1High-accuracy primary and transfer standards for radiometric calibration显示文摘The first research and experimental results obtained in China of high-accuracy radiometric calibration based on cryogenic radiometer are reported. Uncertainties of cryogenic radiometer and trap detectors at 7 wavelengths in the visible spectrum (488-786 nm) were less than 0.023% and 0.035% respectively, which proved the reasonability and possibility of establishing and transferring high-accuracy radiometric standards based on detectors.Xiaobing Zheng Haoyu Wu Junping Zhang Yucheng Liu Wei Zhou Leyi Wang Yanli Qiao 2000Chinese Science Bulletin2000,45,21:12
2Comparative Analysis of Three Types of Peaches:Identification of the Key Individual Characteristic Flavor Compounds by Integrating Consumers' Acceptability with Flavor Quality显示文摘In order to recognize the key flavor compounds influencing the consumers' choice for honey peach, nectarine, and flat peach and provide important information for orientation breeding, sugars, organic acids, and aroma volatiles in 3 types of peaches were examined by high performance liquid chromatography(HPLC) and gas chromatography–mass spectrometry(GC–MS) and their key individual characteristic flavor compounds were identified by multivariate analysis integrated with consumers' evaluation. No significant differences in sugar and organic acid were observed between 3 types of peaches. In hierarchical clustering analysis(HCA) and principal component analysis(PCA)models, 3 types of peaches could not be differentiated by sugars or organic acids, but could be identified completely by aroma volatiles or by flavor compounds. A partial least squares regression(PLSR) model revealed that the key individual characteristic volatiles in nectarine, honey peach, and flat peach are C9 compounds and terpenic compounds, norisoprenoids and C6 compounds, and benzaldehyde, γ-decalactone, andδ-dodecalactone, respectively. These results suggest that sugars and organic acids form the background flavor of peach fruit and lactones shape the typical peach aroma. However, the individual aroma volatiles play the decisive role in unique flavor determination of different types of peaches.XI Wanpeng ZHENG Qiao LU Juanfang QUAN Junping 2017Horticultural Plant Journal2017,3,1:8
3Long- versus short-interval follow-up after resection of hepatocellular carcinoma: a retrospective cohort study显示文摘Background:Average postoperative follow-up intervals vary in patients undergoing hepatocellular carcinoma(HCC)resection because of limited evidence regarding the optimal interval.We aimed to compare the associations of long-versus short-interval follow-up with survival and recurrence in risk-stratified HCC patients.Methods:We performed a retrospective cohort study between 2007 and 2014.In total,1227 patients treated by curative resection of Barcelona Clinic Liver Cancer stage A or B HCC were stratified as having a low(n=865)or high(n=362)risk of early recurrence(within the first 2 years after resection)based on prognostic factors identified by the least absolute shrinkage and selection operation algorithm.Patients were further classified into long-interval(every 4-6 months)and short-interval(every 2-4 months)follow-up subgroups based on follow-up within 2 years after resection(low risk,long vs.short:n=390 vs.n=475;high-risk,long vs.short:n=149 vs.n=213).Results:The short-interval follow-up did not prolong overall survival in either the low-risk(hazard ratio[HR]=1.152;95%confidence interval[CI]0.720-1.843)or high-risk(HR=1.213;95%CI 0.702-2.094)patients.Early recurrence occurred in 401 patients.For high-risk patients,the short-interval follow-up subgroup exhibited smaller intrahepatic recurrence than did the long-interval group(2.6 vs.3.5 cm,respectively,P=0.045).However,no significant difference in the rate of Barcelona Clinic Liver Cancer stage 0/A recurrence was found between the long-and short-interval follow-up groups in either low-or high-risk patients(63.1%vs.68.2%,respectively,P=0.580;31.3%vs.41.5%,respec-tively,P=0.280).The rate of curative intent treatment for recurrence(34.5%vs.39.7%,respectively,P=0.430;14.6%vs.20.3%,respectively,P=0.388)was also similar between the follow-up groups for low-and high-risk patients.Conclusions:Shortening the postoperative follow-up interval from every 4-6 months to every 2-4 months within the first 2 years after resection did not increase the rate of curative intent treatment or prolong the overall survival of patients with Barcelona Clinic Liver Cancer stage A or B HCC.Wei He Yun Zheng Ruhai Zou Jingxian Shen Junping Yang Jiliang Qiu Qiang Tao Wenwu Liu Zhiwen Yang Yuanping Zhang Binkui Li Yunfei Yuan 2018Cancer Communications2018,38,1:2
4Robust, healable and hydrophobically recoverable polydimethylsiloxane based supramolecular material with dual-activate hard segment显示文摘In this paper, a novel dual-activate hard segment strategy is proposed for the fabrication of polydimethylsiloxane(PDMS) based supramolecular polymer(PDMS-PDITC-IPDI). The unique design endows the PDMS-PDITC-IPDI with high toughness(43.1–24.5 MJ/m^(3)), tensile strength(11.3–6.6 MPa) and elongation at break(730%–615%), and the mechanical properties and dynamic property can be regulated by varying degrees of hard segment activation. Moreover, the PDMS-PDITC-IPDI polymers exhibit excellent self-recovery property during successive loading-unloading processes. Additionally, both wettability damage caused by O2 plasma treatment and mechanical damage can be healed by simple heating, showing good hydrophobic recovery and selfhealability. Taking advantages of merits of the PDMS-PDITC-IPDI, the applications of the material as recyclable adhesive and 3D printing material are also investigated.LV Chi QI YuHao HU RuoFei ZHENG JunPing 2021Science China(Technological Sciences)2021,64,2:2

6An Azo-PDMS-based wearable UV sensor with the optimized photo response mode for dual sensing and synchronous detection显示文摘A wearable UV sensor is designed to realize UV detection and a warning effect on people’s excessive UV exposure.It is noteworthy that the photoelectric system and supporting material of the most conventional sensor are separated.The unstable connection between the two components and the complicated construction method makes the sensor susceptible to external motion interference and prone to failure.Herein,we developed a unique photo response mode of the UV sensor based on a novel photo responsive material.An azobenzene-containing polydimethylsiloxane(Azo-PDMS)film was prepared as the outer layer of the sensor.It integrated the functions of photo response source,support and protection,which realized the direct contact and rapid response to the UV light source.Carbon nanotube(CNT),wrapped in the middle of Azo-PDMS films as an inner layer,transformed the photomechanical response signal into the photoelectric signal.The photo response mode endows the sensor with excellent anti-motion interference capabilities and a true sense of UV-strain synchronous monitoring performance,which is of great significance to the practical application of wearable devices.In addition,based on the excellent properties of Azo-PDMS,the sensor can also protect the human body from UV damage,self-repair after fracture,and realize personalized customization through 3 D printing.It makes a breakthrough in the design and construction of wearable UV sensors and paves a new way to optimize sensor photo response modes.QI YuHao ZHENG JunPing 2022Science China(Technological Sciences)2022,65,1:2

8Tenofovir disoproxil fumarate therapy in patients with chronic hepatitis B and advanced fibrosis or compensated cirrhosis显示文摘Background and aims:Tenofovir disoproxil fumarate(TDF)is the first-line therapy for chronic hepatitis B.This interim analysis presents the efficacy and safety data for TDF at Week 144 in patients with chronic hepatitis B and advanced fibrosis or compensated cirrhosis from China.Methods:Patients were assessed for incidence of newly diagnosed hepatocellular carcinoma(HCC)and disease progression,liver stiffness measurement(LSM),virological suppression(serum hepatitis B virus DNA<20 IU/mL),alanine aminotransferase normalization,hepatitis B e antigen(HBeAg)loss and seroconversion,histological liver fibrosis score,and safety at Week 144.Results:Overall,197 patients were enrolled.At Week 144,the incidence of newly diagnosed HCC was observed in 2.1%patients,and the incidence of disease progression was observed in 3.6%patients.The mean(standard deviation)change in LSM from baseline was5.1(5.85)kPa.Serum hepatitis B virus DNA<20 IU/mL was observed in 94.1%patients,alanine aminotransferase normalization in 33.5%patients,HBeAg loss in 35.6%patients,and HBeAg seroconversion in 14.4%patients.Among patients with stage F3 or F4 fibrosis at baseline by LSM,38.3%patients regressed to stage F0/1,and 22.0%of patients regressed to stage F2 at Week 144.Overall,67.7%patients experienced≥1 adverse events,13.8%patients experienced TDF-related adverse events,and 16.4%patients experienced serious(none were TDF-related).Conclusions:At Week 144 of TDF treatment,low incidence of HCC and disease progression were reported.Virological suppression was observed in 94.1%patients,which was associated with fibrosis regression.No new safety events were identified.Huiying Rao Jia Shang Qing Xie Jianqi Lian Pujun Gao Junping Shi Xinyue Chen Jiefei Wang Min Xu Liaoyun Zhang Yingren Zhao QingMao Maorong Wang Wei Zhao Zong Zhang Jidong Jia Hong Tang Jiming Zhang Xin Zheng Chang Liu Lai Wei 2022iLIVER2022,1,3:1
9A novel radiomics signature based on T2-weighted imaging accurately predicts hepatic inflammation in individuals with biopsy-proven nonalcoholic fatty liver disease:a derivation and independent validation study显示文摘Background:Currently,there are no effective methods for assessing hepatic inflammation without resorting to histological examination of liver tissue obtained by biopsy.T2-weighted images(T2WI)are routinely obtained from liver magnetic resonance imaging(MRI)scan sequences.We aimed to establish a radiomics signature based on T2WI(T2-RS)for assessment of hepatic inflammation in people with nonalcoholic fatty liver disease(NAFLD).Methods:A total of 203 individuals with biopsy-confirmed NAFLD from two independent Chinese cohorts with liver MRI examination were enrolled in this study.The hepatic inflammatory activity score(IAS)was calculated by the unweighted sum of the histologic scores for lobular inflammation and ballooning.One thousand and thirty-two radiomics features were extracted from the localized region of interest(ROI)in the right liver lobe of T2WI and,subsequently,selected by minimum redundancy maximum relevance and least absolute shrinkage and selection operator(LASSO)methods.The T2-RS was calculated by adding the selected features weighted by their coefficients.Results:Eighteen radiomics features from Laplacian of Gaussian,wavelet,and original images were selected for establishing T2-RS.The T2-RS value differed significantly between groups with increasing grades of hepatic inflammation(P<0.01).The T2-RS yielded an area under the receiver operating characteristic(ROC)curve(AUROC)of 0.80[95%confidence interval(CI):0.71-0.89]for predicting hepatic inflammation in the training cohort with excellent calibration.The AUROCs of T2-RS in the internal cohort and external validation cohorts were 0.77(0.61-0.93)and 0.75(0.63-0.84),respectively.Conclusions:The T2-RS derived from radiomics analysis of T2WI shows promising utility for predicting hepatic inflammation in individuals with NAFLD.Zhong-Wei Chen Huan-Ming Xiao Xinjian Ye Kun Liu Rafael S.Rios Kenneth I.Zheng Yi Jin Giovanni Targher Christopher D.Byrne Junping Shi Zhihan Yan Xiao-Ling Chi Ming-Hua Zheng 2022Hepatobiliary Surgery and Nutrition2022,11,2:1
10An international Delphi consensus statement on metabolic dysfunction-associated fatty liver disease and risk of chronic kidney disease显示文摘Background:With the rising global prevalence of fatty liver disease related to metabolic dysfunction,the association of this common liver condition with chronic kidney disease(CKD)has become increasingly evident.In 2020,the more inclusive term metabolic dysfunction-associated fatty liver disease(MAFLD)was proposed to replace the term non-alcoholic fatty liver disease(NAFLD).The observed association between MAFLD and CKD and our understanding that CKD can be a consequence of underlying metabolic dysfunction support the notion that individuals with MAFLD are at higher risk of having and developing CKD compared with those without MAFLD.However,to date,there is no appropriate guidance on CKD in individuals with MAFLD.Furthermore,there has been little attention paid to the link between MAFLD and CKD in the Nephrology community.Methods and Results:Using a Delphi-based approach,a multidisciplinary panel of 50 international experts from 26 countries reached a consensus on some of the open research questions regarding the link between MAFLD and CKD.Conclusions:This Delphi-based consensus statement provided guidance on the epidemiology,mechanisms,management and treatment of MAFLD and CKD,as well as the relationship between the severity of MAFLD and risk of CKD,which establish a framework for the early prevention and management of these two common and interconnected diseases.Dan-Qin Sun Giovanni Targher Christopher D.Byrne David C.Wheeler Vincent Wai-Sun Wong Jian-Gao Fan Herbert Tilg Wei-Jie Yuan Christoph Wanner Xin Gao Michelle T.Long Mehmet Kanbay Mindie H.Nguyen Sankar D.Navaneethan Yusuf Yilmaz Yuli Huang Rino A.Gani Pierluigi Marzuillo Jérôme Boursier Huijie Zhang Chan-Young Jung Jin Chai Luca Valenti George Papatheodoridis Giovanni Musso Yu-Jun Wong Mohamed El-Kassas Nahum Méndez-Sánchez Silvia Sookoian Michael Pavlides Ajay Duseja Adriaan G.Holleboom Junping Shi Wah-Kheong Chan Yasser Fouad Junwei Yang Sombat Treeprasertsuk Helena Cortez-Pinto Masahide Hamaguchi Manuel Romero-Gomez Mamun Al Mahtab Ponsiano Ocama Atsushi Nakajima Chunsun Dai Mohammed Eslam Lai Wei Jacob George Ming-Hua Zheng 2023Hepatobiliary Surgery and Nutrition2023,12,3:1

13Immune‑Ageing Evaluation of Peripheral T and NK Lymphocyte Subsets in Chinese Healthy Adults显示文摘Ageing is often accompanied with a decline in immune system function,resulting in immune ageing.Numerous studies have focussed on the changes in different lymphocyte subsets in diseases and immunosenescence.The change in immune phenotype is a key indication of the diseased or healthy status.However,the changes in lymphocyte number and phenotype brought about by ageing have not been comprehensively analysed.Here,we analysed T and natural killer(NK)cell subsets,the phenotype and cell differentiation states in 43,096 healthy individuals,aged 20–88 years,without known diseases.Thirty-six immune parameters were analysed and the reference ranges of these subsets were established in different age groups divided into 5-year intervals.The data were subjected to random forest machine learning for immune-ageing modelling and confirmed using the neural network analysis.Our initial analysis and machine modelling prediction showed that na.ve T cells decreased with ageing,whereas central memory T cells(Tcm)and effector memory T cells(Tem)increased cluster of differentiation(CD)28-associated T cells.This is the largest study to investigate the correlation between age and immune cell function in a Chinese population,and provides insightful differences,suggesting that healthy adults might be considerably influenced by age and sex.The age of a person's immune system might be different from their chronological age.Our immune-ageing modelling study is one of the largest studies to provide insights into‘immune-age’rather than‘biological-age’.Through machine learning,we identified immune factors influencing the most through ageing and built a model for immune-ageing prediction.Our research not only reveals the impact of age on immune parameter differences within the Chinese population,but also provides new insights for monitoring and preventing some diseases in clinical practice.Zhenghu Jia Zhiyao Ren Dongmei Ye Jiawei Li Yan Xu Hui Liu Ziyu Meng Chengmao Yang Xiaqi Chen Xinru Mao Xueli Luo Zhe Yang Lina Ma Anyi Deng Yafang Li Bingyu Han Junping Wei Chongcheng Huang Zheng Xiang Guobing Chen Peiling Li Juan Ouyang Peisong Chen Oscar Junhong Luo Yifang Gao Zhinan Yin 2023Phenomics2023,3,4:1

19Design of a search and rescue terminal based on the dual-mode satellite and CDMA network显示文摘The current goal is to create a set of portable terminals with GPS/BD2 dual-mode satellite positioning, vital signs monitoring and wireless transmission functions. The terminal depends on an ARM processor to collect and combine data related to vital signs and GPS/BD2 location information, and sends the message to headquarters through the military CDMA network. It integrates multiple functions as a whole. The satellite positioning and wireless transmission capabilities are integrated into the motherboard, and the vital signs sensors used in the form of belts communicate with the board through Bluetooth. It can be adjusted according to the headquarters' instructions. This kind of device is of great practical significance for operations during disaster relief, search and rescue of the wounded in wartime, non-war military operations and other special circumstances.ZHAO JunPing 1* , ZHANG Xuan 2 , ZHENG Bing 1 , ZHOU YuBin 3 , SONG Hao 2 , SONG Wei 2 , ZHANG MeiKui 1 , LIU TongZe 1 & ZHOU Li 1 1 Institute of Medical Informatics, General Hospital of PLA, Beijing 100853, China 2 Beijing Aerospace Science & Industry Century Satellite Hi-Tech Co.

20肝癌切除术后的长间隔与短间隔随访:一项回顾性队列研究显示文摘背景与目的由于缺乏证据证明肝细胞癌(hepatocellular carcinoma,HCC)切除术后的最佳随访间隔,术后患者接受随访的平均时间间隔不同。我们的目的是比较长间隔随访和短间隔随访与生存和复发的相关性在不同风险分层肝癌患者中的差异。方法我们在2007年至2014年期间进行了一项回顾性队列研究。共有1227例巴塞罗那临床肝癌分期A期或B期的患者接受了根治性切除术。根据最小绝对收缩和选择操作算法为基础的预后因素分析,我们将患者分层为有低风险(n=865)或高风险(n=362)早期复发(切除术后2年内)的2组。根据切除术后2年内的随访情况,患者进一步分为长间隔(每4–6个月)随访和短期间隔(每2–4个月)随访的亚组(低风险,长期vs.短期:n=390 vs. n=475;高风险,长期vs.短期:n=149 vs. n=213)。结果不管在低风险[风险比(hazard ratio,HR)=1.152;95%置信区间(confidenceinterval,CI):0.720–1.843]还是高风险(HR=1.213;95%CI:0.702–2.094)患者中,短间隔随访没有延长患者的总生存期。401例患者出现早期复发。在高风险患者中,与长间隔随访组相比,短间隔组肝内复发肿瘤较小(2.6 cm vs. 3.5 cm,P=0.045)。但是,对于巴塞罗临床肝癌分期0/A期,长间隔与短间隔随访不管在低风险还是高风险患者中复发率(63.1%vs. 68.2%,P=0.580;31.3%vs. 41.5%,P=0.280)差异均无统计学意义。类似的,根治性切除术后,长间隔或短间隔随访分别在低风险和高风险患者中的复发率(34.5%vs. 39.7%,P=0.430;14.6%vs. 20.3%,P=0.388)差异也均无统计学意义。结论对于巴塞罗那临床肝癌分期A期或B期的患者,在接受了根治性切除术后的前2年内,将随访时间从4–6月缩短为2–4个月并不能增加根治性切除术的成功率或延长患者生存时间。Wei He Yun Zheng Ruhai Zou Jingxian Shen Junping Yang Jiliang Qiu Qiang Tao Wenwu Liu Zhiwen Yang Yuanping Zhang Binkui Li Yunfei Yuan 2018癌症2018,37,12:0
