Effects of Long-term Sleep-deprivation on Rats′Learning and Memory Behavior and Neurotransmitters in Hippocampus and the Effects of Prevention of Electro-acupuncture on the Sishencong Acupoints / 中山大学学报(医学科学版)

[Objective]To investigate the effects of continuous long-term sleep deprivation on rat's behavior,memory and neurotransmitters in hippocampus,as well as determine the effects of prevention of electro-acupuncture.[Method]We used multi-platform water environment to make the rat model of insomnia.The experiment was divided into two sections.Sec-tion one:thirty rats were divided into 5 groups(six rats each group):tank control group(TC),sleep-deprived for continu-ous 7 days group(SD group),three days of recovery after SD group(3d after SD group),six days of recovery after SD group (6d after SD group),eleven days of recovery after SD group(11d after SD group).The term of recovery refers to normal feed-ing and sleeping when rats return to cages after sleep-deprivation.The open-field test was performed following the end time of each group experiment and then the rats were perfused and fixed.Section two:Eighteen rats were divided into three groups (six rats each group):tank control group(TC),sleep-deprived for continuous 7 days group(SD group),sleep-deprived rats treated with electro-acupuncture group(SD+EA group).Rats of SD group and SD+EA group were deprived sleep for con-tinuous 7 days. During the period of sleep deprivation,the rats of SD+EA group were treated with electro-acupuncture 20 minutes every morning.At the end time of experiment,rats were tested by the Morris water maze and then perfused and get specimens.[Results]Section one:the statistical analysis of outcome of open-field test showed:as compared to the TC group,the scores of rat's horizontal movement and vertical movement were significantly fewer in the SD group(P<0.05).Af-ter 3,6,or 11 days recovery of sleep,the scores increased significantly as compared with SD group(P<0.05). Although, the outcome of open-field test in the 3d after SD and 6d after SD groups had the significant difference with TC group(P<0.05),there was no different between the 11d after SD group and TC group(P>0.05).The quantitative analysis of gamma aminobutyric acid(GABA)expression in the hippocampus showed:the SD group shows lower level of GABA when com-pared to the TC group(P<0.05).After 3 days or 6 days of recovery,the expression of GABA is higher than the SD group(P<0.05),and similar to the TC group(P>0.05).In the 11days after SD group,the expression of GABA declined as compared to the TC group and the 6d after SD group(P<0.05).Section two:In the Morris water maze experiment,when compared to the TC group and the SD+EA group,the escape latency period was significantly prolonged and the times of across the plat-form were significantly reduced in the SD group(P<0.05).On the contrary,there were no statistical differences in the escape latency period or the across platform times between the SD+EA group and the TC group(P>0.05).The results of serotonin(5-HT)and GABA in the hippocampus showed:the 5-HT level in the SD group was no significant difference as compared to the TC group and the SD group on 5-HT level,while the 5-HT level in the SD+EA group was reduced as compared to the TC group(P<0.05). In the opposite,the GABA level in the SD group was decreased as compared to the TC group(P<0.05),while the SD+EA group and the TC group appear similarly level(P>0.05).[Conclusions]The effect of 7 days'contin-uous long-term sleep-deprivation may lead to the reduction in the ability of learning and memory behavior of rats.Our results is different with 4 days'continuously sleep-deprivation which was reported on the rats'expression of GABA and 5-HT. Electro-acupuncture stimulating the Sishengcong Acupoints seems preventing the harming of long-term sleep-deprivation on the ability of learning and memory,which probably is through adjusting the disorder of central neurotransmitter expression caused by sleep deprivation.

Analysis on the adverse events of cupping therapy in the application / 中国针灸

The deep analysis has been done on the cases of adverse events and common injury of cupping therapy encountered in recent years in terms of manipulation and patient's constitution. The adverse events of cupping therapy are commonly caused by improper manipulation of medical practitioners, ignoring contraindication and patient's constitution. Clinical practitioners should use cupping therapy cautiously, follow strictly the rules of standard manipulation and medical core system, pay attention to the contraindication and take strict precautions against the occurrence of adverse events.

Electroacupuncture treatment of chronic insomniacs / 中华医学杂志(英文版)

<p><b>BACKGROUND</b>Due to the quick rhythm of life and work pressure, more and more people suffer from sleep quality problems. In this study, we investigated the effect of electroacupuncture on sleep quality of chronic insomniacs and the safety of electroacupuncture therapy.</p><p><b>METHODS</b>Four courses of electroacupuncture treatment were applied to 47 patients. With pre-treatment and post-treatment self-control statistical method, Pittsburgh sleep quality index (PSQI) scores were used for evaluating sleep quality. Polysomnogram was used for detecting insomniacs' changes in sleep architecture. The safety of electroacupuncture was evaluated by monitoring the self-designed adverse events and side effects during treatment and post-treatment.</p><p><b>RESULTS</b>Electroacupuncture considerably improved insomniacs' sleep quality and social function during the daytime. Electroacupuncture had certain repairing effect on the disruption in sleep architecture. At the same time, electroacupuncture prolonged slow wave sleep (SWS) time and relatively rapid eye movement sleep (REM sleep) time. There was no hangover, addiction or decrements in vigilance during the daytime (incidence rate was 0). However, insomnia rebound rate was about 23% within one month.</p><p><b>CONCLUSIONS</b>These results suggest that electroacupuncture has beneficial effect on sleep quality improvement in the patients with chronic insomnia, which may be associated with repairing sleep architecture, reconstructing sleep continuity, as well as prolonging SWS time and REM sleep time. Electroacupuncture treatment for chronic insomnia is safe. Therefore, electroacupuncture therapy could be a promising avenue of treatment for chronic insomnia.</p>

Analysis on adverse effects of acupuncture in clinical practices / 中国针灸

Aiming at raising awareness of preventing adverse effects of acupuncture in clinical practices, such cases were studied from the angle of therapy methods, the factors of patients constitution and practitioners. The findings showed that adverse physical and chemical effects of acupuncture increased in modern times because of multifactorial reasons, for instance, the introduction of modern medicine, the differences of individual constitution and the practitioners. This suggests that to decrease adverse cases acupuncture practitioners should be an expert not only in traditional Chinese medicine, but also in western medicine, such as anatomy, and pharmacology.

<p><b>OBJECTIVE</b>To observe the clinical therapeutic effect of acupuncture regulating "double vitality " for treatment of insomnia, and to enrich the therapeutic principle and the idea of acupoint selection.</p><p><b>METHODS</b>Thirty-four cases of insomnia were selected. According to the therapeutic principle of regulating the primary vitality and calming the heart vitality, the acupoints on the Governor Vessel and the Bladder Meridian, Shenting (GV 24), Baihui (GV 20), Xinshu (BL 15), etc. were alternatively selected for regulating the primary vitality, and the points on the Heart Meridian and the Pericardium Meridian, Shaohai (HT 3), Shenmen (HT 7), Neiguan (PC 6), etc. were selected for calming the heart vitality. The main symptoms and the syndromes of insomnia were assessed and analyzed.</p><p><b>RESULTS</b>After treatment for 4 courses, the total effective rate was 88.2%, and the time falling asleep was significantly shortened (P < 0.05) and the sleeping time was prolonged (P < 0.05), and also the syndromes induced by insomnia were significantly improved (P < 0.01).</p><p><b>CONCLUSION</b>Acupuncture for regulating "double vitality" can significantly improve the sleeping quality of the insomnia patients and the complications.</p>
