OBJECTIVETo investigate the clinical experiment of cortical screw in the treatment of tibiofibular syndesmosis separation together with ankle fractures.
METHODSFrom March 2008 to May 2012,42 patients with tibiofibular syndesmosis separation were treated with cortical screw, including 20 cases in the left and 24 cases in the right. All the patients had closed injury. According to Lauge-Hansen classification, there were 18 cases of supination-external rotation, in which 4 patients with injuries belong to type II, 8 patients with injuries belong to type III, 6 patients with injuries belong to type IV; 14 cases of pronation-external rotation, in which 6 patients with injuries belong to type III, 8 patients with injuries belong to type IV; and 12 cases of pronation-abduction, in which 4 patients with injuries belong to type II, 8 patients with injuries belong to type III. According to injury of ankle, 4 patients had injuries in one ankle, 28 patients had injuries in 2 ankles, and 12 patients had injuries in 3 ankles. All the patients were diagnosised definitely in sight of medical history, checking-up, iconography. The clinical effects were evaluated based on Baird-Jackson score and activity degree of ankle.
RESULTSAll the patient were followed up, and the duration ranged from 11 to 23 months, with an average of 15.7 months. No postoperative wound infection, nonunion, and tibiofibular syndesmosis separation again and other complications occurred. Postoperative Baird-Jackson score exhibited 91.56 ± 6.26 (75 to 99), and 26 patients got an excellent result, 10 good, 6 poor and 2 bad. One patient had nail broken after operation,and got good function after removing broken nail without external fixation. Other 1 patient had osteoarthritis to 1 degree, and got better result with the treatment of physical therapy and intra-articular injection.
CONCLUSIONCortex screw is the effective treatment for tibiofibular syndesmosis separation. Clear diagnosis, delicate operation and postoperative reasonable functional exercise are primary factor of prognosis.

Objective:Through histological analysis, immunofluorescence staining, electrophysiological detection and Sensory and motor function evaluation to investigate the effects of 3D printed hydrogel scaffold combined with bone marrow mesenchymal stem cells (BMSCs) in promoting functional recovery of spinal cord injury.Methods:10% GelMA hydrogel and 10 6 U stem cell suspension were prepared into bioink of appropriate concentration to construct the biomimetic spinal cord scaffold through 3D printing platform. The scaffold was placed in the medium and cultured in an environment of 37 ℃ CO 2 incubator. The microstructure of the scaffolds and the distribution of BMSC in the scaffolds was observed by scanning electron microscope. CAM/PI staining and confocal microscopy were used to observe the survival of stem cells in the scaffolds and determine the biocompatibility of the scaffolds. The scaffolds were implanted into the subcutaneous tissues of the back of rats, and the subcutaneous tissues were determined by HE staining to detect the immunogenicity of the scaffolds. After the rat model of hemicytoma defect was made, stents were transplanted for treatment, and confocal microscopy was used to evaluate the regeneration of neurons and axons in local area of spinal cord injury. At the same time, BBB score was used to evaluate motor function, mechanical pain score was used to evaluate sensory function, and surface electrode detection method was used to evaluate electrophysiological recovery weekly. Results:The long spindle shaped BSMC were uniformly distributed in the scaffold with a loose reticular structure. The scaffolds had good biocompatibility, and the cell survival rate of the prepared scaffolds reached 96% after 24 hours of printing. After 28 days of subcutaneous transplantation, the immune rejection was mild and immunogenicity was low. It was shown that the regenerated spinal cord tissue in the treatment group was significantly increased compared with the control group, which was widely distributed with cells after 28 days by HE staining. It was confirmed that part of the regenerated spinal cord tissue was neurons by immunohistochemical staining.Compared with the injured group, the regeneration of neurons and axons in the treatment group were significantly increased by immunofluorescence staining and confocal microscopy. In the treatment group, the BBB score recovered to 10 points, while the control group only recovered to about 1 point in the first week, which was statistically significant. And it recovered to 17 in the fourth week, while the control group only recovered to about 4 point in the four week, which was statistically significant. The Angle of inclined plate support of the treatment group was restored to 40 degrees, while it was only restored to 22 degrees in the control group. The pain threshold of the treatment group decreased to 18.5 points, which was not statistically different from that of the control group. The latent recovery effect of electrophysiology in the treatment group was the same as that in the sham operation group and better than that in the control group.Conclusion:3D printing hydrogel scaffold with loose network structure is suitable for cell proliferation. It has well biological survival, low cytotoxicity and low immunogenicity, which promoted neurons and axons to recovery and extend so as to effectively promote the recovery of motor function, sensory function and neural signal transmission rate after spinal cord injury.

ObjectiveTo compare detection rate of pulmonary nodules and the radiation doses of digital tomosynthesis (DTS) and MSCT chest scanning by using the anthropomorphic chest phantom which containsthermoluminescent dosimeters( TLD ) and simulated pulmonary nodules.Methods The radiation doses of DTS and MSCT scanning were measured by using the anthropomorphic chest phantom which contains 45 TLD and simulated pulmonary nodules.The radiation doses of najor organs were converted into effective dose ( ED ). Three radiologists of different clinical experiences independently reviewed and recorded the density,diameter and position of pulmonary nodules.The sensitivity of nodule detection by DTS and MSCT were compared by Fisher exact test and Chi-square test. The paired t test was conducted to analyze the dose levels of DTS and MSCT.ResultsThe sensitivity of detection nodule by DTS and MSCT were 66.7% (30/45) and 91.1% (41/45) respectively.Statistically significant difference between the two examinations existed ( x2 =8.073,P < 0.05).The sensitivity of detection - 650 HU ground glass opacity pulmonary nodule by MSCT and DTS were 93.3% (14/15) and 73.3% (11/15) respectively.There was no significant difference between DTS and MSCT ( P > 0.05 ).The sensitivity of detection - 800 HU ground glass opacity nodule and ground glass opacity nodule (d < 8 mm) by DTS were 33.3% (5/15) and 16.7% (2/12) respectively,which were lower than those by CT[80.0% (12/15) and 66.7% (8/12)].The radiation doses of DTS for various organs in the chest were lower than those of CT. Statistical significant difference between DTS and MSCT existed ( lung t =19.69,thoracic vertebral t =30.01,heart t =16.33,liver t =5.06,breast t =9.43,thyroid gland t =8.05 ;P < 0.05).The effective doses of the DTS and MSCT were 0.65 and 7.71 mSv respectively.ConclusionsThere is no difference between the DTS and MSCT in the detection rate of -650 HU ground glass opacity nodule.For detecting the ground glass opacity nodule ( - 800 HU) and ground glass opacity nodule (d < 8 mm),MSCT is superior to DTS. However,the radiation dosage of DTS is 8.41% of the MSCT scanning.
