| 5 | Dynamics of Saline-alkali Land and Its Ecological Regionalization in Western Songnen Plain, China显示文摘As the important reserve land resources for food production,saline-alkali land should play a significant role to ensure the national food security in the context of global food crisis. The western Songnen Plain is one of main distribution regions of saline-alkali land in China,with great potential in agricultural development. In this study,the extent,transformation,spatial distribution and temporal change of saline-alkali land in the western Songnen Plain during 1954–2005 were investigated by using remote sensing and GIS spatial analysis methods. Saline-alkali land change was detected from a temporal series of topographic maps in 1954,satellite images of Landsat MSS in 1976,Landsat TM/ETM in 1988,2000 and 2005 through artificial visual interpretation. The results indicated a significant expansion in saline-alkali land area and aggravation in salinization. The area of saline-alkali land had increased from 401.48×103 ha in 1954 to 1 097.45×103 ha in 2005. While the ratio of light,moderate and serious salinized land areas changed from 6.72︰2.92︰1.00 to 1.25︰1.06︰1.00 in the study period. Grassland,cropland,swampland and water body were the major land use and land cover types from which saline-alkali land transformed. And the secondary salinization occured mainly in Da′an City,Tongyu County,Changling County,Daqing City,Dorbod Mongolian Autonomous County and Zhaoyuan County. Finally,seven large ecoregions and 14 corresponding sub-ecoregions were delineated out based on spatio-temopral dynamic characteristics of saline-alkali land and geo-relational environmental attributes. According to the results,measures of amelioration and ways of development of saline-alkali land in the western Songnen Plain were put forward. | YANG Jiuchun ZHANG Shuwen LI Ying BU Kun ZHANG Yubo CHANG Liping ZHANG Yangzhen | 2010 | Chinese Geographical Science2010，20，2： | 17 |
| 6 | Infantile hepatic hemangioendothelioma:A clinicopathologic study in a Chinese population显示文摘AIM:To investigate whether the clinicopathologic features of infantile hemangioendothelioma(IHE) of the liver in a Chinese population are similar to the features observed in other races.METHODS:The clinical data,radiological findings,histopathological changes and outcome of 12 cases of IHE diagnosed by the Department of Pathology,West China Hospital over the last 10 years were analyzed retrospectively.Immunohistochemical studies were carried out using antibodies against CD31,CD34,Factor Ⅷ,cytokeratin 8 and cytokeratin 18.RESULTS:The 12 patients were aged from fetal to 5 years(three males and nine females).The tumor was presented with different clinical manifestations,mainly as an asymptomatic,palpable,upper abdominal mass,except for the two fetuses who were detected antena-tally by ultrasound.In one patient,this presentation was accompanied by an initial severe pneumothorax.No symptoms of congestive heart failure were present and neither congenital abnormalities nor vascular tumors in the skin or other organs were found.Laboratory abnormalities included leukocytosis(40%),anemia(60%),thrombocytosis(60%),hyperbilirubinemia(16.7%),abnormal liver function(50%) and increased α-fetoprotein(80%).Based on radiological findings and gross specimens,the tumor presented as a solitary lesion or a multifocal space-occupying lesion.The tumor size ranged from 5.0 cm × 3.5 cm × 2.0 cm to 13.8 cm × 9.0 cm × 7.7 cm,and the 0.2-1.1 cm nodules were diffusely distributed within the multifocal tumor.Seven cases were surgically resected,three cases underwent biopsy and the two fetuses were aborted.Histologically,nine cases were classified as typeⅠ and three as type Ⅱ,presenting aggressive morphologic features,immature vessels,active mitosis and necrosis.An inflammatory component,predominantly eosinophilic granulocytes,sometimes obscured the nature of the tumor.Ten patients are alive after a follow-up of 1-9 years.Based on immunohistochemistry,the endothelial cells in all cases were positive for CD31,CD34 and polyclonal factor Ⅷ antigen,whereas the scattered hyperplasia bile ducts were positive for cytokeratin 8 and cytokeratin 18.CONCLUSION:The clinical manifestations of IHE are non-specific.There is no significant correlation between histological type and prognosis.The clinicopathologic features of IHE in Chinese patients may provide a clue to further evidence-based studies. | Zhang Zhang,Hui-Jiao Chen,Wen-Juan Yang,Hong Bu,Bing Wei,Xiao-Yu Long,Jing Fu,Rui Zhang,Yun-Bi Ni,Hong-Ying Zhang,Department of Pathology,West China Hospital,Sichuan University,Guoxuexiang 37,Chengdu 610041,Sichuan Province,China | 2010 | World Journal of Gastroenterology2010，16，36： | 16 |

| 8 | Effects of physical soil crusts on infiltration and splash erosion in three typical Chinese soils显示文摘Physical soil crusts likely have significant effects on infiltration and soil erosion,however,little is known on whether the effects of the crusts change during a rainfall event.Further,there is a lack of discussions on the differences among the crusting effects of different soil types.The objectives of this study are as follows:(i) to study the effects of soil crusts on infiltration,runoff,and splash erosion using three typical soils in China,(ii) to distinguish the different effects on hydrology and erosion of the three soils and discuss the primary reasons for these differences,and(iii) to understand the variations in real soil shear strength of the three soils during rainfall events and mathematically model the effects of the crusts on soil erosion.This study showed that the soil crusts delayed the onset of infiltration by 5 to 15 min and reduced the total amount of infiltration by 42.9 to 53.4%during rainfall events.For a purple soil and a loess soil,the initial crust increased the runoff by 2.8%and 3.4%,respectively,and reduced the splash erosion by 3.1%and 8.9%,respectively.For a black soil,the soil crust increased the runoff by 42.9%and unexpectedly increased the splash erosion by 95.2%.In general,the effects of crusts on the purple and loess soils were similar and negligible,but the effects were significant for the black soil.The soil shear strength decreased dynamically and gradually during the rainfall events,and the values of crusted soils were higher than those of incrusted soils,especially during the early stage of the rainfall.Mathematical models were developed to describe the effects of soil crusts on the splash erosion for the three soils as follows:purple soil,F_c =0.002?-0.384;black soil,F_c =-0.022?+ 3.060;and loess soil,F_c.= 0.233lnt-1.239.Combined with the equation R_c =F_c·(R_(uc)-1).the splash erosion of the crusted soil can be predicted over time. | Chong-feng BU Shu-fang WU Kai-bao YANG | 2014 | International Journal of Sediment Research2014，29，4： | 12 |
| 9 | Effects of metabolizable energy and crude protein levels on laying performance,egg quality and serum biochemical indices of Fengda-1 layers显示文摘This study was conducted to investigate the effects of dietary ME and CP levels on laying performance, egg quality and serum biochemical indices of Fengda-1 layers. In a 2 × 3 factorial arrangement, 2,400 Fengda-1 layers(32 wk of age) were randomly assigned to 6 experimental diets with 2,650 and 2,750 kcal of ME/kg of diet, each containing 14.50%, 15.00% and 15.50% CP, respectively. Each dietary treatment was replicated 5 times, and feed and water were provided ad libitum. The trial lasted for 10 wk, including a2-week acclimation period and an 8-week experimental period. Our results showed that ADFI decreased as the ME level of diet increased from 2,650 to 2,750 kcal/kg(P< 0.05). Layers fed diets with 2,750 kcal/kg ME exhibited higher mortality than those fed with 2,650 kcal/kg ME(P < 0.05). Birds fed with 14.50% and15.00% CP had higher egg production(EP) and egg mass(EM) than those fed with 15.50% CP(P < 0.05).Yolk color increased as the ME level of the diet increased from 2,650 to 2,750 kcal/kg, however, the eggshell thickness decreased(P < 0.05). Serum concentrations of uric acid and triglyceride in layers fed diets with 2,750 kcal/kg ME were higher than those fed diets with 2,650 kcal/kg ME(P < 0.05). There was no significant interaction between ME and CP on laying performance, egg quality, or serum biochemical indices(P > 0.05). Based on the data under the experimental conditions, the optimal dietary ME and CP levels of Fengda-1 layers are 2,650 kcal/kg and 15.00%(33 to 41 wk of age). | Yang Ding Xingchen Bu Nannan Zhang Lanlan Li Xiaoting Zou | 2016 | Animal Nutrition2016，，2： | 11 |

| 11 | Traditional Chinese medicine as supportive care for the management of liver cancer: Past, present, and future显示文摘Liver cancer is the sixth most commonly diagnosed cancer and the fourth leading cause of cancer death worldwide.Western medicine and therapies are the primary treatment strategies of hepatocellular carcinoma(HCC),but the general prognosis for HCC patients is still dismal.Under these circumstances,HCC prevention is particularly important.Traditional Chinese medicine(TCM)encompasses a wealth of documented therapeutic resources,and“preventative treatment”is the principle of TCM.In China,TCM has been used for HCC prevention for thousands of years,and has also been demonstrated to be effective for the treatment of HCC in modern China.However,the TCM theory for prevention and treatment of HCC is more widely accepted in China than abroad.In this review,we first summarize the herbs and ancient formulas with therapeutic effects on HCC.We also review the research status of TCM in modern medicine as well as the current obstacles in its development.Finally,we discuss the future of TCM in the context of precision and integrated medicine.After reviewing the literature,we believe that TCM,through ancient development,is an advanced method of cancer treatment with positive curative effects,despite its surrounding controversy.Furthermore,precise analyses and systematic research methods provides novel approaches to modernize TCM for the future. | Xia Liao Yang Bu Qingan Jia | 2020 | Genes & Diseases2020，7，3： | 11 |
| 12 | Remote Sensing Monitoring of Gullies on a Regional Scale: A Case Study of Kebai Region in Heilongjiang Province, China显示文摘Gully erosion is one of the major causes of land degradation in most areas and attracts increasing attention from researchers. We monitored gullies in the Kebai region in Heilongjiang Province of China by using remote sensing data and found that gully density increased with the increase in slope when the slope was less than 3°. Gully density in sunny slopes or windward slopes was greater than in shady slopes or leeward slopes because of the impacts of freezing and thawing, wind and solar radiation. Specifically, the gully density in northeast slope was the greatest and in southwest was the smallest. Gully density was reduced with increasing slope length and the longer the slope length, the less the gully density changed between 1965 and 2005. Affected by runoff, gullies most easily to occur in concave slopes and the critical elevation for gully erosion was 250–275 m. Moreover, hilly regions had the greatest gully density, followed by tableland regions, whereas the gully density in flatlands was the lowest. However, the gully density of these three types of landforms all increased between 1945 and 2000, and the portion of increase was 57.45%(hill), 52.91%(mesa) and 25.32%(plain), respectively. | ZHANG Shuwen LI Fei LI Tianqi YANG Jiuchun BU Kun CHANG Liping WANG Wenjuan YAN Yechao | 2015 | Chinese Geographical Science2015，25，5： | 10 |

| 15 | Comorbidity Burden of Dementia:A Hospital-Based Retrospective Study from 2003 to 2012 in Seven Cities in China显示文摘Dementia is increasing dramatically and imposes a huge burden on society. To date, there is a lack of data on the health status of patients with dementia in China. In an attempt to investigate the comorbidity burden of dementia patients in China at the national level, we enrolled 2,938 patients with Alzheimer's disease(AD), vascular dementia(Va D), or other types of dementia, who were admitted to tertiary hospitals in seven regions of China from January2003 to December 2012. The Charlson Comorbidity Index(CCI) was used to evaluate the comorbidity burden of the patients with dementia. Among these patients, 53.4% had AD, 26.3% had Va D, and 20.3% had other types of dementia. The CCI was 3.0 ± 1.9 for all patients,3.4 ± 1.8 for those with Va D, and 3.0 ± 2.1 for those with AD. The CCI increased with age in all patients, andthe length of hospital stay and daily expenses rose with age and CCI. Males had a higher CCI and a longer stay than females. Moreover, patients admitted in the last 5 years of the study had a higher CCI than those admitted in the first 5 years. We found that the comorbidity burden of patients with dementia is heavy. These findings provide a better understanding of the overall health status of dementia patients, and help to increase the awareness of clinicians and policy-makers to improve medical care for patients. | Qing-Hua Wang Xin Wang Xian-Le Bu Yan Lian Yang Xiang Hong-Bo Luo Hai-Qiang Zou Jie Pu Zhong-He Zhou Xiao-Ping Cui Qing-Song Wang Xiang-Qun Shi Wei Han Qiang Wu Hui-Sheng Chen Hang Lin Chang-Yue Gao Li-Li Zhang Zhi-Qiang Xu Meng Zhang Hua-Dong Zhou Yan-Jiang Wang | 2017 | Neuroscience Bulletin2017，33，6： | 10 |

| 17 | Mori Cortex extract ameliorates nonalcoholic fatty liver disease( NAFLD) and insulin resistance in high-fat-diet/streptozotocininduced type 2 diabetes in rats显示文摘Nonalcoholic fatty liver disease(NAFLD) and type 2 Diabetes Mellitus(T2 DM) are highly prevalent diseases and are closely associated, with NAFLD being present in the majority of T2 DM patients. In Asian traditional medicine, Mori Cortex is widely used for the treatment of diabetes and hyperlipidemia. However, whether it has a therapeutic effect on T2 DM associated with NAFLD is still unknown. The present study showed that the oral treatment with Mori Cortex extract(MCE; 10 g·kg-1·d-1) lowered the blood lipid levels and reversed insulin resistance(IR) in high fat-diet/streptozotocin-induced type 2 diabetes in rats. The expression levels of sterol receptor element-binding protein-1 c(SREBP-1 c) and carbohydrate-responsive element binding protein(Ch REBP), which are involved in steatosis in NAFLD rats, were measured in the liver samples. MCE decreased the protein and m RNA expression levels of SREBP-1 c and Ch REBP. In conclusion, down-regulation of SREBP-1 c and Ch REBP might contribute to the protective effect of MCE on hepatic injury and IR in the rats with T2 DM associated with NAFLD. | MA Li-Li YUAN Yan-Yan ZHAO Ming ZHOU Xin-Rong Tashina Jehangir WANG Fu-Yan XI Yang BU Shi-Zhong | 2018 | Chinese Journal of Natural Medicines2018，16，6： | 9 |
| 18 | Clinicopathological, immunohistochemical, and ultrastructural study of 13 cases of melanotic schwannoma显示文摘Background Melanotic schwannoma is a rare variant of schwannoma composed of melanin-producing cellswith ultrastructural features of schwann cells.The description of the course of the tumors differs somewhat, but itis generally considered as a benign lesion.We investigated the clinicopathologic features, immunophenotypes,and ultrastructural features of 13 patients with nonpsammomatous melanotic schwannoma (NPMS).Methods Tumor specimens of each patient were sectioned and stained with hematoxylin-eosin, Fontana-Masson, Prussian blue, and periodic acid-Schiff (PAS).Immunohistochemical markers such as S-100, Leu-7,HMB-45, Melan-A, CK, EMA, vimentin, GFAP, laminin, collagenⅣ and MIB-1 were detected with theEnvision immunohistochemical staining method.Four of the cases were observed by electron microscopy.Results Of the 13 patients, 8 were male and 5 female, aged from 11 to 92 years (mean, 38.6 years).Thetumor sites included the spinal nerve root (5 patients), cranial nerve (1), greater omentum (1), subcutaneoustissue (3), mesentery (1), bone (1) and mediastinum(1).Eleven patients were followed up for over2 years,with a mean of 5.9 years.One patient (9.1%) with a primary tumor in the greater omentum developed anotherprimary tumor of the same type in the subcutaneous tissue of the abdominal wall after the first operation.Localrecurrence of the tumor was seen in2 patients (18.2%).One patient (9.1%) showed the local recurrence andmetastasis.Seven patients (63.6%) showed no evidence of the recurrence or metastasis.Grossly, all tumorswere well-circumscribed and the gross findings were suggestive of melanin-containing tumors.The tumor wascomposed of spindled and epithelioid cells with abundant intracytoplasmic melanin pigments.Nuclei were roundand contained delicate, evenly distributed chromatins as well as small, distinct nucleoli.In some areas, thenucleoli were large and prominent.Rare mitoses were seen in mostlesions exceptthe larger omentumlesion.Thepigment was shown to be positive for the Fontana-Masson and negative for Prussian blue and PAS.Immunohistochemical staining for S-100, Leu-7, HMB-45, Melan-A, and vimentin were strongly positive.Linear immunoreactions of both laminin and collagenⅣ was detected in all patients.Ultrastructurally, numerouselongated tumor-cell processes, duplicated basement membrane and melanosomes were observed in alldevelopmental stages.Conclusions Histologically, melanotic schwannoma is a rare variant of schwannoma composed of melanin-producing cells with ultrastructural features ofschwann cells.Distinguishing between this tumor andmalignant melanoma is of paramount importance inplanning of management. Immunohistochemically,combined use of laminin and collagenⅣ is valuablein distinguishing melanotic schwannoma frommalignant melanoma. Wide local resection andadditional radiotherapy should be advocated.Furtherstudies including cytogenetic or molecular biology arestill required to better delineate melanoticschwannoma from malignant melanoma. Appropriate long-term follow-up is needed for all melanoticschwannomas. | ZHANG Hong-ying YANG Guang-hua CHEN Hui-jiao WEI Bing KE Qi GUO Hua YE Lü BU Hong YANG Ke ZHANG Yuan-heng | 2005 | Chinese Medical Journal2005，，17： | 9 |

| 20 | Microstructures and tensile properties of Mg-Zn-(Gd)-Zr alloys extruded at various temperatures显示文摘The microstructures and tensile properties of Mg-6.0 Zn-0.6 Zr(ZK60) and ZK60 + 1.8 Gd(ZEK620(RE = Gd)) alloys extruded at 290, 305, 320, 340 and360 ℃ were investigated. The results indicate that Gd addition can refine the microstructures of ZK60 alloy and the extrusion parameters such as the extrusion temperature will influence the tensile properties of both as-extruded ZK60 and ZEK620 alloys, although it is much slighter for ZK60 alloy. And the sensitivity is closely related to the textures developed during extrusion. In addition, Gd addition will also clearly improve the tensile strength at room temperature(24 ℃) and particularly at high temperatures(150 and 200 ℃), due to the much finer grains and smaller intermetallic particles. The highest strength is achieved in the as-extruded ZEK620 alloy with extrusion temperature of 320 ℃, with ultimate tensile strength(UTS) and tensile yield strength(TYS) of 405 and375 MPa, respectively, which are improved by approximately 9% and 11% than those of the as-extruded ZK60 alloy which owns the highest strength at extrusion temperature of 290 ℃. | Xin Qiu Qiang Yang Kai Guan Fanqiang Bu Zhan-Yi Cao Yong-Bing Liu Jian Meng | 2017 | Rare Metals2017，36，12： | 9 |
