Objective To design and apply a kind of controllable enema input apparatus in patients with spinal cord injury (SCI). Methods 20 SCI patients with chronic constipation were included. Their defecation time, nature of defecation and usage of enema of 5 times of defecation were recorded before and after using the new apparatus. Results There were significant differences in the defecation time, nature of defecation and usage of enema before and after using the new apparatus (P<0.05). Conclusion The application of the new controllable enema input apparatus may shorten the defecation time, improve the nature of defecation, and reduce the usage of enema in SCI patients with chronic constipation.

Objective: To evaluate the effect of perfusion of pulmonary artery using hypothermic protective solution on the inflammatory response of lung during cardiopulmonary bypass. Methods: 40 children with TOF were divided into control group (n=20) and protective group (n=20). The basic parameters (age, weight, C/T ratio, oxygen saturate) were not different between both groups. In control group, the operation was performed using routine approaches. While in protective group pulmonary artery were infused with 4℃ protective solution during CPB. Plasma TNF-?, IL-6 and IL-8 of tracheal suction was measured. Lung biopsy specimens were obtained after operations for study on histological changes. At same time, patients' pulmonary functions and clinic index were monitored. Results: TNF-? was lower in protective group when compared with control group immediately and at 24h after operations (P

[Objective]To study the therapeutic effect of recombinant erythropoietin for contusion injury of spinal cord.[Method]Contusion injury of spinal cord was caused by weight dropping in 24 New Zealand rabbits.Twelve hours after injury,the rabbits in control group were given natural saline intravenously and rabbits in low,mediate and large-dose group were given rh-EPO 100 IU/kg,500 IU/kg and 1000 IU/kg respectively.Neurological status of lower limbs were scored at 24 hours,48 hours and one week after spinal cord injury.All rabbits were killed one week after injury and spinal cords were stained by HE and caspase-3 method.Electronic microscopy was used to evaluate ultrastructural injury.[Result]The neurological scores of EPO treated groups were significantly higher than that of control group.HE and Caspase-3 immunohistochemistry showed that histological and ultrastructural damage of EPO treated groups were less severe than that of control group.The caspase-3 positive neurons were significantly fewer than that of saline treated group.There was no significant difference of therapeutic effect between mediate and large-dose EPO treated groups.[Conclusion]Rh-EPO administered 12 hours after contusion injury of spinal cord could lessen histological and ultrastructural damage,prevent apoptosis of neurons and promote neurological recovery of spinal cord.Mediate dose of rh-EPO is the appropriate treatment choice for spinal cord injury.

Objective: The aim of this study is to review the experience of using bidirectional Glenn shunt without cardiopulmonary bypass(CPB). Methods: Fifty-eight patients underwent bidirectional Glenn shunt without CPB between May, 2000 and September, 2001. The age was (3.65?1.59) years and the weight was (13.6?4.0) kg. The procedure consists of establishing temporary bypass with cannulae placed in the SVC and right auricular appendage for venous drainage and transection of right SVC. The cardiac end of the SVC is overseen. The cranial end is anastomosed to a longitudinal incision in the superior margin of the right pulmonary artery with absorbable running suture. The anterior wall of the anastomosis is widened with pericardium patch. Results: There was no operative mortality. Five cases had postoperative complications including coma in 1 and chylothorax in 4. The mean SVC crossclamp time was (48?15) mins. The preoperative oxygen saturation and CVP were 0.75?0.09 and (12.8?2.3) mmHg, respectively. While the postoperative oxygen saturation and CVP were 0.93?0.05 and (16.5?2.9) mmHg, respectively. The drainage was (145?103)ml. The average mechanical ventilation time was (13?7) hrs. The mean postoperative hospital stay was (10?5) days. Conclusion: Bidirectional Glenn shunt without CPB is a safe and reliable method, for complicated congenital heart diseases children with inadequate pulmonary blood flow when anatomic and primary physiological correction are not suitable.

Objective To evaluate the clinical value of multi-slice spiral CT in diagnosing tracheobronchial foreign bodies in chil-dren.Methods 139 patients with airway foreign body confirmed by bronchoscopy were examined with 128-slice spiral CT,and then the CT data was reconstructed by using multiple-planar reconstruction(MPR),curved planar reconstruction (CPR),volume render-ing(VR),minimum intensity projection(MinIP)and virtual endoscopy (VE).The CT results were compared with bronchofibersco-py findings.Results Among the 139 cases,the foreign bodies located at trachea in 13 cases,right bronchia in 75 cases,left bronchia in 48 cases,and bilateral bronchia in 3 cases.137 cases (98.6%)were correctly diagnosed,and 2 cases (1.4%)were missed on CT.Although the difference of the results at trachea and right main stem bronchus was statistically significant (P <0.05),the over-all results was not significant difference between CT and bronchoscopy examination (P =0.340).Associated findings included em-physema in 74 cases,pneumonia in 48 cases,atelectasis in 22 cases,mediastinal displacement in 57 cases,lung interstitial emphyse-ma in 4 cases,pneumomediastinum and pneumoderma in 4 cases,bronchiectasis in 2 cases,and pleural effusion in 4 cases.Conclu-sion MSCT and its postprocessing techniques can accurately and intuitively display the tracheobronchial foreign body and complica-tions,which has important value for clinical application.

Objective To evaluate the long term results of coral bone used in anterior cervical interbody fusion. Methods The 180 patients (126 males and 54 females) who had undergone anterior interbody fusion in our hospital were followed up for 6 years. Their long-term imageological data, including changes in interbody height, interbody angle and range of movement, were analyzed and compared. Results In all the cases a solid fusion was achieved between coral reef and vertebra. The fusion was evaluated as successful in all the 180 patients. Conclusion The coral bone spacer provides the same solid fusion as autografting with iliac crest does.

Objective To study the inhibitory effects of stachyose on the hyperacute rejection in pig-to-human heart xenotransplantation.Methods A pig-to-human xenogeneic heart transplantation model was established based on an in vitro free heart blood perfusion system.The pig hearts were di- vided into two groups:group A(pig hearts treated with human blood perfusion as control)and group B(pig hearts treated with human blood plus stachyose perfusion).After perfusion for 1h,the heart xenografts were examined for deposit of lgG and IgM by immunohistochemistry and pathological analy sis.Results The mean survival time of perfusion hearts in groups A and B was(9.5?2.5)min and (46.8?8.1)min respectively(P
