ObjectiveTo evaluate pharmacological effects of Shengmai injection(SMI)on cerebral ischemia and study its neuroprotective mechanism. MethodsMale specific pathogen-free (SPF) Sprague-Dawley (SD) rats were randomly divided into a sham group, a model group, a low-dose SMI group(3 mL·kg-1), a middle-dose SMI group(6 mL·kg-1), a high-dose SMI group(12 mL·kg-1), and a Ginaton group(4 mL·kg-1)according to the random number table method, with 12 rats in each group. The rat model of cerebral ischemia-reperfusion(MCAO/R)was prepared via the suture method. The administration groups were intraperitoneally injected with corresponding concentrations of SMI or Ginaton injection after reperfusion, which was conducted for 3 consecutive days. The sham group and model group were administered the equivalent volume of physiological saline. The pharmacological effects of SMI on brain injury in MCAO/R rats were evaluated by neurological function scores, cerebral infarction area, hematoxylin-eosin (HE) staining, Nissl staining, terminal deoxynucleotidyl transferase dUTP nick-end labeling (TUNEL) staining, and Western blot. The dominant link and key protein of SMI treating cerebral injury were explored using proteomic analysis. The related mechanisms of SMI were further validated using enzyme-linked immunosorbent assay (ELISA), Western blot, and chloride ion fluorescence probe with oxygen-glucose deprivation/reoxygenation(OGD/R)-treated PC12 cells and MCAO/R rats. ResultsCompared with the sham group, the model group showed significantly increased neurological function scores, cerebral infarction area, neuronal apoptosis rate, and expression levels of apoptosis related proteins (P<0.05, P<0.01)and significantly decreased density of Nissl bodies and neurons(P<0.01). Compared with the model group, the SMI groups exhibited significantly decreased neurological function scores, cerebral infarction area, neuronal apoptosis rate, and expression levels of apoptosis related proteins (P<0.05, P<0.01)and significantly increased density of Nissl bodies and neurons (P<0.05). The proteomic analysis results showed that oxidative stress and inflammatory response were important processes of SMI intervening in MCAO/R injury, and the chloride intracellular channel protein 1 (CLIC1) was one of key proteins in its action network. The levels of representative indicators of oxidative stress and inflammatory response in the MCAO/R rats of the SMI groups were significantly reduced, compared with those in the model group(P<0.05, P<0.01), and the expression levels of CLIC1 and downstream NOD-like receptor protein 3 (NLRP3) decreased (P<0.01). In addition, the experimental results based on the OGD/R PC12 cells showed that SMI significantly increased the cell survival rate(P<0.01) and significantly decreased the intracellular chloride ion concentration(P<0.05). ConclusionSMI has neuroprotective effects. Oxidative stress and inflammatory response are key processes of SMI intervening in MCAO/R injury. The potential mechanism is closely related to the regulation of CLIC1.

Purpose:
This study aimed to investigate the molecular characteristics associated with better prognosis in breast cancer.
Methods:
We performed targeted sequencing of 962 genes in 56 samples, categorizing them into long-term and short-term survival groups as well as chemotherapy-sensitive and chemotherapy-resistant groups for further analyses.
Results:
The results indicated that the tumor mutational burden values were significantly higher in the short-term survival and chemotherapy-resistant groups (p = 0.008 and p = 0.003, respectively). Somatic mutation analysis revealed that the mutation frequencies of BCL9L and WHSC1 were significantly lower in the long-term survival group than those in the short-term survival group (p = 0.029 and p = 0.024, respectively). CREB-regulated transcription coactivator 1 (CRTC1) mutations occurred significantly more frequently in the chemotherapy-resistant group (p = 0.027) and were associated with shorter progression-free survival (p = 0.036).Signature weighting analysis showed a significant increase in Signature.3, which is associated with homologous recombination repair deficiency in the chemotherapy-sensitive group (p = 0.045). Conversely, signatures related to effective DNA repair mechanisms, Signature.1 and Signature.15, were significantly reduced (p = 0.002 and p < 0.001, respectively). Kyoto Encyclopedia of Genes and Genomes pathway analysis indicated that gene mutations were significantly enriched in the JAK-STAT signaling pathway.
Conclusion
This study, through intergroup comparative analysis, found that immunotherapy (using programmed death 1/programmed death-ligand 1 inhibitors) may improve the prognosis of patients with short survival and chemotherapy resistance. Additionally, the study revealed that mutations in BCL9L and WHSC1 could serve as biomarkers for breast cancer prognosis, while CRTC1 mutations and Signature.3 could predict chemotherapy response. The study also found that the JAK-STAT pathway might be a potential therapeutic target for chemotherapy resistance. Therefore, this study identifies molecular characteristics that influence the prognosis of breast cancer patients, providing important theoretical insights for the development of personalized treatment strategies.
