[Preliminarily analysis on traditional Chinese medicine advices in Treatise on Febrile Diseases].

To make a systematic analysis on literatures concerning traditional Chinese medicine (TCM) advices in Treatise on Febrile Diseases, and summarize the main connotations of traditional Chinese medicine advices, relevant TCM advices in Treatise on Febrile Diseases were collected, screened, compared, summarized and analyzed according to TCM dosage form preparation methods, TCM administration methods, medication contraindications and nursing after TCM administration. The literatures concerning medications in Treatise on Febrile Diseases were consulted, summarized and compared to standardize medicine advices and facilitate rational clinical application of TCMs. The standard medicine advices were as follows. The boiling water for TCMs shall be tap water and well water. The decoctions that have effects in promoting blood and meridians can be boiled with wine. The decoctions containing toxic components can be boiled with honey. Some TCMs shall be boiled with special methods, e. g. Herba Ephedra that could be boiled before other medicine and skimmed. Japonica rice could be added in decoctions to measure the duration of decoctions. Different dosages were required for different forms (litre, pill, medicine spoon). Administration times, temperature and frequency shall be adjusted according to target positions, functions and stage of illness. As for dietary contraindications during medication, thick porridges are recommended, where foods impacting medicine efficacy are prohibited. Regarding nursing after medication is important to recover physical functions, particularly warm porridges can go with diaphoretic recipes, while thick porridges can go with purgative recipes. And drug efficacies shall be defined by observing urine and excrements, and blood form. In conclusion, Treatise on Febrile Diseases is the first book that discusses TCM advices and records them in details. In this study, new standard medicine advices were proposed to provide important basis for improving clinical advices of TCMs and supports for developing the TCM dispensing technology.

[The protective mechanism study of fengshiqing recipe against bone destruction in CIA rats].

OBJECTIVE: To explore the protective mechanism of Fengshiqing Recipe (FR) against bone destruction in collagen-induced arthritis (CIA) rats. METHODS: Rats were divided into four groups in the experiment,i.e., the blank control group, the model group, the MTX group (MTX, 1 mg/1 000 g), and the FR group (24 g crude FR/kg). The CIA model was prepared except the blank control group. Medication was started in the MTX group and the FR group from the 14th day after modeling to the 56th day. The toe volume was measured on every Tuesday and Friday. Expression levels of serum IL-17, RANKL, MIP-1alpha were detected after 3-and 6-week intervention. The bone scintigraphy with nuclide (SPECT), bone mineral density (BMD), and the pathological section were observed to assess the intervention of drugs of heat clearing blood activating actions in the bone destruction of CIA rats. RESULTS: From the 10th day of modeling, the volume of both toes started to swell and reached the peak at about 21 days. It was obviously shrunk at about 30 days. Of them, the swelling degree was milder in the MTX group and the FR group than in the model group. Compared with the model group at the same phase, the levels of IL-17 and RANKL decreased in the MTX group after 3 weeks of intervention (P < 0.01, P < 0.05). The IL-17 level decreased in the FR group after three weeks of intervention (P < 0.05). The RANKL level decreased in the MTX group and the FR group after 6 weeks of intervention (P < 0.01, P < 0.05). Compared with the model group and the MTX group, the overall BMD and ankle BMD increased in the FR group after 6 weeks of intervention (P < 0.01, P < 0.05). The ankle ROI/mandible and the toe ROI/mandible were elevated in the FR group after 3 weeks of intervention (P < 0.05). Pathological results suggested that the joint lacunae was significantly widened, the hyperplasia of the synovial tissue was so severe, and the bone tissue was destroyed in the model group. Compared with the model group, the aforesaid conditions were significantly improved in the MTX group and the FR group. The cartilage structure was complete. CONCLUSION: QR could inhibit decreased BMD, prevent bone destruction, which might be achieved by down-regulating expression levels of IL-17, RANKL, and MIP-1alpha through the osteo immunological Th/RANKL system,inhibiting maturation and differentiation of osteoclasts, thereby, inhibiting bone destruction.
