2Geochronology and Nd and Pb isotope characteristics of gabbro dikes in the Luobusha ophiolite, Tibet显示文摘We report a combined internal and whole-rock Sm-Nd isochron age, and Nd and Pb isotopic data for gabbro dikes of the Luobusha ophiolite in Tibet. The Sm-Nd isochron of data for two whole rocks and plagioclase and clinopyroxene separates from one of the rocks yields a Middle Jurassic age of (177±31) Ma (with an initial εNd(t) = +8), which provides a significant bound on the time of formation of the Luobusha ophiolite. The Nd and Pb isotopic charac-teristics of the dike indicate an Indian-Ocean-type isotopic affinity, and we conclude that the Luobusha ophiolite formed in an oceanic setting during the Middle Jurassic.ZHOU Su MO Xuanxue J.J.Mahoney ZHANG Shuangquan GUO Tieyjing ZHAO Zhidan 2002Chinese Science Bulletin2002,47,2:38
3Immunohistochemical study on p53,H-rasp21,c-erbB-2 protein and PCNA expression in HCC tissues of Hart and minority ethnic patients显示文摘AIM To find out the difference of humanprimary liver carcinogenesis between Han andminority ethnic patients in Xinjiang.METHODS Expression of p53,c-erbB-2,H-rasp21 protein and proliferating cell nuclearantigen(PCNA)in tumor tissues of 50 patients(Han 38,minority 12)with primary hepaticcarcinoma was detected byimmunohistochemistry(LSAB).RESULTS The positive frequency of p53,c-erbB-2,H-rasp21 and PCNA expression was46.0%(23/50),70.0%(35/50),68.0%(34/50)and 82.0%(41/50)in tumor tissues;4.0%(2/50),22.0%(11/50),64.0%(32/50)and 52.0%(26/ 50)in peritumors respectively and asignificant difference,except for H-rasp21,ofoncogene alteration was found(P<0.05)between tumor and non-tumorous tissues.Combined the three oncogenes alteration,26%(13/50)tumor tissues had positiveimmunoreactivity,but in peritumor and normallivers it was negative.The positive rate of p53,c-erbB-2 and H-rasp21 protein expression was39.5%(15/38),60.5%(23/38)and 39.5%(15/38)in tumors of Han patients;66.7%(8/12),100%(12/12)and 75.0%(9/12)in minoritiesrespectively,with statistical difference (P<0.05).CONCLUSION Overexpression of p53,c-erbB-2and H-rasp21 in human primary liver carcinoma isan important biomarker of genetic alteration.The different frequency of these oncogeneticchanges may reflect some environmental or/andethnic hereditary factors affecting the livercarcinogenesis.The special life style of Han,Uygur,Kazak and Mongolia nationalities inXinjiang may also be related to theetiopathogenesis of this disease.Guo Yue Lin Zhao Lun Chen Cai Mo Lu Ying Li Xiao Jia Ping Rong Huang Department of Laboratory Medicine,Chinese PLA 474 Hospital,Urumqi 830011,Xinjiang Uygur Autonomic Region,China Department of Pathology,the 1st Teaching Hospital,Xinjiang Medical University,Urumqi 830054,Xinjiang Uygur Autonomic Region,China 2000World Journal of Gastroenterology2000,6,2:40
4Active phase compensation of quantum key distribution system显示文摘Quantum key distribution (QKD) system must be robust enough in practical communication. Besides birefringence of fiber, system performance is notably affected by phase drift. The Faraday-Michelson QKD system can auto-compensate the birefringence of fiber, but phase shift is still a serious problem in its practical operation. In this paper, the major reason of phase drift and its effect on Faraday- Michel- son QKD system is analyzed and an effective active phase compensation scheme is proposed. By this means, we demonstrate a quantum key distribution system which can stably run over 37-km fiber in practical working condition with the long-time averaged quantum bit error rate of 1.59% and the stan- dard derivation of 0.46%. This result shows that the active phase compensation scheme is suitable to be used in practical QKD systems based on double asymmetric interferometers without additional de- vices and thermal controller.CHEN Wei HAN ZhengFu MO XiaoFan XU FangXing WEI Guo GUO GuangCan 2008Chinese Science Bulletin2008,53,9:24

6Changing patterns and survival improvements of young breast cancer in China and SEER database, 1999-2017显示文摘Objective: Breast cancer in young females was usually considered more aggressive and requires aggressive therapy. We investigated whether early detection and improved treatments changed the patterns of characteristics,management and outcomes of young breast cancer patients over time.Methods: Females under 40 years of age diagnosed with breast cancer during the periods 1999-2017 and1999-2015 were identified in the Fudan University Shanghai Cancer Center(FUSCC) and the population-based Surveillance, Epidemiology, and End Results(SEER) registry, respectively. Clinicopathologic characteristics and treatment information were collected. Patients diagnosed before 2013 were followed up.Results: The proportions of young breast cancer patients were 15.0% and 5.3% in the FUSCC and SEER cohorts, respectively. In the FUSCC cohort, there was a significant increase in the proportion of ductal carcinoma in situ(DCIS)(from 8.8% to 16.9%;P<0.0001) and it remained stable in SEER cohort. The proportion of T1-stage tumors increased dramatically in the FUSCC cohort(from 35.3% to 41.9%;P=0.008), whereas it decreased in SEER cohort(from 42.4% to 33.0%;P<0.0001). The percentage of estrogen receptor(ER)-positive cancers was consistently increased in both the invasive ductal carcinoma(IDC) and DCIS patients in the two cohorts. Breastconserving surgery and immediate implant reconstruction after mastectomy both exhibited increased use over time in the FUSCC cohort. Both the FUSCC and SEER cohorts showed a significantly better prognosis in the recent time period.Conclusions: With the increased early-stage and ER-positive diseases in young patients as well as better systemic treatment strategies, improved survival has been observed in recent years. There has been a substantial deescalation in surgical therapies in young breast cancer patients.Rong Guo Jing Si Jingyan Xue Yonghui Su Miao Mo Benlong Yang Qi Zhang Weiru Chi Yayun Chi Jiong Wu 2019Chinese Journal of Cancer Research2019,31,4:24
7Efficient InGaN-based yellow-light-emitting diodes显示文摘Realization of efficient yellow-light-emitting diodes(LEDs) has always been a challenge in solid-state lighting.Great effort has been made, but only slight advancements have occurred in the past few decades. After comprehensive work on InGaN-based yellow LEDs on Si substrate, we successfully made a breakthrough and pushed the wall-plug efficiency of 565-nm-yellow LEDs to 24.3% at 20 A∕cm^2 and 33.7% at 3 A∕cm^2. The success of yellow LEDs can be credited to the improved material quality and reduced compressive strain of InGaN quantum wells by a prestrained layer and substrate, as well as enhanced hole injection by a 3 D pn junction with V-pits.FENGYI JIANG JIANLI ZHANG LONGQUAN XU JIE DING GUANGXU WANG XIAOMING WU XIAOLAN WANG CHUNLAN MO ZHIJUE QUAN XING GUO CHANGDA ZHENG SHUAN PAN JUNLIN LIU 2019Photonics Research2019,7,2:13

9Dynamic immune profiling identifies the stronger graft-versus-leukemia (GVL) effects with haploidentical allografts compared to HLA-matched stem cell transplantation显示文摘Haploidentical stem cell transplantation(haplo-SCT)achieves superior or at least comparable clinical outcomes to HLA-matched sibling donor transplantation(MSDT)in treating hematological malignancies.To define the underlying regulatory dynamics,we analyzed time courses of leukemia burden and immune abundance of haplo-SCT or MSDT from multiple dimension.First,we employed two nonirradiated leukemia mouse models which carried human AML-ETO or MLL-AF9 fusion gene to establish haplo-identical and major histocompatibility(MHC)-matched transplantation models and investigated the immune cell dynamic response during leukemia development in vivo.We found that haplo-matching the MHCs of leukemia cells with recipient mouse T cells prolonged leukemic mice survival and reduced leukemia burden.The stronger graft-versus-leukemia activity in haplo-SCT group mainly induced by decreased apoptosis and increased cytotoxic cytokine secretion including tumor necrosis factor–α,interferon-γ,pore-forming proteins and CD107a secreted by T cells or natural killer cells.Furthermore,we conducted a prospective clinical trial which enrolled 135 patients with t(8;21)acute myeloid leukemia that displayed minimal residual disease before transplantation and underwent either haplo-SCT or MSDT.The results showed that the haplo-SCT slowed the kinetics of the leukemia burden in vivo and reduced the cumulative incidence of relapse compared with MSDT.Ex vivo experiments showed that,1 year after transplantation,cytotoxic T lymphocytes from the haplo-SCT group had higher cytotoxicity than those from the MSDT group during the same period.Our results unraveled the role of immune cells in superior antileukemia effects of haplo-SCT compared with MSDT.Huidong Guo Ying-Jun Chang Yan Hong Lan-Ping Xu Yu Wang Xiao-Hui Zhang Ming Wang Huan Chen Yu-Hong Chen Feng-Rong Wang Wei-Han Yu-Qian Sun Chen-Hua Yan Fei-Fei Tang Xiao-Dong Mo Kai-Yan Liu Xiao-Jun Huang 2021Cellular & Molecular Immunology2021,18,5:11
10Innovative Group-Decoupling Design of a Segment Erector Based on G_F Set Theory显示文摘The segment erector is a key part of the shield machines for tunnel engineering. The available segment erectors are all of serial configuration which is suffering from the problems of low rigidity and accumulative motion errors. The current research mainly focuses on improving assembly accuracy and control performance of serial segment erectors. An innovative design method is proposed featuring motion group-decoupling, based on which a new type of segment erector is developed and investigated. Firstly, the segment installation manipulation is analyzed and decomposed into three motion groups that are decoupled. Then the type synthesis for the 4-DOF motion group is performed based on the general function(GF) set theory and a new configuration of (1T?1R?1PS&3UPS) is attained according to the segment manipulation requirements. Consequently, the kinematic models are built and the reducibility and accuracy are analyzed. The dexterity is verified though numerical simulation and no singular points appear in the workspace. Finally, a positioning experiment is carried out by using the prototype developed in the lab that demonstrates a 13.1% improvement of positioning accuracy and the feasibility of the new segment erector. The presented group-decoupling design method is able to invent new type of hybrid segment erectors that avoid the accumulative motion error of erecting.GUO Wentao GUO Weizhong GAO Feng MO Pinxi 2013Chinese Journal of Mechanical Engineering2013,26,2:10

12Development and validation of an endoscopic images-based deep learning model for detection with nasopharyngeal malignancies显示文摘Background:Due to the occult anatomic location of the nasopharynx and frequent presence of adenoid hyperpla-sia,the positive rate for malignancy identification during biopsy is low,thus leading to delayed or missed diagnosis for nasopharyngeal malignancies upon initial attempt.Here,we aimed to develop an artificial intelligence tool to detect nasopharyngeal malignancies under endoscopic examination based on deep learning.Methods:An endoscopic images-based nasopharyngeal malignancy detection model(eNPM-DM)consisting of a fully convolutional network based on the inception architecture was developed and fine-tuned using separate training and validation sets for both classification and segmentation.Briefly,a total of 28,966 qualified images were collected.Among these images,27,536 biopsy-proven images from 7951 individuals obtained from January 1st,2008,to December 31st,2016,were split into the training,validation and test sets at a ratio of 7:1:2 using simple randomiza-tion.Additionally,1430 images obtained from January 1st,2017,to March 31st,2017,were used as a prospective test set to compare the performance of the established model against oncologist evaluation.The dice similarity coef-ficient(DSC)was used to evaluate the efficiency of eNPM-DM in automatic segmentation of malignant area from the background of nasopharyngeal endoscopic images,by comparing automatic segmentation with manual segmenta-tion performed by the experts.Results:All images were histopathologically confirmed,and included 5713(19.7%)normal control,19,107(66.0%)nasopharyngeal carcinoma(NPC),335(1.2%)NPC and 3811(13.2%)benign diseases.The eNPM-DM attained an overall accuracy of 88.7%(95%confidence interval(CI)87.8%-89.5%)in detecting malignancies in the test set.In the prospective comparison phase,eNPM-DM outperformed the experts:the overall accuracy was 88.0%(95%CI 86.1%-89.6%)vs.80.5%(95%CI 77.0%-84.0%).The eNPM-DM required less time(40 s vs.110.0±5.8 min)and exhibited encouraging performance in automatic segmentation of nasopharyngeal malignant area from the background,with an average DSC of 0.78±0.24 and 0.75±0.26 in the test and prospective test sets,respectively.Conclusions:The eNPM-DM outperformed oncologist evaluation in diagnostic classification of nasopharyngeal mass into benign versus malignant,and realized automatic segmentation of malignant area from the background of nasopharyngeal endoscopic images.Chaofeng Li Bingzhong Jing Liangru Ke Bin Li Weixiong Xia Caisheng He Chaonan Qian Chong Zhao Haiqiang Mai Mingyuan Chen Kajia Cao Haoyuan Mo Ling Guo Qiuyan Chen Linquan Tang Wenze Qiu Yahui Yu Hu Liang Xinjun Huang Guoying Liu Wangzhong Li Lin Wang Rui Sun Xiong Zou Shanshan Guo Peiyu Huang Donghua Luo Fang Qiu Yishan Wu Yijun Hua Kuiyuan Liu Shuhui Lv Jingjing Miao Yanqun Xiang Ying Sun Xiang Guo Xing Lv 2018Cancer Communications2018,38,1:9
13uPAR promotes tumor-like biologic behaviors of fibroblast-like synoviocytes through PI3K/Akt signaling pathway in patients with rheumatoid arthritis显示文摘Urokinase-type plasminogen activator receptor(uPAR),is a multifunctional receptor on cell surface,widely present in endothelial cells,fibroblasts,and a variety of malignant cells.Current studies have suggested that uPAR overexpressed on synovial tissues or in synovial fluid or plasma in patients with rheumatoid arthritis(RA).However,there are limited researches regarding the role of uPAR on fibroblast-like synoviocytes of rheumatoid arthritis(RA-FLSs)and its underlying mechanisms.Here,our studies show that the expression of uPAR protein was significantly higher in fibroblast-like synoviocytes(FLSs)from RA than those from osteoarthritis or traumatic injury patients.uPAR gene silencing significantly inhibited RA-FLSs cell proliferation,restrained cell transformation from the G0/G1 phase to S phase,aggravated cell apoptosis,interfered with RA-FLSs cell migration and invasion,and reduced activation of the PI3K/Akt signaling pathway,which may be associated withβ1-integrin.Cell supernatants from uPAR gene-silenced RA-FLSs markedly inhibited the migration and tubule formation ability of the HUVECs(a human endothelial cell line).Therefore,we demonstrate that uPAR changes the biological characteristics of RA-FLSs,and affects neoangiogenesis of synovial tissues in patients with RA.All of these may be associated with theβ1-integrin/PI3K/Akt signaling pathway.These results imply that targeting uPAR and its downstream signal pathway may provide therapeutic effects in RA.Yan Liu Yun Feng Pan You-qiu Xue Lin-kai Fang Xing-hua Guo Xin Guo Meng Liu Bi-yao Mo Meng-ru Yang Fang Liu Yun-ting Wu Nancy Olsen Song Guo Zheng 2018Cellular & Molecular Immunology2018,15,2:9
14Revisiting the sex pheromone of the fall armyworm Spodoptera frugiperda,a new invasive pest in South China显示文摘The fall armyworm Spodoptera frugiperda is a worldwide serious agricultural pest,and recently invaded South China.Sex pheromone can be employed to monitor its population dynamics accurately in the field.However,the pheromone components previously reported by testing different geographic populations and strains are not consistent.On the basis of confirming that the S.frugiperda population from Yunnan Province belonged to the com strain,we analyzed the potential sex pheromone components in the pheromone gland extracts of females using gas chromatography coupled with electroan-tennographic detection(GC-EAD),gas chromatography coupled with mass spectrometry(GC-MS)and electroantennography(EAG).The results show that(Z)-9-tetradecenal acetate(Z9-14:Ac),(Z)-11-hexadecenyl acetate(Z11-16:Ac),(Z)-7-dodecenyl acetate(Z7-12:Ac)or(E)-7-dodecenyl acetate(E7-12:Ac)with a ratio of 100:15.8:3.9 induced EAD responses to varying degrees:Z9-14:Ac elicited a strong EAD response,Z7-12:Ac or E7-12:Ac elicited a small but clear EAD response,while Z11-16:Ac elicited a weak EAD response.Further single sensillum recording(SSR)showed that Z9-14:Ac and Z7-12:Ac induced dose-dependent activities in two types(A and B)of sensilla in male antennae,respectively,while the sensilla in response to E7-12:Ac and Z11-16:Ac was not recorded.Finally,wind tunnel tests reveal that Z9-14:Ac and Z7-12:Ac are two principal sex pheromone components of the tested population.Nan-Ji Jiang Bao-Tong Mo Hao Guo Jun Yang Rui Tang Chen-Zhu Wang 2022Insect Science2022,29,3:8
15Association 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 2020Biomedical and Environmental Sciences2020,33,12:8
16Efficacy and safety of Yunxiangjing derived from Chinese herbal medicine administered as an enema in the management of acute radiation-induced proctitis in patients with pelvic malignancy显示文摘OBJECTIVE: To assess the efficacy and safety of Yunxiangjing(YXJ), derived from Chinese herbal medicine, in the management of acute radiation-induced proctitis(ARIP) in patients with pelvic malignancy.METHODS: Forty-eight patients with grade 2 ARIP were administered YXJ as an enema(1∶30 dilution)for 2 weeks and followed up for 2 years. All were assessed for response and ARIP grade. Quality of life(QOL) was assessed with the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire-Core 30.RESULTS: Of the 48 patients, six(12.5%) achieved complete remission of ARIP and 28(58.3%) showed a decrease from grade 2 to grade 1 ARIP. No patient experienced a grade ≥3 toxicity. At the end of radiotherapy, patients showed significant improvements in QOL(P < 0.05). Two years after treatment, 46 patients showed no late toxicity, with only two experiencing grade 1 late toxicity.CONCLUSION: YXJ can be used as an enema to manage acute radiation-induced proctitis in cancer patients undergoing radiotherapy.

17Formaldehyde concentration and its influencing factors in residential homes after decoration at Hangzhou,China显示文摘Air pollution surveys of formaldehyde(HCHO) were conducted in 2324 rooms decorated within one year in 2007-2009 in Hangzhou,China.The mean HCHO concentration(C HCHO) was 0.107 ± 0.095 mg/m 3,and 38.9% of samples exceeded the Chinese National Standard GB 50325-2010.Over the past 3 years,the C HCHO decreased with time(p < 0.05).Relationships of potential factors to indoor C HCHO were also evaluated.C HCHO was related to temperature(T),relative humidity(RH),time duration of the windows and doors being closed before sampling(DC),time duration from the end of decoration to sampling(DR) and source characteristics(d).A model to relate indoor C HCHO to these five factors(T,RH,DC,DR,d) was established based on 298 samples(R 2 = 0.87).Various factors contributed to C HCHO in the following order:T,43.7%;d,31.0%;DC,10.2%;DR,8.0%;RH,7.0%;specifically,meteorological conditions(i.e.,RH plus T) accounted for 50.7%.The coefficient of T and RH,R TH,was proposed to describe their combined influence on HCHO emission,which also had a linear relationship(R 2 = 0.9387) with HCHO release in a simulation chamber test.In addition,experiments confirm that it is a synergistic action as T and RH accelerate the release of HCHO,and that is a significant factor influencing indoor HCHO pollution.These achievements could lead to reference values of measures for the efficient reduction of indoor HCHO pollution.Min Guo Xiaoqiang Pei Feifei Mo Jianlei Liu Xueyou Shen 2013Journal of Environmental Sciences2013,25,5:7
18Randomized study of sinusoidal chronomodulated versus flat intermittent induction chemotherapy with cisplatin and 5-fluorouracil followed by traditional radiotherapy for locoregionally advanced nasopharyngeal carcinoma显示文摘Neoadjuvant chemotherapy plus radiotherapy is the most common treatment regimen for advanced nasopharyngeal carcinoma(NPC).Whether chronomodulated infusion of chemotherapy can reduce its toxicity is unclear.This study aimed to evaluate the toxic and therapeutic effects of sinusoidal chronomodulated infusion versus flat intermittent infusion of cisplatin(DDP)and 5-fluorouracil(5-FU)followed by radiotherapy in patients with locoregionally advanced NPC.Patients with biopsy-diagnosed untreated stages III and IV NPC(according to the 2002 UICC staging system)were randomized to undergo2 cycles of sinusoidal chronomodulated infusion(Arm A)or flat intermittent constant rate infusion(Arm B)of DDP and 5-FU followed by radical radiotherapy.Using a'MELODIE'multi-channel programmed pump,the patients were given 12-hour continuous infusions of DDP(20 mg/m2)and 5-FU(750 mg/m2)for 5days,repeated every 3 weeks for 2 cycles.DDP was administered from 10:00 am to 10:00 pm,and 5-FU was administered from 10:00 pm to 10:00 am each day.Chronomodulated infusion was performed in Arm A,with the peak deliveries of 5-FU at 4:00 am and DDP at 4:00 pm.The patients in Arm B underwent a constant rate of infusion.Radiotherapy was initiated in the fifth week,and both arms were treated with the same radiotherapy techniques and dose fractions.Between June 2004 and June 2006,125 patients were registered,and 124 were eligible for analysis of response and toxicity.The major toxicity observed during neoadjuvant chemotherapy was neutropenia.The incidence of acute toxicity was similar in both arms.During radiotherapy,the incidence of stomatitis was significantly lower in Arm A than in Arm B(38.1%vs.59.0%,P=0.020).No significant differences were observed for other toxicities.The 1-,3-,and 5-year overall survival rates were 88.9%,82.4%,and 74.8%for Arm A and 91.8%,90.2%,and 82.1%for Arm B.The 1-,3-,and 5-year progression-free survival rates were 91.7%,88.1%,and 85.2%for Arm A and 100%,94.5%,and 86.9%for Arm B.The 1-,3-,and 5-year distant metastasis-free survival rates were 82.5%,79.1%,and 79.1%for Arm A and 90.2%,85.2%,and 81.7%for Arm B.Chronochemotherapy significantly reduced stomatitis but was not superior to standard chemotherapy in terms of hematologic toxicities and therapeutic response.Huan-Xin Lin Yi-Jun Hua Qiu-Yan Chen Dong-Hua Luo Rui Sun Fang Qiu Hao-Yuan Mo Hai-Qiang Mai Xiang Guo Li-Jian Xian Ming-Huang Hong Ling Guo 2013Chinese Journal of Cancer2013,32,9:7
19Famitinib in combination with concurrent chemoradiotherapy in patients with locoregionally advanced nasopharyngeal carcinoma: a phase 1, open-label, dose-escalation Study显示文摘Background:Famitinib is a tyrosine kinase inhibitor against multiple targets,including vascular endothelial growth factor receptor 2/3,platelet-derived growth factor receptor,and stem cell factor receptor(c-kit).Previous studies have demonstrated anti-tumour activities of famitinib against a wide variety of advanced-stage solid cancers.We aimed to determine the safety and efficacy of famitinib with concurrent chemoradiotherapy(CCRT)in patients with locoregionally advanced nasopharyngeal carcinoma(NPC).We also evaluated the feasibility of contrast-enhanced ultrasound(D-CEUS)as a predictor of early tumour response to famitinib and to correlate functional parameters with clinical efficacy.Methods:The trial was conducted in subjects with stage III or IVa-b NPC using a 3+3 design of escalating fami-tinib doses.Briefly,subjects received 2 weeks of famitinib monotherapy followed by 7 weeks of famitinib plus CCRT.D-CEUS of the neck lymph nodes was performed at day 0,8 and 15 after famitinib was administered before starting concurrent chemoradiotherapy.End points included safety,tolerability and anti-tumour activity.Results:Twenty patients were enrolled(six each for 12.5,16.5 and 20 mg and two for 25 mg).Two patients in the 25 mg cohort developed dose-limiting toxicities,including grade 4 thrombocytopenia and grade 3 hypertension.The most common grade 3/4 adverse events were leukopenia,neutropenia and radiation mucositis.D-CEUS tests showed that more than 60%of patients achieved a perfusion parameter response after 2 weeks taking famitinib alone,and the parameter response was associated with disease improvement.In the famitinib monotherapy stage,three patients(15%)showed partial responses.The complete response rate was 65%at the completion of treatment and 95%3 months after the treatment ended.After a median follow-up of 44 months,the 3-year progression-free survival(PFS)and distant metastasis-free survival were 70%and 75%,respectively.Subjects with a decrease of perfusion parameter response,such as peak intensity decreased at least 30%after 1 week of famitinib treatment,had higher 3-year PFS(90.9%vs.44.4%,95%CI 73.7%-100%vs.11.9%-76.9%,P<0.001)than those with an increase or a reduction of less than 30%.Conclusions:The recommended famitinib dose for phase II trial is 20 mg with CCRT for patients with local advanced NPC.D-CEUS is a reliable and early measure of efficacy for famitinib therapies.Further investigation is required to confirm the effects of famitinib plus chemoradiotherapy.Qiuyan Chen Linquan Tang Na Liu Feng Han Ling Guo Shanshan Guo Jianwei Wang Huai Liu Yanfang Ye Lu Zhang Liting Liu Pan Wang Yingqin Li Qingmei He Xiaoqun Yang Qingnan Tang Yang Li YuJing Liang XueSong Sun Chuanmiao Xie Yunxian Mo Ying Guo Rui Sun Haoyuan Mo Kajia Cao Xiang Guo Musheng Zeng Haiqiang Mai Jun Ma 2018Cancer Communications2018,38,1:6
20Relationship between Ambient Fine Particles and Ventricular Repolarization Changes and Heart Rate Variability of Elderly People with Heart Disease in Beijing, China显示文摘Objective To explore the effects of particulate matters less than 2.5 μm in aerodynamic diameter (PM 2.5) on heart repolarization/depolarization and heart rate variability (HRV). Methods We conducted a panel study for elderly subjects with heart disease in Beijing from 2007 to 2008. PM 2.5 was measured at a fixed station for 20 h continuously each day while electrocardiogram (ECG) indexes of 42 subjects were also recorded repeatedly. Meteorological data was obtained from the China Meteorological Data Sharing Service System. A mixed linear regression model was used to estimate the associations between PM 2.5 and the ECG indexes. The model was adjusted for age, body mass index, sex, day of the week andmeteorology. Results Significant adverse effects of PM 2.5 on ECG indexes reflecting HRV were observed statistically and the strongest effect of PM 2.5 on HRV was on lag 1 day in our study. However, there were no associations between PM 2.5 and ECG indexes reflecting heart repolarization/depolarization. Additionally, the effects of PM 2.5 on subjects with hypertension were larger than on the subjects without hypertension. Conclusion This study showed ambient PM 2.5 could affect cardiac autonomic function of the elderly people with heart disease, and subjects with hypertension appeared to be more susceptive to the autonomic dysfunction induced by PM 2.5.XU Mei Mei JIA Yu Ping LI Guo Xing LIU Li Qun MO Yun Zheng JIN Xiao Bin PAN Xiao Chuan 2013Biomedical and Environmental Sciences2013,26,8:6
