Objective To establish a model that integrates ultrasound features and immunological characteristics for predicting the efficacy of neoadjuvant chemotherapy(NAC)in breast cancer patients.Methods A total of 203 breast cancer patients undergoing preoperative NAC at the Fifth Medical Center of the PLA General Hospital between July 2021 and July 2024 were screened.In line with the inclusion/exclusion criteria,177 patients were included.Data on ultrasound and immunohistochemistry was collected.These patients were divided into pathological complete response(pCR)and non-pathological complete response(non-pCR)groups based on postoperative pathology.Factors with P＜0.0 1 in univariate analysis were evaluated using multivariate Logistic regression.Independent predictive factors were used to construct and validate the ultrasound-immunohistochemical model via Bootstrap.Results The reduction rateof the maximum diameter of lesions,posterior echo attenuation,PR status and HER-2 status were identified as independent predictors of pCR(all P＜0.05).The model proved to be highly accurate and stable.Conclusion The model that combines ultrasound and immunohistochemical features can effectively evaluatep CR after NAC in breast cancer patients.

Objective:To investigate the effect of multi-sensory stimulation therapy on agitation behavior in patients with Alzheimer's disease(AD).Methods:A total of 45 patients with AD hospitalized in the Department of Neurology of Xuanwu Hospital, Capital Medical University, from June 2021 to January 2022 were selected, including 23 cases in the control group and 22 cases in the experimental group. The control group was treated with routine nursing methods, and the experimental group was treated with multi-sensory stimulation. The scores of Cohen-Mansfield Agitation Inventory (CMAI) and Behavioral Pathology in Alzheimer′s Disease Rating Scale (BEHAVE-AD) were compared between the two groups before and after treatment.Results:CMAI comparison showed that after the intervention, the CMAI scores of the experimental group and the control group was 33.14 ± 3.72 and 37.13 ± 7.23 respectively. The difference was statistically significant ( t=-2.34, P<0.05). The total score of "physical non aggressive behavior" and "language non aggressive behavior" in the experimental group were (11.09±2.91), (5.73±2.16), which were lower than those in the control group (13.57±4.33), (8.22±2.71). The differences were statistically significant ( t=-2.26,-3.39, P<0.05). The BEHAVE-AD scores of the experimental group before and after the intervention were (13.14 ± 9.54), (9.50 ± 4.81), in the control group were (11.04 ± 8.34), (10.70 ± 9.81). There was significant difference in BEHAVE-AD score before and after the intervention in the experimental group ( t=2.21, P<0.05), but there was no significant difference compared with the control group ( t=-0.73, P>0.05). "Behavior disorder" of the experimental group improved significantly after the intervention, and the score was (2.41 ± 1.26) compared with the control group (4.48 ± 2.87), the difference was statistically significant ( t=-3.10, P<0.05). Conclusions:Compared with routine nursing, visual + auditory + tactile multi-sensory stimulation can improve the agitation behavior of AD patients, especially non aggressive agitation behavior, which has certain clinical significance and can provide reference for future related research.

Objective:To reduce the occurrence of false alarm of vital signs during the use of ECG monitor by using stress ring to fix the lead wire of ECG monitor. Methods 200 patients who used ECG monitor in our department from March 2018 to February 2019 were intervened by two methods. The control group ( n=100) was connected and observed by routine method. The experimental group ( n=100) was added with lead wire to form "stress loop" on the basis of this method. Methods:The connection and fixation of ECG monitors were carried out. The differences of vital signs, heart rate/rhythm and respiratory false alarm between the two groups during ECG monitoring were compared, and the changes of nurses' workload, Hamilton anxiety score and satisfaction were compared.Results:There were significant differences in heart rate/rhythm and respiratory false alarm between the two groups ( P < 0.05). The scores of anxiety, nurses' workload and satisfaction in the experimental group were significantly improved. Conclusion:During the application of ECG monitor, the lead wire coiled into "stress ring" can effectively reduce the ECG monitor vital signs monitoring center rate/rhythm, respiratory false alarm phenomenon, reduce the workload of nurses, improve the satisfaction of nurses, and reduce anxiety of patients.

With the aggravation of social problems of aging population, the incidence of Parkinson disease is increasing year by year, and the frozen gait symptoms of patients with Parkinson disease seriously affect the safety of the patients. This paper reviews the existing studies at home and abroad, and introduces the pathogenesis, assessment tools and effective nursing interventions of the frozen gait of patients with Parkinson disease so as to provide reference for nursing and rehabilitation of Parkinson disease patients with frozen gait.
