1Comparative Analysis on Chemical Components and Sensory Quality of Aging Flue-Cured Tobacco from Four Main Tobacco Areas of China显示文摘Complicated changes are happening during the aging process of flue-cured tobacco (FCT) and understanding of the changing components is of great significance in improving the quality,shortening aging time,and enhancing production and economic efficiency in tobacco industry.The aging samples of FCT from four main producing areas of China,i.e.,Yunnan,Sichuan,Hubei,and Dongbei,were used to study the changing rule of the components such as alkali,acid,and carbohydrate as well as the aroma and their relationship with sensory quality;and based on the correlation among the components and the sensory quality index,multivariable models were established to predict the aging quality.The results showed that the sensory quality of FCT increased steadily during the aging time,and at the same time,the acidic components (total organic acids,volatile acids) increased gradually,while the alkaline substances (nicotine,volatile alkali),carbohydrate (total sugars,reducing sugar) and pH values showed a downward trend.Correlation analysis found that the sensory quality and pH values were negatively correlated (P<0.05),while the sensory quality with total organic acids and aroma were positively correlated.The optimal model for predicting the quality of FCT was y=56.75-0.63x12+50.09x2-13.27x22,(y:sensory quality;x1:pH;x2:total organic acids).The average predicating error was 1.04% with maximum predicating error of 2.89% and the accuracy rate of above 97%.SUN Jing-guo HE Jie-wang WU Feng-guang TU Shu-xing YAN Tie-jun SI Hui XIE Hao 2011Agricultural Sciences in China2011,10,8:20
2Prognosis-related classifi cation and dynamic monitoring of immune status in patients with sepsis:A prospective observational study显示文摘BACKGROUND:The dynamic monitoring of immune status is crucial to the precise and individualized treatment of sepsis.In this study,we aim to introduce a model to describe and monitor the immune status of sepsis and to explore its prognostic value.METHODS:A prospective observational study was carried out in Zhongshan Hospital,Fudan University,enrolling septic patients admitted between July 2016 and December 2018.Blood samples were collected at days 1 and 3.Serum cytokine levels(e.g.,tumor necrosis factor-α[TNF-α],interleukin-10[IL-10])and CD14+monocyte human leukocyte antigen-D-related(HLA-DR)expression were measured to serve as immune markers.Classifi cation of each immune status,namely systemic inflammatory response syndrome(SIRS),compensatory anti-inflammatory response syndrome(CARS),and mixed antagonistic response syndrome(MARS),was defined based on levels of immune markers.Changes of immune status were classifi ed into four groups which were stabilization(SB),deterioration(DT),remission(RM),and non-remission(NR).RESULTS:A total of 174 septic patients were enrolled including 50 non-survivors.Multivariate analysis discovered that IL-10 and HLA-DR expression levels at day 3 were independent prognostic factors.Patients with MARS had the highest mortality rate.Immune status of 46.1%patients changed from day 1 to day 3.Among four groups of immune status changes,DT had the highest mortality rate,followed by NR,RM,and SB with mortality rates of 64.7%,42.9%,and 11.2%,respectively.CONCLUSIONS:Severe immune disorder defi ned as MARS or deterioration of immune status defi ned as DT lead to the worst outcomes.The preliminary model of the classifi cation and dynamic monitoring of immune status based on immune markers has prognostic values and is worthy of further investigation.Jun Yin Yao Chen Jun-ling Huang Lei Yan Zhong-shu Kuang Ming-ming Xue Si Sun Hao Xiang Yan-yan Hu Zhi-min Dong Chao-yang Tong Chun-xue Bai Zhen-ju Song 2021World Journal of Emergency Medicine2021,12,3:16
3Supramolecular complex formation of β-cyclodextrin polymer with substituted salicylic acid or 3-hydroxy-2-naphthoic acid and their electrorheological behaviors显示文摘According to the chemical design, electrorheological properties of supramolecular complex from b-cyclodextrin polymer (b -CDP) were discussed. Six supramolecular complexes of -cyclodextrin polymer with substituted salicylic acid and 3-hydroxy-2-naphthoic acid were syn-thesized by the solid-phase self-assembly method, and their component and structure were characterized by NMR, FT-IR, UV-vis and the fluorescence analysis. Then the electrorheological properties of their suspensions in silicone oil were investigated under DC electric fields. It was found that the yield stresses of these supramolecular complex ER fluids were 7.3—9.8 kPa at 4 kV/mm in DC electric field, which were enhanced by 34%—72% compared with that of pure b-CDP. Among them, that of b-CDP/3-hydroxy-2-naphthoic acid ER fluid was the highest. It was also found that the ER effect of supramolecular complexes can be controlled by changing dif-ferent guests. When the substituted group is at phenyl ring, ER behavior can be slightly adjusted by the different substituted groups, their number as well as their position at phenyl ring. This can be proved by the measurement of dielectric properties.GAO Ziwei1,2, ZHAO Xiaopeng1, SUN Ping2 & SI Gang2 1.

4Low-dose quercetin positively regulates mouse healthspan显示文摘Dear Editor,Aging is the leading risk factor for many chronic diseases,accounting for almost 60%of all deaths worldwide.How to achieve healthy aging,alleviate aging-related diseases,and extend healthspan has become a main topic of biomedical research(He et al.,2019).Geroprotective compounds,such as metformin and rapamycin,have been shown to improve both healthspan and lifespan in mice(Martin-Montalvo et al.,2013;Bitto et al.,2016),whereas nicotinamide partially improves healthspan in mice(Mitchell et al.,2018).Lingling Geng Zunpeng Liu Si Wang Shuhui Sun Shuai Ma Xiaoqian Liu Piu Chan Liang Sun Moshi Song Weiqi Zhang Guang-Hui Liu Jing Qu 2019Protein & Cell2019,10,10:12
5Identification and Fine Mapping of a Gene Related to Pale Green Leaf Phenotype near the Centromere Region in Rice(Oryza sativa)显示文摘A thermo-insensitive pale green leaf mutant (pgl2) was isolated from T-DNA inserted transgenic lines of rice (Oryza sativa L. subsp. japonica cv. Nipponbare). Genetic analysis indicated that the phenotype was caused by a recessive mutation in a single nuclear-encoded gene. To map the PGL2 gene, an F2 population was constructed by crossing the mutant with Longtefu (Oryza sativa L. subsp. indica). The PGL2 locus was roughly linked to SSR marker RM331 on chromosome 8. To finely map the gene, 14 new InDel markers were developed around the marker, and PGL2 was further mapped to a 2.37 Mb centromeric region. Analysis on chlorophyll contents of leaves showed that there was no obvious difference between the mutant and the wild type in total chlorophyll (Chl) content, while the ratio of Chl a / Chl b in the mutant was only about 1, which was distinctly lower than that in the wild type, suggesting that the PGL2 gene was related to the conversion between Chl a and Chl b. Moreover, the method of primer design around the centromeric region was discussed, which would provide insight into fine mapping of the functional genes in plant centromeres.ZHU Li LiuWenzhen WU Chao LUAN Wei jiang Fu Ya ping Hu Guo cheng SI Hua min SUN Zong xiu 2007Rice science2007,14,3:11

7Anlotinib has good efficacy and low toxicity: a phase Ⅱ study of anlotinib in pre-treated HER-2 negative metastatic breast cancer显示文摘Objective:Anlotinib is a novel tyrosine kinase inhibitor blocking angiogenesis.This study was performed to assess the efficacy and safety of anlotinib in patients with metastatic breast cancer.Methods:Patients with HER2-negative breast cancer,who were pre-treated with anthracycline or taxanes in a neoadjuvant,adjuvant,or metastatic setting,and had treatment failure after at least one prior chemotherapy regimen in the metastatic setting were enrolled.Anlotinib was administered at 12 mg daily for 14 days in a 21-day cycle until disease progression or unacceptable toxicity occurred.Simultaneously,5–10 m L of venous blood was collected to perform circulating tumor DNA(ct DNA)testing every 2 treatment cycles.The primary endpoint was the objective response rate(ORR).Secondary endpoints included the disease control rate(DCR),progression-free survival(PFS),overall survival,safety,and biomarkers.Results:Twenty-six eligible patients were enrolled,with a median age of 56(30–75)years.The median follow-up time was 10.5 months.The ORR was 15.4%,the DCR was 80.8%,and the median PFS was 5.22 months(95%confidence interval 2.86–6.24).Fourteen(53.8%)patients survived for more than 10 months.The changes in the detectable ct DNA variant allele frequency were consistent with the tumor response.The most common treatment-related adverse events were hypertension(57.7%),thyroidstimulating hormone elevation(34.6%),and hand-foot syndrome(23.1%).Conclusion:Anlotinib showed objective efficacy with tolerable toxicity in heavily pre-treated,metastatic HER2-negative breast cancer.The dynamic changes in the ct DNA variant allele fraction may be predictive of the tumor response.Nanlin Hu Yiran Si Jian Yue Tingting Sun Xue Wang Zhuqing Jia Songlin Gao Qiao Li Yang Shao Jiayu Wang Yang Luo Fei Ma Binghe Xu Peng Yuan 2021Cancer Biology & Medicine2021,18,3:11
8Single-cell transcriptomic atlas of primate cardiopulmonary aging显示文摘Aging is a major risk factor for many diseases,especially in highly prevalent cardiopulmonary comorbidities and infectious diseases including Coronavirus Disease 2019(COVID-19).Resolving cellular and molecular mechanisms associated with aging in higher mammals is therefore urgently needed.Here,we created young and old non-human primate single-nucleus/cell transcriptomic atlases of lung,heart and artery,the top tissues targeted by SARS-CoV-2.Analysis of cell type-specific aging-associated transcriptional changes revealed increased systemic inflammation and compromised virus defense as a hallmark of cardiopulmonary aging.With age,expression of the SARS-CoV-2 receptor angiotensin-converting enzyme 2(ACE2)was increased in the pulmonary alveolar epithelial barrier,cardiomyocytes,and vascular endothelial cells.We found that interleukin 7(IL7)accumulated in aged cardiopulmonary tissues and induced ACE2 expression in human vascular endothelial cells in an NF-κB-dependent manner.Furthermore,treatment with vitamin C blocked IL7-induced ACE2 expression.Altogether,our findings depict the first transcriptomic atlas of the aged primate cardiopulmonary system and provide vital insights into age-linked susceptibility to SARS-CoV-2,suggesting that geroprotective strategies may reduce COVID-19 severity in the elderly.Shuai Ma Shuhui Sun Jiaming Li Yanling Fan Jing Qu Liang Sun Si Wang Yiyuan Zhang Shanshan Yang Zunpeng Liu Zeming Wu Sheng Zhang Qiaoran Wang Aihua Zheng Shuguang Duo Yang Yu Juan Carlos Izpisua Belmonte Piu Chan Qi Zhou Moshi Song Weiqi Zhang Guang-Hui Liu 2021Cell Research2021,31,4:10

11Extraction, identification, and antioxidant property evaluation of limonin from pummelo seeds显示文摘Limonin, the main bioactive phytochemical constituent of limonoids with multi-functions, is enriched in citrus fruits and often found at a high concentration in citrus seeds. The present study was attempted to introduce a new and efficient extraction method to isolate limonoids from pummelo seeds, and to evaluate the antioxidant property of the main constituent limonin in Hep G2 cells. Three key single factors were identified for the extraction of limonoids from pummelo seeds using the Box-Behnken experiment design of response surface methodology(RSM), and the optimized extraction parameters were treatment with 89.68 m L of anhydrous acetone for 4.62 h at 78.94C, while the yield of limonoids was 11.52 mg/g. The structure of isolated main constituent of the limonoids was further identified as limonin by Fourier transform infrared(FT-IR) spectrometer and nuclear magnetic resonance(NMR)spectrum. Moreover, the molecular data in Hep G2 cells revealed that limonin exerted its anti-oxidant property mainly by the activation of nuclear factor(erythroid-2)-like 2(Nrf2)/kelch-like ECHassociated protein 1(Keap1)-antioxidant response element(ARE) pathway in the form of transcriptional regulation of Nrf2 m RNA and posttranscriptional regulation of Nrf2/Keap1 system. These results demonstrate that pummelo seeds are an ideal source of limonoids, and limonin is proved to exert its anti-oxidant property by the activation of Nrf2/Keap1 pathway.Si Qin Chenghao Lv Qingshan Wang Zhibing Zheng Xi Sun Minyi Tang Fangming Deng 2018Animal Nutrition2018,,3:10
12Improving anode performances of lithium-ion capacitors employing carbon-Si composites显示文摘The lithium-ion capacitor is a promising energy storage system with a higher energy density than traditional supercapacitors.However,its cycling and rate performances,which depend on the electrochemical properties of the anode,are still required to be improved.In this work,soft carbon anodes reinforced using carbon-Si composites of various compositions were fabricated to investigate their beneficial influences on the performance of lithium-ion capacitors.The results showed that the specific capacities of the anodes increased significantly by 16.6 mAh g^(-1) with 1.0 wt% carbon-Si composite,while the initial discharge efficiency barely changed.The specific capacity of the anode with a 10.0 wt% carbon-Si composite reached 513.1 mAh g^(-1),and the initial discharge efficiency was 83.79%.Furthermore,the anodes with 7.5 wt% or lower amounts of carbon-Si composite demonstrated reduced charge transfer resistances,which caused an improvement in the rate performance of the lithium-ion capacitors.Moreover,the use of the optimized amount(7.5 wt%) of carbon-Si composite in the anode could significantly improve the cycling performance of the lithium-ion capacitor by compensating the consumption of active lithium.The capacity retention of the lithium-ion capacitor reached 95.14% at 20 C after 10,000 cycles,while the anode potential remained below 0.412 V,which is much lower than that of a soft carbon anode.Ya-Bin An Si Chen Min-Min Zou Lin-Bin Geng Xian-Zhong Sun Xiong Zhang Kai Wang Yan-Wei Ma 2019Rare Metals2019,38,12:10
13Transarterial embolization ablation of hepatocellular carcinoma with a lipiodol-ethanol mixture显示文摘AIM: To determine the safety and effectiveness of transarterial embolization ablation (TEA) of hepatocellular carcinoma (HCC) with a lipiodol-ethanol mixture. METHODS: Between January 1 and December 31, 2009, 15 patients with HCC (13 men/two women, aged 38-75 years) accepted TEA treatment and were enrolled in this study, including five newly diagnosed patients and 10 with refractory disease. Two months after TEA, angiography and contrast computed tomography (CT) were performed, and responses were assessed using a modified version of Response Evaluation Criteria in Solid Tumors (RECIST version 1.1). The follow-up period was to June 30, 2010. RESULTS: Every new case was treated once. Angiography was performed immediately after TEA, and showed that the tumor-feeding vessels were completely embolized and that lipiodol was densely deposited inside tumors. Two months after treatment, contrast CT showed no enhanced lesions. Alpha fetoprotein levels returned to normal in four patients and markedly decreased in another. mean ± SD survival after treatment was 10.8 ± 4.5 mo. All five patients survived during the follow-up period. Ten patients with refractory disease were treated a total of 14 times. Angiography immediately after TEA showed that blood flow to the tumors was obviously decreased in all cases, and contrast CT showed obvious depositions of lipiodol. Two months after treatment, the tumors had shrunk (6/10) or were stable (3/10). One had progressed after 2 mo and died of tumor rupture 3 mo after TEA. mean ± SD survival after treatment was 8.6 ± 4.3 mo; two patients survived during the follow-up period. Adverse effects included reversible hepatic decompensation, upper abdominal pain, and fever. CONCLUSION: TEA is an effective therapy for patients with HCC and might be more effective than transcather arterial chemoembolization for treating refractory disease.Yang-Kui Gu, Rong-Guang Luo, Jin-Hua Huang, Qi-Jiao Si Tu, Xiao-Xia Li, Fei Gao,State Key Laboratory of Oncology in Southern China,Department of Medical Imaging and Interventional Radiology,Cancer Center,Sun Yat-sen University,Guangzhou510060,Guangdong Province,China Department of Medical Imaging and Interventional Radiology, the First Affiliated Hospital of Nan-Chang University, 17 Yongwaizheng Street, Nanchang 330006, Jiangxi Province, China 2010World Journal of Gastroenterology2010,16,45:9
14Weekly albumin-bound paclitaxel/cisplatin versus gemcitabine/cisplatin as first-line therapy for patients with advanced non-small-cell lung cancer:A phase II open-label clinical study显示文摘Objective: The aim of this trial was to compare both the efficacy and the safety of a weekly nanoparticle albumin-bound paclitaxel(nab-paclitaxel) plus cisplatin vs. gemcitabine plus cisplatin in patients with advanced non-small-cell lung cancer(NSCLC).Methods: A total of 84 participants received either 100 mg/m^2 nab-paclitaxel each week on d 1, 8 and 15 of a 28 day cycle, as well as cisplatin 75 mg/m^2 on d 1 every three weeks(nab-TP arm); or gemcitabine 1,000 mg/m^2 on d 1 and 8, plus cisplatin 75 mg/m^2 on d 1 every three weeks(GP arm). The primary end point was progression-free survival(PFS). The secondary end points were overall response rate(ORR) and overall survival(OS).Results: According to our analysis, the median PFS was 4.8 months for the nab-TP arm vs. 5.2 months for the GP arm(P=0.55). Analysis showed the median OS was 14.6 months for participants who were in the nab-TP arm vs. 15.1 months for those in the GP arm(P=0.94). Besides, nab-TP showed OS advantages over GP in patients harboring epidermal growth factor receptor(EGFR) mutation(26.7 vs. 15.3 months, P=0.046) and patients with a performance status of 0(23.5 vs. 14.7 months, P=0.020). It was found that incidences of drug-related grade 3 or 4 toxicities were comparable between the two treatment arms.Conclusions: Therefore, it can be seen that weekly nab-TP treatment has a similar efficacy and tolerability to GP treatment for patients who are undergoing their first-line treatment for NSCLC. It could be that survival differences among platinum doublets in the context of both EGFR mutation and performance status have the potential to be the basis for our further clinical trials.Shanshan Qin Hui Yu Xianghua Wu Zhiguo Luo Huijie Wang Si Sun Mingzhu Huang Jia Jin Zhonghua Tao Jie Qiao Yu Feng Jialei Wang Jianhua Chang 2019Chinese Journal of Cancer Research2019,31,2:9
15Prognostic values of the integrated model incorporating the volume of metastatic regional cervical lymph node and pretreatment serum Epstein-Barr virus DNA copy number in predicting distant metastasis in patients with N1 nasopharyngeal carcinoma显示文摘Background: According to the 7 th edition of the American Joint Committee on Cancer(AJCC) staging system, over50% of patients with nasopharyngeal carcinoma(NPC) have N1 disease at initial diagnosis. However, patients with N1 NPC are relatively under-researched, and the metastasis risk of this group is not well-stratified. This study aimed to evaluate the prognostic values of gross tumor volume of metastatic regional lymph node(GTVnd) and pretreatment serum copy number of Epstein-Barr virus(EBV) DNA in predicting distant metastasis of patients with N1 NPC, and to develop an integrated prognostic model that incorporates GTVnd and EBV DNA copy number for this group of patients.Methods: The medical records of 787 newly diagnosed patients with nonmetastatic, histologically proven N1 NPC who were treated at Sun Yat-sen University Cancer Center between November 2009 and February 2012 were analyzed. Computed tomography-derived GTVnd was measured using the summation-of-area technique. Blood samples were collected before treatment to quantify plasma EBV DNA. The receiver operating characteristic(ROC) curve analysis was used to evaluate the cut-off point for GTVnd, and the area under the ROC curve was used to assess the predicted validity of GTVnd. The survival rates were assessed by Kaplan-Meier analysis, and the survival curves were compared using a log-rank test. Multivariate analysis was conducted using the Cox proportional hazard regression model.Results: The 5-year distant metastasis-free survival(DMFS) rates for patients with GTVnd > 18.9 vs.≤ 18.9 mL were82.2% vs. 93.2%(P < 0.001), and for patients with EBV DNA copy number > 4000 vs. < 4000 copies/mL were 83.5% vs.93.9%(P < 0.001). After adjusting for GTVnd, EBV DNA copy number, and T category in the Cox regression model, both GTVnd > 18.9 mL and EBV DNA copy number > 4000 copies/mL were significantly associated with poor prognosis(both P < 0.05). According to combination of GTVnd and EBV DNA copy number, all patients were divided into low-,moderate-, and high-risk groups, with the 5-year DMFS rates of 96.1,87.4, and 73.8%, respectively(P < 0.001). Multivariate analysis confirmed the prognostic value of this model for distant metastatic risk stratification(hazard ratio [HR],4.17; 95% confidence interval [CI] 2.34-7.59; P < 0.001).Conclusions: GTVnd and serum EBV DNA copy number are independent prognostic factors for predicting distant metastasis in NPC patients with N1 disease. The prognostic model incorporating GTVnd and EBV DNA copy number may improve metastatic risk stratification for this group of patients.Ji‑Jin Yao Guan‑Qun Zhou Ya‑Qin Wang Si‑Yang Wang Wang‑Jian Zhang Ya‑Nan Jin Fan Zhang Li Li Li‑Zhi Liu Zhi‑Bin Cheng Jun Ma Zhen‑Yu Qi 2017Chinese Journal of Cancer2017,36,12:9
16Endothelial Nitric Oxide Synthase Gene Polymorphisms Associated with Susceptibility to High Altitude Pulmonary Edema in Chinese Railway Construction Workers at Qinghai-Tibet over 4500 Meters above Sea Level显示文摘Objective To examine whether the polymorphisms of endothelial nitric oxide synthase (eNOS) gene are associated with the susceptibility to high altitude pulmonary edema (HAPE) in Chinese railway construction workers at Qinghai-Tibet where the altitude is over 4 500 m above sea level. Methods A case-control study was conducted including 149 HAPE patients in the construction workers and 160 healthy controls randomly recruited from their co-workers, matching the patients in ethnicity, age, sex, lifestyle, and working conditions. Three polymorphisms of eNOS gene, T-786C in promoter, 894G/T in exon 7, and 27bp variable number tandem repeat (VNTR) in intron 4, were genotyped using polymerase chain reaction (PCR) and confirmed with DNA sequencing. Results The frequencies of 894T allele and heterozygous G/T of the 894G/T variant were significantly higher in HAPE patients group than in the control group (P=0.0028 and P=0.0047, respectively). However, the frequencies of the T-786C in promoter and the 27bp VNTR in intron 4 were not significantly different between the two groups. Haplotypic analysis revealed that the frequencies of two haplotypes (H3,T-T-b, b indicates 5 repeats of 27 bp VNTR; H6, C-G-a, a indicates 4 repeats of 27 bp VNTR) were significantly higher in HAPE patients (both P<0.0001). On the contrary, the frequencies of H1 (T-G-b) and H2 (T-G-a) were lower in HAPE patients than in healthy controls (both P<0.001). Conclusions Two haplotypes (T-T-b and C-G-a) may be strongly associated with susceptibility to HAPE. Compared with the individual alleles of eNOS gene, the interaction of multiple genetic markers within a haplotype may be a major determinant for the susceptibility to HAPE.Yu-jing Sun Ming-wu Fang Wen-quan Niu Guang-ping Li Jing-liang Liu Shou-quan Ding Ying Xu Guo-shu Yu Jian-qun Dong Yun-jun Pan Guang-xue Yu Hui-cheng Sun Zhong-hou Jia Jun Liu Xiao-ming Wang Qin Si Qi-xia Wu Wen-yu Zhou Tong-chun Zhu Chang-chun Qiu 2010Chinese Medical Sciences Journal2010,25,4:9

19基于体波有限频层析成像的青藏高原南部和中部下方印度大陆岩石层俯冲和撕裂的三维图像显示文摘使用TIBET-31N无源地震台阵以及以前临时地震台阵记录到的远震体波数据进行了有限频层析成像反演,对青藏高原南部及中部的三维速度结构成像。在喜马拉雅和拉萨地块下方存在向北倾角40°的高速体。我们把这些高速异常区域解释为俯冲的印度大陆岩石层(ICL)。印度大陆岩石层似乎在青藏高原中部比东部向北延伸更多——沿85°E在31°N到达350km深处,而沿91°E则是在30°N到达350km深度。P波和S波低速异常区在当惹雍错裂谷、亚东—谷露裂谷和错那裂谷下方从下地壳延伸至≥180km深度,这表明青藏高原南部的裂谷可能包含了整个岩石层的变形。当惹雍错裂谷下方的异常区向下延伸到约180km,而亚东—谷露裂谷西部和错那裂谷东部的异常延伸到了超过300km的深度。亚东—谷露裂谷西部的低速区上地幔延伸至最北,并且似乎与青藏高原中部下方广阔的上地幔低速区相连。于是,北向俯冲的印度板块沿着南北走向的裂缝撕裂。这些裂缝允许或者导致的软流层上涌同青藏高原北部上地幔相类似。Xiaofeng Liang Yun Chen Xiaobo Tian Yongshun John Chen James Ni Andrea Gallegos Simon L.Klemperer Minling Wang Tao Xu Changqing Sun Shaokun Si Haiqiang Lan Jiwen Teng 左思成 2016世界地震译丛2016,47,6:8
20Chrysophanol protects against doxorubicin-induced cardiotoxicity by suppressing cellular PARylation显示文摘The clinical application of doxorubicin(DOX) in cancer chemotherapy is limited by its lifethreatening cardiotoxic effects. Chrysophanol(CHR), an anthraquinone compound isolated from the rhizome of Rheum palmatum L., is considered to play a broad role in a variety of biological processes.However, the effects of CHR’s cardioprotection in DOX-induced cardiomyopathy is poorly understood. In this study, we found that the cardiac apoptosis, mitochondrial injury and cellular PARylation levels were significantly increased in H9 C2 cells treated by Dox, while these effects were suppressed by CHR. Similar results were observed when PARP1 activity was suppressed by its inhibitors 3-aminobenzamide(3 AB)and ABT888. Ectopic expression of PARP1 effectively blocked this CHR’s cardioprotection against DOX-induced cardiomyocyte injury in H9 C2 cells. Furthermore, pre-administration with both CHR and 3 AB relieved DOX-induced cardiac apoptosis, mitochondrial impairment and heart dysfunction in Sprague–Dawley rat model. These results revealed that CHR protects against DOX-induced cardiotoxicity by suppressing cellular PARylation and provided critical evidence that PARylation may be a novel target for DOX-induced cardiomyopathy.Jing Lu Jingyan Li Yuehuai Hu Zhen Guo Duanping Sun Panxia Wang Kaiteng Guo Dayue Darrel Duan Si Gao Jianmin Jiang Junjian Wang Peiqing Liu 2019Acta Pharmaceutica Sinica B2019,9,4:8
