| 1 | Epac2-deficiency leads to more severe retinal swelling, glial reactivity and oxidative stress in transient middle cerebral artery occlusion induced ischemic retinopathy显示文摘Ischemia occurs in diabetic retinopathy with neuronal loss, edema, glial cell reactivity and oxidative stress. Epacs, consisting of Epac1 and Epac2, are c AMP mediators playing important roles in maintenance of endothelial barrier and neuronal functions. To investigate the roles of Epacs in the pathogenesis of ischemic retinopathy, transient middle cerebral artery occlusion(t MCAO) was performed on Epac1-deficient(Epac1-/-) mice, Epac2-deficient(Epac2-/-) mice, and their wild type counterparts(Epac1+/+ and Epac2+/+). Two-hour occlusion and 22-hour reperfusion were conducted to induce ischemia/reperfusion injury to the retina. After t MCAO, the contralateral retinae displayed similar morphology between different genotypes. Neuronal loss, retinal edema and increase in immunoreactivity for aquaporin 4(AQP4), glial fibrillary acidic protein(GFAP), peroxiredoxin 6(Prx6) were observed in ipsilateral retinae. Epac2-/- ipsilateral retinae showed more neuronal loss in retinal ganglion cell layer, increased retinal thickness and stronger immunostaining of AQP4, GFAP, and Prx6 than those of Epac2+/+. However, Epac1-/- ipsilateral retinae displayed similar pathology as those in Epac1+/+ mice. Our observations suggest that Epac2-deficiency led to more severe ischemic retinopathy after retinal ischemia/reperfusion injury. | LIU Jin YEUNG Patrick Ka Kit CHENG Lu LO Amy Cheuk Yin CHUNG Stephen Sum Man CHUNG Sookja Kim | 2015 | Science China(Life Sciences)2015，58，6： | 12 |

| 3 | Would integrated Western and traditional Chinese medicine have more benefits for stroke rehabilitation? A systematic review and meta-analysis显示文摘Background Stroke is a major cause of death or long-term disability worldwide.Many patients with stroke receive integrative therapy consisting of Western medicine(WM)and routine rehabilitation in conjunction with Chinese medicine(CM),such as acupuncture and Chinese herbal medicine.However,there is no available evidence on the effectiveness of the combined use of WM and CM interventions in stroke rehabilitation.Aims The purpose of this meta-analysis is to evaluate the results of all individual studies to assess the combined use of CM and WM in stroke rehabilitation compared with WM only.Methods The Preferred Reporting Items for Systematic Reviews and Meta-Analysis guidelines were followed.MEDLINE,EMBASE,Cochrane and China National Knowledge Infrastructure(CNKI)were searched.The included outcomes were dependency,motor function,depression and swallowing function.Subgroup analysis was performed,and publication bias was assessed using funnel plots.Summary of review 58 studies and 6339 patients were included in the meta-analysis.Subgroup analysis revealed that combined therapy comprising both acupuncture and WM had a superior effect on improving dependency and swallowing function compared with standard WM therapy alone.Potential superiority of combined therapy comprising CM and WM in improving depression compared with standard WM therapy was also found.Conclusions Our results indicate that the combined use of CM and WM could be more efficacious in stroke rehabilitation compared with the use of WM therapy alone.However,most studies were short in duration(2 to 4 weeks)and prone to different types of biases,which prevents making any conclusion regarding the long-term effects and raises concerns regarding true efficacy in context of high likelihood of Hawthorn bias.So,more randomised controlled trials with more rigorous design and longer duration of treatment and follow-up need to be conducted to compare WM alone versus WM and CM combined. | Linda LD Zhong Ya Zheng Alexander Y Lau Norman Wong Liang Yao Xingyao Wu Tengteng Shao Zhenxing Lu Huijuan Li Chun Sum Yuen Jianwen Guo Suzanne Lo Janita Chau Kam Wa Chan Bacon Fung Leung Ng Zhaoxiang Bian Edwin Chau-leung Yu | 2022 | Stroke & Vascular Neurology2022，7，1： | 7 |
| 4 | Contents of four active components in different commercial crude drugs and preparations of Danshen (Salvia miltiorrhiza)显示文摘AIM:To detect the contents of four active components of Salvia miltiorrhiza in various commercially available danshen crude drugs and preparations.METHODS:Commercially available danshen crude drugs from different sources,as well as danshen pills and intravenous injection preparations containing danshen alone or in combination with other herbs were collected.The composition of these danshen samples was analyzed using HPLC.Specifically,the amounts of magnesium tanshinoate B(MTB),danshensu,isotanshinone IIA,and cryptotanshinone were determined.In some of these samples,the content of MTB was further confirmed by liquid chromatography-tandem mass spectrometer (LC-MS)/MS method.RESULTS:There were great variations in the amount of the four active ingredients in the commercially available danshen crude drugs and drug preparations in this study.The amount of MTB was the highest among the four components measured in the crude drugs.However,the amounts of MTB in all danshen preparations were much lower than those in crude drugs.The 2 lipophilic components,isotanshinone IIA and cryptotanshinone,were very low or not detectable in both injection and oral preparations.CONCLUSION:MTB can be used to standardize the various forms of danshen crude drugs and drug preparations from different sources.In view of the variation in the amounts of MTB and other components,improvement in the production methods of danshen preparations is essential to ensure consistent amount of its active ingredients and reproducible pharmacological actions. | Susan Wai Sum LEUNG Yaw Loong SIOW Ricky Ying Keung MAN | 2002 | Acta Pharmacologica Sinica2002，23，12： | 6 |
| 5 | Effects of mindfulness-based intervention programs on sleep among people with common mental disorders:A systematic review and meta-analysis显示文摘BACKGROUND Sleep problems are particularly prevalent in people with depression or anxiety disorder.Although mindfulness has been suggested as an important component in alleviating insomnia,no comprehensive review and meta-analysis has been conducted to evaluate the effects of different mindfulness-based intervention(MBI)programs on sleep among people with depression or anxiety disorder.AIM To compare the effects of different MBI programs on sleep among people with depression or anxiety disorder.METHODS Related publications in Embase,Medline,PubMed and PsycINFO databases were systematically searched from January 2010 to June 2020 for randomised controlled trials.Data were synthesized using a random-effects or a fixed-effects model to analyse the effects of various MBI programs on sleep problems among people with depression or anxiety disorder.The fixed-effects model was used when heterogeneity was negligible,and the random-effects model was used when heterogeneity was significant to calculate the standardised mean differences(SMDs)and 95%confidence intervals(CIs).RESULTS We identified 397 articles,of which 10 randomised controlled trials,involving a total of 541 participants,were included in the meta-analysis.Studies of internet mindfulness meditation intervention(IMMI),mindfulness meditation(MM),mindfulness-based cognitive therapy(MBCT),mindfulness-based stress reduction(MBSR)and mindfulness-based touch therapy(MBTT)met the inclusion criteria.The greatest effect sizes are reported in favour of MBTT,with SMDs of-1.138(95%CI:-1.937 to-0.340;P=0.005),followed by-1.003(95%CI:-1.645 to-0.360;P=0.002)for MBCT.SMDs of-0.618(95%CI:-0.980 to-0.257;P=0.001)and-0.551(95%CI:-0.842 to-0.260;P<0.0001)were reported for IMMI and MBSR in the pooling trials,respectively.Significant effects on sleep problem improvement are shown in all reviewed MBI programs,except MM,for which the effect size was shown to be nonsignificant.CONCLUSION All MBI programs(MBTT,MBCT,IMMI and MBSR),except MM,are effective options to improve sleep problems among people with depression or anxiety disorder. | Sunny Ho-Wan Chan Danielle Lui Hazel Chan Kelly Sum Ava Cheung Hayley Yip Chong Ho Yu | 2022 | World Journal of Psychiatry2022，12，4： | 5 |

| 7 | Chinese topical herbal medicine gives additive effect on pharmaceutical agent on fracture healing显示文摘OBJECTIVE:To investigate the efficacy on the combination of oral strontium ranelate(Sr R)with a topical Chinese herbal paste on facilitation of fracture healing.METHODS:An open fracture was created at the mid-shaft of the right tibia of rat.A herbal pastecalled CDR containing Honghua(Flos Carthami),Chuanxuduan(Radix Dipsaci Asperoidis)and Dahuang(Radix Et Rhizoma Rhei Palmati)was prepared.The rats were treated with either CDR topically on the fracture site,or Sr R orally,or their combinations.Bone turnover biochemical markers in serum were measured.Microarchitecture of the fracture was analyzed using micro-CT after 14 and 28 d,followed by histomorphometrical analysis.RESULTS:Micro-computed tomography analysis revealed that the combined treatment of CDR with600 mg/g Sr R significantly increased the total callus density,mineralized callus volume fraction,mineralized callus mineral content and mineralized callus density of the callus after 28 d of treatment.This result was consistent with the histomorphometrical analysis on the osteoid volume.Analysis of biochemical markers showed that the combined treatments reduced the bone resorption that occurs temporarily after fracture.CONCLUSION:This study demonstrated that the combined treatment of oral Sr R and topical CDR is effective to promote fracture healing by their additive effect on promoting bone formation and retarding bone resorption. | Siu Wing Sum Shiu Hoi Ting Shum Wai Ting Ko Chun Hay Lau Clara Bik San Hung Leung Kim Leung Ping Chung | 2019 | Journal of Traditional Chinese Medicine2019，39，6： | 4 |
| 8 | Reducing 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 | 2013 | World Journal of Gastroenterology2013，19，22： | 4 |

| 11 | Structural and luminescence studies of europium ions in lithium aluminium borophosphate glasses显示文摘Eu3+ doped borophosphate glasses with the chemical composition 20Li2O-30Al2O3-10B2O3-40P2O5-xEu2O3(where x=0.05 mol.%, 0.1 mol.%, 1.0 mol.%, 1.5 mol.% and 2.0 mol.%) were prepared by conventional melt quenching technique. The structural and luminescence properties of the prepared Eu3+ doped borophosphate glasses were studied and compared with reported results. The XRD pattern showed the amorphous nature of the prepared glasses. Whereas, the FTIR spectra revealed the vibrational modes in the prepared glasses. The bonding parameters( β and ?) were calculated through the excitation spectra. Judd–Ofelt(J–O) intensity parameters were calculated from the emission spectra and were used to determine transition probability(A), stimulated emission cross-section(σE P), radiative lifetime(τR) and branching ratios(βexp) for the transition 5D0→7Fj(j=1, 2, 3 and 4) of Eu3+ ions. Furthermore, the luminescence intensity ratio(R) of 5D0→7F2 to 5D0→7F1 transition was also calculated. Transition 5D0→7F2 had the highest value of stimulated emission cross-section and branching ratios and the results were comparable with the reported values. This indicated that the present glass is promising host material for Eu3+ doped fiber amplifiers. | Poh Sum Wong Ming Hua Wan Rosli Hussin Hendrik O.Lintang Salasiah Endud | 2014 | Journal of Rare Earths2014，32，7： | 3 |

| 13 | Origins of the long-range exciton diffusion in perovskite nanocrystal films: photon recycling vs exciton hopping显示文摘The outstanding optoelectronic performance of lead halide perovskites lies in their exceptional carrier diffusion properties.As the perovskite material dimensionality is reduced to exploit the quantum confinement effects,the disruption to the perovskite lattice,often with insulating organic ligands,raises new questions on the charge diffusion properties.Herein,we report direct imaging of>1μm exciton diffusion lengths in CH3NH3PbBr3 perovskite nanocrystal(PNC)films.Surprisingly,the resulting exciton mobilities in these PNC films can reach 10±2cm^(2)V^(-1) s^(-1),,which is counterintuitively several times higher than the carrier mobility in 3D perovskite films.We show that this ultralong exciton diffusion originates from both efficient inter-NC exciton hopping(via Forster energy transfer)and the photon recycling process with a smaller yet significant contribution.Importantly,our study not only sheds new light on the highly debated origins of the excellent exciton diffusion in PNC films but also highlights the potential of PNCs for optoelearonic applications. | David Giovanni Marcello Righetto Qiannan Zhang Jia Wei Melvin Lim Sankaran Ramesh Tze Chien Sum | 2021 | Light(Science & Applications)2021，10，1： | 3 |

| 15 | A rare case of Staphylococcus lugdunensis septicemia associated with myocarditis and atrioventricular block显示文摘Myocarditis is a relatively rare,possibly life-threatening disease characterized by the inflammation of the myocardium.111 The disease pathogenesis is primarily initiated by acute injury and necrosis of cardiomyocytes,leading to an inflammatory response mediated by the immune system that can potentially cause further aggravation of myocardial damage and organ dysfunction.Prognosis in patients with myocarditis depends on the clinical presentation,which ranges from an asymptomatic disease course to the concomitant development of cardiac arrhythmias,heart failure,cardiogenic shock and even the occurrence of death in extreme cases[1]. | Alex Tsz Lai Nganh Sharen Lee Tong LIU Mark Tam Ka Hou Christien Li Michelle Vangi Wong Michael Huen Sum Lam Gary Tse Ishan Lakhani | 2019 | Journal of Geriatric Cardiology2019，16，1： | 2 |
| 16 | The glycolytic process in endothelial cells and its implications显示文摘Endothelial cells play an obligatory role in regulating local vascular tone and maintaining homeostasis in vascular biology. Cell metabolism, converting food to energy in organisms, is the primary self-sustaining mechanism for cell proliferation and reproduction, structure maintenance, and fight-or-flight responses to stimuli. Four major metabolic processes take place in the energy-producing process, including glycolysis, oxidative phosphorylation, glutamine metabolism, and fatty acid oxidation. Among them, glycolysis is the primary energy-producing mechanism in endothelial cells. The present review focused on glycolysis in endothelial cells under both physiological and pathological conditions. Since the switches among metabolic processes precede the functional changes and disease developments, some prophylactic and/or therapeutic strategies concerning the role of glycolysis in cardiovascular disease are discussed. | Susan Wai Sum Leung Yi Shi | 2022 | Acta Pharmacologica Sinica2022，43，2： | 2 |

| 18 | Examining patterns of traditional chinese medicine use in pediatric oncology: A systematic review, meta-analysis and data-mining study显示文摘Background Traditional Chinese medicine(TCM)is becoming a popular complementary approach in pediatric oncology.However,few or no meta-analyses have focused on clinical studies of the use of TCM in pediatric oncology.Objective We explored the patterns of TCM use and its efficacy in children with cancer,using a systematic review,meta-analysis and data mining study.Search strategy We conducted a search of five English(Allied and Complementary Medicine Database,Embase,PubMed,Cochrane Central Register of Controlled Trials,and ClinicalTrials.gov)and four Chinese databases(Wanfang Data,China National Knowledge Infrastructure,Chinese Biomedical Literature Database,and VIP Chinese Science and Technology Periodicals Database)for clinical studies published before October 2021,using keywords related to“pediatric,”“cancer,”and“TCM.”Inclusion criteria We included studies which were randomized controlled trials(RCTs)or observational clinical studies,focused on patients aged<19 years old who had been diagnosed with cancer,and included at least one group of subjects receiving TCM treatment.Data extraction and analysis The methodological quality of RCTs and observational studies was assessed using the six-item Jadad scale and the Effective Public Healthcare Panacea Project Quality Assessment Tool,respectively.Meta-analysis was used to evaluate the efficacy of combining TCM with chemotherapy.Study outcomes included the treatment response rate and occurrence of cancer-related symptoms.Association rule mining(ARM)was used to investigate the associations among medicinal herbs and patient symptoms.Results The fifty-four studies included in this analysis were comprised of RCTs(63.0%)and observational studies(37.0%).Most RCTs focused on hematological malignancies(41.2%).The study outcomes included chemotherapy-induced toxicities(76.5%),infection rate(35.3%),and response,survival or relapse rate(23.5%).The methodological quality of most of the RCTs(82.4%)and observational studies(80.0%)was rated as“moderate.”In studies of leukemia patients,adding TCM to conventional treatment significantly improved the clinical response rate(odds ratio[OR]=2.55;95%confidence interval[CI]=1.49-4.36),lowered infection rate(OR=0.23;95%CI=0.13-0.40),and reduced nausea and vomiting(OR=0.13;95%CI=0.08-0.23).ARM showed that Radix Astragali,the most commonly used medicinal herb(58.0%),was associated with treating myelosuppression,gastrointestinal complications,and infection.Conclusion There is growing evidence that TCM is an effective adjuvant therapy for children with cancer.We proposed a checklist to improve the quality of TCM trials in pediatric oncology.Future work will examine the use of ARM techniques on real-world data to evaluate the efficacy of medicinal herbs and drug-herb interactions in children receiving TCM as a part of integrated cancer therapy. | Chun Sing Lam Li Wen Peng Lok Sum Yang Ho Wing Janessa Chou Chi-Kong Li Zhong Zuo Ho-Kee Koon Yin Ting Cheung | 2022 | Journal of Integrative Medicine2022，20，5： | 2 |
