The land subsidence poses a nonnegligible threat to production and life, especially in dredger fill area. The essence of land subsidence is soil consolidation. Better evaluation of the degree of soil consolidation presents significant progress for predicting land subsidence. In this study, SBAS-InSAR was conducted to Chenjia town, the typical dredger fill area in Chongming East Shoal, Shanghai. SAR data and precise Orbit data were collected from the ESA satellite Sentinel-1 in recent 2 years with approximately one month intervals. the relationship curve of cumulative subsidence with time is obtained after processing. On this basis, the final settlement and soil consolidation can be estimated by applying the method proposed by Professor Huang Wenxi of China. The results show that: The subsidence rate is faster than 20 mm/a; The estimated final settlement is 26.6-52.9 mm, and the corresponding consolidation degree is 54.6 % on average; Soil mass has not yet been fully consolidated and it still takes a long time to achieve stability. In conclusion, the method proposed in this study can provide a clearer understanding of the consolidation degree, and a new reference for the evaluation and prevention of land subsidence. Future research will focus on longer monitoring time to enrich and improve the method.

A simple, sensitive and reproducible high-performance liquid chromatography (HPLC) method has been validated for determining concentrations of glutamate, glycine, and alanine in human plasma. Proteins in plasma were precipitated with perchloric acid, followed by derivatization with 6-aminoquinolyl-N-hydroxysuccinimidyl carbamate (AQC). Simultaneous analysis of glutamate, glycine, and alanine is achieved using reversed-phase HPLC conditions and ultraviolet detection. Excellent linearity was observed for these three amino acids over their concentration ranges with correlation coefficients (r)>0.999. The intra- and inter-day precision were below 10%. This method utilizes quality control samples and demonstrates excellent plasma recovery and accuracy. The developed method has been successfully applied to measure plasma glutamate, glycine, and alanine in twenty volunteers.
Sensitive Optical Probe for Hydrogen Peroxide Using Carbon Quantum Dots Synthesized by Glutathione
Qing Huang,Huawen Zhao 성균관대학교(자연과학캠퍼스) 성균나노과학기술원 2019 NANO Vol.14 No.7
Herein, we present the one-pot synthesis of carbon quantum dots (CQDs) using glutathione and used for the optical detection of hydrogen peroxide (H2O2). Unlike as reported in other literatures, the detection of H2O2 is free of using any additional chromogenic agents or metal ions. The CQDs are synthesized using glutathione by one-pot hydrothermal at 180 ℃. The as-prepared CQDs exhibit good fluorescence response toward H2O2 without involving extra chromogenic substances. The addition of 300 μM H2O2 to CQDs induces the quenching of fluorescence, besides the yellow becomes colorless. The decrease in the fluorescence is attributed to the polymeric structure of CQDs disbanded by H2O2. In addition, the practical application of the present method was verified by determining H2O2 in human urine samples.

A photonic crystal slab that was constructed as a 2D hexagonal photonic crystal with a finite depth and was etched into an ion-implanted LiNbO_3 waveguide was simulated by using the finitedifference time-domain (FDTD) method. Both the ΓK-oriented and ΓM-oriented propagations were simulated with the fundamental TE mode of the LiNbO_3 waveguide as the incident beam. Despite the weak vertical confinement, the transmittance spectra show that they both have quite deep stop gaps. These gaps show a good overlap. At wavelengths within the overlap region, both the line defects that we created in the ΓK and the ΓM directions worked very well as channel waveguides.

Background: In clinics, Ziwuliuzhu acupuncture is widely considered an effective method of treating insomnia; however, there is currently limited information available regarding its possible mechanisms. Although the method of Ziwuliuzhu acupuncture possesses a unique rhythmic pattern. Objectives: In this study, we have creatively combined the traditional Chinese medicine of Ziwuliuzhu with a modern biological rhythm to investigate the internal mechanism of insomnia. Methods: Pathological tissue from the hypothalamus was analyzed using hematoxylin– eosin staining. The level of TNF (tumor necrosis factor)-α in the SCN (suprachiasmatic nucleus) area of the hypothalamus was detected in situ using the TUNEL fluorescence staining assay. The concentration of hypothalamic melatonin was detected using the enzyme-linked immunosorbent assay (ELISA). The mRNA expression of Clock and Bmal1 was measured using RT-qPCR. Results: In the Ziwuliuzhu acupuncture groups, the structural damage in the hypothalamic neurons was alleviated compared to the model group and the expression of inflammatory factors was reduced. The mRNA expression levels of Clock and Bmal1 were significantly increased (p < 0.05). The concentration of melatonin was significantly increased (p < 0.001). Although there were no significant differences between the treatment groups (diazepam group, Nazi group, Najia group, and routine group) (p > 0.05). Conclusion: Ziwuliuzhu acupuncture alleviated neuronal damage and modulated the inflammatory reaction in the hypothalamus of rats with insomnia. Moreover, Ziwuliuzhu acupuncture increased the expression levels of Clock and Bmal1 mRNA, and MT content. This study has potentially highlighted one of

( Qing Wang ),( Qing-bo Yu ),( Tian-liang Yang ),( Xin-lei Huang ),( Xue-xin Yan ) 대한지질공학회 2019 대한지질공학회 학술발표회논문집 Vol.2019 No.2
Structural property of soil is a new concept studied in science and study of this issue is a new problem, which involves soil mechanical effect, mechanical variability, and engineering design. Soil such as saline soil, red soil, loess, Xiashu loess, soft soil, or solidified dredger fill, which had been studied in previous research by our research group, has high pre-consolidation pressure (Pc) and high over-consolidation ratio (OCR). Considering the needs of intensity determination in engineering design, soil structure force, structural strength and other issues of structural Soils were studied in this paper. By analyzing experimental data, affecting factors of pre-consolidation pressure (Pc) was discussed. A new cognition about pre-consolidation pressure (Pc), determination method of structural strength, and genetic mechanism of structural force were proposed in this paper. Soil mass structural behavior and the mechanical effect can be one of the important fields of soil structural quantitative research.

Huang, Chang-Xin,Zhu, Ying,Duan, Guang-Liang,Yao, Ji-Fen,Li, Zhao-Yang,Li, Da,Wang, Qing-Qing Asian Pacific Journal of Cancer Prevention 2013 Asian Pacific journal of cancer prevention Vol.14 No.8
Objective: To use microarray chip technology for screening of stem cell radiation related miRNAs in laryngeal squamous cell carcinoma; study and explore the relationship of miRNAs with radiosensitivity of laryngeal squamous cells. Method: After conventional culture and amplification of the laryngeal squamous carcinoma cell line Hep-2, CD 133+ cells were screened out with combination of isolated culture of stem cell microspheres and FACS for preparation of laryngeal cancer stem cells. After radiation treatment, miRNAs of laryngeal squamous carcinoma stem cells before and after radiation were enriched and purified. After microarray hybridization with mammalian miRNA and scanning of fluorescence signal, the miRNAs of laryngeal squamous carcinoma stem cells before and after radiation was subject to differential screening and clustering analysis. Real-time quantitative RT-PCR was used to verify part of the differentially expressed miRNAs. Results: 70 miRNAs related to laryngeal cancer stem cell radiation with 2-fold difference in expression were screened out, in which 62 were down-regulated and 8 were up-regulated. Fluorescent quantitative RT-PCR results were consistent with miRNAs chip results. Conclusion: Some miRNAs may be involved in self-regulation with laryngeal squamous carcinoma stem cell radiation.
