Purpose To explore the diagnostic efficiency of ultrasound(US)combined with contrast-enhanced ultrasound(CEUS)in breast lesions and to analyze the related factors affecting the diagnostic accuracy.Materials and Methods From January 2022 to February 2023,the clinical data and ultrasound images of 784 patients who underwent breast US and CEUS examination with definite pathological results were retrospectively collected in the First Medical Center of the PLA General Hospital.The diagnostic efficacy of US combined with CEUS in benign and malignant breast lesions was analyzed,respectively.The independent risk factors for diagnostic errors were analyzed via Logistic regression.Results The sensitivity,specificity and accuracy of US combined with CEUS in the diagnosis of benign and malignant breast lesions were 89.2%,84.4%and 88.7%,respectively.The area under the receiver operating characteristic curve was 0.932.The results of multivariate Logistic regression analysis showed that the diagnosis error rate increased when the lesions were non-mass type(odds ratio,OR=1.927,P=0.047),complex cystic and solid(OR=3.729,P=0.000),and high-enhanced CEUS(OR=1.937,P=0.023),while the diagnosis error rate decreased when the lesions were large(OR=0.688,P=0.004)and with US-detect suspicious lymph node(OR=0.143,P=0.011).Conclusion When the breast lesions are non-mass type,complex cystic and solid lesions and hyper-enhancement,the diagnosis error rate of US combined with CEUS increased.It is necessary to further explore the enhancement patterns of different lesions.

Purpose To explore the correlation between phosphatidylinositol 3 kinase/serine-threonine kinase(PI3K/AKT)signaling pathway and elastic characteristics of breast lesions.Materials and Methods A total of 115 breast lesions were prospectively analyzed in 114 patients who underwent surgery from May 2021 to May 2022 at Chinese PLA General Hospital.Ultrasound and shear wave elastography were performed preoperatively.Immunohistochemical staining was used to detect the expression of PI3K/AKT protein levels in the tissue specimens,and the correlation between the staining results and the elastic parameters of shear wave elastography was analyzed.Results Surgical pathology revealed benign breast lesions in 50 cases and malignant lesions in 65 cases(25 cases with axillary lymph node metastasis).The maximum modulus of elasticity(F=40.47),the average modulus of elasticity(F=45.11),the ratio of elasticity of the lesion to that of the surrounding tissue(F=48.98),the detection rate of"hard ring sign"(χ2=62.25),the expression level of PI3K/p-PI3K(F=15.19,58.95)and AKT/p-AKT(F=46.94,74.21)were found in benign and malignant lesions without axillary lymph node metastasis,malignant lesions with axillary lymph node metastasis(all P<0.05).The expression levels of PI3K/p-PI3K and AKT/p-AKT were positively correlated with the maximum elastic modulus value,the mean elastic modulus value,and the ratio of elasticity of the lesion to the surrounding tissues(r=0.475,0.475,0.451;r=0.533,0.540,0.542;r=0.371,0.402,0.445;r=0.482,0.455,0.545,all P<0.05).Conclusion The expression level of PI3K/AKT in breast lesions is correlated with elastic characteristics,suggesting that it plays an important role in the regulation of elastic characteristics of breast lesions.

Objective To evaluate the impact of standardized health management and treatment on asthma control and the quality of life of the patients.Methods One hundred asthma patients were recruited in our hospital and were assigned to the health management (n=50) or the control group (n=50).The control group subjects were treated with conventional therapy,while those of the heahh management group received standardized asthma management and health education.The control of asthma and the quality of life were evaluated at baseline and six months after the intervention.Student's t test and Chisquare test were used for data analysis.Results At 6 months treatment,the rate of effective control of asthma of the health management group (56％) was higher than that of the control group (22％) (x2=12.15,P＜0.05).In the control group,the activity limitation,asthma symptoms,mentality asthma,the stimulus response,the personal health concerns and the total score of Quality of life were (47.4±5.8),(35.3±6.2),(28.2±4.3),(22.7±3.5),(17.6±3.9),(151.2±14.7),and they were (38.2±4.5),(27.1±4.8),(23.1±5.7),(18.3±4.3),(13.7±4.2),(121.4± 12.6) in the control group,they were all significantly higher in the management group than that of control group(t values were 6.17,4.42,4.98,5.76,5.43 and 6.35,all P＜0.05).Conclusion The standardized health management and the health education can effectively control asthma and significantly improve the quality of the patient's life.

Objective To explore the effect of health education and comprehensive nursing intervention on quality of patients with lung cancer.Methods One hundred lung cancer patients who were treated with chemotherapy from February 2010 to February 2013 in our hospital were selected and assigned to the intervention group (n=50) and the control group (n=50).The participants in the control group received conventional anti-cancer drug and routine primary care,however those of the intervention group additionally obtained health education and comprehensive nursing intervention.The Zung Anxiety Scale (SAS),Depression Rating Scale (SDS) and the core quality of life questionnaire (QLQ-C30) were used to evaluate the quality of life of the patients.Paired samples t test and ANOVA were used for data analysis.Results Differences of age,gender,disease duration,SAS,SDS score and EORTC QLQ-C30 score were not statistically significant between the two groups (all P＞0.05).After the intervention,SAS and SDS scores of the control subjects were 58.8±7.6 and 49.5±10.1 respectively,and SAS and SDS scores of the intervention group were 46.5±7.8 and 37.4±9.2 respectively (t velues were 5.347 and 6.215,respectively; both P＜0.05).Quality of life scores in the intervention group were as followed:general condition 57.2± 18.3,physical fitness 63.0±25.9,mutual affection 67.3±23.3,cognitive score 75.4±28.2,social role 67.7±24.8 and function scores 58.5±22.3.Quality of life scores in the control group were as followed:general condition 47.3±23.0,physical fitness 54.9±26.6,mutual affection 60.4±19.1,cognitive score 66.2±25.8,social role 54.1±26.2 and function scores 49.4±21.5 (t values were 5.725,6.144,5.021,5.702,7.137 and 6.357,respectively; all P＜ 0.05).Conclusion Health education and comprehensive nursing intervention for lung cancer patients may reduce their anxiety and depression symptoms and improve the quality of life.

ObjectiveTo investigate the impact of health education and psychological intervention on quality of life of patients with asthma.MethodsNinety-six patients with bronchial asthma were assigned to the treatment group and the control group. The participants in the treatment group were treated with routine therapy and health education and psychological intervention.Results The awareness of bronchial asthma,self monitoring of health condition,and simple strategies to treat acute or serious asthma were improved in the treatment group. The overall effective rate of the treatment group was significantly higher than that of the control group (93.75％ vs 62.5％,P ＜0.01 ),and forced expiratory volume in one second (FEV1),peak expiratory flow (PEF) and ACT score were significantly improved (all P ＜ 0.01 ).Moreover,episode of bronchial asthma was significantly reduced after the combined intervention (P ＜0.01 ).ConclusionHealth education and psychological intervention may contribute to effective prevention and treatment of asthma,improved quality of life of patients,and reduced family and social economic burden.
