4Ciliary parathyroid hormone signaling activates transforming growth factor-βto maintain intervertebral disc homeostasis during aging显示文摘Degenerative disc disease(DDD) is associated with intervertebral disc degeneration of spinal instability. Here, we report that the cilia of nucleus pulposus(NP) cells mediate mechanotransduction to maintain anabolic activity in the discs. We found that mechanical stress promotes transport of parathyroid hormone 1 receptor(PTH1 R) to the cilia and enhances parathyroid hormone(PTH) signaling in NP cells. PTH induces transcription of integrin α_vβ_6 to activate the transforming growth factor(TGF)-β-connective tissue growth factor(CCN2)-matrix proteins signaling cascade. Intermittent injection of PTH(iPTH) effectively attenuates disc degeneration of aged mice by direct signaling through NP cells, specifically improving intervertebral disc height and volume by increasing levels of TGF-β activity, CCN2, and aggrecan. PTH1 R is expressed in both mouse and human NP cells. Importantly,knockout PTH1 R or cilia in the NP cells results in significant disc degeneration and blunts the effect of PTH on attenuation of aged discs. Thus, mechanical stress-induced transport of PTH1 R to the cilia enhances PTH signaling, which helps maintain intervertebral disc homeostasis, particularly during aging, indicating therapeutic potential of iPTH for DDD.Liwei Zheng Yong Cao Shuangfei Ni Huabin Qi Zemin Ling Xin Xu Xuenong Zou Tianding Wu Ruoxian Deng Bo Hu Bo Gao Hao Chen Yusheng Li Jianxi Zhu Francis Tintani Shadpour Demehri Amit Jain Khaled M.Kebaish Shenghui Liao Cheryle A.Séguin Janet L.Crane Mei Wan Hongbin Lu Paul D.Sponseller Lee H.RileyIII Xuedong Zhou Jianzhong Hu Xu Cao 2018Bone Research2018,6,3:13

6A resistin binding peptide selected by phage display inhibits 3T3-L1 preadipocyte differentiation显示文摘Background Resistin, a newly discovered cysteine-rich hormone secreted mainly by adipose tissues, has been proposed to form a biochemical link between obesity and type 2 diabetes. However, the resistin receptor has not yet been identified. This study aimed to identify resistin binding proteins/receptor. Methods Three cDNA fragments with the same 11 bp 5’ sequence were found by screening a cDNA phage display library of rat multiple tissues. As the reading frames of the same 11 bp 5’ sequence were interrupted by a TGA stop codon, plaque lift assay was consequently used to prove the readthrough phenomenon. The stop codon in the same 11 bp 5’ sequence was replaced by tryptophan, and the binding activity of the coded peptide [AWIL, which was designated as resistin binding peptide (RBP)] with resistin was identified by the confocal microscopy technique and the affinity chromatography experiment. pDual GC-resistin and pDual GC-resistin binding peptide were co-transfected into 3T3-L1 cells to confirm the function of resistin binding peptide. Results Three cDNA fragments with the same 11 bp 5’ sequence were found. The TGA stop codon in reading frames of the same 11 bp 5’ sequence was proved to be readthroughed. The binding activity of RBP with resistin was consequently identified. The expression of the resistin binding peptide in 3T3-L1 preadipocytes expressing pDual GC-resistin significantly inhibited the adipogenic differentiation. Conclusion RBP could effectively rescue the promoted differentiation of resistin overxepressed 3T3-L1 preadipocyte.LIU Feng GUO Xi-rong GONG Hai-xia NI Yu-hui FEI Li PAN Xiao-qin GUO Mei CHEN Rong-hua 2006Chinese Medical Journal2006,,6:12
7Biomechanical comparison of locking plate and crossing metallic and absorbable screws fixations for intra-articular calcaneal fractures显示文摘The locking plate and percutaneous crossing metallic screws and crossing absorbable screws have been used clinically to treat intra-articular calcaneal fractures, but little is known about the biomechanical differences between them. This study compared the biomechanical stability of calcaneal fractures fixed using a locking plate and crossing screws. Three-dimensional finite-element models of intact and fractured calcanei were developed based on the CT images of a cadaveric sample. Surgeries were simulated on models of Sanders type III calcaneal fractures to produce accurate postoperative models fixed by the three implants. A vertical force was applied to the superior surface of the subtalar joint to simulate the stance phase of a walking gait. This model was validated by an in vitro experiment using the same calcaneal sample. The intact calcaneus showed greater stiffness than the fixation models. Of the three fixations, the locking plate produced the greatest stiffness and the highest von Mises stress peak. The micromotion of the fracture fixated with the locking plate was similar to that of the fracture fixated with the metallic screws but smaller than that fixated with the absorbable screws. Fixation with both plate and crossing screws can be used to treat intra-articular calcaneal fractures. In general, fixation with crossing metallic screws is preferable because it provides sufficient stability with less stress shielding.Ming Ni Duo Wai-Chi Wong Jiong Mei Wenxin Niu Ming Zhang 2016Science China(Life Sciences)2016,59,9:11
8Exosomes: roles and therapeutic potential in osteoarthritis显示文摘Exosomes participate in many physiological and pathological processes by regulating cell–cell communication, which are involved in numerous diseases, including osteoarthritis(OA). Exosomes are detectable in the human articular cavity and were observed to change with OA progression. Several joint cells, including chondrocytes, synovial fibroblasts, osteoblasts, and tenocytes, can produce and secrete exosomes that influence the biological effects of targeted cells. In addition, exosomes from stem cells can protect the OA joint from damage by promoting cartilage repair, inhibiting synovitis, and mediating subchondral bone remodeling.This review summarizes the roles and therapeutic potential of exosomes in OA and discusses the perspectives and challenges related to exosome-based treatment for OA patients in the future.Zhenhong Ni Siru Zhou Song Li Liang Kuang Hangang Chen Xiaoqing Luo Junjie Ouyang Mei He Xiaolan Du Lin Chen 2020Bone Research2020,8,2:10
9Glycylproline dipeptidyl aminopeptidase isoenzyme in diagnosis of primary hepatocellular carcinoma显示文摘AIM: To investigate the role of glycylproline dipeptidyl aminopeptidase (GPDA) isoenzyme in the diagnosis of primary hepatocellular carcinoma (PHC), especially in patients with negative alpha-fetoprotein (AFP).METHODS: A stage gradient polyacrylamide gel discontinuous electrophoresis system was developed to separate serum GPDA isoenzymes, which were determined in 102 patients with PHC, 45 cases with liver cirrhosis, 24cases with chronic hepatitis, 35 cases with benign liver spaceoccupying lesions, 20 cases with metastatic liver cancer and 50 cases with extra-hepatic cancer, as well as 80 healthy subjects. The relationships between GPDA isoenzymes and AFP, the sizes of tumors, as well as alanine aminotransferase (ALT) were also analyzed.RESULTS: Serum GPDA was separated into two isoenzymes,GPDA-S and GPDA-F. The former was positive in all subjects,while the latter was found mainly in majority of PHC (85.3 %)and a few cases with liver cirrhosis (11.1%), chronic hepatitis (33.3 %), metastatic liver cancer (15.0 %) and non-hepatic cancer (16.0 %). GPDA-F was negative in all healthy subjects and patients with benign liver space-occupying lesions,including abscess, cysts and angioma. There was no correlation between GPDA-F and AFP concentration or tumor size. GPDA-F was consistently positive and not correlated with ALT in PHC, but GPDA-F often converted to negative as decline of ALT in benign liver diseases. The electrophoretic migration of GPDA-F became sluggish after the treatment of neuraminidase.CONCLUSION: GPDA-F is a new useful serum marker for PHC. Measurement of serum GPDA-F is helpful in diagnosis of PHC, especially in patients with negative AFP. GPDA-F is one kind of glycoproteins rich in sialic acid.Run-Zhou Ni Jie-Fei Huang Ming-Bing Xiao Mei Li Xian-Yong Meng Department of Gastroenterology,Affiliated Hospital of Nantong Medical College,Nantong 226001,Jiangsu Province,China 2003World Journal of Gastroenterology2003,9,4:10
10The 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 2022Science China(Physics,Mechanics & Astronomy)2022,65,8:7
11Molecular Characterization and Correlation with β-lactam Resistance of Streptococcus pneumonia Isolates in Hangzhou,China显示文摘Penicillin-binding proteins(PBPs) are the target of β-lactam antibiotics(the major treatment for Streptococcus pneumoniae infections),and mutations in PBPs are considered as a primary mechanism for the development of β-lactam resistance in S.pneumoniae.This study was conducted to investigate the mutations in the PBPs of clinical S.pneumoniae isolates in Hangzhou,China,in correlation with β-lactam resistance.Results showed that 19 F was the predominant serotype(7/27) and 14 of the S.pneumoniae isolates were resistant to both penicillin G and cephalosporin.Genotyping results suggested that β-lactam-resistant isolates primarily exhibited single-site mutations in both the STMK and SRNVP motifs of pbp1 a in combination with double-site mutations in the STMK motif of pbp2 x,which might be the primary mechanisms underlying the β-lactam resistance of the isolates in this study.chu mei fen liu xiao xiang zhang shao ni huang yan ying du peng wang li fang ji lei yan jie sun ai hua 2018Biomedical and Environmental Sciences2018,31,5:7
12No expenditure difference among patients with liver cancer at stageⅠ-ⅣV:Findings from a multicenter cross-sectional study in China显示文摘Objective:The number of liver cancer patients in China accounts for more than half of the world.However,China currently lacks national,multicenter economic burden data,and meanwhile,measuring the differences among different subgroups will be informative to formulate corresponding policies in liver cancer control.Thus,the aim of the study was to measure the economic burden of liver cancer by various subgroups.Methods:A hospital-based,multicenter and cross-sectional survey was conducted during 2012・2014,covering 39 hospitals and 21 project sites in 13 provinces across China.The questionnaire covers clinical information,sociology,expenditure,and related variables.All expenditure data were reported in Chinese Yuan(CNY)using 2014 values.Results:A total of 2,223 liver cancer patients were enrolled,of whom 59.61%were late-stage cases(III-IV),and 53.8%were hepatocellular carcinoma.The average total expenditure per liver cancer patient was estimated as 53,220 CNY,including 48,612 CNY of medical expenditures(91.3%)and 4,608 CNY of non-medical expenditures(8.7%).The average total expenditures in stage I,H,m and stage IV were 52,817 CNY,50,877 CNY,50,678 CNY and 54,089 CNY(P>0.05),respectively.Non-medical expenditures including additional meals,additional nutrition care,transportation,accommodation and hired informal nursing were 1,453 CNY,839 CNY,946 CNY,679 CNY and 200 CNY,respectively.The one-year out-of-pocket expenditure of a newly diagnosed patient was 24,953 CNY,and 77.2%of the patients suffered an unmanageable financial burden.Multivariate analysis showed that overall expenditure differed in almost all subgroups(P<0.05),except for sex,clinical stage,and pathologic type.Conclusions:There was no difference in treatment expenditure for liver cancer patients at different clinical stages,which suggests that maintaining efforts on treatment efficacy improvement is important but not enough.To fiirtherly reduce the overall economic burden from liver cancer,more effort should be given to primary and secondary prevention strategies.Haike Lei Lin Lei Jufang Shi Yongzhong Wu Ling Liang Huiyao Huang Mei He Fangzhou Bai Maomao Cao Hui Qiu Yuting Wang Chengcheng Liu Jia Du Hong Wang Yan Zhang Mengdi Cao Ji Peng Ni Li Chunfeng Qu Min Dai Wanqing Chen Jie He 2020Chinese Journal of Cancer Research2020,32,4:7
13Validation of the China-PAR Equations for Cardio-cerebrovascular Risk Prediction in the Inner Mongolian Population显示文摘The objective of this study was to evaluate the usefulness of the China-PAR equations in predicting the 10-year risk of cardiovascular disease(CVD) in the Inner Mongolians population. A population-based, prospective cohort of 2,589 Mongolians were followed up from 2003 to 2012.Participants were categorized into 4 subgroups according to their 10-year CVD risks calculated using the China-PAR equations: < 5%, 5%-9.9%,10%-19.9%, and ≥ 20%. The China-PAR equations discriminated well with good C statistics(range,0.76-0.86). The adjusted hazard ratios for CVD showed an increasing trend among the 4 subgroups(P for trend < 0.01). However, the China-PAR equations underestimated the 10-year CVD risk in Mongolians, and the calibration was unsatisfactory(Hosmer-Lemeshow χ~2 = 19.98, P < 0.01 for men, χ~2 = 46.58, P < 0.001 for women). The performance of the China-PAR equations warrants further validation in other ethnic groups in China.ZENG Ni Mei ZHENG Xiao Wei PENG Hao JIAO Yang LI Hong Mei ZHANG Ming Zhi WANG Ai Li ZHANG Yong Hong 2018Biomedical and Environmental Sciences2018,31,6:6
14Effect of Sheng Xue Ning Tablets on Renal Anemia in Patients Subject to Maintenance Hemodialysis and Safety Evaluation: A Multi-setting Prospective Randomized Study显示文摘This study compared Sheng Xue Ning(SXN)tablets with ferrous succinate(FS)tablets in terms of their efficacy for the treatment of iron-deficient renal anemia and safety in patients subject to maintenance hemodialysis(MHD).A total of 94 patients undergoing MHD were randomly assigned to an experiment group(receiving oral SXN tablcts,SXN group)and a control group(orally given FS tablets,FS group)and followed up for 12 weeks.Erythropoietin(EPO)was used in both groups.The eficacy was assessed by detecting the subsequent changes in hemoglobin(Hb),serum iron(SI),SF and transferrin saturation(TSAT).At the 12th week,Hb and TSAT levels in both groups were significantly increased compared to those in the screening period(P<0.05).However,no significant difference in Hb and TSAT was found between the two groups.The average weekly EPO dosage used was lower in SXN group than in FS group(P<0.05)at the 10th week and the 12th week.Our study showed that SXN tablets can effectively ameliorate renal anemia and keep iron metabolism stable in MHD patients,and its efficacy is virtually close to that of FS tablets.Meanwhile,SXN tablets can reduce the dosage of EPO and have a good safety profile.Xiao-jing TANG Shu RONG Chang-lin MEI Zhao-hui NI Geng-ru JIANG Wei-jie YUAN Nian-song WANG Zhi-yong GUO Jun MA Hai-dong YAN Li-ming ZHANG 2020Current Medical Science2020,40,2:5
15Impact of proton pump inhibitors on clinical outcomes in patients after acute myocardial infarction: a propensity score analysis from China Acute Myocardial Infarction(CAMI) registry显示文摘Background Proton pump inhibitors(PPIs) are recommended by the latest guidelines to reduce the risk of bleeding in acute myocardial infarction(AMI) patients treated with dual antiplatelet therapy(DAPT). However, previous pharmacodynamic and clinical studies have reported controversial results on the interaction between PPI and the P2 Y12 inhibitor clopidogrel. We investigated the impact of PPIs use on in-hospital outcomes in AMI patients, aiming to provide a new insight on the value of PPIs. Methods A total of 23,380 consecutive AMI patients who received clopidogrel with or without PPIs in the China Acute Myocardial Infarction(CAMI) registry were analyzed. The primary endpoint was major adverse cardiovascular and cerebrovascular events(MACCE) defined as a composite of in-hospital cardiac death, re-infarction and stroke. Propensity score matching(PSM) was used to control potential baseline confounders. Multivariate logistic regression analysis was performed to evaluate the effect of PPIs use on MACCE and gastrointestinal bleeding(GIB). Results Among the whole AMI population, a large majority received DAPT and 67.5% were co-medicated with PPIs. PPIs use was associated with a decreased risk of MACCE(Before PSM OR: 0.857, 95% CI: 0.742-0.990, P = 0.0359;after PSM OR: 0.862, 95% CI: 0.768-0.949, P = 0.0245) after multivariate adjustment. Patients receiving PPIs also had a lower risk of cardiac death but a higher risk of complicating with stroke. When GIB occurred, an alleviating trend of GIB severity was observed in PPIs group. Conclusions Our study is the first nation-wide large-scale study to show evidence on PPIs use in AMI patients treated with DAPT. We found that PPIs in combination with clopidogrel was associated with decreased risk for MACCE in AMI patients, and it might have a trend to mitigate GIB severity. Therefore, PPIs could become an available choice for AMI patients during hospitalization.Wen-Ce SHI Si-De GAO Jin-Gang YANG Xiao-Xue FAN Lin NI Shu-Hong SU Mei YU Hong-Mei YANG Meng-Yue YU Yue-Jin YANG 2020Journal of Geriatric Cardiology2020,17,11:5

17Phyllotaxis-inspired nanosieves with multiplexed orbital angular momentum显示文摘Nanophotonic platforms such as metasurfaces,achieving arbitrary phase profiles within ultrathin thickness,emerge as miniaturized,ultracompact and kaleidoscopic optical vortex generators.However,it is often required to segment or interleave independent sub-array metasurfaces to multiplex optical vortices in a single nano-device,which in turn affects the device’s compactness and channel capacity.Here,inspired by phyllotaxis patterns in pine cones and sunflowers,we theoretically prove and experimentally report that multiple optical vortices can be produced in a single compact phyllotaxis nanosieve,both in free space and on a chip,where one meta-atom may contribute to many vortices simultaneously.The time-resolved dynamics of on-chip interference wavefronts between multiple plasmonic vortices was revealed by ultrafast time-resolved photoemission electron microscopy.Our nature-inspired optical vortex generator would facilitate various vortex-related optical applications,including structured wavefront shaping,free-space and plasmonic vortices,and high-capacity information metaphotonics.Zhongwei Jin David Janoschka Junhong Deng Lin Ge Pascal Dreher Bettina Frank Guangwei Hu Jincheng Ni Yuanjie Yang Jing Li Changyuan Yu Dangyuan Lei Guixin Li Shumin Xiao Shengtao Mei Harald Giessen Frank Meyer zu Heringdorf Cheng-Wei Qiu 2021eLight2021,1,1:3
18A novel decomposition and coordination algorithm for complex networks and its application to power grids显示文摘To analyze and control complex networks effectively, this paper puts forward a new kind of scheme, which takes control separately in each area and can achieve the network’s coordinated optimality. The proposed algorithm is made up of two parts: the first part decomposes the network into several independent areas based on community structure and decouples the information flow and control power among areas; the second part selects the center nodes from each area with the help of the control centrality index. As long as the status of center nodes is kept on a satisfactory level in each area, the whole system is under effective control. Finally, the algorithm is applied to power grids, and the simulations prove its effectiveness.Xiangping NI Shengwei MEI 2008控制理论与应用(英文版)2008,6,1:3

20High-risk phenotypes of genetic disease in a Neonatal Intensive Care Unit population显示文摘To the Editor: Genetic diseases contribute to 35% of deaths during the first year of life and are a significant cause of intensive care.[1] A previous study based on the China Neonatal Genomes Project investigated the genetic causes of early infant deaths and found that >25% of deceased neonates with genetic diagnoses can be cured if diagnosed in time.[2] Therefore, it is crucial to target and diagnose neonates with genetic diseases as early as possible. According to our experience, the typical phenotypes, such as special facial features or multiple congenital anomalies (MCAs), indicate a high risk of genetic disease and lead physicians to perform genetic testing in neonates as early as possible. However, in practice, infants without typical phenotypes typically undergo a long and costly diagnostic process before genetic diagnoses are confirmed. Moreover, a recent survey by the American College of Medical Genetics and Genomics (ACMG) and other national professional organizations indicated that there are insufficient numbers of qualified geneticists to fulfil genetic service needs.[3] The ACMG published the general clinical features for genetic testing indications. For example, patients with phenotypes or family history data that strongly implicate a genetic cause may undergo genetic testing.[1] However, the study indicated that many genetic conditions arise de novo or are inherited with no family history.[1] A previous study attempted to apply the non-phenotype-driven panel approach in neonates admitted to the neonate intensive care unit (NICU).[4] However, at present, the diagnostic yield is only 3.45% (1/29).[4] In addition, the economic and ethical issues associated with genomic screening remain challenging. Therefore, the available indications for genetic testing may improve the management of genetic diseases.Tiantian Xiao Qi Ni Huiyao Chen Huijun Wang Lin Yang Bingbing Wu Yun Cao Guoqiang Cheng Laishuan Wang Liyuan Hu Hongfang Mei Yulan Lu Mengchun Gong Xinran Dong Wenhao Zhou 2022Chinese Medical Journal2022,,5:2
