Objective:To study the expression of vascular endothelial growth factor(VEGF) and its receptor Flt1 in the process of mandibular fracture healing.Methods:The fracture models were made in the middle of the left mandible of 25 rabbits,then the specimens from the fracture site were taken 48 hours and 1,3,5 and 8 weeks after operation respectively. The expression of VEGF and Flt1 was detected by immunohistochemistry and in situ hybridization.Results:VEGF mRNA, VEGF and Flt1 were detected in many kinds of cells in the fracture site from 48 hours to 8 weeks after fracture, and high expression of VEGF and Flt1 were detected from 1 to 3 weeks after facture.Conclusions:VEGF and Flt1 are expressed through the process of fracture healing, VEGF may play important role in the process of blood vessel rebuilding after fracture.

Objective: To study the classification of congenital velopharyngeal insufficiency(CVPⅠ).Methods:30 patients with CVPI were divided into 2 groups.The patients in group I were with submucous cleft palate,those in group Ⅱwere without noticible abnormality.A11 patients received oral examination and 1ateral cephalogram examination. ANS-PNS(1ength of hard palate),PNS-U(velar 1ength),PNS-PPW(pharyngeal depth),SPT(thickness of soft palate),need ratio, elongation and upward angle of soft palate were measured. Results:PNS-U was shorter and PNS-PPW was longer in the patients than in the health controls (P

Rat lung microvascular endothelial cells (LMVEC) were cocultured with rat pulmonary arterial smooth muscle cells (PASMC). The cultures were divided into 5 groups: normal group (N), lipopolysaccharide (LPS) 2h (L 2), LPS 8h (L 8), LPS 16h (L 16 ), and LPS 24h (L 24 ). The activity of IL 6 in LMVEC and PASMC supernatants was determined by radio immunity method, and the expression level of IL 6 mRNA in LMVEC was detected with RT PCR. The results showed that the activity of IL 6 in LMVEC and PASMC was enhanced by LPS at L 2, reaching the higher level after 8 hour stimulation. Furthermore, the activity of IL 6 was stronger in homotypic groups than that of coculture groups. The expression of IL 6 mRNA in LMVEC was increased in L2 group, and highest in L6 group, but lowered in L12 group, though it was still stronger than that of N. It suggest that IL 6 mRNA and the activity of IL 6 in LMVEC and PASMC were enhanced in both homotypic and coculture groups by LPS. And the mRNA level and activity of IL 6 were higher in homotypic groups than that of coculture groups.

Objective To analyze the safety and efficacy of early diet after laparoscopic resection of colorectal cancer.Methods A prospective study of 128 patients suffered laparoscopic surgery of colorectal cancer was done in our hospital.According to whether the adoption of early diet program,patients were divided into early oral group (EOF group,n=54)and traditional oral diet group (TOF group,n=74).Age,gender,preoperative nutritional status and other basic factors and postoperative ambulation time, postoperative hospital stay time,the number of cases the use of analgesics,complications of two groups were analyzed statistically. Results The first time of postoperative ambulation time and postoperative hospital stay time of EOF group were significantly re-duced compared TOF group [(1.2±0.8)d vs .(2.5±1.3)d]and [(3.2±1.4)d vs .(5.3±1.6)d](P <0.01).Conclusion Early diet after laparoscopic resection of colorectal cancer is good for patients fast recovery,and postoperative complications of two groups are similar.

Background and purpose:Brucine is one of the active components from Strychnos nux vomica,with signifi cant analgesic,anti-inflammatory and platelet-aggregating inhibitory properties.Due to its cytotoxic effect,the anti-tumor effect of brucine has increasingly been appreciated.In this study,we investigated the impact of brucine on A549 cells proliferation,apoptosis as well as the underlying mechanisms.Methods:MTT assay was used to examine the cell viability,flow cytometric analysis and fluorescent microscope were applied to examine cell apoptosis,ELISA method was used to examine the effect of brucine on PGE2 release from A549 cells and RT-PCR analysis was used to measure mRNA content,western blotting analysis was used to measure protein expression and luciferase activity was detected to examine the effect of brucine on COX-2 promoter activity.Results:Brucine was able to suppress the proliferation of A549 cells and induce cell apoptosis to time-dependent and dose-dependent manner.To understand the mechanisms,COX-2 was identifi ed to be an important target molecule involved in the apoptosis induced by brucine because brucine could suppress the COX-2 mRNA,protein expressions as well as PGE2 release in A549 cells in a timedependent manner.Furthermore,overexpression of COX-2 abrogated brucine-induced cell apoptosis,in contrast,when A549 cells were transfected with COX-2 siRNA,the apoptotic effect of brucine was dramatically enhanced.Further analysis revealed that brucine was able to suppress COX-2 transcriptional activation.Conclusion:Brucine was able to induce lung cancer apoptosis via downregulation of COX-2.

Extended hemilaminectomy was performed in the treatment of compression of the cervical spinal cord produced by ossification of the posterior longitudinal ligament, multilevel degeneration and protrusion of the intervertebral discs and simple spinal canal stenosis. The results showed that with this operation the cross sectional area of the spinal canal was enlarged by 50% of the original, and the sagittal diameter lengthened 2,5mm postoperatively, so the compression of the. spinal cord was relieved. Since the function of the spinal process, the supra-and interspinal ligaments and the structure of one side of the lamina were preserved, mechanical stability of the cervical spine was maintained.

OBJECTIVE To investigate the relation of cyclooxygenase-2 (COX-2) and vascular endothelial growth factor (VEGF) expression with cervical lymph metastases in papillary thyroid carcinoma. METHODS The expression of COX-2 and VEGF in 79 specimens of papillary thyroid carcinoma were evaluated with SP immunohistochemical methods. In all the 79 cases, there were 46 cases with cervical lymph node metastases and 33 cases without cervical lymph node metastasis. RESULTS The positive expression rates of COX-2 and VEGF in the cases with cervical metastases were 81.6 % and 86.8 % respectively, and in the cases without cervical lymph metastases were 54.5 % and 66.7 % respectively. There was a significant difference in the positive expression rates of COX-2 and VEGF between two groups (P

Objective To compare the effect of mediastinal lymph node dissection by video -assisted thora-coscopic surgery (VATS)with thoracotomy in the treatment of lung cancer.Methods 96 patients with non -small cell lung cancer were collected.Patients undergoing VATS were matched with those undergoing thoracotomy in terms of gender,age,clinical tumor stage,tumor location and surgical procedure.Results After matching,48 patients in VATS group and 48 patients in open group were eligible for analysis.In the VATS and open groups,the mean total numbers of dissected lymph nodes were (27.2 ±7.4)and (28.8 ±10.6)(P =0.507),the numbers of N1 nodes were (9.4 ±4.0)and (8.3 ±4.6)(P =0.323).And the number of N2 nodes was similar between the VATS and open group [(18.5 ±6.9)vs (21.3 ±9.9),P =0.201].No significant differences were observed between the two groups(all P >0.05 ).But the days of the postoperation and the chest tube indwelling in thoracotomy group were (8.1 ±3.9)and (7.3 ±4.4)days,which in the VATS group were (6.8 ±3.5)and (5.6 ±3.5),the VATS group had more advantages than the thoracotomy group(P <0.05).The intraoperative blood loss more than 400mL and peri-operative blood transfusion rate of the thoracotomy group were 27.38% and 25.00%,those of the VATS group were 7.03% and 8.60% respectively,which in thoracotomy group were higher than the VATS group.Conclusion Under-go our retrospective study,after mature VATS to treat lung cancer,with regard to the number of the dissected lymph nodes,VATS lobectomy can achieve complete mediastinal lymph node dissection compared with the traditional approach.There are more advantages by VATS in the complications.
