Data of 39 patients (51 knees) undergoing total knee arthroplasty (TKA) in the Department of Orthopaedics,Fourth Affiliated Hospital of Guangxi Medical University between October 2001 and March 2008,were analyzed retrospectively,including 6 males (6 knees) and 33 females (45 knees) aged 59-72 years. Among the 39 cases,there were 35 cases of osteoarthritis,2 of rheumatoid arthritis,1 of osteoarthritis and pigmented villonodular synovitis,and 1 of advanced tuberculosis. Different degrees of pain,swelling,genu valgum,genu varumand and functional impairment of knee joints were found in all cases. The prosthesis adopted included 3 knees of DePuy,10 of Stryker,3 of Link,5 of Zimmer,7 of Taiwan Unite,and 23 of Pulus (made in China). Among all the cases,47 knees were treated by posterior stabilized prosthesis,and 4 knees were treated with posterior cruciate ligament-retaining TKA. Careful medical examination and evaluation were performed to control blood sugar level before operation; the operation duration was shortened as possible. Reasonable proposals were formulated to prevent the postoperative infection and deep venous thrombosis. Clinical data were analyzed using the HSS score standard. All patients were followed up for 6-57 months. No deep infection,prosthetic loosening or death was found. Postoperatively,2 patients (2 knees) developed cutaneous necrosis at incision margin,of which 1 patient (1 knee) was cured by changing dressings,and 1 patient (1 knee) was healed after incision of skin and relaxation suture. The range-of-motion of 51 knees all exceeded 90?. The motion of knee joint were increased from 65?(32?-95?) in average preoperatively to 96?(90?-110?) after the operation. The preoperative pain of all patients disappeared instantly after operation,beside one case (2 knees) and the other had a little pain. The Harris knee joint scores were increased from 39 points (25-53 points) in average preoperatively to 91 points (82-97 points) after the operation at the final follow-up; 25 cases (34 knees) were excellent,12 cases (15 knees) were good,2 cases (2 knees) were fair and the excellent and good rate was 96%. Although TKA has a satisfactory surgical effect,associated factors should be paid more attention.

To observe the preventive effects of flumeprednisolone and spongia gelatinosa on peridural adhesion after nucleus pulposus resection of lumbar intervertebral disc, 153 cases with lumbar intervertebral disc protrusion were selected from the Department of Orthopaedics, Fourth Affiliated Hospital of Guangxi Medical University between June 2002 and August 2006. Among them, the flumeprednisolone and spongia gelatinosa were put surrounding nerve root and dura mater of spinal cord in 83 cases. According to the Macnab criterion, the Lasegue symptom was effectively relieved after operation, and 96.4% of excellent and good result was achieved by periodic follow-up with good functional recovery and satisfactory surgical effect. It indicates that flumeprednisolone and spongia gelatinosa composite is effective in preventing peridural adhesion after intervertebral disc operation.

Objective In order to probe other possible mechanisms of aerobic tra ining in anti-atherosclerosis besides lipid-regulation, we observed the influenc e of aerobic training on the formation of atherosclerotic plaque, the concentrat ion of nitric oxide(NO) in serum, the content of inducible nitric oxidase (iN OS) and endothelial nitric oxidase (eNOS) in thoracic aorta in ApoE-deficient mi ce. Methods The atherosclerotic lesions, the serum NO, the con tent of thoracic aortic iNOS and eNOS by ABC immunohistochemical staining combin ed with computer image quantitative analysis technique on frozen sections were m easured after 10-week swimming training. Thoracic aorta Oil Red O (ORO) staining on the intima were als o analyzed. Results Compared with controls, aerobic training d elayed the plaque formation i n ApoE-deficient mice (P

Objective To investigate the efficacy of steroid spray nose treated in child with chronic nasosi- nusitis.Methods 161 cases who were examined a patient of the 5～14 years old child of a chronicⅠtype nasosi- nusitis were divided into two groups,A group 92 cases,spray with the steroid spray nose+the complex treatment.B group 69 cases,only uses the complex treatment,a month of the course of treatment,two groups of all match with the nasal sinuses to douche.Results All cases were followed-up for at least 6 months.In A group,71 cases were cured,13 cases turned for the better,8 was invalid.Total efficient rate was 91.3 %.In 13 group,40 cases were cured, 13 cases turned for the better,16 was invalid.The efficient rate was 76.8 %.The A group obviously surpassed the B group(P

AimTo study the effect of extracts of ginkgo biloba leaves(GbE) on apoptosis in neuronal cells. Methods Primary cerebral cultures from rat fetus were used to observe the activity of neuronal cells and to determine the release of LDH and DNA gel electrophoresis. Results Gb E enhanced the activity of neuronal cells, decresed the release of LDH,and relieved the structural changes of nucleus and DNA fragmentation. Conclusion GbE can inhibit apoptosis in neuronal cells.

Objective To investigate the effects of intrathecal transplantation of bone marrow stromal cells (BMSCs) on inter cellular cell adhesion molecule-1 (ICAM-1) expression and blood spinal cord barrier following spinal cord ischemia reperfusion injury.Methods Ninety Sprague Dawley rats were randomly divided into three groups:sham (Sham group),ischemia-reperfusion injury (I/ R group),and BMSCs transplantation (BMSCs group).Spinal I/R injury was induced by clamping the aortic arch between left common carotid artery and left subclavian artery for 14 min in I/R group and BMSCs group.Sham group was subjected to exposure of aortic arch but without occlusion.I/R group and BMSCs group were intrathecally injected with phosphate buffered saline (PBS) or BMSCs (2 × 106) two days before injury.At 1 d,3 d,and 7 d after injury,neurological function was evaluated and damaged lumbosacral seg ment was removed for measurement of blood spinal cord barrier permeability and ICAM-1 protein expression.Results Compared with Sham group,neurological function score was significantly lower:1 d (F =38:59,P =0.001),3 d (F =31.34,P =0.001),and 7 d (F =27.71,P =0.001) ; ICAM-1 expression was increased 1 d (F =34.33,P =0.001),3 d (F =29.76,P =0.001),and 7 d (F =23.65,P =0.001),and blood spinal cord barrier permeability was higher:1 d (F =42.57,P =0.001),3 d (F =32.75,P =0.001),and 7 d (F =26.89,P =0.001) in I/R group.Compared with I/R group,neurological function score was increased:1 d (F =16.62,P =0.001),3 d (F =21.54,P =0.001),and 7 d (F =12.84,P =0.002) ; ICAM-1 expression was decreased:1 d (F =19.84,P =0.018),3 d (F =17.38,P =0.008),and 7 d (F =22.46,P =0.007),and blood spinal cord barrier permeability was lower:1 d (F =22.38,P =0.016),3 d (F =27.59,P =0.009),and 7 d (F =23.25,P =0.001) in BMSCs group.Conclusions Intrathecal transplantation of BMSCs inhibited ICAM-1 expression and decreased blood spinal cord barrier permeability,and then attenuated spinal cord ischemia-reperfusion injury.

OBJECTIVE:To study the effects of rosiglitazone(RH)on body weight,FPG,FFA and other indicators in diabe-tes model rabbit. METHODS:18 rabbits were evenly randomized into control group,model group and dextran group. The latter 2 groups were given alloxan intravenously to induce diabetes model. 3 groups were given RH(0.5 mg/kg)intragastrically,and dex-tran group was additionally given dextran 40 glucose injection(5 ml/kg)intravenously,once a day,for consecutive 3 weeks. Body weight,serum level of FPG,FFA,AngⅡ and NO were determined before and after medication. RESULTS:Compared with be-fore medication,body weight of rabbits in control group were increased after medication,while the levels of FFA and AngⅡ were decreased;the levels of FPG and FFA were decreased in model group;body weight of rabbits were decreased in dextran group af-ter medication,with statistical significance (P<0.01 or P<0.05);other indicators had no statistically significant difference (P>0.05). The level of FFA in dextran group was higher than in model group after medication,with statistical significance(P<0.01). CONCLUSIONS:Rosiglitazone can lead to weight gain by a mechanism which reduce the level of FFA.
