12018 Chinese Pediatric Cardiology Society(CPCS) guideline for diagnosis and treatment of syncope in children and adolescents显示文摘Syncope belongs to the transient loss of consciousness(TLOC), characterized by a rapid onset, short duration, and spontaneous complete recovery. It is common in children and adolescents, accounting for 1% to 2% of emergency department visits.Recurrent syncope can seriously affect children's physical and mental health, learning ability and quality of life and sometimes cardiac syncope even poses a risk of sudden death. The present guideline for the diagnosis and treatment of syncope in children and adolescents was developed for guiding a better clinical management of pediatric syncope. Based on the globally recent development and the evidence-based data in China, 2018 Chinese Pediatric Cardiology Society(CPCS) guideline for diagnosis and treatment of syncope in children and adolescents was jointly prepared by the Pediatric Cardiology Society, Chinese Pediatric Society, Chinese Medical Association(CMA)/Committee on Pediatric Syncope, Pediatricians Branch, Chinese Medical Doctor Association(CMDA)/Committee on Pediatric Cardiology, Chinese College of Cardiovascular Physicians, Chinese Medical Doctor Association(CMDA)/Pediatric Cardiology Society, Beijing Pediatric Society, Beijing Medical Association(BMA). The present guideline includes the underlying diseases of syncope in children and adolescents, the diagnostic procedures, methodology and clinical significance of standing test and headup tilt test, the clinical diagnosis vasovagal syncope, postural orthostatic tachycardia syndrome, orthostatic hypotension and orthostatic hypertension, and the treatment of syncope as well as follow-up.Cheng Wang Yaqi Li Ying Liao Hong Tian Min Huang Xiangyu Dong Lin Shi Jinghui Sun Hongfang Jin Junbao Du Jindou An Jie Chen Mingwu Chen Qi Chen Sun Chen Yonghong Chen Zhi Chen Adolphus Kai-tung Chau Junbao Du Zhongdong Du Junkai Duan Hongyu Duan Xiangyu Dong Lin Feng Lijun Fu Fangqi Gong Yonghao Gui Ling Han Zhenhui Han Bing He Zhixu He Xiufen Hu Yimin Hua Guoying Huang Min Huang Ping Huang Yujuan Huang Hongfang Jin Mei Jin Bo Li Fen Li Tao Li Xiaohui Li Xiaoyan Liu Yan Li Haitao Lv Tiewei Lv Zipu Li Luyi Ma Silin Pan Yusheng Pang Hua Peng Yuming Qin Jie Shen Lin Shi Kun Sun Jinghui Sun Hong Tian Jie Tian Cheng Wang Hong Wang Lei Wang Jinju Wang Wendi Wang Yuli Wang Rongzhou Wu Tianhe Xia Yanyan Xiao Chunhong Xie Yanlin Xing Zhenyu Xiong Baoyuan Xu Yi Xu Hui Yan Shiwei Yang Qijian Yi Xia Yu Xianyi Yu Yue Yuan Hongyan Zhang Huili Zhang Li Zhang Qingyou Zhang Xi Zhang Yanmin Zhang Zhiwei Zhang Cuifen Zhao Bin Zhou Hua Zhu 2018Science Bulletin2018,63,23:54

3The efficacy and safety of endovascular recanalization of occluded large cerebral arteries during the subacute phase of cerebral infarction:a case series report显示文摘background Intravenous tissue plasminogen activator with or without mechanical thrombectomy during the acute phase are approved therapies for ischaemic stroke.Due to the short treatment time window(<6 hours)and often treatment failure,these patients would still have an intracranial arterial occlusion(IAO).It is unclear whether these patients can benefit from subsequent interventional recanalizationof their occluded artery in the subacute phase.In this retrospective study,we have examined the efficacy and safety in patients who have received either percutaneous transluminal angioplasty(PTA)or percutaneous transluminal angioplasty and stenting(PTAS)for IAO in the subacute phase of their stroke.Methods Patients with subacute symptomatic ischaemic stroke caused by IAO were assessed to identify the responsible artery and low perfusion areas by CT angiography,MR angiography or digital subtraction angiography.In eligible patients,a PTA or PTAS was performed to reopen the occluded artery.Regular antithrombotic therapy,use of statins,control of risk factors and rehabilitation therapy were prescribed after the procedure.All patients had regular follow-up up to 12 months.results PTA or PTAS was performed in 16 patients with cerebral infarction caused by IAO in the subacute phase.After the procedure,12 cases were recanalized,two were partially recanalized and two failed to open.One patient with left C6 segment occlusion of the carotid artery had a central retinal artery embolism after PTAS.The perioperative adverse events were 6.25%.At 3 months,the distribution of modified Rankin scale scores was 0(seven cases),1(three cases),2(five cases)and 3(one case).conclusion Selective PTA or PTAS could be performed in ischaemic stroke patients with a small infarct size and large area of hypoperfusion from an occluded large cerebral artery after the acute phase.It may improve neurological dysfunction and reduce the incidence of disability.Kangning Chen Xianhua Hou Zhenhua Zhou Guangjian Li Qu Liu Li Gui Jun Hu Shugui Shi 2017Stroke & Vascular Neurology2017,2,3:41
4Guidelines on multidisciplinary approaches for the prevention and management of diabetic foot disease(2020 edition)显示文摘In recent years,as living standards have continued to improve,the number of diabetes patients in China,along with the incidence of complications associated with the disease,has been increasing.Among these complications,diabetic foot disease is one of the main causes of disability and death in diabetic patients.Due to the differences in economy,culture,religion and level of medical care available across different regions,preventive and treatment methods and curative results for diabetic foot vary greatly.In multidisciplinary models built around diabetic foot,the timely assessment and diagnosis of wounds and appropriate methods of prevention and treatment with internal and external surgery are key to clinical practice for this pathology.In 2019,under the leadership of the Jiangsu Medical Association and Chinese Diabetes Society,the writing group for the Guidelines on multidisciplinary approaches for the prevention and management of diabetic foot disease(2020 edition)was established with the participation of scholars from the specialist areas of endocrinology,burn injury,vascular surgery,orthopedics,foot and ankle surgery and cardiology.Drawing lessons from diabetic foot guidelines from other countries,this guide analyses clinical practices for diabetic foot,queries the theoretical basis and grades and gives recommendations based on the characteristics of the pathology in China.This paper begins with assessments and diagnoses of diabetic foot,then describes treatments for diabetic foot in detail,and ends with protections for high-risk feet and the prevention of ulcers.This manuscript covers the disciplines of internal medicine,surgical,nursing and rehabilitation and describes a total of 50 recommendations that we hope will provide procedures and protocols for clinicians dealing with diabetic foot.Aiping Wang Guozhong Lv Xingbo Cheng Xianghua Ma Wei Wang Jianchao Gui JiHu Meng Lu Guoping Chu Jin’an Chen Hao Zhang Yiqiu Jiang Yuedong Chen Wengbo Yang Lin Jiang Houfa Geng Rendong Zheng Yihui Li Wei Feng Boey Johnson Wenjuan Wang Dalong Zhu Yin Hu 2020Burns & Trauma2020,8,1:34

6Process mineralogy of copper-nickel sulphide flotation by a cyclonic-static micro-bubble flotation column显示文摘In our study we investigated a refractory copper-nickel sulfide ore separation by using a cyclonic-static micro-bubble flotation column (FCSMC). The process mineralogy of the main products was studied. Using a scanning electron microscope-energy dispersive system (SEM-EDS) and an X-ray spectrometer the mineral category and content of samples were analyzed. By using a mineral liberation analyzer (MLA) the mineral liberation characteristics were revealed. It is shown that in roughing feed the monomers liberation degree of nickel pyrite and chalcopyrite take up 84.11% and 88.82%, respectively. In tailings, the lost nickel pyrite and chalcopyrite are mainly monomers. Therefore, strengthening the micro-fine particle recovery capacity is the key to increase recovery.CAO Yi-jun GUI Xia-hui MA Zi-long YU Xiao-xia CHEN Xiao-dong ZHANG Xiu-pin 2009Mining Science and Technology2009,19,6:25

8The Impacts of Maternal Gestational Diabetes Mellitus (GDM) on Fetal Hearts显示文摘Objective To evaluate the fetal cardiac function in gestational diabetes mellitus (GDM) pregnancies under different maternal glycemic controls.Methods Forty four GDM mothers received 78 fetal echocardiographic evaluations at three gestational periods (<28,28-34 and ≥34 weeks) and were divided into poorly-(DM1) and well-(DM2) controlled groups according to their glycemic control at examination.Seventy uncomplicated mothers were selected as controls.Parameters of fetal cardiac anatomy and function were measured and analyzed.Results GDM fetuses' cardiac ventricular walls were thicker than controls',and the differences between DM1 and DM2 were not significant except for end-diastolic left ventricular walls.In both GDM groups,the aortic flow velocities increased earlier than pulmonary artery and DM1 fetuses changed earlier than DM2 ones.GDM fetuses' left atrial shortening fraction was smaller than the controls' in the period of ≥34 weeks and negatively correlated with thicknesses of left ventricular walls and interventricular septum in DM1 fetuses (r=-0.438 and -0.506).The right ventricular diastolic function in DM1 and DM2 fetuses decreased after the period of 28-34 weeks and in the period of ≥34 weeks respectively.Tei index of both left and right ventricles increased in DM1 group after the period of<28 weeks and in DM2 group only in the period of ≥34 weeks,with no significant differences between DM1 and DM2 groups in this period.Conclusion Fetuses of GDM mothers showed cardiac function impairments.Good maternal glycemic control may delay the impairments,but cannot reduce the degree.Some cardiac changes in GDM fetuses were similar to those in pregestational diabetic pregnancies except for several parameters and their changing time.CHU Chen GUI Yong Hao PEN Yun Yun SHI Li Ye 2012Biomedical and Environmental Sciences2012,25,1:20
9Optimal time for mesenchymal stem cell transplantation in rats with myocardial infarction显示文摘Background:Bone marrow mesenchymal stem cell (MSC) transplantation is a promising strategy in the treatment of myocardial infarction (MI). However, the time for transplanting cells remains controversial. The aim of this study was to find an optimal time point for cell transplantation. Methods: MSCs were isolated and cultured from Sprague-Dawley (SD) rats. MI model was set up in SD rats by permanent ligation of left anterior descending coronary artery. MSCs were directly injected into the infarct border zone at 1 h, 1 week and 2 weeks after MI, respectively. Sham-operated and MI control groups received equal volume of phosphate buffered saline (PBS). At 4 weeks after MI, cardiac function was assessed by echocardiography; vessel density was analyzed on hematoxylin-eosin stained slides by light microscopy; the apoptosis of cardiomyocytes was evaluated by terminal deoxynucleotidyl transferase-mediated dUTP nick end-labeling (TUNEL) assay; the expressions of proteins were analyzed by Western blot. Results: MSC transplantation improved cardiac function, reduced the apoptosis of cardiomyocytes and increased vessel density. These benefits were more obvious in 1-week group than in 1-h and 2-week groups. There are more obvious in-creases in the ratio of bcl-2/bax and the expression of vascular endothelial growth factor (VEGF) and more obvious decreases in the expression of cleaved-caspase-3 in 1-week group than those in other two groups. Conclusion: MSC transplantation was beneficial for the recovery of cardiac function. MSC transplantation at 1 week post-MI exerted the best effects on increases of cardiac function, anti-apoptosis and angiogenesis.Chen-yang JIANG Chun GUI Ai-na HE Xin-yang HU Jie CHEN Yun JIANG Jian-an WANG 2008Journal of Zhejiang University-Science B(Biomedicine & Biotechnology)2008,9,8:18
10Antioxidant and Anti-inflammatory Capacity of Ferulic Acid Released from Wheat Bran by Solid-state Fermentation of Aspergillus niger显示文摘Objective A strain of Aspergillus niger(A. niger), capable of releasing bound phenolic acids from wheat bran, was isolated. This strain was identified by gene sequence identification. The antioxidant and anti-inflammatory capacity of ferulic acid released from wheat bran by this A. niger strain(FA-WB) were evaluated. Methods Molecular identification techniques based on PCR analysis of specific genomic sequences were conducted; antioxidant ability was examined using oxygen radical absorbance capacity(ORAC), cellular antioxidant activity(CAA) assays, and erythrocyte hemolysis assays. RAW264.7 cells were used as a model to detect anti-inflammatory activity. Results The filamentous fungal isolate was identified to be A. niger. ORAC and CAA assay showed that FA-WB had better antioxidant activity than that of the ferulic acid standard. The erythrocyte hemolysis assay results suggested that FA-WB could attenuate AAPH-induced oxidative stress through inhibition of reactive oxy gen species(ROS) generation. FA-WB could significantly restore the AAPH-induced increase in intracellular antioxidant enzyme activities to normal levels as well as inhibit the intracellular malondialdehyde formation. TNF-?, IL-6, and NO levels indicated that FA-WB can inhibit the inflammation induced by lipopolysaccharide(LPS). Conclusion Ferulic acid released from wheat bran by a new strain of A. niger had good anti-inflammatory activity and better antioxidant ability than standard ferulic acid.YIN Zhi Na WU Wen Jia SUN Chong Zhen LIU Hui Fan CHEN Wen Bo ZHAN Qi Ping LEI Zhuo Gui XIN Xuan MA Juan Juan YAO Kun MIN Tian ZHANG Meng Meng WU Hui 2019Biomedical and Environmental Sciences2019,32,1:14

12Neuroprotective effects of tetrandrine against vascular dementia显示文摘Tetrandrine is one of the major active ingredients in Menispermaceae Stephania tetrandra S.Moore,and has specific therapeutic effects in ischemic cerebrovascular disease.Its use in vascular dementia has not been studied fully.Here,we investigated whether tetrandrine would improve behavioral and cellular impairments in a two-vessel occlusion rat model of chronic vascular dementia.Eight weeks after model establishment,rats were injected intraperitoneally with 10 or 30 mg/kg tetrandrine every other day for 4 weeks.Behavioral assessment in the Morris water maze showed that model rats had longer escape latencies in training trials,and spent less time swimming in the target quadrant in probe trials,than sham-operated rats.However,rats that had received tetrandrine showed shorter escape latencies and longer target quadrant swimming time than untreated model rats.Hematoxylin-eosin and Nissl staining revealed less neuronal necrosis and pathological damage,and more living cells,in the hippocampus of rats treated with tetrandrine than in untreated model rats.Western blot assay showed that interleukin-1β expression,and phosphorylation of the N-methyl-D-aspartate 2B receptor at tyrosine 1472,were lower in model rats that received tetrandrine than in those that did not.The present findings suggest that tetrandrine may be neuroprotective in chronic vascular dementia by reducing interleukin-1β expression,N-methyl-D-aspartate receptor 2B phosphorylation at tyrosine 1472,and neuronal necrosis.Yan-ling Lv Ze-zhi Wu Li-xue Chen Bai-xue Wu Lian-lian Chen Guang-cheng Qin Bei Gui Ji-ying Zhou 2016Neural Regeneration Research2016,11,3:13

14Increase of TNFα-stimulated Osteoarthritic Chondrocytes Apoptosis and Decrease of Matrix Metalloproteinases 9 by NF-κB Inhibition显示文摘Objective To investigate the in vitro effect of caffeic acid phenethyl ester(CAPE),a NF-κB inhibitor,on the apoptosis of osteoarthritic(OA)chondrocytes and on the regulation of the gelatinases matrix metalloproteinase 2(MMP-2)and matrix metalloproteinase 9(MMP-9).Methods Annexin V-FITC/propidium iodide(PI)labeling and western blotting were used to observe and determine the apoptosis in TNFα-stimulated primary cultured osteoarthritic chondrocytes.Also,gelatin zymography was applied to examine MMP-2 and MMP-9 activities in supernatants.Results It was confirmed by both flow cytometry and western blotting that chondrocytes from OA patients have an apoptotic background.Use of CAPE in combination with 10 ng/mL of TNFα for 24 h facilitated the apoptosis.MMP-9 in the supernatant could be autoactivated(from proMMP-9 to active MMP-9),and the physiologic calcium concentration(2.5 mmol/L)could delay the autoactivation of MMP-9.The activities of MMP-2 and MMP-9 in the fresh supernatant increased significantly in response to stimulation by 10 ng/mL of TNFα for 24 h.The stimulatory effect of TNFα just on proMMP-9 was counteracted significantly by CAPE.Conclusion NF-κB could prevent chondrocytes apoptosis though its activation was attributed to the increase of proMMP-9 activity induced by TNFα(a pro-apoptotic factor).Therefore,therapeutic NF-κB inhibitor was a 'double-edged swords' to the apoptosis of chondrocytes and the secretion of MMP-9.WANG Yan LI De Ling ZHANG Xin Bo DUAN Yuan Hui WU Zhi Hong HAO Dong Sheng CHEN Bao Sheng QIU Gui Xing 2013Biomedical and Environmental Sciences2013,26,4:13

16PARylation regulates stress granule dynamics, phase separation, and neurotoxicity of disease-related RNA-binding proteins显示文摘Mutations in RNA-binding proteins (RBPs) localized in ribonucleoprotein (RNP) granules, such as hnRNP A1 and TDP-43, promote aberrant protein aggregation, which is a pathological hallmark of various neurodegenerative diseases, such as amyotrophic lateral sclerosis (ALS) and frontotemporal dementia (FTD). Protein posttranslational modifications (PTMs) are known to 佗gulate RNP granules. In this study, we investigate the function of poly(ADP-ribosyl)ation (PARylation), an important PTM involved in DNA damage repair and cell death, in RNP granule-related neurodegeneration. We reveal that PARylation levels are a major regulator of the assembly-disassembly dynamics of RNP granules containing disease-related RBPs, hnRNP A1 and TDP-43. We find that hnRNP A1 can both be PARylated and bind to PARylated proteins or poly(ADP-ribose)(PAR). We further uncover that PARylation of hnRNP A1 at K298 controls its nucleocytoplasmic transport, whereas PAR-binding via the PAR-binding motif (PBM) of hnRNP Al regulates its association with stress granules. Moreover, we reveal that PAR not only dramatically enhances the liquid-liquid phase separation of hnRNP A1, but also promotes the co-phase separation of hnRNP A1 and TDP-43 in vitro and their interaction in vivo. Finally, both genetic and pharmacological inhibition of PARP mitigates hnRNP Al- and TDP-43-mediated neurotoxicity in cell and Drosophila models of ALS. Together, our findings suggest a novel and crucial role for PARylation in regulating the dynamics of RNP granules, and that dysregulation in PARylation and PAR levels may con tribute to ALS disease pathoge nesis by promoting protei n aggregation.Yongjia Duan Aiying Du Jinge Gu Gang Duan Chen Wang Xinrui Gui Zhiwei Ma Beituo Qian Xue Deng Kai Zhang Le Sun Kuili Tian Yaoyang Zhang Hong Jiang Cong Liu Yanshan Fang 2019Cell Research2019,29,3:13

19Instability mechanism and control technology of soft rock roadway affected by mining and high confined water显示文摘Based on deformation and failure characteristics of the second belt conveyor roadway at level II of Zhuxianzhuang coal mine, laboratory experiments, numerical calculation and field test were adopted to analyze the composition and microstructure of mudstone, the law of mudstone hydration and its strength weakening induced by water, the characteristics of surrounding rock deformation and failure under the action of confined water. Results showed that montmorillonite clay minerals accounted for as much as 76% of mudstone, with a large number of pores existing in the microstructure. Besides, as the molecular structure of montmorillonite changed, mudstone microstructure damage occurred with the macroscopic manifestation of its rheological instability. Weakening degree of confined water on residual strength of mudstone was almost 50%. The instability mechanism of soft rock roadway caused by high confined water is that surrounding rock circulates the process of ‘‘fracture-seepage-mud ding-closed'' twice, which weakens its strength and leads to roadway instability. A combined support technology, namely the, ‘‘high-toughness sealing layer + hollow grouting cables + full-length anchoring bolts with deep borehole'' was proposed. Based on field observation, the soft rock roadway was controlled effectively, which also verified the effectiveness of new control technology for surrounding rock.Li Guichen Jiang Zuohan Lv Chuangxin Huang Chao Chen Gui Li Mingyuan 2015International Journal of Mining Science and Technology2015,25,4:11
