Objective To assess the values of automated breast volume scanner (ABVS) for differentiating of benign and malignant breast masses.Methods A total 174 breast masses in 148 patients were subjected both to conventional handheld B-mode ultrasound (HHUS) and ABVS examinations.The masses were defined as five categories of benign,probably benign,equivocal,probably malignant,and malignant with each method.The results of ABVS and HHUS were compared with pathology.By using the definitive diagnosis and the five levels of suspicion categories,receiver operating characteristic (ROC) curves were drawn to evaluate their diagnostic results.In addition,the diagnostic accuracy for breast masses of futures including retraction phenomenon and hyperechoic rim in coronal plane of ABVS was evaluated.Results The area under the ROC curve of ABVS (0.927) was larger than that of HHUS (0.903) (Z =2.256,P =0.024).The specificity and the positive predictive values both reached to 100％ and false positive rate was 0 with retraction phenomenon,and the specificity and the negative predictive value were 88.89％ and 94.51％ respectively with hyperechoic rim in coronal plane of ABVS.Conclusions ABVS plays an important role in the clinical practice.The retraction phenomenon and hyperechoic rim of breast masses in coronal plane of this new modality have high specialty for differentiating malignant from benign breast masses.

Objective:To explore the effect of quantitative muscle strength training on postoperative rehabilitation of patients with lumbar disc herniation.Methods:From July 2018 to December 2019, the convenience sampling method was used to select 149 patients with lumbar disc herniation who were admitted to a ClassⅢ hospital for lumbar fusion as the research objects. Patients were divided into the control group (74 cases) and the experimental group (75 cases) according to admission time. The scores of the Oswestry Disability Index and the Japanese Orthopaedic Association (JOA) Low Lumbar Pain Scale before and after the intervention were compared between the two groups. In the end, 71 patients in the control group and 70 patients in the experimental group completed the study.Results:The score of the Oswestry Disability Index after intervention in the experimental group was (15.04±3.26) , which was lower than (17.25±3.48) of the control group, and the difference was statistically significant ( t=3.890, P<0.01) . The JOA Low Lumbar Pain Scale score of the patients in the experimental group after intervention was (23.32±2.86) , which was higher than (21.64±2.72) of the control group, and the difference was statistically significant ( t=3.575, P<0.01) . Conclusions:Quantitative muscle strength training is simple and easy for patients to master, which can improve the postoperative rehabilitation effect of patients with lumbar disc herniation.

Objective:To explore the effects of multifunctional indwelling needle application on the fixation of indwelling peripheral venous needle in children.Methods:Totally 216 children receiving transfusion in the transfusion room of a Class Ⅲ Grade A hospital from June 2018 to March 2019 were selected and divided into the control group ( n=107) and the experimental group ( n=109) according to the random number table. The indwelling needle of children in the experimental group were fixed with the indwelling needle application, while the indwelling needle of children in the control group were fixed with the transparent sticker provided together with the needle. The indwelling time of the indwelling needle, prolapse or displacement of the indwelling needle, curling application, skin damage and residual adhesive tape in the two groups of patients were observed, and the compliance with intravenous infusion and family satisfaction were compared between the two groups. Results:The indwelling time of the indwelling needle of the children in the experimental group was longer than that of the control group; the incidence of indwelling needle prolapse or displacement, curling application, skin damage and residual adhesive tape of the experimental group were lower than that of the control group; the compliance and family satisfaction scores of the experimental group was higher than that of the control group, and the differences were statistically significant ( P<0.05) . Conclusions:The multifunctional indwelling needle application is strongly firm, which can reduce skin damage, prolong the indwelling time of the indwelling needle, and improve the compliance of the children and the satisfaction of family members. It is recommended in the clinical care of children.

Objective:To explore the effects of post level management and secondary performance distribution in the Central Supply Service Department.Methods:From January 2019, the job categories, job labor intensity, technical risk level, division of professional staff, specialist training, job description revision, job capability and other aspects of all staff ( n=67) of Central Supply Service Department of the First People's Hospital of Shangqiu, Henan were set up, and the competitive employment mechanism was applied. Based on the total amount of performance issued by the Nursing Department according to the total number of people in the disinfection supply center, the scientific design and implementation of post performance secondary assessment distribution and post promotion were carried out according to post workload, work quality, technical research, service satisfaction and so on. Results:The difference in the results of comprehensive skills assessment of nurses before and after the performance of secondary assessment and distribution management was statistically significant ( P<0.05) . The difference of job satisfaction of disinfection and supply center among different departments was statistically significant ( P<0.05) . There was statistical significance in the comparison of quality control defects in quality control examination of department ( P<0.05) . In the democratic evaluation of staff, 43 were very satisfied with the performance distribution, 3 were dissatisfied. The content of dissatisfaction was the coefficient in lactation has no difference from other posts. Conclusions:The implementation of the post level management and secondary performance assessment in the Central Supply Service Department has stimulated the potential of nurses at all levels, aroused their enthusiasm for work, and set up goals for everybody. All staff participating in the management improved the work efficiency and quality, guaranteed the nursing safety and the work operation, achieving the satisfactory effect.
