Spectroscopic study on the interaction between[Hg(SCN)_4]^(2-) and hemoglobin

Chinese Chemical Letters 2012年第11期23卷 1283-1286页

The interaction between [Hg（SCN）4]^2- and hemoglobin （Hb） under conditions that simulate a physiological environment was investigated by UV-vis spectroscopy, fluorescence spectroscopy, resonance Rayleigh scattering （RRS） spectroscopy and circular dichroism （CD） spectroscopy. The results obtained from the change of UV-vis and CD spectra, the quenching of Hb fluorescence and the enhancement of RRS intensity proved that a 10：1 type complex was formed between [Hg（SCN）4]^2- and Hb. The possible mechanism suggested for the interaction was that ten Hg（SCN）4]^2- anions entered the four subunits of a Hb molecule to react with some residues to form an adduct by coordination and electrostatic forces. The coordination of [Hg（SCN）4]^2- with Trp was the major cause of the fluorescence quenching of Hb.

作者： fu-Min Xue Ming-Hui liang Zhen-Hua Wang ling-Yu Luan fu-Wei li Yan Cheng Guang-Sheng shao Shandong Provincial Analysis and Test Center ShanDong Academy of Science National Center for Nanosicence and Technology China Banknote Ink Company

Long-wavelength-sensitized luminescent materials are desired for bio-detection. In this paper, we prepared a new kind of luminescent europium nanoparticles by a co-precipitation-condensation method. The luminescent europium complex Eu（tta）*** （tta = thenoyltrifluoroacetonate; bpt = 2-（N,N- di-ethylanilin-4-yl）-4,6-bis（pyrazol-l-yl）-l,3,5-triazine） was used as the active material, being encapsulated in the nanoparticles formed from 1H, 1H, 2H, 2H-perfluorooctyltrimethoxysilane （PFOTS） and poly（styrene-co-methyl methacrylate） [P（ST-co-MMA）]. The prepared nanoparticles not only can be well dispersed in water but also were of high photostability. Importantly, the nanoparticles displayed maximal excitation wavelength at 425 nm as well as an extended excitation wavelength up to 480 nm and a quantum yield for Eu3＋ luminescence of 0.22 （λex= 425 nm, room temperature）.

作者： Bao Hai shao Xiu Zhu XU Jian De LU li ZOU Xiao Yun fu Department of Chemistry Zhejiang UniversityHangzhou 310027

The influence of different alcohol modifiers in mobile phase on the chiral separation of 4-methoxyl flavanone, 5-methoxyl flavanone and 6-methoxyl flavanone on cellulose tris (3, 5-dimethylphenylcarbamate) (CDMPC) column was studied and the chiral recognition mechanism was discussed. Using hexane-tert-butanol (1.31 mol L-1) as the mobile phase, those three methoxyl flavanones were excellently separated on CDMPC chiral column.

Bilateral liver resection for bilateral intrahepatic stones

引用

World Journal of Gastroenterology 2009年第29期15卷 3660-3663页

作者： shao-Qiang li li-Jian liang Yun-Peng Hua Bao-Gang Peng Dong Chen Shun-Jun fu Department of Hepatobiliary Surgery the First Affiliated Hospital Sun Yat-sen UniversityGuangzhou 510080 Guangdong Province China

AIM: To evaluate the shortand long-term outcomes of bilateral liver resection for bilateral intrahepatic stones. METHODS: We reviewed retrospectively 101 consecutive patients with bilateral intrahepatic stones who underwent bilateral liver resection in the past 10 years. The shortand long-term outcomes of the patients were analyzed. The Cox proportional hazards model was used to identify the risk factors related to stone recurrence. RESULTS: There was no surgical mortality in this group of patients. The surgical morbidity was 28.7%. Stone clearance rate after hepatectomy was 84.2% and final clearance rate was 95.0% following postoperative choledochoscopic lithotripsy. The stone recurrence rate was 7.9% and the occurrence of postoperative cholangitis was 6.5% in a median follow-up period of 54 mo. The Cox proportional hazards model indicated that liver resection range, less than the range of stone distribution (P = 0.015, OR = 2.152) was an independent risk factor linked to stone recurrence. CONCLUSION: Bilateral liver resection is safe and its shortand long-term outcomes are satisfactory for bilateral intrahepatic stones.
