| 1 | Evolution of transanal total mesorectal excision for rectal cancer:From top to bottom显示文摘The gold standard for curative treatment of locally advanced rectal cancer involves radical resection with a total mesorectal excision(TME). TME is the most effective treatment strategy to reduce local recurrence and improve survival outcomes regardless of the surgical platform used. However, there are associated morbidities, functional consequences, and quality of life(QoL) issues associated with TME; these risks must be considered during the modern-day multidisciplinary treatment for rectal cancer. This has led to the development of new surgical techniques to improve patient, oncologic, and QoL outcomes. In this work, we review the evolution of TME to the transanal total mesorectal excision(TaTME) through more traditional minimally invasive platforms. The review the development, safety and feasibility, proposed benefits and risks of the procedure, implementation and education models, and future direction for research and implementation of the TaTME in colorectal surgery. While satisfactory short-term results have been reported, the procedure is in its infancy, and long term outcomes and definitive results from controlled trials are pending.As evidence for safety and feasibility accumulates,structured training programs to standardize teaching,training, and safe expansion will aid the safe spread of the TaTME. | Sameh Hany Emile F Borja de Lacy Deborah Susan Keller Beatriz Martin-Perez Sadir Alrawi Antonio M Lacy Manish Chand | 2018 | World Journal of Gastrointestinal Surgery2018，10，3： | 18 |

| 4 | Monitoring the impact of climate change and human activities on grassland vegetation dynamics in the northeastern Qinghai-Tibet Plateau of China during 2000–2015显示文摘Climate change and human activities can influence vegetation net primary productivity(NPP), a key component of natural ecosystems. The Qinghai-Tibet Plateau of China, in spite of its significant natural and cultural values, is one of the most susceptible regions to climate change and human disturbances in the world. To assess the impact of climate change and human activities on vegetation dynamics in the grassland ecosystems of the northeastern Qinghai-Tibet Plateau, we applied a time-series trend analysis to normalized difference vegetation index(NDVI) datasets from 2000 to 2015 and compared these spatiotemporal variations with trends in climatic variables over the same time period. The constrained ordination approach(redundancy analysis) was used to determine which climatic variables or human-related factors mostly influenced the variation of NDVI. Furthermore, in order to determine whether current conservation measures and programs are effective in ecological protection and reconstruction, we divided the northeastern Qinghai-Tibet Plateau into two parts: the Three-River Headwater conservation area(TRH zone) in the south and the non-conservation area(NTRH zone) in the north. The results indicated an overall(73.32%) increasing trend of vegetation NPP in grasslands throughout the study area. During the period 2000–2015, NDVI in the TRH and NTRH zones increased at the rates of 0.0015/a and 0.0020/a, respectively. Specifically, precipitation accounted for 9.2% of the total variation in NDVI, while temperature accounted for 13.4%. In addition, variation in vegetation NPP of grasslands responded not only to long-and short-term changes in climate, as conceptualized in non-equilibrium theory, but also to the impact of human activities and their associated perturbations. The redundancy analysis successfully separated the relative contributions of climate change and human activities, of which village population and agricultural gross domestic product were the two most important contributors to the NDVI changes, explaining 17.8% and 17.1% of the total variation of NDVI(with the total contribution >30.0%), respectively. The total contribution percentages of climate change and human activities to the NDVI variation were 27.5% and 34.9%, respectively, in the northeastern Qinghai-Tibet Plateau. Finally, our study shows that the grassland restoration in the study area was enhanced by protection measures and programs in the TRH zone, which explained 7.6% of the total variation in NDVI. | XIONG Qinli XIAO Yang Marwa Waseem A HALMY Mohammed A DAKHIL LIANG Pinghan LIU Chenggang ZHANG Lin Bikram PANDEY PAN Kaiwen Sameh B EL KAFRAWAY CHEN Jun | 2019 | Journal of Arid Land2019，11，5： | 10 |

| 6 | 种植方式和灌溉定额对碱化盐土及紫穗槐生长的影响显示文摘针对甘肃白银碱化盐土表层土壤盐分高、植物生长困难的生产问题,在统一施用脱硫石膏18t/hm^2的基础上,通过2 a田间试验,在起垄沟植和未起垄种植2种种植方式下设置3个灌溉定额:8 250、9 750和11 250 m^3/hm^2,研究不同种植方式及灌溉定额对土壤pH值、碱化度、含盐量及紫穗槐生长的影响。试验结果表明:1)各处理均显著降低了土壤pH值、碱化度和含盐量;起垄沟植方式下垄沟内可汇集灌溉水和降水,提高土壤含水率;在0~40 cm土层起垄处理的土壤盐分比未起垄处理低15.7%,起垄沟植处理可以形成'高水低盐'的水盐环境,从而使紫穗槐的成活率、株高、冠幅均高于未起垄处理;2)2种种植方式下,随灌水量增加脱盐效果越显著,紫穗槐的成活率、株高、冠幅指标随灌水量增加而增加;灌溉定额为9 750和11 250 m^3/hm^2时,紫穗槐生长指标无显著差异。考虑到研究区地处干旱区,水资源有限,灌水量过多不仅浪费水资源还会增加发生次生盐渍化的风险,因此,施用脱硫石膏并起垄沟植适宜于甘肃白银碱化盐土紫穗槐种植,且适宜灌溉定额为9 750 m^3/hm^2。 | 王旭 樊丽琴 李磊 孙兆军 Sameh El-Sway | 2020 | 农业工程学报2020，36，5： | 7 |
| 7 | Do inhaled corticosteroids increase the risk of Pneumocystis pneumonia in people with lung cancer?显示文摘Pneumocystis pneumonia(PCP) is a life-threatening infection in immunocompromised patients. It is relatively uncommon in patients with lung cancer. We report a case of PCP in a 59-year-old man with a past medical history of chronic obstructive pulmonary disease treated with formoterol and a moderate daily dose of inhaled budesonide. He had also advanced stage non-small lung cancer treated with concurrent chemo-radiation with a cisplatin-etoposide containing regimen. The diagnosis of PCP was suspected based on the context of rapidly increasing dyspnea, lymphopenia and the imaging findings. Polymerase chain reaction testing on an induced sputum specimen was positive for Pneumocystis jirovecii. The patient was treated with oral trimethoprim-sulfamethoxazole and systemic corticotherapy and had showed clinical and radiological improvement. Six months after the PCP diagnosis, he developed a malignant pleural effusion and expired on hospice care. Through this case, we remind the importance of screening for PCP in lung cancer patients under chemotherapeutic regimens and with increasing dyspnea. In addition, we alert to the fact that long-term inhaled corticosteroids may be a risk factor for PCP in patients with lung cancer. Despite intensive treatment, the mortality of PCP remains high, hence the importance of chemoprophylaxis should be considered. | Sameh Msaad Ilhem Yangui Najla Bahloul Narjes Abid Makram Koubaa Yosr Hentati Mounir Ben Jemaa Samy Kammoun | 2015 | World Journal of Clinical Cases2015，3，9： | 5 |
| 8 | Experimental and numerical modelling of sedimentation in a rectangular shallow basin显示文摘Numerical simulation of flows in shallow reservoirs has to be checked for its consistency in predicting real flow conditions and sedimentation patterns. Typical flow patterns may exhibit flow separation at the inlet, accompanied by several recirculation and stagnation areas all over the reservoir surface. The aim of the present research project is to study the influence of the geometry of a reservoir on sediment transport and deposition numerically and experimentally, focusing on a prototype reservoir depth between 5 and 15 m as well as suspended sediment transport. A series of numerical simulations is presented and compared with scaled laboratory experiments, with the objective of testing the sensitivity to different flow and sediment parameters and different turbulence closure schemes. Different scenarios are analyzed and a detailed comparison of preliminary laboratory tests and some selected simulations are presented. The laboratory experiments show that suspended sediment transport and deposition are determined by the initial flow pattern and by the upstream and downstream boundary conditions. In the experiments, deposition in the rectangular basin systematically developed along the left bank, although inflow and outflow were positioned symmetrically along the centre of the basin. Three major horizontal eddies developed influencing the sediment deposition pattern. Although asymmetric flow patterns are privileged, a symmetric pattern can appear from time to time. This particular behaviour could also be reproduced by a two-dimensional depth-averaged flow and sediment transport model (CCHE2D). The paper presents numerical simulations using different turbulence closure schemes (k-ε and eddy viscosity models). In spite of the symmetric setup, these generally produced an asymmetric flow pattern that can easily switch sides depending on the assumptions made for the initial and boundary conditions. When using the laboratory experiment as a reference, the most reliable numerical results have been obtained with a parabolic depth-averaged eddy viscosity model. This model appeared to be the only one that was able to reproduce the strongly asymmetric flow behaviour observed during the experiments. | Sameh A. KANTOUSH Erik BOLLAERT Anton J.

| 9 | Stem cells in gastrointestinal cancers: The road less travelled显示文摘Cancer stem cells(CSC) are thought to be malignant cells that have the capacity to initiate and maintain tumor growth and survival. Studies have described CSC in various gastrointestinal neoplasms such as colon, pancreas and liver and gastroesophageal tumors. The mechanism by which CSC develop remains unclear. Several studies have explored the role of dysregulation of the Wnt/β-catenin, transformation growth factor-beta and hedhog pathways in generation of CSC. In this review, we discuss the various molecular abnormalities that may be related to formation of CSC in gastrointestinal malignancies, strategies to identify CSC and therapeutic strategies that are based on these concepts. Identification and targeting CSC is an intriguing area and may provide a new therapeutic option for patients with cancer including gastrointestinal malignancies. Although great progress has been made, many issues need to be addressed. Precise targeting of CSC will require precise isolation and characterization of those cells. This field is also evolving but further research is needed to identify markers that are specific for CSC.Although the application of this field has not entered the clinic yet, there continues to be significant optimism about its potential utility in overcoming cancer resistance and curing patients with cancer. | Sameh Mikhail Amer Zeidan | 2014 | World Journal of Stem Cells2014，6，5： | 5 |

| 11 | Liver stiffness as a predictor of hepatocellular carcinoma behavior in patients with hepatitis C related liver cirrhosis显示文摘Background: Risk strati cation and prognostication of hepatocellular carcinoma (HCC) help to improve patient outcome. Herein we investigated the role of liver stiffness measurement (LSM) in the prediction of HCC behavior. Methods: Totally 121 na ve patients with HCC were included. HCC radiological evaluation and staging were done. LSM was measured using virtual touch quanti cation. Patients were divided into early to intermediate HCC (BCLC-0, A and B) and late HCC (BCLCC and D). HCC was treated according to the BCLC stage. HCC recurrence-free interval was estimated. Results: The mean LSM inside the tumor was signi cantly lower than the peri-tumoral area and the cirrhotic non-cancerous liver parts (P<0.001). In late HCCs stage, the mean LSM inside the tumor and in the peri-tumoral tissue was lower than the corresponding values in the early to intermediate HCCs stage (P<0.001). LSM inside the tumor and in the peri-tumoral tissue negatively correlated with serum AFP, tumor vascular invasion, and stage (P<0.05). The recurrence-free interval was directly correlated to LSM inside the tumor and inversely to LSM in cirrhotic non tumorous liver part. Kaplan-Meier analysis showed that the recurrence-free interval was signi cantly longer in patients with LSM inside the tumor of ≥1.25m/s compared to those with LSM inside the tumor of<1.25m/s. Conclusions: LSM can serve as a potential non-invasive predictor for HCC clinical behavior and the recurrence-free interval following loco-regional treatments. | Sameh A Lashen Mohamed M Elshafei Fahmy H Hablass Eman A Alsayed Asmaa A Hassan | 2020 | Hepatobiliary & Pancreatic Diseases International2020，19，1： | 4 |

| 19 | Efficacy and safety of botulinum toxin in treatment of anismus: A systematic review显示文摘AIM: To evaluate the efficacy and safety of botulinum toxin type A(BTX-A) in the management of patients with anismus. METHODS: An organized search of published literature was conducted using electronic databases including: Pub Med/MEDLINE, and Cochrane Central Register of Control ed Trials, also an internet-based search using 'Google Scholar' service was conducted. Both comparative and observational studies were included. We excluded irrelevant articles, editorials, case reports, reviews, and meta-analyses. The studies that followed the patients less than 6 mo were excluded. Variables collected were demographic data of the patients, technique of BTX-A injection and number of sessions, short-term and longterm clinical improvement, post-injection changes in electromyography(EMG), defecography, manometry, and balloon expulsion test, and complications recorded after BTX-A injection.RESULTS: Seven studies comprising 189 patients were included in the review. The median age of the patients was 41.2 years and female-to-male ratio was 1.3:1. The median dose of BTX-A injected per procedure was 100 IU(range, 20-100 IU). Lateral injection was done in five trails and combined lateral and posterior injections in two trials. Three studies used endorectal ultrasonographyguided technique, one study used EMG-guided technique,whereas the remaining three studies used manual palpation with the index finger. The median percentage of patients who reported initial improvement of symptoms was 77.4%(range 37.5%-86.7%), this percentage declined to a median of 46%(range 25%-100%) at 4 mo after injection of BTX-A. Rates of improvement evaluated by balloon expulsion test, EMG, and defecography ranged between(37.5%-80%),(54%-86.7%), and(25%-86.6%), respectively. Fourteen(7.4%) patients developed complications after injection of BTX-A. Complication rates across the studies ranged from 0% to 22.6%. CONCLUSION: Initial satisfactory improvement of symptoms after BTX-A injection remarkably deteriorated after 3 mo of the procedure. However, repeated injection may provide better sustained results with no additional morbidities. Further analysis of more patients is necessary to conclude the safety of BTX-A for the treatment of anismus. | Sameh Hany Emile Hossam Ayman Elfeki Hosam Ghazy Elbanna Mohamed Youssef Waleed Thabet Tito M Abd El-Hamed Basem Said Ahmed Lotfy | 2016 | World Journal of Gastrointestinal Pharmacology and Therapeutics2016，7，3： | 3 |
| 20 | Effect of the Si/Al ratio of HZSM-5 zeolite on the production of dimethyl ether before and after ultrasonication显示文摘A series of as-synthesized HZSM-5 zeolites with different Si/Al ratios(25,90,120,240 and 400)were post-treated by ultrasonication for an optimum time of 60 min.The morphology,acidity and textural properties of HZSM-5 were characterized with XRD,SEM,N_2 adsorption and NH3-TPD techniques.The catalytic performance was evaluated by dehydration of methanol to dimethyl ether(DME),which is a promising gaseous automotive fuel in future.It was found that the Si/Al ratio of HZSM-5 had considerable impacts on its catalytic performance for dehydration of methanol to DME.Its activity increased with decreasing Si/Al ratio from 400 to 25.Ultrasonication of HZSM-5 could significantly improve its catalytic performance. | Sameh M.K.Aboul-Fotouh Laila I.Ali Mona A.Naghmash Noha A.K.Aboul-Gheit | 2017 | 燃料化学学报2017，45，5： | 3 |
