Beat-to-beat cardiovascular variability analysis provides important information on the circulatory regulatory activities. Changes in the arterial pulse transmission or the opening condition of arteriolar openings might change the fluctuation pattern of the MBF supply, and thus change the complexity property therein. We performed complexity analysis of beat-to-beat laser Doppler (LDF) signals to study the microcirculatory-blood-flow (MBF) response at the needled site (Hegu acupoint) following acupuncture stimulation (AS). LDF signals were measured in male healthy volunteers (n=29). Each experiment involved recording a 20-minute baseline-data sequence and two sets of effects data recorded 0-20 and 50-70 minutes after stopping AS. Approximate-entropy (ApEn) analysis, which quantifies the unpredictability of fluctuations in a time series, was performed on each 20-minute beat-to-beat LDF data sequence. The present findings indicate that AS can not only improve the local blood supply but may also increase ApEn values and decrease MBF variability parameters. This was the first attempt to apply complexity analysis to LDF signals in order to elucidate microcirculatory responses following AS. The observed results are probably attributable to the contradictory effects on the MBF supply induced by AS, which might interfere with the microcirculatory regulatory activities so as to increase the complexity of LDF signals. The present findings could help to identify the mechanism underlying the effects of AS, might aid the development of an index for monitoring the induced microcirculatory regulatory responses, and thus provide an evidence-based connection between AS and modern physiology.

Nanomedicines are sub-micrometer-sized carrier materials designed to improve the biodistribution of i.v. administered (chemo-) therapeutic agents. In recent years, ever more efforts in the nanomedicine field have employed optical imaging (OI) techniques to monitor biodistribution and target site accumulation. Thus far, however, the longitudinal assessment of nanomedicine biodistribution using OI has been impossible, due to limited light penetration (in the case of 2D fluorescence reflectance imaging; FRI) and to the inability to accurately allocate fluorescent signals to nonsuperficial organs (in the case of 3D fluorescence molecular tomography; FMT). Using a combination of high-resolution microcomputed tomography (μCT) and FMT, we have here set out to establish a hybrid imaging protocol for noninvasively visualizing and quantifying the accumulation of near-infrared fluorophore-labeled nanomedicines in tissues other than superficial tumors. To this end, HPMA-based polymeric drug carriers were labeled with Dy750, their biodistribution and tumor accumulation were analyzed using FMT, and the resulting data sets were fused with anatomical μCT data sets in which several different physiologically relevant organs were presegmented. The robustness of 3D organ segmentation was validated, and the results obtained using 3D CT-FMT were compared to those obtained upon standard 3D FMT and 2D FRI. Our findings convincingly demonstrate that combining anatomical μCT with molecular FMT facilitates the noninvasive assessment of nanomedicine biodistribution.
