音乐疗法缓解种植牙患者焦虑、抑郁与疼痛的效果观察

目的：观察音乐疗法缓解种植牙患者焦虑、抑郁与疼痛的效果。方法选取医院口腔科就诊的种植牙患者100例,按照患者意愿（是否愿意接受音乐疗法）分为观察组与对照组各50例。对照组予一般治疗,观察组在对照组基础上予音乐疗法治疗。观察、比较2组心率、血压,并对治疗前后2组患者焦虑、抑郁和疼痛进行评估。结果2组进入手术室时心率及血压均有所升高,比较差异无统计学意义（ P﹥0.05）。进入手术室10min后,观察组心率及血压较对照组及本组刚入手术室时有所下降,差异有统计学意义（ P<0.05）。2组治疗前焦虑、及疼痛评分比较差异无统计学意义（P﹥0.05）。观察组治疗后焦虑程度明显低于治疗前且明显优于对照组,差异有统计学意义（ P <0.05）;抑郁及疼痛评分2组比较差异无统计学意义（P﹥0.05）。结论音乐疗法对改善种植牙患者焦虑作用明显,值得临床推广使用。     

Changes in sensorimotor regions of the cerebral cortex in congenital amusia:a case-control study

Perceiving pitch is a central function of the human auditory system;congenital amusia is a disorder of pitch perception.The underlying neural mechanisms of congenital amusia have been actively discussed.However,little attention has been paid to the changes in the motor rain within congenital amusia.In this case-control study,17 participants with congenital amusia and 14 healthy controls underwent functional magnetic resonance imaging while resting with their eyes closed.A voxel-based degree centrality method was used to identify abnormal functional network centrality by comparing degree centrality values between the congenital amusia group and the healthy control group.We found decreased degree centrality values in the right primary sensorimotor areas in participants with congenital amusia relative to controls,indicating potentially decreased centrality of the corresponding brain regions in the auditory-sensory motor feedback network.We found a significant positive correlation between the degree centrality values and the Montreal Battery of Evaluation of Amusia scores.In conclusion,our study identified novel,hitherto undiscussed candidate brain regions that may partly contribute to or be modulated by congenital amusia.Our evidence supports the view that sensorimotor coupling plays an important role in memory and musical discrimination.The study was approved by the Ethics Committee of the Second Xiangya Hospital,Central South University,China(No.WDX20180101GZ01) on February 9,2019.     

儿童人工耳蜗植入术后音乐能力发育研究

目的：探讨儿童人工耳蜗植入术后音乐能力的发展趋势,为人工耳蜗植入儿童音乐能力评估提供临床资料。方法：26例人工耳蜗植入儿童,手术年龄为11～68个月,平均35．6个月;以76例1～24月龄的听力正常婴幼儿作为对照组,平均月龄6．1个月。使用小龄人工耳蜗儿童音乐能力等级量表进行评估。人工耳蜗植入儿童评估分别在开机时,开机后1、3、6、9、12及24个月时进行;听力正常婴幼儿评估分别在1、3、6、9、12及24月龄时进行。结果：人工耳蜗植入儿童的音乐能力得分随人工耳蜗使用时间的延长而显著提高（P〈O．05）,听力正常婴幼儿的音乐能力得分亦随年龄的增长而显著提高（P〈O．05）。经两样本比较的秩和检验,人工耳蜗植入儿童与听力正常婴幼儿在听力年龄为1、3、6、9、12个月时音乐能力得分的差异无统计学意义（P〉O．05）,在听力年龄为24个月时音乐能力得分的差异有统计学意义（P〈O．05）。结论：人工耳蜗植入儿童开机后音乐能力随人工耳蜗使用时间的延长而显著提高,并在开机12个月内呈现快速增长趋势。

Tuba players reproduce a Valsalva maneuver while playing high notes

Playing wind instruments requires expiratory efforts. Blowing low notes on a tuba means a low resistance to expiration while playing high notes requires a strenuous expiratory strain. The resulting high intrathoracic pressure may reproduce a Valsalva maneuver. Ten tuba players were asked to blow medium loud long (15 seconds) notes at three different pitches (low, middle, and high) and to perform Valsalva maneuvers at 10, 40, and 60 mmHg. Blood pressure (BP) was measured continuously with a Finapres® monitor. The four classic phases of the Valsalva maneuver were reproduced with the notes. The expiratory effort produced systolic BP and pulse pressure falls reaching about 24 mmHg with the high note or the Valsalva 60. BP and pulse pressure falls were linearly related to stroke volume reductions. Reflex heart rate (HR) changes were inversely related to BP falls, with maximal increases for the high notes (24 beats/minute) and Valsalva 60 (33 beats/minute). High baroreflex sensitivity was associated with a high HR response. Total peripheral resistance was reflexly elevated to counteract cardiac output reductions. During rebreathing, BP overshoots reached 30 mmHg for the high note and 53 mmHg for the Valsalva 60. Altogether, these findings indicate that blowing notes on a tuba reproduces the cardiovascular changes seen with a Valsalva maneuver with the effects of blowing high notes being close to a classic (40 mmHg) Valsalva maneuver. In addition, the baroreflex sensitivity might be a predictor of the ability to surmount the BP intolerance that could occur during wind instrument playing.

Can antistress music tapes reduce mental stress?

The effects of so-called antistress music tapes on reduction of mental stress were examined using Cox and Mackay's SACL, Japanese edition (J-SACL). Fifty-two subjects were exposed to experimentally induced stressful situations and the J-SACL was administered before and after this stress exposure. The results indicated that: (1) music tapes in general could reduce both the stress and arousal factors of the J-SACL; (2) however, differential effects in stress reduction of antistress music tapes were not demonstrated; (3) stress-reducing effects were more prominent in stress than in arousal factors.
