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.

Objective To investigate the correlation between the baseline serum caveolin-1 (Cav-1) levels and the clinical outcome in patients with acute ischemic stroke at day 90 after onset. Methods Consecutive patients with acute ischemic stroke treated in hospital were enrolled. The Cav-1 levels were measured by the enzyme-linked immunosorbent assay. Functional outcomes were assessed at day 90 after onset using the modified Rankin Scale (mRS), and mRS 0-2 was defined as good outcome. The demographic and clinical characteristics of the good outcome group and the poor outcome group were compared. Multivariate logistic regression analysis was used to identify the correlation between the low serum Cav-1 levels and the poor outcome at day 90 after onset. Results A total of 169 patients with acute ischemic stroke were included in the analysis, including 116 males (68. 5% ). Their age ranged from 50 to 83 years (mean, 63. 4 ± 9. 1). The mean serum Cav-1 level was 5. 483 ± 2. 617 ng/ml. Eighty-three-patients (49. 1% ) were in the good outcome group and 86 (50. 9% ) were in the poor outcome group. Univariate analysis showed that the proportions of patients in subcortical infarct (60. 5% vs. 43. 4% ; χ2 = 4. 944, P = 0. 026) and diffusion-weighted imaging-Alberta Stroke Program Early CT Score, (DWI-ASPECT) ≤7 (58. 1% vs. 40. 9% ; χ2 = 4. 984, P = 0. 026), as well as age (65. 5 ± 8. 9 years vs. 61. 2 ± 10. 7 years; t = 2. 793, P =0. 006), baseline systolic blood pressure level (140. 6 ± 17. 2 mmHg vs. 134. 9 ± 13. 4 mmHg; t = 2. 368, P = 0. 019; 1 mmHg = 0. 133 kPa), and National Institutes of Health Stroke Scale (NIHSS) score (4. 8 ± 3. 4 vs. 3. 9 ± 2. 2; t = 2. 211, P = 0. 036) were significantly higher than those of the good outcome group, and the serum Cav-1 level was significantly lower than that of the good outcome group (4. 9 ± 2. 3 ng/ml vs. 6. 1 ± 2. 1 ng/ml; t = 2. 977, P = 0. 003). After adjusting for the related confounding factors, multivariate logistic regression analysis showed that the low Cav-1 level was an independent predictor of poor outcome at day 90 in patients with acute ischemic stroke (odd ratio, 1. 157, 95% confidence interval 1. 016-1. 319;P = 0. 028). Conclusion The low serum Cav-1 level is an independent predictor of poor outcome in patients with acute ischemic stroke.

Aim To research the synergistic effect of hyperlipoproteinemia and Aβ in the processing of Alzheimer′s disease.Methods Seventy SD rats were randomly divided into seven groups, and dealt with D-gal(hypodermic injection), hyperlipemia diet, microinjection into both side of CA1 section in hippocampus, independently.Morris water maze(MWM) test was used to evaluate the spatial memory impairments.Tau and tau(pThr181) pathology in the hippocampus were detected using Western blot and immunohistochemistry.Nissl′s staining was used to detect cell apoptosis.Results Aβ25-35-treated rats showed significant impairments of spatial memory in MWM test, especially in the group of D-gal+Aβ25-35+HLD(P<0.01).Furthermore, these rats treated with Aβ25-35, D-gal, and hyperlipemia diet, exhibited significantly increased phosphorylation of tau, particularly in the Thr181 site.Conclusion Hyperlipoproteinemia is the risk factor for older person, which could strengthen the toxic effect of Aβ, and promote phosphorylation of tau.

Objective To analyze the magnetic resonance imaging (MRI)and histologic features of the synchronous bilateral primary breast cancer (sBPBC).Methods MRI findings and pathologic types of sBPBC in 20 patients in our institute were reviewed retrospectively. The MRI features of sBPBC were compared with the pathologic types,respectively.Results 20 sBPBC patients with 41 lesions were found with the most common pathological type of invasive ductal carcinoma in 26 (26/41 ).Bilateral lesions had the same pathological types in 1 1 patients(1 1/20),and different types in 9(9/20).The MRI features of invasive breast cancer were more characteristic than that of early breast cancer.In 20 patients,the first and second primary breast cancers with similar MRI findings were found in 6(6/20).In 10 patients with sBPBC,the first cancer was advanced breast cancer,and the second was early or low grade breast cancer.Conclusion (1)The most common pathological type of sBPBC is invasive ductal carcinoma,and the pathological types of bilateral lesions are not similar. (2)The MRI features of the first and the second lesions in bilateral primary breast cancer showed lower similarity,and the bilateral lesions should be diagnosed independently.(3)In patients with sBPBC,some cancers are advanced breast cancers,and the second ones are early cancers,suggesting the lesion should be followed up if the contralateral one is diagnosed as breast cancer.
