ABSTRACT

Malnutrition, sarcopenia, and osteoporosis are common nutrition-related complications in patients with liver cirrhosis. Sarcopenia is an important manifestation of malnutrition, while malnutrition and sarcopenia are risk factors for osteoporosis. There is a close relationship among them, and they all have adverse effects on the clinical outcomes and prognosis of patients with liver cirrhosis. Therefore, it is necessary to identify them as early as possible and take active measures for prevention and treatment. Insufficient intake of nutrients, metabolic disorders, abnormal hormone levels, and lack of physical activity all contribute to the development of malnutrition, sarcopenia, and osteoporosis in patients with liver cirrhosis. In addition, medications commonly used in the treatment of liver diseases, such as glucocorticoids and some antiviral drugs, may have potential impact on bone metabolism, which needs to be taken seriously in clinical practice. Reasonable nutritional intervention, appropriate exercise, and treatment of underlying diseases are the basis of the prevention and treatment of malnutrition, sarcopenia, and osteoporosis. Some targeted drugs can improve these nutrition-related complications, which needs to be confirmed by further studies.

ABSTRACT

Objective:To investigate the expression of nicotinamide adenine dinucleotide (NAD +) digestive enzyme CD38 in normal and endotoxin-tolerant human monocyte THP-1 cell lines treated with lipopolysaccharide (LPS). Methods:(1) Normal THP-1 cells: The experiment and control group were treated with 100 ng/ml LPS for 1, 3, 6, 12 and 24 h or phosphate buffer for 24 h, respectively. Quantitative polymerase chain reaction (PCR) and Western blot were used to measure the expression of interleukin-6 (IL-6) and tumor necrosis factor (TNF) mRNA, CD38 mRNA and protein. (2) The induced endotoxin-tolerant THP-1 cells: ①The model of endotoxin-tolerant cells was established firstly by treating the THP-1 cells with 100 ng/ml LPS for 24 h. THP-1 cells treated with phosphate buffer were set as blank group. After further stimulating the two groups with LPS (100 ng/ml) for 3 h, mRNA levels of IL-6 and TNF were measured by quantitative PCR to determine whether the modeling was successful or not. ②In addition, the expression of CD38 mRNA were detected by quantitative PCR before and 12 h after LPS stimulation, and the expression of CD38 protein of these two groups were detected by western blotting before and 1, 6 h after LPS stimulation. Two independent samples t-test and repeated measurement analysis of variance were used for statistical analysis. Results:(1) In normal THP-1 cells, the mRNA expression levels of IL-6 and TNF in the LPS-stimulated cells were significantly higher than those of the control at all time points. And a higher expression level of CD38 mRNA and protein was observed in LPS-stimulated cells from 3 to 24 h compared with the control (mRNA at 3 h: 2.27±0.03 vs 1.00±0.18; protein at 3 h: 1.47±0.14 vs 1.00±0.16, both P<0.05). (2) Endotoxin-tolerant THP-1 cells: ①IL-6 and TNF mRNA levels in the model group were significantly lower than those in the blank group (both P<0.05), indicating that the endotoxin-tolerant THP-1 cell model was established successfully. ②Compared with the same points in the blank group, CD38 mRNA expression was upregulated in the model group before stimulating by LPS (14.18±1.19 vs 1.00±0.13, t=19.007) and 12 h after LPS stimulation (28.33±3.98 vs 7.61±0.88, t=8.803). Moreover, CD38 protein levels before stimulating by LPS (1.54±0.06 vs 1.00±0.10, t=7.796) and 1 h (1.59±0.09 vs 1.07±0.17, t=4.721), 6 h after LPS stimulation (2.48±0.09 vs 1.43±0.12, t=12.233) in the model group were all higher than those in the control group (all P<0.05). The intra-group comparison showed that in the model group the levels of CD38 mRNA at 12 h and CD38 protein at 6 h after LPS stimulation were significantly higher than those before (both P< 0.05). Conclusions:In both normal and endotoxin-tolerant THP-1 cells, LPS upregulates the expression of CD38, which is an NAD + digestive enzyme, and an indirect indicator of NAD + level in monocyte reinfection at the stage of immunosuppression. This study provides a preliminary reference for further investigation on the applicability of CD38 as a potential biological marker in the clinical diagnosis of neonatal sepsis.

ABSTRACT

ObjectiveTo investigate the risk factors for rebleeding within 5 years and the influencing factors for 5-year survival in patients with liver cirrhosis and severe esophagogastric variceal bleeding (EVB). MethodsA retrospective analysis was performed for 129 patients with liver cirrhosis who attended Tianjin Third Central Hospital from May 2012 to May 2014 due to severe EVB for the first time, with a follow-up time of 5 years. Related clinical data were analyzed, including age, sex, cause of liver cirrhosis, presence or absence of infection at the first time of bleeding, liver stiffness measurement (LSM), splenic stiffness measurement (SSM), portal vein diameter, biochemical parameters, rebleeding time, and prognosis. Esophagogastric variceal rebleeding was defined as the primary endpoint and death was defined as the secondary endpoint. The t-test was used for comparison of continuous data between two groups, and the chi-square test was used for comparison of categorical data between two groups; a logistic regression analysis was used to investigate the independent risk factors for rebleeding, and a Cox regression analysis was used to analyze the predictive indicators for 5-year survival in EVB patients; the Kaplan-Meier curve was used to analyze the cumulative non-rebleeding rate. ResultsAmong the 129 patients, 87(67.4%) experienced rebleeding during follow-up. There were significant differences between the rebleeding group and the non-rebleeding group in the proportion of patients with alcoholic cirrhosis (χ2=4.896, P=0.027), portal vein diameter (t=2.203, P=0.030), LSM(Z=-2.771, P=0.006), and SSM(t=2.678, P=0.010). The patients with alcoholic cirrhosis had a significantly higher mean number of times of bleeding than those with non-alcoholic cirrhosis (all P<0.05). The multivariate logistic regression analysis showed that alcoholic cirrhosis (odds ratio [OR]=5.687, 95% confidence interval [CI]: 1.230-26.129, P=0.025), LSM(OR=1.039, 95% CI: 1.010-1.070, P=0007), and SSM(OR=1.078, 95% CI: 1.028-1.129, P=0.001) were independent risk factors for rebleeding within 5 years after treatment in EVB patients. Among the 129 patients, 45 (34.9%) died. The univariate Cox regression analysis showed that there were significant differences between the death group and the survival group in age, times of bleeding, mean arterial pressure, portal vein diameter, aspartate aminotransferase, lymphocyte percentage, and presence or absence of infection at the first time of bleeding (all P<005). Further multivariate analysis showed that 5-year survival rate was associated with portal vein diameter (OR=1.459, 95% CI: 1056-2.014, P=0.022), age (OR=1.053, 95% CI: 1.006-1.103, P=0.026), times of bleeding (OR=1.286, 95% CI: 1.040-1.591, P=0.020), and presence or absence of infection at the first time of bleeding (OR=5.239, 95% CI: 1.750-15.641, P=0.003). ConclusionAlcoholic cirrhosis, LSM, and SSM are independent risk factors for rebleeding within 5 years in EVB patients, and age, times of bleeding, portal vein diameter, and presence or absence of infection at the first time of bleeding are associated with 5-year survival.

ABSTRACT

Hepatitis B virus infection is one of the primary causes of liver cirrhosis and liver cancer. The use of antiviral drugs significantly reduces the risk of liver cancer in patients with chronic hepatitis B (CHB), but some of the patients who receive antiviral drugs for a long time still develop liver cancer. Therefore, it is necessary to early identify and predict the risk of liver cancer in such patients. Currently, several models for predicting the risk of liver cancer during antiviral therapy in CHB patients have been developed based on the risk factors such as liver cirrhosis, age, sex, liver stiffness, virology, serological markers, alcohol consumption, and history of diabetes, including REACH-B, PAGE-B, mPAGE-B, APA-B, CAMD, AASL, and REAL-B. This article reviews the research advances in the models for predicting the risk of liver cancer during antiviral therapy in CHB patients.

ABSTRACT

ObjectiveTo investigate the clinical features of patients with severe alcoholic hepatitis (AH) with different underlying liver diseases and the influencing factors for short-term prognosis. MethodsA retrospective analysis was performed for the clinical data of 170 patients with severe AH who were admitted to Tianjin Third Central Hospital from August 2004 to August 2018, and according to the underlying liver disease, they were divided into group A (27 patients without liver cirrhosis), group B (52 patients with compensated liver cirrhosis), and group C (91 patients with decompensated liver cirrhosis). Related scores were calculated, including Maddrey’s discriminant function (MDF) score, Chronic Liver Failure-Sequential Organ Failure Assessment (CLIF-SOFA) score, Model for End-Stage Liver Disease (MELD) score, age-bilirubin-international normalized ratio-creatinine (ABIC) score, and Glasgow alcoholic hepatitis score (GAHS). An analysis of variance or the Kruskal-Wallis H test was used for comparison of continuous data between multiple groups, and the chi-square test was used for comparison of categorical data between multiple groups. Univariate and multivariate Cox regression analyses were used to screen out the independent influencing factors for the short-term prognosis of patients with severe AH. The Kaplan-Meier method was used to plot survival curves, and the log-rank test was used for comparison of survival rate between groups. The receiver operating characteristic (ROC) curve was used to calculate the area under the ROC curve (AUC) and 95% confidence interval (CI), sensitivity, and specificity for each predictive model, and the DeLong method was used for comparison. ResultsThe 28-day survival rates of patients in groups A, B, and C were 88.9%, 80.8%, and 51.6%, respectively, with a significant difference between the three groups (χ2=1983, P<0.001). The AUCs (95% CIs) of MELD score, MDF score, GAHS score, ABIC score, and CLIF-SOFA score were 0.584 (0.493-0.676), 0.696 (0.605-0.786), 0.644 (0.554-0.735), 0.745 (0.662-0.827), and 0.795 (0.726-0.863), respectively, in predicting 28-day mortality rate, and there were significant differences between CLIF-SOFA score and MDF, MELD, and GAHS scores (all P<0.05); CLIF-SOFA score had a sensitivity of 79.0% and a specificity of 67.9% at the optimal cut-off value of 850 points in predicting 28-day mortality rate. Different underlying liver diseases (hazard ratio [HR]=2.296, 95% CI: 1.356-3887, P=0.002) and hepatic encephalopathy (HR=1.911, 95% CI: 1.059-3.449, P=0.031) at disease onset were risk factors for 28-day prognosis. ConclusionPatients with severe AH with different underlying liver diseases have different clinical features and short-term prognoses. Different underlying liver diseases and hepatic encephalopathy at disease onset are closely associated with the 28-day prognosis of patients with severe AH. CLIF-SOFA score can predict the 28-day prognosis of patients with severe AH.

ABSTRACT

ObjectiveTo investigate the clinical effect of elbasvir/grazoprevir in the treatment of patients with genotype 1b chronic hepatitis C (CHC). MethodsA total of 99 patients with genotype 1b CHC and compensated cirrhosis who received elbasvir/grazoprevir treatment for 12 weeks and completed treatment and follow-up for 12 weeks after drug withdrawal in Tianjin Third Central Hospital from December 2018 to October 2019 were enrolled. Related clinical data, serological markers, virological indices, and liver stiffness measurement were collected at baseline, at the end of treatment, and at week 12 after drug withdrawal, and virologic response was observed. The Friedman test and Wilcoxon signed rank sum test were used to observe virologic response rate and the changes in liver function and liver stiffness measurement at the end of treatment and at week 12 after drug withdrawal, and the safety of elbasvir/grazoprevir was evaluated. ResultsFor the 99 patients treated with elbasvir/grazoprevir for 12 weeks, the proportion of patients with HCV RNA below the lower limit of detection was 100% at the end of treatment and 99% at week 12 after drug withdrawal. There were significant reductions in alanine aminotransferase (ALT) and aspartate aminotransferase (AST) from baseline to the end of treatment (Z=-5.857 and -5.941, both P<0.05). Liver stiffness measurement decreased from 10.5 kPa at baseline to 8.0 kPa at week 12 after drug withdrawal (Z=-4.036, P<0.05). Among the 99 patients, 24 patients with compensatory cirrhosis reached a virologic response rate of 100% at the end of treatment and at week 12 after drug withdrawal, as well as significant reductions in ALT and AST from baseline (both P<0.05), and liver stiffness measurement decreased from 21.1 kPa at baseline to 17.5 kPa at the end of treatment (Z=-1.832, P=0.067) and 13.6 kPa at week 12 after drug withdrawal (Z=-3.182, P=0.001). Compared with the non-liver cirrhosis group, the liver cirrhosis group had significantly greater reductions in liver stiffness measurement (P<0.05). The patients had good tolerance throughout the treatment, and 4 patients reported mild adverse events during the treatment. ConclusionPatients with genotype 1b CHC have a high virologic response rate to elbasvir/grazoprevir in the real world, with significant improvements in liver function and liver stiffness measurement and good tolerance.

ABSTRACT

Objective@#To study the occurrence of sarcopenia in patients with liver cirrhosis, and to explore their risk factors and impact on clinical outcomes.@*Methods@#199 hospitalized cases with liver cirrhosis were collected for nutritional risk screening, anthropometric measurement and blood biochemical examination. The body composition analysis was measured based on the skeletal muscle content of the four limbs to calculate the appendicular skeletal muscle mass index (ASMI). Patients were divided into sarcopenia and non-sarcopenia group and the relevant indexes of both groups were compared to screen for factors affecting the occurrence of sarcopenia. During the follow-up of 48 months, the survival and complications of the both groups were compared. Statistical analysis was performed using t-test, χ2 test and logistic regression analysis in terms of different data.@*Results@#The incidence of sarcopenia in cirrhosis was 36.7%, with the highest prevalence in patients with recurrent hepatic encephalopathy (62.5%), followed by patients with abdominal ascites / pleural effusion (37.6%). The incidence of sarcopenia was significantly higher in those with nutritional risk than in those without nutritional risk (P < 0.05). However, even among those without nutritional risk, 14.8% had combined sarcopenia. The body mass index (BMI), upper arm muscle circumference (AMC), and body cell mass (BCM) of the sarcopenia group were lower than those of the non-sarcopenia group (P < 0.05), and the edema index (ECW/TBW) was higher than the latter (P < 0.05). Multivariate analysis showed that age, gender, BMI, and complications of hepatic encephalopathy were the main influencing factors of cirrhosis combined with sarcopenia (P < 0.05). During the follow-up period, the sarcopenia group had a higher mortality rate than non-sarcopenia goup (P < 0.05), and the incidence of recurrent abdominal ascites/pleural effusion, hepatic encephalopathy, and infection was also significantly elevated (P < 0.05).@*Conclusion@#Sarcopenia is one of the manifestations of malnutrition in patients with liver cirrhosis, which increases the risk of mortality and other complications, and has adverse impact on the clinical outcome. Additionally, older age, male sex, low BMI and recurrent hepatic encephalopathy has higher risk for developing sarcopenia.

ABSTRACT

To investigate the mechanism of long non-coding RNA plasmacytoma variant translocation 1 (PVT1) in gastric cancer caused by (HP) infection. The expression of PVT1 was detected by quantitative real-time polymerase chain reaction in HP-infected normal gastric epithelial cells GES-1. Gastric cancer cell line SGC-7901 was transfected with PVT1 small interfering RNA and co-cultured with HP,and then the inflammatory cytokines such as tumor necrosis factor-α (TNF-α),interleukin (IL) -1β,IL-6 and IL-8 were detected. After PVT1 was knocked down,the effects of PVT1 on the proliferation and migration of gastric cancer cells were examined by cell scratch assay. RNA-pulldown combined with mass spectrometry was used to detect the protein binding to PVT1,and the result of mass spectrometry was verified by RNA-pulldown combined with Western blot. In HP-infected normal gastric epithelial cells GES-1,quantitative real-time polymerase chain reaction showed that PVT1 was significantly up-regulated (=7.160,=0.019). PVT1 was knocked down in gastric cancer cells,and then infected with HP. The expressions of inflammatory factors including TNF-α (=3.899,=0.011),IL-1β (=14.610,=0.000),and IL-8 (=6.557,=0.001) were significantly inhibited. Although PVT1 knockdown had no significant effect on the proliferation ability of gastric cancer cells,it inhibited the migration of cells. PVT1 might interact with RPS8 protein. PVT1 may act as a pro-inflammatory factor and regulate gastric cancer caused by HP infection.

ABSTRACT

At present, there is still a lack of uniform treatment strategies for hepatocellular carcinoma (HCC). Immunotherapy, especially PD-1/PD-L1 checkpoint inhibitors, is a novel therapy for HCC and can bring survival benefits to patients with advanced HCC. However, research data show that only a small number of HCC patients can benefit from this treatment regimen. To date, few biomarkers have been reported to predict the clinical effect of PD-1/PD-L1 checkpoint inhibitors in HCC patients. This article reviews the biomarkers studied for HCC and other tumors and explores the possible predictive factors for the clinical effect of PD-1/PD-L1 checkpoint inhibitors in HCC, in order to optimize the selection of treatment population and improve the clinical effect of PD-1/PD-L1 checkpoint inhibitors in the treatment of HCC.

ABSTRACT

Anemone flaccida Fr. Schmidt is a perennial medicinal herb that contains pentacyclic triterpenoid saponins as the major bioactive constituents. In China, the rhizomes are used as treatments for a variety of ailments including arthritis. However, yields of the saponins are low, and little is known about the plant's genetic background or phytohormonal responsiveness. Using one-quarter of the 454 pyrosequencing information from the Roche GS FLX Titanium platform, we performed a transcriptomic analysis to identify 157 genes putatively encoding 26 enzymes involved in the synthesis of the bioactive compounds. It was revealed that there are two biosynthetic pathways of triterpene saponins in A. flaccida. One pathway depends on β-amyrin synthase and is similar to that found in other plants. The second, subsidiary ("backburner") pathway is catalyzed by camelliol C synthase and yields β-amyrin as minor byproduct. Both pathways used cytochrome P450-dependent monooxygenases (CYPs) and family 1 uridine diphosphate glycosyltransferases (UGTs) to modify the triterpenoid backbone. The expression of CYPs and UGTs were quite different in roots treated with the phytohormones methyl jasmonate, salicylic acid and indole-3-acetic acid. This study provides the first large-scale transcriptional dataset for the biosynthetic pathways of triterpene saponins and their phytohormonal responsiveness in the genus Anemone.

ABSTRACT

The chemical constituents from Brassica rapa were identified by various chromatographic techniques including silica gel, reversed-phase silica gel, macroporous resin and Sephadex LH-20 column chromatography. Eight compounds were isolated from this plant. The isolated compounds were elucidated by physicochemical properties and spectroscopic methods, including extensive 1D, 2D-NMR, and HR-ESI-MS techniques. Compounds 1, 2 are new triterpenoids and 3-7 were isolated for the first time from Brassica rapa. The cytotoxic effect of compounds 1 and 2 were tested by MTT assay against five cancer cell lines. The result showed that all compounds exhibit growth inhibition for the cancer lines. Compound 1 has an IC50 value of 5.87 μmol·L-1 for growth inhibition of leukemia cell line HL-60, and IC50 value for compound 2 was 10.32 μmol·L-1.

ABSTRACT

ObjectiveTo investigate the effect of recombinant human granulocyte colony-stimulating factor (rhG-CSF) on acute liver failure (ALF) induced by D-galactosamine (D-GalN) in rats. MethodsA total of 105 male Sprague-Dawley rats were randomly divided into healthy control group, liver failure model group, and rhG-CSF group, with 35 rats in each group. A rat model of ALF was established by intraperitoneal injection of D-GalN (1400 mg/kg). Alanine aminotransferase (ALT) level in the liver, total bilirubin (TBil), peripheral blood leukocyte count, and liver pathological changes were observed at 12, 24, 48, 72, and 120 hours after modeling, and survival rate was observed at 120 hours after modeling. A one-way analysis of variance was used for comparison of continuous data between multiple groups, and the LST-t test was used for further comparison between two groups. ResultsCompared with the liver failure model group, the rhG-CSF group had a significantly higher degree of hepatocyte degeneration and necrosis at all time points except 120 hours after modeling, and compared with the liver failure model group at 120 hours after modeling, the rhG-CSF group had better recovery of lobular structure on HE staining. Compared with the liver failure model group, the rhG-CSF group had a tendency of increase in the percentage of cells with positive tumor necrosis factor-α at the five time points after modeling. Compared with the liver failure model group, the rhG-CSF group had significantly higher levels of ALT and TBil at all five time points. Both groups had a significant change in ALT level at 24 hours after modeling (P<0.05), as well as a significant change in TBil at 24, 48, and 120 hours after modeling (P<0.05). The rhG-CSF group had a significantly higher peripheral blood leukocyte count than the liver failure model group at all five time points (all P<005). There was no significant difference in survival rate at 120 hours after modeling between the two groups (P>0.05). ConclusionApplication of rhG-CSF during the stage of acute inflammatory reaction of ALF may aggravate liver inflammatory response.
