Objective:To explore the implementation path of scientific and technological achievement empowerment for researchers in public hospitals.Methods:Through literature research, theoretical research, policy research, etc, current situation and progress of the ownership management reform of scientific and technological achievements at home and abroad were sorted out, and the difficult problems in the empowerment of scientific and technological achievements were summarized in combination with its practice in domestic public hospitals.Results:The following problems existed in the empowerment of scientific and technological achievements in public hospitals: weak awareness of medical staff′s ownership protection imperfect empowerment system, lagging construction of management personnel, and constraints of state-owned assets management.Conclusions:It is suggested to improve the coordination mechanism of government departments, optimize related policy and law environment and innovation atmosphere, implement a categorized and tiered empowerment strategy for job scientific and technological achievements, set up a management platform of medical scientific and technological achievements, build a complete support service system, establish a mechanism for cultivating and producing high-value achievements, and strengthen the construction of achievement management personnel.

BACKGROUND/OBJECTIVES@#Benign prostatic hyperplasia (BPH) is the most common prostate disease and one of the most common chronic diseases caused by aging in men. On the other hand, there has been no research on BPH using Abeliophyllum distichum Nakai (A.distichum). Therefore, this study investigated the effects of A. distichum on BPH.MATERIALS/METHODS: A. distichum leaves were extracted with distilled water, 70% ethanol, and 95% hexane as solvents. Subsequently, the inhibitory effects of each A. distichum extract on androgen receptor (AR) signaling were evaluated in vitro. The testosterone-induced BPH model was then used to confirm the efficacy of A. distichum leaves in 70% ethanol extract (ADLE). @*RESULTS@#ADLE had the strongest inhibitory effect on AR signaling. A comparison of the activity of ADLE by harvest time showed that the leaves of A. distichum harvested in autumn had a superior inhibitory effect on AR signaling to those harvested at other times. In the BPH rat model, the administration of ADLE reduced the prostate size and prostate epithelial cell thickness significantly and inhibited AR signaling. Subsequently, the administration of ADLE also reduced the expression of growth factors, thereby inactivating the PI3K/AKT pathway. @*CONCLUSIONS@#An analysis of the efficacy of ADLE to relieve BPH showed that the ethanol extract grown in autumn exhibited the highest inhibitory ability of the androgen-signaling related factors in vitro. ADLE also inhibited the expression of growth factors by inhibiting the expression of the androgen-signaling related factors in vivo. Overall, ADLE is proposed as a functional food that is effective in preventing BPH.
