目的 评价子宫动脉栓塞术治疗子宫肌瘤的近期疗效。方法 89例子宫肌瘤患者，采用Seldinger技术分别作左右子宫动脉主干插管检查和栓塞治疗，栓塞剂采用聚乙稀醇颗粒(PVA)或白芨混合颗粒。结果 72例(80．9％)完成随访，随访时间1～28个月。有94．1％(64／68)的患者月经复常；治疗后瘤体缩小25．2％～76．8％(M=41．3％)。除了术中术后疼痛(65例)和发热(16例)外，有2例因肌瘤坏死行子宫切除术，1例出现卵巢早衰。结论 子宫动脉栓塞术治疗子宫肌瘤的近期疗效满意，远期疗效尚待进一步观察。     

上胸椎骨折手术治疗方法的探讨

目的 探讨上胸椎骨折的特点及治疗。方法 15例病人按AO分型，A型2例、B型10例、C型3例。均经后路切开复位、脊髓减压、长节段内固定、取髂骨植骨融合术治疗。结果 随访18-24个月，后路长节段固定随访时无一例失败，完全瘫的患者9例中有1例神经功能改善I级．不完全瘫的5例均有Ⅲ级改善，1例无神经损伤。结论 上胸椎骨折损伤严重，后路长节段固定技术是一种合理的有效治疗方法。     

白细胞粘附作用对ELISA检测HBsAg干扰现象的探讨

目的 探讨在ELISA检测HBsAg试验中，标本混入WBC后，WBC的粘附现象对试验结果的干扰。方法 观察WBC粘附现象对测定结果的干扰情况，以及血浆中WBC含量与干扰程度的关系，同时采用增加洗涤次数的方法对抗WBC粘附的效果观察。结果 标本混入WBC，WBC在反应板内发生粘附。WBC的中性粒细胞含过氧化物酶对试验结果造成干扰；标本中单位体积WBC含量与WBC的粘附量不成正比，但WBC的有效粘附数与OD值直接相关，粘附量越多，OD值越高；且WBC的粘附经洗涤10次也未能完全洗脱。结论 在ELISA检测HBsAg工作中应注意WBC对试验产生的非特异性干扰，采用多种方法防止WBC的混入。     

Effects of hypertension and type 2 diabetes mellitus on the risk of total cardiovascular events in Japanese patients with hypercholesterolemia: implications from the Japan Lipid Intervention Trial (J-LIT).

Hyperlipidemia, hypertension, and diabetes mellitus (DM) are well-established risk factors for cardiovascular disease. We analyzed the cardiovascular events in hyperlipidemic patients with or without DM who were administered open-labeled simvastatin in groups stratified by blood pressure level using data from the Japan Lipid Intervention Trial (J-LIT). Hyperlipidemic patients with DM (n=6,288) had significantly more cardiovascular events than those without DM (n=33,933). The incidence rates of total cardiovascular events in the Non-DM and DM groups were 15.40 and 25.76 per 1,000 patients for the 6-year period, respectively. The relative risk of total cardiovascular events in the DM vs. the Non-DM group was 1.68, and the relative risk was significantly higher in the DM than in the Non-DM group. The relative risks of total cardiovascular events were significantly higher in DM and Non-DM patients whose systolic blood pressure (SBP) was greater than or equal to 130 mmHg compared to that of Non-DM patients whose SBP was less than 130 mmHg, and in DM and Non-DM patients whose diastolic blood pressure (DBP) was greater than or equal to 80 mmHg compared to that of Non-DM patients whose DBP was less than 80 mmHg. In all groups stratified by SBP and DBP, relative risks of total cardiovascular events were higher in DM patients than in Non-DM patients. For patients with hypercholesterolemia and DM, blood pressure should be strictly controlled in order to prevent both coronary events and stroke. These results are in good agreement with the JNC 7 and the ESH/ESC guidelines for DM patients, which recommended that the SBP and DBP be less than 130 and 80 mmHg, respectively.     

Extracellular matrix remodeling in oral submucous fibrosis: its stage-specific modes revealed by immunohistochemistry and in situ hybridization

BACKGROUND: Oral submucous fibrosis (OSF) is a chewing habit-related pre-cancerous condition of the oral mucosa affecting predominantly south Asians. It is histopathologically characterized by epithelial atrophy and fibrosis of the subepithelial connective tissue. Fibrosis extends all the way into the muscle layer, leading to difficulty in mouth opening. However, the dynamics of extracellular matrix (ECM) remodeling with OSF progression is largely unknown. METHODS: Forty biopsy specimens of OSF and 10 of normal buccal mucosa were examined for expression/deposition modes of eight ECM molecules by histochemistry, immunohistochemistry, and in situ hybridization. RESULTS: In the early stage of OSF, tenascin, perlecan, fibronectin, collagen type III were characteristically enhanced in the lamina propria and the submucosal layer. In the intermediate stage, the ECM molecules mentioned above and elastin were extensively and irregularly deposited around muscle fibers. In the advanced stage, such ECM depositions decreased and were entirely replaced with collagen type I only. Their gene expression levels varied with progression of fibrosis, but the mRNA signals were confirmed in fibroblasts in the submucosal fibrotic areas. CONCLUSIONS: The results indicate that the ECM remodeling steps in OSF are similar to each phase of usual granulation tissue formation. Restricted mouth opening may be a result of loss of variety of ECM molecules including elastin into the homogeneity of collagen type I replacing muscle fibers.     

Two-stage treatment of skeletal Class III malocclusion during the early permanent dentition.

A patient with skeletal Class III malocclusion was treated in 2 phases during the early permanent dentition. In phase 1, maxillary protraction was combined with rapid palatal expansion; in phase 2, fixed appliances were placed. The results were good posttreatment, and, 1 year later, a favorable growth tendency could be observed. This report shows that treatment for a patient with skeletal Class III malocclusion can be started in the early permanent dentition, with very good final results.
