In recent years research explored different acupuncture stimulation techniques but interest has focused primarily on somatic acupuncture and on a limited number of acupoints. As regards ear Acupuncture (EA) there is still some criticism about the clinical specificity of auricular points/areas representing organs or structures of the body. The aim of this study was to verify through (Functional magnetic resonance imaging) fMRI the hypothesis of EA point specificity using two auricular points having different topographical locations and clinical significance. Six healthy volunteers underwent two experimental fMRI sessions: the first was dedicated to the stimulation of Thumb Auricular Acupoint (TAA) and the second to the stimulation of Brain Stem Auricular Acupoint (BSAA). The stimulation of the needle placed in the TAA of the left ear produced an increase in activation bilaterally in the parietal operculum, region of the secondary somatosensory area SII. Stimulation of the needle placed in the BSAA of the left ear showed a pattern that largely overlapped regions belonging to the pain matrix, as shown to be involved in previous somatic acupuncture studies but with local differences in the left amygdala, anterior cingulate cortex, and cerebellum. The differences in activation patterns between TAA and BSAA stimulation support the specificity of the two acupoints. Moreover, the peculiarity of the regions involved in BSAA stimulation compared to those involved in the pain matrix, is in accordance with the therapeutic indications of this acupoint that include head pain, dizziness and vertigo. Our results provide preliminary evidence on the specificity of two auricular acupoints; further research is warranted by means of fMRI both in healthy volunteers and in patients carrying neurological/psychiatric syndromes.

3-Hydroxy-3-methylglutaryl coenzyme A (HMG-CoA) reductase inhibitors are established drugs for the treatment of hypercholesterolemia, but several studies have shown that benefits obtained with these drugs are not causally related only to regression of cholesterol lowering. Moreover, in experimental models of progressive renal disease, statins have reduced the extent of glomerulosclerosis. This study evaluated the antiproteinuric effect of a daily dose of 40 mg fluvastatin for 6 months in moderately proteinuric patients with immunoglobulin A nephropathy, stable renal function, and no indicators of poor long-term prognosis. The effects of therapy were evaluated on the basis of 24-hour proteinuria (total proteinuria and albuminuria), albuminemia, creatinine clearance, cholesterol, and triglyceride values. Renal function remained stable in all patients. A significant decrease in proteinuria was observed after 6 months of therapy and persisted for all the observations. An increase in serum albumin was observed after 6 months of therapy. This study suggests that there is an antiproteinuric effect of HMG-CoA reductase inhibitors in moderately proteinuric patients with immunoglobulin A nephropathy.
