To study the antiarrhythmic effect of the newly developed alpha/beta-blocker TJ0711, a variety of animal models of arrhythmia were induced by CaCl2, ouabain and ischemia/reperfusion. Glass microelectrode technique was used to observe action potentials of right ventricular papillary muscle of guinea pig. The onset time of arrhythmia induced by CaCl2 was significantly prolonged by TJ0711 at 0.75, 1.5 and 3 mg x kg(-1) doses. TJ0711 (1.5 and 3 mg x kg(-1)) can significantly shorten the ventricular tachycardia (VT) and ventricular fibrillation (VF) duration, the incidence of VF and mortality were significantly reduced. On ischemia-reperfusion-induced arrhythmic model, TJ0711 (0.25, 0.5, 1 and 2 mg x kg(-1)) can significantly reduce the ventricular premature contraction (PVC), VT, VF incidence, mortality, arrhythmia score with a dose-dependent manner. At the same time, rats serum lactate dehydrogenase (LDH) and creatine kinase (CK) activities decreased significantly by TJ0711 (1 and 2 mg x kg(-1)). Ouabain could cause arrhythmia in guinea pigs, when TJ0711 (0.375, 0.75, 1.5 and 3 mg x kg(-1)) was given, the doses of ouabain inducing a variety of arrhythmia PVC, VT, VF, cardiac arrest (CA) were significantly increased with a dose-dependent manner. In the TJ0711 0.1-30 micromol x L(-1) concentration range, guinea pig right ventricular papillary muscle action potential RP (rest potential), APA (action potential amplitude) and V(max) (maximum velocity of depolarization) were not significantly affected. APD20, APD50 and APD90 had a shortening trend but no statistical difference with the increase of TJ0711 concentration. TJ0711 has antiarrhythmic effect on the sympathetic nerve excitement and myocardial cell high calcium animal arrhythmia model. Myocardial action potential zero phase conduction velocity and resting membrane potential were not inhibited by TJ0711. APD20, APD50 and APD90 were shortened by TJ0711 at high concentration. Its antiarrhythmic action mechanism may be besides the action of blocking beta1 receptor, may also have a strong selective blocking action on alpha1 receptor and reducing intracellular calcium concentration.

Nimesulide is a new non-steroidal anti-inflammatory drug (NSAID). In this paper, its antiinflammatory, analgesic and antipyretic effects in mice rat or rabbit were evaluated. Nimesulide inhibited the ear oedema induced by croton oil in mice (ED50=49. 2 mg ? kg-1). It inhibitated rat hind paw oedema induced by carragreenin (ED50= 2.75 mg ? kg-1). Oral dose (0. 6 mg ? kg-1) showed sup-pressive effect on adjuvant arthritis in rat. Oraldose (100 mg ? kg-1) decreased writhing induced by acetic acid. Similar effect was observed in hot plate test on mice. Nimesulide (2 mg ? kg-1) decreased body tempreture elevated by injecting peptone in rabbit (P

Objective:To examinethe absolute numbers of cluster of differentiation (CD4) + T cell subsets in peripheral blood of patients with rheumatism and further to develop a new immunomodulatory therapies which aimed to restore their imbalanced CD4 + T lymphocyte subpopulation. Methods:A total of 6 395 rheumatic patients [4 430 females, 1 965 males, mean age (49±15) years] and 206 healthy controls (HCs) were enrolled in this retrospective cross-sectional study, which included rheumatoid arthritis (RA), systemic lupus erythematosus (SLE), ankylosing spondylitis (AS), Psoriatic arthritis (PsA), systemic sclerosis (SSc), primary Sj?gren′s syndrome (pSS), Be?het's disease (BD), dermatomyositis/polymyositis (DM/PM), gout and vasculitis. Some patients received treatment combined with immunoregulatory drugs (IMiDs) such as low-dose interleukin (IL)-2, rapamycin, metformin, retinoic acid and coenzyme Q10. The absolute numbers of T helper cell (Th)1, Th2, Th17 and regulatory T cell (Treg) in peripheral blood (PB) of these individuals were measured by Flow Cytometery (FCM). Independent sample t test and paired sample t test were used to compare the levels of CD4 + T cell subsets in PB of patients and HCs, before and after treatment respectively, and P<0.05 was considered statistically significant. Results:Compared with HCs, the mean absolute number of Treg was significantly decreased [(31±15) cell/μl vs (27±17) cell/μl, t=3.407, P<0.01] and the ratio of Th17/Treg was increased in all patients [(0.3±0.2) vs ( 0.4±0.7), t=-9.508, P<0.01]. There was a significant increase in the number of Th17 in patients with AS [(10±8) cell/μl, t=-5.403, P<0.01], PsA[ (11±11) cell/μl, t=-3.829, P<0.01], SSc [(7±6) cell/μl, t=3.114, P<0.01], BD [(11±9) cell/μl), t=-4.774, P<0.01] and gout [(11±9) cell/μl, t= -4.604, P<0.01) , and we observed lower level of Treg in patients with RA[(28±15) cell/μl, t=3.032, P<0.01], SLE [(21±21) cell/μl, t=6.836, P<0.01], AS [(28±15) cell/μl, t=2.216, P<0.05], SSc [(27±16) cell/μl, t=3.698, P<0.05], BD [(27±17) cell/μl, t=2.502, P<0.05], DM/PM [(27±22) cell/μl, t=2.974, P<0.01) and gout [(28±15) cell/μl, t=2.079, P<0.05). After IMiDs combination treatment, the levels of CD4 + T subsets were increased. Interestingly, the expansion of Treg was much more dramatical than those of other effector T cells, resulting in a decrease in ratios of Th17/Treg, especially in SLE [(0.6±1.0) vs (0.5±0.4), t=3.157 , P<0.01]. Conclusion:Impaired balance of pro- and anti-inflammatory immune cells, especially insufficiency of Treg, might be a cornerstone of the pathogenesis of rheumatism. The new immunomodulatory therapies could relatively specifically promote Treg proliferation and restored patients' autoimmune tolerance, which isexpected to provide a new strategy for the treatment of rheumatism.
