| 2 | 高掺量粉煤灰高延性水泥基复合材料的制备和性能显示文摘高延性水泥基复合材料(high ductility cementitious composites,HDCC)是一种具有应变硬化、多缝开裂和高延性等特性的新型纤维增强水泥基复合材料,其材料设计必须取得基体韧度、界面黏结和纤维特性三者的最优组合,因此,HDCC的制备必须优选原材料和优化配合比,以取得最优的材料制备技术。从配合比设计入手,研究了粉煤灰含量、胶砂比等对HDCC力学性能的影响,优化了特定材料下的材料制备技术。结果表明:粉煤灰含量、胶砂比和养护条件对HDCC的拉伸性能均具有较大的影响。随着粉煤灰掺量的增大,砂含量的降低,拉伸应变增大。当砂含量较高时,基体开裂韧度较高,基体的极限拉伸应力下对应的极限拉伸应变较小,然而随着应力的下降,复合材料仍然能维持相当大的应变。 | 庞超明 LEUNG C K Y 孙伟 | 2009 | 硅酸盐学报2009,37,12: | 30 |

| 4 | Helicobacter pylori associated gastric intestinal metaplasia:Treatment and surveillance显示文摘Gastric cancer(GC) is one of the leading causes of cancer related death in the world, particularly in East Asia. According to the Correa's cancer cascade, noncardia GC is usually developed through a series of mucosal changes from non-atrophic gastritis to atrophic gastritis(AG), intestinal metaplasia(IM), dysplasia and adenocarcinoma. Atrophic gastritis and IM are therefore generally considered to be pre-neoplastic gastric lesions. Helicobacter pylori(H. pylori) infection is an important initiating and promoting step of this gastric carcinogenesis cascade. Emerging long-term data showed that eradication of H. pylori reduced the risk of subsequent cancer development. It however remains confusing whether eradication of the bacterium in individuals with pre-neoplastic gastric lesions could regress these changes as well as in preventing cancer. Whilst H. pylori eradication could likely regress AG, the presence of IM may be a point of no return in this cascade. Hence, surveillance by endoscopy may be indicated in those with extensive IM or those with incomplete IM, particularly in populations with high GC risk. The optimal interval and the best tool of surveillance endoscopy remains to be determined in future studies. | Kevin Sze-Hang Liu Irene Oi-Ling Wong Wai K Leung | 2016 | World Journal of Gastroenterology2016,22,3: | 23 |
| 5 | Effect of oral erythromycin on gastric and small bowel transit time of capsule endoscopy显示文摘AIM: To determine the effect of oral erythromycin on gastric and small bowel transit time of capsule endoscopy.METHODS: Consecutive patients who underwent capsule endoscopy du ring the 16-mo study period were either given 250 mg oral erythromycin, 1 h prior to swallowing the capsule endoscope or nothing. The gastric and small bowel transit time, and the small bowel image quality were compared.RESULTS: Twenty-four patients received oral erythromycin whereas 14 patients were not given any prokinetic agent.Patients who received erythromycin had a significantly lower gastric transit time than control (16 min vs70 min, P= 0.005),whereas the small bowel transit time was comparable between the two groups (227 min vs183 min, P = 0.18).Incomplete small bowel examination was found in three patients of the control group and in one patient of the erythromycin group. There was no significant difference in the overall quality of small bowel images between the two groups. A marked reduction in gastric transit time was noted in two patients who had repeat capsule endoscopy after oral erythromycin.CONCLUSION: Use of oral erythromycin significantly reduces the gastric transit time of capsule endoscopy. | Wai K Leung Francis KL Chan Sara SL Fung Mei-Yin Wong Joseph JY Sung | 2005 | World Journal of Gastroenterology2005,11,31: | 16 |

| 7 | Risk of gastric cancer development after eradication of Helicobacter pylori显示文摘Helicobacter pylori(H. pylori) infection is the most important risk factor for gastric cancer(gc) development through the correa's gastric carcinogenesis cascade. However, H. pylori eradication alone does not eliminate gc, as pre-neoplastic lesions(atrophic gastritis, intestinal metaplasia and dysplasia) may have already developed in some patients. It is therefore necessary to identify patients at high-risk for gastric cancer after H. pylori eradication to streamline the management plan. If the patients have not undergone endoscopy with histologic assessment, the identification of certain clinical risk factors and non-invasive testing(serum pepsinogen) can predict the risk of atrophic gastritis. For those with suspected atrophic gastritis, further risk stratification by endoscopy with histologic assessment according to validated histologic staging systems would be advisable. Patients with higher stages may require long-term endoscopic surveillance. Apart from secondary prevention to reduce deaths by diagnosing gc at an early stage, identifying medications that could potentially modify the gc risk would be desirable. The potential roles of a number of medications have been suggested by various studies, including proton pump inhibitors(PPIs), aspirin, statins and metformin. However, there are currently no randomized clinical trials to address the impact of these medications on gc risk after H. pylori eradication. In addition, most of these studies failed to adjust for the effect of concurrent medications on gc risk. Recently, large population-based retrospective cohort studies have shown that PPIs were associated with an increased gc risk after H. pylori eradication, while aspirin was associated with a lower risk. The roles of other agents in reducing gc risk after H. pylori eradication remain to be determined. | Ka-Shing cheung Wai K Leung | 2018 | World Journal of Gastrointestinal Oncology2018,10,5: | 13 |

| 9 | Potential Use of Strain Hardening ECC in Permanent Formwork with Small Scale Flexural Beams显示文摘Utilizing pre-cast ECC panels as participating permanent formwork of concrete members, and the validity of using ECC to disperse the single crack in concrete into multiple ones in ECC were studied. In the process, totally two kinds of ECC with different tensile properties, 7 series of flat panels with different top surface figures and 3 U-shape panels with different inner surface forms were investigated. To evaluate the performance of the permanent formworks, small ECC-concrete composite beams were cast and tested mechanically. The 4-point bending test results show that the use of pre-cast ECC panels as permanent formwork can significantly improve the load capacity and toughness of a concrete member, effectively dispersing single widely opened crack in concrete into multiple ones in ECC. Most permanent formworks show perfect bond with the concrete cast on them, while the ones with partially debonded zone achieve the best mechanical performance. The U-shape permanent formworks show better performances than the flat ones, achieving much betler improvements in both the load capacity and toughness, together with better crack width control. | 李贺东 Christopher K Y Leung | 2009 | Journal of Wuhan University of Technology(Materials Science)2009,24,3: | 8 |
| 10 | Gastrointestinal bleeding in patients on novel oral anticoagulants:Risk,prevention and management显示文摘Novel oral anticoagulants(NOACs), which include direct thrombin inhibitor(dabigatran) and direct factor Xa inhibitors(rivaroxaban, apixaban and edoxaban), are gaining popularity in the prevention of embolic stroke in non-valvular atrial fibrillation as well as in the prevention and treatment of venous thromboembolism. However, similar to traditional anticoagulants, NOACs have the side effects of bleeding, including gastrointestinal bleeding(GIB). Results from both randomized clinical trials and observations studies suggest that high-dose dabigatran(150 mg b.i.d), rivaroxaban and high-dose edoxaban(60 mg daily) are associated with a higher risk of GIB compared with warfarin. Other risk factors of NOAC-related GIB include concomitant use of ulcerogenic agents, older age, renal impairment, Helicobacter pylori infection and a past history of GIB. Prevention of NOAC-related GIB includes proper patient selection, using a lower dose of certain NOACs and in patients with renal impairment, correction of modifiable risk factors, and prescription of gastroprotective agents. Overt GIB can be managed by withholding NOACs followed by delayed endoscopic treatment. In severe bleeding, additional measures include administration of activated charcoal, use of specific reversal agents such as idarucizumab for dabigatran and andexanent alfa for factor Xa inhibitors, and urgent endoscopic management. | Ka-Shing Cheung Wai K Leung | 2017 | World Journal of Gastroenterology2017,23,11: | 8 |

| 19 | Is artificial intelligence the final answer to missed polyps in colonoscopy?显示文摘Lesions missed by colonoscopy are one of the main reasons for post-colonoscopy colorectal cancer,which is usually associated with a worse prognosis.Because the adenoma miss rate could be as high as 26%,it has been noted that endoscopists with higher adenoma detection rates are usually associated with lower adenoma miss rates.Artificial intelligence(AI),particularly the deep learning model,is a promising innovation in colonoscopy.Recent studies have shown that AI is not only accurate in colorectal polyp detection but can also reduce the miss rate.Nevertheless,the application of AI in real-time detection has been hindered by heterogeneity of the AI models and study design as well as a lack of long-term outcomes.Herein,we discussed the principle of various AI models and systematically reviewed the current data on the use of AI on colorectal polyp detection and miss rates.The limitations and future prospects of AI on colorectal polyp detection are also discussed. | Thomas K L Lui Wai K Leung | 2020 | World Journal of Gastroenterology2020,26,35: | 2 |
