Objective To investigate the value of high frequency color doppler ultrasound for screening thyroid diseases in physi-cal examination people .Methods The detectable information of thyroid diseases using high frequency color doppler ultrasound in 1 413 physical examination people was analyzed .Results A total of 588 cases of the 1 413 people were detected to have thyroid dis-eases with positive rate of 41 .61% ,and the detectable rate increased with aging .The positive rate of female (349 cases ,54 .96% ) was statistically higher than that of male(239 cases ,30 .72% ) .Within the 588 people ,111 cases were diagnosed as diffused thyroid diseases and 488 cases were diagnosed as thyroid nodules by high frequency color doppler ultrasound .Twenty cases were confirmed to have thyroid carcinoma by pathologic examination ,with 3 males and 17 females .Twelve lesions were less than 1 .0 cm in diameter and were diagnosed as microcarcinoma .The smallest lesion was 6 mm × 5 mm .Conclusion The high frequency color doppler ultra-sound was useful in screening for thyroid diseases ,especially for carcinoma ,and should be used as routine examination item .

Objective To investigate the value of conventional ultrasound combined with contrast‐enhanced ultrasound in qualitative diagnosis of benign and malignant cervical lymph nodes (LNs) .Methods Totally 129 enlarged LNs in 112 cases were performed the 2‐dimensional ,color Doppler ultrasound ,and grey‐scale contrast‐enhanced ultrasound(CEUS)examinations .LNs were divided into the benign group and malignant group according to pathologic results .The aspect ratio ,eccentric medulla or medulla de‐fect ,echo type ,blood supply distribution ,contrast‐enhancement pattern and distribution equilibriuym of contrast agent were com‐pared between the two groups .Results The most of aspect ratio in the benign LNs group were ≥ 2 ,the cortex and medulla were uniform with symmetric increase and without microcalcification ,the blood supple was mainly the non‐blood flow type or hilar type , in contrast‐enhanced ultrasound ,the majority were the early hilar and medullar enhancement ,showing the centrifugally full filling ;the most of aspect ratio in the malignant LNs group were <2 ,medulla was eccentric or loss ,partial of LNs showed the increased parenchymal echo accompanied with cystic lesion and microcalcification ,the blood supply was mainly the peripheral and mixed types ,and the non‐hilar and medulla started enhancement pattern .The ultrasonographic parameters mentioned above were statisti‐cally different between the two groups ,in which the non‐hilar and medulla started enhancement patterns had the highest sensitivity and accuracy for diagnosing malignant LNs ,the positive predictive values of these parameters were higher ,whereas the negative predictive values were lower .Conclusion The conventional ultrasound combined with contrast‐enhanced ultrasonography has a higher practical value in qualitative diagnosis of cervical LNs ;the comprehensive judgment of multiple indicators can increase the differentiating ability for benign from malignant LNs .

Objective To evaluate the renal cortical blood perfusion changes in rabbits with acute renal failure (ARF) with gray scale contrast-enhanced ultrasound, and to explore the relationship between these changes and the blood creatinine (SCr), as well as the blood urea nitrogen (BUN). Methods Rabbit ARF models were established with 50% glycerin injected into the rabbits' thighs. Gray scale contrast-enhanced ultrasound was performed on the day before injection (T_0) and 1, 4, 8, 12 days (T_1, T_4, T_8, T_(12)) after injection. The renal cortex perfusion time-intensity curve (TIC) was analyzed, including parameters like arrival time (AT), time to peak intensity (TTP), amplitude of peak intensity (A) and slope rate of TIC (β) of renal cortex. Meanwhile the SCr and BUN were measured, the correlation between SCr, BUN and parameters were analyzed. Results Compared with the value of T_0, the value of TTP, A, β after injection (T_1, T_4, T_8) were statistically different, respectively (P<0.05), but the differences among T_1, T_4 and T_8 were various. No linear correlation between above parameters and SCr, BUN was found. Conclusion The renal cortical blood perfusion changes can be early observed with gray scale contrast-enhanced ultrasound, but there is no linear correlation between the changes of parameters and SCr, BUN.

Objective To explore the relativity between the changes of 1H magnetic resonance spectroscopy(1H-MRS) in hippocampus and prefrontal lobe and syndrome differentiation of major depression.Methods Sixty patients with major depression(MD) were divided into Group A(phlegm-heat syndrome),Group B(blood stasis syndrome),Group C(deficient fire syndrome) and Group D(cold-dampness syndrome),and other 20 normal controls were selected.The neurochemical abnormalities including the ratios of N-acetylaspartate(NAA)/choline(Cho),NAA/creatine(Cr) and Cho/Cr were measured with three-dimension 1H proton magnetic resonance spectroscopy(3D1H-MRS).Results The ratios of Cho/Cr in white matter of the prefrontal lobe were significant higher in MD patients than that in normal controls(P<0.05);the ratios of NAA/Cr in hippocampus were significant higher in MD patients than that in normal controls(P<0.05).Conclusion There might be the relativity between the neurochemical abnormalities in hippocampus and prefrontal lobe and traditional Chinese medicine syndrome differentiation of major depression.

Methods: Data of TCM indicators (tongue, facial, and pulse diagnostics) and clinical parameters from patients diagnosed with CHD at the Cardiology Department of Shanghai Baoshan Hospital of Integrated Traditional Chinese and Western Medicine, from October 3, 2023 to March 15, 2024, were collected. Important variables were identified using importance screening and correlation analysis with CHD risk factors and laboratory markers. Six machine learning models including logistic regression (LR), decision tree (DT), support vector machine (SVM), k-nearest neighbors (KNN), random forest (RF), and gradient boosting (GB), were applied to evaluate the risk of coronary artery obstruction by combining clinical and TCM data of CHD. Model performance was assessed using metrics such as accuracy, precision, and recall, with reliability validated through ten-fold cross-validation. Results: A total of 288 patients were included in the study. Fifteen clinical risk factors, including body mass index (BMI), myoglobin, and alcohol consumption history, were incorporated into the diagnostic models. The KNN model showed good performance when combining clinical data with tongue and facial data. The SVM model performed well when clinical data was combined with pulse data. Among all the models, the KNN model with 10-fold cross-validation, which integrates the three types of TCM diagnostic data (tongue, face, and pulse) with clinical data, performs the best (accuracy: 0.837, precision: 0.814, and recall: 0.809). Conclusion Incorporating TCM diagnostic data can enhance the accuracy of coronary artery obstruction risk assessment. The KNN prediction model that integrate tongue, facial, and pulse data performs the best and can be recommended as a clinical decision support tool.
