RESUMEN
BACKGROUND:Deluxe-PS knee prosthesis is designed based on the anatomical characteristics of the Chinese peoples’ knee joint, especial y the morphological features of femoral condyle. The distance between median and lateral knee prosthesis femoral condyle is less than that of the imported prosthesis for 3.5 mm. OBJECTIVE:To explore the short-term efficacy of Deluxe-ps knee prosthesis in simultaneous bilateral total knee arthroplasty. METHODS:Fifteen knee osteoarthritis patients (30 knees) were included as the experimental group, and treated with simultaneous bilateral knee arthroplasty by Deluxe-ps knee prosthesis. Twenty patients (40 knees) in the control group were treated with simultaneous bilateral knee arthroplasty by PFCSigma knee prosthesis. The knee society score, hospital for special surgery knee score and knee joint range of motion were compared between two groups;the operation time and the intraoperative blood loss were compared between two groups. RESULTS AND CONCLUSION:The patients in both groups were fol owed-up for 12 to 24 months, with an average of 16 months. Postoperative knee pain was relieved, and the joint function was recovered satisfactorily. The knee society score, hospital for special surgery knee score and knee joint range of motion in two groups were improved significantly after treatment (P0.05), and there was no significant difference in intraoperative blood loss between two groups (P>0.05), while there was significant difference in operation time between two groups (P<0.05). The results showed that the short-term effect of Deluxe-ps knee prosthesis in simultaneous bilateral total knee arthroplasty was satisfied.
RESUMEN
[Objective]To detect the expression of tumor necrosis factor-?(TNF-?)and interleukin-18(IL-18)protein in herniated intervertebral disc,and discuss the role of TNF-? and IL-18 protein in the course of the intervertebral disc degeneration and to clarify the mechanism of the lumbar intervertebral disc degeneration and herniation. [Method]Forty nine specimens were studied from December 2005 to April 2007 in the First Affiliated Hospital of Shihezi Medical College.Experimental group contained thirty-four herniated intervertebral disc and control group contained fifteen discs,which were collected from the patients with spine fracture or autopsy.The specimens were divided into two parts,one part was fixed in 10% formalin about 24 hours and was embedded in paraffin.Four ?m serial sections and S-P method were used.The sections were stained with TNF-? and IL-18 monoclonal antibodies,and the results were observed by OLYMPUS microscope.Another part was changed into well-distributed liquid,which was determined by Elisa method respectively,in order to detect density of TNF-? and IL-18 protein.Software SPSS 13.0 was used for statistical analysis.[Result]1 TNF-? and IL-18 protein were expressed mostly in cytoplasma.The expression of IL-18 in the experiment group was obviously higher than in the control group.There were statistical significances(P
RESUMEN
[Objective]To study the role and the effect of establishing the plan of meeting emergency in the rehabilitation and reestablishment of high-octane body hurt.[Method]Eighty six patients of high-octane body hurt were collected from Shi He Zi people's hospital during 1998 to 2007.According to Gustilo-Anderson categorize of open fracture and mark of ISS,high-octane body hurt can be divided into three parts.Meanwhile,different part can be taken different methods to rehabilitate and reestablish.Therefore,we can analyze pertinence between cure principle and curative effect.[Result]Eighty three patients were observed during the period of fifteen and thirty-three months,the average were nineteen months.Five of them contracted double floating knee injury,and their knee joint appeared anchylosis,abnormality and function failure afterfracture healed up.We did one-off knee joint release while extracting internal fixation,and used CPM machine to assist exercise.Fortunately,the function of knee joint could be renewed.Another five patients' fracture did not heal up very well.However,after experiencing the apply of oneself bone autograft,fracture could be healed up perfectly.The time of allograft bone union ranged from five to sixteen months,the average time were 7.5 months.There are three patients contract paraplegia,and three patients dead.By autopsy,some of them belongs to multiple fracture and multiple viscera burst.Mortality was 3.48%.[Conclusion]By establishing the plan of meeting emergency of high-octane body hurt,using the Gustilo-Anderson categorize of open fracture and mark of ISS,we can systemic classify damage degree,and make scientific treatment by stages,therefore,attaining our goal of early diagnoses,early treatment,and decreasing mortality and decreasing the proportion of disabled.After all,the plan of meeting emergency plays an essential role in traumatie surgery.
