1Efficacy and safety of Yinchenwuling powder for hyperlipidemia: a systematic review and Meta-analysis显示文摘OBJECTIVE:To assess the clinical effectiveness and adverse effects of Yinchenwuling powder(YCWLP)in the treatment of hyperlipidemia using Meta-analysis.METHODS:Seven electronic databases were searched for randomized controlled trials designed to evaluate the clinical effectiveness of YCWLP for hyperlipidemia published in any language prior to February 2015.Two reviewers independently identified articles,extracted data,assessed quality,and cross-checked the results.Revman 5.3 was used to analyze the data.RESULTS:Only five randomized controlled trials with poor methodology were included in the analy-sis.The five trials compared YCWLP with conventional lipid-lowering drugs.Meta-analysis indicated that YCWLP was more effective at the levels of total cholesterol and triglycerides,while increasing the level of high-density lipoprotein cholesterol without serious adverse effects.However,it was not more effective than lipid-lowering drugs in reducing low-density lipoprotein cholesterol and improving hemorheology.CONCLUSION:YCWLP appeared to improve lipid levels.However,given the high risk of bias among the trials,we could not conclude that YCWLP was beneficial to patients with hyperlipidemia.More rigorous trials are required to provide stronger evidence for the conclusion.Yao Haiqiang Zhang Zengliang Wang Ji Zuo Jiacheng Chen Yu Zhu Libing Li Xiaoke Yang Zheng Wang Zisong Sun Ranran Xu Xuanxuan Li Changming Wu Yanling Li Lingru Wang Qi 2016Journal of Traditional Chinese Medicine2016,36,2:11
2Effect of non-solvent additives on the morphology,pore structure, and direct contact membrane distillation performance of PVDF-CTFE hydrophobic membranes显示文摘Four common types of additives for polymer membrane preparation including organic macromolecule and micromolecule additives, inorganic salts and acids, and the strong non-solvent H2 O were used to prepare poly(vinylidene fluoride-co-chlorotrifluoroethylene)(PVDF-CTFE) hydrophobic flat-sheet membranes. Membrane properties including morphology, porosity, hydrophobicity, pore size and pore distribution were investigated, and the permeability was evaluated via direct contact membrane distillation(DCMD) of 3.5 g/L Na Cl solution in a DCMD configuration. Both inorganic and organic micromolecule additives were found to slightly influence membrane hydrophobicity. Polyethylene glycol(PEG),organic acids, Li Cl, Mg Cl2, and Li Cl/H2 O mixtures were proved to be effective additives to PVDF-CTFE membranes due to their pore-controlling effects and the capacity to improve the properties and performance of the resultant membranes. The occurrence of a pre-gelation process showed that when organic and inorganic micromolecules were added to PVDF-CTFE solution, the resultant membranes presented a high interconnectivity structure. The membrane prepared with dibutyl phthalate(DBP) showed a nonporous surface and symmetrical cross-section. When H2 O and Li Cl/H2 O mixtures were also used as additives, they were beneficial for solid–liquid demixing, especially when Li Cl/H2 O mixed additives were used. The membrane prepared with 5% Li Cl + 2% H2 O achieved a flux of24.53 kg/(m2·hr) with 99.98% salt rejection. This study is expected to offer a reference not only for PVDF-CTFE membrane preparation but also for other polymer membranes.Libing Zheng Zhenjun Wu Yong Zhang Yuansong Wei Jun Wang 2016Journal of Environmental Sciences2016,28,7:5
3Inhibition of the PIN1-NRF2/GPX4 axis imparts sensitivity to cisplatin in cervical cancer cells显示文摘The incidence of cervical cancer(cC)ranks the fourth in female malignant tumors globally.Chemoresistance is one of the main causes of treatment failure in advanced recurrent CC.Prolyl isomerase 1(PIN1)is overexpressed in a variety of tumors,and is closely associated with the malignant potential of tumor cells,such as transformation,proliferation,invasion and metastasis.In the present study,we demonstrate that cell death induced by suppression of PIN1 could be inhibited by ferrostatin-1(Fer-1)and ferroptosis biomarkers including lactate dehydrogenase(LDH)release,lipid peroxidation and malondialdehyde(MDA)are upregulated by downregulating PIN1.We then discover that abrogation of PIN1 greatly decreases the level of glutathione peroxidase 4(GPX4)and the level of PIN1 is positively correlated with the level of GPX4.Furthermore,the knockdown of PIN1 promotes ferroptosis induced by RSL3.The mechanism involves PIN1 silencing which downregulates GPX4 by decreasing the level of nuclear factor E2-related factor 2(NRF2).Furthermore,overexpression of NRF2 inhibits RSL3-mediated ferroptosis of CC cells when PIN1 is silenced.In addition,our results indicate that cisplatin(DDP)induces ferroptosis,which is restrained by overexpression of PIN1.The PIN1 inhibitor,KPT-6566,promotes the cytotoxic effect of DDP.The present study reveals that PIN1 affects ferroptosis and sensitivity to DDP in CC cells via the NRF2/GPX4 axis,thereby identifying PIN1 as a potential therapeutic target for Cc.Zheng Zhang Qiangsheng Hu Shuang Ye Libing Xiang 2022Acta Biochimica et Biophysica Sinica2022,54,9:4
4Optimized pre-treatment of high strength food waste digestate by high content aluminum-nanocluster based magnetic coagulation显示文摘Coagulation-based pre-treatment efficiency of high strength digestate of food waste(HSDFW) anaerobic digestion is negated by organic ligand-catalyzed decomposition of coagulants. In this study, an efficient HSDFW pre-treatment method, magnetic seeds(MS) coagulation, was employed by using highly stable Keggin Al_(30) nanocluster(PAC_(30)), MS and polyacrylamide(PAM), and its operation was optimized by evaluating the performance of removing turbidity, total suspended solids(TSS), chemical oxygen demand(COD), and total phosphorous(TP) phosphate. Results showed that at the optimum dosage of 4.82 g/L, PAC_(30) demonstrated excellent removals as high as 98.93% ± 0.1% of turbidity, 98.04% ± 0.1% of TSS, 58.28% ± 0.3% of total COD, 99.98% ± 0.01% of TP and 99.50% ± 0.01% of dissolved phosphate, respectively. Apparent molecular weight(AMW) and three-dimensional excitation-emission matrix(3 D-EEM) fluorescence spectroscopy analyses demonstrated more efficient removal of dissolved organic matter(DOM), particularly non-biodegradable and hydrophobic components by PAC_(30) than commercial coagulant. The sedimentation was much improved from 40 min by coagulation/flocculation to about 5 min settling by MS coagulation. The PAC_(30) based magnetic coagulation(MC) presents theoretical guidance on a cost-effective and much less footprint pre-treatment alternative for high strength wastewater.Tharindu Ritigala Hailu Demissie Yanlin Chen Jiaxi Zheng Libing Zheng Jinxing Zhu Hua Fan Jiao Li Dongsheng Wang Sujithra KWeragoda Rohan Weerasooriya Yuansong Wei 2021Journal of Environmental Sciences2021,33,6:4
5Antibacterial and antiparasitic activities analysis of a hepcidinlike antimicrobial peptide from Larimichthys crocea显示文摘As an economically important marine fish,the large yellow croaker Larimichthys crocea suffered from marine white spot disease caused by the ectoparasite Cryptocaryon irritans in recent years.This disease not only could result in physiological damage,but also lead to secondary bacterial invasion.Reports indicated some AMPs(antimicrobial peptides)were of antiparasitic activity to C.irritans.Hepcidin-like(Lc-HepL)was one of the significant differential expression genes excavated from the transcriptome following a challenge with C.irritans.In this study,we characterized this AMP’s bioactivity based on the levels of mRNA and protein.After challenged by C.irritans,qRT-PCR showed Lc-HepL was significantly upregulated in six tissues,including gill,muscle,liver,head kidney and spleen during theront infection,trophont falling off,and secondary bacterial invasion stages,which implicated a role Lc-HepL played in the immune defense against C.irritans and secondary bacterial infection.Recombinant Lc-HepL(rLc-HepL)was induced and purified successfully.rLc-HepL exhibited antibacterial activity to certain bacteria in a dose-and time-dependent manners.Anti-C.irritans activity was explored for the first time and found it could cause the theronts membrane rupture and contents leakage.These results provided the first evidence that Lc-HepL had strong antiparasitic activity against marine fish ectoparasites C.irritans theronts.Together,data indicated that Lc-HepL might be an important component in the innate immune system against C.irritans and has the potential to be employed in future drug development.Libing Zheng Yuan Li Jun Wang Ying Pan Jia Chen Weiqiang Zheng Longshan Lin 2020Acta Oceanologica Sinica2020,39,10:1
6Identification and Expression Profile of a Neuropeptide LFRFamide-Like Gene During Different Stages of Gonadal Development in the Cephalopod Sepia pharaonis显示文摘Neuropeptides are widely distributed in vertebrates and invertebrates,regulating a variety of physiological activities in the organisms,such as metabolism,feeding and reproduction.In this study,to explore the function of neuropeptide LFRFamide in Sepia pharaonis,the full-length cDNA of LFRFamide-like gene(named SpLFRFL,MG869822.1)was identified with rapid amplification of cDNA ends(RACE)method.The sequence of SpLFRFL was 860 bp in length and encoded 188 amino acids containing 4 different mature peptides:1 copy of PHTPFRFamide,NSLFRFamide,TIFRFamide,and 3 copies of GNLFRFamide.Multiple alignment and phylogenetic analysis results showed that SpLFRFL shared high identity with LFRFamides of Sepia officinalis and Sepiella japonica and had the closest relationship with them.Through quantitative Real-time PCR(qRT-PCR),it was found that the SpLFRFL gene was highly expressed in the optic lobe and brain at three different stages during gonad development in both genders.Moreover,the four mature peptides at a concentration of 0.01μmol L^(−1) could inhibit the protein synthesis in the Chinese hamster ovary cell strain-K1(CHOK1)induced by SpGnRH.These data suggest that SpLFRFL might be involved in the development and reproduction of S.pharaonis.The results can contribute to future studies on neuropeptide evolution and function and benefit the cuttlefish farming.QIU Jiayin SUN Lianlian LI Shuang ZHOU Xu CHI Changfeng ZHENG Libing 2024Journal of Ocean University of China2024,23,2:0
7Omadacycline for the treatment of Legionella pneumophila pneumonia caused by drowning:a case report显示文摘Drowning is a major cause of preventable death and pathology worldwide.Every year,more than 295,000people die from accidental drowning.Ninety percent of accidental drowning deaths occur in low-and middleincome countries,and nearly half occur in people under the age of 25.Xiao Lu Wenqi Qi Haizhen Wang Zhongjun Zheng Libing Jiang Shanxiang Xu 2023World Journal of Emergency Medicine2023,14,6:0
8City-Specific Effects of Lifting Mobility Restrictions—China, February–March 2020显示文摘Summary What is already known about this topic?Government used mobility restrictions to help contain the first wave of coronavirus disease 2019(COVID-19)across cities in China.The restrictions were lifted during times of non-zero incidence in response to a return to work order that went into effect on February 10,2020.What is added by this report?The effect of lifting mobility restrictions on COVID-19 death rate and incidence varied by city,with smaller increases or even reductions in cities with low community connectivity and small floating volume,and larger increases in cities with high community connectivity and large floating volume.Effects on recovery rates were similar across cities.What are the implications for public health practice?City-specific mobility restriction lifting is likely to be beneficial.Two indexes,community connectivity and floating volume,can inform the design of city-specific mobility restriction lifting policies.Shasha Han Libing Ma Ting Zhang Luzhao Feng Weizhong Yang Xiaoying Zheng 2022China CDC weekly2022,4,31:0
9Inhibition of MALT1 paracaspase activity improves lesion recovery following spinal cord injury显示文摘Spinal cord injury(SCI) is a devastating traumatic injury that causes persistent, severe motor and sensory dysfunction. Immune responses are involved in functional recovery after SCI. Mucosa-associated lymphoid tissue lymphoma translocation 1(MALT1) has been shown to regulate the survival and differentiation of immune cells and to play a critical role in many diseases, but its function in lesion recovery after SCI remains unclear. In this paper, we generated KI(knock in) mice with a point mutation(C472 G) in the active center of MALT1 and found that the KI mice exhibited improved functional recovery after SCI.Fewer macrophages were recruited to the injury site in KI mice and these macrophages differentiated into anti-inflammatory macrophages. Moreover, macrophages from KI mice exhibited reduced phosphorylation of p65, which in turn resulted in decreased SOCS3 expression and increased pSTAT6 levels.Similar results were obtained upon inhibition of MALT1 paracaspase with the small molecule inhibitor‘‘MI-2' or the more specific inhibitor ‘‘MLT-827'. In patients with SCI, peripheral blood mononuclear cells(PBMC) displayed increased MALT1 paracaspase. Human macrophages showed reduced proinflammatory and increased anti-inflammatory characteristics following the inhibition of MALT1 paracaspase. These findings suggest that inhibition of MALT1 paracaspase activity in the clinic may improve lesion recovery in subjects with SCI.Hua Zhang Guodong Sun Xiaowei Li Zhen Fu Chengbin Guo Guangchao Cao Baocheng Wang Qian Wang Shuxian Yang Dehai Li Xichun Xia Peng Li Jing Zhu Wei Zhou Liangyan Zheng Jingxia Li Lei Zhang Jianlei Hao Libing Zhou Frederic Bornancin Zhizhong Li Zhinan Yin Yunfei Gao 2019Science Bulletin2019,64,16:0

11Accelerating hybrid and compact neural networks targeting perception and control domains with coarse-grained dataflow reconfiguration显示文摘Driven by continuous scaling of nanoscale semiconductor technologies,the past years have witnessed the progressive advancement of machine learning techniques and applications.Recently,dedicated machine learning accelerators,especially for neural networks,have attracted the research interests of computer architects and VLSI designers.State-of-the-art accelerators increase performance by deploying a huge amount of processing elements,however still face the issue of degraded resource utilization across hybrid and non-standard algorithmic kernels.In this work,we exploit the properties of important neural network kernels for both perception and control to propose a reconfigurable dataflow processor,which adjusts the patterns of data flowing,functionalities of processing elements and on-chip storages according to network kernels.In contrast to stateof-the-art fine-grained data flowing techniques,the proposed coarse-grained dataflow reconfiguration approach enables extensive sharing of computing and storage resources.Three hybrid networks for MobileNet,deep reinforcement learning and sequence classification are constructed and analyzed with customized instruction sets and toolchain.A test chip has been designed and fabricated under UMC 65 nm CMOS technology,with the measured power consumption of 7.51 mW under 100 MHz frequency on a die size of 1.8×1.8 mm^2.Zheng Wang Libing Zhou Wenting Xie Weiguang Chen Jinyuan Su Wenxuan Chen Anhua Du Shanliao Li Minglan Liang Yuejin Lin Wei Zhao Yanze Wu Tianfu Sun Wenqi Fang Zhibin Yu 2020Journal of Semiconductors2020,41,2:0
12Potential anticancer activity analysis of piscidin 5-like from Larimichthys crocea显示文摘Antitumor activity is one characteristic function of some certain antimicrobial peptides(AMPs)found in recent years.In the present study,we attempted to detect potential anticancer activity of a recombinant piscidin 5-like from Larimichthys crocea(r Lc-P5L)which owned widely antibacterial and strong antiparasitic activity in vitro.The light microscope observation indicated r Lc-P5L was of antitumor activity to He La cells,293 T cells and L929 cells.MTT assay showed the toxic sensitivity of r Lc-P5L to three tumor cell strains was 293 T>L929>He La.Scanning electron microscope(SEM)results showed r Lc-P5L behaved like a lytic peptide to cause damage on cells membrane of L929 cells by forming globular clusters,even pores at 60μmol/L,or degrading membrane to make it completely lose cytoskeleton structure at 80μmol/L;r Lc-P5L treatment also resulted in DNA degradation.Fluorescence observation results indicated r Lc-P5L could cause L929 cells at least two obvious changes:one is nucleus,nuclear chromatin condensed in the margin,nuclear volume became smaller and shrank to be out of shape,or lysed to be debris;the other is cytoskeleton,they became disordered and polarized to make cells atrophic shapes,or even lysed to be debris.In summary,r Lc-P5L owned potential anticancer activity causing membrane structure damage and genome DNA degradation.Interestingly,treatment with different concentration of r Lc-P5L seemingly caused the similar but different changes,whether it indeed gave rise to cancer cells diverse death way,the further studies should be performed,and the detailed mechanisms were still need further explored.Libing Zheng Jiayin Qiu Huihui Liu Changfeng Chi Longshan Lin 2022Acta Oceanologica Sinica2022,41,3:0
13Expert Consensus on Nutritional Support for Children with Congenital Heart Disease(2023 Edition)显示文摘The second edition of the expert consensus on pediatric nutrition was formed based on a global update of pedia-tric nutrition guidelines or consensus worldwide,the management of congenital heart disease,and the results of multi-center clinical nutrition research for congenital heart disease following thefirst Chinese consensus edition of 2016.The consensus was also shaped by the results of three discussion sessions and two questionnaires con-ducted by the 13-member collaboration group.This process was informed by both clinical guidelines and expert consensus.The quality of literature,both in English and Chinese,and the level of recommendations were evaluated using the Grading of Recommendations Assessment,Development,and Evaluations(GRADE)system.Xuming Mo Wei Cai Jirong Qi Zhuoming Xu Ying Wang Weihui Yan Shoujun Li Nianguo Dong Xinxin Chen Jinfen Liu Qiang Shu Jimei Chen Haibo Zhang Hao Zhang Quansheng Xing Qi An Xiaofeng Li Xu Wang Yan He Junwu Su Taibing Fan Teng Ming Weibing Tang Li Hong Jinghao Zheng Ming Ye Guocheng Sun Yiqun Ding Liang Tao Yifeng Yang Zhongshi Wu Hua Cao Qiang Wang Keming Yang Libing Zhang Ping Wen Yanqin Cui Bo Zhai Yong Zou Qingya Tang Rui Chen Chun Wu Zhiyu Feng Caixia Liu Yaping Mi Rufang Zhang Ke Lin Xin Li Mingan Pi Xiangming Fan Shanshan Shi Peng Huang Zhengxia Pan Jiafeng Qi Renwei Chen Shuguang Tao Yaqin Shu Huifeng Zhang Lan Jiang Min Da Nishant Patel Liang Hu Cardiac Surgery Group of Pediatric Surgery Society of Chinese Medical Association and Parenteral Enteral Nutrition Society of Chinese Medical Association 2023Congenital Heart Disease2023,18,6:0
14A modified OMP method for multi-orbit three dimensional ISAR imaging of the space target显示文摘The conventional two dimensional(2D)inverse synthetic aperture radar(ISAR)imaging fails to provide the targets'three dimensional(3D)information.In this paper,a 3D ISAR imaging method for the space target is proposed based on mutliorbit observation data and an improved orthogonal matching pursuit(OMP)algorithm.Firstly,the 3D scattered field data is converted into a set of 2D matrix by stacking slices of the 3D data along the elevation direction dimension.Then,an improved OMP algorithm is applied to recover the space target's amplitude information via the 2D matrix data.Finally,scattering centers can be reconstructed with specific three dimensional locations.Numerical simulations are provided to demonstrate the effectiveness and superiority of the proposed 3D imaging method.JIANG Libing ZHENG Shuyu YANG Qingwei YANG Peng WANG Zhuang 2023Journal of Systems Engineering and Electronics2023,34,4:0
