Aim To explore the role of a peroxisome proliferators-activated receptor gamma ligand,Rosiglitazone,in angiogenesis in human lung adenocarcinoma cells with reference to the regulation of vascular endothelial growth factor(VEGF).Methods Human lung adenocarcinoma A549 cell line was cultured in vitro.Expression of PPAR? and VEGF in A549 lung adenocarcinoma cells treated with different concentrations of Rosiglitazone was examined by semi-quantitative RT-PCR and immunohistochemical staining.Results PPAR? protein levels were higher in cultured A549 cells.RT-PCR and immunohistochemical staining showed that PPAR? mRNA and protein were enhanced in cells treated with Rosiglitazone in a dose-dependent manner,compared with those of untreated cells.Rosiglitazone had a potent inhibitory effect on the expression of VEGF in A549 cells dose-dependently in a range of concentrations.The effect was maximal with 10 ?mol?L~(-1) RSG and weaken over 20 ?mol?L~(-1) RSG,whereas 100 ?mol?L~(-1) RSG didnot have this down-regulation.GW9662,a PPAR? antagonist,partially blocked this effect of Rosiglitazone.Conclusions Activation of PPAR? suppresses angiogenesis in human lung adenocarcinoma.This action is probably associated with the down-regulation of angiogenic factor,VEGF,which may be modulated by PPAR?.These results suggest that PPAR? might be a novel molecular target for angiogenesis lung adenocarcinoma.

Objective To approach the design and clinical application of large anterolateral thigh flap and its effect in wound repair.Methods The flaps were designed according to the anatomical features of perforating branches in the anterolateral thigh flaps.When a flap was chipped,a thick branch or a terminal branch of original vessel was reserved,another suitable perforating branch was selected in the proximal or distal end of the flap,and then the two vessels were anastomosed to enlarge the range of blood supply.If the vessel pedicle of a flap was a musculocutaneous perforating branch,the perforating branch of anastomosis was cut at out-point of muscle.If the vessel pedicle of a flap was a intermusclar branch or a direct skin artery,the perforating branch of anastomosis was cut widely.From May 2006 to May 2012,the technique was applied in 28 patients with large skin defect of limbs.The diameters of perforating branches obtained at out-point of muscles were measured during surgery.The survival of flaps was observed after surgery and complications in donor sites were checked during follow-ups.Results There were 18 flaps whose vessel pedicle were musculocutaneous perforating branches.The branches were cut at outpoint of muscles.The diameters of these vessels were measured during surgery.They ranged from 1.3 mm to 1.8 mm with an average of 1.45 mm.All of the vessels could be anastomosed.All 28 flaps survived.All flaps survived.The areas of the flaps ranged from 22 cm × 15 cm to 42 cm × 14 cm.Artery crisis happened in 2 flaps whose vessel pedicle were musculocutaneous perforating branches.The second look operation found that the areas of artery anastomosis of perforating branches and vessel pedicles were compressed by hematoma and thrombus formed.The 2 flaps survived after the hematoma was cleared away and the vessels were reanastomosed.There were no infections.Both the donor and recipient site healed by first intention with no necrosis of flap margin.All 28 patients were followed up by 4-13 months with an average of 8 months.There were no apparent collapse deformities,muscle necrosis,declines of muscle strength and muscle hernia in the donor sites.The appearance of flaps was flat,the color was close to normal and the quality was fine.Conclusion It is a safe and effective method to repair wound surface by large anaterolateral thigh flap obtained by the modus operandi of perforating branch anastomosis.

BACKGROUND: Recently, trans-pedicle screw internal fixation has markedly improved the rigidity of spinal fixation and hence the fusion rate. But when placed incorrectly, the pedicle screw can injure the spinal cord and/or nerve roots, resulting in serious complications.OBJECTIVE: To evaluate the application value of preoperative CT scans-based navigation technique in the spinal pedicle screw internal fixation surgery.DESIGN, TINE AND SETTING: A prospective, randomized, and controlled observation was performed at the Department of Orthopedics, Peking Union Medical College Hospital, Chinese Academy of Medical Sciences between January 2006 and December 2008.PARTICIPANTS: A total of 95 patients who underwent pedicle screw internal fixation due to spine diseases were randomly assigned to a navigation group (n = 45) and a conventional group (n = 50).METHODS: In the navigation group, patients were subjected to pedicle screw insertion with the assistance of computer navigation technique and while in the conventional group, patients underwent pedicle screw insertion using the conventional anatomic landmark combined with fluoroscopy.MAIN OUTCOME MEASURES: Screw channel preparation time, excellent and good rate of screw position, and postoperative complications.RESULTS: In the navigation group, totally 206 pedicle screws were inserted under navigation guidance, with an excellent and good rate of 96.1%; and navigation could not be continued in 9 patients for a three-dimensional registration error. In the conventional group, altogether 285 pedicle screws were inserted, and the excellent and good rate was 100%. No significant difference was found between the two groups (P > 0.05). The navigation group exhibited longer screw channel preparation time than the conventional group [(360±22) seconds vs. (56+8) seconds, P < 0.01]. No postoperative complications were found in each group.CONCLUSION: The preoperative CT scans-based navigation technique produces similar accuracy of pedicle screw insertion, but markedly prolonged operation time, compared with the conventional anatomic landmarks, exhibiting limited application value in the spinal pedicle screw internal fixation.

OBJECTIVE:
To assess hearing effect of ossicular chain reconstruction with titanium ossicular replacement prosthesis during mastoidectomy with synchronous ossiculoplasty in chronic middle ear disease.
METHOD:
Retrospective reviews were performed for 139 patients who had underwent mastoidectomy and tympanoplasty with titanium ossicular replacement prostheses at the same time between 2008 and 2011. The partial ossicular replacement prostheses (PORP) were used in 91 patients and the total ossicular replacement prostheses (TORP) were used in 48 patients respectively. All patients had follow-up for 2 to 5 years. The preoperative and postoperative mean air conduction and air-bone gaps(ABG) for the four frequencies (0.5, 1.0, 2.0 and 4.0 kHz) were evaluated. The improvement of mean air conduction and ABG over the same frequencies were measured. A postoperative ABG less than or equal to 20 dB was considered a successful operation. The hearing results of titanium PORP and TORP were compared.
RESULT:
The mean air conductions were (53.97 +/- 11.32)dB and (36.80 +/- 11.68) dB preoperatively and postoperatively in PORP group. The mean improvement in air conduction was (17.17 +/- 5.79)dB. The mean ABG was (31.84 +/- 6.17)dB and (15.13 +/- 7.22)dB preoperatively and postoperatively in PORP group. The mean improvement in ABG was (17.71 +/- 5.5)dB. The difference of hearing threshold between preoperative and postoperative had statistical significance (P < 0.01). The mean air conduction were (58.05 +/- 11.35)dB and (44.53 +/- 13.15)dB preoperatively and postoperatively in TORP group. The mean improvement in air conduction was (13.52 +/- 7.81)dB. The mean ABG; were (35.67 +/- 5.73)dB and (21.48 +/- 7.01)dB preoperatively and postoperatively for TORP group. The mean improvement of hearing threshold in ABG was (14.18 +/- 7.53)dB. The difference of hearing threshold between preoperative and postoperative had statistical significance (P < 0.01). ABG less than 20 dB after operationwas happened in 68.63% of the patients (74.73% for PORP and 54.17% for TORP). There was statistically significant difference between PORP and TORP (P < 0.05).
CONCLUSION
We conclude that titanium ossicular reconstruction during mastoidectomy with synchronous ossiculoplasty give stable and excellent hearing results. We obtained better results with PORP than with TORP.
