BACKGROUND: Basso, beattie and bresnahan (BBB) score and tilt table test are associated with the height of spinal cord injury degree in study of spinal cord models. OBJECTIVE: To establish modified complete spinal cord transected rat models, and to observe effects of BBB score and tilt table test on function following human umbilical cord blood mesenchymal stem cell transplantation. DESIGN, TIME AND SETTING: The observation control experiments were performed at the Key Laboratory of Tissue Construction and Detection of Guangdong Province from April 2007 to July 2008. MATERIALS: Cord blood was collected from healthy puerperants after full-term delivery. Fifty SPF healthy adult female Sprague Dawley rats were randomly divided into group A (sham operation) (n=10), group B (spinal cord transection and phosphate buffered saline, PBS injection) (n=20), group C (spinal cord transection and hMSCs transplantation) (n=20). METHODS: Human umbilical cord blood stem cells were harvested and cultured in vitro. After incising rat dural sac, arachnoid membrane, spinal cord, bilateral wall and ventral dura mater of spinal cord were completely incised in the dural mate of spinal cord to establish complete spinal cord transected rat models. Vertebral plates were only opened in the group A. Rats in the group C were injected with human umbilical cord blood mesenchymal stem cells (6?109 -7?109L-1) at two broken ends of fractured spinal cord. Phosphate buffer saline was injected into rats in the group B. MAIN OUTCOME MEASURES: At 12 weeks after surgery, a behavioral testing was performed every 2 weeks upon each hindlimb for all animals by using the BBB scoring system and tilt table test. RESULTS: No significant difference in hindlimb motor function was detected in the group A. From the second weeks after surgery, motor function of hindlimbs was gradually recovered in the groups B and C. BBB scoring system and tilt table test showed a consistent increasing tendency in a positive correlation. From the fourth week after surgery, significant difference in tilt table test was detected between rats with BBB score

Objective To observe the efficacy of Mimics finite element analysis software in the gasserian ganglion radiofrequency treatment of trigeminal neuralgia. Methods 180 cases with primary trigeminal neuralgia and VAS score ≥8 were randomly divided into 2 groups (n = 90 each): CT group (group C) and Mimics group (group M). The preoperative skull CT image of the foramen of cranial base could be analyzed in group C. The preoperative cranial CT image could be reconstructed and analyzed by Mimics finite element analysis software in group M. The puncturing success rate, complications rate and the outcomes between two groups were recorded. Results The puncturing success rates were 100% in group M and 92% in group C (P < 0.05). 6 cases with hematoma and 1 case, which were stabbed into the oral cavity were found in group C. No puncture complication was found in group G. There was no statistically significant between the two groups (P < 0.05). The VAS score was 1.6 ± 0.3 in group C and 1.3 ± 0.4 in group G, there was no statistical significance (P > 0.05) between them. Conclusions The Mimics finite element analysis software could improve the success rate of basicranial foramen ovale puncture and reduce the occurrence rate of puncture complications. Therefore , it could be safely applied to the treatment of primary trigeminal neuralgia by gasserian ganglion radio frequency.

Objective To evaluate the changes of left ventricular(LV) 3-dimension peak displacement (3D-D) during different cardiac pacing patterns. To provide a reliable mechanical data base for the optimization cardiac pacing. Methods Cardiac pacings in open-chest Beagle canine models( n = 10) were performed using three patterns[I, e. , right ventricular apical pacing (RVA-P), LV lateral pacing (LVL-P)and LV apical pacing(LVA-P)],3D full volumetric real-time imaging were acquired in a completed cardiac cycle. The 3D-D,3D-D peak time (3D-DTc) and the standard deviation of TC(3D-DTSD) were calculated and analyzed in different pacing patterns for difference and spatial correlationship. Results ① The 3D-D of LVL-P and LVA-P state decreased compared with BASE and RVA-P state, there were significant 3D-D difference of mid anterior,mid anteriorspetal, mid interior,mid posterior, mid lateral between LVL-P and BASE, RVA-P patterns( P ＜0.05). There were significant 3D-D difference of mid anterior,mid lateral,mid posterior between LVA-P and RVA-P patterns groups( P ＜0.05). There were significant 3D-D difference of all segments in apical level between LVL-P,LVA-P and BASE, RVA-P states( P ＜0.05). ② Corrected by the heart rate,the 3D-DTC of different cardiac pacing patterns were shorter than BASE state. ③ There were no significant 3D-DTSD difference between different cardiac pacings and BASE patterns. There were significant 3D-DTSD difference between RVA-P and LVA-P patterns (P ＜ 0.05). Conclusions LV mechanical activation and synchronization could be maintained during RVA-P rather than LVA-P and LVL-P. Echocardiographic study of left ventricular 3D-D can actually reveal myocardial mechanical state during different cardiac pacings and BASE patterns.

Objective To investigate the clinical characteristics,diagnosis and treatment of congenital tracheobiliary fistula (CTBF) in children.Methods A case of CTBF admitted into the Department of Pediatric Respiration,Hubei Maternal and Child Health Care Hospital in 2016 was reported,and the related literatures were reviewed.The clinical features,diagnostic methods,treatment status and clinical outcomes of the disease were analyzed.Results The patient was 3 years and 7 months old.The main clinical manifestations were recurrent cough,pneumonia and atelectasis.CTBF was diagnosed by means of iodine oil radiography and treated with biological glue plugging under bronchoscopic guidance.So far,only 30 cases of CTBF have been reported in the English literatures,but only 2 cases in the Chinese literatures.The main clinical manifestations were cough,dyspnea,sputum or bile vomiting,aspiration pneumonia,atelectasis or emphysema.Diagnostic methods for CTBF included bronchoscopy,bronchial angiography and cholangiography,hepatobiliary scan,CT scan and magnetic resonance imaging.Except for this case treated with biological glue plugging under bronchoscopic guidance,all other patients were treated with surgery.The operation methods included fistula ligation,gastrostomy,liver resection,fistula jejunum Roux-en-Y anastomosis,hepatic hilum jejunum anastomosis,gallbladder jejunum anastomosis,etc.Only 4 cases died,and the rest of the patients recovered.Conclusions CTBF should be suspected in children with persistent chronic cough.Iodine oil radiography through bronchoscopy is a simple and feasible method for diagnosis of CTBF.Besides surgery,the lavage and the biological glue plugging method through bronchoscopy is also an effective way to treat CTBF in children without severe biliary malformation.

Objective To investigate whether a 3D printed model of the contrlateral healthy distal radius, especially its articular accuracy, helps anatomical reduction and precise reconstruction of the fractured distal radius. Methods The CT data of bilateral radii were collected from 15 normal volunteers ( 11 males and 4 females with an average age of 22. 8 years ) between November and December 2016. After 3D reconstruction of the bilateral distal 1/3 radii, solid 3D models of left radius were mirrored and generated by 3D printing. The data of right radii ( reference group ) were compared with the data of the solid 3D models of left radius acquired through a 3D scanner ( test group ) using deviation analysis. Results The maximum volume difference between the 3D printed model and the contralateral radius was 6. 86％. The average volume of the reference group was 19, 165. 82 ± 3, 250. 50 mm3 and that of the test group 19, 310. 65 ± 3, 305. 15 mm3, showing no statistically significant difference between the 2 groups ( t= -0. 941, P=0. 363 ) . The maximum surface area difference was 3. 84％ between the 2 groups. The average surface area of the reference group was 5, 075. 80 ± 549. 34 mm2 and that of the test group 5, 139. 43 ± 572. 48 mm2, showing a signifi-cant difference ( t= -2. 451, P=0. 028 ) . The 3D deviation analysis showed a mean positive deviation of 0. 37 ± 0. 10 mm and a mean negative deviation of 0. 30 ± 0. 07 mm. The maximum mean square root was 0. 65. The 3D deviation was distributed mainly within 1 mm interval, with a distribution frequency of 96. 27％. Conclusions A 3D printed model prepared by high precision equipment is accurate enough to guide reconstruction of distal radius fractures in adults. In the treatment of complex fractures of the distal radius, a 3D printed model of the contralateral healthy distal radius can be used as a reference to achieve anatomical reduction and precise reconstruction of the fractured distal radius.

BACKGROUND:The anterior cruciate ligament has unique nonlinear mechanical properties under a complex physiological loading environment.Elastin is an important contributor to the mechanical properties of the anterior cruciate ligament,but its mechanical response to the anterior cruciate ligament under axial tension is not clear. OBJECTIVE:To quantitatively analyze the effect of elastin on the tensile mechanical response of the anterior cruciate ligament. METHODS:Elastase solution and control buffer were prepared.The porcine anterior cruciate ligament samples were prepared into small-size samples and randomly soaked in 0,0.1,1.0,2.0,5.0,and 10.0 U/mL elastase solution for 6 hours,and other small samples of the same size were soaked in 2 U/mL elastase solution for 0,1,3,6,9,and 12 hours.To determine suitable soaking conditions for elastin-targeted enzymes and verify the digestive effect,histological staining was used to compare the effects of enzyme treatment on tissue structure and composition.The ligament samples were randomly divided into elastase-treated group and PBS group,and immersed in 2 U/mL elastase solution and PBS buffer for 6 hours,respectively.A mechanical tensile test was performed before and after immersion. RESULTS AND CONCLUSION:(1)The biochemical results showed that being treated in 2 U/mL elastase solution for 6 hours could reduce the elastin content by 31.1%,and had no significant effect on other mechanical-related components in the tissue.(2)The histological results showed that elastase was able to penetrate the tissue,and the loose degree of tissue increased after treatment.(3)In the mechanical results before and after treatment,the mechanical properties of the PBS group decreased significantly,only the low-tension elastic modulus increased significantly and the initial length increased significantly in the elastase-treated group.(4)The intergroup comparison results showed that there was no significant difference between the two groups in pre-treatment,but the low-tension elastic modulus,initial slopes,saturated slopes,and initial length of the elastase-treated group after treatment were significantly higher than those in the PBS group.(5)These results suggest that elastin degradation significantly affects the biomechanical properties of the anterior cruciate ligament and further complements our understanding of the structure-function relationship of the anterior cruciate ligament.
