3Deep seismic reflection profile across the juncture zone between the Tarim Basin and the West Kunlun Mountains显示文摘Fine structures of the crust and upper mantle of the basin-and-range juncture on the northwestern margin of the Qinghai-Tibetan Plateau are first delineated by the deep seismic reflection profile across the juncture zone between the Tarim Basin and the West Kunlun Mountains. Evidence is found for the northward subduction of the northwest marginal lithosphere of the Qinghai-Tibetan Plateau and its collision with Tarim lithosphere beneath the West Kunlun Mountains. The lithosphere image of the face-to-face subduction and collision determines the coupling relationship between the Tarim Basin and the West Kunlun Mountains at the lithosphere scale and reflects the process of continent- continent collision.GAO Rui HUANG Dongding LU Deyuan QIAN Guihua LI Yingkang KUANG Chaoyang Li Qiusheng LI Pengwu Feng Rujin Guan Ye 2000Chinese Science Bulletin2000,45,24:30
4Differences in symptoms and pre-hospital delay among acute myocardial infarction patients according to ST-segment elevation on electrocardiogram: an analysis of China Acute Myocardial Infarction (CAMI) registry显示文摘Background: Approximately 70% patients with acute myocardial infarction (AMI) presented without ST-segment elevation on electrocardiogram. Patients with non-ST segment elevation myocardial infarction (NSTEMI) often presented with atypical symptoms, which may be related to pre-hospital delay and increased risk of mortality. However, up to date few studies reported detailed symptomatology of NSTEMI, particularly among Asian patients. The objective of this study was to describe and compare symptoms and presenting characteristics of NSTEMI vs. STEMI patients. Methods: We enrolled 21,994 patients diagnosed with AMI from China Acute Myocardial Infarction (CAMI) Registry between January 2013 and September 2014. Patients were divided into 2 groups according to ST-segment elevation: ST-segment elevation (STEMI) group and NSTEMI group. We extracted data on patients' characteristics and detailed symptomatology and compared these variables between two groups. Results: Compared with patients with STEMI (N=16,315), those with NSTEMI (N=5679) were older, more often females and more often have comorbidities. Patients with NSTEMI were less likely to present with persistent chest pain (54.3% vs.71.4%), diaphoresis (48.6% vs.70.0%), radiation pain (26.4% vs.33.8%), and more likely to have chest distress (42.4% vs.38.3%) than STEMI patients (all P<0.0001). Patients with NSTEMI were also had longer time to hospital. In multivariable analysis, NSTEMI was independent predictor of presentation without chest pain (odds ratio: 1.974, 95% confidence interval:1.849-2.107). Conclusions: Patients with NSTEMI were more likely to present with chest distress and pre-hospital patient delay compared with patients with STEMI. It is necessary for both clinicians and patients to learn more about atypical symptoms of NSTEMI in order to rapidly recognize myocardial infarction.Rui Fu Chen-Xi Song Ke-Fei Dou Jin-Gang Yang Hai-Yan Xu Xiao-Jin Gao Qian-Qian Liu Han Xu Yue-Jin Yang 2019Chinese Medical Journal2019,,5:29
5Relationship between Cognition Function and Hippocampus Structure after Long-term Microwave Exposure显示文摘Objective To analyze the effects of long-term microwave exposure on hippocampal structure and function in the rat.Methods Experiments were performed on 184 male Wistar rats(three exposure groups and a sham group).Microwaves were applied daily for 6 min over 1 month at average power densities of 2.5,5,and 10 mW/cm2.Learning and memory abilities were assessed by Morris water maze.High performance liquid chromatography was used to detect neurotransmitter concentrations in the hippocampus.Hippocampal structures were observed by histopathological analysis.Results Following long-term microwave exposure there was a significant decrease in learning and memory activity in the 7 d,14 d,and 1 m in all three microwave exposure groups.Neurotransmitter concentrations of four amino acids(glutamate,aspartic acid,glycine,and gamma-aminobutyric acid) in hippocampus were increased in the 2.5 and 5 mW/cm2 groups and decreased in the 10 mW/cm2 group.There was evidence of neuronal degeneration and enlarged perivascular spaces in the hippocampus in the microwave exposure groups.Further,mitochondria became swollen and cristae were disordered.The rough endoplasmic reticulum exhibited sacculated distension and there was a decrease in the quantity of synaptic vesicles.Conclusion These data suggest that the hippocampus can be injured by long-term microwave exposure,which might result in impairment of cognitive function due to neurotransmitter disruption.ZHAO Li PENG Rui Yun WANG Shui Ming WANG Li Feng GAO Ya Bing DONG Ji LI Xiang SU Zhen Tao 2012Biomedical and Environmental Sciences2012,25,2:27
6Solvothermal-Assisted Exfoliation Process to Produce Graphene with High Yield and High Quality显示文摘Monolayer and bilayer graphene sheets have been produced by a solvothermal-assisted exfoliation process in a highly polar organic solvent,acetonitrile,using expanded graphite(EG)as the starting material.It is proposed that the dipole-induced dipole interactions between graphene and acetonitrile facilitate the exfoliation and dispersion of graphene.The facile and effective solvothermal-assisted exfoliation process raises the low yield of graphene reported in previous syntheses to 10 wt%12 wt%.By means of centrifugation at 2000 rpm for 90 min,monolayer and bilayer graphene were separated effectively without the need to add a stabilizer or modifi er.Electron diffraction and Raman spectroscopy indicate that the resulting graphene sheets are high quality products without any signifi cant structural defects.Wen Qian Rui Hao Yanglong Hou Yuan Tian Chengmin Shen Hongjun Gao Xuelei Liang 2009Nano Research2009,2,9:28

8Theranostic nanoparticles with tumor-specific enzyme-triggered size reduction and drug release to perform photothermal therapy for breast cancer treatment显示文摘Although progress has been indeed made by nanomedicines, their efficacies for cancer treatment remain low, consequently leading to failures in translation to clinic. To improve the drug delivery efficiency,nanoparticles need to change size so as to fully utilize the enhanced permeability and retention(EPR) effect of solid tumor, which is the golden principle of nanoparticles used for cancer treatment. Herein, we employed cationic small-sized red emission bovine serum albumin(BSA) protected gold nanocluster(Au NC@CBSA,21.06 nm) to both load indocyanine green(ICG) and act as imaging probe to realize theranostic. Then Au NC@CBSA-ICG was fabricated with negatively charged hyaluronic acid(HA) to form Au NC@CBSAICG@HA, which was about 200 nm to easily retain at tumor site and could be degraded by tumor-specific hyaluronidase into small nanoparticles for deep tumor penetration. The HA shell also endowed Au NC@CBSA-ICG@HA with actively targeting ability and hyaluronidase-dependent drug release. Furthermore, the quenching and recovery of fluorescence revealed the interaction between ICG and carrier, which was essential for the investigation of pharmacokinetic profiles. No matter in vitro or in vivo, Au NC@CBSAICG@HA showed markedly anti-tumor effect, and could suppress 95.0% of tumor growth on mice breast cancer model. All results demonstrated Au NC@CBSA-ICG@HA was potential for breast cancer therapy.Rui Liu Chuan Hu Yuanyuan Yang Jingqing Zhang Huile Gao 2019Acta Pharmaceutica Sinica B2019,9,2:24
9Effect and Safety of Guanxinning Tablet(冠心宁片) for Stable Angina Pectoris Patients with Xin(Heart)-Blood Stagnation Syndrome:A Randomized,Multicenter,Placebo-Controlled Trial显示文摘Objective: To investigate the effect and safety of Guanxinning Tablet(冠心宁片, GXN) for the treatment of stable angina pectoris patients with Xin(Heart)-blood stagnation syndrome(XBSS). Methods: One hundred and sixty stable angina pectoris patients with XBSS were randomly assigned to receive GXN(80 cases) or placebo(80 cases, Guanxinning simulation tablets, mainly composed of lactose), 4 tablets(0.38 g/tablet), thrice daily for 12 weeks. After treatment, an exercise stress test(treadmill protocol), Chinese medicine(CM) syndrome score, electrocardiogram(ECG), and nitroglycerin withdrawal rate were evaluated and compared in the patients between the two groups. Meanwhile, adverse events(AEs) were evaluated during the whole clinical trial. Results: Compared with the control group, the time extension of exercise duration in the GXN group increased 29.28±17.67 s after treatment(P>0.05);moreover, the change of exercise duration in the GXN group increased 63.10±96.96 s in subgroup analysis(P<0.05). The effective rates of angina pectoris, CM syndrome and ECG as well as nitroglycerin withdrawal rate were 81.33%, 90.67%, 45.76%, and 70.73%, respectively in the GXN group, which were all significantly higher than those in the control group(40.58%, 75.36%, 26.92%, 28.21%, respectively, P<0.05). Conclusion: GXN was a safe and effective treatment for stable angina pectoris patients with XBSS at a dose of 4 tablets, thrice daily.SUN Ming-yue MIAO Yang JIN Min DONG Yao-rong LIU Shu-rong WANG Mu-lan GAO Rui 2019Chinese Journal of Integrative Medicine2019,25,9:22
10Clinical significance of diabetes on symptom and patient delay among patients with acute myocardial infarction——an analysis from China Acute Myocardial Infarction(CAMI) registry显示文摘Background Diabetes is frequently associated with poor prognosis among acute myocardial infarction(AMI)patients.Patients with these comorbidities often have atypical symptoms and subsequent delay in treatment.Few studies have reported detailed AMI symptoms in patients with diabetes.This study compared AMI symptoms and presentation characteristics between diabetics and non-diabetics.Methods We included patients from the China AMI registry diagnosed with AMI between January 2013 and September 2014.Baseline characteristics,symptomology,and delay in treatment were compared between diabetics and non-diabetics.Multivariable logistic regression analysis was used to explore independent predictors of atypical symptoms.Results A total of 4450(20.2%)patients had diabetes.They were older,more often women,higher in body mass index,and more likely to have non-ST segment elevation myocardial infarction.Fewer diabetic patients presented with persistent precordial chest pain(63.1%vs.68%,P<0.0001),diaphoresis(60.1%vs.65.6%,P<0.0001),fatigue(16.7%vs.18.3%,P=0.0123),and incontinence(0.4%vs.0.7%,P=0.0093).Time to hospital presentation was longer among patients with diabetes than those without.In multivariable analysis,diabetes was identified as an independent predictor of atypical symptoms(OR:1.112,95%CI:1.034?1.196).Conclusions Our study is the first large-scale study providing evidence that diabetics are less likely to present with typical chest pain and more likely to experience treatment delay when suffering from an AMI.Our results may increase clinician awareness of recognizing AMI patients rapidly to reduce diagnosis and treatment delay,particularly in the context of diabetes.Rui FU Si-Dong LI Chen-Xi SONG Jing-Ang YANG Hai-Yan XU Xiao-Jin GAO Yi XU Jian-Ping ZENG Jun-Nong LI Ke-Fei DOU Yue-Jin YANG on behalf of the CAMI Registry study group Beijing,China 2019Journal of Geriatric Cardiology2019,16,5:21
11Sutureless Intestinal Anastomosis with a Novel Device of Magnetic Compression Anastomosis显示文摘Objective To explore the feasibility and efficiency of a novel magnetic compression anastomats(MCAs) in intestinal anastomosis.Methods A total of 36 male mongrel canines underwent intestinal anastomosis using traditional hand-sewn(n=18) or a novel MCAs(n=18).We compared the anastomosis time,postoperative complications,bursting strength of anastomoses,gross appearance,and pathology between two groups at each time-point of follow-up.Results The mean anastomosis time with MCAs was significantly less than that with hand-sewn(8.50±1.95 vs.31.1±4.32 minutes,P<0.001).The blood stools and intussusceptions occurred in both groups during follow-up period.Only 1 mongrel canine receiving intestinal anastomosis by MCAs experienced anastomotic leakage.The average bursting pressure of anastomoses obtained from mongrel canines undergoing intestinal anastomosis by MCAs was significantly higher than that by traditional hand-sewn at 1 week's follow-up time(P<0.05).Gross appearance of the anastomoses constructed by MCAs was relatively smoother and flatter.Pathological evalution of anastomoses revealed that general inflammation was greater in hand-sewn anastomoses than magnetic anastomosis.Conclusion The magnetic compression anastomat is a safe and effective device of sutureless intestinal anastomosis in canine models.Chao Fan Jia Ma Hong-ke Zhang Rui Gao Jian-hui Li Liang Yu Zheng Wu Yi Lv 2011Chinese Medical Sciences Journal2011,26,3:20
12The ChinaMAP analytics of deep whole genome sequences in 10,588 individuals显示文摘Metabolic diseases are the most common and rapidly growing health issues worldwide.The massive population-based human genetics is crucial for the precise prevention and intervention of metabolic disorders.The China Metabolic Analytics Project(ChinaMAP)is based on cohort studies across diverse regions and ethnic groups with metabolic phenotypic data in China.Here,we describe the centralized analysis of the deep whole genome sequencing data and the genetic bases of metabolic traits in 10,588 individuals from the ChinaMAP.The frequency spectrum of variants,population structure,pathogenic variants and novel genomic characteristics were analyzed.The individual genetic evaluations of Mendelian diseases,nutrition and drug metabolism,and traits of blood glucose and BMI were integrated.Our study establishes a large-scale and deep resource for the genetics of East Asians and provides opportunities for novel genetic discoveries of metabolic characteristics and disorders.Yanan Cao Lin Li Min Xu Zhimin Feng Xiaohui Sun Jieli Lu Yu Xu Peina Du Tiange Wang Ruying Hu Zhen Ye Lixin Shi Xulei Tang Li Yan Zhengnan Gao Gang Chen Yinfei Zhang Lulu Chen Guang Ning Yufang Bi Weiqing Wang The ChinaMAP Consortium 2020Cell Research2020,30,9:20
13Effects of Tongxinluo-facilitated cellular cardiomyoplasty with autologous bone marrow-mesenchymal stem cells on postinfarct swine hearts显示文摘<正> Background Treatment of ischemic heart disease remains an important challenge,though there have been enormousprogresses in cardiovascular therapeutics.This study was conducted to evaluate whether Tongxinluo(TXL)treatmentaround the transplantation of mesenchymal stem cells(MSCs)can improve survival and subsequent activities ofimplanted cells in swine hearts with acute myocardial infarction(AMI)and reperfusion.Methods Twenty-eight Chinese mini-pigs were divided into four groups including a control group(n=7);group 2,administration of low-dose TXL alone from the 3rd day prior to AMI to the 4th day post transplantation(n=7);group 3,MSCs alone(n=7)and group 4,TXL+MSCs(n=7).AMI models were made by occlusion of the left anterior descendingcoronary artery for 90 minutes.Autologous bone marrow-MSCs(3×10~7 cells/animal)were then injected into thepost-infarct myocardium immediately after AMI and reperfusion.The survival and differentiation of implanted cells in vivowere detected by immunofluorescent analysis.The data of cardiac function were obtained at baseline(1 week aftertransplantation)and endpoint(6 weeks after transplantation)by single photon emission computed tomography(SPECT)and magnetic resonance imaging(MRI).Apoptosis was detected by TUNEL assay and the oxidative stress level wasinvestigated in the post-infarct myocardium at endpoint.Results At endpoint,there was less fibrosis and inflammatory cell infiltration with more surviving myocardium in group 4than in the control group.In group 4 the survival and differentiation of implanted MSCs were significantly improved morethan that seen in group 3 alone(P<0.0001);the capillary density was also significantly greater than in the control group,group 2 or 3 both in the infarcted zone(P<0.0001)and the peri-infarct zone(P<0.0001).MRI showed that parameters atbaseline were not significantly different between the 4 groups.At endpoint,regional wall thickening and the left ventricularejection fraction were increased while the left ventricular mass index,dyskinetic segments and infarcted size weredecreased only in group 4 compared with control group(P<0.0001).SPECT showed that the area of perfusion defectwas significantly decreased at endpoint only in group 4 compared with control group(P<0.0001).TUNEL assay indicatedthat TXL administration significantly decreased cell apoptosis in peri-infarct myocardium in groups 2 and 4.Furthermore,superoxide dismutase(SOD)significantly increased and malondialdehyde(MDA)decreased in groups 2 and 4 by theadministration of TXL.Conclusions Our study demonstrates the following:(1)immediate intramyocardial injection of MSCs after AMI andreperfusion resulted in limited survival and differentiation potential of implanted cells in vivo,thus being incapable ofbeneficially affecting post-hearts;(2)TXL-facilitation resulted in a significant survival and differentiation potential ofimplanted cells in vivo via inhibition of apoptosis and oxidative stress,accompanied by significant benefits in cardiacfunction.Chin Med J 2007;120(16)QIAN Hai-yan YANG Yue-jin HUANG Ji GAO Run-lin DOU Ke-fei YANG Guo-sheng LI Jian-jun SHEN Rui HE Zuo-xiang LU Min-jie ZHAO Shi-hua 2007Chinese Medical Journal2007,,16:19
14Collision Tectonics between the Tarim Block(Basin)and the Northwestern Tibet Plateau:New Observations from a Multidisciplinary Geoscientific Investigation in the Western Kunlun Mountains显示文摘New results from deep seismic reflection profiling, wide-angle reflection-refraction profiling and broadband seismic experiments reveal that a series of south-dipping reflectors occur on the southern margin of the Tarim block (basin). However, it is these south-dipping structures that are intercepted by another series of north-dipping reflectors at depths from 30 to about 150 km beneath the foreland of the W Kunlun Mountains. No evidence from the above geophysical data as well as geochemical and surface geological data indicate the southward subduction of the Tarim block beneath the W Kunlun Mountains (NW Tibet plateau), forming the so-called “two-sided subduction” model for the Tibet plateau as proposed by previous studies. So the authors infer that the tectonic interaction between the Tarim block and the W Kunlun block was chiefly affected by a “horizontal compression in opposite directions”, which brought about “face-to-face contact” between these two lithospheric blocks and led to the thickening, shortening and densifying of the lithosphere. Hence a “delamination” was formed due to the gravitational instability created by the thickening and densifying; then alkaline basic volcanic rocks (mainly shoshonite series) was erupted along the northern margin of the Tibet plateau owing to the delamination. This inference for the formation of the alkaline basic volcanics has been confirmed by recent geochemical and petrological studies in Tibet, indicating that different contacts control different magmatic activities: the alkali basalts are always developed in the “horizontal shortening boundary (contact)” on the northern margin of the Tibet plateau, while the muscovite granite and two-mica granite (leucogranite) in the “subductional contact” on the southern margin of the Tibet plateau.XIAO Xuchang LIU Xun GAO Rui Houn KAO LUO Zhaohua 2001Acta Geologica Sinica(English Edition)2001,75,2:19
15Detection of hepatitis C virus NS5 protein and genome in Chinese carcinoma of the extrahepatic bile duct and its significance显示文摘AIM To investigate the hepatitis C virus(HCV)infection in the tissues of carcinoma ofextrahepatic bile duct and study theircorrelation.METHODS HCV NS5 protein and HCV RNA weredetected by labeled streptavidin biotin(LSAB)method and in situ reverse transcriptionpolymerase chain reaction(IS-RT-PCR)insections of 51 cases of carcinoma ofextrahepatic bile duct and 34 cases of controlgroup(without malignant biliary disease).RESULTS In 51 cases of carcinoma ofextrahepatic bile duct,HCV NS5 protein wasdetected in 14(27.5%),which was clearlystained in the cytoplasm of cancer cell but not inthe nucleus or cell membrane.HCV RNA wasdetected in 18(35.4%),which was located inthe nucleus of cancer cell in 12 cases and in thecytoplasm in 6 cases.HCV NS5 protein and RNAcoexistence was found in 2 cases.In 34 cases ofcontrol group,HCV RNA was detected in 2(5.9%).HCV NS5 protein and RNA positive cellswere found either scattered or in clusters.CONCLUSION The prevalence of hepatitis C viral infection in the tissues of carcinoma ofextrahepatic bile duct was significantly higherthan in control group(X^2=9.808,P=0.002).The findings suggest a correlation between HCVinfection and carcinoma of extrahepatic bileduct,which is different from the traditionalviewpoint.HCV infection might be involved inthe development of carcinoma of extrahepaticbile duct.Ming Yi Chen Zhi Qiang Huang Le Zhen Chen Ya Bing Gao Rui Yun Peng De Wen Wang 2000World Journal of Gastroenterology2000,6,6:19

17Microwave Exposure Impairs Synaptic Plasticity in the Rat Hippocampus and PC12 Cells through Over-activation of the NMDA Receptor Signaling Pathway显示文摘Objective The aim of this study is to investigate whether microwave exposure would affect the N-methyl-D-aspartate receptor(NMDAR) signaling pathway to establish whether this plays a role in synaptic plasticity impairment. Methods 48 male Wistar rats were exposed to 30 m W/cm2 microwave for 10 min every other day for three times. Hippocampal structure was observed through H&E staining and transmission electron microscope. PC12 cells were exposed to 30 m W/cm2 microwave for 5 min and the synapse morphology was visualized with scanning electron microscope and atomic force microscope. The release of amino acid neurotransmitters and calcium influx were detected. The expressions of several key NMDAR signaling molecules were evaluated. Results Microwave exposure caused injury in rat hippocampal structure and PC12 cells, especially the structure and quantity of synapses. The ratio of glutamic acid and gamma-aminobutyric acid neurotransmitters was increased and the intracellular calcium level was elevated in PC12 cells. A significant change in NMDAR subunits(NR1, NR2 A, and NR2B) and related signaling molecules(Ca2+/calmodulin-dependent kinase II gamma and phosphorylated c AMP-response element binding protein) were examined. Conclusion 30 m W/cm2 microwave exposure resulted in alterations of synaptic structure, amino acid neurotransmitter release and calcium influx. NMDAR signaling molecules were closely associated with impaired synaptic plasticity.XIONG Lu SUN Cheng Feng ZHANG Jing GAO Ya Bing WANG Li Feng ZUO Hong Yan WANG Shui Ming ZHOU Hong Mei XU Xin Ping DONG Ji YAO Bin Wei ZHAO Li PENG Rui Yun 2015Biomedical and Environmental Sciences2015,28,1:16
