Value of ultrasonography in diagnosing peripheral intraneural vascular anomalies / 中华超声影像学杂志

To evaluate the value of ultrasonography in diagnosing peripheral intraneural vascular anomalies . Methods The ultrasonographic images of 10 patients with peripheral intraneural vascular anomalies confirmed by surgery or pathology were retrospectively analyzed . T he ultrasonographic features were summarized . Results T he ultrasonographic images could not only clearly show the location , involvement and blood supply of peripheral intraneural vascular anomalies , but also determined the classification of them . Ultrasonography showed enlarging nerves ,within w hich tubular structures could be observed ,and the boundary between the vascular malformations and the perineurium was not clear . Abundant arteriovenous blood flow ( arteriovenous malformation) or low velocity venous blood flow ( venous malformation) within the vascular anomalies could be detected by color Doppler examination . Conclusions Ultrasonography is the preferred imaging method for diagnosis of peripheral intraneural vascular anomalies .

The correlation between the sonographic features of papillary thyroid microcarcinoma and high volume lymph node metastasis / 中华医学超声杂志（电子版）

Objective To study the correlation between the sonographic features of papillary thyroid microcarcinoma (PTMC) and high volume lymph node metastasis. Methods Medical records of 463 PTMC patients were reviewed. Cases of all patients are completed with lymph node metastasis identified by histopathology. Sonographic features such as lesion number, lesion size, echogenicity, calcification, envelope and vascularity of papillary microcarcinoma are recorded. Univariate and multivariate analysis was performed to investigating relationship between sonographic features and high volume lymph node metastasis. Results Twenty four patients have high volume central lymph node metastasis (5.2%, 24/463), in univariate analysis,sex(11.2% in male vs 3.4% in female),age(8.3% in<45 years vs 2.4% in≥45 years),calcification(8.3% in micro vs 0.0% in coarse, 3.2% in mixed and 0.7% in non) , extracapsular invasion (9.3% with vs 3.2% without)and size(9.2% in ≥7 mm vs 2.5% in <7 mm)showed significant difference;multiple logistic regression analysis showed that male(OR=3.205,P=0.009),age<45 years(OR=2.923,P=0.031), microcalcification(OR=9.380,P=0.031)and tumor size≥7mm(OR=3.272,P=0.013)is independent risk factor for high volume lymph node metastasis in the central compartment of PTMC. 10 patients have high volume lateral lymph node metastasis(2.2%,10/463),in univariate analysis,age(4.1% in<45 years vs 0.4% in≥45 years),number of lesions(5.3% in multiple vs 0.9% in single)showed significant difference;multiple logistic regression analysis showed that age < 45 years (OR=11.939,P=0.024) and multiple lesion (OR=7.247, P=0.007) is independent risk factor for high volume lymph node metastasis in the lateral compartment of PTMC. Conclusion Sonographic features of primary papillary microcarcinoma of the thyroid has correlation with high volume lymph node metastasis.

Evaluation of correlations between hyperlipidemia and carotid arthrosclerosis manifestations in elderly diabetes patients / 中华老年医学杂志

Objective To evaluate the correlation of hyperlipidemia and carotid arthrosclerosis manifestations on color Doppler ultrasonography and dynamics of elderly diabetes patients. Methods One hundred and fifty elderly diabetes patients and 106 normal subjects were enrolled in the study. The carotid color Doppler ultrasonography and blood sugar, TC, TG, HDL-C, apoB,VLDL, apoA I, apoB were examined and compared between the two group. Results The blood sugar, TC, TG, HDL-C, apoB, VLDL, apoA I, apoB were increased in diabetes patients which were higher than in normal subjects (P
