Twety dogs were used to study a high Power Co_2 laser scapel for hemisplenectomy and traumatic rupture of the spleen by temporary occlusion of the spleen pedicle. The laser scapel with its point power of 160-200 w was used for a focusing cut and for stopping bleeding by the laser beam beyond the focus. The wound surface could be dried and coking good, without injecting adrenaline into the splenic artery. All the dogs survived after the experimental investgation and no infection or any more Post-oPerative bleeding was found. The spleen membrane was formed on the section of the spleen 1 year after operation. Compared with other operations for keeping the organ of spleen, this method safer and more reliable. It could be used in clinical practice with success.

Different genotypes have been identified by genolineage analysis and gene study. This study reviews the literatare on the classification,clinical features and pathogenesis of spinocerebellar ataxia.

AIM and METHODS: To explore the role of telomerase reverse transcriptase (TERT) in monocrotaline-induced pulmonary hypertension (PH), TERT was investigated by using immunohistochemistry and image analysis on the chronic PH induced by MCT in Sprague-Dawley rats. RESULTS: TERT was positive in pulmonary vascular smooth muscle cells, bronchial smooth muscle cells and chondrocytes in normal group. TERT in MCT group was more positive in pulmonary vascular smooth muscle cells and bronchial smooth muscle cells compared with normal group. CONCLUSION: Over expression of TERT in pulmonary vascular smooth muscle cells and bronchial smooth muscle cells is related to MCT-induced PH.

[Objective] To evaluate the curative effect of anterior cruciate ligament(ACL)reconstruction for remaining anteromedial or posterolateral bundle and ruptured fiber.[Method]Among 89 cases of ACL rupture,there were 32 cases of sports injury,24 cases training injury,23 cases traffic accidents and 10 cases sprained in daily life.ACL ruptured at the notch of the femur in 24 cases,and at the intercondyle of the tibial in 28 cases.Thirty-two cases were reconstructed with quadri-bundle Hamstring tendon knot press-fit technique and 20 cases were reconstructed with quadriceps tendon press-fit technique with autogenetic patellar bone.ACL anteromedial bundle(AMB)ruptured in 14 cases and posterolateral bundle(PLB)ruptured in 23 cases.The intact bundle and the remnants of ACL were preserved.AMB and PLB were reconstructed with double-bundle Hamstring tendon knot press-fit technique in 37 cases.Absorbable interference screws were used at the tibial tunnel and sutured tendon was knotted across the tibial bone bridge.[Result]The average duration of follow-up were 25 months(14-37 months).Lysholm knee function score increased by 27.7 scores,from average 67.5 scores of pre-operation to average 95.2 scores at the end of the follow-up.Rulermetr examination tibial translation was 4 mm?2 mm in 72 cases and 6 mm?3 mm in 17 cases.Lachman test was negative in 79 case,weakly positive in 8 cases and positive in 2 cases.The function of the knees were improved and the stabilization was strengthened after operation.According to knee therapeutic effect evaluation criterion,76 cases were excellent and 13 cases were good.[Conclusion]To keep the remaining of anteromedial or posterolateral bundle and ruptured fiber for ACL reconstruction is beneficial for the graft revascularization or healing,and is helpful for the position sense or rehabilitation.

Objective: The study was designed to observe the effects of alanyl-glutamine (Aln-Gln) dipeptide on postoperative intestinal permeability and systemic inflammatory response.Methods: A prospective,randomized and controlled trial was taken.20 patients who underwent abdominal surgery were randomized into two groups: study group (intravenous administration of Aln-Gln dipeptide,0.5 g /(kg·d),for 4 days,n=10) and control group (equal normal saline as placebo,for 4 days,n=10).Temperatures,heart rates and respiration rates of all patients were daily recorded during administration.The white blood cell counts ,serum concentrations of glutamine (Gln),diamine oxidase (DAO) and interleukin-6(IL-6) and urine lactulose/mannito (L/M) ratio were measured before and after operation.Results: Serum Gln concentration was significantly decreased in control group and increased in study group on postoperative day 5.Urine L/M ratio,serum concentrations of DAO and IL-6 were significantly increased in control group and decreased in study group.The morbidity of SIRS was significantly decreased in the study group and the score of SIRS was also lower than in the control group.Conclusions: Administration of Aln-Gln dipeptide can increase the level of serum Gln,decrease the intestinal permeability,maintain the intestinal barrier and attenuate the systemic inflammatory response in the early period of postoperative patients.Aln-Gln dipeptide can be used in the fast track surgery to help patients recover rapidly.

[Objective]To explore the effects of extracorporeal shock waves(ESW) therapy on tendon-bone healing after reconstruction of the anterior cruciate ligament(ACL).[Method]Animal model of reconstruction of the anterior cruciate ligament in 18 healthy F/M New Zealand white rabbits(2～3 months old) were established using digital long extensor tendon and randomly classified into 2 groups.The ESW group was given extracorporeal shock waves therapy on 24 hours after reconstruction of the anterior cruciate ligament while the control group with only reconstruction of the anterior cruciate ligament but no more therapy.All animals were sacrificed at 2、4、8 weeks after operation for histological examinations.The specimens were stained with hematoxylin-eosin and Masson trichrome to investigate pathology change of the tendon-bone healing tissue.The ink intravascular injection was used to observe the neo-vascularization of tendon-bone healing tissue.[Result]The histological examination revealed that at 4 weeks after operation,the ESW group,tendon-bone interface was filled with proliferated fibroblasts and chondroblasts,the collagen fibers were obviously increased and regularly arranged.At 8 weeks after operation,the healing tissue at the bone-tendon interface had developed into dense connective tissue,the collagen fibers were formed in abundance and the perpendicular collagen fibers were regularly and longitudinally arranged.The transition zones of collagen fibers,fibrocartilage and bone(the structure alike a direct ligamentous insertion) occurred in the local region of tendon-bone interface.The histological observations showed that the tissue healing at tendon-bone interface of the ESW group were quicker than those of the control group.The proportion of neo-vessels at the tendon-bone interface of the ESW group were significantly higher than those of the control group at 4 and 8 weeks after operation(respectively P=0.028,P=0.008).[Conclusion]Extracorporeal shock wave treatment can significantly improve the tendon-bone early healing after reconstruction of the anterior cruciate ligament in rabbits.
