Objective To research the clinical therapeutic effect and side effect of gesterol- pingyangmycin cream in interventional therapy of hysteromyoma. Methods 110 cases of hysteromyoma underwent interventional therapy who were divided randomly into two groups:group A with polyvinyl alcohol particle and group B with gesterol-pingyangmycin cream .By percutaneous catheterization in bilateral uterine arteriae using the technique of Seldinger,polyvinyl alcohol particle or gesterol-pingyangmyci cream were injected to blodk up the blood supply of hysteromyoma.The volume of hysteromyomas was measured with B-mode ultrasonography prior and post-treatment.The reaction of post-treatment and the changes of menstrual blood volume were observed . Results The menstruation turned to normal and or menstrual blood volume reduced obviously in two groups , the total effective rate was 95.49 . The volume of hysteromyomas diminished to 45.81 and 51.80 in 3 and 6 months,respectively after treatment.There was significant difference between prior and post-treatment(P

Objective To investigate the efficacy of statin on carotid plaque stability in elderly patients assessed by K trans (the combination of E and F) of dynamic contrast material enhanced (DCE) magnetic resonance (DCE MR) imaging.Methods 37 elderly patients with carotid artery of low echo or mixed echo plaque in carotid artery patches were screened by B type ultrasound.According to the standard of 2011 ESC/EAS guidelines,all patients were divided into two groups:normal level of LDL-C group achieving LDL-C target and high level of LDL C group not achieving target of LDLC.Plaque area and size of lipid-rich necrotic core were measured by 3.0T enhancement magnetic resonance,and K trans was measured by DCE-MR dynamic contrast material enhanced (DCE) magnetic resonance (MR) imaging.and serum hs-C-reactive protein level was detected within 1 week.Results Plaque area,size of lipid-rich necrotic core,ratio of lipoid core over plaque area,K trans and serum level of hs-CRP were less in normal LDL-C level group than in high LDL-C level group [(2.06±0.45) mm2 vs.(3.63±0.62) mm2,(0.52±0.05) mm2 vs.(1.49±0.01) mm2,2 cases (11.8％) vs.14 cases (70.0％),(0.041±0.009) min1 vs.(0.079±0.011) min-1,(1.60±0.27) mmol/L vs.(2.80 ± 0.34),all P＜0.05].Linear regression analysis revealed that there was no significant correlations of K trans with the size of lipid necrotic core (r=0.19,P＞0.05) and hs-CRP (r=0.23,P＞0.05).Conclusions Dynamic contrast material enhanced (DCE) magnetic resonance (MR) imaging is a quantitative method assaying atheromatous plaque components; K trans may be a new indicator to measure the stability of plaques; Statin can stabilize plaques through inhibiting the proliferation of Vasa vasorum in plaque angiogenesis,anti-inflammatory and reducing the size of lipidrich necrotic core.

Objective: To explore the clinical significance of metastasis of lymph nodes between sternocleidomastoid and sternohyoid muscle (LNSS) in papillary thyroid cancer (PTC). Methods: A total of 175 patients with PTC who underwent thyroidectomy with LNSS dissection were retrospectively analyzed. Univariate and multivariate Logistic regression analyses were used to determine the independent risk factors for LNSS metastasis in PTC. Results: The rate of detectable LNSS was 70.9% (124/175) and metastasis rate was 7.4% (13/175). Of 13 cases with LNSS metastasis, 10 with the coexistence of cervical lymph node metastasis. Univariate Logistic regression analysis showed that multiple focal cancer, tumor located in the lower pole of thyroid, belt-shaped muscle invasion, lateral cervical lymph node metastasis, cN+ , the number of cervical lymph nodes with metastasis and the number of lymph nodes with metastasis in level Ⅳwere the risk factors for LNSS metastasis (P<0.05). Multivariate Logistic regression analysis suggested that tumor located in the lower pole of thyroid and the number of cervical lymph nodes with metastasis >6 were the independent risk factors for LNSS metastasis (P<0.05). Given the number of cervical lymph nodes with metastasis as a predictor for the LNSS metastasis, the sensitivity was 92.3%, the specificity was 66.7% and the accuracy rate was 68.6%. Conclusions LNSS metastasis is commom in PTC, with a metastasis rate of 7.4%. PTC in the lower pole of thyroid and the number of cervical lymph nodes with metastasis > 6 are independent risks for LNSS metastasis.
