2Epidemiology of clinical benign prostatic hyperplasia显示文摘Clinical benign prostatic hyperplasia(BPH)is one of the most common diseases in ageing men and the most common cause of lower urinary tract symptoms(LUTS).The prevalence of BPH increases after the age of 40 years,with a prevalence of 8%-60% at age 90 years.Some data have suggested that there is decreased risk among the Asians compared to the western white population.Genetics,diet and life style may play a role here.Recent reports suggest the strong relationship of clinical BPH with metabolic syndrome and erectile dysfunction,as well as the possible role of inflammation as a cause of the prostatic hyperplasia.Lifestyle changes including exercise and diet are important strategies in controlling this common ailment.Kok Bin Lim 2017Asian Journal of Urology2017,4,3:26
3Current research and treatment for gastrointestinal stromal tumors显示文摘Gastrointestinal stromal tumors(GISTs) are the most common mesenchymal tumors of the gastrointestinal tract and have gained considerable research and treatment interest,especially in the last two decades. GISTs are driven by mutations commonly found in the KIT gene and less commonly in the platelet-derived growth factor receptor alpha gene,BRAF gene and succinate dehydrogenase gene. GISTs behave in a spectrum of malignant potential,and both the tumor size and mitotic index are the most commonly used prognostic criteria. Whilst surgical resection can offer the best cure,targeted therapy in the form of tyrosine kinase inhibitors(TKIs) has revolutionized the management options. As the first-line TKI,imatinib offers treatment for advanced and metastatic GISTs,adjuvant therapy in high-risk GISTs and as a neoadjuvant agent to downsize large tumors prior to resection. The emergence of drug resistance has altered some treatment options,including prolonging the first-line TKI from 1 to 3 years,increasing the dose of TKI or switching to second-line TKI. Other newer TKIs,such as sunitinib and regorafenib,may offer some treatment options for imatinib-resistant GISTs. New molecular targeted therapies are being evaluated,such as inhibitors of BRAF,heat shock protein 90,glutamine and mitogenactivated protein kinase signaling,as well as inhibitors of apoptosis proteins antagonist and even immunotherapy. This editorial review summarizes the recent research trials and potential treatment targets that may influence our future patient-specific management of GISTs. The current guidelines in GIST management from Europe,North America and Asia are highlighted.Kheng Tian Lim Kok Yang Tan 2017World Journal of Gastroenterology2017,23,27:23

5Suppression of innate antiviral response by severe acute respiratory syndrome coronavirus M protein is mediated through the first transmembrane domain显示文摘Coronaviruses 开发了各种各样的措施躲避天生的免疫。我们以前证明了那严重急性呼吸症候群(SARS ) coronavirus M 蛋白质压制类型我由阻碍功能的包含 TRAF3 的形成的干扰素(IFN ) 生产复杂。在这研究,我们证明反对 IFN 活动对 SARS coronavirus M 蛋白质特定并且通过它在 N 终点定位的第一个 transmembrane 领域(TM1 ) 被调停。从人的 coronavirus HKU1 的 M 蛋白质不禁止 IFN 生产。而 SARS coronavirus M 蛋白质的连接 N 的 glycosylation 没在 IFN 对抗上有影响, TM1 为 IFN 生产的抑制是不可缺少的。TM1 目标 SARS coronavirus M 蛋白质和 heterologous 蛋白质到 Golgi 仪器,然而, Golgi 本地化被要求然而并非为 IFN 足够对抗。机械学地, TM1 能够有 RIG-I, TRAF3, TBK1 和 IKKε 的绑定;,并且与它的下游的受动器阻止 TRAF3 的相互作用。我们的工作定义为天生的抗病毒的反应的抑制要求的 SARS coronavirus M 蛋白质的分子的建筑学。Kam-Leung Siu Chi-Ping Chan Kin-Hang Kok Patrick Chiu-Yat Woo Dong-Yan Jin 2014Cellular & Molecular Immunology2014,11,2:13
6Therapeutic and prevention strategies against human enterovirus 71 infection显示文摘Human enterovirus 71(HEV71) is the cause of hand,foot and mouth disease and associated neurological complications in children under five years of age.There has been an increase in HEV71 epidemic activity throughout the Asia-Pacific region in the past decade,and it is predicted to replace poliovirus as the extant neurotropic enterovirus of highest global public health significance. To date there is no effective antiviral treatment and no vaccine is available to prevent HEV71 infection. The increase in prevalence, virulence and geographic spread of HEV71 infection over the past decade provides increasing incentive for the development of new therapeutic and prevention strategies against this emerging viral infection. The current review focuses on the potential, advantages and disadvantages of these strategies. Since the explosion of outbreaks leading to large epidemics in China, research in natural therapeutic products has identified several groups of compounds with anti-HEV71 activities. Concurrently, the search for effective synthetic antivirals has produced promising results. Other therapeutic strategies including immunotherapy and the use of oligonucleotides have also been explored. A sound prevention strategy is crucial in order to control the spread of HEV71. To this end the ultimate goal is the rapid development, regulatory approval and widespread implementation of a safe and effective vaccine. The various forms of HEV71 vaccine designs are highlighted in this review. Given the rapid progress of research in this area, eradication of the virus is likely to be achieved.Chee Choy Kok 2015World Journal of Virology2015,4,2:12
7Report on Childhood Obesity in China (5) Body Weight, Body Dissatisfaction, and Depression Symptoms of Chinese Children Aged 9-10 Years显示文摘Objective To investigate the relationship between body weight, body dissatisfaction and depression symptoms among Chinese children. Methods The fasting body weight and height of the third and fourth grade students (n=3886, aged 9 or 10 years) from 20 schools in Beijing, China, were measured, and the students were asked to choose the figures of body image and to complete the self-reported children’s depression inventory (CDI) questionnaire. Results The CDI Cronbach’s alpha was 0.81. The total CDI score was 9.60±7.50, 13.2% of children (boys 16.7% vs girls 9.5%) were at risk of developing depression symptoms. Overweight girls, but not boys, had significantly higher total CDI score than their normal weight counteparts. Both obese girls and boys showed a higher negative self-esteem score. More than one fifth underweight girls still wanted to be thinner while more than one third obese boys still wanted to be heavier. Children who wanted to be thinner showed slightly higher scores of ineffectiveness and negative self-esteem. After introducing the body dissatisfaction into the model, overweight was still associated with total CDI score among girls and obesity was still associated with negative self-esteem among both boys and girls. Conclusion Overweight girls show a significantly higher depression symptom score than their normal weight counterparts, which maybe partially explained by body dissatisfaction. Obese boys and girls are both more likely to suffer from low self-esteem, which is partially explained by body dissatisfaction.YAN-PING LI GUAN-SHENG MA EVERT G.

11Intrahepatic vascular changes in non-alcoholic fatty liver disease: potential role of insulin-resistance and endothelial dysfunction显示文摘Metabolic syndrome is a cluster of several clinical conditions characterized by insulin-resistance and high cardiovascular risk. Non-alcoholic fatty liver disease is the liver expression of the metabolic syndrome, and insulin resistance can be a frequent comorbidity in several chronic liver diseases, in particular hepatitis C virus infection and/or cirrhosis. Several studies have demonstrated that insulin action is not only relevant for glucose control, but also for vascular homeostasis. Insulin regulates nitric oxide production, which mediates to a large degree the vasodilating, antiinflammatory and antithrombotic properties of a healthy endothelium, guaranteeing organ perfusion. The effects of insulin on the liver microvasculature and the effects of IR on sinusoidal endothelial cells have been studied in animal models of non-alcoholic fatty liver disease. The hypotheses derived from these studies and the potential translation of these results into humans are critically discussed in this review.Marcos Pasarín Juan G Abraldes Eleonora Liguori Beverley Kok Vincenzo La Mura 2017World Journal of Gastroenterology2017,23,37:6
12IVF或ICSI周期卵巢过度刺激获取大量卵子并不会导致妊娠率降低显示文摘Objective: To investigate the possible negative effects of a strong ovarian response on oocyte quality.Design: Retrospective study.Setting: Tertiary academic center.Patient(s): A total of 1, 894 women (IVF, n = 1, 544; ICSI, n = 350) who underwent their first ovarian stimulation cycle during the period 1995- 2002.Intervention(s): Standardized controlled ovarian stimulation with urinary FSH or recombinant FSH after pituitary down- regulation, followed by IVF/intracytoplasmic sperm injection (ICSI) and ET.Main Outcome Measure(s): Fertilization rate, fraction of high- quality embryos, and implantation rate.Result(s): Using multivariate logistic regression, we analyzed the effect, expressed as an odds ratio (OR), of the number of oocytes obtained (i.e., ovarian response) on the outcome measures.No effect of the response on the ongoing implantation rate or fraction of high- quality embryos was observed.Both in IVF (OR = 0.81, 95% confidence interval [CI] 0.75- 0.87) and in ICSI (OR = 0.88, 95% CI 0.76- 1.00), a negative effect of increasing ovarian response was seen on the fertilization rate per oocyte obtained.However, no negative effect was observed on the fertilization rate per oocyte injected in ICSI (OR = 1.00, 95% CI 0.87- 1.14).The fraction of immature oocytes rises from 3.9% , in women with ≤ 3 oocytes, to 26% in women with > 20 oocytes.Conclusion(s): Oocytes from high responders contain a greater fraction of immature oocytes, but pregnancy outcome is not impaired.Kok J.D.

14Cerebrospinal fluid phosphorylated tau,visinin-like protein-1,and chitinase-3-like protein 1 in mild cognitive impairment and Alzheimer’s disease显示文摘Background:Visinin-like protein-1(VILIP-1)and chitinase-3-like protein 1(CHI3L1 or YKL-40)in cerebrospinal fluid(CSF)are newly discovered markers indicating neuronal damage and microglial activation,respectively.Phosphorylated tau(p-tau)reflects the neuropathology of Alzheimer’s disease(AD)and is useful as diagnostic markers for AD.However,it is unknown whether these biomarkers have similar or complementary information in AD.Methods:We stratified 121 participants from the Alzheimer’s Disease Neuroimaging Initiative(ADNI)database into cognitively normal(CN),stable mild cognitive impairment(sMCI),progressive MCI(pMCI),and dementia due to AD.Analysis of covariance(ANOVA)and chi-square analyses,Spearman correlation,and logistic regression models were performed to test the demographic,associations between biomarkers,and diagnostic accuracies,respectively.Linear mixed-effects models were used to evaluate the effects of CSF amyloid-β(Aβ)on above biomarkers within diagnostic groups,the combination of diagnostic group and Aβstatus as predictor,and CSF biomarkers as predictors of AD features,including cognition measured by Mini–Mental State Examination(MMSE)and brain structure and white matter hyperintensity(WMH)measured by magnetic resonance imaging(MRI).Results:P-tau,VILIP-1,and YKL-40 were all predictors of AD diagnosis,but combinations of biomarkers did not improve the diagnostic accuracy(AUC 0.924 for p-tau,VILIP-1,and YKL-40)compared to p-tau(AUC 0.922).P-tau and VILIP-1 were highly correlated(r=0.639,p<0.001)and strongly associated with Aβpathology across clinical stages of AD,while YKL-40 was correlated with Aβpathology in CN and AD groups.VILIP-1 was associated with acceleration of cognitive decline,hippocampal atrophy,and expansion of ventricles in longitudinal analyses.YKL-40 was associated with hippocampal atrophy at baseline and follow-up,while p-tau was only associated with worsening WMH at baseline.Conclusions:CSF levels of p-tau,VILIP-1,and YKL-40 may have utility for discriminating between cognitively normal subjects and patients with AD.Increased levels of both VILIP-1 and YKL-40 may be associated with disease degeneration.These CSF biomarkers should be considered for future assessment in the characterization of the natural history of AD.Hua Zhang Kok Pin Ng Joseph Therriault Min Su Kang Tharick APascoal Pedro Rosa-Neto Serge Gauthier the Alzheimer’s Disease Neuroimaging Initiative 2018Translational Neurodegeneration2018,7,1:5
15HIV/AIDS in Asia:The Shape of Epidemics and Their Molecular Epidemiology显示文摘The Asia-Pacific region is a home to 60% of the population in the world and to approximately one quarter of people with HIV/AIDS. Close to a million of people has been infected and a half million people died of AIDS annually in Asia,becoming the second largest epicenter of global AIDS epidemic. Molecular epidemiology has been useful tool to track a course of HIV spread. In-depth knowledge from the studies on molecular epidemiology elucidates the dynamics of HIV spread and the interrelationship of epidemics in the different regions in Asia.Rie Uenishi Saiki Hase Tee Kok Keng Shigeru Kusagawa Yutaka Takebe 2007Virologica Sinica2007,22,6:4
16Can intravesical prostatic protrusion predict bladder outlet obstruction even in men with good flow?显示文摘Objective:Men with benign prostate hyperplasia(BPH)with good urinary flow may still have bladder outlet obstruction(BOO).Intravesical prostatic protrusion(IPP)has been shown to be able to predict BOO.We aim to investigate the use of IPP to predict BOO in men with good urinary flow.Methods:One hundred and fourteen consecutive men(>50 years old)presenting with lower urinary tract symptoms suggestive of BPH were recruited in 2001 and 2002.They were evaluated with serum prostate specific antigen(PSA),uroflowmetry and transabdominal ultrasound measurement of IPP and prostate volume(PV).Pressure-flow urodynamic studies were performed on all men and BOO was defined by BOO index>40.Men with Qmax12.0 mL/s were considered to have good flow.Results:Among the 114 men,61 patients had good urinary flow.Their median age,PV and Qmax were 66 years,32.9 mm3 and 14.5 mL/s respectively.14/61(23.0%)patients had BOO and their distribution of IPP were as follows:Grade 1 e 0/20(0%)obstructed,Grade 2 e 6/22(27.3%)and Grade 3 e 8/19(42.1%).Sensitivity of Grade 2/3 IPP for BOO was 100% while specificity of Grade 3 IPP was 76.6%.The area-under-curve(AUC)for IPP was greater than that for PV(0.757 vs.0.696).Conclusion:Even in men with good flow,high grades of IPP were more likely to have BOO and hence,may be a useful adjunct to predict BOO.Alvin Lee Han Jie Lee Kok Bin Lim Hong Hong Huang Henry Ho Keong Tatt Foo 2016Asian Journal of Urology2016,3,1:4
17Reducing risk of transjugular intrahepatic portosystemic shunt using ultrasound guided single needle pass显示文摘Delayed liver laceration following transjugular intrahepatic portosystemic shunt (TIPS) is a serious and likely underdiagnosed complication. It is however an important complication following TIPS, which remains one of the most technically challenging interventional procedures performed. In addition to laceration, a number of complications regarding bleeding and perforation are well described following TIPS procedures. We feel the adoption of techniques such as ours and that of other authors described in the literature using an ultrasoundguided percutaneous transhepatic approach with a small caliber needle provides a safer and less traumatic procedure and should reduce complications of bleeding and almost completely eliminate the risk of liver laceration. Our procedure was successfully performed under conscious sedation rather than general anaesthesia further reducing the overall procedural risk to the patient.Sum Leong Hong Kuan Kok Pradeep Govender William Torreggiani 2013World Journal of Gastroenterology2013,19,22:4
18A Dual-driven Intelligent Combination Control of Heat Pipe Space Cooling System显示文摘Effective thermal control systems are essential for reliable operation of spacecraft.A dual-driven intelligent combination control strategy is proposed to improve the temperate control and heat flux tracking effects.Both temperature regulation and heat flux tracking errors are employed to generate the final control action;their contributions are adaptively adjusted by a fuzzy fusing policy of control actions.To evaluate the control effects,describe a four-nodal mathematical model for analyzing the dynamic characteristics of the controlled heat pipe space cooling system(HP-SCS) consisting of an aluminum-ammonia heat pipe and a variable-emittance micro-electromechanical-system(MEMS) radiator.This dynamical model calculates the mass flow-rate and condensing pressure of the heat pipe working fluid directly from the systemic nodal temperatures,therefore,it is more suitable for control engineering applications.The closed-loop transient performances of four different control schemes have been numerically investigated.The results conclude that the proposed intelligent combination control scheme not only improves the thermal control effects but also benefits the safe operation of HP-SCS.LI Yunze LI Mingmin LEE Kok Meng 2012Chinese Journal of Aeronautics2012,25,4:4

20Viral respiratory infections among Hajj pilgrims in 2013显示文摘Middle East respiratory syndrome coronavirus(MERS-Co V) has emerged in the Arabian Gulf region, with its epicentre in Saudi Arabia, the host of the ‘Hajj' which is the world's the largest mass gathering. Transmission of MERS-Co V at such an event could lead to its rapid worldwide dissemination. Therefore, we studied the frequency of viruses causing influenza-like illnesses(ILI) among participants in a randomised controlled trial at the Hajj 2013. We recruited 1038 pilgrims from Saudi Arabia, Australia and Qatar during the first day of Hajj and followed them closely for four days. A nasal swab was collected from each pilgrim who developed ILI. Respiratory viruses were detected using multiplex RT-PCR. ILI occurred in 112/1038(11%) pilgrims. Their mean age was 35 years, 49(44%) were male and 35(31%) had received the influenza vaccine pre-Hajj. Forty two(38%) pilgrims had laboratory-confirmed viral infections; 28(25%) rhinovirus, 5(4%) influenza A, 2(2%) adenovirus, 2(2%) human coronavirus OC43/229 E, 2(2%) parainfluenza virus 3, 1(1%) parainfluenza virus 1, and 2(2%) dual infections. No MERS-Co V was detected in any sample. Rhinovirus was the commonest cause of ILI among Hajj pilgrims in 2013. Infection control and appropriate vaccination are necessary to prevent transmission of respiratory viruses at Hajj and other mass gatherings.Osamah Barasheed Harunor Rashid Mohammad Alfelali Mohamed Tashani Mohammad Azeem Hamid Bokhary Nadeen Kalantan Jamil Samkari Leon Heron Jen Kok Janette Taylor Haitham El Bashir Ziad A.Memish Elizabeth Haworth Edward C.Holmes Dominic E Dwyer Atif Asghar Robert Booy 2014Virologica Sinica2014,29,6:3
