ABSTRACT
Objective:To observe the clinical effects of hot-wet compression with Xiaohua ointment for acne mastitis in mass stage and its impacts on humoral immune function and inflammation.Methods:85 cases of patients with acne mastitis in mass stage treated in our hospital from January 2018 to January 2019 were selected as the research objects and randomly divided into control group (42 cases) and observation group (43 cases). The control group taken Tuoli xiaodu powder and external use of purple detumescence cream, and the observation group received hot-wet compression with Xiaohua ointment additionally. All treated for 30 days. The clinical efficacy, symptom scores, breast mass size, humoral immune indexes, C-reactive protein (CRP) and erythrocyte sedimentation rate (ESR) were compared, and the adverse reactions were recorded.Results:After treatment, the humoral immune indexes of the two groups had no significant change ( P>0.05), but the pain score, breast tumor size, mass score, CRP and ESR were significantly decreased than those before treatment ( P<0.05); compared with the control group, the pain score, breast tumor size and mass score in the observation group were significantly lower than those in the control group ( P<0.05). The total effective rate of the observation group was 83.7%, which was significantly higher than 59.5% of the control group ( P<0.05). There were no obvious adverse reactions in both groups. Conclusions:Hot-wet compression with Xiaohua ointment is effective and safe for patients with acne mastitis in mass stage, and could improve their inflammation.
ABSTRACT
Objective:To estimate the pharmacokinetics for two solution types of propofol glycoside in-jections in rats .Methods:A high performance liquid chromatography-high resolution mass spectrometry ( HPLC-MS) was established for measuring propofol in rat plasma .Two kinds of propofol glycoside injec-tions were developed and intravenously administered to rats via tail vein , respectively , and a commercial-ly available propofol emulsion injection was intravenously administered as a control .Propofol plasma concentration-time curves were determined , and the pharmacokinetic parameters were estimated .Re-sults:HPLC-MS measurement was performed by using a quadrupole-orbit trap high-resolution mass spec-trometer on a C18 chromatographic column.The mobile phase consisted of water and methanol (20∶80, V/V) .The ion source was an atmospheric pressure chemical ion source , and the negative ion was used for detection with a scanning mode of selective ion monitoring in which m/z 177.127 4 was used for propofol and m/z 149.096 1 used for thymol as an internal standard .A linear correlation between con-centration and peak area ratio was constructed in the range of 50 μg/L-10.0 mg/L propofol.The limit of quantification was 50μg/L propofol .The average recoveries of propofol from plasma were in the range of 93.6% -101.1%, and intra-day or inter-day relative standard deviation for measurement was <14%.The pharmacokinetic results showed that the two kinds of propofol glycoside injections exhibited the same pharmacokinetic behavior .However, the clearance and area under curve values of propofol for the two propofol glycoside injections were evidently increased as compared with those for propofol emulsion injection, respectively.Furthermore, their apparent distribution volumes were increased as well .Never-theless, the propofol elimination half-life (t1/2) value of the newly developed propofol glycoside injections was the same as that of commercial propofol emulsion injection (approximately 1.5 h).Conclusion:The established HPLC-MS method can be used for measuring propofol concentration accurately in rat plasma . The clearance and distribution volumes of propofol glycoside injection are bigger than those of the propofol emulsion injection .
