1Malnutrition and Quality of Life in Chinese Cancer Patients: a Clinical Study of 23,994 Subjects显示文摘Background Malnutrition is common in patients with cancer,and can negatively impact their quality of life(QoL)and even survival.However,there is currently no large data available on the prevalence of malnutrition in Chinese cancer patients.This study evaluated the prevalence of malnutrition and the QoL of Chinese patients with locoregional,recurrent or metastatic cancer.Methods We conducted a nationwide observational,multi-center,hospital-based cross-sectional study within the Chinese Society of Nutritional Oncology(CSNO)Network.All of the patients were diagnosed with one of the following 18 different types of malignant tumors:lung cancer,gastric cancer,liver cancer,colorectal cancer,breast cancer,esophageal cancer,cervical cancer,endometrial cancer,nasopharyngeal carcinoma,malignant lymphoma,leukemia,pancreatic cancer,ovarian cancer,prostate cancer,bladder cancer,brain cancer,biliary tract malignant tumors or gastrointestinal stromal tumors.These patients were enrolled from 72 hospitals located in different regions of China.The patients’nutritional status was evaluated based on the body mass index(BMI),loss of bodyweight,laboratory measurements and patient generated-subjective global assessment(PG-SGA)scores.The cancer patients’physical status and QoL were assessed by the Karnofsky Performance Status(KPS)questionnaire and the European Organization for Research and Treatment of Cancer(EORTC)QLQ-C30 questionnaire,respectively.Results From December 2013 to April 2016,23,994 patients hospitalized for cancer treatment(such as surgery,chemotherapy or radiotherapy)were enrolled in the study.The patients included 12,494(52.9%)males and 11,124(47.1%)females.The mean age was 55.8±13.7 years.The proportions of patients in cancer stagesⅠ,Ⅱ,Ⅲ,Ⅳand uncertain were 11.5%,20.3%,27.5%,30.2%and 10.5%,respectively.Among the 23,994 inpatients,the proportions of patients who were underweight(BMI<18.5 kg/m2),normal(18.5 kg/m2Hong Xia Xu Chun Hua Song Zhen Ming Fu Chang Wang Zeng Qing Guo Yuan Lin Ying Ying Shi Wen Hu Yi Ba Su Yi Li Zeng Ning Li Kun Hua Wang Jing Wu Ying He Jia Jun Yang Cong Hua Xie Fu Xiang Zhou Xin Xia Song Gong Yan Chen Wen Jun Ma Su Xia Luo Zi Hua Chen Ming Hua Cong Hu Ma Chun Ling Zhou Wei Wang Qi Luo Yong Mei Shi Yu Mei Qi Hai Ping Jiang Wen Xian Guan Jun Qiang Chen Jia Xin Chen Yu Fang Lan Zhou Yong Dong Feng Rong Shao Tan Tao Li Jun Wen Ou Qing Chuan Zhao Jian Xiong Wu Min Weng Qing Hua Yao Jiu Wei Cui Wei Li Han Ping Shi the Investigation on Nutrition Status and Clinical Outcome of Common Cancers(INSCOC)Group 2021Journal of Nutritional Oncology2021,6,1:8
2Validity of the Chinese Version of the Patient-Generated Subjective Global Assessment (PG-SGA) in Lung Cancer Patients显示文摘The prevalence of malnutrition is high among oncology patients in China. Although the Patient- Generated Subjective Global Assessment (PG-SGA) is widely recognized as an important nutritional assessment tool, it has not been validated for Chinese cancer patients. The purpose of this study was to conduct an analysis of nutrition screening and assessment data to validate the Chinese version of the PG-SGA in Chinese patients with lung cancer. This was an observational, cross-sectional study of 2,000 consecutive adult patients with lung cancer treated at several tertiary hospitals in China. Anthropometric and patient descriptive data were collected. The PG-SGA generated a score for the nutritional risk and a global rating for the nutritional status. The internal consistency, external consistency, and construct validity were evaluated, and a known-groups comparison and principal component analyses were conducted to evaluate the reliability and validity of the PG-SGA. The known-groups comparison demonstrated the ability of the PG-SGA to differentiate lung cancer patients of different nutritional and body mass index (BMI) groups. A confirmatory factor analysis supported the original four-factor structure of the PG-SGA. In terms of the internal and external consistency, the PG-SGA demonstrated intra-class correlation coefficients (ICC) up to 0.987. Alternative form validity was also demonstrated between Box 4 of the PG-SGA and the Karnofsky Performance Status score, with excellent external consistency (r = 0.972, P < 0.001). The construct validity was supported, and selected questionnaire dimensions were evident in the principal component analysis. Significant Spearman correlations (P < 0.001) were demonstrated. The Chinese version of the PG-SGA demonstrated significant reliability and sufficient exploratory properties to support its validity. It seems to be a valid tool that can be used to access the nutritional status of Chinese lung cancer patients. The validity of the PG-SGA in Chinese cancer patients warrants further investigation in other cancer types.Zhen Ming Fu Hong Xia Xu Chun Hua Song Wei Li Zeng Qing Guo Yuan Lin Ying Ying Shi Wen Hu Yi Ba Su Yi Li Zeng Ning Li Kun Hua Wang Jing Wu Ying He Jia Jun Yang Cong Hua Xie Xin Xia Song Gong Yan Chen Wen Jun Ma Su Xia Luo Zi Hua Chen Ming Hua Cong Hu Ma Chun Ling Zhou Wei Wang Qi Luo Yong Mei Shi Yu Mei Qi Hai Ping Jiang Wen Xian Guan Jun Qiang Chen Jia Xin Chen Yu Fang Lan Zhou Yong Dong Feng Rong Shao Tan Tao Li Jun Wen Ou Qing Chuan Zhao Jian Xiong Wu Chang Wang Han Ping Shi The Investigation on Nutrition Status and Clinical Outcome of Common Cancers (INSCOC) Group 2016Journal of Nutritional Oncology2016,1,1:7
3Loss of Gn1a/OsCKX2 confers heavy-panicle rice with excellent lodging resistance显示文摘Significant achievements have been made in breeding programs for the heavy-panicle-type(HPT)rice(Oryza sativa) in Southwest China. The HPT varieties now exhibit excellent lodging resistance,allowing them to overcome the greater pressures caused by heavy panicles. However, the genetic mechanism of this lodging resistance remains elusive. Here, we isolated a major quantitative trait locus, Panicle Neck Diameter 1(PND1), andidentified the causal gene as GRAIN NUMBER 1 A/CYTOKININ OXIDASE 2(Gn1 A/Os CKX2). The null gn1 a allele from rice line R498(gn1 aR498) improved lodging resistance through increasing the culm diameter and promoting crown root development.Loss-of-function of Gn1 a/Os CKX2 led to cytokinin accumulation in the crown root tip and accelerated the development of adventitious roots. Gene pyramiding between the null gn1 aR498 allele with two gain-of-function alleles, STRONG CULM 2(SCM2)and SCM3, further improved lodging resistance.Moreover, Gn1 a/Os CKX2 had minimal influence on overall rice quality. Our research thus highlights the distinct genetic components of lodging resistance of HPT varieties and provides a strategy for tailormade crop improvement of both yield and lodging resistance in rice.Bin Tu Zhang Tao Shiguang Wang Lei Zhou Ling Zheng Chun Zhang Xinzi Li Xiaoyu Zhang Junjie Yin Xiaobo Zhu Hua Yuan Ting Li Weilan Chen Peng Qin Bingtian Ma Yuping Wang Shigui Li 2022Journal of Integrative Plant Biology2022,64,1:5
4Validity of the Chinese Version of the Patient-Generated Subjective Global Assessment (PG-SGA) in Gastric Cancer Patients显示文摘Purpose Malnutrition is severe among gastric cancer patients in China. While the Patient-Generated Subjective Global Assessment (PG-SGA) is a widely used nutritional assessment tool, the validation for Chinese patients with gastric cancer has not been performed yet. The aim of this research is to validate the Chinese version of the PGSGA in Chinese gastric cancer patients by conducting analyses of nutrition screening and assessment data. Methods Two thousand consecutive adult patients with gastric cancer were included in this observational, cross-sectional study in several tertiary hospitals in China. A survey was made among those patients, which included several questionnaires and some anthropometric parameters. We calculated the parameters to validate the use of PG-SGA categorizing the nutritional status of gastric cancer patients. Then we performed statistical analysis to evaluate the internal consistency, external consistency, and construct validity. Results This study verified the ability of the PG-SGA to differentiate gastric cancer patients into different nutritional groups. The confirmatory factor analysis verified the original four-factor structure of the PG-SGA. The internal and external consistency was measured by a concordance analysis which showed an intraclass correlation coefficients (ICC) of 0.987. The correlations of the Box 4 score with the Karnofsky performance status score demonstrated alternative form validity with good external consistency (Pearson, r = 0.643, P < 0.001). All three anthropometric dimensions of the PG-SGA were supported by principal component analysis. Spearman correlations (P < 0.001) were significant in the majority of tests. Conclusion The Chinese version of the PG-SGA is a valid tool to access the patients’ nutritional status for Chinese gastric patients.Zhen Ming Fu Hong Xia Xu Chun Hua Song Wei Li Zeng Qing Guo Yuan Lin Ying Ying Shi Wen Hu Yi Ba Su Yi Li Zeng Ning Li Kun Hua Wang Jing Wu Ying He Jia Jun Yang Cong Hua Xie Xin Xia Song Gong Yan Chen Wen Jun Ma Su Xia Luo Zi Hua Chen Ming Hua Cong Hu Ma Chun Ling Zhou Wei Wang Qi Luo Yong Mei Shi Yu Mei Qi Hai Ping Jiang Wen Xian Guan Jun Qiang Chen Jia Xin Chen Yu Fang Lan Zhou Yong Dong Feng Rong Shao Tan Tao Li Jun Wen Ou Qing Chuan Zhao Jian Xiong Wu Chang Wang Han Ping Shi The Investigation on Nutrition Status and Clinical Outcome of Common Cancers (INSCOC) Group 2018Journal of Nutritional Oncology2018,3,4:5

6Extension Protocol for the Investigation on Nutrition Status and Clinical Outcome of Patients with Common Cancers in China(INSCOC)Study:2021 update显示文摘Background Malnutrition is common in patients with cancer,and this adversely affects the survival and quality of life of patients.Chinese Society for Nutritional Oncology issued a multi-center,large-scale,long-term follow-up prospective study,the Investigation on Nutrition Status and Clinical Outcome of Patients with Common Cancers in China(INSCOC study)since 2013.This is an extension to the previous 2013-2020 study protocol.This study still sought to:①address the prognostic impact of nutritional factors and quality of life on cancer patient survival;②describe the overall and cancer-specific incidence and/or distribution of malnutrition and different measurements of patient quality of life.Methods and study design This is an observational,multi-centered,hospital-based prospective cohort study.Data collection will be performed at baseline(within 48 hours after patient admission),during the hospital stay and 30 days after hospital admission.Follow-up will be conducted for 1-20 years after enrollment.The primary outcome will be the all-cause mortality/overall survival,and secondary outcomes will be the length of hospital stay and costs of hospitalization.Study factors will include demographic characteristics,tumor characteristics,information about chronic diseases,hematological measurements(e.g.,red blood cell count,total lymphocyte counts,hemoglobin,albumin,prealbumin,creatinine,C-reactive protein,IL-6),anthropometric measurements(e.g.,height,weight,arm circumference,arm muscle circumference,triceps skinfold thickness,and waist circumference),body composition parameters,PG-SGA scores,quality of life(as indicated by the QLQ-C30 questionnaire),muscle mass(as indicated by the calf circumference),muscle strength(as indicated by the handgrip strength),muscle function(as indicated by the six-meter walking speed test)and physical status assessments(as indicated by the Karnofsky Performance Status scores).This clinical study protocol was approved by local Ethics Committees of all the participating hospitals.Written informed consent is required for each subject included.Discussion This multi-center,large-scale,long-term follow up prospective study will help improve the diagnosis of malnutrition in cancer patients and identify the risk factors associated with adverse clinical outcomes.The anticipated results of this study will highlight the need for a truly scientific appraisal of nutrition therapy in Chinese oncology populations,and finally help treat the potentially reversible elements of malnutrition in cancer patients to improve their clinical outcomes in the future.Hong Xia Xu Chun Hua Song Liang Yu Yin Chang Wang Zhen Ming Fu Zeng Qing Guo Yuan Lin Ying Ying Shi Wen Hu Yi Ba Su Yi Li Zeng Ning Li Kun Hua Wang Jing Wu Ying He Jia Jun Yang Cong Hua Xie Fu Xiang Zhou Xin Xia Song Gong Yan Chen Wen Jun Ma Su Xia Luo Zi Hua Chen Zhi Kang Chen Ming Hua Cong Hu Ma Chun Ling Zhou Wei Wang Qi Luo Yong Mei Shi Yu Mei Qi Hai Ping Jiang Wen Xian Guan Jun Qiang Chen Xiang Hua Wu Jia Xin Chen Yu Fang Lan Zhou Yong Dong Feng Rong Shao Tan Tao Li Jun Wen Ou Qing Chuan Zhao Jian Xiong Wu Min Weng Qing Hua Yao Ya Yin Yu Quan Jun Lyu Hong Qiu Ming Liu Wei Li Han Ping Shi The Investigation on Nutrition Status and Clinical Outcome of Common Cancers(INSCOC)Group 2022Journal of Nutritional Oncology2022,7,2:3
7Environmental Monitoring of A Laboratory for New Coronavirus Nucleic Acid Testing显示文摘The coronavirus disease 2019(COVID-19) is an infection of the respiratory tract which first broke out in Wuhan, China, in December 2019. The etiologic agent of this disease was identified as a betacoronavirus related to severe acute respiratory syndrome coronavirus(SARS-CoV). Thus, the International Committee on Virus Classification named the new coronavirus severe acute respiratory syndrome coronavirus-2(SARS-CoV-2)[1].NING Pei Yong YU Ai Ping WANG Yuan GUO Li Ru SHAN Dan KONG Mei YU Ling Qi LYU Li Kun ZOU Ming SU Xu FEI Chun Nan ZHOU Yu Hui WANG Bai Qi 2020Biomedical and Environmental Sciences2020,33,10:2
8Kinetic Characteristics of Neutralizing Antibody Responses Vary among Patients with COVID-19显示文摘Objective The coronavirus disease 2019(COVID-19) pandemic continues to present a major challenge to public health. Vaccine development requires an understanding of the kinetics of neutralizing antibody(NAb) responses to severe acute respiratory syndrome coronavirus 2(SARS-CoV-2).Methods In total, 605 serum samples from 125 COVID-19 patients(from January 1 to March 14, 2020)varying in age, sex, severity of symptoms, and presence of underlying diseases were collected, and antibody titers were measured using a micro-neutralization assay with wild-type SARS-CoV-2.Results NAbs were detectable approximately 10 days post-onset(dpo) of symptoms and peaked at approximately 20 dpo. The NAb levels were slightly higher in young males and severe cases, while no significant difference was observed for the other classifications. In follow-up cases, the NAb titer had increased or stabilized in 18 cases, whereas it had decreased in 26 cases, and in one case NAbs were undetectable at the end of our observation. Although a decreasing trend in NAb titer was observed in many cases, the NAb level was generally still protective.Conclusion We demonstrated that NAb levels vary among all categories of COVID-19 patients. Longterm studies are needed to determine the longevity and protective efficiency of NAbs induced by SARS-CoV-2.LI Ling Hua TU Hong Wei LIANG Dan WEN Chun Yan LI An An LIN Wei Yin HU Ke Qi HONG Wen Shan LI Yue Ping SU Juan ZHAO San Tao LI Wei YUAN Run Yu ZHOU Ping Ping HU Feng Yu TANG Xiao Ping KE Chang Wen KE Bi Xia CAI Wei Ping 2021Biomedical and Environmental Sciences2021,34,12:1

10Recent advances in RNA structurome显示文摘RNA structures are essential to support RNA functions and regulation in various biological processes. Recently, a range of novel technologies have been developed to decode genome-wide RNA structures and novel modes of functionality across a wide range of species. In this review, we summarize key strategies for probing the RNA structurome and discuss the pros and cons of representative technologies. In particular, these new technologies have been applied to dissect the structural landscape of the SARS-CoV-2 RNA genome. We also summarize the functionalities of RNA structures discovered in different regulatory layers-including RNA processing, transport, localization, and mRNA translation-across viruses, bacteria, animals, and plants. We review many versatile RNA structural elements in the context of different physiological and pathological processes(e.g., cell differentiation, stress response, and viral replication). Finally, we discuss future prospects for RNA structural studies to map the RNA structurome at higher resolution and at the single-molecule and single-cell level, and to decipher novel modes of RNA structures and functions for innovative applications.Bingbing Xu Yanda Zhu Changchang Cao Hao Chen Qiongli Jin Guangnan Li Junfeng Ma Siwy Ling Yang Jieyu Zhao Jianghui Zhu Yiliang Ding Xianyang Fang Yongfeng Jin Chun Kit Kwok Aiming Ren Yue Wan Zhiye Wang Yuanchao Xue Huakun Zhang Qiangfeng Cliff Zhang Yu Zhou 2022Science China(Life Sciences)2022,65,7:1

12Effects of permanent left bundle branch area pacing on QRS duration and short-term cardiac function in pacing-indicated patients with left bundle branch block显示文摘In 1986,Burkhoff and Sagawa[1]observed that left ventricular pressure decreased linearly as the QRS duration(QRSd)increased in a pacing experiment.Subsequently,it became recognized that either left bundle branch block(LBBB)or right ventricular pacing could result in prolonged QRSd,with potential deleterious effects on cardiac function and increased risk of atrial fibrillation(AF),heart failure,and mortality.[2]Although previous clinical trials have demonstrated that patients with LBBB and heart failure could benefit from biventricular pacing(ie,biventricular cardiac resynchronization therapy[BiV-CRT]),30%to 40%of such patients do not respond to BiV-CRT and approximately an additional 10%of patients remain untreated owing to an unsuitable coronary sinus vein.With the development of appropriate implant tools,His bundle pacing(HBP)has become increasingly important to enhance pacing as an adjunctive therapy in heart failure treatment.Various studies have demonstrated that CRT utilizing HBP(His-CRT)may be valuable in patients with no response or failure to place a BiV-CRT.However,HBP has higher pacing threshold and lower R-wave amplitude shortcomings and cannot correct LBBB in patients with distal conduction system disease.Qi-Jun Shan Hai Xu Xiu-Juan Zhou Qing Chang Ling Ji Chun Chen Zhi-Xin Jiang 2021Chinese Medical Journal2021,,9:1

16A novel long-term intravenous combined with local treatment with human amnion-derived mesenchymal stem cells for a multidisciplinary rescued uremic calciphylaxis patient and the underlying mechanism显示文摘Calciphylaxis is a rare disease characterized histologically by microvessel calcification and microthrombosis,with high mortality and no proven therapy.Here,we reported a severe uremic calciphylaxis patient with progressive skin ischemia,large areas of painful malodorous ulcers,and mummified legs.Because of the worsening symptoms and signs refractory to conventional therapies,treatment with human amnion-derived mesenchymal stem cells(hAMSCs)was approved.Preclinical release inspections of hAMSCs,efficacy,and safety assessment,including cytokine secretory ability,immunocompetence,tumorigenicity,and genetics analysis in vitro,were introduced.We further performed acute and long-term hAMSC toxicity evaluations in C57BL/6 mice and rats,abnormal immune response tests in C57BL/6 mice,and tumorigenicity tests in neonatal Balbc-nu nude mice.After the preclinical research,the patient was treated with hAMSCs by intravenous and local intramuscular injection and external supernatant application to the ulcers.When followed up to 15 months,the blood-based markers of bone and mineral metabolism improved,with skin soft tissue regeneration and a more favorable profile of peripheral blood mononuclear cells.Skin biopsy after 1-month treatment showed vascular regeneration with mature noncalcified vessels within the dermis,and 20 months later,the re-epithelialization restored the integrity of the damaged site.No infusion or local treatment-related adverse events occurred.Thus,this novel long-term intravenous combined with local treatment with hAMSCs warrants further investigation as a potential regenerative treatment for uremic calciphylaxis due to effects of inhibiting vascular calcification,stimulating angiogenesis and myogenesis,anti-inflammatory and immune modulation,multidifferentiation,re-epithelialization,and restoration of integrity.Lianju Qin Jing Zhang Yujie Xiao Kang Liu Yugui Cui Fangyan Xu Wenkai Ren Yanggang Yuan Chunyan Jiang Song Ning Xiaoxue Ye Ming Zeng Hanyang Qian Anning Bian Fan Li Guang Yang Shaowen Tang Zhihong Zhang Juncheng Dai Jing Guo Qiang Wang Bin Sun Yifei Ge Chun Ouyang Xueqiang Xu Jing Wang Yaoyu Huang Hongqing Cui Jing Zhou Meilian Wang Zhonglan Su Yan Lu Di Wu Jingping Shi Wei Liu Li Dong Yinbing Pan Baiqiao Zhao Ying Cui Xueyan Gao Zhanhui Gao Xiang Ma Aiqin Chen Jie Wang Meng Cao Qian Cui Li Chen Feng Chen Youjia Yu Qiang Ji Zhiwei Zhang Mufeng Gu Xiaojun Zhuang Xiaolin Lv Hui Wang Yanyan Pan Ling Wang Xianrong Xu Jing Zhao Xiuqin Wang Cuiping Liu Ningxia Liang Changying Xing Jiayin Liu Ningning Wang 2022Journal of Molecular Cell Biology2022,14,2:1
17自来水中的药物:中国人类健康风险评估及监测建议框架显示文摘[背景]在世界范围内,已知药品会污染自来水,但是在中国尚无相关的人类健康风险评估。[目的]监测中国自来水中的32种药品,并评估暴露的终身人类健康风险,以便为未来的优先级管理和风险管理提供信息。[方法]作者分析来自13个城市的样本(n=113),并将检测到的浓度与现有或新得出的安全水平进行比较,以评估除产前期以外不同生命阶段的风险商数(RQs)。[结果]在89%的样本中检测到17种药品,大多数(92%)检出浓度<50ng/L。在≥20%的样本中检测到咖啡因(中等~最大浓度,24.4~564ng/L)、甲硝唑(1.8~19.3ng/L)、水杨酸(16.6~41.2ng/L)、氯贝酸(1.2~3.3ng/L)、卡马咪嗪(1.3~6.7ng/L)、二甲硝咪唑(6.9~14.7ng/L)。由于自来水中检测到药品水平及阳性频率均高,长江中下游地区城市和广州被视为受药品污染的重点区域。在检测到的17种药品中,13种为极低风险水平,但4种药品(二甲硝咪唑、甲砜霉素、磺胺二甲基嘧啶和克拉霉素)至少在一个生命阶段的RQ≥0.01,尤其是婴幼儿和儿童阶段,应被视为管理的高度优先级。本文提出了一个基于指标的监测框架,为中国的药品来源识别、水处理效果及水安全管理提供信息。[结论]中国的自来水是人体药品暴露另外的一个路径,特别是二甲硝咪唑,尽管基于当前的毒性数据,它对人体健康是低风险的。药品检测和监测建议框架可用于在中国和其他地方的水源保护和风险管理。Ho Wing Leung Ling Jin Si Wei Mirabelle Mei Po Tsui Bingsheng Zhou Liping Jiao Pak Chuen Cheung Yiu Kan Chun Margaret Burkhardt Murphy Paul Kwan Sing Lam 2013环境与职业医学2013,30,10:0
18SPAGINS:semiempirical parameterization for fragments in gamma-induced nuclear spallation显示文摘From the empirical phenomena of fragment distributions in nuclear spallation reactions,semiempirical formulas named SPAGINS were constructed to predict fragment cross-sections in high-energyγ-induced nuclear spallation reactions(PNSR).In constructing the SPAGINS formulas,theoretical models,including the TALYS toolkit,SPACS,and Rudstam formulas,were employed to study the general phenomenon of fragment distributions in PNSR with incident energies ranging from 100 to 1000 MeV.Considering the primary characteristics of PNSR,the SPAGINS formulas modify the EPAX and SPACS formulas and efficiently reproduce the measured data.The SPAGINS formulas provide a new and effective tool for predicting fragment production in PNSR.Hui‑Ling Wei Meng‑Die Zhou Pu Jiao Yu‑Ting Wang Jie Pu Kai‑Xuan Cheng Ya‑Fei Guo Chun‑Yuan Qiao Gong‑Tao Fan Hong‑Wei Wang Chun‑Wang Ma 2023Nuclear Science and Techniques2023,34,12:0
