Objective To investigate the effect of health education under Doctor-nurse-therapist Integrated Model on patients after lower limb amputation. Methods 70 patients after lower limb amputation were divided into experimental group (n=35) and control group (n=35). The experimental group received health education under the Doctor-nurse-therapist Integrated Model, while the control group received the routine health education. The success rate of health knowledge, satisfaction to nursing care, activities of daily living (ADL) and time stay in hospital were compared. Results The success rate of health knowledge, satisfaction to nursing care and score of ADL were more in the experimental group than the control group (P<0.05), while the time stay in hospital was less (P<0.01). Conclusion The Doctor-nurse-therapist Integrated Model can make the health education continuous and comprehensive, and it is more effective on patients with lower limb amputation.

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.

Objective:To evaluate the value of CT for differentiating gastric leiomyoma (GLM) from gastric schwannoma (GS).Methods:The clinical and imaging data of 42 patients with GLM (GLM group) and 41 patients with GS (GS group) were analyzed retrospectively. The general information and CT features were compared between two groups. The independent factors for differentiating GLM from GS were obtained by multivariate Logistic regression analysis. The receiver operating characteristic curve (ROC) was used to evaluate the diagnostic efficiency of the model.Results:The proportion of female and age in GLM group were significantly lower than those in GS group: 59.52% (25/42) vs. 85.37% (35/41), (51.83 ± 10.52) years old vs. (58.80 ± 10.63) years old, and there were statistical differences ( P<0.01). The upper part of the stomach rate, irregular shape rate, intraluminal growth rate, ratio of long diameter to short diameter and mild to moderate enhancement rate in GLM group were significantly higher than those in GS group: 71.43% (30/42) vs. 14.63% (6/41), 52.38% (22/42) vs. 21.95% (9/41), 92.86% (39/42) vs. 19.51% (8/41), 1.90 ± 0.55 vs. 1.34 ± 0.28 and 92.86% (39/42) vs. 51.22% (21/41), the cystic degeneration rate, ulcer rate, incidence of tumor-associated lymph node, CT values of venous phase and delayed phase in GLM group were significantly lower than those in GS group: 2.38% (1/42) vs. 26.83% (11/41), 7.14% (3/42) vs. 24.39% (10/41), 2.38% (1/42) vs. 60.98% (25/41), (59.21 ± 9.75) HU vs. (66.22 ± 10.33) HU and (65.02 ± 8.62) HU vs. (76.85 ± 11.89) HU, and there were statistical differences ( P<0.01 or <0.05); there were no statistical difference in the rate of calcification and the CT values of plain scan and arterial phase between the two groups ( P>0.05). Multivariate Logistic regression analysis result showed that the tumor location, growth mode, tumor-associated lymph node and ratio of long diameter to short diameter were the independent factors for differentiating GLM from GS ( OR = 34.385, 25.314, 0.023 and 97.700; 95% CI 2.848 to 415.171, 2.674 to 239.670, 0.001 to 0.637 and 3.113 to 3 066.549; P<0.01 or <0.05); when the model threshold was >0.647, the area under the curve was 0.988 (95% CI 0.934 to 1.000), with a sensitivity of 92.9% and specificity of 97.6%. Conclusions:When the tumor is prone to the upper part of the stomach, intraluminal growth, ratio of long diameter to short diameter >1.28, and the absence of the tumor-associated lymph node, GLM tends to be considered, on the contrary, it tends to be GS. Therefore, CT imaging features have certain value in differentiating GLM from GS before surgery.

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.
