[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[Comparative study on two total intravenous anesthesia techniques in complex spine surgery].
To compare anesthesia profiles of target-controlled infusion (TCI) and manual-controlled infusion (MCI) of propofol and remifentanil in kyphosis correction or scoliosis correction surgery, in which intraoperative spinal cord monitoring was employed. ⋯ Both TCI and MCI can offer practical anesthesia for spinal deformity correction surgery. TCI has the advantage in keeping smooth and steady depth of anesthesia.

Comparative Study[Comparison study of endobronchial ultrasound-guided transbronchial needle aspiration and transbronchial needle aspiration for the diagnosis of hilar and mediastinal lesions].
To compare the values of endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) and TBNA for the diagnosis of hilar and mediastinal lesions. ⋯ EBUS-TBNA has a higher diagnostic yield for the evaluation of hilar and mediastinal lesions.

[Analysis of the difference in free influenza vaccination rates between old people in urban and rural areas in Beijing].
To assess the status of free influenza vaccination rates for the elderly in Beijing. ⋯ The vaccination rate among the elderly in Beijing has been raised after the implementation of free influenza vaccination policy in 2007, especially for the rural people. In the urban areas, concerning about the safety of the vaccine is one of the reasons why people chose not to take free influenza vaccination; while in the rural, the insufficient knowledge about the flu and influenza vaccine plays an important role.
