Objective： To observe the clinical effect of Acupuncture at Baihui（GV 20）, Sishencong（EX-HN 1） and Anmian [Extra, locates at the midpoint between Yiming（EX-HN 14） and Fengchi（GB 20）] for primary insomnia.

Methods： A total of 112 patients with primary insomnia were randomized into an acupuncture group and a medication group according to the visiting sequence, 56 cases in each group. The acupuncture group was intervened by acupuncture at Baihui（GV 20）, Sishencong（EX-HN 1） and Anmian [Extra, locates at the midpoint between Yiming（EX-HN 14） and Fengchi（GB 20）], and points selected based on syndrome differentiation, while the medication group was by oral intake of zopiclone tablet. The Pittsburgh sleep quality index（PSQI） was measured before and after treatment, and the clinical efficacy was compared after 1 month of treatment. Results： After treatment, subscales of PSQI and global score in the acupuncture group were improved, and intra-group comparisons showed statistical differences（all P〈0.05）; subscales of sleep quality, sleep latency, sleep duration and global score of PSQI in the medication group were improved, showing statistical differences（all P〈0.05）. Inter-group comparison of global and subscales scores of PSQI showed statistical differences（all P〈0.05）. The total effective rate in the acupuncture group was 92.9%, higher than 67.9% in the medication group, and between-group comparison showed a statistical difference（P〈0.05）. Conclusion： Acupuncture at Baihui（GV 20）, Sishencong（EX-HN 1） and Anmian [Extra, locates at the midpoint between Yiming（EX-HN 14） and Fengchi（GB 20）] as the main treatment method can produce a better effect than oral intake of zopiclone tablet.展开更多

Methods： Clinical literature about acupuncture therapy for sleep apnea syndromes was derived from China National Knowledge Infrastructure （CNKI）, Wanfang Academic Journal Full-text Database （Wanfang）, Chongqing VIP Database （CQVIP）, PubMed and Science Direct between the time that databases were created and March 25th,2017. Relevant excel database was established and descriptive studies and association rules were analyzed. Results： The most frequently used point was Lianquan （CV 23） and the most frequently used meridian was the Stomach Meridian. The analysis of association rules showed that the clinical choice of acupuncture points was highly correlated, among which the combination of the highest degree of confidence and the highest degree of support was Shenmen （HT 7） and Sishencong （EX-HN 1）; Lieque （LU 7）, lianquan （CV 23） and Zhaohai （KI 6）. Conclusion： Acupuncture treatment of sleep apnea syndromes has specific selection rules of points, providing certain references for clinical and scientific research.展开更多

The results have been indicated, summed up, simplified, and listed in a table. Ac-cording to these results, authors proposed some hypotheses, such as the first grade of the holographicunits on the extremities, the second grade of the holographic units on the extremities, the holographicunit on the head, etc., which are of significance in the clinical selection of points.展开更多

Acupuncture can improve pulmonary functions in asthma patients and thus treat this disorder. To summarize the status of acupuncture treatment for asthma, we have collected clinical literatures published in the recent 20 years and analyzed the influence of acupuncture on pulmonary functions in asthma patients from the aspects of frequently used points, needling techniques, manipulation and mechanisms to provide references for treating asthma with acupuncture.展开更多

文摘Asthma is a common disease with recurrent onset which severely affects patients＇ quality of life. Acupuncture can improve pulmonary functions in asthma patients and thus treat this disorder. To summarize the status of acupuncture treatment for asthma, we have collected clinical literatures published in the recent 20 years and analyzed the influence of acupuncture on pulmonary functions in asthma patients from the aspects of frequently used points, needling techniques, manipulation and mechanisms to provide references for treating asthma with acupuncture.
