| 1 | 2018 Chinese Pediatric Cardiology Society(CPCS) guideline for diagnosis and treatment of syncope in children and adolescents显示文摘Syncope belongs to the transient loss of consciousness(TLOC), characterized by a rapid onset, short duration, and spontaneous complete recovery. It is common in children and adolescents, accounting for 1% to 2% of emergency department visits.Recurrent syncope can seriously affect children's physical and mental health, learning ability and quality of life and sometimes cardiac syncope even poses a risk of sudden death. The present guideline for the diagnosis and treatment of syncope in children and adolescents was developed for guiding a better clinical management of pediatric syncope. Based on the globally recent development and the evidence-based data in China, 2018 Chinese Pediatric Cardiology Society(CPCS) guideline for diagnosis and treatment of syncope in children and adolescents was jointly prepared by the Pediatric Cardiology Society, Chinese Pediatric Society, Chinese Medical Association(CMA)/Committee on Pediatric Syncope, Pediatricians Branch, Chinese Medical Doctor Association(CMDA)/Committee on Pediatric Cardiology, Chinese College of Cardiovascular Physicians, Chinese Medical Doctor Association(CMDA)/Pediatric Cardiology Society, Beijing Pediatric Society, Beijing Medical Association(BMA). The present guideline includes the underlying diseases of syncope in children and adolescents, the diagnostic procedures, methodology and clinical significance of standing test and headup tilt test, the clinical diagnosis vasovagal syncope, postural orthostatic tachycardia syndrome, orthostatic hypotension and orthostatic hypertension, and the treatment of syncope as well as follow-up. | Cheng Wang Yaqi Li Ying Liao Hong Tian Min Huang Xiangyu Dong Lin Shi Jinghui Sun Hongfang Jin Junbao Du Jindou An Jie Chen Mingwu Chen Qi Chen Sun Chen Yonghong Chen Zhi Chen Adolphus Kai-tung Chau Junbao Du Zhongdong Du Junkai Duan Hongyu Duan Xiangyu Dong Lin Feng Lijun Fu Fangqi Gong Yonghao Gui Ling Han Zhenhui Han Bing He Zhixu He Xiufen Hu Yimin Hua Guoying Huang Min Huang Ping Huang Yujuan Huang Hongfang Jin Mei Jin Bo Li Fen Li Tao Li Xiaohui Li Xiaoyan Liu Yan Li Haitao Lv Tiewei Lv Zipu Li Luyi Ma Silin Pan Yusheng Pang Hua Peng Yuming Qin Jie Shen Lin Shi Kun Sun Jinghui Sun Hong Tian Jie Tian Cheng Wang Hong Wang Lei Wang Jinju Wang Wendi Wang Yuli Wang Rongzhou Wu Tianhe Xia Yanyan Xiao Chunhong Xie Yanlin Xing Zhenyu Xiong Baoyuan Xu Yi Xu Hui Yan Shiwei Yang Qijian Yi Xia Yu Xianyi Yu Yue Yuan Hongyan Zhang Huili Zhang Li Zhang Qingyou Zhang Xi Zhang Yanmin Zhang Zhiwei Zhang Cuifen Zhao Bin Zhou Hua Zhu | 2018 | Science Bulletin2018，63，23： | 54 |
| 2 | Level of circulating PD-L1 expression in patients with advanced gastric cancer and its clinical implications显示文摘Objective:The programmed cell death-1 receptor/programmed cell death-1 ligand(PD-1/PD-L1) pathway plays a crucial role in tumor evasion from host immunity.This study was designed to evaluate the association between circulating PD-L1 expression and prognosis in patients with advanced gastric cancer.Methods:Totally 80 advanced gastric cancer patients and 40 health controls from Beijing Cancer Hospital were enrolled in the present study.Circulating PD-L1 expression was tested by enzymelinked immunosorbent assay(ELISA).The associations between the expression level of PD-L1 and clinicopathological features and prognosis were analyzed statistically.Results:Expression of PD-L1 in advanced gastric cancer patients was significantly up-regulated compared with health people(P=0.006).The expression of PD-L1 was significantly correlated with differentiation and lymph node metastasis(P=0.026 and P=0.041,respectively).Although we didn't find significant difference in all advanced gastric cancer patients with different PD-L1 expression,the adenocarcinoma patients with higher up-regulated PD-L1 expression had much better prognosis than low expression patients(65.6% vs.44.7%,P=0.028).Conclusions:PD-L1 was elevated in advance gastric cancer patients and may play an important role in tumor immune evasion and patients prognosis. | Zhixue Zheng Zhaode Bu Xijuan Liu Lianhai Zhang Ziyu Li Aiwen Wu Xiaojiang Wu Xiaojing Cheng Xiaofang Xing Hong Du Xiaohong Wang Ying Hu Jiafu Ji | 2014 | Chinese Journal of Cancer Research2014，26，1： | 37 |
| 3 | Prevalence and evolution of drug resistance HIV-1 variants in Henan, China显示文摘To understand the prevalence and evolution of drug resistant HIV strains in Henan China after the implementation of free antiretroviral therapy for AIDS patients. 45 drug nave AIDS patients, 118 AIDS patients who received three months antiretroviral therapy and 124 AIDS patients who received six months antiretroviral treatment were recruited in the southern part of Henan province. Information on general condition, antiretroviral medicines, adherence and clinical syndromes were collected by face to face interview. Meanwhile, 14ml EDTA anticoagulant blood was drawn. CD4/CD8 T cell count, viral load and genotypic drug resistance were tested. The rates of clinical improvement were 55.1% and 50.8% respectively three months and six months after antiretroviral therapy. The mean CD4 cell count after antiretroviral therapy was significantly higher than in drug nave patients. The prevalence rate of drug resistant HIV strains were 13. 9%, 45.4% and 62.7% in drug nave patients, three month treatment patients and six month treatment patients, respectively. The number of resistance mutation codons and the frequency of mutations increased significantly with continued antiretroviral therapy. The mutation sites were primarily at the 103, 106 and 215 codons in the three-month treatment group and they increased to 15 codon mutations in the six-month treatment group. From this result, the evolution of drug resistant strains was inferred to begin with the high level NNRTI resistant strain, and then develop low level resistant strains to NRTIs. The HIV strains with high level resistance to NVP and low level resistance to AZT and DDI were highly prevalent because of the AZT+DDI+NVP combination therapy. These HIV strains were also cross resistant to DLV, EFV, DDC and D4T. Poor adherence to therapy was believed to be the main reason for the emergence and prevalence of drug resistant HIV strains. The prevalence of drug resistant HIV strains was increased with the continu- ation of antiretroviral therapy in the southern part of Henan province. Measures, that could promote high level adherence, provide new drugs and change ART regimens in failing patients, should be implemented as soon as possible. | Jing Yun LI Han Ping LI Lin LI Hong LI Zhe WANG Kun YANG Zuo Yi BAO Dao Min ZHUANG Si Yang LIU Yong Jian LIU Hui XING Yi Ming SHAO | 2005 | Cell Research2005，15，11： | 34 |

| 5 | Induction of apoptosis of human gastric carcinoma SGC-7901 cell line by 5,7-dihydroxy-8-nitrochrysin in vitro显示文摘AIM: To investigate the effect of 5, 7-dihydroxy-8- nitrochrysin (NOChR) on apoptosis of human gastric carcinoma SGC-7901 cell line. METHODS: SGC-7901 cells were cultured in vitro and the inhibitory effect of NOChR on proliferation of SGC-7901 cells was measured by using an MTT assay. NOChR-induced apoptosis rate of SGC-7901 cells was detected using flow cytometry (FCM) with PI staining. DNA ladder bands were observed by DNA agarose gel electrophoresis. The influence of NOChR on the proxisome proliferator-activated receptor-γ (PPARγ), Bcl-2 and Bax protein expression of SGC-7901 cells was analyzed by Western blot. RESULTS: MTT assay showed that NOChR markedly inhibited proliferation of SGC-7901 cells in a dose- dependent manner, and when IC50 was 4.14 μmol/L, the potency of NOChR was 10 times than that of lead compound, chrysin (ChR, IC50 was 40.56 μmol/L), and was similar to 5-fluorouracil (5-FU, IC50 was 4.51 μmol/L). FCM with propidium iodide (PI) staining demonstrated that the apoptosis rates of SGC-7901 cells treated with 1.25, 5.00 and 20.00 μmol/L NOChR for 48 h were 9.8% ± 0.2%, 36.8% ± 1.9% and 45.5% ± 3.5%, respectively, and were significantly higher when treated with 5.00 and 20.00 μmol/L NOChR than that with 20.00 μmol/L ChR (12.9% ± 1.5%). DNA agarose gel electrophoresis showed that treatment of SGC-7901 cells with 20.00 μmol/L NOChR for 48 h resulted in typical DNA ladder bands of DNA of SGC-7901 cells, which could be eliminated by treating with 10.00 μmol/L GW9662, a blocker of PPARγ. Western blot analysis revealed that after 24 h of treatment with 20.00 μmol/L NOChR, PPARgamma and Bax protein expression of SGC-7901 cells increased but Bcl-2 expression decreased; however, pre-incubation with 10.00 μmol/L GW9662 could efficiently antagonize and weaken the regulatory effect of 20.00 μmol/L NOChR on Bax and Bcl-2 protein expression of SGC-7901 cells. CONCLUSION: NOChR induces apoptosis of SGC-7901 cell lines by activating PPARγ and decreasing ratio of Bcl-2 to Bax. | Xiao-Hong Ai Xing Zheng Xiao-Qing Tang Li Sun Yang-Qin Zhang Yong Qin Hua-Qing Liu Hong Xia Jian-Guo Cao | 2007 | World Journal of Gastroenterology2007，13，28： | 22 |

Effect of S-ODNson SMMC-7721 human hepatoma cell growth invitro was determined using microculturetetrazolium assay. In vivo antitumor activitiesof S-ODNs were monitored by measuring tumorweight differences in treated and control micebearing SMMC-7721 xenografts. Induction of cellapoptosis was evaluated by fluorescence-activated cell sorter (FACS) analysis.RESULTS Antisense S-ODN treatment led toreduced AFP gene expression. Specificantisense S-ODNs, but not control S-ODNs,inhibited the growth of heaptoma cells in vitro.In vivo. only antisense S-ODNs exhibitedobvious antitumor activities. FACS analysisrevealed that the growth inhibition by antisenseS. ODNs was associated with their cell apoptosisinduction.CONCLUSION Antisense S-ODNs targeted toAFP genes inhibit the growth of human hepatomacells and solid hepatoma, which is related totheir cell apoptosis induction. | Xing Wang Wang~1 Jin Hui Yuan~1 Ru Gang Zhang~1 Li Xia Guo~1 Yong Xie~2 Hong Xie~1 ~1Department of Biotherapy,Shanghai Institute of Cell Biology,Chinese Academy of Sciences,Shanghai 200031,China ~2Department of Biology,Hong Kong University of Science and Technology,ChinaDr.Xing Wang Wang earned Ph.D.from Shanghai Institute of Materia Medical,Chinese Academy of Sciences in 1997.Now a professor at Shanghai Institute of Cell Biology,Chinese Academy of Sciences. | 2001 | World Journal of Gastroenterology2001，7，3： | 21 |
| 8 | Growth-inhibiting effects of taxol on human liver cancer in vitro and in nude mice显示文摘AIM To investigate the effects of taxol onSMMC-7721 human hepatoma and itsmechanisms.METHODS In vitro cell growth was assessedby trypan blue exclusion method.Experimentalhepatoma model was established by seedingSMMC-7721 cells subcutaneously into Balb/c(nu/nu)nude mice.In vivo tumor growth wasdetermined by measurement of tumor diameterwith Vernier calipers.The syntheses of DNA,RNA and protein were analyzed by incorporationof ~3H-thymidine,~3H-uridine and ~3H-leucinerespectively.Using light and electronmicroscopes to observe the morphologicalchanges of cells including mitosis andapoptosis.RESULTS Taxol was effective against SMMC-7721 human hepatoma cell growth in the rangesof 2.5 nmol/L-10 nmol/L with mitotic arrestand apoptosis in vitro.DNA,RNA and proteinsyntheses in cells were also obviouslysuppressed by in vitro treatment of taxol for72 h.Taxol at 2.5 nmol/L reduced ~3H-thymidineuptake to about 34% of the control value(P<0.05).Increasing the dose of taxol to20 nmol/L resulted in a greater decrease in ~3H-thymidine incorporation to 60% of the controlvalue(P<0.01).At a concentration of 20 nmol/L,the ~3H-uridine and ~3H-leucine uptakeswere reduced to 52%(P<0.05)and 63%(P<0.01),respectively.In vivo,taxolsignificantly inhibited SMMC-7721 tumor growthat 10 mg/kg,i.p.,once daily for 10 d.A morethan 90% decrease in tumor volume wasobserved by day 11(P<0.01)similarly withmitotic arrest and cell apoptosis.CONCLUSION Taxol has a marked anticanceractivity in SMMC-7721 human hepatoma both invitro and in nude mice.Its mechanisms might beassociated with mitotic arrest,subsequently,apoptosis of the hepatoma cells.No obvioustoxicity was observed with in vivoadministration of taxoi. | Jin Hui Yuan Ru Ping Zhang Ru Gang Zhang Li Xia Guo Xing Wang Wang Dan Luo Yong Xie Hong Xie | 2000 | World Journal of Gastroenterology2000，6，2： | 18 |
| 9 | LGR5 is a promising biomarker for patients with stage Ⅰ and Ⅱ gastric cancer显示文摘Objective: To investigate Leucine-rich repeat-containing G protein-coupled receptor 5 (LGR5) expressions in gastric cancer and to evaluate its clinical significance. Methods: LGR5 expression was assessed by immunohistochemistry in 257 gastric cancer patients after surgery. The relationships between LGR5 expression and clinicopathological features and patients prognosis were statistically analyzed. Results: The expression of LGR5 was significantly higher in gastric cancers as a cancer stem cell marker than in adjacent normal tissues (P<0.001), and more frequently in patients with intestinal type, well-moderate differentiation and stage Ⅰ and Ⅱ (P<0.05). Although we found gastric cancer patients with LGR5 positive expression had a poorer prognosis, it didn't meet statistical significance (P>0.05). LGR5 negative expression was significantly related to the favorable overall survival in stage Ⅰ and Ⅱ gastric cancer patients (P<0.05). Furthermore, patients with high LGR5 expression tended to be more likely to get progression and have poorer progress-free survival (P<0.05). Multivariate Cox regression analysis revealed that LGR5 expression was an independent factor of overall survival for the patients with stage Ⅰ and Ⅱ gastric cancer (P<0.05). Conclusions: Our results show that LGR5 may play an important role in tumorigenesis and progression and would be a powerful marker to predict the prognosis of patients with stage Ⅰ and Ⅱ gastric cancer. | Zhaode Bu Zhixue Zheng Lianhai Zhang Ziyu Li Yu Sun Bin Dong Aiwen Wu Xiaojiang Wu Xiaohong Wang Xiaojing Cheng Xiaofang Xing Yingai Li Hong Du Jiafu Ji | 2013 | Chinese Journal of Cancer Research2013，25，1： | 17 |
| 10 | Increase of TNFα-stimulated Osteoarthritic Chondrocytes Apoptosis and Decrease of Matrix Metalloproteinases 9 by NF-κB Inhibition显示文摘Objective To investigate the in vitro effect of caffeic acid phenethyl ester(CAPE),a NF-κB inhibitor,on the apoptosis of osteoarthritic(OA)chondrocytes and on the regulation of the gelatinases matrix metalloproteinase 2(MMP-2)and matrix metalloproteinase 9(MMP-9).Methods Annexin V-FITC/propidium iodide(PI)labeling and western blotting were used to observe and determine the apoptosis in TNFα-stimulated primary cultured osteoarthritic chondrocytes.Also,gelatin zymography was applied to examine MMP-2 and MMP-9 activities in supernatants.Results It was confirmed by both flow cytometry and western blotting that chondrocytes from OA patients have an apoptotic background.Use of CAPE in combination with 10 ng/mL of TNFα for 24 h facilitated the apoptosis.MMP-9 in the supernatant could be autoactivated(from proMMP-9 to active MMP-9),and the physiologic calcium concentration(2.5 mmol/L)could delay the autoactivation of MMP-9.The activities of MMP-2 and MMP-9 in the fresh supernatant increased significantly in response to stimulation by 10 ng/mL of TNFα for 24 h.The stimulatory effect of TNFα just on proMMP-9 was counteracted significantly by CAPE.Conclusion NF-κB could prevent chondrocytes apoptosis though its activation was attributed to the increase of proMMP-9 activity induced by TNFα(a pro-apoptotic factor).Therefore,therapeutic NF-κB inhibitor was a 'double-edged swords' to the apoptosis of chondrocytes and the secretion of MMP-9. | WANG Yan LI De Ling ZHANG Xin Bo DUAN Yuan Hui WU Zhi Hong HAO Dong Sheng CHEN Bao Sheng QIU Gui Xing | 2013 | Biomedical and Environmental Sciences2013，26，4： | 13 |

| 14 | Promoting ring-opening efficiency for suppressing toxic intermediates during photocatalytic toluene degradation via surface oxygen vacancies显示文摘Aromatic ring-opening process is well recognized as the rate-determining step for catalytic toluene degradation. In photocatalytic toluene degradation, the toxic intermediates w让h harmful effects may be generated. To clarify the precise reaction mechanism and control the toxic intermediates generation, a closely combined in situ DRIFTS and DFT calculation is utilized to address these important issues. We construct the BiOCl w让h oxygen vacancies (OVs) and reveal the structure of OVs. The defect level caused by oxygen vacancies could promote the light adsorption and charge separation, which further boosts the activation of ring-opening species and enhances the generation process of free radicals. The reaction energy barriers of four possible ring-opening processes on defective BiOCl (OVBOC) are all declined in comparison with perfect BiOCl (BOC). The existence of oxygen vacancies could smooth the ratedetermining step so the ring-opening efficiency of photocatalytic toluene degradation is highly increased. Most importantly, the methyl species would be further oxidized and tend to open the benzene-ring at benzoic acid on BOC while the ring would be broken at the benzyl alcohol on OVBOC. These results indicate that the toluene degradation pathway is shortened via the surface OVs, which enables the production of radicals with high oxidation capability for the accelerated chain scission of the ring-opening intermediates. Finally, the efficiency of the key ring-opening process could be enormously improved and toxic intermediates are effectively restrained. The present work could provide new insights into the design of high-performance photocatalysts for efficient and safe degradation of VOCs in air. | Xing'an Dong Wen Cui Hong Wang Jieyuan Li Yanjuan Sun Haiqiang Wang Yuxin Zhang Hongwei Huang Fan Dong | 2019 | Science Bulletin2019，64，10： | 9 |
| 15 | Effects of targeting magnetic drug nanoparticles on human cholangiocarcinoma xenografts in nude mice显示文摘BACKGROUND:Targeting is a new therapeutic tool for malignant tumor as a result of combining nanotechnology with chemotherapeutics.The aim of our study was to investigate the effects of magnetic nanoparticles enveloping a chemotherapeutic drug on human cholangiocarcinoma xenografts in nude mice. METHODS:The human cholangiocarcinoma xenograft model was established in nude mice with the QBC939 cell line.The nude mice were randomly assigned to 7 groups. 0.9%saline or magnetic nanoparticles,including high (group 2),medium(group 4)and low(group 5)dosages, were given to nude mice through the tail vein 20 days after the QBC939 cell line was implanted.Calculations were made 35 days after treatment in order to compare the volumes,inhibition ratios and growth curves of the tumors in each group.Mice in each group were sacrificed randomly to collect tumor tissues and other organs for electron microscopy and pathological examination. RESULTS:The high and medium dosage groups were significantly different from the control group(P<0.05). The tumor inhibition ratios for the high,medium and low dosage groups were 39.6%,14.6%and 7.9%,respectively. The tumor growth curve of groups 5,4,and 2 changed slowly in turn.The high and medium groups showed cell apoptosis under an electron microscope.CONCLUSION:Magnetic nanoparticles can inhibit the growth of human cholangiocarcinoma xenografts in nude mice. | Tang, Tao Zheng, Jian-Wei Chen, Bo Li, Hong Li, Xi Xue, Ke-Ying Ai, Xing Zou, Sheng-Quan | 2007 | Hepatobiliary & Pancreatic Diseases International2007，6，3： | 8 |

| 18 | Identification of biomarkers for hepatocellular carcinoma by semiquantitative immunocytochemistry显示文摘AIM:To investigate the expression of key biomarkers in hepatoma cell lines,tumor cells from patients’blood samples,and tumor tissues.METHODS:We performed the biomarker tests in two steps.First,cells plated on coverslips were used to assess biomarkers,and fluorescence intensities were calculated using the NIH Image J software.The measured values were analyzed using the SPSS19.0 software to make comparisons among eight cell lines.Second,eighty-four individual samples were used to assess the biomarkers’expression.Negative enrichment of the blood samples was performed,and karyocytes were isolated and dropped onto pretreated glass slides for further analysis by immunofluorescence staining.Fluorescence intensities were compared among hepatocellular carcinoma(HCC)patients,chronic HBV-infected patients,and healthy controls following methods similar to those used for cell lines.The relationships between the expression of biomarkers and clinical pathological parameters were analyzed by Spearman rank correlation tests.In addition,we studied the distinct biomarkers’expression with three-dimensional laser confocal microscopy reconstructions,and Kaplan-Meier survival analysis was performed to understand the clinical significance of these biomarkers.RESULTS:Microscopic examination and fluorescence intensity calculations indicated that cytokeratin 8/18/19(CK)expression was significantly higher in six of the seven HCC cell lines examined than in the control cells,and the expression levels of asialoglycoprotein receptor(ASGPR)and glypican-3(GPC3)were higher in all seven HCC cell lines than in the control.Cells obtained from HCC patients’blood samples also displayed significantly higher expression levels of ASGPR,GPC3,and CK than cells from chronic HBV-infected patients or healthy controls;these proteins may be valuable surface biomarkers for identifying HCC circulating tumor cells isolated and enriched from the blood samples.The stem cell-like and epithelial-mesenchymal transition-related biomarkers could be detected on the karyocyte slides.ASGPR and GPC3 were expressed at high levels,and thus three-dimensional reconstructions were used to observe their expression in detail.This analysis indicated that GPC3 was localized in the cytoplasm and membrane,but that ASGPR had a polar localization.Survival analyses showed that expression of GPC3 and ASGPR is associated with a patient’s overall survival(OS).CONCLUSION:ASGPR,GPC3,and CK may be valuable HCC biomarkers for CTC detection;the expression of ASGPR and GPC3 might be helpful for understanding patients’OS. | Hong Mu Kai-Xuan Lin Hong Zhao Shu Xing Cong Li Fang Liu Hai-Zhen Lu Ze Zhang Yu-Lin Sun Xi-Yun Yan Jian-Qiang Cai Xiao-Hang Zhao | 2014 | World Journal of Gastroenterology2014，20，19： | 8 |

| 20 | Application of Avaatech X-ray fluorescence core-scanning in Sr/Ca analysis of speleothems显示文摘Application of X-ray fluorescence core-scanning(XRF-CS) on both marine and lake sediments has achieved remarkable results. However, its application has not been widely extended to the research on speleothems. In this study, we measure the Sr abundance and the Sr/Ca ratios of three stalagmites(two aragonite stalagmites, one calcite stalagmite) using the state-of-the-art fourth-generation Avaatech high-resolution XRF core scanner. Through comparisons among different scan paths and among different scan resolutions, as well as comparisons with inductively coupled plasma optical emission spectrometer(ICP-OES), Itrax XRF, and Artax XRF results, we confirm that the Avaatech XRF core scanner could precisely, quickly, and nondestructively analyze the high-resolution Sr abundance of speleothems. Furthermore, we combine the stalagmite δ^(18)O records to explore the paleoclimatic significance of the measured stalagmite Sr/Ca. | Dong LI Liangcheng TAN Fei GUO Yanjun CAI Youbin SUN Gang XUE Xing CHENG Hong YAN Hai CHENG R.Lawrence EDWARDS Yongli GAO Jessica KELLEY | 2019 | Science China Earth Sciences2019，62，6： | 7 |
