In traditional Chinese medicine, moxibustion is a local thermal therapy that is used for several conditions. Quantifying the effects of moxibustion therapy has been difficult because the treatment temperature depends on the physician's experience, and the temperature distribution in the target area is not uniform. This prospective observational study aims to quantify the effect of local thermal stimulation to the abdomen. We developed a heat transfer control device (HTCD) for local thermal stimulation. Twenty-four healthy subjects were enrolled and they underwent abdominal thermal stimulation to the para-umbilical region with the device for 20 min. Blood flow volume in the superior mesenteric artery (SMA) and brachial artery (BA), the heart rate and the blood pressure were measured at rest, 15 min after starting thermal stimulation and 10, 20, 30 and 40 min after completing thermal stimulation. Blood flow parameters were measured by high-resolution ultrasound. In the SMA, blood flow volume was significantly increased during thermal stimulation (), as well as at 10 min () and 20 min () after stimulation. In the BA, blood flow volume decreased at 40 min after stimulation (). In conclusion we could quantify the effect of local thermal stimulation with an HTCD and high-resolution ultrasound. Thermal stimulation of the para-umbilical region increased blood flow in the SMA 20 min after stimulation in healthy subjects.

Background The transposed basilic vein to brachial artery arteriovenous fistula (BBAVF) constitutes an alternative autogenous vascular access (VA) site for chronic hemodialysis (HD); however, the hemodynamic effects of this procedure have not been adequately studied. The purpose of this study is to evaluate the effects of BBAVF on systemic arterial pressure, cardiac function, and upper limb ischemia (ischemic steal syndrome) utilizing reproducible quantitative methods. Methods Ten consecutive patients (eight males; mean age: 65.10 ± 2.87 yrs) scheduled to undergo a brachial-basilic vein transposition were included, excluding patients with cardiac failure. Blood flow volume at the level of the AVF, systemic arterial pressure (SAP), cardiac output (CO) and digital brachial index (DBI) were measured intra-operatively, before and after the creation of the BBAVF, and post-operatively on the 30th post-operative day and on the 3rd post-operative month. Results SAP and DBI at 30 days and 3 months post-operatively were significantly lower compared to baseline. CO at 30 days and 3 months post-operatively was significantly higher compared to baseline; however, none of the patients developed cardiac failure. DBI remained ≥0.6 at 3 months, except in one case (0.59). Blood flow volume at the level of the AVF was positively correlated with CO levels on the 30th post-operative day. Mean clinical follow-up was 12 months (range: 4–15 months). In two cases (20%) the AVF was thrombosed (4th and 10th post-operative month). Conclusion This prospective quantitative study proves that the BBAVF does impact significantly upon SAP, CO, and DBI; however, it is safe in terms of high-output cardiac failure and ischemic steal syndrome.

The Mean

To investigate the role of chewing and taste in the meal-induced rapid increase in splanchnic blood flow, we compared the blood flow responses in the celiac artery (CA) and superior mesenteric artery (SMA) to chewing solid food with a chocolate taste (FOOD) and paraffin wax without taste (WAX). After 5 min of baseline measurement, 15 healthy subjects repeated chewing and expectorating the FOOD or WAX every 20 s for 4 min followed by 10 min of recovery measurement. We measured the mean blood velocity (MBV) in the CA and SMA. The baseline MBVs in the CA and SMA did not differ between the FOOD and WAX trials. The MBV in the CA was lower than baseline at the 1st min of chewing in both trials. It was higher than baseline at the 3rd min of FOOD chewing, whereas it did not increase during and after WAX chewing. The MBV in the CA was higher in the FOOD trial than in the WAX trial at the 3rd min of chewing and thereafter. In contrast, the MBV in the SMA did not change throughout the protocols. These results suggest that the taste of food plays a role in meal-induced hyperemia in the CA but not the SMA.
