The chronicity of infectious diseases is an important field in the collaborative research of traditional Chinese and Western medicine. The warm disease theory of pathogen invading nutrient and blood aspects in traditional Chinese medicine （TCM） takes the struggle between healthy Qi and pathogenic Qi and cementation of Yin as the core pathogenesis， providing a unique theoretical framework for explaining the common pathology of infectious chronic diseases. This theory originated from Yin-Yang interaction in the Internal Classic and was enriched with WU Youke's theory of intruding pathogen interacting and lingering in blood vessels and YE Tianshi's theory of long-term illness entering collaterals. Combining the theory with modern medical knowledge， our team has condensed the dynamic pathogenesis model of deficiency （nutrient and blood aspects） and excess （pathogen） interacting in the blood collaterals of Yin aspect， the core feature of which is the four-dimensional interactions of cause （pathogen characteristics）， location （three Yin locations of diseases）， nature （deficiency and excess）， and potential （transmission trend）. The common pathology of infectious chronic diseases is reflected in interactions. That is， the interactions between nutrient and blood deficiency （immune exhaustion and metabolic disorder） and pathogen excess （pathogen persistence and fibrous hyperplasia） in the liver collaterals （Jueyin）， kidney collaterals （Shaoyin）， lung collaterals （Taiyin） and other blood collaterals of Yin aspect form the pathological damage characterized by immune inflammatory response-continuous tissue damage with excessive repair. Taking the inheritance and innovative development of classics as the main line， this paper systematically discusses the scientific connotation of the theory of pathogen invading nutrient and blood aspects and the paths of inheritance and innovation and clarifies the original significance of this theory in the chronic development of infectious diseases. Furthermore， taking clinical diseases as an example， this paper reflects the guiding value of this classical theory in the modern diagnosis and treatment of infectious diseases with integrated traditional Chinese and Western medicine and the application potential of this theory in solving complex medical problems through the construction of the innovative paradigm of precise diagnosis and treatment with integrated traditional Chinese and Western medicine.

Objective: To evaluate the safety and efficacy of the emergency infusion protocol for universal red blood cells by analyzing its clinical application in patients treated at our hospital's war trauma and emergency center. Methods: Data were collected from 133 patients who received universal red blood cell transfusion in the war trauma center of our hospital from January 2016 to December 2024. The basic information, universal red blood cell transfusion volume, compatible blood components, transfusion volume, blood routine (Hb, Hct), liver and kidney function (ALT, AST, TBil, DBil, creatinine, etc.) and coagulation function (PT, APTT, Fib, etc.) before and after transfusion were retrospectively analyzed. Results: Among the 133 patients who received a total of 374 units of universal red blood cells, the 24-hour survival rate was 62.4% (83/133). Spearman correlation analysis showed a positive correlation between shock index and universal red blood cell transfusion volume (r=0.283, P<0.05). Patients were stratified by universal red blood cell transfusion volume (≤ 3 U vs ≥ 4 U). The low volume group had less homotypic red blood cell transfusion volume and total transfusion volume at different time points, and the difference was statistically significant: within 2 h [2(2, 4)vs 4(3, 7), P=0.033<0.05], 0~24 h [6(4, 9) vs 8(6, 14), P=0.028<0.05], total transfusion volume [13(8, 20)vs 19(12, 35), P=0.021<0.05]. No acute hemolytic transfusion reaction occurred within 24 hours after transfusion of universal red blood cell. Conclusion: Universal red blood cells are safe for use in emergency treatment. Furthermore, the shock index combined with the volume of universal red blood cells transfused can predict subsequent transfusion requirements and enables the early reservation of compatible blood, thereby preventing delayed resuscitation.

Objective:To describe the clinical characteristics of a possible rare syndrome, the granulomatous mastitis(GM), erythema nodosum and arthritis syndrome (GMENA syndrome), by retrospective analyzing patients with both GM and erythema nodosum, with or without arthritis, and provide clinical evidence for further researchstudy.Methods:This study analyzed the demographic general information, clinical manifestations, laboratory tests results, medications, operations, and the first visits of cases collected from the Affiliated Hospital of Qingdao University between January 2015 and February 2024. All patients were diagnosed with both GM and erythema nodosum, with or without arthritis. The frequency, means and standard deviation were used to perform descriptive analysis.Results:Among the 22 cases, all of the GM were unilateral, and nodular erythema mainly appeared in both lower limbs 17 (77%). Eight (67%) patients had arthritis. Sixteen cases (80%) were reported forwith elevated white blood cells count, and 16 (84%) with elevated C-reactive protein level, 12(86%) patients were with elevated erythrocyte sedimentation rate. Two cases were associated with hyperprolactinemia. In the bacterial tests of the breast abscess, C orynebacterium kroppenstedtii, and one Staphylococcus epidermidis were detected in 1 case respectively. The department of breast surgery was the most frequently first visit (86%) medical service, and 14 cases (64%) visited the department of rheumatology and immunology. Four cases (18%) underwent abscess incision and drainage after ineffective medication and none of them were treated with glucocorticoids. Five cases with glucocorticoids and followed-up by the department of rheumatology and immunology were not operated and four in of them without recurrenc. Conclusion:GMENA syndrome may be a syndrome characterized by high inflammatory activity, cytokine activation, and often involves the breast, skin, and joint. The pathogenesis and treatment of this syndrome need to be investigated further.

Congenital heart disease (CHD) may result from various risk factors including genetic, epigenetic, and environmental elements. The parallel and synchronous development of the placenta and fetal heart establishes a regulatory relationship known as the placenta-heart axis. Placental insufficiency may impact fetal cardiac development, while abnormal cardiac development can conversely disrupt placental structure and function. This review examines the association between placental abnormalities and CHD, providing insights into the etiology and underlying mechanisms of CHD.

Objective To evaluate the efficacy and safety of amoxicillin-clavulanate(10∶1)for injection in the treatment of community-acquired pneumonia(CAP)in adult patients.Methods Eligible patients were randomized to receive amoxicillin-clavulanate(10∶1)2.2 g or ampicillin-sulbactam(2∶1)3.0 g via intravenous infusion q12h or q8h for 7 to 14 days.The primary endpoint was to the clinical efficacy 7-14 days after discontinuation of treatment.The secondary endpoints included microbiological efficacy and safety.Results All enrolled patients(n=324)were included in the full analysis set(FAS),specifically 165 patients receiving amoxicillin sodium-clavulanate potassium(10∶1)and 159 patients receiving ampicillin sodium-sulbactam sodium(2∶1).The clinical cure rate was 78.8％(130/165)for amoxicillin-clavulanate(10∶1)and 77.4％(123/159)for ampicillin-sulbactam 7-14 days after end of treatment(P＞0.05).The clinical cure rate was 87.5％(126/144)for amoxicillin-clavulanate(10∶1)and 87.4％(111/127)for ampicillin-sulbactam(2∶1)in per protocol set(P＞0.05).Therefore,amoxicillin-clavulanate(10∶1)was non-inferior to ampicillin-sulbactam in the primary endpoint in the treatment of CAP in adult patients.The overall bacterial eradication rate was 94.4％(34/36)for amoxicillin-clavulanate(10∶1)and 89.3％(25/28)for ampicillin-sulbactam(P＞0.05).The common study drug-related clinical adverse event were abnormalities of hepatic function in both the amoxicillin-clavulanate(10∶1)group(4.8％,8/165)and ampicillin-sulbactam group(3.1％,5/159)(P＞0.05).Conclusions Amoxicillin-clavulanate(10∶1)2.2 g Ⅳ infusion q12h or q8h for 7-14 days was noninferior to ampicillin-sulbactam in terms of clinical and microbiological efficacy in the treatment of CAP in adult patients.The safety of the two dosing regimens was comparable.

Objective:To develop the Motivation for Bedtime Procrastination Questionnaire for College Students(CS-MBPQ)and evaluate its validity and reliability.Methods:Based on literature analysis,interviews with severe bedtime procrastinators,and open-ended surveys with college students,the initial questionnaire was formed.A total of 389 college students were recruited to conduct item analysis and exploratory factor analysis.Additionally,691 college students were selected for confirmatory factor analysis,criterion validity testing,and internal consistency reliability analysis,and 132 of them were retested two weeks later.The subscale of behav-ioral intention from the Theory of Planned Behavior Questionnaire(TPBQ),Bedtime Procrastination Scale(BPS),and a self-made question for the frequency of bedtime procrastination were used as criterion tools.Results:The CS-MBPQ consists of 10 items,encompassing three factors:emotional need,external influence,and behavioral attitude,explaining 63.31％of the variance.Confirmatory factor analysis indicated that the three-factor structure model of CS-MBPQ fitted well(x2/df=4.90,RMSEA=0.07,CFI=0.96,TLI=0.94).The CS-MBPQ total scores and scores for each factor were positively associated with the score of intentions to sleep on time,BPS scores,and bed-time procrastination frequency(ICC=0.14-0.53,Ps＜0.05).The internal consistency reliabilities for CS-MBPQ and the three factors were 0.87,0.89,0.74,and 0.66,respectively,and the test-retest reliabilities(ICC)were 0.74,0.66,0.69,and 0.58,respectively.Conclusion:The Motivation for Bedtime Procrastination Questionnaire for College Students(CS-MBPQ)demonstrates good validity and reliability,which could be used as a tool to evaluate motivations for bedtime procrastination among Chinese college students.
