To establish a size exclusion high-performance liquid chromatography (SEC-HPLC) method for the determination of the purity of recombinant human basic fibroblast growth factor (rh-bFGF).

The purity of rh-bFGF solution was determined using TSK G2000SWXL column and high-performance liquid chromatography, and the specificity, repeatability, precision, detection limit, stability, and durability of the method were evaluated.

The blank solvent has no interference with the rh-bFGF main peak, and the degradation impurities under various destruction conditions didn't interfere with the determination of the rh-bFGF peak, and the purity index of the rh-bFGF peak was greater than 990. The repeatability and intermediate precision experimental results showed that the separation degree of impurities and the rh-bFGF main peak was greater than 1.5, and the RSD was 0.36% and 0.64%, respectively. The detection limit was 0.185 μg·mL^-1. The durability experiment results show that fluctuations in flow rate, column temperature, and wavelength had no effect on the detection results, and the RSD of each condition was less than 2.0%.

The SEC-HPLC method developed has the advantages of simple operation, accurate results, strong specificity, high stability and good applicability, and can be used for rh-bFGF purity determination.

To develop a quantitative analysis of multi-components by single-marker (QAMS) method for simultaneous determination of six major components (nitidine chloride, chelerythrine, hesperidin, zanthoxylumol, dictamnine and pimpinellin) in Toddalia asiatica.

A reversed-phase high-performance liquid chromatography (HPLC) method was adopted using a Waters Symmetry C₁₈ column (250 mm × 4.6 mm, 5 μm). The mobile phase consisted of 0.1% formic acid aqueous solution and acetonitrile (containing 0.1% formic acid) with gradient elution. The flow rate was set at 0.8 mL·min^-1, the detection wavelength was 280 nm, and the column temperature was maintained at 30 ℃. Taking hesperidin as the reference standard, relative correction factors (RCFs) of the other five components were determined, and the contents of the six major components were calculated. The accuracy and feasibility of the QAMS method were verified by investigating the robustness of RCFs and comparing the results with those obtained by the external standard method.

Within the linear range, the RCFs of nitidine chloride, chelerythrine, zanthoxylumol, dictamnine and pimpinellin were 0.170, 0.353, 3.443, 1.546 and 0.664, respectively. The RCFs exhibited good robustness under different experimental conditions (RSD < 3%). Additionally, there was no significant difference between the results obtained by the QAMS method and the external standard method for the analysis of eight batches of Toddalia asiatica.

The developed QAMS method is accurate and feasible, which can be used for determining the contents of major components in Toddalia asiatica.

To investigate the residue of mycotoxins in Fukang tablets.

The multi-in-one immunoaffinity columns were used to establish a UPLC-MS/MS quantitative analysis method, which was applied to analyze 29 batches of samples collected from six manufacturing enterprises.

The linear relationship of 11 mycotoxins was good within their respective linear ranges, with the correlation coefficient r ranging from 0.996 4 to 0.999 9 and the limit of quantitation (LOQ) ranging from 0.4 to 40 ng/tablet. The average recovery rate of 11 mycotoxins was 74.0% to 115.7%, and the RSD ranged from 2.6% to 11.3%. Among 29 batches of Fukang Tablets, except one batch in which fumonisin B3 (FB3) was measured at 10.4 ng/tablet, while the mycotoxin levels in the other samples were all less than 5 ng/tablet.

This method is rapid, accurate, highly sensitive, and reproducible, making it suitable for the quantitative detection and safety evaluation of multiple mycotoxins in Fukang tablets with complex matrix components.

To compare the efficacy and safety of Remimazolam versus propofol combined with nalbuphine for painless gastroenteroscopy anesthesia in alcoholics.

A total of 90 alcoholic patients from Dongguan Songshan Lake Central Hospital from January 2022 to March 2023 were randomly assigned into two groups using a random number table. The observation group (n=45) received remimazolam combined with nalbuphine, while the control group (n=45) received propofol combined with nalbuphine. The onset time of anesthesia, awakening time, recovery time, heart rate (HR), respiratory rate (RR), pulse oxygen saturation (SpO₂) and mean arterial pressure (MAP) were recorded. Pain levels were assessed using the Visual Analog Scale (VAS), and sedation levels were assessed using the Ramsay Sedation Scale.

The onset time, awakening time and recovery time of anesthesia were significantly shorter in the observation group compared to the control group (P<0.05). Both groups experienced significant decreases in HR, RR, SpO₂ and MAP after endoscopy compared to pre-procedure levels (P<0.05), with the observation group significantly more stable hemodynamic parameters (P<0.05). The VAS and Ramsay Scores were significantly lower in the observation group at 5 and 30 minutes after anesthesia awakening (P<0.05). The incidence of adverse reactions was significantly lower in the observation group than in the control group (P<0.05).

Compared with propofol combined with nalbuphine, remimazolam combined with nalbuphine offered superior efficacy and safety for painless gastroscopy anesthesia in alcoholic patients.
