Objective:To evaluate the sonographic characteristics of primary lymphoma of the thyroid gland and to analyze histo-pathologic findings and other imaging features to improve the diagnostic accuracy of this disease. Methods: We retrospectively re-viewed the records of 20 patients with histologically proven primary lymphoma of the thyroid gland. The clinical, pathologic, sono-graphic, CT, and MRI features were analyzed. Results:Histology revealed non-Hodgkin lymphoma in 20 patients. Ultrasound revealed lateral thyroid lobe disease in 12 cases and the presence of unilateral masses in 8 cases. The main features seen were diffusely enlarged thyroid gland. The lateral or unilateral thyroid lobe was with hypoechoic masses intermingled with echogenic structures. A total of 16 cases showed enlarged lymph nodes, 5 cases showed invasion of trachea, and 1 case involved the trachea and esophagus. Conclusion:Primary lymphoma of the thyroid gland usually presents with clinical and sonographic findings mimicking a carcinoma or benign tu-mor. If clinical features revealed rapidly enlarging neck masses and sonographic characteristics represented by malignant features of Hashimoto thyroiditis, then we should consider lymphoma. However, the final diagnosis depends on histopathology.

Although there is great technological disparity between the best foreign lithotripters and domestic ones, the clinical efficacy of the latter is quite good. In this article, the characteristics, developing status and clinical applications of domestic lithotripters are introduced.

OBJECTIVE:To prepare ambroxol hydrochloride orally disintegrating tablets and to evaluate its quality.METHODS:Mannitol was used as main adjuvant to prepare ambroxol hydrochloride orally disintegrating tablet,the UV spec-trometry was adopted to determine ambroxol content,the disintegration time,taste and dissolution rate were evaluated.RESULTS:The optimal formulation was composed of MCC 50g,mannitol 20g,L-HPC 10g,and NaHCO3 2g;The detected concentration of ambroxol was linear in the range of 0.005～0.030mg/ml(r=0.9 999),the average recovery was 100.50%and RSD=0.71;The prepared tablets disintegrated completely within 30s.CONCLUSION:The orally disintegrating tablets is quick to disintegrate and is as effective as market tablets.

Objective To investigate the effect and mechanism of EGFR in inducing vasculogenic mimicry (VM)formation.Methods Immunohistochemistry was used to detect the expression of EGFR protein and CD34-PAS double staining was used to detect the VM in gliomas paraffin blocks.The migration and VM formation of U87 cell in hypoxic and normoxic groups were detected by transwell and three-dimensional culture.Then we used Western blot to detect the expressions of EGFR,AKT and PI3K protein.Results The positive rate of EGFR expression in VM positive patients was 94.4%,which was significantly higher than that in VM negative patients (71.8%).In hypoxic group,the abilities of migration and VM formation were significantly higher those in normoxic group.The expressions of EGFR,AKT and PI3K were higher in hypoxic group.Conclusion VM formation can be induced by the activation of EGFR/AKT/PI3K signaling pathway.EGFR is very important for VM formation.
