Visfatin was recently reported as an adipokine and was found to exert insulin-mimicking effects.The results showed that the expression of visfatin parallelled with obesity and insulin resistance in long term high fat chow-fed rats.The expression of visfatin mRNA was decreased and the insulin resistance improved after rennin-angiotensin system was blocked.Visfatin may play an important role in the pathogenesis of insulin resistance.

OBJECTIVE: To compare inhibition effects of arsenacetylic acid(ASAC) on experimental H22 hepatoma-bearing mice in different forms of administration. METHODS: The mice were divided into 5 groups at random after inoculated with H22 hepatoma into their right axillas hypodermic by intraperitoneal injection(ip) and intravenous injection(iv), and then injected with normal saline,cyclophosphamide and different dosage of ASAC, observe the rate of tumor strain becoming tumor, the inhibition effects of the subjects and the effects of the subjects on mice's viscera. RESULTS: Compared with ip,either high, moderate or low dosage of ASAC by iv did have an obvious inhibitory effect on tumor and the tumor inhibition rates were 46.59%, 46.31% and 32.48% respectively; however, the spleen index in groups that of lower dosage of ASAC by two forms of drug administration were increased; there were death by poisoning in the group that iv with high dosage of ASAC.CONCLUSION: Compared with ip, the administration of ASAC by iv has a better effect on tumor.

Objective To explore the possible mechanisms of Arsenic Trioxide in treating rheumatoid arthritis(RA)by observing the changes of HE staining and NF-KB expression as well as the apoptosis of syn- oviocytes in adjuvant-induced arthritis rats.Methods After the animal model was set up on Wistar rats sue- cessfully,they were randomly divided into AA model group and arsenic trioxide treatment group.The treat- ment group were injected with 4 mg'kg~(-1)9?d~(-1)arsenic trioxid fluid for 7 days.All of the rats were killed 3 days after the complete of injections.The joint specimens were exposed,fixed,decalcified,wrapped and cut into slices.All slices were examined by HE stain and immunohistological evaluation.Results HE staining showed that when compared with the normal control group,the layers of synoviocytes of the AA group were increased to 6-8,and the arrangement of synoviocytes was disordered and heavy inflammatory cell infiltration were found in the AA group.In the arsenic trioxide treatment group,the layers of synoviocytes increased to 3～4,and medi- um amount of inflammatory cell infiltration were found.The intensity of synovial NF-kB(p65)positive stain in AA model group was significantly higher than that in the normal control group.The synovial expression and ac- tivation of NF-kB in the treatment group were decreased markedly,and did not return to normal level.The average gray scale calculation showed that there were significant differences between the three groups(P

Objective To assess the long efficacy and safety of Lamotrigine(LTG) monotherapy and add-on therapy different types of epileptic seizures in children.Methods According to the classification of the 1981 and 1989 International Union of Antiepileptic for epileptic seizure,a total of 124 cases with epilepsy were included in the study and divided into non-refractory group with 93 cases and refractory group with 31 cases.LTG treatment only or add-on were used.Original drug dosage was not changed and LTG was added slowly and carefully untill the terrible side effect appeared.The average monthly seizure frequency with baseline in the last 3 months was compared and the side effect was observed.Results Total efficiency was 72.6%,control rate was 51.6%.Total efficiency and control rate of the non-refractory group was 81.0% and 61.3%,which was significantly higher than those of refractory group(48.4%,22.6%).Total efficiency and control rate of the combination group with LTG and valproate sodium(VPA) was 78.4% and 54.5%,which was significantly higher than those of the group of LTG only(61.0%,44.0%).Clinical results was different significantly between the course of the observation period within and over 5 years(P

OBJECTIVETo investigate the effects and the related mechanisms of Jiajian Yunujian (JJYNJ) granules, which were made from traditional Chinese medicinal prescription, on hyperthyroidism graves.

METHODExcept that in the normal group, all mice were injected 350 mcirog x kg x d(-1) L-Thyroxin sodium to establish the hyperthyroidism graves model. The model mice were divided randomly into model control group, 3 different groups of JJYNJ granules at oral dosage of 2.17, 4.33, 8.66 g x kg(-1), every day and thiamazole group at oral dosage of 10 mg x kg(-1) every day, respectively. The body weight, heart/body weight index, heart rate (HR), spontaneous activity and oxygen consumption of all the mice were measured. The serum T3, T4 levels were evaluated with the method of RIA. Meanwhile, the effect of JJYNJ granules and thiamazole on iodine uptake by thyroid was determined by radio-assay.

RESULTJJYNJ granules could improve the symptoms caused by thyroxin, increase body weight (P < 0.05), reduce heart/body weight index, spontaneous activity and oxygen consumption (P < 0.05). The HR of model group was (794.5 +/- 47.8) beats x min(-1), significantly faster than that of normal group (682.5 +/- 116.4) beats x min(-1). Those of low, middle and high JJYNJ granule group were (736.9 +/- 66.6), (742.1 +/- 62.3), (715.8 +/- 102.8) beats x min(-1) respectively, obviously slower than that of model group (P < 0.05). The serum T3, T4 levels of model group were (3.85 +/- 0.960), (234.46 +/- 58.11) microg x L(-1), significantly higher than those of normal group (0.99 +/- 0.30), (65.94 +/- 13.94) microg x L(-1), P < 0.01). Those of middle, high of JJYNJ granule group were (2.57 +/- 0.81), (164.27 +/- 72.63) microg x L(-1) and (2.70 +/- 0.55), (157.26 +/- 35.03) microg x L(-1). Those of thiamazole group were (2.88 +/- 0.59), (172.65 +/- 39.73) miicrog x L(-1). These values were significantly lower than those of model group. Thiamazole could significantly inhibit the iodine uptake in thyroid (P < 0.01), but JJYNJ granules did not block that obviously.

CONCLUSIONJJYNJ granules could significantly improve the symptoms of experimental hyperthyroidism graves. Its mechanisms may be different from that of thiamazole, which is related to inhibiting the synthesis of thyroxin in thyroid.

Aim To study the mechanism of DXM and NAC inhibiting the expression of IL-8 and ICAM-1 in A549 cells. Methods The expression of IL-8 and ICAM-1 was detected by ELISA and flow cytometry re-spectively; the expression of GR,HDAC,AP-1,NF-κB was detected by Western blot, while the activity of HDAC was detected by spectrophotometry. ResultsThe increasing expression of IL-8 and ICAM-1 induced by TNF-α could be inhibited by DXM and NAC in A549 cells. DXM could inhibit the transcribed activa-tion of AP-1,NF-κB, and the expression of HDAC and its activity induced by TNF-α and LPS; NAC only in-hibited the transcribed activation of NF-κB, while it had no affection on the transcribed activation of AP-1 and the expression of HDAC and its activity. Conclu-sions DXM and NAC both have the anti-inflammatory effect. DXM plays the role of anti-inflammation through increasing the expression and activation of HDAC, in-hibiting the transcribed activation of AP-1 and NF-κB, while NAC has no effect on the expression and activa-tion of HDAC, which shows that NAC does not exert anti-inflammatory effect through acetylation signal.

Objective: To observe the clinical efficacy of heat-sensitive moxibustion plus Western medicine in treating patients with diabetic peripheral neuropathy (DPN). Methods: A total of 70 patients with DPN were divided into an observation group and a control group by sealed envelope method combined with the random number table method, with 35 cases in each group. The control group was treated with routine medicine, and the observation group was treated with heat-sensitive moxibustion on the basis of the treatment in the control group. After 2 courses of treatment, the scores of Toronto clinical scoring system (TCSS) and vibration perception threshold (VPT) in both groups were observed, and the clinical efficacy was compared. Results: During treatment, 3 cases dropped out in the control group and 4 cases in the observation group. After treatment, the total effective rate in the observation group was higher than that in the control group (P<0.05). The scores of TCSS and VPT in both groups decreased after treatment, and the intra-group comparison showed statistical significance (both P<0.05). The scores of TCSS and VPT in the observation group were lower than those in the control group, and the differences were statistically significant (both P<0.05). Conclusion: Heat-sensitive moxibustion plus Western medicine can improve the symptoms in patients with DPN, and has a better curative effect than the Western medicine alone.

Objective: To analyze associations of MRI-lesions and clinical features with disability in patients with multiple sclerosis (MS) in Shanghai, China. Methods: We studied patients with MS, identified from a survey in Shanghai, whose sites of lesions in the CNS was based on the MRI examinations. Associations between MRI-lesions, various clinical variables and the severity of disability were analyzed with univariate and multivariate logistic regression analysis. Results: There were 210 patients in this study. The disability of the patients with lesions confined to the spinal cord was significantly more severe than those with lesions in the brain (p < 0.008). Current age (OR: 1.041, 95% CI: 1.007~1.077), MS duration (OR: 1.082, 95% CI: 1.011~1.159) and MRI-lesions in the spinal cord (OR: 2.441, 95% CI: 1.039~5.737) were significantly associated with severity of disability on multivariate logistic regression analysis. Conclusion: MRI-lesions in the spinal cord, older age, a longer MS duration were significantly associated with a more severe disability in this MS study in Shanghai China.
