OBJECTIVE To optimize the optimum processing technology of vinegar-processed Artemisiae Argyi Folium(AAF),and analyze the difference of index components and analgesic activity before and after processing.METHODS The method for the determination of total flavonoids and total terpenes in AAF was established with eupatilin and Santamarine as control substances,re-spectively.The HPLC-VWD method was established for the simultaneous determination of 6-Methoxytricin,Santamarine,eupatilin and Artemisolide in AAF.Box-Behnken design-response surface method was used to optimize the processing technology of vinegar-processed AAF,with the content of total flavonoids,total terpenes and four active ingredients as the index,and the amount of rice vin-egar,moistening time,processing temperature and processing time as the factors.The quantitative analysis was combined with hierar-chical cluster analysis(HCA),principal component analysis(PCA)and orthogonal partial least squares discriminant analysis(OPLS-DA)to evaluate the difference of index components before and after processing.The analgesic activity before and after processing was investigated using pain mice induced by formalin.RESULTS The optimum processing parameters of vinegar-processed AAF were 16%rice vinegar dosage,moistening time 50 min,processing temperature 160℃and processing time 12 min.There were significant differences in the content of index components before and after processing.The analgesic activity of vinegar-processed AAF was signifi-cantly better than that of AAF.CONCLUSION The optimized processing technology is stable and feasible,which can provide scien-tific basis for standardizing production of vinegar-processed AAF.

Objective To investigate the relationship between the triglyceride glucose product(TyG)in-dex,plasma arteriosclerosis index(AIP),systemic immune inflammation index(SII),and the severity of acute coronary syndrome(ACS)and coronary artery stenosis degree in patients.Methods A retrospective analysis was conducted on patients who underwent coronary angiography at the hospital from November 2021 to De-cember 2023 due to suspected coronary heart disease,and they were divided into an ACS group(1 446 cases)and a control group(690 cases).General baseline and laboratory data of the patients were collected,and TyG index,AIP and SII in were calculated.Gensini score was used to evaluate the degree of coronary artery steno-sis.The risk factors of ACS were determined by binary multivariate Logistic regression analysis.Receiver op-erating characteristic(ROC)curve was drawn to analyze the diagnostic value of various indicators for the de-gree of coronary artery stenosis in ACS patients.Results TyG index,AIP and SII in ACS group were signifi-cantly higher than those in control group(P＜0.05).Binary multivariate Logistic regression analysis results showed that TyG index,AIP and SII were risk factors for ACS(P＜0.05).The ROC curve results showed that TyG index,AIP and SII had certain diagnostic value for the degree of coronary artery stenosis in ACS pa-tients.According to the cut off values of TyG index,AIP,and SII,the patients were further divided into differ-ent subgroups,the Gensini scores in the high TyG index,AIP,and SII groups were significantly higher than those in the low TyG index,AIP,and SII groups(P＜0.05).Conclusion TyG index,AIP and SII are closely related to ACS,which could be used as simple laboratory indexes for diagnosis of ACS,and also have good di-agnostic value for the coronary artery stenosis degree.

OBJECTIVE:To improve the method for the determination of 2 main components in Ticarcillin disodium and potas-sium clavulanate for injection. METHODS:HPLC was performed on the column of Waters XBridgeTM C18 with mobile phase of 0.01 mol/L ammonium dibasic phosphate solution(pH 7.0)-menthol(80:20,V/V)at a flow rate of 1.0 mL/min,the detection wave-length was 220 nm, column temperature was 30 ℃, and injection volume was 20 μL. RESULTS:The linear range was 1.95-195.22 μg/mL for ticarcillin (r=0.9999) and 0.12-12.18 μg/mL for clavulanate(r=0.9999);RSDs of precision,stability (under 4 ℃) and reproducibility tests were lower than 1.0%;recoveries were 99.3%-100.5%(RSD=0.4%,n=9) and 99.2%-101.0%(RSD=0.7%,n=9). CONCLUSIONS:The method is rapid,accurate and reliable,and can be used for the determination of 2 main components in Ticarcillin disodium and potassium clavulanate for injection.
