| 1 | Gas chromatography-mass spectrometry analysis of essential oils from five parts of Chaihu(Radix Bupleuri Chinensis)显示文摘OBJECTIVE: To analyze the essential oils from flowers, leaves, stems, roots, and fruits of Chaihu(Radix Bupleuri Chinensis).METHODS: We extracted essential oils from different parts of Chaihu(Radix Bupleuri Chinensis) using a steam distillation method. The essential oils were analyzed by gas chromatography-mass spectrometry(GC-MS). Data were collected in full scan mode(m/z 60-600). Volatile components were identified based on their retention indices and by comparing their mass spectra with those in the National Institute of Standards and Technology 2005 database assisted by tandem mass spectrometry information. The relative content of each constituent wasdetermined by area normalization.RESULTS: We identified 111 components, of which12 were common to all 5 parts, 30 were found only in roots, 14 were found only in flowers, 6 were found only in leaves, 4 were found only in stems,and 17 were found only in fruits.CONCLUSION: Our results show that the stems,flowers, leaves, and fruits of Chaihu(Radix Bupleuri Chinensis)contain a high concentration of essential oils, and that the exact composition of the essential oils differs among the plant parts. To develop new medicines and make full use of the Chaihu(Radix Bupleuri Chinensis)resource, it is important to characterize the essential oils from different parts of the plant. In future research, it will be important to determine the pharmacological effects of the various components and the essential oil mixtures. | Jie Meng Xingfu Chen Wenyu Yang Jiuhua Song Yu Zhang Zhifei Li Xingwang Yang Zhanguo Yang | 2014 | Journal of Traditional Chinese Medicine2014，34，6： | 9 |
| 2 | Chaotic invariant sets of a delayed discrete neural network of two non-identical neurons显示文摘In this paper, we show that a delayed discrete Hopfield neural network of two nonidentical neurons with no self-connections can demonstrate chaotic behavior in a region away from the origin. To this end, we first transform the model, by a novel way, into an equivalent system which enjoys some nice properties. Then, we identify a chaotic invariant set for this system and show that the system within this set is topologically conjugate to the full shift map on two symbols. This confirms chaos in the sense of Devaney. Our main result is complementary to the results in Kaslik and Balint (2008) and Huang and Zou (2005), where it was shown that chaos may occur in neighborhoods of the origin for the same system. We also present some numeric simulations to demonstrate our theoretical results. | CHEN YuanLong HUANG Yu ZOU XingFu | 2013 | Science China Mathematics2013，56，9： | 6 |

| 4 | Effect of melt superheating treatment on the cast structure of K465 nickel-based superalloy显示文摘The cast structure of a K465 nickel-based superalloy with different temperatures of melt superheating treatment was studied. It is shown that melt superheating treatment plays a significant role in the grain size and carbide morphology. With increasing melt superheating temperature (below 2023 K),the grain size increases obviously and the carbide morphology is changed from a blocky to a script-like shape. However,when the melt superheating temperature is between 2023 K and 2123 K,the grain size decreases gradually,and the morphology of the MC carbide changes back to the blocky appearance. The content of W is also influenced by melt superheating treatment. | Pei, Zhongye Zhao, Minghan Tian, Yanwen Li, Juntao Chen, Xingfu Wu, Jiantao | 2009 | Rare Metals2009，28，2： | 5 |

| 7 | Rapid and highly effective bacteria-killing by polydopamine/IR780@MnO_2–Ti using near-infrared light显示文摘Bacterial infections are becoming a serious public health challenge because the abuse of antibiotics worldwide has caused bacterial resistance and the occurrence of superbugs. In this work, a new near-infrared(NIR) photoresponsive coating was constructed on Ti implant material, which was composed of MnO_2, IR780 photosensitizer and polydopamine(PDA). Under the irradiation of 808 nm NIR light, the component of MnO_2 in the coating exhibited high photothermal performance, and IR780 could be stimulated to generate ROS as a photosensitizer. The addition of PDA not only improved the cytocompatibility of the composite coating but also strengthened the light absorption ability of the system. Under the irradiation of 808 nm NIR light for 15 min, the composite coating killed 99.94% Staphylococcus aureus and 99.89% Escherichia coli on Ti plates. This rapid and highly effective bactericidal rate was ascribed to the synergistic effects of photothermal performance and photodynamic effect of the coatings excited by NIR light. Cell culture tests showed that PDA/IR780@MnO_2–Ti had good cytocompatibility due to the excellent biocompatibility of PDA and nanostructured surface. Therefore,this surface system will be a very promising plateform to safely and effectively kill bacteria on biomedical devices and implants in a short time. | Xingfu Teng Xiangmei Liu Zhenduo Cui Yufeng Zheng Da-fu Chen Zhaoyang Li Yanqin Liang Shengli Zhu Shuilin Wu | 2020 | Progress in Natural Science:Materials International2020，30，5： | 1 |
| 8 | Solitary Langerhans cell histiocytosis of frontal lobe: a case report and literature review显示文摘The brain parenchymal Langerhans cell histiocytosis(LCH) without systemic disease or lytic skull lesions is extremely rare. We report a 23-year-old male presenting with new onset 1 hour seizure with loss of consciousness 20 days prior to admission, and recurrent seizure 2 weeks later. Brain magnetic resonance imaging(MRI) showed an irregularly mass with enhancement involving the right frontal lobe. Microscopically, the lesion was characterized by sheets of Langerhans cells in addition to reactive inflammatory elements. Immunohistochemically, Langerhans cells were positive for Langerin, CD1a and S-100 protein. The patient received no chemotherapy or radiotherapy after surgery. After 24 months of follow-up, no recurrence or other systemic lesions were observed. Although there is no standard treatment for solitary cerebral LCH, the prognosis generally appears to be good. | Shanshan Cai Sheng Zhang Xueyong Liu Yuanxiang Lin Chunlin Wu Yupeng Chen Jianping Hu Xingfu Wang | 2014 | Chinese Journal of Cancer Research2014，26，2： | 1 |

| 17 | Epitaxial Lift-Off of Flexible GaN‑Based HEMT Arrays with Performances Optimization by the Piezotronic Effect显示文摘High-electron-mobility transistors(HEMTs)are a promising device in the field of radio frequency and wireless communication.However,to unlock the full potential of HEMTs,the fabrication of large-size flexible HEMTs is required.Herein,a large-sized(>2 cm^(2))of AlGaN/AlN/GaN heterostructure-based HEMTs were successfully stripped from sapphire substrate to a flexible polyethylene terephthalate substrate by an electrochemical lift-off technique.The piezotronic effect was then induced to optimize the electron transport performance by modulating/tuning the physical properties of two-dimensional electron gas(2DEG)and phonons.The saturation current of the flexible HEMT is enhanced by 3.15%under the 0.547%tensile condition,and the thermal degradation of the HEMT was also obviously suppressed under compressive straining.The corresponding electrical performance changes and energy diagrams systematically illustrate the intrinsic mechanism.This work not only provides in-depth understanding of the piezotronic effect in tuning 2DEG and phonon properties in GaN HEMTs,but also demonstrates a low-cost method to optimize its electronic and thermal properties. | Xin Chen Jianqi Dong Chenguang He Longfei He Zhitao Chen Shuti Li Kang Zhang Xingfu Wang Zhong Lin Wang | 2021 | Nano-Micro Letters2021，13，4： | 0 |
| 18 | Comparison of proliferation index between nestin-positive cells and glial fibrillary acidic protein-positive cells in human astrocytic tumors显示文摘Multivariate modeling has demonstrated that the proliferation index (PI) of tumor cells is one of the str ongest prognostic factors related to the survival of patients with astrocytic tumors.Studies have indicated that the glioma regenerative cells derived from nestin-positive (N+) cells after chemotherapy.Early removal of N+ cells can block the malignant progress of tumor.2 However,few studies compared the PI between N+ cells and glial fibrillary acidic protein (GFAP)-positive (GFAP+) cells in human astrocytic tumors.In the present study,we investigated the distribution and proliferation ofN+ cells and GFAP+ cells in human astrocytic tumors to clarify the role these cells play in the cytopathology of these tumors. | Yang Lijuan Wang Xingfu Chen Yupeng Zhang Sheng Zhen Shiming Lin Zhixiong | 2014 | Chinese Medical Journal2014，，2： | 0 |
