The severity and location of scapulohumeral periarthritis should be identified for determining its treatment method: when the wei exterior is initially invaded by external pathogens for the first time, the location of disease is shallow, therefore, the shallow needling should be performed, which can contribute to diffusing and discharging pathogens of wei exterior. If pathogens had invaded for a long time, they can enter the ying level from wei level, so the acupuncture on ying level should be conducted to discharge the blood stasis and stagnation, thus removing the pathogenic qi and maintaining the healthy qi. If pathogens had invaded for a long time, the meridians and collaterals will be obstructed, and the penetration moxibustion method should be adopted to make the heat penetrate deeply, thereby achieving the effects of warming the meridians and expelling bi. The therapy should be chosen based on syndromes, so meridians can be dredged, and qi-blood can be harmonized, finally the disease will be cured. The precise determination of the location can ensure the success of manipulations. After the nature of disease is identified, targeted methods of acupuncture, bloodletting and fire needling can be performed for treatment of diseases, as a result, "normal physiological activities can be maintained". 展开更多

OBJECTIVE: To observe the effect of acupuncture and moxibustion on insomnia and explore its mechanism. METHODS: One hundred and twenty patients were randomly divided into an experiment group and a control group. Sixty patients in the experiment group were treated once a day with acupuncture at Baihui (GV 20), Sishencong (EX-HN 1), Shenmai (BL 62), and Zhaohai (KI 6) and with moxibustion at Baihui (GV 20) and Sishencong (EX-HN 1). Sixty patients in the control group were acupunctured once a day at Shenmen (HT 7), Neiguan (PC 6), and Sanyinjiao (SP 6).The Pittsburgh Sleep Quality Index (PSQI) was used to compare sleep improvement between the two groups. RESULTS: The total effective rate was 87.7% in the experiment group and 76.3% in the control group. The PSQI scores and the total score were lower after treatment than before treatment in bothgroups. However, the reduction in the experiment group was greater than that in the control group in sleeping quality, time to fall asleep, sleeping disorder, and daytime function (P<0.05). CONCLUSION: Acupuncture and moxibustion at Baihui (GV 20), Sishencong (EX-HN 1), Shenmai (BL 62), and Zhaohai (KI 6) significantly improved insomnia symptoms in the experiment group compared with the control group. 展开更多

OBJECTIVE:To probe the effects of acupuncture reinforcing and reducing methods on the human body.METHODS:Studied acupuncture reinforcing and reducing actions in the ancient literature,based on modern clinical and experimental studies,in combination with experience of acupuncture teaching and clinical treatment.RESULTS:The key to the generation of reinforcing and reducing actions is not the acupuncture reinforcing and reducing methods themselves,but instead the functional state of the patient during the acupuncture.When reinforcing and reducing methods act on the human body,a reinforcing-reducing effect is produced through regulation of Qi,indicating that the production of the reinforcing-reducing effect requires a certain condition.Specifically,acupuncture does not produce the reinforcing-reducing effect under all conditions,but can produce a reinforcing effect in patients with deficiency syndrome and a reducing effect in patients with excess syndrome.CONCLUSION:Reinforcing and reducing methods each have therapeutic effects on both deficiency syndrome and excess syndrome,but a reinforcing method should be selected first for deficiency syndrome and a reducing method should be selected first for excess syndrome. 展开更多
