Objective:To investigate the efficacy and prognostic survival of pembrolizumab combined with apatinib and chemotherapy in the treatment of human epidermal growth factor receptor-2 (HER2)-negative advanced gastric cancer.Methods:Patients with HER2-negative advanced gastric cancer were selected from December 2019 to December 2022 as the study subjects. Forty-five patients who received chemotherapy therapy (fluorouracil+cisplatin) were randomly collected and included in control group, and 52 patients who were treated with pembrolizumab combined with apatinib were randomly selected and enrolled as observation group. The difference in short-term efficacy was compared. The levels of serum tumor markers and immune function (CD3 +, CD4 +, CD8 +, CD4 +/CD8 +) were recorded. The long-term efficacy and adverse reactions of patients were compared. Measurement data conforming to the normal distribution were expressed as xˉ± s, and the mean comparison between groups was performed by independent sample t test. Chi-square test was used to compare the rate or composition ratio among enumeration data. P<0.05 was considered statistically significant. Results:At 6 months after treatment, the disease control rate in observation group was significantly higher than that in control group (78.85% (41/52) vs 57.78% (26/45)) ( χ2=5.01, P=0.025), but there was no statistical significance in objective response rate between groups (36.54% (19/52) vs 24.45% (11/45)) ( χ2=1.65, P=0.199). The levels of pepsinogen I, tissue polypeptide specific antigen, carcinoembryonic antigen, carbohydrate antigen 199 and CD8 + in both groups were reduced after treatment, and the levels were lower in observation group than those in control group ( t=6.06, 6.78, 4.68, 11.21, 3.45, all P<0.001). The levels of CD3 +, CD4 + and CD4 +/CD8 + were enhanced significantly in the two groups, and the observation group had higher levels after treatment ( t values were 2.10, 3.74, and 5.19; P values were 0.028, <0.001, and <0.001). After 1 year of follow-up, the survival rate in observation group with 59.62% (31/52) was significantly higher than 37.78% (17/45) in control group ( χ2=4.60, P=0.032). The progression-free survival time ((10.22±1.62) months vs (8.13±1.57) months, t=6.43, P<0.001) and overall survival time ((11.62±1.84) months vs (9.73±1.71) months, t=5.21, P<0.001) in observation group were significantly longer compared to control group. There were no statistical differences in the incidence rates of bone marrow suppression ( χ2=1.92, P=0.165), hand-foot syndrome ( χ2=3.47, P=0.062), gastrointestinal reaction ( χ2=0.32, P=0.574), hypertension ( χ2=0.94, P=0.333) and proteinuria ( χ2=2.39, P=0.122) between the two groups. Conclusion:Compared with chemotherapy, pembrolizumab combined with apatinib shows good short-term efficacy and long-term efficacy in patients with HER2-negative advanced gastric cancer.

Autoimmune hepatitis (AIH) is a severe globally distributed liver disease that could occur at any age. Human menstrual blood-derived stem cells (MenSCs) have shown therapeutic effect in acute lung injury and liver failure. However, their role in the curative effect of AIH remains unclear. Here, a classic AIH mouse model was constructed through intravenous injection with concanavalin A (Con A). MenSCs were intravenously injected while Con A injection in the treatment groups. The results showed that the mortality by Con A injection was significantly decreased by MenSCs treatment and liver function tests and histological analysis were also ameliorated. The results of phosphoproteomic analysis and RNA-seq revealed that MenSCs improved AIH, mainly by apoptosis and c-Jun N-terminal kinase/mitogen-activated protein signaling pathways. Apoptosis analysis demonstrated that the protein expression of cleaved caspase 3 was increased by Con A injection and reduced by MenSCs transplantation, consistent with the TUNEL staining results. An AML12 co-culture system and JNK inhibitor (SP600125) were used to verify the JNK/MAPK and apoptosis signaling pathways. These findings suggested that MenSCs could be a promising strategy for AIH.

Objective:To investigate the effect and molecular mechanism of tumor necrosis factor-α-inducible protein 8-like 2(TIPE2)on lipopolysaccharide(LPS)or interleukin-4(IL-4)-induced phenotypic switch of adipose tissue macrophages(ATM).Methods:The expression levels of TIPE2, inducible nitric oxide synthase(iNOS), monocyte chemoattractant protein 1(MCP-1), CD206, and arginase 1(Arg-1)in the visceral adipose tissue of obese mice, TIPE2-knockout(KO)mice, and control mice were detected by immunohistochemistry, Western blotting, and real-time PCR(RT-qPCR). Peritoneal macrophages isolated from KO and wild-type mice and RAW 264.7 mouse macrophage cell line were cultured, and then stimulated with LPS(100 ng/mL)or IL-4(20 ng/mL)for 6 hours. The expression levels of TIPE2, iNOS, MCP-1, CD206, and Arg-1 were detected by Western blotting and RT-qPCR.Results:Obese mice showed down-regulated TIPE2 expression, up-regulated pro-inflammatory markers iNOS and MCP-1 expressions, and down-regulated anti-inflammatory markers CD206 and Arg-1 expressions. LPS decreased the expression of TIPE2 in RAW 264.7 cells and peritoneal macrophages from mice, increased the expression of the classically activated macrophages(M1 phenotype)markers iNOS and MCP-1, and decreased the expression of the substituting activated macrophages(M2 phenotype)markers CD206 and Arg-1. IL-4 increased the expression of TIPE2 in RAW 264.7 cells and peritoneal macrophages, decreased the expression of iNOS and MCP-1, and increased the expression of CD206 and Arg-1. During the M1 polarization of macrophages, LPS increased toll-like receptor(TLR4)expression as well as nuclear transcription factor κBα suppressor protein(IκBα) and NF-κB phosphorylations in macrophages. Knockout of TIPE2 further increased the expression of the TLR4/IκBα/NF-κB signaling pathway and M1 macrophage markers, and further reduced the expression of the M2 macrophage markers.Conclusion:TIPE2 regulates ATM phenotypic transformation through inhibition of the TLR4/IκBα/NF-κB signaling pathway, which ameliorates adipose tissue inflammation in obese states.
