Evaluation of thyroid hemangioma by conventional ultrasound combined with contrast-enhanced ultrasound: a case report and review of the literature.

Primary thyroid hemangioma is an extremely rare clinical disease. Only 31 cases have been reported to date according to a PubMed search, and most were postoperatively diagnosed by pathologic examination. Ultrasonography is the first-line imaging modality for thyroid disease screening.

Role of shear wave elastography in the evaluation of the treatment and prognosis of supraspinatus tendinitis.

Background: Supraspinatus tendinitis recurs easily after treatment. One of the main reasons is the lack of objective tools for the efficacy evaluation. Shear wave elastography (SWE) can quantitatively analyze the tissue elasticity of region of interest by measuring the Young's modulus (YM) value.

Value of superb micro-vascular imaging in predicting ischemic stroke in patients with carotid atherosclerotic plaques.

Background: Unstable carotid atherosclerotic plaques are prone to cause ischemic stroke. Contrast-enhanced ultrasound (CEUS) is the primary method of assessing plaque stability, but CEUS cannot be a method for screening for unstable plaque. The emergence of superb micro-vascular imaging (SMI) offers the possibility of clinically screening for unstable plaque.

Studies of Superb Microvascular Imaging and Contrast-Enhanced Ultrasonography in the Evaluation of Vascularization in Early Bone Regeneration.

Objective: The aim of this study was to investigate value of superb microvascular imaging (SMI) and contrast-enhanced ultrasonography (CEUS) in evaluating the neovascularization of early bone regeneration.

Methods: Twenty-five Sprague-Dawley male rats were implanted with recombinant human bone morphogenetic protein-2/calcium phosphate cement (rhBMP-2/) in the muscle space of the left hind limb near the femoral head to establish the rat model of intramuscular ectopic osteogenesis. Ultrasonography and pathologic analysis were performed on the 3rd, 7th, 14th, 21st, and 28th days after modeling.

[Simultaneous determination of ephedrine hydrochloride, D-pseudoephedrine and amygdalin in xiao'er pingchuan qutan granule by HPLC].

Objective: To establish an HPLC method for the determination of ephedrine hydrochloride, D-pseudo-ephedrine and amygdalin in Xiao'er Pingchuan Qutan granule.

Method: Pheny ether chromatographic column (4.6 mm x 250 mm, 5 microm) was adopted, with acetonitrile-0.

[Evaluation on preparation process of brevisapin colon-specific tables and its in vitro release].

Objective: To prepare the new traditional Chinese medicine preparation--pH-dependent brevisapin colon-specific tablets, and investigate its in vitro release, in order to discuss the feasibility of preparing colon-targeted traditional Chinese medicines.

Method: With scutellarin, the active ingredient in brevisapin, as the evaluation index, coating prescriptions of the preparation was screened. The in vitro release determination method was adopted to detect the in vitro release performance of the preparation.
