Objective To develop a HPLC-MS/MS method for comprehensive monitoring and control of the raw material feeding (honeysuchle flowers extract and baikal skullcap root extract) , and simultaneous determination of chlorogenic acid and baicalin in Yinhuang capsules. Methods The separation was performed on an Inertsil ODS-3 (2.1 mm × 150 mm, 5 μm) analytical column with the mobile phase consisting of methanol- 10 mmol/L ammonium acetate solution by gradient elution program, and the column temperature was 40 ℃. Active ingredients were separated by HPLC, and the Electrospray Ionization Mass (API) source was applied and operated in the negative ion mode, and reactions ion monitoring mode (MRM) for quantitative analysis were selected. Results The samples and the mixed Extract have the same characteristic peak in MS and MS/MS. According to the prescription feeding process, the proprietary Chinese medicine wasdetermined. The results showed that the palladium residue of 6 batches samples were up to the standard by HPLC/MS/MS chromatographic peak areas. The calibration cruve of chlorogenic acid and baicalin were linear: 0.60-4.80 μg/ml (r = 0.9989),2.87-14.40 μg/ml (r = 0.9986), with the relative standard deviation of repeatability by 0.69% and 0.69% respectively, and the mean recovery rate were 95%-102%, 95%-103%, respectively. Conclusions The method was proven to be simple, accurate, reliable, high sensitive and can be used for determination and control of the raw material feeding (honeysuchle flowers extract and baikal skullcap root extract) and quality in Yinhuang capsules.

Objective The monitoring of the feeding situation of active pharmaceutical ingredient in Shendan-Chenpi tablet by HPLC-MS/MS,and the content of sodium taurocholate and hesperidin.Methods Using ZORBAX Eclipse Plus C18(4.6 mm×250 mm, 5 μm)Column temperature 40 ℃, Mobile phase with acetonitrile-10 mmol/sodium acetate solution, using gradient elution program. Active ingredients were separated by HPLC, and the Electrospray Ionization Mass (ESI) source was applied and operated in the negative ion mode, and reactions ion monitoring mode(MRM) for quantitative analysis were selected. Results The proprietary Chinese medicine is judged by the prescription feeding process, through analysis and contrast of the medicinal materials, reference substance of primary mass spectrogram, secondary mass spectrogram of peak. The aurocholic acid sodium and hesperidin had a good linear relationship in 0.242×10-2-1.45×10-2μg(r=0.996 0), 0.688×10-2-10.30×10-2μg(r=0.999 2), and the precision test were 0.78% and 1.56%, and the recovery rate were 102%-103%,96%-109%. Conclusions The method was simple, accurate and reliable, high sensitive and fast. The comprehensive monitoring was applied to the Shedan-Chenpi tablet in feeding analysis and quality.

Objective:To explore the application effects of application of rehabilitation care decision-making scheme based on case management model in severe burn patients.Methods:The study was a non-randomized historical control study. Thirty patients who met the inclusion criteria and received routine rehabilitation nursing in the First Affiliated Hospital of Army Medical University (the Third Military Medical University, hereinafter referred to as the hospital) from April 2021 to March 2022 were included in routine rehabilitation nursing group (26 males and 4 females, aged 48.50 (31.75, 56.25) years), and 30 patients who met the inclusion criteria and received case management rehabilitation nursing in the hospital from April 2022 to March 2023 were included in case management rehabilitation nursing group (22 males and 8 females, aged 46.00 (36.75, 55.25) years). The length of intensive care unit (ICU) stay, total hospitalization day, and total hospitalization cost of the patients in two groups were recorded. At admission, convalescence, discharge, and 6 months after injury, the patients' life quality was evaluated by the concise burn specific health scale, the sleep quality was evaluated by the Pittsburgh sleep quality index, and the functional independence was evaluated by the functional independence rating scale. At convalescence, discharge, and 6 months after injury, the patients' scar status was evaluated by the Vancouver scar scale. At 6 months after injury, a third-party satisfaction questionnaire was used to investigate the efficacy satisfaction of patients.Results:The length of ICU stay and total hospitalization day of patients in case management rehabilitation nursing group were both significantly shorter than those in routine rehabilitation nursing group (with Z values of -1.97 and -1.99, respectively, P<0.05), and the total hospitalization cost was less than that in routine rehabilitation nursing group ( Z=-1.99, P<0.05). At discharge and 6 months after injury, the life quality scores of patients in case management rehabilitation nursing group were significantly higher than those in routine rehabilitation nursing group (with t values of -3.19 and -4.43, respectively, P<0.05), while the sleep quality scores were significantly lower than those in routine rehabilitation nursing group (with Z values of -2.18 and -3.33, respectively, P<0.05). There were no statistically significant differences in cognitive function scores of functional independence of patients between the 2 groups at admission, convalescence, discharge, and 6 months after injury ( P>0.05). The exercise function scores and total scores of functional independence of patients in case management rehabilitation nursing group at convalescence, discharge, and 6 months after injury were significantly higher than those in routine rehabilitation nursing group (with Z values of -4.37, -2.73, -4.10, -4.37, -2.64, and -4.06, respectively, P<0.05). The scar pigmentation scores of patients in case management rehabilitation nursing group at 6 months after injury were significantly lower than those in routine rehabilitation nursing group ( Z=-2.05, P<0.05), and the scar vascularity scores of patients in case management rehabilitation nursing group at discharge and 6 months after injury in case management rehabilitation nursing group were significantly lower than those in routine rehabilitation nursing group (with Z values of -3.16 and -2.07, respectively, P<0.05). The scar pliability scores (with Z values of -3.16, -2.45, and -4.38, respectively, P<0.05), thickness scores (with Z values of -2.56, -2.35, and -4.70, respectively, P<0.05), and total scores (with Z values of -3.77, -3.04, and -3.13, respectively, P<0.05) of patients in case management rehabilitation nursing group at convalescence, discharge, and 6 months after injury were significantly lower than those in routine rehabilitation nursing group. At 6 months after injury, the efficacy satisfaction scores of patients in case management rehabilitation nursing group were 4.00 (3.00, 4.25), which were significantly higher than 3.00 (2.00, 4.00) in routine rehabilitation nursing group ( Z=-2.72, P<0.05). Conclusions:The implementation of rehabilitation care decision-making scheme based on case management model can optimize the cost efficiency, improve the effectiveness of clinical treatment, and enhance the life quality and satisfaction of the curative effect of severe burn patients.
