| 1 | Critical slope gradient for compulsory abandonment of farmland on the hilly Loess Plateau显示文摘Scientific evidence for the upper limit of farmland is proposed. Shallow gully erosion is one of erosion types distributed extensively on sloping farmland in the hilly regions of the Loess Plateau. Field observation and aerial photos interpretation, as well as laboratory experiments show that the shallow gully erosion occurring on the steeper farmland in the hilly regions of the Loess Plateau is an important factor leading to intensive erosion on slope, because of its extensive distribution and intensive runoff collection. The data on the formation, development and distribution of shallow gullies on sloping farmland indicate that critical slope gradient for shallow gully initiation ranges from 15 to 20 degrees with an average of 18.2 degrees. Therefore, it is suggested that critical slope gradient for compulsory abandonment of farmland on the hilly Loess Plateau should be kept within the critical slope gradient for shallow gully initiation to prevent shallow gully formation in order to control soil loss more effectively. But as the first step, the cultivation on the slopes with slope larger than 25 degrees where the maximum erosion occurs should be strictly forbidden. | TANG Keli+1, ZHANG Keli 1,2 and LEI Aling 1,3 1.

| 2 | Nicotine-induced upregulation of antioxidant protein Prx 1 in oral squamous cell carcinoma显示文摘Nicotine is a source of exogenous oxidative stress, which is associated with the pathogenesis of numerous diseases including oral squamous cell carcinoma (OSCC), whereas an antioxidant protein, peroxiredoxin 1 (Prx 1), plays an important role in the modulation of this condition. This study was to investigate the association between Prx 1 and tobacco-induced oxidative stress. The expression of Prx 1 and GST in OSCC Tca8113 cells, which were pre-treated with nicotine, was determined. In the present study, MTT assay, reactive oxygen species (ROS) assay, RT-PCR and Western blot analyses, respectively, were conducted to assess cell viability, ROS level, and expression level of Prx 1 and GST in nicotine-treated Tca8113 cells. Nuclear factor kappa B (NF- B) expression was detected by immuno-fluorescence. Our results showed the growth of Tca8113 cells was increased in a dose-dependent manner when cells were treated with nicotine at concentrations from 0.1 to 10 mol/L, but the proliferation of the cells decreased at 100 mol/L. ROS levels increased in all groups treated with nicotine at concentrations of 0.1, 1, 10, or 100 mol/L for 24h. Prx 1 and GST mRNA and protein expression were up-regulated in cells treated with nicotine for the same time at different concentrations or at the same concentration for different times (P<0.05). NF-B was translocated from cytoplasm to nucleus, the expression of NF- B was increased in nucleus. These results suggest that up-regulation of Prx1 expression appears to be associated with tobacco-induced oxidative stress, which may play an important role in the pathogenesis of OSCC. | ZHAO YanHua ZHANG Min YAN Fei CASTO Bruce C TANG XiaoFei | 2013 | Chinese Science Bulletin2013,58,16: | 7 |
| 3 | Effective Hybrid Teaching-learning-based Optimization Algorithm for Balancing Two-sided Assembly Lines with Multiple Constraints显示文摘Due to the NP-hardness of the two-sided assembly line balancing(TALB) problem, multiple constraints existing in real applications are less studied, especially when one task is involved with several constraints. In this paper, an effective hybrid algorithm is proposed to address the TALB problem with multiple constraints(TALB-MC). Considering the discrete attribute of TALB-MC and the continuous attribute of the standard teaching-learning-based optimization(TLBO) algorithm, the random-keys method is hired in task permutation representation, for the purpose of bridging the gap between them. Subsequently, a special mechanism for handling multiple constraints is developed. In the mechanism, the directions constraint of each task is ensured by the direction check and adjustment. The zoning constraints and the synchronism constraints are satisfied by teasing out the hidden correlations among constraints. The positional constraint is allowed to be violated to some extent in decoding and punished in cost function. Finally, with the TLBO seeking for the global optimum, the variable neighborhood search(VNS) is further hybridized to extend the local search space. The experimental results show that the proposed hybrid algorithm outperforms the late acceptance hill-climbing algorithm(LAHC) for TALB-MC in most cases, especially for large-size problems with multiple constraints, and demonstrates well balance between the exploration and the exploitation. This research proposes an effective and efficient algorithm for solving TALB-MC problem by hybridizing the TLBO and VNS. | TANG Qiuhua LI Zixiang ZHANG Liping FLOUDAS C A CAO Xiaojun | 2015 | Chinese Journal of Mechanical Engineering2015,28,5: | 7 |

| 13 | Complementary roles of interventional radiology and therapeutic endoscopy in gastroenterology显示文摘Acute upper and lower gastrointestinal bleeding, enteral feeding, cecostomy tubes and luminal strictures are some of the common reasons for gastroenterology service. While surgery was initially considered the main treatment modality, the advent of both therapeutic endoscopy and interventional radiology have resulted in the paradigm shift in the management of these conditions. In this paper, we discuss the patient's work up, indications, and complementary roles of endoscopic and angiographic management in the settings of gastrointestinal bleeding, enteral feeding, cecostomy tube placement and luminal strictures. These conditions often require multidisciplinary approaches involving a team of interventional radiologists, gastroenterologists and surgeons. Further, the authors also aim to describe how the fields of interventional radiology and gastrointestinal endoscopy are overlapping and complementary in the management of these complex conditions. | David M Ray Indu Srinivasan Shou-jiang Tang Andreas S Vilmann Peter Vilmann Timothy C McCowan Akash M Patel | 2017 | World Journal of Radiology2017,9,3: | 2 |
