[Separate vertical wiring combined with tension band and Kirschner-wire plus cerclage wire in the treatment of displaced inferior pole fractures of the patella].
To investigate the clinical efficacy and outcomes of two separate vertical wiring combined with tension band and Kirschner-wire plus cerclage wire in the treatment of displaced inferior pole fractures of the patella. ⋯ Two separate vertical wiring is an easy and effective method to reduce the displaced inferior pole fracture of patella. Augmentation of separate vertical wiring with tension band and Kirschner-wire plus cerclage wire in these patients provides enough strength to protected the early exercise of the knee joint and uneventful healing. By this surgical treatment, excellent results in knee function can be expected for cases of displaced inferior pole fractures of the patella.

[Evaluation of physical function for the end-stage osteoarthritis patient waiting for the total knee replacement].
To collect comprehensive data of the physical function of the end-stage osteoarthritis (OA) patients, and compare it with patients with mild OA. To evaluate the correlations among pain, self-reported questionnaire, performance based physical function and actual daily life activity level. ⋯ The usage of lots of different physical parameters from Chinese OA patients were reported in this study. The results showed that there are no good correlations among performance based physical function test, actual daily activity level, self reported questionnaires, and the pain scales. More comprehensive evaluation for the OA patients needs to be made, in order to make better decision for arthroplasty.

[Evaluation and analysis of the tibial coronal alignment after total knee replacement with the extramedullary tibial cutting guided by the tibial tubercle and anterior tibial tendon in Chinese patients].
To evaluate the efficiency of the tibial coronal alignment after total knee arthroplasty with the extramedullary cutting system guided by the tibial tubercle and anterior tibial tendon, and to discuss the potential risk factors for the postoperative malalignment. ⋯ The tibial coronal alignment after total knee arthroplasty could achieve good results with extramedullary cutting guide, by using one third inner-medial tibial tubercle and anterior tibial tendon as a proximal and distal anatomy marker. Postoperative varus might occur in this system, and tibial prosthetic malalignment appeared more often in the patients who suffered a severe deformity before surgery.

[Influence of sevoflurane concentration and stimulation voltage on motor evoked potentials in intraspinal tumor surgery].
To evaluate the effects of increasing end-tidal concentrations of sevoflurane and increasing stimulation voltage on motor evoked potentials, so as to provide evidence in making anesthesia plan for intraspinal tumor surgery. ⋯ Sevoflurane inhibited MEPs in a dose-dependent manner. It can decrease the amplitudes and prolong the latencies. But increasing stimulation voltage will facilitate MEPs monitoring and increase the success ratio. Sevoflurane can be used in larger parts of MEPs monitoring surgery by increasing the stimulation voltage.

[Hydrogen sulfide in cartilage and its inhibitory effect on matrix metalloproteinase 13 expression in chondrocytes induced by interlukin-1β].
To investigate whether endogenous hydrogen sulfide (H2S) was involved in the pathogenesis of osteoarthritis (OA) and its underlying mechanism, to detect H2S and its synthases expression in knee cartilage in patients diagnosed with different severity of OA, and to explore the transcription and expression of gene MMP-13 in chondrocytes treated with IL-1β or H2S. ⋯ H2S affected the cartilage degeneration by partly inhibiting the degradation of extracellular matrix.
