1Characteristics of vascular lesions in patients with posterior circulation infarction according to age and region of infarct显示文摘Patients with posterior circulation infarction underwent CT angiography and magnetic resonance angiography. Intracranial and extracranial vasculopathy was evaluated according to age group and location of stroke. Patients aged > 60 years and < 60 years had similar rates of vertebral artery dominance and vertebrobasilar artery developmental or origin anomalies. Vertebrobasilar artery stenosis or occlusion and tortuosity occurred more frequently in patients aged > 60 years than < 60 years. The rates of vertebrobasilar artery anomalies and tortuosity were high in patients with posterior circulation infarction. Vertebrobasilar artery tortuosity occurred more frequently in patients aged > 60 years, whereas vertebrobasilar artery developmental anomalies occurred with similar frequency in patients aged < 60 years and > 60 years. Patients with infarction of the brainstem or cerebellum were more likely to have vertebral artery stenosis or occlusion, basilar artery stenosis or occlusion, vertebral artery dominance or tortuosity, and basilar artery tortuosity, and patients with infarction of the thalamus, medial temporal, or occipital lobes were more likely to have stenosis or occlusion of the vertebral or basilar arteries. Vertebrobasilar artery tortuosity, vertebral artery dominance (hypoplasia), and congenital variations of the vertebrobasilar system may lead to posterior circulation infarction at different locations in different age groups.Daopei Zhang Shuling Zhang Hongtao Zhang Yuming Xu 2012Neural Regeneration Research2012,7,32:5
2ClC-3 chloride channel in hippocampal neuronal apoptosis显示文摘Over-production of nitric oxide is pathogenic for neuronal apoptosis around the ischemic area following ischemic brain injury.In this study,an apoptotic model in rat hippocampal neurons was established by 0.5 mmol/L 3-morpholinosyndnomine(SIN-1),a nitric oxide donor.The models were then cultured with 0.1 mmol/L of 4,4'-diisothiocyanostilbene-2,2'-disulfonic acid(DIDS;the chloride channel blocker) for 18 hours.Neuronal survival was detected using the 3-(4,5-dimethylthiazol- 2-yl)-2,5-diphenyltetrazolium bromide(MTT) assay,and apoptosis was assayed by Hoechst 33342-labeled neuronal DNA fluorescence staining.Western blot analysis and immunochemiluminescence staining were applied to determine the changes of activated caspase-3 and CIC-3 channel proteins.Real-time PCR was used to detect the mRNA expression of CIC-3.The results showed that SIN-1 reduced the neuronal survival rate,induced neuronal apoptosis,and promoted ClC-3 chloride channel protein and mRNA expression in the apoptotic neurons.DIDS reversed the effect of SIN-1.Our findings indicate that the increased activities of the ClC-3 chloride channel may be involved in hippocampal neuronal apoptosis induced by nitric oxide.Lijuan Xu Shuling Zhang Hongling Fan Zhichao Zhong Xi Li Xiaoxiao Jin Quanzhong Chang 2013Neural Regeneration Research2013,8,32:3
3Ecological Offsetting in China's Coastal Wetlands: Existing Challenges and Strategies for Future Improvement显示文摘Land-use changes in coastal wetlands have led to a worldwide degradation of marine coastal ecosystems and a loss of the ecological services they provide. Ecological offsetting is a popular strategy and an effective mitigation measure for ecosystems that have been degraded, damaged, or destroyed and is critical for habitats where natural recovery is hindered. However, the current understanding of the theory and practice of ecological offsetting for coastal wetlands is extremely limited in many developing countries. We conducted a review of ecological offsetting for coastal wetlands projects and studies in China in 1979–2017 to explore the application and limitations of ecological offsetting theory. It was found that China's coastal ecological offsetting regime has recently entered a rapidly developing stage, with an increasing number of different types of offsetting projects conducted, but theoretical research lags behind practical applications. Considerable governmental, social, technological and ethical challenges remain to resolve. Coastal ecological offsetting schemes have been inconsistent in meeting conservation objectives or preventing net losses because of the challenges of ensuring they are fully consistent in practice(mainly in-kind offsets) and theory(mainly out-of-kind offsets). Ecological offsetting projects were primarily implemented by government, developers, and non-profit organizations. The available funding of coastal ecological offsetting projects is insufficient, which makes ecological offsetting a risky operation. Therefore, we propose strategies for improvement that integrate the consideration of theoretical and practical challenges in the offsetting process, while providing a scientific basis and directional guidance for the future practice of biodiversity conservation and environmental management.YU Shuling CUI Baoshan XIE Chengjie MA Xu MAN Ying NING Zhonghua 2019Chinese Geographical Science2019,29,2:3
4Effects of minocycline on learning and memory of mice following ischemic-hypoxic cerebral injuries显示文摘An ischemic-hypoxic animal model was established using right common carotid artery occlusions and inhalation of low concentrations of oxygen in mice. At 10 days after the ischemic-hypoxic injuries, saline-treated mice exhibited significantly prolonged escape latencies in water-maze tests and significantly shorter memory latencies and more mistakes in step-down tests. In contrast, mice treated with 5 mg/kg minocycline exhibited significant reversals of each of these effects compared with the saline-treated control mice. Moreover, we found that minocycline can relieve brain water content and morphological changes in mice following ischemic-hypoxic cerebral injuries. Accordingly, our findings indicate that minocycline provides some protections against the deleterious effects of these injuries in mice.Hongling Fan Yuanyin Zheng Lijuan Xu Zhichao Zhong Shining Cai Shuling Zhang Quanzhong Chang 2012Neural Regeneration Research2012,7,2:2
5Shotgun lipidomic analysis of simple lipids in rapeseed oil by electrospray ionization tandem mass spectrometry显示文摘Rapeseed is widely grown in China as an important oil crop. In this study, Shotgun lipidomic methodology based on tandem mass spectrometry but without liquid chromatography was established for simple lipids analysis such as mono-, di-and triacylglycerols(MAGs, DAGs and TAGs) and the derivatives such as free fatty acids(FFAs). Six varieties of rapeseeds belonging to 3 types(B. juncea, B. campestris and B. oleracea) from different areas of China were investigated, with 59 TAG species, 10 DAG species, 5 MAG species and 6 FFA species identified. It was found that erucic acid was mainly present in the form of TAG 62:4(22:1/18:2/22:1), TAG 62:3(22:1/18:1/22:1), and TAG 62:5(22:1/18:3/22:1) in high erucic acid rapeseed oils, while oleic acid was mainly present in the form of TAG 54:2(18:0/18:1/18:1), and TAG 54:4(18:1/18:2/18:1) in high oleic acid rapeseed oils. It was difficult for DAG, MAG and FFA quantification due to their low content with high background content of TAGs. Results showed that the main differences in lipids were not derived from the types of rapeseed, but directly related to varieties.Xin Lv Fang Wei Shuling Xu Ya Xie Bangfu Wu Zongyuan Wu Xuyan Dong Hong Chen 2018Oil Crop Science2018,3,4:2
6Chloride channel blocker 4,4-diisothiocyanatostilbene-2,2'-disulfonic acid inhibits nitric oxide-induced apoptosis in cultured rat hippocampal neurons显示文摘Apoptosis in cultured rat hippocampal neurons was induced using the nitric oxide donor 3-morpholinosydnonimine, and cells were treated with the chloride channel blocker, 4,4-diisothiocyanatostilbene-2,2'-disulfonic acid. Results showed that the survival rate of neurons was significantly increased after treatment with 4,4-diisothiocyanatostilbene-2,2'-disulfonic acid, and the rate of apoptosis decreased. In addition, the expression of the apoptosis-related proteins poly(adenosine diphosphate-ribose)polymerase-1 and apoptosis-inducing factor were significantly reduced. Our experimental findings indicate that the chloride channel blocker 4,4- diisothiocyanatostilbene-2,2'-disulfonic acid can antagonize apoptotic cell death of hippocampal neurons by inhibiting the expression of the apoptosis-related proteins poly(adenosine diphosphate-ribose)polymerase-1 and apoptosis-inducing factor.Jinbao Yin Lijuan Xu Shuling Zhang Yuanyin Zheng Zhichao Zhong Hongling Fan XiLi Quanzhong Chang 2013Neural Regeneration Research2013,8,2:2

9Facet-dependent electrochemiluminescence spectrum of nanostructured ZnO显示文摘A facet-dependent electrochemiluminescence (ECL) behavior was found for nanostructured ZnO with different dominant exposing planes.The ECL spectrum of nanostructured ZnO was recorded by the emission scan mode with a fluorescence spectrometer and applied to investigate the difference of surface state for different crystal planes.Electronic structure calculations based on density functional theory were used to study the effect of crystal plane on the band structure and density of states.It revealed that the ECL emission was originated primarily from the recombination of electrons from Zn 4s and the hole from O 2p,which could be utilized to study the physical and chemical properties of surface structures of as-prepared nanostructured ZnO.A physical model was suggested to elucidate the differences of ECL spectra.A concept was proposed that the energy released as photons during ECL process of nanocrystalline semiconductor materials will be correlated with the energy level of active sites located at different crystal planes.WANG Lei YUE QiaoLi LI HaiBo XU ShuLing GUO LianShun ZHANG XianXi WANG HuaiSheng GAO XueXi WANG WenJun LIU JiFeng LIU Peng 2013Science China Chemistry2013,56,1:2
10Classification of facial nerve aberration in congenital malformation of middle ear:Implications for surgery of hearing restoration显示文摘Objectives: Facial nerve aberration is the most troublesome situation in congenital malformations of middle ear.The aim of our study is to investigate its imaging and clinical features as well as relevant choice of surgical techniques for hearing improvement.Methods: A retrospective study involving review of clinical data of 227 patients(256 ears) with congenital middle ear anomaly was undertaken, including preoperative computed tomography(CT) data, surgical records and videos.Results: Aberration involving intratemporal facial nerve was found in 82/256 ears(32.03%) with congenital middle ear anomaly. The most common forms of aberration included overhanging over the oval window(50/82 ears, 60.98%), bifurcation(3/82 ears, 3.66%) and transverse over the promontory(3/82 ears, 3.66%), counting for 68.29%(56/82) of the cases with facial nerve aberration. Concomitant stapes malformation was found in 76/82 ears(92.68%) and atresia or stenosis of the oval window in 27/82 ears(32.93%). In 9/82 ears(10.98%) both stapes and oval window was absent. Elective surgeries for the purpose of hearing improvement included stapodotomy + piston implantation, labyrinthotomy, labyrinthotomy + total ossicular replacement prosthesis(TORP) implantation and Vibrant Soundbridge(VSB) implantation.Conclusion: The majority of facial nerve aberration in congenital malformation of middle ear involves displacement of facial nerve, in addition to concomitant malformations of the stapes and/or oval window, which may influence the choice of surgery for hearing improvement. VSB implantation may be considered as a useful option.Jin Hao Liping Xu Shuling Li Xinxing Fu Shouqin Zhao 2018Journal of Otology2018,13,4:1

14LIFU-responsive nanomedicine enables acoustic droplet vaporization-induced apoptosis of macrophages for stabilizing vulnerable atherosclerotic plaques显示文摘Due to the high risk of tearing and rupture,vulnerable atherosclerotic plaques would induce serious cardiovascular and cerebrovascular diseases.Despite the available clinical methods can evaluate the vulnerability of plaques and specifically treat vulnerable plaques before a cardiovascular event,but the efficiency is still low and undesirable.Herein,we rationally design and engineer the low-intensity focused ultrasound(LIFU)-responsive FPD@CD nanomedicine for the highly efficient treatment of vulnerable plaques by facilely loading phase transition agent perfluorohexane(PFH)into biocompatible PLGA-PEG-PLGA nanoparticles(PPP NPs)and then attaching dextran sulphate(DS)onto the surface of PPP NPs for targeting delivery.DS,as a typical macrophages-targeted molecule,can achieve the precise vaporization of NPs and subsequently controllable apoptosis of RAW 264.7 macrophages as induced by acoustic droplet vaporization(ADV)effect.In addition,the introduction of DiR and Fe3O4 endows nanomedicine with near-infrared fluorescence(NIRF)and magnetic resonance(MR)imaging capabilities.The engineered FPD@CD nanomedicine that uses macrophages as therapeutic targets achieve the conspicuous therapeutic effect of shrinking vulnerable plaques based on in vivo and in vitro evaluation outcomes.A reduction of 49.4%of vascular stenosis degree in gross pathology specimens were achieved throughout the treatment period.This specific,efficient and biosafe treatment modality potentiates the biomedical application in patients with cardiovascular and cerebrovascular diseases based on the relief of the plaque rupture concerns.Jingxin Hou Jun Zhou Meiqi Chang Guangcheng Bao Jie Xu Man Ye Yixin Zhong Shuling Liu Junrui Wang Wei Zhang Haitao Ran Zhigang Wang Yu Chen Dajing Guo 2022Bioactive Materials2022,7,10:1
15Effects of calcium channel on 3-morpholinosydnonimine-induced rat hippocampal neuronal apoptosis显示文摘Previous studies have demonstrated that increased chloride channel activity plays a role in nitric oxide-induced neuronal apoptosis in the rat hippocampus. The present study investigated the effects of the broad-spectrum calcium channel blocker CdCl2 on survival rate, percentage of apoptosis, and morphological changes in hippocampal neurons cultured in vitro, as well as the effects of calcium channels on neuronal apoptosis. The chloride channel blockers 4-acetamido-4'-isothiocyanatostilbene-2, 2'-disulfonic acid (SITS) or 4, 4'-diisothiocyanostilbene-2, 2'-disulfonic acid (DIDS) increased the survival rate of 3-morpholinosydnonimine (SIN-1)-treated neurons and suppressed SIN-1-induced neuronal apoptosis. The calcium channel blocker CdCl2 did not increase the survival rate of neurons and did not affect SIN-1-induced apoptosis or SITS- or DIDS-suppressed neuronal apoptosis. Results demonstrated that calcium channels did not significantly affect neuronal apoptosis.Quanzhong Chang Shuling Zhang Yuanyin Zheng Lijuan Xu Jinbao Yin Shining Cai 2011Neural Regeneration Research2011,6,5:1
16Neoadjuvant chemotherapy with pingyangmycin can inhibit the amplification and metastasis of laryngeal squamous cell carcinoma显示文摘Objective:To evaluate the short-term effects of neoadjuvant chemotherapy with pingyangmycin(PYM)in the treat-ment of laryngeal squamous cell carcinoma.Methods:24 cases of laryngeal squamous cell carcinoma were treated with PYM before the operation,and the surgeries were undergone within one week after neoadjuvant chemotherapy.PCNA,p53,Bcl-2 and CD44v6 were detected in the specimens of tumor,retreated tumor and normal tissue using immunohistochemical methods.Results:Apoptosis could be detected more often in specimens with tumor and retreated tumor after chemotherapy than that before.The expression of PCNA,p53,Bcl-2 and CD44v6 in tumor tissue after neoadjuvant chemotherapy with PYM was weaker than that before the chemotherapy.There was significant difference in the positive ratio of PCNA,p53,Bcl-2 and CD44v6 be-tween retreated tumor and tumor.Conclusion:After neoadjuvant chemotherapy with PYM,a large number of tumor cells died.The amplification and metastasis of tumor were suppressed by neoadjuvant chemotherapy with PYM.Xiaolong Li Ming Gao Haifeng Yu Benyi Xu Zhengjin Ge Yang Yu Songfeng Wei Shuling Li 2006The Chinese-German Journal of Clinical Oncology2006,5,6:1

18Synergistic effect of F and triggered oxygen vacancies over F-TiO_(2) on enhancing NO ozonation显示文摘Oxidation-absorption technology is a key step for NOxremoval from low-temperature gas.Under the condition of low O_(3)concentration(O_(3)/NO molar ratio = 0.6), F-TiO_(2)(F-TiO_(2)), which is cheap and environmentally friendly, has been prepared as ozonation catalysts for NO oxidation. Catalytic activity tests performed at 120℃showed that the NO oxidation efficiency of F-TiO_(2)samples was higher than that of TiO_(2)(about 43.7%), and the NO oxidation efficiency of F-TiO_(2)-0.15 was the highest, which was 65.3%. Combined with physicochemical characteristics of catalysts and the analysis of active species, it was found that there was a synergistic effect between F sites and oxygen vacancies on F-TiO_(2), which could accelerate the transformation of monomolecular O_(3)into multi-molecule singlet oxygen(1O_(2)), thus promoting the selective oxidation of NO to NO_(2). The oxidation reaction of NO on F-TiO_(2)-0.15 follows the Eley-Rideal mechanism, that is, gaseous NO reacts with adsorbed O_(3)and finally form NO_(2).Lina Guo Xu Zhang Fanyu Meng Jing Yuan Yiqing Zeng Chenyang Han Yong Jia Mingyan Gu Shule Zhang Qin Zhong 2023Journal of Environmental Sciences2023,,3:0
19Importance of quality control in lipidomics profiling based on mass spectrometry显示文摘As a current analytical instrument for lipidomics profiling with high sensitivity, selectivity, and throughput, mass spectrometry (MS) has been widely used in the field of clinical medicine, nutrition, bromatology, botany and etc. During the routine use of shotgun- MS and high performance liquid chromatography-MS (HPLC-MS) in lipid analysis, an important problem to be solved is the defective repeatability and stability resulting from signal attenuation or drifts in LC-peak shape and retention time of MS platform. To remove or minimize the influence, extensively accepted and applied QC (quality control) samples must be performed. In this review, we emphasize the importance of the application of QC samples, which could 1) provide the ability to equilibrate the analytical platform at the beginning; 2) act as a quality assurance (QA) procedure during the analytical process; 3) perform signal correction in the data handling with the purpose of reducing analytical variation and improving the precision of quantitative analysis; 4) the data between different laboratories can be compared through the incorporation of particular QC samples-Standard Reference Material (SRM) 1950. In addition, we display 4 types and requirements of QC samples during quality control in lipidomics profiling. Lipidomics profiling based on MS strongly requires commonly accepted guidelines for quality control to perform routine, large-scale researches, so as to integrate data from different scientists for more information.Ya Xie Huifang Ma Fang Wei Xin Lyu Zongyuan Wu Bangfu Wu Shuling Xu Xuyan Dong Hong Chen Fenghong Huang 2017Oil Crop Science2017,2,4:0
20Investigation and Analysis of the Current Situation of Online Drug Sellers显示文摘Objective To provide reference for the relevant departments to train and manage online drug sellers.Methods A questionnaire was conducted among 124 grass-roots drug sellers from 13 online drug sales enterprises,including Tmall Medical Center and JD Home Health Channel and 265 teachers and students from 33 pharmaceutical colleges and universities.The problems were analyzed in this paper and some specific suggestions were made.Results and Conclusion 389 questionnaires were sent out and 371 effective questionnaires were recovered.The effective recovery rate was 95.37%.The universities surveyed mainly recruited undergraduates,accounting for 66.7%of the total.Most of the employees in the online drug sales enterprises surveyed graduated from secondary school or universities,accounting for 91.9%.The number of graduates surveyed who were willing to work in the online drug sales enterprises was low,accounting for only 8.67%.Besides,it was difficult for online drug sellers to be promoted,71.7%of the respondents had no promotion opportunities.In view of the main problems such as the low professional quality of online drug sellers,their low willingness to engage in online drug sales,and few promotion opportunities,it is suggested the reform of licensed pharmacists should be deepened to improve the number and quality of online drug sellers.Meanwhile,we should learn the advanced experience from developed countries.In addition,the income and welfare of the online drug sellers should be improved.Lastly,a unified management platform must be set up for online drug sellers by technical means.Xu Guangwei Wang Shuling 2021Asian Journal of Social Pharmacy2021,16,2:0
