Hepatic encephalopathy (HE) is a common complication of severe liver disease in the end stage, and it is urgently needed to improve the rate of effective treatment and clarify the pathogenesis of HE. The liver is a crucial hub for immune regulation, and disruption of immune homeostasis is a key factor in the pathological mechanisms of HE. As the main metabolites of intestinal flora, short-chain fatty acids (SCFAs) play a vital role in the biological processes of both innate and adaptive immunity and can regulate the proliferation and differentiation of immune cells maintain the homeostasis of intestinal microenvironment and the integrity of barrier function. Studies have shown that SCFAs participate in bidirectional and dynamic interactions with the liver-gut-brain axis through immunomodulatory pathways, thereby playing an important role in the diagnosis, treatment, and prognostic evaluation of HE. Starting from the immunoregulatory effect of SCFAs, this article summarizes and analyzes the crosstalk relationship between SCFAs and the liver-gut-brain axis and the significance of SCFAs in the diagnosis and treatment of HE, in order to provide new ideas for optimizing clinical prevention and treatment strategies.

Nuclear factor-kappa B (NF-κB) is an important intracellular transcription factor widely involved in the processes such as immune response, inflammatory response, cell proliferation, and apoptosis. The abnormal activation of the NF-κB signaling pathway plays a pivotal role in various liver diseases including chronic hepatitis, liver fibrosis, liver cirrhosis, and hepatocellular carcinoma. Extensive studies have shown that inhibiting NF-κB activity may effectively reduce inflammation and fibrosis and improve metabolic disorders. Several natural compounds, such as matrine and salvianolic acid B, have shown the potential in suppressing NF-κB activity, thereby exerting anti-inflammatory, anti-fibrotic, and anti-tumor effects. This article systematically reviews the critical role of the NF-κB signaling pathway in liver diseases and its potential as a therapeutic target, in order to highlight its potential as a therapeutic target for liver diseases and provide new directions for the treatment of liver diseases.

Objective:To retrospectively summarize the clinical characteristics and treatment of 49 patients with hyperthyroid cardiopath and to explore the diagnosis and treatment methods of hyperthyroid cardiopathy.Methods:A total of 49 patients with hyperthyroid cardiopath(HC group) who were successfully treated and followed up in the Department of Endocrinology, Shanghai General Hospital, Shanghai Jiao Tong University School of Medicine, from January 2016 to December 2021 were collected, and 85 cases of Graves′ disease without heart disease were collected as the control group(GD group). The medical history, laboratory tests, and echocardiographic parameters of the two groups were compared. Differences in thyroid and cardiac indicators before and after treatment in the HC group were summarized, along with the dosage of β-receptor blockers used in treating different types of conditions(atrial fibrillation and heart failure.Results:Patients in the HC group were older and had a longer duration of hyperthyroidism than those in the GD group( P<0.001, P=0.002). There were no significant differences in thyroid hormone levels between the two groups except for reverse triiodothyronine(rT 3). Age and rT 3 were independent risk factors of hyperthyroid cardiopathy. rT 3 level was linearly positively correlated with brain natriuretic peptide, systolic pulmonary artery pressure, left artrium diamete (LAD) and left ventricular end-systolic diameter(LVDs; r=0.352, P<0.001; r=0.392, P=0.019; r=0.202, P=0.029; r=0.242, P=0.028). In patients of HC group, free triiodothyronine(FT 3) level returned to normal range after 2.87(1.63, 5.53) months of treatment with radioiodine(41/49) or antithyroid drugs(8/49), while brain natriuretic peptide, LAD, LVDs, and systolic pulmonary artery pressure declined after 5.00(1.25, 8.00) months of treatment. Non-selective β-receptor blockers were used for both hyperthyroid heart failure and atrial fibrillation, and there was no statistically significant difference in dosage[(86.52±47.83)mg vs(88.67±47.19)mg, P>0.05]. Conclusions:rT 3 may be a biomarker of hyperthyroid cardiopath and indicate the severity of hyperthyroidism. β-receptor blockers are crucial in treating patients with hyperthyroidism who develop atrial fibrillation and heart failure.

Objective:The effect of three-dimensional(3D)printed bone-attached guide plate assisted cannulated screw fixation of pelvic fracture is reliable,but extensive soft tissue dissection is still required when installing the guide plate.This study aims to compare the efficacy of posterior pelvic ring fracture fixation with iliosacral screw insertion between the assistance of modified percutaneous patient specific 3D printed guide template and conventional fluoroscopy. Methods:From May,2019 and September 2021,28 patients sustained posterior pelvic ring fractures were randomized into 2 groups:A guide template group,in which the iliosacral screw was inserted for fixation of the posterior pelvic ring fracture with the assistance of modified percutaneous patient specific 3D printed guide template,and a fluoroscopy group,in which the iliosacral screw was inserted under the guidance of conventional fluoroscopy.The operation time,fluoroscopic frequency,intraoperative blood loss,and incision length were recorded for each screw insertion.Fracture reduction was evaluated according to the Matta criteria.The screw position was evaluated according to the modified Gras classification,and the functional outcome was evaluated according to Majeed score.The parameters of both groups were compared,and statistical analysis was performed. Results:All the 28 patients were followed up for 12-24 months.Of them,15 iliosacral screws were inserted in 14 patients in the guide template group,and 14 iliosacral screws were inserted in 14 patients in the fluoroscopy group.The operation time,fluoroscopic frequency,screw deviation,incision length,and blood loss in the guide template group were 20-30(25.8±2.8)min,9-15(12.2±1.9),2-4(2.6±0.7)mm,4-5(4.6±0.5)cm,and 5-10(7.8±1.7)mL,respectively,whereas those in the fluoroscopy group were 30-60(48.1±7.5)min,40-96(64.7±16.3),3-6(4.2±0.9)mm,0.8-1.2(1.0±0.1)cm,and 2-5(3.1±1.3)mL,respectively,and there were statistical significance(all P<0.001).Fracture reduction was evaluated according to the Matta criteria,and all the patients reached excellence and good(P=0.584)in the 2 groups.According to modified Gras classification,there were 12 Grade Ⅰ screws,3 Grade Ⅱ screws,and 0 Grade Ⅲ screws in the guide template group,and 10 Grade Ⅰ screws,3 Grade Ⅱ screws,and 1 Grade Ⅲ screw in the fluoroscopy group,with no statistical significance(P=0.334).The functional outcome was evaluated according to Majeed score at the last follow-up,without significant difference between the guide template group and the fluoroscopy group(P=0.908). Conclusion:Compared with the conventional fluoroscopy,it would cost less operation time,less fluoroscopic frequency and increase more accurate screw insertion to fixate the posterior pelvic ring fracture with the assistance of modified percutaneous patient specific 3D printed guide template.

Objective To investigate the expression of miR-372 in the plasma of patients with acute my-eloid leukemia(AML)and the possible mechanism to participate in the development of AML. Methods Real-time quantitative PCR was used to detect the level of miR-372 in plasma. Bioinformatics software predicted the pos-sible target genes of miR-372 and dual luciferase reporter assay was performed to validate the prediction. In HL-60 cells,miR-372 was knocked down,and the effects on cell migration and cloning were detected by scratch test and clone formation. Results The level of miR-372 was significantly up-regulated in the plasma of AML patients. ROC analysis showed that miR-372 could distinguish between AML patients and healthy controls. Dual luciferase report-er assay showed that miR-372 could inhibit the activity of PTEN-3'UTR. Inhibition of miR-372 in HL-60 cells can significantly reduce the cell migration rate and clone formation ability. Conclusion In summary,for the first time,we showed novel data that the level of miR-372 was increased in the plasma of AML patients. By targeting the tumor suppressor gene PTEN,miR-372 may become a potential noninvasive biomarker for the screening and di-agnosis of AML.
