Infection (80 patients, 80.8%) was the most common reason for admission, with 47 cases being pulmonary infections. Of all of the 99 patients, 73 (73.7%) presented with persistent lymphocytopenia (lymphocyte count &lt; 1.1 × 10⁹/L from the day of ICU admission through to day 7), with 33 and 40 presenting moderate (lymphocyte count 0.6–1.1 × 10⁹/L) and severe persistent lymphopenia (lymphocyte count ≤ 0.6 × 10⁹/L), respectively.

Patients with severe persistent lymphopenia were associated with higher 28-day ICU mortality (87.5% vs. 42.4% vs. 7.7%, <i>p</i> &lt; 0.001) versus those with moderate and without persistent lymphopenia. Multivariable logistic regression analysis revealed that the number of organs involved, APACHE-II score, and persistent lymphopenia were independent risk factors for 28-day mortality in patients with MODS.

In clinical practice, Jian Pi Hua Tan Fang (JPHTF) has been shown to be effective in preventing recurrences and metastases caused by gastric cancer. Yet, the treatment process remains unknown.

Molecular docking analysis showed that quercetin, formononetin, and luteolin, which are the main active ingredients, exhibit high binding affinity to the central targets PI3K, AKT, and mTOR. In vitro experiment, the JPHTF-containing serum has a significant alleviating effect on reversing trastuzumab resistance and cell apoptotic and proliferation of NCI-N87/TR.

Conversely, anti-apoptotic miRNAs, including miR-21, are upregulated, further disrupting the delicate balance of immune cell apoptosis.
