Objective To evaluate the efficacy of an online-to-offline(O2O)health education guided by the'Timing Theory'in improving self-management behaviours among the patients with glaucoma after day surgery.Methods In this randomised controlled study conducted between July and December 2022,70 patients with glaucoma after day surgery in our hospital were assigned to a control group and an experimental group,with 35 patients per group.Patients in control group received routine nursing care,while those in experimental group received O2O health education based on timing theory in addition to the routine nursing care.Outcomes were evaluated using the glaucoma awareness and knowledge questionnaire(GAKQ),self-efficacy to manage chronic disease scale(SEMCD)and glaucoma self-management questionnaire(GSMQ)at baseline,at 1 month and 3 months after surgery.Results A total of 32 patients in the experimental group and 27 in the control group completed the study.The generalised estimating equation(GEE)analysis showed a significant difference,respectively,in total score of GSMQ in interaction effect(F=8.408,P=0.015)and SEMC in time main effect(F=54.660,P<0.001).There were significant differences in total scores of GAKQ in time main effect,inter-group main effect and interaction effect(F=128.483,P<0.001;F=7.991,P<0.05;F=32.652,P<0.001,respectively).At one-month after intervention,the experimental group showed significantly higher GAKQ and SEMCD scores than the control group(Z=-2.004,P<0.05;Z=-2.029,P<0.05,respectively).At 1-and 3-months after intervention,the experimental group demonstrated significantly higher GAKQ scores(Z=-3.987,P<0.001;Z=-4.505,P<0.001,respectively).Conclusion The timing theory based O2O health education significantly improves knowledge of glaucoma,self-efficacy and self-management behaviours among day surgery patients and helps patients better cope with perioperative self-management over day surgery.

Objective To investigate the effects and mechanisms of combined prescriptions of essential oils from five traditional Chinese medicinal herbs,namely peppermint,turmeric,ginger,Tibetan fennel,and cumin,on symptoms related to functional abdominal pain syndrome(FAPS).Methods Gas chromatography-mass spectrometry(GC-MS)was employed to analyze the chemical constituents of five essential oils,while network pharmacology was utilized to predict the key targets and signaling pathways associated with these essential oils in alleviating functional abdominal pain syndrome.A formula design methodology centered on these core targets and signaling pathways was developed for creating new prescriptions.Molecular docking technology was conducted to predict its the underlying mechanisms.Subsequently,animal experiments were performed to assess pharmacological activity,including hot plate tests and acetic acid-induced writhing assays to validate the analgesic effects of the newly formulated prescription,as well as xylene-induced ear swelling tests to evaluate its anti-inflammatory properties.The impact of the essential oil formulation on intestinal peristaltic function was examined through intestinal propulsion experiments.Additionally,enzyme-linked immunosorbent assay(ELISA)methods were employed to measure levels of serotonin(5-HT),prostaglandin E2(PGE2),and gamma-aminobutyric acid(GABA)in brain tissue.Western blot analysis was conducted to determine protein expression levels of TPH1 and SERT in the intestine,along with TPH2 and SERT in the brain.Results The main chemical components in five essential oils were identified and screened(peppermint:12,turmeric:8,ginger:14,cumin:2,fennel:6).Based on the network pharmacology analysis,four new essential oil prescriptions were successfully designed according to the complementary relationship between the five essential oils in improving functional abdominal pain syndrome at the target level,including 4 new prescription named Prescription A,B,C and D,these four prescriptions were all based on ginger and turmeric essential oils,with other essential oils serving as supplements or enhancements.The results of animal experiments showed that Prescription D could significantly reduce the writhe frequency of mice(P<0.05),all the four groups could significantly prolong the pain threshold of mice(P<0.05),and Prescription C had a significant effect on reducing the degree of ear swelling(P<0.05).The prescription of essential oil did not significantly affect the function of peristalsis and the speed of propulsion.The levels of 5-HT and PGE2 in the brain tissue were significantly inhibited(P<0.05),and the level of GABA was significantly increased(P<0.05).Prescription C could reduce the expression of TPH1 in the intestinal tissue(P<0.05),Prescription A,C and D could reduce the expression of TPH2,and all groups had a tendency to increase the expression of SERT in the brain tissue.Conclusion In summary,the therapeutic effects of the four novel prescriptions composed of the five essential oils demonstrated potential in improving symptoms related to FAPS,the mechanism might be through modulating abnormalities in the brain-gut axis system.

Objective To explore the effect of evening primrose oil(EPO)on aortic endothelial damage in rats with polycystic ovary syndrome(PCOS),using network pharmacology and in vivo experiments.Methods The potential targets of EPO for improving aortic endothelial injury in PCOS rats were predicted by network pharmacology,and the selected core targets and renin-angiotensin signaling(RAS)pathway were verified by experiments.Fifty-eight female SD rats were divided randomly into a blank group(n=10)and a modeling group(n=48).Rats in the blank group were fed a normal diet and rats in the modeling group received a high-fat diet for 8 weeks.The PCOS model was prepared at week 6 by administration of letrozole(1 mg/(kg·d))for 21 days.Blood was taken from the tail vein after modeling and serum was collected to detect hormone levels.The model rats were then divided randomly into four groups and treated with the corresponding drugs for 6 weeks.Blood,blood vessels,and ovaries were then collected.Tissue morphology was examined by hematoxylin and eosin staining and serum levels of luteinizing hormone(LH),testosterone(T),follicle-stimulating hormone(FSH),endothelin(ET-1),and tumor necrosis factor(TNF-α)were detected by enzyme-linked immunosorbent assay(ELISA).Serum levels of nitric oxide(NO)were determined by spectrophotometry.Protein expression levels of core targets and RAS pathway-related factors were assessed by western blotting and immunohistochemistry.Results Twenty-five intersection targets of EPO and PCOS were identified by network pharmacological analysis.Kyoto encyclopedia of genes and genomes analysis showed that EPO improved vascular injury in PCOS rats via multiple pathways,including RAS.Serum levels of ET-1,FSH,LH,and T measured by ELISA were significantly decreased after EPO treatment,compared with the model group(P＜0.01).EPO significantly decreased the expression levels of Ang Ⅰ,VEGF-B,AT2R,ET-1,and TNF-α proteins in the aorta(P＜0.01)and significantly increased expression levels of Ang Ⅱ,CD31,and endothelial NO synthase proteins(P＜0.01).Conclusions EPO may ameliorate vascular endothelial injury in PCOS model rats by inhibiting the RAS signaling pathway and by overactivation of the ACE/Ang Ⅱ/AT1 axis.

Objective To establish dynamic nomogram models for postoperative recurrence and survival risk of patients with AFP-negative hepatocellular carcinoma(ANHC)based on multimodal clinical data,to identify ANHC-specific prognostic biomarker combinations by integrating tumor biological characteristics and treatment response parameters through machine learning,and to provide an individualized risk assessment tool for overcoming the limitations of traditional serum biomarkers.Methods A retrospective analysis was performed for 421 ANHC patients who underwent hepatectomy in Eastern Hepatobiliary Surgery Hospital from April 2012 to December 2018,and they were randomly divided into training group with 210 patients and validation group with 211 patients.The univariate and multivariate Cox proportional-hazards regression models were used to identify independent prognostic factors and establish a nomogram model,and the receiver operating characteristic(ROC)curve,the calibration curve,and the decision curve analysis were used to assess the performance of the model.Related indicators were measured,including prealbumin(PA),white blood cell count(WBC),tumor size,and microvascular invasion.The chi-square test or the Fisher's exact test was used for comparison of categorical variables between two groups,and the independent-samples t test or the Mann-Whitney U test was used for comparison of continuous variables between two groups.Results The multivariate analysis showed that multiple tumors(hazard ratio[HR]=3.30,P<0.001),WBC(HR=1.05,P=0.005),blood glucose(HR=1.15,P=0.026),CA19-9(HR=1.17,P=0.005),and tumor size(HR=1.17,P<0.001)were independent risk factors for disease-free survival(DFS),while PA(HR=0.99,P=0.022)was a protective factor.Incomplete tumor capsule(HR=0.60,P=0.009),age(HR=1.02,P=0.035),prothrombin time(PT)(HR=1.27,P=0.023),CA19-9(HR=1.01,P<0.001),and tumor size(HR=1.15,P<0.001)were independent risk factors for overall survival(OS).The DFS nomogram achieved an AUC of 0.74(95%confidence interval[CI]:0.64-0.84)in the training group and 0.67(95%CI:0.57-0.77)in the validation group,while the OS nomogram had an AUC of 0.76(95%CI:0.64-0.88)and 0.73(95%CI:0.60-0.87),respectively.The calibration curve and the decision curve analysis showed that the models had good predictive accuracy and clinical practicability.Conclusion Preoperative indicators,including tumor number,PA,WBC,and tumor size,can effectively predict postoperative recurrence in ANHC patients,while tumor capsule integrity,age,and PT are significantly associated with OS.The nomogram models established have good performance and can provide a basis for individualized prognostic assessment.
