Visfatin,also known as nicotinamide phosphoribosyl transferase(NAMPT)or pre-B-cell colony-enhancing factor,is a proinflam-matory adipokine.Its immunomodulatory effects are closely associated with its pro-inflammatory activity,influencing the secretion of vari-ous cytokines and the function of immune cells.Visfatin exerts pro-tumorigenic effects in most cancers.The tumor immune microenviron-ment(TIME)comprises immune cells within the tumor tissue and an array of secreted cytokines.Growing evidence suggests that visfatin plays a regulatory role in the TIME by promoting inflammatory responses and modulating the polarization of immune cells,their secretory functions,surface protein expression,and energy metabolism,thereby influencing cancer progression.These newly discovered mechanisms provide a critical foundation for the application of NAMPT inhibitors(NAMPTi)in cancer immunotherapy.This review summarizes recent ad-vances in understanding the role of visfatin in tumor immunology and explores the therapeutic potential of NAMPTi in oncology.

Objective To investigate the correlation between intraplaque neovascularization(IPN)parameters using ultrasound lo-calization microscopy(ULM)and pathological results.Methods Atherosclerosis of the carotid artery in rabbit was induced using balloon catheter damage and a high-cholesterol diet.ULM technology was used to measure the IPN,and the parameters of neovascularization density,diameter,distortion and velocity were quantified,and compared with pathological results,to evaluate the reliability of ULM tech-nique in detecting and measuring the parameters of IPN.Results ULM technology can perform ultra-high resolution imaging of the IPN in rabbit carotid atherosclerotic plaques,and can accurately measured the density of IPN.The correlation with pathological diagnosis was good(r=0.915,P＜0.05).Conclusion ULM technique has a certain reliability in detecting the IPN in rabbit carotid atherosclerotic plaque.

BACKGROUND: With the aging of the population and the increased importance of lung cancer screening, the number of early-stage lung cancer patients has been on the rise in recent years, which can be classified into operable early-stage lung cancer and inoperable early-stage lung cancer. The most common pathological type is non-small cell lung cancer (NSCLC). Stereotactic body radiation therapy (SBRT) is the optimal treatment for inoperable early-stage NSCLC. The aim of this study was to investigate the prognosis of early-stage NSCLC patients treated with SBRT and its influencing factors in order to reduce the side effects of radiotherapy and improve the survival and quality of life. METHODS: Clinical data and follow-up outcomes of early-stage NSCLC patients treated with SBRT in our hospital from August 2010 to August 2020 were collected. Kaplan-Meier method was used to assess the prognosis, and the Cox proportional risk model was used for multivariate prognostic analysis. RESULTS: A total of 165 patients were included with a median follow-up time of 43.2 (range: 4.8-132.1) mon. The local control (LC) rates at 1-yr, 2-yr and 5-yr were 98.1%, 94.8% and 86.5% respectively. Karnofsky performance status (KPS) score greater than 80 was an independent prognostic factor for LC (P=0.02). The overall survival (OS) rates at 1-yr, 2-yr and 5-yr were 97.6%, 93.0% and 68.9% respectively. A biological equivalent dose when α/β=10 (BED10) greater than 132 Gy was an independent prognostic factor for OS (P=0.04). Progression-free survival (PFS) rates at 1-yr, 2-yr and 5-yr were 93.3%, 79.5% and 55.3% respectively. The distance metastasis free survival (DMFS) rates at 1-yr, 2-yr and 5-yr were 94.5%, 83.2% and 58.4% respectively. BED10 greater than 150 Gy was an independent prognostic factor for DMFS (P=0.02). The regional control (RC) rates at 1-yr, 2-yr and 5-yr were 98.8%, 95.4% and 87.9% respectively. CONCLUSIONS SBRT is effective in treating early-stage NSCLC. KPS greater than 80 is an independent prognostic factor for LC; BED10 greater than 132 Gy is an independent prognostic factor for OS; BED10 greater than 150 Gy is an independent prognostic factor for DMFS.

Background: The treatment of trigeminal neuralgia remains a challenging issue.Stem cells from human exfoliated deciduous teeth (SHED) provide optimized therapy for chronic pain. This study aimed to investigate the mechanisms underlying the attenuation of trigeminal neuralgia by SHED. Methods: Trigeminal neuralgia was induced by chronic constriction injury of the infraorbital nerve. The mechanical threshold was assessed after model establishment and local SHED transplantation. Endoplasmic reticulum (ER) morphology and Caspase12 expression in trigeminal ganglion (TG) was evaluated as well. BiP expression was observed in PC12 cells induced by tunicamycin. Results: The local transplantation of SHED could relieve trigeminal neuralgia in rats.Further, transmission electron microscopy revealed swelling of the ER in rats with trigeminal neuralgia. Moreover, SHED inhibited the tunicamycin-induced up-regulated expression of BiP mRNA and protein in vitro. Additionally, SHED decreased the up-regulated expression of Caspase12 mRNA and protein in the TG of rats caused by trigeminal neuralgia after chronic constriction injury of the infraorbital nerve mode. Conclusions This findings demonstrated that SHED could alleviate pain by relieving ER stress which provide potential basic evidence for clinical pain treatment.

To explore the significance of Erbin expression in esophageal squamous cell carcinoma (ESCC) and its relation-ship with patient prognosis. Methods: Erbin expression in a tissue chip containing samples from 299 cases were examined using immu-nohistochemistry; in addition, the relationship between Erbin expression and clinical-pathological parameters and patient survival time were also analyzed. Cox regression was used to predict the risk of clinical-pathological parameters. The mRNA and protein expres-sion of Erbin was also determined in 25 cases with paired ESCC and normal tissues through polymerase chain reaction (PCR) and West-ern blot. Results: The expression of Erbin protein and mRNA in ESCC were significantly higher than those of normal esophageal epithe-lium adjacent to cancer (55.2% vs. 0, P<0.05). The high expression of Erbin in ESCC was closely related to TNM stage (64.9% vs. 47.3%, P=0.002) and lymph node metastasis (65.5% vs. 45.0%, P<0.001). Moreover, the high expression of Erbin in ESCC was closely related to poor prognosis (P<0.05). Conclusions: Erbin expression was increased in ESCC and was closely related to poor patient prognosis, which suggested that Erbin may be an important biomarker for the prognosis of cancer patients.

Objective To investigate the relationship of ELK-3 and epithelial-mesenchymal transition ( EMT) for ex-ploring its possible mechanism .Methods The human hepatocellular carcinoma cells ( HCC) were divided into small interference RNA transfection group and Ras-ELK-3 pathway inhibitor group .The protein level of ELK-3 target gene EGR-1 E-cadherin ,vimentin and p38 in HCC were determined by Western blot analysis .Results The protein level of ELK-3 and its target gene EGR-1 in treated human hepatocellular carcinoma cells significantly decreased as compared with the negative control group (P<0.01).The protein level of E-cadherin was significantly increased (P<0.01), while vimentin and p38 were decreased in HCC cells with ELK-3 interference (P<0.01).Conclusions ELK-3 in-terference can inhibit the epithelial-mesenchymal transition of HCC cells by down-regulating p38.
