ObjectiveTo investigate the antitumor effect and mechanism of Guiqi Yiyuan ointment on Lewis lung cancer mice based on the extracellular regulatory protein kinase (ERK) signaling pathway. MethodsA Lewis lung cancer mouse model was established. Except for the blank group, the model mice were randomly divided into the model group, Guiqi Yiyuan ointment low, medium, and high dose groups, and the extracellular ERK1/2 inhibitor group, with 10 mice per group. The Guiqi Yiyuan ointment was administered by gavage at doses of 1.75, 3.5, 7.0 g·kg-1·d-1 for the low, medium, and high dose groups, respectively. The ERK1/2 inhibitor group was given the ERK1/2 inhibitor LY3214996 (100 mg·kg-1·d-1) by gavage. The treatment was administered for 14 consecutive days, after which samples were collected. Tumor histopathological changes were observed using hematoxylin-eosin (HE) staining. Transmission electron microscopy was used to observe ultrastructural changes in tumor cells. Immunofluorescence was performed to measure the phosphorylation of ERK1/2 (p-ERK1/2) and the expression of programmed cell death ligand-1 (PD-L1) in tumor tissues. Western blot and real-time quantitative polymerase chain reaction (Real-time PCR) were used to detect the expression of p-ERK1/2, PD-L1, the autophagy marker Beclin-1, the autophagic protein p62, and the microtubule-associated protein light chains LC3Ⅰ and LC3Ⅱ at both the protein and gene levels. ResultsCompared with the model group, the average tumor weight was significantly reduced in the low and medium dose groups of Guiqi Yiyuan ointment (P<0.05), and markedly reduced in the high dose and inhibitor groups (P<0.01). Tumor cells in all treatment groups became progressively irregular, with ruptured nuclei and expanded areas of cell disintegration and necrosis. The number of organellar ablations in tumor tissues increased, and the number of autophagic vesicles also increased in all groups. The mean fluorescence intensity of p-ERK1/2 and PD-L1 was reduced in the low and medium dose groups of Guiqi Yiyuan ointment (P<0.05), and significantly reduced in the high dose and inhibitor groups (P<0.01). The mRNA expression of ERK1/2, PD-L1, Beclin-1, and p62 was reduced in the medium dose group (P<0.05), while LC3Ⅰ/Ⅱ mRNA expression was elevated (P<0.05). In the high dose and inhibitor groups, mRNA expression of ERK1/2, PD-L1, Beclin-1, and p62 was significantly reduced (P<0.01), while LC3Ⅰ/Ⅱ mRNA expression was significantly increased (P<0.01). Protein expression of p-ERK1/2, PD-L1, Beclin-1, and p62 was reduced in the medium dose group (P<0.05), and LC3Ⅰ/Ⅱ protein expression was elevated (P<0.05). In the high dose and inhibitor groups, protein expression of p-ERK1/2, PD-L1, Beclin-1, and p62 was significantly reduced (P<0.01), while LC3Ⅰ/Ⅱ protein expression was significantly elevated (P<0.01). ConclusionGuiqi Yiyuan ointment may inhibit the activation of the ERK signaling pathway, downregulate the expression of p-ERK1/2, promote autophagic flux in tumor cells, and regulate the expression of PD-L1, thereby exerting an inhibitory effect on tumor growth in Lewis lung cancer mice.

OBJECTIVE To re-evaluate the use of systematic evaluation/meta-analysis of anti-VEGF drugs in the treatment of diabetic macular oedema (DME), aiming to provide evidence-based support for the clinical application of this medication. METHODS A comprehensive search was conducted across a range of databases, including CNKI, Wanfang data, VIP, CBM, PubMed, Web of Science, Embase, and Cochrane Library. The objective was to identify systematic evaluation/meta-analysis of anti- VEGF drugs for DME, with search time from the inception of the databases to March 2024. The report quality, methodological quality, and evidence quality were assessed by using PRISMA2020 statement, AMSTAR2 scale and GRADE tool. A comprehensive analysis of systematic evaluation/meta-analysis results was also conducted. RESULTS A total of 22 articles were included. According to the PRISMA2020 statement evaluation, 13 studies provided relatively complete information (≥21 points), while 9 studies had information deficiencies (18-<21 points). The AMSTAR 2 scale evaluation revealed that 21 studies had very low methodological quality, and one study had low methodological quality. The GRADE tool evaluation showed that out of 89 outcome indicators, 28( 31.46%) were classified as high-quality evidence, 34( 38.20%) as moderate-quality evidence, 24( 26.97%) as low- quality evidence, and 3 (3.37%) as very low-quality evidence. The comprehensive quality analysis results demonstrated that, compared with laser photocoagulation, anti-VEGF drugs significantly enhanced the improvement in best-corrected visual acuity (BCVA), as well as significant change in retinal thickness at 1 and 6 months, and 1 and 2 years post-treatment, and also in BCVA and retinal thickness at 1, 3, and 6 months post-treatment (P<0.05). Compared with placebo, patients treated with anti-VEGF drugs showed significant improvement in BCVA after 1 year of treatment (P<0.05). However, when compared with corticosteroid drugs, patients treated with anti-VEGF drugs exhibited a significant increase in retinal thickness after 6 months of treatment (P<0.05). Compared with corticosteroid drugs, the incidence of adverse events related to the eyes, cataract formation and intraocular pressure were significantly decreased in patients treated with anti-VEGF drugs (P<0.05). Compared with laser photocoagulation, the incidence of ocular adverse events was significantly decreased in patients treated with anti-VEGF drugs, while the incidence of fatal adverse events was significantly increased (P<0.05). CONCLUSIONS Anti-VEGF therapy for DME may possess certain advantages in terms of efficacy and safety, but it is associated with a higher risk of fatal adverse events; the evidence included in systematic reviews/meta-analyses is of moderate to high quality.

ObjectiveTo explore the effects of Guiqi Yiyuan ointment combined with cisplatin on mice with Lewis lung cancer through the endoplasmic reticulum stress pathway and mitochondrial apoptosis pathway. MethodFifty SPF male C57BL/6 mice were randomly divided into the model group, cisplatin group (0.005 g·kg-1), and low, medium, and high dose groups of Guiqi Yiyuan ointment combined with cisplatin (0.005+1.6 g·kg-1, 0.005+3.3 g·kg-1, and 0.005+6.6 g·kg-1). Lewis cell suspension was inoculated under the axilla of mice in each group to construct the Lewis lung cancer xenograft mouse model. After continuous administration for 14 days, the mice were sacrificed. The body weight of the mice was measured, and the tumor weight was measured after the tumors were removed. The organ index and tumor inhibition rate were calculated. Hematoxylin-eosin ( HE) staining was used to observe the pathological changes in tumor tissue. Flow cytometry was used to detect the apoptosis rate of tumor cells and the ratio of reactive oxygen species (ROS). Western blot was used to detect the expression of glucose-regulated protein 78 (GRP78), phosphorylated activated protein kinase R-like endoplasmic reticulum kinase (p-PERK), activated transcription factor 4 (ATF4), and apoptosis protein C/EBP homologous protein (CHOP) in the endoplasmic reticulum stress pathway, as well as cysteine aspartate protease-9 (Caspase-9), B-cell lymphoma-2(Bcl-2), and Bcl-2 associated X protein(Bax) in the mitochondrial apoptosis pathway. ResultCompared with those in the model group, the mice in the groups of Guiqi Yiyuan Ointment combined with cisplatin had shinier fur and better mental response status. Tumor mass was reduced in all treatment groups (P<0.05), and tumor inhibition rate was increased in all treatment groups (P<0.05). The thymus and spleen indices of the combined group were increased (P<0.05), and obvious pathological changes were observed in the tumor tissue of all treatment groups, with a gradual decrease in heteromorphism. Destruction of massive tumor tissue was observed in the high-dose combined group, and the apoptosis rate and ROS generation rate of tumor cells were increased in all treatment groups (P<0.05). The protein expression level of Bcl-2 in the tumor tissue gradually decreased (P<0.05), while the protein expression levels of GRP78, p-PERK, ATF4, CHOP, Bax, and Caspase-9 were significantly increased (P<0.05). Compared with the cisplatin group, tumor mass was reduced in the combined group (P<0.05), and tumor inhibition rates in the low and high-dose combined groups were increased (P<0.05). The thymus index, spleen index, apoptosis rate of tumor cells, and ROS ratio in the combined group were significantly increased (P<0.05), while the protein expression levels of GRP78, p-PERK, Bax, and Caspase-9 were increased in the low and high-dose combined groups (P<0.05). The protein expression levels of ATF4 and CHOP were increased in the combined group (P<0.05), while the expression level of Bcl-2 protein gradually decreased (P<0.05). ConclusionGuiqi Yiyuan ointment combined with cisplatin can exert anti-tumor effects in mice with Lewis lung cancer, reduce tumor mass, increase tumor inhibition rate, and induce apoptosis of lung cancer cells. Its mechanism may be related to the regulation of the endoplasmic reticulum stress pathway and mitochondrial apoptosis pathway.

cAMP response element binding protein (CREB) is an eukaryotic intranuclear protein widely expressed in a variety of organs, and its activation increases the transcriptional activity of downstream genes and promotes the expression of related genes. The neuronal function of CREB is related to many intracellular processes, such as proliferation, differentiation, survival, long-term synaptic potentials, neurogenesis and neuronal plasticity. Increasing evidence has demonstrated that CREB plays an important role in the stroke development and therefore, it may serve as a potential target for stroke therapy. Since some herbal medicines as well as their active ingredients regulate the CREB signaling, this article will summarize the role of CREB signaling pathway in stroke pathophysiology. The research progress of traditional Chinese medicine and its active ingredients modulating CREB activity will also be discussed, with the aim of providing the basis and reference for the future research and development of natural medicines against stroke.
