OBJECTIVE To establish the fingerprint of Bushen ningshen ointment， determine the contents of its major constituents， and investigate its in vitro antioxidant activity. METHODS High performance liquid chromatography （HPLC） fingerprints of 10 batches of Bushen ningshen ointment were established. Similarity evaluation and identification of common peaks were subsequently performed. The contents of 10 components such as salidroside were determined using the same HPLC method. Using the scavenging rates against 2，2′-azino bis（3-ethylbenzothiazoline-6-sulfonic acid） （ABTS） and 1，1-diphenyl-2- picrylhydrazyl （DPPH） radicals， as well as ferric ion reducing antioxidant power （FRAP） as indicators， the anti-oxidant activity of the ointment was evaluated； grey relational analysis and partial least squares regression were conducted using SIMCA 14.1 software to establish the spectrum-effect relationship. RESULTS The fingerprint chromatogram of 10 batches of Bushen ningshen ointment contained 24 common peaks， with similarity values all exceeding 0.96. Eleven peaks were identified as adenosine （peak 1）， salidroside （peak 4）， morroniside （peak 6）， catechin （peak 7）， paeoniflorin （peak 10）， spinosin （peak 11）， ferulic acid （peak 12）， isoquercitrin （peak 13）， E-mail：wli1743@163.com verbascoside （peak 14）， paeonol （peak 23）， and emodin （peak 24）. Content determination results showed that the average contents of salidroside， morroniside， catechin， paeoniflorin， spinosin， ferulic acid， isoquercitrin， verbascoside， paeonol， and emodin were 0.725， 1.962， 0.214， 3.395， 0.124， 0.107， 0.286， 0.019， 0.034 and 0.067 mg/g， respectively. The antioxidant potency composite index （APC） for the 10 batches ranged from 85.08% to 96.35%. Spectrum-effect relationship analysis indicated that all 24 common peaks were positively correlated with the antioxidant capacity. Seventeen peaks had variable importance in projection values ＞1， specitically peaks 2， 5， 6， 7， 9， 10， 13- 21， 23， and 24. CONCLUSIONS This study successfully established the HPLC fingerprint and content determination method for Bushen ningshen ointment. The compounds represented by the 17 common peaks such as morroniside may be the active components contributing to its antioxidant effects.

Lipidomics is an emerging discipline that systematically studies the various types, functions, and metabolic pathways of lipids within living organisms. This field compares changes in diseases or drug impact, identifying biomarkers and molecular mechanisms present in lipid metabolic networks across different physiological or pathological states. Through employing analytical chemistry within the realm of lipidomics, researchers analyze traditional Chinese medicine (TCM). This analysis aids in uncovering potential mechanisms for treating diverse physiopathological conditions, assessing drug efficacy, understanding mechanisms of action and toxicity, and generating innovative ideas for disease prevention and treatment. This manuscript assesses recent literature, summarizing existing lipidomics technologies and their applications in TCM research. It delineates the efficacy, mechanisms, and toxicity research related to lipidomics in Chinese medicine. Additionally, it explores the utilization of lipidomics in quality control research for Chinese medicine, aiming to expand the application of lipidomics within this field. Ultimately, this initiative seeks to foster the integration of traditional medicine theory with modern science and technology, promoting an organic fusion between the two domains.

Objective To construct a whole process nursing plan for women with vaginal delivery and to evaluate its effect.Methods On the basis of literature analysis and Delphi expert consultation method,a whole process nursing plan of vaginal delivery was established.From June to September 2023,180 primiparas in a tertiary A hospital in Ningxia were selected as research subjects to carry out the preliminary application of the plan.Among them,the parturients hospitalized from August to September were in the experimental group,and those hospitalized from June to July were in the control group.The experimental group received the whole process nursing plan on the basis of routine nursing,and the control group received routine nursing.The indexes related to delivery outcomes(delivery mode,time of each labor stage,et al),the degree of labor pain,fear of labor and labor experience were compared between the 2 groups.Results The effective recovery rates of the 2 rounds of expert correspondence were 100％and 93.75％,respectively,and the coefficient of expert authority was 0.85.The finally constructed plan included 3 first-level items,10 second-level items and 29 third-level items.86 cases and 85 cases were included in the experimental group and the control group,respectively.After intervention,there were statistically significant differences in each stage of labor between the 2 groups(P＜0.05).There was significant difference in the rate of good and good control of labor pain(x2=16.386,P＜0.001).The childbirth fear questionnaire score(27.76±3.60)of the experimental group was lower than(33.06±3.36)of the control group,and the childbirth experience score(80.83±4.83)was higher than(75.79±3.46)of the control group,and the differences were statistically significant(P＜0.001).Conclusion The whole process nursing plan of vaginal delivery is scientific and feasible.It can shorten the labor time,relieve labor pain,labor fear and improve labor experience.

Reduced or interrupted blood flow is an important pathological and physiological process in femoral head necrosis,so understanding the blood flow of the femoral head can help better understand the progression of femoral head necrosis.With the continuous development and improvement of imaging technology,the technical methods for detecting the blood flow of the femoral head are gradually being widely applied,allowing clinical physicians to better understand the blood flow situation of patients with femoral head necrosis.However,at present,the prognosis prediction of femoral head necrosis still mainly revolves around factors such as the area and angle of femoral head necrosis.Therefore,this article explores imaging techniques covering studies such as femoral head vascular imaging or blood flow perfusion parameters,summarizes their application research progress in femoral head necrosis blood flow assessment,and aims to provide more objective basis for exploring the prevention and prognosis of femoral head necrosis from the perspective of femoral head blood flow.

Objective:To explore the correlation between intrahepatic cholestasis of pregnancy(ICP)and ad-verse pregnancy outcomes.Methods:A total of 511 singleton pregnant women with ICP treated at The Third Affili-ated Hospital of Guangzhou Medical University from August 2017 to January 2024 were selected as the study sub-jects.Among them,patients were divided into the adverse pregnancy outcome group(n=49)and the control group without adverse pregnancy outcomes(n=462).The general and clinical data of the two groups were com-pared and analyzed.Results:①General situation:The number of pregnancies and deliveries,ICU transfer rate,total hospital stay,and total hospitalization costs were significantly higher in the adverse pregnancy outcome group compared to the control group(P<0.05).The number of prenatal check-ups,diagnostic gestational weeks,and gestational weeks at delivery were significantly lower compared to the control group(P<0.05).②Clinical symp-toms:The incidence of itching in the adverse pregnancy outcome group was lower compared to the control group(10.2%vs.26.6%,P<0.05),while other symptoms such as rash,fatigue,jaundice,and gastrointestinal symp-toms showed no significant difference between the two groups(P>0.05).③Laboratory examinations:Compared with the control group,patients in the adverse pregnancy outcome group had significantly the increased levels of alanine aminotransferase,aspartate aminotransferase,uric acid,urea nitrogen,and triglycerides,and significantly the decreased levels of alkaline phosphatase and fasting blood glucose,with statistical significance(P<0.05).Other biochemical indicators showed no significant difference between the two groups(P>0.05).④ICP grading and complications:The proportion of early-onset ICP,severe and very severe ICP in the adverse pregnancy out-come group was significantly higher compared to the control group(P<0.001);the proportion of adverse preg-nancy outcome group with pregnancy-induced hypertension was significantly higher compared to the control group;the incidence of preterm birth,fetal growth restriction,meconium-stained amniotic fluid,and fetal distress in the adverse pregnancy outcome group was significantly higher compared to the control group(P<0.001).⑤Neo-natal outcomes:The neonatal Apgar scores(1 min,5 min,10 min)and neonatal weight in the adverse pregnancy outcome group were lower compared to the control group(P<0.001),and the incidence of mild neonatal asphyx-ia was significantly higher,with a statistically significant difference(P<0.001).Conclusions:The severity of ICP is closely related to the occurrence of adverse pregnancy outcomes.Therefore,it is clinically necessary to pay at-tention to the grading of ICP,closely monitor the levels of total bile acids and liver enzymes,and try to avoid ad-verse pregnancy outcomes,especially intrauterine fetal death.

Objective:To investigate the cortical activation characteristics of patients with post-stroke foot drop during task-oriented ankle rehabilitation robot training using functional near-infrared spectroscopy(fNIRS).Method:Twenty patients with post-stroke foot drop were recruited.A 51-channel fNIRS system were used to measure changes in oxygenated hemoglobin(HbO2)in the cortical regions during task-oriented ankle rehabilita-tion robot training.The regions of interest(ROIs)included the bilateral dorsolateral prefrontal cortex(DLP-FC),primary motor cortex(M1),primary somatosensory cortex(S1),premotor area and supplementary mo-tor area(pSMA),and inferior frontal gyrus(IFG).Data processing and statistical analysis were conducted us-ing MATLAB(R2021b)and SPSS 25.0 software.Result:Significant cortical activation was observed in channels 19,26,28,29,35,36,39,42,and 48(P＜0.05)during task-oriented ankle rehabilitation robot training in patients with post-stroke foot drop.Based on the channel-to-brain region registration,significant activation was noted in the bilateral pSMA,bilateral DLPFC,unaffected side S1,and unaffected side IFG's area.Conclusion:Task-oriented ankle rehabilitation robot training can lead to increased cortical activation in pa-tients with post-stroke foot drop,which may represent a potential neural mechanism underlying its therapeutic effects.
