Methods The present study is a randomized comparative clinical trial. 607 healthy parous women were randomly allocated into GyneFix IN group (n=302) or TCu 380A group (n=305). IUD was inserted during the menstrual interval by the trained investigators. Follow-up were arranged at 1,3,6 and 12 months after insertion. The discontinuation rates were calculated by life table method.

采用随机对比性多中心临床研究方法，对607例健康经产妇女由经过培训的专人以随机方法于月经间期放置GyneFix IN IUD 320例(GyneFix IN组)及TCu 380A IUD 305例(TCu 380A组)，于放器后1、3、6和12个月随访，以生命表法统计两种IUD的终止情况。

METHODS: In this study, 60 patients were randomized into twogroups to receive either oral Passiflora incarnata (500 mg,PassipyTM IranDarouk)( n = 30) or placebo ( n = 30) as premedication,90 min before surgery.

In a randomized, multicenter trial, 341 patients with moderate or extensive bullous pemphigoid received large doses of high-potency topical corticosteroids -- either topical clobetasolpropionate cream (40 g per day) or oral prednisone (0.5 mg perkilogram of body weight per day for those with moderate diseaseand 1 mg/kg/day for those with extensive disease)-- applied over their entire body.

在此次追踪多中心的试验中，341位中度或广泛性大水疱性类天疱疮患者接受大剂量较强外用皮质肾上腺类脂醇全身治疗──使用外用clobetasol propionate乳剂（40g/日）或者口服prednisone（中度患者0.5mg/千克体重/日，重度患者1mg/千克体重/日）。

Methods 1020 patients (672 male, 348 female, mean age 57.8±2.4 yr) undergoing CAG or PCI were randomized into either the Angioseal group (CAG 380, PCI 120) or the Perclose group (CAG 392, PCI 128). The procedural success rate and occurance of local complications were compared between the two groups. Results Both kinds of devices had a high success rate (Angioseal 94% vs Perclose 96%) and there was no statistical difference between them.

BACKGROUND: In this prospective, randomized, double-blind study, we evaluated whether a very low dose of spinal bupivacaine could be sufficient for safe performance of short perianal surgery.

背景：在这个前瞻性，随机双盲研究中，作者评估了极低剂量的布比卡因實otilde；于安全进行短小的肛周手术是否足够。

Methods: Sixty-four patients undergoing total knee arthroplasty were randomized either to receive a periarticular intraoperative injection containing ropivacaine, ketorolac, epimorphine, and epinephrine or to receive no injection.

METHODS: A total of 140 subjects with bilateral knee OA were randomized sequentially into 4 groups (groups I-IV). Group I received isokinetic exercises; group II received isokinetic exercise and pulse ultrasound for periarticular soft tissue pain; group III received isokinetic exercise, pulse ultrasound, and intraarticular hyaluronan therapy; and group IV acted as the control group.

140名患有双侧膝骨关节炎的患者（Altman分级II级）被连续地随机分配到4个组。I组进行等速运动；II组进行等速运动，同时，伴关节周围软组织痛的患者接受脉冲超声治疗；III组进行等速运动联合脉冲超声及关节内透明质酸治疗；IV组为对照组。

In this randomized,double-blind, controlled study we sought to demonstrate that1% ropivacaine peribulbar block in conjunction with generalanesthesia improves operative conditions and postoperativeanalgesia compared with GA combined with subcutaneous normalsaline injection into the inferior eyelid.

该项随机双盲对照试验是为了证明1%罗哌卡因眼球周围阻滞联合全麻，较眼睑下方生理盐水皮下注射联合全麻，不但能改善手术条件，而且能减轻术后疼痛。

Methods Seventy-five SD rats were randomized into five groups: normal, model, iodine glycerin (20 g/L), high-dose SP (200 g/L) and low-dose SP (100 g/L). The experimental periodontitis rat models were established by ligating molars with steel wire combined with intramuscularly injection of prednisolone (1.25mg, 8 times). Except that the model and normal groups were treated by applying saline, the other groups were treated by applying the corresponding drugs 0.5 mL to the peridentium, tid for 10 days. After treatment, debris index, probe depth and bleeding rate during probing were investigated and the pathological changes of periodontal tissues were also observed.

方法］SD大鼠随机分为正常组，模型组，碘甘油组(20g/L)，舒口散高、低剂量组(200、100 g/L)；采用钢丝结扎牙齿加肌注波尼松龙（l.25 mg/次，共8次）的方法复制大鼠实验性牙周炎模型；药物采用口腔局部涂搽，每次0.5mL，每日3次，10 d为1疗程，模型组与正常组给予等容积生理盐水；检测各组软垢指数、探诊深度、探诊出血阳性例数，并取牙周组织进行病理学检查。
