| 8 | Binding Activity Difference of Anti-CD20 scFv-Fc Fusion Protein Derived from Variable Domain Exchange显示文摘Two novel engineered antibody fragments binding to antigen CD20 were generated by fusing a murine IgM-type anti-CD20 single-chain Fv fragment (scFv) to the human IgG1 CH2 (i.e., Cγ2) and CH3 (i.e., Cγ3) domains with the human IgG1 hinge (i.e. Hγ). Given the relationship between structure and function of protein, the 3-D structures of the two engineered antibody fragments were modeled using computer-aided homology modeling method. Furthermore, the relationship between 3-D conformation and their binding activity was evaluated theoretically. Due to the change of active pocket formed by CDRs, the HL23 (VH-Linker-VL-Hγ-Cγ2-Cγ3) remained its activity because of its preserved conformation, while the binding activity of the LH23 (VL-Linker-VH-Hγ-Cγ2-Cγ3) was impaired severely. Experimental studies by flow cytometry and fluorescence microscopy showed that HL23 possessed significantly superior binding activity to CD20-expressing target cells than LH23. That is to say, the order of variable regions could influence the binding activity of the fusion protein to CD20+ cell lines, which was in accordance with the theoretical results. The study highlights the potential relationship between the antibody binding activity and their 3-D conformation, which appears to be worthwhile in providing direction for future antibody design of recombinant antibody. | Shusheng Geng Jiannan Feng Yan Li Yingxun Sun Xin Gu Ying Huang Yugang Wang Xianjiang Kang Hong Chang Beifen Shen | 2006 | Cellular & Molecular Immunology2006，3，6： | 13 |

| 11 | Changing Proportions of HIV-1 Subtypes and Transmitted Drug Resistance Among Newly Diagnosed HIV/AIDS Individuals—China,2015 and 2018显示文摘Introduction:With the expansion of human immunodeficiency virus(HIV)antiretroviral therapy(ART),HIV drug resistance is becoming more and more serious.This study describes the changing prevalence of HIV-1 subtypes and transmitted drug resistance(TDR)among newly diagnosed individuals in China,2015 and 2018.Methods:A total of 8,980 individuals in 2015 and 2018 from 31 provincial-level administrative divisions(PLADs)were enrolled in this study.Viral RNAs were amplified and sequenced using an in-house polymerase chain reaction(PCR)protocol.The Stanford HIV Drug Resistance Database(HIVdb)was used to predict susceptibility to 12 antiretroviral drugs.Results:The prevalence of TDR was not significantly increased over time.The prevalence of TDR was 3.8%and 4.4%in 2015 and 2018,respectively(P=0.13).The prevalence of CRF55_01B increased from 2.3%in 2015 to 3.9%in 2018(P<0.001).The drug resistance prevalence of nonnucleoside reverse transcriptase inhibitors(NNRTI)increased from 2.4%in 2015 to 3.3%in 2018(P<0.01).The prevalence of E138(P<0.001),H221(P=0.03),and V179(P<0.001)mutations increased from 0.30%,0.09%,and 0.70%in 2015 to 1.10%,0.30%,and 1.70%in 2018,respectively.Conclusions:HIV drug resistance affects the effect of antiretroviral treatment,so the monitoring of HIV TDR should be strengthened to control the transmission of HIV drug resistance. | Jingjing Hao Shan Zheng Mengze Gan Aobo Dong Ruihua Kang Miaomiao Li Shuai Zhao Jing Hu Chang Song Lingjie Liao Yi Feng Yiming Shao Yuhua Ruan Hui Xing | 2021 | China CDC weekly2021，3，53： | 13 |
| 12 | Three-Dimensional Thermo-mechanical Coupled FEM Simulation for Hot Continuous Rolling of Large-Diameter Mandrel Bar显示文摘Based on the important boundary conditions of rolling simulation including friction, heat conduction and interactionsof the workpiece and rolls, the hot continuous rolling processes of large-diameter mandrel round bar (200 mm indiameter) in 6VH-stand hot tandem mill are successfully simulated by three-dimensional coupled thermomechanicalelastoplastic finite element method (FEM). The distributions of stress, strain, temperature and the rolling force andtorque for the two-pass and four-pass continuous rolling are calculated respectively. Thus, the two and four-passroll schedules are verified, respectively. The simulation results show that it is safe to produce 200 mm round barby the two-pass (oval pass and round pass) continuous rolling on the existing equipment compared to the four-passcontinuous rolling. There are concave surfaces and increased widths occurring at the end of rolled billet due touneven deformations between the outside and inside of the workpiece as well as the free spreading close to the rollgap of the final pass. | Huiping HONG Yonglin KANG Changtao FENG Xiqiang CHEN | 2003 | Journal of Materials Science & Technology2003，19，z1： | 13 |

| 14 | Esophagojejunostomy after laparoscopic total gastrectomy by Or VilTM or hemi-double stapling technique显示文摘AIM: To investigate the feasibility, advantages and disadvantages of two types of anvil insertion techniques for esophagojejunostomy after laparoscopic total gastrectomy.METHODS: This was an open-label prospective cohort study. Laparoscopy-assisted radical total gastrectomy with D2 lymph node dissection was performed in 84 patients with primary non-metastatic gastric cancer confirmed by pre-operative histological examination. Overweight patients were excluded, as well as patients with peritoneal dissemination and invasion of adjacent organs. After total gastrectomy, all patients were randomized into two groups. Patients in Group Ⅰ underwent esophagojejunostomy using a transorally-inserted anvil(Or VilTM), while patients in Group Ⅱ underwent esophagojejunostomy using the hemi-double stapling technique(HDST). Both types of esophagojejunostomy were performed under laparoscopy. Patients' baseline characteristics, preoperative characteristics, perioperative characteristics, short-term postoperative outcomes and operation cost were comparedbetween the two groups. The primary endpoint was evaluation of the surgical outcome(operating time, time of digestive tract reconstruction and time of anvil insertion) and the medical cost of each operation(operation cost and total cost of hospitalization). The secondary endpoints were time to solid diet, post-surgical hospitalization time, time to defecation, time to ambulation and intra-operative blood loss. In addition, complications were assessed and compared. RESULTS: Laparoscopic total gastrectomy and esophagojejunostomy were successfully performed in all 84 patients, without conversion to laparotomy. There were no significant differences in the operative time and time for total gastrectomy between the two groups(287.8 ± 38.4 min vs 271.8 ± 46.1 min, P = 0.09, and 147.7 ± 31.6 min vs 159.8 ± 33.8 min, P = 0.09, respectively). The time for digestive tract reconstruction and for anvil insertion were significantly decreased in Group Ⅱ compared with Group I(47.8 ± 12.1 min vs 55.4 ± 15.7 min, P = 0.01, and 12.6 ± 4.7 min vs 18.7 ± 7.5 min, P = 0.001, respectively). Intraoperative blood loss(96.4 ± 32.7 m L vs 88.2 ± 36.9 m L, P = 0.28), time to defecation(3.5 ± 0.9 d vs 3.2 ± 1.1 d, P = 0.12), time to ambulation(3.9 ± 0.7 d vs 3.6 ± 1.1 d, P = 0.12), time to solid diet(7.6 ± 1.4 d vs 8.0 ± 2.7 d, P = 0.31) and total hospitalization(10.6 ± 2.6 d vs 10.8 ± 3.5 d, P = 0.80) were similar between the two groups. In addition, the total costs of hospitalization were similar between the two groups(73848.7 ± 11781.0 RMB vs 70870.3 ± 14003.5 RMB, P = 0.296), but operation cost was significantly higher in Group I compared with Group Ⅱ(32401.9 ± 1981.6 RMB vs 26961.9 ± 2293.8 RMB, P < 0.001).CONCLUSION: Anvil insertion was faster and easier using the HDST technique compared with Or VilTM, and was more cost-effective. There was no significant difference in safety. | Hao Wang Qun Hao Meng Wang Min Feng Feng Wang Xin Kang Wen-Xian Guan | 2015 | World Journal of Gastroenterology2015，21，29： | 12 |
| 15 | Plant Polyploidy: Origin, Evolution, and Its Influence on Crop Domestication显示文摘The prevalence and recurrence of polyploidization in plant species make it one of the most important evolutionary events in plants, and as a result, polyploidization is an extensively investigated research field. Due to the rapid development of sequencing technologies, there is increased evidence to support that polyploidization plays an important role in the diversification of plant species, evolution of genes, and the domestication of crops. Here, we reviewed the influence of polyploidization on various aspects of plant evolution, mainly focused on polyploid origin, characteristics, subsequent genome divergence, and its impact on gene function innovation and crop domestication. The occurrence of many independent polyploidization events in plants was found to be tightly associated with the timing of extreme climate events or natural disasters on earth, leading to mass extinction while possibly facilitating increased polyploidization. Following allo-polyploidization, a distinct phenomenon known as sub-genome dominance occurred during sub-genome evolution, which was found to be associated with the methylation of transposons. Extensive gene fractionations(lost) following polyploidization were reported in almost all paleo-polyploids, and the evolutionary fates of multi-copy genes, such as sub-/neo-functionalization, were further proposed to illustrate their underlying mechanisms. Moreover,polyploidization was found to significantly impact species diversification, with subsequent effects on crop domestication and the development of traits with agronomic importance. Based on the progress of plant polyploidization studies, we discussed several main topics that might further improve our understanding of polyploid evolution and that are likely contribute to the application of polyploidization in crop breeding in the near future. | Kang Zhang Xiaowu Wang Feng Cheng | 2019 | Horticultural Plant Journal2019，5，6： | 12 |

| 17 | Characteristics of the crustal magnetic anomaly and regional tectonics in the Qinghai-Tibet Plateau and the adjacent areas显示文摘Study of the characteristics of the crustal magnetic anomaly in the Qinghai-Tibet Plateau and the adjacent areas helps better understand the lithospheric structure and evolution, as well as the regional geodynamic processes. Here we analyze the distribution laws of the crustal magnetic anomaly and its vertical gradient, the decay characteristics of the anomaly, the contributions from different wavelength bands to the anomaly, and the relationship between the anomaly and the crustal regional tectonics in the plateau and nearby, based on a new and higher degree geomagnetic model NGDC-EMM-720-V3 constructed from the surface, aeromagnetic, marine and satellite survey data. The results reveal that the positive and negative anomalies in the Qinghai-Tibet Plateau are weak, while those of the surrounding areas are strong. The boundary agrees well with the border of the plateau regional tectonics. The anomaly is nearly east-west in the central and western plateau, arc-shaped in the southwestern and eastern, and nearly north-south in the southeastern, consistent with the tectonic trends. There are strong negative anomaly foci in the east and west syntaxis, whereas no significant differences exist among the Cenozoic blocks in the plateau interior. No direct correspondence exists between the anomaly and the crustal depth. On the background of a weak magnetic anomaly in the plateau, relatively stronger short wavelength fields from the shallower crust are overlapped in the Lhasa, Qilian, Qaidam, and Sichuan-Yunnan rhombic blocks. A strong negative anomaly in the east-west direction is distributed along the Himalayas, mainly caused by the middle and long wavelength bands in the deep and central crust. The magnetic structural layers are stable in the Sichuan and Tarim basins. The anomalies at different altitudes over the southern plateau vary strongly, showing a drastic variation in the magnetic structure from the deep crust to the shallow crust. | KANG GuoFa GAO GuoMing BAI ChunHua SHAO Dan FENG LiLi | 2012 | Science China Earth Sciences2012，55，6： | 11 |

| 20 | Spatial and temporal variation of haze in China from 1961 to 2012显示文摘The purpose of this study is to analyze the climatic characteristics and long-term spatial and temporal variations of haze occurrence in China. The impact factors of haze trends are also discussed. Meteorological data from 1961 to 2012 and daily PM10 concentrations from2003 to 2012 were employed in this study. The results indicate that the annual-average hazy days at all stations have been increasing rapidly from 4 days in 1961 to 18 days in 2012. The maximum number of haze days occur in winter(41.1%) while the minimum occur in summer(10.4%). During 1961-2012, the high occurrence areas of haze shifted from central to south and east regions of China. The Beijing-Tianjin-Hebei(Jing-Jin-Ji) region, Shanxi,Shaanxi, and Henan Province are the high occurrence areas for haze, while the Yangtze River Delta(YRD) and the Pearl River Delta(PRD) have become regions with high haze occurrences in the last 25 years. Temperature and pressure are positively correlated with the number of haze days. However, wind, relative humidity, precipitation, and sunshine duration are negatively correlated with the number of haze days. The key meteorological factors affecting the formation and dissipation of haze vary for high and low altitudes, and are closely related to anthropogenic activities. In recent years, anthropogenic activities have played a more important role in haze occurrences compared with meteorological factors. | Rui Han Shuxiao Wang Wenhai Shen Jiandong Wang Kang Wu Zhihua Ren Mingnong Feng | 2016 | Journal of Environmental Sciences2016，28，8： | 11 |
