Three-dimensional ultrasound locatization in endoscopic thyroidectomy for multinodular goiter / 临床耳鼻咽喉头颈外科杂志

OBJECTIVE@#To explore the three-dimensional ultrasound locatization in endoscopic thyroidectomy for multinodular goiter (MG).@*METHOD@#Thirty two patients with MG underwent ET via bilateral areolar approach. Preoperative ultrasonography were used to locate lesions and marked in the 3-D map designed by us. Dur ing ET procedure, surgery skills were adopted to expose inferior pole of thyroid, glands in the area of Berry ligament or (and) upper pole were retained according to the preoperative location map.@*RESULT@#According to the preoperative ultrasonic orientation, 3 lobectomy were performed in 15 cases of unilateral lesions, 12 subtotal thyroidectomy were performed in 17 cases of bilateral lesions, and 5 patients performed unilateral lobectomy add partial thyroidectomy. All patients had successful ET using bilateral areola approach. No conversions to open surgery, no complication occurred, and no nodules were found missing in the postoperative ultrasonography examinations.@*CONCLUSION@#Preoperative ultrasonic orientation and intraoperative operating skills are contributing to a successful ET for MG.

Effect of antifibrotic herb serum on rat hepatic stellate cell proliferation and collagen synthesis / 中国病理生理杂志

AIM: To investigate the effect of Chinese herbs, Ganxianfang(GXF), on rat hepatic stellate cells (HSC) proliferation and collagen synthesis. METHODS: Two types of herb serum, portal venous serum and circumferential venous serum, were prepared from rats infused intragastrically with 16,8,4 times adult dose of GXF decoction. HSC isolated from rat liver were processed with the above sera in vitro . Then we mensurated the radioactivity of HSC admixed with [ 3H]proline and [ 3H]thymine to judge the effect on proliferation and collagen synthesis of HSC. RESULTS: Both two types of serum collected 0 5, 1, 2 h after intragastrical infusion inhibited HSC proliferation ( P 0 05). CONCLUSION: Inhibition of HSC proliferation and decrease of collagen synthesis may contribute to the GXF antifibrotic action.
