| 1 | Bile duct injuries associated with laparoscopic and open cholecystectomy: Sixteen-year experience显示文摘AIM: To summarize the experience in diagnosis, management and prevention of iatrogenic bile duct injury (IBDI). METHODS: A total of 210 patients with bile duct injury occurred during cholecystectomy admitted to Hunan Provincial People’s Hospital from March 1990 to March 2006 were included in this study for retrospective analysis. RESULTS: There were 59.5% (103/173) of patients with IBDI resulting from the wrong identification of the anatomy of the Calot’s triangle during cholecystectomy. The diagnosis of IBDI was made on the basis of clinical features, diagnostic abdominocentesis and imaging findings. Abdominal B ultrasonography (BUS) was the most popular way for IBDI with a diagnostic rate of 84.6% (126/149). Magnetic resonance cholangiography (MRC) could reveal the site of injury, the length of injured bile duct and variation of bile duct tree with a diagnostic rate 100% (45/45). According to the site of injury, IBDI could be divided into six types. The most common type (type 3) occurred in 76.7% (161/210) of the patients and was treated with partial resection of the common hepatic duct and common bile duct. One hundred and seventy-six patients were followed up. The mean follow-up time was 3.7 (range 0.25-10) years. Good results were achieved in 87.5% (154/176) of the patients. CONCLUSION: The key to prevention of IBDI is to follow the 'identifying-cutting-identifying' principle during cholecystectomy. Re-operation time and surgical procedure are decided according to the type of IBDI. | Jin-Shu Wu Chuang Peng Xian-Hai Mao Pin Lv | 2007 | World Journal of Gastroenterology2007，13，16： | 32 |
| 2 | Assessment of Waterlogging Risk in Lixiahe Region of Jiangsu Province Based on AVHRR and MODIS Image显示文摘Four images of 1991 AVHRR, 2003 and 2007 MODIS were used to extract waterlogging inundated water of three years, and three inundated water maps were overlaid to estimate waterlogging affected frequency. Based on wa-terlogging affected frequency, waterlogging hazard of pixel scale was assessed. According to the weighed score of area percentage of different waterlogging affected frequency in 13 counties/cities of Lixiahe region, waterlogging hazard rank of every county/city was assessed. Waterlogging affected frequency map and 1km×1km grid landuse map were used to assess waterlogging risk of pixel scale; and then waterlogging risk rank of every county/city was assessed by the similar method by which waterlogging hazard rank of every county/city was assessed. High risk region is located mainly in core zone of Lixiahe hinterland, medium risk region is adjacent to high risk region, and low risk region is located in the most outlying area of risk zone and mainly in south to middle part of Lixiahe region. Xinghua and Gaoyou belong to high risk city, Jiangyan belongs to medium risk city, and the other counties/cities have low or lower waterlogging risk. The method of assessing waterlogging risk in this paper is simple and applicable. This paper can provide guidance for the waterlogging risk analysis in broader area of Huaihe River Basin. | HUANG Dapeng LIU Chuang FANG Huajun PENG Shunfeng | 2008 | Chinese Geographical Science2008，18，2： | 11 |
| 3 | Research on PCA and KPCA Self-Fusion Based MSTAR SAR Automatic Target Recognition Algorithm显示文摘This paper proposes a PCA and KPCA self-fusion based MSTAR SAR automatic target recognition algorithm. This algorithm combines the linear feature extracted from principal component analysis (PCA) and nonlinear feature extracted from kernel principal component analysis (KPCA) respectively, and then utilizes the adaptive feature fusion algorithm which is based on the weighted maximum margin criterion (WMMC) to fuse the features in order to achieve better performance. The linear regression classifier is used in the experiments. The experimental results indicate that the proposed self-fusion algorithm achieves higher recognition rate compared with the traditional PCA and KPCA feature fusion algorithms. | Chuang Lin Fei Peng Bing-Hui Wang Wei-Feng Sun Xiang-Jie Kong | 2012 | Journal of Electronic Science and Technology2012，10，4： | 6 |
| 4 | Solute-homogenization model and its experimental verification in Mg-Gd-based alloys显示文摘Composition homogenization in solid solution is important for industrial alloys. In the present work, a solute homogenization model is proposed based on the chemical short-range-order tendency in Mg-Gdbased alloys. After a calculation using the cluster-plus-glue-atom model, the stable Mg-Gd structural unit is derived, [Gd-Mg12]Mg6, where one solute Gd is nearest-neighbored with twelve Mg atoms to form the characteristic hcp cluster [Gd-Mg12] and this cluster is matched with six Mg glue atoms. Such a local unit is then mixed with [Mg-Mg12]Mg3, the stable unit for pure Mg. Assuming that the Gd-containing units are arranged in fcc-or bcc-like lattice points and the Mg units in their octahedral interstices, three proportions between the two units are obtained, 1:1, 2:3, and 1:3, which constitute three solute homogenization modes. The prevailing Mg-Gd-based alloys are consequently classified into three groups, respectively exemplified by GW103 K(Mg-10 Gd-3 Y-0.4 Zr, wt%), GW83 K(Mg-8 Gd-3 Y-0.4 Zr), and GW63 K(Mg-6 Gd-3 Y-0.4 Zr). Mg-Gd-Y-Zr alloys were designed following the model(where Y and Zr were also added in substitution for Gd) and prepared by permanent-mould casting. According to their mechanical properties,the 1:3 alloy(Mg-5.9 Gd-1.6 Y-0.4 Zr) shows the best comprehensive properties(ultimate tensile strength305 MPa, yield strength 186 MPa, elongation 9.0%) in solution plus ageing state. | Shengnan Qian Chuang Dong Tianyu Liu Ying Qin Qing Wang Yujuan Wu Lidong Gu Jianxin Zou Xiangwen Heng Liming Peng Xiaoqin Zeng | 2018 | Journal of Materials Science & Technology2018，34，7： | 6 |
| 5 | Characteristics on microstructure and mechanical performances of 6111Al influenced by Ce-containing precipitates显示文摘In this work,the effects of Ce addition(0,0.1 wt%,0.3 wt%,0.5 wt%and 0.7 wt%)on the evolution of microstructure and mechanical properties of 6111 Al alloy and strengthening mechanism of 6111 Al-Ce alloy were systematically investigated by a polarizing microscope,a scanning electronic microscope,an energy dispersive spectroscope and a high-resolution transmission electron microscope.The results indicate that with 0.3 wt%Ce addition,theα-Al grains show the equiaxed crystal morphology with the average size decreasing from 137 to 57μm and numerous small AlCeSi phases with lump-like or platelike morphology are distributed closely along the grain boundary.The peak yield strength,ultimate tensile strength and elongation of 6111 Al-Ce alloy reach to 279 MPa,316 MPa and 12.1%,respectively,which is attributed to the grain refinement strengthening and the formation of nanosized Al11Ce3 precipitates.Eventually,this investigation gives us instructive suggestion to prepare the new kind of aluminum alloy with high strength and high ductility. | Xu Gao Yutao Zhao Xizhou Kai Wei Qian Liwei Jin Chuang Guan Peng Sheng | 2022 | Journal of Rare Earths2022，40，1： | 3 |
| 6 | Performance Evaluation and Dynamic Optimization of Speed Scaling on Web Servers in Cloud Computing显示文摘The energy consumption in large-scale data centers is attracting more and more attention today with the increasing data center energy costs making the enhanced performance very expensive. This is becoming a bottleneck to further developments in terms of both scale and performance of cloud computing. Thus, the reduction of the energy consumption by data centers is becoming a key research topic in green IT and green computing. The web servers providing cloud service computing run at various speeds for different scenarios. By shifting among these states using speed scaling, the energy consumption is proportional to the workload, which is termed energy-proportionality. This study uses stochastic service decision nets to investigate energy-efficient speed scaling on web servers. This model combines stochastic Petri nets with Markov decision process models. This enables the model to dynamically optimize the speed scaling strategy and make performance evaluations. The model is graphical and intuitive enough to characterize complicated system behavior and decisions. The model is service-oriented using the typical service patterns to reduce the complex model to a simple model with a smaller state space. Performance and reward equivalent analyse substantially reduces the system behavior sub-net. The model gives the optimal strategy and evaluates performance and energy metrics more concisely. | Yuan Tian Chuang Lin Zhen Chen Jianxiong Wan Xuehai Peng | 2013 | Tsinghua Science and Technology2013，18，3： | 3 |
| 7 | Improvement of stability and solid-state battery performances of annealed 70Li_(2)S–30P_(2)S_(5) electrolytes by additives显示文摘The replacement of liquid electrolyte with solid electrolyte can significantly improve the safety and power/energy density of lithium batteries.70Li_(2)S–30P_(2)S_(5) is one of the most promising solid electrolytes with high conductivity for solid–state batteries.In this work,the ionic conductivity and stability toward moisture and lithium metal of 70Li_(2)S–30P_(2)S_(5) were enhanced by introducing the different amounts of Li_(2)O additives.65Li_(2)S–30P_(2)S_(5)–1%Li_(2)O delivered the highest conductivity,while 65Li_(2)S–30P_(2)S_(5)–5%Li_(2)O showed the best moisture stability and improved lithium compatibility.Solid-state batteries using 65Li_(2)S–30P_(2)S_(5)–5%Li_(2)O electrolyte and high-voltage LiNi_(0.6)Mn_(0.2)Co_(0.2)O_(2) cathode exhibited low initial discharge capacity(100 mAh·g^(-1))and Coulombic efficiency(69%).Li_(3)InCl_(6) electrolytes were introduced both in the cathode mixture to replace sulfide electrolyte and in the interface layer to improve the cathode compatibility for the solid-state batteries,showing enhanced discharge capacity(175 mAh·g^(-1))and improved initial Coulombic efficiency(86%).Moreover,it also exhibited good performance at-20℃. | Hao-Tian Ren Zi-Qi Zhang Jun-Zhao Zhang Lin-Feng Peng Zhen-Yuan He Ming Yu Chuang Yu Long Zhang Jia Xie Shi-Jie Cheng | 2022 | Rare Metals2022，41，1： | 3 |
| 8 | Simultaneous evaluation of two branches of a multifunctional integrated optic chip with an ultra-simple dual-channel configuration显示文摘We propose an ultra-simple dual-channel configuration for simultaneously evaluating two branches of a multifunctional integrated optic chip(MFIOC). In the configuration, the MFIOC is employed as a beam splitter to construct the demodulation interferometer together with a 2 × 2 fiber coupler. Interference happens between polarization modes traveling through different channels of the MFIOC. The cross-couplings of each channel are respectively characterized by the interference peaks which distribute on opposite sides of the central interference peak. Temperature responses of the MFIOC are experimentally measured from-40°C to 80°C. Results show that the proposed configuration can achieve simultaneous dual-channel transient measurements with resolution of-90 d B and dynamic range of 90 d B. In addition, the two channels of the configuration have consistent measuring performance, and the two branches of the MFIOC have different responses to temperature variation. | Yonggui Yuan Chuang Li Jun Yang Ai Zhou Shuai Liang Zhangjun Yu Bing Wu Feng Peng Yu Zhang Zhihai Liu Libo Yuan | 2015 | Photonics Research2015，3，4： | 2 |
| 9 | Human umbilical cord mesenchymal stem cells for psoriasis:a phase 1/2a,single-arm study显示文摘Psoriasis is a common,chronic immune-mediated systemic disease that had no effective and durable treatment.Mesenchymal stem cells(MSCs)have immunomodulatory properties.Therefore,we performed a phase 1/2a,single-arm clinical trial to evaluate the safety and efficacy of human umbilical cord-derived MSCs(UMSCs)in the treatment of psoriasis and to preliminarily explore the possible mechanisms.Seventeen patients with psoriasis were enrolled and received UMsC infusions.Adverse events,laboratory parameters,PASl,and PGA were analyzed.We did not observe obvious side effects during the treatment and 6-month follow-up.A total of 47.1%(8/17)of the psoriasis patients had at least 40%improvement in the PASl score,and 17.6%(3/17)had no sign of disease or minimal disease based on the PGA score.And the efficiency was 25%(2/8)for males and 66.7%(6/9)for females.After UMSC transplantation(UMSCT),the frequencies of Tregs and CD4^(+)memory T cells were significantly increased,and the frequencies of T helper(Th)17 and CD4^(+)naive T cells were significantly decreased in peripheral blood(PB)of psoriasis patients.And all responders showed significant increases in Tregs and CD4^(+)memory T cells,and significant decreases in Th17 cells and serum IL-17 level after UMsCT.And baseline level of Tregs in responders were significantly lower than those in nonresponders.In conclusion,allogeneic UMSCT is safe and partially effective in psoriasis patients,and level of Tregs may be used as a potent biomarker to predict the clinical efficacy of UMSCT.Trial registration Clinical Trials NCT03765957. | Lamei Cheng Siqi Wang Cong Peng Xiao Zou Chao Yang Hua Mei Chuang Li Xian Su Na Xiao Qi Ouyang Mi Zhang Qiaolin Wang Yan Luo Minxue Shen Qun Qin Honglin Wang Wu Zhu Guangxiu Lu Ge Lin Yehong Kuang Xiang Chen | 2022 | Signal Transduction and Targeted Therapy2022，7，9： | 2 |
