1Liver cancer incidence and mortality in China: Temporal trends and projections to 2030显示文摘Objective: Liver cancer is one of the most common cancers and major cause of cancer deaths in China,which accounts for over 50% of new cases and deaths worldwide.The systematic liver cancer statistics including of projection through 2030 could provide valuable information for prevention and control strategies in China,and experience for other countries.Methods: The burden of liver cancer in China in 2014 was estimated using 339 cancer registries' data selected from Chinese National Cancer Center(NCC).Incident cases of 22 cancer registries were applied for temporal trends from 2000 to 2014.The burden of liver cancer through 2030 was projected using age-period-cohort model.Results: About 364,800 new cases of liver cancer(268,900 males and 95,900 females) occurred in China,and about 318,800 liver cancer deaths(233,500 males and 85,300 females) in 2014.Western regions of China had the highest incidence and mortality rates.Incidence and mortality rates decreased by about 2.3% and 2.6% per year during the period of 2000-2014,respectively,and would decrease by more than 44% between 2014 and 2030 in China.The young generation,particularly for those aged under 40 years,showed a faster down trend.Conclusions: Based on the analysis,incidence and mortality rates of liver cancer are expected to decrease through 2030,but the burden of liver cancer is still serious in China,especially in rural and western areas.Most cases of liver cancer in China can be prevented through vaccination and more prevention efforts should be focused on high risk groups.Rongshou Zheng Chunfeng Qu Siwei Zhang Hongmei Zeng Kexin Sun Xiuying Gu Changfa Xia Zhixun Yang He Li Wenqiang Wei Wanqing Chen Jie He 2018Chinese Journal of Cancer Research2018,30,6:132
2Breast cancer incidence and mortality in women in China: temporal trends and projections to 2030显示文摘Objective:Breast cancer was the most common cancer and the fifth cause of cancer deaths among women in China in 2015.The evaluation of the long-term incidence and mortality trends and the prediction of the future burden of breast cancer could provide valuable information for developing prevention and control strategies.Methods:The burden of breast cancer in China in 2015 was estimated by using qualified data from 368 cancer registries from the National Central Cancer Registry.Incident cases and deaths in 22 cancer registries were used to assess the time trends from 2000 to 2015.A Bayesian age-period-cohort model was used to project the burden of breast cancer to 2030.Results:Approximately 303,600 new cases of breast cancer(205,100 from urban areas and 98,500 from rural areas)and 70,400 breast cancer deaths(45,100 from urban areas and 24,500 from rural areas)occurred in China in 2015.Urban regions of China had the highest incidence and mortality rates.The most common histological subtype of breast cancer was invasive ductal carcinoma,followed by invasive lobular carcinoma.The age-standardized incidence and mortality rates increased by 3.3%and 1.0%per year during 2000–2015,and were projected to increase by more than 11%until 2030.Changes in risk and demographic factors between 2015 and 2030 in cases are predicted to increase by approximately 13.3%and 22.9%,whereas deaths are predicted to increase by 13.1%and 40.9%,respectively.Conclusions:The incidence and mortality of breast cancer continue to increase in China.There are no signs that this trend will stop by 2030,particularly in rural areas.Effective breast cancer prevention strategies are therefore urgently needed in China.Shaoyuan Lei Rongshou Zheng Siwei Zhang Ru Chen Shaoming Wang Kexin Sun Hongmei Zeng Wenqiang Wei Jie He 2021Cancer Biology & Medicine2021,18,3:53
3Global patterns of breast cancer incidence and mortality:A population-based cancer registry data analysis from 2000 to 2020显示文摘Background:Breast cancer is the most commonly diagnosed cancer and leading cause of cancer death among women worldwide but has patterns and trends which vary in different countries.This study aimed to evaluate the global patterns of breast cancer incidence and mortality and analyze its temporal trends for breast cancer prevention and control.Methods:Breast cancer incidence and mortality data in 2020 were obtained from the GLOBOCAN online database.Continued data from the Cancer Incidence in Five Continents Time Trends,the International Agency for Research on cancer mortality and China National Central Cancer Registry were used to analyze the time trends from 2000 to 2015 through Joinpoint regression,and annual average percent changes of breast cancer incidence and mortality were calculated.Association between Human Development Index and breast cancer incidence and mortality were estimated by linear regression.Results:There were approximately 2.3 million new breast cancer cases and 685,000 breast cancer deaths worldwide in 2020.Its incidence and mortality varied among countries,with the age-standardized incidence ranging from the highest of 112.3 per 100,000 population in Belgium to the lowest of 35.8 per 100,000 population in Iran,and the age-standardized mortality from the highest of 41.0 per 100,000 population in Fiji to the lowest of 6.4 per 100,000 population in South Korea.The peak age of breast cancer in some Asian and African countries were over 10 years earlier than in European or American countries.As for the trends of breast cancer,the age-standardized incidence rates significantly increased in China and South Korea but decreased in the United States of America(USA)during 2000-2012.Meanwhile,the age-standardized mortality rates significantly increased in China and South Korea but decreased in the United Kingdom,the USA,and Australia during 2000 and 2015.Conclusions:The global burden of breast cancer is rising fast and varies greatly among countries.The incidence and mortality rates of breast cancer increased rapidly in China and South Korea but decreased in the USA.Increased health awareness,effective prevention strategies,and improved access to medical treatment are extremely important to curb the snowballing breast cancer burden,especially in the most affected countries.Shaoyuan Lei Rongshou Zheng Siwei Zhang Shaoming Wang Ru Chen Kexin Sun Hongmei Zeng Jiachen Zhou Wenqiang Wei 2021Cancer Communications2021,41,11:55
4Annual cost of illness of stomach and esophageal cancer patientsin urban and rural areas in China: A multi-center study显示文摘Objective: Stomach and esophageal cancer are imposing huge threats to the health of Chinese people whereas there were few studies on the financial burden of the two cancers.Methods: Costs per hospitalization of all patients with stomach or esophageal cancer discharged between September 2015 and August 2016 in seven cities/counties in China were collected, together with their demographic information and clinical details. Former patients in the same hospitals were sampled to collect information on annual direct non-medical cost, indirect costs and annual number of hospitalization. Annual direct medical cost was obtained by multiplying cost per hospitalization by annual number of hospitalization. Annual cost of illness(ACI)was obtained by adding the average value of annual direct medical cost, direct non-medical cost and indirect cost,stratified by sex, age, clinical stage, therapy and pathologic type in urban and rural areas. Costs per hospitalization were itemized into eight parts to calculate the proportion of each part. All costs were converted to 2016 US dollars(1 USD=6.6423 RMB).Results: Totally 19,986 cases were included, predominately male. Mean ages of stomach cancer and urban patients were lower than that of esophageal cancer and rural patients. ACI of stomach and esophageal cancer patients were $10,449 and $13,029 in urban areas, and $2,927 and $3,504 in rural areas, respectively. Greater ACI was associated with male, non-elderly patients as well as those who were in stage I and underwent surgeries.Western medicine fee took the largest proportion of cost per hospitalization.Conclusions: The ACI of stomach and esophageal cancer was tremendous and varied substantially among the population in China. Preferential policies of medical insurance should be designed to tackle with this burden and further reduce the health care inequalities.Zhixun Yang Hongmei Zeng Ruyi Xia Qian Liu Kexin Sun Rongshou Zheng Siwei Zhang Changfa Xia He Li Shuzheng Liu Zhiyi Zhang Yuqin Liu Guizhou Guo Guohui Song Yigong Zhu Xianghong Wu Bingbing Song Xianzhen Liao Yanfang Chen Wenqiang Wei Guihua Zhuang Wanqing Chen 2018Chinese Journal of Cancer Research2018,30,4:22
5Colorectal cancer burden and trends:Comparison between China and major burden countries in the world显示文摘Objective:To summarize the colorectal cancer(CRC)burden and trend in the world,and compare the difference of CRC burden between other countries and China.Methods:Incidence and mortality data were extracted from the GLOBOCAN2018 and Cancer Incidence in Five Continents.Age-specific incidence trend was conducted by Joinpoint analysis and average annual percent changes were calculated.Results:About 1.85 million new cases and 0.88 million deaths were expected in 2018 worldwide,including 0.52 million(28.20%)new cases and 0.25 million(28.11%)deaths in China.Hungary had the highest age-standardized incidence and mortality rates in the world,while for China,the incidence and mortality rates were only half of that.CRC incidence and mortality were highly correlated with human development index(HDI).Unlike the rapid increase in Republic of Korea and the downward trend in Canada and Australia,the age-standardized incidence rates by world standard population in China and Norway were rising gradually.The age-specific incidence rate in the age group of 50-59 years in China was increasing rapidly,while in Republic of Korea and Canada,the fastest growing age group was 30-39 years.Conclusions:The variations of CRC burden reflect the difference of risk factors,as well as levels of HDI and screening(early detection activities).The burden of CRC in China is high,and the incidence of CRC continues to increase,which may lead to a sustained increase in the burden of CRC in China in the future.Screening should be expanded to control CRC,and focused on young people in China.Jiachen Zhou Rongshou Zheng Siwei Zhang Hongmei Zeng Shaoming Wang Ru Chen Kexin Sun Minjuan Li Jianhua Gu Guihua Zhuang Wenqiang Wei 2021Chinese Journal of Cancer Research2021,33,1:16
6DNA image cytometry test for primary screening of esophageal cancer: a population-based multi-center study in high-risk areas in China显示文摘Objective: To evaluate the feasibility of DNA image cytometry(DNA-ICM) as a primary screening method for esophageal squamous cell cancer(ESCC).Methods: A total of 5,382 local residents aged 40–69 years from three high-risk areas in China(Linzhou in Henan province, Feicheng in Shandong province and Cixian in Hebei province) from 2008 to 2011 were recruited in this population-based screening study. And 2,526 subjects declined to receive endoscopic biopsy examination with Lugol's iodine staining, while 9 and 815 subjects were excluded from liquid-based cytology and DNA-ICM test respectively due to slide quality. Finally, 2,856, 5,373 and 4,567 subjects were enrolled in the analysis for endoscopic biopsy examination, liquid-based cytology and DNA-ICM test, respectively. Sensitivity(SE), specificity(SP), negative predictive values(NPV) and positive predictive values(PPV) as well as their 95% confidence intervals(95% CI) for DNA-ICM, liquid-based cytology and the combination of the two methods were calculated. Receiver operating characteristic(ROC) curves were applied to determine the cutoff point of DNA-ICM for esophageal cancer.Results: DNA-ICM results were significantly correlative with esophageal cancer and precancer lesions(χ~2=18.016, P<0.001). The cutoff points were 5,802, 5,803 and 8,002 based on dissimilar pathological types of low grade intraepithelial neoplasia(LGIN), high grade intraepithelial neoplasia(HGIN), and ESCC, respectively, and 5,803 was chosen in this study considering the SE and SP. The SE, SP, PPV, NPV of DNA-ICM test(cutoff point 5,803) combined with liquid-based cytology [threshold atypical squamous cells of undetermined significance(ASCUS)] were separately 72.1%(95% CI: 70.3%-73.9%), 43.3%(95% CI: 41.3%-45.3%), 22.8%(95% CI: 21.1%-24.5%) and 87.0%(95% CI: 85.7%-88.3%) for LGIN, 85.7%(95% CI: 84.3%-87.1%), 41.3%(95% CI: 39.3%-43.3%), 4.6%(95% CI: 3.8%-5.4%) and 98.9%(95% CI: 98.5%-99.3%) for HGIN, and 96.0%(95% CI: 95.2%-96.8%), 40.8%(95% CI: 38.8%-42.8%), 1.7%(95% CI: 1.2%-2.2%) and 99.9%(95% CI: 99.8%-100.0%) for ESCC.Conclusions: It is possible to use DNA-ICM test as a primary screening method before endoscopic screening for esophageal cancer.Meng Wang Changqing Hao Qing Ma Guohui Song Shanrui Ma Deli Zhao Lin Zhao Xinqing Li Wenqiang Wei 2016Chinese Journal of Cancer Research2016,28,4:15
7Cancer statistics in Chinese older people,2022:current burden,time trends,and comparisons with the US,Japan,and the Republic of Korea显示文摘Largely due to population ageing,the cancer burden from older people has been rising,which imposed considerable pressure on current Chinese healthcare system.We provide comprehensive information about cancer burden of Chinese older people based on the most recent data from National Central Cancer Registry of China.The logarithmic linear regression was used to project the current cancer burden in 2022,and Joinpoint regression was used for temporal trend analysis from 2000 to 2017.We also estimated cancer statistics of older people in the US,Japan and the Republic of Korea for comparisons.It is estimated that 2.79 million cases and 1.94 million deaths occur for Chinese older people,representing 55.8%and 68.2%of cases and deaths in all population in 2022.The overall cancer incidence rate gradually increased among older women,while the mortality rates declined for both sexes.Notably,approximately 10.0%of all cases and 17.7%of all deaths are from people aged over 80 years,and cancer incidence and mortality in this age group showed upward trends for women.Lung cancer and digestive cancers are the leading cancer types for Chinese older people.Compared with other countries,China has lower incidence rates but higher mortality rates for older people.The rapidly growing burden of prostate cancer,breast cancer,colorectal cancer,and declines in esophageal cancer,stomach cancer,and liver cancer among older people indicate the cancer pattern in China is being in a transition stage to that in developed countries.Our findings imply that it should be the national health priority to meet the growing demands for cancer diagnosis,treatment and care services from the older people as the rapid population ageing in next few decades.Wen Ju Rongshou Zheng Siwei Zhang Hongmei Zeng Kexin Sun Shaoming Wang Ru Chen Li Li Wenqiang Wei Jie He 2023Science China(Life Sciences)2023,66,5:15
8ZmCOL3, a CCT gene represses flowering in maize by interfering with the circadian clock and activating expression of ZmCCT显示文摘Flowering time is a trait vital to the adaptation of flowering plants to different environments.Here, we report that CCT domain genes play an important role in flowering in maize(Zea mays L.).Among the 53 CCT family genes we identified in maize, 28 were located in flowering time quantitative trait locus regions and 15 were significantly associated with flowering time, based on candidate-gene association mapping analysis.Furthermore, a CCT gene named ZmCOL3 was shown to be a repressor of flowering.Overexpressing ZmCOL3 delayed flowering time by approximately 4 d, in either long-day or short-day conditions.The absence of one cytosine in the ZmCOL3 3'UTR and the presence of a 551 bp fragment in the promoter region are likely the causal polymorphisms contributing to the maize adaptation from tropical to temperate regions.We propose a modified model of the maize photoperiod pathway, wherein ZmCOL3 acts as an inhibitor of flowering either by transactivating transcription of ZmCCT, one of the key genes regulating maize flowering, or by interfering with the circadian clock.Minliang Jin Xiangguo Liu Wei Jia Haijun Liu Wenqiang Li Yong Peng Yanfang Du Yuebin Wang Yuejia Yin Xuehai Zhang Qing Liu Min Deng Nan Li Xiyan Cui Dongyun Hao Jianbing Yan 2018Journal of Integrative Plant Biology2018,60,6:14
9GBSS-BINDING PROTEIN,encoding a CBM48 domain-containing protein,affects rice quality and yield^∞显示文摘The percentage of amylose in the endosperm of rice(Oryza sativa)largely determines grain cooking and eating qualities.Granule-bound starch synthase I(GBSSI)and GBSSII are responsible for amylose biosynthesis in the endosperm and leaf,respectively.Here,we identified OsGBP,a rice GBSS-binding protein that interacted with GBSSI and GBSSII in vitro and in vivo.The total starch and amylose contents in osgbp mutants were significantly lower than those of wild type in leaves and grains,resulting in reduced grain weight and quality.The carbohydrate-binding module 48(CBM48)domain present in the C-terminus of OsGBP is crucial for OsGBP binding to starch.In the osgbp mutant,the extent of GBSSI and GBSSII binding to starch in the leaf and endospermwas significantly lower than wild type.Our data suggest that OsGBP plays an important role in leaf and endosperm starch biosynthesis by mediating the binding of GBSS proteins to developing starch granules.This elucidation of the function of OsGBP enhances our understanding of the molecular basis of starch biosyn-thesis in rice and contributes information that can be potentially used for the genetic improvement of yield and grain quality.Wei Wang Xiangjin Wei Guiai Jiao Wenqiang Chen Yawen Wu Zhonghua Sheng Shikai Hu Lihong Xie Jiayu Wang Shaoqing Tang Peisong Hu 2020Journal of Integrative Plant Biology2020,62,7:12
10Evaluating efficacy of screening for upper gastrointestinal cancer in China:a study protocol for a randomized controlled trial显示文摘Objective: To evaluate the efficacy and feasibility of screening procedure for upper gastrointestinal cancer in both high-risk and non-high-risk areas in China.Setting: Seven cities/counties, representing three economical-geographical regions(Eastern, Central and Western) in China, were selected as screening centers: three in high-risk areas and four in non-high-risk areas.Participants: Villages/communities in these seven centers regarded as clusters were randomly assigned to either intervention group(screening by endoscopic examination) or control group(with normal community care) in a 1:1ratio stratified by each center. Eligible participants are local residents aged 40–69 years in the selected villages/communities with no history of cancer or endoscopic examination in the latest 3 years who are mentally and physically competent. Those who are not willing to take endoscopic examination or are unwilling to sign the consent form are excluded from the study. Totally 140,000 participants will be enrolled.Interventions: In high-risk areas of upper gastrointestinal cancer, all subjects in screening group will be screened by endoscopy. In non-high-risk areas, 30% of the subjects in screening group, identified through a survey,will be screened by endoscopy.Primary and secondary outcome measures: The primary outcome is the mortality caused by upper gastrointestinal cancer. The secondary outcomes include detection rate, incidence rate, survival rate, and clinical stage distribution. Additional data on quality of life and cost-effectiveness will also be collected to answer important questions regarding screening effects.Conclusions: Screening strategy evaluated in those areas with positive findings may be promoted nationally and applied to the majority of Chinese people. On the other hand, negative findings will provide scientific evidence for abandoning a test and shifting resources elsewhere.Trial registration: The study has been registered with the Protocol Registration System in Chinese Clinical Trial Registry.wanqing chen hongmei zeng ru chen ruyi xia zhixun yang changfa xia rongshou zheng wenqiang wei guihua zhuang xueqin yu jie he 2017Chinese Journal of Cancer Research2017,29,4:11
11Autonomous navigation for a wolfberry picking robot using visual cues and fuzzy control显示文摘Lycium barbarum commonly known as wolfberry or Goji is considered an important ingredient in Japanese,Korean,Vietnamese,and Chinese food and medicine.It is cultivated extensively in these countries and is usually harvested manually,which is laborintensive and tedious task.To improve the efficiency of harvesting and reduce manual labor,automatic harvesting technology has been investigated by many researchers in recent years.In this paper,an autonomous navigation algorithm using visual cues and fuzzy control is proposed for Wolfberry orchards.At first,we propose a new weightage(2.4B-0.9G-R)to convert a color image into a grayscale image for better identification of the trunk of Lycium barbarum,the minimum positive circumscribed rectangle is used to describe the contours.Then,using the contour points the least square method is used to fit the navigation line and a region of interest(ROI)is computed that improves the realtime accuracy of the system.Finally,a set of fuzzy controllers,for pneumatic steering system,is designed to achieve real-time autonomous navigation in wolfberry orchard.Static image experiments show that the average accuracy rate of the algorithm is above 90%,and the average time consumption is approximately 162 ms,with good robustness and real-time performance.The experimental results show that when the speed is 1 km/h,the maximum lateral deviation is less than 6.2 cm and the average lateral deviation is 2.9 cm,which meets the requirements of automatic picking of wolfberry picking robot in real-world environments.Yue Ma Wenqiang Zhang Waqar S.Qureshi Chao Gao Chunlong Zhang Wei Li 2021Information Processing in Agriculture2021,8,1:7
12The involvement of wheat U-box E3 ubiquitin ligase TaPUB1 in salt stress tolerance显示文摘U-box E3 ubiquitin ligases play important roles in the ubiquitin/26 S proteasome machinery and in abiotic stress responses. Ta PUB1-overexpressing wheat(Triticum aestivum L.) were generated to evaluate its function in salt tolerance. These plants had more salt stress tolerance during seedling and flowering stages, whereas the Ta PUB1-RNA interference(RNAi)-mediated knock-down transgenic wheat showed more salt stress sensitivity than the wild type(WT). Ta PUB1 overexpression upregulated the expression of genes related to ion channels and increased the net root Na+efflux, but decreased the net K+efflux and H+influx, thereby maintaining a low cytosolic Na+/K+ratio, compared with the WT. However,RNAi-mediated knock-down plants showed the opposite response to salt stress. Ta PUB1 could induce the expression of some genes that improved the antioxidant capacity of plants under salt stress. Ta PUB1 also interacted with Ta MP(Triticum aestivum α-mannosidase protein), a regulator playing an important role in salt response in yeast and in plants. Thus, low cytosolic Na+/K+ratios and better antioxidant enzyme activities could be maintained in wheat with overexpression of Ta PUB1 under salt stress. Therefore, we conclude that the U-box E3 ubiquitin ligase Ta PUB1 positively regulates salt stress tolerance in wheat.Wenlong Wang Wenqiang Wang Yunzhen Wu Qinxue Li Guangqiang Zhang Ruirui Shi Junjiao Yang Yong Wang Wei Wang 2020Journal of Integrative Plant Biology2020,62,5:6

The passive Q-switch laser was also the first acquired with an average output power of 3.3 W and per pulse energy of 23.31 μJ, and the beam quality factors of M_x^2 = 1.06 and M_y^2 = 1.06 were measured at the average output power of 2 W.LINJUN LI XINING YANG LONG ZHOU WENQIANG XIE YUNLONG WANG YINGJIE SHEN YUQIANG YANG WENLONG YANG WEI WANG ZHIWEI LV XIAOMING DUAN MINGHUA CHEN 2018Photonics Research2018,6,6:5
15OsVP1 activates Sdr4 expression to control rice seed dormancy via the ABA signaling pathway显示文摘Pre-harvest sprouting(PHS)is a disadvantageous trait in cereal production worldwide,causing large economic losses each year.Its regulation mechanism is still unclear.We generated the Oryza sativa Viviparous1(OsVP1)mutant using gene editing technique,which shows increased PHS compared with that of the wild type Nipponbare.OsVP1 is localized mainly in the nucleus and expressed in various tissues and organs.Expression of Seed dormancy 4(Sdr4),a key gene controlling PHS,was sharply reduced in OsVP1 mutants.OsVP1 bound to the specific motif CACCTG in the promoter of Sdr4 and activated its expression in rice protoplasts.Overexpression of Sdr4 reduced the high seed germination rate of OsVP1 mutant cr-osvp1-1,showing that Sdr4 acts as a downstream target of OsVP1.Both OsVP1 and Sdr4 loss-of-function mutants were insensitive to exogenous ABA and employed the ABA signaling pathway in regulating seed dormancy.These findings shed light on the control of seed dormancy aimed at preventing PHS in rice.Wenqiang Chen Wei Wang Yusong Lyu Yawen Wu Pingliang Huang Shikai Hu Xiangjin Wei Guiai Jiao Zhonghua Sheng Shaoqing Tang Gaoneng Shao Ju Luo 2021The Crop Journal2021,9,1:5
16Trends in Incidence Rates,Mortality Rates,and Age-Period-Cohort Effects of Cervical Cancer—China,2003–2017显示文摘Introduction:This study reported the trends and analyzed the age-period-cohort effects on the incidence and mortality rates of cervical cancer in China.Methods:The age-standardized incidence rate(ASIR)and mortality rate(ASMR)by Segi’s world standard population were calculated using qualified consecutive data from 22 cancer registries from 2003 to 2017 in China.We performed joinpoint analysis to describe the trends and age-period-cohort analysis to estimate the independent effects of age,period and cohort on trends in incidence and mortality rates of cervical cancer.Results:The ASIR and ASMR for cervical cancer in females over 20 years old increased during 2003−2017.For females<50 years,a decreasing trend in ASIR and a stable trend in ASMR were observed in urban areas after 2009.But the ASIR and ASMR kept increasing in rural areas during the whole period.For females>50 years,the ASIR and ASMR increased both in urban and rural areas.Age-period-cohort analysis showed increasing period effects on cervical cancer incidence and mortality during the whole period.The cohort effects exhibited a downward-upwarddownward pattern for the incidence(1918–1938,1938–1963,1963–1993)and mortality rates(1918–1943,1943–1963,1963–1993)in urban areas,a fluctuating pattern for incidence rate and a continuing downward pattern for mortality rate(1918–1993)in rural areas.Conclusions:The increases in cervical cancer incidence and mortality rates can be mostly explained by period effects.We observed decreases in risk for cervical cancer incidence and mortality in young female generations,which were more obvious in urban areas.Kexin Sun Rongshou Zheng Lin Lei Siwei Zhang Hongmei Zeng Shaoming Wang Li Li Ru Chen Bingfeng Han Ji Peng Wenqiang Wei Jie He 2022China CDC weekly2022,4,48:4
17Overaccumulation of glycine betaine makes the function of the thylakoid membrane better in wheat under salt stress显示文摘Wheat(Triticum aestivum L.) lines T1, T4, and T6 were genetically modified to increase glycine betaine(GB) synthesis by introduction of the BADH(betaine aldehyde dehydrogenase, BADH)gene from mountain spinach(Atriplex hortensis L.). These transgenic lines and WT of wheat(T. aestivum L.) were used to study the effect of increased GB synthesis on wheat tolerance to salt stress. Salt stress due to 200 mmol L-1Na Cl impaired the photosynthesis of the four wheat lines, as indicated by declines in net photosynthetic rate(Pn), stomatal conductance(Gs),maximum photochemical efficiency of PSII(Fv/Fm), and actual photochemical efficiency of PSII(ФPSII) and an increase in intercellular CO2concentration(Ci). In comparison with WT, the effect of salinity on the three transgenic lines was mild. Salt stress caused disadvantageous changes in lipids and their fatty acid compositions in the thylakoid membrane of the transgenic lines and WT. Under salt stress, the three transgenic lines showed slightly higher chlorophyll and carotenoid contents and higher Hill reaction activities and Ca2+-ATPase activity than WT. All the results suggest that overaccumulation of GB resulting from introduction of the BADH gene can enhance the salt tolerance of transgenic plants, especially in the protection of the components and function of thylakoid membranes, thereby making photosynthesis better. Changes in lipids and fatty acid compositions in the thylakoid membrane may be involved in the increased salt stress tolerance of the transgenic lines.Fengxia Tian Wenqiang Wang Chao Liang Xin Wang Guiping Wang Wei Wang 2017The Crop Journal2017,5,1:4

19Signatures within esophageal microbiota with progression of esophageal squamous cell carcinoma显示文摘Objective: Esophageal squamous cell carcinoma(ESCC) is one of the dominant malignances worldwide, but currently there is less focus on the microbiota with ESCC and its precancerous lesions.Methods: Paired esophageal biopsy and swab specimens were obtained from 236 participants in Linzhou, China.Data from 16 S ribosomal RNA gene sequencing were processed using quantitative insights into microbial ecology(QIIME2) and R Studio to evaluate differences. The Wilcoxon rank sum test and Kruskal-Wallis rank sum test were used to compare diversity and characteristic genera by specimens and participant groups. Ordinal logistic regression model was used to build microbiol prediction model.Results: Microbial diversity was similar between biopsy and swab specimens, including operational taxonomic unit(OTU) numbers and Shannon index. There were variations and similarities of esophageal microbiota among different pathological characteristics of ESCC. Top 10 relative abundance genera in all groups include Streptococcus, Prevotella, Veillonella, Actinobacillus, Haemophilus, Neisseria, Alloprevotella, Rothia, Gemella and Porphyromonas. Genus Streptococcus, Haemophilus, Neisseria and Porphyromonas showed significantly difference in disease groups when compared to normal control, whereas Streptococcus showed an increasing tendency with the progression of ESCC and others showed a decreasing tendency. About models based on all combinations of characteristic genera, only taken Streptococcus and Neisseria into model, the prediction performance was the ideal one, of which the area under the curve(AUC) was 0.738.Conclusions: Esophageal biopsy and swab specimens could yield similar microbial characterization. The combination of Streptococcus and Neisseria has the potential to predict the progression of ESCC, which is needed to confirm by large-scale, prospective cohort studies.Minjuan Li Dantong Shao Jiachen Zhou Jianhua Gu Junjie Qin Wen Chen Wenqiang Wei 2020Chinese Journal of Cancer Research2020,32,6:4
20Experimental and numerical investigation on opposing plasma synthetic jet for drag reduction显示文摘Experimental and numerical studies are carried out to validate the potential of opposing Plasma Synthetic Jet(PSJ)for drag reduction for a hemisphere.Firstly,flow field changes of opposing PSJ are analyzed by comparing the experimental schlieren images and simulation results in a supersonic free stream of Mach number 3.As PSJ is a kind of unsteady pulsed jet,the shock standoff distance increases initially and then decreases under the control of PSJ,which corresponds to the change of the strength of PSJ.Accordingly,the amount of drag reduction of the hemisphere increases initially and then decreases.It is found that there is a short period of“drag rise”during the formation of PSJ before the drag reduction,which is induced by the generation of normal shock waves and the area difference of the cavity wall of PSJ Actuator(PSJA).Secondly,the effects of five parameters,including exit diameter,discharge energy of PSJA,Mach number,static pressure of incoming flow and angle of attack,on drag reduction of opposing PSJ were studied in detail by using numerical method.It is found that the Maximum Pressure Ratio(MPR)has a significant impact on the average drag reduction for a configuration-determined PSJA.For the configuration selected in this study,the flow field of opposing PSJ shows typical Short Penetration Mode(SPM)in a control cycle of PSJ when the MPR is less than 0.89.However,the flow field shows typical Long Penetration Mode(LPM)at some time when the MPR is bigger than 0.89.Relatively better drag reduction is achieved in this case.Wei XIE Zhenbing LUO Yan ZHOU Wenqiang PENG Qiang LIU Dengpan WANG 2022Chinese Journal of Aeronautics2022,35,8:4
