| 1 | Prognostic evaluation of postoperative adjuvant therapy for operable cervical cancer:10 years'experience of National Cancer Center in China显示文摘Objective: The aim of this study was to investigate the prognostic factors and to evaluate the impact of adjuvant therapy on clinical outcome for early-stage cervical cancer.Methods: The clinical-pathological data of all 1,335 patients with the International Federation of Gynecology and Obstetrics(FIGO) Ib–IIa cervical cancer treated with primary radical surgery at the Chinese National Cancer Center between May 2007 and Dec 2013 were retrospectively reviewed.The median follow-up was 70 months.Results: Of all the patients,61.6% of the cases received adjuvant therapy,with 5-year disease-free survival(DFS)of 92.1% and 5-year overall survival(OS) of 95.0%.In multivariate analysis,differentiation of G3(P<0.05),lymph node metastasis(LNM,P<0.05) and lymphovascular space invasion(LVSI,P<0.05) were independent predictors for OS,while LNM(P<0.05),deep stroma invasion(DSI,P<0.05) and LVSI(P<0.05) were independent factors for DFS.The samples were stratified by histologic type,and cervical squamous cell carcinoma(SCC) was found to share the same independent factors except for differentiation of OS.As to patients with cervical adenocarcinoma/adenosquamous carcinoma(AC/ASC),differentiation was the independent predictor of OS(P<0.05); and LVSI of DFS(P<0.05).Of 236 patients with high-risk factors,there was no significant difference in survival between concurrent chemoradiotherapy(CCRT,n=195),radiotherapy(RT,n=24),and chemotherapy(CT,n=17).Among the 190 patients with LNM who underwent CCRT,124 cases showed improved DFS after sequential CT(P=0.118),with a recurrence rate decrease of 14%,though the difference was not statistically significant.Patients with single intermediate-risk factors like DSI or LVSI were found to partially benefit from adjuvant therapy,but the difference was not statistically significant.Conclusions: LNM,LVSI,DSI and differentiation were found to be independent prognostic factors for operable cervical cancer.Aggressive postoperative adjuvant therapy based on single risk factors in Chinese National Cancer Center could benefit survival.CCRT+CT outperformed CCRT in high-risk patients.For patients with single non-high-risk factor,the role of adjuvant therapy needs to be further discussed. | Tong Shu Dan Zhao Bin Li Yating Wang Shuanghuan Liu Pingping Li Jing Zuo Ping Ba i RongZhang Lingying Wu | 2017 | Chinese Journal of Cancer Research2017，29，6： | 12 |
| 2 | Asphaltenes: Separations, structural analysis and applications显示文摘Asphaltenes, complex aromatic compounds from various carbonaceous sources, could be obtained by solvent dissolution, filtration and adsorption. It was difficult to clarify the molecular structures and chemical properties of asphaltene due to its structural similarity, composition complexity and source dependences. Many techniques, like Mass spectrometry, Chromatography, Nuclear magnetic resonance spectroscopy, Infrared spectroscopy, Roman spectroscopy, Fluorescence spectroscopy, X-ray diffraction analysis and Small-angle scattering techniques and so on, have revealed some valuable descriptions of asphaltenes chemical compositions and fundamental structures. Moreover, advanced Mass spectrometry,Atomic force microscopy and Scanning tunneling microscopy could provide more clear and essential molecular compounds and structures in asphaltenes. In addition, several asphaltenes models have succeeded to illustrate aggregation properties asphaltene. In this work, the progress on asphaltene separation, characterization and application was summarized, and the similarities and differences between coal-derived asphaltenes and petroleum asphaltenes were compared. Furthermore, the reactivity of asphaltenes has been discussed in the aspect of hydroprocessing, pyrolysis and gasification. Asphaltene was excellent carbon precursor for functional carbon material due to its high aromaticity and carbon yield;several porous carbon nanosheets from asphaltenes that would be prospective electrode materials after being graphitized were shown. Pitch-based carbon fiber derived from coal-derived asphaltenes displayed a tensile strength of 1.0 GPa and elastic modulus of 350 MPa, respectively. These powerful advances will provide asphaltenes promising developments. | Pingping Zuo Shijie Qu Wenzhong Shen | 2019 | Journal of Energy Chemistry2019，28，7： | 7 |
| 3 | Anti-parkinsonian effects of octacosanol in 1-methyl-4-phenyl-1,2,3,6 tetrahydropyridine-treated mice显示文摘Our previous research showed that octacosanol exerted its protective effects in 6-hydroxydopamine-induced Parkinsonian rats. The goal of this study was to investigate whether octacosanol would attenuate neurotoxicity in 1-methyl-4-phenyl-1,2,3,6 tetrahydropyridine (MPTP)-treated C57BL/6N mice and its potential mechanism. Behavioral tests, tyrosine hydroxylase immunohistochemistry and western blot were used to investigate the effects of octacosanol in a mouse model of Parkinson's disease. Oral administration of octacosanol (100 mg/kg) significantly improved behavioral impairments in mice treated by MPTP and markedly ameliorated morphological appearances of tyrosine hydroxylase-positive neuronal cells in the substantia nigra. Furthermore, octacosanol blocked MPTP-induced phosphorylation of p38MAPK and JNK, but not ERK1/2. These findings implicated that the protective effects afforded by octacosanol might be mediated by blocking the phosphorylation of p38MAPK and JNK on the signal transduction in vivo. Considering its excellent tolerability, octacosanol might be considered as a candidate agent for clinical application in treating Parkinson's disease. | Tao Wang Yanyong Liu Nan Yang Chao Ji Piu Chan Pingping Zuo | 2012 | Neural Regeneration Research2012，7，14： | 7 |

| 9 | Reliability Modeling and Evaluation of Complex Multi-State System Based on Bayesian Networks Considering Fuzzy Dynamic of Faults显示文摘In the traditional reliability evaluation based on the Bayesian method,the failure probability of nodes is usually expressed by the average failure rate within a period of time.Aiming at the shortcomings of traditional Bayesian network reliability evaluation methods,this paper proposes a Bayesian network reliability evaluation method considering dynamics and fuzziness.The fuzzy theory and the dynamic of component failure probability are introduced to construct the dynamic fuzzy set function.Based on the solving characteristics of the dynamic fuzzy set and Bayesian network,the fuzzy dynamic probability and fuzzy dynamic importance degree of the fault state of leaf nodes are solved.Finally,through the dynamic fuzzy reliability analysis of CNC machine tool hydraulic system balance circuit,the application of this method in system reliability evaluation is verified,which provides support for fault diagnosis of CNC machine tools. | Fangjun Zuo Meiwei Jia Guang Wen Huijie Zhang Pingping Liu | 2021 | Computer Modeling in Engineering & Sciences2021，，11： | 0 |
