1Efficacy and safety of a novel anti-HER2 therapeutic antibody RC48 in patients with HER2-overexpressing,locally advanced or metastatic gastric or gastroesophageal junction cancer:a single-arm phase II study显示文摘Background:Current treatment options for human epidermal growth factor receptor 2(HER2)-overexpressing gastric cancer at third-line have shown limited clinical benefit.Further,there is no specific treatment for HER2 immunohistochemistry(IHC)2+and fluorescence in-situ hybridization-negative patients.Here,we report the efficacy and safety of a novel anti-HER2 antibody RC48 for patients with HER2-overexpressing,advanced gastric or gastroesophageal junction cancer.Methods:Patients with HER2-overexpressing(IHC 2+or 3+),locally advanced or metastatic gastric or gastroesophageal junction cancer who were under at least second-line therapy were eligible and received RC482.5 mg/kg alone every 2 weeks.The primary endpoint was the objective response rate(ORR)assessed by an independent review committee.Secondary endpoints included progressionfree survival(PFS),overall survival(OS),duration of response,time to progression,disease control rate,and safety.Results:Of 179 patients screened,125 were eligible and received RC48 treatment.The ORR was 24.8%(95%confidence interval[CI]:17.5%-33.3%).The median PFS and OS were 4.1 months(95%CI:3.7-4.9 months)and 7.9 months(95%CI:6.7-9.9 months),respectively.The most frequently reported adverse events were decreased white blood cell count(53.6%),asthenia(53.6%),hair loss(53.6%),decreased neutrophil count(52.0%),anemia(49.6%),and increased aspartate aminotransferase level(43.2%).Serious adverse events(SAEs)occurred in 45(36.0%)patients,and RC48-related SAEs were mainly decreased neutrophil count(3.2%).Seven patients had adverse events that led to death were not RC48-related.Conclusions:RC48 showed promising activity with manageable safety,suggesting potential application in patients with HER2-overexpressing,advanced gastric or gastroesophageal junction cancer who have previously received at least two lines of chemotherapy.Zhi Peng Tianshu Liu Jia Wei Airong Wang Yifu He Liuzhong Yang Xizhi Zhang Nanfeng Fan Suxia Luo Zhen Li Kangsheng Gu Jianwei Lu Jianming Xu Qingxia Fan Ruihua Xu Liangming Zhang Enxiao Li Yuping Sun Guohua Yu Chunmei Bai Yong Liu Jiangzheng Zeng Jieer Ying Xinjun Liang Nong Xu Chao Gao Yongqian Shu Dong Ma Guanghai Dai Shengmian Li Ting Deng Yuehong Cui Jianmin Fang Yi Ba Lin Shen 2021Cancer Communications2021,41,11:29
2Histological Subtypes of Lung Cancer in Chinese Males from 2000 to 2012显示文摘Objective To characterize the histological and epidemiological features of male lung cancer patients in China. Methods The demographic and histological information about male lung cancer patients identified from 2000-01-01 to 2012-12-31,was collected from the Cancer Hospital of the Chinese Academy of Medical Sciences. Relative frequencies(RF) were estimated for major histological subtypes and compared according to the years of diagnosis and birth. Results The RF of adenocarcinoma(ADC) increased from 21.96% to 43.36% and the RF of squamous cell carcinoma(SCC) decreased from 39.11% to 32.23% from 2000 to 2012 in the 15 427 male lung cancer patients included in this study(Z=17.909,P<0.0001; Z=-6.117,P<0.0001). The RF of ADC increased from 28.72% in 2000-2004,36.88% in 2005-2008 to 48.61% in 2009-2012 in patients born after 1960. The age-adjusted RF of ADC in 2007-2012 increased consistently in all the investigated areas. Conclusion The increased RF of ADC in male lung cancer patients highlights the need for further investigation of the etiologic factors of these tumors. Smoke-free policies rather than modifying tobacco products should be enforced.ZOU Xiao Nong LIN Dong Mei WAN Xia CHAO Ann FENG Qin Fu DAI Zhen YANG Gong Huan LV Ning 2014Biomedical and Environmental Sciences2014,27,1:19
3Roux-en-Y gastric bypass promotes expression of PDX-1 and regeneration of β-cells in Goto-Kakizaki rats显示文摘AIM:To study the effects of Roux-en-Y gastric bypass(RYGB) on the expression of pancreatic duodenal homeobox-1(PDX-1) and pancreatic β-cell regeneration/neogenesis,and their possible mechanisms in diabetics.METHODS:Three groups of randomly selected nonobese diabetic Goto-Kakizaki(GK) rats were subjected to RYGB,sham-RYGB and sham-operation(sham-op) surgery,respectively.The rats were euthanized at postoperative 1,2,4 and 12 wk.Their pancreases were resected and analyzed using reverse transcription polymerase chain reaction to detect the mRNA of PDX-1.Anti-PDX-1 immunohistochemical(IHC) staining and Western blotting were used to detect the protein of PDX-1.Double IHC staining of anti-Brdu and-insulin was performed to detect regenerated β-cells.The index of double Brdu and insulin positive cells was calculated.RESULTS:In comparison with sham-RYGB and sham-op groups,a significant increase in the expressions of PDX-1 mRNA in RYGB group was observed at all experimental time points(1 wk:0.378 ± 0.013 vs 0.120 ± 0.010,0.100 ± 0.010,F = 727.717,P < 0.001;2 wk:0.318 ± 0.013 vs 0.110 ± 0.010,0.143 ± 0.015,F = 301.509,P < 0.001;4 wk:0.172 ± 0.011 vs 0.107 ± 0.012,0.090 ± 0.010,F = 64.297,P < 0.001;12 wk:0.140 ± 0.007 vs 0.120 ± 0.010,0.097 ± 0.015,F = 16.392,P < 0.001);PDX-1 protein in RYGB group was also increased significantly(1 wk:0.61 ± 0.01 vs 0.21 ± 0.01,0.15 ± 0.01,F = 3031.127,P < 0.001;2 wk:0.55 ± 0.00 vs 0.15 ± 0.01,0.17 ± 0.01,F = 3426.455,P < 0.001;4 wk:0.39 ± 0.01 vs 0.18 ± 0.01,0.22 ± 0.01,F = 882.909,P < 0.001;12 wk:0.41 ± 0.01 vs 0.20 ± 0.01,0.18 ± 0.01,F = 515.833,P < 0.001).PDX-1 mRNA and PDX-1 protein production showed no statistical significance between the two sham groups.Many PDX-1 positive cells could be found in the pancreatic islets of the rats in RYGB group at all time points.In addition,the percentage of Brdu-insulin double staining positive cells was higher in RYGB group than in the other two groups(1 wk:0.22 ± 0.13 vs 0.03 ± 0.06,0.03 ± 0.06,P < 0.05;2 wk:0.28 ± 0.08 vs 0.00 ± 0.00,0.03 ± 0.06,P < 0.05;4 wk:0.24 ± 0.11 vs 0.07 ± 0.06,0.00 ± 0.00,P < 0.001;12 wk:0.20 ± 0.07 vs 0.03 ± 0.06,0.00 ± 0.00,P < 0.05).CONCLUSION:RYGB can increase the expression of pancreatic PDX-1 and induce the regeneration of β-cells in GK rats.The associated regeneration of islet cells may be a possible mechanism that how RYGB could improve type 2 diabetes mellitus.Zhen Li,Dong-Fei Li,Jing-Xing Dai,Yu Bai,Lin Yuan,Southern Medical University,Institute of Basic Medical Anatomy National Key Disciplines,Guangzhou 510515,Guangdong Province,China Hong-Ya Zhang,Lu-Xian Lv,Wen-Qiang Li,Second Affiliated Hospital,Xinxiang Medical College,Henan Province Key Laboratory of Biological Psychiatry,Xinxiang 453002,Henan Province,China Ou Sha,Department of Anatomy,Faculty of Medicine,Shenzhen University,Shenzhen 518060,Guangdong Province,China 2010World Journal of Gastroenterology2010,16,18:14

6Expressions of chromogranin A and cathepsin D in human primary hepatocellular carcinoma显示文摘AIM To determine the expression and clinicalsignificance of chromogranin A and cathepsin Din hepatocellular carcinoma(HCC).METHODS Double immunofluorescence stain-ing techniques combined with laser confocalscanning microscopy(LSCM)was used toinvestigate chromogranin A and cathepsin Dexpressions in 85 HCC patients.RESULTS Cathepsin D was expressed in :3normal liver tissues,while in HCC the stainingshowed regional variation and the fraction ofstrongly stained cells increased as the tumorsbecame less differentiated and usually clinicallymore malignant.Cells which showed strongpositivity for cathepsin D were present in 71/85(83.5%)cases.Strong expression of cathepsinD in cancer cells was related tohistopathological features.They were morecommon in grade 3-4(26/28,92.9%)and grade2(46/53,86.8%)tumors than in grade 1 tumors(1/4,25.0%)(P<0.01).No significantcorrelation was found between age andcathepsin D expression.In patients with positivecathepsin D reaction,the mean age was 52.1±2.8 years(range 32-68 years)and in the groupwith negative reaction,the mean age was 51.3±4.5 years(range 28-71 years).No obvious relationship was observed between CgAexpression in cancer cells and thehistopathological features.The CgA positiverate was 75.0%(3/4)in grade 1,71.7%(38/53)in grade 2,and 71.4%(20/28)in grade 3-4(P>0.05)tumors.The coexpression of CgA andcathepsin D was found by double labeledimmunofluorescence staining techniques.Theprocessing of cathepsin D was disturbed in HCCcells and accumulated in the cells.Cathepsin Dhad proteolytic activity and autocrine mitogeniceffect,suggesting their functions in invasion.These findings demonstrated that the expressionof cathepsin D in HCC had prognostic value.CONCLUSION Chromogranin A and cathepsin Dare expressed in a high proportion of HCC andthe existence of cathepsin D in HCC might berelated to processing of CgA.This is clearly asubject for further studies because of itspotential clinical applications.Xiao Feng Huang Chun Mei Wang Xiao Wen Dai Zhen Jiang Li Bo Rong Pan Li Bin Yu Bin Qian Li Fang 2000World Journal of Gastroenterology2000,6,5:12
7Chinese Hα Solar Explorer(CHASE)——a complementary space mission to the ASO-S显示文摘The Chinese HαSolar Explorer(CHASE)is designed to test a newly developed satellite platform and conduct solar observations.The scientific payload of the satellite is an Hαimaging spectrograph(HIS),which can,for the first time,acquire full-disk spectroscopic solar observations in the Hαwaveband.This paper briefly introduces CHASE/HIS including its scientific objectives,technical parameters,scientific application system,etc.The CHASE mission is scheduled to launch in 2021.It will complement the observations by on-orbit solar spacecraft(such as SDO,IRIS,STEREO and PSP),as well as future solar missions of the Solar Orbiter and Advanced Space-based Solar Observatory(ASO-S).Chuan Li Cheng Fang Zhen Li Ming-De Ding Peng-Fei Chen Zhe Chen Liang-Kui Lin Chang-Zheng Chen Chang-Ya Chen Hong-Jiang Tao Wei You Qi Hao Yu Dai Xin Cheng Yang Guo Jie Hong Min-Jie An Wei-Qiang Cheng Jian-Xin Chen Wei Wang Wei Zhang 2019Research in Astronomy and Astrophysics2019,19,11:12
8Biological imaging without autofluorescence in the second near-infrared region显示文摘Fluorescence imaging is capable of acquiring anatomical and functional infor- mation with high spatial and temporal resolution. This imaging technique has been indispensable in biological research and disease detection/diagnosis. Imaging in the visible and to a lesser degree, in the near-infrared (NIR) regions below 900 nm, suffers from autofluorescence arising from endogenous fluorescent molecules in biological tissues. This autofluorescence interferes with fluorescent molecules of interest, causing a high background and low detection sensitivity. Here, we report that fluorescence imaging in the 1,500-1,700-nm region (termed "NIR-IIb") under 808-nm excitation results in nearly zero tissue autofluorescence, allowing for background-free imaging of fluorescent species in otherwise notoriously autofluorescent biological tissues, including liver. Imaging of the intrinsic fluorescence of individual fluorophores, such as a single carbon nanotube, can be readily achieved with high sensitivity and without autofluorescence background in mouse liver within the 1,500-1,700-nm wavelength region.Shuo Diao Guosong Hong Alexander L.

13Synthesis of a Novel Core-shell Type Acrylic-polyurethane Hybrid Emulsion Containing Siloxane and Fluorine as well as Water and the Oil Resistances of Cured Film显示文摘Siliconated polyurethane (Si-PU) was synthesized using isophorone diisocyanate (IPDI), hydroxybutyl-terminated polydimethylsiloxane (PDMS), polytetramethylene ether glycol (PTMG), polypropylene glycol (PPG), 1,6-hexanediol (HDO), dimethylol propionic acid (DMPA) and triethylamine (TEA). Based on butyl acrylate (BA), 2, 2, 2-trifluoroethylmethacrylate (TFEMA) and Si-PU as a seed emulsion, a novel core-shell type acrylic-polyurethane hybrid emulsion, containing siloxane and fluorine (F-Si-PU), was prepared by seeded emulsion polymerization. The contents of siloxane and fluorine were determined according to the feed ratio. Fourier transform infrared spectroscopy (FTIR) was used to identify the chain structures of Si-PU and F-Si-PU. Investigation of transmission electron microscopy (TEM) confirmed the core-shell structure of F-Si-PU emulsion. Measurement results of water contact angle and the swelling ratio in water and n-octane for cured film showed that the water and the oil resistances for F-Si-PU had been significantly improved at a suitable content of fluorine and siloxane.Jing CHAO Xing Yuan ZHANG Jia Bing DAI Zhen GE Lin Lin FENG 2006Chinese Chemical Letters2006,17,8:7
