        Anesthetic Management and Outcomes of Endovascular Treatment of Basilar Artery Occlusion: Results From the ATTENTION Registry

        Tao Chunrong,Yuan Guangxiong,Xu Pengfei,Wang Hao,Zhou Peiyang,Yi Tingyu,Li Kai,Cui Tao,Gao Jun,Li Rui,Sun Jun,Zhang Chao,Wang Li,Liu Tianlong,Song Jianlong,Yin Yamei,Nguyen Thanh N.,Li Qing,Hu Wei 대한뇌졸중학회 2023 Journal of stroke Vol.25 No.3

        Background and Purpose To examine the clinical and safety outcomes after endovascular treatment (EVT) for acute basilar artery occlusion (BAO) with different anesthetic modalities. Methods This was a retrospective analysis using data from the Endovascular Treatment for Acute Basilar Artery Occlusion (ATTENTION) registry. Patients were divided into two groups defined by anesthetic modality performed during EVT: general anesthesia (GA) or non-general anesthesia (non-GA). The association between anesthetic management and clinical outcomes was evaluated in a propensity score matched (PSM) cohort and an inverse probability of treatment weighting (IPTW) cohort to adjust for imbalances between the two groups. Results Our analytic sample included 1,672 patients from 48 centers. The anesthetic modality was GA in 769 (46.0%) and non-GA in 903 (54.0%) patients. In our primary analysis with the PSM-based cohort, non-GA was comparable to GA concerning the primary outcome (adjusted common odds ratio [acOR], 1.01; 95% confidence interval [CI], 0.82 to 1.25; <i>P</i>=0.91). Mortality at 90 days was 38.4% in the GA group and 35.8% in the non-GA group (adjusted risk ratio, 0.95; 95% CI, 0.83 to 1.08; <i>P</i>=0.44). In our secondary analysis with the IPTW-based cohort, the anesthetic modality was significantly associated with the distribution of modified Rankin Scale at 90 days (acOR: 1.45 [95% CI: 1.20 to 1.75]). Conclusion In this nationally-representative observational study, acute ischemic stroke patients due to BAO undergoing EVT without GA had similar clinical and safety outcomes compared with patients treated with GA. These findings provide the basis for large-scale randomized controlled trials to test whether anesthetic management provides meaningful clinical effects for patients undergoing EVT.

        High‑speed growth of high‑quality polycrystalline diamond films by MPCVD

        Kai Chen,Tao Tao,Wenxiao Hu,Yucong Ye,Kaiwen Zheng,Jiandong Ye,Ting Zhi,Xiwei Wang,Bin Liu,Rong Zhang 한국탄소학회 2023 Carbon Letters Vol.33 No.7

        High-quality diamond films have attracted extensive attentions due to their excellent optical and electrical properties. However, several issues, such as random orientation, stress accumulation, and slow growth rate, severely limit its applications. In this paper, high-quality polycrystalline diamond films with highly ordered (100) orientation were prepared by microwave plasma chemical vapor deposition. The effects of growth parameters on the microstructure, quality and residual stress of diamond films were investigated. Experimental results indicate that relatively high temperature at low methane concentration will promote the formation of (100) oriented grains with a low compressive stress. Optimized growth parameters, a methane concentration of 2% along with a pressure of 250 Torr and temperature at 1050 ℃, were used to acquire high growth rate of 7.9 μm/h and narrow full width at half maximum of Raman peak of 5.5 cm? 1 revealing a high crystal quality. It demonstrates a promising method for rapid growth of high-quality polycrystalline diamond films with (100) orientation, which is vital for improving the diamond related applications at low cost.

        Preliminary Application of High-Definition CT Gemstone Spectral Imaging in Hand and Foot Tendons

        Kai Deng,Cheng-Qi Zhang,Wei Li,Jun-Jun Wang,Xin-Yi Wang,Tao Pang,Guang-Li Wang,Cheng Liu 대한영상의학회 2012 Korean Journal of Radiology Vol.13 No.6

        Objective: To assess the feasibility of visualizing hand and foot tendon anatomy and disorders by Gemstone Spectral Imaging (GSI) high-definition CT (HDCT). Materials and Methods: Thirty-five patients who suffered from hand or foot pain were scanned with GSI mode HDCT and MRI. Spectrum analysis was used to select the monochromatic images that provide the optimal contrast-to-noise ratio (CNR) for tendons. The image quality at the best selected monochromatic level and the conventional polychromatic images were compared. Tendon anatomy and disease were also analyzed at GSI and MRI. Results: The monochromatic images at about 65 keV (mean 65.09 ± 2.98) provided the optimal CNR for hand and foot tendons. The image quality at the optimal selected monochromatic level was superior to conventional polychromatic images (p = 0.005, p < 0.05). GSI was useful in visualizing hand and foot tendon anatomy and disorders. There were no statistical differences between GSI and MRI with regard to tendon thickening (χ2 = 0, p > 0.05), compression (χ2 = 0.5, p > 0.05), absence (χ2 = 0, p > 0.05) and rupture (χ2 = 0, p > 0.05). GSI was significantly less sensitive than MRI in displaying tendon adhesion (χ2 = 4.17, p < 0.05), degeneration (χ2 = 4.17, p < 0.05), and tendinous sheath disease (χ2 = 10.08, p < 0.05). Conclusion: GSI with monochromatic images at 65 keV displays clearly the most hand and foot tendon anatomy and disorders with image quality improved, as compared with conventional polychromatic images. It may be used solely or combined with MRI in clinical work, depending on individual patient disease condition.

        Overexpression of AtNHX1, a Vacuolar Na+/H+ Antiporter from Arabidopsis thalina, in Petunia hybrida Enhances Salt and Drought Tolerance

        Kai Xu,Ping Hong,Lijun Luo,Tao Xia 한국식물학회 2009 Journal of Plant Biology Vol.52 No.5

        PlantNa+/H+ antiporter plays a critical role in plant salt tolerance. In this study, AtNHX1, a vacuolar Na+ /H+ antiporter from Arabidopsis thalina, was introduced into Petunia hybrida using Agrobacterium-mediated methods. Polymerase chain reaction (PCR) and DNA gel blot analysis confirmed that AtNHX1 was successfully integrated into the P. hybrida genomes. Reverse transcription (RT)-PCR analysis indicated that AtNHX1 expressed highly in transgenic plants. It was found that the 35S::AtNHX1 transgenic P. hybrida plants showed much more resistant to high concentrations of NaCl and to water deprivation than the isogenic wild-type (WT) Petunia plants. The transgenic plants accumulated more Na+, K+, and proline in their leaf tissue than that of the WT Petunia plants and maintained high water contents and high ratio of K+/Na+. These results demonstrated that overexpression of the vacuolar Na+/H+ antiporter conferred both salt tolerance and drought tolerance to the transgenic Petunia plants.

        Design of an Input-Parallel Output-Parallel Multi-Module DC-DC Converter Using a Ring Communication Structure

        Tao Hu,Muhammad Mansoor Khan,Kai Xu,Lixin Zhou,Ahmad Rana 전력전자학회 2015 JOURNAL OF POWER ELECTRONICS Vol.15 No.4

        The design feasibility of a micro unidirectional DC transmission system based on an input-parallel output-parallel (IPOP) converter is analyzed in this paper. The system consists of two subsystems: an input-parallel output-series (IPOS) subsystem to step up the DC link voltage, and an input-series output-parallel (ISOP) subsystem to step down the output voltage. The two systems are connected through a transmission line. The challenge of the delay caused by the communication in the control system is addressed by introducing a ring communication structure, and its influence on the control system is analyzed to ensure the feasibility and required performance of the converter system under practical circumstances. Simulation and experiment results are presented to verify the effectiveness of the proposed design.

        Identification and Characterization of EDT1 Conferring Drought Tolerance in Rice

        Tao Wu,Mingxing Zhang,Hongjia Zhang,Kai Huang,Mojun Chen,Chen Chen,Xue Yang,Zhao Li,Haoyuan Chen,Zhiming Ma,Xunming Zhang,Wenzhu Jiang,Xinglin Du 한국식물학회 2019 Journal of Plant Biology Vol.62 No.1

        Basic Leucine Zipper (bZIP) transcription factors(TFs) play important roles in many processes, especially inabiotic stress response in plants. In this study, we characterizeda new gene EHANCED DROUGHT TOLERANCE 1 (EDT1),member of group E of bZIP transcription factor family inrice. The EDT1 protein contains one bZIP domain, oneputative nuclear localization signal (NLS) and six conservedphosphorylation sites. The expression of EDT1 is suppressedby several abiotic stresses, such as cold, droutht, and salt. Corresponding with expression patterns, several stress-associatedcis-acting elements were found in the EDT1 promoter. Theresults of subcellular localization and transactivation abilityanalyses indicated that EDT1 was localized in the nucleusand functioned as a nuclear protein, with its transactivationactivity primarily located in N-terminal. Transgenic riceoverexpressing EDT1 showed drought tolerance that hasbeen significantly improved. Real-time PCR analysis revealedthat some stress-related genes, such as OsbZIP12, SNAC1,OsLEA3, OsbZIP16, OsbZIP10 and OsABI2 were up-regulatedin EDT1 overexpression lines. These results indicate thatEDT1 plays a positive role in drought tolerance and providesvaluable targets for breeding drought-tolerant rice cultivars.

        Polishing Characteristics of MnO2 Polishing Slurry on the Si-face of SiC Wafer

        Tao Yin,Tosiro Doi,구로가와슈헤이,Zhao zhong Zhou,Kai ping Feng 한국정밀공학회 2018 International Journal of Precision Engineering and Vol.19 No.12

        To realize an efficient and high-quality chemical-mechanical polishing process for the surface of a SiC wafer, a new type of MnO2 slurry is developed employing the multi-valence and oxidation-reduction characteristics of MnO2 particles. This slurry is utilized to polish the Si-face of SiC wafers. In this paper, the influences of the polishing particle concentration and the pH of slurry on MRR are analyzed, the polishing performance of the MnO2 slurry is studied, and the polishing mechanism of the MnO2 slurry on the SiC wafer is determined. The polishing mechanism of the MnO2 slurry is verified by selecting commonly used additives, such as KMnO4, and the influence of the additive amount on the MRR is analyzed. Finally, the surface morphology of the material after polishing is observed with analytical instruments. The experimental results show that the MRR of the MnO2 slurry is highly dependent on the pH value of the slurry. The MnO2 particles tend to convert into MnO4 - ions in an alkaline environment, and the strong oxidizing property of MnO4 - ions greatly improves the polishing efficiency. As the MnO4 - ion concentration increases, the MRR can reach over 600 nm/ h, and an ultra-smooth surface with a surface.

      • Research Paper : Influences of long-term different types of fertilization on weed community biodiversity in rice paddy fields

        ( Kai Yuan Wan ),( Yong Tao ),( Ru Hai Li ),( Jun Feng Pan ),( Lei Lei Tang ),( Fang Chen ) 한국잡초학회 2012 Weed Biology and Management Vol.12 No.1

        In order to provide a scientific basis for developing integrated weed management strategies in rice paddy fields, this study investigated the influences of different types of fertilization on weed biodiversity. The experiment was conducted at Long-term-located Monitoring Station for Soil Fertility, Agricultural Science Academy, of Jiangxi Province, China. Five fertilization treatments were set: no fertilization (NOF), PK, NP, NK, and NPK. The results showed that the influence of different fertilization treatments on weed community traits followed the models PK > NOF > NK > NP > NPK for species richness, PK > NOF > NK > NP > NPK for species diversity, NPK > NP > NK > NOF > PK for community dominance, and PK > NOF > NK > NP > NPK for community evenness. Under NPK (i.e. balanced fertilization), the weed species diversity and richness and weed community evenness were the lowest. The principal component analysis showed that the weed community was divided into three groups: (i) NK and a part of NOF; (ii) NP and NPK; and (iii) PK and NOF. The correlation analysis indicated that the influence of each macro-element on the weed community followed the model N > P > K. The organic content in the paddy soil might have played an equally important role with the amount of available N in determining the weed community`s characteristics. Regarding the way by which N, P, and K influenced the weed community, the amount of available P and K mainly influenced the organic content, while the amount of available N influenced both the organic content and light transmittance within the canopy, thereby enhancing the capacity of rice to compete with weeds.
