At present, the main therapy for chronic renal failure (CRF) is dialysis and renal transplantation, but neither obtains satisfactory results. Human umbilical cord mesenchymal stem cells (huMSCs) are isolated from the fetal umbilical cord which has a high self-renewal and multi-directional differentiation potential. Icariin (ICA), a kidney-tonifying Chinese Medicine can enhance the multipotency of huMSCs. Therefore, this work seeks to employ the use of ICA-treated huMSCs for the treatment of chronic renal failure. Blood urea nitrogen and creatinine (Cr) analyses showed amelioration of functional parameters in ICA-treated huMSCs for the treatment of CRF rats at 3, 7, and 14 days after transplantation. ICA-treated huMSCs can obviously increase the number of cells in injured renal tissues at 3, 7, and 14 days after transplantation by optical molecular imaging system. Hematoxylin-eosin staining demonstrated that ICA-treated huMSCs reduced the levels of fibrosis in CRF rats at 14 days after transplantation. Superoxide dismutase and Malondialdehyde analyses showed that ICA-treated huMSCs reduced the oxidative damage in CRF rats. Moreover, transplantation with ICA-treated huMSCs decreased inflammatory responses, promoted the expression of growth factors, and protected injured renal tissues. Taken together, our findings suggest that ICA-treated huMSCs could improve the kidney function in CRF rats. © 2017 Springer Science+Business Media New York

Objective: To screen serum biomarkers of silica-exposed population for early diagnosis by liquid-chip time of flight mass spectrometry, and identify some associated functions of the markers. Methods: In addition to 30 healthy donors without silica-exposed history chosen as control, All the 85 subjects diagnosed as varied phase of silicosis according to national diagnostic standard (GBZ70-2002) of pneumonoconiosis without complications were recruited and taken blood to get serum. Short peptides purified by Dynabeads RPC18, were detected and their amino acid sequences determined using matrix-assisted laser desorption ionization-time-of-flight mass spectrometry (MALDI-TOF-MS). Effects of the identified peptides on Human embryonic lung fibroblasts (MRC-5) were tested using synthesized peptides. Results: A total of 5 peaks (P<0.01) were detected between healthy donors and silica-exposed population, in which the expressions of 5081 Da and 5066 Da are up-regulated while the expressions of 3954 Da, 2021 Da and 1777 Da are down-regulated. 2021 Da and 1777 Da peaks were selected for MALDI-TOF-TOF-MS, the amino acid sequences of the two peaks identified were both a fragment of complement C3 called complement C3f. The level of C3f was related to silicosis activity. The synthesized peptides of C3f inhibited proliferation of I, III collagen and TGF-β1 of MRC-5. Conclusion: This analysis in our study revealed C3f in serum of silica-exposed population may play an important position. Investigation of C3f may be a useful tool for the diagnosis and evaluation of disease activity in silicosis. © 2017, E-Century Publishing Corporation. All rights reserved.

A novel label-free method based on breathing-induced vapor condensation was developed for detection of genetic point mutation. The dew-inspired detection was realized by integration of target-induced DNA ligation with rolling circle amplification (RCA). The vapor condensation induced by breathing transduced the RCA-amplified variances in DNA contents into visible contrast. The image could be recorded by a cell phone for further or even remote analysis. This green assay offers a naked-eye-reading method potentially applied for point-of-care liver cancer diagnosis in resource-limited regions.

To determine the role of serum procalcitonin (PCT) and C-reactive protein (CRP) in predicting spontaneous bacterial peritonitis (SBP) in patients with advanced liver cirrhosis.A total of 88 patients with advanced liver cirrhosis were enrolled for this study, which included 40 cases with SBP and 48 cases with CNNA. Bacterial cultures, ascitic fluid (AF) leukocyte, C-reactive protein (CRP) and serum PCT measurements were carried out prior to the use of antibiotics. Receiver operating characteristic (ROC) curves were used to evaluate the diagnostic performance of procalcitonin levels.Serum PCT levels in advanced liver cirrhotic patients with SBP were significantly higher than those with CNNA. We used PCT 0.78 ng/mL as optimal cutoff value to diagnose SBP, for which the sensitivity and specificity was 77.5% and 60.4%. The area under the curve (AUC) was 0.706 (95% confidence interval: 0.576-0.798). The PCT level was significantly correlated with the AF WBC count (rs=0.404, P<0.01). However, there was no significant difference between SBP and CNNA patients in serum CRP levels.According to our findings, serum PCT levels seem to provide an early diagnostic accuracy in advanced liver cirrhotic patients with SBP.

AIM: To study the diagnostic value of controlled attenuation parameter (CAP), evaluated by transient elastography, for liver steatosis in patients with chronic hepatitis B (CHB).METHODS: Eighty-eight patients with CHB were enrolled in this study. All of the patients were subjected to transient elastography to determine CAP. These patients also underwent liver biopsy in the same period. Using liver biopsy as a reference, we determined receiver operating characteristic (ROC) curves for different endpoints. Areas under the ROC curves (AUCs) were used to evaluate the diagnostic importance of CAP for liver steatosis in patients with CHB.RESULTS: A positive correlation was observed between the AUCs of CAP and liver pathological stage (r = 0.582, P < 0.05). CAP was not correlated with inflammation degree and fibrosis degree (r = -0.025, P < 0.05; r = 0. 068, P < 0.05). The mean CAP value at S0 was 209.59 ± 41.25 dB/m, 223.84 ± 35.28 dB/m at S1, 274.17 ± 43.69 dB/m at S2, and 312.50 ± 25.44 dB/m at S3. CAP values among S0, S1, S2, and S3 were significantly different (F = 17.79, P < 0.01). The AUC values for CAP were 0.711 (0.592-0.870), 0.868 (0.748-0.989), and 0.974 (0.922-1.026) for S1, S2, and S3, respectively. The optimal cut-off values were 219.5, 230.0, and 283.5 dB/m.CONCLUSION: CAP is a novel tool that can be used to assess the degree of steatosis. © 2014 Baishideng Publishing Group Inc.

Chronic hepatitis B (CHB) virus infection can cause persistent hepatic inflammation and cirrhosis, which may lead to hepatocellular carcinoma (HCC). CHB is considered the dominant cause of HCC in Asia because of the endemic status of hepatitis B virus (HBV) infection. A persistently high viral load, long duration of infection, and cirrhosis are the major risk factors for developing HCC in CHB patients. Antiviral therapies using interferon (IFN) and nucleos(t)ide analogues (NAs) could suppress viral replication, reduce liver injury, and preserve liver function, thereby lowering the risk of developing HCC. Recurrence of HCC after therapy is closely related to high levels of HBV DNA at the initial stage. Western studies have found that persistent antiviral treatments on CHB patients could not only reduce their risk of developing HCC, but also prevent or delay HCC recurrence after liver transplantation, hepatic resection, or radiation therapies. This review will focus on Asian clinical studies, where there is a higher prevalence of CHB and HCC. The outcomes of antiviral therapies on HCC in these Asian studies were compared to those in the Western studies. © 2015, Discovery Medicine.

Hepatic encephalopathy (HE) is a severe neuropsychiatric syndrome that most commonly occurs in decompensated liver cirrhosis and incorporates a spectrum of manifestations that ranges from mild cognitive impairment to coma. Although the etiology of HE is not completely understood, it is believed that multiple underlying mechanisms are involved in the pathogenesis of HE, and one of the main factors is thought to be ammonia; however, the ammonia hypothesis in the pathogenesis of HE is incomplete. Recently, it has been increasingly demonstrated that inflammation, including systemic inflammation, neuroinflammation and endotoxemia, acts in concert with ammonia in the pathogenesis of HE in cirrhotic patients. Meanwhile, a good number of studies have found that current therapies for HE, such as lactulose, rifaximin, probiotics and the molecular adsorbent recirculating system, could inhibit different types of inflammation, thereby improving the neuropsychiatric manifestations and preventing the progression of HE in cirrhotic patients. The antiinflammatory effects of these current therapies provide a novel therapeutic approach for cirrhotic patients with HE. The purpose of this review is to describe the inflammatory mechanisms behind the etiology of HE in cirrhosis and discuss the current therapies that target the inflammatory pathogenesis of HE. © 2015 Baishideng Publishing Group Inc.

Hepatic fibrosis is characterized by progressive inflammation and deposition of extracellular matrix components. Several recent studies have demonstrated that the rennin-angiotensin system (RAS) plays a key role in hepatic fibrosis. In this review, we provide a comprehensive update of the role of the RAS in the pathogenesis of hepatic fibrosis. We will discuss the profibrotic mechanisms activated by the RAS. Studies that have utilized angiotensin receptor blockers and angiotensin-converting enzyme inhibitors to modulate the RAS to ameliorate hepatic fibrosis will also be discussed. © 2013 Baishideng.

Background: We devised this study to quantify the effect of age on the consumption of cisatracurium under general anaesthesia, using a computer controlled closed loop infusion system. We further investigated this effect on, sufentanil and propofol consumption.Methods: 74 patients of physical status I and II, requiring general anaesthesia for elective abdominal surgery, were assigned to three groups. Patients in group 1 were aged from 20 to 45, group 2 were from 46 to 64, and group 3 above 65 years old. General Anesthesia was maintained with propofol and muscle paralysis was maintained using a closed-loop computer controlled infusion of cisatracurium. For analgesia, intermittent bolus of sufentanil 10 μg was given.Results: Cisatracurium consumption in group 1, 2 and 3 were 1.8 ± 0.3, 1.6 ± 0.4 and 1.3 ± 0.4 μg/kg/min respectively. There was significant difference of cisatracurium consumption between group 1 and 3 (P = 0.002), and the consumption of cisatracurium in group 3 was less as compared with group 2 (P = 0.04). The average recovery index of patients in group 1, 2 and 3 were 8.8 ± 2.6, 11.5 ± 2.9 and 12.7 ± 2.5 minutes respectively. There were difference between group 1 and 2 (P = 0.02). As compared with group 1, the recovery index was still longer in group 3 (P = 0.001). Patients in group 1, 2 and 3 consumed an average sufentanil 0.4 ± 0.1, 0.4 ± 0.1 and 0.3 ± 0.1 μg/kg/hr, respectively. There were statistical significant between group 1 and 3 (P < 0.0001), and the same trend was found between group 2 and 3 (P = 0.03). The Consumption of propofol in group 1, 2 and 3 were 5.1 ± 0.4, 4.3 ± 0.6 and 3.1 ± 0.5 mg/kg/hr. The difference in the propofol consumption was found statistically significant when comparing between any two groups.Conclusion: We concluded that the sensitivity of anesthetic agents increased with age. Less medication was required to achieve a desirable effect in older patients specially those above 65 years of age, and the drug effect was prolonged.Trial registration: ClinicalTrials.gov Identifier: NCT01785446. © 2014 Joomye et al.; licensee BioMed Central Ltd.
