IntroductionOur objective was to compare the effectiveness and safety of traditional Chinese moxibustion to that of sham moxibustion in patients with chronic knee osteoarthritis (KOA) pain.MethodsWe conducted a randomized placebo-controlled trial involving 110 patients with KOA who met the inclusion criteria. These patients randomly received either active moxibustion (n = 55) or sham moxibustion control (n = 55) at acupoints Dubi (ST 35), extra-point Neixiyan (EX-LE 4), and an Ashi (tender) point three times a week for 6 weeks. Effects were evaluated with Western Ontario and McMaster Universities’ Osteoarthritis Index (WOMAC VA 3.1) criteria at the end of the course of treatment and 3, 12, and 24 weeks after the initial treatment.ResultsThe WOMAC pain scores showed greater improvement in the active treatment group than in control at weeks 3 (P = 0.012), 6 (P <0.001), 12 (P = 0.002), and 24 (P = 0.002) as did WOMAC physical function scores of the active treatment group at week 3 (P = 0.002), 6 (P = 0.015), and 12 (P <0.001) but not 24 (P = 0.058). Patients and practitioners were blinded successfully, and no significant adverse effects were found during the trial.ConclusionsA 6-week course of moxibustion seems to relieve pain effectively and improve function in patients with KOA for up to 18 weeks after the end of treatment. Moxibustion treatment appears to be safe, and the usefulness of the novel moxa device was validated.Trial registrationCurrent controlled trial: ISRCTN68475405. Registered 4 April 2014.

Combined 10.6-mum-650-nm laser acupuncture-moxibustion on acupoint ST35 is safe to use and was effective after 2-wk treatment, but not at the 4-wk assessment, in relieving knee OA pain compared to a nonacupoint sham control. A larger clinical trial to verify our findings is warranted.

Background Polycystic ovary syndrome (PCOS) is one of the most common endocrine diseases for women. Acupuncture is widely used for the infertile female because of it is non-invasive and has fewer side effects, but the powerful evidence for the clinic is still insufficient. Our study intends to explore the effect of manual acupuncture (MA) in the infertile female with PCOS. Methods This study is a randomized, sham-controlled, patient-and assessor-blinded trial and aims to evaluate the effect of MA in women with PCOS and infertility. We will recruit 86 women aged 20–40 years with a diagnosis of infertility with PCOS. Participants will be randomly allocated in a 1:1 ratio to the MA group and the sham acupuncture (SA) group. Both groups will receive real herbal medicine treatment as a basic treatment twice a day for three menstrual cycles, the MA group receive real acupuncture treatment and the SA group received placebo acupuncture treatment (non-penetrating). All patients will receive acupuncture treatment twice per week for three menstrual cycles. The primary outcome is pregnancy rate and secondary outcomes include ovulation rate, sex hormones, insulin resistance index (IRI), PCOS symptoms, and Traditional Chinese Medicine (TCM) syndrome scores. Outcome measures will be collected at baseline, each menstrual cycle, the end of treatments, and six months after the last acupuncture treatment. The present protocol followed the SPIRIT guidelines and fulfilled the SPIRIT checklist. Discussion This study will be conducted to compare the efficacy of MA versus SA. This trial will help to evaluate whether MA is effective in increasing pregnancy and ovulation rates of the infertile female with polycystic ovary syndrome.

The objective of this study was to compare the acupoint infrared radiation spectrums of patients and healthy volunteers to show whether those of coronary heart disease (CHD) patients carry distinctive pathological information. PHE201, using a highly sensitive infrared spectrum detection device applied to the acupoint Neiguan (PC6) and to a control point on 50 CHD patients and 47 healthy adults. A total of 73 wavelength spots were detected. The scanned wavelengths ranged from 1.5 microm to 16 microm, and the scanning spacing was 0.2 microm. The data were automatically recorded in the database of the device for statistical analysis. Infrared radiation intensities of 23 in the 73 detected wavelength spots significantly differed in the CHD patients' Neiguan as compared to those of the healthy subjects (from p=0.048 to p=0.002), while only 12 wavelength spots at a non-acupuncture control point showed significant differences. By the chi(2) test, these differences between Neiguan and the non-acupuncture control point are statistically significant (p=0.033). At 2-2.5 microm, which is related to energy metabolism, the intensity at the CHD patients' Neiguan was significantly lower than that of the healthy adults (from p=0.026 to p=0.017). No difference was observed at the non-acupuncture control point (from p=0.094 to p=0.052). The data suggest that the changes of infrared spectrum at Neiguan in coronary heart disease patients may reflect the distinct pathological changes. This may be the result of hypoactive energy metabolism in the area of the acupoint.

The objective of this paper was to observe the effect of low-level combined- or single-laser irradiation on bradycardia produced by pituitrin in rabbits. A combined-laser apparatus was made. A 10.6-microm CO2 laser and a 650-nm semiconductor laser, transmitted by different optical fibers, converged to output and irradiate on the Neiguan (PC6) acupuncture point in rabbits with bradycardia produced by pituitrin. Thirty minutes after the model was set, the heart rates of the combined-laser Neiguan group made quicker recoveries than those of the model control group, the laser-control group, or the single-laser Neiguan group (P<0.05), and the heart rates of the single-CO2-laser Neiguan group were similar to those of the normal group (P>0.05). However, there were significant differences between the 650-nm-laser Neiguan group and the normal control group (P<0.05). The combined-laser irradiation certainly has a curative effect on bradycardia produced by pituitrin. A single CO2 laser could accelerate the recovery from bradycardia, while single 650-nm-laser irradiation on the Neiguan acupoint does not produce such an effect.

Introduction: This study aims to compare clinical effect between Jade moxibustion and traditional moxibustion, and to determine the clinical effect of Jade moxibustion on knee osteoarthritis (KOA). Methods/Design: This is a 2-parallel-group, randomized controlled trial. A total of 148 subjects with KOA (Kellgren–Lawrence grade II or III) will be recruited and randomized to receive Jade moxibustion treatment or a traditional moxibustion treatment in a 1:1 ratio. Jade moxibustion group: The affected knee of the subjects will be covered with jade kneepad. Traditional moxibustion group: Chosen the ST35, ST34, EX-LE4, SP10 and Ashi points at the affected knee. The subjects will receive treatment three times a week, altogether 12 times in 4 weeks. The main outcomes are WOMAC knee pain score, knee function score and SF-36 quality of life questionnaire changes at the 4th week. Secondary outcomes include WOMAC knee pain score and knee function score, overall clinical efficacy evaluation, medication, safety evaluation at the 2nd, 12th, and 24th week, and cytokines related to osteoarthritis in serum. Discussion: This randomized controlled trial used traditional moxibustion as a control group to provide rigorous evidence for the clinical efficacy and safety of Jade moxibustion in treatment of KOA.
