[Influence of inhaled anesthesia on bispectral index of elderly patients with cognitive decline].
To investigate the influence of inhaled anesthesia on bispectral index (BIS) of elderly patients with cognitive decline at loss of consciousness and regain of consciousness, and on deepening of sedation. ⋯ During inhaled anesthesia, the BIS of the elderly patients with cognitive decline at loss of consciousness is higher than that of the patients with cognitive intact, The BIS of elderly patients with cognitive decline on deepening of anesthesia is lower than that of the patients with cognitive intact, especially during light anesthesia, and its mechanisms may attribute to cognitive decline related neurodegeneration and neurotransmitter system dysfunction.

[Genome-wide copy number scan in Chinese patients with premature ovarian failure].
To investigate genetic causes in Chinese women with primary ovarian insufficiency (POI) for Genome-wide copy number variations (CNVs), focusing on novel autosomal microdeletions and microduplications. ⋯ We report the high-resolution rare CNV analysis, revealing novel microdeletions/microduplications in Chinese POI patients. In the selected verified coding regions, we find that the five genes including SYCE1, CYP2E1, NRXN1, PARK2 and CARD11 may be involved in reproduction, thus representing potential candidate genes in POI.

[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.

[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.

Randomized Controlled Trial Comparative Study[Minimal invasive internal fixation with U-shaped break-off pedicle screws for treatent of thoracolumbar fractures].
To investigate the clinical outcome of minimal invasive internal fixation with U-shaped break-off pedicle screws through paraspinal muscle sparing approach to treat thoracolumbar fractures, and to discuss its advantages. ⋯ Through paraspinal muscle sparing approach minimal invasive internal fixtation with U-shaped break-off pedicle screws to treat thoracolumber has more advantages than traditional procedure in blood control and quick recovery. The method needs no special instruments and don't increase X-ray exposure.
