[Treatment of the old terrible triad of the elbow without operative history].
To introduce the surgical techniques and treating results of the old "terrible triad" of the elbow. ⋯ The old "terrible triad" of elbow with no operative history is difficult to treat. The elbow's functions and stabilization can be recovered by thorough elbow release, repair of coronoid process and anterior capsule, radial head fractures, lateral collateral ligament and the common extensor tendon insertion, combined with hinged external fixator. Joint stiffness and heterotopic ossification are common complications.

[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.
