5Usefulness 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 2015Chinese Journal of Cancer Research2015,27,3:10
6The role of dynamic transport in the formation of the inverted charge structure in a simulated hailstorm显示文摘The inverted charge structure formation of a hailstorm was investigated using the Advanced Weather Research and Forecasting(WRF-ARW) model coupled with electrification and discharge schemes. Different processes may be responsible for inverted charge structure in different storms and regions. A dynamical-derived mechanism of inverted charge structure formation was confirmed by the numerical model: the inverted structure was formed by strong updraft and downdraft under normal-polarity charging conditions such that the graupel charged negatively in the main charging region in the middle-upper level of the cloud. The simulation results showed the storm presented a normal charge structure before and after hail-fall; while during the hail-fall stage, it showed an inverted charge structure—negative charge region in the upper level of the cloud and a positive charge region in the middle level of the cloud—appearing at the front edge near the strong updraft in the hailstorm. The charging processes between the two particles mainly occurred at the top of the cloud, where the graupel charged negatively and ice crystals positively due to the strong updraft. When the updraft air reached the top of the storm, it would spread to the rear and front. The light ice crystals were transported backward and forward more easily. Meanwhile, the positively charged ice crystals were transported downward by the frontal subsidence, and then a positive charge region formed between the ?10 and ?25°C levels. Subsequently, a negative charge region materialized in the upper level of the cloud, and the inverted charge structure formed.XU Liang Tao ZHANG Yi Jun LIU Heng Yi ZHENG Dong WANG Fei 2016Science China Earth Sciences2016,59,7:8

14Molecular Spectrum ofα-andβ-Thalassemia among Young Individuals of Marriageable Age in Guangdong Province,China显示文摘Thalassemia is a group of genetically heterogeneous diseases characterized by hemolytic anemia.To investigate molecular characteristics ofα-andβ-thalassemia among young individuals of marriageable age in Guangdong Province,24,788 subjects with suspected thalassemia were genetically tested forα-andβ-thalassemia by GapPCR and reverse dot blot during 2018–2019.For suspected rare thalassemia cases,DNA sequencing was performed to identify rare and unknown thalassemia gene mutations.A total of 14,346 thalassemia carriers were detected,including 7,556 cases ofα-thalassemia with 25 genotypes and 8α-gene mutations identified,5,860 cases ofβ-thalassemia with 18 genotypes and 18β-gene mutations identified,and 930 cases of compoundα/β-thalassemia.Among them,the frequency of--SEA deletion was the highest inα-thalassemia(66.01%),followed by-α3.7(17.98%)and-α.24(8.22%),and the frequency of CD41-42(-TCTT)mutation was the highest inβ-thalassemia(38.38%),followed by IVS-II-654(C>T)(25.67%),-28(A>G)(15.76%),and CD17(10.01%).In addition,5 rare mutations(--THAI and HKαα,CD113,-90,and CD56)were found in the study population.Our results revealed molecular epidemiological background ofα-andβ-thalassemia in Guangdong Province,which can support optimization of thalassemia prevention and control strategies.We demonstrated that thalassemia is heterogeneous with significant geographical differences and population specificity.ZHOU Bing Yi& WANG Yong Xia XU Shan Shan GU Heng LI Ming Zhen 2021Biomedical and Environmental Sciences2021,34,10:4
15Effect of thermal exposure on the stress-rupture life and microstructure of a low Re-containing single crystal alloy显示文摘In this paper, the stress-rupture tests of a low Re-containing single crystal alloy IC21 before and after thermal exposure at 1100 ℃for various periods of time were conducted under the test condition of 1100 ℃/137 MPa, and the microstructure of the tested specimens was characterized by SEM and TEM. The experimental results showed that the stress rupture life of this alloy was over 150 h after the standard heat treatment of1320 ℃, 10 h/AC t 870, 32 h/AC, however the stress rupture life decreased with the increase of exposure time due to the microstructure degradation. The TEM analysis revealed that the interface mismatch dislocation networks were well established. It was observed that these mismatch networks could form at 1100 ℃ even after thermal exposure for 1 h without the external stress, which is quite different from that in the traditional single crystal superalloys.Heng Zhang Yunfei Liang Yi Ru Shusuo Li Jian Zhou Shengkai Gong 2015Progress in Natural Science:Materials International2015,25,1:4
16Protein Array-based Approaches for Biomarker Discovery in Cancer显示文摘Biomarkers are deemed to be potential tools in early diagnosis, therapeutic monitoring,and prognosis evaluation for cancer, with simplicity as well as economic advantages compared with computed tomography and biopsy. However, most of the current cancer biomarkers present insufficient sensitivity as well as specificity. Therefore, there is urgent requirement for the discovery of biomarkers for cancer. As one of the most exciting emerging technologies, protein array provides a versatile and robust platform in cancer proteomics research because it shows tremendous advantages of miniaturized features, high throughput, and sensitive detections in last decades. Here, we will present a relatively complete picture on the characteristics and advance of different types of protein arrays in application for biomarker discovery in cancer, and give the future perspectives in this area of research.Yi Huang Heng Zhu 2017Genomics, Proteomics & Bioinformatics2017,15,2:4
17Evaluation 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 2019Chinese Journal of Cancer Research2019,31,4:4
18The FAST Galactic Plane Pulsar Snapshot survey:I.Project design and pulsar discoveries显示文摘Discovery of pulsars is one of the main goals for large radio telescopes.The Five-hundredmeter Aperture Spherical radio Telescope(FAST),that incorporates an L-band 19-beam receiver with a system temperature of about 20 K,is the most sensitive radio telescope utilized for discovering pulsars.We designed the snapshot observation mode for a FAST key science project,the Galactic Plane Pulsar Snapshot(GPPS)survey,in which every four nearby pointings can observe a cover of a sky patch of 0.1575 square degrees through beam-switching of the L-band 19-beam receiver.The integration time for each pointing is 300 seconds so that the GPPS observations for a cover can be made in 21 minutes.The goal of the GPPS survey is to discover pulsars within the Galactic latitude of±10∘from the Galactic plane,and the highest priority is given to the inner Galaxy within±5∘.Up to now,the GPPS survey has discovered 201 pulsars,including currently the faintest pulsars which cannot be detected by other telescopes,pulsars with extremely high dispersion measures(DMs)which challenge the currently widely used models for the Galactic electron density distribution,pulsars coincident with supernova remnants,40 millisecond pulsars,16 binary pulsars,some nulling and mode-changing pulsars and rotating radio transients(RRATs).The follow-up observations for confirmation of new pulsars have polarization-signals recorded for polarization profiles of the pulsars.Re-detection of previously known pulsars in the survey data also leads to significant improvements in parameters for 64 pulsars.The GPPS survey discoveries are published and will be updated at http://gffzz656c80eee53645cchp0qvooxv5ouq6nfp.ffgz.tsg.suse.edu.cn/GPPS/.J.L.Han Chen Wang P.F.Wang Tao Wang D.J.Zhou Jing-Hai Sun Yi Yan Wei-Qi Su Wei-Cong Jing Xue Chen X.Y.Gao Li-Gang Hou Jun Xu K.J.Lee Na Wang Peng Jiang Ren-Xin Xu Jun Yan Heng-Qian Gan Xin Guan Wen-Jun Huang Jin-Chen Jiang Hui Li Yun-Peng Men Chun Sun Bo-Jun Wang H.G.Wang Shuang-Qiang Wang Jin-Tao Xie Heng Xu Rui Yao Xiao-Peng You D.J.Yu Jian-Ping Yuan Rai Yuen Chun-Feng Zhang Yan Zhu 2021Research in Astronomy and Astrophysics2021,21,5:4
