| 1 | Enzymatic activity and chromatographic characteristics of the cell membrane immobilized on silica surface显示文摘A new cell membrane preparation, silica carrier cell membrane (CCM), has been presented, in which cell membrane was immobilized on silica which acted as carrier by the adsorption. The surface characteristics of the silica CCM have been tested by a scanning electron microscope and surface energy spectrometer. Comparison has been made of the changeable rule of enzymatic activity of rabbit red cell membrane in three states: the silica CCM, the suspension and the precipitation cell membranes, with temperature and time. The result showed that the silica CCM still keeps the same enzymatic activity as the other two states of cell membranes. The interactions between calcium antagonists and rabbit red and cardiac muscle cell membranes, and the stereoscopic interactions between dihydropridines and rabbit cerebellar cell membrane have been investigated by the chromatographic system of the silica CCM as a stationary phase. From the foregoing results, the chromatographic parameters obtained from the system would | Langchong He Guangde Yang Xindu Geng | 1999 | Chinese Science Bulletin1999，44，9： | 58 |
| 2 | Bowel preparation quality scales for colonoscopy显示文摘Colorectal cancer(CRC) is the third most common cancer and second leading cause of cancer-related death in the United States. Colonoscopy is widely preferred for CRC screening and is the most commonly used method in the United States. Adequate bowel preparation is essential for successful colonoscopy CRC screening. However, up to one-quarter of colonoscopies are associated with inadequate bowel preparation, which may result in reduced polyp and adenoma detection rates, unsuccessful screens, and an increased likelihood of repeat procedure. In addition, standardized criteria and assessment scales for bowel preparation quality are lacking. While several bowel preparation quality scales are referred to in the literature, these differ greatly in grading methodology and categorization criteria. Published reliability and validity data are available for five bowel preparation quality assessment scales, which vary in several key attributes. However, clinicians and researchers continue to use a variety of bowel preparation quality measures, including nonvalidated scales, leading to potential confusion and difficulty when comparing quality results among clinicians and across clinical trials. Optimal clinical criteria for bowel preparation quality remain controversial. The use of validated bowel preparation quality scales with stringent but simple scoring criteria would help clarify clinical trial data as well as the performance of colonoscopy in clinical practice related to quality measurements. | David Kastenberg Gerald Bertiger Stuart Brogadir | 2018 | World Journal of Gastroenterology2018，24，26： | 38 |
| 3 | Impact of mechanical bowel preparation in elective colorectal surgery:A meta-analysis显示文摘AIM To analyse the effect of mechanical bowel preparation vs no mechanical bowel preparation on outcome in patients undergoing elective colorectal surgery.METHODS Meta-analysis of randomised controlled trials and observational studies comparing adult patients receiving mechanical bowel preparation with those receiving no mechanical bowel preparation, subdivided into those receiving a single rectal enema and those who received no preparation at all prior to elective colorectal surgery. RESULTS A total of 36 studies(23 randomised controlled trials and 13 observational studies) including 21568 patients undergoing elective colorectal surgery were included. When all studies were considered, mechanical bowel preparation was not associated with any significant difference in anastomotic leak rates(OR = 0.90, 95%CI: 0.74 to 1.10, P = 0.32), surgical site infection(OR = 0.99, 95%CI: 0.80 to 1.24, P = 0.96), intraabdominal collection(OR = 0.86, 95%CI: 0.63 to 1.17, P = 0.34), mortality(OR = 0.85, 95%CI: 0.57 to 1.27, P = 0.43), reoperation(OR = 0.91, 95%CI: 0.75 to 1.12, P = 0.38) or hospital length of stay(overall mean difference 0.11 d, 95%CI:-0.51 to 0.73, P = 0.72), when compared with no mechanical bowel preparation, nor when evidence from just randomized controlledtrials was analysed. A sub-analysis of mechanical bowel preparation vs absolutely no preparation or a single rectal enema similarly revealed no differences in clinical outcome measures. CONCLUSION In the most comprehensive meta-analysis of mechanical bowel preparation in elective colorectal surgery to date, this study has suggested that the use of mechanical bowel preparation does not affect the incidence of postoperative complications when compared with no preparation. Hence, mechanical bowel preparation should not be administered routinely prior to elective colorectal surgery. | Katie E Rollins Hannah Javanmard-Emamghissi Dileep N Lobo | 2018 | World Journal of Gastroenterology2018，24，4： | 33 |
| 4 | Minimal invasive microscopic tooth preparation in esthetic restoration: a specialist consensus显示文摘By removing a part of the structure,the tooth preparation provides restorative space,bonding surface,and finish line for various restorations on abutment.Preparation technique plays critical role in achieving the optimal result of tooth preparation.With successful application of microscope in endodontics for>30 years,there is a full expectation of microscopic dentistry.However,as relatively little progress has been made in the application of microscopic dentistry in prosthodontics,the following assumptions have been proposed:Is it suitable to choose the tooth preparation technique under the naked eye in the microscopic vision?Is there a more accurate preparation technology intended for the microscope?To obtain long-term stable therapeutic effects,is it much easier to achieve maximum tooth preservation and retinal protection and maintain periodontal tissue and oral function health under microscopic vision?Whether the microscopic prosthodontics is a gimmick or a breakthrough in obtaining an ideal tooth preparation should be resolved in microscopic tooth preparation.This article attempts to illustrate the concept,core elements,and indications of microscopic minimally invasive tooth preparation,physiological basis of dental pulp,periodontium and functions involved in tool preparation,position ergonomics and visual basis for dentists,comparison of tooth preparation by naked eyes and a microscope,and comparison of different designs of microscopic minimally invasive tooth preparation techniques.Furthermore,a clinical protocol for microscopic minimally invasive tooth preparation based on target restorative space guide plate has been put forward and new insights on the quantity and shape of microscopic minimally invasive tooth preparation has been provided. | Haiyang Yu Yuwei Zhao Junying Li Tian Luo Jing Gao Hongchen Liu Weicai Liu Feng Liu Ke Zhao Fei Liu Chufan Ma Juergen MSetz Shanshan Liang Lin Fan Shanshan Gao Zhuoli Zhu Jiefei Shen Jian Wang Zhimin Zhu Xuedong Zhou | 2019 | International Journal of Oral Science2019，11，4： | 25 |
| 5 | Oral purgative and simethicone before small bowel capsule endoscopy显示文摘AIM:To evaluate small bowel cleansing quality,diagnostic yield and transit time,comparing three cleansing protocols prior to capsule endoscopy.METHODS:Sixty patients were prospectively enrolled and randomized to one of the following cleansing protocols:patients in Group A underwent a 24 h liquid diet and overnight fasting;patients in Group B followed protocol A and subsequently were administered 2 L of polyethylene glycol(PEG) the evening before the procedure;patients in Group C followed protocol B and were additionally administered 100 mg of simethicone 30 min prior to capsule ingestion.Small bowel cleansing was independently assessed by two experienced endoscopists and classified as poor,fair,good or excellent according to the proportion of small bowel mucosa under perfect conditions for visualization.When there was no agreement between the two endoscopists,the images were reviewed and discussed until a consensus was reached.The preparation was considered acceptable if > 50% or adequate if > 75% of the mucosa was in perfect cleansing condition.The amount of bubbles was assessed independently and it was considered significant if it prevented a correct interpretation of the images.Positive endoscopic findings,gastric emptying time(GET) and small bowel transit time(SBTT) were recorded for each examination.RESULTS:There was a trend favoring Group B in achieving an acceptable(including fair,good or excellent) level of cleansing(Group A:65%;Group B:83.3%;Group C:68.4%) [P = not significant(NS)] and favoring Group C in attaining an excellent level of cleansing(Group A:10%;Group B:16.7%;Group C:21.1%)(P = NS).The number of patients with an adequate cleansing of the small bowel,corresponding to an excellent or good classification,was 5(25%) in Group A,5(27.8%) in Group B and 4(21.1%) in Group C(P = 0.892).Conversely,7 patients(35%) in Group A,3 patients(16.7%) in Group B and 6 patients(31.6%) in Group C were considered to have poor small bowel cleansing(P = 0.417),with significant fluid or debris such that the examination was unreliable.The proportion of patients with a significant amount of bubbles was 50% in Group A,27.8% in Group B and 15.8% in Group C(P = 0.065).This was significantly lower in Group C when compared to Group A(P = 0.026).The mean GET was 27.8 min for Group A,27.2 min for Group B and 40.7 min for Group C(P = 0.381).The mean SBTT was 256.4 min for Group A,256.1 min for Group B and 258.1 min for Group C(P = 0.998).Regarding to the rate of complete examinations,the capsule reached the cecum in 20 patients(100%) in Group A,16 patients(88.9%) in Group B and 17 patients(89.5%) in Group C(P = 0.312).A definite diagnosis based on relevant small bowel endoscopic lesions was established in 60% of the patients in Group A(12 patients),44.4% in Group B(8 patients) and 57.8% in Group C(11 patients)(P = 0.587).CONCLUSION:Preparation with 2 L of PEG before small bowel capsule endoscopy(SBCE) may improve small bowel cleansing and the quality of visualization.Simethicone may further reduce intraluminal bubbles.No significant differences were found regarding GET,SBTT and the proportion of complete exploration or diagnostic yield among the three different cleansing protocols. | Bruno Joel Ferreira Rosa Mara Barbosa Joana Magalhes Ana Rebelo Maria Joo Moreira José Cotter | 2013 | World Journal of Gastrointestinal Endoscopy2013，5，2： | 21 |
| 6 | Preparation and Properties of Cellulose Nanomaterials显示文摘Cellulose is the most abundant biomass material in nature and it is mainly extracted from natural or lignocellulosic fibers.After purification,cellulose fibers exhibit two interesting features for their further transformation into nanomaterials:a hierarchical and multi-level strcture,and a semicrystalline microstructure.Different forms of cellulose nanomaterials,resulting from a top-down deconstructing strategy(cellulose nanocrystals(CNCs),cellulose nanofibrils(CNFs))or bottom-up strategy(bacterial cellulose(BC))can be prepared.Multiple mechanical shearing actions applied to cellulosic fibers release more or less the nanofibrils individually.A controlled strong acid hydrolysis treatment can be applied to cellulosic fibers allowing dissolution of non-crystalline domains.Such cellulose nanomaterials have been the focus of an exponentially increasing number of works or reviews devoted to understand such materials and their applications.They have a high potential for an emerging industry.In the nanoscale,cellulose exhibits specific properties broadening the applications of this naturally occurring polymer.An overview of existing methods for the preparation of cellulose nanomaterials and their specific properties that outperform and contrast with cellulose in the microscale is proposed. | Alain Dufresne | 2020 | Paper And Biomaterials2020，5，3： | 19 |
| 7 | Bowel cleansing before colonoscopy:Balancing efficacy,safety,cost and patient tolerance显示文摘Effective colorectal cancer screening relies on reliable colonoscopy findings which are themselves dependent on adequate bowel cleansing. Research has consistently demonstrated that inadequate bowel preparation adversely affects the adenoma detection rate and leads gastroenterologists to recommend earlier follow up than is consistent with published guidelines. Poor preparation affects as many as 30% of colonoscopies and contributes to an increased cost of colonoscopies. Patient tolerability is strongly affected by the preparation chosen and manner in which it is administered. Poor tolerability is,in turn,associated with lower quality bowel preparations. Recently,several new developments in both agents being used for bowel preparation and in the timing of administration have brought endoscopists closer to achieving the goal of effective,reliable,safe,and tolerable regimens. Historically,large volume preparations given in a single dose were administered to patients in order to achieve adequate bowel cleansing. These were poorly tolerated,and the unpleasant taste of and significant side effects produced by these large volume regimens contributed significantly to patients' inability to reliably complete the preparation and to a reluctance to repeat the procedure. Smaller volumes,including preparations that are administered as tablets to be consumed with water,given as split doses have significantly improved both the patient experience and efficacy,and an appreciation of the importance of the preparation to colonoscopy interval have produced additional cleansing. | Nicole M Harrison Michael C Hjelkrem | 2016 | World Journal of Gastrointestinal Endoscopy2016，8，1： | 19 |
| 8 | Progress in Nanocellulose Preparation and Application显示文摘Nanocellulose is a biodegradable, renewable, nonmeltable polymeric material that is insoluble in most solvents due to hydrogen bonding and crystallinity. Nanocellulose has attracted considerable attention in recent decades owing to its environmental friendliness, wide availability, good biocompatibility, high crystallinity, and high Young's modulus. This review presents the recent achievements in preparation and applications of nanocellulose, including a discussion of the advantages and disadvantages of various preparation methods and a summary of the applications of nanocellulose in composite materials research. Finally, we examine the mounting evidence of more widespread potential applications of nanocellulose. | HaiQuan Mao YongYang Gong YuanLi Liu ShiQi Wang LinLin Du Chun Wei | 2017 | Paper And Biomaterials2017，2，4： | 19 |

| 10 | Small-bowel capsule endoscopy: A ten-point contemporary review显示文摘The introduction of capsule endoscopy (CE) in clinical practice increased the interest for the study of the small-bowel. Consequently, in about 10 years, an impressive quantity of literature on indications, diagnostic yield (DY), safety profile and technical evolution of CE has been published as well as several reviews. At present time, there are 5 small-bowel capsule enteroscopy (SBCE) models in the worldwide market. Head-to-head trials have showed in the great majority of studies comparable results in terms of DY, image quality and completion rate. CE meta-analyses formed the basis of national/international guidelines; these guidelines place CE in a prime position for the diagnostic work-up of patients with obscure gastrointestinal bleeding, known and/or suspected Crohn's disease and possible small-bowel neoplasia. A 2-L polyethylene glycol-based purge, administered the day before the procedure,is the most widely practiced preparation regimen. Whether this regimen can be further improved (i.e. , by further decreasing its volume, changing the timing of administration, coupling it with prokinetics and/or other factors) or if it can really affect the DY, is still under discussion. Faecal calprotectin has been used in SBCE studies in two settings: in patients taking non-steroidal anti-inflammatory drugs, to evaluate the type and extent of mucosal damage and, more importantly from a clinical point of view, in patients with known or suspected Crohn's disease for assessment of inflam-mation activity. Although there is still a lot of debate around the exact reasons of SBCE poor performance in various small-bowel segments, it is worth to remember that the capsule progress is non-steerable, hence more rapid in the proximal than in lower segments of the small-bowel. Capsule aspiration, a relatively unexpected complication, has been reported with increasing frequency. This is probably related with the increase in the mean age of patients undergoing CE. CE video review is a time-consuming procedure. Therefore, several attempts have been made to develop technical software features, in order to make CE video analysis easier and shorter (without jeopardizing its accuracy). Suspected Blood Indicator, QuickView and Fujinon Intelligent Chromo Endoscopy are some of the software tools that have been checked in various clinical studies to date. | Anastasios Koulaouzidis Emanuele Rondonotti Alexandros Karargyris | 2013 | World Journal of Gastroenterology2013，19，24： | 14 |
| 11 | Recent advances in cell sheet technology for bone and cartilage regeneration: from preparation to application显示文摘Bone defects caused by trauma,tumour resection,infection and congenital deformities,together with articular cartilage defects and cartilage–subchondral bone complex defects caused by trauma and degenerative diseases,remain great challenges for clinicians.Novel strategies utilising cell sheet technology to enhance bone and cartilage regeneration are being developed.The cell sheet technology has shown great clinical potential in regenerative medicine due to its effective preservation of cell–cell connections and extracellular matrix and its scaffold-free nature.This review will first introduce several widely used cell sheet preparation systems,including traditional approaches and recent improvements,as well as their advantages and shortcomings.Recent advances in utilising cell sheet technology to regenerate bone or cartilage defects and bone–cartilage complex defects will be reviewed.The key challenges and future research directions for the application of cell sheet technology in bone and cartilage regeneration will also be discussed. | Yuezhi Lu Wenjie Zhang Jie Wang Guangzheng Yang Shi Yin Tingting Tang Chunhua Yu Xinquan Jiang | 2019 | International Journal of Oral Science2019，11，2： | 14 |
| 12 | Role of endoscopy in acute gastrointestinal bleeding in real clinical practice:An evidence-based review显示文摘Although upper gastrointestinal bleeding is usually segregated from lower gastrointestinal bleeding, and guidelines for gastrointestinal bleeding are divided into two separate sections, they may not be distinguished from each other in clinical practice. Most patients are first observed with signs of bleeding such as hematemesis, melena, and hematochezia. When a patient with these symptoms presents to the emergency room, endoscopic diagnosis and treatment are considered together with appropriate initial resuscitation. Especially, in cases of variceal bleeding, it is important for the prognosis that the endoscopy is performed immediately after the patient stabilizes. In cases of suspected lower gastrointestinal bleeding, full colonoscopy after bowel preparation is effective in distinguishing the cause of the bleeding and treating with hemostasis. The therapeutic aspect of endoscopy, using the mechanical method alone or injection with a certain modality rather than injection alone, can increase the success rate of bleeding control. Therefore, it is important to consider the origin of bleeding and how to approach it. In this article, we aim to review the role of endoscopy in diagnosis, treatment, and prognosis in patients with acute gastrointestinal bleeding in a real clinical setting. | Kyoungwon Jung Won Moon | 2019 | World Journal of Gastrointestinal Endoscopy2019，11，2： | 13 |
| 13 | Factors influencing quality of bowel preparation for colonoscopy显示文摘Recent technological advances in colonoscopy have led to improvements in both image enhancement and procedural performance.However,the utility of these technological advancements remain dependent on the quality of bowel preparation during colonoscopy.Poor bowel preparation has been shown to be associated with lower quality indicators of colonoscopy performance,such as reduced cecal intubation rates,increased patient discomfort and lower adenoma detection.The most popular bowel preparation regimes currently used are based on either Polyethylene glycol-electrolyte,a non-absorbable solution,or aqueous sodium phosphate,a lowvolume hyperosmotic solution.Statements from various international societies and several reviews have suggested that the efficacy of bowel preparation regimes based on both purgatives are similar,although patients' compliance with these regimes may differ somewhat.Many studies have now shown that factors other than the type of bowel preparation regime used,can influence the quality of bowel preparation among adult patients undergoing colonoscopy.These factors can be broadly categorized as either patient-related or procedure-related.Studies from both Asia and the West have identified patient-related factors such as an increased age,male gender,presence of co-morbidity and socioeconomic status of patients to be associated with poor bowel preparation among adults undergoing routine out-patient colonoscopy.Additionally,procedure-related factors such as adherence to bowel preparation instructions,timing of bowel purgative administration and appointment waiting times for colonoscopy are recognized to influence the quality of colon cleansing.Knowledge of these factors should aid clinicians in modifying bowel preparation regimes accordingly,such that the quality of colonoscopy performance and delivery of service to patients can be optimised. | Ronald V Romero Sanjiv Mahadeva | 2013 | World Journal of Gastrointestinal Endoscopy2013，5，2： | 13 |

| 15 | Effect of preparation method on physicochemical properties and catalytic performances of LaCoO3 perovskite for CO oxidation显示文摘Perovskite oxides LaCoO3 prepared by templating,co-precipitation and sol-gel method with different complexants were systematically characterized and its catalytic performances for CO oxidation were investigated.The samples were characterized by X-ray diffraction,thermogravimetry analysis and differential scanning calorimetry,N2 physisorption,transmission electron microscopy,temperature program reduction of hydrogen,temperature program desorption of oxygen and X-ray photoelectron spectroscopy measurement,results of which show that the properties of LaCoO3,such as surface morphology,surface area,surface compositions,redox capability,oxygen vacancy,as well as the calcination temperature and formation mechanism,depend intimately on the preparation method.Catalytic tests indicate that the sample prepared by carbon templating method shows the best activity for CO oxidation,with full CO conversion obtained at 135℃.In particular,the catalyst can be activated and significant increase of activity can be obtained with the increase of reaction time.The cyclic and longterm stability of catalysts were discussed and compared. | Shan Wang Xuelian Xu Junjiang Zhu Duihai Tang Zhen Zhao | 2019 | Journal of Rare Earths2019，37，9： | 10 |
| 16 | Mn-Ce-Nb-O_x/P84 catalytic filters prepared by a novel method for simultaneous removal of particulates and NO显示文摘The Mn-Ce-Nb-O_x/P84 catalytic filter for removal of particulates and NO simultaneous was prepared by a novel method(foam coating method). The process parameters including the concentrations of PTFE emulsion, particle size of catalyst and calcination temperature for preparation of catalytic filters were analyzed. In addition, the physical properties and performance for removal of NO(NH_3-SCR) and particulates of Mn-Ce-Nb-O_x/P84 catalytic filter prepared under the optimized parameters, were also systematic studied. Results show that the process parameters had significant influences on stability and performance of catalytic filter, The Mn-Ce-Nb-O_x/P84 catalytic filter prepared by foam coating method under the optimized parameters, has satisfactory physical properties and catalytic performance for removal of NO and particulates at 140-220 ℃. The NO removal efficiency of catalytic filter can reach95.3% at 200 ℃ as the catalyst loading amount is 450 g/m^2, Moreover,the dust removal efficiency of MnGe-Nb-O_x/P84 catalytic filter reaches as high as 99.98%, and the PM2.5 removal efficiency also reaches99.98%. The anti-sulfur performance of Mn-Ce-Nb-O_x catalytic filter is also attractive, after injecting150 ppm SO_2, the NO removal efficiency still retains up to 85%. It is indicated that the foam coating method can not only make a bond of high strength between catalyst and filter, but also make the catalytic filter possessing an excellent and stable performance for removal of NO and particulates. | Bo Yang Qiong Huang Mindong Chen Yuesong Shen Shemin Zhu | 2019 | Journal of Rare Earths2019，37，3： | 10 |
| 17 | Bowel preparation prior to colonoscopy:A continual search for excellence显示文摘Bowel preparation prior to colonoscopy is essential to maximize the benefits of colonoscopy.Numerous bowel preparations have been studied,ranging from 4 L polyethylene glycol(PEG) to split-dose regimens to 2 L PEG with an adjunct laxative(senna,bisacodyl,ascorbic acid).Due to the large volume of PEG required for adequate bowel preparation,many studies have focused on reducing this large volume to only 2 L PEG with the addition of an adjunct.Recently,a randomized controlled trial by Tajika et al showed that the addition of mosapride to only 1.5 L PEG was non-inferior to mosapride and 2 L PEG for bowel cleansing but did provide improvements in patient tolerance.This study offers yet another potential bowel preparation for patients undergoing colonoscopy and may trigger further studies with 1.5 L PEG with an adjunct.In this letter,we discuss the current state of bowel preparation prior to colonoscopy and offer information to guide clinicians on choosing the appropriate bowel preparation for their patients. | Matthew L Bechtold Abhishek Choudhary | 2013 | World Journal of Gastroenterology2013，19，2： | 9 |
| 18 | Alginate oligosaccharides preparation, biological activities and their application in livestock and poultry显示文摘Alginate oligosaccharides(AOS), belonging to the class of functional marine oligosaccharides, are low-molecular polymers linked by β-1,4-mannuronic acid(M) and α-1,4-guluronic acid(G), which could be classically obtained by enzymatic hydrolysis of alginate. With low viscosity and good water solubility, as well as anti-oxidant, immune regulation, anti-bacterial and antiinflammatory activities, AOS have been widely used in medical science and functional food, green agriculture and other fields. As new bio-feed additives, AOS have broad potential applications in animal husbandry. In this review, the sources of alginate, chemical structure and preparation methods of AOS, and their biological activities and application in livestock and poultry are summarized. We expect this review could contribute to lay a foundation of application and further research for AOS in livestock and poultry. | LIU Ming LIU Lei ZHANG Hong-fu YI Bao Nadia EVERAERT | 2021 | Journal of Integrative Agriculture2021，20，1： | 9 |

| 20 | Comparison of split-dosing vs non-split(morning) dosing regimen for assessment of quality of bowel preparation for colonoscopy显示文摘AIM: To compare(using the Ottawa Bowel Preparation Scale) the efficacy of split-dose vs morning administration of polyethylene glycol solution for colon cleansing in patients undergoing colonoscopy, and to assess the optimal preparation-to-colonoscopy interval.METHODS: Single-centre, prospective, randomized, investigator-blind stud in an academic tertiarycare centre. Two hundred patients requiring elective colonoscopy were assigned to receive one of the two preparation regimens(split vs morning) prior to colonoscopy. Main outcome measurements were bowel preparation quality and patient tolerability.RESULTS: Split-dose regimen resulted in better bowel preparation compared to morning regimen [Ottawascore mean 5.52(SD 1.23) vs 6.02(1.34); P = 0.017]. On subgroup analysis, for afternoon procedures, both the preparations were equally effective(P = 0.756). There was no difference in tolerability and compliance between the two regimens.CONCLUSION: Overall, previous evening- same morning split-dosing regimen results in better bowel cleansing for colonoscopy compared to morning preparation. For afternoon procedures, both schedules are equally effective; morning preparation may be more convenient to the patient. | Hardik Shah Devendra Desai Hrishikesh Samant Sandeep Davavala Anand Joshi Tarun Gupta Philip Abraham | 2014 | World Journal of Gastrointestinal Endoscopy2014，6，12： | 8 |
