| 1 | Usefulness of human epididymis protein 4 in predicting cytoreductive surgical outcomes for advanced ovarian tubal and peritoneal carcinoma显示文摘Objective: Human epididymis protein 4(HE4) is a promising biomarker of epithelial ovarian cancer(EOC). But its role in assessing the primary optimal debulking(OD) of EOC remains unknown. The purpose of this study is to elucidate the ability of preoperative HE4 in predicting the primary cytoreductive outcomes in advanced EOC, tubal or peritoneal carcinoma.Methods: We reviewed the records of 90 patients with advanced ovarian, tubal or peritoneal carcinoma who underwent primary cytoreduction at the Department of Obstetrics and Gynecology of Peking University People's Hospital between November 2005 and October 2010. Preoperative serum HE4 and CA125 levels were detected with EIA kit. A receiver operating characteristic(ROC) curve was used to determine the most useful HE4 cut-off value. Logistic regression analysis was performed to identify significant preoperative clinical characteristics to predict optimal primary cytoreduction.Results: OD was achieved in 47.7%(43/48) of patients. The median preoperative HE4 level for patients with OD vs. suboptimal debulking was 423 and 820 pmol/L, respectively(P<0.001). The areas under the ROC curve for HE4 and CA125 were 0.716 and 0.599, respectively(P=0.080). The most useful HE4 cut-off value was 473 pmol/L. Suboptimal cytoreduction was obtained in 66.7%(38/57) of cases with HE4 ≥473 pmol/L compared with only 27.3%(9/33) of cases with HE4 <473 pmol/L. At this threshold, the sensitivity, specificity, positive predictive value(PPV) and negative predictive value(NPV) for diagnosing suboptimal debulking were 81%, 56%, 67%, and 73%, respectively. Logistic regression analysis showed that the patients with HE4 ≥473 pmol/L were less likely to achieve OD(odds ratio =5.044, P=0.002).Conclusions: Preoperative serum HE4 may be helpful to predict whether optimal cytoreductive surgery could be obtained or whether extended cytoreduction would be needed by an interdisciplinary team. | Zhijian Tang Xiaohong Chang Xue Ye Yi Li Hongyan Cheng Heng Cui | 2015 | Chinese Journal of Cancer Research2015，27，3： | 10 |
| 2 | IGHG1 promotes motility likely through epithelial-mesenchymal transition in ovarian cancer显示文摘Objective: Ovarian cancer(OC) is one of the leading causes of death for female cancer patients. COC166-9 is an OC-specific monoclonal antibody and we have identified immunoglobulin γ-1 heavy chain constant region(IGHG1) as its antigen. We explore the function of IGHG1 in proliferation, apoptosis and motility of OC cells further in this research.Methods: IGHG1 expression in OC specimens was detected through immunohistochemistry. Real-time quantitative polymerase chain reaction(RT-q PCR) or western blotting assay was used to test IGHG1 expression in OC cells. Viability of OC cells was tested by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide(MTT)assay. Flow cytometry or western blotting assay was used to detect cell cycle and apoptosis. Cellular motility was analyzed by using transwell assay and the markers of epithelial-mesenchymal transition(EMT) were tested through immunoblots.Results: Although it exerts negligible effect on the viability and apoptosis of OC cells, IGHG1 could promote migration and invasion of malignant cells in vitro. Mechanistically, IGHG1 increases the expression of N-cadherin and Vimentin while decreases E-cadherin expression. Additionally, IGHG1 expression in OC specimens is higher relative to the paired normal counterparts. Further analysis demonstrates that the increased IGHG1 expression correlates positively with the lymph node metastasis of OC.Conclusions: IGHG1 promotes the motility of OC cells likely through executing the EMT program. Increased IGHG1 expression in OC specimens is associated with the lymph node metastasis. | Jingfeng Qian Fangxing Ji Xue Ye Hongyan Cheng Ruiqiong Ma Xiaohong Chang Chengchao Shou Heng Cui | 2018 | Chinese Journal of Cancer Research2018，30，2： | 6 |
| 3 | The RppC-AvrRppC NLR-effector interaction mediates the resistance to southern corn rust in maize显示文摘Southern corn rust(SCR),caused by the fungal pathogen Puccinia polysora,is a major threat to maize pro-duction worldwide.Efficient breeding and deployment of resistant hybrids are key to achieving durable control of SCR.Here,we report the molecular cloning and characterization of RppC,which encodes an NLR-type immune receptor and is responsible for a major SCR resistance quantitative trait locus.Further-more,we identified the corresponding avirulence effector,AvrRppC,which is secreted by P.polysora and triggers RppC-mediated resistance.Allelic variation of AvrRppC directly determines the effectiveness of RppC-mediated resistance,indicating that monitoring of AvrRppC variants in the field can guide the rational deployment of RppC-containing hybrids in maize production.Currently,RppC is the most frequently deployed SCR resistance gene in China,and a better understanding of its mode of action is crit-ical for extending its durability. | Ce Deng April Leonard James Cahill Meng Lv Yurong Li Shawn Thatcher Xueying Li Xiaodi Zhao Wenjie Du Zheng Li Huimin Li Victor Llaca Kevin Fengler Lisa Marshall Charlotte Harris Girma Tabor Zhimin Li Zhiqiang Tian Qinghua Yang Yanhui Chen Jihua Tang Xintao Wang Junjie Hao Jianbing Yan Zhibing Lai Xiaohong Fei Weibin Song Jinsheng Lai Xuecai Zhang Guoping Shu Yibo Wang Yuxiao Chang Weiling Zhu Wei Xiong Juan Sun Bailin Li Junqiang Ding | 2022 | Molecular Plant2022，15，5： | 6 |
| 4 | In situ observation of C_(60)(C(COOH)_(2))_(2) interacting with living cells using fluorescence microscopy显示文摘The interactions between nanoparticles and living cells were investigated by an imaging technique of fluorescence microscopy. For this pur- pose, the C60 derivative C60(C(COOH)2)2, a thera- peutic agent for degeneration diseases of central nervous system, was synthesized, purified and characterized. Its interaction with the living cell and penetration of the cellular membrane were in situ studied using the real time imaging technique, and its potential cytotoxicity was also examined by flow cy- tometry. The results indicate that C60(C(COOH)2)2 can easily enter cells, and is mainly located in cytoplasm by fluorescein labeling. Furthermore, C60(C(COOH)2)2 can carry the molecule that cannot cross cellular membranes into cells, because fluo- rescein compound itself cannot enter the cell or ad- here to membrane. At concentrations ranging from 1×10?2 to 1×102 mg/L, C60(C(COOH)2)2 does not show any detectable cytotoxicity. | YE Chang CHEN Chunying CHEN Zhen MENG Huan XING Li JIANG Yaxin YUAN Hui XING Gengmei ZHAO Feng ZHAO Yuliang CHAI Zhifang FANG Xiaohong HAN Dong CHEN Long WANG Chen WEI Taotao | 2006 | Chinese Science Bulletin2006，51，9： | 4 |
| 5 | Evaluation of COC183B2 antibody targeting ovarian cancer by near-infrared fluorescence imaging显示文摘Objective: To evaluate the imaging potential of a novel near-infrared(NIR) probe conjugated to COC183 B2 monoclonal antibodies(MAb) in ovarian cancer(OC).Methods: The expression of OC183 B2 antigen in OC was determined by immunohistochemical(IHC) staining using tissue microarrays with the H-score system and immunofluorescence(IF) staining of tumor cell lines.Imaging probes with the NIR fluorescent dye cyanine 7(Cy7) conjugated to COC183 B2 Mab were chemically engineered. OC183 B2-positive human OC cells(SKOV3-Luc) were injected subcutaneously into BALB/c nude mice. Bioluminescent imaging(BLI) was performed to detect tumor location and growth. COC183 B2-Cy7 at 1.1,3.3, 10, or 30 μg were used for in vivo fluorescence imaging, and phosphate-buffered saline(PBS), free Cy7 dye and mouse isotype immunoglobulin G(IgG)-Cy7(delivered at the same doses as COC183 B2-Cy7) were used as controls.Results: The expression of OC183 B2 with a high H-score was more prevalent in OC tissue than fallopian tube(FT) tissue. Among 417 OC patients, the expression of OC183 B2 was significantly correlated with the histological subtype, histological grade, residual tumor size, relapse state and survival status. IF staining demonstrated that COC183 B2 specifically expressed in SKOV3 cells but not HeLa cells. In vivo NIR fluorescence imaging indicated that COC183 B2-Cy7 was mainly distributed in the xenograft and liver with optimal tumor-to-background(T/B)ratios in the xenograft at 30 μg dose. The highest fluorescent signals in the tumor were observed at 96 h postinjection(hpi). Ex vivo fluorescence imaging revealed the fluorescent signals mainly from the tumor and liver. IHC analysis confirmed that xenografts were OC183 B2 positive.Conclusions: COC183 B2 is a good candidate for NIR fluorescence imaging and imaging-guided surgery in OC. | Chen Zhang Xinyu Ling Yanxiu Guo Cunzhong Yuan Hongyan Cheng Xue Ye Ruiqiong Ma Yinli Zhang Yi Li Xiaohong Chang Beihua Kong Tao Liu Heng Cui | 2019 | Chinese Journal of Cancer Research2019，31，4： | 4 |
| 6 | Effect of SiC Location on the Ablation of C/C-SiC Composites in Two Heat Fluxes显示文摘How layer-segregated distribution of SiC affects the ablation of C/C-SiC composites was studied in the present work.A certain amount of SiC particles was deposited at the non-woven(C/C—SiC-1) and web(C/C-SiC-2) layer of 2D needle-punched carbon fibre fabric reinforced pyrocarbon composites,respectively.Ablation under oxyacetylene torch demonstrated that the two composites have similar ablation rates in heat flux of 2.38 MW/m^2 whereas ablation rates of C/C-SiC-2 were much higher than those of C/C—SiC-1 when heat flux was 4.18 MW/m^2.SiO_2 covered partially the defective surface of both composites in the lower heat flux.The different SiC locations induced distinct defects and then led to the two composites' dissimilar ablation rates in the higher heat flux. | Lei Liu Hejun Li Kui Hao Xiaohong Shi Kezhi Li Chang Ni | 2015 | Journal of Materials Science & Technology2015，31，4： | 3 |
| 7 | Comprehensive diag”nostic review of the (13)~C-enriched crude oils exemplified by TD2∈ and TZ62S in Tarim Basin, NW China显示文摘The crude oils typically from the CambrianLower Ordovician source rocks of Tarim Basin, NW'China, such as TD2 and TZ62S, are13C-enriched with the stable carbon isotopic ratios(VPDB) approaching-28 %.In this paper, the main research viewpoints on this issue are summarized, and combined with results from organic and inorganic carbon isotope stratum curves of the outcrop at the Ya'erdang Mountain in Tarim Basin. In addition, more alternative interpretations are discussed. On one hand, the inverse fractionation features of stable carbon and hydrogen isotopes of these crude oils may imply their protogenous nature. On the other hand, the anisotropy of source rocks and contribution from older stratum source rocks need verifying as well. For the sake of the final resolution of this issue, some further study topics are recommended. | Hu Liu Zewen Liao Haizu Zhang Yankuan Tian Bin Cheng Xiaohong Chang | 2015 | Chinese Journal Of Geochemistry2015，34，1： | 3 |

| 9 | Combined detection and subclass characteristics analysis of CTCs and CTECs by SE-iFISH in ovarian cancer显示文摘Objective:Hematogenous metastasis is essential for the progression of ovarian cancer(OC),and circulating tumor cells(CTCs)are part of the metastatic cascade.However,the detection rate of CTC is low due to the use of less sensitive detection methods.Therefore,this study aimed to detect CTCs and circulating tumorigenic endothelial cells(CTECs)in patients with OC using subtraction enrichment and immunostaining and fluorescence in situ hybridization(SE-iFISH).Methods:We enrolled a total of 56 subjects,including 20 OC patients and 36 ovarian benign tumor patients.CTCs and CTECs were captured by subtraction enrichment(SE)and counted and classified according to immunofluorescence staining of tumor markers(TMs)carbohydrate antigen 125(CA125)and human epididymis protein 4(HE4)combined with fluorescence in situ hybridization(iFISH)of chromosome 8(Chr8)aneuploidy.The diagnostic value and subtype characteristics of CTCs and CTECs were investigated.Results:The detection rate of CTCs by SE-iFISH was high.Compared with CA125 and HE4,Chr8 aneuploidy was the major identification feature of CTC.CTC counts in OC were statistically higher than those in benign groups.CTC and CTEC with≥pentaploidy were detected in both groups,illustrating the poor diagnostic value of CTC or CTEC.Distributions of triploid and tetraploid CTC subtypes were significantly different,and combined detection of triploid and tetraploid CTCs showed the best diagnostic value.In contrast,the distribution of CTECs in the OC and benign groups had no statistically significant difference.Small CTCs accounted for over 1/3 of the total CTC count.We also found that small CTCs and CTECs primarily comprised triploid cells,while large CTCs and CTECs mainly comprised pentaploidy and beyond.Conclusions:The application of SE-iFISH offered a more comprehensive understanding of heterogeneous CTCs and CTECs in OC.Analysis of subclass characteristics of the CTCs and CTECs according to Chr8 aneuploidy and cell size may broaden their potential clinical utility and deepen mechanistic studies in OC. | Hongyan Cheng Shang Wang Wenqing Luan Xue Ye Sha Dou Zhijian Tang Honglan Zhu Peter Ping Lin Yi Li Heng Cui Xiaohong Chang | 2021 | Chinese Journal of Cancer Research2021，33，2： | 3 |
| 10 | The Comparison of Genetic Variation in the Envelope Protein Between Various Immunodeficiency Viruses and Equine Infectious Anemia Virus显示文摘The envelope protein(Env) of lentiviruses such as HIV,SIV,FIV and EIAV is larger than that of other retroviruses.The Chinese EIAV attenuated vaccine is based on Env and has helped to successfully control this virus,demonstrating that envelope is crucial for vaccine.We compared Env variation of the four kinds of lentiviruses.Phylogenetic analysis showed that the evolutionary relationship of Env between HIV and SIV was the closest and they appeared to descend from a common ancestor,and the relationship of HIV and EIAV was the furthest.EIAV had the shortest Env length and the least number of potential N-linked glycosylation sites(PNGS) as well as glycosylation density compared to various immunodeficiency viruses.However,HIV had the longest Env length and the most PNGS.Moreover,the alignment of HIV and SIV showed that PNGS were primarily distributed within extracellular membrane protein gp120 rather than transmembrane gp41.It implies that the size difference among these viruses is associated with a lentivirus specific function and also the diversity of env.There are low levels of modification of glycosylation sites of Env and selection of optimal protective epitopes might be useful for development of an effective vaccine against HIV/AIDS. | Qing Yuan Chang Liu Zhipin Liang Xueqing Chen Danhong Diao Xiaohong Kong | 2012 | Virologica Sinica2012，27，4： | 3 |

| 12 | ALK gene expression status in pleural effusion predicts tumor responsiveness to crizotinib in Chinese patients with lung adenocarcinoma显示文摘Objective: The relationship between anaplastic lymphoma kinase(ALK) expression in malignant pleural effusion(MPE) samples detected only by Ventana immunohistochemistry(IHC) ALK(D5F3) and the efficacy of ALKtyrosine kinase inhibitor therapy is uncertain.Methods: Ventana anti-ALK(D5F3) rabbit monoclonal primary antibody testing was performed on 313 cell blocks of MPE samples from Chinese patients with advanced lung adenocarcinoma, and fluorescence in situ hybridization(FISH) was used to verify the ALK gene status in Ventana IHC ALK(D5F3)-positive samples. The follow-up clinical data on patients who received crizotinib treatment were recorded.Results: Of the 313 MPE samples, 27(8.6%) were confirmed as ALK expression-positive, and the Ventana IHC ALK(D5F3)-positive rate was 17.3%(27/156) in wild-type epidermal growth factor receptor(EGFR) MPE samples. Twenty-three of the 27 IHC ALK(D5F3)-positive samples were positive by FISH. Of the 11 Ventana IHC ALK(D5F3)-positive patients who received crizotinib therapy, 2 patients had complete response(CR), 5 had partial response(PR) and 3 had stable disease(SD).Conclusions: The ALK gene expression status detected by the Ventana IHC ALK(D5F3) platform in MPE samples may predict tumor responsiveness to crizotinib in Chinese patients with advanced lung adenocarcinoma. | Zheng Wang Xiaonan Wu Xiaohong Han Gang Cheng Xinlin Mu Yuhui Zhang Di Cui Chang Liu Dongge Liu Yuankai Shi | 2016 | Chinese Journal of Cancer Research2016，28，6： | 1 |
| 13 | Stability of HIV-1 subtype B and C Tat is associated with variation in the carboxyl-terminal region显示文摘The multifunctional trans-activator Tat is an essential regulatory protein for HIV-1 replication and is characterized by high sequence diversity. Numerous experimental studies have examined Tat in HIV-1 subtype B, but research on subtype C Tat is lacking, despite the high prevalence of infections caused by subtype C worldwide. We hypothesized that amino acid differences contribute to functional differences among Tat proteins. In the present study, we found that subtype B NL4-3Tat and subtype C isolate HIV1084 i Tat exhibited differences in stability by overexpressing the fusion protein Tat-Flag. In addition, 1084 i Tat can activate LTR and NF-κB more efficiently than NL4-3 Tat. In analyses of the activities of the truncated forms of Tat, we found that the carboxylterminal region of Tat regulates its stability and transactivity. According to our results, we speculated that the differences in stability between B-Tat and C-Tat result in differences in transactivation ability. | Xuechao Zhao Lingyu Qian Deyu Zhou Di Qi Chang Liu Xiaohong Kong | 2016 | Virologica Sinica2016，31，3： | 1 |

| 16 | Two Retroviruses Packaged in One Cell Line can Combined Inhibit the Replication of HIV-1 in TZM-bl Cells显示文摘The cellular protein tetherin tethers the HIV-1 viral particles on the cellular membrane to inhibit the replication of HIV-1.However,the HIV-1 accessory protein Vpu counteracts the antiviral function of tetherin.In this study,two retroviral vector plasmids were constructed.One inhibited the vpu gene expression;the other one over-expressed the tetherin.Both retroviral vector plasmids could be packaged in the packaging cell line PT67 to obtain the corresponding retroviruses.The retroviral vector plasmids' functions of tetherin over-expression or vpu-RNAi were detected at the cell level.Retroviral vector plasmids were transfected to PT67 cells at different ratios from 0T3V to 3T0V,and then mixed retroviruses were harvested.The antiviral functions of mixed retroviruses were detected in HIV-1 infected TZM-bl cells.The results showed that packaged mixed retroviruses could repress the replication of HIV-1 in TZM-bl cells. | Zhipin Liang Zhiyuan Guo Xin Wang Xiaohong Kong Chang Liul | 2012 | Virologica Sinica2012，27，6： | 1 |

| 20 | Evaluation of pharmacokinetics underlies the collaborated usage of lamivudine and oxymatrine in beagle dogs显示文摘Combinational therapy of lamivudine and oxymatrine has been employed in the battle against hepatitis B virus in clinical setting. However, the pharmacokinetic behavior of the drug or active metabolism in intravenous/oral co-administration regime is poorly investigated. Herein,we evaluated the pharmacokinetic characteristic through a tailor-designed 3 way crossoverLatin square experiment in adult male beagle dogs. Six dogs were randomly treated by intravenous administration of lamivudine(2.5 mg/kg), oxymatrine(15 mg/kg) and combinational dosage, named as intravenous regime. Meanwhile the other six dogs were orally administrated with lamivudine(2.5 mg/kg), oxymatrine(15 mg/kg) and combinational dosage,named as oral regime. The pharmacokinetic feature in simultaneous oral treatment appeared to have no significant difference when compared with individual administration,even including matrine, the active metabolite of oxymatrine. In intravenous regime, the main pharmacokinetic parameters of simultaneous administration were nearly consistent with intravenous regime remedy. The collaborated application of lamivudine and oxymatrine contributed to non-distinctive pharmacokinetic fluctuations of beagle dogs in intravenous/oral regime, compared with individual employment, which established a vital base for the clinical co-administration against hepatitis B. Furthermore, the present study demonstrated that the determination of pharmacokinetics between combinational and individual therapy might assist in the development of drug compatibility in clinical therapy. | Zhenbao Li Lei Shang Chang Liu Panqin Ma Chunnuan Wu Wenjuan Zhang Yinghua Sun Yongjun Wang Xiaohong Liu Jin Sun | 2016 | Asian Journal of Pharmaceutical Sciences2016，11，5： | 1 |
