Non-alcoholic fatty liver disease （NAFLD） is a chronic liver disease closely related to metabolism， which is mainly characterized by abnormal lipid deposition in hepatocytes. In recent years， with the increasing prevalence of obesity and metabolic syndrome， NAFLD has become one of the most common chronic diseases in the world. The pathogenesis of NAFLD is complex and varied， involving the cross-regulation of multiple signaling pathways such as glucose-lipid metabolism， oxidative stress， and inflammation. The TLR4 signaling pathway plays a key role in the development and progression of NAFLD， and abnormal activation of this pathway accelerates the deterioration of NAFLD by promoting the release of pro-inflammatory cytokines， inducing oxidative stress， and exacerbating insulin resistance. Studies have shown that traditional Chinese medicine （TCM） can regulate the TLR4 signaling pathway to alleviate the symptoms and pathological features of NAFLD. The present review summarizes the experimental research progress in the TCM regulation of the TLR4 signaling pathway in treating NAFLD in the past 5 years， covering a wide range of TCM active ingredients （such as polysaccharides， terpenoids， alkaloids， flavonoids） and compound prescriptions. The active ingredients and compound prescriptions of TCM can effectively ameliorate lipid metabolism disorders， reduce insulin resistance， regulate intestinal flora， and inhibit inflammation and oxidative stress by regulating the TLR4 signaling pathway via multiple targets and pathways， thus slowing down the progression of NAFLD. Through in-depth analysis of the pathological mechanisms of NAFLD and exploration of the potential of TLR4 signaling pathway as a therapeutic target， we can provide theoretical support for the application of TCM in the treatment of NAFLD， as well as new perspectives and directions for future clinical research and new drug development， thereby promoting the innovation and development of therapeutic strategies for NAFLD.

OBJECTIVE: To explore the therapeutic effects and underlying mechanisms of Dendrobium officinale (Tiepi Shihu) extract (DOE) on insomnia. METHODS: Forty-two male Sprague-Dawley rats were randomly divided into 6 groups (n=7 per group): normal control, model control, melatonin (MT, 40 mg/kg), and 3-dose DOE (0.25, 0.50, and 1.00 g/kg) groups. Rats were raised in a strong-light (10,000 LUX) and -noise (>80 db) environment (12 h/d) for 16 weeks to induce insomnia, and from week 10 to week 16, MT and DOE were correspondingly administered to rats. The behavior tests including sodium pentobarbital-induced sleep experiment, sucrose preference test, and autonomous activity test were used to evaluate changes in sleep and emotions of rats. The metabolic-related indicators such as blood pressure, blood viscosity, blood glucose, and uric acid in rats were measured. The pathological changes in the cornu ammonis 1 (CA1) region of rat brain were evaluated using hematoxylin and eosin staining and Nissl staining. Additionally, the sleep-related factors gamma-aminobutyric acid (GABA), glutamate (GA), 5-hydroxytryptamine (5-HT), and interleukin-6 (IL-6) were measured using enzyme linked immunosorbent assay. Finally, we screened potential sleep-improving receptors of DOE using polymerase chain reaction (PCR) array and validated the results with quantitative PCR and immunohistochemistry. RESULTS: DOE significantly improved rats' sleep and mood, increased the sodium pentobarbital-induced sleep time and sucrose preference index, and reduced autonomic activity times (P<0.05 or P<0.01). DOE also had a good effect on metabolic abnormalities, significantly reducing triglyceride, blood glucose, blood pressure, and blood viscosity indicators (P<0.05 or P<0.01). DOE significantly increased the GABA content in hippocampus and reduced the GA/GABA ratio and IL-6 level (P<0.05 or P<0.01). In addition, DOE improved the pathological changes such as the disorder of cell arrangement in the hippocampus and the decrease of Nissel bodies. Seven differential genes were screened by PCR array, and the GABA_A receptors (Gabra5, Gabra6, Gabrq) were selected for verification. The results showed that DOE could up-regulate their expressions (P<0.05 or P<0.01). CONCLUSION DOE demonstrated remarkable potential for improving insomnia, which may be through regulating GABA_A receptors expressions and GA/GABA ratio.

At present,in medical academic circle there is no consensus on the optimal diameter of the stent used in transjugular intrahepatic portosystemic shunt(TIPS).In 2021,the Advancing Liver Therapeutic Approaches Consortium(ALTAC)recommended the use of controllable diameter TIPS covered stent system in the performance of TIPS,the stent diameter of this system can be adjusted within the range of 8 mm to 10 mm,and its stability can be maintained for a long time.This system carries several advantages such as accurately regulating portal venous pressure gradient(PPG),optimizing hemodynamic target,protecting liver blood perfusion,reducing shunt-related complications,etc.,indicating that this system has a promising clinical application prospect.Through reviewing the relevant literature,this paper summarizes the research progress of controllable diameter TIPS covered stent system,aiming to better help clinicians engaged in related fields to gain a further understanding of this new technology.

Objective:To investigate the therapeutic effect of exosomes derived from remote ischemic conditioning on neurological dysfunction after cardiopulmonary resuscitation in a rat model of cardiac arrest and the relationship with glycocalyx protection.Methods:Exosomes were isolated from the blood of healthy adult male Sprague-Dawley rats using ultracentrifugation after undergoing remote ischemic conditioning for use as intervention drugs. Nanoparticle tracking analysis technology was used for exosome detection. Thirty-six adult male Sprague-Dawley rats were randomly assigned to 3 groups ( n=12 each) :Sham group, Control group and Exosome group. Cardiac arrest was induced by asphyxia for 7 min in the Control and Exosome groups. Placebo or exosomes (1×10 10 Particles) were infused intravenously at 5 min after the rats had returned of spontaneous circulation. Neuropsychological deficit score (NDS), open field test, Y maze and Morris water maze were used to assess neurological outcomes. The levels of plasma Hyaluronic acid (HA) and syndecan-1 (Sdc-1) were detected by Elisa. The expression levels of matrix metalloproteinase-2/9 (MMP-2/9) in hippocampal CA1 region were detected by Western blot. Results:After undergoing remote ischemic conditioning, the plasma levels of exosomes were elevated in rats compared to normal rats. Compared with the control group, the behavioral experiment of rats in the exosomes group were significantly improved, as evidenced by an increase in horizontal locomotor distance (5.86±2.89 vs. 17.53±5.51, P< 0.05), an increase in the correct rate of spontaneous alternation (13.29±15.07 vs. 42.63±10.25, P< 0.05), and a shortening of avoidance latency (25.83±8.54 vs. 13.49±4.55, P< 0.05). Plasma HA and Sdc-1 levels were significantly lower 24 h after resuscitation (HA: 26.34±9.83 vs. 14.84±6.26, P< 0.05; Sdc-1: 0.05±0.03 vs. 0.02±0.02, P<0.05), along with significantly lower MMP-2/9 levels in hippocampal tissue. Conclusions:Exosomes extracted from the plasma of rats undergoing remote ischemic conditioning can improve neurological dysfunction after cardiac arrest in rats, and the mechanism may be related to the inhibition of metalloproteinases and the reduction of endothelial glycocalyx degradation.

Yigongsan is derived from Xiaoer Yaozheng Zhijue written by QIAN Yi in the Northern Song dynasty， which is the No. 3 formula in the Catalogue of Ancient Famous Classical Formulas（The Second Batch of Pediatrics） released by the National Administration of Traditional Chinese Medicine（TCM） in September 2022， and it can be developed as a class 3.1 new TCM drug. By referring to ancient medical books and modern literature， this study conducted herbal textual research on Yigongsan from five aspects， including historical evolution， origin and processing， dosage conversion， usage and preparation methods， and functional application， then formed the key information table of this formula， in order to provide reference for the development of reference samples and preparations of Yigongsan. Based on the results of the study， it is recommended that Panax ginseng should be removed the basal part of stem（rhizoma）， Poria cocos should be removed the peel， Citrus reticulata should be cut into shreds and Glycyrrhiza uralensis should be used.

Objective Mitochondrial reactive oxygen species(mtROS)could cause damage to pancreatic β-cells,rendering them susceptible to oxidative damage.Hence,investigating the potential of the mitochondria-targeted antioxidant(Mito-TEMPO)to protect pancreatic β-cells from ferroptosis by mitigating lipid peroxidation becomes crucial. Methods MIN6 cells were cultured in vitro with 100 μmol/L sodium palmitate(SP)to simulate diabetes.FerroOrange was utilized for the detection of Fe2+fluorescence staining,BODIPY581/591C11 for lipid reactive oxygen species,and MitoSox-Red for mtROS.Alterations in mitophagy levels were assessed through the co-localization of lysosomal and mitochondrial fluorescence.Western blotting was employed to quantify protein levels of Acsl4,GPX4,FSP1,FE,PINK1,Parkin,TOMM20,P62,and LC3.Subsequently,interventions were implemented using Mito-TEMPO and Carbonyl cyanide 3-chlorophenylhydrazone(CCCP)to observe changes in ferroptosis and mitophagy within MIN6 cells. Results We found that SP induced a dose-dependent increase in Fe2+and lipid ROS in MIN6 cells while decreasing the expression levels of GPX4 and FSP1 proteins.Through bioinformatics analysis,it has been uncovered that mitophagy assumes a crucial role within the ferroptosis pathway associated with diabetes.Additionally,SP decreased the expression of mitophagy-related proteins PINK1 and Parkin,leading to mtROS overproduction.Conversely,Mito-TEMPO effectively eliminated mtROS while activating the mitophagy pathways involving PINK1 and Parkin,thereby reducing the occurrence of ferroptosis in MIN6 cells.CCCP also demonstrated efficacy in reducing ferroptosis in MIN6 cells. Conclusion In summary,Mito-TEMPO proved effective in attenuating mtROS production and initiating mitophagy pathways mediated by PINK1 and Parkin in MIN6 cells.Consequently,this decreased iron overload and lipid peroxidation,ultimately safeguarding the cells from ferroptosis.

This article reported a set of triplets with type V osteogenesis imperfecta (OI) caused by heterozygous variation in the interferon-induced transmembrane protein 5 ( IFITM5) gene. The triplets developed shortness of breath and multiple fractures at 21, 16, and 17 d after birth, respectively. On theadmission, scattered speckled patterns and hard swelling were observed in all three triplets during physical examination; several blisters were found on the right wrist of the second triplet; the smallest triplet had scattered blisters and ulcers in the mouth, complicated by neonatal sepsis, shock, respiratory failure, necrotizing enterocolitis, and intracranial infection. Whole-exome sequencing identified a pathogenic mutation in the triplets, that was located in the 5'-untranslated region of the IFITM5 coding gene, where a base C was converted to T (c.-14C>T). IFITM5 gene of the triplets. IFITM5 gene mutation can result in type V OI, which is inherited in an autosomal dominant pattern. Based on the clinical phenotype caused by the variation in the IFITM5 gene and literature review, the triplets were diagnosed with congenital type V OI. After respiratory support, anti-infection treatment, and symptomatic support treatment, all three triplets were discharged with improved condition. They were followed up to the age of three years and their nutritional status were good. However, their gross motor development was slightly delayed, and they all experienced different degrees and sites of bone fractures again.
