Figure 2AB shows the changes in the distributions of the Knodell necroinflammatory and Ishak fibrosis scores at the baseline, at week 48, and over the long term. One of the 57 patients had an increase in the Ishak fibrosis score, which rose from 1 at the baseline to 2 at the time of long-term biopsy. This patient had an undetectable HBV DNA level and a normal serum ALT level at the time of long-term biopsy as well as an improvement in the necroinflammatory score (from 3 at the baseline to 1 at the time of long-term biopsy). Ten of the 57 patients had advanced fibrosis or cirrhosis (Ishak score ≥4) at the baseline. With long-term entecavir therapy, all

10 patients demonstrated at least a 1-point reduction Selleckchem HIF inhibitor in the Ishak fibrosis score with a median reduction from the baseline of 1.5 points. Four of the 10 patients had cirrhosis at the baseline (Ishak fibrosis score ≥5), and all demonstrated an improvement in the Ishak fibrosis score with a median drop of 3 points (range = 1-4). Figure 3 shows photomicrographs of biopsy samples taken from a 60-year-old, HBeAg-negative, Caucasian male. The baseline biopsy sample showed an Ishak fibrosis score Cobimetinib order of 6, which indicated cirrhosis; it was unchanged at

week 48. After long-term treatment with entecavir, the week 268 biopsy sample showed an Ishak fibrosis score of 2, which indicated minimal fibrosis. At the time of long-term biopsy, 100% of patients (57/57) had an HBV DNA level <300 copies/mL (Table 2). This represents an increase from 70% of patients (40/57) with an HBV DNA level <300 copies/mL after 48 weeks of entecavir treatment. Similarly, the proportion of patients with an ALT level ≤1 times the upper limit of normal increased from

67% (38/57) after 48 weeks of therapy to 86% (49/57) after long-term treatment. Genotypic testing for resistance was not performed because all the patients achieved a serum HBV DNA level <300 copies/mL. According to the medchemexpress study design of ETV-022, patients who lost HBeAg (with or without seroconversion) during the first or second year of therapy and achieved undetectable serum HBV DNA by branched DNA assay were to discontinue entecavir treatment and be followed off-treatment to determine the sustained response. During the long-term rollover study, 55% of the HBeAg-positive patients (22/40) lost HBeAg, and 33% (13/40) achieved hepatitis B e (HBe) seroconversion. No patient in this cohort lost HBsAg. The majority of patients (96%) experienced at least one adverse event at some time during entecavir treatment, and serious adverse events (the majority of which were grade 1 or 2) occurred in 25% of patients. However, no patient discontinued entecavir treatment because of an adverse event. Two patients experienced on-treatment ALT flares; both cases were resolved with continued treatment.

We conclude that Yap induces metabolic reprogramming in the liver, resulting in decreased ammonia detoxification (Urea cycle) and increased click here ammonia assimilation into glutamine, prior to tumor formation. We hypothesize that the Yap-driven accumulation of glutamine may provide essential components for rapid cell proliferation that may contribute to hepatic growth in liver development and tumorigenesis.

Hwang, Sebastian Beltz, Kimberley Evason, Keelin O’Connor, Kristin Brown, Evan C. Lien, Sagar selleck chemicals Chhangawala, Yariv Houvras, Didier Y. Stainier Introduction: Acute liver failure leads to a variety of complications with one of the most difficult to manage clinically being the neurological complications, collectively called hepatic enceph-alopathy (HE). Following liver damage, the liver upregulates a variety of factors in response to injury. Transforming

growth factor beta 1 (TGF 1) is involved in the promotion of liver fibro-sis and is elevated in the serum following liver injury. Insulin-like growth factor 1 (IGF-1) is a neuroprotective peptide that is anti-inflammatory and can be suppressed by TGF 1 signaling in other organs. Therefore, we hypothesize that circulating hepatic-derived TGF 1 suppresses neural IGF-1 during

HE and subsequently exacerbates the neurological decline associated with HE. Methods: Male C57Bl/6 mice were injected with the hepatotoxin azoxymethane (AOM; 100 mg/kg). In parallel, mice were pretreated with an anti-TGF neutralizing antibody (1 mg/kg) 1 hour prior to AOM, or were infused ICV with recombinant mouse IGF-1 (120 ng/mouse/day) for 3 days prior to AOM injection. Cognitive impairment was monitored and at coma, livers, serum and whole brains were collected. Liver histology was assessed by H&E stains and liver function was determined via ALT and bilirubin measurement. TGF 1, IGF-1, and the microglia marker IBA-1 were assessed by immu-noblotting, immunohistochemistry and/or RT-PCR. Results: Mice injected with AOM had elevations of hepatic and circulating MCE TGF 1 as well as a suppression of cortical IGF-1. Treatment of AOM mice with anti-TGF neutralizing antibodies or IGF-1 ICV prior to AOM significantly reduced the rate of neurological decline without causing significant changes in liver damage or function when compared to mice only treated with AOM. Mice treated with anti-TGF observed an increase of IGF-1 mRNA in the cortex. Treatment with both anti-TGF and IGF-1 ICV was found to reduce microglia activation and proliferation as measured by IBA1 staining. Conclusion: Elevated TGF 1 following liver failure leads to decreased IGF-1 expression, increased inflammation, and worse outcomes for HE mice.

The aim of this

study was to evaluate the prevalence and predictors of GERD and the effect of GERD on quality of life (QOL) and pregnancy outcomes in Korean pregnant women. Methods: This study was a prospective, cohort study which followed pregnant women in the second or third trimester. Ninety-four consecutive pregnant women who visited Seoul National University Boramae Hospital for the prenatal test were included in this study. GERD was diagnosed with the use of the GERDQ (gastroesophageal reflux disease questionnaire). QOL in pregnant women with GERD was assessed using QOLRAD (quality of life in reflux and dyspepsia questionnaire). Pregnancy outcome was evaluated with obstetric records after delivery. Results: Twenty eight (29.8%) of 94 women were diagnosed as GERD by GERDQ. History of selleck compound GERD in pre-pregnancy and BMI of pre-pregnancy were associated with the development of GERD during pregnancy (9% vs 25%, P = 0.041/ 21.04 ± 2.82 vs 19.97 ± 1.90, P = 0.036). On aspects of QOL, emotional stress (P = 0.014), sleep problem (P = 0.015), food/drink problem (P = 0.004), and vitality (P = 0.029) were more prevalent in pregnant women with GERD.

Pregnancy outcomes as assessed by birth weight, Apgar score, pre-term birth, and gestational age at partum were not different between the two groups. Conclusion: The prevalence of GERD during pregnancy was 29.8% in our cohort. Previous Selleckchem PF-562271 history of GERD and lower BMI in pre-pregnancy can be the predictive factors of the development of GERD in pregnant women. GERD significantly impaired QOL

of pregnant women. Key Word(s): 1. Gastroesophageal reflux disease; 2. pregnancy; 3. outcome; 4.

In the stomach, mechanism of epithelial-mesenchymal interaction has not yet fully elucidated. The aim was to produce 上海皓元医药股份有限公司 a culture system to enable study of gastric epithelial-mesenchymal interaction. Methods: Glandular stomach cells from postnatal day 2 C57 BL/6 J mice were cultured in our three-dimensional (3D) primary culture system. We established mouse gastric mesenchymal myofibroblast (GMF) cell line and cocultured in collagen gels in our 3D culture system. This culture system maintains the cultured cells that are embedded in a collagen gel under an air-liquid interface environment. Results: Cultured stomach cells showed outer spindle cells and yielded expanding sphere structures, which grew for three months. In coculture system with GMF cells, the size and the number of cultured spheres were significantly greater than in control culture. The wall of cultured gastric spheres consisted of a monolayer of tall columnar cells with round nuclei at the base and mucus cytoplasm.

The combined effects of stringent donor selection criteria, HCV antibody testing of donated blood, minipool HCV PCR testing and the use of dual viral elimination methods has resulted in extremely low residual risk of HCV transmission. Recombinant factor products are free from the risk of HCV transmission as they do not contain material Vemurafenib obtained from human blood. The majority of

patients exposed to blood components and factor concentrates prior to the introduction of viral inactivation procedures in the mid 1980s will have been tested for HCV infection at their treatment centres. However, it is likely that there are a significant number of patients with mild disorders who have received concentrate on a single or several occasions and contracted HCV but have not been followed up and tested. All patients with bleeding disorders who received blood products before 1992 should be tested for HCV antibody using a third generation ELISA www.selleckchem.com/products/Rapamycin.html test. Patients who are HCV antibody positive should undergo

HCV RNA PCR testing to determine whether or not they have naturally cleared their infection. RNA PCR positive patients should be referred to a hepatologist for further assessment including RNA quantitation, HCV genotyping and for assessment of the stage of liver damage. HCV RNA negative patients who have cleared the infection naturally should be counselled but long-term hepatology follow up is not required. Biomarkers.  A number of algorithms based on biochemical test results including the aspartate aminotransferase to platelet ratio index (APRI score), Fibrometer, FIB-4 and Fibrotest have been developed to predict the severity of the liver disease [8–11]. For example, the Fibrotest combines the following medchemexpress parameters in a patented algorithm to derive a score which correlates with liver disease severity: age, gender, alpha-2-macroglobulin, haptoglobin, gamma-GT, total bilirubin and apolipoprotein A1. These non-invasive methods,

however, have limited value. Whilst they are useful in defining patients with cirrhosis or with only mild liver disease, they are not useful in the assessment of intermediate stages of disease which the majority of patients have [12]. Few studies have been performed assessing these methods in HCV infected haemophilia patients. Maor et al. compared Fibrotest and Fibroscan (see below) assessment of the stage of liver disease in 57 haemophilic patients with active HCV infection and reported reasonable correlation in patients with cirrhosis but poorer concordance in those with milder degrees of fibrosis [13]. Vidovic et al. combined APRI and FIB-4 assessments in 174 HCV infected haemophilia patients and demonstrated good correlation with the stage of liver disease as determined by Fibroscan score. Again the concordance rates were highest in patients with cirrhosis [14]. Transient elastography.

Among 13 subjects with malignancy-associated PLNE, para-aortic lymph nodes were also enlarged in eight. Among 40 subjects with PLNE of unknown etiology, 27 could be followed up for the mean period of 2.08 years, where no underlying disorders were newly determined with largely unaltered size of PLNE. The incidence of selleck chemicals PLNE in the general population may vary with the prevalence of chronic liver disease, especially HCV infection. When PLNE is observed, liver disorders should be first surveyed including

HCV infection even with normal serum alanine aminotransferase levels. PLNE with para-aortic lymph node enlargement may be suggestive of a malignant lesion. The incidence of PLNE of unknown etiology may be approximately 1% in the general population, which may be just followed up without further change. “
“Liver stiffness measurement (LSM) using transient elastography (FibroScan®) is a useful tool to assess fibrosis in various chronic liver diseases. However, studies were mainly performed in Western countries and largely focused on chronic hepatitis C (CHC). We therefore carried out a multi-center study to validate the accuracy of LSM in the assessment of liver fibrosis in a

large cohort of Chinese patients with chronic hepatitis B (CHB). We compared LSM results to histological staging and serum fibrosis markers (5 direct markers, APRI and FIB-4) using Spearman correlation analysis and Area Under ROC Curves (AUROCs). 469 patients were enrolled and eligible for statistical Crizotinib purchase analysis. LSM in F0 to F4 was 5.5 ±1.7, 5.8 ±2.2, 7.6 ±3.4, 14.5 ±10.8, and 22.3 ±13.6 kPa, respectively (correlation with fibrosis stage

r=0.522, p<0.001). AUROC for LSM to correctly allocate patients to histological fibrosis stage ≥F2, ≥F3 and F4 was 0.82, 0.88, and 0.90, respectively. LSM outperformed serum fibrosis markers 上海皓元医药股份有限公司 for detection of fibrosis F≥2 and F4. Patients with ALT levels 1-5x and >5x the upper limit of normal values had significantly higher stiffness values than stage-matched patients with normal ALT. Transient elastography is a reliable non-invasive technique to predict significant liver fibrosis in Chinese patients with CHB, being superior to current biomarker panels. However, enhanced inflammatory activity can lead to elevated stiffness values unrelated to histological fibrosis stage. “
“Background: Despite the fact that the toxic response to APAP is initiated by reactive metabolites, there is growing evidence that sterile inflammation caused by DAMPs released from dying hepatocytes contribute to APAP hepatotoxicity. CD44, a transmembrane adhesion molecule widely expressed in immune cells as well as parenchymal cells, has multiple functions in regulating leukocyte migration and inflammation through CD44-hyaluronan(HA) interactions. HA fragments could act as an endogenous DAMP to stimulate inflammation.

This diet is only choline-deficient and thus is ideal for studying the sequential progression of steatohepatitis producing human NAFLD. This work is important because Kodama et al.16 demonstrated that JNK1 in hematopoietic (non–insulin-producing) cells is indispensable for hepatic steatosis–induced inflammation by Kupffer cell activation. To better define the tissue-specific function of JNK1, in vivo knockdown in mice has been assessed with different experimental www.selleckchem.com/products/byl719.html approaches. Antisense oligonucleotides,1 adenovirus-mediated delivery of JNK1 short hairpin RNA,11 and transgenic expression of a mitogen-activated

protein kinase phosphatase (dual specificity phosphatase 9)17 suppress JNK activation. Collectively, these approaches demonstrate increased insulin sensitivity, loss of susceptibility to hepatic steatosis, and reduced hepatic triglyceride content concomitant with decreased liver injury and cell death.1, 13 Recently, Davis’ group established conditional JNK1 knockout animals. These animals are a major breakthrough for better defining the tissue-specific role of JNK1 in the pathophysiology of obesity-related diseases.18, 19 In the present report,20 the group used hepatocyte-specific JNK1 knockout (JNK1Δhepa) mice. Interestingly, these mice exhibited glucose intolerance

in contrast to several previous studies employing intravenous delivery of adenoviruses.11, MG-132 concentration 21 Potentially, these differences can be explained by the disruption of JNK1 signaling in different cell types because this approach lacks absolute hepatocyte specificity. Additionally, JNK1Δhepa mice showed decreased hepatic protein kinase B (AKT) activation associated with reduced insulin-stimulated tyrosine phosphorylation of the insulin receptor and IRS-1. MCE They also found triglyceride accumulation linked to increased dietary lipid absorption, decreased fat oxidation, and/or increased

lipogenesis. Thus, de novo lipogenesis may contribute to steatosis in JNK1Δhepa mice. Indeed, livers from these mice exhibited increased expression of genes that promote hepatic lipogenesis, such as peroxisome proliferator-activated receptor gamma coactivator 1β (PGC1β; a key activator of hepatic lipogenesis) and sterol regulatory element binding protein 1 (SREBP1), and a concomitant increase in microsomal triacylglycerol transfer protein (MTP). The important role of MTP for lipoprotein assembly has also been confirmed by other studies.11, 22, 23 In Fig. 1, the existing data and the conclusions taken from Sabio et al.’s report20 are depicted, and the important role of JNK1 in metabolic syndrome is shown. Insulin resistance represents a central characteristic of type 2 diabetes. Free fatty acids and proinflammatory cytokines (e.g., TNF) modulate JNK1 activity. JNK1 activation increases IRS-1 phosphorylation and prevents its interaction with the insulin receptor; this results in insulin resistance.

Methods: Female Dark Agouti rats (n = 8/group) were gavaged with water, Olive Oil (OO) or EO once daily (1 ml), injected with 5-Fluorouracil (5-FU) or saline on day 5 and euthanized on day 8, 9, 10 or 11. Intestinal villus height (VH) and crypt depth (CD), neutral mucin-secreting goblet cell (GC) count, myeloperoxidase (MPO) activity and selected cytokines were quantified. p < 0.05 was considered significant. Results: 5-FU significantly decreased PLX4032 small intestinal VH on days 8 and 9, compared to normal controls (p < 0.05). In 5-FU-injected rats, only EO administration significantly increased VH in the ileum (day 8; 33%), jejunum and jejunum-ileum (JI) junction (day 9; 29%

and 45%, respectively) compared to 5-FU controls (p < 0.05). JI CD was significantly increased by 5-FU on days 9 (20%) and 10 (26%), compared to normal controls. OO and EO administration further increased JI CD on days 9 and 10, compared to 5-FU controls (p < 0.01). GC count was significantly reduced by 5-FU (jejunum: days 8 [41%] and 9 [30%]; ileum: day 8 [47%]; p < 0.05) and EO increased ileal GC on days 10 (75%) and 11 (54%) compared to 5-FU controls (p < 0.05). MPO activity was significantly increased in jejunum (days 8 [277%] and 9 [137%]) and ileum (day 8; 6-fold) following 5-FU

injection, compared to normal controls (p < 0.05). Both EO and OO significantly reduced jejunal MPO on days 8 (OO: 45%; EO 62%) and 9 (OO: 71%; EO: 83%), however, only EO decreased ileal MPO

on day 8 (55%; p < 0.05). Cytokine levels were not significantly affected by either oil or 5-FU administration at the day 8 time this website point (p > 0.05). Conclusions: Promotion of repair from injury could represent a new mechanism of action MCE公司 for Emu Oil, suggesting potential as an adjunct to conventional treatment approaches for cancer management. JE BAJIC,1 GS HOWARTH,1,2,3 EM PENASCOZA,1 SM ABIMOSLEH1,2 1Discipline of Physiology, School of Medical Sciences, The University of Adelaide, Adelaide, Australia, 2Centre for Paediatric and Adolescent Gastroenterology, Children, Youth and Women’s Health Service, North Adelaide, Australia, 3School of Animal and Veterinary Sciences, The University of Adelaide, Adelaide, Australia Introduction: Non-steroidal anti-inflammatory drug (NSAID) ingestion frequently manifests as inflammation and ulcerating lesions lining the gastrointestinal tract, which may result in fatal sepsis. To date, there are no effective treatment options. Emu Oil (EO) is extracted from emu adipose tissue comprising a fatty acid profile of oleic, palmitic, linoleic and stearic acids. The remaining composition remains undefined, although natural antioxidants such as carotenoids, flavones, tocopherols and phospholipids have been implicated. We have previously demonstrated the anti-inflammatory properties of EO in a rat model of ulcerative colitis (Abimosleh et al., Dig Dis Sci, 2012) and chemotherapy-induced mucositis (Abimosleh et al., Exp Bio Med, 2013; in press).

3C). These results were further confirmed

in the partial hepatectomy model. CB2 mRNA expression was induced 48 and 72 hours after partial hepatectomy (Fig. 3D), and CB2−/− mice also showed a retarded regenerative response, as shown by western blot analysis and immunohistochemistry of PCNA expression (Fig. 3E) or bromodeoxyuridine staining (not shown). Altogether, these data indicate that CB2 receptors accelerate liver regeneration. Further experiments aimed at delineating the molecular mechanisms underlying the beneficial effect of CB2 receptors on hepatocyte survival and regeneration.24, 25 We first investigated the impact of CB2 receptor deficiency on hepatic expression of factors with known effects on hepatocyte survival and/or regeneration.24, 25 The induction of inducible nitric oxide synthase (iNOS), TNF-α, and IL-6 mRNA was attenuated in CCl4-treated CB2−/− RG7420 mice as compared to WT counterparts (Fig. 4A) whereas the induction profile

of monocyte chemoattractant protein-1 (MCP-1), IL-10, and Toll-like receptor 4 (TLR4) was similar in both groups (Fig. 4B). Following CCl4 administration, up-regulation of iNOS in hepatocytes is a compensatory protective pathway with respect to hepatocyte apoptosis.26-29 Given the impairment of iNOS induction in the liver of CB2−/− mice exposed to CCl4, we investigated whether an NO donor would attenuate the exacerbation of liver injury in these mice. Treatment with SIN-1 reduced the rate of TUNEL-positive hepatocytes in CCl4-exposed CB2−/− mice, whereas liver Caspase inhibitor injury was unchanged in CCl4-injected WT animals (Fig. 5A). However, SIN-1

did not significantly improved liver regeneration in WT mice (not shown) or in CB2−/− animals, although a trend to increase was noted in the latter group (P = 0.13; Fig. 5B). These results suggest that CB2 inactivation leads to defective induction of hepatic iNOS, thereby enhancing hepatocyte death following acute liver injury. In contrast, the impairment of liver regeneration found in CCl4-treated CB2−/− mice may result from additional mechanisms. IL-6 plays a major role in hepatocyte survival and regeneration.24, 25, 30 Given the impairment of IL-6 induction in the 上海皓元 liver of CCl4-treated CB2−/− mice, we explored whether defective liver regeneration would be restored by IL-6 administration. IL-6 did not affect TUNEL staining in CCl4-treated WT or CB2−/− mice at 24 hours (Fig. 6A). In contrast, IL-6 restored PCNA expression in CCl4-treated CB2−/− animals to 75% of its level in CCl4-treated WT animals (Fig. 6B). These findings suggest that IL-6 deficiency is a key event in the impairment of liver regeneration observed in CB2−/− animals. MMPs contribute to liver injury and regeneration. IL-6 has been shown to down-regulate hepatic MMP-2 activity following acute CCl4 administration.31 We therefore investigated whether CB2 receptors modulate hepatic MMP activity via an IL-6–dependent mechanism.

Furthermore, we used glutathione S-transferase pull-down, co-immunoprecipitation,

and selleck kinase inhibitor confocal microscopy to demonstrate that SOX1 could interact with β-catenin but not with the β-catenin/TCF complex. Moreover, restoration of the expression of SOX1 induces significant cellular senescence in Hep3B cells. Conclusion: Our data show that a developmental gene, SOX1, may function as a tumor suppressor by interfering with Wnt/β-catenin signaling in the development of HCC. (HEPATOLOGY 2012;56:2142–2153) The incidence and mortality of hepatocellular carcinoma (HCC) have been increasing rapidly worldwide in recent decades.1 The risk factors associated with hepatocarcinogenesis are numerous and include chronic hepatitis B or C viral infection, alcohol, aflatoxin B1, and others. However, the molecular mechanisms involved in the

development of HCC remain unclear. Recent studies have demonstrated that inactivation of tumor suppressor genes (TSGs) through promoter hypermethylation find more plays an essential role in carcinogenesis.2, 3 Furthermore, methylation profiles have been used as potential biomarkers for early diagnosis, prognostic prediction, and screening in HCC.4 Therefore, exploring the molecular mechanisms of the inactivation of TSGs involved in HCC development could improve the treatment of HCC in the future. The Wnt signaling pathway is comprehensively involved in cell differentiation, embryonic patterning, proliferation, and adult homeostasis.5 Stabilized β-catenin through nuclear translocation forms a complex with T cell factor/lymphocyte-enhanced factor (TCF/LEF) and triggers the transcription of Wnt target genes such as c-MYC and cyclin D1.6 Abnormal activation of Wnt signaling stemming from mutations MCE公司 in β-catenin, adenomatous polyposis coli (APC), or axins or downregulation of APC occurs in various human cancers.7 Moreover, increasing evidence proposes that aberrant activation of Wnt/β-catenin signaling is involved in the initiation and progression

of HCC.8 In addition to mutations in the components of Wnt signaling,9 promoter hypermethylation of Wnt-antagonists such as the secreted frizzled-related protein family, Dickkopf 3 and Wnt inhibitory factor-110, 11 also contribute to abnormal activation of this signaling in HCC. SRY (sex determining region Y)-box (SOX) family proteins contain a highly conserved high-mobility group DNA binding domain12 and play a role during embryonic and postnatal development.13 Furthermore, SOX2, SOX7, SOX9, and SOX17 have been demonstrated to be tumor suppressors in different types of cancers.14-17 However, some studies have shown that SOX1, SOX2, SOX3, and SOX9 possess oncogene functions.18-21 Until now, the role of the SOX family in cancer development has been unclear. Structurally related to TCF/LEFs, several members of the SOX family have been implied to repress β-catenin activity by either stimulating degradation of β-catenin or by an unknown mechanism.

e., bleeding, hematoma, infection, etc.) were observed and MG-132 purchase no elevation in the incidence of HCC was observed over a 192-week follow-up. In respect to short-term efficacy, the improvement in self-reported symptoms was

not different between the two groups. In respect to liver function at 1-4 weeks, the improvement in group A was superior to that in group B, as the improvement of ALB and TBIL levels and PT and MELD scores in group A were markedly superior to those in group B at 2-3 weeks after transplantation; however, ALT levels were not markedly changed. In respect to liver function at 1-48 weeks, the observed improvements were not maintained after 36 weeks. Furthermore, during the 192-week follow-up, results revealed no remarkable differences in the incidence of HCC or survival rate between the two groups. These finding

implied that autologous MMSC transplantation could not improve selleckchem the long-term prognosis of patients with liver failure caused by hepatitis B. Furthermore, in group A, no significant difference was observed in the incidence of HCC or survival rate at the different time points between patients with and without cirrhosis. Since cirrhosis is considered one of the most important risk factors for HCC and can lead to a high mortality for patients with hepatitis B,30, 31 our results provided evidence that autologous MMSC transplantation might exert protective effects for cirrhosis patients in regards to the occurrence of HCC and mortality. Based on the above results, we speculated that autologous MMSC transplantation was safe for patients with liver failure caused 上海皓元医药股份有限公司 by hepatitis B. Autologous MMSC transplantation had favorable short-term efficacy (from postoperative weeks 4 to 36) and played important roles in repair after acute liver injury as well as improved disease condition and mortality. Also, for patients with cirrhosis, autologous MMSC transplantation might exert better protective effects in regards to the occurrence of HCC and mortality, but could not markedly improve the long-term prognosis of these patients. In addition, the transfusion of MMSCs was

performed through the proper hepatic artery. However, it has been shown to be inappropriate to perform the transfusion through the hepatic artery,26 and transfusion through peripheral veins may achieve more favorable outcomes.12, 14 Furthermore, the limited number of MMSCs in the bone marrow from patients for transfusion32 and that the homing ability was difficult to increase are the main causes of the compromised efficacy of autologous MMSC transplantation, and this may be why our autologous MMSC transplantation did not achieve acceptable long-term effects on prognosis. In vitro proliferation of autologous MMSCs and multiple transplantations with MMSCs with high purity and high density may be the key factors for improving the efficacy of transplantation.
