放射治疗71例骨转移癌止痛效果分析

目的观察低于常规剂量的2种分割方式治疗骨转移性疼痛的疗效。方法71例恶性肿瘤晚期骨转移患者,总计93处骨转移灶,根据疼痛程度及行动受限程度,采取2种均低于常规剂量的分割方式进行放射治疗,分别为Dm30Gy/10f/2W,Dm30Gy/6f/2W。观察疼痛缓解情况。结果2种分割方式止痛有效率分别为88%、95%。两组间无显著差异性(P>0.05)。与国内多数文献报告的结果接近。结论低于常规剂量的分割方式对转移性骨痛疗效与常规剂量的分割方式的疗效相当,且简便易行。     

Isolated high-frequency jaw tremor relieved by botulinum toxin injections.

Jaw tremor can be seen as a component of various neurological disorders such as essential tremor, Parkinson's disease, dystonia, branchial myoclonus, hereditary geniospasm, task-specific tremor, and Whipple's disease, as well as in normal situations such as shivering, and subclinical physiological jaw tremor. In most of these conditions, the jaw tremor is usually associated with tremor or other abnormal involuntary movements affecting additional body parts, and its frequency is lower than 12 Hz. Schrag and colleagues reported a patient with a high-frequency idiopathic jaw tremor, and they speculated it could be related to orthostatic tremor affecting the masseter muscles. We encountered a similar patient with intermittent rapid focal jaw tremor that was successfully treated with botulinum toxin injections to the masseters.     

强化胰岛素治疗的2型糖尿病患者胰岛素脱离与否相关因素分析

目的比较强化胰岛素治疗的2型糖尿病患者在脱离胰岛素治疗和继续胰岛素治疗时的临床特点,分析脱离胰岛素的相关因素。方法统计66例入院的2型糖尿病患者的患病时间,检测开始胰岛素强化治疗、治疗过程、治疗结束时的糖化血红蛋白(HbA1 c)、体重指数(BM I)、胰岛素用量,观察脱离胰岛素所需时间。结果34例患者脱离胰岛素治疗,32例继续治疗,两组患者在年龄、治疗开始时间、BM I、HbA1 c差异均无统计学意义,而患病时间比较差异有统计学意义(P<0.05),脱离时的胰岛素用量和HbA1 c比继续治疗患者显著减低(P<0.01)。结论患病时间长短是胰岛素脱离与否的重要因素,胰岛素投入量及HbA1 c数值对脱离胰岛素与否有积极作用。     

RNA干扰及其在胶质瘤基因治疗中的应用

RNA干扰（RNA interference。RNAi）是双链RNA（double—stranded RNA，dsRNA）降解特异性靶基因转录出的mRNA。从而抑制靶蛋白表达的现象。自从二十世纪九十年代发现RNAi这一现象以来，RNAi已被广泛应用于研究基因功能、信号转导通路和基因治疗等方面。随着分子生物学、分子遗传学等学科的发展．发现了许多与肿瘤发生、发展和预后密切相关的基因。经过大量临床前期试验表明，针对特异性靶基因的小干扰RNA（short／small interfering RNA．siRNA）治疗胶质瘤是行之有效的。为基因治疗胶质瘤提供了新的思路。[第一段]     

三联药物治疗未破裂异位妊娠的临床研究

目的 :观察甲氨蝶呤(Methotrexate,MTX)、米非司酮(Mifepristron,Ru486)及中药三联用药治疗未破裂型异位妊娠的临床疗效。方法 :对171例未破裂型异位妊娠病人 ,按药物治疗方法不同分为两组进行对照研究 :A组使用MTX注射 +Ru486口服 +中药联合治疗。B组单独使用MTX注射治疗。测定法定期测定两组病人血HCG值以监测血HCG下降情况 ,测量异位妊娠包块三径线值以监测病灶包块缩小情况 ,同时观察临床症状持续时间、副反应发生率及总有效率。结果 :血HCG下降及病灶包块缩小A组较B组明显 ,差异有显著性(p<0 05,p<0 01);临床症状持续时间A组较B组短 ,差异有显著性(p<0 05);副反应发生率两组间无显著差异(p>0 05);A、B两组的总有效率分别为 :95 74%和71 43% ,A组较B组高 ,差异有显著性(p<0 05)。结论 :三联使用甲氨蝶呤、米非司酮及活血化瘀消包块杀胚的中药既有很强的杀胚功能 ,又能消除病灶包块 ,保留生育功能。三联药物联合治疗未破裂异位妊娠具有疗效肯定、安全

Cabergoline compared to levodopa in the treatment of patients with severe restless legs syndrome: results from a multi-center, randomized, active controlled trial.

We report the first large-scale double-blind, randomly assigned study to compare two active dopaminergic therapies for Restless Legs Syndrome (RLS), the dopamine agonist cabergoline (CAB) and levodopa/benserazide (levodopa). Patients with idiopathic RLS were treated with fixed daily doses of 2 or 3 mg CAB or 200 or 300 mg levodopa for 30 weeks. Efficacy was assessed by changes in the IRLS (International RLS Severity Scale) and by time to discontinuation of treatment due to loss of efficacy or augmentation. 361 of 418 screened patients (age 58 +/- 12 years, 71% females) were randomly assigned and treated (CAB: n = 178; levodopa: n = 183) in 51 centers of four European countries. Baseline IRLS total score was 25.7 +/- 6.8. The baseline-adjusted mean change from baseline to week 6 in IRLS sum score was d = -16.1 in the CAB group and d = -9.5 in the levodopa group (d = -6.6, P < 0.0001). More patients in the levodopa group (24.0%) than in the CAB group (11.9%, P = 0.0029, log-rank test) discontinued because of loss of efficacy (14.2% vs. 7.9%, P = 0.0290) or augmentation (9.8% vs. 4.0%, P = 0.0412). Adverse events (AEs) occurred in 83.1% of the CAB group and in 77.6% of the levodopa group. In both groups, most frequent AEs were gastrointestinal symptoms (CAB: 55.6%, levodopa: 30.6%, P < 0.0001). This first large-scale active controlled study in RLS showed superior efficacy of cabergoline versus levodopa after a 30-week long-term therapy. Tolerability was found more favorable with levodopa than with cabergoline.
