摘要: This study aims to investigate the influence of β-elemene on the secretion of angiotensin II (ANG II) and the expression of angiotensin receptor type 1 (AT1R) in hepatic stellate cells (HSCs). , HSC-T6 were cultured for 24 hours and then treated with different doses of β-elemene (2.5, 5 and 10 mg/L). A control group was also set up. The secretion of ANG II in the supernatant was detected by radioimmunoassay. The mRNA expression of AT1R at 4, 12 and 24 h after treatment was detected by reverse transcription-polymerase chain reaction (RT-PCR), respectively. The protein expression of AT1R was detected by western blot. At the 4th h, the ANG II secretion in the supernatant was significantly inhibited by 10 mg/L β-elemene compared with the control group ( <0.05), while 5.0 mg/L and 2.5 mg/L β-elemene had no inhibitory effect on the secretion of ANG II ( >0.05). At the time point of the 12th h, the secretion of ANG II in the supernatant treated with 10 mg/L and 5.0 mg/L β-elemene was significantly lower than the control ( <0.01, <0.05). Following the treatment with 5.0 mg/L and 2.5 mg/L β-elemene for 24 h, significant inhibition of ANG II secretion was observed ( <0.05), but 10 mg/L β-elemene had no such effect. β-elemene significantly reduced the amount of AT1R mRNA in HSCs after the treatment for 4, 12, and 24 h in a dose-dependent manner. The expression of AT1R protein also decreased after the treatment with β-elemene for 24 h. β-elemene can inhibit the secretion of ANG II and the gene and protein expression of AT1R, which may be the mechanism by which β-elemene prevents the progress of hepatic fibrosis.

Urotensin II receptor antagonist reduces hepatic resistance and portal pressure through enhanced eNOS-dependent

Ruoxi Zhang, Jing Chen, Diangang Liu, Yu Wang

摘要: Increased serum urotensin II (UII) levels in human cirrhotic populations have been recently shown, but the long-term effects of UII receptor antagonist on the cirrhosis have not been investigated. To investigate the therapeutic effects of urotensin II receptor (UT) antagonist palosuran on rats with carbon tetrachloride (CCl )-induced cirrhosis, the hepatic and systemic hemodynamics, liver fibrosis, the metalloproteinase-13 (MMP-13)/ tissue inhibitor of metalloproteinase-1 (TIMP-1) ratio, hepatic Rho-kinase activity, and the endothelial nitric oxide synthase (eNOS) activity are measured in CCl -cirrhotic rats treated with palosuran or vehicle for 4 weeks. Primary hepatic stellate cells (HSCs) are used to investigate the changes in UII/UT expression and the effect of palosuran. Compared with the vehicle-treated cirrhotic rats, treatment with palosuran can reduce the portal pressure (PP), decrease the risk of liver fibrosis and the level of α smooth muscle actin, collagen-I (COL-I), and transforming growth factor β expression. However, treatment with palosuran can increase MMP-13/TIMP-1, p-vasodilator-stimulated phosphoprotein (p-VASP), and p-eNOS expression. Moreover, UII/UT mRNA expression increases during HSC activation. MMP-13/TIMP-1, COL-I, and p-VASP are inhibited after palosuran treatment. Our data indicate that long-term administration of palosuran can decrease PP in cirrhosis, which results from decreased hepatic fibrosis and enhanced eNOS-dependent HSC vasodilatation.

摘要: Little is known about the expression characteristics of the various kinds of possible markers in hepatic stem cells (HSCs) and other HSC-related cells in human fetal liver in various developmental stages. It is significant to investigate the immunohistochemical expression for better understanding of the origin, differentiation and migration of HSCs in the developing human liver. H-E staining and immunohistochemical methods were used to observe the expression of hepatic/cholangiocellular differentiation markers (AFP, GST-, CK7, CK19) and hematopoietic stem cell markers (CD34 and c-kit) in several kinds of HSC-related cells in thirty cases of fetal liver samples (4–35 weeks after pregnancy). AFP expression appears in fetal hepatocytes at four weeks’ gestation. It peaks at 16–24 weeks’ gestation and decreases gradually afterwards. Finally, weak signals were only found in some ductal plate cells and a few limiting plate cells. GST- was detected in hepatic cord cells from the sixth week and in the ductal plate cells from the eighth week. Twenty-six weeks later, only some ductal plate cells and a few limiting plate cells show positive signals. CK19 expression peaks during the 6th–11th weeks in hepatic cord cells and decreases gradually afterwards, except for the ductal plates. CK7 expression was limited in the ductal plate cells and bile ducts cells from the 14th week. CD34 and c-kit were detected at the eighth week in some ductal plate cells and a few mononuclear cells in the hepatic cords/mesenchymal tissue of portal areas. After 21 weeks, CD34 and c-kit were found only in ductal plate cells and a few mononuclear cells in the hepatic mesenchymal tissue of portal areas. Fetal hepatocytes at 4–16 weeks’ gestation are mainly constituted by HSCs characterized with bi-potential differentiation capacity. At 16 weeks’ gestation, most hepatic cord cells begin to differentiate into hepatocytes and abundant HSCs remain in ductal plate (the origin site of Hering canals). It is also indicated that the hematopoietic stem cells may give rise to some HSCs in embryonic liver. These indirectly support the hypothesis about the location and origin of HSCs in liver valley hypothesis reported previously.

摘要:

Metformin has been widely used as a first-line anti-diabetic medicine for the treatment of type 2 diabetes (T2D). As a drug that primarily targets the liver, metformin suppresses hepatic glucose production (HGP), serving as the main mechanism by which metformin improves hyperglycemia of T2D. Biochemically, metformin suppresses gluconeogenesis and stimulates glycolysis. Metformin also inhibits glycogenolysis, which is a pathway that critically contributes to elevated HGP. While generating beneficial effects on hyperglycemia, metformin also improves insulin resistance and corrects dyslipidemia in patients with T2D. These beneficial effects of metformin implicate a role for metformin in managing non-alcoholic fatty liver disease. As supported by the results from both human and animal studies, metformin improves hepatic steatosis and suppresses liver inflammation. Mechanistically, the beneficial effects of metformin on hepatic aspects are mediated through both adenosine monophosphate-activated protein kinase (AMPK)-dependent and AMPK-independent pathways. In addition, metformin is generally safe and may also benefit patients with other chronic liver diseases.

摘要:

Primary hepatic carcinoma (PHC) is a common malignant tumor in China. Cancer is comprehensively treated with various therapeutic regimes, including traditional Chinese medicine (TCM). TCM has been widely used to improve the quality of life, delay the time of cancer progression, and prolong the median survival time. This systematic review with meta-analysis aimed to assess the effect of TCM combined with Western therapy on primary hepatic carcinoma. A comprehensive literature search was conducted in six databases, including CNKI, VIP, Wan-Fang Database, CBM, PubMed, and Cochrane library. A total of 44 randomized controlled trials (RCTs) involving 3429 participants suffering from PHC were selected. Meta-analysis results indicated that the overall effect of TCM and Western integrative treatment on PHC was higher than that of Western intervention alone, which can postpone tumor recurrence and metastasis and prolong the overall survival time of patients with PHC. Although the obtained evidence remained weak because of the poor methodological quality of the included studies, this review provided relevant data supporting the efficacy and safety of TCM combined with Western therapies. In future research, individual RCT studies should incorporate accepted standards for trial design and reporting, proper outcome indicators according to international standards, blinding in allocation concealment, and valid follow-up periods.

摘要: There is no conclusive answer to the question whether excising gall bladder is helpful to the patient with hepatic cancer. The survival rate of patients with hepatic cancer for more than two years has been increased, and the incidence of complications of cholecystitis and gall stone are relatively higher among these patients, which may seriously complicate treatment of advanced hepatic cancer and decrease quality of life. The researchers conducted a prospective clinical investigation from 2002 to 2006 to assess the clinical significance of preventive cholecystectomy in patients with hepatic cancer. One hundred and eighteen cases of postoperative patients with hepatic cancer, who survived for more than two years, were followed up. Based on whether cholecystectomy was performed, the patients were divided into two groups including 48 cases with cholecystectomy and 70 cases with cholecyst reserved. The two-year morbidity of gall stone and morbidity of pain in the right upper abdomen of cholecyst reservation group were 54.29% and 68.57%, respectively, obviously higher than 0.00% and 20.83% of cholecystectomy group. Mainly for those treated with transcatheter arterial chemo-embolization, the morbidity of gall stone was 86.67% ( < 0.01). Therefore, preventive cholecystectomy is strongly recommended during hepatectomy to decrease the incidence of chronic cholecystitis and gall stone, especially for those whose chemotherapy and embolization will be carried out through hepatic artery and portal vein.

摘要: In order to investigate the effect of paeoniflorin (PAE) on hepatic fibrosis of mice with and , a model of hepatic fibrosis caused by schistosomiasis was established in mice infected with cercariae of . Then, PAE was orally administered before and after praziquantel treatment and both therapeutics were given simultaneously at different time points after the infection. The concentration of serum hyaluronic acid (HA) was determined by radioimmunoassay (RIA). Hepatic granuloma and fibrosis were evaluated via HE and Masson staining. The expression of ?-smooth muscle actin (?-SMA), transforming growth factor ?1 (TGF-?1) and collagen I (Col I) protein was detected by immunohistochemistry. The effect of soluble egg antigen (SEA) and PAE on the production of TGF-?1 from mouse peritoneal macrophages (PM?s) was investigated by RT-PCR, Western blotting and ELISA. The effect of TGF-?1 in optimum macrophage-conditioned medium (OPMCM) on the proliferation of hepatic stellate cells (HSCs) and collagen secretion from HSCs with anti-TGF-?1 antibody was explored by MTT assay and ELISA. The results show that PAE could significantly reduce the concentration of serum HA, the size of egg granuloma, the severity of hepatic fibrosis and the expression of ?-SMA, TGF-?1 and Col I protein in the pre-treatment group. However, in sim- or post-treatment group, PAE did not have any significant therapeutic effect. TGF-?1 could be secreted from PM?s stimulated by SEA. Meanwhile, the production of TGF-?1 from PM?s could be depressed significantly by PAE in a concentration-dependent manner. TGF-?1 could promote the proliferation of HSCs and the secretion of collagens. In a word, PAE can prevent hepatic granuloma and fibrosis caused by schistosomiasis japonica through the inhibition of the secretion of TGF-?1 from PM?s, the proliferation and activation of HSCs and the secretion of collagens from HSCs.

《医学前沿(英文)》 2015年 第9卷 第1期   页码 90-99 doi: 10.1007/s11684-015-0390-2

摘要:

Gene therapy provides a potential cure for hemophilia B, and significant progress has been achieved in liver-directed gene transfer mediated by adeno-associated viral vectors. Recent clinical trials involving the use of a self-complementary adeno-associated virus serotype 8-human codon-optimized factor IX (AAV8-hFIXco) vector demonstrated encouraging efficacy with hFIX expression stabilized at 1% to 6% of normal level in patients, but safety concerns related to high vector doses are still present. Thus, further improvement of AAV vectors and hFIX expression cassette may positively contribute to the ultimate success of hemophilia B gene therapy. In this study, to obtain a higher expression level of hFIX that potentiates the coagulant capacity of recipients, human FIX expression vector was optimized by upgrading the codon adaption index and adjusting the GC content, inserting a Kozak sequence (GCCACC), and introducing a gain-of-function mutation, R338L (FIX Padua). The efficiency of the published and the presently constructed cassettes was compared through in vivo screening. In addition, the regulatory elements that control the FIX gene expression in these cassettes were screened for liver-specific effectiveness. Among all the constructed cassettes, scAAV-Pre-hFIXco-SIH-R338L, which was the construct under the control of the prothrombin enhancer and prealbumin promoter, resulted in the highest level of coagulant activity, and the expression levels of two constructed cassettes (scAAV-Chi-hFIXco-SIH-R338L and scAAV-Pre-hFIXco-SIH-R338L) were also higher than that of the published cassette (scAAV-LP1-hFIXco-SJ). In summary, our strategies led to a substantial increase in hFIX expression at the protein level or a remarkably elevated coagulant activity. Thus, these reconstructs of hFIX with AAV vector may potentially contribute to the creation of an efficacious gene therapy of hemophilia B.

摘要: The aim of this study was to explore the expression of integrin-β1 in different stages of hepatic fibrosis and intervention of resveratrol as well as the way by which integrin-β1 promoted hepatic fibrosis. Hepatic fibrosis models of male Sprague Dawley (SD) rats were created and intragastric administration of resveratrol was given in low (40 mg/kg), middle (120 mg/kg) and high (200 mg/kg) dose groups. The expression of integrin-β1, tumor growth factor-β (TGF-β) and tissue inhibitor of metalloproteinase-1 (TIMP-1) in different stages of hepatic fibrosis was detected by using RT-PCR. The expression of hexadecenoic acid (HA) and precollagen III (pc III) was assayed by radioimmunoassay. The expression of integrin-β1, TGF-β and TIMP-1 was determined in each group. Liver function and pathological sections of each group in different stages of hepatic fibrosis was tested to judge the therapeutic efficacy of resveratrol at different doses. The expression of integrin-β1 in normal control group was low and steady and was not increased as the development of hepatic fibrosis, but it is increased in other groups. The expression levels of integrin-β1 in the model control group (0.878±0.03, <0.01) and low dose group (0.855±0.04, <0.01) were higher than other groups, but there was no difference between model control group and low dose group ( >0.05). The expression levels of integrin-β1 and TGF-β in middle dose group and high dose group were higher than other groups ( <0.01). The expression levels of integrin-β1 and TGF-β in model control group and low dose group were lower than the normal control group ( <0.01). The expression levels of TIMP-1 in the model control and low dose groups were higher than the other groups ( <0.01). The expression levels of TIMP-1 in the middle dose group and the high dose group were lower than the normal control group ( <0.01). The expression of integrin-β1 existed in all stages of hepatic fibrosis of SD rats, and it was increased as the development of hepatic fibrosis. The expression of TGF-β and TIMP-1 was consistent with that of integrin-β1 in different stages of hepatic fibrosis. Resveratrol could improve the degree of hepatic fibrosis of SD rats and decrease the expression of integrin-β1 markedly at a dose of 120 mg/kg.

《医学前沿(英文)》 2010年 第4卷 第3期   页码 317-322 doi: 10.1007/s11684-010-0035-4

摘要: The inhibitory effect of different reperfusion periods 45 min following hepatic ischemia on the expression of cholecystokinin (CCK) and vasoactive intestinal peptide (VIP) in the jejunum and the effect of salvia miltiorrhiza pretreatment were investigated, and the possible mechanism and implications were explored. Eighty rats were randomly divided into four groups: normal control group (CO group), sham-operated group (SO group), ischemia/reperfusion (I/R) injury group (IR group) and salvia miltiorrhiza pretreatment group (SM group). The rat model of I/R was established by using a non-invasive artery clamp to clip (45 min) or relax the hepatic pedicle. In the SM group, saline (40 mL/kg) and salvia miltiorrhiza injection (6 g/kg) were injected via the tail vein 30 min before clipping the hepatic pedicle. In the SO group only the porta hepatis was dissected after laparotomy without clamping the hepatic pedicle. At 0, 3, 12, 24 and 72 h post-reperfusion, respectively, upper jejunum samples were taken for immunohistochemistry of CCK and VIP. It was found that 0 h after I/R, the expression of CCK and VIP in the upper jejunum was upregulated. With prolongation of the reperfusion period, the expression of CCK and VIP was also increased, reached the peak at the 24th h, and gradually returned to the normal level at the 72nd h after reperfusion. The levels of both CCK and VIP in the SM group were lower than those in the IR group. It is suggested that the digestive tract congestion injury caused by liver ischemia can upregulate the expression of CCK and VIP in the jejunum following reperfusion. Salviae pretreatment can partly reduce the increased expression of CCK and VIP in the jejunum in the same period, which might contribute to the early recovery of gastrointestinal motility.

摘要: To study the efficacy of Fuganling granula (FGL, 复肝灵颗粒) in treating mouse immunological hepatic injury that was caused by Bacille Calmette Guerin (BCG) and lipopolysaccharide (LPS), a total of 60 mice were adopted, among which, 50 mice were given intraperitoneal injection with BCG and LPS to establish an immunological liver injury model and then were randomly divided into 5 groups (10 mice/group): 4 groups received treatment of FGL orally at the doses of 100 mg/kg (high-dosage), 50 mg/kg (middle-dosage), 25 mg/kg (low-dosage) and bifendate orally at the dose of 80 mg/kg, respectively. One group was treated with distilled water orally. The remaining 10 mice were given distilled water intraperitoneally as the normal control group. The indices of thymus, liver and spleen, and the activities of the alanine aminotransferase (ALT), aspartate aminotransferase (AST) in the serum were detected. Compared to the normal rat, the model group’s thymus index decreased significantly. The liver index and spleen index increased significantly. The activities of serum ALT and AST increased significantly (all < 0.01). Compared to the model control group, the group treated with FGL in high-dosage, middle-dosage or low-dosage can decrease the activities of ALT and AST and the group treated with FGL in high-dosage and middle-dosage can increase the thymus index significantly ( < 0.01). This experiment established the immunological liver injury model successfully and found that FGL has a remarkably protective effect on this kind of immunological hepatic injury.

摘要:

Glucagon-like peptide-2 (GLP-2) has potent anti-inflammatory effects and protects against experimental ischemia/reperfusion (I/R) injury in pulmonary, intestinal, and myocardial tissue. However, its protective abilities against I/R injury in the liver are unknown. We investigated the potential role of GLP-2 pretreatment on hepatic I/R injury in rats. A total of 24 rats were randomly divided into three groups (n = 8). The first group was the control group; the second group was the vehicle-treated hepatic ischemia/reperfusion (HIR, vehicle saline-treated) group; and the third group was the GLP-2 pretreated I/R (GLP2-IR) group. Each rat in the third group was intraperitoneally administered 5 μg GLP-2 for 5 d before the procedure. A portal triad was created to induce ischemia with a vascular atraumatic clamp. After 40 min, the clamp was released to initiate hepatic reperfusion for 6 h. Blood samples and tissue specimens from the liver were obtained. Alanine aminotransferase, aspartate aminotransferase, and total bilirubin levels significantly increased in the saline-treated HIR group (P<0.001), whereas GLP-2 pretreatment significantly decreased their levels (P<0.01). Our data suggested that GLP-2 pretreatment may have a protective effect on liver I/R injury. However, dose-response studies are necessary to determine the most effective dose.

摘要:

It has been demonstrated that β-elemene could protect against carbon tetrachloride (CCl4)-induced liver fibrosis in our laboratory work, and the aim of this paper is to reveal the protective mechanisms of β-elemene. The hepatic fibrosis experimental model was induced by the hypodermical injection of CCl4 in Wistar male rats. β-elemene was intraperitoneally administered into rats for 8 weeks (0.1 mL/100 g bodyweight per day), and plasma endotoxin content was assayed by biochemistry. The serum TNF-α level was detected using radioactive immunity. CD14 expression in rat livers was measured by immunohistochemistry and Western blot. The results showed that β-elemene can downregulate the levels of plasma endotoxins, serum TNF-α, and hepatic CD14 expression in rats with liver fibrosis. β-elemene plays an important role in downregulating the lipopolysaccharide signal transduction pathway, a significant pathway in hepatic fibrosis development.
