| 1 | 基于变分模态分解和蝙蝠算法-相关向量机的短期风速区间预测显示文摘现有的风速预测方法大多是确定性的点预测,无法描述风速的随机性。针对该问题,建立基于变分模态分解(VMD)和蝙蝠算法-相关向量机(BA-RVM)的短期风速区间预测模型。对原始风速序列进行变分模态分解获得多个子序列;采用样本熵(SE)算法对子序列进行重组得到3类具有典型特性的分量;对各分量采用相关向量机算法分别建立预测模型。为进一步提高预测精度、缩小区间范围,引入蝙蝠算法(BA)对预测模型进行参数优化。将各分量的预测结果进行叠加求和得到一定置信水平下总体的区间预测结果。实际算例结果表明,与现有方法相比,所提区间预测方法的预测精度和区间覆盖率更高,区间宽度更窄。 | 范磊 卫志农 李慧杰 Kwok W Cheung 孙国强 孙永辉 | 2017 | 电力自动化设备2017，37，1： | 44 |

| 7 | The effects of probiotics administration on the milk production,milk components and fecal bacteria microbiota of dairy cows显示文摘Probiotics administration can improve host health.This study aims to determine the effects of probiotics(Lactobacillus casei Zhang and Lactobacillus plantarum P-8) administration on milk production,milk functional components,milk composition,and fecal microbiota of dairy cows.Variations in the fecal bacteria microbiota between treatments were assessed based on 16 S rRNA profiles determined by Pac Bio single molecule real-time sequencing technology.The probiotics supplementation significantly increased the milk production and the contents of milk immunoglobulin G(IgG),lactoferrin(LTF),lysozyme(LYS)and lactoperoxidase(LP),while the somatic cell counts(SCC) significantly decreased(P < 0.01).However,no significant difference was found in the milk fat,protein and lactose contents(P > 0.05).Although the probiotics supplementation did not change the fecal bacteria richness and diversity,significantly more rumen fermentative bacteria(Bacteroides,Roseburia,Ruminococcus,Clostridium,Coprococcus and Dorea) and beneficial bacteria(Faecalibacterium prausnitzii) were found in the probiotics treatment group.Meanwhile,some opportunistic pathogens e.g.Bacillus cereus,Cronobacter sakazakii and Alkaliphilus oremlandii,were suppressed.Additionally,we found some correlations between the milk production,milk components and fecal bacteria.To sum up,our study demonstrated the beneficial effects of probiotics application in improving the quality and quantity of cow milk production. | Haiyan Xu Weiqiang Huang Qiangchuan Hou Lai-yu Kwok Zhihong Sun Huimin Ma Feiyan Zhao Yuan-Kun Lee Heping Zhang | 2017 | Science Bulletin2017，62，11： | 21 |
| 8 | Patients with Helicobacter pylori positive and negative duodenal ulcers have distinct clinical characteristics显示文摘AIM: To assess the clinical characteristics of Helicobacterpylori(H pylori) negative duodenal ulcer.METHODS: Patients with an endoscopic diagnosis of duodenal ulcer between 1996 and 2002 were included in the present study. Patients were considered to be negative for Hpylori, if both histological examination and rapid urease test of biopsy specimens were negative. A comparison was made between patients with H pyloripositive and negative duodenal ulcers.RESULTS: A total of 1 343 patients were studied. Their mean age was 54.7±0.5 years. There was a male preponderance (M:F = 2.5:1). Three hundred and ninetyeight patients (29.6%) did not have H pylori infection. The annual proportion of patients with H pylori negative duodenal ulcers increased progressively from 1996 to2002. On multivariate analysis, patients with H pylorinegative duodenal ulcer were more likely to be older, have concomitant medical problem, pre-existing malignancy, recent surgery, underlying sepsis, or taken non-steroidal anti-inflammatory drugs. In terms of clinical presentations, patients with H pylori negative duodenal ulcer were more likely to present with bleeding, multiple ulcers and larger ulcers.CONCLUSION: The proportion of patients with H pylori negative duodenal ulcers is on the rise because of a continued drop in incidence of H pylori positive duodenalulcers in recent years. Such patients have distinct clinical characteristics and it is important to ascertain the H pylori status before starting eradication therapy. | Kent-Man Chu Ka-Fai Kwok Simon Law Kam-Ho Wong | 2005 | World Journal of Gastroenterology2005，11，23： | 17 |
| 9 | Robotic surgery for rectal cancer: A systematic review of current practice显示文摘AIM: To give a comprehensive review of current litera-ture on robotic rectal cancer surgery.METHODS: A systematic review of current literature via PubMed and Embase search engines was per-formed to identify relevant articles from january 2007 to november 2013. The keywords used were: 'robotic surgery', 'surgical robotics', 'laparoscopic computer-assisted surgery', 'colectomy' and 'rectal resection'. RESULTS: After the initial screen of 380 articles, 20 pa-pers were selected for review. A total of 1062 patients(male 64.0%) with a mean age of 61.1 years and body mass index of 24.9 kg/m2 were included in the review.Out of 1062 robotic-assisted operations, 831(78.2%) anterior and low anterior resections, 132(12.4%) in-tersphincteric resection with coloanal anastomosis, 98(9.3%) abdominoperineal resections and 1(0.1%) Hart-mann's operation were included in the review. Robotic rectal surgery was associated with longer operative time but with comparable oncological results and anastomotic leak rate when compared with laparoscopic rectal surgery. CONCLUSION: Robotic colorectal surgery has con-tinued to evolve to its current state with promising re-sults; feasible surgical option with low conversion rate and comparable short-term oncological results. The challenges faced with robotic surgery are for more high quality studies to justify its cost. | Tony Wing Chung Mak Janet Fung Yee Lee Kaori Futaba Sophie Sok Fei Hon Dennis Kwok Yu Ngo Simon Siu Man Ng | 2014 | World Journal of Gastrointestinal Oncology2014，6，6： | 16 |

| 11 | A perturbation-incremental scheme for studying Hopf bifurcation in delayed differential systems显示文摘A new method, called perturbation-incremental scheme (PIS), is presented to investigate the periodic solution derived from Hopf bifurcation due to time delay in a system of first-order delayed differential equations. The method is summarized as three steps, namely linear analysis at critical value, perturba- tion and increment for continuation. The PIS can bypass and avoid the tedious calculation of the center manifold reduction (CMR) and normal form. Meanwhile, the PIS not only inherits the advantages of the method of multiple scales (MMS) but also overcomes the disadvantages of the incremental harmonic balance (IHB) method. Three delayed systems are used as illustrative examples to demonstrate the validity of the present method. The periodic solution derived from the delay-induced Hopf bifurcation is obtained in a closed form by the PIS procedure. The validity of the results is shown by their consis- tency with the numerical simulation. Furthermore, an approximate solution can be calculated in any required accuracy. | CHUNG Kwok Wai | 2009 | Science China(Technological Sciences)2009，52，3： | 15 |

| 13 | Effect of dietary interventions on the intestinal microbiota of Mongolian hosts显示文摘The gut microbiota of Mongolian hosts has distinctive characteristics due to their meat- and dairyoriented daily diets and unique genotype.The aim of the present study was to investigate the effect of switching from the typical high protein and fat Mongolian diets to carbohydrate-rich meals composed principally of wheat,rice and naked oats on the host gut microbiota within 3 weeks.Our study took the advantage of the long sequence reads produced by the Pac Bio single molecule real-time sequencing technology to enable the profiling of subjects' gut microbiota communities along the diet intervention to the species precision.We found that the bacterial richness and diversity decreased apparently along the diet intervention.During the diet intervention,the gut microbiota composition displayed no significant difference at phylum level(with major phyla of Firmicutes,Bacteroidetes,Tenericutes and Proteobacteria).The relative abundances of some genera such as Bacteroidetes,Faecalibacterium,Roseburia,Alistipes,Streptococcus,and Oscillospira were significantly altered after the diet switching started.Notably,significant changes were also observed in the proportions of the species Bacteroides dorei,Bacteroides fragilis,Bacteroides thetaiotaomicron,Ruminococcus albus,Ruminococcus faecis,Roseburia faecis and Eubacterium ventriosum.These results have demonstrated that diet and host gut microbiota is closely linked. | Jing Li Haiyan Xu Zhihong Sun Qiangchuan Hou Lai-Yu Kwok Wuri Laga Yanjie Wang Huimin Ma Zhongjie Yu Bilige Menghe Heping Zhang | 2016 | Science Bulletin2016，61，20： | 14 |
| 14 | Preliminary experience with drug-coated balloon angioplasty in primary percutaneous coronary intervention显示文摘We evaluated the clinical feasibility of using drugcoated balloon(DCB) angioplasty in patients undergoingprimary percutaneous coronary intervention(PPCI). Between January 2010 to September 2014,89 STelevation myocardial infarction patients(83% male,mean age 59 ± 14 years) with a total of 89 coronary lesions were treated with DCB during PPCI. Clinical outcomes are reported at 30 d follow-up. Left anterior descending artery was the most common target vessel for PCI(37%). Twenty-eight percent of the patients had underlying diabetes mellitus. Mean left ventricular ejection fraction was 44% ± 11%. DCB-only PCI was the predominant approach(96%) with the remaining 4% of patients receiving bail-out stenting. Thrombolysis in Myocardial Infarction(TIMI) 3 flow was successfully restored in 98% of patients. An average of 1.2 ± 0.5 DCB were used per patient,with mean DCB diameter of 2.6 ± 0.5 mm and average length of 23.2 ± 10.2 mm. At 30-d follow-up,there were 4 deaths(4.5%). No patients experienced abrupt closure of the infarctrelated artery and there was no reported target-lesion failure. Our preliminary experience showed that DCB angioplasty in PPCI was feasible and associated with a high rate of TIMI 3 flow and low 30-d ischaemic event. | Hee Hwa Ho Julian Tan Yau Wei Ooi Kwok Kong Loh Than Htike Aung Nwe Tun Yin Dasdo Antonius Sinaga Fahim Haider Jafary Paul Jau Lueng Ong | 2015 | World Journal of Cardiology2015，7，6： | 14 |
| 15 | 尖锐心肌的梗塞: 在在新加坡的年轻成年人的临床的特征和结果显示文摘 AIM: To investigate the clinical features and in-hospital outcomes of young adults with acute myocardial infarction (AMI) in Singapore. METHODS: Between January 2005 to September 2010, 333 consecutive patients aged ≤ 45 years old were diagnosed to have AMI at our institution. As Singapore is a multi-ethnic society, we also analysed whether ethnic differences exist between the three dominant ethnic groups, Malay, Chinese and Indian with regards to the clinical features. Clinical data was collected retrospectively on demographic characteristics, presenting signs and symptoms, blood investigation, angiographic findings and in-hospital clinical outcomes. RESULTS: The mean age at presentation was 40.2 ± 4.0 years with male predominance (94%). The majority of patients were Chinese (51%) followed by Indians (31%) and Malays (18%). The most common risk factor was smoking (74%) followed by hypertension (28.5%) and hyperlipidemia (20.0%). 37% of patients were obese. The majority of patients had single vessel disease (46%) on coronary angiography. The mean total cholesterol, low-density lipoprotein and highdensity lipoprotein levels were 5.6±1.2 mmol/L, 3.8±1.1 mmol/L and 0.93±0.25 mmol/L respectively. The mean left ventricular function was 44%±10% with the incidence of heart failure 3% and cardiogenic shock 4.5%. Overall in-hospital mortality was low with 4 deaths (1.2%). For ethnic subgroup analysis, Indians have a 3-fold risk of developing premature AMI when compared to other ethnic groups. CONCLUSION: Young AMI patients in Singapore are characterized by male predominance, high incidence of smoking and obesity. Overall in-hospital clinical outcomes are favourable. Among the 3 ethnic groups, Indians have the highest risk of developing premature AMI. | Chun Pong Wong Seet Yoong Loh Kwok Kong Loh Paul Jau Lueng Ong David Foo Hee Hwa Ho | 2012 | World Journal of Cardiology2012，4，6： | 13 |

| 17 | The interplay of host genetic factors and Epstein-Barr virus in the development of nasopharyngeal carcinoma显示文摘The interplay between host cell genetics and Epstein-Barr virus(EBV) infection contributes to the development of nasopharyngeal carcinoma(NPC). Understanding the host genetic and epigenetic alterations and the influence of EBV on cell signaling and host gene regulation will aid in understanding the molecular pathogenesis of NPC and provide useful biomarkers and targets for diagnosis and therapy. In this review, we provide an update of the oncogenes and tumor suppressor genes associated with NPC, as well as genes associated with NPC risk including those involved in carcinogen detoxification and DNA repair. We also describe the importance of host genetics that govern the human leukocyte antigen(HLA) complex and immune responses, and we describe the impact of EBV infection on host cell signaling changes and epigenetic regulation of gene expression. High-power genomic sequencing approaches are needed to elucidate the genetic basis for inherited susceptibility to NPC and to identify the genes and pathways driving its molecular pathogenesis. | Maria Li Lung Arthur Kwok Leung Cheung Josephine Mun Yee Ko Hong Lok Lung Yue Cheng Wei Dai | 2014 | Chinese Journal of Cancer2014，33，11： | 13 |
