Objective To evaluate the effectiveness of Typodont-based table clinic competition (TCC) on undergraduate orthodontic education. Methods Students who have finished basic orthodon-tic courses made diagnosis,treatment strategy and performed orthodontic treatment for malocclusion cases on Typodonts. A self-design questionnaire was employed to investigate their perception to this pedagogy. Results The majority of participants(82.2%-92.9%) highly evaluated Typodont-based TCC. Conclu-sions Typodont-based TCC course is conducive to arousing students' study internets and to promoting association between theory and practice.

Objective To evaluate a combination therapy for huge tumors in the buttocks.Methods A total of 11 patients from our hospital were collected,among them 5 cases were of hemangioma,4 cases of neurofibroma,2 cases of soft tissue sarcoma.Before definite surgical resection all cases received tumor embolization with silk thread and gelatin-sponge article using Seldinger's technic.Subsequently,all patients underwent a successful tumor resection. Results Superselective embolization for all the cases'feeding arteries resulted in recession of the tumors and relatively well-demarcated margins,and all the lumps became softer.and the local pain was alleviated.Surgical resection could be radical with avoidance of fatal intraoperative hemorrhage.The 5 cases of hemangioma had a average operative bleeding of 450 ml,4 cases of neurofibroma had 420 ml,2 cases of soft tissue sarcoma had 150 ml.No patients needed intraoperative and postoperative blood transfusion.The operation time was about 2-3 hours,the normal tissues were preserved and the contour and function of the diseased limbs were very good.One case had a delayed incision healing,and the others had a healing by the first intention.There was no recurrence and other complications (like deep venous thrombosis)during a follow-up period of 4-8 months. Conclusions Surgical resection combined with interventional embolism for the treatment of huge tumors in the buttocks can reduce the risk of bleeding effectively during operation.It can improve the success rate of operation leading to satisfactory results.

Objective: To observe the clinical efficacy and eligibility of thumb-tack needle therapy based on meridian differentiation in treating cervical radiculopathy. Methods: A total of 70 patients with cervical radiculopathy were randomized into an observation group and a control group, with 35 cases in each group. Patients in the control group received thumb-tack needle based on conventional point selection, while those in the observation group received thumb-tack needle according to meridian differentiation. The visual analog scale (VAS) and clinical symptom scores in the two groups were compared before and after treatment, and the clinical efficacy of the two treatments was observed. Results: After treatment, the VAS score in both groups dropped significantly (both P<0.01), and the VAS score in the observation group was lower than that in the control group (P<0.01). The clinical symptoms score in both groups dropped significantly (all P<0.01), and the clinical symptoms score in the observation group was lower than that in the control group (P<0.01). The total effective rate in the observation group was higher than that in the control group (P<0.05). Conclusion: Thumb-tack needle therapy based on meridian differentiation can reduce pain score, improve clinical symptoms in patients with cervical radiculopathy, and produce more significant efficacy compared with conventional thumb-tack needle therapy.

A commonly used Chinese crude drug Allii Macrostemonis Bulbus has been shown to possess good anticancer activities and related properties such as antioxidation, nitrite scavenging, nitrosamine synthesis blocking and immune enhancement, and has been widely used as an effective auxiliary drug in the treatment of some malignant tumors. This paper systematically reviews the advances in the study of anticancer-related activities of Allii Macrostemonis Bulbus's various components such as raw juice, extracts, saponins, volatile oil, polysaccharides, nitrogen compounds, etc.

Objective To measure Ihe effect on rats spinal neuron flow according nerve roots repair time.Methods We adopted the experimental rats on the root avulsion and extravertebral foramen nerve root divison of C_(5～7).We divided them into four groupsin each which there were 16 ratsaccording the type of nerves root injury and repair timeGroup AC:the avulsed roots were reimplanted into the spinal cord and the transeeted roots were sutured to the proximal stump immediately.Group B,Dthe avulsed roots and the transected roots were reimplanted into the spinal cord or were sutured to the proximal stump in delayed 3 weeks each with 16 rats.At the different time point(3 weeks3 months6 months)through pathological examina- tion and immunohistological lechniques and nerve tracing techniqueswe examined the spinal cord and distal nerve trunk in order to observe the pathologic changes and axonal regeneration.Results Group A、C were much better than group B、D in the numberthe conformation and the degree of abatement of spinal motoneu- rons and nissl body.It is the same on the number and the development level of regenerating nerve fiber. Conclusion It had the advantage of neuronal protection and nerve regeneration that reparing the injured nerve roots earlv after nerve roots injury.

Objective To study the personality characteristics of the stagnation of liver-qi syndrome cases with Minnesota Multiphasic Personality Inventory (MMPI).Methods 20 liver-qi stagnation syndrome cases and 20 normal persons whose paired by sex and age were tested by MMPI. The scores of 13 clinical scales and the section plane of MMPI were acquired and analyzed. Results There was a significant difference in 9 clinical scales (F, Pa, D, Pt, Si, Sc, Hs, Hy, Pd) between the liver-qi stagnation syndrome cases and normal persons ( P<0.05～0.001). The scores of Hs, D, Hy, Pd in the liver-qi stagnation syndrome group were higher than the Chinese normal model. The MMPI section plane of liver-qi stagnation group presented the type of 3/1. Conclusion The patients with liver-qi stagnation have some special personality characteristics such as depression, anxiety, loneliness, indifferent and attention.

ObjectiveTo investigate the analgesic effect of TL-Ⅰ prescription.MethodsHealth ICR mouses were randomly divided into 6 groups: negative control group, positive control group, Tongtian group, large doses group,middle doses group and small doses group. The pain threshold of mouses were detected with hot plate and acetic acid writhing.ResultsTL-Ⅰ prescription can raise the threshold of pain induced by hot plate and reduce the numbers of writhing induced by acetic acid in mice, which was more significant in large doses group. ConclusionTL-Ⅰ prescription can be an effective analgesic.

ObjectiveTo investigate the sedative effect of TL-Ⅰ prescription.Methods72 healthy ICR mice were randomly divided into 6 groups: normal group, model group, positive control group, large doses Chinese materia medica group, middle doses Chinese materia medica group and small doses Chinese materia medica group. The active behavior of migraine-model-mouse was detected with tail suspension test and the analytical system of animal behavior-spontaneous movement.ResultsTL-Ⅰ prescription could prolong the quiescent time of migraine-model-mouse and shorten the active journey and time in the autonomic active box of migraine-model-mouse.ConclusionTL-Ⅰ prescription has sedative effect.

Objective To evaluate the relationship between Henoch-Schonlein purpura (HSP) accompanying renal impairment and helicobater pylori(Hp) infection.Methods This study consisted of 304 patients with HSP.The patients were divided into 2 groups(group A and group B) based on Hp infection or not(91 cases in group A and 213 cases in group B).Compared with the rates of accompanying renal impairment in 2 groups.And observed the recovery from renal impairment between the patients who were turned into negative(group C)and patients still were positive after the anti-Hp therapy(group D).Numeration data were analyzed by ?2 test.Results Group A which was with Hp infected,the accompanying renal impairment ratio was 65.9%.Group B which was without Hp infected,the ratio was 35.2%.There was significant difference between 2 groups(?2=24.378 P
