Objective:To explore the application effect of special quality control management for thyroid and breast ultrasound in community hospitals.Methods:This study was a prospective interventional study. From November 2024 to March 2025, the Department of Ultrasound, China-Japan Friendship Hospital conducted special quality control management for thyroid and breast ultrasound in 17 community hospitals in Chaoyang District. Through measures such as standardized training in thyroid and breast ultrasound as well as quality control investigations before and after the training, changes in the qualification rates of ultrasound image storage, report writing, and nodule grading accuracy for thyroid and breast in community hospitals before and after the implementation of this management were compared, A paired t-test was used for statistical analysis. Results:Thyroid ultrasound quality control effects: Image storage qualification rates significantly improved: the qualification rate of image adjustment increased from 62.94%±22.01% to 85.88%±14.17% ( t=6.35, P<0.001), and body markers application rose from 76.47%±4.93% to 95.29%±7.17% ( t=11.14, P<0.001). The qualification rates for nodule sections and blood flow sections both exceeded 95% ( P<0.001). In report writing: the qualification rates for items such as nodule location, measurement, and echo increased by 10%-25%. The description of nodule margins reached 100% ( t=8.79, P<0.001), and the description of echogenic foci features increased from 41.76% to 79.41% ( t=5.46, P<0.001). Nodule classification accuracy significantly improved: The guideline application rate increased from 55.29% to 91.18% ( t=4.84, P<0.001), and the classification correctness rate rose from 54.71% to 69.41% ( t=5.14, P<0.001). Breast ultrasound quality control effects: Overall improvement in image storage qualification rates: body marker application increased from 75.29%±21.54% to 97.00%±65.88% ( t=3.82, P=0.002). The qualification rates for nodule sections and blood flow section imaging both exceeded 94% ( P<0.001). In report writing: the qualification rates for items like nodule location, measurement, and echo increased by 10%-30%. The classification rate of the Breast Imaging Reporting and Data System (BI-RADS) classification rate rose from 68.82% to 98.24% ( t=3.68, P=0.002), and the classification correctness rate increased from 57.65% to 70.00% ( t=2.74, P=0.014). Conclusion:The implementation of special quality control management for thyroid and breast ultrasound is an effective method to improve the quality of ultrasound medical services in community hospitals.

Atypical teratoid/rhabdoid tumor (AT/RT) is a rare malignancy located primarily in infratentorial or subcortical areas with a poor prognosis, and rarely in the lateral ventricle with a very poor prognosis. So far, only 6 cases of AT/RT in lateral ventricle have been reported in China. This article reports the diagnosis and treatment of four children with AT/RT in the lateral ventricle, and discusses the clinical manifestations, differentiation and diagnosis, treatment and prognosis of the disease through literature review, in order to improve clinicians' understanding of the disease and reduce missed diagnosis and misdiagnosis.

Objective:To explore the effect of comprehensive nursing intervention based on time nursing on dangerous behaviors and psychiatric symptoms of schizophrenic patients.Methods:From April 2018 to January 2019, we selected 128 schizophrenic patients admitted to our hospital for research. All patients were divided into observation group and control group with the random number table, 64 cases in each group. Patients of both groups were given routine nursing. On this basis, observation group implemented the comprehensive nursing intervention model based on time nursing. We compared the occurrence of dangerous behaviors, mental symptoms and cognitive function of patients between two groups.Results:Before nursing, there were no statistically significant differences in the occurrence of dangerous behaviors, scores of Positive and Negative Symptom Scale (PANSS) and Montreal Cognitive Assessment (MoCA) of patients between two groups ( P>0.05) . After nursing, the occurrence of dangerous behaviors, scores of PANSS and MoCA of patients in observation group were better than those in control group with statistical differences ( P<0.01) . Conclusions:Comprehensive nursing intervention based on time nursing can reduce the risk of dangerous behaviors of schizophrenic patients, improve their psychiatric symptoms and cognitive function which has high clinical promotion value.
