| 1 | Annual report on status of cancer in China,2010显示文摘Objective:Population-based cancer registration data in 2010 were collected,evaluated and analyzed by the National Central Cancer Registry(NCCR) of China.Cancer incident new cases and cancer deaths were estimated.Methods:There were 219 cancer registries submitted cancer incidence and death data in 2010.All data were checked and evaluated on basis of the criteria of data quality from NCCR.Total 145 registries' data were qualified and accepted for cancer statistics in 2010.Pooled data were stratified by urban/rural,area,sex,age group and cancer site.Cancer incident cases and deaths were estimated using age-specific rates and national population.The top ten common cancers in different groups,proportion and cumulative rate were also calculated.Chinese census in 2000 and Segi's population were used for age-standardized incidence/ mortality rates.Results:All 145 cancer registries(63 in urban and 82 in rural) covered a total of 158,403,248 population(92,433,739 in urban and 65,969,509 in rural areas).The estimates of new cancer incident cases and cancer deaths were 3,093,039 and 1,956,622 in 2010,respectively.The morphology verified cases(MV%) accounted for 67.11% and 2.99% of incident cases were identified through death certifications only(DCO%) with mortality to incidence ratio(M/I) of 0.61.The crude incidence rate was 235.23/100,000(268.65/100,000 in males,200.21/100,000 in females),age-standardized incidence rates by Chinese standard population(ASIRC,2000) and by world standard population(ASIRW) were 184.58/100,000 and 181.49/100,000 with the cumulative incidence rate(0-74 years old) of 21.11%.The cancer incidence and ASIRC were 256.41/100,000 and 187.53/100,000 in urban areas whereas in rural areas,they were 213.71/100,000 and 181.10/100,000,respectively.The crude cancer mortality in China was 148.81/100,000(186.37/100,000 in males and 109.42/100,000 in females),age-standardized incidence rates by Chinese standard population(ASMRC,2000) and by world standard population(ASMRW) were 113.92/100,000 and 112.86/100,000,and the cumulative incidence rate(0-74 years old) was 12.78%.The cancer mortality and ASMRC were 156.14/100,000 and 109.21/100,000 in urban areas,whereas in rural areas,they were 141.35/100,000 and 119.00/100,000 respectively.Lung cancer,gastric cancer,colorectal cancer,liver cancer,esophageal cancer,pancreas cancer,encephaloma,lymphoma,female breast cancer and cervical cancer,were the most common cancers,accounting for 75% of all cancer cases in urban and rural areas.Lung cancer,gastric cancer,liver cancer,esophageal cancer,colorectal cancer,pancreatic cancer,breast cancer,encephaloma,leukemia and lymphoma accounted for 80% of all cancer deaths.Conclusions:The coverage of cancer registration population had a rapid increase and could reflect cancer burden in each area and population.As the basis of cancer control program,cancer registry plays an irreplaceable role in cancer epidemic surveillance,evaluation of cancer control programs and making anticancer strategy.China is facing serious cancer burden and prevention and control should be enhanced. | Wanqing Chen Rongshou Zheng Siwei Zhang Ping Zhao Hongmei Zeng Xiaonong Zou Jie He | 2014 | Chinese Journal of Cancer Research2014,26,1: | 198 |
| 2 | Cancer incidence and mortality in China, 2014显示文摘Background: National Central Cancer Registry of China(NCCRC) updated nationwide cancer statistics using population-based cancer registry data in 2014 collected from all available cancer registries.Methods: In 2017, 449 cancer registries submitted cancer registry data in 2014, among which 339 registries' data met the criteria of quality control and were included in analysis. These cancer registries covered 288,243,347 population, accounting for about 21.07% of the national population in 2014. Numbers of nationwide new cancer cases and deaths were estimated using calculated incidence and mortality rates and corresponding national population stratified by area, sex, age group and cancer type. The world Segi's population was applied for agestandardized rates.Results: A total of 3,804,000 new cancer cases were diagnosed, the crude incidence rate was 278.07/100,000(301.67/100,000 in males, 253.29/100,000 in females) and the age-standardized incidence rate by world standard population(ASIRW) was 186.53/100,000. Calculated age-standardized incidence rate was higher in urban areas than in rural areas(191.6/100,000 vs. 179.2/100,000). South China had the highest cancer incidence rate while Southwest China had the lowest incidence rate. Cancer incidence rate was higher in female for population between20 to 54 years but was higher in male for population younger than 20 years or over 54 years. A total of 2,296,000 cancer deaths were reported, the crude mortality rate was 167.89/100,000(207.24/100,000 in males,126.54/100,000 in females) and the age-standardized mortality rate by world standard population(ASMRW) was106.09/100,000. Calculated age-standardized mortality rate was higher in rural areas than in urban areas(110.3/100,000 vs. 102.5/100,000). East China had the highest cancer mortality rate while North China had the lowest mortality rate. The mortality rate in male was higher than that in female. Common cancer types and major causes of cancer death differed between age group and sex.Conclusions: Heavy cancer burden and its disparities between area, sex and age group pose a major challenge to public health in China. Nationwide cancer registry plays a crucial role in cancer prevention and control. | Wanqing Chen Kexin Sun Rongshou Zheng Hongmei Zeng Siwei Zhang Changfa Xia Zhixun Yang He Li Xiaonong Zou Jie He | 2018 | Chinese Journal of Cancer Research2018,30,1: | 832 |
| 3 | Prevalence of Autism Spectrum Disorder in China:A Nationwide Multi-center Population-based Study Among Children Aged 6 to 12 Years显示文摘This study aimed to obtain the first national estimate of the prevalence of autism spectrum disorder(ASD) in Chinese children.We targeted the population of 6 to 12-year-old children for this prevalence study by multistage convenient cluster sampling.The Modified Chinese Autism Spectrum Rating Scale was used for the screening process.Of the target population of 142,086 children,88.5%(n=125,806) participated in the study.A total of 363 children were confirmed as having ASD.The observed ASD prevalence rate was 0.29%(95% CI:0.26%-0.32%) for the overall population.After adjustment for response rates,the estimated number of ASD cases was867 in the target population sample,thereby achieving an estimated prevalence of 0.70%(95% CI:0.64%-0.74%).The prevalence was significantly higher in boys than in girls(0.95%;95% CI:0.87%-1.02% versus 0.30%;95%CI:0.26%-0.34%;P <0.001).Of the 363 confirmed ASD cases,43.3% were newly diagnosed,and most of those(90.4%) were attending regular schools,and 68.8% of the children with ASD had at least one neuropsychiatric comorbidity.Our findings provide reliable data on the estimated ASD prevalence and comorbidities in Chinese children. | Hao Zhou Xiu Xu Weili Yan Xiaobing Zou Lijie Wu Xuerong Luo Tingyu Li Yi Huang Hongyan Guan Xiang Chen Meng Mao Kun Xia Lan Zhang Erzhen Li Xiaoling Ge Lili Zhang Chunpei Li Xudong Zhang Yuanfeng Zhou Ding Ding Andy Shih Eric Fombonne Yi Zheng Jisheng Han Zhongsheng Sun Yong-hui Jiang Yi Wang LATENT-NHC Study Team | 2020 | Neuroscience Bulletin2020,36,9: | 158 |
| 4 | The incidences and mortalities of major cancers in China, 2010显示文摘To estimate the cancer incidences and mortalities in China in 2010, the National Central Cancer Registry(NCCR) of China evaluated data for the year of 2010 from 145 qualified cancer registries covering 158,403,248 people(92,433,739 in urban areas and 65,969,509 in rural areas). The estimates of new cancer cases and cancer deaths were 3,093,039 and 1,956,622 in 2010, respectively. The percentage of morphologically verified cases were 67.11%; 2.99% of incident cases were identified through death certification only, with the mortality to incidence ratio of 0.61. The crude incidence was 235.23/100,000(268.65/100,000 in males and 200.21/100,000 in females). The age-standardized rates by Chinese standard population(ASR China) and by world standard population(ASR world) were 184.58/100,000 and 181.49/100,000, respectively, with a cumulative incidence(0-74 years old) of 21.11%. The crude cancer mortality was 148.81/100,000(186.37/100,000 in males and 109.42/100,000 in females). The ASR China and ASR world were 113.92/100,000 and 112.86/100,000, respectively, with a cumulative mortality of 12.78%. Lung, breast, gastric, liver, esophageal, colorectal, and cervical cancers were the most common cancers. Lung, liver, gastric, esophageal, colorectal, breast, and pancreatic cancers were the leading causes of cancer deaths. The coverage of cancer registration has rapidly increased in China in recent years and may reflect more accurate cancer burdens among populations living in different areas. Given the increasing cancer burden in the past decades, China should strengthen its cancer prevention and control. | Wan-Qing Chen Rong-Shou Zheng Si-Wei Zhang Hong-Mei Zeng Xiao-Nong Zou | 2014 | Chinese Journal of Cancer2014,33,8: | 62 |
| 5 | Gallstone recurrence after successful percutaneous cholecystolithotomy:a 10-year follow-up of 439 cases显示文摘BACKGROUND: Stone recurrence is a major problem in the medication of gallstones with gallbladder preservation. The aim of this study was to determine the long-term recurrence rate of gallstones and the clinical outcome after successful percutaneous cholecystolithotomy (PCCL) treatment, and to investigate the possible risk factors for gallstone recurrence. METHODS: After successful PCCL for gallstones, 439 patients were followed up during a 10-year period. The long-term gallstone recurrence rate and clinical outcome were evaluated. Risk factors associated with stone recurrence were identified. RESULTS: Gallstone recurrence was detected in 182 of 439 PCCL patients, giving an overall recurrence rate of 41.46%. The cumulative gallstone recurrence rate for each of the 10 post-operative years was 9.57%, 18.91%, 27.33%, 34.14%, 37.59%, 39.86%, 41.90%, 42.73%, 42.85%, and 43.21%, respectively. Among these recurrent patients, 94 were asymptomatic, 80 suffered from nonspecific upper gastrointestinal symptoms and 8 suffered from abdominal pain or biliary colic. Thirty-eight of the 182 patients were retreated with cholecystectomy. The risk factors for stone recurrence included a family history of gallstones, preference for fatty food, accompanying liver disease, multiple stones and poor gallbladder function pre-PCCL. CONCLUSIONS: In this study, the overall recurrence rate of gallstone was 41.46% during a 10-year period. The highest frequency of gallstone recurrence was during the 5th to 6th postoperative years and then continued to slowly increase. Risk factors for stone recurrence varied.We suggest that the use of PCCL in patients with gallstones should be considered carefully because of stone recurrence. | Zou, Yi-Ping Du, Ji-Dong Li, Wei-Min Xiao, Yin-Qi Xu, Hong-Bin Zheng, Fang Huang, Hui Liu, Hao-Run Li, Hu-Cheng | 2007 | Hepatobiliary & Pancreatic Diseases International2007,6,2: | 43 |
| 6 | Nasopharyngeal carcinoma incidence and mortality in China in 2009显示文摘Nasopharyngeal carcinoma (NPC) is rare globally but common in China and exhibits a distinct ethnic and geographic distribution. In 2009, the National Central Cancer Registry in China provided real-time surveillance information on NPC. Individual NPC cases were retrieved from the national database based on the ICD-10 topography code C11. The crude incidence and mortality of NPC were calculated by sex and location (urban/rural). China's population in 1982 and Segi's world population structures were used to determine age-standardized rates. In regions covered by the cancer registries in 2009, the crude incidence of NPC was 3.61/100,000 (5.08/100,000 in males and 2.10/100,000 in females; 4.19/100,000 in urban areas and 2.42/100,000 in rural areas). Age-standardized incidences by Chinese population (ASIC) and Segi's world population (ASIW) were 2.05/100,000 and 2.54/100,000, respectively. The crude mortality of NPC was 1.99/100,000 (2.82/100,000 in males and 1.14/100,000 in females; 2.30/100,000 in urban areas and 1.37/100,000 in rural areas). The age-standardized mortalities by Chinese population (ASMC) and world population (ASMW) were 1.04/100,000 and 1.35/100,000, respectively. The incidence and mortality of NPC were higher in males than in females and higher in urban areas than in rural areas. Both agespecific incidence and mortality were relatively low in persons younger than 30 years old, but these rates dramatically increased. Incidence peaked in the 60-64 age group and mortality peaked in the over 85 age group. Primary and secondary prevention, such as lifestyle changes and early detection, should be carried out in males and females older than 30 years of age. | Zhi-Jian Xu Rong-Shou Zheng Si-Wei Zhang Xiao-Nong Zou Wan-Qing Chen | 2013 | Chinese Journal of Cancer2013,32,8: | 34 |
| 7 | Carbon Dioxide, Methane, and Nitrous Oxide Emissions from a Rice-Wheat Rotation as Affected by Crop Residue Incorporation and Temperature显示文摘Field measurements were made from June 2001 to May 2002 to evaluate the e?ect of crop residue application and temperature on CO2, CH4, and N2O emissions within an entire rice-wheat rotation season. Rapeseed cake and wheat straw were incorporated into the soil at a rate of 2.25 t hm?2 when the rice crop was transplanted in June 2001. Compared with the control, the incorporation of rapeseed cake enhanced the emissions of CO2, CH4, and N2O in the rice-growing season by 12.3%, 252.3%, and 17.5%, respectively, while no further e?ect was held on the emissions of CO2 and N2O in the following wheat- growing season. The incorporation of wheat straw enhanced the emissions of CO2 and CH4 by 7.1% and 249.6%, respectively, but reduced the N2O emission by 18.8% in the rice-growing season. Signi?cant reductions of 17.8% for the CO2 and of 12.9% for the N2O emission were observed in the following wheat- growing season. A positive correlation existed between the emissions of N2O and CO2 (R2 = 0.445,n = 73,p < 0.001) from the rice-growing season when N2O was emitted. A trade-o? relationship between the emissions of CH4 and N2O was found in the rice-growing season. The CH4 emission was signi?cantly correlated with the CO2 emission for the period from rice transplantation to ?eld drainage, but not for the entire rice-growing season. In addition, air temperature was found to regulate the CO2 emissions from the non-waterlogged period over the entire rice-wheat rotation season and the N2O emissions from the non- waterlogged period of the rice-growing season, which can be quantitatively described by an exponential function. The temperature coe?cient (Q10) was then evaluated to be 2.3±0.2 for the CO2 emission and 3.9±0.4 for the N2O emission, respectively. | ZOU Jianwen(邹建文) HUANG Yao(黄耀) ZONG Lianggang(宗良纲) ZHENG Xunhua(郑循华) WANG Yuesi(王跃思) | 2004 | Advances in Atmospheric Sciences2004,21,5: | 29 |

| 9 | Changes of Antioxidative Enzymes and Lipid Peroxidation in Leaves and Roots of Waterlogging-Tolerant and Waterlogging-Sensitive Maize Genotypes at Seedling Stage显示文摘To better understand the physiological and biochemical mechanisms of waterlogging tolerance, waterlogging effects on lipid peroxidation and the activity of antioxidative enzymes were investigated in leaves and roots of two maize genotypes, HZ32 (waterlogging-tolerant) and K12 (waterlogging-sensitive). Potted maize plants were waterlogged at the second leaf stage under glasshouse conditions. Leaves and roots were harvested 1 d before and 2, 4, 6, 8 and 10 d after the start of waterlogging treatment. Through comparing the activities of superoxide dismutase (SOD), ascorbate peroxidase (APX), glutathione reductase (GR), catalase (CAT) and guaiacol peroxidase (POD) between waterlogging-tolerant and waterloggingsensitive genotype, we deduced that CAT was the most important H2O2 scavenging enzyme in leaves, while APX seemed to play a key role in roots. POD, APX, GR and CAT activities in conjunction with SOD seem to play an essential protective role in the O2-. and H2O2 scavenging process. Lipid peroxidation was enhanced significantly only in K12 (P < 0.001) and there was no difference (P > 0.05) in HZ32 up to 6 d after waterlogging stress. These results indicated that oxidative stress may play an important role in waterlogging-stressed maize plants and that the greater protection of HZ32 leaves and roots from waterlogging-induced oxidative damage results, at least in part, through the maintenance of increased antioxidant enzyme activity. | TANG Bin XU Shang-zhong ZOU Xi-ling ZHENG Yong-lian QIU Fa-zhan | 2010 | Agricultural Sciences in China2010,9,5: | 26 |
| 10 | Preliminary Scientific Results of Chang'E-1 Lunar Orbiter:Based on Payloads Detection Data in the First Phase显示文摘Chang'E-1 lunar Orbiter was launched by Long March 3A rocket from Xichang Satel-lite Launch Center at 18:05BT(Beijing Time) Oct.24,2007.It is the first step of its ambitious three-stage moon program,a new milestone in the Chinese space exploration history.The primary science objectives of Chang'E-1 lunar orbiter are to obtain three-Dimension(3D) stereo images of the lunar surface,to analyze the distribution and abundance of elements on the surface,to investigate the thickness of lunar soil,evaluate helium-3 resources and other characteristics,and to detect the space environment around the moon.To achieve the above four mission objectives,eight sets of scientific instruments are chosen as the payloads of the lunar orbiter,including a CCD stereo camera(CCD),a Sagnac-based interferometer spectrometer(ⅡM),a Laser Altimeter(LAM),a Microwave Radiometer(MRM),a Gamma-Ray Spectrometer(GRS),an X-ray spectrometer(XRS),a High-Energy Particle Detector(HPD),and two Solar Wind Ion Detectors(SWID).The detected data of the payloads show that all payloads work well.This paper introduces the status of payloads in the first phase and preliminary scientific results. | OUYANG Ziyuan JIANG Jingshan LI Chunlai SUN Huixian ZOU Yongliao LIU Jianzhong LIU Jianjun ZHAO Baochang REN Xin YANG Jianfeng ZHANG Wenxi WANG Jianyu MOU Lingli CHANG Jin ZHANG Liyan WANG Huanyu LI Yongquan ZHANG Xiaohui ZHENG Yongchun WANG Shijin BIAN Wei | 2008 | 空间科学学报2008,28,5: | 24 |
| 11 | The global image of the Moon obtained by the Chang'E-1:Data processing and lunar cartography显示文摘The global lunar image of the first phase of Chinese Lunar Exploration Program is the first image that covered all over the surface of the Moon. It will serve as a critical foundation for succeeding exploration and scientific research. In this paper, the acquisition, characteristics, and data quality of Chang'E-1 CCD image data are described in detail. Also described are the methodology and procedure of data processing. According to rule of planetary cartography, the image data have been processed, geometrically corrected, and then mosaicked and merged in a scale of 1:2.5 million. The results of data processing and charting show that the image data of Chang'E-1 CCD and their geometric precision meet the demand of charting a map in the scale of 1:2.5 million. The relative geometric positioning precision of the global image is better than 240 m, and the absolute geometric positioning precision is slightly better than that of the ULCN2005 and Clementine lunar basemap (V2.0). The plane positioning precision is approximately 100-1500 m. This global image proves to be the best global image of the Moon so far in terms of space coverage, image quality, and positioning precision. | LI ChunLai1, LIU JianJun1, REN Xin1, MOU LingLi1, ZOU YongLiao1, ZHANG HongBo1, Lü Chang1, LIU JianZhong1, ZUO Wei1, SU Yan1, WEN WeiBin1, BIAN Wei1, ZHAO BaoChang2, YANG JianFeng2, ZOU XiaoDuan1, WANG Min1, XU Chun1, KONG DeQing1, WANG XiaoQian1, WANG Fang1, GENG Liang1, ZHANG ZhouBin1, ZHENG Lei1, ZHU XinYing1, LI JunDuo1 & OUYANG ZiYuan11 National Astronomical Observatories, Chinese Academy of Sciences, Beijing 100012, China 2 Xi’an Institute of Optics and Precision Mechanics, Chinese Academy of Sciences, Xi’an 710119, China | 2010 | Science China Earth Sciences2010,53,8: | 22 |
| 12 | Intraoperative radiofrequency ablation combined with ^(125)iodine seed implantation for unresectable pancreatic cancer显示文摘AIM: To evaluate the feasibility, efficacy and safety of intraoperative radiofrequency ablation (RFA) combined with 125 iodine seed implantation for unresectable pancreatic cancer. METHODS: Thirty-two patients (21 males and 11 females) at the age of 68 years (range 48-90 years) with unresectable locally advanced pancreatic cancer admitted to our hospital from January 2006 to May 2008 were enrolled in this study. The tumor, 4-12 cm in diameter, located in pancreatic head of 23 patients and in pancreatic body and tail of 9 patients, was found to be unresectable during operation. Diagnosis of pancreatic cancer was made through intraoperative biopsy. Patients were treated with FRA combined with 125 iodine seed implantation. In brief, a RFA needle was placed, which was confirmed by intraoperative ultrasound to decrease the potential injury of surrounding vital structures, a 125 iodine seed was implanted near the blood vessels and around the tumor border followed by bypass palliative procedure (cholangio-jejunostomy and/or gastrojejunostomy) in 29 patients.RESULTS: The serum CA 19-9 level was decreased from 512 ± 86 U/mL before operation to 176 ± 64 U/mL, 108 ± 42 U/mL and 114 ± 48 U/mL, respectively, 1, 3 and 6 mo after operation (P < 0.05). The pain score on day 7 after operation, 1 and 3 mo after combined therapy was decreased from 5.86 ± 1.92 before operation to 2.65 ± 1.04, 1.65 ± 0.88 and 2.03 ± 1.16, respectively, after operation (P < 0.05). The rate of complete response (CR), partial response (PR), stable disease (SD), progressive disease (PD) in 32 patients was 21.8% (7/32), 56.3% (18/32), 15.6% (5/32) and 6.3% (2/32), respectively, 6 mo after operation, with a median overall survival time of 17. 5 mo. The median survival time of patients at stage Ⅲ was longer than that of those at stage Ⅳ (19 mo vs 10 mo, P = 0.0026). The median survival time of patients who received and did not receive chemotherapy after operation was 20 mo and 16 mo, respectively (P = 0.0176). Of the 32 patients, 3 (10.6%) experienced postoperative complications including transient biliary leaks in 2 patients and acute pancreatitis in 1 patient. All the patients recovered well after conservative support treatment. CONCLUSION: Intraoperative RFA combined with 125 iodine seed implantation is a feasible and safe procedure for unresectable pancreatic cancer with acceptable minor complications, and can prolong the survival time of patients, especially those at stage Ⅲ. | Yi-Ping Zou Wei-Min Li Fang Zheng Fu-Cheng Li Hui Huang Ji-Dong Du Hao-Run Liu | 2010 | World Journal of Gastroenterology2010,16,40: | 21 |
| 13 | High-resolution records of Holocene from the Shuangchi Maar Lake in Hainan Island显示文摘The results of sedimentary characteristics, grain-size, clay mineral, C/N and pollen analysis reveal the evolution history of the Shuangchi Maar Lake of Hainan Island as well as the short-term climate variations in tropical areas. It is testified that the Maar sediment system was sensitive in recording the rapid climate changes in the Holocene. These multidisciplinary results demonstrate that the thermal maximum in the Holocene climate lasted from 7200 to 2700 aBP, with several abrupt ephemeral vibrations occurring between 7250-6120 aBP and at around 4460, 3850 and 2700 aBP. In the late Holocene, particularly at ~2700 aBP, a distinct environmental change indicating an important climate transition in the tropical eastern Asia was recorded, probably responding to the enhancement of ENSO phenomena in the Pacific Ocean. In addition, the high-resolution algae record clearly indicates periodical climate fluctuations at 500 a cyclicity during the last 2500 years. | ZHENG Zhuo, WANG Jianghua, WANG Bing, LIU Chunlian, ZOU Heping, ZHANG Hua, DENG Yun & BAI Yan Department of Earth Sciences, Zhongshan University, Guangzhou 510275, China (e-mail: ee29@zsu.edu.cn) | 2003 | Chinese Science Bulletin2003,48,5: | 20 |
| 14 | Laser altimetry data of Chang'E-1 and the global lunar DEM model显示文摘The Laser AltiMeter (LAM), as one of the main payloads of Chang'E-1 probe, is used to measure the topography of the lunar surface. It performed the first measurement at 02:22 on November 28th, 2007. Up to December 4th 2008, the total number of measurements was approximately 9.12 million, covering the whole surface of the Moon. Using the LAM data, we constructed a global lunar Digtal Elevation Model (DEM) with 3 km spatial resolution. The model shows pronounced morphological characteristics, legible and vivid details of the lunar surface. The plane positioning accuracy of the DEM is 445 m (1σ), and the vertical accuracy is 60 m (1σ). From this DEM model, we measured the full range of the altitude difference on the lunar sur-face, which is about 19.807 km. The highest point is 10.629 km high, on a peak between crater Korolev and crater Dirichlet-Jackson at (158.656°W, 5.441°N) and the lowest point is -9.178 km in height, inside crater Antoniadi (172.413°W, 70.368°S) in the South Pole-Aitken Basin. By comparison, the DEM model of Chang'E-1 is better than the USA ULCN2005 in accuracy and resolution and is probably identical to the DEM of Japan SELENE, but the DEM of Chang'E-1 reveals a new lowest point, clearly lower than that of SELENE. | LI ChunLai1, REN Xin1, LIU JianJun1, ZOU XiaoDuan1, MU LingLi1, WANG JianYu2, SHU Rong2, ZOU YongLiao1, ZHANG HongBo1, Lü Chang1, LIU JianZhong1, ZUO Wei1, SU Yan1, WEN WeiBin1, BIAN Wei1, WANG Min1, XU Chun1, KONG DeQing1, WANG XiaoQian1, WANG Fang1, GENG Liang1, ZHANG ZhouBin1, ZHENG Lei1, ZHU XinYing1, LI JunDuo1 & OUYANG ZiYuan1 1 National Astronomical Observatories, Chinese Academy of Sciences, Beijing 100012, China 2 Shanghai Institute of Technical Physics, Chinese Academy of Sciences, Shanghai 200083, China | 2010 | Science China Earth Sciences2010,53,11: | 19 |

| 16 | Comparison of 5-hydroxytryptophan signaling pathway characteristics in diarrhea-predominant irritable bowel syndrome and ulcerative colitis显示文摘AIM: To study differences in the visceral sensitivity of the colonic mucosa between patients with diarrheapredominant irritable bowel syndrome(IBS-D) and those with ulcerative colitis(UC) in remission and to relate these differences with changes in the 5-hydroxytryptophan(5-HT) signaling pathway. METHODS: Gastrointestinal symptoms were used to determine the clinical symptom scores and rectal visceral sensitivity of patients with IBS-D and patients with UC in remission. Blood levels of 5-HT and5-hydroxyindoleacetic acid(5-HIAA) were measured using an HPLC-electrochemical detection system. The levels of 5-HT 3 receptor(3R), 4R, and 7R m RNAs in colonic biopsy samples were detected using reverse transcription-polymerase chain reaction. The protein expression of TPH1 was analyzed by Western blot and immunohistochemistry.RESULTS: Abdominal pain or discomfort, stool frequency, and the scores of these symptoms in combination with gastrointestinal symptoms were higher in the IBS-D and UC groups than in the control groups. However, no significant differences were observed between the IBS-D and UC remission groups. With respect to rectal visceral sensitivity, the UC remission and IBS-D groups showed a decrease in the initial perception threshold, defecating threshold and pain threshold. However, these groups exhibited significantly increased anorectal relaxation pressure. Tests examining the main indicators of the 5-HT signaling pathway showed that the plasma 5-HT levels, 5-HIAA concentrations, TPH1 expression in the colonic mucosa, and 5-HT3 R and 5-HT5 R expression were increased in both the IBS-D and the UC remission groups; no increases were observed with respect to 5-HT7 R expression.CONCLUSION: The IBS-D and UC groups showed similar clinical symptom scores, visceral sensitivity, and levels of serotonin signaling pathway indicators in the plasma and colonic mucosa. However, the pain threshold and 5-HT7 R expression in the colonic mucosa were significantly different between these groups. The results reveal that(1) IBS-D and UC are related to visceral sensitivity pathogenesis and the clinical manifestations of these conditions and(2) the observed differences in visceral hypersensitivity are possibly due to differences in levels of the 5-HT7 receptor, a component of the 5-HT signaling pathway. | Feng-Yan Yu Shao-Gang Huang Hai-Yan Zhang Hua Ye Hong-Gang Chi Ying Zou Ru-Xi Lv Xue-Bao Zheng | 2016 | World Journal of Gastroenterology2016,22,12: | 19 |
| 17 | Synthetic hexaploid wheat and its utilization for wheat genetic improvement in China显示文摘Synthetic hexaploid wheat (Triticum turgidum × Aegilops tauschii) was created to explore for novel genes from T. turgidum and Ae. tauschii that can be used for common wheat improvement. In the present paper, research advances on the utilization of synthetic hexaploid wheat for wheat genetic improvement in China are reviewed. Over 200 synthetic hexaploid wheat (SHW) accessions from the International Maize and Wheat Improvement Centre (CIMMYT) were introduced into China since 1995. Four cultivars derived from these, Chuanmai 38, Chuanmai 42, Chuanmai 43 and Chuanmai 47, have been released in China. Of these, Chuanmai 42, with large kernels and resistance to stripe rust, had the highest average yield (> 6 t/ha) among all cultivars over two years in Sichuan provincial yield trials, outyielding the commercial check cultivar Chuanmai 107 by 22.7%. Meanwhile, by either artificial chromosome doubling via colchicine treatment or spontaneous chromosome doubling via a union of unreduced gametes (2n) from T. turgidum-Ae. tauschii hybrids, new SHW lines were produced in China. Mitotic-like meiosis might be the cytological mechanism of spontaneous chromosome doubling. SHW lines with genes for spontaneous chromosome doubling may be useful for producing new SHW-alien amphidiploids and double haploid in wheat genetic improvement. | Wuyun Yang Dengcai Liu Jun Li Lianquan Zhang Huiting Wei Xiaorong Hu Youliang Zheng Zhouhu He Yuchun Zou | 2009 | Journal of Genetics and Genomics2009,36,9: | 18 |
