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.

Methods 30 patients with chronic respiratory disease were randomly divided into two groups in a double-blind,parallel comparison study,16 patients in the group received Fudosteine tablets,400 mg,po,tid,and 14 patients in the control group received Ambroxol hydrochloride tablets,60 mg,po,tid,both were treated postprandially and for consecutively 7 days.

方法以盐酸氨溴索片为对照药，采用随机双盲、平行对照的试验方法，将30例有慢性呼吸道疾病的患者随机分为两组，即福多斯坦组16例和盐酸氨溴索组14例。福多司坦组给予福多司坦片，每次400 mg，tid，饭后服用；盐酸氨溴索组给予盐酸氨溴索片，每次60 mg，tid，饭后服用。

In contrast, the frequency-domain method transforms the time-frequency convolution into product operation in multiple frequency bands, thus has simple com putation and fast speed. As such, it has become a mainstream method for blind deconvolution.

相比之下，频域方法将时频卷积变换为多个频率段上的乘法运算，运算简单，速度快，因此成为盲解卷的主流方法。

In a prospective, double-blind, placebo-controlled study, patientsundergoing radical retropubic prostatectomy under general anesthesiawere randomly assigned to receive a lidocaine patch or placeboapplied on each side of the wound at the end of surgery.

In the future, double blind, placebo controlled trials comparing the clinical efficacies between sarcosine and an SRI, in combination with genetic studies focusing on the glutamatergic neurotransmission, is suggested.

未来可以进行双盲对照研究比较sarcosine与SRIs的疗效，并收集个案周边血液测试其基因型和治疗前后基因表现、并结合神经影像学研究，以进一步了解麸氨酸神经传导在强迫症之致病因与治疗的意义。

In order to overcome the disadvantages of system performance degradation on the condition of pilot numbers smaller than channel impulse length and bad channel environment in many paths, an improved semiblind channel estimation algorithm based on MLE for OFDM system was presented.

为克服信道冲激响应长度大于导频数时出现系统性能下降，适应存在大量多径的恶劣信道环境，本文对OFDM系统基于MLE的半盲信道估计算法进行了改进。

Recombinant hFSH at a dose of 100 IU on alternate days the spermatogenetic process as evaluated by testicular cytologic analysis and an increase in the number of ejaculated sperm and inhibin B secretion.

此次随机单盲研究中，45位先天性低精子数量（0 x 106/mL），并且血浆卵滤泡刺激素与抑制素B浓度较低的男性患者，接受为期三个月的重组人卵滤泡刺激素50 IU或者100 IU隔日治疗，或者不采用任何治疗措施。

After the dramatic increase in the number of war blinded persons, for whom no pension scheme had been provided and who were obliged to resume their employment, Stelling came up with the idea of using guide dogs.

Subsequently, eight of the subjects with marginal vitamin C status completed an 8-week double-blind, placebo-controlled, depletion-repletion trial with submaximal exercise testing.

随后，八名的边缘学科地位完成维生素C八周的双盲、安慰剂对照、枯竭-补铁试验亚极运动试验。

The post-operative effect and complication rate of endoscopic-assisted transaxillary subpectoral breast augmentation compaired with those of classical subpectoral breast augmentation, there exist no significant difference.

内镜辅助经腋胸大肌下假体植入隆胸术与经典的经腋胸大肌下假体植入隆胸术效果、并发症的发生情况基本相同，盲剥后剥离腔内仍可能存在较多问题、需要内镜下解决。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
