| 1 | Current status of diagnosis and treatment of bladder cancer in China-Analyses of Chinese Bladder Cancer Consortium database显示文摘Objective:To investigate current status of diagnosis and treatment of bladder cancer in China.Methods:A database was generated by Chinese Bladder Cancer Consortium(CBCC).From January 2007 to December 2012,14,260 cases from 44 CBCC centers were included.Data of diagnosis,treatment and pathology were collected.Results:The average age was 63.5 year-old and most patients were male(84.3%).The most common histologic types were urothelial carcinoma(91.4%),adenocarcinoma(1.8%),and squamous carcinoma(1.9%).According to 1973 and 2004 WHO grading system,42.0%,41.0%,and 17.0% of patients were grade 1,2,and 3,and 16.0%,48.7%,and 35.3% of patients were papillary urothelial neoplasms of low malignant potential,low,and high grade,respectively.Non-muscle invasive bladder cancer(NMIBC)and muscle invasive bladder cancer(MIBC)were 25.2% and 74.1%,respectively(0.8% not clear).Carcinoma in situ was only 2.4%.Most patients were diagnosed by white-light cystoscopy with biopsy(74.3%).Fluorescence and narrow band imaging cystoscopy had additional detection rate of 1.0% and 4.0%,respectively.Diagnostic transurethral resection(TUR)provided detection rate of 16.9%.Most NMIBCs were treated with TUR(89.2%).After initial TUR,2.6%accepted second TUR,and 45.7%,69.9%,and 58.7% accepted immediate,induced,and maintenance chemotherapy instillation,respectively.Most MIBCs were treated with radical cystectomy(RC,59.7%).Laparoscopic RCs were 35.1%,while open RC 63.4%.Extended and standard pelvic lymph node dissection were 7% and 66%,respectively.Three most common urinary diversions were orthotopic neobladder(44%),ileal conduit(31%),and ureterocutaneostomy(23%).Only 2.3% of patients accepted neo-adjuvant chemotherapy and only 18%of T3 and T4 patients accepted adjuvant chemotherapy.Conclusion:Disease characteristics are similar to international reports,while differences of diagnosis and treatment exist.This study can provide evidences for revisions of the guideline on bladder cancer in China. | Kaiwen Li Tianxin Lin 无 Wei Xue Xin Mu Enci Xu Xu Yang Fubao Chen Guangyong Li Lulin Ma Guoliang Wang Chaozhao Liang Haoqiang Shi Ming Li Mao Tang Xueyi Xue Yisong Lv Yaoliang Deng Chengyang Li Zhiwen Chen Xiaozhou Zhou Fengshuo Jin Xudong Liu Jinxin Wei Lei Shi Xin Gou Weiyang He Liqun Zhou Lin Cai Baiye Jin Guanghou Fu Xiangbo Kong Hongyan Sun Ye Tian Lang Feng Tiejun Pan Yiyi Wu Dongwen Wang Hailong Hao Benkang Shi Yaofeng Zhu Qiang Wei Ping Han Changli Wu Dawei Tian Zhangqun Ye Zheng Liu Zhiping Wang Junqiang Tian Lin Qi Minfeng Chen Wei Li Jinchun Qi Gongxian Wang Longlong Fu Zhaolin Sun Guangheng Luo Zhoujun Shen Zhaowei Zhu Jinchun Xing Zhun Wu Dong Wei Xin Chen Yanqun Na Hongfeng Guo Chunxi Wang Zhihua Lu Chuize Kong Yang Liu Jin Yang Jianyun Hu Xin Gao Jielin Li Changjun Yin Pu Li Shan Chen Zhen Du Jiongming Li Yongji Yan Xu Zhang Shuang Huang Fangjian Zhou Zhiling Zhang Yinghao Sun Shuxiong Zeng Song Cen Jiaquan Zhou Hanzhong Li Jin Wen Jian Huang | 2015 | Asian Journal of Urology2015,2,2: | 21 |
| 2 | Effect of Deficit Irrigation on the Growth, Water Use Characteristics and Yield of Cotton in Arid Northwest China显示文摘Water shortage is a key constraint to sustainable agricultural production in Xinjiang, Northwest China. To enhance the use efficiency of valuable irrigation water resources, a 2-year experiment(2010–2011) was conducted to quantify the response of cotton(Gossypium hirsutum L.) growth and yield to different degrees of deficit irrigation(DI) regimes; to determine the effects of DI on the characteristics of water use for cotton, seasonal water use, available soil water in the root zone, soil water depletion, evapotranspiration(ET)-based water use efficiency and irrigation-based water use efficiency, and to determine the best DI regime for optimal water-saving and yield output. The plots were irrigated at 100%(100ET), 85%(85ET), 70%(70ET), 55%(55ET) and 45%(45ET) of the regional ET of cotton in northern Xinjiang. The effect of DI irrigation on water use characteristics was evaluated by analyzing available soil water and soil water depletion in the root zone along with water use efficiencies of cotton. The study showed that the growth, water use characteristics and yield of cotton varied with irrigation regime. Seasonal ET and seed cotton yield were linearly correlated with irrigation amount. The second-order polynomial equation best approximated water-yield relationship of cotton in the study area.Cotton yield response factor was 0.65, suggesting limited water conditions were suitable for cotton cultivation. Economic evaluation of DI treatments confirmed that the yield loss was less than 10% under 70 ET and 85 ET, which was acceptable for greater sustainability.The results suggested that proper DI schemes were necessary for sustainable cotton production in the region. While irrigation at 85 ET was safe for high cotton yield, irrigation at 70 ET was a viable alternative under limited irrigation water availability. | YANG Chuanjie LUO Yi SUN Lin WU Na | 2015 | Pedosphere2015,25,6: | 17 |
| 3 | BH3-only proteins target BCL-xL/MCL-1,not BAX/BAK,to initiate apoptosis显示文摘It has been widely accepted that mitochondria-dependent apoptosis initiates when select BH3-only proteins(BID,BIM,etc.)directly engage and allosterically activate effector proteins BAX/BAK.Here,through reconstitution of cells lacking all eight pro-apoptotic BH3-only proteins,we demonstrate that all BH3-only proteins primarily target the anti-apoptotic BCL-2 proteins BCL-xL/MCL-1,whose simultaneous suppression enables membrane-mediated spontaneous activation of BAX/BAK.BH3-only proteins*apoptotic activities correlate with affinities for BCL-xL/MCL1 instead of abilities to directly activate BAX/BAK.Further,BID and BIM do not distinguish BAX from BAK or accelerate BAX/BAK activation following inactivation of BCL-xL/MCL-1.Remarkably,death ligandinduced apoptosis in cells lacking BH3-only proteins and MCL-1 is fully restored by BID mutants capable of neutralizing BCL-xL,but not direct activation of BAX/BAK.Taken together,our findings provide a'Membrane-mediated Permissive'model,in which the BH3-only proteins only indirectly activate BAX/BAK by neutralizing the anti-apoptotic BCL-2 proteins,and thus allowing BAX/BAK to undergo unimpeded,spontaneous activation in the mitochondrial outer membrane milieu,leading to apoptosis initiation. | Kai Huang Katelyn L.O'Neill Jian Li Wei Zhou Na Han Xiaming Pang Wei Wu Lucas Struble Gloria Borgstahl Zhaorui Liu Liqiana Zhang Xu Luo | 2019 | Cell Research2019,29,11: | 16 |
| 4 | Colorectal cancer incidence and mortality:the current status,temporal trends and their attributable risk factors in 60 countries in 2000–2019显示文摘Background:Globally,colorectal cancer(CRC)imposes a substantial burden on healthcare systems and confers considerable medical expenditures.We aimed to evaluate the global and regional burden in epidemiological trends and factors associated with the incidence and mortality of CRC.Methods:We used data from the GLOBOCAN database to estimate CRC incidence and mortality worldwide in 2020 and their association with the human development index(HDI).Trends of age-standardized rates of incidence and mortality in 60 countries(2000–2019)were evaluated by Joinpoint regression analysis using data of Global Burden of Disease 2019.The association between exposure to country-level lifestyle,metabolic and socioeconomic factors obtained from the World Health Organization Global Health Observatory and World Bank DataBank data and CRC incidence and mortality was determined by multivariable linear regression.Results:CRC incidence and mortality varied greatly in the 60 selected countries,and much higher incidence and mortality were observed in countries with higher HDIs,and vice versa.From 2000 to 2019,significant increases of incidence and mortality were observed for 33 countries(average annual percent changes[AAPCs],0.24–3.82)and 18 countries(AAPCs,0.41–2.22),respectively.A stronger increase in incidence was observed among males(AAPCs,0.36–4.54)and individuals<50 years(AAPCs,0.56–3.86).Notably,15 countries showed significant decreases in both incidence(AAPCs,0.24 to2.19)and mortality(AAPCs,0.84 to2.74).A significant increase of incidence among individuals<50 years was observed in 30 countries(AAPCs,0.28–3.62).Countries with higher incidence were more likely to have a higher prevalence of alcohol drinking,higher level of cholesterol level,higher level of unemployment,and a poorer healthcare system.Conclusions:Some high-HDI countries showed decreasing trends in CRC incidence and mortality,whereas developing countries that previously had low disease burden showed significantly increased incidence and mortality trends,especially in males and populations≥50 years,which require targeted preventive health programs. | Bin Lu Na Li Chen-Yu Luo Jie Cai Ming Lu Yu-Han Zhang Hong-Da Chen Min Dai | 2021 | Chinese Medical Journal2021,,16: | 13 |
| 5 | Impacts of Types and Degree of Obesity on Non-Alcoholic Fatty Liver Disease and Related Dyslipidemia in Chinese School-Age Children?显示文摘Objective To explore the impacts of types and degree of obesity on non‐alcoholic fatty liver disease (NAFLD) and related lipids disturbance in Chinese school‐age children. Methods A total of 1 452 school‐age Children of 7 to 17 years were recruited in Beijing with representative cluster sampling method. Data of anthropometric measurements including weight, height and waist circumference were collected from March to May of 2007. Body mass index(BMI)was calculated. Blood samples were obtained and lipid profiles including triglyceride (TG), total cholesterol (TC), high‐density lipoprotein cholesterol (HDL‐C) and low‐density lipoprotein cholesterol (LDL‐C) were measured, while glutamate‐pyruvate transaminase (ALT) and glutamic‐oxalacetic transaminase (AST) were determined to evaluate liver function. The liver was also scanned by sonography, and abnormal hepatic sonograms were documented. NAFLD was diagnosed according to the criteria recommended by the Fatty Liver and Alcoholic Liver Disease Study Group under the Chinese Liver Disease Association. Analysis of covariance (ANOVA), Chi‐square test for trend and binary logistic regression analysis were performed. Results The dyslipidemia and ultrasonographic fatty liver deteriorated with the degree of obesity defined either by BMI or waist circumference. Compared with BMI, waist circumference contributed more to the development of dyslipidemia, fatty liver and NAFLD. The highest levels of TG, TC, LDL‐C, and lowest level of HDL‐C were seen in the mixed obese group followed by abdominal obese, peripheral obese and non‐obese ones. Adjusted for gender and age, the odds ratios (ORs) and their 95% confidence intervals of peripheral obesity, abdominal obesity and mixed obesity were 0, 10.93 (0.98‐121.96) and 79.16 (10.95‐572.44) for predicting NAFLD; 12.61 (1.24‐127.78), 19.39 (5.23‐71.85), and 93.21 (29.56‐293.90) for predicting ultrasonographic fatty liver; 1.78 (0.59‐5.44), 3.01 (1.91‐4.77), and 4.64 (3.52‐6.12) for predicting dyslipidemia, respectively compared with the non‐obese control group. The trend of hazards over groups was statistically significant (P<0.01). Conclusion The levels of lipid profile and the prevalence of NAFLD and dyslipidemia increased in parallel with the degree of obesity; As compared with the non‐obese control, the mixed obesity had the strongest association with NAFLD and dyslipidemia, followed by abdominal obesity and peripheral obesity in Chinese school‐age Children. | MENG LingHui LUO Na MI Jie | 2011 | Biomedical and Environmental Sciences2011,24,1: | 13 |
| 6 | Enhanced absorption and inhibited metabolism of emodin by 2,3,5,4'-tetrahydroxystilbene-2-O-β-D-glucopyranoside: Possible mechanisms for Polygoni Multiflori Radix-induced liver injury显示文摘Polygoni Multiflori Radix(PMR) has been commonly used as a tonic in China for centuries. However, PMR-associated hepatotoxicity is becoming a safety issue. In our previous in vivo study, an interaction between stilbenes and anthraquinones has been discovered and a hypothesis is proposed that the interaction between stilbene glucoside-enriching fraction and emodin may contribute to the side effects of PMR. To further support our previous in vivo results in rats, the present in vitro study was designed to evaluate the effects of 2, 3, 5, 4'-tetrahydroxystilbene-2-O-β-D-glucopyranoside(TSG) on the cellular absorption and human liver microsome metabolism of emodin. The obtained results indicated that the absorption of emodin in Caco-2 cells was enhanced and the metabolism of emodin in human liver microsomes was inhibited after TSG treatment. The effects of the transport inhibitors on the cellular emodin accumulation were also examined. Western blot assay suggested that the depressed metabolism of emodin could be attributed to the down-regulation of UDP-glucuronosyltransferases(UGTs) 1A8, 1A10, and 2B7. These findings definitively demonstrated the existence of interaction between TSG and emodin, which provide a basis for a better understanding of the underlying mechanism for PMR-induced liver injury. | YU Qiong JIANG Li-Long LUO Na FAN Ya-Xi MA Jiang LI Ping LI Hui-Jun | 2017 | Chinese Journal of Natural Medicines2017,15,6: | 12 |
| 7 | Clinical Efficacy of Toric Orthokeratology in Myopic Adolescent with Moderate to High Astigmatism显示文摘Purpose:.To observe the efficacy of toric design orthokeratology.(ortho-k).for correcting myopia and astigmatism in myopic adolescents with moderate to high astigmatism.Methods:.This was a self-controlled clinical study..Twentyfour subjects(42 eyes).aged 9 to 16 years with myopia of 2.50-6.00 D complicated with rule astigmatism of 1.50-3.50 D were fitted with Lucid Night Toric Ortho-k Lenses(LUCID,KOREA)..The changes in uncorrected visual acuity(UCVA),spherical degree, refraction, axial length(AL),.and corneal status were assessed at baseline, 1 night, 1 week, 1 month, 3months, 6 months, and 1 year after the commencement of ortho-k lens wear.Results: The success rate of the first lens fit was 92.8%. The UCVA after ortho-k wearing was improved significantly compared to the baseline during each visit(all P<0.01), and became stable 1 month after ortho-k. The manifest myopia was significantly reduced from(-3.41±1.27) D to(-0.41±0.37) D by toric ortho-k and the degree of astigmatism from(-1.81±0.53)D to(-0.41±0.39) D after 1 month of lens wear(P<0.01).The mean AL was(24.47 ±0.91) mm at baseline, which did not significantly differ from(24.49 ±0.87) mm and(24.48 ±0.94) mm after 6 months and l year,.respectively,.of lens wear(both P >0.05)..Grade 1 corneal staining was observed at 1week(23.8%),.1 month(21.4%), and 1 year(16.7%) following lens wear, and was improved by lens cleaning,.discontinuing lens wear, and moistening the cornea with eye drops.No severe adverse events were reported.Conclusion: The toric ortho-k lens was effective and safe for correction of low to moderate myopia in children with moderate to high astigmatism..The lens also effectively controlled axial length elongation during 1 year of observation..However,the long-term efficacy remains to be elucidated. | Ming Luo Shengsheng Ma Na Liang | 2014 | Eye Science2014,29,4: | 12 |
| 8 | Insight-HXMT observations of the first binary neutron star merger GW170817显示文摘Finding the electromagnetic(EM) counterpart of binary compact star merger, especially the binary neutron star(BNS) merger,is critically important for gravitational wave(GW) astronomy, cosmology and fundamental physics. On Aug. 17, 2017,Advanced LIGO and Fermi/GBM independently triggered the first BNS merger, GW170817, and its high energy EM counterpart,GRB 170817 A, respectively, resulting in a global observation campaign covering gamma-ray, X-ray, UV, optical, IR, radio as well as neutrinos. The High Energy X-ray telescope(HE) onboard Insight-HXMT(Hard X-ray Modulation Telescope) is the unique high-energy gamma-ray telescope that monitored the entire GW localization area and especially the optical counterpart(SSS17 a/AT2017 gfo) with very large collection area(~1000 cm^2) and microsecond time resolution in 0.2-5 MeV. In addition,Insight-HXMT quickly implemented a Target of Opportunity(ToO) observation to scan the GW localization area for potential X-ray emission from the GW source. Although Insight-HXMT did not detect any significant high energy(0.2-5 MeV) radiation from GW170817, its observation helped to confirm the unexpected weak and soft nature of GRB 170817 A. Meanwhile,Insight-HXMT/HE provides one of the most stringent constraints(~10^(-7) to 10^(-6) erg/cm^2/s) for both GRB170817 A and any other possible precursor or extended emissions in 0.2-5 MeV, which help us to better understand the properties of EM radiation from this BNS merger. Therefore the observation of Insight-HXMT constitutes an important chapter in the full context of multi-wavelength and multi-messenger observation of this historical GW event. | TiPei Li ShaoLin Xiong ShuangNan Zhang FangJun Lu LiMing Song XueLei Cao Zhi Chang Gang Chen Li Chen TianXiang Chen Yong Chen YiBao Chen YuPeng Chen Wei Cui WeiWei Cui JingKang Deng YongWei Dong YuanYuan Du MinXue Fu GuanHua Gao He Gao Min Gao MingYu Ge YuDong Gu Ju Guan ChengCheng Guo DaWei Han Wei Hu Yue Huang Jia Huo ShuMei Jia LuHua Jiang WeiChun Jiang Jing Jin YongJie Jin Bing Li ChengKui Li Gang Li MaoShun Li Wei Li Xian Li XiaoBo Li XuFang Li YanGuo Li ZiJian Li ZhengWei Li XiaoHua Liang JinYuan Liao CongZhan Liu GuoQing Liu HongWei Liu ShaoZhen Liu XiaoJing Liu Yuan Liu YiNong Liu Bo Lu XueFeng Lu Tao Luo Xiang Ma Bin Meng Yi Nang JianYin Nie Ge OU JinLu Qu Na Sai Liang Sun Yin Tan Lian Tao WenHui Tao YouLi Tuo GuoFeng Wang HuanYu Wang Juan Wang WenShuai Wang YuSa Wang XiangYang Wen BoBing WU Mei Wu GuangCheng Xiao He Xu YuPeng Xu LinLi Yan JiaWei Yang Sheng Yang YanJi Yang AiMei Zhang ChunLei Zhang ChengMo Zhang Fan Zhang HongMei Zhang Juan Zhang Qiang Zhang Shu Zhang Tong Zhang Wei Zhang WanChang Zhang WenZhao Zhang Yi Zhang Yue Zhang YiFei Zhang YongJie Zhang Zhao Zhang ZiLiang Zhang HaiSheng Zhao JianLing Zhao XiaoFan Zhao ShiJie Zheng Yue Zhu YuXuan Zhu ChangLin Zou | 2018 | Science China(Physics,Mechanics & Astronomy)2018,61,3: | 12 |

| 10 | A heavy mineral viewpoint on sediment provenance and environment in the Qiongdongnan Basin显示文摘Based on heavy mineral data in core samples from eleven drillings, supplemented by paleontological, element geochemical and seismic data, the evolution of sediment provenance and environment in the Qiongdongnan Basin(QDNB) was analysed. The results show that the basement in the QDNB was predominantly composed of terrigenous sediments. Since the Oligocene the QDNB has gradually undergone transgressions and evolution processes in sedimentary environment from terrestrial-marine transitional to littoral-neritic, neritic, and bathyal roughly. The water depth showed a gradually increasing trend and was generally greater in the southern region than that in the northern region in the same time. With changes in sedimentary environment, provenances of the strata(from the Yacheng Formation to the Yinggehai Formation) showed principal characteristics of multisources, evolving from autochthonous source, short source to distant source step by step. During the Early Oligocene, the sediments were mainly proximal basaltic pyroclastic source and adjacent terrigenous clastic source, afterwards were becoming distant terrigenous clastic sources, including Hainan Island on the north,Yongle Uplift on the south, Shenhu Uplift on the northeast, the Red River System on the northwest and Indochina Peninsula on the southwest, or even a wider region. The Hainan Island provenance began to develop during the Early Oligocene and has become a main provenance in the QDNB since the Middle Miocene. The provenances from Yongle Uplift and Shenhu Uplift most developed from the Late Oligocene to the Early Miocene and gradually subsided during the Middle Miocene. During the Late Miocene, as a main source of sediments filled in the central canyon, the Red River System provenance added to the QDNB massively, whose impact terminated at the end of the Pliocene. The western Yinggehai Basin(YGHB) provenance derived from Indochina Peninsula had developed from the Pliocene on to the Pleistocene. In addition, the material contribution of marine authigenous source to the basin(especially to the southern region) could not be ignored. | LIU Xiaofeng ZHANG Daojun ZHAI Shikui LIU Xinyu CHEN Hongyan LUO Wei LI Na XIU Chun | 2015 | Acta Oceanologica Sinica2015,34,4: | 10 |
| 11 | A Geometric Understanding of Deep Learning显示文摘This work introduces an optimal transportation(OT)view of generative adversarial networks(GANs).Natural datasets have intrinsic patterns,which can be summarized as the manifold distribution principle:the distribution of a class of data is close to a low-dimensional manifold.GANs mainly accomplish two tasks:manifold learning and probability distribution transformation.The latter can be carried out using the classical OT method.From the OT perspective,the generator computes the OT map,while the discriminator computes the Wasserstein distance between the generated data distribution and the real data distribution;both can be reduced to a convex geometric optimization process.Furthermore,OT theory discovers the intrinsic collaborative-instead of competitive-relation between the generator and the discriminator,and the fundamental reason for mode collapse.We also propose a novel generative model,which uses an autoencoder(AE)for manifold learning and OT map for probability distribution transformation.This AE–OT model improves the theoretical rigor and transparency,as well as the computational stability and efficiency;in particular,it eliminates the mode collapse.The experimental results validate our hypothesis,and demonstrate the advantages of our proposed model. | Na Lei Dongsheng An Yang Guo Kehua Su Shixia Liu Zhongxuan Luo Shing-Tung Yau Xianfeng Gu | 2020 | Engineering2020,6,3: | 10 |
| 12 | A Low-Complexity PTS Based on Greedy and Genetic Algorithm for OFDM Systems显示文摘Partial transmit sequence(PTS) is one of effective technique to reduce high Peak-to-average power ratio(PAPR) in Orthogonal frequency division multiplexing(OFDM) system. However, the complexity of Original PTS(O-PTS) increases exponentially with the number of sub-blocks. To reduce the computational complexity while still offering a lower PAPR, a new PTS method is proposed to search for suboptimal rotating vectors in this paper. In the proposed method, the candidate rotation vectors are generated based on greedy and genetic algorithm.We also combine the proposed method and the superimposed training sequence method to get a further PAPR reduction. The theory and simulations results show that the proposed method can achieve better PAPR reduction and significantly reduce the computational complexity. | LUO Renze ZHANG Chengsen NIU Na LI Rui | 2015 | Chinese Journal of Electronics2015,24,4: | 10 |
| 13 | On the mechanical behavior of the human biliary system显示文摘This paper reviews the progress made in understanding the mechanical behaviour of the biliary system. Gallstones and diseases of the biliary tract affect more than 10% of the adult population. The complications of gallstones, i.e. acute pancreatitis and obstructive jandice, can be lethal, and patients with acalculous gallbladder pain often pose diagnostic difficulties and undergo repeated ultrasound scans and oral cholecystograms. Moreover, surgery to remove the gallbladder in these patients, in an attempt to relieve the symptoms, gives variable results. Extensive research has been carried out to understand the physiological and pathological functions of the biliary system, but the mechanism of the pathogenesis of gallstones and pain production still remain poorly understood. It is believed that the mechanical factors play an essential role in the mechanisms of the gallstone formation and biliary diseases. However, despite the extensive literature in clinical studies, only limited work has been carried out to study the biliary system from the mechanical point of view. In this paper, we discuss the state of art knowledge of the fluid dynamics of bile flow in the biliary tract, the solid mechanics of the gallbladder and bile ducts, recent mathematical and numerical modelling of the system, and finally the future challenges in the area. | Xiaoyu Luo Wenguang Li Nigel Bird Swee Boon Chin NA Hill Alan G Johnson | 2007 | World Journal of Gastroenterology2007,13,9: | 9 |
| 14 | MicroRNA Expression Signature in Gastric Cancer显示文摘Objective:To identify the miRNA specific signature as novel diagnostic and prognostic tools for gastric cancer. Methods:miRNAs expression profiling of 3 normal gastric tissues,24 malignant tissues,gastric cancer cell SGC7901 and normal gastric cell GES-1 were detected using microarray technology. The hierarchical clustering algorithm of the Cluster software was used to analyse the miRNAs expression of all samples. The expression levels of miR-433 and miR-9 which were significantly down-regulated in gastric cancer tissues and SGC7901 cells by microarray technology were validated by quantitative Real-time PCR(qRT-PCR). Results:Differential expressions of 26 individual miRNAs between normal samples(including 3 normal gastric tissues and GES-1 cells) and carcinomas(including 24 malignant tissues and SGC7901 cells) were discovered,19 of them showing down-regulation and 7 up-regulation in carcinoma samples. Hierarchical clustering of the cancer samples by their miRNA expression accurately separated the carcinomas from normal samples and further their histotypes of carcinomas. The expression levels of miR-433 and miR-9 were significantly down-regulated in gastric cancer tissues and SGC7901cells Conclusion:The differential expression of miR-433 and miR-9 may be used as a novel diagnostic tool for gastric cancer. | Hong-chun Luo Zhen-zhen Zhang Xia Zhang Bo Ning Jin-jun Guo Na Niel Bo Liu Xiao-ling Wu | 2009 | Chinese Journal of Cancer Research2009,21,1: | 9 |
| 15 | Geochemical characteristics and their significances of rare-earth elements in deep-water well core at the Lingnan Low Uplift Area of the Qiongdongnan Basin显示文摘A geochemical analysis of rare-earth elements(REEs) in 97 samples collected from the core of deep-water Well LS-A located at the Lingnan Low Uplift Area of the Qiongdongnan Basin is conducted, with the purpose of revealing the changes of sedimentary source and environment in the study region since Oligocene and evaluating the response of geochemical characteristics of REEs to the tectonic evolution. In the core samples, both ∑REE and ∑LREE(LREE is short for light-group REEs) fluctuate in a relatively wide range, while ∑HREE(HREE is short for heavy-group REEs) maintains a relatively stable level. With the stratigraphic chronology becoming newer, both ∑REE and ∑LREE show a gradually rising trend overall. The ∑REE of the core is relatively high from the bottom of Yacheng Formation(at a well depth of 4 207 m) to the top of Ledong Formation, and the REEs show partitioning characteristics of the enrichment of LREE, the stable content of HREE, and the negative anomaly of Eu to varying degrees. Overall the geochemical characteristics of REEs are relatively approximate to those of China's neritic sediments and loess, with significant 'continental orientation'. The ∑REE of the core is relatively low in the lower part of Yacheng Formation(at a well depth of 4 207–4 330 m), as shown by the REEs partitioning characteristics of the depletion of LREE, the relative enrichment of HREE, and the positive anomaly of Eu; the geochemical characteristics of REEs are approximate to those of oceanic crust and basalt overall, indicating that the provenance is primarily composed of volcanic eruption matters. As shown by the analyses based on sequence stratigraphy and mineralogy, the provenance in study region in the early Oligocene mainly resulted from the volcanic materials of the peripheral uplift areas; the continental margin materials from the north contributed only insignificantly; the provenance developed to a certain extent in the late Oligocene. Since the Miocene, the provenance has ceaselessly expanded from proximal to distal realm, embodying a characteristic of multi-source sedimentation. In the core strata with 31.5, 28.4, 25.5, 23, and 16 Ma from today, the geochemical parameters of REEs and Th/Sc ratio have significant saltation, embodying the tectonic movement events in the evolution of the Qiongdongnan Basin.

| 17 | Regulatory mechanism of hormones of the pituitary-target gland axes in kidney-Yang deficiency based on a support vector machine model显示文摘OBJECTIVE:To study the development mechanism of kidney-Yang deficiency through the establishment of support vector machine models of relevant hormones of the pituitary-target gland axes in rats with kidney-Yang deficiency syndrome.METHODS:The kidney-Yang deficiency rat model was created by intramuscular injection of hydrocortisone,and contents of the hormones of the pituita- ry-thyroid axis:thyroid stimulating hormone(TSH),3,3',5-triiodothyronine(T_3) and thyroxine(T_4);hormones of the pituitary-adrenal gland axis:adrenocorticotropic hormone(ACTH) and Cortisol(CORT);and hormones of the pituitary-gonadal axis:luteinizing hormone(LH),follicle-stimulating hormone(FSH),and testosterone(T),were determined in the early,middle,and advanced stages.Ten support vector regression(SVR) models of the hormones were established to analyze the mutual relationships among the hormones of the three axes.RESULTS:The feedback control action of the pituitary-adrenal axis began to lose efficacy from the middle stage of kidney-Kong deficiency.The contents all hormones of the three pituitary-target gland axes decreased in the advanced stage.Relative errors of the jackknife test of the SVR models all were less than 10%.CONCLUSION:Imbalances in mutual regulation among the hormones of the pituitary-target gland axes,especially loss of effectiveness of the pituitary-adrenal axis,is one pathogenesis of kidney-Yang deficiency.The SVR model can accurately reflect the complicated non-linear relationships among pituitary-target gland axes in rats with of kidney-Yang deficiency. | Wang Xiufeng Zhang Lei Huang Rongbo Wu Qinghua Min Jianxin Ma Na Luo Laicheng | 2015 | Journal of Traditional Chinese Medicine2015,35,2: | 7 |
| 18 | miR-137 inhibits melanoma cell proliferation through downregulation of GLO1显示文摘Late-stage melanoma is refractory to current therapies. MicroRNAs (miRNAs) can modulate many physiological and pathological processes of melanoma. Studies have demonstrated that miR-137 acts as a tumor suppressor by inhibiting the proliferation of melanoma cells through targeting multiple mRNAs. The glyoxalase system member glyoxalase 1 (GLO1) is the principal scavenging enzyme of methylglyoxal (MG), a toxic byproduct of glycolysis. Using 35S in vivo/vitro labelling analysis for dynamic proteomics (SiLAD), we found that miR-137 downregulated the expression of GLO1 in melanoma cells.Bioinformatics analysis predicted that GLO1 is a direct target of miR-137. This was validated by dual luciferase reporter assay.Quantitative RT-PCR (qRT-PCR) and western blot analysis indicated that miR-137 could decrease endogenous GLO1 expression.Furthermore, siRNA targeting of GLO1 mimicked inhibition of melanoma cell proliferation caused by miR-137 overexpression.Re-expression of GLO1 was able to restore miR-137-mediated suppression of melanoma cell proliferation. Therefore, these results suggest that miR-137 inhibits the proliferation of melanoma cells by targeting GLO1. | Na Lv Shuai Hao Chonglin Luo Alia Abukiwan Ying Hao Fei Gai Weiwei Huang Lingyun Huang Xueyuan Xiao Stefan B.Eichmüller Dacheng He | 2018 | Science China(Life Sciences)2018,61,5: | 7 |
| 19 | Wide-steering-angle high-resolution optical phased array显示文摘Optical phased array(OPA)technology is considered a promising solution for solid-state beam steering to supersede the traditional mechanical beam steering.As a key component of the LIDAR system for long-range detection,OPAs featuring a wide steering angle and high resolution without beam aliasing are highly desired.However,a wide steering range requires a waveguide pitch less than half of the wavelength,which is easily subjected to cross talk.Besides,high resolution requires a large aperture,and it is normally achieved by a high count number of waveguides,which complicates the control system.To solve the mentioned issues,we design two high-performance 128-channel OPAs fabricated on a multilayered SiN-on-SOI platform.Attributed to the nonuniform antenna pitch,only 128 waveguides are used to achieve a 4 mm wide aperture.Besides,by virtue of innovative dual-level silicon nitride(Si_(3)N_(4))waveguide grating antennas,the fishbone antenna OPA achieves a 100°×19.4°field of view(FOV)with divergence of 0.021°×0.029°,and the chain antenna OPA realizes a 140°×19.23°FOV with divergence of 0.021°×0.1°.To our best knowledge,140°is the widest lateral steering range in two-dimensional OPA,and 0.029°is the smallest longitudinal divergence.Finally,we embed the OPA into a frequency-modulated continuous-wave system to achieve 100 m distance measurement.The reflected signal from 100 m distance is well detected with 26 dBm input transmitter power,which proves that OPA serves as a promising candidate for transceiving optical signal in a LIDAR system. | YINGZHI LI BAISONG CHEN QUANXIN NA QIJIE XIE MIN TAO LANXUAN ZHANG ZIHAO ZHI YUXUAN LI XIAOBIN LIU XIANSHU LUO GUOQIANG LO FENGLI GAO XUEYAN LI JUNFENG SONG | 2021 | Photonics Research2021,9,12: | 7 |
