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.

Flavonoid naringin is widely distributed in various types of plants and is an important component of herbal Drynaria. In previous studies, Drynaria has been demonstrated to have inhibitory effects on inflammatory responses and bone destruction and exert anabolic effects on bone, has been widely used in the clinical treatment. Naringin, was in the stage of experimental yet. The experimental results have confirmed that naringin suppressed inflammation including arthritis by lowering the expression of inflammatory cytokines, and the mechanism can be explained as reducing the expression of NF-κB. Naringin has been shown to increase osteoblast proliferation by increasing the expression of BMP-2, inhibit osteoclast activity by reducing the expression of RANKL. In animal experimental, naringin was useful for osteoporosis, and the mechanisms are in-depth studies. Research in the field of traditional Chinese medicine and orthopedics, naringin as a explicit material structure in the components of Drynaria, has been concerned about the experimental studies, it is not only prosperity the development of traditional Chinese medicine research,but also ready for clinical studies anti-inflammatory and bone effects of naringin in the future.
