OBJECTIVETo explore the rhythm regulatory mechanism of interleukin-6 (IL-6) in the process of moxibustion for rheumatoid arthritis (RA).
METHODSA total of 144 Sprague-Dawley (SD) rats were randomly divided into a blank group, a model group, a moxibustion group, a sham operation group, an operation group, an operation+moxibustion group, 24 rats in each one. Each group was divided into 4 time points (0:00 am, 6:00' am, 12:00 am, 6:00 pm), 6 rats in each time point. The Light-Dark 12 : 12 was given in all rats for light-dark cycle. Except the blank group, rats in the remaining groups were treated with intracutaneous injection of freund's complete adjuvant at right-side foot to establish the model of RA. After the model establishment, bilateral adrenal, glands were removed in the operation group and operation + moxibustion group, while those in the sham operation group were not removed with identical operation procedure. Rats in the moxibustion group and operation + moxibustion group were treated with grain-sized moxibustion from 7:00 am to 9:00 am at "Shenshu" (BL 23) and "Zusanli" (ST 36) once everyday, 6 times were taken as one session and 3 sessions were required tatclly, while rats in the remaining groups received identical fixation without moxibustion. The general health state and foot volume of rats were measured before model establishment, after establishment and after treatment. After treatment, rats were sacrificed at each time point to collect the blood sample and measure the content of IL-6 by using enzymne-immunoassay method.
RESULTSCompared with the blank group, the foot swelling in the model group was obviously increased (P<0. 05); the IL-6 maintained circadian rhythm (P<0. 05), but the peak phase had a backward trend, famplitude had an increased trend and the median was significantly lifted (P<0. 05). Compared with model group, !the foot swelling in the moxibustion group was obviously decreased (P<0. 05); the IL-6 maintained circadian. rhythm (P<0. 05), and the peak phase had a forward trend, amplitude had a decreased trend and the median was significantly reduced (P<0. 05). Compared with the moxibustion group, the foot swelling in the operation--moxibustion group was obviously increased (P < 0.05); the IL-6 maintained circadian rhythm (P < 0.5), but the peak phase moved forwrd, and the median was significantly elevated (P < 0.05).
CONCLUSIONThe IL-6 in plasma maintains significant pathological circadian rhythm in RA rats; with the complete hypothalamic-pituitary-adrenal axis, moxibustion is likely to regulate the circadian rhythm of IL-6 to play an important role of anti-inflammatory effect in RA rats.

Geographic tongue, also called benign migratory glossitis, is a common and superficial benign inflammatory disorder that affects the tongue epithelium. The majority of geographic tongue lesions typically manifest as irregular central erythematous patches. These lesions, which are caused by the loss of filiform papillae, are defined by an elevated whitish band-like border that can change location, size, and pattern over a period of time. Histological observations of the oral mucosa affected by geographic tongue revealed nonspecific inflammation. Some reports described cases of migratory stomatitis, wherein lesions simultaneously manifested on the extra lingual oral mucosa. This condition is also called ectopic geographic tongue, which is clinically and histologically similar to the type normally confined to the tongue. In most cases, patients are asymptomatic and do not require treatment. The condition may spontaneously exhibit periods of remission and exacerbation with good prognosis. The specific etiology of geographic tongue remains unknown. Geographic tongue is age-related and is prevalent among young individuals. Various etiological factors that have been suggested in literature include immunological factors, genetic factors, atopic or allergic tendency, emotional stress, tobacco consumption, hormonal disturbances, and zinc deficiency. Geographic tongue may coexist with other disorders, such as fissured tongue, psoriasis, diabetes mellitus, gastroin- testinal diseases, burning mouth syndrome, and Down syndrome. Experts currently disagree on whether geographic tongue is an oral manifestation of psoriasis. Moreover, some scholars suggest that geographic tongue is a prestage of fissured tongue. The objective of this review is to summarize current research on risk factors of geographic tongue.
