1Coding metamaterials, digital metamaterials and programmable metamaterials显示文摘Metamaterials are artificial structures that are usually described by effective medium parameters on the macroscopic scale,and these metamaterials are referred to as‘analog metamaterials’.Here,we propose‘digital metamaterials’through two steps.First,we present‘coding metamaterials’that are composed of only two types of unit cells,with 0 and p phase responses,which we name‘0’and‘1’elements,respectively.By coding‘0’and‘1’elements with controlled sequences(i.e.,1-bit coding),we can manipulate electromagnetic(EM)waves and realize different functionalities.The concept of coding metamaterials can be extended from 1-bit coding to 2-bit coding or higher.In 2-bit coding,four types of unit cells,with phase responses of 0,p/2,p,and 3p/2,are required to mimic the‘00’,‘01’,‘10’and‘11’elements,respectively.The 2-bit coding has greater freedom than 1-bit coding for controlling EM waves.Second,we propose a unique metamaterial particle that has either a‘0’or‘1’response controlled by a biased diode.Based on this particle,we present‘digital metamaterials’with unit cells that possess either a‘0’or‘1’state.Using a field-programmable gate array,we realize digital control over the digital metamaterial.By programming different coding sequences,a single digital metamaterial has the ability to manipulate EM waves in different manners,thereby realizing‘programmable metamaterials’.The above concepts and physical phenomena are confirmed through numerical simulations and experiments using metasurfaces.Tie Jun Cui Mei Qing Qi Xiang Wan Jie Zhao Qiang Cheng 2014Light(Science & Applications)2014,3,1:130
22018 Chinese Pediatric Cardiology Society(CPCS) guideline for diagnosis and treatment of syncope in children and adolescents显示文摘Syncope belongs to the transient loss of consciousness(TLOC), characterized by a rapid onset, short duration, and spontaneous complete recovery. It is common in children and adolescents, accounting for 1% to 2% of emergency department visits.Recurrent syncope can seriously affect children's physical and mental health, learning ability and quality of life and sometimes cardiac syncope even poses a risk of sudden death. The present guideline for the diagnosis and treatment of syncope in children and adolescents was developed for guiding a better clinical management of pediatric syncope. Based on the globally recent development and the evidence-based data in China, 2018 Chinese Pediatric Cardiology Society(CPCS) guideline for diagnosis and treatment of syncope in children and adolescents was jointly prepared by the Pediatric Cardiology Society, Chinese Pediatric Society, Chinese Medical Association(CMA)/Committee on Pediatric Syncope, Pediatricians Branch, Chinese Medical Doctor Association(CMDA)/Committee on Pediatric Cardiology, Chinese College of Cardiovascular Physicians, Chinese Medical Doctor Association(CMDA)/Pediatric Cardiology Society, Beijing Pediatric Society, Beijing Medical Association(BMA). The present guideline includes the underlying diseases of syncope in children and adolescents, the diagnostic procedures, methodology and clinical significance of standing test and headup tilt test, the clinical diagnosis vasovagal syncope, postural orthostatic tachycardia syndrome, orthostatic hypotension and orthostatic hypertension, and the treatment of syncope as well as follow-up.Cheng Wang Yaqi Li Ying Liao Hong Tian Min Huang Xiangyu Dong Lin Shi Jinghui Sun Hongfang Jin Junbao Du Jindou An Jie Chen Mingwu Chen Qi Chen Sun Chen Yonghong Chen Zhi Chen Adolphus Kai-tung Chau Junbao Du Zhongdong Du Junkai Duan Hongyu Duan Xiangyu Dong Lin Feng Lijun Fu Fangqi Gong Yonghao Gui Ling Han Zhenhui Han Bing He Zhixu He Xiufen Hu Yimin Hua Guoying Huang Min Huang Ping Huang Yujuan Huang Hongfang Jin Mei Jin Bo Li Fen Li Tao Li Xiaohui Li Xiaoyan Liu Yan Li Haitao Lv Tiewei Lv Zipu Li Luyi Ma Silin Pan Yusheng Pang Hua Peng Yuming Qin Jie Shen Lin Shi Kun Sun Jinghui Sun Hong Tian Jie Tian Cheng Wang Hong Wang Lei Wang Jinju Wang Wendi Wang Yuli Wang Rongzhou Wu Tianhe Xia Yanyan Xiao Chunhong Xie Yanlin Xing Zhenyu Xiong Baoyuan Xu Yi Xu Hui Yan Shiwei Yang Qijian Yi Xia Yu Xianyi Yu Yue Yuan Hongyan Zhang Huili Zhang Li Zhang Qingyou Zhang Xi Zhang Yanmin Zhang Zhiwei Zhang Cuifen Zhao Bin Zhou Hua Zhu 2018Science Bulletin2018,63,23:54

5Comparison of Undernutrition Prevalence of Children under 5 Years in China between 2002 and 2013显示文摘Objective To describe the undernutrition status of children under 5-year in China, and study the trend between 2002 and 2013. Methods The study was based on two national surveys. Undernutrition was determined against WHO's 2006 growth standards. The prevalence in 2013 and 2002 was weighted by China sixth National Population Census(2010). The relationship between undernutrition and gender/age groups/different areas use weighted logistic regression. Results The results indicated the overall prevalence of stunting, underweight, and wasting of Chinese children under 5-year was 8.1%, 2.4%, and 1.9% in 2013, respectively. The prevalence of stunting was higher for children aged 12-47 month, while underweight was higher for children aged 48-59 month. The prevalence of undernutrition was higher in rural areas than in urban areas, especially in poor rural areas. There was a decline of stunting, underweight, and wasting between 2002 and 2013 among the children, with greater reduction in rural areas than in urban areas. Conclusion The prevalence of undernutrition of children under 5-year remains high in rural areas especially in poor rural areas in China. It is urgent to take action to control undernutrition in the vulnerable areas and subgroups.YU Dong Mei ZHAO Li Yun YANG Zhen Yu CHANG Su Ying YU Wen Tao FANG Hong Yun WANG Xun YU Dan GUO Qi Ya XU Xiao Li FANG Yue Hui ZHAO Wen Hua YANG Xiao Guang DING Gang Qiang LIANG Xiao Feng 2016Biomedical and Environmental Sciences2016,29,3:18
6Minimally invasive surgery alone compared with intensity-modulated radiotherapy for primary stage I nasopharyngeal carcinoma显示文摘Background:The National Comprehensive Cancer Network guidelines recommend intensity-modulated radiotherapy(IMRT)as the primary curative treatment for newly diagnosed nasopharyngeal carcinoma(NPC),but the radiation-related complications and relatively high medical costs remain a consequential burden for the patients.Endoscopic nasopharyngectomy(ENPG)was successfully applied in recurrent NPC with radiation free and relatively low medical costs.In this study,we examined whether ENPG could be an effective treatment for localized stage I NPC.Methods:Ten newly diagnosed localized stage I NPC patients voluntarily received ENPG alone from June 2007 to September 2017 in Sun Yat-sen University Cancer Center.Simultaneously,the data of 329 stage I NPC patients treated with IMRT were collected and used as a reference cohort.The survival outcomes,quality of life(QOL),and medical costs between two groups were compared.Results:After a median follow-up of 59.0 months(95%CI 53.4-64.6),no death,locoregional recurrence,or distant metastasis was observed in the 10 patients treated with ENPG.The 5-year overall survival,local relapse-free survival,regional relapse-free survival,and distant metastasis-free survival among the ENPG-treated patients was similar to that among the IMRT-treated patients(100%vs.99.1%,100%vs.97.7%,100%vs.99.0%,100%vs.97.4%,respectively,P>0.05).In addition,compared with IMRT,ENPG was associated with decreased total medical costs($4090.42±1502.65 vs.$12620.88±4242.65,P<0.001)and improved QOL scores including dry mouth(3.3±10.5 vs.34.4±25.8,P<0.001)and sticky saliva(3.3±10.5 vs.32.6±23.3,P<0.001).Conclusions:ENPG alone was associated with promising long-term survival outcomes,low medical costs,and satisfactory QOL and might therefore be an alternative strategy for treating newly diagnosed localized stage I NPC patients who refused radiotherapy.However,the application of ENPG should be prudent,and prospective clinical tri-als were needed to further verify the results.You-Ping Liu Xing Lv Xiong Zou Yi-Jun Hua Rui You Qi Yang Le Xia Shao-Yan Guo Wen Hu Meng-Xia Zhang Si-Yuan Chen Mei Lin Yu-Long Xie Li-Zhi Liu Rui Sun Pei-Yu Huang Wei Fan Xiang Guo Ming-Huang Hong Ming-Yuan Chen 2019Cancer Communications2019,39,1:17

8Treatment and outcomes of 1041 pediatric patients with neuroblastoma who received multidisciplinary care in China显示文摘Importance:Neuroblastoma is the most common extracranial malignant solid tumor in children.Multidisciplinary care is critical to improving the survival of pediatric patients with neuroblastoma.Objective:To systematically summarize the clinical characteristics of children with neuroblastoma and evaluate their prognosis with multidisciplinary care provided in a single center.Methods:This retrospective study analyzed the clinical data of 1041 patients with neuroblastoma who were diagnosed,treated,and followed-up in the Hematology-Oncology Center of Beijing Children’s Hospital from 2007 to 2019.Results:The median age at diagnosis was 34 months;80.8%of the patients were younger than 5 years of age.Notably,243 patients(23.3%)were classified as low-risk,249 patients(23.9%)were classified as intermediate-risk,and 549(52.7%)were classified as high-risk.Furthermore,956 patients underwent surgical resections;986(94.7%)patients received chemotherapy;and 176 patients with high-risk neuroblastoma received hematopoietic stem cell transplantation.The 5-year event-free survival(EFS)rate was 91.3%and 5-year overall survival(OS)rate was 97.5%in low-risk group;in the intermediate-risk group,these rates were 85.1%and 96.7%,respectively,while they were 37.7%and 48.9%in the high-risk group(P<0.001 for both).The 5-year EFS and OS rates were significantly higher in patients diagnosed between 2015 and 2019 than in patients diagnosed between 2007 and 2014(P<0.001).In total,278 patients(26.7%)exhibited tumor relapse or progression;the median interval until relapse or progression was 14 months.Of the 233 patients who died,83%died of relapse or progression of neuroblastoma and 4.3%died of therapy-related complications.Interpretation:The 5-year OS rate was low in high-risk patients,compared with low-and intermediate-risk patients.Multidisciplinary care is critical for improvement of survival in pediatric patients with neuroblastoma.Additional treatment strategies should be sought to improve the prognosis of patients with high-risk neuroblastoma.Yan Su Hong Qin Chenghao Chen Shengcai Wang Shihan Zhang Dawei Zhang Mei Jin Yun Peng Lejian He Xiaoman Wang Suyun Qian Maoquan Qin Ming Ge Fuquan Zhang Qi Zeng Huanmin Wang Xiaoli Ma Xin Ni 2020Pediatric Investigation2020,4,3:16
9Ciliary 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
10Association of Optic Radiation Integrity with Cortical Thickness in Children with Anisometropic Amblyopia显示文摘Previous studies have indicated regional abnormalities of both gray and white matter in amblyopia.However, alterations of cortical thickness associated with changes in white matter integrity have rarely been reported.In this study, structural magnetic resonance imaging and diffusion tensor imaging(DTI) data were obtained from 15 children with anisometropic amblyopia and 15 age- and gender-matched children with normal sight. Combining DTI and surface-based morphometry, we examined a potential linkage between disrupted white matter integrity and altered cortical thickness. The fractional anisotropy(FA) values in the optic radiations(ORs) of children with anisometropic amblyopia were lower than in controls(P \ 0.05). The cortical thickness in amblyopic children was lower than controls in the following subregions: lingual cortex, lateral occipitotemporal gyrus, cuneus, occipital lobe, inferior parietal lobe, and temporal lobe(P \ 0.05, corrected), but was higher in the calcarine gyrus(P \ 0.05, corrected). Node-by-node correlation analysis of changes in cortical thickness revealed a significant association between a lower FA value in the OR and diminished cortical thickness in the following subregions:medial lingual cortex, lateral occipitotemporal gyrus, lateral, superior, and medial occipital cortex, and lunate cortex. We also found a relationship between changes of cortical thickness and white matter OR integrity in amblyopia. These findings indicate that developmental changes occur simultaneously in the OR and visual cortex in amblyopia, and provide key information on complex damage of brain networks in anisometropic amblyopia. Our results also support the hypothesis that the pathogenesis of anisometropic amblyopia is neurodevelopmental.Shun Qi Yun-Feng Mu Long-Biao Cui Rong Li Mei Shi Ying Liu Jun-Qing Xu Jian Zhang Jian Yang Hong Yin 2016Neuroscience Bulletin2016,32,1:12
11A curative-intent endoscopic surgery for postradiation nasopharyngeal necrosis in patients with nasopharyngeal carcinoma显示文摘Background:Postradiation nasopharyngeal necrosis(PRNN)is a severe complication after radiotherapy in patients with nasopharyngeal carcinoma(NPC),which can severely affect the quality of life and threaten the patient’s life.Only 13.4%-28.6%of patients can be cured by traditional repeated endoscopic debridement.Here,we introduced an innovative curative-intent endoscopic surgery for PRNN patients and evaluated its clinical efficacy.Methods:Clinical data of 72 PRNN patients who underwent radical endoscopic necrectomy,followed by reconstruc-tion using a posterior pedicle nasal septum and floor mucoperiosteum flap were analyzed to determine the efficacy of this surgery.The endpoints were complete re-epithelialization of the nasopharyngeal defect,relief of headache,and overall survival(OS).Results:All surgeries were successfully performed without any severe postoperative complications or death.The median value of numeric rating scales of pain decreased from 8 before surgery to 0 after surgery(P<0.001).Fifty-one patients(70.8%)achieved complete re-epithelialization of the nasopharyngeal defect.The number of cycles of radiotherapy(odds ratio[OR],7.254;95%confidence interval[CI]1.035-50.821;P=0.046),postoperative pathological result(OR,34.087;95%CI 3.168-366.746;P=0.004),and survival status of flap(OR,261.179;95%CI 17.176-3971.599;P<0.001)were independent risk factors of re-epithelialization of the nasopharyngeal defects.Postoperative patho-logical result(hazard ratio[HR],5.018;95%CI 1.970-12.782;P=0.001)was an independent prognostic factor for OS.The 2-year OS rate of the entire cohort was 77.9%.Conclusion:Curative-intent endoscopic necrectomy followed by construction using the posterior pedicle nasal septum and floor mucoperiosteum flap is a novel,safe,and effective treatment of PRNN in patients with NPC.Xiong Zou Shun-Lan Wang You-Ping Liu Yan-Ling Liu Ru-Hai Zou Yi-Nuan Zhang Rui You Qi Yang Yu-Long Xie Mei Lin Pei-Yu Huang Rou Jiang Meng-Xia Zhang Chao-Nan Qian Hai-Qiang Mai Ling Guo Ming-Huang Hong Ming-Yuan Chen 2018Cancer Communications2018,38,1:11
12Anti-inflammatory activity of curcumin-loaded tetrahedral framework nucleic acids on acute gouty arthritis显示文摘Gouty arthritis is a very familiar inflammatory arthritis.Controlling inflammation is the key to preventing gouty arthritis.However,colchicine,the most highly represented drug used in clinical practice,has strict contraindications owing to some severe side effects.Curcumin(Cur),a natural anti-inflammatory drug,has demonstrated good safety and efficacy.However,the rapid degradation,poor aqueous solubility,and low bioavailability of Cur limit its therapeutic effect.To strengthen the effectiveness and bioavailability of Cur.Cur loaded tetrahedral framework nucleic acids(Cur-TFNAs)were synthesized to deliver Cur.Compared with free Cur,Cur-TFNAs exhibit a preferable drug stability,good biocompatibility(CCK-8 assay),ease of uptake(immunofluorescence),and higher tissue utilization(in vivo biodistribution).Most importantly,Cur-TFNAs present better anti-inflammatory effect than free Cur both in vivo and in vitro experiments through the determination of inflammation-related cytokines expression.Therefore,we believe that Cur-TFNAs have great prospects for the prevention of gout and similar inflammatory diseases.Mei Zhang Xiaolin Zhang Taoran Tian Qi Zhang Yuting Wen Junyao Zhu Dexuan Xiao Weitong Cui Yunfeng Lin 2022Bioactive Materials2022,7,2:10

14Clinical and genetic findings in a Chinese family with VDR-associated hereditary vitamin D-resistant rickets显示文摘Hereditary vitamin D-resistant rickets(HVDRR) is a rare autosomal recessive disorder characterized by severe rickets,hypocalcemia,hypophosphatemia,secondary hyperparathyroidism,and elevated alkaline phosphatase.This disorder is caused by homogeneous or heterogeneous mutations affecting the function of the vitamin D receptor(VDR),which lead to complete or partial target organ resistance to the action of 1,25-dihydroxy vitamin D.A non-consanguineous family of Chinese Han origin with one affected individual demonstrating HVDRR was recruited,with the proband evaluated clinically,biochemically and radiographically.To identify the presence of mutations in the VDR gene,all the exons and exon–intron junctions of the VDR gene from all family members were amplified using PCR and sequenced.The proband showed rickets,progressive alopecia,hypocalcemia,hypophosphatemia,secondary hyperparathyroidism,and elevated alkaline phosphatase.She also suffered from epilepsy,which is rarely seen in patients with HVDRR.Direct sequencing analysis revealed a homozygous missense mutation c.122G4A(p.C41Y) in the VDR gene of the proband,which is located in the first zinc finger of the DNA-binding domain.Both parents had a normal phenotype and were found to be heterozygous for this mutation.We report a Chinese Han family with one individual affected with HVDRR.A homozygous missense mutation c.122G4A(p.C41Y) in the VDR gene was found to be responsible for the patient's syndrome.In contrast to the results of treatment of HVDRR in other patients,our patient responded well to a supplement of oral calcium and a low dose of calcitriol.Qianqian Pang Xuan Qi Yan Jiang Ou Wang Mei Li Xiaoping Xing Jin Dong Weibo Xia 2016Bone Research2016,4,1:9

16A novel miR167a-OsARF6-OsAUX3 module regulates grain length and weight in rice显示文摘Grain size is one of the most important factors that control rice yield,as it is associated with grain weight(GW).To date,dozens of rice genes that regulate grain size have been isolated;however,the regulatory mechanism underlying GW control is not fully understood.Here,the quantitative trait locus qGL5 for grain length(GL)and GW was identified in recombinant inbred lines of 9311 and Nipponbare(NPB)and fine mapped to a candidate gene,OsAUX3.Sequence variations between 9311 and NPB in the OsAUX3 promoter and loss of function of OsAUX3 led to higher GL and GW.RNA sequencing,gene expression quantification,dual-luciferase reporter assays,chromatin immunoprecipitation-quantitative PCR,and yeast one-hybrid assays demonstrated that OsARF6 is an upstream transcription factor regulating the expression of OsAUX3.OsARF6 binds directly to the auxin response elements of the OsAUX3 promoter,covering a single-nucleotide polymorphism site between 9311 and NPB/Dongjin/Hwayoung,and thereby controls GL by altering longitudinal expansion and auxin distribution/content in glume cells.Furthermore,we showed that miR167a positively regulate GL and GW by directing OsARF6 mRNA silencing.Taken together,our study reveals that a novel miR167a-OsARF6-OsAUX3 module regulates GL and GW in rice,providing a potential target for the improvement of rice yield.Jiyue Qiao Hongzhen Jiang Yuqing Lin Lianguang Shang Mei Wang Dongming Li Xiangdong Fu Markus Geisler Yanhua Qi Zhenyu Gao Qian Qian 2021Molecular Plant2021,14,10:8
17Malnutrition 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
18Nerve regeneration factor promotes nerve regeneration in rat显示文摘Nerve regeneration factor (NRF) extracted from an oral liquid of traditional Chinese medicine, as a nerve growth decoction has been reported by previous studies to exert effects of promoting nerve growth and preventing neuron apoptosis. For new insights into the function of NRF on primary cultured neurons, we investigated the neurite outgrowth in cultured rat dorsal root ganglion (DRG) explant treated with NRF by immunofluorescence and the gene and protein expressions of neurofilament-H(NF-H) and growth associated protein 43 (GAP43) in the cultured rat DRG neurons by real-time quantitative RT-PCR and Western blotting, respectively. In addition, we used a rat model of sciatic nerve crush to evaluate the effect of NRF on regeneration of injured sciatic nerve by a combination of walk track analysis, electrophysiological and histological assessments. The in vitro experiments indicated that NRF promoted the neurite growth of DRGs and the expression of NF-H and GAP43 at mRNA and protein levels in DRG neurons, and in vivo experiments showed that NRF improved peripheral nerve regeneration and functional recovery.ZHANG Qi LIU Mei ZHOU Mingming DING Fei 2006Progress in Natural Science:Materials International2006,16,12:8
19Association of Overlapped and Un-overlapped Comorbidities with COVID-19 Severity and Treatment Outcomes: A Retrospective Cohort Study from Nine Provinces in China显示文摘Objective Several COVID-19 patients have overlapping comorbidities. The independent role of each component contributing to the risk of COVID-19 is unknown, and how some non-cardiometabolic comorbidities affect the risk of COVID-19 remains unclear.Methods A retrospective follow-up design was adopted. A total of 1,160 laboratory-confirmed patients were enrolled from nine provinces in China. Data on comorbidities were obtained from the patients’ medical records. Multivariable logistic regression models were used to estimate the odds ratio(OR) and 95% confidence interval(95% CI) of the associations between comorbidities(cardiometabolic or non-cardiometabolic diseases), clinical severity, and treatment outcomes of COVID-19.Results Overall, 158(13.6%) patients were diagnosed with severe illness and 32(2.7%) had unfavorable outcomes. Hypertension(2.87, 1.30–6.32), type 2 diabetes(T2 DM)(3.57, 2.32–5.49),cardiovascular disease(CVD)(3.78, 1.81–7.89), fatty liver disease(7.53, 1.96–28.96), hyperlipidemia(2.15, 1.26–3.67), other lung diseases(6.00, 3.01–11.96), and electrolyte imbalance(10.40, 3.00–26.10)were independently linked to increased odds of being severely ill. T2 DM(6.07, 2.89–12.75), CVD(8.47,6.03–11.89), and electrolyte imbalance(19.44, 11.47–32.96) were also strong predictors of unfavorable outcomes. Women with comorbidities were more likely to have severe disease on admission(5.46,3.25–9.19), while men with comorbidities were more likely to have unfavorable treatment outcomes(6.58, 1.46–29.64) within two weeks.Conclusion Besides hypertension, diabetes, and CVD, fatty liver disease, hyperlipidemia, other lung diseases, and electrolyte imbalance were independent risk factors for COVID-19 severity and poor treatment outcome. Women with comorbidities were more likely to have severe disease, while men with comorbidities were more likely to have unfavorable treatment outcomes.MA Yan ZHU Dong Shan CHEN Ren Bo SHI Nan Nan LIU Si Hong FAN Yi Pin WU Gui Hui YANG Pu Ye BAI Jiang Feng CHEN Hong CHEN Li Ying FENG Qiao GUO Tuan Mao HOU Yong HU Gui Fen HU Xiao Mei HU Yun Hong HUANG Jin HUANG Qiu Hua HUANG Shao Zhen JI Liang JIN Hai Hao LEI Xiao LI Chun Yan LI Min Qing LI Qun Tang LI Xian Yong LIU Hong De LIU Jin Ping LIU Zhang MA Yu Ting MAO Ya MO Liu Fen NA Hui WANG Jing Wei SONG Fang Li SUN Sheng WANG Dong Ting WANG Ming Xuan WANG Xiao Yan WANG Yin Zhen WANG Yu Dong WU Wei WU Lan Ping XIAO Yan Hua XIE Hai Jun XU Hong Ming XU Shou Fang XUE Rui Xia YANG Chun YANG Kai Jun YUAN Sheng Li ZHANG Gong Qi ZHANG Jin Bo ZHANG Lin Song ZHAO Shu Sen ZHAO Wan Ying ZHENG Kai ZHOU Ying Chun ZHU Jun Teng ZHU Tian Qing ZHANG Hua Min WANG Yan Ping WANG Yong Yan 2020Biomedical and Environmental Sciences2020,33,12:8
