2PCT:Point cloud transformer显示文摘The irregular domain and lack of ordering make it challenging to design deep neural networks for point cloud processing.This paper presents a novel framework named Point Cloud Transformer(PCT)for point cloud learning.PCT is based on Transformer,which achieves huge success in natural language processing and displays great potential in image processing.It is inherently permutation invariant for processing a sequence of points,making it well-suited for point cloud learning.To better capture local context within the point cloud,we enhance input embedding with the support of farthest point sampling and nearest neighbor search.Extensive experiments demonstrate that the PCT achieves the state-of-the-art performance on shape classification,part segmentation,semantic segmentation,and normal estimation tasks.Meng-Hao Guo Jun-Xiong Cai Zheng-Ning Liu Tai-Jiang Mu Ralph R.Martin Shi-Min Hu 2021Computational Visual Media2021,7,2:55
3Wet Cupping Therapy Improves Local Blood Perfusion and Analgesic Effects in Patients with Nerve-Root Type Cervical Spondylosis显示文摘Objective: To observe wet cupping therapy(WCT) on local blood perfusion and analgesic effects in patients with nerve-root type cervical spondylosis(NT-CS). Methods: Fifty-seven NT-CS patients were randomly divided into WCT group and Jiaji acupoint-acupuncture(JA) group according a random number table. WCT group(30 cases) was treated with WCT for 10 min, and JA group(27 cases) was treated with acupuncture for 10 min. The treatment efficacies were evaluated with a Visual Analogue Scale(VAS). Blood perfusion at Dazhui(GV 14) and Jianjing(GB 21) acupoints(affected side) was observed with a laser speckle flowmetry, and its variations before and after treatment in both groups were compared as well. Results: In both groups, the VAS scores significantly decreased after the intervention(P<0.01), while the blood perfusion at the two acupoints significantly increased after intervention(P<0.05); however, the increasement magnitude caused by WCT was obvious compared with JA(P<0.05). Conclusion: WCT could improve analgesic effects in patients with NT-CS, which might be related to increasing local blood perfusion of acupunct points.MENG Xiang-wen WANG Ying PIAO Sheng-ai LV Wen-tao ZHU Cheng-hui MU Ming-yuan LI Dan-dan LIU Hua-peng GUO Yi 2018Chinese Journal of Integrative Medicine2018,24,11:33
4Attention mechanisms in computer vision:A survey显示文摘Humans can naturally and effectively find salient regions in complex scenes.Motivated by this observation,attention mechanisms were introduced into computer vision with the aim of imitating this aspect of the human visual system.Such an attention mechanism can be regarded as a dynamic weight adjustment process based on features of the input image.Attention mechanisms have achieved great success in many visual tasks,including image classification,object detection,semantic segmentation,video understanding,image generation,3D vision,multimodal tasks,and self-supervised learning.In this survey,we provide a comprehensive review of various attention mechanisms in computer vision and categorize them according to approach,such as channel attention,spatial attention,temporal attention,and branch attention;a related repository http://gffzz188fe103f8f1460ascbnvvvk9w5xc6qkc.ffgz.tsg.suse.edu.cn/MenghaoG uo/Awesome-Vision-Attentions is dedicated to collecting related work.We also suggest future directions for attention mechanism research.Meng-Hao Guo Tian-Xing Xu Jiang-Jiang Liu Zheng-Ning Liu Peng-Tao Jiang Tai-Jiang Mu Song-Hai Zhang Ralph R.Martin Ming-Ming Cheng Shi-Min Hu 2022Computational Visual Media2022,8,3:27
5Current status of diagnosis and treatment of bladder cancer in China-Analyses of Chinese Bladder Cancer Consortium database显示文摘Objective:To investigate current status of diagnosis and treatment of bladder cancer in China.Methods:A database was generated by Chinese Bladder Cancer Consortium(CBCC).From January 2007 to December 2012,14,260 cases from 44 CBCC centers were included.Data of diagnosis,treatment and pathology were collected.Results:The average age was 63.5 year-old and most patients were male(84.3%).The most common histologic types were urothelial carcinoma(91.4%),adenocarcinoma(1.8%),and squamous carcinoma(1.9%).According to 1973 and 2004 WHO grading system,42.0%,41.0%,and 17.0% of patients were grade 1,2,and 3,and 16.0%,48.7%,and 35.3% of patients were papillary urothelial neoplasms of low malignant potential,low,and high grade,respectively.Non-muscle invasive bladder cancer(NMIBC)and muscle invasive bladder cancer(MIBC)were 25.2% and 74.1%,respectively(0.8% not clear).Carcinoma in situ was only 2.4%.Most patients were diagnosed by white-light cystoscopy with biopsy(74.3%).Fluorescence and narrow band imaging cystoscopy had additional detection rate of 1.0% and 4.0%,respectively.Diagnostic transurethral resection(TUR)provided detection rate of 16.9%.Most NMIBCs were treated with TUR(89.2%).After initial TUR,2.6%accepted second TUR,and 45.7%,69.9%,and 58.7% accepted immediate,induced,and maintenance chemotherapy instillation,respectively.Most MIBCs were treated with radical cystectomy(RC,59.7%).Laparoscopic RCs were 35.1%,while open RC 63.4%.Extended and standard pelvic lymph node dissection were 7% and 66%,respectively.Three most common urinary diversions were orthotopic neobladder(44%),ileal conduit(31%),and ureterocutaneostomy(23%).Only 2.3% of patients accepted neo-adjuvant chemotherapy and only 18%of T3 and T4 patients accepted adjuvant chemotherapy.Conclusion:Disease characteristics are similar to international reports,while differences of diagnosis and treatment exist.This study can provide evidences for revisions of the guideline on bladder cancer in China.Kaiwen Li Tianxin Lin Wei Xue Xin Mu Enci Xu Xu Yang Fubao Chen Guangyong Li Lulin Ma Guoliang Wang Chaozhao Liang Haoqiang Shi Ming Li Mao Tang Xueyi Xue Yisong Lv Yaoliang Deng Chengyang Li Zhiwen Chen Xiaozhou Zhou Fengshuo Jin Xudong Liu Jinxin Wei Lei Shi Xin Gou Weiyang He Liqun Zhou Lin Cai Baiye Jin Guanghou Fu Xiangbo Kong Hongyan Sun Ye Tian Lang Feng Tiejun Pan Yiyi Wu Dongwen Wang Hailong Hao Benkang Shi Yaofeng Zhu Qiang Wei Ping Han Changli Wu Dawei Tian Zhangqun Ye Zheng Liu Zhiping Wang Junqiang Tian Lin Qi Minfeng Chen Wei Li Jinchun Qi Gongxian Wang Longlong Fu Zhaolin Sun Guangheng Luo Zhoujun Shen Zhaowei Zhu Jinchun Xing Zhun Wu Dong Wei Xin Chen Yanqun Na Hongfeng Guo Chunxi Wang Zhihua Lu Chuize Kong Yang Liu Jin Yang Jianyun Hu Xin Gao Jielin Li Changjun Yin Pu Li Shan Chen Zhen Du Jiongming Li Yongji Yan Xu Zhang Shuang Huang Fangjian Zhou Zhiling Zhang Yinghao Sun Shuxiong Zeng Song Cen Jiaquan Zhou Hanzhong Li Jin Wen Jian Huang 2015Asian Journal of Urology2015,2,2:21

8Sequential use of transarterial chemoembolization and percutaneous cryosurgery for hepatocellular carcinoma显示文摘AIM: To evaluate the efficacy of sequential use of transarterial chemoembolization (TACE) and percutaneous cryosurgery for unresectable hepatocellular carcinoma (HCC). METHODS: Four hundred and twenty patients were enrolled in this study. The patients, who were considered to have unresectable tumors due to their location or size or comorbidity, were divided into sequential TACE-cryosurgery (sequential) group (n = 290) and cryosurgery alone (cryoalone) group (n = 130). Patients in the sequential group tended to have larger tumors and a greater number of tumors than those in the cryo-alone group. Tumors larger than 10 cm in diameter were only seen in the sequential group. TACE was performed with the routine technique and percutaneous cryosurgery was conducted under the guidance of ultrasound 2-4 wk after TACE. RESULTS: During a mean follow-up period of 42 ± 17 mo (range, 24-70 mo), the local recurrence rateat the ablated area was 17% for all patients, 11% and 23% for patients in sequential group and cryoalone groups, respectively (P = 0.001). The overall 1-, 2-, 3-, 4and 5-year survival rate was 72%, 57%, 47%, 39% and 31%, respectively. The 1and 2-year survival rates (71% and 61%) in sequential group were similar to those (73% and 54%) in cryo-alone group (P = 0.69 and 0.147), while the 4and 5-year survival rates were 49% and 39% in sequential group, higher than those (29% and 23%) in cryo-alone group (P = 0.001). Eighteen patients with large HCC (> 5 cm in diameter) survived for more than 5 years after sequential TACE while no patient with large HCC (> 5 cm in diameter) survived more than 5 years after cryosurgery. The overall complication rate was 24%, and the complication rates were 21% and 26% for the sequential and cryo-alone groups, respectively (P = 0.06). The incidence of hepatic bleeding was higher in cryo-alone group than in sequential group (P = 0.02). Liver crack only occurred in two patients of the cryoalone group. CONCLUSION: Pre-cryosurgical TACE can increase the cryoablation efficacy and decrease its adverse effects, especially bleeding. Sequential TACE and cryosurgery may be the better procedure for unresectable HCC, especially for large HCC.Ke-Cheng Xu Li-Zhi Niu Qiang Zhou Yi-Ze Hu De-Hong Guo Zheng-Ping Liu Bing Lan Feng Mu Ying-Fei Li Jian-Sheng Zuo 2009World Journal of Gastroenterology2009,15,29:13
9Pediatric reference intervals in China(PRINCE):design and rationale for a large,multicenter collaborative cross-sectional study显示文摘There is a lack of accurate pediatric reference intervals(RIs) in China, with most commonly used RIs established without consideration of the effect of age and gender. The Pediatric Reference Intervals in China(PRINCE) project aims to establish and verify pediatric RIs for 31 common laboratory measurands.The project will be a large, multicenter cross-sectional study:14,490 healthy children and adolescents aged up to 19 years will be surveyed by 10 children's hospitals and one pediatric department of a university hospital. To evaluate the feasibility and efficiency of the study methods, 602 children were surveyed in the pilot phase of the PRINCE study in April 2017: it found that some measurands were distinctly age dependent and that there were differences between values for males and females. The results of the pilot study affirmed the necessity of the PRINCE project for Chinese pediatrics. The pilot also indicated potential difficulties in the full survey, e.g., difficulties in recruiting children aged under 3 years and insufficient collection of blood samples from infants. The operation of the PRINCE project has been modified based on the findings in the pilot study toward improving the validity of the PRINCE project and promoting its openness and transparency.Xin Ni Wenqi Song Xiaoxia Peng Ying Shen Yaguang Peng Qiliang Li Yan Wang Lixin Hu Yanying Cai Hong Shang Min Zhao Hong Jiang Yaoguo Huang Runqing Mu Wenxiang Chen Mingting Peng Chuanbao Zhang Jie Zeng Chenbin Li Hongling Yang Yongmei Jiang Jin Xu Guixia Li Hongbing Chen Yun Xiang Sancheng Cao Zhenxin Guo Dapeng Chen 2018Science Bulletin2018,63,24:12
10Robust MVDR beamforming based on covariance matrix reconstruction显示文摘The minimum variance distortionless response(MVDR) beamformer has better resolution and much better interference rejection capability than the data-independent beamformers.However,the former is more sensitive to errors,such as the steering vector errors caused by direction of arrival mismatch,imprecise array calibration or any other possible factors,especially in the case of high signal-to-noise ratio(SNR).A new robust MVDR beamformer against the general steering vector errors is proposed in this paper.This method is based on the reconstruction of the covariance matrix which aims to reduce the power of the signal of interest(SOI) in the covariance matrix.The eigenanalysis is used in the process of removing the SOI component and modifying the residual covariance matrix.Simulation results show that the proposed method has excellent signal-to-interference-plus-noise ratio(SINR) performance under the mismatch condition.MU PengCheng LI Dan YIN QinYe GUO Wei 2013Science China(Information Sciences)2013,56,4:11
11Semaphorin 4D and hypoxia-inducible factor-1α overexpression is related to prognosis in colorectal carcinoma显示文摘AIM:To investigate semaphorin 4D(Sema4D)and hypoxia-inducible factor-1α(HIF-1α)expression in colorectal carcinoma and evaluate their clinicopathological and prognostic significance.METHODS:Eighty-six curatively resected colorectal carcinoma patients at different stages of disease were randomly selected from the group of patients who underwent surgery,and none of them received preoperative radiochemotherapy.Normal proximal adjacent bowel tissue,which served as an internal control,was obtained from 52 randomly selected patients.Immunohistochemistry was performed to analyze the expression of Sema4D and the tumor angiogenesisrelated protein HIF-1αin normal colorectal tissues and colorectal carcinoma tissues.The relationships between the expression and clinical characters and prognosis were analyzed.RESULTS:HIF-1αand Sema4D were positively expressed in 58%and 60%of colorectal carcinoma tissues,respectively.Significantly lower expression levels were observed in normal mucosa(8%and 12%,respectively).HIF-1αand Sema4D expression was closely correlated with histological tumor type,tumornode-metastasis(TNM)stage,and lymphatic metastasis(P<0.05),but not with age or tumor size(P>0.05).HIF-1αand Sema4D protein expression was significantly correlated with prognosis of colorectal carcinoma,as determined by Spearman rank correlation analysis(r=0.567;P<0.01).Multivariate Cox analysis revealed that only Sema4D expression played a significant role in predicting patient prognosis(P<0.05).CONCLUSION:These findings suggest that HIF-1αand Sema4D expression correlates with histological tumor type,TNM stage,and lymphatic metastasis in colorectal carcinoma and that Sema4D is a prognostic indicator of colorectal carcinoma.Jin-Shen Wang Chang-Qing Jing Ke-Shu Shan Yue-Zhi Chen Xiao-Bo Guo Zhi-Xin Cao Lin-Jun Mu Li-Pan Peng Ming-Liang Zhou Le-Ping Li 2015World Journal of Gastroenterology2015,21,7:10
12Three new alkaloids isolated from the stem tuber of Pinellia pedatisecta显示文摘The present study was designed to determine the chemical constituents of the stem tuber of Pinellia pedatisecta. The chemical constituents were isolated and purified by various chromatographic techniques, and their structures were elucidated on the basis of physicochemical properties and spectral data. Three new alkaloids(compounds 1, 2, and 3) were obtained and identified as 9-((5-methoxypyridin-2-yl)methyl)-9 H-purin-6-amine(1), 4-(2-(2, 5-dioxopyrrolidin-1-yl)ethyl)phenyl acetate(2), and N-(9-((5-methoxypyridin-2-yl)methyl)-9 H-purin-6-yl)acetamide(3). These compounds were evaluated for their cytotoxicity against human cervical cancer He La cells. Compounds 1 and 3 significantly inhibited the proliferation of He La cells with IC_(50) values being 3.02 ± 0.54 and 7.16 ± 0.62 μmol·L^(-1), respectively.DU Jing DING Jie MU Zhen-Qiang GUAN Shu-Hong CHENG Chun-Ru LIU Xuan GUO De-An 2018Chinese Journal of Natural Medicines2018,16,2:10
13Profound thrombocytopenia induced by clopidogrel with a prior history of long-term safe administration显示文摘Clopidogrel has shown an excellent safety,tolerability and efficacy ever since its marketing.However,here we report a rare case with profound thrombocytopenia following clopidogrel administration previously safely exposed to this same drug.This reminds us that thrombocytopenia might be induced by clopidogrel even with a prior,safe history of long-term administration.Yuan-Lin Guo Jian-Jun Li Jin-Qing Yuan Xue-Wen Qin Xin Zheng Chao-Wei Mu Yi-Hong Hua 2010World Journal of Cardiology2010,2,6:9
14Characterization of peach tree crown by using high-resolution images from an unmanned aerial vehicle显示文摘In orchards, measuring crown characteristics is essential for monitoring the dynamics of tree growth and optimizing farm management. However, it lacks a rapid and reliable method of extracting the features of trees with an irregular crown shape such as trained peach trees. Here, we propose an efficient method of segmenting the individual trees and measuring the crown width and crown projection area (CPA) of peach trees with time-series information, based on gathered images. The images of peach trees were collected by unmanned aerial vehicles in an orchard in Okayama, Japan, and then the digital surface model was generated by using a Structure from Motion (SfM) and Multi-View Stereo (MVS) based software. After individual trees were identified through the use of an adaptive threshold and marker-controlled watershed segmentation in the digital surface model, the crown widths and CPA were calculated, and the accuracy was evaluated against manual delineation and field measurement, respectively. Taking manual delineation of 12 trees as reference, the root-mean-square errors of the proposed method were 0.08 m (R^(2) = 0.99) and 0.15 m (R^(2) = 0.93) for the two orthogonal crown widths, and 3.87 m2 for CPA (R^(2) = 0.89), while those taking field measurement of 44 trees as reference were 0.47 m (R^(2) = 0.91), 0.51 m (R^(2) = 0.74), and 4.96 m2 (R^(2) = 0.88). The change of growth rate of CPA showed that the peach trees grew faster from May to July than from July to September, with a wide variation in relative growth rates among trees. Not only can this method save labour by replacing field measurement, but also it can allow farmers to monitor the growth of orchard trees dynamically.Yue Mu Yuichiro Fujii Daisuke Takata Bangyou Zheng Koji Noshita Kiyoshi Honda Seishi Ninomiya Wei Guo 2018Horticulture Research2018,5,1:9
15Synthesis and thermal properties of poly(styrene-co-acrylonitrile)-graft-polyethylene glycol copolymers as novel solid–solid phase change materials for thermal energy storage显示文摘A novel poly(styrene-co-acrylonitrile)-graft-polyethylene glycol(SAN-g-PEG) copolymer was synthesized as new solid–solid phase change materials(SSPCMs) by grafting PEG to the main chain of poly(styrene-co-acrylonitrile). The chemical structure of the SAN-g-PEG was confirmed by the Fourier transform infrared(FT-IR) and proton nuclear magnetic resonance(1H NMR) spectroscopy techniques. The thermal energy storage properties and the storage durability of the SAN-g-PEG were investigated by differential scanning calorimetry(DSC). The SAN-g-PEG was endowed with the solid–solid phase transition temperatures within the range of 23–36 8C and the latent heat enthalpy ranged from 66.8 k J/kg to 68.3 k J/kg. Thermal cycling tests revealed that the SAN-g-PEG kept great heat storage durability after 1000 thermal cycles. The thermal stability was evaluated by a thermal gravity analysis(TGA), and the initial decomposition temperature(Td) of SAN-g-PEG is 350 8C, which proves that the SAN-g-PEG possessed good thermal stability.Si-Yang Mu Jing Guo Yu-Mei Gong Sen Zhang Yue Yu 2015Chinese Chemical Letters2015,26,11:9
16Effect of Hydrogen Addition on Low Temperature Metallurgical Property of Sinter显示文摘Hydrogen-enrich iron making process is certainly to be an effective method to reduce greenhouse gases emission.However,the effect of hydrogen addition on the low temperature metallurgical property of sinter is still unclear.A detailed investigation was performed on the above topic.The results are as follows.When CO is partially replaced by H2,the RDI<3.15(RDI<2.8) of sinter decreases with the increase of the H2 content;when the content of H2 increases,the CO,CO2 and N2 decrease proportionally,in this case,RDI<3.15(RDI<2.8) of sinter increases with the increase of H2 content;the value of RDI<3.15(RDI<2.8) basically depends on the reduction index(Ri).The experimental data of RDI<2.8 based on Japanese industrial standard(JIS) are a little higher than the data of RDI<3.15 based on Chinese industrial standard(CIS) in the same condition.In addition,for part of CO is replaced by H2:RDI<2.8=3.38394+1.1585 RDI<3.15;for other gases,except H2,are decreased proportionally:RDI<2.8=17.39678+0.42922 RDI<3.15.MU Lin JIANG Xin GAO Qiang-jian WEI Guo SHEN Feng-man 2012Journal of Iron and Steel Research(International)2012,19,4:8
17Toripalimab plus chemotherapy as second-line treatment in previously EGFR-TKI treated patients with EGFR-mutant-advanced NSCLC:a multicenter phase-II trial显示文摘This multicenter phase-II trial aimed to investigate the efficacy,safety,and predictive biomarkers of toripalimab plus chemotherapy as second-line treatment in patients with EGFR-mutant-advanced NSCLC.Patients who failed from first-line EGFR-TKIs and did not harbor T790M mutation were enrolled.Toripalimab plus carboplatin and pemetrexed were administrated every three weeks for up to six cycles,followed by the maintenance of toripalimab and pemetrexed.The primary endpoint was objective-response rate(ORR).Integrated biomarker analysis of PD-L1 expression,tumor mutational burden(TMB),CD8+tumor-infiltrating lymphocyte(TIL)density,whole-exome,and transcriptome sequencing on tumor biopsies were also conducted.Forty patients were enrolled with an overall ORR of 50.0%and disease-control rate(DCR)of 87.5%.The median progression free survival(PFS)and overall survival were 7.0 and 23.5 months,respectively.The most common treatment-related adverse effects were leukopenia,neutropenia,anemia,ALT/AST elevation,and nausea.Biomarker analysis showed that none of PD-L1 expression,TMB level,and CD8+TIL density could serve as a predictive biomarker.Integrated analysis of whole-exome and transcriptome sequencing data revealed that patients with DSPP mutation had a decreased M2 macrophage infiltration and associated with longer PFS than those of wild type.Toripalimab plus chemotherapy showed a promising anti-tumor activity with acceptable safety profiles as the second-line setting in patients with EGFR-mutant NSCLC.DSPP mutation might serve as a potential biomarker for this combination.A phase-III trial to compare toripalimab versus placebo in combination with chemotherapy in this setting is ongoing(NCT03924050).Tao Jiang Pingyang Wang Jie Zhang Yanqiu Zhao Jianying Zhou Yun Fan Yongqian Shu Xiaoqing Liu Helong Zhang Jianxing He Guanghui Gao Xiaoqian Mu Zhang Bao Yanjun Xu Renhua Guo Hong Wang Lin Deng Ningqiang Ma Yalei Zhang Hui Feng Sheng Yao Jiarui Wu Luonan Chen Caicun Zhou Shengxiang Ren 2021Signal Transduction and Targeted Therapy2021,6,11:8

19KAI1/CD82 suppresses hepatocyte growth factorinduced migration of hepatoma cells via upregulationof Sprouty2显示文摘We conducted a study concerning the suppressive mechanism of KAI1/CD82 on hepatoma cell metastasis.Hepatocyte growth factor(HGF)induces the migration of hepatoma cells through activation of cellular sphingosine kinase 1(SphK1).Adenovirus-mediated gene transfer of KAI1(Ad-KAI1)downregulates the SphK1 expression and suppresses the HGF-induced migration of SMMC-7721 human hepatocellcular carcinoma cells.Overexpression of KAI1/CD82 significantly elevates Sprouty2 at the protein level.Ablation of Sprouty2 with RNA interference can block the KAI1/CD82-induced suppression of hepatoma cell migration and downregulation of SphK1 expression.It is demonstrated that KAI1/CD82 suppresses HGF-induced migration of hepatoma cells via upregulation of Sprouty2.MU ZhenBin1 ,3,WANG Hua 2,ZHANG Jing 2,LI QingFang 2,WANG LiSheng 2&GUO XiaoZhong 3 1State Key Laboratory of Cancer Biology and Institute of Digestive Diseases,Xijing Hospital,Fourth Military Medical University,Xi’an 710032,China 2Department of Experimental Hematology,Beijing Institute of Radiation Medicine,Beijing 100850,China 3Department of Gastroenterology,Shenyang General Hospital of PLA,Shenyang 110016,China 2008Science China(Life Sciences)2008,51,7:7
20Newborn screening with targeted sequencing:a multicenter investigation and a pilot clinical study in China显示文摘Different newborn screening(NBS) programs have been practiced in many countries since the 1960 s. It is of considerable interest whether next-generation sequencing is applicable in NBS. We have developed a panel of 465 causative genes for 596 early-onset, relatively high incidence, and potentially actionable severe inherited diseases in our Newborn Screening with Targeted Sequencing(NESTS) program to screen 11,484 babies in 8 Women and Children’s hospitals nationwide in China retrospectively. The positive rate from preliminary screening of NESTS was 7.85%(902/11,484). With 45.89%(414/902) follow-up of preliminary positive cases, the overall clinically confirmative diagnosis rate of monogenic disorders was 12.07%(50/414), estimating an average of 0.95%(7.85% × 12.07%) clinical diagnosis rate, suggesting that monogenic disorders account for a considerable proportion of birth defects. The disease/gene spectrum varied in different regions of China. NESTS was implemented in a hospital by screening 3923 newborns to evaluate its clinical application. The turn-around time of a primary report, including the sequencing period of < 7 days, was within 11 days by our automatic interpretation pipeline. Our results suggest that NESTS is feasible and cost-effective as a first-tier NBS program, which will change the status of current clinical practice of NBS in China.Chanjuan Hao Ruolan Guo Xuyun Hu Zhan Qi Qi Guo Xuanshi Liu Yuanhu Liu Yanhua Sun Xiaofen Zhang Feng Jin Xiujie Wu Ren Cai Dingyuan Zeng Xijiang Hu Xiaohua Wang Xiaoping Ji Wenjie Li Quansheng Xing Lanfang Mu Xiulian Jiang Xue Yang Weimin Yang Yan Zhang Qianli Yin Xin Ni Wei Li 2022Journal of Genetics and Genomics2022,49,1:7
