  • Purpose : This study conducted a systematic review and meta-analysis to evaluate the clinical effectiveness of laser acupuncture for each condition using information from laser acupuncture trials registered on clinicaltrials.gov from January 2013 to June 2023. Methods : We quantitatively and qualitatively analysed the results of 16 clinical trials of laser acupuncture whose research results were confirmed. A risk of bias assessment was also carried out to assess the quality of each clinical trial. Results : A meta-analysis including three clinical trials was conducted to evaluate the comparative effectiveness of laser acupuncture and sham laser acupuncture in reducing pain and found that the laser acupuncture group had a statistically significant reduction in pain compared with the sham laser acupuncture group. In addition, 11 of the 13 trials not included in the meta-analysis showed a positive effect of laser acupuncture. Conclusion : Although laser acupuncture has a long history of clinical use and a lot of research, there is still some scepticism due to the lack of a clear mechanism of action and inconsistent reports of clinical effectiveness. In addition, there is a significant lack of systematic reviews of clinical evidence for major disease specific, and ongoing research is needed to establish an objective evidence base for the clinical effectiveness of laser acupuncture.

  • Objectives : The purpose of this study is to research the effects of acupuncturing $BL_{67}$ and $LI_1$ and determine the mechanism of action of acupuncturing $BL_{67}$ and $LI_1$ by measuring the changes of regional cerebral blood flow(rCBF) and mean arterial blood pressure(MABP) in normal rats and ischemic rats. Method : This study researched the effects of acupuncturing $BL_{67}$ and $LI_1$ on the change of rCBF and MABP. To determine the mechanism of action of acupuncturing $BL_{67}$ and $LI_1$, pretreatment with indomethacine and methylene blue was done. Result : 1. Acupuncturing $BL_{67}$ and $LI_1$ significantly increased rCBF and acupuncturing $BL_{67}$ and $LI_1$ induced increase of rCBF was significantly inhibited by pretreatment with indomethacin(1 mg/kg, i.p.), an inhibitor of cyclooxygenase, and methylene blue(10 ${\mu}g$/kg, i.p.), an inhibitor of guanylate cyclase. 2. Acupuncturing $BL_{67}$ and $LI_1$ decreased MABP and there was no significantly change of decrease of MABP on acupuncturing $BL_{67}$ and $LI_1$ by pretreatment with indomethacin and methylene blue. 3. These result suggested that acupuncturing $BL_{67}$ and $LI_1$ might significantly increase rCBF by dilating arterial diameter and mechanism of acupuncturing $BL_{67}$ and $LI_1$ might be mediated by cyclooxygenase and guanylate cyclase. 4. The rCBF was significantly and stably increased by acupuncturing $BL_{67}$ and $LI_1$ during the period of cerebral reperfusion in cerebral ischemic rats, which contrasted with the rapid and marked increase in the control group. Pretreatment with methylene blue significantly decreased rCBF by acupuncturing $BL_{67}$ and $LI_1$ during the period of ischemic state, increased rCBF during the period of cerebral reperfusion. These results suggested that the mechanism of acupuncturing $BL_{67}$ and $LI_1$ might be mediated by guanylate cyclase. Conclusion : Acupuncturing $BL_{67}$ and $LI_1$ can increase rCBF in normal state, and improve stability of rCBF in ischemic state. In addition, we suggested that mechanisms related with acupuncturing $BL_{67}$ and $LI_1$ was more involved in the guanylate cyclase pathway.

  • Objectives : The aim of this study is to evaluate the analgesic effect of electroacupuncture on Jogsamni (ST36) in the collagen-induced arthritis rats and investigate the role played by opioid receptor subtypes $({\mu},\;{\delta},\;{\kappa})$ in the antinociceptive effect of electroacupuncture (EA) In the thermal hyper algesia test. Methods : Immunization of male Sprague-Dawley rats with bovine type H collagen emulsified in incomplete Freund's adjuvant, followed by booster injection 2 weeks later induced collagen-induced arthritis (CIA). The thermal hyperalgesia was evaluated weekly with tail flick latency (TFL). In the fourth week after first immunization, EA stimulation (2 Hz, 0.07 mA, 0.3 ms) was delivered into Jogsamni (5736) for 20 minutes. Analgesic effect was evaluated by using the tail flick latency (TFL) after intraperitoneal injection of normal saline, naloxone, naltrindole and nor-binaltorphimine respectively to CIA rats. Results : The results were as follows; 1. The TFL were gradually decreased in CIA as time elapsed after e immunization of arthrogenic collagen and the maximum value was reached between the third to fifth week. 2. EA stimulation on 5736 inhibited chronic inflammatory pain induced by CIA. 3. The analgesic effect of EA was inhibited by pretreatment of ${\mu}-receptor$ antagonist (naloxone),${\delta}-receptor$ antagonist (naltrindole) and ${\kappa}-receptor$ antagonist (nor-binaltorphimine) respectively. Conclusion : Electroacupuncture has an analgesic effect on the CIA rat and has an antinociception mediated by 8, 5, H receptors.

  • Objectives : This study was performed to choose more effective neuro-protective acupuncture point and to verify the effect of acupuncture in promoting neurogenesis and angiogenesis as a result of its neuro-vasculo-regenerative effect in middle cerebral artery occlusion model in rats. Methods : By TTc staining we chose the most effective acupuncture point with neuro-protection. We randomly divided into four groups: Such as (1) sham group(with sham-operation), (2) sham+acupuncture group(with sham-operation), (3) middle cerebral artery occlusion group, (4) MCAO+AT group. Acupuncture procedure was performed for four days. Total RNA was extracted using TRIzol reagent, according to the manufacturer's instructions, and was purified using an RNAeasy mini kit. Immuno-histochemistry was performed using primary antibody mouse anti-BrdU, NeuN, Dcx, and VEGF. Results : We found that $ST_{36}$ had the more neuroprotective effect than $LI_{11}$ and $SP_3$. The microarray analysis revealed that 54 genes were more expressed neurogenesis pathway in MCAO+AT group compared with MCAO group(fold changes greater than or equal to twofold change). 11 genes were more expressed angiogenesis pathway. And 7 genes were more expressed VEGF pathway. Immuno-histochemistry revealed that cell proliferation, cell migration and cell maturation were increased. Conclusions : This study demonstrated that acupuncture on $ST_{36}$ had neuro-protective and neuro-restorative effect in ischemic brain injuries. And its mechanism might be related to promote neurogenesis and angiogenesis. These results suggest that acupuncture have potential benefits for the treatment of ischemic stroke.

  • Objectives : This study aims to review the actual use of acupuncture manipulation in clinical trials and to discuss the directions of studies, to be conducted in the future. Methods : Through five search engines, clinical trial papers were collected, which had involved the use of acupuncture treatment since 2001 when STRICTA was published. The selected papers were classified based on whether acupuncture manipulation and De-Qi were stated. The comparison status of domestic and foreign, status by year, target diseases, and therapeutic interventions were also investigated. Results : 54 % domestic and 69 % foreign papers mentioned acupuncture manipulation or De-Qi. Among them, acupuncture manipulation was used in 40 % domestic and 53 % foreign papers. There was no significant difference around 2010 when the revised edition of STRICTA was published. The use of acupuncture manipulation was the highest in studies that targeted musculoskeletal disorders. Besides that, the use of acupuncture manipulation was higher in cases where acupuncture was used for therapeutic interventions than it was for basic manipulation or combination therapy. Conclusion : Compared to the importance of acupuncture manipulation and De-Qi, there was actually a smaller number of papers that clearly suggested information on acupuncture manipulation and De-Qi. The reason is considered to be a lack of studies to establish the mechanism and effectiveness of each acupuncture manipulation method and studies that objectified the amount of stimulation incurred by the acupuncture manipulation methods. It is necessary to properly utilize acupuncture manipulation by actively conducting these studies.

  • In the present study, We have investigated the bee venom (BV) and melittin (a major component of BV)-mediated anti-proliferative effects, and defined its mechanisms of action in cultured rat aortic vascular smooth muscle cells (VSMCs). BV and melittin $(0.4{\sim}0.8\;{\mu}g/ml)$ effectively inhibited 5% FBS-induced VSMCs proliferations. The regulation of apoptosis has attracted much attention as a possible means of eliminating excessively proliferating VSMCs. In the present study, the treatment of BV and melittin strongly induced apoptosis of VSMCs. These results suggest that the anti-proliferative effects of BV and melittin in VSMCs should be related with induction of apoptosis. Further study about Influence of BV and melittin upon apoptosis mechanism is therefor thought to be necessary to confirm the above results.
