Objective:To explore the long-term therapeutic efficacy and outcomes of liver transplantation for patients with hepatic myelopathy (HM).Methods:Retrospective analysis of 24 adult liver transplantation recipients due to HM at First Central Municipal Hospital from January 2006 to October 2022. HM was extensively classified by the severity of lower extremity symptoms, degree of muscle stiffness, capability for independent ambulation and muscle strength. Furthermore, their long-term outcomes were examined. From January 2000 to October 2022, the databases of China National Knowledge Infrastructure (CNKI) , Google Scholar, PubMed and Web of Science were searched with such keywords as "肝性脊髓病and肝移植" "Hepatic Myelopathy and Liver Transplantation" .Results:After liver transplantation, liver functions and blood ammonia normalized and most clinical symptoms improved. During a follow-up period of (12-190) months, 19 patients showed a lowered grade of HC as compared to pre-transplantation. Four cases achieved a complete recovery of extremity function. No change occurred in severity grade for the remaining 5 patients. However, 4 of them experienced varying degrees of improvement in muscle strength and independent walking capability. This review summarized the clinical characteristics and clinical outcomes of 17 patients from both domestic and international sources. Most of them experiences varying degrees of symptomatic improvements after liver transplantation (16 cases).Conclusions:This study has confirmed the effectiveness of liver transplantation for HM and its contribution to the long-term patient recovery.

Objective To investigate the role of JAK1/STAT3/KHSRP axis in mediating the regulatory effect of LINC00626 on progression of esophagogastric junction adenocarcinoma.Methods We collected surgical tumor and adjacent tissue specimens from 64 patients with esophagogastric junction adenocarcinoma and examined the expression levels of LINC00626 and KHSRP.qRT-PCR was used to detect the expressions of LINC00626 and KHSRP in 6 esophageal adenocarcinoma cell lines(OE-19,TE-7,Bic-1,Flo-1,SK-GT-4,and BE-3)and a normal esophageal epithelial cell line(HET-1A).OE-19 and TE-7 cell lines with stable LINC00626 knockdown and FLO-1 and SK-GT-4 cells stably overexpressing LINC00626 were constructed by lentiviral transfection,and the changes in proliferation,migration and invasion of the cells were evaluated using Cell Counting Kit-8(CCK-8)assay and Transwell migration/invasion assay.The expressions of KHSRP and JAK/STAT pathway proteins in the transfected cells were detected with Western blotting.The effects of LINC006266 knockdown and overexpression on subcutaneous tumor formation and lung metastasis of OE-19 and FLO-1 cell xenografts were tested in nude mice.Results The expression levels of LINC00626 and KHSRP were significantly increased in esophagogastric junction adenocarcinoma tissues and in esophageal adenocarcinoma cells.LINC00626 knockdown obviously inhibited the proliferation,migration and invasion of esophageal adenocarcinoma cells in vitro and decreased their tumor formation and lung metastasis abilities in nude mice,while overexpression of LINC00626 produced the opposite effects.In esophageal adenocarcinoma cells,LINC0626 knockdown significantly decreased and LINC00626 overexpression strongly enhanced the phosphorylation of JAK1 and STAT3.Conclusion High LINC00626 expression promotes esophageal-gastric junction adenocarcinoma metastasis by activating the JAK1/STAT3/KHSRP signal axis.

Objective To investigate the regulatory effect of KHSRP on progression of gastric adenocarcinoma and the role of the JAK1/STAT3 signaling axis in mediating its effect.Methods KHSRP mRNA expression level was detected using qRT-PCR in 120 pairs of gastric adenocarcinoma and adjacent tissues,4 gastric adenocarcinoma cell lines(MKN-28,HGC-27,CRL-5822,and SNU-1)and normal human gastric mucosal GES-1 cells.In HGC-27 cells with KHSRP knockdown and SNU-1 cells with KHSRP overexpression,cell proliferation,migration,invasion and expression levels of JAK/STAT were evaluated using CCK-8 assay,Transwell migration and invasion assays,and Western blotting.In BALB/c-nude mice,HGC-27 cells with KHSRP knockdown and SNU-1 cells overexpressing KHSRP were injected either subcutaneous or via the tail vein to observe subcutaneous xenograft growth and lung metastasis of the tumor cells.Results Gastric adenocarcinoma tissues and cell lines all showed significantly increased KHSRP expression as compared with the adjacent tissues and GES-1 cells.In HGC-27 cells,KHSRP knockdown significantly inhibited cell proliferation,migration and invasion,while KHSRP overexpression enhanced the malignant behaviors of SNU-1 cells.In nude mice,inoculation of HGC-27 cells with KHSRP knockdown resulted in smaller tumor volume and weight,slower cell proliferation rate and fewer lung metastatic foci,and KHSRP-overexpressing SNU-1 cells produced the opposite results.KHSRP knockdown in HGC-27 cells significantly down-regulated the expression levels of JAK1 and STAT3,which were obviously increased in KHSRP-overexpressing SNU-1 cells.Conclusion High expressions of KHSRP promote progression and metastasis of gastric adenocarcinoma possibly by regulating the JAK1/STAT3 signaling axis.

Objective We aimed to establish the benchmark characteristic map of Fuzi decoction and the determination method of multi-index components,and to clarify the key quality attributes of Fuzi decoction.Methods Fifteen batches of Fuzi decoction substance benchmarks samples were prepared;the high-performance liquid chromatography(HPLC)characteristic spectrum of Fuzi decoction was established;and characteristic peak attribution and similarity analysis were performed.Ginsenosides Rg1,Re,Rf,and Rb1 were used as the index components to establish a method to determine ginseng content in Fuzi decoction.The value range of each quality control index was set at a limit of 70%-130%of the average value,and the quantity transfer analysis was performed on the material basis of 15 Fuzi decoction batches.Results The characteristic spectra of the 15 Fuzi decoction batches had 12 common peaks,and seven characteristic peaks of gallic acid,catechin,paeoniflorin,ginsenosides Rg1,Re,and Rb1,and atractylenolide Ⅲ were identified,with a similarity of more than 0.98.Ginsenosides Rg1,Re,Rf,and Rb1 content ranges were 0.51-0.94,0.34-0.62,0.14-0.27,and 0.41-0.76 mg/g,respectively.The transfer rates of ginsenosides Rg1 and Re,Rf,and Rb1 were 12.05%-26.91%,11.15%-43.71%,and 10.53%-33.23%,respectively.Conclusion The characteristic HPLC of Fuzi decoction and the determination method of Fuzi decoction ginseng content established in this study are accurate,reproducible,and stable,laying the foundation for the quality evaluation of the key chemical properties of Fuzi decoction and its preparation.

Cardiovascular diseases are now the leading cause of serious harms to human health,have drawn widespread attention both domestically and internationally. But the current research on mechanism of cardiovascular diseases is not keeping up with the current status of their treatment. The microbiota in the gut,the largest microecological system in the human body and its interaction with the human host have been implicated in a variety of diseases. The relationship between gut microbiota and cardiovascular diseases has been increasingly understood in recent years. The changes of gut microbiota and its metabolites are the major contributing factor for the occurrence and development of cardiovascular diseases,therefore,correction of gut microbiota dysbiosis may provide a novel therapeutic alternative for cardiovascular diseases. This article reviews the role of gut microbiota and its metabolites in cardiovascular diseases,aiming to provide reference for future related studies.

Objective:To explore the causal association of glucose-lipid metabolism and obesity indicators with myocardial infarction by a two-sample Mendelian randomization analysis.Methods:Single nucleotide polymorphisms (SNPs) related to phenotypes were obtained from genome-wide association study databases. The body mass index (BMI) and glycated hemoglobin dataset includes 99 998 samples and 8 126 035 SNPs; the waist-to-hip ratio dataset includes 224 459 samples and 2 562 516 SNPs; the waist circumference and hip circumference dataset includes 462 166 samples and 9 851 867 SNPs; the fasting glucose dataset includes approximately 12 million SNPs; the low-density lipoprotein cholesterol (LDL-C) dataset includes 201 678 samples and 12 321 875 SNPs; the high-density lipoprotein cholesterol (HDL-C), and triglycerides dataset includes 156 109 samples and 15 784 414 SNPs; and the body fat percentage, whole-body fat mass, trunk fat percentage, and trunk fat mass dataset includes 454 588 samples and 9 851 867 SNPs. This study primarily used inverse-variance weighted method to analyze the associations between various exposure factors and outcomes. Heterogeneity among SNPs was assessed using Cochran′s Q test, and horizontal pleiotropy of SNPs was examined using the MR-Egger method. Additionally, a multivariable MR approach was used to adjust for BMI, further validating associations between exposure factors and the risk of myocardial infarction. Results:Higher BMI ( OR=1.070, 95% CI: 1.041-1.100), waist-to-hip ratio ( OR=1.366, 95% CI: 1.113-1.677), LDL-C ( OR=1.638, 95% CI: 1.488-1.803), triglycerides ( OR=1.445, 95% CI: 1.300-1.606), waist circumference ( OR=1.841, 95% CI: 1.650-2.055), hip circumference ( OR=1.247, 95% CI: 1.132-1.372), body fat percentage ( OR=1.795, 95% CI: 1.568-2.055), whole-body fat mass ( OR=1.519, 95% CI: 1.381-1.670), trunk fat percentage ( OR=1.538, 95% CI: 1.374-1.723), and trunk fat mass ( OR=1.421, 95% CI: 1.294-1.561), as well as lower HDL-C ( OR=0.799, 95% CI: 0.729-0.875), have causal effects on myocardial infarction (all P<0.05). After adjusting for BMI, hip circumference, trunk fat percentage, and trunk fat mass were no longer associated with myocardial infarction. However, waist-to-hip ratio ( OR=1.457, 95% CI: 1.132-1.877), fasting glucose ( OR=1.191, 95% CI: 1.024-1.383), glycated hemoglobin ( OR=1.129, 95% CI: 1.034-1.233), LDL-C ( OR=1.592, 95% CI: 1.314-1.929), triglycerides ( OR=1.410, 95% CI: 1.279-1.553), waist circumference ( OR=1.922, 95% CI: 1.448-2.551), body fat percentage ( OR=1.421, 95% CI: 1.072-1.884), and whole-body fat mass ( OR=1.295, 95% CI: 1.031-1.626) remained positively associated with myocardial infarction, while HDL-C ( OR=0.809, 95% CI: 0.729-0.897) remained negatively associated. Conclusions:Abdominal obesity and dysregulation of glucose-lipid metabolism are risk factors for myocardial infarction. Screening for glucose-lipid metabolism (fasting glucose, HDL-C, LDL-C, triglycerides) and obesity-related indicators (waist circumference, waist-to-hip ratio, body fat percentage, and whole-body fat mass) is of great importance for the primary prevention of myocardial infarction.
