Objective To explore the value of multimodal MRI combined with digital breast 3D tomography(DBT)in evaluating lymphatic vascular infiltration(LVI)in patients with invasive breast cancer-non special type(IBC-NST)mass type.Methods A total of 102 patients with IBC-NST mass type were divided into LVI group and non LVI group based on whether LVI occurred.The influencing factors of LVI were analyzed by using multivariate logistic regression.Clinical value of multimodal MRI combined with DBT in evaluating LVI in patients with IBC-NST mass type were analyzed by receiver operating characteristic(ROC)curve.Results Multivariate logistic analysis showed that apparent diffusion coefficient(ADC)value,maximum tumor diameter and peritumoral edema were independent risk factors for LVI in IBC-NST mass type(P＜0.05).ROC curve analysis showed that the area under the curve(AUC)of ADC value,maximum tumor diameter and peritumoral edema alone and in combination for LVI in patients with IBC-NST mass type were 0.749,0.655,0.638 and 0.791,respectively.Conclusion ADC value and its combined application model have high efficacy in evaluating LVI in patients with IBC-NST mass type.

Objective To explore the application effect of Interactive continuing nursing intervention model with three subjects and two tracks,which is based on internet and applied to chronic heart failure patients.Methods During January 1 to December 30,2017,110 chronic heart failure patients,who were going to discharge from the Second People's Hospital of Guangdong Province,were selected for this research.Participants were equally divided into control group and observation group with random number table with 55 cases each.Participants were adopted conventional medication and traditional care,while patients in control group were given extra interactive continuing nursing intervention with three subjects and two tracks,which was relied on internet-based cardiovascular disease management platform.Comparing patients' scores of life quality,self-care ability,anxiety and depression degree before intervention and that in 6 months after intervention with Minnesota Living with Heart Failure Questionnaire (MLHFQ),Self Care of Heart Failure Index (SCHFI),Self-rating Anxiety Scale(SAS)and Hamilton Depression Scale (HAMD) respectively.Moreover,6 minute walk test was conducted,simultaneously,the incidence of cardiovascular events was calculated respectively before intervention,3 months after intervention and 6 months after intervention.Results It showed that total scores of MLHFQ,SCHFI,SAS and HAMD for patients in observation group before intervention were (49.05 ± 4.39),(101.57 ±21.04),(58.3 ± 5.2) and (40.1 ± 3.5) points respectively while that for patients in observation group after 6 months intervention were (43.03 ± 6.85),(123.17 ± 18.23),(42.3 ± 4.2) and (24.4 ± 4.3) points respectively.The difference was statistically significant (t =5.49-20.60,all P ＜0.01).In comparison,intervention effect of observation group was better than that of control group,although,the SAS scores of the control group were statistically significant.Furthermore,after intervention,the difference of MLHFQ,SCHFI,SAS and HAMD scores were statistically significant(t =3.48-17.79,all P ＜0.01).Moreover,6 months after intervention,6 minute walk test evaluation showed that there was statistical significance between observation group and control group (~=8.11,P ＜0.05).Besides,The death rate in observation group was lower than that in control group after 6 months intervention (~=6.30,P ＜0.05).Meanwhile,readmission rate after 3 months and 6 months indicates that there was statistical significance between observation group and control group(x2=5.25,6.30,P ＜0.05).Conclusions Interactive nursing intervention model with three subjects and two tracks which based on internet is able to enhance chronic heart failure patients' self-care ability and life quality,decrease the incidence of cardiovascular events and negative emotion of patients.

Objective To investigate the effect of telephone follow-ups on medication compliance of elderly patients with coronary heart disease after percutaneous coronary intervention(PCI).Methods One hundred and sixty elderly patients with coronary heart disease undergoing PCI were randomly divided into control group(n=79)and experimental group(n=81).Conventional treatment with medication and telephone follow-ups per six months were administered to patients in control group after discharging from the hospital.Besides the same treatment as in the control group,8 telephone follow-ups were made within 12 months from discharging and additional follow-ups were performed if their medication compliance was poor.The two groups were compared in terms of medication compliance 12 months since discharging,and cardiovascular adverse events,readmission rates and restenosis rates within 1 year. Results The medication compliance in the experimental group was significantly better than that in the control group.The rates of cardiovascular adverse events,readmission and restenosis within 1 year were all significantly lower than those of control group(all P<0.05).Conclusion Telephone follow-ups can improve medication compliance of elderly patients with coronary heart diseases after PCI and thereby enhance the curative effects.
