| 1 | Prevalence of minimal hepatic encephalopathy and quality of life evaluations in hospitalized cirrhotic patients in China显示文摘AIM:To investigate the prevalence of minimal hepatic encephalopathy(MHE)and to assess corresponding health-related quality of life(HRQoL)in hospitalized cirrhotic patients in China.METHODS:This multi-center cross-sectional study included 16 teaching hospitals,which were members of 'Hepatobiliary Cooperation Group,Society of Gastroenterology,Chinese Medical Association',from different areas of China carried out between June and October in 2011.All the eligible hospitalized cirrhotic patients(n = 538)were required to complete triplicate number connection tests combined with one digit symbol test for diagnosing MHE.Patients' clinical examination data were complemented by a modified questionnaire assessing HRQoL.Written informed consent was obtained from each patient.RESULTS:Male was predominant(68.6%)in 519 patients who met the criteria of the study,with a mean age of 49.17 ± 11.02 years.The most common cause of liver cirrhosis was chronic hepatitis B(55.9%).The prevalence of MHE was 39.9% and varied by ChildPugh-Classification score(CPC-A:24.8%,CPC-B:39.4% and CPC-C:56.1%,P < 0.01).MHE(P < 0.01)and higher CPC scores(P < 0.01)were associated with a high HRQoL scores(reflecting poorer quality of life).The prevalence of MHE was proportionate to CPC(P = 0.01)and high quality of life scores(P = 0.01).CONCLUSION:Hospitalized cirrhotic patients have a high prevalence of MHE that is proportionate to the degree of liver function and HRQoL impairment. | Ji-Yao Wang Ning-Ping Zhang Bao-Rong Chi Yu-Qing Mi Li-Na Meng Ying-Di Liu Jiang-Bin Wang Hai-Xing Jiang Jin-Hui Yang Yun Xu Xiao Li Jian-Ming Xu Guo Zhang Xin-Min Zhou Yu-Zheng Zhuge De-An Tian Jin Ye Yu-Lan Liu | 2013 | World Journal of Gastroenterology2013，19，30： | 64 |
| 2 | Effect of probiotic treatment on cirrhotic patients with minimal hepatic encephalopathy: A meta-analysis显示文摘Background: Minimal hepatic encephalopathy(MHE) is an early and reversible form of hepatic encephalopathy. The documentations on the treatment with probiotics are inconsistent. The present meta-analysis was to verify the role of probiotics in the treatment of cirrhotic patients with MHE.Data sources: Seven electronic databases were searched for relevant randomized controlled trials(RCTs)published until July 2015. The effects of probiotics on serum ammonia, endotoxin, and MHE were evaluated.Results: A total of 14 RCTs(combined n = 1132) were included in the meta-analysis. When probiotics were compared to placebo or no treatment, probiotics were more likely to reduce values in the number connection test(NCT; week 4: MD =-30.25, 95% CI:-49.85 to-10.66), improve MHE(week 4: OR = 0.18,95% CI: 0.07 to 0.47; week 12: OR = 0.15, 95% CI: 0.07 to 0.32), and prevent overt HE progression(week4: OR = 0.22, 95% CI: 0.07 to 0.67) in patients with liver cirrhosis. When probiotics was compared to lactulose, probiotics tended to reduce serum ammonia levels(week 4: MD =-0.33 μmol/L, 95% CI:-5.39 to 4.74; week 8: MD = 6.22 μmol/L, 95% CI:-24.04 to 36.48), decrease NCT(week 8: MD = 3.93, 95% CI:-0.72 to 8.58), improve MHE(week 4: OR = 0.93, 95% CI: 0.45 to 1.91; week 12: OR = 0.73, 95% CI: 0.35 to 1.51) and prevent the development of overt HE(week 4: OR = 0.96, 95% CI: 0.17 to 5.44; week 12:OR = 2.7, 95% CI: 0.50 to 14.64) in patients with liver cirrhosis. However, lactulose appears to be more effective in reducing NCT values as compared to probiotics(week 4: MD = 6.7, 95% CI: 0.58 to 12.82).Conclusion: Probiotics can decrease serum ammonia and endotoxin levels, improve MHE, and prevent overt HE development in patients with liver cirrhosis. | Qing Cao Cheng-Bo Yu Shi-Gui Yang Hong-Cui Cao Ping Chen Min Deng Lan-Juan Li | 2018 | Hepatobiliary & Pancreatic Diseases International2018，17，1： | 25 |
| 3 | Psychometric hepatic encephalopathy score for diagnosis of minimal hepatic encephalopathy in China显示文摘AIM:To construct normal values for the tests of the psychometric hepatic encephalopathy score(PHES)and to evaluate its usefulness in the diagnosis of minimal hepatic encephalopathy(MHE)among Chinese individuals with cirrhosis.METHODS:The five tests of PHES,number connection test-A(NCT-A),number connection test-B,serial dotting test,line tracing test and digit symbol test(DST),were administered to all enrolled subjects in a quiet room with sufficient light.Cirrhotic subjects with overt HE were excluded by the West-Haven criteria and a detailed neurological examination.Based on the nomograms of healthy volunteers,the patients were classified as having MHE when their PHES was less than-4.RESULTS:In total,146 healthy volunteers completed all the PHES tests.Age and education years were confirmed to be predictors of all five tests.In total,53patients with liver cirrhosis completed the PHES.Of the patients with liver cirrhosis,24(45.3%),22(41.5%)and 7(13.2%)had Child-Pugh grades A,B and C,respectively.MHE was diagnosed in 26 patients(49.1%).Compared with compensated cirrhotic patients(Child A),decompensated cirrhotic patients(Child B and C)had a higher proportion of MHE(65.5%vs 29.2%).No differences in age and education years were found between the MHE and non-MHE groups.NCT-A and DST were able to diagnose MHE with a sensitivity of 76.9%and a specificity of 96.3%(AUC=0.866,K=0.735).CONCLUSION:The proportion of MHE is associated with liver function.NCT-A and DST are simple tools that can be used for the diagnosis of MHE in China. | Su-Wen Li Kai Wang Yong-Qiang Yu Hai-Bao Wang Yuan-Hai Li Jian-Ming Xu | 2013 | World Journal of Gastroenterology2013，19，46： | 21 |

| 5 | Quality of life in patients with minimal hepatic encephalopathy显示文摘Minimal hepatic encephalopathy(MHE) represents the mildest type of hepatic encephalopathy(HE). This condition alters the performance of psychometric tests by impairing attention, working memory, psychomotor speed, and visuospatial ability, as well as electrophysiological and other functional brain measures. MHE is a frequent complication of liver disease, affecting up to 80% of tested patients, depending of the diagnostic tools used for the diagnosis. MHE is related to falls, to an impairment in fitness to drive and the development of overt HE, MHE severely affects the lives of patients and caregivers by altering their quality of life(QoL) and their socioeconomic status. MHE is detected in clinically asymptomatic patients through appropriate psychometric tests and neurophysiological methods which highlight neuropsychological alterations such as video-spatial orientation deficits, attention disorders, memory, reaction times, electroencephalogram slowing, prolongation of latency evoked cognitive potentials and reduction in the critical flicker frequency. Several treatments have been proposed for MHE treatment such as non-absorbable disaccharides, poorly absorbable antibiotics such rifaximin, probiotics and branched chain amino acids. However, because of the multiple diagnosis methods, the various endpoints of treatment trials and the variety of agents used in trials, to date the treatment of MHE is not routinely recommended apart from on a case-by-case basis. Aim of this review is analyze the burden of MHE on QoL of patients and provide a brief summary of therapeutic approaches. | Lorenzo Ridola Silvia Nardelli Stefania Gioia Oliviero Riggio | 2018 | World Journal of Gastroenterology2018，24，48： | 14 |
| 6 | Sentinel node navigation surgery for gastric cancer: Overview and perspective显示文摘The sentinel node(SN) technique has been established for the treatment of some types of solid cancers to avoid unnecessary lymphadenectomy. If node disease were diagnosed before surgery, minimal surgery with omission of lymph node dissection would be an option for patients with early gastric cancer. Although SN biopsy has been well ascertained in the treatment of breast cancer and melanoma, SN navigation surgery(SNNS) in gastric cancer has not been yet universal due to the complicated lymphatic flow from the stomach. Satisfactory establishment of SNNS will result in the possible indication of minimally invasive surgery of gastric cancer. However, the results reported in the literature on SN biopsy in gastric cancer are widely divergent and many issues are still to be resolved, such as the collection method of SN, detection of micrometastasis in SN, and clinical benefit. The difference in the procedural technique and learning phase of surgeons is also varied the accuracy of SN mapping. In this review, we outline the current status of application for SNNS in gastric cancer. | Masakazu Yashiro Tasuku Matsuoka | 2015 | World Journal of Gastrointestinal Surgery2015，7，1： | 13 |
| 7 | Laparoscopic hepaticoplasty using gallbladder as a subcutaneous tunnel for hepatolithiasis显示文摘AIM:To investigate the feasibility,efficacy and safety of laparoscopic hepaticoplasty using gallbladder as subcutaneous tunnel and sphincter-of-Oddi preservation for hepatolithiasis.METHODS:From January 2010 to July 2013,six patients with hepatolithiasis were treated at our institution.All the patients underwent laparoscopic surgery.The procedures included common hepatic duct exploration,stone clearance by fiberoptic choledochoscopy,hilar bile duct hepaticoplasty with preservation of the sphincter of Oddi,anastomosis between the hilar bile duct and neck of the gallbladder,and establishment of a subcutaneous tunnel with the gallbladder.Two patients underwent left lateral hepatectomy simultaneously.Clinical data including operation time,intraoperative blood loss,operative morbidity,hospital mortality,stone clearance,and recurrence rate were analyzed.RESULTS:All patients successfully completed laparoscopic surgery.The mean length of hospital stay was4.5±0.9 d(range:3-6 d).The mean blood loss of the hepatectomy was 450 mL(range:200-700 mL),and the blood loss of the other four was 137±151 mL (range:50-400 mL).The mean operative time was 318±68 min(range:236-450 min).The operative morbidity and hospital mortality were zero.The immediate stone clearance rate was 100%.All patients were followed up for an average of 17 mo(range:7-36 mo).One of the six patients had abdominal mass with pain,and subcutaneous tunnel cholangiography showed severe gallbladder-biliary anastomotic stricture at 4 mo postoperatively.There was no stone recurrence and no cholangitis during follow-up.CONCLUSION:Laparoscopic hepaticoplasty using gallbladder with a subcutaneous tunnel and preserving the sphincter of Oddi is feasible,safe and effective for hepatholithiasis. | Long Cui Zhi Xu Xiao-Feng Ling Li-Xin Wang Chun-Sheng Hou Gang Wang Xiao-Si Zhou | 2014 | World Journal of Gastroenterology2014，20，12： | 13 |
| 8 | Rationalizing phonon dispersion for lattice thermal conductivity of solids显示文摘Lattice thermal conductivity(κL) is one of the most fundamental properties of solids. The acoustic–elastic-wave assumption, proposed by Debye(Debye P. Ann Phys 1912; 344: 789–839), has led to linear phonon dispersion being the most common approximation for understanding phonon transport over the past century. Such an assumption does not take into account the effect of a periodic boundary condition on the phonon dispersion, originating from the nature of periodicity on atomic arrangements. Driven by modern demands on the thermal functionality of materials, with κLranging from ultra-low to ultra-high,any deviation from the Debye approximation in real materials becomes more and more significant. This work takes into account the periodic boundary condition, and therefore rationalizes the phonon dispersion to be more realistic. This significantly improves the precision for quickly predicting κLwithout any fitting parameters, as demonstrated in hundreds of materials, and offers a theoretical basis rationalizing κLto be lower than the minimum currently accepted based on the Debye dispersion. This work paves the way for designing solids with expected κLand particularly inspires the advancement of low-κLmaterials for thermal energy applications. | Zhiwei Chen Xinyue Zhang Siqi Lin Lidong Chen Yanzhong Pei | 2018 | National Science Review2018，5，6： | 12 |
| 9 | Some open questions in the theory of generalized permutable subgroups显示文摘A subgroup H of a group G is said to be weakly s-supplemented in G if H has a supplement T in G such that H ∩ T HsG, where HsG is the largest s-permutable subgroup of G contained in H. This paper constructs an example to show that the open questions 6.3 and 6.4 in J Algebra, 315: 192–209 (2007) have negative solutions, and shows that in many cases Question 6.4 is positive. A series of known results are unified and generalized. | GUO WenBin XIE FengYan LI BaoJun | 2009 | Science China Mathematics2009，52，10： | 11 |
| 10 | Acute necrotizing pancreatitis: Surgical indications and technical procedures显示文摘Necrosis of pancreatic parenchyma or extrapancreatic tissues is present in 10%-20% of patients with acute pancreatitis, defining the necrotizing presentation frequently associated with high morbidity and mortality rates. During the initial phase of acute necrotizing pancreatitis the most important pillars of medical treatment are fluid resuscitation, early enteral nutrition, endoscopic retrograde colangiopancreatography if associated cholangitis and intensive care unit support. When infection of pancreatic or extrapancreatic necrosis occurs, surgical approach constitutes the most accepted therapeutic option. In this context, we have recently assited to changes in time for surgery(delaying the indication if possible to around 4 wk to deal with 'walledoff' necrosis) and type of access for necrosectomy: from a classical open approach(with closure over large-bore drains for continued postoperative lavage or semiopen techniques with scheduled relaparotomies), trends have changed to a 'step-up' philosophy with initial percutaneous drainage and posterior minimally invasive or endoscopic access to the retroperitoneal cavity for necrosectomy if no improvement has been previously achieved. These approaches are progressively gaining popularity and morbidity and mortality rates have decreased significantly. Therefore, a staged, multidisciplinary, step-up approach with minimally invasive or endoscopic access for necrosectomy is widely accepted nowadays for management of pancreatic necrosis. | José Manuel Aranda-Narváez Antonio Jesús González-Sánchez María Custodia Montiel-Casado Alberto Titos-García Julio Santoyo-Santoyo | 2014 | World Journal of Clinical Cases2014，2，12： | 10 |
| 11 | Critical flicker frequency for diagnosis and assessment of recovery from minimal hepatic encephalopathy in patients with cirrhosis显示文摘BACKGROUND:Minimal hepatic encephalopathy (MHE) impairs quality of life and predicts overt hepatic encephalopathy (HE) in cirrhotic patients.Diagnosis of MHE requires cumbersome tests.Lactulose is effective in the treatment of MHE.This study aimed to evaluate the use of critical flicker frequency (CFF) for the diagnosis of MHE in cirrhotic patients after treatment.METHODS:One hundred and ten patients were evaluated by psychometry (number connection tests A,B or figure connection tests A,B),P300 auditory event related potential (P300ERP),venous ammonia,and CFF for MHE.MHE was diagnosed by abnormal psychometry (>2SD age matched controls) and P300ERP.MHE patients were treated with lactulose for one month.Response was defined by normalization (<2SD of matched controls) of both psychometry and P300ERP.RESULTS:Of the 110 patients [Child Turcott Pugh score A:B:C 39:42:29,(age 41.6±11.6 years,M:F 82:28)],75 (68%) had abnormal results of psychometric tests,and 74 (67%) had prolonged P300ERP.Fifteen (20%) patients with abnormal results of psychometric tests had normal P300ERP.Thus sixty (54.5%) patients were diagnosed as having MHE.After treatment for one month,34 (57%) recovered while 26 (43%) continued to have abnormal resents of psychometric or P300ERP tests.CFF was <39 Hz in 72 (65.4%) patients before treatment and in 20 (33.3%) after treatment.CFF sensitivity,specificity,positive predictive value,negative predictive value,and diagnostic accuracy for the assessment of recovery of MHE were 65%,91%,85%,77% and 80%,respectively.CONCLUSION:CFF is a simple,relatively reliable,and accurate test without any dependence on age or literacy in the diagnosis and assessment of recovery of patients with MHE. | Praveen Sharma Barjesh Chander Sharma Shiv Kumar Sarin | 2010 | Hepatobiliary & Pancreatic Diseases International2010，9，1： | 10 |
| 12 | Step kinematic calibration of a 3-DOF planar parallel kinematic machine tool显示文摘This paper presents a novel step kinematic calibration method for a 3 degree-of-freedom(DOF) planar parallel kinematic machine tool,based on the minimal linear combinations(MLCs) of error parameters.The method using mapping of linear combinations of parameters in error transfer multi-parameters coupling system changes the modeling,identification and error compensation of geometric parameters in the general kinematic calibration into those of linear combinations of parameters.By using the four theorems of the MLCs,the sets of the MLCs that are respectively related to the relative precision and absolute precision are determined.All simple and feasible measurement methods in practice are given,and identification analysis of the set of the MLCs for each measurement is carried out.According to the identification analysis results,a step calibration including step measurement,step identification and step error compensation is determined by taking into account both measurement costs and observability.The experiment shows that the proposed method has the following merits:(1) the parameter errors that cannot influence precision are completely avoided;(2) it reflects the mapping of linear combinations of parameters more accurately and enhances the precision of identification;and(3) the method is robust,efficient and effective,so that the errors in position and orientation are kept at the same order of the measurement noise.Due to these merits,the present method is attractive for the 3-DOF planar parallel kinematic machine tool and can be also applied to other parallel kinematic machine tools with weakly nonlinear kinematics. | CHANG Peng,WANG JinSong,LI TieMin,LIU XinJun & GUAN LiWen Department of Precision Instruments and Mechanology,Tsinghua University,Beijing 100084,China | 2008 | Science China(Technological Sciences)2008，51，12： | 9 |

| 14 | Donor-Derived CD19-Targeted T Cell Infusion Eliminates B Cell Acute Lymphoblastic Leukemia Minimal Residual Disease with No Response to Donor Lymphocytes after Allogeneic Hematopoietic Stem Cell Transplantation显示文摘Leukemia relapse is still the leading cause of treatment failure after allogeneic hematopoietic stem cell transplantation (allo-HSCT) for B cell acute lymphoblastic leukemia (B-ALL). Relapsed patients with BALL after allo-HSCT have a very short median survival. Minimal residual disease (MRD) is predictive of forthcoming hematological relapse after hematopoietic stem cell transplantation (HSCT);furthermore, eliminating MRD effectively prevents relapse. Donor lymphoblastic infusion (DLI) is the main established approach to treat B-ALL with MRD after allo-HSCT. However, about one-third of patients with MRD are non-responsive to DLI and their prognosis worsens. Although donor-derived cluster of differentiation (CD)19-directed chimeric antigen receptor-modified (CAR) T cells (CART19s) can potentially cure leukemia, the efficiency and safety of infusions with these cells have not yet been investigated in patients with MRD after HSCT. Between September 2014 and February 2018, six patients each received one or more infusions of CART19s from HSCT donors. Five (83.33%) achieved MRD-negative remission, and one case was not responsive to the administration of CAR T cells. Three of the six patients are currently alive without leukemia. No patient developed acute graft-versus-host disease (aGVHD), and no patient died of cytokine release syndrome. Donor-derived CAR T cell infusions seem to be an effective and safe intervention for patients with MRD in B-ALL after allo-HSCT and for those who were not responsive to DLI. | Yifei Cheng Yuhong Chen Chenhua Yan Yu Wang Xiangyu Zhao Yao Chen Wei Han Lanping Xu Xiaohui Zhang Kaiyan Liu Shasha Wang Lungji Chang Lei Xiao Xiaojun Huang | 2019 | Engineering2019，5，1： | 7 |

| 16 | Interferon-α salvage treatment is effective for patients with acute leukemia/myelodysplastic syndrome with unsatisfactory response to minimal residual disease-directed donor lymphocyte infusion after allogeneic hematopoietic stem cell transplantation显示文摘The efficacy of salvage interferon-α(IFN-α) treatment was investigated in patients with unsatisfactory response to minimal residual disease (MRD)-directed donor lymphocyte infusion (DLI)(n=24). Patients who did not become MRD-negative at 1 month after DLI were those with unsatisfactory response and were eligible to receive salvage IFN-α treatment within 3 months of DLI. Recombinant human IFN-α-2b injections were subcutaneously administered 2–3 times a week for 6 months. Nine (37.5%), 6 (25.0%), and 3 (12.5%) patients became MRD-negative at 1, 2, and>2 months after the salvage IFN-α treatment, respectively. Two-year cumulative incidences of relapse and non-relapse mortality were 35.9% and 8.3%, respectively. Two-year probabilities of event-free survival, disease-free survival, and overall survival were 51.6%, 54.3%, and 68.0%, respectively. Outcomes of patients subjected to salvage IFN-α treatment after DLI were significantly better than those with persistent MRD without IFN-α treatment. Moreover, clinical outcomes were comparable between the salvage DLI and IFN-α treatment groups. Thus, salvage IFN-α treatment may help improve the outcome of patients with unsatisfactory responses to MRD-directed DLI and could be a potential salvage treatment for these patients after allogeneic hematopoietic stem cell transplantation. | Xiaodong Mo Xiaohui Zhang Lanping Xu Yu Wang Chenhua Yan Huan Chen Yuhong Chen Wei Han Fengrong Wang Jingzhi Wang Kaiyan Liu Xiaojun Huang | 2019 | Frontiers of Medicine2019，13，2： | 6 |
| 17 | A Gene-Pool Based Genetic Algorithm for TSP显示文摘Based on the analysis of previous genetic algorithms (GAs) for TSP, a novel method called Ge- GA is proposed. It combines gene pool and GA so as to direct the evolution of the whole population. The core of Ge- GA is the construction of gene pool and how to apply it to GA. Different from standard GAs, Ge- GA aims to enhance the ability of exploration and exploitation by incorporating global search with local search. On one hand a local search called Ge- Lo-calSearch operator is proposed to improve the solution quality, on the other hand the modified Inver-Over operator called Ge InverOver is considered as a global search mechanism to expand solution space of local minimal. Both of these operators are based on the gene pool. Our algorithm is applied to 11 well-known traveling salesman problems whose numbers of cities are from 70 to 1577 cities. The experiments results indicate that Ge- GA has great robustness for TSP. For each test instance, the average value of solution quality, found in accepted time, | Yang Hui, Kang Li-shan, Chen Yu-pingState Key Laboratory of Software Engineering, Wuhan University, Wuhan 430072, Hubei, China | 2003 | Wuhan University Journal of Natural Sciences2003，8，S1： | 6 |

| 19 | A new sequential learning algorithm for RBF neural networks显示文摘Due to their inherent imperfections, it is hard to use the static neural networks for nonlinear time-varying process modeling and prediction, and the minimal resource allocation network (MRAN) is difficult to be realized for its too many regulation parameters. A new sequential learning algorithm for radial basis function (RBF) neural networks based on local projection named Local Projection Network (LPN) is proposed in this paper. The results of validation for several benchmark problems with the new algorithm show that the presented LPN not only has the same level as M-RAN in network size and precision of the outputs, but also has fewer regulation parameters and is more predictable. | YANG Ge1, LV Jianhong1 & LIU Zhiyuan2 1.

| 20 | Single port laparoscopic right hemicolectomy for ileocolic intussusception显示文摘A 36-year-old male was admitted with right lower abdominal pain and diarrhea for more than 3 mo. Colonoscopy and a barium enema study revealed a submucosal tumor over the cecum, but computed tomography showed an ileal lipoma. There was no definitive diagnosis preoperatively, but ileocolic intussusception was noted during surgery. Single port laparoscopic radical right hemicolectomy was performed because intra-operative reduction failed. The histological diagnosis of the resected tumor was lipoma. Single port laparoscopic surgery has recently been proven to be safe and feasible. There are advantages compared with conventional laparoscopic surgery, such as smaller incision wounds, fewer port site complications, and easier conversion. However, there are some drawbacks which need to be overcome, such as difficulties in triangulation and instrument clashing. If there are no contraindications to laparoscopy, single port laparoscopic surgery can be performed safely and should be considered for diagnosis and treatment of intussusception in adults. Here, we report the first case of ileocolic intussusception successfully treated by single port laparoscopic surgery. | Jia-Hui Chen Jhe-Syun Wu | 2013 | World Journal of Gastroenterology2013，19，9： | 5 |
