During infection, they induce multiple forms of programmed cell death (PCD), which play pivotal roles in viral replication, dissemination, and host immune responses, thereby profoundly influencing the viral life cycle and disease progression. On one hand, PCD facilitates the clearance of infected cells, restricts viral spread, and activates host immune defenses, thereby enhancing antiviral immunity. On the other hand, excessive or dysregulated cell death may lead to tissue damage and immune imbalance, creating a microenvironment conducive to viral replication and exacerbating disease severity. For instance, apoptosis-mediated by both intrinsic and extrinsic pathways-contributes to infection control but may also be hijacked by viruses to promote dissemination. Pyroptosis, driven by inflammasome activation, triggers lytic cell death and the release of pro-inflammatory cytokines. Necroptosis, mediated by the RIPK1-RIPK3-MLKL signaling axis, and pyroptosis both amplify innate immune responses but may concurrently induce inflammatory dysregulation. Immunogenic cell death (ICD), characterized by the release of damage-associated molecular patterns (DAMPs) and neoantigens, activates antigen-specific immune responses and holds therapeutic potential for antiviral and antitumor interventions. Emerging evidence suggests that ferroptosis, through the modulation of iron metabolism and associated transporters, may also participate in viral replication and infected cell clearance.

Patients were divided into an observation group (Feigan granules combined with conventional Western medicine) and a control group (conventional Western medicine) based on whether they used Feigan granules. Main symptoms (including fever, cough and sore throat) and secondary symptoms (including chest tightness, poor appetite, muscle soreness and dry mouth) were evaluated with traditional Chinese medicine (TCM) symptom scale on the first day of the patient's visit and the third day after treatment. The degrees of improvement in the TCM symptom scores before and after treatment were compared using the paired rank-sum test, and the differences in the overall symptom efficacy index between two groups were compared using the Wilcoxon test.</p><p><strong>Results: </strong>A total of 217 influenza patients were included.

The median difference in the main symptom score before and after treatment in the study and the control groups was 7 points (95%<i>CI</i>: 6.0-8.0) and 6 points (95%<i>CI</i>: 6.0-8.0), respectively; the median difference in the secondary symptom score was 3 points (95%<i>CI</i>: 2.0-4.0) in both groups. The median difference in the total score was 9 points (95%<i>CI</i>: 8.0-10.5) and 8 points (95%<i>CI</i>: 7.0-10.0) in the study and control groups, respectively.
