplasm(MiNEN)is a rare diagnosis,mainly encountered in the gastro-entero-pancreatic tract.There is limited knowledge of its epidemiology,prognosis and biology,and the best management for affected patients is still to be defined.AIM To investigate clinical-pathological characteristics,treatment modalities and survival outcomes of a retrospective cohort of patients with a diagnosis of MiNEN.METHODS Consecutive patients with a histologically proven diagnosis of MiNEN were identified at 5 European centres.Patient data were retrospectively collected from medical records.Pathological samples were reviewed to ascertain compliance with the 2017 World Health Organisation definition of MiNEN.Tumour responses to systemic treatment were assessed according to the Response Evaluation Criteria in Solid Tumours 1.1.Kaplan-Meier analysis was applied to estimate survival outcomes.Associations between clinical-pathological characteristics and survival outcomes were explored using Log-rank test for equality of survivors functions(univariate)and Cox-regression analysis(multivariable).RESULTS Sixty-nine consecutive patients identified;Median age at diagnosis:64 years.Males:63.8%.Localised disease(curable):53.6%.Commonest sites of origin:colon-rectum(43.5%)and oesophagus/oesophagogastric junction(15.9%).The neuroendocrine component was;predominant in 58.6%,poorly differentiated in 86.3%,and large cell in 81.25%,of cases analysed.Most distant metastases analysed(73.4%)were occupied only by a poorly differentiated neuroendocrine component.Ninety-four percent of patients with localised disease underwent curative surgery;53%also received perioperative treatment,most often in line with protocols for adenocarcinomas from the same sites of origin.Chemotherapy was offered to most patients(68.1%)with advanced disease,and followed protocols for pure neuroendocrine carcinomas or adenocarcinomas in equal proportion.In localised cases,median recurrence free survival(RFS);14.0 months(95%CI:9.2-24.4),and median overall survival(OS):28.6 months(95%CI:18.3-41.1).On univariate analysis,receipt of perioperative treatment(vs surgery alone)did not improve RFS(P=0.375),or OS(P=0.240).In advanced cases,median progression free survival(PFS);5.6 months(95%CI:4.4-7.4),and median OS;9.0 months(95%CI:5.2-13.4).On univariate analysis,receipt of palliative active treatment(vs best supportive care)prolonged PFS and OS(both,P<0.001).CONCLUSION MiNEN is most commonly driven by a poorly differentiated neuroendocrine component,and has poor prognosis.Advances in its biological understanding are needed to identify effective treatments and improve patient outcomes. | Melissa Frizziero Xin Wang Bipasha Chakrabarty Alexa Childs Tu V Luong Thomas Walter Mohid S Khan Meleri Morgan Adam Christian Mona Elshafie Tahir Shah Annamaria Minicozzi Wasat Mansoor Tim Meyer Angela Lamarca Richard A Hubner Juan W Valle Mairéad G McNamara | 2019 | World Journal of Gastroenterology2019，25，39： | 13 |
| 4 | Abdominal applications of diffusion-weighted magnetic resonance imaging: Where do we stand?显示文摘Diffusion-weighted imaging (DWI) is one of the magnetic resonance imaging (MRI) sequences providing qualitative as well as quantitative information at a cellular level. It has been widely used for various applications in the central nervous system. Over the past decade, various extracranial applications of DWI have been increasingly explored, as it may detect changes even before signal alterations or morphological abnormalities become apparent on other pulse sequences. Initial results from abdominal MRI applications are promising, particularly in oncological settings and for the detection of abscesses. The purpose of this article is to describe the clinically relevant basic concepts of DWI, techniques to perform abdominal DWI, its analysis and applications in abdominal visceral MR imaging, in addition to a brief overview of whole body DWI MRI. | Ajaykumar C Morani Khaled M Elsayes Peter S Liu William J Weadock Janio Szklaruk Jonathan Russell Dillman Asra Khan Thomas L Chenevert Hero K Hussain | 2013 | World Journal of Radiology2013，5，3： | 12 |
| 5 | Immune response to an indigenously developed r-Hepatitis B vaccine in mixed population: Study of an accelerated vaccination schedule显示文摘AIM: To establish the safety and efficacy of an indigenously developed r-hepatitis B vaccine using an accelerated schedule and to highlight the social awareness and commitment in preventing the spreading of hepatitis B virus infection.METHODS: The study was a multicentric, double blind,randomized (3:1) study using three doses of vaccine immunization schedule (20 μg for those above 10 years old and 10 μg for those below 10 years old) on d 0, 30and 60. One hundred and sixty-six subjects were enrolled(87 males and 76 females aged 5-35 years). The main outcome measure was assessment of immunogenicity and safety.RESULTS: A 100% seroconversion response was observed on the 30th d after the 1st injection in both the experimental groups. The sero-protection data reported a 41.2-65.6% response on the 30th d after the 1st injection and reached 100% on the 60th d. Descriptive statical analysis showed a geometric mean titer value of 13.77 mIU/mL in the test (BEVAC) group and 10.95 mIU/mL in the commercial control (ENGERIX-B) group on the 30th d after the 1st injection. The response on the 60th d showed a geometric mean titre value (GMT) of 519.84 mIU/mL in the BEVAC group and 475.46 mIU/mL in the ENGERIX-B group. On the 90th d, the antibody titer response was observed to be 2627.58 mIU/mL in the BEVAC group and 2272.72 mIU/mL in the ENGERIX-B group. Two subjects in each group experienced pains at injection site after the first vaccination. A total of six subjects in both groups experienced a solicited adverse reaction, which included pains, swelling and redness at the injection site, three subjects in the group-B had a pain at the injection site after the third dose. No other serious adverse events occurred and no dose-related local or general symptoms were observed during the study.CONCLUSION: The vaccine is safe, efficacious and immunogenic in comparison with the well documented ENGERIX-B. | A Chowdhury A Santra CM Habibullah AA Khan J Karunakaramaiah TSA Kishore AVR Raju S Lahiri | 2005 | World Journal of Gastroenterology2005，11，7： | 12 |
| 6 | 动物研究系统评价的方法学质量调查显示文摘目的系统评价可作为将基础生命科学研究从实验室转化到人体研究和健康保健措施的工具。对动物研究的系统评价是否系统且不存在偏倚,目前尚不知。方法我们检索了MED LINE、EMBASE、已知系统评价的参考文献(1996~2004)并联系相关专家,至少检索一个对公众开放的数据库全面收集基础科学文献的引文,均未设定语言限制。我们从中纳入那些在动物身上测量实验室参数或在活体动物身上给予治疗以评价疗效研究的系统评价,并将其与在实验室中研究人体或动物组织、细胞系统或器官标本以进一步了解疾病机理体外研究的系统评价进行比较。结果动物研究的系统评价通常缺少如定义供检验的假设(9/30,30%);文献检索不设语言限制(8/30,26.6%);评价发表偏倚(5/30,16.6%)、研究的真实性(15/30,50%)和异质性(10/30,33.3%);及使用Meta分析用于定量合成(12/30,40%)等方法学特征。与体外研究的系统评价相比,动物研究的系统评价更多地限定了研究问题(96.6%vs.80%,P=0.04)、综合检索了多个数据库(60%vs.26.6%,P=0.01)、评价了研究质量(50%vs.20%,P=0.01)及探讨了研究异质性(33.3%vs.2.2%,P=0.001),因此更少出现偏倚。结论在各类系统评价中,方法学质量问题的出现频率似乎存在一定的梯度:虽然与人体临床试验的系统评价相比,整体动物研究的系统评价质量明显较差,但其仍优于体外研究的系统评价。在系统评价动物研究时,有必要更严格。 | Luciano E Mignini Khalid S Khan 刁骧(译) 李幼平(审校) | 2006 | 中国循证医学杂志2006，6，10： | 8 |
| 7 | Imaging of liver cancer显示文摘Improvements in imaging technology allow exploitation of the dual blood supply of the liver to aid in the identif ication and characterisation of both malignant and benign liver lesions. Imaging techniques available include contrast enhanced ultrasound, computed tomography and magnetic resonance imaging. This review discusses the application of several imaging techniques in the diagnosis and staging of both hepatocellular carcinoma and cholangiocarcinoma and outlines certain characteristics of benign liver lesions. The advantages of each imaging technique are highlighted, while underscoring the potential pitfalls and limitations of each imaging modality. | Ben Ariff Claire R Lloyd Sameer Khan Mohamed Shariff Andrew V Thillainayagam Devinder S Bansi Shahid A Khan Simon D Taylor-Robinson Adrian KP Lim | 2009 | World Journal of Gastroenterology2009，15，11： | 4 |
| 8 | Current surgical treatment strategies for hepatocellular carcinoma in North America显示文摘Hepatocellular carcinoma(HCC) is an aggressive tumor that often occurs in the setting of chronic liver disease.Many patients do not initially manifest any symptoms of HCC and present late when cure with surgical resection or transplantation is no longer possible.For this reason,patients at high risk for developing HCC are subjected to frequent screening processes.The surgical management of HCC is complex and requires an inter-disciplinary approach.Hepatic resection is the treatment of choice for HCC in patients without cirrhosis and is indicated in some patients with early cirrhosis(Child-Pugh A).Liver transplantation has emerged in the past decade as the standard of care for patients with cirrhosis and HCC meeting Milan criteria and in select patients with HCC beyond Milan criteria.Loco-regional therapy with transarterial chemoembolization,transarterial embolization,radiofrequency ablation and other similar local treatments can be used as neo-adjuvant therapy to downstage HCC to within Milan criteria or as a bridge to transplantation in patients on transplant wait list. | Adeel S Khan Kathryn J Fowler William C Chapman | 2014 | World Journal of Gastroenterology2014，20，41： | 3 |
| 9 | Single vs dual(en bloc) kidney transplants from donors ≤ 5 years of age: A single center experience显示文摘AIM: To compare outcomes between single and dual en bloc(EB) kidney transplants(KT) from small pediatric donors. METHODS: Monocentric nonprospective review of KTs from pediatric donors ≤ 5 years of age. Dual EB KT was defined as keeping both donor kidneys attached tothe inferior vena cava and aorta, which were then used as venous and arterial conduits for the subsequent transplant into a single recipient. Donor age was less useful than either donor weight or kidney size in decision-making for kidney utilization as kidneys from donors < 8 kg or kidneys < 6 cm in length were not transplanted. Post-transplant management strategies were standardized in all patients.RESULTS: From 2002-2015, 59 KTs were performed including 34 dual EB and 25 single KTs. Mean age of donors(17 mo vs 38 mo, P < 0.001), mean weight(11.0 kg vs 17.4 kg, P = 0.046) and male donors(50% vs 84%, P = 0.01) were lower in the dual EB compared to the single KT group, respectively. Mean cold ischemia time(21 h), kidney donor profile index(KDPI; 73% vs 62%) and levels of serum creatinine(SCr, 0.37 mg/d L vs 0.49 mg/d L, all P = NS) were comparable in the dual EB and single KT groups, respectively. Actuarial graft and patient survival rates at 5-years follow-up were comparable. There was one case of thrombosis resulting in graft loss in each group. Delayed graft function incidence(12% dual EB vs 20% single KT, P = NS) was slightly lower in dual EB KT recipients. Initial duration of hospital stay(mean 5.4 d vs 5.6 d) and the one-year incidences of acute rejection(6% vs 16%), operative complications(3% vs 4%), and major infection were comparable in the dual EB and single KT groups, respectively(all P = NS). Mean 12 mo SCr and abbreviated MDRD levels were 1.17 mg/d L vs 1.35 mg/d L and 72.5 m L/min per 1.73 m^2 vs 60.5 m L/min per 1.73 m^2(both P = NS) in the dual EB and single KT groups, respectively. CONCLUSION: By transplanting kidneys from young pediatric donors into adult recipients, one can effectively expand the limited donor pool and achieve excellent medium-term outcomes. | Yousef Al-Shraideh Umar Farooq Hany El-Hennawy Alan C Farney Amudha Palanisamy Jeffrey Rogers Giuseppe Orlando Muhammad Khan Amber Reeves-Daniel William Doares Scott Kaczmorski Michael D Gautreaux Samy S Iskandar Gloria Hairston Elizabeth Brim Margaret Mangus Robert J Stratta | 2016 | World Journal of Transplantation2016，6，1： | 3 |

| 11 | Neuromuscular electrical stimulation and testosterone did not influence heterotopic ossification size after spinal cor injury: A case series显示文摘Neuromuscular electrical stimulation(NMES) and testosterone replacement therapy(TRT) are effective rehabilitation strategies to attenuate muscle atrophy and evoke hypertrophy in persons with spinal cord injury(SCI). However both interventions might increase heterotopic ossification(HO) size in SCI patients. We present the results of two men with chronic traumatic motor complete SCI who also had pre-existing HO and participated in a study investigating the effects of TRT or TRT plus NMES resistance training(RT) on body composition. The 49-year-old male, Subject A, has unilateral HO in his right thigh. The 31-year-old male, Subject B, has bilateral HO in both thighs. Both participants wore transdermal testosterone patches(4-6 mg/d) daily for 16 wk. Subject A also underwent progressive NMES-RT twice weekly for 16 wk. Magnetic resonance imaging scans were acquired prior to and post intervention. Cross-sectional areas(CSA) of thewhole thigh and knee extensor skeletal muscles, femoral bone, and HO were measured. In Subject A(NMES-RT + TRT), the whole thigh skeletal muscle CSA increased by 10%, the knee extensor CSA increased by 17%, and the HO + femoral bone CSA did not change. In Subject B(TRT), the whole thigh skeletal muscle CSA increased by 13% in the right thigh and 6% in the left thigh. The knee extensor CSA increased by 7% in the right thigh and did not change in the left thigh. The femoral bone and HO CSAs in both thighs did not change. Both the TRT and NMES-RT + TRT protocols evoked muscle hypertrophy without stimulating the growth of preexisting HO. | Pamela D Moore Ashraf S Gorgey Rodney C Wade Refka E Khalil Timothy D Lavis Rehan Khan Robert A Adler | 2016 | World Journal of Clinical Cases2016，4，7： | 3 |

| 13 | Analysing the outcome of surgery for chronic Achilles tendinopathy over the last 50 years显示文摘AIM: To determine an association between when the study was performed, the robustness of the study and the outcomes for insertional and non-insertional Achilles tendinopathy surgery. METHODS: We performed a systematic review in accordance with the PRISMA guidelines to assess the methodology of studies investigating the outcome of surgery in chronic Achilles tendinopathy over the last 50 years to identify any trends that would account for the variable results. The Coleman Methodology Scores were correlated with the reported percentage success rates and with the publication year to determine any trends using Pearson's correlation. RESULTS: We identified 62 studies published between 1964 and 2014 reporting on a total of 2923 surgically treated Achilles tendinopathies. The average followup time was 40 mo(range 5-204 mo), and the mean reported success rate was 83.5%(range 36%-100%). The Coleman Methodology Scores were highly reproducible(r = 0.99, P < 0.01), with a mean of 40.1(SD 18.9, range 2-79). We found a negative correlation between reported success rate and overall methodology scores(r =-0.40, P < 0.001), and a positive correlation between year of publication and overall methodology scores(r = 0.46, P < 0.001). CONCLUSION: We conclude that although the success rate of surgery for chronic Acilles tendinopathy described in the literature has fallen over the last 50 years, this is probably due to a more rigorous methodology of the studies. | Wasim S Khan Seema Malvankar Jagmeet S Bhamra Ioannis Pengas | 2015 | World Journal of Orthopedics2015，6，6： | 3 |

| 15 | Physiological and biochemical appraisal for mulching and partial rhizosphere drying of cotton显示文摘Water is the main factor for the healthy life of plant.One of the main negative effects of climate change is the increasing scarcity of water that is lethal for plant.Globally,for water deficit regions(arid and semi-arid),drought is the main factor responsible for low production of agriculture,especially for cotton.Great efforts have been and are being made to find alternatives to water saving practices.This study aimed to examine the effects of partial rhizosphere drying(PRD,half of the root system irrigated at one event,and the other half irrigated in the next event,and so on)with and/or without various mulching treatments on physiological and biochemical traits of cotton.To explore this objective,we laid out experiments in completely randomized design with factorial arrangement in the Islamia University of Bahawalpur,Pakistan in 2016.Two factors included were four mulching treatments(M0,no mulching;M1,black plastic mulching;M2,wheat straw mulching;and M3,cotton sticks mulching)and two irrigation levels(I0,control(full irrigation);and I1,PRD).Fisher's analysis of variance among means of treatments was compared using least significant difference test at 5% probability level.Results revealed that the maximum plant height,leaf area,leaf gas exchange(photosynthetic rate and stomata conductance),chlorophyll,proline and total sugar contents,and enzyme activities were higher under M2 than under other three mulching treatments.As for irrigation levels,higher values of plant height,photosynthesis and water related parameters(leaf water potential,leaf osmotic potential,leaf turgor potential,etc.)were recorded.Contents of total sugar and proline and activities of antioxidant enzymes were significantly higher in PRD-treated plants than in control plants.It was concluded that combined application of PRD and mulching was more effective than the rest of the treatments used in the experiment.Similar study can be conducted in the field by applying irrigation water in alternate rows in semi-arid regions. | Rashid IQBAL Muhammad A S RAZA Muhammad F SALEEM Imran H KHAN Salman AHMAD Muhammad S ZAHEER Muhammad U ASLAM Imran HAIDER | 2019 | Journal of Arid Land2019，11，5： | 2 |

| 18 | Improved dielectric and electro-optical parameters of nematic liquid crystal doped with magnetic nanoparticles显示文摘This study investigates the effect of magnetic nanoparticles(NPs) on the weakly polar nematic liquid crystal(NLC).Different parameters of dielectric data were measured for both the homeotropic and planar aligned samples as a function of frequency and temperature and the substantial changes have been noticed for the doped systems. Dielectric permittivity has been increased after the dispersion of magnetic NPs in the pure NLC. Dielectric anisotropy has also been influenced by incorporating the magnetic NPs with the NLC molecules. These results were attributed to the dipole–dipole interaction between the magnetic nanoparticles and nematic liquid crystal molecules. Electro-optical study indicated the faster rise time and fall time of the doped systems as compare to pure NLC. Threshold voltage has been calculated and found to be decreased for the doped systems. Moreover, we have also calculated the rotational viscosity and the splay elastic constant for pure and the doped systems. Both the rotational viscosity and splay elastic constant of the doped systems are found to be considerably lower than those of pure NLC. Change in these properties has been explained on the basis of molecular disturbances created by the interaction between the magnetic nanoparticle and LC director. This study reveals that the inclusion of magnetic NPs in weakly polar NLC can be useful to enhance the basic properties of the weakly polar NLC and make it a promising material for many display applications. | Geeta Yadav Govind Pathak Kaushlendra Agrahari Mahendra Kumar Mohd Sajid Khan V S Chandel Rajiv Manohar | 2019 | Chinese Physics B2019，28，3： | 2 |
