BACKGROUND:
This study aimed to investigate programmed death-ligand 1 tumor proportion score in predicting the safety and efficacy of PD-1/PD-L1 antibody-based therapy in treating patients with advanced non-small cell lung cancer (NSCLC) in a real-world setting.
METHODS:
This retrospective, multicenter, observational study enrolled adult patients who received PD-1/PD-L1 antibody-based therapy in China and met the following criteria: (1) had pathologically confirmed, unresectable stage III-IV NSCLC; (2) had a baseline PD-L1 tumor proportion score (TPS); and (3) had confirmed efficacy evaluation results after PD-1/PD-L1 treatment. Logistic regression, Kaplan-Meier analysis, and Cox regression were used to assess the progression-free survival (PFS), overall survival (OS), and immune-related adverse events (irAEs) as appropriate.
RESULTS:
A total of 409 patients, 65.0% ( n = 266) with a positive PD-L1 TPS (≥1%) and 32.8% ( n = 134) with PD-L1 TPS ≥50%, were included in this study. Cox regression confirmed that patients with a PD-L1 TPS ≥1% had significantly improved PFS (hazard ratio [HR] 0.747, 95% confidence interval [CI] 0.573-0.975, P = 0.032). A total of 160 (39.1%) patients experienced 206 irAEs, and 27 (6.6%) patients experienced 31 grade 3-5 irAEs. The organs most frequently associated with irAEs were the skin (52/409, 12.7%), thyroid (40/409, 9.8%), and lung (34/409, 8.3%). Multivariate logistic regression revealed that a PD-L1 TPS ≥1% (odds ratio [OR] 1.713, 95% CI 1.054-2.784, P = 0.030) was an independent risk factor for irAEs. Other risk factors for irAEs included pretreatment absolute lymphocyte count >2.5 × 10 9 /L (OR 3.772, 95% CI 1.377-10.329, P = 0.010) and pretreatment absolute eosinophil count >0.2 × 10 9 /L (OR 2.006, 95% CI 1.219-3.302, P = 0.006). Moreover, patients who developed irAEs demonstrated improved PFS (13.7 months vs. 8.4 months, P <0.001) and OS (28.0 months vs. 18.0 months, P = 0.007) compared with patients without irAEs.
CONCLUSIONS
A positive PD-L1 TPS (≥1%) was associated with improved PFS and an increased risk of irAEs in a real-world setting. The onset of irAEs was associated with improved PFS and OS in patients with advanced NSCLC receiving PD-1/PD-L1-based therapy.

Background and objective Neoantigen reactive T cell(NRT)has the ability to inhibit the growth of tumors expressing specific neoantigens.However,due to the difficult immune infiltration and the inhibition of tumor micro en-vironment,the therapeutic effect of NRT in solid tumors is limited.In this study,we designed NRT cells(7×19 NRT)that can express both interleukin-7(IL-7)and chemokine C-C motif ligand 19(CCL19)in mouse lung cancer cells,and evaluated the difference in anti-tumor effect between 7×19 NRT cells and conventional NRT cells.Methods We performed next-generation sequencing and neoantigen prediction for mouse Lewis lung carcinoma(LLC),prepared RNA vaccine,cultured NRT cells,constructed retroviral vectors encoding IL-7 and CCL19,transduced NRT cells and IL-7 and CCL19 were successfully ex-pressed,and 7×19 NRT was successfully obtained.The anti-tumor effect was evaluated in vivo and in vitro in mice.Results The 7×19 NRT cells significantly enhanced the proliferation and invasion ability of T cells by secreting IL-7 and CCL19,achieved significant tumor inhibition in the mouse lung cancer and extended the survival period of mice.The T cell infiltration into tumor tissue and the necrosis of tumor tissue increased significantly after 7×19 NRT treatment.In addition,both 7×19 NRT treatment and conventional NRT treatment were safe.Conclusion The anti-solid tumor ability of NRT cells is significantly enhanced by the arming of IL-7 and CCL19,which is a safe and effective genetic modification of NRT.

Rheumatoid arthritis (RA) is a chronic inflammatory autoimmune disease caused by inflammatory cells. Various inflammatory cells involved in RA include fibroblast-like synoviocytes, macrophages, CD4+T-lymphocytes, B lymphocytes, osteoclasts and chondrocytes. The close interaction between various inflammatory cells leads to imbalance of immune response and disorder of the expression of mRNA in inflammatory cells. It helps to drive production of pro-inflammatory cytokines and stimulate specific antigen-specific T- and B-lymphocytes to produce autoantibodies which is an important pathogenic factor for RA. Competing endogenous RNA (ceRNA) can regulate the expression of mRNA by competitively binding to miRNA. The related ceRNA network is a new regulatory mechanism for RNA interaction. It has been found to be involved in the regulation of abnormal biological processes such as proliferation, apoptosis, invasion and release of inflammatory factors of RA inflammatory cells. Understanding the ceRNA network in 6 kinds of RA common inflammatory cells provides a new idea for further elucidating the pathogenesis of RA, and provides a theoretical basis for the discovery of new biomarkers and effective therapeutic targets.

ObjectiveTo evaluate the lipid-lowering activity of Quansanqi tablets(QSQ), an innovative new drug of Panax notoginseng. MethodMice and golden hamsters were used to establish a hyperlipidemia model by injecting egg yolk milk and feeding high-fat diets. The levels of total cholesterol (TC),triglyceride (TG),low-density lipoprotein cholesterol (LDL-C), and high-density lipoprotein cholesterol (HDL-C) were detected, and liver function indicators [alanine aminotransferase (ALT), aspartate amino-transferase (AST), and alkaline phosphatase (ALP)] of golden hamsters were detected. Hematoxylin-eosin (HE) staining was used to observe the degree of liver injury. In the experiments, a normal group, a model group, an atorvastatin calcium group, and low-, medium-, and high-dose QSQ groups (0.32, 0.64, 1.28 g·kg-1 for mice, and 0.16, 0.32, 0.64 g·kg-1 for golden hamsters) were set up. ResultCompared with the normal group, the acute hyperlipidemia model mice showed increased TC, TG, and LDL-C levels (P<0.01), and the hyperlipidemia model mice showed increased TC and LDL-C levels (P<0.01). Additionally, the hyperlipidemia model golden hamsters showed increased serum TC, TG, LDL-C, ALT, AST, and ALP levels (P<0.05, P<0.01). HE staining indicated the presence of fat accumulation in the liver, accompanied by inflammatory reactions. Compared with the model group, QSQ of various doses could reduce TC, TG, and LDL-C levels in acute hyperlipidemia model mice (P<0.05, P<0.01), and the high-dose QSQ could reduce TC and LDL-C levels (P<0.01) and increase HDL-C level (P<0.05) in hyperlipidemia model mice, as well as reduce TC, TG, and LDL-C levels in hyperlipidemia model golden hamsters (P<0.05, P<0.01), especially in the first two weeks. In addition, atorvastatin calcium could further increase ALT, AST, and ALP levels (P<0.05, P<0.01) and aggravate liver function damage, while low-dose QSQ could reduce ALT, AST, and ALP (P<0.05), and medium- and high-dose QSQ did not cause further liver function damage. ConclusionQSQ have a significant lipid-lowering effect on different hyperlipidemia model animals and can improve liver function and liver injury.
