Nocturnal sleep, respiratory state and Sao2 in 5 healthy men were monitored for 7 hours in Xining (moderate altitude, 2 300m) and at the foot of Animaqin snow mountain (high altitude, 4 660m) respectively. Multi-channel physiological recorder was used for the assessment.The results were as foliows:(l) Total sleep time (TST), sleep efficiency index (SE1) and deep sleep stage 3 and 4 in the subjects transferred to the high altitude remarkably decreased as compared with those at moderate altitude (p< 0.001)....

Nocturnal sleep, respiratory state and Sao2 in 5 healthy men were monitored for 7 hours in Xining (moderate altitude, 2 300m) and at the foot of Animaqin snow mountain (high altitude, 4 660m) respectively. Multi-channel physiological recorder was used for the assessment.The results were as foliows:(l) Total sleep time (TST), sleep efficiency index (SE1) and deep sleep stage 3 and 4 in the subjects transferred to the high altitude remarkably decreased as compared with those at moderate altitude (p< 0.001). The total waking time (TWT), non-deep sleep stage 1 and 2 were longer at high altitude than those at moderate altitute (p<0.05). (2) Periodic breathing (PB) was found in 3 of 5 subjects after entering the high altitude including the one in whom PB as qrequent as 119 with central sleep apnea and the lowest Sao2 of 78% were observed. (3) At moderate altitude, Sao2 during sleeping hours decreased by 4.2% as compared with that during waking hours at night (p< 0.001), while it fell by as much as 11.2% after having reached high altitude (p< 0.001). As compared with Sao2 at moderate altitude, the Sao2 during waking hours at night decreased by 7.4% and that during sleeping time decreased by 14.4% (p< 0.001) after entering the high altitude. These results indicated that (1) sleep aggravated the hypoxemia of highland people; (2) the periodic breathing during sleep should be considered to be a self-protective machanism; (3) hypoxemia led to the disorder of sleep components and the reduction of sleep quality; (4) the frequent periodic breathing or the sleeping apnea would affect the brain function.

在海拔2300m选择健康成年男性5人,急进抵海拔4660m,用多导监测仪分别在两地连续7h监测夜间睡眠、呼吸状态和血氧饱和度变化,进行自身对比。结果发现:(1)急进高海拔后,总睡眠时间、有效睡眠指数、Ⅲ~Ⅳ期深睡眠均较中度高原减少(p<0.01);总觉醒时间、Ⅰ~Ⅱ期浅睡眠高海拔较中度高原增多(p<0.05):(2)急进高海拔后,有3名健康人出现周期性呼吸,其中1名健康者出现周期性呼吸119次,伴有中枢性睡眠呼吸暂停,最低Sao_2为78%;(3)同海拔高度夜间睡眠时与清醒时Sao_2相比较,中度高原下降4.2%,高海拔下降11.2%(p<0.01);高海拔与中度高原夜间清醒时Sao_2相比较下降7.4%,睡眠时下降14.4%(p<0.001)。结果提示:(1)睡眠加重了高原人原有的低氧血症;(2)低氧血症导致睡眠结构的紊乱和睡眠质量的降低;(3)睡眠中出现的周期性呼吸,应视为机体的一种自我保护机制;(4)频发的周期性呼吸或睡眠呼吸暂停将影响大脑机能。

The authors have estimated the coefficient of PCG AR (p) model to be the sample characteristic vector by the Burg algorithm and the theory of the steady random process. One PCG recognition area has been deter mined according to the coefficient. In the present study, 6 cardiac cycles of 3 normal subjects and 4 cardiac cycles of 2 patients with heart diseases were recorded by multi- channel physiological recorder in the clinical trial of the recognition method. The S1 and S2 recognition areas of 6 cardiac cycles of 3 normal subjects were employed as discrimination standard so as to compare and analyze the recognition results of 2 patients with heart diseases. The results showed that in the 5 participants, the S1 recognition area of 3 normal subjects and 2 patients with heart diseases overlapped, though the S2 area did not. This indicated that the S, of 2 patients was normal while the S2 was abnormal. These findings also agree with the physiological implications of sampled experimental data.

作者运用平稳随机过程的理论,采用Burg递推算法估算出的心音AR(p)模型的系数为样本特征矢量,给出1个心音辨识置信区域.作者用多道生理记录仪记录的3例正常人的6个心动周期,2例心脏病患者的4个心动周期作为对此辨识方法进行临床试验的数据.以3例正常人6个心动周期的第一和第二心音辨识置信区域为判别标准,对2例心脏病患者进行对比辨识讨论.结果表明:5例中3例正常人和2例心脏病患者的第一心音辨识区域重合,而第二心音辨识区域不重合.说明这2例心脏病患者的第一心音正常,第二心音不正常.这个结论也符合所采实验数据的生理意义.

Objective To study the effects of treatment with drugs on monoformamidine poisoning.Methods Using multi channel physiological recorder to observe the effects of dopamine and aramine on guinea pigs with monoformamidine(30 mg/kg ip.).Results The heart rate,blood pressure,and myocardiac contraction(dp/dt max) after 2 h of monoformamidine poisoning were (186±18)beat/min,(65±4) mm Hg(1 kPa=7.5 mm Hg) and (374±47) mm Hg/s respectively in dopamine group;(120±36) beat/min, (48±8) mm Hg and (197±70) mm Hg/s in aramine group;(255±29)beat/min,(82±4) mm Hg and (671±184) mm Hg/s in dopamine+aramine group;and (95±22)beat/min,(33±9) mm Hg and (172±92) mm Hg/s in monoformamidine control group.The results in dopamine and combined group were significantly different from thosein control group( P <0.05).Moreover,no extra systole and ST T alteration and death occurred in combined group,and the recovery of Q T interval was shorter than the other groups,so dopamine+aramine showed the most efficacious therapeutic effect. Conclusion Catecholamine drugs may have positive effects on clinical treatment for monoformamidine poisoning.
