Objective:To analyze the diagnostic performance of contrast-enhanced ultrasound (CEUS) in the diagnosis of papillary thyroid carcinoma (PTC) and related parameters in the diagnosis of cervical lymph node metastasis.Methods:The clinical data of 130 patients who underwent ultrasonography in Ningbo Hospital of Traditional Chinese Medicine from Jan. 2019 to Jan. 2022 were retrospectively analyzed. All patients received contrast-enhanced ultrasonography and postoperative pathological examination. According to the pathological diagnosis of benign and malignant tumors, they were divided into PTC group and benign nodule group. In the PTC group, there were 46 males and 40 females, aging 51.79±5.01 years old, ranging from 32 to 63 years old; In the nodule group, there were 25 males and 19 females, aging 52.05±4.89 years old, ranging from 33 to 64 years old. According to the presence or absence of cervical LNM, they were divided into a metastasis group of 31 cases, 17 males and 14 females; age (51.69±6.14 years), ranging from 36 to 63 years; 55 cases in the non-transfer group, 29 males and 26 females, aging (51.75±6.18) years, ranging from 36 to 62 years. Comparative analysis of different nodule properties, presence or absence of LNM, different lesion diameters in imaging manifestations and time-intensity curve (time-intensity curve, TIC) parameters differences, measurement data between groups were conducted by independent sample t test, count data between groups were compared by χ2. The receiver operating characteristic curve (receiver operating characteristic, ROC) was drawn to evaluate the diagnostic performance of TIC parameters for cervical LNM. Results:The proportion of PTC nodules with low enhancement, irregular enhancement, heterogeneous enhancement, unclear lesion boundary, and perfusion defect (72.09%, 87.21%, 88.64%, 69.77%, 70.93%) was significantly higher than that of benign nodules (38.64%, 11.36%) %, 27.27%, 77.27%, 27.27%) ( χ2=13.67, 70.75, 49.69, 25.92, 18.24, P<0.05) ; PTC nodule peak intensity (peak intensity, PI), TIC area under the curve (area under curve, AUC) was significantly lower than that of benign nodules (14.86±2.11dB vs 23.94±3.51dB, 985.14±105.31dB·s vs 1621.14±182.61dB·s) ; time to peak (TTP) was significantly higher than that of benign nodules ( 44.82±5.01s vs 36.95±4.18s) ( t=18.39, 21.36, 8.94, P<0.05) ; there was no significant difference in mean transit time (MTT) ( P>0.05) ; AUC was significantly higher than that of the non-metastatic group (16.86±2.09) dB vs (13.73±1.42) dB, (1163.54±131.41) dB·s vs (884.59±93.25) dB·s ( t=8.25, 11.46, P<0.05) ; The PI and AUC of PTC patients with lesion diameter ≤1.5 cm were significantly lower than those of patients with lesion diameter > 1.5 cm (11.56±1.94) dB vs (15.93±2.46) dB, (876.97±100.21) dB·s vs (1020.09±125.41) dB·s ( t=8.39, 5.34, P< 0.05), there was no significant difference in terms of TTP or MTT ( P>0.05) ; the AUC of PI in the diagnosis of cervical lymph node metastasis in PTC patients was 0.888 (95% CI: 0.807-0.969), the sensitivity was 90.91%, and the specificity was 77.42%; The AUC for the diagnosis of cervical lymph node metastasis in PTC patients was 0.972 (95% CI: 0.943-1.000), with a sensitivity of 87.10% and a specificity of 96.36%. Conclusion:The CEUS manifestations of PTC nodules are mostly irregular and heterogeneous low-enhancement, and the TIC-related parameters of PTC nodules and benign nodules are significantly different, and TIC-related parameters have good diagnostic efficiency for patients with cervical lymph node metastasis.

The incidence rate of lung cancer ranks second and the mortality rate ranks first in the world. Non-small cell lung cancer (NSCLC) is the main pathological type and is prone to brain metastasis. At present, the main treatment methods of brain metastases from NSCLC include surgery, radiotherapy, chemotherapy, molecular targeting and immunotherapy. Radiotherapy is a common local treatment of brain metastases. With the development of technology and drugs, how to combine radiotherapy with other treatments is a hot topic in clinical research. In this article, advances in radiotherapy for brain metastases from NSCLC were reviewed, aiming to provide reference for the selection of treatment options in clinical practice.

Objective:To analyze the role of home medical and nursing care team in the service system of home disabled elderly.Methods:A total of 100 home disabled elderly managed by our hospital from Jan to Dec 2022 were enrolled,and the home medical and nursing care teams strengthened home rehabilitation nursing services and guidance,health risk guidance,psychological support,and nutrition guidance and intervention.The management results before and after intervention was compared.Results:After intervention,the mastery of health risk management,psychological support and nutritional intervention,and the compliance rate of rehabilitation exercise were higher than those before intervention(P＜0.05).The incidence of pressure injury was lower than that before intervention(P＜0.05).After intervention,the satisfaction rate of the elderly to the work of the home medical and nursing care team was 95%.Conclusion:Home medical and nursing care team plays an important role in the nursing service system of the disabled elderly,and play an important role in the construction of a three-level service health management system of institution-community-home.

Objective:To explore the application of family-centered care model in adult (Intensive Care Unit) ICU patients, so as to provide a reference for future intervention research.Methods:Referring to "Preferred Reporting Items for Systematic Reviews and Meta-analyses Extension for Scoping Reviews (2018) ", research on the application of family-centered care in adult ICU patients was retrieved in PubMed, Cochrane Library, Web of Science, Embase, CINAHL, China National Knowledge Infrastructure (CNKI) , VIP, WanFang Data, and China Biomedical Literature Database. The retrieval time limit was from the establishment of the database to December 31, 2021. An integrated analysis of the included articles was performed.Results:A total of 16 articles were included. The integrated analysis showed that the application forms of the family-centered care model consisted of five aspects, namely, family-centered rounds, interdisciplinary family meetings, flexible family visitation and companionship, family participation in critical care, and family participation in palliative nursing for terminally ill critically ill patients. The interventions involved four aspects of providing training and course education for medical and nursing staff, providing information and care skill guidance for family members, decision support for family members, and psychological support for family members.Conclusions:It is feasible and effective to implement a family-centered care model in adult ICU patients. Relevant departments should formulate corresponding management mechanisms and incentive systems in light of my country's national conditions, and enrich the forms of intervention, so as to promote the application of the family-centered care model among adult ICU patients.
