Acute lung injury （ALI） is a life-threatening condition characterized by uncontrolled pulmonary inflammatory responses， presenting high morbidity and mortality rates that pose serious threats to patient health. The pathogenesis of ALI involves complex interactions among pathological mechanisms including immune-inflammatory responses， disruption of the alveolar-capillary barrier， mesenchymal stem cell dysfunction， metabolic disorders， ferroptosis， and alterations in the gut microbiota. The dysregulation of programmed cell death （PCD） has increasingly emerged as a research focus. PCD represents a genetically regulated autonomous process of cell death， crucial for maintaining the internal stability of organisms. Recent studies indicate that multiple PCD modes， including apoptosis， pyroptosis， necroptosis， autophagy， and ferroptosis， participate in the development and progression of ALI by mediating pathological processes such as alveolar epithelial cell injury and vascular endothelial barrier disruption. Current therapeutic approaches for ALI encompass lung-protective ventilation， body fluid management， mesenchymal stem cell therapy， and pharmacological interventions. While these measures may alleviate clinical symptoms， they remain unable to reverse the pathological progression of lung injury. Traditional Chinese medicine （TCM） possesses the unique advantages of a holistic perspective and syndrome differentiation-based treatment， achieving breakthrough progress in targeted PCD intervention for ALI. It can mitigate pulmonary tissue injury by suppressing inflammatory responses， regulating immune function， and improving coagulation disorders， thereby delaying the onset and progression of ALI. This paper delves into the molecular mechanisms of PCD in ALI， systematically reviewing the effects of TCM extracts， active constituents （terpenoids， saponins， flavonoids， and phenols）， and compound formulas （e.g.， Qingjie Huagong prescription， Maxing Kugan Tang， and Yifei Jianpi prescription） in improving pulmonary epithelial cell function and mitigating lung injury by modulating PCD pathways. This review aims to provide theoretical underpinnings and novel directions for drug development in the clinical prevention and treatment of ALI.

Objective To explore brain activity features during the resting state in alcohol dependent individuals,and study the relationship between the brain activity features and alcohol dependent individuals' clinical symptoms.Methods Twenty-four alcohol dependent individuals and 22 healthy control subjects,well matched in gender,age,education and handedness,were enrolled as the alcohol dependent group and control group respectively.AGE 3.0 T MR scanner was used to acquire all the subjects' resting state data. DPARSF software was used to process resting functional MRI data,and then the whole brain fractional amplitudes of low frequency fluctuation (fALFF) data were acquired.Two-sample t test statistical analysis was made to access fALFF difference between the two groups. Results In comparison with the control group,the alcohol dependent group showed reduced fALFF in bilateral medial prefrontal gyrus,right inferior occipital gyrus,left precuneus,left inferior temporal gyrus,and left posterior lobe of cerebellum (0.64-1.69 vs.0.87-1.78,t =- 4.23- - 2.79,P ＜ 0.05 ). fALFF was increased in the alcohol dependent group at the anterior cingulate,bilateral inferior frontal gyrus,right middle frontal gyrus,bilateral insular lobe,bilateral dorsal thalamus ( 0.86-1.82 vs. 0.76-1.58,t =3.56-3.96,P ＜ 0.05 ).Conclusion Alcohol dependent individuals had abnormal activity at the bilateral prefrontal lobe,anterior cingulate,bilateral dorsal thalamus,bilateral insular lobe,left posterior lobe of cerebellum et al,during the resting state,and these abnormal activities might be related with clinical manifestation and pathophysiology.
