| 2 | Protein 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 | 2018 | Hepatobiliary & Pancreatic Diseases International2018，17，6： | 34 |

| 6 | Self-tuning virtual synchronous generator control for improving frequency stability in autonomous photovoltaic-diesel microgrids显示文摘This paper investigates the use of a virtual synchronous generator(VSG) to improve frequency stability in an autonomous photovoltaic-diesel microgrid with energy storage. VSG control is designed to emulate inertial response and damping power via power injection from/to the energy storage system. The effect of a VSG with constant parameters(CP-VSG) on the system frequency is analyzed. Based on the case study, self-tuning algorithms are used to search for optimal parameters during the operation of the VSG in order to minimize the amplitude and rate of change of the frequency variations. The performances of the proposed self-tuning(ST)-VSG, the frequency droop method, and the CP-VSG are evaluated by comparing their effects on attenuating frequency variationsunder load variations. For both simulated and experimental cases, the ST-VSG was found to be more efficient than the other two methods in improving frequency stability. | Rongliang SHI Xing ZHANG Chao HU Haizhen XU Jun GU Wei CAO | 2018 | Journal of Modern Power Systems and Clean Energy2018，6，3： | 27 |

| 14 | Leap Motion-based virtual reality training for improving motor functional recovery of upper limbs and neural reorganization in subacute stroke patients显示文摘Virtual reality is nowadays used to facilitate motor recovery in stroke patients. Most virtual reality studies have involved chronic stroke patients; however, brain plasticity remains good in acute and subacute patients. Most virtual reality systems are only applicable to the proximal upper limbs(arms) because of the limitations of their capture systems. Nevertheless, the functional recovery of an affected hand is most difficult in the case of hemiparesis rehabilitation after a stroke. The recently developed Leap Motion controller can track the fine movements of both hands and fingers. Therefore, the present study explored the effects of a Leap Motion-based virtual reality system on subacute stroke. Twenty-six subacute stroke patients were assigned to an experimental group that received virtual reality training along with conventional occupational rehabilitation, and a control group that only received conventional rehabilitation. The Wolf motor function test(WMFT) was used to assess the motor function of the affected upper limb; functional magnetic resonance imaging was used to measure the cortical activation. After four weeks of treatment, the motor functions of the affected upper limbs were significantly improved in all the patients, with the improvement in the experimental group being significantly better than in the control group. The action performance time in the WMFT significantly decreased in the experimental group. Furthermore, the activation intensity and the laterality index of the contralateral primary sensorimotor cortex increased in both the experimental and control groups. These results confirmed that Leap Motion-based virtual reality training was a promising and feasible supplementary rehabilitation intervention, could facilitate the recovery of motor functions in subacute stroke patients. The study has been registered in the Chinese Clinical Trial Registry(registration number: Chi CTR-OCH-12002238). | Zun-rong Wang Ping Wang Liang Xing Li-ping Mei Jun Zhao Tong Zhang | 2017 | Neural Regeneration Research2017，12，11： | 19 |
| 15 | Porphyrin-like Fe-N4 sites with sulfur adjustment on hierarchical porous carbon for different rate-determining steps in oxygen reduction reaction显示文摘We developed a strategy based on coordination polymer to synthesize singleatom site Fe/N and S-codoped hierarchical porous carbon (Fe1/N,S-PC).The as-obtained Fe1/N,S-PC exhibited superior oxygen reduction reaction (ORR) performance with a half-wave potential (Ev2,0.904 V vs.RHE) that was better than that of commercial Pt/C (E1/2,0.86 V vs.RHE),single-atom site Fe/N-doped hierarchical porous carbon (Fe1/N-PC) without S-doped (E1/2,0.85 V vs.RHE),and many other nonprecious metal catalysts in alkaline medium.Moreover,the Fe1/N,S-PC revealed high methanol tolerance and firm stability.The excellent electrocatalytic activity of Fe1/N,S-PC is attributed to the synergistic effects from the atomically dispersed porphyrin-like Fe-N4 active sites,the heteroatom codoping (N and S),and the hierarchical porous structure in the carbon materials.The calculation based on density functional theory further indicates that the catalytic performance of Fe1/N,S-PC is better than that of Fe1/N-PC owing to the sulfur doping that yielded different rate-determining steps. | Konglin Wu Xin Chen Shoujie Liu Yuan Pan Weng-Chon Cheong Wei Zhu Xing Cao Rongan Shen Wenxing Chen Jun LUO Wensheng Yan Lirong Zheng Zheng Chen Dingsheng Wang Qing Peng Chen Chen Yadong Li | 2018 | Nano Research2018，11，12： | 18 |

| 19 | Clinical practice guidelines on liver transplantation for hepatocellular carcinoma in China(2018 edition)显示文摘Introduction Over 300000 people in China die each year of hepatocellular carcinoma(HCC),which accounts for approximately half of HCCrelated deaths worldwide.Liver transplantation(LT)is generally recognized as one of the most effective therapeutic approaches for end-stage liver diseases.Since the beginning of the second LT boom in the 1990s,LT in China has been developed rapidly with professional and large-scale trends,and it is approaching or has reached the level of developed countries in terms of quantity and quality.According to the China Liver Transplant Registry,the number of transplants for HCC accounted for 36.8%of the total number of LT cases during the past 5 years in the mainland of China.In order to develop an effective,safe and standardized protocol to guide the national LT practice,the clinical guidelines of LT for HCC was launched in 2014 by multidisciplinary experts from Chinese Society of Organ Transplantation,Chinese Medical Association and Chinese Association of Organ Transplantation,Chinese Medical Doctor Association.Recently,there have been new clinical and scientific advances in the field of LT and to keep abreast of these achievements,the original clinical practice guidelines need to be updated. | Xiao Xu Jun Chen Qiang Wei Zhi-Kun Liu a Zhe Yang Ming Zhang Guo-Ying Wang Jie Gao Zhao-Xu Yang Wen-Yuan Guo Tong-Hai Xing Zhou Shao Qin-Fen Xie Shu-Sen Zheng | 2019 | Hepatobiliary & Pancreatic Diseases International2019，18，4： | 14 |
| 20 | Topographic differentiations of biological soil crusts and hydraulic properties in fixed sand dunes, Tengger Desert显示文摘Biological soil crusts(BSCs) play an important role in surface soil hydrology. Soils dominated with moss BSCs may have higher infiltration rates than those dominated with cyanobacteria or algal BSCs. However, it is unnown whether improved infiltration in moss BSCs is accompanied by an increase in soil hydraulic conductivity or water retention capacity. We investigated this question in the Tengger Desert, where a 43-year-old revegetation program has promoted the formation of two distinct types of BSCs along topographic positions, i.e. the moss-dominated BSCs on the interdune land and windward slopes of the fixed sand dunes, and the algal-dominated BSCs on the crest and leeward slopes. Soil water retention capacity and hydraulic conductivity were measured using an indoor evaporation method and a field infiltration method. And the results were fitted to the van Genuchten–Mualem model. Unsaturated hydraulic conductivities under greater water pressure(<–0.01 MPa) and water retention capacities in the entire pressure head range were higher for both crust types than for bare sand. However, saturated and unsaturated hydraulic conductivities in the near-saturation range(>–0.01 MPa) showed decreasing trends from bare sand to moss crusts and to algal crusts. Our data suggested that topographic differentiation of BSCs significantly affected not only soil water retention and hydraulic conductivities, but also the overall hydrology of the fixed sand dunes at a landscape scale, as seen in the reduction and spatial variability in deep soil water storage. | Zhi Shan ZHANG Yong Le CHEN Bin Xing XU Lei HUANG Hui Juan TAN Xue Jun DONG | 2015 | Journal of Arid Land2015，7，2： | 13 |
