Objective To observe the clinical efficacy of Runchang Xuanfei Shugan Formula in the treatment of slow transit constipation. Methods Totally 94 patients were randomly divided into treatment group and control group, with 47 patients in each group. Treatment group was given Runchang Xuanfei Shugan Formula, one dose per day, half a dose for morning and half a dose for evening, and the control group was given lactulose oral liquid, 15 mL each time, for morning and evening, and citrate moser Billy 5 mg, three times a day orally taken before meals. The treatment course for the two groups were 4 weeks, with three-month follow-up. The defecation symptom score, anxiety and depression score were observed, the colonic transit test meter was performed, and the side effects were recorded. Results The degree of defecation difficulty, defecation frequency, defecation time, abdominal distension and stool quality score of the two groups significantly decreased after treatment (P<0.05), and the treatment group was much lower than the control group after treatment and three months after treatment (P<0.05). The score of anxiety and depression (SAS, SDS) of the treatment group decreased significantly after treatment and three months after treatment (P<0.05), and had significant differences with the control group (P<0.05). The colon function was significantly improved after treatment in both groups (P<0.05), without statistical significance (P>0.05). Conclusion Runchang Xuanfei Shugan Formula can improve clinical symptoms of slow transit constipation, ease anxiety and depression of patients, and promote colon transmission function.

Objective: We investigated experimentally the changes of intestinal immunity following shock and resuscitation after trauma. Method:The experimental model was made in rats, which underwent laparotomy, then bleeding and reinfusing through the right fetmoral artery. Result: The concentration of IgA following shock and resuscitation were significantly higher than that before shock.. The concentration of IgA 24 h following resuscitation was the lowest, and was significantly lower than that at the end of shock.. The endotoxin in portal vein following shock and resuscitation were higher than that before shock.. The endotoxin level 24 h following resuscitation was the highest, and markedly higher than that at the end of shock. Conclusion: The traumatic shock and resuscitation are capable of causing intestinal immunosuppression and endotoxemia.

Objective To observe the clinical efficacy of scalp plus body acupuncture in treating urticaria.Method Eighty urticaria patients were randomized into a treatment group of 42 cases and a control group of 38 cases. The treatment group was intervened by scalp plus body acupuncture, while the control group was treated with conventional body acupuncture. The two groups were treated once every other day, 10 sessions as a treatment course. The symptoms and signs scores and serum immunoglobulin E (IgE) level were observed before the treatment and after 2 treatment courses, and the clinical efficacies were also compared between the two groups.Result The total effective rate and recovery rate were respectively 92.9% and 61.9% in the treatment group, versus 76.3% and 36.8% in the control group, and the between-group differences were statistically significant (P<0.05). After the treatment, the symptoms and signs scores significantly declined in both groups (P<0.05), and the symptoms and signs scores in the treatment group were markedly different from those in the control group (P<0.05). The serum IgE level in the treatment group after the intervention was significantly lower than that before the intervention (P<0.05). After the treatment, the serum IgE level in the treatment group was significantly different from that in the control group (P<0.05).Conclusion Scalp plus body acupuncture is an effective method in treating urticaria.

Objective To determine the three dimensional motion data of each segment of cervical vertebrae and analyze the characteristics of the intervertebral coupled motion during cervical axial rotation under physiological weight bearing. Methods A total of 16 healthy volunteers (ranging from 22 to 29, median age, 23 years) were recruited to our study. Any cervical spine disorder history, pain or other discomfort and malformations were excluded so as to avoid abnormal neck motion. These subjects underwent CT scans of their cervical segments in a supine position, and 3D models of C1-C7 were constructed. Next, each subject was asked to sit up straight and was positioned in the following sequence:maximal left and right twisting, while double oblique images by DFIS were taken simultaneously at each of the positions. Then, the CT models were matched to the osseous outlines of the images from the two oblique views to quantify the position of cervical vertebraes in 3D at each position. Through local coordinate systems at the center of vertebral bodies, changes of position and angle of each cephalad vertebrae relative to the cauddal one were calculated before and after the axial rotation. Results (1) In the axial rotation of the cervical spine, the contribution of C1/2 accounted for the most of the total cervical rotation range. For the lower levels, axial rotation was found to be maximal at C3/4 and C5/6, minimal at C2/3. (2) In cervical axial motion, C1/2 demonstrated a coupled lateral bending opposite to the axial rotation direction, while each segment of C2-7 demonstrated coupled lateral bending towards the same side of the axial rotation. Among these segments the lateral bending angle of C2/3 was smaller than angles of C3/4, C4/5 and C5/6. Conclusion This study investigated the cervical coupling behavior using the noninvasive 2D-3D matching technique and obtained the motion data at each cervical spinal segment. These findings will help to improve the understanding on physiological cervical spine movement and potential biomechanical mechanism and treatment of cervical spondylosis. Also our data may provide useful reference for the prosthesis design.
