Background
Hydroxychloroquine (HCQ) is a widely prescribed medication to patients with systemic lupus erythematosus (SLE), with potential anti-inflammatory effects. This study was performed to investigate the efficacy of HCQ therapy by serial assessment of disease activity and serum levels of proinflammatory cytokines in SLE patients.Methods
In this prospective cohort study, 41 newly diagnosed SLE patients receiving 400 mg HCQ per day were included. Patients requiring statins and immunosuppressive drugs except prednisolone at doses lower than 10 mg/day were excluded. Outcome measures were assessed before commencement of HCQ therapy (baseline visit) as well as in two follow-up visits (1 and 2 months after beginning the HCQ therapy). Serum samples of 41 age-matched healthy donors were used as controls.Results
Median levels of IL-1β (p?<?0.001), IL-6 (p?=?0.001), and TNF-α (p?<?0.001) were significantly higher, whereas, median CH50 level was significantly lower (p?<?0.001) in SLE patients compared with controls. Two-month treatment with HCQ resulted in significant decrease in SLEDAI-2K (p?<?0.001), anti-dsDNA (p?<?0.001), IL-1β (p?=?0.003), IL-6 (p?<?0.001) and TNF-α (p?<?0.001) and a significant increase in CH50 levels (p?=?0.012). The reductions in SLEDAI-2K and serum levels of IL-1β and TNF-α were significantly greater in the first month compared with the reductions in the second month.Conclusion
HCQ therapy is effective on clinical improvement of SLE patients through interfering with inflammatory signaling pathways, reducing anti-DNA autoantibodies and normalizing the complement activity.5.

Straub-tail behavior was induced by subcutaneous injection of different doses (10-60 mg/kg) of morphine to mice. The maximum response was obtained with 20-40 mg/kg of the drug. The response induced by morphine (40 mg/kg) was decreased by intraperitoneal administration of different doses of clonidine (0.05-0.1 mg/kg). Pretreatment of animals with yohimbine (1-4 mg/kg i.p.) reversed the inhibitory action of clonidine. Yohimbine did not elicit any response by itself. Administration of prazosin (0.25, 0.5, and 1 mg/kg) reduced the morphine response. The combination of prazosin with yohimbine (1 mg/kg), but not with clonidine (0.05 mg/kg), caused a potentiated inhibition of the morphine effect. Phenylephrine (2-6 mg/kg i.p.) did not elicit any effect by itself and also did not alter the response induced by morphine or morphine plus clonidine. Dobutamine (2.5-10 mg/kg i.p.), atenolol (2.5-10 mg/kg i.p.), salbutamol (2.5-10 mg/kg i.p.), and propranolol (2.5-10 mg/kg i.p.) did not alter morphine-induced Straub-tail behavior in mice. In conclusion, activation of alpha2-adrenergic pathways contributes to morphine-induced Straub tail, while alpha1- and beta2-adrenergic may not be involved in this phenomenon. 相似文献

ObjectivesCardiovascular disease may be linked to hearing loss through narrowing of the nutrient arteries of the cochlea, but large-scale population-based evidence for this association remains scarce. We investigated the association of carotid atherosclerosis as a marker of generalized cardiovascular disease with hearing loss in a population-based cohort.DesignCross-sectional.SettingA population-based cohort study.Participants3724 participants [mean age: 65.5 years, standard deviation (SD): 7.5, 55.4% female].MethodsUltrasound and pure-tone audiograms to assess carotid atherosclerosis and hearing loss.ResultsWe investigated associations of carotid plaque burden and carotid intima-media thickness (IMT) (overall and side-specific carotid atherosclerosis) with hearing loss (in the best hearing ear and side-specific hearing loss) using multivariable linear and ordinal regression models. We found that higher maximum IMT was related to poorer hearing in the best hearing ear [difference in decibel hearing level per 1-mm increase in IMT: 2.09 dB, 95% confidence interval (CI): 0.08, 4.10]. Additionally, third and fourth quartile plaque burden as compared to first quartile was related to poorer hearing in the best hearing ear (difference: 1.06 dB, 95% CI: 0.04, 2.08; and difference: 1.55 dB, 95% CI: 0.49, 2.60, respectively). Larger IMT (difference: 2.97 dB, 95% CI: 0.79, 5.14), third quartile plaque burden compared to first quartile (difference: 1.24 dB, 95% CI: 0.14, 2.35), and fourth plaque quartile compared to first quartile (difference: 2.12 dB, 95% CI: 0.98, 3.26) in the right carotid were associated with poorer hearing in the right ear.Conclusions and ImplicationsCarotid atherosclerosis is associated with poorer hearing in older adults, almost exclusively with poorer hearing in the right ear. Based on our results, it seems that current therapies for the prevention of cardiovascular disease may also prove beneficial for hearing loss in older adults by promoting and maintaining inner ear health. 相似文献
