1Hepatocellular carcinoma: current management and recent advances显示文摘BACKGROUND: Hepatocellular carcinoma (HCC) is a major health problem worldwide. It is the fifth most common cancer in the world, and the third most common cause of cancer-related death. Without specific treatment, the prognosis is very poor. The goal of management is 'cancer control' - a reduction in its incidence and mortality as well as an improvement in the quality of life of patients with HCC and their families. This article aims to review the current management of HCC and its recent advances. DATA SOURCES: A MEDLINE database search was performed to identify relevant article using the keyworks 'hepatocellular carcinoma', 'hepatectomy', 'liver transplantation', and 'local ablative therapy'. Additional papers and book chapters were identified by a manual search of the references from the key articles. RESULTS: Liver resection and liver transplantation remain the options that give the best chance of a cure. Recent evidence suggests that local ablative therapy may offer comparable survival results in patients with small HCC, and preserved liver function. Transarterial chemoembolization (TACE) is the most promising palliative modality for unresectable HCC, but other techniques, such as transarterial radioembolization (TARE), and local ablative therapy, have also shown comparable results. CONCLUSIONS: Early diagnosis of HCC remains a key goal in improving the prognosis of patients. During the last two decades, operative mortality and surgical outcome of liver resection and liver transplantation for HCC have improved. Progress also has been made in multi-modality therapy which can increase the chance of survival and improve the quality of life for patients with advanced HCC.Wan-Yee Lau Eric C. H.

4Protein induced by vitamin K absence or antagonist-Ⅱ versus alpha-fetoprotein in the diagnosis of hepatocellular carcinoma: A systematic review with meta-analysis显示文摘Background: As a promising biomarker of hepatocellular carcinoma(HCC), protein induced by vitamin K absence or antagonist-Ⅱ(PIVKA-Ⅱ) has been studied extensively. However, its diagnostic capability varies across HCC studies. This study aimed to compare the performance of PIVKA-Ⅱ with alpha-fetoprotein(AFP) in the diagnosis of HCC. Data sources: A systematic literature search was conducted to identify the studies from MEDLINE, Embase and Cochrane Library Databases, which were published up to December 20, 2017 to compare the diagnostic capability of PIVKA-Ⅱ and AFP for HCC. The data were pooled using random effects model. Pooled sensitivity and specificity were calculated. Summary receiver operating characteristic curve(ROC) was employed to evaluate the diagnostic accuracy of each marker. Results: Thirty-one studies were included. The pooled sensitivity(95% CI) of PIVKA-Ⅱ and AFP was 0.66(0.65–0.68) and 0.66(0.65–0.67), respectively in diagnosis of HCC; and the corresponding pooled specificity(95% CI) was 0.89(0.88–0.90) and 0.84(0.83–0.85), respectively. The area under the ROC curve(AUC) of PIVKA-Ⅱ and AFP was 0.856(0.817–0.895) and 0.770(0.728–0.811), respectively. Subgroup analysis showed that PIVKA-Ⅱ was superior to AFP in terms of the AUC for both small HCC( < 3 cm) [0.863(0.825–0.901) vs 0.717(0.658–0.776)] and large HCC( ≥ 3 cm) [0.854(0.811–0.897) vs 0.729(0.682–0.776)]; for American [0.926(0.897–0.955) vs 0.698(0.594–0.662)], European [0.772(0.743–0.801) vs 0.628(0.594–0.662)], Asian [0.838(0.812–0.864) vs 0.785(0.764–0.806)] and African [0.812(0.794–0.840) vs 0.721(0.675–0.767)] HCC patients; and for HBV-related [0.909(0.866–0.951) vs 0.714(0.673–0.755)] and mixed-etiology [0.847(0.821–0.873) vs 0.794(0.772–0.816)] HCC. Conclusion: This meta-analysis indicates that PIVKA-Ⅱ is better than AFP in terms of the accuracy for diagnosing HCC, regardless of tumor size, patient ethnic group, or HCC etiology.Hao Xing Yi-Jie Zheng Jun Han Han Zhang Zhen-Li Li Wan-Yee Lau Feng Shen Tian Yang 2018Hepatobiliary & Pancreatic Diseases International2018,17,6:34

6Methods of vascular control technique during liver resection:a comprehensive review显示文摘BACKGROUND:Significant hemorrhage together with blood transfusion increases postoperative morbidity and mortality of hepatic resection.Hepatic vascular occlusion is effective in minimizing bleeding during hepatic parenchymal transection.This article aimed to review the current role and status of various techniques of hepatic vascular occlusion during hepatic resection.DATA SOURCES:The relevant manuscripts were identified by searching MEDLINE,and PubMed for articles published between January 1980 and April 2010 using the keywords ' vascular control','vascular clamping','vascular exclusion' and 'hepatectomy'.Additional papers were identified by a manual search of the references from the key articles.RESULTS:One randomized controlled trial(RCT) and 5 RCTs showed intermittent Pringle maneuver and ischemic preconditioning followed by continuous Pringle maneuver were superior to continuous Pringle maneuver alone,respectively.Two RCTs compared the outcomes of hepatectomy with and without intermittent Pringle maneuver.One showed Pringle maneuver to be beneficial,while the other failed to show any benefit.One RCT showed that ischemic preconditioning had significantly less blood loss than using intermittent Pringle maneuver.Four RCTs evaluated the use of hemihepatic vascular occlusion.One RCT showed it had significantly less blood loss than Pringle maneuver,while the other 3 showed no significant difference.Only 1 RCT showed it had significantly less liver ischemic injury.No RCT had been carried out to assess segmental vascular occlusion.Two RCTs compared the outcomes of total hepatic vascular exclusion(THVE) and Pringle maneuver.One RCT showed THVE resulted in similar blood loss,but a higher postoperative complication.The other RCT showed less blood loss using THVE but the postoperative complication rate was similar.Both studies showed similar degree of liver ischemic injury.Only one RCT showed that selective hepatic vascular exclusion(SHVE) had less blood loss and liver ischemic injury than Pringle maneuver.CONCLUSION:Due to the great variations in these studies,it is difficult to draw a definitive conclusion on the best technique of hepatic vascular control.Wan-Yee Lau Eric C.H.Lai Stephanie H.Y.Lau 2010Hepatobiliary & Pancreatic Diseases International2010,9,5:27

9Molecular mechanisms of viral hepatitis induced hepatocellular carcinoma显示文摘Chronic infection with viral hepatitis affects half a billion individuals worldwide and can lead to cirrhosis,cancer,and liver failure.Liver cancer is the third leading cause of cancer-associated mortality,of which hepatocellular carcinoma(HCC)represents 90%of all primary liver cancers.Solid tumors like HCC are complex and have heterogeneous tumor genomic profiles contributing to complexity in diagnosis and management.Chronic infection with hepatitis B virus(HBV),hepatitis delta virus(HDV),and hepatitis C virus(HCV)are the greatest etiological risk factors for HCC.Due to the significant role of chronic viral infection in HCC development,it is important to investigate direct(viral associated)and indirect(immune-associated)mechanisms involved in the pathogenesis of HCC.Common mechanisms used by HBV,HCV,and HDV that drive hepatocarcinogenesis include persistent liver inflammation with an impaired antiviral immune response,immune and viral protein-mediated oxidative stress,and deregulation of cellular signaling pathways by viral proteins.DNA integration to promote genome instability is a feature of HBV infection,and metabolic reprogramming leading to steatosis is driven by HCV infection.The current review aims to provide a brief overview of HBV,HCV and HDV molecular biology,and highlight specific viral-associated oncogenic mechanisms and common molecular pathways deregulated in HCC,and current as well as emerging treatments for HCC.Simmone D'souza Keith CK Lau Carla S Coffin Trushar R Patel 2020World Journal of Gastroenterology2020,26,38:25
10Optical cross-talk reduction in a quantumdot-based full-color micro-light-emitting-diode display by a lithographic-fabricated photoresist mold显示文摘In this study, a full-color emission red–green–blue(RGB) quantum-dot(QD)-based micro-light-emitting-diode(micro-LED) array with the reduced optical cross-talk effect by a photoresist mold has been demonstrated. The UV micro-LED array is used as an efficient excitation source for the QDs. The aerosol jet technique provides a narrow linewidth on the micrometer scale for a precise jet of QDs on the micro-LEDs. To reduce the optical cross-talk effect,a simple lithography method and photoresist are used to fabricate the mold, which consists of a window for QD jetting and a blocking wall for cross-talk reduction. The cross-talk effect of the well-confined QDs in the window is confirmed by a fluorescence microscope, which shows clear separation between QD pixels. A distributed Bragg reflector is covered on the micro-LED array and the QDs' jetted mold to further increase the reuse of UV light.The enhanced light emission of the QDs is 5%, 32%, and 23% for blue, green, and red QDs, respectively.HUANG-YU LIN CHIN-WEI SHER DAN-HUA HSIEH XIN-YIN CHEN HUANG-MING PHILIP CHEN TENG-MING CHEN KEI-MAY LAU CHYONG-HUA CHEN CHIEN-CHUNG LIN HAO-CHUNG KUO 2017Photonics Research2017,5,5:26
11The current role of neoadjuvant/adjuvant/chemoprevention therapy in partial hepatectomy for hepatocellular carcinoma:a systematic review显示文摘BACKGROUND:Following curative treatment for hepato-cellular carcinoma(HCC),50%-90% of postoperative death is due to recurrent disease.Intra-hepatic recurrence is frequently the only site of recurrence.Thus,any neoadjuvant or adjuvant therapy,which can decrease or delay the incidence of intra-hepatic recurrence,or any cancer chemoprevention which can prevent a new HCC from developing in the liver remnant,will improve the results of liver resection.This article systematically reviewed the current evidence of neoadjuvant,adjuvant, and chemoprevention in partial hepatectomy of HCC. DATA SOURCES:Studies were identified by searching MEDLINE and PubMed databases for articles from January 1990 to November 2008 using the keywords 'hepatocellular carcinoma','hepatectomy','adjuvant therapy','neoadjuvant therapy',and'regional therapy'. Additional papers and book chapters were identified by a manual search of the references from the key articles. RESULTS:Neoadjuvant transarterial chemoembolization or adjuvant regional transarterial chemotherapy± embolization+systemic chemotherapy did not add benefit. Both adjuvant transarterial radioembolization with 131 I-lipiodol and adjuvant systemic interferon showed promising results.However,there were only a limited number of such studies.CONCLUSIONS:Further randomized controlled studies need to be carried out.Currently,there is no consensus on a standard neoadjuvant/adjuvant/chemoprevention therapy in partial hepatectomy for HCC.Wan-Yee Lau Eric C.H.Lai Stephanie H.Y.Lau 2009Hepatobiliary & Pancreatic Diseases International2009,8,2:24

14Laparoscopic liver resection under hemihepatic vascular inflow occlusion using the lowering of hilar plate approach显示文摘BACKGROUND: With advances in technology, laparoscopic liver resection is widely accepted. Laparoscopic liver resection under hemihepatic vascular inflow occlusion has advantages over the conventional total hepatic inflow occlusion using the Pringle's maneuver, especially in patients with cirrhosis.METHOD: From November 2011 to August 2012, eight consecutive patients underwent laparoscopic liver resection under hemihepatic vascular inflow occlusion using the lowering of hilar plate approach with biliary bougie assistance.RESULTS: The types of liver resection included right hepatectomy(n1), right posterior sectionectomy(n1), left hepatectomy and common bile duct exploration(n1), segment 4b resection(n1), left lateral sectionectomy(n2), and wedge resection(n2). Four patients underwent right and 4 left hemihepatic vascular inflow occlusion. Four patients had cirrhosis. The mean operation time was 176.3 minutes. The mean time taken to achieve hemihepatic vascular inflow occlusion was 24.3minutes. The mean duration of vascular inflow occlusion was54.5 minutes. The mean intraoperative blood loss was 361 mL.No patient required blood transfusion. Postoperatively, one patient developed bile leak which healed with conservative treatment. No postoperative liver failure and mortality occurred. The mean hospital stay of the patients was 7 days.CONCLUSION: Our technique of hemihepatic vascular inflow vascular occlusion using the lowering of hilar plate approachwas safe, and it improved laparoscopic liver resection by minimizing blood loss during liver parenchymal transection.Ying-Jun Chen Zuo-Jun Zhen Huan-Wei Chen Eric CH Lai Fei-Wen Deng Qing-Han Li Wan Yee Lau 2014Hepatobiliary & Pancreatic Diseases International2014,13,5:23
15Repetitive transcranial magnetic stimulation for lower extremity motor function in patients with stroke:a systematic review and network meta-analysis显示文摘Transcranial magnetic stimulation,a type of noninvasive brain stimulation,has become an ancillary therapy for motor function rehabilitation.Most previous studies have focused on the effects of repetitive transcranial magnetic stimulation(rTMS)on motor function in stroke patients.There have been relatively few studies on the effects of different modalities of rTMS on lower extremity motor function and corticospinal excitability in patients with stroke.The MEDLINE,Embase,Cochrane Library,ISI Science Citation Index,Physiotherapy Evidence Database,China National Knowledge Infrastructure Library,and ClinicalTrials.gov databases were searched.Parallel or crossover randomized controlled trials that addressed the effectiveness of rTMS in patients with stroke,published from inception to November 28,2019,were included.Standard pairwise meta-analysis was conducted using R version 3.6.1 with the“meta”package.Bayesian network analysis using the Markov chain Monte Carlo algorithm was conducted to investigate the effectiveness of different rTMS protocol interventions.Network meta-analysis results of 18 randomized controlled trials regarding lower extremity motor function recovery revealed that low-frequency rTMS had better efficacy in promoting lower extremity motor function recovery than sham stimulation.Network meta-analysis results of five randomized controlled trials demonstrated that highfrequency rTMS led to higher amplitudes of motor evoked potentials than low-frequency rTMS or sham stimulation.These findings suggest that rTMS can improve motor function in patients with stroke,and that low-frequency rTMS mainly affects motor function,whereas high-frequency rTMS increases the amplitudes of motor evoked potentials.More highquality randomized controlled trials are needed to validate this conclusion.The work was registered in PROSPERO(registration No.CRD42020147055)on April 28,2020.Yun-Juan Xie Yi Chen Hui-Xin Tan Qi-Fan Guo Benson Wui-Man Lau Qiang Gao 2021Neural Regeneration Research2021,16,6:20
16不同左心室射血分数老年充血性心力衰竭患者药物治疗的临床研究显示文摘目的探讨充血性心力衰竭(心衰)患者的临床特征和药物治疗情况以及不同左心室射血分数(LVEF)心衰患者的并发症与药物治疗情况。方法连续调查2001年1月—2002年1月香港大学玛丽医院收住60岁以上的老年充血性心衰患者,符合ICD9CM诊断标准,并用弗明翰研究标准确诊,共计1074例次,收集入院时及入院3d内的超声心动图、心电图、X线胸片等检查结果以及患者出院时转归、出院带药情况。结果1女性充血性心衰患者几乎为男性患者的2倍,年龄≥65岁者占95.5%,≥80岁者占50.6%,按美国纽约心脏协会(NYHA)心功能分级,和级占70.2%,521例(占48.5%)入院治疗1次。2充血性心衰的主要并发症为糖尿病和高血压。3399例次行超声心动图检查者中,208例次(占52.1%)LVEF<0.50,191例次(占47.9%)LVEF≥0.50的患者更倾向于女性,年龄≥80岁,而冠心病及糖尿病较少发生,心房颤动84例次(占44.0%)占多数(P<0.05)。糖尿病、完全性左束支传导阻滞及心肌梗死病史常伴随LVEF<0.50的患者(P<0.05)。4大部分患者均接受利尿剂治疗,LVEF<0.50的患者中使用血管紧张素转换酶抑制剂(ACEI)131例次(占63.0%),地高辛47例次(占22.6%),β受体阻滞剂25例次(占12.0%),钙阻滞剂29例次(占13.9%),而LVEF≥0.50的患者分别有119例次(62.3%)、67例次(35.1%)、18例次(占9.4%)和35例次(占18.3%)使用上述药物,地高辛多用在LVEF≥0.50的患者(P<0.05)。结论1LVEF<0.50与≥0.50的充血性心衰患者单从临床症状和体征上较难区别,目前强调对每个心衰患者尽可能进行早期超声心动图检查,这是区别两类心衰的重要手段。2ACEI、β受体阻滞剂的使用与治疗指南还有一定距离。3尽早地区分LVEF<0.50与≥0.50充血性心衰患者将有利于抗心衰治疗。詹红 Tse Hung-fat 曹晶茗 Lau Cpu-pak 2006中国危重病急救医学2006,18,4:20
17Optimal central venous pressure during partial hepatectomy for hepatocellular carcinoma显示文摘BACKGROUND:Low central venous pressure(CVP) affects hemodynamic stability and tissue perfusion.This prospective study aimed to evaluate the optimal CVP during partial hepatectomy for hepatocellular carcinoma(HCC).METHODS:Ninety-seven patients who underwent partial hepatectomy for HCC had their CVP controlled at a level of 0 to 5 mmHg during hepatic parenchymal transection.The systolic blood pressure(SBP) was maintained,if possible,at 90 mmHg or higher.Hepatitis B surface antigen was positive in 90 patients(92.8%) and cirrhosis in 84 patients(86.6%).Pringle maneuver was used routinely in these patients with clamp/unclamp cycles of 15/5 minutes.The average clamp time was 21.4±8.0 minutes.These patients were divided into 5 groups based on the CVP:group A:0-1 mmHg;B:1.1-2 mmHg;C:2.1-3 mmHg;D:3.1-4 mmHg and E:4.1-5 mmHg.The blood loss per transection area during hepatic parenchymal transection and the arterial blood gas before and after liver transection were analyzed.RESULTS:With active fluid load,a constant SBP ≥90 mmHg which was considered as optimal was maintained in 18.6% in group A(95% CI:10.8%-26.3%);39.2% in group B(95% CI:29.5%-48.9%);72.2% in group C(95% CI:63.2%-81.1%);89.7% in group D(95% CI:83.6%-95.7%);and 100% in group E(95% CI:100%-100%).The blood loss per transection area during hepatic parenchymal transection decreased with a decrease in CVP.Compared to groups D and E,blood loss in groups A,B and C was significantly less(analysis of variance test,P<0.05).Compared with the baseline,the blood oxygenation decreased significantly when the CVP was reduced.Base excess and HCO 3-in groups A and B were significantly decreased compared with those in groups C,D and E(P<0.05).CONCLUSION:In consideration of blood loss,SBP,base excess and HCO 3-,a CVP of 2.1-3 mmHg was optimal in patients undergoing partial hepatectomy for HCC.Cheng-Xin Lin Ya Guo Wan Yee Lau Guang-Ying Zhang Yi-Ting Huang Wen-Zheng He Eric CH Lai 2013Hepatobiliary & Pancreatic Diseases International2013,12,5:19

19Exogenous neural stem cell transplantation for cerebral ischemia显示文摘Cerebral ischemic injury is the main manifestation of stroke,and its incidence in stroke patients is 70–80%.Although ischemic stroke can be treated with tissue-type plasminogen activator,its time window of effectiveness is narrow.Therefore,the incidence of paralysis,hypoesthesia,aphasia,dysphagia,and cognitive impairment caused by cerebral ischemia is high.Nerve tissue regeneration can promote the recovery of the aforementioned dysfunction.Neural stem cells can participate in the reconstruction of the damaged nervous system and promote the recovery of nervous function during self-repair of damaged brain tissue.Neural stem cell transplantation for ischemic stroke has been a hot topic for more than 10 years.This review discusses the treatment of ischemic stroke with neural stem cells,as well as the mechanisms of their involvement in stroke treatment.Ling-Yi Liao Benson Wui-Man Lau Dalinda Isabel Sánchez-Vidana Qiang Gao 2019Neural Regeneration Research2019,14,7:19
