| 1 | Expression of vascular endothelial growth factor and its receptors KDR and Fit-1 in gastric cancer cells显示文摘AIM: The expression of vascular endothelial growth factor (VEGF) and its receptors KDR and Flt-1 by gastric carcinoma tissues and different gastric carcinoma cell lines was detected to elucidate the molecular mechanism of this growth factor in promoting tumor growth.METHODS: The expression of VEGF, Flt-1 and KDR was determined by reverse transcription-polymerase chain reaction (RT-PCR) in gastric cancer cell lines RF-1, RF-48,AGS-1, NCI-N87, NCI-SNU-1, NCI-SNU-5, NCI-SNU-16 and KATO-Ⅲ. The expression of Flt-1 and KDR in paraffinembedded specimens of gastric cancer was determined by immunohistochemistry. The 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay was used to assess the role of VEGF in tumor cell proliferation.RESULTS: All 8 gastric cancer cell lines analyzed expressed VEGF121 and VEGF16s and six of them expressed both Flt-1 and KDR, while cell line NCI-SNU-5 expressed Flt-1 only and cell line KATOⅢ expressed neither Flt-1 nor KDR. The gastric carcinoma tissues expressed Flt-1 and KDR widely,with the positive rate of expression of Flt-1 and KDR being 84.6 % and 70 % respectively. The exogenous VEGF stimulated the growth of KDR-positive cell lines NCI-N87 and AGS-1 in a dose-dependent manner but exhibited no effect on the growth of KDR-negative cell line NCI-N87.CONCLUSION: VEGF and its receptors KDR and Flt-1 were expressed widely in gastric carcinoma cells and the VEGF stimulated KDR-positive tumor cell growth directly. These results suggest that VEGF may play a role in promoting tumor growth and metastasis by participating in both paracrine and autocrine pathways. | Hua Zhang Jian Wu Lin Meng Cheng-Chao Shou,Peking University School ofOncology,Beij ing Institute for Cancer Research,Beijing 100034,China | 2002 | World Journal of Gastroenterology2002，8，6： | 69 |

| 3 | Oral berberine improves brain dopa/dopamine levels to ameliorate Parkinson’s disease by regulating gut microbiota显示文摘The phenylalanine-tyrosine-dopa-dopamine pathway provides dopamine to the brain.Iin this process,tyrosine hydroxylase(TH)isthe rate-limiting enzyme that hydroxylates tyrosine and generates levodopa(L-dopa)with tetranydrobiopterin(BH_(4))as a coenzyme.Here,we show that oral berberine(BBR)might supply H^(·) through dihydroberberine(reduced BBR produced by bacterial nitroreductase)and promote the production of BHl from dihydrobiopterin;the increased BH,enhances TH activity,which accelerates the production of L-dopa by the gut bacteria.Oral BBR acts in a way similar to vitamins.The L-dopa produced by theintestinal bacteria enters the brain through the circulation and is transformed to dopamine.To verify the gut-brain dialog activatedby BBR's effect,Enterococcus foecalis or Enterococcus faecium was transplanted into Parkinson's disease(PD)mice.The bacteriasignificantly increased brain dopamine and ameliorated PD manifestation in mice;additionally,combination of BBR with bacteriashowed better therapeutic effect than that with bacteria alone.Moreover,2,4,6-trimethy-pyranylium tetrafluoroborate(TMP-TFB)-derivatized matrix-assisted laser desorption mass spectrometry(MALDI-MS)imaging of dopamine identihed elevated striataldopamine levels in mouse brains with oral Enterococcus,and BBR strengthened the imaging intensity of brain dopamine.Theseresults demonstrated that BBR was an agonist of TH in Enterococcus and could lead to the production of L-dopa in the gut.Furthermore,a study of 28 patients with hyperlipidemia conhrmed that oral BBR increased bloodfecal L-dopa by the intestinalbacteria.Hence,BBR might improve the brain function by upregulating the biosynthesis of-dopa in the gut microbiota through avitamin-like effect. | Yan Wang Qian Tong Shu-Rong Ma Zhen-Xiong Zhao Li-Bin Pan Lin Cong Pei Han Ran Peng Hang Yu Yuan Lin Tian-Le Gao Jia-Wen Shou Xiao-Yang Li Xian-Feng Zhang Zheng-Wei Zhang Jie Fu Bao-Ying Wen Jin-Bo Yu Xuetao Cao Jian-Dong Jiang | 2021 | Signal Transduction and Targeted Therapy2021，6，3： | 16 |
| 4 | Association of Overlapped and Un-overlapped Comorbidities with COVID-19 Severity and Treatment Outcomes: A Retrospective Cohort Study from Nine Provinces in China显示文摘Objective Several COVID-19 patients have overlapping comorbidities. The independent role of each component contributing to the risk of COVID-19 is unknown, and how some non-cardiometabolic comorbidities affect the risk of COVID-19 remains unclear.Methods A retrospective follow-up design was adopted. A total of 1,160 laboratory-confirmed patients were enrolled from nine provinces in China. Data on comorbidities were obtained from the patients’ medical records. Multivariable logistic regression models were used to estimate the odds ratio(OR) and 95% confidence interval(95% CI) of the associations between comorbidities(cardiometabolic or non-cardiometabolic diseases), clinical severity, and treatment outcomes of COVID-19.Results Overall, 158(13.6%) patients were diagnosed with severe illness and 32(2.7%) had unfavorable outcomes. Hypertension(2.87, 1.30–6.32), type 2 diabetes(T2 DM)(3.57, 2.32–5.49),cardiovascular disease(CVD)(3.78, 1.81–7.89), fatty liver disease(7.53, 1.96–28.96), hyperlipidemia(2.15, 1.26–3.67), other lung diseases(6.00, 3.01–11.96), and electrolyte imbalance(10.40, 3.00–26.10)were independently linked to increased odds of being severely ill. T2 DM(6.07, 2.89–12.75), CVD(8.47,6.03–11.89), and electrolyte imbalance(19.44, 11.47–32.96) were also strong predictors of unfavorable outcomes. Women with comorbidities were more likely to have severe disease on admission(5.46,3.25–9.19), while men with comorbidities were more likely to have unfavorable treatment outcomes(6.58, 1.46–29.64) within two weeks.Conclusion Besides hypertension, diabetes, and CVD, fatty liver disease, hyperlipidemia, other lung diseases, and electrolyte imbalance were independent risk factors for COVID-19 severity and poor treatment outcome. Women with comorbidities were more likely to have severe disease, while men with comorbidities were more likely to have unfavorable treatment outcomes. | MA Yan ZHU Dong Shan CHEN Ren Bo SHI Nan Nan LIU Si Hong FAN Yi Pin WU Gui Hui YANG Pu Ye BAI Jiang Feng CHEN Hong CHEN Li Ying FENG Qiao GUO Tuan Mao HOU Yong HU Gui Fen HU Xiao Mei HU Yun Hong HUANG Jin HUANG Qiu Hua HUANG Shao Zhen JI Liang JIN Hai Hao LEI Xiao LI Chun Yan LI Min Qing LI Qun Tang LI Xian Yong LIU Hong De LIU Jin Ping LIU Zhang MA Yu Ting MAO Ya MO Liu Fen NA Hui WANG Jing Wei SONG Fang Li SUN Sheng WANG Dong Ting WANG Ming Xuan WANG Xiao Yan WANG Yin Zhen WANG Yu Dong WU Wei WU Lan Ping XIAO Yan Hua XIE Hai Jun XU Hong Ming XU Shou Fang XUE Rui Xia YANG Chun YANG Kai Jun YUAN Sheng Li ZHANG Gong Qi ZHANG Jin Bo ZHANG Lin Song ZHAO Shu Sen ZHAO Wan Ying ZHENG Kai ZHOU Ying Chun ZHU Jun Teng ZHU Tian Qing ZHANG Hua Min WANG Yan Ping WANG Yong Yan 无 | 2020 | Biomedical and Environmental Sciences2020，33，12： | 8 |
| 5 | Accelerated evolution of an Lhx2 enhancer shapes mammalian social hierarchies显示文摘Social hierarchies emerged during evolution,and social rank influences behavior and health of individuals.However,the evolutionary mechanisms of social hierarchy are still unknown in amniotes.Here we developed a new method and performed a genome-wide screening for identifying regions with accelerated evolution in the ancestral lineage of placental mammals,where mammalian social hierarchies might have initially evolved.Then functional analyses were conducted for the most accelerated region designated as placental-accelerated sequence 1(PAS1,P=3.15 × 10^-18).Multiple pieces of evidence show that PAS1 is an enhancer of the transcription factor gene Lhx2 involved in brain development.PAS1s isolated from various amniotes showed different c/s-regulatory activity in vitro,and affected the expression of Lhx2 differently in the nervous system of mouse embryos.PAS1 knock-out mice lack social stratification.PAS1 knock-in mouse models demonstrate that PAS1s determine the social dominance and subordinate of adult mice,and that social ranks could even be turned over by mutated PAS1.All homozygous mutant mice had normal huddled sleeping behavior,motor coordination and strength.Therefore,PAS1-Lhx2 modulates social hierarchies and is essential for establishing social stratification in amniotes,and positive Darwinian selection on PAS1 plays pivotal roles in the occurrence of mammalian social hierarchies. | Yuting Wang Guangyi Dai Zhili Gu Guopeng Liu Ke Tang Yi-Hsuan Pan Yujie Chen Xin Lin Nan Wu Haoshan Chen Su Feng Shou Qiu Hongduo Sun Qian Li Chuan Xu Yanan Mao Yong Edward Zhang Philipp Khaitovich Yan-Ling Wang Qunxiu Liu Jing-Dong Jackie Han Zhen Shao Gang Wei Chun Xu Naihe Jing Haipeng Li | 2020 | Cell Research2020，30，5： | 4 |
| 6 | Efficacy of radiotherapy for the treatment of cystic echinococcosis in naturally infected sheep显示文摘Background:Radiotherapy is commonly used to treat cancers.To date,there has been no study focusing on the effects of radiotherapy on hydatid disease in large animals.In this study,we aim to investigate the efficiency and safety of radiotherapy for treating hydatid disease caused by Echinococcus granulosus in naturally infected sheep.Methods:Ultrasound was used to screen naturally infected sheep in an echinococcosis endemic area in Xinjiang,China.A computer tomography(CT)scan confirmed the presence of hydatid cysts.Twenty sheep naturally infected with E.granulosus in the liver and/or lungs were randomly assigned into four groups receiving no irradiation,or X-ray irradiation of low(30 Gy),medium(45 Gy),and high dose(60 Gy),respectively.After three months of radiotherapy,a CT scan was performed to measure the changes in the cysts.The hepatic parasite cysts and host tissues were collected for histology and gene expression analysis.Results:In the animals subject to irradiation,no significant differences were observed in their appetite,daily activities,and weight before and after radiotherapy.Severe calcification was noticed in the cysts subject to a high dose of radiation compared with the groups subject to low and medium doses.Hematoxylin and eosin staining showed that irradiation contributed to the damage of the cyst structure and nucleus in the germinal layers.Quantitative PCR demonstrated that expression of TPX and HSP70 significantly decreased in a dose-dependent manner(P<0.05).The expression of the EPC1 decreased in the medium-and high-dose groups compared with the low-dose group(P<0.05).Meanwhile,the expression of radiation-related apoptosis genes caspase-3 and Gadd45 decreased with an increase in the irradiation dose.Conclusions:Radiotherapy is an option with satisfactory efficiency and safety for treating cystic echinococcosis in sheep with partial response or stable disease at month 3.In future,inhibition of cystic activity using radiotherapy may serve as a new regimen for treating hydatid disease. | Rui Mao Wen-Bao Zhang Hong-Zhi Qi Tao Jiang Ge Wu Peng-Fei Lu Abudula Ainiwaer Ge Shang Lin Xu Jie Hao Xi Shou Hai-Tao Li Jun Li Song-An Zhang Yong-Xing Bao Hao Wen | 2017 | Infectious Diseases of Poverty2017，6，1： | 4 |

| 8 | The density matrix picture of laser coherent control current显示文摘The physical substance of the coherent control current and the optical rectification have been analyzed based on density matrix perturbation theory. The analytical results demonstrate that they arise from the real and virtual manifestations of the same nonlinear process associated with diagonal and non-diagonal density matrix. And in terms of polarization, they respectively arise from the intraband and interband polarizations. Both the evolution of the coherent control current exited by ultrafast laser pulse and its dependence on frequency have been studied in time and frequency domains. In order to get an explicit knowledge of intraband polarization and the origination of the coherent control current, we have investigated the initial photo-carriers momentum distribution. The ultrafast decay of the polar momentum population in order of tens of femtosends is given to illustrate its instantaneous optical response. | SHOU Qian ZHANG Haichao LIU Luning LIN Weizhu | 2004 | Science China(Physics,Mechanics & Astronomy)2004，47，2： | 3 |
| 9 | Panda X-III: Searching for neutrinoless double beta decay with high pressure ^(136)Xe gas time projection chambers显示文摘Searching for the neutrinoless double beta decay(NLDBD)is now regarded as the topmost promising technique to explore the nature of neutrinos after the discovery of neutrino masses in oscillation experiments.Panda X-III(particle and astrophysical xenon experiment III)will search for the NLDBD of136Xe at the China Jin Ping Underground Laboratory(CJPL).In the first phase of the experiment,a high pressure gas Time Projection Chamber(TPC)will contain 200 kg,90%136Xe enriched gas operated at10 bar.Fine pitch micro-pattern gas detector(Microbulk Micromegas)will be used at both ends of the TPC for the charge readout with a cathode in the middle.Charge signals can be used to reconstruct the electron tracks of the NLDBD events and provide good energy and spatial resolution.The detector will be immersed in a large water tank to ensure~5 m of water shielding in all directions.The second phase,a ton-scale experiment,will consist of five TPCs in the same water tank,with improved energy resolution and better control over backgrounds. | Xun Chen Chang Bo Fu Javier Galan Karl Giboni Franco Giuliani Ling Hui Gu Ke Han Xiang Dong Ji Heng Lin Jiang Lai Liu Kai Xiang Ni Hiroki Kusano Xiang Xiang Ren Shao Bo Wang Yong Yang Dan Zhang Tao Zhang Li Zhao Xiang Ming Sun Shou Yang Hu Si Yu Jian Xing Long Li Xiao Mei Li Hao Liang Huan Qiao Zhang Ming Rui Zhao Jing Zhou Ya Jun Mao Hao Qiao Si Guang Wang Ying Yuan Meng Wang Amir N.Khan Neill Raper Jian Tang Wei Wang Jia Ning Dong Chang Qing Feng Cheng Li Jian Bei Liu Shu Bin Liu Xiao Lian Wang Dan Yang Zhu Juan F.Castel Susana Cebri'an Theopisti Dafni Javier G.Garza Igor G.Irastorza Francisco J.Iguaz Gloria Luz ′on Hector Mirallas Stephan Aune Eric Berthoumieux Yann Bedfer Denis Calvet Nicole d'Hose Alain Delbart Maria Diakaki Esther Ferrer-Ribas Andrea Ferrero Fabienne Kunne Damien Neyret Thomas Papaevangelou Franck Sabatie Maxence Vanderbroucke AnDi Tan Wick Haxton Yuan Mei Chinorat Kobdaj Yu-Peng Yan | 2017 | Science China(Physics,Mechanics & Astronomy)2017，60，6： | 2 |
| 10 | Application of fluorescence in situ hybridization in the detection of bladder transitional-cell carcinoma: A multi-center clinical study based on Chinese population显示文摘Objective:To evaluate the diagnostic value of fluorescence in situ hybridization(FISH)in bladder cancer.Methods:We enrolled healthy volunteers and patients who were clinically suspected to have bladder cancer and conducted FISH tests and cytology examinations from August 2007 to December 2008.Receiver operating characteristic(ROC)curve analysis was performed and the area under curve(AUC)values were calculated for both the FISH and urine cytology tests.Results:A cohort of 988 healthy volunteers was enrolled to establish a reference range for the normal population.A total of 4807 patients with hematuria were prospectively,randomly enrolled for the simultaneous analysis of urine cytology,FISH testing,and a final diagnosis as determined by the pathologic findings of a biopsy or a surgically-excised specimen.Overall,the sensitivity of FISH in detecting transitional-cell carcinoma was 82.7%,while that of cytology was 33.4%(p<0.001).The sensitivity values of FISH for non-muscle invasive and muscle invasive bladder transitional-cell carcinoma were 81.7%and 89.6%,respectively(p=0.004).The sensitivity values of FISH for low and high grade bladder cancer were 82.6%and 90.1%,respectively(p=0.002).Conclusion:FISH is significantly more sensitive than voided urine cytology for detecting bladder cancer in patients evaluated for gross hematuria at all cancer grades and stages.Higher sensitivity using FISH was obtained in high grade and muscle invasive tumors. | Liqun Zhou Kaiwei Yang Xuesong Li Yi Ding Dawei Mu Hanzhong Li Yong Yan Jinyi Li Dongwen Wang Wei Li Yulong Cong Jiangping Gao Kewei Ma Yajun Xiao Sheng Zhang Hongyi Jiang Weilie Hu Qiang Wei Xunbo Jin Zhichen Guan Qingyong Liu Danfeng Xu Xin Gao Yongguang Jiang Weimin Gan Guang Sun Qing Wang Yanhui Liu Jianquan Hou Liping Xie Xishuang Song Fengshuo Jin Jiafu Feng Ming Cai Zhaozhao Liang Jie Zhang Dingwei Ye Lin Qi Lulin Ma Jianzhong Shou Yuping Dai Jianyong Shao Ye Tian Shizhe Hong Tao Xu Chuize Kong Zefeng Kang Yuexin Liu Xun Qu Benkang Shi Shaobin Zheng Yi Lin Shujie Xia Dong Wei Jianbo Wu Weiling Fu Zhiping Wang Jianbo Liang | 2019 | Asian Journal of Urology2019，6，1： | 2 |

| 13 | Real-world outcomes of niraparib treatment in patients with ovarian cancer:amulticenter non-interventional study in China显示文摘Dear Editor,Ovarian cancer remains the deadliest among all gynecological cancers.Although most patients at advanced stage respond to initial treatment,the majority experience recurrence[1].It was estimated that 55,342 new cases and 37,519 deaths from ovarian cancer occurred in China annually[2].Contemporarily,the treatment landscape has changed rapidly since the role of poly(adenosine diphosphate-ribose)polymerase inhibitors(PARPi)in ovarian cancer treatmentwas explored.Based on data from the PRIMA/ENGOT-OV26/GOG-3012[3]and ENGOTOV16/NOVA trials[4],niraparib has been approved globally as maintenance therapy for newly diagnosed and platinum-sensitive recurrent ovarian cancer.The indication of niraparib for salvage treatment was based on the results of the QUADRA(NCT02354586)trial[5].Although niraparib has been tested in prospective randomized clinical trials(RCTs),no multicenter study on its real-world application in China had been conducted.Considering the differences in population,accessibility and affordability of drugs,the results of the real-world settings may differ from those of RCTs.Therefore,we conducted this multicenter,non-interventional study at 8 hospitals. | Jin Li Jianhua Yang Huafeng Shou Lin Zhang Xiaohong Huang Xuedong Tang Fei Zheng Fang Liu Hao Wen Huijuan Yang Huaying Wang Ziting Li Xiaojun Chen Xingzhu Ju Xi Cheng Jie Tang Meiqin Zhang Xiaohua Wu | 2023 | Cancer Communications2023，43，6： | 0 |
| 14 | Epipelagic mesozooplankton communities in the northeastern Indian Ocean off Myanmar during the winter monsoon显示文摘The northern Andaman Sea off Myanmar is one of the relatively high productive regions in the Indian Ocean.The abundance,biomass and species composition of mesozooplankton and their relationships with environmental variables in the epipelagic zone(~200 m)were studied for the first time during the Sino-Myanmar joint cruise(February 2020).The mean abundance and biomass of mesozooplankton were(1916.7±1192.9)ind./m3and(17.8±7.9)mg/m3,respectively.A total of 213 species(taxa)were identified from all samples.The omnivorous Cyclopoida Oncaea venusta and Oithona spp.were the top two dominant taxa.Three mesozooplankton communities were determined via cluster analysis:the open ocean in the Andaman Sea and the Bay of Bengal(Group A),the transition zone across the Preparis Channel(Group B),and nearshore water off the Ayeyarwady Delta and along the Tanintharyi Coast(Group C).Variation partitioning analysis revealed that the interaction of physical and biological factors explained 98.8%of mesozooplankton community spatial variation,and redundancy analysis revealed that column mean chlorophyll a concentration(CMCHLA)was the most important explanatory variable(43.1%).The abundance and biomass were significantly higher in Group C,the same as CMCHLA and column mean temperature(CMT)and in contrast to salinity,and CMT was the dominant factor.Significant taxon spatial variations were controlled by CMCHLA,salinity and temperature.This study suggested that mesozooplankton spatial variation was mainly regulated by physical processes through their effects on CMCHLA.The physical processes were simultaneously affected by heat loss differences,freshwater influx,eddies and depth. | Ping Du Dingyong Zeng Feilong Lin Sanda Naing Zhibing Jiang Jingjing Zhang Di Tian Qinghe Liu Yuanli Zhu Soe Moe Lwin Wenqi Ye Chenggang Liu Lu Shou Feng Zhou | 2023 | Acta Oceanologica Sinica2023，42，6： | 0 |
| 15 | Primary gastrointestinal stromal tumor of the liver treated with sequential therapy显示文摘A 67-year-old female presented with a primary hepatic gastrointestinal stromal tumor that was detected by computed tomography and diagnosed based on histopathological and genetic analyses.The tumor was microscopically composed of spindle cells and epithelioid cells,and immunohistochemistry results showed positive staining for CD117 and CD34expression.A genetic analysis revealed a heterozygous point mutation and deletion in exon 11 of c-KIT.After an R0 resection,imatinib mesylate was administered for 1 year until its use was discontinued due to severe side effects.Two years after the original operation,the tumor recurred in the residual liver and was completely resected again.Imatinib mesylate was administered for 2 years until it was replaced by sunitinib malate because of disease progression.The patient has survived for 53 mo after undergoing a sequential therapy consisting of surgical excision,imatinib and sunitinib. | Xian-Ke Lin Qing Zhang Wei-Li Yang Chun-Hui Shou Xiao-Sun Liu Jian-Yi Sun Ji-Ren Yu | 2015 | World Journal of Gastroenterology2015，21，8： | 0 |
