Objective: To study the mandibular bilateral sagittal split ramus osteotomy (BSSRO) with bicortical screws rigid internal fixation(RIF) with the three-dimensional finite element method, and supply directions for clinic practice.Methods:CT scanned technology and the finite element software (Ansys) were used to establish the three-dimensional finite element model of BSSRO with bicortical screws RIF. The stress distribution of the mandible and the RIF and the displacement of split mandible were calculated under three kind of occlusion situation.Results:Under the same kind of occlusion situation, the stress and displacement of the split mandible with single upper screws fixation was higher than that with the reverse "L" screws fixation, the stress and displacement of the split mandible with 2.0 mm diameter screws fixation was higher than that with 2.7 mm diameter screws fixation. With the same kind of fixation method, the stress and the displacemen of the mandible under the incisor occlusion was the highest.Conclusion:The fixation distance, position, distribution angle of the bicortical screws all have effects on the fixation stability. The patient should avoid the incisor occlusion after the surgery.

OBJECTIVE: To establish a validated infrared spectrum method coupled with cluster analysis, principal component a-nalysis and discriminant analysis for identifying different kinds of Syngnathus. METHODS: Fourier transform infrared (FTIR) spectrometer was performed on the ethanol extracts from 33 samples of Syngnathus collected from different geographical locations. Similarity analysis and cluster analysis were used to establish the reference fingerprint spectra, and principal component analysis and discriminant analysis were used for identifying different kinds of Syngnathus. RESULTS: The experimental results indicated that the samples of same species had the similar characteristic peaks of infrared spectra and could be clustered together. Based on the result of principal component analysis, the absorption peaks(3010.4-3006.5 cm-1, 1745.3-1741.4 cm-1, 1467.6-1463.7 cm-1, 1417.4-1413.6 cm-1, 1168.7-1164.8 cm-1, 723.2-719.3 cm-1, 2925.5-2919.7 cm-1, 2854.2-2850.3 cm-1) were the main characteristic peaks and were used to develop the discrimination function for distinguishing different species of Syngnathus. The accuracy of the discrimination function could reach 98.75%. The established method in the experiment had a good stability, precision and reproducibility, and was a very reliable and useful method for distinguishing different species and assessment of the quality of Syngnathus. CONCLUSION: The established IR fingerprints of Syngnathus's ethanol extracts coupled with mathematical statistics theory could be applied to identify different kinds of Syngnathus. But more importantly, the research job provides a new thought for traditional Chinese medicine identification by using mathematical model.

OBJECTIVETo explore the clinical effects of minor bone anchors and palmaris longus tendon graft in treating chronic mallet fingers deformity.

METHODSFrom January 2008 to June 2013, 26 patients with chronic mallet fingers deformity were treated with minor bone anchors and palmaris longus tendon graft. There were 18 males and 8 females, aged from 18 to 52 years old with an average of (32.0±1.3) years. Among them, 8 cases caused by machine injury, 6 cases by fall injury, 6 cases by sprain from fight, 4 cases by tendon spontaneous rupture, 2 cases by knife trauma. There was no tendon attachment of extensor tendon check in 16 cases, and with 0.3 to 0.5 cm tendon attachment in 10 cases. All patients had the flexion deformity and the disability of dorsiflexion activity. During operation, the distal interphalangeal joint was fixed in 10° to 20° dorsiflexion by a Kirshner wire, the minor bone anchor was used to reconstruct the extensor tendon insertion, the palmaris longus tendon slice was transplanted the decayed area of extensor tendon insertion. Four weeks postoperatively, the Kirshner wire was removed and the plaster external fixation was used, and the patient began function exercises. Postoperative complications were observed and fingers functions were assessed according to Dargan standard.

RESULTSThe patients were followed up from 6 to 14 months with an average of (5.0±0.3) months. Wound superficial infection occurred in 2 cases, the skin pressure ulcer in 2 cases, joint activities disability in 1 case; these symptoms got improvement after symptomatic treatment. Traumatic arthritis occurred in 2 cases, 1 case was improved after treatment, and 1 case had chronic pain for a long time. No internal fixation loosening or breakage and tendon rupture were found. According to Dargan standard to evaluate the finger function, 17 cases got excellent results, 8 good, and 1 poor.

CONCLUSIONIt is an effective way to treat the chronic mallet finger deformity using minor bone anchors and palmaris longus tendon graft, and the method has advantages of reliable fixation, easy operation, satisfactory effect and less complication.
