[Overview on the modern development of fire needling device: from tradition to innovation].

The appropriate needle device is crucial for obtaining the curative effect of fire needling therapy. The article introduces the material specification, clinical operation, indications, characteristics and advantages of the contemporary traditional fire needling devices (e.g. He's fire needle and Shi 's fire needle) and the contemporary new-type ones (e.g. fire needling with filiform needle and micro-needle); and determines the innovations of modern fire needling. It is anticipated that the needle specifications, production process and operation standard of fire needling devices should be further unified so as to provide the references for the selection of fire needling devices in treatment based on clinical syndrome differentiation and expand the clinical application of fire needling therapy.

[Innovation, development and application of contemporary fire needling].

Physicians in the past dynasties have improved the theory of fire needling from the aspects of fire needling instruments, clinical efficacy, application scope, operation, precautions, etc., which promoted the clinical application of fire needling. Modern fire needling breaks through the traditional clinical taboos such as heat syndrome, face, forbidden acupoints, and no needle retention. By using modern fire needling with various types, characteristics and functions, multiple needles and multiple methods are used to treat various diseases, which can further exert the therapeutic effect of fire needling and promote the popularization and application of fire needle therapy.

[Effect of fire-needle intervention on joint function, cartilage impairment and inflammatory response in knee osteoarthritis rats].

OBJECTIVE: To observe the effect of fire-needle stimulation of "Neixiyan"(EX-LE4) and "Dubi"(ST35) on changes of motor function, structure of cartilage degradation and inflammatory factors in knee osteoarthritis (KOA) rats, so as to explore its underlying mechanisms in improving KOA. METHODS: Thirty-nine male SD rats were randomly divided into normal, model and fire-needle groups (n＝13 in each group). The KOA model was established by injection of Monoiodoacetate (MIA, 1 mg) into the lumen of the right knee joint. On the 7th day after successful modeling, fire-needle was applied to EX-LE4 and ST35, twice a week for 3 weeks. The rats' behavioral reactions of gait (0 to 3 points) and claw pressure (0 to 3 points) were scored, and histopathological changes scored by assessing the impairment grade (0 to 6) and stage (0 to 4) of the articular cartilage after safranin O-fast green staining. The contents of serum Interleukin (IL)-1α， Tumor necrosis factor α(TNF-α), IL-10, IL-37 and transforming growth factor ß(TGF-ß) were assayed by ELISA, and ultrastructural changes were observed under transmission electron microscope(TEM). RESULTS: After modeling, the gait and claw-pressure scores were significantly increased in the model group in comparison with the normal group (P<0.05), and the OA score and contents of serum IL-1α and TNF-α were also appa-rently increased in the model group relevant to the normal group (P<0.05，P<0.01), while the levels of serum IL-10, IL-37 and TGF-ß remarkably decreased in the model group in contrast to the normal group (P<0.01). After the intervention, the increase of gait and claw-pressure and OA scores, as well as serum IL-1α and TNF-α contents, and the decrease of serum IL-10, IL-37 and TGF-ß levels were all reversed in the fire needle group (P<0.05, P<0.01). Outcomes of TEM showed more and larger lipid droplets, swollen mitochondria with some vacuoles, and expanded, broken or dissolved rough endoplasmic reticulum in the model group, which was milder in the fire-needle group. CONCLUSION: Fire-needle can improve motor function and relieve impairment of articular cartilage of KOA rats, which may be related to its effects in reducing inflammatory factors and in increasing anti-inflammatory factor levels.

Overview of current researches on Tibetan medicine "zuotai" / 中国中药杂志

"Zuotai" is one of the main raw material of many rare Tibetan medicine, and it plays a important role in the system of Tibetan medicine. There are some toxic heavy metals in "Zuotai", such as Hg, Au, Pb and so on. As a result, it's urgent to study the safety and effectiveness of "Zuotai" in depth. This paper will analyze and induce the resent progress of the study about "Zuotai". With constipation, "Zuotai" and "Zuotai" as key words, CNKI, CHINAINFO, CQVIP were retrieved, Springer were retrieved besides. Relevant 86 references were obtained. Twenty-two for reference were adopted through screening. The paper reviewed the resent progress of the study about "Zuotai" in chemical composition, pharmacodynamics and pharmacokinetics, toxicology and clinical application. This will establish the basis for further study.

[Summarization of professor He Pu-ren's channel syndrome differentiation for treatment of complicated and difficult diseases].

Channel syndrome differentiation is a more commonly-used syndrome differentiation method of Professor HE Pu-ren clinically, which includes the 3 aspects: differentiation of diseases and syndromes on the channel parts along the body surface; differentiation of diseases and syndromes of the internal organs connected with the channels; differentiation of qi and blood of the channels. According to results of the channel syndrome differentiation, with flexible application of the HE's Santong methods and selection of corresponding treatment program, many complicated and difficult diseases are cured.
