Abstract
Objective: intrahepatic portocaval shunt (TIPS) in the treatment of hepatic sinusoidal obstruction syndrome (HSOS). Methods: A retrospective analysis was performed on 27 patients with HSOS who were treated with TIPS in our center from July 2018 to July 2020. The changes of portal vein pressure (PVP), portal vein pressure gradient (PPG) and liver function were observed, so as to evaluate the efficacy. Paired t test was adopted to evaluate the quantitative parameters, while χ (2) test was used to analyze qualitative parameters, with P < 0.05 as statistical difference. Results: PVP decreased from (4.41 ± 0.18) kPa before shunt to (2.69 ± 0.11) kPa after shunt (t = 82.41, P < 0.001), PPG decreased from (3.23 ± 0.18) kPa before shunt to (1.46 ± 0.23) kPa after shunt (t = 32.41, P < 0.001). The liver function improved significantly after operation. After 24 months of follow-up, 3 patients developed stent restenosis and recanalized after balloon dilation. Three patients developed hepatic encephalopathy, which was improved after drug treatment. One patient underwent liver transplantation due to liver failure. Conclusion: TIPS is effective in the treatment of HSOS in the short and medium term, and can provide time for liver transplantation patients to wait for liver source.

Abstract
Objective: To verify Baveno VI criteria, Expanded-Baveno VI criteria, liver stiffness×spleen diameter-to-platelet ratio risk score (LSPS), and platelet count/spleen diameter ratio (PSR) in evaluating the severity value of esophageal varices (EV) in patients with non-cirrhotic portal hypertension (NCPH). Methods: 111 cases of NCPH and 204 cases of hepatitis B cirrhosis who met the diagnostic criteria were included in the study. NCPH included 70 cases of idiopathic non-cirrhotic portal hypertension (INCPH) and 41 cases of nontumoral portal vein thrombosis (PVT). According to the severity of EV on endoscopy, they were divided into the low-bleeding-risk group (no/mild EV) and the high-bleeding-risk group (moderate/severe EV). The diagnostic value of Baveno VI and Expanded-Baveno VI criteria was verified to evaluate the value of LSPS and PSR for EV bleeding risk severity in NCPH patients. The t-test or Mann-Whitney U test was used to compare the measurement data between groups. Comparisons between counting data groups were performed using either the χ2 test or the Fisher exact probability method. Results: Considering endoscopy was the gold standard for diagnosis, the missed diagnosis rates of low/high bleeding risk EVs in INCPH/PVT patients with Baveno VI and Expanded-Baveno VI criteria were 50.0%/30.0% and 53.8%/50.0%, respectively. There were no statistically significant differences in platelet count (PLT), spleen diameter, liver stiffness (LSM), LSPS, and PSR between low-bleeding-risk and high-bleeding-risk groups in INCPH patients, and the area under the receiver operating characteristic curve (AUC) of LSPS and PSR was 0.564 and 0.592, respectively (P=0.372 and 0.202, respectively). There were statistically significant differences in PLT, spleen diameter, LSPS, and PSR between the low and high-bleeding risk groups in PVT patients, and the AUCs of LSPS and PSR were 0.796 and 0.833 (P=0.003 and 0.001, respectively). In patients with hepatitis B cirrhosis, the Baveno VI and Expanded-Baveno VI criteria were used to verify the low bleeding risk EV, and the missed diagnosis rates were 0 and 5.4%, respectively. There were statistically significant differences in PLT, spleen diameter, LSM, LSPS and PSR between the low-bleeding-risk and high-bleeding-risk groups (P<0.001). LSPS and PSR AUC were 0.867 and 0.789, respectively (P<0.05). Conclusion: Baveno VI and Expanded-Baveno VI criteria have a high missed diagnosis rate for EVs with low bleeding risk in patients with INPCH and PVT, while LSPS and PSR have certain value in evaluating EV bleeding risk in PVT patients, which requires further clinical research.

Abstract
Introduction Previous studies have demonstrated that exposed to the initial suboptimal intrauterine environment of gestational diabetes mellitus (GDM) may increase risk of cardiovascular disease in adulthood. Methods In order to investigate the underlying mechanisms involved in the increased risk of cardiovascular diseases (CVDs) in the offspring of GDM, we applied a high-throughput proteomics approach to compare the proteomic expression profile of human umbilical vessels of normal and GDM offspring. Results A total of significantly different 100 proteins were identified in umbilical vessels from GDM group compared with normal controls, among which 31 proteins were up-regulated, while 69 proteins were down-regulated. Differentially expressed proteins (DEPs) are validated using Western blotting analysis. The analysis of these differently expressed proteins (DEPs) related diseases and functions results, performed by Ingenuity Pathway Analysis (IPA) software. Based on "Diseases and Disorders" analysis, 17 proteins (ACTA2, ADAR, CBFB, DDAH1, FBN1, FGA, FGB, FGG, GLS, GSTM1, HBB, PGM3, PPP1R13L, S100A8, SLC12A4, TPP2, VCAN) were described to be associated with CVD, especially in Anemia, Thrombus and Myocardial infarction. Functional analysis indicated that DEPs involved in many cardiovascular functions, especially in "vasoconstriction of blood vessel" (related DEPs: ACTA2, DDAH1, FBN1, FGA, FGB, and FGG). Upstream regulator analyses of DEPs identifies STAT3 as inhibitor of ACTA2, FGA, FGB, and FGG. Conclusion The results of this study indicate that intrauterine hyperglycemia is associated with an elevated risk of cardiovascular risk in the offspring.

Abstract
Hepatocellular carcinoma (HCC) is one of the most common malignant tumors worldwide. Microvascular invasion (MVI) is considered the major risk factor for postoperative recurrence and metastasis in HCC. The diagnosis of MVI relies on the postoperative pathological assessment of the tumor tissues. Seeking non-invasive methods and biomarkers for evaluation of MVI before surgery has important clinical implications for guiding surgical treatment and improving patients' survival. Recent studies have reported the applications of radiomics technique in prediction of MVI in HCC and showed promising results. Herein we summarized the research progress in CT- or MRI-based radiomics models for prediction of MVI in HCC to provide helpful thinking for further research in this field.

Abstract
Biliary liver disease refers to intrahepatic and extrahepatic bile duct system lesions or bile duct epithelial cells damage, resulting in abnormal liver function, inflammation and fibrosis, which mainly manifests as chronic cholestatic liver disease. The common causes include primary biliary cholangitis, primary sclerosing cholangitis, progressive familial intrahepatic cholangitis, bile duct complications after liver transplantation, and vanishing bile duct syndrome caused by drugs or serious infections, and the most prominent symptoms affecting the patients quality life is pruritus and jaundice. Endoscopic retrograde duodenoscopic cholangiopancreatography and cholangiopancreatoscopy (SpyGlass) and other endoscopic examinations can significantly improve the accuracy of early differential diagnosis,cytology and biopsy of primary sclerosing cholangitis, immunoglobulin G4-related cholangitis and cholangiocarcinoma. Endoscopic nasobiliary drainage, balloon dilatation and intrabiliary stent implantation can significantly improve pruritus symptoms, liver biochemical indicators and prognosis. Therefore, gastrointestinal endoscopy has important value and application prospects in the diagnosis and treatment of biliary liver diseases.

Abstract
Recurrent pregnancy loss (RPL) is defined as the loss of two or more consecutive pregnancies before the 20 weeks of gestation. Recurrent pregnancy loss affects about 1-2% of couples trying to conceive; however, the mechanisms leading to this complication are largely unknown. Our previous studies using comparative proteomics identified 314 differentially expressed proteins (DEPs) in the placental villous. In this study, we identified 5479 proteins from a total of 34,157 peptides in decidua of patients with early recurrent pregnancy loss (Data are available via ProteomeXchange with identifier PXD023849). Further analysis identified 311 DEPs in the decidua tissue; and 159 proteins were highly expressed while 152 proteins were lowly expressed. These 311 proteins were further analyzed by using Ingenuity Pathway Analysis (IPA). The results suggested that 50 DEPs played important roles in the embryonic development. Upstream analysis of these DEPs revealed that AGT was the most important upstream regulator. Furthermore, protein - protein interaction (PPI) analysis of the embryonic development DEPs from the placental villous and decidua was performed in the STRING database. This study identified several proteins specifically associated with embryonic development in decidua of patients with early recurrent pregnancy loss. Therefore, these results provide new insights into potential biological mechanisms, that may ultimately inform recurrent pregnancy loss.

Abstract
Background Polycystic ovary syndrome (PCOS) is the most common type of endocrine disorder, affecting 5–11% of women of reproductive age worldwide. microRNAs (miRNAs) stably exist in circulating blood encapsulated in extracellular vesicles such as exosomes; therefore, serum miRNAs have the potential to serve as novel PCOS biomarkers. Methods To identify miRNA biomarkers that are associated with PCOS, we performed a comprehensive sequence-based characterization of the PCOS serum miRNA landscape. The serum exosomes were successfully isolated and characterized in a variety of ways. Next, sequence-based analysis was performed on serum exosomes to screen the differentially expressed miRNAs in women with and without PCOS. Results The sequence data revealed that the levels of 54 miRNAs significantly differed between PCOS patients and normal controls. The levels of these miRNAs were detected by RT-qPCR. The results show that hsa-miR-1299, hsa-miR-6818-5p hsa-miR-192-5p, and hsa-miR-145-5p are significantly differentially expressed in PCOS patients serum exosomes and identify these microRNAs as potential biomarkers for PCOS. Furthermore, Gene Ontology (GO) analyses and KEGG pathway analyses of the miRNA targets further allowed to explore the potential implication of the miRNAs in PCOS. Conclusion Our findings suggest that serum exosomal miRNAs serve important roles in PCOS and may be used as novel molecular biomarkers for clinical diagnosis.

Abstract
Portal hypertension-related esophagogastric variceal bleeding (EVB) is deadly. Therefore, multidisciplinary management involving hepatologists, digestive endoscopy, radiological intervention, and/or surgery is necessary. Digestive endoscopy is the core of the multidisciplinary approach to the overall management of portal hypertension. It plays an important role in the early warning, emergency treatment, and the prevention of the initial and re-bleeding of portal hypertension accompanied by esophagogastric varices. In addition, gastroscopy with endoscopic ultrasound scanning can enhance the management capabilities of ectopic varices.

Abstract
Objective: To investigate the methods for qualitative pathological assessment of dynamic changes in liver fibrosis/cirrhosis after antiviral therapy in patients with chronic hepatitis B (CHB), since antiviral therapy can partially reverse liver fibrosis and cirrhosis caused by hepatitis B and semi-quantitative, rather than qualitative, pathological assessment is often used for the research on liver fibrosis regression. Methods: Previously untreated CHB patients with liver fibrosis and cirrhosis were enrolled, and liver biopsy was performed before treatment and at 78 weeks after the antiviral therapy based on entecavir. The follow-up assessment was performed once every half a year. Based on the proportion of different types of fibrous septum, we put forward the new qualitative criteria called P-I-R classification (predominantly progressive, predominantly regressive, and indeterminate) for evaluating dynamic changes in liver fibrosis. This classification or Ishak fibrosis stage was used to evaluate the change in liver fibrosis after treatment and Ishak liver inflammation score was used to evaluate the change in liver inflammation after treatment. Results: A total of 112 CHB patients who underwent liver biopsy before and after treatment were enrolled, and among these patients, 71 with an Ishak stage of ≥3 and qualified results of live biopsy were included in the final analysis. Based on the P-I-R classification, 58% (41/71) were classified as predominantly progressive, 29% (21/71) were classified as indeterminate, and 13% (9/71) were classified as predominantly regressive; there were no significant differences between the three groups in alanine aminotransferase, aspartate aminotransferase, albumin, HBeAg positive rate, HBV DNA, and liver stiffness (P < 0.05). After treatment, the proportion of predominantly progressive, indeterminate, or predominantly regressive patients changed to 11% (8/71), 11% (8/71), and 78% (55/71), respectively. Among the 35 patients who had no change in Ishak stage after treatment, 72% (25/35) were classified as predominantly regressive and had certain reductions in the Laennec score, percentage of collagen area, and liver stiffness. Conclusion: This new P-I-R classification can be used to assess the dynamic changes in liver fibrosis after antiviral therapy in CHB patients.

Abstract
Liver fibrosis and cirrhosis, is a chronic, occult progression that is potentially reversible and complicated. The hepatic venous pressure gradient is a "gold standard" for risk stratification of liver cirrhosis and is superior to pathological examination of liver. This article briefly assesses the invasive and non-invasive measuring methods of the hepatic venous pressure gradient. With the hepatic venous pressure gradient-guided precise treatment for hepatic cirrhosis of portal hypertension, the incidence of clinical endpoints of hepatic portal hypertension can be significantly reduced. Establishing a long-term monitoring and management model similar to "high blood pressure" is a dream for the diagnosis and treatment of future cirrhosis and portal hypertension.

Abstract
Objective: To investigate the clinical features and risk factors for acute kidney injury (AKI) in patients with cirrhosis. Methods: A total of 1 165 hospitalized patients with chronic liver diseases were enrolled. Among them, 94 patients had chronic hepatitis, while 1 071 patients were diagnosed as cirrhosis. The clinical data, renal and liver function were retrospectively analyzed. AKI was determined according to the criteria proposed by International Club of Ascites. Compared with chronic hepatitis group, the clinical features and risk factors for AKI in patients with cirrhosis were evaluated using logistic regression. Results: The prevalence of AKI in chronic hepatitis and cirrhosis were 4.26%(4/94) and 11.11% (119/1 071), respectively. The AKI rates in patients with liver function Child A, B and C were 3.77%(18/377), 10.88% (41/377) and 27.65%(60/217), respectively. The independent risk factors for AKI in cirrhotic patients included infections (OR=5.37, 95%CI 3.24-8.90, P=0.000), acute on chronic liver failure (ACLF, OR=4.55, 95%CI 2.60-7.98, P=0.000) and diabetes (OR=1.70, 95%CI 1.07-2.70, P=0.024). The mortality rate of cirrhotic patients with AKI was 36.97% within 2 months. Moreover, the mortality rates in stage Ⅰ, Ⅱ and Ⅲ AKI were 20.31%, 36.00% and 73.33%, respectively. Conclusions: The mortality rate of cirrhotic patients with stage Ⅲ AKI is extremely high. Infections, ACLF and diabetes are the independent risk factors for AKI in patients with cirrhosis.

Abstract
PURPOSE Damage to the uterosacral ligaments is an important contributor to uterine and vaginal prolapse. The aim of this study is to identify differentially expressed proteins (DEPs) in the uterosacral ligaments of women with and without pelvic organ prolapse (POP) and analyze their relationships to cellular mechanisms involved in the pathogenesis of POP. EXPERIMENTAL DESIGN Uterosacral ligament connective tissue from four patients with POP and four control women undergo iTRAQ analysis followed by ingenuity pathway analysis (IPA) of DEPs. DEPs are validated using Western blot analysis. RESULTS A total of 1789 unique protein sequences are identified in the uterosacral ligament connective tissues. The expression levels of 88 proteins are significantly different between prolapse and control groups (≥1.2-fold, p < 0.05). IPA demonstrates the association of 14 DEPs with "Connective Tissue Function." Among them, fibromodulin, collagen alpha-1 (XIV) chain, calponin-1, tenascin, and galectin-1 appear most likely to play a role in the etiology of POP. CONCLUSIONS AND CLINICAL RELEVANCE At least six proteins not previously associated with the pathogenesis of POP with biologic functions that suggest a plausible relationship to the disorder are identified. These results may be helpful for furthering the understanding of the pathophysiological mechanisms of POP.

Abstract
The activation of renin-angiotensin-aldosterone-vasopressin system is a key factor in the formation of ascites due to splanchnic vasodilation in cirrhosis. In theory, aldosterone antagonists, contraction of blood vessels, vasopressin V2 receptor, and angiotensin receptor antagonists are important targets for the prevention and treatment of cirrhotic ascites. The 15%-20% of patients with cirrhotic ascites that show no response to at least one week's treatment with potent diuretics (spironolactone 160 mg/d combined with furosemide 80 mg/d) are considered to have refractory ascites. At present, effective treatments for refractory ascites include tolvaptan, large-volume paracentesis (4000-6000 ml/time/day) combined with albumin (4 g/L ascites), ascites ultrafiltration and reinfusion, transjugular intrahepatic portosystemic shunt, and liver transplantation. In the future, with the development of vasoactive drugs, rifaximin, ascites drainage pump, and other new therapies, the treatment of refractory ascites may be more effective to reduce the need for liver transplantation.

Abstract
There are two common types of hereditary polycystic kidney diseases, autosomal dominant polycystic kidney disease and autosomal recessive polycystic kidney disease. Congenital hepatic fibrosis is an autosomal recessive disorder and can occur in hereditary polycystic kidney disease. Therefore, hereditary polycystic kidney disease is one of the causes of unexplained liver fibrosis and liver cirrhosis.

Abstract
BACKGROUND The prognosis of patients with hepatocellular carcinoma(HCC) is generally very poor with a 5-year survival rate of less than 15% since most of them are diagnosed clinically at their late stage. However, the differential diagnosis between alpha fetoprotein(AFP) negative HCC and cirrhotic nodules is still difficult. OBJECTIVES To evaluate the diagnostic value of glypican-3(GPC3) in patients with AFP negative hepatitis B related HCC. METHODS The liver tissue GPC3 (GPC3L) expression was tested from 426 for surgery and 179 of needle biopsies of hepatitis B related HCC patients using immunohistochemistry staining. Serum GPC3 (GPC3S) and AFP were also measured. RESULTS Among surgical HCC samples, 80.0% of GPC3L expression was positive, however, in paracarcinomatous and cirrhotic nodules were negative. In needle biopsy tissues, GPC3L positively expression was in 74.9%. The sensitivity of AFP>400 µg/L was 25.4%. The GPC3S >3.5 µg/L was determined as a positive. The area of ROC curve of GPC3S was 0.68(95% CI 0.56-0.79,P<0.05) in all HCC patients,0.81 (95% CI 0.62 -0. 98, P<0.05) in AFP greater or equal to 400 µg/L and 0.64 (95% CI 0.51-0.77, P=0.051) in AFP negative patients. The GPC3S was positive in 48.8% of patients with AFP negative. No difference was observed between GPC3L/GPC3S and serum AFP. CONCLUSIONS GPC3 may be helpful in improving diagnosis of HCC and in differentiating diagnosis between AFP negative HCC and cirrhotic nodules.

Abstract
Ezrin is a member of the ezrin-radixin-moesin (ERM) family of membrane-cytoskeletal linkage proteins. It is important for maintenance of cell shape, adhesion, migration and division. The overexpression of ezrin in some tumours is associated with increased cell migration that is mediated by the Rho/ROCK family of small GTPases. To investigate the role of ezrin in the migration of ectopic endometrial cells in endometriosis, we conducted real-time quantitative RT-PCR analysis of the eutopic and ectopic endometrium from women with endometriosis compared with those without the disease. RNAi, wound healing assays and western blot analysis of endometriotic cells were also included in this research. We found significantly higher levels of mRNA expression of ezrin (0.42 versus 0.27, P < 0.05), RhoA (0.99 versus 0.74, P < 0.05), RhoC (0.79 versus 0.43, P < 0.005) and ROCK1 (0.68 versus 0.38, P < 0.005) in the ectopic endometrial cells compared with the eutopic endometrial cells in endometriosis. Blocking ezrin with small-interfering RNA reduced the migration of ectopic endometrial cells with decreased expression of RhoA (42.68%), RhoC (58.42%) and ROCK1 (59.88%). Our results indicate that the over-expression of ezrin in endometriosis may play a significant role in the migration of endometrial cells of endometriosis, and the RhoC/Rock pathway may provide a promising treatment target.

Reactive oxygen species mediate high glucose-induced heparanase-1 production and heparan sulphate proteoglycan degradation in human and rat endothelial cells: a potential role in the pathogenesis of atherosclerosis. Diabetologia 2011; 54:1527-38. [PMID: 21424539 DOI: 10.1007/s00125-011-2110-z] [Citation(s) in RCA: 43] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/22/2010] [Accepted: 02/01/2011] [Indexed: 01/10/2023]
Abstract
AIMS/HYPOTHESIS The content of heparan sulphate is reduced in the endothelium under hyperglycaemic conditions and may contribute to the pathogenesis of atherosclerosis. Heparanase-1 (HPR1) specifically degrades heparan sulphate proteoglycans. We therefore sought to determine whether: (1) heparan sulphate reduction in endothelial cells is due to increased HPR1 production through increased reactive oxygen species (ROS) production; and (2) HPR1 production is increased in vivo in endothelial cells under hyperglycaemic and/or atherosclerotic conditions. METHODS HPR1 mRNA and protein levels in endothelial cells were analysed by RT-PCR and Western blot or HPR1 enzymatic activity assay, respectively. Cell surface heparan sulphate levels were analysed by FACS. HPR1 in the artery from control rats and a rat model of diabetes, and from patients under hyperglycaemic and/or atherosclerotic conditions was immunohistochemically examined. RESULTS High-glucose-induced HPR1 production and heparan sulphate degradation in three human endothelial cell lines, both of which were blocked by ROS scavengers, glutathione and N-acetylcysteine. Exogenous H(2)O(2) induced HPR1 production, subsequently leading to decreased cell surface heparan sulphate levels. HPR1 content was significantly increased in endothelial cells in the arterial walls of a rat model of diabetes. Clinical studies revealed that HPR1 production was increased in endothelial cells under hyperglycaemic conditions, and in endothelial cells and macrophages in atherosclerotic lesions. CONCLUSIONS/INTERPRETATION Hyperglycaemia induces HPR1 production and heparan sulphate degradation in endothelial cells through ROS. HPR1 production is increased in endothelial cells from a rat model of diabetes, and in macrophages in the atherosclerotic lesions of diabetic and non-diabetic patients. Increased HPR1 production may contribute to the pathogenesis and progression of atherosclerosis.
