Qualitative and Quantitative Evaluation of Chemical Constituents from Shuanghuanglian Injection Using Nuclear Magnetic Resonance Spectroscopy.

By employing nuclear magnetic resonance (NMR), we implemented a chemical research on Shuanghuanglian injection (SHLI) and identified 17 components, including eight primary metabolites and nine secondary metabolites. Guided by the approach of network pharmacology, the potential activities were briefly predicted for seven primary metabolites except for formic acid, such as anti-inflammation, antioxidation, and cardiovascular protection. The focused primary metabolites were quantified by a proton nuclear magnetic resonance (H-NMR) method, which was verified with good linearity and satisfactory precision, repeatability, stability, and accuracy (except for -inositol with mean recovery at 135.

Application effect of tirofiban on percutaneous coronary intervention in patients with acute coronary syndrome and its postoperative effect on C-X-C motif chemokine ligand 16 level and myocardial perfusion.

This study aimed to investigate the application effect of tirofiban on percutaneous coronary intervention (PCI) in patients with acute coronary syndrome (ACS) and its postoperative effect on C-X-C motif chemokine ligand 16 (CXCL16) level and myocardial perfusion. A total of 50 cases of patients diagnosed with acute coronary syndrome and treated in Sunshine Union Hospital (Weifang, China) were included in group A and 30 cases of healthy subjects underwent physical examination in our hospital during the same period were enrolled in group B. Tirofiban was used in group A patients during PCI.

[Study on different proportion formulas of activating blood circulation by FTIR].

Fourier transform spectroscopy (FTIR) and two-dimensional correlation spectroscopy were used to analyze different compatibility forms of sargentgloryvine stem, radix paeoniae rubra and cortex moutan in order to study the FTIR spectra of different proportion formulas. The results indicate that different proportion formulas have distinct change regularity in FTIR spectra, second derivative spectra and synchronous 2D. Key components of sargentgloryvine stem's characteristic absorption band are 1 610, 1 518 and 1 446 cm(-1) which are characteristic absorption band of aromatic material, and in the original formula, that shows stronger peak than others, suggesting that original formula can make the best of composition of drug action.

[Analysis and comparison of daxueteng and their extracts by FTIR].

The present study is to compare and analyze Sargentodora cuneata (oliv) Rehd. etwils herbs, the aqueous, anthraquinone extracts and residue in Jiang Xi and An Hui quickly and undamagedly by Fourier transform infrared spectroscopy(FTIR) and two-dimensional correlation spectroscopy. In the spectra of DaXueTeng, there are two strong peak areas at about 1400-1620 cm(-1) and 1000-1200 cm(-1), and it was concluded that DaXueTeng contains much glycoside and anthraquinone.

[Qualitative and quantitative analysis of Shuanghuanglian fenzhenji by FTIR].

Qualitative and quantitative analysis of Shuanghuanglian fenzhenji was studied in the present paper by FTIR. The fingerprint characteristics of main components in the injections were assigned and can be used as the criterion in the qualitative quality control. Calibration models by PLS algorithm were built to get the quantitative information of baicalin and chlorogenic acid in the injection samples.
