近年来,随着关节镜器械和技术的不断发展,镜下踝关节韧带修复受到广泛关注。该技术可分为关节镜辅助下伸肌支持带(IER)增强术和关节镜下距腓前韧带(ATFL)修复术。采用关节镜技术治疗慢性踝关节不稳(CAI),ATFL解剖修复被认为是关键步骤然时,是否需要附加IER增强术目前存在争议。有研究报道关节镜下ATFL修复联合IER增强术后的良好结果,代价是显著增加了手术时间和难度。此外,由于IER的解剖起点位于跟腓骨韧带前方10 mm处,1ER增强术并非严格意义上的解剖修复,可能会增加术后关节活动受限的风险。

良性的无神经症状的骨质疏松患者的压缩性骨折本质上是稳定的骨折,常采用非手术治疗。鉴于其治疗方式通常包括佩戴矫形器,本研究比较了刚性支撑、软支撑矫形器和无支撑的治疗效果。60例患者的平均年龄为72.25岁,都是急性一个节段的骨质疏松性压缩性骨折,随机分组后分别佩戴软支撑、刚性支撑和无支撑的矫形器。指导患者持久穿戴,平躺时除外,共八周。主要预后判断为骨折后12周进行Oswestry功能障碍指数（ODI）评分。

BACKGROUND: Metronome guidance is a feasible and effective feedback technique to improve the quality of cardiopulmonary resuscitation(CPR). The rate of the metronome should be set between 100 to 120 ticks/minute and the speed of ventilation may have crucial effect on the quality of ventilation. We compared three different metronome rates(100, 110, 120 ticks/minute) to investigate its effect on the quality of ventilation during metronome-guided 30:2 ***: This is a prospective, randomized, crossover observational study using a Respi Trainer r. To simulate 30 chest compressions, one investigator counted from 1 to 30 in cadence with the metronome rate(1 count for every 1 tick), and the participant performed 2 consecutive ventilations immediately following the counting of 30. Thirty physicians performed 5 sets of 2 consecutive(total 10) bag-mask ventilations for each metronome rate. Participants were instructed to squeeze the bag over 2 ticks(1.0 to 1.2 seconds depending on the rate of metronome) and defl ate the bag over 2 ticks. The sequence of three different metronome rates was ***: Mean tidal volume significantly decreased as the metronome rate was increased from 110 ticks/minute to 120 ticks/minute(343±84 m L vs. 294±90 m L, P=0.004). Peak airway pressure significantly increased as metronome rate increased from 100 ticks/minute to 110 ticks/minute(18.7 vs. 21.6 mm hg, P=0.006).CONCLUSION: In metronome-guided 30:2 CPR, a higher metronome rate may adversely affect the quality of bag-mask ventilations. In cases of cardiac arrest where adequate ventilation support is necessary, 100 ticks/minute may be better than 110 or 120 ticks/minute to deliver adequate tidal volume during audio tone guided 30:2 CPR.

AIM： To characterize whether a glaucoma model with chronic elevation of the intraocular pressure （IOP） was able to be induced by anterior chamber injection of microbeads in ***： In order to screen the optimal dose of microbead injection, IOP was measured every 3d for 4wk using handheld applanation tonometer after a single intracameral injection of 10 μL, 25 μL, 50 μL or 100 μL microbeads （5×10^6 beads/mL; n=6/group） in New Zealand White rabbits. To prolong IOP elevation, two intracameral injections of 50 μL microbeads or phosphate buffer saline （PBS） were made respectively at days 0 and 21 （n=24/group）. The fellow eye was not treated. At 5wk after the second injection of microbeads or PBS, bright-field microscopy and transmission electron microscopy （TEM） were used to assess the changes in the retina. The expression of glial fibrillary acidic protein （GFAP） in the retina was evaluated by immunofluorescence, quantitative real-time polymerase chain reaction and Western blot at 5wk after the second injection of ***： Following a single intracameral injection of 10 μL, 25 μL, 50 μL or 100 μL microbead, IOP levels showed a gradual increase and a later decrease over a 4wk period after a single injection of microbead into the anterior chamber of rabbits. A peak IOP was observed at day 15 after injection. No significant difference in peak value of IOP was found between 10 μL and 25 μL groups （17.13±1.25 mm hg vs 17.63±0.74 mm hg; P=0.346）. The peak value of IOP from 50 μL group （23.25±1.16 mm hg） was significantly higher than 10 μL and 25 μL groups （all P〈0.05）. Administration of 100 μL microbead solution （23.00±0.93 mm hg） did not lead to a significant increase in IOP compared to the 50 μL group （P=0.64）. A prolonged elevated IOP duration up to 8wk was achieved by administering two injections of 50 μL microbeads （20.48±1.21 mm hg vs 13.60±0.90 mm hg in PBS-injected group; P〈0.05）. The bright-field and TEM were used to assess the changes of retinal
