[Efficacy analysis of two-stage reverse total shoulder arthroplasty for treating postoperative deep infection after surgeries for proximal humeral fractures].
To evaluate the clinical results of two-stage reverse total shoulder arthroplasty for treating postoperative deep infection after surgeries for proximal humeral fractures. ⋯ two-stage reverse total shoulder arthroplasty was an effective treatment for the postoperative deep infection after surgeries for proximal humeral fractures. The shoulder function was postoperatively improved to a certain degree.

[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.

[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.

[Ultrasound-assisted neuraxial anesthesia in a patient with previous lumbar laminectomy and fusion: a case report].
A patient with previous L3-4 posterior lumbar interbody fusion, pedicle screws instrumentation and L3-4 decompression, was scheduled for left total hip arthroplasty. Two years ago, due to poor landmarks palpation, the patient experienced a failed lumbar puncture after multiple attempts before herniorrhaphy. His plain radiography showed bilateral partial laminectomy at L3-4 level, and between L3 and L4, two posterior pedicle screws connected by metal rods on both sides. ⋯ The surgery was uneventful. No neurologic complication was observed after the surgery. This case report demonstrates that ultRASound imaging can provide useful information for neuraxial needle placement and can be a valuable tool in managing patients with anatomical change around the spine.
