ABSTRACT The existence of point specificity in acupuncture is controversial, because many acupuncture studies using this principle to select control points have found that sham acupoints have similar effects to those of verum acupoints. Furthermore, the results of pain-related studies based on visual analogue scales have not supported the concept of point specificity. In contrast, hemodynamic, functional magnetic resonance imaging and neurophysiological studies evaluating the responses to stimulation of multiple points on the body surface have shown that point-specific actions are present. This review article focuses on clinical and laboratory studies supporting the existence of point specificity in acupuncture and also addresses studies that do not support this concept. Further research is needed to elucidate the point-specific actions of acupuncture.

    ABSTRACT: Studies have revealed that apelin is a novel multifunctional peptide implicated both in blood pressure (BP) regulation and cardiac function control. Evidence shows that apelin and its receptor (APJ) in the rostral ventrolateral medulla (RVLM) may play an important role in central BP regulation; however, its role is controversial and very few reports have shown the relationship between acupuncture and apelin. Our study aims to both investigate the apelinergic system role in stress-induced hypertension (SIH) and determine whether acupuncture therapy effects on hypertension involve the apelinergic system in the RVLM. We established the stress-induced hypertensive rat (SIHR) model using electric foot-shock stressors with noise interventions. The expression of both apelin and the APJ receptor in the RVLM neurons was examined by immunohistochemical staining and Western blots. The results showed apelin expression increased remarkably in SIHR while APJ receptor expression showed no significant difference between control and SIHR groups. Microinjection of apelin-13 into the RVLM of control rats or SIHR produced pressor and tachycardic effects. Furthermore, effects induced by apelin-13 in SIHR were significantly greater than those of control rats. In addition, repetitive electroacupuncture (EA) stimulation at the Zusanli (ST-36) acupoint attenuated hypertension and apelin expression in the RVLM in SIHR; it also attenuated the pressor effect elicited by exogenous apelin-13 microinjection in SIHR. The results suggest that augmented apelin in the RVLM was part of the manifestations of SIH; the antihypertensive effects of EA might be associated with the attenuation of apelin expression and function in the RVLM, which might be a novel role for EA in SIH setting.

    ABSTRACT: Taking post-traumatic stress disorder (PTSD) as an example, we present a concept for transdisciplinary cooperation between life sciences and humanities. PTSD is defined as a long-term persisting anxiety disorder after severe psychological traumata. Initially recognized in war veterans, PTSD also appears in victims of crime and violence or survivors of natural catastrophes, e.g., earthquakes. We consider PTSD as a prototype topic to realize transdisciplinary projects, because this disease is multifacetted from different points of view. Based on physiological and molecular biological research to understand the causes of this disease, conventional academic medicine (to Western medicine) and pharmacology can offer a panel of drugs for treatment, albeit only with limited success. Hence, other treatment options are indispensable. Chinese medicine is frequently regarded as alternative to complement Western medicine. In fact, Chinese medicine offers a large array of both pharmacological and non-pharmacological treatments for PTSD patients. Narrative therapy represents a non-pharmacological approach combating PTSD both in Western medicine as well as in Chinese medicine to improve quality of life of affected patients. Narratives on traumatic experiences form a new genre of life writing in Asian American literature, whose excitement is considerably fueled by the tension between fictitious and very personal narratives taken from reality. Systematic academic reflections on narratives from PTSD patients in the field of Asian American studies may support the improvement of narrative therapy in medical practice. Chinese medicine has a strong philosophical background and may, therefore, serve as junction between life sciences with their strong rational and reductionistic way to generate new knowledge and more holistic approaches in traditional medicines and humanities. In this regard, Chinese medicine may represent a missing link between life science and life writing.

    ABSTRACT: The theory of acupoint specificity is the basis for elucidating the actions of acupoints as employed in clinical practice. Acupoint specificity has become a focus of attention in international research efforts by scholars in the areas of acupuncture and moxibustion. In 2006, the Chinese Ministry of Science approved and initiated the National Basic Research Program (973 Program), one area of which was entitled Basic Research on Acupoint Specificity Based on Clinical Efficacy. Using such approaches as data mining, evidence-based medicine, clinical epidemiology, neuroimaging, molecular biology, neurophysiology, and metabolomics, fruitful research has been conducted in the form of literature research, clinical assessments, and biological studies. Acupoint specificity has been proved to exist, and it features meridian-propagated, relative, persistent, and conditional effects. Preliminarily investigations have been made into the biological basis for acupoint specificity.
