This article examines and compares the performance evaluation indicator systems of British and American military hospitals,including their hospital system architecture,indicator frameworks,specific indicators,and evaluation methods.To enhance the comparability of indicators,they were categorized into military attributes,service quality efficiency,economic indicators,and growth and development indicators.Based on the comparative analysis of British and American military hospital performance indicator systems,the following suggestions are proposed for the performance evaluation system of public hospitals in China:(1)increasing the indicator diversity and improving the structure of indicators;(2)optimizing indicator reliability throughout the entire process to enhance the scientific ground of the indicator system;and(3)integrating data assets to facilitate joint application of big data.

[Objective]To deepen the theoretical grasp of"the concept of circular transformation"and apply it to unpack the complex pathogenesis of coronary heart disease(CHD),offering a holistic,unified,and adaptable diagnostic and management framework.[Methods]Through historical review and medical principle analysis,it elucidates"the concept of circular transformation"basics and nuances.Merging this with modern research,it discerns CHD's tangled progression,also refers classic formulas,common drugs and diverse clinical practice to pinpoint effective therapeutic approaches.[Results]"The concept of circular transformation"posits that all phenomena are in cyclic and dynamic flux,with human life exhibiting three cycles:Yin-Yang dynamics,the five elements and Qi movement.This framework can explain CHD pathogeneses as:Yin-Yang imbalance from Yang's failure to disperse and Yin evil obstruction;five elements disharmony due to heart and spleen malnourishment and kidney water overflowing into the heart;and Qi circulation disruption from chaotic ascending-descending and misdirected entry-exit.The treatment strategies include warming Yang Qi,dissipating pathogens,harmonizing Yin-Yang;invigorating the spleen and protecting,the heart warming the kidney,supporting Yang and promoting element interaction;and balancing Qi's movements.This work aims to refine"the concept of circular transformation"and offer systematic,dynamic traditional Chinese medicine(TCM)approaches for CHD diagnosis and treatment.[Conclusion]"The concept of circular transformation"blends concepts of perpetual cycles and evolutionary shifts with traditional Chinese medicine's views on Yin-Yang balance,the five elements'interplay and the movements of Qi.This perspective facilitates sophisticated analysis of CHD's complexity,guiding medication choices and dynamic treatment applications in clinical settings.

Objective To explore the effectiveness of virtual autopsy-based postmortem computed tomography(PMCT)liver three dimensional slicer(3D slicer)artificial intelligence(AI)volume reconstruction to assist forensic practice.Methods Twenty cases of the deceased who underwent both virtual autopsy and traditional autopsy in our center were selected and subjected to liver volume segmentation by 3D slicer method,Tada's formula method and literature method,and the data obtained from the traditional autopsy were compared and analyzed to obtain the accuracy rate.Results The 3D slicer method yielded higher consistency(95%confidence interval),lower volumetric variability(standard deviation),and a smaller region(variance)of uncertainty than the Tada formula method and the methods mentioned in the literature.Conclusion 3D slicer AI reconstruction based on virtual autopsy can visualize virtual anatomy,help increase the diagnostic accuracy of traditional autopsy,assist in pathological diagnosis,and provide new directions and tools for the development of imaging histology of virtual autopsy.

Objective To investigate the chemical constituents of marine sponge A gelas mauritiana collected from the South China Sea .Methods The n-butanol extract of marine sponge A gelas mauritiana was separated and purified by repeated column chromatography on silica gel ,Sephadex LH-20 ,and reversed-phase high-performance liquid chromatography (RP-HPLC) .The chemical structures of those obtained compounds were determined on the basis of spectroscopic analysis and com-parison with reported data .The tumor cell growth inhibitory activity of these compounds towards human lung carcinoma cells A549 was tested .Results Eight compounds were isolated ,including agelasine A (1) ,agelasine B (2) ,epi-agelasine C (3) , (-)agelasine D (4) ,agelasine E (5) ,agelasine F (6) ,(-)ageloxime D (7) and aurantiamide acetate (8) .These compounds dis-played different level of tumor cell growth inhibitory activity towards cell A 549 in vitro .Compounds 1-3 showed significant ac-tivity towards cell A549 ,being similar to that of the positive control of adriamycin .Conclusion Compounds 1 ,2 ,4 ,5 ,6 ,8 were isolated for the first time from the sponge A gelas mauritiana .Cell A549 was selected for the first time for the activity evalua-tion of compounds 1~7 .Significant inhibition activity of compounds 2、3 may hold as a basis for further research .
