A search on acupuncture Deqi was conducted using four Chinese-language biomedical databases (CNKI, Wan-Fang, VIP and CBM) and PubMed database and using keywords "Deqi" or "needle sensation" "needling feeling" "needle feel" "obtaining qi", etc. Then, a "Modern Literature Database for Acupuncture Deqi" was established by employing Microsoft SQL Server 2005 Express Edition, introducing the contents, data types, information structure and logic constraint of the system table fields. From this Database, detailed inquiries about general information of clinical trials, acupuncturists' experience, ancient medical works, comprehensive literature, etc. can be obtained. The present databank lays a foundation for subsequent evaluation of literature quality about Deqi and data mining of undetected Deqi knowledge.
In our previous paper, we analyzed "Deqi" in book Huangdi Neijing (The Yellow Emperor's Internal Classic) and Nanjing (Canon of Difficult Medical Problems) from "Zhishen"(Treating mentality) and Tiaoqi (Regulating qi). In the present paper, the authors discuss the connotations of "Deqi" and related events in the later ages of the abovementioned two classic books to the later stage of the Qing Dynasty when involves about 20 classical works as Zhenjiu Dacheng ( The Great Compendium of Acupuncture and Moxibustion), Zhenjing Zhinan (Guide to the classics of Acupuncture), Zhenjiu Daquan (A Complete Works of Acupuncture and Moxibustion) etc. from 1) close association between "Deqi" and patients' mental activity; 2) how to wait for arrival of qi if the needling does not induce "Deqi" for the time being; 3) how to identify "qi-arrival" and then, performing suitable manipulations; 4) Deqi and shallow- or deep-needling; 5) putting more emphasis on patients' feeling and reactions, rather than the practitioners perception beneath the needle which is described in book Huangdi Neijing; and 6) not withdrawing the acupuncture needles if qi does not arrive. Generally, in the later ages, the connotations of Deqi are enriched greatly.
To analyze the effect of needling acupoints (bilateral vs unilateral) with De Qi using data collected from 501 primary dysmenorrhea (PD) patients participating in multi-center, randomized, controlled trail. De Qi was defined as at least one of the feelings in soreness, numbness, fullness or heaviness at the acupoints when stimulated with needles. The 501 patients were grouped in 3 groups in terms of De Qi or not De Qi in one side (unilateral) or both sides (bilateral) of the body: bilateral De Qi group, unilateral De Qi group, and non-De Qi group. The abdominal pains were measured using visual analog scale (VAS). In 501 patients, 472 acquired De Qi at unilateral acupoints, 24 De Qi at bilateral acupoint, and 5 had no De Qi at any acupoint. The data of non-De Qi group was excluded as the sample was less than 5% of that in the bilateral De Qi group. There was significant difference in the VAS before and after treatment between unilateral and bilateral De Qi group (P < 0.01). After stratified by acupoints, for the patients needled at Sanyinjiao (SP 6) and Xuanzhong (GB 39), VAS scores in the bilateral De Qi group were larger than those in the unilateral De Qi group (P < 0.05). Bilateral De Qi was possibly superior to unilateral De Qi in enhancing the immediate analgesic effect of needling the acupoints, but no statistical significance was observed on the patients of needling at non acupoint, which preliminarily suggested this immediate analgesic effect was perhaps along meridians.
Although deqi, the phenomenon whereby excitation of Qi in the meridians occurs with needling, is critical to the practice of acupuncture and its efficacy, it is poorly understood. So we investigate the influence of the deqi sensation on the analgesic effects of acupuncture in patients who were enrolled in a randomised controlled trial for the treatment of patients with primary dysmenorrhea, a painful and common condition, and cold and dampness stagnation. Two groups were assessed: a deqi group (undergoing deep needling with thick needles and manipulation, n=17) and a non-deqi group (undergoing shallow needling with thin needles and no manipulation, n=51). The Sanyinjiao (SP6) was needled for 30 min in both groups. Pain scores at baseline, upon needle removal, and at 10, 20, and 30 min after needle removal were evaluated by the Visual Analogue Scale for pain. The deqi sensation was evaluated by the Acupuncture Deqi Clinical Assessment Scale. Patients who experienced a genuine deqi sensation (n=39) were selected for further analysis. Compared with patients in the non-deqi group who experienced deqi (n=25), patients who self-reported deqi in the deqi group (n=14) felt a stronger deqi sensation, experienced soreness and fullness more frequently, felt a greater intensity of soreness, fullness, electric sensation, spreading, and radiating, and experienced larger spreading distances. In those who experienced the deqi sensation in the deqi group, the intensity of the sensation, as well as their degree of soreness and fullness, was negatively correlated with pain reduction. In patients who experienced the deqi sensation in the non-deqi group, deqi intensity was positively correlated with pain reduction, while soreness was negatively correlated with pain reduction. The distance of spreading was not correlated with pain reduction in either group. We found, in SP6 needling of patients with primary dysmenorrhea with cold and dampness stagnation, that a moderate deqi response predicted a prolonged analgesic effect better than a strong deqi response.
To observe the influence of acupuncture needle stimulation-induced sharp pain on the curative effect of acupuncture therapy for primary dysmenorrhea (PD) patients with cold damp stagnation syndrome (CDSS).A total of 87 PD patients with CDSS experiencing abdominal pain (> or =40 mm in visual analogue scale, VAS) were randomly asigned to deqi-expectation group and no-deqi-expectation group which were further divided into deqi-expectation + sharp pain (n = 31), deqi-expectation + no-sharp pain (n = 12), no-deqi-expectation + sharp pain (n = 17), no-deqi-expectation + no- sharp pain (n =27) groups. On the first day of abdominal pain attack, bilateral Sanyinjiao (SP 6) were punctured respectively with thicker needles with deeper insertion for deqi-expectation patients and thin filiform needles with shallow insertion for no-deqi-expectation patients. The needles were manipulated for 30 s with uniform reinforcing-reducing method for all the deqi-expectation patients, which was repeated once again every 10 min during 30 min of needle retention. The VAS was used to evaluate the patients' abdominal pain severity before treatment and 0, 10 min after acupuncture needle withdrawal.Following acupuncture stimulation of SP 6, the VAS scores of menstrual pain at both 0 min and 10 min after withdrawing acupuncture needles were significantly decreased in the deqi-expectation + sharp pain group, deqi-expectation + no-sharp pain group, no-deqi-expectation+sharp pain group and no-deqi-expectation + no-sharp pain group (P<0. 05), and that of 10 min post-needle withdrawal was markedly lower than that of 0 min in the deqi-expectation + sharp pain group ( P<0. 05). No significant differences were found in the VAS difference values at different time-points between deqi-expectation plus sharp pain and deqi- expectation + no-sharp pain groups, and between no-deqi-expectation + sharp pain and no-deqi-expectation + no-sharp pain groups (P>0.05).Acupuncture stimulation of SP 6 has an immediate analgesic effect in PD women with cold damp stagnation syndrome, which was not affected by needling-induced sharp pain, deqi-expectation, and thicker or thinner needle with shallow and deeper insertion.
Background Acupuncture has been demonstrated to be a safe and effective treatment for insomnia in patients without cancer. A lack of evidence, however, supports its application in the treatment of cancer-related insomnia (CRI). Objective To conduct a systematic review and meta-analysis to assess the efficacy as well as safety of acupuncture for alleviating insomnia in patients with cancer. Methods A systematic search was conducted using four electronic databases (PubMed, EMBASE, Scopus and the Cochrane Library) to select publications published in peer-reviewed journals written in English. The OR was calculated, along with their 95% CIs. We assessed heterogeneity using Cochrane Q, I 2 statistics and the appropriate p value. The analysis used RevMan V.5.3. Findings The present meta-analysis comprised 561 individuals from 10 randomised controlled trials (RCTs) across age cohorts. Acupuncture intervention improves Pittsburgh Sleep Quality Index (PSQI) scores and CRI more than control, with a pooled OR of 1.66 (95% CI 1.12 to 2.46), OR of 5.90 (95% CI 2.64 to 13.23) for electroacupuncture, OR of 2.30 (95% CI 1.48 to 3.58) for auricular-acupuncture and 2.72. Acupuncture improved the Insomnia Severity Index (ISI) and CRI more than control approaches, with ORs of 1.31 (95% CI 0.69 to 2.48), 5.29 (95% CI 2.18 to 12.84), 3.17 (95% CI 1.35 to 7.44) and 1.64 (95% CI 1.00 to 2.68). Conclusion The change in PSQI and ISI scores showed that acupuncture moderately improved insomnia in patients with cancer. Acupuncture is safe and effective, enabling subsequent clinical treatments.
Acupuncturists have always paid high attention to deqi (needling sensation) in clinical. However, relationship between deqi and curative effect has not been elucidated yet. In order to have a further understanding on effect of deqi on clinical effect, through study on literature associated with deqi since the establishment of People's Republic of China in 1949, it is held that various factors can influence therapeutic effect of acupuncture treatment, including whether needling sensation appears or not, the speed of deqi, the intensity of deqi, different types of sensations as well as propagated sensation along meridians (PSM). Joint launched multidisciplinary researches should be carried out to reveal the influence principle of deqi on acupuncture effect, and to lay foundations for the further studies on mechanism of deqi.
The paper is a systematic review on the efficacy of acupuncture manipulation on primary dysmenorrhea. Ten medical literatures database at home and abroad were retrieved, including CNKI, VIP, CBM, WANFANG, MEDLINE, Cochrane, CENTRAL, CINAHL PLUS, EMBASE, AMED and PsycINFO, as well as 6 clinical trial registration platforms. All of randomized controlled trials (RCTs) on primary dysmenorrhea treated with different acupuncture manipulations were collected. The data were extracted by two persons. Finally, RevMa 5.3 software was used for statistical analysis. Totally, 5 148 pieces of literature were retrieved and 8 pieces on RCTs were screened with 644 cases included. According to the results of statistical analysis on the total effective rate and other indicators of pain degree, it was showed that the effects of the manipulation with filiform needle, deep puncture with strong stimulation, and specific reinforcing and reducing needling technique were better than those without manipulation applied or with shallow puncture and weak stimulation and even needling technique in the treatment of primary dysmenorrhea. It is believed initially that acupuncture manipulation contributes to the improvement of the therapeutic effects of primary dysmenorrheal, but much higher quality studies are required for the further confirmation.
