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.

Objective To summarize and discuss the diagnostic and treating experiences of chronic pancreatitis with mass in the head. Methods Eight patients of chronic pancreatitis with mass in the head who were misdiagnosised as carcinoma of head of pancreas were analyzed retrospectively in the past 10 years. Results All the patients exhibited abdominal pain,5 of whom were with jaundice and 3 with anorexia. All the patients were misdiagnosised as carcinoma of head of pancreas before the operation,but the pathology after operation indicated chronic pancreatitis. The pancreaticoduodenectomy was performed in 5 patients,the choledochojejunostomy in 2 patients,while the exploratory laparotomy in 1 patient. After the operations,the abdominal pain was relieved in 7 patients, while 2 patients who accepted pancreatoduodenectomy suffered from pancreatic fistula,1 of whom died in the end. Conclusion It’s hard to differentiate the chronic pancreatitis with mass in the head from the carcinoma of head of pancreas before operation. If the carcinoma of head of pancreas can’t be excluded during the operation,the pancreatoduodenectomy should be performed,while the duodenum-preserving total resection of the head of the pancreas or any intra-drainage operations should be done if chronic inflammation is found in the whole pancreas with a negative result of the biopsy of the pancreas through the needle aspiration.

AIM:To observe the expression of tumor necrosis factor-alpha ( TNF- α) and its receptor I ( P55 ) in different pterygium and discuss the role of TNF-α and receptor I (P55) in pterygium.
METHODS: Immunohistochemistical staining method ( PV) was adopted to detect the expression of TNF-α and receptor I in pterygium ( 72 eyes ) and para-pterygium conjunctival tissue ( 30 eyes ) . The relationship between the expression and clinical-pathological parameters was also analyzed.
RESULTS:The positive rates of TNF-αwere 65. 3% (47/72), 26. 7% (8/30) in pterygium and para-pterygium conjunctival tissue. The positive expression of TNF-α had statistic difference between the two groups (χ2=12. 706, P<0. 01). The positive rates of TNF-α receptor I were 56. 9% (41/72), 16. 7% (5/30) in pterygium and para-pterygium conjunctival tissue. The positive expression of P55 had statistic difference between the two groups (χ2=13. 875, P<0. 01). The positive rate of TNF-αin recurrent pterygium group was higher than primary pterygium group (χ2=6. 547, P=0. 011). There had no statistically significance of the expression intensity between the two groups (F=1. 288, P=0. 393); the positive rate in advanced pterygium group was higher than quiescent pterygium group (χ2=4. 082, P=0. 043). The expression intensity had no statistically significance between the two groups (F=0. 489, P=0. 708). The positive rate of P55 in recurrent pterygium group was higher than primary pterygium group (χ2 =9. 907, P= 0. 002). There had no statistically significance of the two group's expression intensity ( F = 1. 175, P = 0. 424 ); the positive rate in advanced pterygium group was higher than in quiescent pterygium group (χ2=11. 140, P=0. 001). The expression intensity had no statistically significance between the two groups (F=0. 665, P=0. 621).
CONCLUSION:The expression of TNF-α and P55 are changing according to the development of clinical staging and onset. The expression of TNF-α and P55 may be related to clinical classification, staging and patient's working conditions of pterygium. There has no significant difference expression intensity of TNF - α and P55 in clinical staging and onset of pterygium.

Objective To investigate the iodide uptake by U251 glioma cell lines which were transfered with both human sodium/iodide symporter (hNIS) and human thyroperoxidase (hTPO) genes. Methods Recombinant adenosine virus AdTPO was constructed through cloning, recombination, packaging and amplifying. The viral titers were calculated after purification. The protein expression of AdTPO was tested by Western-Blotting and the recombinant plasmids PcDNA3. 1/hNIS were constructed. After hNIS gene was transfected into human glioma cell lines U251 through liposome, the cell lines with stable hNIS expression (hNIS-U251) selected by G418 antibiotics were defined as hNIS-U251 group. Then, hTPO was transducted into hNIS-U251 with adenosine virus (AdTPO-hNIS-U251 group). U251 cells with no plasmid were used as the control group (U251). Cultured cells from each group were studied for 125I uptake as well as 125I efflux rate. Student-Newman-Keuls in multiple range test was used. Results AdTPO-hNIS-U2.51 with stable expression was successfully established by transfecting hNIS and hTPO genes into human glioma cell lines. The 125I uptake by AdTPO-hNIS-U251, hNIS-U251 and U251 cell lines was (74 647.53 ±3605.88), (55 769.96 ±4353.26) and ( 507.67 ± 57.69 ) counts/min, respectively ( F = 836. 17, P ＜ 0.05 ). The uptake compacity by AdTPO-hNIS-U251 was 147 fold higher than that by U251 (q =55.64, P＜0.01 ) and 1.3 fold higher that by hNIS-U251 (q = 14. 17, P ＜0.01 ). 125I efflux rate was prolonged in AdTPO-hNIS-U251 group and its effective half time was 13 min. Conclusion Enhanced 125I uptake by the human glioma cell lines can be achieved with combined transfection of hNIS and hTPO genes.

Objective To biomechanically study the fixation stability of different numbers and shapes of the titanium miniplates (L-shaped and straight four-hole miniplates) in the treatment of maxillary LeFortⅠ fracture by using three-dimensional finite element method so as to provide reference for clinical treatment of the fractures. Methods Three-dimensional finite element model of maxillary LeFortⅠ fracture was established with four kinds of rigid internal fixation (RIF) methods to calculate the stress of the maxilla and the RIF as well as the displacement of the fracture segment under three kinds of occlusion.Then, the fixation stability of different methods was compared. Results Under the same occlusion condition, the decreasing order of the displacement of the fracture segment was the L-shaped plate fixation at both buttress of the maxillary and nasal maxillary zygomatic, the straight four-hole miniplates fixation at both buttress of the maxillary and nasal maxillary zygomatic, the L-shaped plate fixation at the zygomatic maxillary buttress and the L-shaped plate fixation at naso-maxillary buttress. Under the same fixation method, the decreasing order of the displacement of the fracture segment was molar occlusion, premolar oeclusion and incisor occlusion. Conclusions The fixation stability of the L-shaped plate fixation is better than the straight four-hole miniplate fixation for the treatment of LeFortⅠ fracture. Fixation at the zygomaticmaxillary buttress is better than at the naso-maxillary buttress. Use of only two miniplates to fix the LeFort Ⅰ fracture may not be stable. Molar occlusion is not good for fracture healing.
