| 1 | 不同保护性耕作措施对旱作农田土壤水分的影响显示文摘研究了黄土高原西部旱农区传统耕作措施和五种保护性耕作措施对土壤水分垂直分布、动态变化、作物耗水量、水分利用效率及作物产量的影响.结果表明,不同保护性耕作措施对表层0~10cm土壤水分含量影响较大,免耕秸秆覆盖(NTS)在作物播种期可以显著增加播种期表层土壤含水量.0~200cm土壤剖面贮水量年变化分春夏作物旺盛生长失墒期(5月中旬~7月中旬)、夏秋雨季增墒期(7月中旬~10月下旬)和冬春稳墒期(11月~翌年5月上旬)3个阶段.尽管不同保护性耕作措施对0~200cm剖面贮水量影响不大,但作物耗水量却存在显著差异.免耕秸秆覆盖在增加作物耗水量的同时也提高了作物产量以及水分利用效率.地膜覆盖在有些年份也有利于降水的高效利用和作物产量的提高,但与秸秆覆盖相比不利于土壤肥力的持续提高.而且,如果种植小麦,出苗前若一次性降水较多时地膜覆盖将造成严重板结,影响出苗,进而降低产量和水分利用效率.因此,在黄土高原西部旱农区实施免耕+秸秆覆盖的保护性耕作措施,既有利于作物对有限降水的高效利用,提高作物产量,也可以促进农业可持续发展. | 李玲玲 黄高宝 张仁陟 晋小军 Guangdi LI Kwong Yin CHAN | 2005 | 生态学报2005，25，9： | 160 |
| 2 | 免耕秸秆覆盖对旱作农田土壤水分的影响显示文摘通过20012004年的田间试验研究了免耕秸秆覆盖旱作农田的土壤水分效应。结果表明,免耕秸秆覆盖对表层土壤水分含量影响较大,在作物播种期可以减少表层水分蒸发,显著增加表层土壤含水量,但随着生育进程的推进,秸秆覆盖的抑蒸效果逐渐减弱。免耕秸秆覆盖对各个时期0200 cm土壤剖面上水分总量的影响不大,但年际间变化较大。采用免耕秸秆覆盖可以提高小麦-豌豆轮作系统作物产量以及水分利用效率、促进农田生态系统的良性循环,持续提高土壤肥力。 | 李玲玲 黄高宝 张仁陟 晋小军 Guangdi LI Kwong Yin CHAN | 2005 | 水土保持学报2005，19，5： | 103 |
| 3 | 免耕秸秆覆盖对旱作麦田土壤温度的影响显示文摘通过2001~2004年的大田试验研究了免耕秸秆覆盖对黄土高原西部旱地麦田土壤温度的影响。结果表明,土壤温度与气温关系密切;雨季土壤贮水多会导致土壤比热增大而来年早春地温回升慢;免耕秸秆覆盖与传统耕作的地温差不受天气状况的影响。与传统耕作相比,免耕秸秆覆盖可以稳定土壤温度,白天升温较慢,下午至夜间降温更慢。免耕秸秆覆盖降低春小麦全生育期的平均温度0.5℃~1.6℃,拔节至成熟期降低得更多,但对休闲期土壤温度影响不大。免耕秸秆覆盖春小麦经济产量可提高8.8%~28.8%,但产量与耕层平均地温无明显相关性。 | 黄高宝 李玲玲 张仁陟 蔡立群 Guangdi Li Kwong Yin CHAN | 2006 | 干旱地区农业研究2006，24，5： | 65 |
| 4 | 胃癌预防亚太地区共识指南显示文摘背景与目的:胃癌是亚太地区的主要健康负担之一,但对其预防策略尚缺乏共识。本共识会议旨在评价预防胃癌的策略。方法:多学科专家组应用德尔菲(Delphi)法制订共识条文,提呈相关数据,对证据等级、推荐强度以及共识水平予以分级。结果:幽门螺杆菌(H.pylori)感染是非贲门胃腺癌必要但非充分的致病因子。盐的高摄入与胃癌强烈相关。新鲜果蔬对胃癌具有预防作用,但维生素和其他饮食补充并不能预防胃癌。H.pylori感染中的宿主-细菌相互作用导致不同类型的胃炎和胃酸分泌,从而决定疾病结局。胃癌阳性家族史是一个重要的危险因素。低血清胃蛋白酶原反映胃萎缩程度,可作为检出胃癌高危人群的标志物。H.pylori筛查和治疗被推荐作为减少高危人群胃癌危险性的一种策略,该策略在萎缩性胃炎发生前实施最为有效,但并不排除对胃癌高危人群的内镜监测。对胃癌低危人群不推荐行H.pylori筛查。H.pylori感染的一线治疗应遵循国家治疗指南。结论:高危人群中H.pylori筛查和根除策略可能会减少胃癌的发生率,本共识根据现有证据予以推荐。 | Kwong Ming Fock Nick Talley Paul Moayyedi Richard Hunt Takeshi Azuma Kentaro Sugano Shu Dong Xiao Shiu Kum Lam Khean Lee Goh Tsutomu Chiba Naomi Uemura Jae G Kim Nayoung Kim Tiing Leong Ang Varocha Mahachai Hazel Mitchell Abdul Aziz Rani Jyh Ming Liou Ratha-korn Vilaichone Jose Sollanor 钱本余 | 2008 | 胃肠病学2008，13，4： | 37 |
| 5 | 亚太地区胃食管反流病的处理共识:更新版显示文摘背景与目的:自从2004年亚太地区胃食管反流病(GERD)共识发表以来,更多关于GERD流行病学和处理的文献资料相继出现。有必要对这些资料进行循证综述,对共识作出更新。方法:由多学科专家组应用德尔菲(Delphi)法制定共识条文,提呈相关资料,并对证据质量、推荐力度和共识水平进行分级。结果:亚洲GERD发生率日益增加。其危险因素包括老年、男性、种族、家族史、社会经济地位高、体重指数增加和吸烟。对于有典型症状而无报警症状的患者,对质子泵抑制剂(PPI)试验有症状应答具有诊断意义。如PPI试验失败,停止治疗后pH监测结果阴性可排除GERD。窄带成像、胶囊内镜检查和无线pH监测的作用尚未明确。亚洲诊断策略的制定须考虑到并存的胃癌和消化性溃疡。减轻体质量和抬高床头可改善反流症状。PPIs是最有效的内科治疗手段。对于非糜烂性反流病(NERD)患者,按需治疗较为适宜。有慢性咳嗽、喉炎和典型GERD症状的患者在排除非GERD病因后,应予PPI每天两次治疗。如有经验丰富的外科医师,GERD患者可行胃底折叠术。除临床试验外,GERD不应采用内镜治疗。结论:新的诊断方法和内镜治疗的作用有待进一步研究阐明。亚洲GERD诊断策略的制定须考虑到并存的胃癌和消化性溃疡。PPIs仍为治疗的基石。 | Kwong Ming Fock Nicholas J Talley Ronnie Fass Khean Lee Goh Peter Katelaris Richard Hunt Michio Hongo Tiing Leong Ang Gerald Holtmann Sanjay Nandurkar San Ren Lin Benjamin CY Wong Francis KL Chan Abdul Aziz Rani Young-Tae Bak Jose Sollano Khek Yu Ho Sathoporn Manatsathit 钱本余 | 2008 | 胃肠病学2008，13，7： | 21 |
| 6 | Role of LPS/CD14/TLR4-mediated inflammation in necrotizing enterocolitis:Pathogenesis and therapeutic implications显示文摘AIM:To establish the roles of lipopolysaccharide (LPS)/CD14/toll-like receptor 4 (TLR4)-mediated inflammation in a rat model of human necrotizing enterocolitis (NEC).METHODS: Six pairs of intestinal samples from human NEC were collected before and after recovery for histological and molecular analysis of inflammatory cytokines and signaling components. In the rat NEC model, we isolated 10-cm jejunum segments and divided them into six groups (n=6) for sham operation, treatment with LPS, bowel distension, combined bowel distension and LPS stimulation, and two therapeutic groups. The potential eff icacy of a recombinant CD18 peptide and a monoclonal CD14 antibody was evaluated in the latter two groups. The serum and tissue levels of several inflammatory mediators were quantified by real-time polymerase chain reaction, ELISA and immunoblotting.RESULTS: Human acute phase NEC tissues displayed significant increases (P<0.05) in levels of TLR4, CD14, myeloid differentiation protein (MD)-2, tumor necrosis factor (TNF)-α and nuclear factor-κB when compared to those after recovery. The histological and inflammatory picture of human NEC was reproduced in rats that were treated with combined bowel distension and LPS, but not in the sham-operated and other control rats. Serum levels of interleukin-6 and TNF-α were also elevated. The NEC pathology was attenuated by treating the NEC rats with a monoclonal CD14 antibody or an LPS-neutralizing peptide.CONCLUSION:LPS and distension are required to produce the histological and inflammatory features of NEC. A potential treatment option is blocking LPS activation and leukocyte infi ltration. | Kwong L Chan Kwong F Wong John M Luk | 2009 | World Journal of Gastroenterology2009，15，38： | 17 |
| 7 | Benefits of Conservation Agriculture on Soil and Water Conservation and Its Progress in China显示文摘Conservation agriculture has been practised for three decades and has been spread widely. There are many nomenclatures surrounding conservation agriculture and differ to each other lightly. Conservation agriculture (CA) is a system approach to soil and water conservation, high crop productivity and profitability, in one word, it is a system approach to sustainable agriculture. Yet, because conservation agriculture is a knowledge-intensive and a complex system to learn and implement, and also because of traditions of intensive cultivation, adoption rates have been low, since to date, only about seven percent of the world's arable and permanent cropland area is farmed under conservation agriculture. The practice and wider extention of conservation agriculture thus requires a deeper understanding of its ecological underpinnings in order to manage its various elements for sustainable intensification, where the aim is to conserve soil and water and improve sustainability over the long term. This paper described terms related to conservation agriculture, presented the effects of conservation agriculture on soil and water conservation, crop productivity, progress and adoption of CA worldwide, emphasized obstacles and possible ways to increase CA adoption to accelerate sustainable development of China agriculture. | LI Ling-ling HUANG Gao-bao ZHANG Ren-zhi Bill Bellotti Guangdi Li Kwong Yin Chan | 2011 | Agricultural Sciences in China2011，10，6： | 15 |
| 8 | Prostate cancer in Asia:A collaborative report显示文摘The incidence of prostate cancer(PCa)within Asian population used to be much lower than in the Western population;however,in recent years the incidence and mortality rate of PCa in some Asian countries have grown rapidly.This collaborative report summarized the latest epidemiology information,risk factors,and racial differences in PCa diagnosis,current status and new trends in surgery management and novel agents for castration-resistant prostate cancer.We believe such information would be helpful in clinical decision making for urologists and oncologists,health-care ministries and medical researchers. | Rui Chen Shancheng Ren 无 Ming Kwong Yiu Ng Chi Fai Wai Sam Cheng Lap Hong Ian Seiji Naito Tadashi Matsuda Elijah Kehinde Ali Kural Jason Yichun Chiu Rainy Umbas Qiang Wei Xiaolei Shi Liqun Zhou Jian Huang Yiran Huang Liping Xie Lulin Ma Changjun Yin Danfeng Xu Kexin Xu Zhangqun Ye Chunxiao Liu Dingwei Ye Xin Gao Qiang Fu Jianquan Hou Jianlin Yuan Dalin He Tiejun Pan Qiang Ding Fengshuo Jin Benkang Shi Gongxian Wang Xiuheng Liu Dongwen Wang Zhoujun Shen Xiangbo Kong Wanhai Xu Yaoliang Deng Haibo Xia Alexa NCohen Xu Gao Chuanliang Xu Yinghao Sun | 2014 | Asian Journal of Urology2014，1，1： | 13 |
| 9 | Management of granulomatous lobular mastitis: an international multidisciplinary consensus(2021 edition)显示文摘Granulomatous lobular mastitis(GLM) is a rare and chronic benign inflammatory disease of the breast. Difficulties exist in the management of GLM for many front-line surgeons and medical specialists who care for patients with inflammatory disorders of the breast. This consensus is summarized to establish evidence-based recommendations for the management of GLM. Literature was reviewed using PubMed from January 1, 1971 to July 31, 2020. Sixty-six international experienced multidisciplinary experts from 11 countries or regions were invited to review the evidence.Levels of evidence were determined using the American College of Physicians grading system, and recommendations were discussed until consensus. Experts discussed and concluded 30 recommendations on historical definitions,etiology and predisposing factors, diagnosis criteria, treatment, clinical stages, relapse and recurrence of GLM. GLM was recommended as a widely accepted definition. In addition, this consensus introduced a new clinical stages and management algorithm for GLM to provide individual treatment strategies. In conclusion, diagnosis of GLM depends on a combination of history, clinical manifestations, imaging examinations, laboratory examinations and pathology.The approach to treatment of GLM should be applied according to the different clinical stage of GLM. This evidencebased consensus would be valuable to assist front-line surgeons and medical specialists in the optimal management of GLM. | Qian-Qian Yuan Shu-Yuan Xiao Omar Farouk Yu-Tang Du Fereshte Sheybani Qing Ting Tan Sami Akbulut Kenan Cetin Afsaneh Alikhassi Rami Jalal Yaghan Irmak Durur-Subasi Fatih Altintoprak Tae Ik Eom Fatih Alper Mustafa Hasbahceci David Martínez-Ramos Pelin Seher Oztekin Ava Kwong Cedric W.Pluguez-Turul Kirstyn EBrownson Shirish Chandanwale Mehran Habib Liu-Yi Lan Rui Zhou Xian-Tao Zeng Jiao Bai Jun-Wen Bai Qiong-Rong Chen Xing Chen Xiao-Ming Zha Wen-Jie Dai Zhi-Jun Dai Qin-Yu Feng Qing-Jun Gao Run-Fang Gao Bao-San Han Jin-Xuan Hou Wei Hou Hai-Ying Liao Hong Luo Zheng-Ren Liu Jing-Hua Lu Bin Luo Xiao-Peng Ma Jun Qian Jian-Yong Qin Wei Wei Gang Wei Li-Ying Xu Hui-Chao Xue Hua-Wei Yang Wei-Ge Yang Chao-Jie Zhang Fan Zhang Guan-Xin Zhang Shao-Kun Zhang Shu-Qun Zhang Ye-Qiang Zhang Yue-Peng Zhang Sheng-Chu Zhang Dai-Wei Zhao Xiang-Min Zheng Le-Wei Zheng Gao-Ran Xu Wen-Bo Zhou Gao-Song Wu | 2022 | Military Medical Research2022，9，4： | 13 |
| 10 | Bile acids and sphingosine-1-phosphate receptor 2 in hepatic lipid metabolism显示文摘The liver is the central organ involved in lipid metabolism. Dyslipidemia and its related disorders, including non-alcoholic fatty liver disease(NAFLD), obesity and other metabolic diseases, are of increasing public health concern due to their increasing prevalence in the population. Besides their well-characterized functions in cholesterol homoeostasis and nutrient absorption, bile acids are also important metabolic regulators and function as signaling hormones by activating specific nuclear receptors, G-protein coupled receptors, and multiple signaling pathways. Recent studies identified a new signaling pathway by which conjugated bile acids(CBA) activate the extracellular regulated protein kinases(ERK1/2) and protein kinase B(AKT) signaling pathway via sphingosine-1-phosphate receptor 2(S1PR2). CBA-induced activation of S1PR2 is a key regulator of sphingosine kinase 2(Sph K2) andhepatic gene expression. This review focuses on recent findings related to the role of bile acids/S1PR2-mediated signaling pathways in regulating hepatic lipid metabolism. | Eric Kwong Yunzhou Li Phillip B.Hylemon Huiping Zhou | 2015 | Acta Pharmaceutica Sinica B2015，5，2： | 13 |

| 12 | Abnormal subchondral bone remodeling and its association with articular cartilage degradation in knees of type 2 diabetes patients显示文摘Type 2 diabetes(T2 D) is associated with systemic abnormal bone remodeling and bone loss. Meanwhile,abnormal subchondral bone remodeling induces cartilage degradation, resulting in osteoarthritis(OA).Accordingly, we investigated alterations in subchondral bone remodeling, microstructure and strength in knees from T2 D patients and their association with cartilage degradation. Tibial plateaus were collected from knee OA patients undergoing total knee arthroplasty and divided into non-diabetic(n = 70) and diabetes(n = 51) groups. Tibial plateaus were also collected from cadaver donors(n = 20) and used as controls.Subchondral bone microstructure was assessed using micro-computed tomography. Bone strength was evaluated by micro-finite-element analysis. Cartilage degradation was estimated using histology. The expression of tartrate-resistant acidic phosphatase(TRAP), osterix, and osteocalcin were calculated using immunohistochemistry. Osteoarthritis Research Society International(OARSI) scores of lateral tibial plateau did not differ between non-diabetic and diabetes groups, while higher OARSI scores on medial side were detected in diabetes group. Lower bone volume fraction and trabecular number and higher structure model index were found on both sides in diabetes group. These microstructural alterations translated into lower elastic modulus in diabetes group. Moreover, diabetes group had a larger number of TRAP^+ osteoclasts and lower number of Osterix^+ osteoprogenitors and Osteocalcin^+ osteoblasts. T2 D knees are characterized by abnormal subchondral bone remodeling and microstructural and mechanical impairments, which were associated with exacerbated cartilage degradation. In regions with intact cartilage the underlying bone still had abnormal remodeling in diabetes group, suggesting that abnormal bone remodeling may contribute to the early pathogenesis of T2 D-associated knee OA. | Yan Chen Yong-Can Huang Chun Hoi Yan Kwong Yuen Chiu Qingjun Wei Jingmin Zhao X Edward Guo Frankie Leung William W Lu | 2017 | Bone Research2017，5，4： | 10 |

| 14 | Comparative genomic hybridization analysis of genetic aberrations associated with development of esophageal squamous cell carcinoma in Henan, China显示文摘AIM: To characterize cytogenetic alterations in esophageal squamous cell carcinoma (ESCC) and its metastasis. METHODS: A total of 37 cases of primary ESCC and 15 pairs of primary ESCC tumors and their matched metastatic lymph nodes cases were enrolled from Linzhou, the high incidence area for ESCC in Henan, northern China. The comparative genomic hybridization (CGH) was applied to determine the chromosomal aberrations on the DNA extracted from the frozen ESCC and metastatic lymph node samples from these patients. RESULTS: CGH showed chromosomal aberrations in all the cases. In 37 cases of primary ESCC, chromosomal profile of DNA copy number was characterized by frequently detected gains at 8q (29/37, 78%), 3q (24/37, 65%), 5p (19/37, 51%); and frequently detected losses at 3p (21/37, 57%), 8p and 9q (14/37, 38%). In 15 pairs of primary ESCC tumors and their matched metastatic lymph node cases, the majority of the chromosomal aberrations in both primary tumor and metastatic lymph node lesions were consistent with the primary ESCC cases, but new candidate regions of interest were also detected. The most significant finding is the gains of chromosome 6p with a minimum high-level amplification region at 6p12-6q12 in 7 metastatic lymph nodes butonly in 2 corresponding primary tumors (P = 0.05) and 20p with a minimum high-level amplification region at 20p12 in 11 metastatic lymph nodes but only in 5 corresponding primary tumors (P < 0.05). Another interesting finding is the loss of chromosome 10p and 10q in 8 and 7 metastatic lymph nodes but only in 2 corresponding primary tumors (P < 0.05). CONCLUSION: Using the CGH technique to detect chromosomal aberrations in both the primary tumor and its metastatic lymph nodes of ESCC, gains of 8q, 3q and 5p and loss of 3p, 8p, 9q and 13q were specifically implicated in ESCC in Linzhou population. Gains of 6p and 20p and loss of 10pq may contribute to the lymph node metastasis of ESCC. These findings suggest that the gains and losses of chromosomal regions may contain ESCC-related oncogenes and tumor suppressor genes and provide important theoretic information for identifying and cloning novel ESCC-related oncogenes and tumor suppressor genes. | Yan-Ru Qin Li-Dong Wang Zong-Min Fan Dora Kwong Xin-Yuan Guan | 2008 | World Journal of Gastroenterology2008，14，12： | 8 |

| 16 | Tumor suppressor genes on frequently deleted chromosome 3p in nasopharyngeal carcinoma显示文摘Nasopharyngeal carcinoma (NPC) is among the most common malignancies in southern China.Deletion of genomic DNA,which occurs during the complex pathogenesis process for NPC,represents a pivotal mechanism in the inactivation of tumor suppressor genes (TSGs).In many circumstances,loss of TSGs can be detected as diagnostic and prognostic markers in cancer.The short arm of chromosome 3 (3p) is a frequently deleted chromosomal region in NPC,with 3p21.1-21.2 and 3p25.2-26.1 being the most frequently deleted minimal regions.In recent years,our research group and others have focused on the identification and characterization of novel target TSGs at 3p,such as RASSF1A,BLU,RBMS3,and CHL1,in the development and progression of NPC.In this review,we summarize recent findings of TSGs at 3p and discuss some of these genes in detail.A better understanding of TSGs at 3p will significantly improve our understanding of NPC pathogenesis,diagnosis,and treatment. | Juan Chen Li Fu Li-Yi Zhang Dora L.

| 17 | A GLP-1 analog lowers ER stress and enhances protein folding to ameliorate homocysteine-induced endothelial dysfunction显示文摘Hyperhomocysteinemia(HHcy)is an independent risk factor for cardiovascular diseases and increases mortality in type 2 diabetic patients.HHcy induces endoplasmic reticulum(ER)stress and oxidative stress to impair endothelial function.The glucagon-like peptide 1(GLP-1)analog exendin-4 attenuates endothelial ER stress,but the detailed vasoprotective mechanism remains elusive.The present study investigated the beneficial effects of exendin-4 against HHcy-induced endothelial dysfunction.Exendin-4 pretreatment reversed homocysteine-induced impairment of endothelium-dependent relaxations in C57BL/6 mouse aortae ex vivo.Four weeks subcutaneous injection of exendin-4 restored the impaired endothelial function in both aortae and mesenteric arteries isolated from mice with diet-induced HHcy.Exendin-4 treatment lowered superoxide anion accumulation in the mouse aortae both ex vivo and in vivo.Exendin-4 decreased the expression of ER stress markers(e.g.,ATF4,spliced XBP1,and phosphorylated eIF2α)in human umbilical vein endothelial cells(HUVECs),and this change was reversed by cotreatment with compound C(CC)(AMPK inhibitor).Exendin-4 induced phosphorylation of AMPK and endothelial nitric oxide synthase in HUVECs and arteries.Exendin-4 increased the expression of endoplasmic reticulum oxidoreductase(ERO1α),an important ER chaperone in endothelial cells,and this effect was mediated by AMPK activation.Experiments using siRNA-mediated knockdown or adenoviral overexpression revealed that ERO1αmediated the inhibitory effects of exendin-4 on ER stress and superoxide anion production,thus ameliorating HHcy-induced endothelial dysfunction.The present results demonstrate that exendin-4 reduces HHcy-induced ER stress and improves endothelial function through AMPK-dependent ERO1αupregulation in endothelial cells and arteries.AMPK activation promotes the protein folding machinery in endothelial cells to suppress ER stress. | Chak Kwong Cheng Jiang-Yun Luo Chi Wai Lau William Chi-shing Cho Chi Fai Ng Ronald Ching Wan Ma Xiao Yu Tian Yu Huang | 2021 | Acta Pharmacologica Sinica2021，42，10： | 6 |
| 18 | A cross-sectional study on compliance with topical glaucoma medication and its associated socioeconomic burden for a Chinese population显示文摘AIM: To estimate the overall drug compliance for local Chinese glaucoma patients on long-term topical treatment.METHODS: This was a retrospective cross-sectional study.Fifty-seven primary glaucoma patients from the subspecialty clinic of a publicly-funded tertiary care hospital in Hong Kong completed a questionnaire on compliance with topical glaucoma medication,attitude towards glaucoma and therapy and vision related quality of life.Noncompliance was defined as reporting missing more than or equal to 10% of the prescribed topical glaucoma medication during the 2wk immediately prior to the consultation.Relationships between noncompliance and demographics,attitude,disease and treatment status was studied.Cost was estimated with quality of life and direct medical cost involved with noncompliance.Multivariable logistic regression on noncompliance was performed on selected factors.RESULTS: Compliance was calculated as 75%(95% CI: 64%-87%) among 57 subjects(mean age 69 y,female 51%).No statistical significant relationship was established between noncompliance and any single factors or outcomes.Age(P=0.048) and forgetfulness(P=0.064) were found to be marginally significant predictive factors on noncompliance in multivariable logistic regression.Noncompliance might be related(P=0.130) to poorer self-rated vision-associated quality of life.The societal cost of noncompliance was estimated to be over 2510 life-years and US$ 3.7 million territory-wide.CONCLUSION: The compliance of Chinese glaucoma patients in Hong Kong is comparable to other parts in the world,and carries detrimental impacts on individual and societal levels.Age and forgetfulness are two possible independent predictors for noncompliance. | Man-Hin Lui Jason Chun Ho Lam Yi Lee Kwong Tak Siu Wong Pak Long Cheung Sherri Shun Yan Lai Pak Lun Yuen Wai Yiu Lam Ho Yan Chan Yiu Fai Wong Jimmy Shiu Ming Lai Kendrick Co Shih | 2017 | International Journal of Ophthalmology(English edition)2017，10，2： | 5 |
| 19 | Profiles and removal efficiency of polycyclic aromatic hydrocarbons by two different types of sewage treatment plants in Hong Kong显示文摘Sewage discharge could be a major source of polycyclic aromatic hydrocarbons(PAHs) in the coastal waters. Stonecutters Island and Shatin Sewage Treatment Works(SCISTW and STSTW)in Hong Kong, adopted chemically enhanced primary treatment and biological treatment,respectively. This study aimed at(1) determining the removal efficiencies of PAHs,(2) comparing the capabilities in removing PAHs, and(3) characterizing the profile of each individual PAHs, in the two sewage treatment plants(STPs). Quantification of 16 PAHs was conducted by a Gas Chromatography. The concentrations of total PAHs decreased gradually along the treatment processes(from 301 ± 255 and 307 ± 217 ng/L to 14.9 ± 12.1 and 63.3 ± 54.1 ng/L in STSTW and SCISTW, respectively). It was noted that STSTW was more capable in removing total PAHs than SCISTW with average total removal efficiency 94.4% ± 4.12% vs. 79.2% ± 7.48%(p < 0.05). The removal of PAHs was probably due to sorption in particular matter, confirmed by the higher distribution coefficient of individual and total PAHs in solid samples(dewatered sludge contained92.5% and 74.7% of total PAHs in SCISTW and STSTW, respectively) than liquid samples(final effluent-total contained 7.53% and 25.3% of total PAHs in STSTW and SCISTW, respectively).Despite the impressive capability of STSTW and SCISTW in removing PAHs, there was still a considerable amount of total PAHs(1.85 and 39.3 kg/year, respectively for the two STPs) being discharged into Hong Kong coastal waters, which would be an environmental concern. | Yu Bon Man Ka Lai Chow Zhang Cheng Wing Yin Mo Yung Hau Chan James Chung Wah Lam Frankie Tat Kwong Lau Wing Cheong Fung Ming Hung Wong | 2017 | Journal of Environmental Sciences2017，29，3： | 5 |
