AIM: To establish the determination of narigin and hesperidin in Juhong Pills(Exocarpium, Citri Grandis, Pericarpium Citri Reticulatae, Radix Angelicae Sinensis, etc.). METHODS: The extraction was completed with ether. The Shim-pack ODS(?6.0mm?150mm) column was used with mobile phase of CH 3OH-CH 3COOH-H 2O(30∶4∶60). The detection wavelength was at 283nm. RESULTS: The linear range for narigin was 0.072~1.43?g, r=0.9999 and the linear range for hesperidin was 0.068~1.37?g, r=0.9999, respectively. Both the average recoveries were 99.3% and 99.4%, respectively. Both RSD were 0.6%(n=5). CONCLUSION: The method is simple and the result is reliable.

Objective To explore the predictive value of blood lipid dynamics of septic shock for the short-term prognosis.Methods A total of 107 patients with septic shock treated in Dongzhimen Hospital of Beijing University of Traditional Chinese Medicine from March 2019 to July 2023 were selected as the study subjects.They were divided into survival group(n=76)and death group(n=31)based on their 28-day outcomes.Total cholesterol(TC),triacylglycerol(TG),high density lipoprotein cholesterol(HDL-C)and LDL cholesterol(LDL-C)concentrations were tested at disease onset(day 0),day 4±1 and day 7±1.The receiver operating characteristic(ROC)curve was used to analyze the predictive value of lipid dynamics on outcomes in patients with septic shock.Multivariate COX regression analysis was used to analyze factors affecting the prognosis of patients with septic shock.Result The levels of TC and HDL-C at disease onset,as well as TC,HDL-C and LDL-C on day(4±1)and day(7±1)in the survival group were higher than those in death group,and the differences were significant(Z=2.241~5.744,all P<0.05).The areas under the curve[AUC(95%)]for the prediction of changes in HDL-C and LDL-C in the first week of admission were 0.775(95%CI:0.685~0.850)and 0.646(95%CI:0.547~0.736),with the best cutoff values of 0.16mmol/L and 0.28mmol/L,sensitivity of 70.97%and 64.52%,and specificity of 82.89%and 69.74%,respectively.Multivariate regression analysis showed that HDL-C dynamics was independently associated with poor prognosis(OR=0.141,95%CI:0.044~0.454,P=0.001).Conclusion Monitoring the dynamic changes of blood lipid at the first week of admission could help in predicting short-term outcomes in patients with septic shock.
