In recent years, growing evidence indicates that the nervous system plays an indispensable role in tumor development and metastasis. Elucidating crosstalk between the nervous system and tumor progression has thrived as a hot topic and a new direction for understanding cancer pathogenesis. Notably, many novel discoveries have suggested that neurotransmitter receptors (NRs) are not only widely expressed in cancer cells, but also play key roles in regulating cancer initiation and progression by diverse approaches. In this review, we summarized the latest advance in cancer neuroscience, especially emphasizing the important roles of different NRs in cancer development and prevention. The exemplary studies presented herein illustrate the emerging view that NRs are profoundly influential, manifested in tumor growth, apoptosis, angiogenesis, metastasis, resistance to drugs, and participate in the formation of neural-cancer interactions. In addition, NRs also regulate cellular metabolic processes and tumor microenvironment (TME) remodeling. More importantly, numerous basic and clinical studies have suggested that NRs may be potential targets for cancer treatments, and corresponding agonists or antagonists have been identified effectively in controlling tumor growth and metastasis. In conclusion, NRs are emerging as novel targets for anti-cancer drug exploration and clinical cancer treatments, while trying to uncover deeper mechanisms and connections between NRs and cancer is of high clinical significance and translational value.

Objective To investigate the effect of sodium-glucose cotransporter 2 inhibitor (empagliflozin, EMPA) on myocardial remodeling in a mouse uremic cardiomyopathy (UCM) model induced by 5/6 nephrectomy, through the phosphatidylinositol 3 kinase (PI3K)/protein kinase B (PKB/AKT)/p65 signaling pathway. Methods The animals were divided into three groups: Sham group (n=6), UCM group (n=8), and UCM+EMPA group (n=8). A UCM model was established in C57BL/6N mice using the 5/6 nephrectomy. Starting from 5 weeks post-surgery, EMPA or a placebo was administered. After 16 weeks, blood pressure, serum creatinine, blood urea nitrogen, 24-hour urine glucose and urine sodium were measured. Cardiac structure and function were assessed by echocardiography. Hematoxylin-eosin (HE) staining and Masson trichrome staining were used to observe pathological changes in the heart and kidneys. Wheat germ agglutinin (WGA) staining was used to evaluate myocardial hypertrophy. The real-time quantitative PCR (RT-qPCR) was used to detect the expression levels of myocardial hypertrophy- and fibrosis-related mRNAs. Western blotting was used to detect the expression levels of PI3K, AKT and p65 in myocardial tissues. Results After 16 weeks, UCM group exhibited significantly higher blood pressure, serum creatinine, blood urea nitrogen than sham group (P<0.01); UCM+EMPA group exhibited lower blood pressure, serum creatinine, blood urea nitrogen, and higher 24 h urine sodium and glucose than UCM group (P<0.05). Echocardiographic results showed ventricular remodeling in the UCM group, evidenced by left ventricular wall thickening, left ventricular enlargement, increased left ventricular mass, and decreased systolic function (P<0.05); ventricular remodeling was alleviated (P<0.05), though there was no significant improvement in systolic function in UCM+EMPA group. HE and Masson stainings revealed myocardial degeneration, necrosis, and interstitial fibrosis in UCM group (P<0.01); the myocardial pathology improved with reduced collagen deposition in UCM+EMPA group (P<0.01). WGA staining confirmed myocardial hypertrophy in UCM group (P<0.01), while myocardial hypertrophy was alleviated in UCM+EMPA group (P<0.01). RT-qPCR results showed myocardial hypertrophy- and fibrosis-related genes (NPPA, NPPB, MYH7, COL1A1, COL3A1, TGF-β1) were upregulated in UCM group (P<0.05), but downregulated in UCM+EMPA group. Western blotting showed PI3K, p-AKT/AKT ratio, and p-p65/p65 ratio were increased in UCM group, but decreased in UCM+EMPA group (P<0.05). Conclusion EMPA can improve myocardial hypertrophy and fibrosis in the UCM mouse model, and it may play the role through inhibiting the PI3K/AKT/p65 signaling pathway.

Fibrosis is a pathological process characterized by an increase in connective tissue and a decrease in parenchymal cells within organ tissues.During its progression,fibrosis can lead to structural damage and functional decline of the affected organ.In recent years,it has found that non-selective cation channel transient receptor potential vanilloid subfamily 1(TRPV1)channel is closely related to fibrosis.When this channel is activated,it can increase the intracellular cation concentration and cause corresponding physiological and pathological changes,playing a particularly crucial role in regulating tissue fibrosis.Animal models have become important tools in studies into the mechanism by which the TRPV1 channel induces organ fibrosis.This article reviews the role of TRPV1 channels in the fibrosis of organs such as the heart,kidney,and pancreas in mice.The relevant signaling pathways in which TRPV1 channels participate to regulate fibrosis are summarized to provide new ideas for studying the pathogenesis of fibrosis and the development of targeted drugs.

Objective To evaluate the impact of optimizing the stroke green channel on the efficiency of acute ischemic stroke management in a county hospital. Methods A retrospective analysis of the emergency stroke green channel treatment data from Sixian People’s Hospital from May 2020 to April 2021 (before optimization of the green channel) and from May 2021 to April 2022 (after optimization of the green channel) was conducted. The rates of intravenous thrombolysis (IVT) and mechanical thrombectomy (MT) patients, as well as door-to-needle time (DNT), door-to-puncture time (DPT), and the modified Rankin scale (mRS) scores of patients three months post-treatment before and after the optimization of the stroke green channel were compared. Results Within one year before and after optimization of the green channel, the number of acute visits for ischemic stroke was 3 143 and 2 623, respectively. Before optimization, 84 and 51 underwent IVT and MT, respectively. After optimization of the green channel, the ratios of patients underwent IVT (n=215) and MT (n=103) significantly increased, and both DNT and DPT were significantly shortened (P<0.000 1); the proportion of MT patients with an mRS score of 0-2 at 3 months post-discharge significantly increased (46/99 vs 13/46, P=0.038). Conclusion After optimizing the green channel at Sixian People’s Hospital, the efficiency of stroke treatment has significantly improved, and the patients’ prognosis improved.
