OBJECTIVETo detect the expression of the glucocorticoid receptor-alpha/beta (GR-alpha/beta) mRNA in nasal polyp and normal nasal mucosa and investigate the significance of receptor-alpha/beta in GC-insensitive and GC-sensitive patients.

METHODSThe expression of GR-alpha/beta mRNA in 40 samples of nasal polyp and 30 normal nasal mucosa was examined by using Fluorescent quantitative PCR.

RESULTSForty cases were screened from the 80 cases after follow-up, including 26 cases of GC-sensitive and 14 cases of GC-insensitive. the levels of GR-beta mRNA in group of GC-insensitive [(5.72 +/- 0.58) x 10(2) copy/microg] were significantly higher than that of GC-sensitive [(4.82 +/- 0.28) x 10(2) copy/microg, t = -6.65, P < 0.01] and normal nasal mucosa [(4.44 +/- 0.35) x 10(2) copy/microg, t = -9.19, P < 0.01]. There was difference between group of GC-insensitive and other two groups of GC-sensitive and normal nasal mucosa (P < 0.01). The ratio of GR-alpha/GR-beta showed significant difference between the group of GC-sensitive (829.42 +/- 67.36) and that of GC-insensitive (535.70 +/- 89. 00, t = 11.74, P < 0.01).

CONCLUSIONSThe high expression of GR-beta mRNA and low expression of GR-alpha mRNA in nasal polyp show the status of "insensitive" in chronic sinusitis and nasal polyp. The GR-beta may play an important role in evaluating the effect of glucocorticoid in chronic sinusitis and nasal polyps.

OBJECTIVETo study the influence of separation of distal tibiofibular syndesmosis on ankle joint and to compare various operative methods so as to find suitable stabilization for separated distal tibiofibular syndesmosis.

METHODSFrom July 1997 to July 2002, we treated 87 patients (64 males and 23 females, aged 18-54 years) with separation of distal tibiofibular syndesmosis, among whom, 79 were combined with fracture of malleolus. Manipulative reduction, internal fixation with cancellous screws and external fixation with plaster support were performed on 37 patients, fixation with plate and screws for fibular fracture and fixation with cancellous screws for distal tibiofibular syndesmosis on 34 patients, and repair of the distal tibiofibular ligaments with tendon of peroneus longus, reduction of the separated distal tibiofibular syndesmosis, and fixation with cancellous screws on 16 patients. The ankle joint had been dorsiflexed for 30 degrees when the distal tibiofibular syndesmosis was fixed with cancellous screws. And the cancellous screws were taken out at 8-10 weeks after operation.

RESULTSThese patients were followed up for at least two years. The curative effects were assessed according to the complaints of the patients and the contour, function and radiogram of the ankle joint: excellent in 55 patients (63%), good in 18 patients (21%), and fair in 14 patients (16%). Separation of distal tibiofibular syndesmosis recurred in 2 patients, who underwent a reoperation for repairing the distal tibiofibular ligaments with tendon of peroneus longus and recovered. One cancellous screw was broken off. No necrosis developed in the anterior skin of the ankle mortise.

CONCLUSIONSSeparation of distal tibiofibular syndesmosis can be treated with various reasonable operations. Repair with tendon of the peroneus longus can get excellent outcomes for complete separation of the distal tibiofibular syndesmosis.

OBJECTIVETo explore the value of surgical treatment on spine metastatic tumor.

METHODS31 cases of spine metastatic tumor with severe pain or/and neurological deficit were selected and treated with various operative methods.

RESULTSExcept for 4 cases, all the patients survived from 3 months to 7 years (average 17.6 months). The patients had no complication during treatment. The symptoms and neurological functions recovered with various extent after operation.

CONCLUSIONSSurgical treatment should cautiously be adopted. When the spine metastatic tumor with severe pain and neurological deficit has no response to the conservative methods, the surgical treatment with decompression and internal fixation should be performed to improve the life quality for the patients.

OBJECTIVETo test the changes of the stiffness of the intact, released, and instrumented spines in an in vitro porcine model.

METHODSTwelve porcine spines (12 segments each) were harvested for the biomechanical tests with Material Test System. Stiffness during flexion, extension, lateral bending, and axial rotation were recorded; then the specimen was released with intervertebral discs and the facet joints removed, followed by repeating the biomechanical tests for stiffness; and finally, a double-rod titanium construct was applied for internal fixation to each released spine and stiffness tests were repeated again.

RESULTSCompared with the intact porcine spines [stiffness during flexion, extension, lateral bending, and axial rotation was 52.89 +/- 15.98, 105.43 +/- 56.38, 42.09 +/- 14.73, and (16.94 +/- 4.85) N x mm/degrees, respectively], the stiffness of the released porcine spines [stiffness during flexion, extension, lateral bending, and axial rotation was 44.04 +/- 13.73, 41.46 +/- 10.80, 31.75 +/- 7.23, and (9.10 +/- 2.07)N x mm/degrees, respectively] significantly decreased (P < 0.05), while significantly increased stiffness was found in the instrumented porcine spines [stiffness during flexion, extension, lateral bending, and axial rotation was 385.96 +/- 143.25, 138.96 +/- 59.41, 152.56 +/- 87.15, and (55.91 +/- 16.49) N x mm/degrees, respectively] (P < 0.05).

CONCLUSIONHigher instant stiffness was found in instrumented spine than the intact one during flexion, extension, lateral bending and axial rotation.
