Objective: To observe the clinical efficacy of acupuncture plus rehabilitation training in treating post-stroke deglutition disorders of qi-deficiency blood stasis pattern. Methods: Sixty-six patients with post-stroke deglutition disorders of qi-deficiency blood stasis patter were divided into an observation group and a rehabilitation group using the random number table method. The two groups both received conventional medications and supportive treatment for stroke. In addition, the observation group received acupuncture plus rehabilitation training while the rehabilitation group only received the same rehabilitation training. The interventions were conducted 3 times a week for a total of 4 weeks in both groups. They were evaluated using Kubota water swallowing test (KWST), Fujishima Ichiro food intake level scale (FILS) and symptoms score of traditional Chinese medicine (TCM) before and after treatment, and at the 1-month follow-up. The therapeutic efficacy was assessed at the 1-month follow-up. Results: The KWST grading and FILS result after treatment and at the follow-up were significantly different from those before treatment in both groups (all P<0.001); the results of these two items at the follow-up were not significantly different from those after treatment in the two groups (all P>0.05). There were significant differences in the KWST grading and FILS result between the two groups after treatment and at the follow-up (all P<0.05). The TCM symptoms score changed significantly after treatment and at the follow-up compared with that before treatment in both groups (all P<0.001). The TCM symptoms grading efficacy at the follow-up was significantly different from that after treatment in the observation group (P<0.05), while the difference was statistically insignificant in the rehabilitation group (P>0.05). The TCM symptoms grading efficacy in the observation group was significantly different from that in the rehabilitation group after treatment and at the follow-up (both P<0.05). Conclusion: Based on the conventional treatment for stroke, acupuncture plus rehabilitation training or use of rehabilitation training alone both can improve the clinical symptoms in post-stroke deglutition disorders of qi-deficiency blood stasis pattern, but acupuncture plus rehabilitation training can produce more significant efficacy and better long-term efficacy in improving TCM symptoms.

A new anastomat for digestive tract operations, based on the magnetic compressive technique and mechanical transmission mechanism, is composed of a removable head and a reusable body. The head includes two parts: the proximal end can be fixed to the body, and the distal end could be used for performing a purse string suture. The procedure of anastomosis is similar to that of the stapler, and the anastomoses is established using a pair of magnetic rings. The instrument makes magnamosis more simple and feasible, and it would facilitate the clinical application. The body of the anastomat is reusable and the head could be replaced according to the clinical scenarios, these could reduce the medical cost. The magnetic rings would be excreted with the feces, and there is no foreign body response at last.

This study was to build a canine portal hypertension model by intra-portal administration of high polymer material polyurethane and organic solvent tetrahydrofuran mixed solutions in order to evaluate the effectiveness of the model. Twelve local crossbreed dogs were selected randomly, with intra-portal administration of 8% (weight/volume) polyurethane- tetrahydrofuran solutions through an incision in the upper abdomen to build the portal hypertension model. We measured the portal vein pressure before modeling, during modeling, and four-, eight-, and twelve- weeks after modeling, respectively. Then we evaluated the effectiveness of the model comparing values of data with those data obtained before modeling started, which were regarded as the normal values. The results showed that the portal vein pressure rose by 2. 5 times after the solution administrated instantly as much as that before modeling, and maintained at 1. 5 times after 4 weeks. This method presents an easy operation, low animal mortality and reliable model of portal hypertension. Its less abdominal adhesions and its ability in keeping normal anatomic structure specially make it suit for surgical research of portal hypertension.
