| 1 | Prognostic factors of refractory NSCLC patients receiving anlotinib hydrochloride as the third-or further-line treatment显示文摘Objective:Anlotinib hydrochloride is a multitarget tyrosine kinase inhibitor that targets vascular endothelial growth factor receptor,fibroblast growth factor receptor,platelet-derived growth factor receptor,c-Kit,and c-MET;therefore,it exhibits both antitumor and anti-angiogenetic activities.A phase III trial has shown that anlotinib improved progression-free survival(PFS)and overall survival(OS)in patients with advanced non-small cell lung cancer(NSCLC),who presented with progressive disease or intolerance after standard chemotherapy.This study aimed to analyze the characteristics of patients receiving anlotinib treatment to determine the dominant populations who are fit for the treatment.Methods:Data were collected from March 2015 to January 2017 from a randomized,double-blind,placebo-controlled,multicenter,phase III trial of anlotinib(ALTER0303).A total of 437 patients were enrolled and randomly allocated(2:1)to the anlotinib and placebo groups.Kaplan–Meier analysis and log-rank test were performed to compare PFS and OS.Cox proportional hazards model was adopted for multivariate prognostic analysis.Results:Multivariate analysis indicated that high post-therapeutic peripheral blood granulocyte/lymphocyte ratio and elevated alkaline phosphatase levels were independent risk factors for PFS.Meanwhile,elevated thyroid-stimulating hormone,blood glucose,and triglyceride levels;hypertension;and hand–foot syndrome were independent protective factors of PFS.High posttherapeutic peripheral blood granulocyte/lymphocyte ratio,an Eastern Cooperative Oncology Group(ECOG)score≥2,and the sum of the maximal target lesion length at baseline were independent risk factors of OS,and hypertriglyceridemia was an independent protective factor of OS.Conclusions:This study preliminarily explored the possible factors that affected PFS and OS after anlotinib treatment in patients with advanced refractory NSCLC,and the baseline characteristics of the therapeutically dominant populations were then identified. | Jing Wang Yizhuo Zhao Qiming Wang Li Zhang Jianhua Shi Zhehai Wang Ying Cheng Jianxing He Yuankai Shi Hao Yu Yang Zhao Weiqiang Chen Yi Luo Xiuwen Wang Kejun Nan Faguang Jin Jian Dong Baolan Li Zhujun Liu Baohui Han Kai Li | 2018 | Cancer Biology & Medicine2018，15，4： | 46 |
| 2 | The 1997-1998 warm event in the South China Sea显示文摘A strong warm event happens during spring 1997 to spring 1999 in the South China Sea. Its intensity and duration show that it is the strongest event on the record over the past decades. It also corresponds with the severe flood over the valley of the Yangtze River and a couple of marine environmental events. This note addressed the evolution process by using several data sets, such as sea surface temperature, height and wind stress in addition to subsurface temperature. The onset of the warm event almost tele-connects with the El Nino event in the tropical Pacific Ocean. Summer monsoon is stronger and winter monsoon is weaker in 1997 so that there are persistent westerly anomalies in the South China Sea. During the development phase, the warm advection caused by southerly anomalies is the major factor while the adjustment of the thermocline is not obvious. Subsequently, the southerly anomalies decay and even northerly anomalies appear in the summer of 1998 resulting from the weaker than normal summer | WANG Dongxiao XIE Qiang DU Yan WANG Weiqiang CHEN Ju | 2002 | Chinese Science Bulletin2002，47，14： | 24 |

| 6 | Safety and feasibility of video-assisted thoracoscopic surgery for stage IIIA lung cancer显示文摘Objective: The current study was prospectively designed to explore the application of video-assisted thoracoscopic surgery(VATS) radical treatment for patients with stage IIIA lung cancer, with the primary endpoints being the safety and feasibility of this operation and the second endpoints being the survival and complications after the surgery.Methods: A total of 51 patients with radiologically or mediastinoscopically confirmed stage IIIA lung cancer underwent VATS radical treatment, during which the standard pulmonary lobectomy and mediastinal lymph node dissection were performed after pre-operative assessment. The operative time, intraoperative blood loss/complications, postoperative recovery, postoperative complications, and lymph node dissection were recorded and analyzed. This study was regarded as successful if the surgical success rate reached 90% or higher.Results: A total of 51 patients with non-small cell lung cancer(NSCLC) were enrolled in this study from March 2009 to February 2010. The median post-operative follow-up duration was 50.5 months. Of these 51 patients, 41(80.4%) had N2 lymph node metastases. All patients underwent the thoracoscopic surgeries, among whom 50(98%) received pulmonary lobectomy and mediastinal lymph node dissection completely under the thoracoscope, 6 had their incisions extended to about 6 cm due to larger tumor sizes, and 1 had his surgery performed using a 12 cm small incision for handling the adhesions between lymph nodes and blood vessels. No patient was converted to conventional open thoracotomy. No perioperative death was noted. One patient received a second surgery on the second post-operative day due to large drainage(>1,000 mL), and the postoperative recovery was satisfactory. Up to 45 patients(88.2%) did not suffer from any perioperative complication, and 6(11.8%) experienced one or more complications.Conclusions: VATS radical treatment is a safe and feasible treatment for stage IIIA lung cancer. | Wenlong Shao Jun Liu Wehua Liang Hanzhang Chen Shuben Li Weiqiang Yin Xin Zhang Jianxing He | 2014 | Chinese Journal of Cancer Research2014，26，4： | 12 |
| 7 | Porous LiFePO_(4)/NiP Composite Nanospheres as the Cathode Materials in Rechargeable Lithium Ion Batteries显示文摘We report the synthesis of porous LiFePO4/NiP composite nanospheres and their application in rechargeable lithium-ion batteries.A simple one-step spraying technique was developed to prepare LiFePO_(4)/NiP composite nanospheres with an electrical conductivity 10^(3)-10^(4) times that of bulk particles of LiFePO_(4).Electrochemical measurements show that LiFePO_(4) nanospheres with a uniform loading of 0.86 wt%1.50 wt%NiP exhibit high discharge capacity,good cycling reversibility,and low apparent activation energies.The superior electrode performance of the as-prepared composite nanospheres results from the greatly enhanced electrical conductivity and porous structure of the materials. | Chunsheng Li Shaoyan Zhang Fangyi Cheng Weiqiang Ji Jun Chen | 2008 | Nano Research2008，1，3： | 12 |

| 9 | Long-distance ranging with high precision using a soliton microcomb显示文摘Laser-based light detection and ranging(lidar)plays a significant role in both scientific and industrial areas.However,it is difficult for existing lidars to achieve high speed,high precision,and long distance simultaneously.Here,we demonstrate a high-performance lidar based on a chip-scaled soliton microcomb(SMC)that can realize all three specialties simultaneously.Aided by the excellent properties of ultrahigh repetition rate and the smooth envelope of the SMC,traditional optical frequency comb(OFC)-based dispersive interferometry is heavily improved and the measuring dead zone induced by the mismatch between the repetition rate of the OFC and resolution of the optical spectrum analyzer is totally eliminated.Combined with an auxiliary dual-frequency phase-modulated laser range finder,the none-dead-zone measurable range ambiguity is extended up to 1500 m.The proposed SMC lidar is experimentally implemented in both indoor and outdoor environment.In the outdoor baseline field,real-time,high-speed(up to 35 k Hz)measurement of a long distance of^1179 m is achieved with a minimum Allan deviation of 5.6μm at an average time of 0.2 ms(27 nm at an average time of 1.8 s after high-pass filtering).The present SMC lidar approaches a compact,fast,high-precision,and none-dead zone long-distance ranging system,aimed at emerging applications of frontier basic scientific research and advances in industrial manufacturing. | JINDONG WANG ZHIZHOU LU WEIQIANG WANG FUMIN ZHANG JIAWEI CHEN YANG WANG JIHUI ZHENG SAI T.CHU WEI ZHAO BRENT E.LITTLE XINGHUA QU WENFU ZHANG | 2020 | Photonics Research2020，8，12： | 8 |
| 10 | Aboveground biomass and corresponding carbon sequestration ability of four major forest types in south China显示文摘We estimated aboveground biomass carbon (TABC) and net carbon accumulation rates (TNEP) for trees in four major forest types based on national forest inventory data collected in 1994-1998 and 1999-2003. The four types were Pinus massoniana forest, Cunninghamia lanceolata forest, hard broad-leaved evergreen forest and soft broad-leaved evergreen forest. We analyzed variations in TABC and TNEP for five stand ages (initiation, young, medium, mature and old). In both time periods, estimated TABC in all four forest types increased consistently with forest stand age and the oldest stage had the largest TABC compared with other stages. Broad-leaved forests (hard and soft) had higher TABC than needle-leaved forests (Pinus massoniana and Cunninghamia lanceolata) for each of the five age stages. The difference of TABC between broad-leaved and needle-leaved forests increased with forest stand age. Comparison of estimated TNEP by age category indicated TNEP increased from the initiation stage to the young stage, and then decreased from the mature stage to old stage in all four forest types. TNEP for any particular stage depended on the forest type; for instance, broad-leaved forests at both the mature and old stages had greater TNEP than in needle-leaved forests. A logistic curve was applied to fit the relationship between TABC and forest stand age. In each period, correlations in all four forest types were all statistically significant (P < 0.01) with R2 > 0.95. TABC was therefore predicted by these regression functions from 2000 to 2050 and the mean TNEP during the predicted period was estimated to be about 41.14, 31.53, 75.50 and 75.68 gCm-2a-1 in Pinus massoniana forest, Cunninghamia lanceolata forest, hard broad-leaved forest and soft broad-leaved forest, respectively. Results from both forest inventory and regression prediction suggest broad-leaved forests are greater carbon sinks, and hence have greater carbon sequestration ability especially in the mature and old stages when compared to needle-leaved forests. Broad-leaved forests should have high levels of carbon sequestration when compared with needle-leaved forests in south China. | CHEN QingQing XU WeiQiang LI ShengGong FU ShengLei YAN JunHua | 2013 | Chinese Science Bulletin2013，58，13： | 8 |

| 13 | The Chinese Hα Solar Explorer(CHASE) mission: An overview显示文摘The Chinese Hα Solar Explorer(CHASE), dubbed “Xihe”—Goddess of the Sun, was launched on October 14, 2021 as the first solar space mission of China National Space Administration(CNSA). The CHASE mission is designed to test a newly developed satellite platform and to acquire the spectroscopic observations in the Hα waveband. The Hα Imaging Spectrograph(HIS)is the scientific payload of the CHASE satellite. It consists of two observational modes: raster scanning mode and continuum imaging mode. The raster scanning mode obtains full-Sun or region-of-interest spectral images from 6559.7 to 6565.9 ? and from 6567.8 to 6570.6 ? with 0.024 ? pixel spectral resolution and 1 min temporal resolution. The continuum imaging mode obtains photospheric images in continuum around 6689 ? with the full width at half maximum of 13.4 ?. The CHASE mission will advance our understanding of the dynamics of solar activity in the photosphere and chromosphere. In this paper, we present an overview of the CHASE mission including the scientific objectives, HIS instrument overview, data calibration flow, and first results of on-orbit observations. | Chuan Li Cheng Fang Zhen Li MingDe Ding PengFei Chen Ye Qiu Wei You Yuan Yuan MinJie An HongJiang Tao XianSheng Li Zhe Chen Qiang Liu Gui Mei Liang Yang Wei Zhang WeiQiang Cheng JianXin Chen ChangYa Chen Qiang Gu QingLong Huang MingXing Liu ChengShan Han HongWei Xin ChangZheng Chen YiWei Ni WenBo Wang ShiHao Rao HaiTang Li Xi Lu Wei Wang Jun Lin YiXian Jiang LingJie Meng Jian Zhao | 2022 | Science China(Physics,Mechanics & Astronomy)2022，65，8： | 7 |

| 15 | Long-term survival outcomes of video-assisted thoracic surgery for patients with non-small cell lung cancer显示文摘Background: Video-assisted thoracic surgery(VATS) has been shown to be a safe alternative to conventional thoracotomy for patients with non-small cell lung cancer(NSCLC). However, popularization of this relatively novel technique has been slow, partly due to concerns about its long-term outcomes. The present study aimed to evaluate the long-term survival outcomes of patients with NSCLC after VATS, and to determine the significant prognostic factors on overall survival.Methods: Consecutive patients diagnosed with NSCLC referred to one institution for VATS were identified from a central database. Patients were treated by either complete-VATS or assisted-VATS, as described in previous studies. A number of baseline patient characteristics, clinicopathologic data and treatment-related factors were analyzed as potential prognostic factors on overall survival.Results: Between January 2000 and December 2007, 1,139 patients with NSCLC who underwent VATS and fulfilled a set of predetermined inclusion criteria were included for analysis. The median age of the entire group was 60 years, with 791 male patients(69%). The median 5-year overall survival for Stage I, II, III and IV disease according to the recently updated TNM classification system were 72.2%, 47.5%, 29.8% and 28.6%, respectively. Female gender, TNM stage, pT status, and type of resection were found to be significant prognostic factors on multivariate analysis.Conclusions: VATS offers a viable alternative to conventional open thoracotomy for selected patients with clinically resectable NSCLC. | Wenlong Shao Xinguo Xiong Hanzhang Chen Jun Liu Weiqiang Yin Shuben Li Xin Xu Xin Zhang Jianxing He | 2014 | Chinese Journal of Cancer Research2014，26，4： | 5 |

| 17 | Multi-scale variability of the tropical Indian Ocean circulation system revealed by recent observations显示文摘The tropical Indian Ocean circulation system includes the equatorial and near-equatorial circulations, the marginal sea circulation, and eddies. The dynamic processes of these circulation systems show significant multi-scale variability associated with the Indian Monsoon and the Indian Ocean dipole. This paper summarizes the research progress over recent years on the tropical Indian Ocean circulation system based on the large-scale hydrological observations and numerical simulations by the South China Sea Institute of Oceanology(SCSIO), Chinese Academy of Sciences. Results show that:(1) the wind-driven Kelvin and Rossby waves and eastern boundary-reflected Rossby waves regulate the formation and evolution of the Equatorial Undercurrent and the Equatorial Intermediate Current;(2) the equatorial wind-driven dynamics are the main factor controlling the inter-annual variability of the thermocline in the eastern Indian Ocean upwelling;(3) the equatorial waves transport large amounts of energy into the Bay of Bengal in forms of coastal Kelvin and reflected free Rossby waves. Several unresolved issues within the tropical Indian Ocean are discussed:(i) the potential effects of the momentum balance and the basin resonance on the variability of the equatorial circulation system, and(ii) the potential contribution of wind-driven dynamics to the life cycle of the eastern Indian Ocean upwelling. This paper also briefly introduces the international Indian Ocean investigation project of the SCSIO, which will advance the study of the multi-scale variability of the tropical Indian Ocean circulation system, and provide a theoretical and data basis to support marine environmental security for the countries around the Maritime Silk Road. | Ke HUANG Dongxiao WANG Weiqiang WANG Qiang XIE Ju CHEN Lingfang CHEN Gengxin CHEN | 2018 | Science China Earth Sciences2018，61，6： | 4 |

| 19 | Levitated-body ultra-high pointing accuracy and stability satellite platform of the CHASE mission显示文摘The CHASE satellite is designed based on the novel ultra-high pointing accuracy and stability levitated-body satellite platform,which breaks the traditional idea of rigidly connecting the satellite platform and payload. When operating in orbit, the platform and payload are non-connected and spatially levitated. By separately arranging the “noisy” and “quiet” devices, the complicated influence of platform vibration on the payload pointing direction is effectively avoided. Using the novel master-slave collaborative control method, the pointing accuracy and stability of the payload are improved considerably. In this paper, the basic principles, overall scheme, control method, and engineering implementation of a levitated-body satellite platform are discussed.Combined with the CHASE mission in-orbit data, the actual attitude pointing precision and stability of a levitated-body satellite platform are analyzed and evaluated. | Wei Zhang WeiQiang Cheng Wei You Xiao Chen Jian Zhang Chuan Li Cheng Fang | 2022 | Science China(Physics,Mechanics & Astronomy)2022，65，8： | 3 |
| 20 | True random coded photon counting Lidar显示文摘A true random coded photon counting Lidar system is proposed in this paper,in which a single photon detector acts as the true random sequence signal generator instead of the traditional function generator.Compared with the traditional pseudo-random coded method,the true random coded method not only improves the anti-crosstalk capability of the system,but more importantly,it effectively overcomes the adverse effect of the detector’s dead time on the ranging performance.The experiment results show that the ranging performance of the true random coded method is obviously better than that of the pseudo-random coded method.As a result,a three-dimensional scanning imaging of a model car is completed by the true random coded method. | Bo Liu Yang Yu Zhen Chen Weiqiang Han | 2020 | Opto-Electronic Advances2020，3，2： | 3 |
