The study aims to identify the related substances in fasudil hydrochloride by hyphenated techniques. A WondaSil C18 (250 mm x 4.6 mm, 5 microm) column was used for the separation of the related substances with a mixture of methanol and ammonium acetate buffer solution as the mobile phase by gradient elution. The structures of the related substances were speculated by electrospray positive ionization LC-TOF/MS accurate ion mass and MS/MS determination and elucidation, and verified further through synthesis and spectroscopic analysis. Fasudil hydrochloride and the related substances were separated under the established HPLC condition. Three related substances in fasudil hydrochloride were characterized by hyphenated techniques. The hyphenated LC-MS method is useful for the identification of related substances in fasudil hydrochloride and the results obtained are valuable for its manufacturing process and quality control.

A sensitive and selective liquid chromatography–tandem mass spectrometric (LC ? MS/MS) method was established to determine 2-oxo-clopidogrel, a crucial intermediate metabolite in human plasma. A chromatographic separation was performed on a Sapphire C18 column following a liquid–liquid extraction sample preparation with methyl t-butyl ether. Detection was carried out on a triple quadrupole mass spectrometer operated in multiple reaction monitoring (MRM) with an electrospray ionization (ESI) mode. The method was validated in terms of specificity, accuracy, precision and limit of quantification. The calibration curves ranged from 0.50 to 50.0 ng/mL with good linearity. The stability was fully validated with addition of 1,4-dithio-DL-threitol (DTT) into the plasma sample prior to and in the preparation procedure. The validated method was proved to be suitable for use in pharmacokinetic study after single oral administration of 75 mg clopidogrel tablets in human subjects, which could make contribution to intensive study of the clinical drug–drug interactions of clopidogrel and individual treatment.

Objective To investigate the effects of phenylephrine and norepinephrine on tissue oxygen metabolism in elderly patients undergoing fluid restriction. Methods Eighty elderly patients who had underwent elective colorectal surgery were selected, with ASA of Ⅰ-Ⅱ grade. The patients were divided into restricted fluid administration combined with phenylephrine group (group Ⅰ) and restricted fluid administration combined with norepinephrine group (groupⅡ) by random digits table with 40 cases each. The compound recipe sodium lactate was given at a rate of 5 ml/(kg · h). Small dose of phenylephrine was infused intravenously at 0.1-0.3μg/(kg · min) simultaneously during the surgery in group Ⅰ, or norepinephrine 0.01-0.03 μg/(kg · min) in group Ⅱ. Mean arterial pressure (MAP) was maintained ≥ 65 mmHg (1 mmHg = 0.133 kPa). The intraoperative blood loss was replaced with the equal volume of 6% hydroxyethyl starch 130/0.4. The blood gas analysis, hemoglobin and so on were determined before the surgery (T0), 1 h after beginning of surgery (T1), 2 h after beginning of surgery (T2) and at the time of leaving operation room (T3). The complications were recorded. Results There were no statistical differences in MAP, central venous pressure (CVP), heart rate, lactic acid, arterial partial pressure of oxygen, central venous oxygen pressure, central venous blood oxygen saturation, oxygen uptake rate, hemoglobin, albumin, blood urea nitrogen, creatinine and incidence of complication between 2 groups (P>0.05). The T1-3 hemoglobin and arterial oxygen content (CaO2), T1 and T3 venous oxygen content (CcvO2) and T2 atrerial venous oxygen content differences (Da-cvO2) in groupⅠwere significantly higher than those in groupⅡ, hemoglobin:(103.8 ± 7.9) g/L vs. (110.8 ± 8.6) g/L, (101.7 ± 7.7) g/L vs. (107.3 ± 7.8) g/L and (101.6 ± 6.9) g/L vs. (106.8 ± 5.6) g/L; CaO2: (140.6 ± 9.7) mmol/L vs. (149.6 ± 10.5) mmol/L, (137.5 ± 9.3) mmol/L vs. (144.9 ± 10.2) mmol/L and (137.2 ± 9.2) mmol/L vs. (143.1 ± 8.9) mmol/L;CcvO2:(119.8 ± 10.2) mmol/L vs. (126.4 ± 10.8) mmol/L and (102.3 ± 8.6) mmol/L vs. (108.5 ± 8.9) mmol/L;Da-cvO2:(19.6 ± 3.9) mmol/L vs. (23.0 ± 4.5) mmol/L, and there were statistical differences (P<0.05). Conclusions Phenylephrine has more effect on tissue oxygen metabolism in the elderly patients undergoing fluid-restricted abdominal surgery.

Objective To establish a stable and reliable HPLC method and fingerprint reference substance for the measurement of the fingerprint, the practical quality control, and assay of the water-soluble components of Salvia miltiorrhiza. Methods The HPLC was run on C 18 columns with methanol-1.0 % glacial acetic acid solution as mobile phase in gradient elution mode at a flow rate of 1.0 mL/min. The chromatographic system suitability, the gradient elution mode, mobile phase acidity, and the effect of column type on fingerprint repeatability were tested. Results The HPLC fingerprints of the water-soluble extract of reference S. miltiorrhiza were obtained with very good resolution under the established chromatographic system. Fifteen peaks in the chromatograms were selected for the fingerprint identification and quality control of S. miltiorrhiza. The quality of ten batches of S. miltiorrhiza samples from different hibitats were assessed by comparing their chromatographic fingerprints with the reference fingerprints obtained at the same time, and the similarity showed no difference, eventhough the column filler was changed. Conclusion Because the inherent complexity of medicinal material components has been reflected by chromatographic fingerprints, there are many factors affecting the fingerprint repeatability for the changes of column type. The results of the quality assessment of S. miltiorrhiza, using fingerprints from different columns, are not all coincidence. In order to obtain the comparable and repeatable results in different laboratories, it is much practical with both a defined chromatographic system suitability and a fingerprint reference substance.
