Career Planning and Management of Healthcare Talent Based on Life Cycle Theory

This study aims to explore career planning and management strategies for healthcare talent based on life cycle theory,in order to enhance retention rates and job satisfaction among healthcare professionals.Through qualitative research methods combined with a case study of Liannan County Hospital,the study analyzes the needs and challenges faced by healthcare talent at different career stages.The findings reveal major issues confronted by healthcare talent during career planning,including compensation and benefits,career development opportunities,work environment,and organizational support.The study proposes a series of targeted management strategies,such as individualized career development paths,continuous professional training,and support for work-life balance,to promote long-term retention and career growth of healthcare talent.The conclusion emphasizes that healthcare organizations should consider the life cycle needs of healthcare talent in career planning and management to achieve optimal talent allocation and sustainable hospital development.

CARIDIAC TRANSPLANTATION IN PATIENTS OVER 60 YEARS OLD

Objective To reevaluate the age limit for heart transplantation ( HTX) and the long-term outcomes in el derly patients. Methods From Oct. 1984 to Dec. 1996, 161 cases of HTX were performed in Hartford Hospital, with 35 pa tients aged 60～68 years (mean: 63.5±2.7, group A) and 126 under 60 years (mean: 47.6±11.3, group B). The causes of HTX for group A and group B were ischemic : 60% vs 48%, idiopathic: 29% vs 45%, valvular: 6% vs 4 %, congenital: 0 vs 2%, and graft failure : 6 % vs1% . Results The operative mortality (within 30d) were5.7%(2/35) in group A , and1. 6% (2/126) in group B. The overall late death were 13 (37%) in group A, and 50(40% ) in group B. The main causes of dea th were ( group A vs group B) infection: 46 % vs 24 %, rejection: 0 vs 28 % (P<0.05), malignancy: 23 % vs 8 %, multi-or gan system failure:23% vs 2%, cardiac events:8% vs 10%. The 1-,3-,5- ,8- and 10- year survival rate in group A and group B was 74% vs 88%, 67% vs 77%, 60% vs 65%, 49% vs 43%, and 49% vs 34% respectively. The quality of life for both groups was improved remarkably. Conclusion The survival rate for patients over 60 is as good as that of the younger group. HTX could be successfully performed in patients around 65 years old.

Cage slip characteristics of a cylindrical roller bearing with a trilobe-raceway

Based on dynamic analysis of rolling bearings, the nonlinear dynamic differential equations of a cylindrical roller bearing with a trilobe-raceway were established and solved by the GSTIFF（gear stiff） integer algorithm with a variable step. The influences of structural parameters and the tolerance of the trilobe-raceway, working conditions of the bearing, and the outer ring installation method on cage slip characteristics were investigated. The results show that：（i） The cage slip ratio and bearing rating life of a cylindrical roller bearing with a trilobe-raceway would reduce when the low-radius（radius of the outer raceway contour at the lowest point） and D-value（difference value between the high and low points of the outer raceway contour） decrease, and the former（low-radius） contributes more significantly.（ii） The cage slip ratio of a cylindrical roller bearing with a trilobe-raceway rises with the increase of the bearing speed, and decreases with the increase of the radial force; the variation range increases with the increase of the low-radius.（iii） When the installation angle of the outer ring increases in a period, the cage slip ratio remains unchanged while the bearing rating life rises up a little. Therefore, when installing a cylindrical roller bearing with a trilobe-raceway, the location of the maximum radius shall be under that of the radial force to improve the bearing rating life.（iv） With the increase of the roundness of the base circle where the radius of the lowest points of the trilobe-raceway contour locates, the cage slip ratio rises gradually and the bearing rating life decreases.
