Abstract
Medical diagnosis heavily relies on the use of bio-imaging techniques. One such technique is the use of ICG-based biological sensors for fluorescence imaging. In this study, we aimed to improve the fluorescence signals of ICG-based biological sensors by incorporating liposome-modified ICG. The results from dynamic light scattering and transmission electron microscopy showed that MLM-ICG was successfully fabricated with a liposome diameter of 100-300 nm. Fluorescence spectroscopy showed that MLM-ICG had the best properties among the three samples (Blank ICG, LM-ICG, and MLM-ICG), as samples immersed in MLM-ICG solution achieved the highest fluorescence intensity. The NIR camera imaging also showed a similar result. For the rat model, the best period for fluorescence tests was between 10 min and 4 h, where most organs reached their maximum fluorescence intensity except for the liver, which continued to rise. After 24 h, ICG was excreted from the rat's body. The study also analyzed the spectra properties of different rat organs, including peak intensity, peak wavelength, and FWHM. In conclusion, the use of liposome-modified ICG provides a safe and optimized optical agent, which is more stable and efficient than non-modified ICG. Incorporating liposome-modified ICG in fluorescence spectroscopy could be an effective way to develop novel biosensors for disease diagnosis.

Abstract
OBJECTIVE Acupuncture can improve the symptoms of alcohol-induced bodily injury and has been accepted by the World Health Organization. In this study, in vivo fluorescence imaging (IVFI) was applied to display and evaluate the effect of electroacupuncture (EA) on liver function (LF) in mice with chronic alcoholic liver injury (cALI). METHODS IVFI of the Cy5.5-galactosylated polylysine (Cy5.5-GP) probe targeting the liver asialoglycoprotein receptor (ASGPR) and liver indocyanine green (ICG) clearance was performed to visually evaluate the effect of EA at ST36 and BL18 on liver reserve function and hepatic metabolism in mice with cALI. In addition, changes in ASGPR expression, serum indexes of LF, and hepatic morphology were observed. RESULTS After EA at ST36 and BL18, the ASGPR-targeted fluorescence signals (FS) in the liver increased significantly in cALI mice (p < 0.05) and exhibited relationships with liver ASGPR expression, liver ICG clearance, liver histology, and serum marker levels of LF in cALI mice undergoing EA intervention. CONCLUSIONS As displayed by IVFI, EA at ST36 and BL18 appears to improve liver reserve function and inhibit the development of liver injury in mice with cALI. EA may have potential as a treatment strategy to protect against ALI.

Abstract
Acute myocardial infarction (AMI) is the most severe form of coronary heart disease caused by ischemia and hypoxia. The study is aimed at investigating the role of neuropeptides and the mechanism of electroacupuncture (EA) in acute myocardial infarction (AMI) treatment. Compared with the normal population, a significant increase in substance P (SP) was observed in the serum of patients with AMI. PGI2 expression was increased in the SP-treated AMI mouse model, and TXA2 expression was decreased. And PI3K pathway-related genes, including Pik3ca, Akt, and Mtor, were upregulated in myocardial tissue of SP-treated AMI patients. Human cardiomyocyte cell lines (HCM) treated with SP increased mRNA and protein expression of PI3K pathway-related genes (Pik3ca, Pik3cb, Akt, and Mtor). Compared to MI control and EA-treated MI rat models, Myd88, MTOR, Akt1, Sp, and Irak1 were differentially expressed, consistent with in vivo and in vitro studies. EA treatment significantly enriched PI3K/AKT signaling pathway genes within MI-associated differentially expressed genes (DEGs) according to Kyoto Encyclopedia of Genes and Genomes (KEGG). Furthermore, it was confirmed by molecular docking analysis that PIK3CA, AKT1, and mTOR form stable dockings with neuropeptide SP. PI3K/AKT pathway activity may be affected directly or indirectly by EA via SP, which corrects the PGI2/TXA2 metabolic imbalance in AMI. MI treatment is now better understood as a result of this finding.

Abstract
The hypoxic nature of tumours limits the efficiency of oxygen-dependent photodynamic therapy (PDT). Hence, in this study, indocyanine green (ICG)-loaded lipid-coated zinc peroxide (ZnO2) nanoparticles (ZnO2@Lip-ICG) was constructed to realize tumour microenvironment (TME)-responsive self-oxygen supply. Near infrared light irradiation (808 nm), the lipid outer layer of ICG acquires sufficient energy to produce heat, thereby elevating the localised temperature, which results in accelerated ZnO2 release and apoptosis of tumour cells. The ZnO2 rapidly generates O2 in the TME (pH 6.5), which alleviates tumour hypoxia and then enhances the PDT effect of ICG. These results demonstrate that ZnO2@Lip-ICG NPs display good oxygen self-supported properties and outstanding PDT/PTT characteristics, and thus, achieve good tumour proliferation suppression.

Influence of Acupuncture on Microcirculation Perfusion of Pericardium Meridian and Heart in Acute Myocardial Ischemia Model Rats. Chin J Integr Med 2021; 28:69-75. [PMID: 34816366 DOI: 10.1007/s11655-021-3294-9] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 08/12/2020] [Indexed: 10/19/2022]
Abstract
OBJECTIVE To observe the influence of acupuncture on microcirculation perfusion of the pericardium meridian and heart in acute myocardial ischemia (AMI) rats and evaluate whether acupuncture can simultaneously affect the meridians and corresponding viscera. Additionally, acupoints at different meridians were compared and whether they exert the same effects was discussed. METHODS Totally 32 Sprague-Dawley rats were subjected to left anterior descending (LAD) ligation to develop an AMI model. Rats were divided into 4 groups, including AMI, acupuncture Neiguan (PC 6), Lieque (LU 7) and Qiansanli (LI 10) groups (n=8). Eight rats received only thoracotomy (sham-operated group). The rats in the acupuncture groups received manual acupuncture at PC 6, LU 7 and LI 10 acupoints for 15 min, respectively. The microcirculation perfusion of pericardium meridian and heart was monitored by laser speckle perfusion imager (LSPI) before, during and after acupuncture manipulation for 15 min. Subsequently, the perfusion unit (PU) was calculated and analyzed by PSI System. RESULTS After LAD, compared to pre-acupuncture stage, the heart microcirculation perfusion (HMP) in the AMI group decreased continuously at during-acupuncture (P>0.05) and post-acupuncture stages (P<0.05), and the pericardium meridian microcirculation perfusion (PMP) showed no significant differences at 3 stages (P>0.05). Compared to pre-acupuncture stage, the PMP and HMP in PC 6 group significantly increased during acupuncture manipulation (both P<0.05), and PMP decreased obviously after acupuncture (P<0.05). The PMP in the LU 7 and LI 10 groups were slightly elevated (both P>0.05); however, they were significantly reduced after acupuncture manipulation (both P<0.05). Additionally, HMP of LI 10 group was decreased significantly during acupuncture, especially compared to pre-acupuncture stage (P<0.05). CONCLUSIONS Acupuncture at PC 6 obviously increased the PMP and HMP in AMI rats, and the effects were superior to at LU 7 and LI 10 acupoints. It was further confirmed that acupuncture promoted qi and blood circulation, indicating that acupoint specificity exists and features a meridian-propagated effect.

Abstract
Visceral pain frequently produces referred pain at somatic sites due to the convergence of somatic and visceral afferents. In skin overlying the referred pain, neurogenic spots characterized by hyperalgesia, tenderness and neurogenic inflammation are found. We investigated whether neurogenic inflammatory spots function as acupoints in the rat model of bile duct ligation-induced liver injury. The majority of neurogenic spots were found in the dorsal trunk overlying the referred pain and matched with locations of acupoints. The spots, as well as acupoints, showed high electrical conductance and enhanced expression of the neuropeptides substance P (SP) and calcitonin gene-related peptide (CGRP). Electroacupuncture at neurogenic spots reduced serum hepatocellular enzyme activities and histological patterns of acute liver injury in bile duct ligation (BDL) rats. The results suggest that the neurogenic spots have therapeutic effects as acupoints on hepatic injury in bile-duct ligated rats.

Abstract
Crocin is the main monomer of saffron, which is a momentous component of traditional Chinese medicine Lang Qing A Ta. Here, we tried to probe into the role of crocin in liver fibrosis. Hematoxylin-eosin staining and Sirius Red staining were used to observe the pathological changes of liver tissues. After hepatic stellate cells (HSCs) were isolated from liver tissues, lnc-LFAR1, MTF-1, GDNF, and α-SMA expressions were detected by qRT-PCR and western blot. Immunohistochemistry and immunofluorescence were used to detect α-SMA expression. Chromatin immunoprecipitation was used to analyze the binding of MTF-1 to the GDNF promoter. Moreover, the dual-luciferase reporter gene, RNA pull-down, and RNA immunoprecipitation were used to clarify the interaction between MTF-1 and GDNF, lnc-LFAR1 and MTF-1. The degree of liver fibrosis was more severe in the mice from the liver fibrosis model, while the liver fibrosis was alleviated by the injection of crocin. lnc-LFAR1, GDNF, and α-SMA were up-regulated, and MTF-1 was down-regulated in liver fibrosis tissues and cells, while these trends were reversed after the injection of crocin. Besides, lnc-LFAR1 negatively regulated MTF-1 expression, and positively regulated GDNF and α-SMA expressions, and MTF-1 was enriched in the promoter region of GDNF. Furthermore, the cellular direct interactions between MTF-1 and GDNF, lnc-LFAR1 and MTF-1 were verified. In vivo experiments confirmed the relief of crocin on liver fibrosis. Our research expounded that crocin restrained the activation of HSCs through the lnc-LFAR1/MTF-1/GDNF axis, thereby ameliorating liver fibrosis.

Abstract
The gut-brain axis is a bidirectional information interaction system between the central nervous system (CNS) and the gastrointestinal tract, in which gut microbiota plays a key role. The gut microbiota forms a complex network with the enteric nervous system, the autonomic nervous system, and the neuroendocrine and neuroimmunity of the CNS, which is called the microbiota-gut-brain axis. Due to the close anatomical and functional interaction of the gut-liver axis, the microbiota-gut-liver-brain axis has attracted increased attention in recent years. The microbiota-gut-liver-brain axis mediates the occurrence and development of many diseases, and it offers a direction for the research of disease treatment. In this review, we mainly discuss the role of the gut microbiota in the irritable bowel syndrome, inflammatory bowel disease, functional dyspepsia, non-alcoholic fatty liver disease, alcoholic liver disease, cirrhosis and hepatic encephalopathy via the gut-liver-brain axis, and the focus is to clarify the potential mechanisms and treatment of digestive diseases based on the further understanding of the microbiota-gut- liver-brain axis.

Prevention of Nonalcoholic Hepatic Steatosis by Shenling Baizhu Powder: Involvement of Adiponectin-Induced Inhibition of Hepatic SREBP-1c. OXIDATIVE MEDICINE AND CELLULAR LONGEVITY 2020; 2020:9701285. [PMID: 33062150 PMCID: PMC7533788 DOI: 10.1155/2020/9701285] [Citation(s) in RCA: 12] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 03/15/2020] [Revised: 05/17/2020] [Accepted: 05/25/2020] [Indexed: 12/30/2022]
Abstract
Background Nonalcoholic fatty liver disease (NAFLD) is a common chronic liver disease worldwide, and its incidence is increasing annually, but there is currently no specific drug for treating NAFLD. Shenling Baizhu powder (SL) is a safe herbal compound commonly used in clinical practice. Our previous research has shown that SL has the effect of preventing NAFLD, but its specific mechanism has not been determined. In this study, the potential mechanism of SL on NAFLD was explored by in vivo experiments. Methods Wistar rats fed a choline-deficient amino acid-defined diet (CDAA) were treated with SL for 8 weeks. Then, serum samples were collected to obtain biochemical indicators; adipose tissue and liver samples were collected for pathological detection; a moorFLPI-2 blood flow imager was used to measure liver microcirculation blood flow, and a rat cytokine array was used to screen potential target proteins. The expression of liver adiponectin/SREBP-1c pathway-related proteins was determined by Western blotting. Results SL effectively reduced the liver wet weight, as well as the levels of total cholesterol (TC) and triglyceride (TG) in the liver, and ameliorated liver injury in CDAA-fed rats. Pathological examinations showed that SL markedly reduced liver lipid droplets and improved liver lipid accumulation. In addition, the detection of liver blood flow showed that SL increased liver microcirculation in CDAA-fed rats. Through the cytokine array, a differentially expressed cytokine, namely, adiponectin, was screened in the liver. Western blotting assays showed that SL increased the expression of adiponectin and phosphoacetyl-CoA Carboxylase (p-ACC) in the liver and decreased the expression of steroid regulatory element-binding protein-1c (SREBP-1c) and fatty acid synthase (FAS). Conclusion These results suggest that SL can increase the levels of adiponectin in the liver and serum and can inhibit the expression of SREBP-1c, thereby regulating systemic lipid metabolism and reducing liver lipid accumulation.

Abstract
Background: Nonalcoholic fatty liver disease (NAFLD) is considered one of the most common and most important conditions affecting the liver, because of its increasing prevalence all over the world. It is usually associated with elevated liver enzymes and ranges from simple steatosis to liver cirrhosis. This study was conducted to compare the effects of electroacupuncture (EA) versus aerobic interval training (AIT) exercise and how they affect liver functions in people suffering from nonalcoholic fatty liver. Methods: This study was carried out on 50 female patients suffering from NAFLD with age ranging from 30 to 55 years; they were randomly divided into two equal groups: group A received (EA) stimulation at points of liver 3 (LR3), liver 14 (LR14), gall bladder 34 (GB34), and stomach 36 (ST36), whereas group B received AIT exercise. All patients in both groups A and B received 3 sessions per week for 6 weeks (receiving noninterrupted 18 sessions) in addition to their standard medications. Evaluation of all patients in both groups A and B was carried out before and after the treatment program by measuring the levels of alanine aminotransferase (ALT), aspartate aminotransferase (AST), triglycerides (TGs), and C-reactive protein (CRP). Results: There is a significant decrease (p < 0.05) of ALT, AST, TGs, and CRP within each group, A and B, after 6 weeks of treatment sessions. A significant difference post-treatment was found between both groups in ALT, AST, and TGs (p < 0.05). However, there was no significant difference in CRP (p > 0.05) between both groups post-treatment. Conclusions: It can be concluded that both EA and AIT exercise are potent modalities that improve liver functions in people with NAFLD with better effect toward EA.

Abstract
The visual evaluation of liver function (LF) has always been a hot topic in research on liver diseases. In vivo fluorescence imaging (IVFI) of the Cy5.5-galactosylated polylysine (Cy5.5-GP) probe targeting asialoglycoprotein receptor (ASGPR), for evaluating LF in chronic alcoholic liver injury (cALI) mice was investigated in this study. The decrease of fluorescence signals in the livers showed a biological relationship with the liver ASGPR expression, histology, and serum marker levels of LF in cALI mice. The targeted IVFI of ASGPR as a novel method can intuitively and noninvasively display the characteristics of liver's ASGPR level to provide a reference for evaluating LF.

Abstract
Although acupuncture therapy is increasingly used to treat diverse symptoms and disorders in humans, its underlying mechanism is not known well. Only recently have experimental studies begun to provide insights into how acupuncture stimulation generates and relates to pathophysiological responsiveness. Acupuncture intervention is frequently used to control pathologic symptoms in several visceral organs, and a growing number of studies using experimental animal models suggest that acupuncture stimulation may be involved in inducing anti-inflammatory responses. The vagus nerve, a principal parasympathetic nerve connecting neurons in the central nervous system to cardiovascular systems and a majority of visceral organs, is known to modulate neuroimmune communication and anti-inflammatory responses in target organs. Here, we review a broad range of experimental studies demonstrating anti-inflammatory effects of electroacupuncture in pathologic animal models of cardiovascular and visceral organs and also ischemic brains. Then, we provide recent progress on the role of autonomic nerve activity in anti-inflammation mediated by electroacupuncture. We also discuss a perspective on the role of sensory signals generated by acupuncture stimulation, which may induce a neural code unique to acupuncture in the central nervous system.
