[Objective]To re-examine ZHU Danxi's"Theory of Ministerial Fire"under the influence of the Neo-Confucian doctrine of"cultivating moral nature and controling emotion wth moral consciousness",tracing its philosophical origins,revealing its philosophical connotations,clarifying its philosophical value,and guiding its medical applications.The aim is to refine the theoretical research on the Theory of Ministerial Fire and enhance its clinical utility.[Methods]Based on ZHU Danxi's medical works such as Gezhi Yulun(Supplemental Treatise on Extending Knowledge Through Scrutiny of Principles)and Jufang Fahui(Elucidation of the Formulas of the Imperial Pharmacy Bureau),supplemented by medical theories from Huangdi Neijing(The Inner Canon),LIU Wansu,and others,as well as Neo-Confucian writings by ZHOU Dunyi,ZHU Xi,and others,this study employs methodologies from traditional Chinese medicine(TCM)and Chinese philosophy,including literature review and comparative analysis.It explores key questions such as the origin of ministerial fire in the human body,what governs it,and how it is regulated.[Results]The philosophical foundation of ZHU Danxi's"Theory of Ministerial Fire"lies in his intellectual lineage from the"Beishan school"and his inheritance of"CHENG-ZHU Neo-Confucianism".Among these influences,ZHU Xi's doctrine of"cultivating moral nature and controling emotion wth moral conscious-ness"had a particularly profound impact on Danxi's theory.This doctrine posits that human consciousness and perception("the mind")can cultivate moral essence("nature")and regulate emotional-desire activities("emotions").The philosophical connotation of Danxi's"Theory of Ministerial Fire"is that"ministerial fire"arises from desire-driven"emotions"but is rooted in moral"nature".The sovereign fire represents the conscious"mind",which governs ministerial fire.Danxi advocates using Neo-Confucian moral cultivation methods such as"tranquility and desirelessness"and"letting the moral mind prevail"to restrain the"reckless movement"of ministerial fire while maintaining its"constant motion".The philosophical value of Danxi's theory lies in its embodiment of the Zhejiang academic tradition of"practical statecraft",its reflection of the Yuan Dynasty's intellectual trend of"harmonizing ZHU Xi and LU Xiangshan's philosophies",and its influence on later medical developments that"invoking Neo-Confucianism to guide medicine".In medical practice,to sustain the"constant motion"of ministerial fire and ensure health,Danxi emphasizes both moral cultivation and the use of herbal formulas,such as Dabuyin Piu(Great Yin Supplementation Pill)to nourish Yin and suppress fire.This approach earned him recognition as the founder of the"Nourishing Yin school".[Conclusion]The"Theory of Ministerial Fire"is a core medical theory of ZHU Danxi shaped by Song-Yuan Neo-Confucianism and a key representative of the"invocation of Neo-Confucianism to guide medicine"during the Jin-Yuan period,remaining relevant to modern medical practice.Rich in philosophical depth,the theory's essence lies in unifying"moral cultivation"and"health preservation",asserting that nurturing virtue is synonymous with preserving life.This not only infuses ZHU Xi's doctrine of"cultivating moral nature and controling emotion wth moral consciousness"with tangible medical significance,guiding clinical practice,but also constructs a metaphysical philosophical framework for Danxi's theory,illuminating its Neo-Confucian brilliance.

[Objective]To explore Professor XU Guangxing's experience in differentiating and treating gastric cancer based on the"Yangming Weihe(stomach closed)"theory.[Methods]Through clinical shadowing,organizing and analyzing medical cases,and studying relevant literature,combined with Professor XU Guangxing's understanding of gastric cancer,this paper summarizes his experience in differentiating and treating gastric cancer based on the"Yangming Weihe"theory from the perspectives of theoretical connotation,etiology,pathogenesis and medication strategies.A medical case is included for validation.[Results]The theory of"Yangming Weihe"originates from the opening-closing-pivot theory.The Yangming closing mechanism serves as a component of the ascending and descending movement of Qi in the human body.Together with the Taiyin opening mechanism and the Jueyin closing mechanism,it collectively regulates the physiological functions of the stomach.Professor XU Guangxing proposes that the etiology and pathogenesis of gastric cancer can be categorized into three patterns:dysfunction of the Yangming closing mechanism;impaired Taiyin-Yangming opening-closing coordination;dual dysfunction of the Jueyin-Yangming closing mechanisms.His therapeutic strategies focus on:clearing heat,moistening dryness and promoting descending with bitter flavors to unblock Yangming;strengthening the spleen and harmonizing the middle-Jiao to support the opening-closing mechanism;dispersing wind pathogens and consolidating dissipation to restore the dual closing mechanisms.The attached medical case involved a postoperative gastric cancer patient,diagnosed as dual Jueyin-Yangming closing mechanism failure according to the"Yangming Weihe"theory.The treatment protocol emphasized:clearing dryness,nourishing Yin and unblocking-tonifying Yangming;dispersing wind,astringing dissipation and consolidating-descending Jueyin.The herbal regimen achieved stable and positive outcomes.[Conclusion]Professor XU Guangxing's approach to treating gastric cancer based on the"Yangming weihe"theory is characterized by unique insights into the etiology and pathogenesis,distinctive features in syndrome differentiation and treatment,and notable clinical efficacy.This methodology merits further research and broader promotion.

Guided by ZHANG Jiebin's "water-fire of life gate theory"， this paper explored the etiology， pathoge-nesis， and syndrome differentiation-based treatment approach for esophageal cancer. It is proposed that the core pathogenesis of esophageal cancer， derived from the imbalanced state of water and fire in life gate， can be summarized into three manifestations. Firstly， decline of life gate fire leads to failure of qi transformation and accumulation of phlegm and blood stasis； secondly， fire fails to warm the earth resulting in dysfunctional ascending and descending， and qi stagnation and blood stasis； thirdly， deficiency of life gate water contributs to proliferation of cancerous toxins and physical deterioration. In terms of treatment， guided by ZHANG's treatment principles for dysphagia， three treatment methods are proposed， warming and tonifying kidney yang to promote qi transformation through steaming action， warming and nourishing the spleen and stomach to restore central pivot movement， and nourishing kidney water to replenish essence and blood， then support bodily nourishment. Clinical case examples are provided to illustrate the application of these methods.

Objective:To explore the value of clinical and biparametric magnetic resonance imaging(bpMRI)in diagnosing extraprostatic ex-tension(EPE)of prostate cancer(PCa).Methods:This retrospective study assigned 107 patients into EPE(n=42)and organ-limited(n=65)groups based on their postoperative pathology after radical prostatectomy from August 2018 to May 2024 at Wuhu Second People's Hospit-al.The differences in the following clinical risk indicators were compared between the groups:age,total prostate specific antigen(tPSA),pro-state volume,prostate specific antigen density(PSAD)and International Society of Urological Pathology(ISUP)score for prostate puncture.The differences in MRI indicators,prostate imaging reporting and data system(PI-RADS)score and bpMRI were also identified.Binary Logist-ic regression analysis was used to construct clinical and joint models for diagnosing EPE,and screening independent influencing factors.The ROC curve analyze the independent influencing factors and diagnostic performance of the models.The DeLong test was used to compare the differences between the AUC models.A nomogram was draw,and performance evaluated.Results:The differences in tPSA,PSAD,ISUP score for prostate puncture,PI-RADS score,and bpMRI were statistically significant between the two groups(P<0.05).The clinical model AUC was 0.821;while the AUCs of the combined model and independent influencing factors PSAD(OR=25.992),ISUP score for prostate puncture(OR=1.676),and bpMRI(OR=10.729)were 0.899,0.813,0.770,and 0.793 respectively(P<0.001).The combined model was superior to the clinical model(Z=2.502 and P=0.012).The average AUC for 5-fold cross-validation was 0.887,with high model calibration and a threshold range of 5%-85%,indicating clinical benefits.Conclusions:The combined model nomogram derived from clinical and bpMRI indicators is highiy valuable for diagnosing PCa EPE.

[Objective]To explore the connotation of neo-Confucianism in ZHU Danxi medicine.[Methods]Combining the research methods of medicine and philosophy,based on ZHU Danxi's medical writings and related knowledge of neo-Confucianism,the connotation of neo-Confucianism of Danxi medicine was discussed from three aspects:"cognition view""sports view""cultivation view".[Results]ZHU Danxi was influenced by the thought of"one principle and different justics"and regarded medicine as the way to practice Confucian ideal.Using the understanding method of"thinking phyics",ZHU Danxi put forward some important medical theories such as"the theory of excess of Yang and deficiency of Yin"and"the theory of fire".Based on the concept of"movement was the heart of heaven and earth",the important significance of Qi movement and constant movement of"Xiang fire"to human life was realized.Based on the sports concept of"extreme things must be reversed"and"the gentleman should be careful to move",the author realized the great harm to the human body caused by the rash movement of"fire"and advocated the idea of"careful movement"for health preservation.Based on the cultivation view of"heart regulating temperament",the author put forward"king fire mastering prime minister fire",emphasized the active role of"heart"of"king fire",cultivated the"nature"of morality,controlled the"emotion"of desire,and maintained the constant movement of"corresponding fire"and supplemented life.Applying the cultivation view of"mastering static without desire"to health but disease required that through tempering appetite and lust,people's natural desires conformed to the Confucian"reason",in order to be no severely ill and spend the whole life.[Conclusion]ZHU Danxi's medical science is rich in connotation,which is a powerful witness of the influence of the reform of Confucianism on medical innovation in Song and Yuan Dynasties.On the one hand,Danxi's"aid theory into medicine"built a strong support for medical innovation,and made his medical theory rise to the height of"heaven theory",so that he was convinced in the Jinyuan period of medical contention;On the other hand,it also demonstrated the all-encompassing universality and supreme authority of"heavenly principles"as cosmic laws.

Femoral neck fracture (FNF) in the elderly patients is currently a major health challenge worldwide, with excessive consumption of medical resources, high incidence of complications as well as suboptimal outcome and prognosis. Hip joint arthroplasty (HJA) has been the mainstream treatment for FNF in the elderly, but the conventional surgical approaches and techniques are still confronted with a series of bottlenecks such as dislocation, limp and limb length discrepancy. In recent years, direct anterior approach (DAA) for HJA (DAA-HJA) has been a major new choice in the field of joint replacement, which achieves improved clinical effectiveness of HJA in the treatment of elderly FNF, due to the fact that DAA approach involves the neuromuscular interface and accords with the idea of soft tissue retention and enhanced recovery after surgery. However, there is still a lack of unified understanding of standard technique and procedure of DAA-HJA in the treatment of elderly FNF. Therefore, relevant experts from the Hip Joint Group of Chinese Orthopedics Association of Chinese Medical Association, Youth Arthrology Group of Orthopedic Committee of PLA, Orthopedic Committee of Chongqing Medical Association, Branch of Orthopedic Surgeons of Chongqing Medical Doctor Association and Sport Medicine Committee of Chongqing Medical Association were organized to formulate the " Chinese expert consensus on the technical standard of direct anterior hip arthroplasty for elderly femoral neck fracture ( version 2023)" based on evidence-based medicine. This consensus mainly proposed 13 recommendations covering indications, surgical plans, prosthesis selections, surgical techniques and processes, and postoperative management of DAA-HJA in elderly patients with FNF, aiming to promote standardized, systematic and patient-specific diagnosis and treatment to improve the functional prognosis of the patients.
