Intravenous injection of l-stepholildine (SPD) 2.5, 10 and 40 mg/kg decreased blood pressure(BP ) by 30, 40 and 55% respectively in anesthetized dogs. SPD also decreased BP in anesthetized rats (0.5mg/kg iv, by 29% and 2-50 mg/kg injected into duodenum, by 17-36%) and rabbits (2.5 mg/kg iv, by 24%). It could inhibit the pressor reflexes induced by occluding carotid, stimulating vagus Or sciatic nerve. Furthermore, SPD 2.5 mg/kg injected into fourth cerebroventricle of dog decreased BP by 20%, and in pithed rats SPD 10-40 mg/kg iv depreased BP by 7-40%. These results indicate that both central and peripheral mechanisms are involved in the hypotens-ive action of SPD and the peripheral seems to be more important. As showed in previous papers the effect of SPD on ?-adrenoceptors may be one of the chief mechanisms of the hypotensive action induced by SPD.

In this article we analyzed the current development of moxibustion treating rheumatoid arthritis from the usefulness, advancement, synergistic effect as well as the variance between different kind of moxibustion. We concluded that moxibustion was an effective intervention for treating RA, and the methods used in moxibustion were searched in clinic. But the clinical tralls has a long way to go, we should pay more attention to the critical issues while in the use of moxibustion.

BACKGROUND: Moxibustion can improve the symptoms of rheumatoid arthritis and reduce inflammation, but there are no uniform operation standards. The moxibustiondistance becomes one of factor influencing the therapeutic efficacy.OBJECTIVE: To compare the effects of different moxibustion distances on rheumatoid arthritis, and to explore the optimal distance.METHODS: The 8 of 40 male Sprague-Dawley rats were randomlyselected as controls. The other 32 were used to make animal modes of collagen type Ⅱ-induced ankle arthritis, and then given moxibustion at Shenshu (BL23) and Zusanli (ST36) at an interval of 1, 2 and 3 cm, respectively, once daily, 10 minutes at each point, 6 days per course for three courses, with a course interval of 1 day. Model rats with no treatment acted as model group.RESULTS AND CONCLUSION: Compared with the control group, the toe volume, arthritis index and serum levels ofinterleukin-1β and tumor necrosis factor-α except the body mass were significantly increased in the model group (P < 0.01).After moxibustion treatment, these indexes were significantly decreased in the three treatment groups (P < 0.01), especially in the 1 and 2 cm groups (P < 0.01). Narrowed articular cavity, intra-articular inflammation and pannus formation were observed in the model group, while only moderate inflammatorycell infiltration and few pannus formation were found in the 1,2, 3 cm groups. These results indicate that moxibustion improvesjoint functions and regulates immune reaction by downregulating the levels of interleukin-1β and tumor necrosisfactor-α, as well as reducing synovial hyperplasia. In addition,the optimal distance for moxibustion is 1 or 2 cm, which is amomentous proposition to improve therapeutic efficacy.

Objective To analyze the outcome and prognosis-related factors of MA (mitoxantrone+cytarabine) regimen for acute myeloid leukemia(AML). Methods 102 untreated AML patients were treated with MA. All patients were divided into two groups according to age, blood white cell count(WBC), FrenchAmerican-British (FAB) morphology, level of lactate dehydrogenase (LDH) and immunophynotype respectively.Analyze the prognosis-related factors. Results The complete remission (CR), partial remission (PR), nonresponse (NR) rate, and remission rate (CR+PR) of all the 102 cases were 63.73 % (65/102), 17.65 % (18/102), 18.62 % (419/102)and 81.38 % (83/102) respectively. The patients younger than 60 years old, WBC＜100×109/L, LDH≤600 U/L, FAB-M2 morphology group had higher CR and remission rate. The CR rate of patients with CD7 positive had statistical difference from that of patients with CD7 negative (P ＜0.05), but the remission rate not. However, the CR and remission rate of patients with CD19 positive had no statistical difference from that of patients with CD19 negative (P ＞0.05). Conclusion These results suggest that use of MA regimen was effective and safe for AML. Age, WBC, FAB morphology, level of LDH and CD7 expression are prognosis-related factors for clinical outcome.

Objective: To observe the effect of different moxibustion durations on rats with rheumatoid arthritis (RA) and to evaluate the relationship between moxibustion amount and moxibustion efficacy.Methods: Eight rats were randomly selected as a normal group from the 40 male Sprague-Dawley (SD) rats, and the other 32 rats were used to establish typeⅡ collagen-induced RA models. After successful modeling, the 32 rats were randomly divided into a model group, a moxibustion for 20 min group, a moxibustion for 40 min group and a moxibustion for 60 min group, with 8 rats in each group. Rats in the normal group did not receive modeling and moxibustion intervention; rats in the model group did not receive moxibustion after modeling; rats in the moxibustion for 20 min group, the moxibustion for 40 min group and the moxibustion for 60 min group were treated with moxibustion at Shenshu (BL 23) and Zusanli (ST 36) for 20 min, 40 min and 60 min, respectively. Six days were a course of treatment, with a total of 3-course treatments and a 1-day rest between the courses of treatment. After treatment, the serum levels of interleukin (IL)-1β and tumor necrosis factor (TNF)-α, arthritis index (AI) scores, toe volumes and pathological score of synovitis were evaluated in the rats.Results: Compared with the normal group, the serum IL-1β and TNF-α levels, and the toe volumes in the model group were increased, and the differences were statistically significant (P<0.01), before the treatment. Compared with the model group, the serum IL-1β and TNF-α levels, toe volumes and arthritis index (AI) scores were significantly decreased in the moxibustion for 20 min group, the moxibustion for 40 min group and the moxibustion for 60 min group (P<0.05 orP<0.01 ). Compared with the moxibustion for 20 min group and the moxibustion for 60 min group, serum IL-1β and TNF-α levels, toe volumes and AI scores were decreased more significantly in moxibustion for 40 min group, and the differences were statistically significant (P<0.05 orP<0.01). There were no significant differences in serum IL-1β and TNF-α levels, AI scores and toe volumes between the moxibustion for 20 min group and the moxibustion for 60 min group (allP>0.05). The synovial histopathological improvement was the most obvious in the moxibustion for 40 min group, when the synovial histopathological changes were compared among the moxibustion for 20 min group, moxibustion for 40 min group and moxibustion for 60 min group.Conclusion: The therapeutic efficacy of moxibustion for 40 min in RA rats was more significant than that of moxibustion for 20 min and moxibustion for 60 min, indicating that the duration of moxibustion is the main factor affecting its therapeutic efficacy.

Objective: To explore the mechanism of moxibustion for rheumatoid arthritis (RA) by observing the metabolite changes in urine using liquid chromatography-mass spectrometry (LC-MS)-based metabolomic analysis. Methods: Twenty-four rats were randomly divided into a control group, a model group, and a moxibustion group. Rats in the model and moxibustion groups were established as collagen-induced arthritis (CIA) models. The control and model groups did not receive any intervention; rats in the moxibustion group received moxibustion at Shenshu (BL23) and Zusanli (ST36). After three weeks of intervention, ankle joint, serum, and urine samples were collected for pathological examinations and metabolomic tests. Results: After moxibustion treatment, the CIA rats showed increased body mass, reduced swelling of the hind paws and arthritis score, decreased serum cytokine levels, and improved histopathological evaluation of the ankle joint. Twenty-four significantly altered metabolites were found, mainly involved in alanine metabolism, taurine and hypotaurine metabolism, tricarboxylic acid cycle, phenylalanine metabolism, tyrosine metabolism, and primary bile acid biosynthesis. These metabolites may serve as potential biomarkers for RA. Conclusion: Moxibustion can effectively resist inflammation in CIA rats. The potential biomarkers and the abnormal metabolic pathways of RA can be identified by LC-MS-based metabolomics. Metabolomics may be an effective way to explain the mechanism of moxibustion in treating RA.
