Chronic pain is a significant public health problem that afflicts nearly 30% of the global population, but current pharmacotherapies are insufficient. Previous report indicated that N-demethylsinomenine, an active metabolite of sinomenine, is efficacious against postoperative pain. The present study investigated whether N-demethylsinomenine is effective for chronic painful conditions or whether repeated treatment alters its effect. Both chronic constriction injury (CCI) surgery and complete Freund's adjuvant (CFA) intraplantar injection induced significant and reliable mechanical allodynia at least for 7 days. Acute treatment with N-demethylsinomenine (10–40 mg/kg, i.p.) dose-dependently attenuated the mechanical allodynia both in CCI-induced neuropathic pain and CFA-induced inflammatory pain in mice. The potency of N-demethylsinomenine for reducing CFA-induced mechanical allodynia was slightly higher than sinomenine. During the period of repeated treatment, N-demethylsinomenine maintained its anti-allodynic effect against both neuropathic and inflammatory pain without producing carry-over effect. Pretreatment with bicuculline, a selective γ-aminobutyric acid type A (GABAA) receptor antagonist, almost completely blocked the anti-allodynia of N-demethylsinomenine (40 mg/kg) both in CCI and CFA-treated mice. Our findings indicated that N-demethylsinomenine exhibits GABAA receptor-mediated anti-allodynic effects in mouse models of neuropathic and inflammatory pain, suggesting it may be a useful novel pharmacotherapy for the control of chronic pain.

A Chinese medicine (CM) approach, designed based on the clinical experiences of the West Los Angeles Center for Traditional Chinese Medicine, is a practical path for assessing and treating breast cancer survivors. The approach consists of balancing the body with deciphering the cause of the patient's chief complaints by assessing and recognizing the six physiological dysfunctions that include gastrointestinal problems, sleeps problems, emotional imbalance, low body energy, menstrual change and pain. Multifaceted interventions are used for eliminating various CM pathologies based on identifying the basic CM patterns (syndromes) differentiation. Watching to assess the above two situations dynamically is used for outcome evaluation and predicting prognosis. Therefore this approach is called BMW. It can serve as a reference for CM clinical practice and integrative clinical care. It also can be used to simplify the clinical interpretation of CM and provide an easier way for CM doctors to communicate with Western medical doctors and patients. Additionally, it can be used as a guide for patients to assess their own symptoms for self-monitoring and self-care. [ABSTRACT FROM AUTHOR]

Erxian Tang (..., Exr) is a Chinese herbal formula developed for the treatment of menopausal syndrome in women, in the past 50 years, EXT has shown positive efficacy in the treatment of many chronic diseases in TCM, involving syndrome types of Shen (...) yin-yang deficiency, yin-deficiency caused yang-flourishing, and disharmony of Chong-Ren meridian. Experimental studies have revealed that EXT has multiple pharmacological actions on such multiple targets as hypothalamus-pituitary-target gland axis, immune function and free radical metabolism, etc. [ABSTRACT FROM AUTHOR]
