Objective: To explore the relationship between acupoints and meridians.

Methods: Researches were performed on 45 healthy people under the same conditions. The diffuse light intensity of the Pericardium meridian and its surrounding areas were measured before and after warming moxibustion on three acupoints [Shimen (RN5), Qihai (RN6), and Yinjiao (RN7)] of Ren meridian below umbilicus in the same way. Then two sets of data of each sample were used for statistics and analysis, as well as the three-dimensional distribution figures. Statistical definition of probability value was used to evaluate the effect made by moxibustion.

Results: After moxibustion, the diffuse light intensity presented significant changes in 25 samples (P<0.05), enhanced in 15 people (P<0.05) and decreased in 10 (P<0.05). It was consistent with the classification by questionnaire interviews of somatotypes. In addition, diffuse light changed more obviously on Pericardium than non-meridian areas. It was distinct in the three-dimensional distribution figures.

Conclusions: Diffuse light changes happened in entire measure sites demonstrated that acupoints of Ren meridian moxibustion could affect the light propagation of wrist, especially on the Pericardium meridian. It gave an expression to meridians interconnection as said in the Chinese medicine theory. The two classifications made by light propagation changes were experimental corroboration of that personal physical differences affected the manipulation of Chinese acupuncture and moxibustion treatment. These above provided some implications or new directions to future meridian researches.

Objective: To observe the effects of the "Zhibian" (BL54)-toward-"Shuidao" (ST28) acupuncture on key regulatory factors during mitochondrial apoptosis of testicular tissue in asthenozoospermia mice, and explore the potential mechanism of the protective effect of acupuncture on reproductive function.

Methods: Thirty C57BL/6 male mice were randomly divided into a blank group, a model group and an acupuncture group, 10 mice in each group. In the model and the acupuncture groups, the intraperitoneal injection of cyclophosphamide (30 mg•kg•d) was delivered for 7 days to prepare the asthenozoospermia model.

Background: Postoperative nausea and vomiting (PONV) is the most common complication following general anesthesia. Currently, pharmaceutical therapy is the primary method of treatment, but it has reached a plateau, and it is accompanied by inherent adverse reactions and high costs. Stimulation of the wrist acupuncture point PC6 is recommended as an effective means of preventing PONV.

Background: Amphetamine-type stimulant (ATS) abuse is strongly associated with an elevated risk of HIV infection and transmission. Antiretroviral therapy (ART) serves as the primary approach for managing HIV infection and AIDS progression. However, ATS abuse diminishes the efficacy of ART in HIV/AIDS patients, amplifying the vulnerability to immunological non-response (INR) and ultimately increasing the incidence rate and mortality of opportunistic infections.

November 2024

Department of Urology, Princess Alexandra Hospital, University of Queensland, Brisbane, QLD, Australia.

Background And Objective: Despite the growing popularity of acupuncture for sexual dysfunction (SD) in the Western world, many clinicians struggle to understand the exact therapeutic mechanism of acupuncture which is based on traditional Chinese medicine (TCM). This study aims to describe the fundamentals of acupuncture theory from TCM perspectives and its relevance to SD; evaluate the current state of acupuncture research within literature evidence; and critically analyze its therapeutic effects in premature ejaculation (PE), erectile dysfunction (ED), and female SD.

Methods: All published English-language SD clinical studies treated by acupuncture were searched in PubMed from database inception to 1 April 2024.
