Objective To clarify the diagnostic value of oblique axial scan parallel to the course of the anterior talofibular ligament in magnetic resonance imaging of anterior talofibular ligament in patients with chronic ankle instability. Methods 96 patients with ankle injury who were admitted into our hospital form June 2010 to March 2015 were examed with oblique axial scan beside the routine axial magnetic res-onance imaging examination. The grade of the anterior talofibular ligament injury and confirmed full-length views of the anterior talofibular lig-ament were analyzed by two musculoskeletal radiologists ( with more than 5 years experience) , and associated lesions were also checked. Re-sults The full-length view of the anterior talofibular ligament was checked in 69 patients (71. 8%) through the routine axial view and it was checked in 93 patients (96. 9%) through the oblique axial scan view. Anterior talofibular ligament injury was checked in 71 patients through the oblique axial scan, which was 19 patients more than that through the routine axial. Conclusion An additional oblique axial scan is use-ful in evaluation of anterior talofiibular ligament in patients with ankle injury.

In order to observe the growth, expansion and differentiation of the cultured bone marrow stromal cells (BMSC), we isolated the BMSC from adult SD rats and cultivated them with LIF and bFGF. Then, we cultured and induced the stem cells by using retinoic acid and the culture medium confected in our lab by ourselves. We found that the BMSC could expand and generate clones when they were cultured in vitro. These cells subcultured grew rapidly and differentiated into neuron-like cells and astrocyte-like cells. The results showed that BMSC have the abilities to self renew and differentiate, thus demonstrating the culture method we used is suitable for the culture of BMSC in vitro. The bone marrow stromal cell is not difficult to obtain; it is capable of expanding and differentiating in culture. If the culture condition is appropriate, it can differentiate into neuron and astrocyte. So, it is a kind of perfect seed cells.

Objective:To evaluate the effect of transcutaneous electrical acupoint stimulation (TEAS) on inflammatory responses during intestinal mucosal barrier damage caused by gastrointestinal surgery in the rats.Methods:Forty-five healthy male Sprague-Dawley rats, aged 7-8 weeks, weighing 220-260 g, were divided into 3 groups ( n=15 each) by a random number table method: control group (C group), gastrointestinal surgery group (S group), and TEAS group (T group). Rats underwent pylorectomy and Roux-en-Y gastrojejunal anastomosis to establish gastrointestinal surgery models in S and T groups, while group C received no treatment.In group T, bilateral Zusanli and Hegu acupoints were stimulated with disperse-dense waves, current intensity 5 mA, frequency 2 Hz, from 30 min before surgery until the end of operation.Only electrode patches were applied, but no stimulation was applied in group S. Five rats were randomly selected from each group and sacrificed at 12, 24 and 48 h after surgery (T 1-3), and ileal tissues were taken after anesthesia.The pathological changes of ileal tissues were observed with a light microscope and scored according to Chiu.Enzyme-linked immunosorbent assay was used to determine contents of interleukin-6 (IL-6), tumor necrosis factor-alpha (TNF-α), diamine oxidase (DAO) and intestinal fatty acid-binding protein (I-FABP). Western blot was used to detect the expression of occludin, claudin-3 and ZO-1.The immunohistochemical method was used to determine the percentage of occludin, claudin and zonula occludens-1 (ZO-1) positive cells. Results:Compared with group C, Chiu′s scores and contents of ileal IL-6, TNF-α, DAO and I-FABP were significantly increased, the percentage of occludin, claudin-3 and ZO-1 protein positive cells was decreased, and the expression of occludin, claudin-3 and ZO-1 was down-regulated at T 1-3 in group S and group T ( P<0.05). Compared with group S, Chiu′s scores and contents of ileal IL-6, TNF-α, DAO and I-FABP were significantly decreased, the percentage of occludin, claudin-3 and ZO-1 protein positive cells was increased, and the expression of occludin, claudin-3 and ZO-1 was up-regulated at T 1-3 in group T ( P<0.05). Conclusion:TEAS can reduce the intestinal mucosal barrier damage caused by gastrointestinal surgery by inhibiting the inflammatory response in rats.
