2Molecular screening of patients with nonsyndromic hearing loss from Nanjing city of China显示文摘Hearing loss is the most frequent sensory disorder involving a multitude of factors,and at least 50% of cases are due to genetic etiology.To further characterize the molecular etiology of hearing loss in the Chinese population,we recruited a total of 135 unrelated patients with nonsyndromic sensorineural hearing loss (NSHL) for mutational screening of GJB2,GJB3,GJB6,SLC26A4,SLC26A5 IVS2-2A>G and mitochondrial 12SrRNA,tRNA Ser(UCN) by PCR amplification and direct DNA sequencing.The carrier frequencies of deafness-causing mutations in these patients were 35.55% in GJB2,3.70% in GJB6,15.56% in SLC26A4 and 8.14% in mitochondrial 12SrRNA,respectively.The results indicate the necessity of genetic screening for mutations of these causative genes in Chinese population with nonsyndromic hearing loss.Yajie Lu Dachun Dai Zhibin Chen Xin Cao Xingkuan Bu Qinjun Wei Guangqian Xing 2011The Journal of Biomedical Research2011,25,5:30
3High-entropy ceramics:Present status,challenges,and a look forward显示文摘High-entropy ceramics (HECs) are solid solutions of inorganic compounds with one or more Wyckoff sites shared by equal or near-equal atomic ratios of multi-principal elements.Although in the infant stage,the emerging of this new family of materials has brought new opportunities for material design and property tailoring.Distinct from metals,the diversity in crystal structure and electronic structure of ceramics provides huge space for properties tuning through band structure engineering and phonon engineering.Aside from strengthening,hardening,and low thermal conductivity that have already been found in high-entropy alloys,new properties like colossal dielectric constant,super ionic conductivity,severe anisotropic thermal expansion coefficient,strong electromagnetic wave absorption,etc.,have been discovered in HECs.As a response to the rapid development in this nascent field,this article gives a comprehensive review on the structure features,theoretical methods for stability and property prediction,processing routes,novel properties,and prospective applications of HECs.The challenges on processing,characterization,and property predictions are also emphasized.Finally,future directions for new material exploration,novel processing,fundamental understanding,in-depth characterization,and database assessments are given.Huimin XIANG Yan XING Fu-zhi DAI Hongjie WANG Lei SU Lei MIAO Guojun ZHANG Yiguang WANG Xiwei QI Lei YAO Hailong WANG Biao ZHAO Jianqiang LI Yanchun ZHOU 2021Journal of Advanced Ceramics2021,10,3:28

6Effects of slow or controlled release fertilizer types and fertilization modes on yield and quality of rice显示文摘There is limited information about the influence of slow or controlled release fertilizer(S/CRF) on rice yield and quality. In this study, japonica rice cultivar Nanjing 9108 was used to study the effects of three different S/CRFs(polymer-coated urea(PCU), sulfur-coated urea(SCU), and urea formaldehyde(UF)) and two fertilization modes(both S/CRF and common urea(CU) as basal fertilizer, S/CRF as basal and CU as tillering fertilizer) on rice yield and quality. CU only was applied separately as control(CK). Results showed that, rice grain yield, chalky kernel rate, chalky area, overall chalkiness, and the content of gliadin, glutenin, and protein, all showed the trends of UF>PCU>SCU within the same fertilization mode, and showed the trends of S/CRF as basal and CU as tillering fertilizer>both S/CRF and CU as basal fertilizer within the same type of S/CRF. In contrast, the contents of amylose, amylopectin, and starch, as well as taste value, and peak and hot viscosity showed trends of SCU>PCU>UF, and the trends of both S/CRF and CU as basal fertilizer>S/CRF as basal and CU as tillering fertilizer. Among S/CRF treatments and fertilization modes, taste values of cooked rice were positively correlated with amylose, amylopectin, and starch contents, as well as gel consistency, peak viscosity, hot viscosity, and cool viscosity, while negatively correlated with globulin, gliadin, glutenin, and protein contents. The types of S/CRF and fertilization modes are important for improving rice yield and quality. Compared to CK, higher yield and similar quality of rice was achieved with UF as basal and CU as tillering fertilizer, and similar yield with improved appearance and eating and cooking quality of rice was achieved with either both UF and CU as basal fertilizer, or PCU as basal and CU as tillering fertilizer.WEI Hai-yan CHEN Zhi-feng XING Zhi-peng ZHOU Lei LIU Qiu-yuan ZHANG Zhen-zhen JIANG Yan HU Ya-jie ZHU Jin-yan CUI Pei-yuan DAI Qi-gen ZHANG Hong-cheng 2018Journal of Integrative Agriculture2018,17,10:19
7One-year clinical study of NeuroR egen scaffold implantation following scar resection in complete chronic spinal cord injury patients显示文摘The objective of this clinical study was to assess the safety and feasibility of the collagen scaffold, Neuro Regen scaffold, one year after scar tissue resection and implantation. Scar tissue is a physical and chemical barrier that prevents neural regeneration. However, identification of scar tissue is still a major challenge. In this study, the nerve electrophysiology method was used to distinguish scar tissue from normal neural tissue, and then different lengths of scars ranging from 0.5–4.5 cm were surgically resected in five complete chronic spinal cord injury(SCI) patients. The NeuroR egen scaffold along with autologous bone marrow mononuclear cells(BMMCs), which have been proven to promote neural regeneration and SCI recovery in animal models, were transplanted into the gap in the spinal cord following scar tissue resection. No obvious adverse effects related to scar resection or Neuro Regen scaffold transplantation were observed immediately after surgery or at the 12-month follow-up. In addition, patients showed partially autonomic nervous function improvement, and the recovery of somatosensory evoked potentials(SSEP) from the lower limbs was also detected. The results indicate that scar resection and Neuro Regen scaffold transplantation could be a promising clinical approach to treating SCI.Zhifeng Xiao Fengwu Tang Jiaguang Tang Huilin Yang Yannan Zhao Bing Chen Sufang Han Nuo Wang Xing Li Shixiang Cheng Guang Han Changyu Zhao Xiaoxiong Yang Yumei Chen Qin Shi Shuxun Hou Sai Zhang Jianwu Dai 2016Science China(Life Sciences)2016,59,7:18

9Human placenta-derived mesenchymal stem cells loaded on linear ordered collagen scaffold improves functional recovery after completely transected spinal cord injury in canine显示文摘Traumatic spinal cord injury(SCI) is a major challenge in the clinic. In this study, we sought to examine the synergistic effects of linear ordered collagen scaffold(LOCS) and human placenta-derived mesenchymal stem cells(hPMSCs) when transplanted into completely transected beagle dogs. After 36 weeks observation, we found that LOCS+hPMSCs implants promoted better hindlimb locomotor recovery than was observed in the non-treatment(control) group and LOCS group. Histological analysis showed that the regenerated tissue after treatment was well integrated with the host tissue, and dramatically reduced the volume of cystic and chondroitin sulfate proteoglycans(CSPGs) expression. Furthermore, the LOCS+hPMSCs group also showed more neuron-specific βIII-tubulin(Tuj-1)-and NeuN-positive neurons in the lesion area, as well as axonal regeneration, remyelination and synapse formation in the lesion site. Additionally, dogs in the LOCS+hPMSCs group experienced enhanced sprouting of both ascending(CGRP-positive) sensory fibers and descending(5-HT-and TH-positive) motor fibers at the lesion area. All these data together suggested that the combined treatment had beneficial effects on neuronal regeneration and functional improvement in a canine complete transection model. Therefore, LOCS+hPMSCs implantation holds a great promise for bridging the nerve defect and may be clinically useful in the near future.Sufang Han Zhifeng Xiao Xing Li Huan Zhao Bin Wang Zhixue Qiu Zhi Li Xin Mei Bai Xu Caixia Fan Bing Chen Jin Han Yanzheng Gu Huilin Yang Qin Shi Jianwu Dai 2018Science China(Life Sciences)2018,61,1:15
10Effects of Salvia miltiorrhiza on intestinal microflora in rats with ischemia/reperfusion liver injury显示文摘BACKGROUND: Hepatic ischemia/reperfusion injury may induce intestinal microflora imbalance. Salvia miltiorrhiza is effective in promoting blood circulation and counteracting peroxidation in tissues. The aim of the present study was to determine the effects of Salvia miltiorrhiza on intestinal mi- croflora, endotoxemia, and bacterial translocation in rats with hepatic I/R injury. METHODS: Sprague-Dawley rats in specific pathogen free grade were divided into 3 groups: group I(n =6) for sham operation: groups ( n = 7) for liver ische- mia for 20 minutes and reperfusion for 22 hours. Group was also pretreated with 4 ml/day of Salvia miltiorrhiza solu- tion (250 mg/kg) by daily gavage for 7 days. The levels of serum alanine aminotransferase (ALT), aspartate amino- transferase (AST), malondialdehyde ( MDA) and supero- xide dismutase ( SOD ) in liver tissues, serum endotoxin, intestinal bacterial counts, intestinal mucosal histology and bacterial translocation were studied. RESULTS: The levels of ALT, AST, plasma endotoxin and MDA in liver tissues were decreased more markedly in group (57.57 ± 18.08 U/L, 147.57 ±40.84 U/L, 0.42 ± 0.144 EU/ml and 0. 52 ±0.19 nmol/mg-prot respectively) in group 295.9±216.92 U/L, 0.80± 0.262 EU/ml and 0.72±0.12 nmol/mg-prot; P <0.05-0.01 respectively). Liver SOD activity was increased more sig- nificantly in group (318.47±64.62 U/mg-prot) than in group U/mg-prot, P<0.05). The counts of Bifidobacteria and Bacteroides increased more significantly in group than in group but were similar to those in group I. Bacterial translocation to the kidney in group was 50% (5/10), whereas no bacterial translocation to the kidney occurred in the other two groups (P <0. 01). Ileal mucosal structure was markedly ameliorated in group as compared with group CONCLUSIONS: Salviae miltiorrhiza could partially restore intestinal microflora balance, improve intestinal mucosal integrity, and reduce bacterial translocation and plasma en- dotoxin in rats with hepatic ischemia/reperfusion injury.Hui-Chun Xing, Lan-Juan Li, Kai-Jin Xu, Tian Shen, Yun-Bo Chen, Yu Chen, Su-Zhen Fu, Ji-Fang Sheng, Chun-Lei Chen, Jian-Guo Wang, Dong Yan, Fang-Wei Dai and Xiao-Ying Sha Hangzhou, China Key Laboratory of Infectious Diseases, Ministry of Public Health of China, and Institute of Infectious Diseases, Department of Infectious Diseases, First Affiliated Hospital, Zhejiang University School of Medicine, Hangzhou 310003, China Zhejiang Academy of Medical Sciences, Hangzhou 310012, China 2005Hepatobiliary & Pancreatic Diseases International2005,4,2:14
11Combined effect of shading time and nitrogen level on grain filling and grain quality in japonica super rice显示文摘There is limited information about the combined effect of shading time and nitrogen(N) on grain filling and quality of rice. Therefore, two japonica super rice cultivars, Nanjing 44 and Ningjing 3, were used to study the effect of shading time and N level on the characteristics of rice panicle and grain filling as well as the corresponding yield and quality. At a low N level(150 kg N ha^(–1), 150 N), grain yield decreased(by 21.07–26.07%) under the treatment of 20 days of shading before heading(BH) compared with the no shading(NS) treatment. These decreases occurred because of shortened panicle length, decreased number of primary and secondary branches, as well as the grain number and weight per panicle. At 150 N, in the treatment of 20 days of shading after heading(AH), grain yield also decreased(by 9.46–10.60%) due to the lower grain weight per panicle. The interaction of shading and N level had a significant effect on the number of primary and secondary branches. A high level of N(300 kg N ha^(–1), 300 N) could offset the negative effect of shading on the number of secondary branches and grain weight per panicle, and consequently increased the grain yield in both shading treatments. In superior grains, compared with 150 N NS, the time to reach 99% of the grain weight(T_(99)) was shortened by 1.6 to 1.7 days, and the grain weight was decreased by 4.18–5.91% in 150 N BH. In 150 N AH, the grain weight was 13.39–13.92% lower than that in 150 N NS due to the slow mean and the maximum grain-filling rate(GR_(mean )and GR_(max)). In inferior grains, grain weight and GR_(mean) had a tendency of 150 N NS>150 N BH>150 N AH. Under shaded conditions, 300 N decreased the grain weight due to lower GR_(mean) both in superior and inferior grains. Compared with 150 N NS, the milling and appearance qualities as well as eating and cooking quality were all decreased in 150 N BH and 150 N AH. Shading with the high level of 300 N improved the milling quality and decreased the number of chalky rice kernels, but the eating and cooking quality was reduced with increased chalky area and overall chalkiness. Therefore, in the case of short term shading, appropriate N fertilizer could be used to improve the yield and milling quality of rice, but limited application of N fertilizer is recommended to achieve good eating and cooking quality of rice.WEI Hai-yan ZHU Ying QIU Shi HAN Chao HU Lei XU Dong ZHOU Nian-bing XING Zhi-peng HU Ya-jie CUI Pei-yuan DAI Qi-gen ZHANG Hong-cheng 2018Journal of Integrative Agriculture2018,17,11:13
12Suitable growing zone and yield potential for late-maturity type of Yongyou japonica/indica hybrid rice in the lower reaches of Yangtze River, China显示文摘Late-maturity type of Yongyou japonica/indica hybrids series(LMYS) have shown great yield potential, and are being widely planted in the lower reaches of Yangtze River, China. Knowledge about suitable growing zone and evaluation of yield advantage is of practical importance for LMYS in this region. Fifteen LMYS, two high-yielding inbred japonica check varieties(CK-J) and two high-yielding hybrid indica check varieties(CK-I) were grown at Xinghua(119.57°E, 33.05°N) of Lixiahe region, Yangzhou(119.25°E, 32.30°N) of Yanjiang region, Changshu(120.46°E, 31.41°N) of Taihu Lake region, and Ningbo(121.31°E, 29.45°N) of Ningshao Plain in 2013 and 2014. The results showed that maturity dates of the 15 were later than the secure maturity date at Xinghua and 6, 14 and 15 LMYS were mature before the secure maturity date at Yangzhou, Changshu and Ningbo, respectively. One variety was identified as high-yielding variety among LMYS(HYYS) at Yangzhou, 8 HYYS in 2013 and 9 HYYS in 2014 at Changshu, 9 HYYS at Ningbo. HYYS here referred to the variety among LMYS that was mature before the secure maturity date and had at least 8% higher grain yield than both CK-J and CK-I at each experimental site. Grain yield of HYYS at each experimental site was about 12.0 t ha–1 or higher, and was significantly higher than CK varieties. High yield of HYYS was mainly attributed to larger sink size due to more spikelets per panicle. Plant height of HYYS was about 140 cm, and was significantly higher than check varieties. Significant positive correlations were recorded between duration from heading to maturity stage and grain yield, and also between whole growth periods and grain yield. HYYS had obvious advantage over check varieties in biomass accumulation and leaf area duration from heading to maturity stage. Comprehensive consideration about safe maturity and yield performance of LMYS at each experimental site, Taihu Lake region(representative site Changshu) and Ningshao Plain(representative site Ningbo) were thought suitable growing zones for LMYS in the lower reaches of Yangtze River. The main factors underlying high yield ofHYYS were larger sink size, higher plant height, longer duration from heading to maturity stage and whole growth periods, and higher biomass accumulation and leaf area duration during grain filling stage.WEI Huan-he 2016Journal of Integrative Agriculture2016,15,1:13
13Management of granulomatous lobular mastitis: an international multidisciplinary consensus(2021 edition)显示文摘Granulomatous lobular mastitis(GLM) is a rare and chronic benign inflammatory disease of the breast. Difficulties exist in the management of GLM for many front-line surgeons and medical specialists who care for patients with inflammatory disorders of the breast. This consensus is summarized to establish evidence-based recommendations for the management of GLM. Literature was reviewed using PubMed from January 1, 1971 to July 31, 2020. Sixty-six international experienced multidisciplinary experts from 11 countries or regions were invited to review the evidence.Levels of evidence were determined using the American College of Physicians grading system, and recommendations were discussed until consensus. Experts discussed and concluded 30 recommendations on historical definitions,etiology and predisposing factors, diagnosis criteria, treatment, clinical stages, relapse and recurrence of GLM. GLM was recommended as a widely accepted definition. In addition, this consensus introduced a new clinical stages and management algorithm for GLM to provide individual treatment strategies. In conclusion, diagnosis of GLM depends on a combination of history, clinical manifestations, imaging examinations, laboratory examinations and pathology.The approach to treatment of GLM should be applied according to the different clinical stage of GLM. This evidencebased consensus would be valuable to assist front-line surgeons and medical specialists in the optimal management of GLM.Qian-Qian Yuan Shu-Yuan Xiao Omar Farouk Yu-Tang Du Fereshte Sheybani Qing Ting Tan Sami Akbulut Kenan Cetin Afsaneh Alikhassi Rami Jalal Yaghan Irmak Durur-Subasi Fatih Altintoprak Tae Ik Eom Fatih Alper Mustafa Hasbahceci David Martínez-Ramos Pelin Seher Oztekin Ava Kwong Cedric W.Pluguez-Turul Kirstyn EBrownson Shirish Chandanwale Mehran Habib Liu-Yi Lan Rui Zhou Xian-Tao Zeng Jiao Bai Jun-Wen Bai Qiong-Rong Chen Xing Chen Xiao-Ming Zha Wen-Jie Dai Zhi-Jun Dai Qin-Yu Feng Qing-Jun Gao Run-Fang Gao Bao-San Han Jin-Xuan Hou Wei Hou Hai-Ying Liao Hong Luo Zheng-Ren Liu Jing-Hua Lu Bin Luo Xiao-Peng Ma Jun Qian Jian-Yong Qin Wei Wei Gang Wei Li-Ying Xu Hui-Chao Xue Hua-Wei Yang Wei-Ge Yang Chao-Jie Zhang Fan Zhang Guan-Xin Zhang Shao-Kun Zhang Shu-Qun Zhang Ye-Qiang Zhang Yue-Peng Zhang Sheng-Chu Zhang Dai-Wei Zhao Xiang-Min Zheng Le-Wei Zheng Gao-Ran Xu Wen-Bo Zhou Gao-Song Wu 2022Military Medical Research2022,9,4:13
14Enhanced therapeutic effects of combined chemotherapeutic drugs and midkine antisense oligonucleotides for hepatocellular carcinoma显示文摘AIM: To evaluate the effect of combined antisense oligonucleotides targeting midkine (MK-AS) and chemotherapeutic drugs [cisplatin(DDP), 5-fluorouracil (5-FU) and adriamycin (ADM)] on inhibition of HepG2 cell proliferation, and to analyze the efficacy of MK-AS used in combined ADM in in situ human hepatocellular carcinoma (HCC) model. METHODS: HepG2 cells were treated with MK-AS and/or chemotherapeutic drugs mediated by Lipofectin, and cell growth activity was determined by MTS assay. An in situ HCC model was used in this experiment. MK- AS, ADM and MK-AS + ADM were given intravenously for 20 d, respectively. The animal body weight and their tumor weight were measured to assess the effect of the combined therapy in vivo. RESULTS: Combined treatment with MK-AS reduced the IC50 of DDP, 5-FU and ADM in HepG2 cells. MK-AS significantly increased the inhibition rate of DDP, 5-FU and ADM. Additionally, synergism (Q 1.15) occurred at a lower concentration of ADM, 5-FU and DDP with combined MK-AS. Combined treatment with MK-AS and ADM resulted in the more growth inhibition on in situ human HCC model compared with treatment with chemotherapeutic drugs alone. CONCLUSION: MK-AS increases the chemosensitivity in HepG2 cells and in situ human HCC model, and thecombination of MK-AS and ADM has a much better in vitro and in vivo synergism.Li-Cheng Dai Xiang Wang Xing Yao Yong-Liang Lu Jin-Liang Ping Jian-Fang He 2007World Journal of Gastroenterology2007,13,13:10
15Efficacy and safety of the long-acting fusion inhibitor albuvirtide in antiretroviral-experienced adults with human immunodeficiency virus-1:interim analysis of the randomized,controlled,phase 3,non-inferiority TALENT study显示文摘Background:Albuvirtide is a once-weekly injectable human immunodeficiency virus(HIV)-1 fusion inhibitor.We present interim data for a phase 3 trial assessing the safety and efficacy of albuvirtide plus lopinavir-ritonavir in HIV-1-infected adults already treated with antiretroviral drugs.Methods:We carried out a 48-week,randomized,controlled,open-label non-inferiority trial at 12 sites in China.Adults on the World Health Organization(WHO)-recommended first-line treatment for>6 months with a plasma viral load>1000 copies/mL were enrolled and randomly assigned(1:1)to receive albuvirtide(once weekly)plus ritonavir-boosted lopinavir(ABT group)or the WHO-recommended second-line treatment(NRTI group).The primary endpoint was the proportion of patients with a plasma viral load below 50 copies/mL at 48 weeks.Non-inferiority was prespecified with a margin of 12%.Results:At the time of analysis,week 24 data were available for 83 and 92 patients,and week 48 data were available for 46 and 50 patients in the albuvirtide and NRTI groups,respectively.At 48 weeks,80.4%of patients in the ABT group and 66.0%of those in the NRTI group had HIV-1 RNA levels below 50 copies/mL,meeting the criteria for non-inferiority.For the per-protocol population,the superiority of albuvirtide over NRTI was demonstrated.The frequency of grade 3 to 4 adverse events was similar in the two groups;the most common adverse events were diarrhea,upper respiratory tract infections,and grade 3 to 4 increases in triglyceride concentration.Renal function was significantly more impaired at 12 weeks in the patients of the NRTI group who received tenofovir disoproxil fumarate than in those of the ABT group.Conclusions:The TALENT study is the first phase 3 trial of an injectable long-acting HIV drug.This interim analysis indicates that once-weekly albuvirtide in combination with ritonavir-boosted lopinavir is well tolerated and non-inferior to the WHO-recommended second-line regimen in patients with first-line treatment failure.Trial registration:ClinicalTrials.gov Identifier:NCT02369965;http://gffzz90ed6ce9d87f4798s6bkbn0ppfn0u6qop.ffgz.tsg.suse.edu.cn Clinical Trial Registry No.ChiCTR-TRC-14004276;http://gffzz62a03ee25e6f4a77h6bkbn0ppfn0u6qop.ffgz.tsg.suse.edu.cn/enindex.aspx.Bin Su Cheng Yao Qing-Xia Zhao Wei-Ping Cai Min Wang Hong-Zhou Lu Yuan-Yuan Chen Li Liu Hui Wang Yun He Yu-Huang Zheng Ling-Hua Li Jin-Feng Chen Jian-Hua Yu Biao Zhu Min Zhao Yong-Tao Sun Wen-Hui Lun Wei Xia Li-Jun Sun Li-Li Dai Tai-Yi Jiang Mei-Xia Wang Qing-Shan Zheng Hai-Yan Peng Yao Wang Rong-Jian Lu Jian-Hua Hu Hui Xing Yi-Ming Shao Dong Xie Tong Zhang Fu-Jie Zhang Hao Wu TALENT Study Team 2020Chinese Medical Journal2020,,24:10
16Data processing and initial results of Chang'e-3 lunar penetrating radar显示文摘To improve our understanding of the formation and evolution of the Moon,one of the payloads onboard the Chang'e-3(CE-3) rover is Lunar Penetrating Radar(LPR). This investigation is the first attempt to explore the lunar subsurface structure by using ground penetrating radar with high resolution. We have probed the subsurface to a depth of several hundred meters using LPR. In-orbit testing, data processing and the preliminary results are presented. These observations have revealed the configuration of regolith where the thickness of regolith varies from about 4 m to 6 m.In addition, one layer of lunar rock, which is about 330 m deep and might have been accumulated during the depositional hiatus of mare basalts, was detected.Yan Su Guang-You Fang Jian-Qing Feng Shu-Guo Xing Yi-Cai Ji Bin Zhou Yun-Ze Gao Han Li Shun Dai Yuan Xiao Chun-Lai Li 2014Research in Astronomy and Astrophysics2014,14,12:10
17CP-25 reverses prostaglandin E4 receptor desensitization-induced fibroblast-like synoviocyte dysfunction via the G protein-coupled receptor kinase 2 in autoimmune arthritis显示文摘Paeoniflorin-6’-O-benzene sulfonate (CP-25) is a novel compound derived from paeoniflorin that has been demonstrated to have therapeutic effects in a rat model of rheumatoid arthritis (RA). However, the underlying mechanism has not been elucidated to date. We explored this mechanism in the present study by treating rats with adjuvant arthritis (AA) with CP-25. We found that the membrane EP4 protein level was downregulated;whereas, GRK2 was upregulated, inflbroblast-like synoviocyte (FLS)s of AA rats. Prostaglandin (PGE)2 stimulated FLS proliferation and enhanced the membrane EP4 receptor protein level;the latter was reversed by the administration of an EP4 receptor agonist, whereas the membrane GRK2 protein level gradually increased. The changes in the EP4 receptor and GRK2 expression were enhanced by TNF-α, and the former was accompanied by an alteration in the cyclic (c) AMP level. The EP4 receptor agonist stimulation increased the association between GRK2 and the EP4 receptor. GRK2 knockdown abrogated the abnormalities in FLS proliferation. The CP-25 treatment (100 mg/kg) suppressed joint infiammation with an efficacy that was similar to that of methotrexate. This finding was associated with EP4 upregulation and GRK2 downregulation in FLSs. Thus, GRK2 plays an important role in the abnormal FLS proliferation observed in AA possibly by promoting EP4 receptor desensitization and decreasing the cAMP level.

19Rare earth oxides and their supported noble metals in application of environmental catalysis显示文摘Volatile organic compounds(VOCs),methane,carbon monoxide,soot,automotive exhaust,and nitrogen oxides are harmful to the atmosphere and human health.It is urgent to strictly control their emissions.Heterogeneous catalysis is an effective pathway for the removal of these pollutants,and the critical issue is the development of novel and high-performance catalysts.In this review,we briefly summarize the preparation methods,physicochemical properties,catalytic activities,and related reaction mechanisms for the above pollutants removal of the rare earth oxides,mixed rare earth oxide,rare earth oxidesupported noble metal,and mixed rare earth oxide-supported noble metal catalysts that have been investigated by our group and other researchers.It was found that catalytic performance was associated with the factors,such as specific surface area,pore structure,particle size and dispersion,adsorbed oxygen species concentration,reducibility,reactant activation ability or interaction between metal nanoparticles and support.Furthermore,we also envision the development trend of such a topic in future work.Zhiquan Hou Wenbo Pei Xing Zhang Kunfeng Zhang Yuxi Liu Jiguang Deng Lin Jing Hongxing Dai 2020Journal of Rare Earths2020,38,8:10
20A novel anticancer property of Lycium barbarum polysaccharide in triggering ferroptosis of breast cancer cells显示文摘Breast cancer is one of the most malignant tumors and is associated with high mortality rates among women.Lycium barbarum polysaccharide(LBP)is an extract from the fruits of the traditional Chinese herb,L.barbarum.LBP is a promising anticancer drug,due to its high activity and low toxicity.Although it has anticancer properties,its mechanisms of action have not been fully established.Ferroptosis,which is a novel anticancer strategy,is a cell death mechanism that relies on iron-dependent lipid reactive oxygen species(ROS)accumulation.In this study,human breast cancer cells(Michigan Cancer Foundation-7(MCF-7)and MD Anderson-Metastatic Breast-231(MDA-MB-231))were treated with LBP.LBP inhibited their viability and proliferation in association with high levels of ferroptosis.Therefore,we aimed to ascertain whether LBP reduced cell viability through ferroptosis.We found that the structure and function of mitochondria,lipid peroxidation,and expression of solute carrier family 7 member 11(SLC7 A11,also known as x CT,the light-chain subunit of cystine/glutamate antiporter system X_(c)^(-))and glutathione peroxidase 4(GPX4)were altered by LBP.Moreover,the ferroptosis inhibitor,Ferrostatin-1(Fer-1),rescued LBP-induced ferroptosis-associated events including reduced cell viability and glutathione(GSH)production,accumulation of intracellular free divalent iron ions and malondialdehyde(MDA),and down-regulation of the expression of x CT and GPX4.Erastin(x CT inhibitor)and RSL3(GPX4 inhibitor)inhibited the expression of x CT and GPX4,respectively,which was lower after the co-treatment of LBP with Erastin and RSL3.These results suggest that LBP effectively prevents breast cancer cell proliferation and promotes ferroptosis via the x CT/GPX4 pathway.Therefore,LBP exhibits novel anticancer properties by triggering ferroptosis,and may be a potential therapeutic option for breast cancer.Xing DU Jingjing ZHANG Ling LIU Bo XU Hang HAN Wenjie DAI Xiuying PEI Xufeng FU Shaozhang HOU 2022Journal of Zhejiang University-Science B(Biomedicine & Biotechnology)2022,23,4:10
