Background Hypertension is a silent disease of the masses with an increasing prevalence and poor control rates. This study aims to establish and test the efficacy of a nurse-led hypertension management model in the community. Methods A single-blind, randomized controlled trial was performed. 156 hypertensive patients with uncontrolled blood pressure were equally and randomly allocated into 2 groups. Patients in the study group received a 12-week period of hypertension management. Blood pressure, self-care behaviors, self-efficacy, and satisfaction were assessed at the start of recruitment, 12 and 16 weeks thereafter. Results After the intervention, blood pressure of patients in the study group had greater improvement in self-care behaviors and a higher level of satisfaction with the hypertensive care compared to the control group (both P Conclusions The nurse-led hypertension management model is feasible and effective for patients with uncontrolled blood pressure in the community.

To explore the new method for the design of humanoid robot driving system. This driving system is to use the force-line model to parallel drive the limbs of the robot. A humanoid robot driving system with the force-line model has been constructed. New software for muscle force estimation has been developed. The solution of the parameters which are the input of the software has been statement. Finally, the input parameters have been obtained by experiment and calculation. The humanoid robot can be parallel driven to imitate human walking by the force which along the force-line. It will provide wide insight in developing new type humanoid robot for complex motion.

Applying EHL theory, the paper derives the mathematical model for analysis of lubricating a cylinder sleeve and piston ring. It also composes a general CAD program for computation of the thickness of the lubricant film, by which analysis can be made for the lubricating state of the cylinder sleeve and piston ring for engines of various models with different operating modes. Tests of a specific point on the bench at specific conditions show that the computing method is feasible.
