Objective: To investigate the effects of tooth extracti on on dental arch width and alveolar bone width. Methods: D ental arch width and relevant alveolar bone width between canines, second premo lars and first molars were measured on dental casts of 20 cases with Angle II 1 malocclusion before and after tooth extraction treatment. All data were analy sed by SPSS 10.0 statistic software. Results: After treat ment, in maxilla the arch width and alveolar bone width between canines were in creased(P

A total of 52 patients with chronic lateral epicondylitis were randomly assigned into platelet-rich plasma (PRP) (n =28) or corticosteroid (n =24) group.The visual analog pain scale (VAS) and Mayo elbow score had no significant difference between two groups within 1 week post-treatment.However,VAS and Mayo elbow score improved more significantly in PRP group versus corticosteroid group at Month 1 and 6 post-treatment (P ＜ 0.05).The PRP trigger point injection treatment of elbow lateral epicondylitis achieved clinical outcomes and it was superior to glucocorticoid treatment.

Retrospective analysis was performed for the clinical data of 15 chronic insertion achilles tendinitis patients undergoing platelet-rich plasma (PRP) trigger point injection.The scores of Validated Victorian Institute of Sports Assessment-Achilles (VAS-A) and foot function index (FFI) improved greatly versus pre-treatment (all P ＜ 0.05).Tendon insertion structure inflammation decreased significantly on magnetic resonance imaging.At the last follow-up,all patients recovered normal gait and daily activity.The trigger point injection of PRP is efficacious for chronic insertion achilles tendinopathy.

Objective To observe the effects of platelet-rich plasma (PRP) gel in the treatment of [Ⅳ stage pressure ulcers.Methods A total of 12 patients with stage Ⅳ pressure ulcers were treated with PRP gel from December 2012 to December 2013 in our department.The PRP gel was formed by autologous PRP mixed with thrombin and calcium chloride.The PRP gel was applied to the wound after dressing.Time intervals between dressing were 4 days.Overall pressure ulcer improvement was assessed every week until complete wound healing.Results All stage Ⅳ pressure ulcer wound infection was controlled and fresh granulation tissue was found after 2 times of PRP gel covering.The time of ulcer wound healing were 6-10 weeks (mean 8 weeks).The times of changing the PRP gel were 16.No patients experienced adverse reactions during treatment.Conclusions PRP gel can effectively control the pressure ulcer infection and promote ulcer wound healing.

OBJECTIVE To invest igate the therapeutic effects of music combined cognitive behavioral therapy on subjective tinnitus and the changes in spectral characteristics of resting electroencephalogram(EEG) before and after treatment under eyes closed condition. METHODS 8 patients with subjective tinnitus were enrolled as experimental group including 4 males and 4 females, with a mean age of 33.57±8.52 years from 18 to 40 years, 6.00±3.63 months of illness and right-handedness. Music combined cognitive behavioral therapy included a total of 6 sessions of treatment. The initial session of the treatment aimed to establish basic trust with the patient and understand the patient's personality, tinnitus symptoms, medical history, and other basic conditions. The light music which was specially processed by mactching the frequency and intensity to the patient's tinnitus were selected as combined audio of cognitive behavioral therapy. 7 minutes of closed-eye resting state EEG, THI scale, VAS scale, and SAS scale of the patients with subjective tinnitus were collected. The last 5 sessions was a tailored relaxation therapy including training and counseling patients to understand the treatment feedback after each meeting. After 3 months of the therapy, 7 minutes of EEG, THI, VAS and SAS scales of the 8 patients were asessed. The results of 7min-EEG, THI, VAS, and SAS scales were compared in patients with tinnitus before and after treatment. In addition, 8 patients with normal hearing and without tinnitus were enrolled as control group including 4 males and 4 females, with a mean age of 21.26±7.56 years from 20 to 45 years and right-handedness. The control group underwent 7 minutes of EEG examination. RESULTS The difference between the two groups before treatment was statistically significant(t =4.404, P <0.05). The full-band(0.5-44 Hz) energy of EEG before and after treatment in 8 patients with subjective tinnitus was statistically significant(t =3.705, P <0.05), and the average power of EEG after treatment in the experimental group and the control group was similar. The THI scale(t =3.664, P <0.05) and VAS scale(t =3.265, P <0.05) were compared before and after treatment and the difference was statistically significant. The difference of SAS scales between the two groups was not statistically significant(P >0.05). CONCLUSION Music combined with cognitive behavioral therapy has a significant effect on subjective tinnitusand the closed-eye resting state of brain power can show the recovery of subjective tinnitus of patients objectively which has significance for rehabilitation.
