1Human umbilical cord mesenchymal stem cells promote peripheral nerve repair via paracrine mechanisms显示文摘Human umbilical cord-derived mesenchymal stem cells(h UCMSCs) represent a promising young-state stem cell source for cell-based therapy. h UCMSC transplantation into the transected sciatic nerve promotes axonal regeneration and functional recovery. To further clarify the paracrine effects of h UCMSCs on nerve regeneration, we performed human cytokine antibody array analysis, which revealed that h UCMSCs express 14 important neurotrophic factors. Enzyme-linked immunosorbent assay and immunohistochemistry showed that brain-derived neurotrophic factor, glial-derived neurotrophic factor, hepatocyte growth factor, neurotrophin-3, basic fibroblast growth factor, type I collagen, fibronectin and laminin were highly expressed. Treatment with h UCMSC-conditioned medium enhanced Schwann cell viability and proliferation, increased nerve growth factor and brain-derived neurotrophic factor expression in Schwann cells, and enhanced neurite growth from dorsal root ganglion explants. These findings suggest that paracrine action may be a key mechanism underlying the effects of h UCMSCs in peripheral nerve repair.Zhi-yuan Guo Xun Sun Xiao-long Xu Qing Zhao Jiang Peng Yu Wang 2015Neural Regeneration Research2015,10,4:26
2Epidemiological Survey of the Prevalence of Non-fatal Injury among Children Aged 5-14 Years in China显示文摘Objective To determine the prevalence of non-fatal injuries among children aged 5-14 years in China.Methods Data of 21 973 children aged 5-14 years were extracted from the Fourth National Health Service Survey of China carried out between June 15 and July 10,2008.Injury-related indicators included:history of ever having had an injury,and injury frequency,cause,location and severity.Results The overall prevalence of non-fatal injuries among the children in the previous 12 months was 17.0 per 1000 subjects.The leading causes of non-fatal injuries were falls,animal bites,traffic accidents,falling objects and burns.The majority of children sustained only one injury.The main place of injury was at home in 40% and 54% of urban boys and girls,respectively,at school in 48% of rural boys,and at home and at school each in 33% of rural girls.Medical treatment for one day was the main option for 80% of urban boys and girls,84% of rural boys,and 72% of rural girls.Conclusion Nonfatal injuries among children aged 5-14 years are a serious public health concern in China.HU Ming HU Guo Qing SUN Zhen Qiu HE Xiang 2012Biomedical and Environmental Sciences2012,25,4:18
3A Chromosome-Level Genome Assembly of Garlic (Allium sativum) Provides Insights into Genome Evolution and Allicin Biosynthesis显示文摘Garlic,an economically important vegetable,spice,and medicinal crop,produces highly enlarged bulbs and unique organosulfur compounds.Here,we report a chromosome-level genome assembly for garlic,with a total size of approximately 16.24 Gb,as well as the annotation of 57561 predicted protein-coding genes,making garlic the first Allium species with a sequenced genome.Analysis of this garlic genome assembly reveals a recent burst of transposable elements,explaining the substantial expansion of the garlic genome.We examined the evolution of certain genes associated with the biosynthesis of allicin and inulin neoseries-type fructans,and provided new insights into the biosynthesis of these two compounds.Furthermore,a large-scale transcriptome was produced to characterize the expression patterns of garlic genes in different tissues and at various growth stages of enlarged bulbs.The reference genome and large-scale transcriptome data generated in this study provide valuable new resources for research on garlic biology and breeding.Xiudong Sun Siyuan Zhu Ningyang Li Yi Cheng Jing Zhao Xuguang Qiao Li Lu Shiqi Liu Yanzhou Wang Chan Liu Benping Li Wu Guo Shuang Gao Zemao Yang Fu Li Zheng Zeng Qing Tang Yupeng Pan Mengjiao Guan Jian Zhao Xiaomi ng Lu Huanwe n Meng Zhenlin Han Chun she ng Gao Wenkai Jiang Xing Zhao Shilin Tian Jianguang Su Zhihui Cheng Touming Liu 2020Molecular Plant2020,13,9:14

5Locoregional radiotherapy in patients with distant metastases of nasopharyngeal carcinoma at diagnosis显示文摘Systemic chemotherapy is the basic palliative treatment for metastatic nasopharyngeal carcinoma(NPC); however, it is not known whether locoregional radiotherapy targeting the primary tumor and regional lymph nodes affects the survival of patients with metastatic NPC. Therefore, we aimed to retrospectively evaluate the benefits of locoregional radiotherapy. A total of 408 patients with metastatic NPC were included in this study. The mortality risks of the patients undergoing supportive treatment and those undergoing chemotherapy were compared with that of patients undergoing locoregional radiotherapy delivered alone or in combination with chemotherapy. Univariate and multivariate analyses were conducted. The contributions of independent factors were assessed after adjustment for covariates with significant prognostic associations (P<0.05). Both locoregional radiotherapy and systemic chemotherapy were identified as significant independent prognostic factors of overall survival(OS). The mortality risk was similar in the group undergoing locoregional radiotherapy alone and the group undergoing systemic chemotherapy alone [multi-adjusted hazard ratio(HR)=0.9, P=0.529]; this risk was 60% lower than that of the group undergoing supportive treatment(HR=0.4, P=0.004) and 130% higher than that of the group undergoing both systemic chemotherapy and locoregional radiotherapy(HR=2.3, P<0.001). In conclusion, locoregional radiotherapy, particularly when combined with systemic chemotherapy, is associated with improved survival of patients with metastatic NPC.Ming-Yuan Chen Rou Jiang Ling Guo Xiong Zou Qing Liu Rui Sun Fang Qiu Zhong-Jun Xia Hui-Qiang Huang Li Zhang Ming-Huang Hong Hai-Qiang Mai Chao-Nan Qian 2013Chinese Journal of Cancer2013,32,11:13

7Diagnostic value of 5 serum biomarkers for hepatocellular carcinoma with different epidemiological backgrounds:A large-scale,retrospective study显示文摘Objective:Hepatocellular carcinoma(HCC)is a lethal global disease that requires an accurate diagnosis.We assessed the potential of 5 serum biomarkers(AFP,AFU,GGT-II,GPC3,and HGF)in the diagnosis of HCC.Methods:In this retrospective study,we measured the serum levels of each biomarker using ELISAs in 921 participants,including 298 patients with HCC,154 patients with chronic hepatitis(CH),122 patients with liver cirrhosis(LC),and 347 healthy controls from 3 hospitals.Patients negative for hepatitis B surface antigen and hepatitis C antibody(called'NBNC-HCC')and patients positive for the above indices(called'HBV-HCC and HCV-HCC')were enrolled.The selected diagnostic model was constructed using a training cohort(n=468),and a validation cohort(n=453)was used to validate our results.Receiver operating characteristic analysis was used to evaluate the diagnostic accuracy.Results:Theα-L-fucosidase(AFU)/α-fetoprotein(AFP)combination was best able to distinguish NBNC-HCC[area under the curve:0.986(95%confidence interval:0.958–0.997),sensitivity:92.6%,specificity:98.9%]from healthy controls in the test cohort.For screening populations at risk of developing HCC(CH and LC),the AFP/AFU combination improved the diagnostic specificity for early-stage HCC[area under the curve:0.776(0.712–0.831),sensitivity:52.5%,specificity:91.6%in the test group].In all-stage HBV-HCC and HCV-HCC,AFU was also the best candidate biomarker combined with AFP[area under the curve:0.835(0.784–0.877),sensitivity 69.1%,specificity:87.4%in the test group].All results were verified in the validation group.Conclusions:The AFP/AFU combination could be used to identify NBNC-HCC from healthy controls and hepatitis-related HCC from at-risk patients.Dongming Liu Yi Luo Lu Chen Liwei Chen Duo Zuo Yueguo Li Xiaofang Zhang Jing Wu Qing Xi Guangtao Li Lisha Qi Xiaofen Yue Xiehua Zhang Zhuoyu Sun Ning Zhang Tianqiang Song Wei Lu Hua Guo 2021Cancer Biology & Medicine2021,18,1:10
8Screening of Serum Biomarkers for Distinguishing between Latent and Active Tuberculosis Using Proteome Microarray显示文摘Objective To identify potential serum biomarkers for distinguishing between latent tuberculosis infection(LTBI) and active tuberculosis(TB). Methods A proteome microarray containing 4,262 antigens was used for screening serum biomarkers of 40 serum samples from patients with LTBI and active TB at the systems level. The interaction network and functional classification of differentially expressed antigens were analyzed using STRING 10.0 and the TB database, respectively. Enzyme-linked immunosorbent assays(ELISA) were used to validate candidate antigens further using 279 samples. The diagnostic performances of candidate antigens were evaluated by receiver operating characteristic curve(ROC) analysis. Both antigen combination and logistic regression analysis were used to improve diagnostic ability. Results Microarray results showed that levels of 152 Mycobacterium tuberculosis(Mtb)-antigenspecific IgG were significantly higher in active TB patients than in LTBI patients(P < 0.05), and these differentially expressed antigens showed stronger associations with each other and were involved in various biological processes. Eleven candidate antigens were further validated using ELISA and showed consistent results in microarray analysis. ROC analysis showed that antigens Rv2031 c, Rv1408, and Rv2421 c had higher areas under the curve(AUCs) of 0.8520, 0.8152, and 0.7970, respectively. In addition, both antigen combination and logistic regression analysis improved the diagnostic ability. Conclusion Several antigens have the potential to serve as serum biomarkers for discrimination between LTBI and active TB.CAO Shu Hui CHEN Yan Qing SUN Yong LIU Yang ZHENG Su Hua ZHANG Zhi Guo LI Chuan You 2018Biomedical and Environmental Sciences2018,31,7:8
9Association 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
10Efficacy and safety of Shenyankangfu Tablet,a Chinese patent medicine,for primary glomerulonephritis:A multicenter randomized controlled trial显示文摘Background:Shenyankangfu Tablet(SYKFT)is a Chinese patent medicine that has been used widely to decrease proteinuria and the progression of chronic kidney disease.Objective:This trial compared the efficacy and safety of SYKFT,for the control of proteinuria in primary glomerulonephritis patients,against the standard drug,losartan potassium.Design,setting,participants and intervention:This was a multicenter,double-blind,randomized,controlled clinical trial.Primary glomerulonephritis patients,aged 18-70 years,with blood pressure≤140/90 mmHg,estimated glomerular filtration rate(eGFR)>45 mL/min per 1.73 ㎡,and 24-hour proteinuria level of 0.5-3.0 g,were recruited in 41 hospitals across 19 provinces in China and were randomly divided into five groups:SYKFT,losartan potassium 50 mg or 100 mg,SYKFT plus losartan potassium 50 mg or 100 mg.Main outcome measu res:The primary outcome was change in the 24-hour proteinuria level,after 48 weeks of treatment.Results:A total of 735 participants were enrolled.The percent decline of urine protein quantification in the SYKFT group after 48 weeks was 8.78%±2.56%(P=0.006)more than that in the losartan 50 mg group,which was 0.51%±2.54%(P=1.000)less than that in the losartan 100 mg group.Compared with the losartan potassium 50 mg group,the SYKFT plus losartan potassium 50 mg group had a 13.39%±2.49%(P<0.001)greater reduction in urine protein level.Compared with the losartan potassium 100 mg group,the SYKFT plus losartan potassium 100 mg group had a 9.77%±2.52%(P=0.001)greater reduction in urine protein.With a superiority threshold of 15%,neither was statistically significant.eGFR,serum creatinine and serum albumin from the baseline did not change statistically significant.The average change in TCM syndrome score between the patients who took SYKFT(-3.00[-6.00,-2.00])and who did not take SYKFT(-2.00[-5.00,0])was statistically significant(P=0.003).No obvious adverse reactions were observed in any group.Conclusion:SYKFT decreased the proteinuria and improved the TCM syndrome scores of primary glomerulonephritis patients,with no change in the rate of decrease in the eGFR.SYKFT plus losartan potassium therapy decreased proteinuria more than losartan potassium therapy alone.Trial registration number:NCT02063100 on ClinicalTrials.gov.Jie Wu Shu-wei Duan Hong-tao Yang Yue-yi Deng Wei Li Ya-ni He Zhao-hui Ni Yong-li Zhan Shan Lin Zhi-yong Guo Jun Zhu Jing-ai Fang Xu-sheng Liu Li-hua Wang Rong Wang Nian-song Wang Xiao-hong Cheng Li-qun He Ping Luo Shi-ren Sun Ji-feng Sun Ai-ping Yin Geng-ru Jiang Hong-yu Chen Wen-hu Liu Hong-li Lin Meng Liang Lu Ma Ming Chen Li-qun Song Jian Chen Qing Zhu Chang-ying Xing Yun Li Ji-ning Gao Rong-shan Li Ying Li Hao Zhang Ying Lu Qiao-ling Zhou Jun-zhou Fu Qiang He Guang-yan Cai Xiang-mei Chen 2021Journal of Integrative Medicine2021,19,2:8
11Extracellular matrix from human umbilical cordderived mesenchymal stem cells as a scaffold for peripheral nerve regeneration显示文摘The extracellular matrix,which includes collagens,laminin,or fibronectin,plays an important role in peripheral nerve regeneration.Recently,a Schwann cell-derived extracellular matrix with classical biomaterial was used to mimic the neural niche.However,extensive clinical use of Schwann cells remains limited because of the limited origin,loss of an autologous nerve,and extended in vitro culture times.In the present study,human umbilical cord-derived mesenchymal stem cells(h UCMSCs),which are easily accessible and more proliferative than Schwann cells,were used to prepare an extracellular matrix.We identified the morphology and function of h UCMSCs and investigated their effect on peripheral nerve regeneration.Compared with a non-coated dish tissue culture,the h UCMSC-derived extracellular matrix enhanced Schwann cell proliferation,upregulated gene and protein expression levels of brain-derived neurotrophic factor,glial cell-derived neurotrophic factor,and vascular endothelial growth factor in Schwann cells,and enhanced neurite outgrowth from dorsal root ganglion neurons.These findings suggest that the h UCMSC-derived extracellular matrix promotes peripheral nerve repair and can be used as a basis for the rational design of engineered neural niches.Bo Xiao Feng Rao Zhi-yuan Guo Xun Sun Yi-guo Wang Shu-yun Liu Ai-yuan Wang Quan-yi Guo Hao-ye Meng Qing Zhao Jiang Peng Yu Wang Shi-bi Lu 2016Neural Regeneration Research2016,11,7:8
12X-ray-activated long persistent phosphors featuring strong UVC afterglow emissions显示文摘Phosphors emitting visible and near-infrared persistent luminescence have been explored extensively owing to their unusual properties and commercial interest in their applications such as glow-in-the-dark paints,optical information storage,and in vivo bioimaging.However,no persistent phosphor that features emissions in the ultraviolet C range(200–280 nm)has been known to exist so far.Here,we demonstrate a strategy for creating a new generation of persistent phosphor that exhibits strong ultraviolet C emission with an initial power density over 10 milliwatts per square meter and an afterglow of more than 2 h.Experimental characterizations coupled with first-principles calculations have revealed that structural defects associated with oxygen introduction-induced anion vacancies in fluoride elpasolite can function as electron traps,which capture and store a large number of electrons triggered by Xray irradiation.Notably,we show that the ultraviolet C afterglow intensity of the yielded phosphor is sufficiently strong for sterilization.Our discovery of this ultraviolet C afterglow opens up new avenues for research on persistent phosphors,and it offers new perspectives on their applications in terms of sterilization,disinfection,drug release,cancer treatment,anti-counterfeiting,and beyond.Yan-Min Yang Zhi-Yong Li Jun-Ying Zhang Yue Lu Shao-Qiang Guo Qing Zhao Xin Wang Zi-Jun Yong Hong Li Ju-Ping Ma Yoshihiro Kuroiwa Chikako Moriyoshi Li-Li Hu Li-Yan Zhang Li-Rong Zheng Hong-Tao Sun 2018Light(Science & Applications)2018,7,1:7
13Syntheses and characterization of anti-thrombotic and anti-oxidative Gastrodin-modified polyurethane for vascular tissue engineering显示文摘Vascular grafts must avoid negative inflammatory responses and thrombogenesis to prohibit fibrotic deposition immediately upon implantation and promote the regeneration of small diameter blood vessels(<6 mm inner diameter).Here,polyurethane(PU)elastomers incorporating anti-coagulative and anti-inflammatory Gastrodin were fabricated.The films had inter-connected pores with porosities equal to or greater than 86%and pore sizes ranging from 250 to 400μm.Incorporation of Gastrodin into PU films resulted in desirable mechanical properties,hydrophilicity,swelling ratios and degradation rates without collapse.The released Gastrodin maintained bioactivity over 21 days as assessed by its anti-oxidative capability.The Gastrodin/PU had better anti-coagulation response(less observable BSA,fibrinogen and platelet adhesion/activation and suppressed clotting in whole blood).Red blood cell compatibility,measured by hemolysis,was greatly improved with 2Gastrodin/PU compared to other Gastrodin/PU groups.Notably,Gastrodin/PU upregulated anti-oxidant factors Nrf2 and HO-1 expression in H2O2 treated HUVECs,correlated with decreasing pro-inflammatory cytokines TNF-αand IL-1β in RAW 264.7 cells.Upon implantation in a subcutaneous pocket,PU was encapsulated by an obvious fibrous capsule,concurrent with a large amount of inflammatory cell infiltration,while Gastrodin/PU induced a thinner fibrous capsule,especially 2Gastrodin/PU.Further,enhanced adhesion and proliferation of HUVECs seeded onto films in vitro demonstrated that 2Gastrodin/PU could help cell recruitment,as evidenced by rapid host cell infiltration and substantial blood vessel formation in vivo.These results indicate that 2Gastrodin/PU has the potential to facilitate blood vessel regeneration,thus providing new insight into the development of clinically effective vascular grafts.Meng Zheng Jiazhi Guo Qing Li Jian Yang Yi Han Hongcai Yang Mali Yu Lianmei Zhong Di Lu Limei Li Lin Sun 2021Bioactive Materials2021,6,2:7
14Simultaneous incorporation of PTH(1-34) and nano-hydroxyapatite into Chitosan/Alginate Hydrogels for efficient bone regeneration显示文摘Tissue regeneration based on the utilization of artificial soft materials is considered a promising treatment for bone-related diseases.Here,we report cranial bone regeneration promoted by hydrogels that contain parathyroid hormone(PTH)peptide PTH(1-34)and nano-hydroxyapatite(nHAP).A combination of the positively charged natural polymer chitosan(CS)and negatively charged sodium alginate led to the formation of hydrogels with porous structures,as shown by scanning electron microscopy.Rheological characterizations revealed that the mechanical properties of the hydrogels were almost maintained upon the addition of nHAP and PTH(1-34).In vitro experiments showed that the hydrogel containing nHAP and PTH(1-34)exhibited strong biocompatibility and facilitated osteogenic differentiation of rat bone marrow mesenchymal stem cells(rBMSCs)via the Notch signaling pathway,as shown by the upregulated expression of osteogenic-related proteins.We found that increasing the content of PTH(1-34)in the hydrogels resulted in enhanced osteogenic differentiation of BMSCs.Implantation of the complex hydrogel into a rat cranial defect model led to efficient bone regeneration compared to the rats treated with the hydrogel alone or with nHAP,indicating the simultaneous therapeutic effect of nHAP and PTH during the treatment process.Both the in vitro and in vivo results demonstrated that simultaneously incorporating nHAP and PTH into hydrogels shows promise for bone regeneration,suggesting a new strategy for tissue engineering and regeneration in the future.Zhiyuan Zou Le Wang Zhifei Zhou Qing Sun Delong Liu Yan Chen Hao Hu Yu Cai Sixiong Lin Zhengran Yu Bizhi Tan Wei Guo Zemin Ling Xuenong Zou 2021Bioactive Materials2021,6,6:7
15The FGOALS climate system model as a modeling tool for supporting climate sciences:An overview显示文摘Climate system models are useful tools for understanding the interactions among the components of the climate system and predicting/projecting future climate change. The development of climate models has been a central focus of the State Key Laboratory of Numerical Modeling for Atmospheric Sciences and Geophysical Fluid Dynamics, Institute of Atmospheric Physics, Chinese Academy of Sciences(LASG/IAP) since the establishment of the laboratory in 1985. In China, many pioneering component models and fully coupled models of the climate system have been developed by LASG/IAP. The fully coupled climate system developed in the recent decade is named FGOALS(Flexible Global Ocean-Atmosphere-Land System Model). In this paper, an application-oriented review of the LASG/IAP FGOALS model is presented. The improved model performances are demonstrated in the context of cloud-radiation processes, Asian monsoon, ENSO phenomena, Atlantic Meridional Overturning Circulation(AMOC) and sea ice. The FGOALS model has contributed to both CMIP5(Coupled Model Intercomparison Project-phase 5) and IPCC(Intergovernmental Panel on Climate Change) AR5(the Fifth Assessment Report). The release of FGOALS data has supported the publication of nearly 500 papers around the world. The results of FGOALS are cited ~106 times in the IPCC WG1(Working Group 1) AR5. In addition to the traditional long-term simulations and projections, near-term decadal climate prediction is a new set of CMIP experiment, progress of LAGS/IAP in the development of nearterm decadal prediction system is reviewed. The FGOALS model has supported many Chinese national-level research projects and contributed to the national climate change assessment report. The crucial role of FGOALS as a modeling tool for supporting climate sciences is highlighted by demonstrating the model's performances in the simulation of the evolution of Earth's climate from the past to the future.TianJun Zhou Bin Wang YongQiang Yu YiMin Liu WeiPeng Zheng LiJuan Li Bo Wu PengFei Lin Zhun Guo WenMin Man Qing Bao AnMin Duan HaiLong Liu XiaoLong Chen Bian He JianDong Li LiWei Zou XiaoCong Wang LiXia Zhang Yong Sun WenXia Zhang 2018Earth and Planetary Physics2018,2,4:6
16Effect of heme oxygenase-1 on renal function in rats with liver cirrhosis显示文摘AIM: To investigate the role of heme oxygenase-1 (HO-1) in pathogenesis of experimental hepatorenal syndrome (HRS). METHODS: Rats were divided into liver cirrhotic group, zinc protoporphyrin IX (ZnPP) treatment group, cobalt protoporphyrin (CoPP) treatment group and sham group. Biliary cirrhosis was established by bile duct ligation in the first three groups. Rats in the ZnPP and CoPP treatment groups received intraperitoneal injection of ZnPP and CoPP, respectively, 24 h before sample collection. Expression of HO-1 mRNA in kidney was detected by reverse-transcription polymerase chain reaction, while protein expression was determined by immunohis-tochemical analysis. Hematoxylin and eosin staining was performed to observe liver cirrhosis and renal structure. Renal artery blood flow, mean arterial pressure and portal vein pressure, 24 h total urinary volume, serum and urine sodium concentrations, and creatinine clearance rate (Ccr) were also measured.RESULTS: The HO-1 mRNA and protein expression levels in kidney, 24 h total urinary volume, renal artery blood flow, serum and urine sodium concentration and Ccr were lower in cirrhotic group than in sham group (P < 0.05). However, they were significantly lower in ZnPP treatment group than in cirrhotic group and significantly higher in CoPP treatment group than in cirrhotic group (P < 0.05). CONCLUSION: Low HO-1 expression level in kidney is an important factor for experimental HRS.Shi-Bin Guo Zhi-Jun Duan Qing Li Xiao-Yu Sun 2011World Journal of Gastroenterology2011,17,3:6
17Epidemiology of urticaria in China:a population-based study显示文摘Background:Urticaria is a common skin disease characterized by episodes of wheals,and it has a negative effect on patients’quality of life.Large-scale population-based epidemiological studies of urticaria are scarce in China.The aim of this survey was to determine the prevalence,clinical forms,and risk factors of urticaria in the Chinese population.Methods:This survey was conducted in 35 cities from 31 provinces,autonomous regions,and municipalities of China.Two to three communities in each city were selected in this investigation.Participants completed questionnaires and received dermatological examinations.We analyzed the prevalence,clinical forms,and risk factors of urticaria.Results:In total,44,875 questionnaires were distributed and 41,041 valid questionnaires were collected(17,563 male and 23,478 female participants).The lifetime prevalence of urticaria was 7.30%,with 8.26%in female and 6.34%in male individuals(P<0.05).The point prevalence of urticaria was 0.75%,with 0.79%in female and 0.71%in male individuals(P<0.05).Concomitant angioedema was found in 6.16%of patients.Adults had a higher prevalence of urticaria than adolescents and children.Living in urban areas,exposure to pollutants,an anxious or depressed psychological status,a personal and family history of allergy,thyroid diseases,and Helicobacter pylori infection were associated with a higher prevalence of urticaria.Smoking was correlated with a reduced risk of urticaria.Conclusion:This study demonstrated that the lifetime prevalence of urticaria was 7.30%and the point prevalence was 0.75%in the Chinese population;women had a higher prevalence of urticaria than men.Various factors were correlated with urticaria.Jiaqing Li Dandan Mao Shuoshuo Liu Ping Liu Jing Tian Chenhong Xue Xiaojing Liu Ruiqun Qi Bingxue Bai Jianjun Nie Siqi Ye Yu Wang Yuye Li Qing Sun Juan Tao Shuping Guo Hong Fang Jianqin Wang Qiri Mu Quanzhong Liu Yan Ding Jianzhong Zhang 2022Chinese Medical Journal2022,,11:6
18Lipoprotein(a) as a Marker for Predicting the Presence and Severity of Coronary Artery Disease in Untreated Chinese Patients Undergoing Coronary Angiography显示文摘Objective Low-density lipoprotein cholesterol(LDL-C) has been well known as the risk factor of coronary artery disease(CAD). However, the role of lipoprotein(a) [Lp(a)] in the development of CAD is of great interest but still controversial. Thus, we aim to explore the effect of Lp(a) on predicting the presence and severity of CAD in Chinese untreated patients, especially in combination with LDL-C. Methods We consecutively recruited 1,980 non-treated patients undergoing coronary angiography, among which 1,162 patients were diagnosed with CAD. Gensini score(GS) was used to assess the severity of CAD. Lp(a) was measured by immunoturbidimetric method. Results Patients with CAD had higher level of LDL-C and Lp(a) compared with non-CAD(P < 0.05). Multivariable logistic regression revealed that Lp(a) > 205 mg/L(highest tertile) predicted 1.437-fold risk for CAD(95% CI: 1.108-1.865, P = 0.006) and 1.480-fold risk for high GS(95% CI: 1.090-2.009, P = 0.012) respectively. Interestingly, concomitant elevated level of Lp(a) and LDL-C conferred the highest risk for both presence [OR = 1.845, 95% CI: 1.339-2.541, P < 0.001] and severity [OR = 1.736, 95% CI: 1.188-2.538, P = 0.004] of CAD. Conclusion Lipoprotein(a) is a useful marker for predicting the presence and severity of CAD, especially combined with LDL-C.SUN Di ZHAO Xi LI Sha ZHANG Yan WU Na Qiong ZHU Cheng Gang GUO Yuan Lin GAO Ying QING Ping LIU Geng DONG Qian LI Jian Jun 2018Biomedical and Environmental Sciences2018,31,4:6
19Methylene blue prevents osteoarthritis progression and relieves pain in rats via upregulation of Nrf2/PRDX1显示文摘Oxidative stress-related cartilage degeneration, synovitis, and joint pain play vital roles in the progress of osteoarthritis (OA). Anti-oxidative stress agents not only prevent structural damage progression but also relieve OA-related pain. In this study, we investigated the therapeutic effect of methylene blue (MB), a classical and important anti-oxidant with strong neural affinity. Experimental OA was established in rats by radial transection of medial collateral ligament and medial meniscus (MCLT + MMT) of the right knee joint. The OA rats received intra-articular injection of MB (1 mg/kg) every week starting one week after surgery. We showed that MB administration exerted significant cartilage protection, synovitis inhibition as well as pain relief in OA rats. In human chondrocytes and fibroblast-like synoviocytes, MB significantly attenuated tert-butyl hydroperoxide (TBHP)-induced inflammatory response and oxidative stress. We demonstrated that these effects of MB resulted from dual targets of important antioxidant enzymes, Nrf2 and PRDX1, which also mutually reinforcing and participated in an interaction. Furthermore, we found that calcitonin gene-related peptide (CGRP), a neural inflammatory mediator, was accumulated around the vessel in synovium and subchondral bone in OA rats and in TBHP-treated primary cortical neurons;MB administration significantly inhibited CGRP expression through upregulation of Nrf2 and PRDX1. Taken together, these results suggest that MB ameliorates oxidative stress via Nrf2/PRDX1 regulation to prevent progression and relieve pain of OA.Jia-wei Li Rong-liang Wang Jia Xu Kuo-yang Sun Hui-ming Jiang Zi-ying Sun Zhong-yang Lv Xing-quan Xu Rui Wu Hu Guo Qing Jiang Dong-quan Shi 2022Acta Pharmacologica Sinica2022,43,2:5
