[Analysis of sagittal parameters about senior thoracolumbar proximal junctional kyphosis after lumbar long segment fusion].
To explore the radiographic risk factors of senior thoracolumbar proximal junctional kyphosis (PJK) after lumbar long segment fusion. ⋯ PJK after lumbar long segment fixation of elderly patients can aggravate the sagittal imbalance and reduce functional scores. The operator should pay great attention to restoring the lumbo-pelvic lordosis.

[Quantitative ultrasound scans of the calcaneus: a useful tool for screening osteoporosis in patients with connective tissue disease].
To evaluate the ability of calcaneus quantitative ultrasound (QUS) to diagnose osteoporosis in connective tissue disease (CTD) patients. ⋯ Our study confirmed that QUS measurements performed at calcaneus with quantitative ultrasound bone analysis were capable of screening osteoporosis defined by axial BMD using DXA in female CTD patients.

[Anesthesia management of laparoscopic radical cystectomy and orthotopic bladder surgery with a robotic-assisted surgical system].
To summarize anesthesia management of laparoscopic radical cystectomy and orthotopic bladder surgery with a robotic surgical system. ⋯ Robot-assisted radical cystectomy + orthotopic bladder surgery is a newly-performed clinical surgery. Because of the huge machines, long time pneumoperitoneum and over-head-down, it is prone to acid-base balance and ion imbalance, thus increasing the difficulty and complexity to anesthesia management. It's necessary to further summarize the impact on the respiratory, hemodynamic, and nervous system.

[Finite element analysis of lumbar fusion and Topping-off surgery].
To evaluate the effect of Topping-off surgery on the adjacent segment of PLIF. ⋯ Topping-off model is able to restrict the range of motion of the lumbar adjacent segment, decrease the intradiscal pressure and facet stresses, and has a potential effect of preventing adjacent segmental degeneration.

[Effect of cement implantation and pressor agents in hip replacement on blood pressure].
To discuss the change of blood pressure involved by pressor agents after the implantation of cement in hip replacement. ⋯ Implantation of cement in hip replacement surgery causes blood pressure decreasing. The application of pressor agents before cement implantation can stabilize blood presure and shorten the period of hypotension.
