2Clinical and procedural predictors of no-ref low in patients with acute myocardial infarction after primary percutaneous coronary intervention显示文摘BACKGROUND: The treatment of acute myocardial infarction(AMI) is thought to restore antegrade blood flow in the infarct-related artery(IRA) and minimize ischemic damage to the myocardium as soon as possible. The present study aimed to identify possible clinical predictors for no-refl ow in patients with AMI after primary percutaneous coronary intervention(PCI).METHODS: A total of 312 consecutive patients with AMI who had been treated from January 2008 to December 2010 at the Cardiology Department of East Hospital, Tongji University School of Medicine were enrolled in this study. Inclusion criteria were:(i) patients underwent successfully primary PCI within 12 hours after the appearance of symptoms; or(ii) patients with ischemic chest pain for more than 12 hours after a successful primary PCI within 24 hours after appearance of symptoms. Exculsion criteria were:(i) coronary artery spasm;(ii) diameter stenosis of the culprit lesion was ≤50% and coronary blood f low was normal;(iii) patients with severe left main coronary or multivessel disease, who had to require emergency revascularization. According to thrombolysis in myocardial infarction(TIMI), the patients were divided into a reflow group and a no-reflow group. The clinical data, angiography f indings and surgical data were compared between the two groups. Univariate and multivariate logistic regressions were used to determine the predictors for no-ref low.RESULTS: Fifty-four(17.3%) of the patients developed NR phenomenon after primary PCI. Univariate analysis showed that age, time from onset to reperfusion, systolic blood pressure(SBP) on admission, Killip class of myocardial infarction, intra-aortic balloon pump(IABP) use before primary PCI, TIMI flow grade before primary PCI, type of occlusion, thrombus burden on baseline angiography, target lesion length, reference luminal diameter and method of reperfusion were correlated with no-reflow(P<0.05 for all). Multiple logistic regression analysis identified that age >65 years [OR=1.470, 95% confi dence interval(CI) 1.460–1.490, P=0.007], long time from onset to reperfusion >6 hours(OR=1.270, 95%CI 1.160–1.400, P=0.001), low SBP on admission <100 mmHg(OR=1.910, 95%CI 1.018–3.896, P=0.004), IABP use before PCI(OR= 1.949, 95%CI 1.168–3.253, P=0.011), low(≤1) TIMI fl ow grade before primary PCI(OR=1.100, 95%CI 1.080–1.250, P<0.001), high thrombus burden(OR=1.600, 95%CI 1.470–2.760, P=0.030), and long target lesion(OR=1.948, 95%CI 1.908–1.990, P=0.019) on angiography were independent predictors of no-refl ow.CONCLUSION: The occurrence of no-refl ow after primary PCI for acute myocardial infarction can predict clinical, angiographic and procedural features.Hua Zhou Xiao-yan He Shao-wei Zhuang Juan Wang Yan Lai Wei-gang Qi Yi-an Yao Xue-bo Liu 2014World Journal of Emergency Medicine2014,5,2:46
3Transplantation 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 2017Science China(Life Sciences)2017,60,4:39

5Accelerated Degradation Reliability Modeling and Test Data Statistical Analysis of Aerospace Electrical Connector显示文摘As few or no failures occur during accelerated life test,it is difficult to assess reliability for long-life products with traditional life tests.Reliability assessment using degradation data of product performance over time becomes a significant approach.Aerospace electrical connector is researched in this paper.Through the analysis of failure mechanism,the performance degradation law is obtained and the statistical model for degradation failure is set up;according to the research on statistical analysis methods for degradation data,accelerated life test theory and method for aerospace electrical connector based on performance degradation is proposed by improving time series analysis method,and the storage reliability is assessed for Y11X series of aerospace electrical connector with degradation data from accelerated degradation test.The result obtained is basically consistent with that obtained from accelerated life test based on failure data,and the two estimates of product's characteristic life only have a difference of 8.7%,but the test time shortens about a half.As a result,a systemic approach is proposed for reliability assessment of highly reliable and long-life aerospace product.CHEN Wenhua LIU Juan GAO Liang PAN Jun ZHOU Shengjun 2011Chinese Journal of Mechanical Engineering2011,24,6:22
6Improved survival ratios correlate with myeloid dendritic cell restoration in acute-on-chronic liver failure patients receiving methylprednisolone therapy显示文摘Acute-on-chronic 肝失败(ACLF ) 是严重威胁生活的复杂并发症。肝移植是唯一的可得到的治疗学的选择;然而,几限制在病人限制了它的使用。为 ACLF 的可选的治疗收到了很多利息的 corticosteroids 的使用。在它的使用后面的基本原理是在开始并且永久维持肝的损坏的免疫系统的可能的角色。以便估计在 myeloid 之间的关系树枝状的房间(mDCs ) 和 methylprednisolone (MP ) 的功效为肝炎 B 病毒(HBV ) 的治疗联系了 ACLF 病人,我们招募了在 10 天的间隔接受了 MP 治疗的 30 个联系 HBV 的 ACLF 病人;26 个病人接待了保守人士医药(厘米) 管理作为控制。DC 子集的功能与健康题目相比在这些 ACLF 病人是更低的。与幸存者相比,另外, dead/transplanted 病人在两个组有更低的功能的 mDC。而且,一在基线的 mDC 的减少的数字与 ACLF 病人的高死亡被联系。重要地, MP 治疗在 28 天的死亡导致了重要减少,并且所有 MP 病人在 10 天 MP 治疗以内在传播 mDC 数字展出了起始的快速的减少。随后, MP 幸存者在超过 30 % 减少在全部的 bilirubin 层次伴随的 mDC 数字显示了连续增加;。然而, MP dead/transplanted 病人与幸存者相比缺乏这些顺序的回答。这条证据强烈建议在基线和在治疗的结束的 mDC 数字的恢复的更高的 mDC 数字可以在 ACLF 病人为对 corticosteroid 治疗的有利反应代表一个预示的标记。Juan Zhao Ji-Yuan Zhang Hong-Wei Yu Yu-Lan He Jing-Jing Zhao Juan Li Yue-Ke Zhu Qin-Wei Yao Jin-Huan Wang Hai-Xia Liu Shu-Yun Shi Zheng-Sheng Zou Xiang-Sheng Xu Chun-Bao Zhou Fu-Sheng Wang Qing-Hua Meng 2012Cellular & Molecular Immunology2012,9,5:23

9Protective effect of selenium-enriched lactobacilluson CCI_4-induced liver injury in mice and its possible mechanisms显示文摘AIM: To study the protective effects and mechanisms of Se-enriched lactobacillus on liver injury caused by carbon tetrachloride (CCl4) in mice.MWTHODS: Seventy-two ICR mice were randomly divided into four groups: normal group, CCl4-induced model group,low Se-enriched lactobacillus treatment group (L-Se group),and high Se-enriched lactobacillus treatment group (H-Se group). During a 3-wk experimental period, the common complete diet was orally provided daily for normal group and model group, and the mice in L-Se and H-Se groups were given a diet with 2 and 4 mg of organoselenium from Se-enriched lactobacillus per kg feed, respectively. From the 2nd wk of experiment, the model group, L-Se group,and H-Se group received abdominal cavity injection of olive oil solution containing 500 mL/L CCl4 (0.07 mL/100 g body mass) to induce liver injury, and the normal group was given olive oil on every other day for over 2 wk. In the first 2 wk post injection with CCl4, mice in each group were killed. The specimens of blood, liver tissue, and macrophages in abdominal cavity fluid were taken. Then the activities of the following liver tissue injury-associated enzymes including glutathione peroxidase (GSH-Px), superoxide dismutase (SOD), alanine aminotransferase (ALT) and aspartate aminotransferase (AST) as well as malondialdehyde (MDA) content were assayed. Changes of phagocytic rate and phagocytic index in macrophages were observed with Wright-Giemsa stain. Plasma TNF-α level was measured by radioimmunoassay. The level of intracellular free Ca2+ ([Ca2+]i) in hepatocytes was detected under a laser scanning confocal microscope.RESULTS: During the entire experimental period, the AST and ALT activities in liver were greatly enhanced by CCl4 and completely blunted by both low and high doses of Se-enriched lactobacillus. The Se-enriched lactobacillus-protected liver homogenate GSH-Px and SOD activities were higher or significantly higher than those in model group and were close to those in normal group. CCl4 significantly increased MDA content in liver homogenates, while administration of Se-enriched lactobacillus prevented MDA elevation. Phagocytic rate and phagocytic index of macrophages decreased after CCl4 treatment compared to those in normal control, but they were dramatically rescued by Se-enriched lactobacillus, showing a greatly higher phagocytic function compared to model group. CCl4 could significantly elevate plasma TNF-α and hepatocyte [Ca2+]i level, which were also obviously prevented by Se-enriched lactobacillus.CONCLUSION: Se-enriched lactobacillus can intervene in CCl4-induced liver injury in mice by enhancing macrophage function activity to keep normal and beneficial effects,elevating antioxidant-enzyme activities and reducing lipid peroxidation reaction, inhibiting excessive release of TNF-α,preventing the dramatic elevation of [Ca2+]i in hepatocytes.Long Chen Dao-Dong Pan Juan Zhou Ying-Zi Jiang 2005World Journal of Gastroenterology2005,11,37:19
10Infection with novel coronavirus(SARS-CoV-2)causes pneumonia in Rhesus macaques显示文摘The 2019 novel coronavirus(SARS-CoV-2)outbreak is a major challenge for public health.SARS-CoV-2 infection in human has a broad clinical spectrum ranging from mild to severe cases,with a mortality rate of^6.4%worldwide(based on World Health Organization daily situation report).However,the dynamics of viral infection,replication and shedding are poorly understood.Here,we show that Rhesus macaques are susceptible to the infection by SARS-CoV-2.After intratracheal inoculation,the first peak of viral RNA was observed in oropharyngeal swabs one day post infection(1 d.p.i.),mainly from the input of the inoculation,while the second peak occurred at 5 d.p.i.,which reflected on-site replication in the respiratory tract.Histopathological observation shows that SARS-CoV-2 infection can cause interstitial pneumonia in animals,characterized by hyperemia and edema,and infiltration of monocytes and lymphocytes in alveoli.We also identified SARS-CoV-2 RNA in respiratory tract tissues,including trachea,bronchus and lung;and viruses were also re-isolated from oropharyngeal swabs,bronchus and lung,respectively.Furthermore,we demonstrated that neutralizing antibodies generated from the primary infection could protect the Rhesus macaques from a second-round challenge by SARS-CoV-2.The non-human primate model that we established here provides a valuable platform to study SARS-CoV-2 pathogenesis and to evaluate candidate vaccines and therapeutics.Chao Shan Yan-Feng Yao Xing-Lou Yang Yi-Wu Zhou Ge Gao Yun Peng Lian Yang Xue Hu Jin Xiong Ren-Di Jiang Hua-Jun Zhang Xiao-Xiao Gao Cheng Peng Juan Min Ying Chen Hao-Rui Si Jia Wu Peng Zhou Yan-Yi Wang Hong-Ping Wei Wei Pang Zheng-Fei Hu Long-Bao Lv Yong-Tang Zheng Zheng-Li Shi Zhi-Ming Yuan 2020Cell Research2020,30,8:19

13Relationship between homocysteine level and prognosis of elderly patients with acute ischemic stroke treated by thrombolysis with recombinant tissue plasminogen activator显示文摘BACKGROUND Acute ischemic stroke(AIS)is mainly caused by cerebral blood flow disorders,which further leads to ischemic brain necrosis or encephalomalacia.The role of homocysteine(Hcy),an independent risk factor for cardiovascular disease,in the development of atherosclerosis is gradually revealed.However,studies are still rare and little is known about the relationship of Hcy level with the prognosis.AIM To explore the relationship between Hcy level and prognosis in elderly patients with AIS after thrombolytic therapy with recombinant tissue plasminogen activator(rtPA).METHODS A total of 120 patients with acute ischemic stroke who were admitted to Jingzhou Central Hospital and underwent recombinant tissue plasminogen activator treatment were randomly selected from January 2017 to December 2018.They were divided into two groups according to the level of Hcy,with 60 patients in each group.Patients with Hcy≥18.54 umol/L were included into a high-level group and those with Hcy<18.54 umol/L were included into a low-level group.The outcomes were analyzed in the two groups after the treatment.RESULTS The National institute of Health Stroke Scale(NIHSS)scores were significantly higher in the high-level group than in the low-level group before and 1 h after the treatment(P<0.05).There was no significant difference in NIHSS scores between the two groups at 12 and 24 h after the treatment(P>0.05).The Modified Rankin scale(MRS)scores were significantly higher in the high-level group than in the low-level group before and 1 h after the treatment(P<0.05).There was no significant difference in MRS scores between the two groups at 12 and 24 h after the treatment(P>0.05).NIHSS and MRS scores were positively correlated with the prognosis after thrombolytic therapy(P<0.05).CONCLUSION The level of Hcy is closely related to the prognosis of elderly patients with acute ischemic stroke,and after rtPA treatment,the prognosis of elderly patients is improved significantly.Juan Li Fan Zhou Feng-Xue Wu 2019World Journal of Clinical Cases2019,7,22:16
14Heterotopic pancreas in the gastrointestinal tract显示文摘Heterotopic pancreas is defined as pancreatic tissue found outside the usual anatomical location of the pancreas. It is often an incidental finding and can be found at different sites in the gastrointestinal tract. It may become clinically evident when complicated by pathological changes such as inflammation, bleeding, obstruction, and malignant transformation. In this report, a 60-year-old man with carcinoid syndrome caused by heterotopic pancreatic tissue in the duodenum is described, along with a 62-year-old man with abdominal pain caused by heterotopic pancreatic tissue in the gastric antrum. The difficulty of making an accurate diagnosis is highlighted. The patients remain healthy and symptom-free after follow-up of 1 year. Frozen sections may help in deciding the extent of resection intraoperatively. Although heterotopic pancreas is rare, it should be considered in the differential diagnosis of gastrointestinal stromal tumor.Zhou Yuan Jie Chen Qi Zheng Xin-Yu Huang Zhe Yang Juan Tang 2009World Journal of Gastroenterology2009,15,29:15
15Uric formaldehyde levels are negatively correlated with cognitive abilities in healthy older adults显示文摘Recent studies have shown that the abnormal accumulation of endogenous formaldehyde could be a critical factor in age-related cognitive decline. The aim of this study was to estimate the correlation between uric formaldehyde and general cognitive abilities in a community-based elderly population, and to measure the extent and direction in which the correlation varied with demographic characteristics. Using a double-blind design, formaldehyde in human urine was analyzed by high-performance liquid chromatography(n = 604), and general cognitive abilities were measured using the Montreal Cognitive Assessment(MoCA). Demographic characteristics, in terms of age, gender, residential region, and education were taken into consideration. We found that uric formaldehyde levels were inversely correlated with the MoCA score, and the concentration varied with demographic features: higher odds of a high formaldehyde level occurred among the less educated and those living in old urban or rural areas. In cytological experiments, the level of cellular formaldehyde released into the medium increased as SH-SY5Y and BV2 cells were incubated for three days. Formaldehyde in excess impairedthe processes of N2a cells and neurites of primary cultured rat hippocampal cells. However, removal of formaldehyde markedly rescued and regenerated the processes of N2a cells. These results demonstrated a negative correlation between the endogenous formaldehyde and general cognitive abilities. High formaldehyde levels could be a risk factor for cognitive impairment in older adults, and could be developed as a non-invasive marker for detection and monitoring of age-related cognitive impairment.Jing Yu Tao Su Ting Zhou Yingge He Jing Lu Juan Li Rongqiao He 2014Neuroscience Bulletin2014,30,2:14
16Salvianolate Reduces Murine Myocardial Ischemia and Reperfusion Injury via ERK1/2 Signaling Pathways in vivo显示文摘Objective:To analyze the effects of salvianolate on myocardial infarction in a murine in vivo model of ischemia and reperfusion(l/R) injury.Methods:Myocardial l/R injury model was constructed in mice by 30 min of coronary occlusion followed by 24 h of reperfusion and pretreated with salvianolate 30 min before l/R(SAL group).The SAL group was compared with SHAM(no l/R and no salvianolate),l/R(no salvianolate),and ischemia preconditioning(IPC) groups.Furthermore,an ERK1/2 inhibitor PD98059(1 mg/kg),and a phosphatidylinositol-3-kinase(PI3-K) inhibitor,LY294002(7.5 mg/kg),were administered intraperitoneal injection(i.p) for 30 min prior to salvianolate,followed by l/R surgery in LY and PD groups.By using a double staining method,the ratio of the infarct size(IS) to left ventricle(LV) and of risk region(RR) to LV were compared among the groups.Correlations between IS and RR were analyzed.Western-blot was used to detect the extracellular signal-regulated kinase 1/2(ERK1/2) and protein kinase B(AKT) phosphorylation changes.Results:There were no significant differences between RR to LV ratio among the SHAM,l/R,IPC and SAL groups(P>0.05).The SAL and IPC groups had IS of 26.1%± 1.4%and 22.3%±2.9%of RR,respectively,both of which were significantly smaller than the l/R group(38.5%±2.9%of RR,P<0.05,P<0.01,respectively).Moreover,the phosphorylation of ERK1/2 was increased in SAL group(P<0.05),while AKT had no significant change.LY294002 further reduced IS,whereas the protective role of salvianolate could be attenuated by PD98059,which increased the IS.Additionally,the IS was not linearly related to the RR(r=0.23,0.45,0.62,0.17,and 0.52 in the SHAM,l/R,SAL,LY and PD groups,respectively).Conclusion:Salvianolate could reduce myocardial l/R injury in mice in vivo,which involves an ERK1/2 pathway,but not a PI3-K signaling pathway.QI Jian-yong YU Juan HUANG Dong-hui GUO Li-heng WANG Lei HUANG Xin HUANG Hai-ding ZHOU Miao ZHANG Min-zhou Jiashin Wu 2017Chinese Journal of Integrative Medicine2017,23,1:14

19Effect of CO_2 Enrichment on the Growth and Nutrient Uptake of Tomato Seedlings显示文摘Exposing tomato seedlings to elevated CO2 concentrations may have potentially profound impacts on the tomato yield and quality. A growth chamber experiment was designed to estimate how different nutrient concentrations influenced the effect of elevated CO2 on the growth and nutrient uptake of tomato seedlings. Tomato (Hezuo 906) was grown in pots placed in controlled growth chambers and was subjected to ambient or elevated CO2 (360 or 720μL L-1) and four nutrient solutions of different strengths (1/2-, 1/4-, 1/8-, and 1/16-strength Japan Yamazaki nutrient solutions) in a completely randomized design. The results indicated that some agricultural characteristics of the tomato seedlings such as the plant height, stem thickness, total dry and fresh weights of the leaves, stems and roots, the G value (G value = total plant dry weight/seedling age), and the seedling vigor index (seedling vigor index = stem thickness/(plant height×total plant dry weight) increased with the elevated CO2, and the increases were strongly dependent on the nutrient solution concentrations, being greater with higher nutrient solution concentrations. The elevated CO2 did not alter the ratio of root to shoot. The total N, P, K, and C absorbed from all the solutions except P in the 1/8- and 1/16-strength nutrient solutions increased in the elevated CO2 treatment. These results demonstrate that the nutrient demands of the tomato seedlings increased at elevated CO2 concentrations.LI Juan ZHOU Jian-Min DUAN Zeng-Qiang DU Chang-Wen WANG Huo-Yan 2007Pedosphere2007,17,3:13
20Toxicity of the brominated flame retardant tris-(2,3-dibromopropyl) isocyanurate in zebrafish (Danio rerio)显示文摘Tris-(2,3-dibromopropyl) isocyanurate (TBC) is a heterocyclic brominated flame retardant that was recently detected in the environment in China.TBC is semi-volatile and can accumulate in the lipid of some species,but little is known about its effect on aquatic organisms.We exposed adult zebrafish to 0,0.25,1 and 4mg/L TBC for 28 d and measured the effect on survival,growth,histopathology,hormone levels,enzyme activity,and gene expression.TBC exposure had no effect on survival or growth.We observed significant damage to the liver and gill,including hepatocellular swelling and fatty degeneration in the liver as well as proliferation and edema of epithelial cells in the gills.In addition,exposure to 4mg/L TBC induced proliferation of goblet cells in the intestine of both sexes,acellular areas in the testis,and thinly scattered vitellogenic granules in vitellogenic oocytes.TBC exposure had no effect on the levels of thyroid hormones,testosterone,estradiol,liver superoxide dismutase activity,malondialdehyde content,and brain cholinesterase activity.By contrast,hepatic vitellogenin and cytochrome P4501A gene expression was significantly down-regulated in both male and female zebrafish in response to TBC exposure.Our results suggest that exposure to TBC causes a variety of potential reproductive and endocrine toxic effects.ZHANG Xu LI Juan CHEN MinJie WU Le ZHANG Chi ZHANG Jie ZHOU QunFang LIANG Yong 2011Chinese Science Bulletin2011,56,15:13
