Cell therapy has a very promising potential for end-stage liver diseases (ESLD).Fetal liver stem/progenitor cells (FLSPCs) have advantages of safety,high survival and proliferation rates,and a small volume,all which make them ideal for liver disease stem cell therapy.During the early phase of our study,we applied a three-step separation method to enrich FLSPCs and obtained a separation efficiency similar to that of the flow-cell sorting method.Additionally,using a fulminant hepatic failure model in rats,we have demonstrated that FLSPCs can contribute to morphological and functional recovery of the liver.This manuscript will discuss how FLSPCs can be induced to accurately differentiate into hepatocytes and cholangiocytes and how FLSPCs maintain self-renewal.The Notch signaling plays a critical role in regulating the differentiation and self-renewal of many types of stem cells.Our previous findings have shown that the Notch signaling plays an important role in FLSPCs differentiation into hepatocytes.Therefore,the Notch signaling might be involved in the differentiation and self-renewal of FLSPCs.We conducted a study on the regulatory effects and relative molecular mechanisms of the Notch signaling on FLSPCs and found the corresponding interfering target,which might become an index for the clinical application of FLSPCs.

Objective To investigate early and midterm outcomes after minimally invasive1-stop or 2-stage MICSCABG and PCI hybrid surgery.Methods Between June 2011 and February 2015, 28 patients(19 males and 9 females) with multiple coronary artery disease underwent MICS-CABG and PCI hybrid surgery, 4 cases of which were1-stop hybrid surgery and 24 cases were 2-stage.All patients were followed up to major adverse events(recurrent angina, secondary myocardial infarction, congestive heart failure, serious arrhythmias, secondary bypass graft) as the end point event.Results All patients were no perioperative deaths, shock, infection and myocardial infarction.ICU stay time was(22.9 ± 12.5) h, hospital stay time was(6.75 ±2.10) days, intubation time was(21.1 ± 17.7) h.Perioperative1-stop and2-stages hybrid surgery had significant statistical differences in ICU stay time and intubation time[(41.8 ±32.9) h vs.(16.5 ± 8.5) h;(40.0 ± 34.2) h vs.(18.8 ± 8.5) h;P ＜ 0.05].Patients were followed up for 1-44 months, averaged (17.9 ± 12.8) months.The postoperative major adverse event rate was 7.14％, one patient died of cerebral hemorrhage after 6 months, and one patient underwent coronary angiography because angina.Conclusion l-stop or 2-stage MICS-CABG and PCI hybrid surgery provides a safe,effective and cosmetic revascularized method to patients with multiple coronary artery disease.Meanwhile,the procedure does not destroy the way of re-operation.The perioperative and early results of follow-up are satisfactory.

Objective To investigate the relationship between serum omega-3 polyunsaturated fatty acid (ω-3PUFA) and insulin resistance(IR) in patients with type 2 diabetes mellitus and non-alcoholic fatty liver disease (NAFLD). Methods This trial involved 51 patients of type 2 diabetes mellitus with NAFLD (G4 group), 50 patients of type 2 diabetes alone(G3 group), 45 patients of NAFLD alone (G2 group) and 42 healthy control subjects (G1 group). Serum ω-3PUFA profile was analyzed with capillary gas chromatography. Insulin resistance was assessed by homeostasis model assessment (HOMA-IR). ALT, AST, γ-glutamyltransferase(GGT) and serum lipids were measured. Results The levels of HOMA-IR were higher in G4 group than those in G3, G2 and G1 group(4. 90 ± 2. 54 vs 2. 38 ± 1.23, 2. 20 ± 1.15, 1.13± 0.42;P<0.05). The level of ALT, AST, GGT, TC, TG, LDL-C were higher in G4 group than those in G3, G2 and G1 group(P < 0. 05). The level of ω-3PUFA was signifieantly lower in G4 group than those in G3, G2 and G1 group(5.68 ±2.02 vs 7. 17 ±2. 38, 6.97±2.32, 10.08±2.76;P <0.05). ω-3PUFA cocentration was negatively correlated with HOMA-IR, TC, TG and LDL-C (r = -0.491, -0. 376, - 0. 462, - 0. 408, P < 0. 05). Conclusions Serum ω-3 PUFA is significantly decreased in patients with type 2 diabetes mellitus and NAFLD. Serum ω-3PUFA is negatively correlated with insulin resistance. ω-3PUEA plays a very important role in the development of diabetes mellitus and NAFLD.
