| 1 | Transplantation of collagen scaffold with autologous bone marrow mononuclear cells promotes functional endometrium reconstruction via downregulating ΔNp63 expression in Asherman's syndrome显示文摘Asherman's syndrome(AS) is a common disease that presents endometrial regeneration disorder. However, little is known about its molecular features of this aregenerative endometrium in AS and how to reconstruct the functioning endometrium for the patients with AS. Here, we report that ΔNp63 is significantly upregulated in residual epithelial cells of the impaired endometrium in AS; the upregulated-ΔNp63 induces endometrial quiescence and alteration of stemness. Importantly, we demonstrate that engrafting high density of autologous bone marrow mononuclear cells(BMNCs) loaded in collagen scaffold onto the uterine lining of patients with AS downregulates ΔNp63 expression, reverses ΔNp63-induced pathological changes, normalizes the stemness alterations and restores endometrial regeneration. Finally, five patients achieved successful pregnancies and live births. Therefore, we conclude that ΔNp63 is a crucial therapeutic target for AS. This novel treatment significantly improves the outcome for the patients with severe AS. | Guangfeng Zhao Yun Cao Xianghong Zhu Xiaoqiu Tang Lijun Ding Haixiang Sun Juan Li Xinan Li Chenyan Dai Tong Ru Hui Zhu Jingjie Lu Caimei Lin Jingmei Wang Guijun Yan Huiyan Wang Lei Wang Yimin Dai Bin Wang Ruotian Li Jianwu Dai Yan Zhou Yali Hu | 2017 | Science China(Life Sciences)2017,60,4: | 39 |
| 2 | Roles of dietary supplementation with arginine or N-carbamylglutamate in modulating the inflammation, antioxidant property, and m RNA expression of antioxidant-relative signaling molecules in the spleen of rats under oxidative stress显示文摘This study evaluated the effects of arginine(Arg) or N-carbamylglutamate(NCG) on inflammation, antioxidant property, and antioxidant-related gene expression in rat spleen under oxidative stress. A total of 52 rats were randomly distributed into 4 treatment groups with 13 replicates per group. Rats were fed a basal diet(BD) or BD supplemented with Arg or NCG for 30 days. On day 28, half of the BD-fed rats were intraperitoneally injected with sterile saline(control group), and the other half with 12 mg/kg body weight of diquat(DT; DT group). The other 2 diet groups were intraperitoneally injected with 12 mg/kg body weight of DT with either Arg(1%)(DT t Arg) or NCG(0.1%)(DT t NCG). Rat spleen samples were collected for analysis at 48 h after DT injection. Results showed that DT damaged the antioxidant defense in rats compared with the control group(P < 0.05). Compared with the DT group, the DT t Arg and DT t NCG groups manifested improved anti-hydroxyl radical, catalase, and total superoxide dismutase(T-SOD) activities, increased glutathione content(P < 0.05), and decreased malondialdehyde content(P < 0.05).Moreover, compared with the DT group, the DT t Arg and DT t NCG groups enhanced mRNA expression of superoxide dismutase(SOD), glutathione peroxidase 1(GPx1), glutathione reductase(GR), nuclear factor erythroid 2-related factor 2(Nrf2), Kelch-like ECH-associated protein 1(Keap-1), and mammalian target of rapamycin(m TOR)(P < 0.05). Both NCG and Arg significantly increased anti-inflammatory cytokine mRNA level but suppressed the pro-inflammatory cytokine mRNA expression under oxidative stress(P < 0.05). In summary, NCG and Arg effectively alleviated oxidative stress, improved the antioxidant capacity and regulated the antioxidant-related signaling molecular expression in rat spleen. N-carbamylglutamate and Arg reduced the inflammation in the spleen by mediating the gene expression of anti-inflammatory and pro-inflammatory cytokines and transforming growth factor-β(TGF-β). | Weiwei Mo Xianjian Wu Gang Jia Hua Zhao Xiaoling Chen Jiayong Tang Caimei Wu Jingyi Cai Gang Tian Jing Wang Gangmang Liu | 2018 | Animal Nutrition2018,,3: | 9 |
| 3 | New insights into the role of spermine in enhancing the antioxidant capacity of rat spleen and liver under oxidative stress显示文摘Oxidative stress can damage cellular antioxidant defense and reduce livestock production efficiency.Spermine is a ubiquitous cellular component that plays important roles in stabilizing nucleic acids,modulating cell growth and differentiation, and regulating ion channel activities. Spermine has the potential to alleviate the effects of oxidative stress. However, to date no information is available about the effect of spermine administration on antioxidant property of the liver and spleen in any mammalian in vivo system. This study aims to investigate the protective effect of spermine on rat liver and spleen under oxidative stress. Rats received intragastric administration of either 0.4 μmol/g body weight of spermine or saline once a day for 3 days. The rats in each treatment were then injected with either diquat or sterile saline at 12 mg/kg body weight. Liver and spleen samples were collected 48 h after the last spermine ingestion.Results showed that regardless of diquat treatment, spermine administration significantly reduced the malondialdehyde(MDA) content by 23.78% in the liver and by 5.75% in the spleen, respectively(P < 0.05).Spermine administration also enhanced the catalase(CAT) activity, anti-hydroxyl radical(AHR) capacity and glutathione(GSH) content by 38.68%, 15.53% and 1.32% in the spleen, respectively(P< 0.05). There were interactions between spermine administration and diquat injection about anti-superoxide anion(ASA),AHR capacity, CAT activity, GSH content, and total antioxidant capacity(T-AOC) in the liver and about ASA capacity and T-AOC in the spleen of weaned rats(P < 0.05). Compared with the control group, spermine administration significantly increased the AHR capacity, CAT activity, GSH content, and T-AOC by 40.23%,31.15%, 30.25%, 35.37% in the liver, respectively(P < 0.05) and increased the T-AOC by 8% in the spleen of weaned rats(P < 0.05). Compared with the diquat group, spermine + diquat group significantly increased ASA capacity by 15.63% in the liver and by 73.41% in the spleen of weaned rats, respectively(P < 0.05).Results demonstrate that spermine administration can increase the antioxidant capacity in the liver and spleen and can enhance the antioxidant status in the spleen and liver under oxidative stress. | Xianjian Wu Wei Cao Gang Jia Hua Zhao Xiaoling Chen Caimei Wu Jiayong Tang Jing Wang Guangmang Liu | 2017 | Animal Nutrition2017,,1: | 4 |
| 4 | A system for automated monitoring of embankment deformation along the Qinghai-Tibet Railway in permafrost regions显示文摘At present, the monitoring of embankment deformation in permafrost regions along the Qinghai-Tibet Railway is mainly done manually. However, the harsh climate on the plateau affects the results greatly by lowering the observation frequency, so the manual monitoring can barely meet the observational demand. This research develops a system of automated monitoring of embankment deformation, and aims to address the problems caused by the plateau climate and the permafrost conditions in the region. The equipment consists of a monitoring module, a data collection module, a transmission module, and a data processing module. The field experiments during this program indicate that(1) the combined automated monitoring device overcame the problems associated with the complicated and tough plateau environment by means of wireless transmission and automatic analysis of the embankment settlement data;(2) the calibration of the combined settlement gauge at-20 °C was highly accurate, with an error rate always <0.5%;(3) the gauge calibration at high-temperature conditions was also highly accurate, with an error rate <0.5% even though the surface of the instrument reached more than 50 °C; and(4) compared with the data manually taken, the data automatically acquired during field monitoring experiments demonstrated that the combined settlement gauge and the automated monitoring system could meet the requirements of the monitoring mission in permafrost regions along the Qinghai-Tibet Railway. | YongPeng Yang YaoHui Qu HanCheng Cai JiaCheng CaiMei Tang | 2015 | Research in Cold and Arid Regions2015,7,5: | 2 |
| 5 | An emerging role of arecoline on growth performance,intestinal digestion and absorption capacities and intestinal structural integrity of adult grass carp(Ctenopharyngodon idella)显示文摘Arecoline is an alkaloid with important pharmacological effects in the plant areca nut,which has been demonstrated to be an agonist of muscarinic receptors(M receptor).This study explored the influences of dietary arecoline on growth performance,intestinal digestion and absorption abilities,antioxidant capacity,and the apical junction complex(AJC)of adult grass carp(Ctenopharyngodon idella).Adult grass carp(608to 1512 g)were fed at 6 graded levels of dietary arecoline(0,0.5,1.0,1.5,2.0,and 2.5 mg/kg diet)for 9weeks.The results suggested that appropriate dietary supplementation of arecoline(1.0 mg/kg)increased growth parameters and intestinal growth in adult grass carp(P<0.05),enhanced digestion and absorption capacities(P<0.05),up-regulated muscarinic receptor 3(M3)mRNA level(P<0.05),increased the content of neuropeptide fish substance P(P<0.05),improved antioxidant capacity by activating the Keap1a/Nrf2signaling pathway(P<0.05),reduced intestinal mucosal permeability(P<0.05),and increased m RNA levels of tight junction(TJ)and adherent junction AJ-related proteins in fish by inhibiting the RhoA/ROCK signaling pathway(RhoA/ROCK/MLCK/NMII)(P<0.05).In addition,the appropriate arecoline supplementation for adult grass carp was determined to be 1.20,1.21,1.07,and 1.19 mg/kg based on percentage weight gain,lipase activity,serum diamine oxidase,and protein carbonyl,respectively.Overall,to the best of our knowledge,we investigated for the first time the effects and possible mechanisms of dietary arecoline on intestinal digestive and absorptive capacities and structural integrity in fish and evaluated the appropriate level of supplementation. | Na Yao Lin Feng Weidan Jiang Pei Wu Hongmei Ren Hequn Shi Ling Tang Shuwei Li Caimei Wu Hua Li Yang Liu Xiaoqiu Zhou | 2023 | Animal Nutrition2023,,4: | 0 |
