The blood cells were labelled with sodium pertechnetate and fixed in 1 0%formalin; they were 22 × 15 μm in size and had a specific gravity close to that of dog red blood cells. These cells had no discernible effect on systemic hemodynamics after injection, did not agglutinate, were well mixed and evenly distributed throughout the body, and were completely extracted in one circulation through the mandible. The mandibular ramus was divided into six regions. and the blood flow rates in each were found to be similar to those reported in previous studies with radiolabelled carbonized, microspheres. Furthermore, the blood flow distribution pattern of the mandibular ramus determined in this study was identical to that of our previous study using the bone-seeking radionuclide method. We suggest that radiolabelled toad red blood cells are an ideal marker for measuring regional blood flow in the canine mandible.展开更多

Methods： Ninety-five elderly in-patients with low back pain caused by compression fractures were randomly divided into an observation group and an EA group according to the visit sequence. Both groups received the same basic treatment. In the EA group, 48 cases were treated with EA at Jiaji （EX-B 2） points plus the basic therapy; 47 cases in the observation group received the basic treatment plus EA and hydro-acupuncture with sinomenine hydrochloride at Jiaji （EX-B 2） points. The levels of osteoprotegerin （OPG） and interleukin-1β（IL-1β） in peripheral blood were measured by enzyme-linked immunosorbent assay （ELISA） before and at the 21st day of treatment in both groups. Oswestry disability index （ODI） and visual analog scale （VAS） scores were used to analyze the clinical efficacy. Results： After treatment, the OPG content in the observation group was higher with statistical significance compared with that before treatment in the observation group and after the treatment in the EA group, respectively （both P〈0.05）; the content of IL-1β, ODI and VAS scores were lower than those before treatment in the observation group and after treatment in the EA group with statistical significances （all P〈0.05）. Conclusion： The combination of EA and hydro-acupuncture with sinomenine hydrochloride at Jiaji （EX-B 2） points is effective for low back pain caused by compression fractures in the elderly, and is superior to EA at Jiaji （EX-B 2） points alone.展开更多
