OBJECTIVETo investigate the feasibility and effectivity of using compound material of fibrin glue and DBM as scaffolds for cartilage tissue engineering.

METHODSChondrocytes isolated from articular cartilage were seeded into prepared scaffolds, after incubation for 4 weeks in vitro. Chondrocytes and fibrin glue and DBM constructs were implanted in the joint cave of rabbit. The specimens were excised at the 4th, 8th, 12th week, examined grossly analyzed by haematoxylin cosine, toluidine blues staining and type II collagen immunohistochemistry reaction. Wakitani score was counted to evaluate the repairing effect.

RESULTSGrossly analysis showed some ivory tissue filled the caves after 4 weeks and the caves were full filled with smooth surface after 12 weeks. The microscope showed a good deal of chondrocytes appeared after 8 weeks and more type II collagen than 4 weeks. Twelve weeks later, cartilage lacuna could be observed. The cells arrangement and the amount of type II collagen both showed the same as the natural one.

CONCLUSIONComplicated material of fibrin glue and DBM as scaffolds can be used as scaffolds for cartilage tissue engineering.

OBJECTIVETo compare the radiographic and functional outcomes of nonoperative and minimally invasive methods in treating femoral subtrochanteric fractures in children.

METHODSForty-five children (male 28, female 17) aging from 4- to 15-years-old with femoral subtrochanteric fracture were managed with traction and cast application (16 cases), and elastic intramedullary nailing (29 cases). Early and late radiologic outcomes were respectively evaluated by Beaty and Theologis criteria. The outcomes of clinical effect were evaluated with Sanders scoring system.

RESULTSAll patients were followed up from 26 to 62 months with an average of 39.5 months. The fractures united in 45 patients. Early (at 4th week after treatment) satisfactory radiologic outcomes were respectively 6 cases and 26 cases between two methods of nonoperative and minimally invasive. Late (at 2nd year after treatment) satisfactory radiologic outcomes were respectively 11 cases and 28 cases between two methods of nonoperative and minimally invasive. According to Sanders scoring, 12 cases were excellent, 4 good with nonoperative methods; and 28 excellent, 1 good with minimally invasive methods. There were significant differences between the two groups in aforesaid aspect.

CONCLUSIONMinimally invasive methods provided more satisfactory alignment of fractures as well as better functional outcomes than nonoperative methods. It is the first choice to treat femoral subtrochanteric fractures in children.

OBJECTIVETo study the role of PCR technique in detection of mycobacterium tuberculosis in the samples from joint tuberculosis, and to evaluate the clinical value of PCR in diagnosis of joint tuberculosis.

METHODSFrom June 1993 to August 2001, PCR was used to detect DNA of mycobacterium tuberculosis, and the standard culture was applied to detect mycobacterium tuberculosis. Mycobacterium tuberculosis were respectively blindly by the two techniques in the samples obtained from 95 patients with joint tuberculosis (55 males and 40 females, the age ranging from 2 to 75 years, with an average of 34 years). The positive rate of mycobacterium tuberculosis detection was calculated.

RESULTSIn the detection of mycobacterium tuberculosis, positive rate was 82% (78/95) in PCR technique, and 16% (15/95) in standard culture technique. There were statistical differences between the two groups (chi2=67, P<0.001). The whole process of PCR amplification was automatic and could be finished within several hours, and the detecting time was considerably shorter.

CONCLUSIONPCR technique is a rapid, simple, sensitive and specific method for detection of mycobacterium tuberculosis in the samples of joint tuberculosis, showing more marked advantages than the standard culture technique. It is valuable in the early rapid diagnosis and differential diagnosis of joint tuberculosis.
