| 1 | Safety,tolerability,and pharmacokinetics of BAT8001 in patients with HER2-positive breast cancer:An open-label,dose-escalation,phase I study显示文摘Background:The introductions of anti-human epidermal growth factor receptor-2(HER2)agents have significantly improved the treatment outcome of patients with HER2-positive breast cancer.BAT8001 is a novel antibodydrug conjugate targeting human epidermal growth factor receptor-2(HER2)-expressing cells composed of a trastuzumab biosimilar linked to the drug-linker Batansine.This dose-escalation,phase I study was designed to assess the safety,tolerability,pharmacokinetics,and preliminary anti-tumor activity of BAT8001 in patients with HER2-positive locally advanced or metastatic breast cancer.Methods:This trial was conducted in subjects with histologically confirmed HER2-positive breast cancer(having evaluable lesions and an Eastern Cooperative Oncology Group performance status of 0 or 1)using a 3+3 design of escalating BAT8001 doses.Patients received BAT8001 intravenously in a 21-day cycle,with dose escalation in 5 cohorts:1.2,2.4,3.6,4.8,and 6.0 mg/kg.The primary objective was to evaluate the safety and tolerability of BAT8001.Preliminary activity of BAT8001 was also assessed as a secondary objective.Results:Between March 2017 to May 2018,29 HER2-positive breast cancer patients were enrolled.The observed dose-limiting toxicities were grade 4 thrombocytopenia and grade 3 elevated transaminase.The maximum tolerated dose was determined to be 3.6 mg/kg.Grade 3 or greater adverse events(AEs)occurred in 14(48.3%)of 29 patients,including thrombocytopenia in 12(41.4%)patients,aspartate aminotransferase increased in 4(13.8%)patients,γ-glutamyl transferase increased in 2(6.9%)patients,alanine aminotransferase increased in 2(6.9%)patients,diarrhea in 2(6.9%)patients.Objective response was observed in 12(41.4%,95%confidence interval[CI]=23.5%-61.1%)and disease control(including patients achieving objective response and stable disease)was observed in 24(82.8%,95%CI=64.2%-94.2%)patients.Conclusions:BAT8001 demonstrated favorable safety profiles,with promising anti-tumor activity in patients with HER2-positive locally advanced or metastatic breast cancer.BAT8001 has the potential to provide a new therapeutic option in patients with metastatic HER2-positive breast cancer. | Ruoxi Hong Wen Xia Liye Wang Kaping Lee Qianyi Lu Kuikui Jiang Shengfeng Li Jinquan Yu Jin Wei Weijia Tang Danyang Zhou Xin An Jiajia Huang Cong Xue Xiwen Bi Yanxia Shi Zhongyu Yuan Fei Xu Shusen Wang | 2021 | Cancer Communications2021，41，2： | 2 |
| 2 | Multifunctional semitransparent organic solar cells with excellent infrared photon rejection显示文摘Semitransparent organic solar cells(ST-OSCs)have the potentials to open promising applications that differ from those of conventional inorganic ones,such as see-through power windows with both energy generation and heat insulation functions.However,to achieve so,there remain significant challenges,especially for balancing critical parameters,such as power conversion efficiency(PCE),average visible transparency(AVT)and low energy infrared photon radiation rejection(IRR)to realize the full potentials of ST-OSCs.Herein,we demonstrate the new design of ST-OSCs through the rational integration of organic materials,transparent electrode and infrared photon reflector in one device.With the assistance of optical simulation,new ST-OSCs with precise layout exhibit state-of-art performance,with near 30%AVT and PCE of 7.3%,as well as an excellent IRR of over 93%(780-2500 nm),representing one of best multifunctional ST-OSCs with promising perspective for window application. | Xue Li Ruoxi Xia Kangrong Yan Hin-Lap Yip Hongzheng Chen Chang-Zhi Li | 2020 | Chinese Chemical Letters2020，31，6： | 1 |
| 3 | Simulation of EOM-based frequency-chirped laser slowing of MgF radicals显示文摘Here we propose a scheme to slow MgF molecules by using EOM-based frequency-chirped radiation pressure slowing.The scheme well addresses the need for a rapid chirp rate while light molecules are being laser slowed,whose scattering rate and recoil velocity are large.Two EOMs are used to compensate the rapidly changing Doppler shifts arised from the movement of molecules,and to cover the hyperfine energy structure of MgF,respectively.Based the scattering rate maps calculated from an optical Bloch equation model,individual molecule trajectories are simulated by using a semi-classical three-dimensional Monte Carlo approach.We show how the modulation configuration of EOM and the magnetic field influence the slowing results.The study shows that a cryogenic buffer gas-cooled MgF beam source is possible to be slowed down with a number of∼1.4×10^(6)–10^(7),and the final forward speed peaks at∼10 m/s near the capture velocity of a molecular MOT. | Kang Yan RuoXi Gu Di Wu Jin Wei Yong Xia Jianping Yin | 2022 | Frontiers of physics2022，17，4： | 1 |
| 4 | Nail pigmentation induced by chemotherapy:an observational study of patients with early-stage breast cancer显示文摘Purpose:Chemotherapy-induced nail pigmentation is a common adverse efect,but prospective studies focussing on its onset,recovery,and severity are few.We aim to evaluate the pattern of chemotherapy-induced nail pigmentation in early-stage breast cancer patients by calculating the comprehensive score based on hyperpigmentation area and color depth of the nail plate.Methods:This prospective,observational study was conducted between February 2019 and December 2019.Early-stage breast cancer patients scheduled to receive anthracyclines combined with cyclophosphamide or taxanecontaining regimens were enrolled.The clinicopathologic characteristics and treatment protocols were collected.The onset,patterns,and duration of nail changes were photographed and recorded regularly.Results:A total of 90 patients were enrolled.The most common nail change was nail pigmentation(n=81,90.0%),followed by onycholysis(n=39,43.3%),Beau’s lines(n=19,21.1%),Mees’lines(n=16,17.8%),Muehrcke’s lines(n=7,7.8%),and hemorrhage(n=1,1.1%).Forty-four(48.9%)patients developed severe nail pigmentation.The median onset time of nail pigmentation was 37 days after the initiation of chemotherapy.At the latest follow-up,55(67.9%)patients achieved remission of melanonychia with the median recovery time of 118 days.The median duration of nail pigmentation was 214 days.Conclusion:Our study revealed the specifc pattern of chemotherapy-induced nail pigmentation,which onsets early and recovers slowly with a high incidence of severe nail pigmentation,in early-stage breast cancer patients.The results provide reference for further intervention studies.Trial Registration:ClinicalTrials.gov Identifer:NCT04215744.Registered 30 December 2019—Retrospectively registered. | Kuikui Jiang Simei Shi Qiulian Lin Peng Sun Luan Zhang Zhongyu Yuan Ruoxi Hong Yanxia Shi Xia Liu Jingmin Zhang Jiajia Huang Xiwen Bi Wen Xia Qianyi Lu Qiufan Zheng Shusen Wang Fei Xu | 2022 | Holistic Integrative Oncology2022，1，1： | 0 |
| 5 | Metronomic chemotherapy of cyclophosphamide plus methotrexate for advanced breast cancer:Real-world data analyses and experience of one center显示文摘Background:Real-world data of the CM regimen[cyclophosphamide(CTX)plus methotrexate(MTX)]in metronomic pattern for advanced breast cancer is limited to small-sample or retrospective studies.This study was aimed to determine the effectiveness and safety of CM regimen in treating advanced breast cancer and to identify which patients are most likely to benefit from metronomic CM regimen.Methods:Patients with advanced breast cancer who received the metronomic CM regimen at least once between January 2009 and February 2019 in Sun Yat-sen University Cancer Center were included.Clinicopathological characteristics were collected.Overall survival(OS)and progression-free survival(PFS)were assessed using Kaplan-Meier estimates.Characteristics between patients with PFS<6 months and≥6 months were compared using the Chi-square test.Univariate and multivariate Cox regression model was used to estimate the prognostic factors for PFS and OS.Results:A total of 186 patients were included.The median age and follow-up were 49 years and 13.3 months,respectively.Over 50%of the patients were estrogen receptor/progesterone receptor-positive,and 60.8%had been heavily treated(≥3 lines).The objective response rate was 3.8%,the disease control rate at 12 weeks was 41.4%,and the clinical benefit rate at 24 weeks was 31.2%(58/186).The median PFS was 4.0 months[95%confidence interval(CI):3.6-4.7 months],the median duration of clinical benefit was 9.5 months(95%CI:8.2-10.8 months),and the median OS was 26.8 months(95%CI:20.9-37.7 months).Multivariate analysis for PFS revealed the CM regimen as maintenance therapy and no liver metastasis as favorable prognostic factors.Furthermore,patients without liver metastasis were more likely to have a PFS over 6 months than those with liver involvement(P=0.022).Liver,lymph node,and brain metastases were unfavorable prognostic factors for OS.The CM regimen was well-tolerated without newly reported adverse events.Conclusions:The CM regimen was effective in selected patients.In clinical practice,it would be better used as maintenance therapy and in patients without liver metastasis.Further follow-up investigation should be performed to examine its effect when used in combination with other treatments and determine predictive biomarkers. | Qianyi Lu Kaping Lee Fei Xu Wen Xia Qiufan Zheng Ruoxi Hong Kuikui Jiang Qinglian Zhai Yuan Li Yanxia Shi Zhongyu Yuan Shusen Wang | 2020 | Cancer Communications2020，40，5： | 0 |
| 6 | Handwashing quality assessment via deep learning:a modelling study for monitoring compliance and standards in hospitals and communities显示文摘Background Hand hygiene can be a simple,inexpensive,and effective method for preventing the spread of infectious diseases.However,a reliable and consistent method for monitoring adherence to the guidelines within and outside healthcare settings is challenging.The aim of this study was to provide an approach for monitoring handwashing compliance and quality in hospitals and communities.Methods We proposed a deep learning algorithm comprising three-dimensional convolutional neural networks(3D CNNs)and used 230 standard handwashing videos recorded by healthcare professionals in the hospital or at home for training and internal validation.An assessment scheme with a probability smoothing method was also proposed to optimize the neural network’s output to identify the handwashing steps,measure the exact duration,and grade the standard level of recognized steps.Twenty-two videos by healthcare professionals in another hospital and 28 videos recorded by civilians in the community were used for external validation.Results Using a deep learning algorithm and an assessment scheme,combined with a probability smoothing method,each handwashing step was recognized(ACC ranged from 90.64%to 98.87%in the hospital and from 87.39%to 96.71%in the community).An assessment scheme measured each step’s exact duration,and the intraclass correlation coefficients were 0.98(95%CI:0.97-0.98)and 0.91(95%CI:0.88-0.93)for the total video duration in the hospital and community,respectively.Furthermore,the system assessed the quality of handwashing,similar to the expert panel(kappa=0.79 in the hospital;kappa=0.65 in the community).Conclusions This work developed an algorithm to directly assess handwashing compliance and quality from videos,which is promising for application in healthcare settings and communities to reduce pathogen transmis-sion. | Ting Wang Jun Xia Tianyi Wu Huanqi Ni Erping Long Ji-Peng Olivia Li Lanqin Zhao Ruoxi Chen Ruixin Wang Yanwu Xu Kai Huang Haotian Lin | 2022 | Intelligent Medicine2022，2，3： | 0 |
