1Exercise as a prescription for patients with various diseases显示文摘A growing understanding of the benefits of exercise over the past few decades has prompted researchers to take an interest in the possibilities of exercise therapy.Because each sport has its own set of characteristics and physiological complications that tend to occur during exercise training,the effects and underlying mechanisms of exercise remain unclear.Thus,the first step in probing the effects of exercise on different diseases is the selection of an optimal exercise protocol.This review summarizes the latest exercise prescription treatments for 26 different diseases:musculoskeletal system diseases(low back pain,tendon injury,osteoporosis,osteoarthritis,and hip fracture),metabolic system diseases(obesity,type 2 diabetes,type 1 diabetes,and nonalcoholic fatty liver disease),cardio-cerebral vascular system diseases(coronary artery disease,stroke,and chronic heart failure),nervous system diseases(Parkinson’s disease,Huntington’s disease,Alzheimer’s disease,depression,and anxiety disorders),respiratory system diseases(chronic obstructive pulmonary disease,interstitial lung disease,and after lung transplantation),urinary system diseases(chronic kidney disease and after kidney transplantation),and cancers(breast cancer,colon cancer,prostate cancer,and lung cancer).Each exercise prescription is displayed in a corresponding table.The recommended type,intensity,and frequency of exercise prescriptions are summarized,and the effects of exercise therapy on the prevention and rehabilitation of different diseases are discussed.Xin Luan Xiangyang Tian Haixin Zhang Rui Huang Na Li Peijie Chen Ru Wang 2019Journal of Sport and Health Science2019,8,5:61
2Current status of diagnosis and treatment of bladder cancer in China-Analyses of Chinese Bladder Cancer Consortium database显示文摘Objective:To investigate current status of diagnosis and treatment of bladder cancer in China.Methods:A database was generated by Chinese Bladder Cancer Consortium(CBCC).From January 2007 to December 2012,14,260 cases from 44 CBCC centers were included.Data of diagnosis,treatment and pathology were collected.Results:The average age was 63.5 year-old and most patients were male(84.3%).The most common histologic types were urothelial carcinoma(91.4%),adenocarcinoma(1.8%),and squamous carcinoma(1.9%).According to 1973 and 2004 WHO grading system,42.0%,41.0%,and 17.0% of patients were grade 1,2,and 3,and 16.0%,48.7%,and 35.3% of patients were papillary urothelial neoplasms of low malignant potential,low,and high grade,respectively.Non-muscle invasive bladder cancer(NMIBC)and muscle invasive bladder cancer(MIBC)were 25.2% and 74.1%,respectively(0.8% not clear).Carcinoma in situ was only 2.4%.Most patients were diagnosed by white-light cystoscopy with biopsy(74.3%).Fluorescence and narrow band imaging cystoscopy had additional detection rate of 1.0% and 4.0%,respectively.Diagnostic transurethral resection(TUR)provided detection rate of 16.9%.Most NMIBCs were treated with TUR(89.2%).After initial TUR,2.6%accepted second TUR,and 45.7%,69.9%,and 58.7% accepted immediate,induced,and maintenance chemotherapy instillation,respectively.Most MIBCs were treated with radical cystectomy(RC,59.7%).Laparoscopic RCs were 35.1%,while open RC 63.4%.Extended and standard pelvic lymph node dissection were 7% and 66%,respectively.Three most common urinary diversions were orthotopic neobladder(44%),ileal conduit(31%),and ureterocutaneostomy(23%).Only 2.3% of patients accepted neo-adjuvant chemotherapy and only 18%of T3 and T4 patients accepted adjuvant chemotherapy.Conclusion:Disease characteristics are similar to international reports,while differences of diagnosis and treatment exist.This study can provide evidences for revisions of the guideline on bladder cancer in China.Kaiwen Li Tianxin Lin Wei Xue Xin Mu Enci Xu Xu Yang Fubao Chen Guangyong Li Lulin Ma Guoliang Wang Chaozhao Liang Haoqiang Shi Ming Li Mao Tang Xueyi Xue Yisong Lv Yaoliang Deng Chengyang Li Zhiwen Chen Xiaozhou Zhou Fengshuo Jin Xudong Liu Jinxin Wei Lei Shi Xin Gou Weiyang He Liqun Zhou Lin Cai Baiye Jin Guanghou Fu Xiangbo Kong Hongyan Sun Ye Tian Lang Feng Tiejun Pan Yiyi Wu Dongwen Wang Hailong Hao Benkang Shi Yaofeng Zhu Qiang Wei Ping Han Changli Wu Dawei Tian Zhangqun Ye Zheng Liu Zhiping Wang Junqiang Tian Lin Qi Minfeng Chen Wei Li Jinchun Qi Gongxian Wang Longlong Fu Zhaolin Sun Guangheng Luo Zhoujun Shen Zhaowei Zhu Jinchun Xing Zhun Wu Dong Wei Xin Chen Yanqun Na Hongfeng Guo Chunxi Wang Zhihua Lu Chuize Kong Yang Liu Jin Yang Jianyun Hu Xin Gao Jielin Li Changjun Yin Pu Li Shan Chen Zhen Du Jiongming Li Yongji Yan Xu Zhang Shuang Huang Fangjian Zhou Zhiling Zhang Yinghao Sun Shuxiong Zeng Song Cen Jiaquan Zhou Hanzhong Li Jin Wen Jian Huang 2015Asian Journal of Urology2015,2,2:21
3Role of penehyclidine in acute organophosphorus pesticide poisoning显示文摘BACKGROUND:Penehyclidine is a newly developed anticholinergic agent.We aimed to investigate the role of penehyclidine in acute organophosphorus pesticide poisoning(OP)patients.METHODS:We searched the Pubmed,Cochrane library,EMBASE,Chinese National Knowledge Infrastructure(CNKI),Chinese Biomedical literature(CBM)and Wanfang databases.Randomized controlled trials(RCTs)recruiting acute OP patients were identifi ed for meta-analysis.Main outcomes included cure rate,mortality rate,time to atropinization,time to 60%normal acetylcholinesterase(AchE)level,rate of intermediate syndrome(IMS)and rate of adverse drug reactions(ADR).RESULTS:Sixteen RCTs involving 1,334 patients were identifi ed.Compared with the atropineor penehyclidine-alone groups,atropine combined with penehyclidine significantly increased the cure rate(penehyclidine+atropine vs.atropine,0.97 vs.0.86,RR 1.13,95%CI[1.07–1.19];penehyclidine+atropine vs.penehyclidine,0.93 vs.0.80,RR 1.08,95%CI[1.01–1.15])and reduced the mortality rate(penehyclidine+atropine vs.atropine,0.015 vs.0.11,RR 0.17,95%CI[0.06–0.49];penehyclidine+atropine vs.penehyclidine,0.13 vs.0.08,RR 0.23,95%CI[0.04–1.28]).Atropine combined with penehyclidine in OP patients also helped reduce the time to atropinization and AchE recovery,the rate of IMS and the rate of ADR.Compared with a single dose of atropine,a single dose of penehyclidine also signifi cantly elevated the cure rate,reduced times to atropinization,AchE recovery,and rate of IMS.CONCLUSION:Atropine combined with penehyclidine benefi ts OP patients by enhancing the cure rate,mortality rate,time to atropinization,AchE recovery,IMS rate,total ADR and duration of hospitalization.Penehyclidine combined with atropine is likely a better initial therapy for OP patients than atropine alone.Shi-yuan Yu Yan-xia Gao Joseph Walline Xin Lu Li-na Zhao Yuan-xu Huang Jiang Tao An-yong Yu Na Ta Ren-ju Xiao Yi Li 2020World Journal of Emergency Medicine2020,11,1:18
4Antioxidant and Anti-inflammatory Capacity of Ferulic Acid Released from Wheat Bran by Solid-state Fermentation of Aspergillus niger显示文摘Objective A strain of Aspergillus niger(A. niger), capable of releasing bound phenolic acids from wheat bran, was isolated. This strain was identified by gene sequence identification. The antioxidant and anti-inflammatory capacity of ferulic acid released from wheat bran by this A. niger strain(FA-WB) were evaluated. Methods Molecular identification techniques based on PCR analysis of specific genomic sequences were conducted; antioxidant ability was examined using oxygen radical absorbance capacity(ORAC), cellular antioxidant activity(CAA) assays, and erythrocyte hemolysis assays. RAW264.7 cells were used as a model to detect anti-inflammatory activity. Results The filamentous fungal isolate was identified to be A. niger. ORAC and CAA assay showed that FA-WB had better antioxidant activity than that of the ferulic acid standard. The erythrocyte hemolysis assay results suggested that FA-WB could attenuate AAPH-induced oxidative stress through inhibition of reactive oxy gen species(ROS) generation. FA-WB could significantly restore the AAPH-induced increase in intracellular antioxidant enzyme activities to normal levels as well as inhibit the intracellular malondialdehyde formation. TNF-?, IL-6, and NO levels indicated that FA-WB can inhibit the inflammation induced by lipopolysaccharide(LPS). Conclusion Ferulic acid released from wheat bran by a new strain of A. niger had good anti-inflammatory activity and better antioxidant ability than standard ferulic acid.YIN Zhi Na WU Wen Jia SUN Chong Zhen LIU Hui Fan CHEN Wen Bo ZHAN Qi Ping LEI Zhuo Gui XIN Xuan MA Juan Juan YAO Kun MIN Tian ZHANG Meng Meng WU Hui 2019Biomedical and Environmental Sciences2019,32,1:14
5The Qitai radio telescope显示文摘This study presents a general outline of the Qitai radio telescope(QTT)project.Qitai,the site of the telescope,is a county of Xinjiang Uygur Autonomous Region of China,located in the east Tianshan Mountains at an elevation of about 1800 m.The QTT is a fully steerable,Gregorian-type telescope with a standard parabolic main reflector of 110 m diameter.The QTT has adopted an umbrella support,homology-symmetric lightweight design.The main reflector is active so that the deformation caused by gravity can be corrected.The structural design aims to ultimately allow high-sensitivity observations from 150 MHz up to115 GHz.To satisfy the requirements for early scientific goals,the QTTwill be equipped with ultra-wideband receivers and large field-of-view multi-beam receivers.A multi-function signal-processing system based on RFSo C and GPU processor chips will be developed.These will enable the QTT to operate in pulsar,spectral line,continuum and Very Long Baseline Interferometer(VLBI)observing modes.Electromagnetic compatibility(EMC)and radio frequency interference(RFI)control techniques are adopted throughout the system design.The QTT will form a world-class observational platform for the detection of lowfrequency(nano Hertz)gravitational waves through pulsar timing array(PTA)techniques,pulsar surveys,the discovery of binary black-hole systems,and exploring dark matter and the origin of life in the universe.The QTT will also play an important role in improving the Chinese and international VLBI networks,allowing high-sensitivity and high-resolution observations of the nuclei of distant galaxies and gravitational lensing systems.Deep astrometric observations will also contribute to improving the accuracy of the celestial reference frame.Potentially,the QTT will be able to support future space activities such as planetary exploration in the solar system and to contribute to the search for extraterrestrial intelligence.Na Wang Qian Xu Jun Ma Zhiyong Liu Qi Liu Hailong Zhang Xin Pei Maozheng Chen Richard N.Manchester Kejia Lee Xingwu Zheng Hans J.Kärcher Wulin Zhao Hongwei Li Dongwei Li Martin Süss Matthias Reichert Zhongyi Zhu Congsi Wang Mingshuai Li Rui Li Ning Li Guljaina Kazezkhan Wenming Yan Gang Wu Lang Cui Ming Zhang Haitao Li 2023Science China(Physics,Mechanics & Astronomy)2023,66,8:14
6CXCR7/CXCL12 axis is involved in lymph node and liver metastasis of gastric carcinoma显示文摘AIM To investigate the role of CXC chemokine receptor(CXCR)-7 and CXCL12 in lymph node and liver metastasis of gastric carcinoma.METHODS In 160 cases of gastric cancer, the expression of CXCR7 and CXCL12 in tumor and matched tumoradjacent non-cancer tissues, in the lymph nodes around the stomach and in the liver was detected using immunohistochemistry to analyze the relationship between CXCR7/CXCL12 expression and clinicopathological features and to determine whether CXCR7 and CXCL12 constitute a biological axis to promote lymph node and liver metastasis of gastric cancer. Furthermore, the CXCR7 gene was silenced and overexpressed in human gastric cancer SGC-7901 cells, and cell proliferation, migration and invasiveness were measured by the MTT, wound healing and Transwell assays, respectively. RESULTS CXCR7 expression was up-regulated in gastric cancer tissues(P = 0.011). CXCR7/CXCL12 expression was significantly related to poor tumor differentiation, high tumor stage and lymph node(r = 0.338, P = 0.000) and liver metastasis(r = 0.629, P = 0.000). The expression of CXCL12 in lymph node and liver metastasis was higher than that in primary gastric cancer tissues(χ2 = 6.669, P = 0.010; χ2 = 25379, P = 0.000), and the expression of CXCL12 in lymph node and liver metastasis of gastric cancer was consistent with the positive expression of CXCR7 in primary gastric cancer(r = 0.338, P = 0.000; r = 0.629, P = 0.000). Overexpression of the CXCR7 gene promoted cell proliferation, migration and invasion. Silencing of the CXCR7 gene suppressed SGC-7901 cell proliferation, migration and invasion. Human gastric cancer cell lines expressed CXCR7 and showed vigorous proliferation and migratory responses to CXCL12.CONCLUSION The CXCR7/CXCL12 axis is involved in lymph node and liver metastasis of gastric cancer. CXCR7 is considered a potential therapeutic target for the treatment of gastric cancer.Qi Xin Na Zhang Hai-Bo Yu Qin Zhang Yan-Fen Cui Chuan-Shan Zhang Zhe Ma Yan Yang Wei Liu 2017World Journal of Gastroenterology2017,23,17:14

11Use of suppression subtractive hybridization strategy for cloning and identifying specifically expressed genes of renal cell carcinoma显示文摘Using suppression subtractive hybridization, a renal cell carcinoma (RCC) cDNA subtractive library which only contains differently expressed cDNAs between human RCC and normal kidney has been constructed. 200 clones were picked out randomly to perform enzyme digest analysis, a part of them underwent sequence analysis and Northern blot to identify RCC specially expressed genes. Results showed that 190 clones contain 50-400 bp inserts respectively. Sequence analysis was performed in 10 clones. All the 10 sequences were unknown before and derived from 6 unique novel genes among which the cDNA insert RCC18 has five copies. Northern blot analysis showed that RCC18 cDNA expressed highly in RCC, but there was no signal detected in normal kidney, and the full length of RCC18 was about 2.5 kb. The constructed cDNA subtractive library of human RCC is a highly efficient one and lays the solid foundation for large-scale screening and cloning new and specific oncogenes or tumor suppressor genes of RCC.

12Repeatability and Reproducibility of Quantitative Assessment of the Retinal Microvasculature Using Optical Coherence Tomography Angiography Based on Optical Microangiography显示文摘Objective The aim of this study was to determine the repeatability and reproducibility of optical coherence tomography angiography(OCTA) based on optical microangiography(OMAG) measurements of macular vessels in normal eyes. Methods In this prospective cohort study, 40 eyes of 40 healthy volunteers underwent repeated OCTA(Cirrus HD-OCT 5000 angiography system, Carl Zeiss Meditec, Inc.) scans on two separate visit days. On each visit day, the eyes were scanned three times. The following parameters were used to quantitatively describe the OCTA images of the superficial vascular network: vessel area density(VAD), vessel skeleton density(VSD), vessel diameter index(VDI), vessel perimeter index(VPI), vessel complexity index(VCI), flux, and foveal avascular zone(FAZ). Coefficient of variation(CV) and intraclass correlation coefficient(ICC) were calculated for evaluating intravisit and intervisit repeatability, as well as interobserver reproducibility. Results The measurements showed high repeatability [CVs ≤ 4.2%(intravisit) and ≤ 4.6%(intervisit)] and interobserver reproducibility(ICCs ≥ 0.923) for all parameters. Conclusion This study demonstrated good repeatability and reproducibility of OCTA based on OMAG for the measurement of superficial vessel parameters in normal eyes.ZHAO Qi YANG Wen Li WANG Xiao Na Ruikang K Wang YOU Qi Sheng CHU Zhong Di XIN Chen ZHANG Meng Yu LI Dong Jun WANG Zi Yang CHEN Wei LI Yi Feng CUI Rui SHEN Lin WEI Wen Bin 2018Biomedical and Environmental Sciences2018,31,6:8
13Ecological environment quality evaluation of the Sahel region in Africa based on remote sensing ecological index显示文摘Long-term monitoring of the ecological environment changes is helpful for the protection of the ecological environment.Based on the ecological environment of the Sahel region in Africa,we established a remote sensing ecological index(RSEI)model for this region by combining dryness,moisture,greenness,and desertification indicators.Using the Moderate-resolution Imaging Spectroradiometer(MODIS)data in Google Earth Engine(GEE)platform,this study analyzed the ecological environment quality of the Sahel region during the period of 2001-2020.We used liner regression and fluctuation analysis methods to study the trend and fluctuation of RSEI,and utilized the stepwise regression approach to analyze the contribution of each indicator to the RSEI.Further,the correlation analysis was used to analyze the correlation between RSEI and precipitation,and Hurst index was applied to evaluate the change trend of RSEI in the future.The results show that RSEI of the Sahel region exhibited spatial heterogeneity.Specifically,it exhibited a decrease in gradient from south to north of the Sahel region.Moreover,RSEI in parts of the Sahel region presented non-zonal features.Different land-cover types demonstrated different RSEI values and changing trends.We found that RSEI and precipitation were positively correlated,suggesting that precipitation is the controlling factor of RSEI.The areas where RSEI values presented an increasing trend were slightly less than the areas where RSEI values presented a decreasing trend.In the Sahel region,the areas with the ecological environment characterized by continuous deterioration and continuous improvement accounted for 44.02%and 28.29%of the total study area,respectively,and the areas in which the ecological environment was changing from improvement to deterioration and from deterioration to improvement accounted for 12.42%and 15.26%of the whole area,respectively.In the face of the current ecological environment and future change trends of RSEI in the Sahel region,the research results provide a reference for the construction of the'Green Great Wall'(GGW)ecological environment project in Africa.WU Shupu GAO Xin LEI Jiaqiang ZHOU Na GUO Zengkun SHANG Baijun 2022Journal of Arid Land2022,14,1:8
14Synergistic effects of Cu species and acidity of Cu-ZSM-5 on catalytic performance for selective catalytic oxidation of n-butylamine显示文摘In this work, a series of Cu-ZSM-5 catalysts with different SiO2/Al2O3 ratios(25, 50, 100 and200) were synthesized and investigated in n-butylamine catalytic degradation. The n-butylamine can be completely catalytic degradation at 350 ℃ over all Cu-ZSM-5 catalysts. Moreover, Cu-ZSM-5(25) exhibited the highest selectivity to N2, exceeding 90% at 350 ℃. These samples were investigated in detail by several characterizations to illuminate the dependence of the catalytic performance on redox properties, Cu species, and acidity. The characterization results proved that the redox properties and chemisorption oxygen primarily affect n-butylamine conversion. N2 selectivity was impacted by the Bronsted acidity and the isolated Cu^2+ species. Meanwhile, the surface acid sites over Cu-ZSM-5 catalysts could influence the formation of Cu species. Furthermore, in situ diffuse reflectance infrared Fourier transform spectra was adopted to explore the reaction mechanism. The Cu-ZSM-5 catalysts are the most prospective catalysts for nitrogen-containing volatile organic compounds removal, and the results in this study could provide new insights into catalysts design for VOC catalytic oxidation.Xin Xing Na Li Jie Cheng Yonggang Sun Zhongshen Zhang Xin Zhang Zhengping Hao 2020Journal of Environmental Sciences2020,32,10:7
15An Improved Barcoded Oligonucleotide Primers-based Next-generation Sequencing Approach for Direct Identification of Viral Pathogens in Clinical Specimens显示文摘Objective To provide a feasible and cost-effective next-generation sequencing(NGS) method for accurate identification of viral pathogens in clinical specimens, because enormous limitations impede the clinical use of common NGS, such as high cost, complicated procedures, tremendous data analysis, and high background noise in clinical samples. Methods Viruses from cell culture materials or clinical specimens were identified following an improved NGS procedure: reduction of background noise by sample preprocessing, viral enrichment by barcoded oligonucleotide(random hexamer or non-ribosomal hexanucleotide) primer-based amplification, fragmentation-free library construction and sequencing of one-tube mixtures, as well as rapid data analysis using an in-house pipeline. Results NGS data demonstrated that both barcoded primer sets were useful to simultaneously capture multiple viral pathogens in cell culture materials or clinical specimens and verified that hexanucleotide primers captured as many viral sequences as hexamers did. Moreover, direct testing of clinical specimens using this improved hexanucleotide primer-based NGS approach provided further detailed genotypes of enteroviruses causing hand, foot, and mouth disease(HFMD) and identified other potential viruses or differentiated misdiagnosis events. Conclusion The improved barcoded oligonucleotide primer-based NGS approach is simplified, time saving, cost effective, and appropriate for direct identification of viral pathogens in clinical practice.WANG Churl Hua NIE Kai ZHANG Yi WANG Ji ZHOU Shuai Feng LI Xin Na ZHOU Hang Yu QI Shun Xiang MA Xue Jun 2017Biomedical and Environmental Sciences2017,30,1:7
16Donepezil,a drug for Alzheimer’s disease,promotes oligodendrocyte generation and remyelination显示文摘Myelin sheaths play important roles in neuronal functions.In the central nervous system(CNS),the myelin is formed by oligodendrocytes(OLs),which are differentiated from oligodendrocyte precursor cells(OPCs).In CNS demyelinating disorders such as multiple sclerosis(MS),the myelin sheaths are damaged and the remyelination process is hindered.Small molecule drugs that promote OPC to OL differentiation and remyelination may provide a new way to treat these demyelinating diseases.Here we report that donepezil,an acetylcholinesterase inhibitor(AChEI)developed for the treatment of Alzheimer's disease(AD);significantly promotes OPC to OL differentiation.Interestingly,other AChEls,including huperzine A,rivastigmine,and tacrine,have no such effect indicating that donepezil's effect in promoting OPC differentiation is not dependent on the inhibition of AChE.Donepezil also facilitates the formation of myelin sheaths in OPC-DRG neuron co-culture.More interestingly,donepezil also promotes the repair of the myelin sheaths in vivo and provides significant therapeutic effect in a cuprizone-mediated demyelination animal model.Donepezil is a drug that has been used to treat AD safely for many years;our findings suggest that it might be repurposed to treat CNS demyelinating diseases such as MS by promoting OPC to OL differentiation and remyelination.Xue Cui Yu-e Guo Jia-hui Fang Chang-jie Shi Na Suo Ru Zhang Xin Xie 2019Acta Pharmacologica Sinica2019,40,11:7
17Detection of Human Bocavirus in Children with Acute Respiratory Tract Infections in Lanzhou and Nanjing,China显示文摘Objective The aim of this study was to explore the prevalent characteristics of HBoV1 and its co-infection.Methods PCR was used to detect HBoV1-DNA(HBoV1) and other viruses.A multivariate logistic regression model was used to explore possibility of co-detected for related viruses.Results The positivity rates in Nanjing and Lanzhou were 9.38%(74/789) and 11.62%(161/1386),respectively(P>0.05).The HBoV1 positive group was younger than negative group(P<0.05).Seasonal differences were noted,with a higher frequency of infection in December and July.HBoV1-positive children [72.34%(169/235)] were co-infected with other respiratory viruses.Multifactorial analysis showed no correlations between HBoV1 and the clinical classification,region,gender,age,or treatment as an outpatient or in a hospital.Correlations were identified between HBoV1 infections with ADV(OR=1.53,95% CI 1.03-2.28),RSV(OR=0.71,95% CI 0.52-0.98),and IFVA(OR=1.77,95% CI 1.00-3.13).Conclusions Presence of HBoV1 in nasopharyngeal aspirates did not correlate with region or gender,although the prevalence of HBoV1 was higher in younger children.There were no correlations between HBoV1 and other variables,except for the season and ADV,RSV,or IFVA infections.WU Jian Jun JIN Yu LIN Na XIE Zhi Ping YU Jie Mei LI Jin Song CAO Chang Qing YUAN Xin Hui SONG Jin Rong ZHANG Jing ZHAO Yang GAO Xiao Qian DUAN Zhao Jun 2014Biomedical and Environmental Sciences2014,27,11:7

19Acellular ostrich corneal stroma used as scaffold for construction of tissue-engineered cornea显示文摘AIM:To assess acellular ostrich corneal matrix used as a scaffold to reconstruct a damaged cornea.· METHODS:A hypertonic saline solution combined with a digestion method was used to decellularize the ostrich cornea.The microstructure of the acellular corneal matrix was observed by transmission electron microscopy(TEM) and hematoxylin and eosin(H&E) staining.The mechanical properties were detected by a rheometer and a tension machine.The acellular corneal matrix was also transplanted into a rabbit cornea and cytokeratin 3 was used to check the immune phenotype.·RESULTS:The microstructure and mechanical properties of the ostrich cornea were well preserved after the decellularization process.In vitro,the methyl thiazolyl tetrazolium results revealed that extracts of the acellular ostrich corneas(AOCs) had no inhibitory effects on the proliferation of the corneal epithelial or endothelial cells or on the keratocytes.The rabbit lamellar keratoplasty showed that the transplanted AOCs were transparent and completely incorporated into the host cornea while corneal turbidity and graft dissolution occurred in the acellular porcine cornea(APC) transplantation.The phenotype of the reconstructed cornea was similar to a normal rabbit cornea with a high expression of cytokeratin 3 in the superficial epithelial cell layer.· CONCLUSION:We first used AOCs as scaffolds to reconstruct damaged corneas.Compared with porcine corneas,the anatomical structures of ostrich corneas are closer to those of human corneas.In accordance with the principle that structure determines function,a xenograft lamellar keratoplasty also confirmed that the AOC transplantation generated a superior outcome compared to that of the APC graft.Xian-Ning Liu Xiu-Ping Zhu Jie Wu Zheng-Jie Wu Yong Yin Xiang-HuaXiao Xin Su Bin Kong Shi-Yin Pan Hua Yang Yan Cheng Na An Sheng-Li Mi 2016International Journal of Ophthalmology(English edition)2016,9,3:6
