Metabolic reprogramming is a key characteristic of hepatocellular carcinoma， and abnormal fatty acid metabolism is closely associated with tumor immune escape. This article systematically reviews the molecular mechanisms of fatty acid metabolic reprogramming in hepatocellular carcinoma， focusing on key enzymes and their transcriptional regulatory networks within de novo lipogenesis and fatty acid oxidation pathways. This article also analyzes the metabolic heterogeneity between β-catenin-mutant hepatocellular carcinoma and AXIN1-mutant hepatocellular carcinoma and their therapeutic implications， summarizes the multidimensional mechanisms by which the lipid microenvironment regulates immune cell function， and reviews the targeted therapeutic strategies for different molecular subtypes of hepatocellular carcinoma.

Based on cancer collateral theory， this paper proposes toxin-stasis accumulation in collaterals and yin deficiency with toxin hyperactivity as the core pathogenesis of postoperative recurrence of triple-negative breast cancer. Impaired qi transformation in collateral and depletion of yin interact， contributing to toxin-stasis binding， inadequate collateral nourishment， and unrestrained yang activity. The temporal dimension emphasizes yin deficiency with toxin hyperactivity and early reactivation of latent toxin； the spatial dimension emphasizes toxin-stasis accumulation and dissemination through collaterals. Treatment follows the principle of regulating qi and resolving collaterals. Before recurrence， emphasis is placed on nourishing collaterals to restrain latent toxin； after recurrence， on resolving binding while protecting collaterals. Herbal combinations are further tailored to disorders of qi， blood， and fluid collaterals and to the sites of dissemination， integrating treatment according to recurrence status and affected collateral systems. These theoretical propositions are intended to inform clinical reasoning and require clinical validation.

Cemental tear is a rare and indetectable condition unless obvious clinical signs present with the involvement of surrounding periodontal and periapical tissues. Due to its clinical manifestations similar to common dental issues, such as vertical root fracture, primary endodontic diseases, and periodontal diseases, as well as the low awareness of cemental tear for clinicians, misdiagnosis often occurs. The critical principle for cemental tear treatment is to remove torn fragments, and overlooking fragments leads to futile therapy, which could deteriorate the conditions of the affected teeth. Therefore, accurate diagnosis and subsequent appropriate interventions are vital for managing cemental tear. Novel diagnostic tools, including cone-beam computed tomography (CBCT), microscopes, and enamel matrix derivatives, have improved early detection and management, enhancing tooth retention. The implementation of standardized diagnostic criteria and treatment protocols, combined with improved clinical awareness among dental professionals, serves to mitigate risks of diagnostic errors and suboptimal therapeutic interventions. This expert consensus reviewed the epidemiology, pathogenesis, potential predisposing factors, clinical manifestations, diagnosis, differential diagnosis, treatment, and prognosis of cemental tear, aiming to provide a clinical guideline and facilitate clinicians to have a better understanding of cemental tear.

With the growing emphasis on maternal and child oral health, the significance of managing oral health across preconception, pregnancy, and infancy stages has become increasingly apparent. Oral health challenges extend beyond affecting maternal well-being, exerting profound influences on fetal and neonatal oral development as well as immune system maturation. This expert consensus paper, developed using a modified Delphi method, reviews current research and provides recommendations on maternal and child oral health management. It underscores the critical role of comprehensive oral assessments prior to conception, diligent oral health management throughout pregnancy, and meticulous oral hygiene practices during infancy. Effective strategies should be seamlessly integrated across the life course, encompassing preconception oral assessments, systematic dental care during pregnancy, and routine infant oral hygiene. Collaborative efforts among pediatric dentists, maternal and child health workers, and obstetricians are crucial to improving outcomes and fostering clinical research, contributing to evidence-based health management strategies.

Objective To explore the latent profile of health-promoting lifestyle in patients with lumbar disc herniation treated conservatively and analyze its influencing factors,so as to provide reference for the develop-ment of targeted interventions.Methods Patients with conservative treatment of Lumbar Disc Herniation at the orthopedic outpatient clinic of a tertiary hospital in Guangzhou from March to December 2024 were selected as study subjects.General Information Questionnaire,Health-Promoting Lifestyle Profile Revised-Ⅱ,Visual Analogue Scale,Oswestry Disability Index and Social Support Rating Scale were used for the investigation.Latent profile analysis was used to explore the potential categories of health-promoting lifestyle in patients with lumbar disc her-niation and the influencing factors were identified by univariate analysis and disordered multiple logistic regression analysis.Results A total of 422 lumbar disc herniation patients treated conservatively were included and the score of Health-Promoting Lifestyle Profile Revised-Ⅱ Scale was(102.44±13.19)points.The health-promoting lifestyle of patients with lumbar disc herniation can be divided into three potential profile:low health promotion group-low responsibility and less exercise type(18.7%),balanced health promotion group(51.7%)and high health promotion group-spiritual social leading type(29.6%).The results of logistic regression analysis showed that course of disease,oswestry disability index,social support level and take regular physical exercise are the influenc-ing factors of health-promoting lifestyle in patients with conservative treatment of lumbar disc herniation(P<0.05).Conclusions There is heterogeneity in the health-promoting lifestyle in patients with conservative treat-ment of lumbar disc herniation.Nursing staff can carry out targeted interventions according to the latent profile type of health-promoting lifestyle in lumbar disc herniation patients treated conservatively to improve their health-promoting lifestyle.

Objective To explore the optimization and effect analysis method of rational drug use pre-prescription review rule base for traditional Chinese medicine(TCM).Methods The rules for the modules including indications,dosage range,incompatibility,administration route and repeated drug use of TCM decoction pieces and Chinese patent medicine were set to improve pre-prescription review rule base.The prescription rationality rate and intervention effectiveness rate to evaluate effect by χ2 test before and after the system optimization.Results After the optimization of pre-prescription review rule base for TCM,the rate of prescription rationality of the hospital increased from approximately 78.19%to 94.50%,and the rate of intervention effectiveness increased from approximately 82.80%to 97.15%.There were statistically significant differences in prescription rationality and intervention effectiveness rate between pre-and post-optimization groups(P＜0.05).Conclusion According to the current pre-prescription status of the hospital,optimizing pre-prescription review rules of TCM can improve the applicability of the review system for TCM prescriptions,and enhance the pre-prescription accuracy and the level of rational medication.However,rules optimization on other modules still needs to be further improved.

Objective This study established a qualitative and quantitative detection method for 9 new synthetic cannabinoids in e-cigarette oil using liquid chromatography-high resolution mass spectrometry.Methods E-cigarette oil was extracted with methanol,concentrated by nitrogen blowing under a water bath at 60℃,and separated using an Acquity UPLC? HSS T3(100 mm×2.1 mm,1.8 μm)column.Gradient elution was performed with ammonium acetate buffer solution(20 mmol/L)containing 0.1%formic acid and acetonitrile as the mobile phase.Detection was carried out in the positive ion mode of the HESI ion source using DDA(FullScan+dd-MS2)mode.Quantification was performed using the external standard method based on precise precursor ion peak areas,while qualitative analysis relied on retention times and characteristic fragment ions.Results The results showed that the standard curves of all 9 synthetic cannabinoids in blank e-cigarette oil matrix exhibited good linearity with R2 values>0.999.The limits of detection ranged from 0.0001 to 0.01 μg/g,and the limits of quantification ranged from 0.0003 to 0.03 μg/g.Recovery rates at low,medium,and high spiking levels in blank e-cigarette oil matrix ranged from 75.7%to 115%,with relative deviations<8.5%.Conclusion This method features a short instrument detection time of only 10 min,relatively simple operation,low detection limits,high accuracy,and good precision,making it applicable for rapid screening and quantitative analysis of synthetic cannabinoids in e-cigarette oil.
