1中国农村合作医疗的受益公平性显示文摘在中国的大多数地区所建立的合作医疗都属于“低保费、高共付率”的形式。虽然低保费更有利于贫困的农民参加合作医疗,但是,高共付率会阻碍他们实际利用医疗服务。利用2002年中国贵州省开阳县冯三镇的家庭入户调查资料,采用logistic回归模型和“四部模型”研究农民参加合作医疗的概率、合作医疗参加者对卫生服务的利用、以及农民从合作医疗获得的净收益,探索这种“低保费、高共付率”设计的合作医疗的受益公平性。结果表明,在“低保费、高共付率”模式下,合作医疗受益存在着不公平性。基于研究结果提出了政策性建议。汪宏 Winnie Yip 张里程 王禄生 萧庆伦 2005中国卫生经济2005,24,2:70
2APACHE system is better than Ranson system in the prediction of severity of acute pancreatitis显示文摘BACKGROUND: It has been suggested that addition of obesity score to the APACHE-Ⅱ system can lead to more accurate prediction of severity of acute pancreatitis. However there is scanty information on the usefulness of the combined APACHE-O scoring system in Asian patients. This study aimed to compare the accuracy of Ranson, APACHE-Ⅱ and APACHE-O systems in assessing severity of acute pancreatitis in a local Chinese population. METHODS: One hundred and one consecutive patients with acute pancreatitis were prospectively studied. Body mass index (BMI) was measured on admission. Ranson score, APACHE-Ⅱ and APACHE-O scores were recorded on admission and at 48 hours. By adopting the cut-off levels and definitions advocated in the Atlanta consensus for severe disease, the diagnostic accuracy of the three scoring systems was compared by the area under the curve (AUC) under the receiver operator characteristic curve. RESULTS: Of the 101 patients, 12 (11.9%) patients suffered from severe pancreatitis. Obesity was uncommon and only two patients (2.0%) had BMI >30. Eighty-two (81.2%) patients were normal weight (BMI≤25) whereas 17 (16.8%) were overweight ( BMI 25-30 ). Overweight or obesity (BMI >25) was not associated with severe pancreatitis (P= 0.40). The AUC for admission scores of Ranson, APACHE-Ⅱ, and APACHE-O systems was 0. 549, 0. 904 and 0. 904, respectively. The AUC for 48-hour scores of Ranson, APACHE-Ⅱ and APACHE-O systems was 0.808, 0.955 and 0.951, respectively. CONCLUSIONS: The APACHE-Ⅱ scoring system is more accurate than the Ranson scoring system of the prediction of severity in acute pancreatitis. Addition of obesity score does not significantly improve the predictive accuracy of the APACHE-Ⅱ system in our local population with a low prevalence of obesity.Yuk Pang Yeung Billy Yeung Kit Lam Andrew Wai Chun Yip 2006Hepatobiliary & Pancreatic Diseases International2006,5,2:41
3香港华人妇女产后抑郁危险因素的前瞻性研究显示文摘目的:产后抑郁是一种常见的精神障碍,对产妇、新生儿和其它家庭成员导致广泛的伤害。产后抑郁的病因学研究大多是基于西方样本,对其中的社会文化原因也缺乏实证研究。本研究从人口学、心理社会及种族文化因素等方面探讨中国妇女产后抑郁症状学的决定因素。方法:在大学附属综合医院产前门诊连续收集登记的中国孕妇959例,从她们第一次产前检查开始评估(基线),以后分别在孕期的最后3个月、产后即刻和产后3个月时评估。调查涉及的危险因素分6个方面:人口学和社会经济背景,躯体疾病及精神疾病病史, 产前抑郁情绪,围生期应激源,人际关系,和种族文化环境。采用等级回归进行分析。因变量是产后3个月时的抑郁评分。结果:决定产后抑郁症状学的因素有:目前的生活事件,缺乏社会支持,婚姻不满意,既往有故意自伤史,以及产前存在抑郁情绪。婆媳关系不好和没有陪月在产后阶段也与抑郁评分高有关联。结论:西方研究所确立的产后抑郁危险因素大体适用于中国妇女。产褥期的社会文化特点同样对产妇情绪有影响。Dominic TS Lee Alexander SK Yip Sandra SM Chan Fiona FY Lee Tony YS Leung Tony KH Chung 2005中国心理卫生杂志2005,19,9:50
4Incidence and mortality of female breast cancer in the AsiaPacific region显示文摘Objective: To provide an overview of the incidence and mortality of female breast cancer for countries in the Asia-Pacific region.Methods: Statistical information about breast cancer was obtained from publicly available cancer registry and mortality databases(such as GLOBOCAN), and supplemented with data requested from individual cancer registries. Rates were directly age-standardised to the Segi World Standard population and trends were analysed using joinpoint models.Results: Breast cancer was the most common type of cancer among females in the region, accounting for 18% of all cases in 2012, and was the fourth most common cause of cancer-related deaths(9%). Although incidence rates remain much higher in New Zealand and Australia, rapid rises in recent years were observed in several Asian countries. Large increases in breast cancer mortality rates also occurred in many areas, particularly Malaysia and Thailand, in contrast to stabilising trends in Hong Kong and Singapore, while decreases have been recorded in Australia and New Zealand. Mortality trends tended to be more favourable for women aged under 50 compared to those who were 50 years or older. Conclusion: It is anticipated that incidence rates of breast cancer in developing countries throughout the Asia-Pacific region will continue to increase. Early detection and access to optimal treatment are the keys to reducing breast cancerrelated mortality, but cultural and economic obstacles persist. Consequently, the challenge is to customise breast cancer control initiatives to the particular needs of each country to ensure the best possible outcomes.Danny R.Youlden Susanna M.Cramb Cheng Har Yip Peter D.Baade 2014Cancer Biology & Medicine2014,11,2:35

10Hepatocellular carcinoma in central Sydney :a 10yearreview of patients seen in a medical oncology department显示文摘AIM To report a single Australian oncology unit′s experience with the management of patients with hepatocellular carcinoma (HCC), in the context of a literature review of the current management issues. METHODS Retrospective case record review of 76 patients with diagnosis of HCC referred to the unit between 1984 and 1995. RESULTS Sixty three patients had adequate records for analysis. Thirty six (56%) were migrants with half from Southeast Asia. Twenty four patients had a documented viral aetiology. Nine (14%) of 51 patients with pathological confirmation of HCC had normal alpha fetoprotein levels. Median survival of the 20 patients managed palliatively was 5 weeks compared to 16 weeks for the cohort overall. Surgery in 16 patients rendered all initially disease free with a median survival of 88 weeks. Chemoembolisation induced tumor responses in 5 of the 11 patients so treated. Systemic chemotherapy and tamoxifen treatment caused tumor response in two of 12 and one of 25 respectively. CONCLUSION Prolonged survival of patients with HCC depends on early detection of small tumors suitable for surgical resection. Other active treatments are palliative in intent and have limited success. In addition to tumor response and survival duration, the toxicities of therapies and the overall quality of life of patients need to be considered as important outcomes. Viral hepatitis prevention and screening of individuals at risk are strategies that are important for HCC management in communities where the disease is endemic.Desmond Yip 1, Michael Findlay 2, Michael Boyer 1 and Martin H.

13Pathological mechanisms and therapeutic strategies for Alzheimer's disease显示文摘Alzheimer's disease is a rather complex neurodegenerative disease,which is attributed to a combination of multiple factors.Among the many pathological pathways,synaptic dysfunctions,such as synapses loss and deficits in synaptic plasticity,were thought to be strongly associated with cognitive decline.The deficiencies in various sorts of neurotransmissions are responsible for the multifarious neurodegenerative symptoms in Alzheimer's disease,for example,the cholinergic and glutamatergic deficits for cognitive decline,the excitatory and inhibitory neurotransmission dyshomeostasis for synaptic plasticity deficits and epileptiform symptoms,and the monoamine neurotransmission for neuropsychiatric symptoms.Amyloid cascade hypothesis is the most popular pathological theory to explain Alzheimer's disease pathogenesis and attracts considerable attention.Multiple lines of genetic and pathological evidence support the predominant role of amyloid beta in Alzheimer's disease pathology.Neurofibrillary tangles assembled by microtubule-associated protein tau are other important histopathological characteristics in Alzheimer's disease brains.Cascade of tau toxicity was proved to lead to neuron damage,neuroinflammation and oxidative stress in brain.Ageing is the main risk factor of neurodegenerative diseases,and is associated with inflammation,oxidative stress,reduced metabolism,endocrine insufficiencies and organ failures.These aging related risk factors were also proved to be some of the risk factors contributing to Alzheimer's disease.In Alzheimer's disease drug development,many good therapeutic strategies have been investigated in clinical evaluations.However,complex mechanism of Alzheimer's disease and the interplay among different pathological factors call for the come out of allpowerful therapies with multiple curing functions.This review seeks to summarize some of the representative treatments targeting different pathological pathways currently under clinical evaluations.Multi-target therapies as an emerging strategy for Alzheimer's disease treatment will be highlighted.Yaojun Ju Kin Yip Tam 2022Neural Regeneration Research2022,17,3:16
14UDP-glucose pyrophosphorylase2 (OsUgp2), a pollen-preferential gene in rice, plays a critical role in starch accumulation during pollen maturation显示文摘UDP-glucose pyrophosphorylase (UGPase) is predominantly present and plays significant role in carbohydrate metabolism in plants. Two homologous UGPase genes, OsUgp1 and OsUgp2, exist in rice genome. OsUgp1 has recently been reported to be essential for callose deposition during pollen mother cell and meiosis stages as well as for seed carbohydrate metabolism. In this study, a full-length cDNA of OsUgp2 was isolated from rice anther. Northern blot and RNA in situ hybridization indicated that the expression of OsUgp2 was preferentially in pollen and developmentally regulated. No transcripts were found in leaf, stem, lemma/palea, ripening grain and florets before the uninucleate microspore developmental stage, but a large quantity of OsUgp2 mRNA was found in pollen at the binucleate and mature stages. The immunolocalization of OsUgp2 showed a similar expression pattern to that by RNA in situ hybridization. The function of OsUgp2 was investigated by dsRNA-mediated transcriptional gene silencing. The pollen fertility of 16 independent transgenic rice plants was found between 25% and 90%, which was correlated with the amount of OsUgp2 mRNA. The results of morphological changes and starch variation during pollen development in transgenic rice showed that the abnormal feature of pollen development appeared after the uninucleate microspore stage. Starch failed to accumulate in pollen and thus led to sterile pollens. These results demonstrated that OsUgp2 is a pollen-preferential 'late gene' and plays a key role during pollen maturation, especially for starch accumulation. OsUgp2 complements OsUgp1 to fulfill the UGPase’s functions necessary for the full process of pollen development.MU Hong KE JianHao LIU Wei ZHUANG ChuXiong YIP WingKin 2009Chinese Science Bulletin2009,54,2:15

17Synthesis of an AIE-active fluorogen and its application in cell imaging显示文摘A fluorogen named 1-decyl-1-methyl-2,5-bis{4-[(N,N-diethylamino)methyl]phenyl}-3,4-diphenylsilole (3) was synthesized. It emitted weakly as isolated molecule but strongly as supramolecular aggregate, showing a characteristic behavior of aggregation-induced emission (AIE). The molecules of 3 formed highly emissive nanoparticles in aqueous media, which quickly and selectively marked cytoplasm of HeLa cells and posed no toxicity to the living cells. The fluorogen is thus a promising candidate mate-rial for cell imaging as a sensitive, selective and cytocompatible biosensor.LAM Jacky Wing Yip FAISAL Mahtab NG Ka Ming LUO Kathy Qian 2009Science China Chemistry2009,52,1:12
