Objective:
To construct a competency evaluation model for health managers based on the grounded theory, so as to provide insights into the training and evaluation of health managers.
Methods:
From December 2022 to March 2023, health managers with three years and more of working from health management center of a tertiary hospital, a health management enterprise and a university with a top-tier ranking for the major of "Health Services and Management" were invited, and a semi-structured interview on competency was conducted based on grounded theory. Coding techniques were applied to analyze the interview data, including open coding, axial coding, selective coding and theoretical saturation testing using NVivo12 software. Based on the coding results and drawing inspiration from McClelland's "Iceberg Competency Model Structure", a competency evaluation model for health managers was formulated.
Results:
Twenty-one health managers participated in the study, including 8 participants from the hospital, 7 participants from the enterprise and 6 participants from the university, 14 females, 17 participants with 3-10 years of working, and 6 participants with the rank of associate senior professional title or above. The interview yielded 5 main categories, from which the competency evaluation model for health managers was developed with five dimensions: professional development, health management capability, communication and coordination, humanistic care, and personal traits. professional development and health management capability constituted the overt competencies of health managers, while communication and coordination, humanistic care, and personal traits formed their implicit competencies.
Conclusions
The competency evaluation model for health managers constructed in this study includes explicit competency and implicit competency, which is expected to serve as a reference for the effective selection and cultivation of health managers.

Objective To investigate the roles of somatostatin(SS)positive intemeurons in the development and compensation of temporal lobe epilepsy.Methods Piloearpine-induced epilepsy rat model was established.Immunohistochemistry method was used to detect number changes and axonal sprouting of SS positive intemeurons in different domains of the hippocampus at difierent time points.Degeneration of SS positive interneurons and their neurophils were detected by the double immunofluorescence staining with SS and Fluoro-Jade B(FJB)at 7 and 60 days after status epilepticus (SE).Results In the exoerimental rat group,the number of SS positive neurons decreased in each hippocampal domain,and it reached the lowest at 7 days post-SE(There were 11.1±3.3 in hilus,2.8±0.9 in CA1region and 1.8±0.7 in CA1region,t=13.519,9.644 and 8.808,all P<0.01).In chronic phase,the number of SS neurons gradually recovered,and exceeded the control group in CA1 area at 60 days post-SE(12.8±1.5 vs 8.8±1.3,t=-4.506,P<0.01),however,the number of SS neurons in the hilus(25.5±4.6)and CA1 area(4.8±0.8)remained significantly less than normal levels(t value were 4.691 and 3.953.both P<0.01).Increased SS positive fibers were found in the lacunosum-molecular (1m)layer and outer molecular layer of dentate gyrus after 30 days post-SE,and numerous SS positive fibers were seen threnghout the layers of area CA1 at 60 days post-SE.Double immunofluuorescence revealed that a few SS positive interneurons and fibers were also labeled by FJB in area CA1 at 7 days post-SE and in CA domain/hilus at 60 days post-SE.Conclusions SS intemeurons loss plays an important role in the development of temporal lobe epilepsy.The loss is partially caIlsed by the degeneration and death of neurons;SS positive neurophils increase within area CA1 in chronic phase may play a significant role in the generation and compensation of temporal lobe epilepsy.

The oil content and fatty acid composition of Ganoderma lucidum collected from different producing areas, varieties, tissue types and growth periods were measured and analyzed. The results showed that the oil content was 23. 61%-34.17% in different domestic producing areas of China; the oil content of fruiting bodies from major varieties cultured in Zhejiang province were 0.81%-1.87%, wall-unbroken spores were 0.07%-0.24%, wall-broken spores were 27.54%-34.17%, so the oil content of wall-unbroken spores were much higher than fruiting bodies, and wall-breaking treatment would increase the oil extraction rate 150-340 times. G. lucidum spores oil was mainly composed of unsaturated fatty acid composition. oleic acid and linoleic content were 53.26%-58.16% and 10.69%-16.87% respectively. Fatty acid composition ratio of spores and fruiting bodies were significantly different by PLS-DA. Determining the composition of fatty acid, especially the content of oleic acid, stearic acid and palmitic acid, could identify the tissue types of G. lucidum products' sources. In addition, the study result showed that the spores and fruiting bodies collected in the first year contained richer oil and fatty acid than second year's samples from the same variety of G. lucidum.
