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.

Background:The diagnostic accuracy of APRI and FIB-4 for liver fibrosis in patients with chronic hepatitis B is nothigh,especially for significant liver fibrosis (F≥2). Noninvasive diagnosis for liver fibrosis has become a research hotspot;and the diagnostic value of APRI combined with FIB-4 is not clear. Aims:To investigate the diagnostic value ofAPRI combined with FIB-4 for significant liver fibrosis in patients with chronic hepatitis B. Methods:A total of 171patients with chronic hepatitis B from January 2011 to October 2016 at General Hospital of Xinjiang Military Region wereenrolled. Liver biochemical indices,routine blood test and liver biopsy pathology were performed. APRI and FIB-4 werecalculated,ROC curve was drawn,and cutoff value of APRI and FIB-4 for diagnosing significant liver fibrosis wasdetermined,and mode of APRI combined with FIB-4 for diagnosing significant liver fibrosis was established. Results:Withthe increase in degree of liver fibrosis,APRI and FIB-4 were gradually increased (P < 0. 05). Area under ROC curve(AUC)for APRI and FIB-4 were 0. 812 and 0. 770,respectively. The sensitivity of FIB-4 for diagnosing significant liverfibrosis was higher than that of APRI. Sensitivity,specificity,negative predictive value,positive predictive value,andaccuracy of APRI combined with FIB-4 for diagnosing significant liver fibrosis were superior to APRI or FIB-4 used alone;and the specificity,accuracy of mode 2 were superior to mode 1. Conclusions:APRI combined with FIB-4 can increasethe accuracy for diagnosing significant liver fibrosis.

Objective To optimize the concentration of polyethylene glycol (PEG) for the growth of Chlamydia trachomatis (Ct) reference strains D-UW-5/Cx and E-UW-5/Cx,and to evaluate the effects of PEG on the sensitivity of Ct to 4 common antibiotics.Methods After the inoculation of Ct standard strains (D-UW-5/Cx and E-UW-5/Cx) into McCoy cell monolayer,different concentrations of PEG were added into the culture medium followed by centrifugation.After 2 hours of incubation at 37 ℃,the inoculum was removed and a complete culture medium containing 1 μg/mL cycloheximide was added followed by another 48-hour culture.Subsequently,the culture was fixed and subjected to iodine staining for the calculation of Ct inclusions and optimization of PEG for the growth of Ct.Some Ct standard strains were used to infect McCoy cells,with PEG (0.7%,wt/vol) added to the culture medium after inoculation and before centrifugation process,and when the infection rate reached higher than 90%,a microdilution method was utilized to evaluate the minimal inhibitory concentration (MIC) of 4 antibiotics,including azithromycin,minocyline,moxifloxacin and doxycycline.Thirty-one clinical specimens,which had been confirmed to be positive for Ct serovar D or E strain,were inoculated into McCoy cell monolayer for the passage of Ct with or without the presence of 0.7% PEG.Results The optimal concentration of PEG was 0.7% for the growth of Ct,and this concentration of PEG could increase the number of inclusion bodies of Ct serovar E by 3.44 folds,and that of Ct serovar D by 3.56 folds.In vitro,the MICs of the 4 antibiotics were consistent between PEG-treated and untreated Ct reference strains.Moreover,PEG notably increased the quantity of inclusion bodies of Ct serovar E or D from clinical specimens after passages.Conclusions PEG (0.7%) can enhance the growth of Ct serovar D and E,but has no obvious influence on antimicrobial susceptibility of Ct.

ObjectiveTo detect the changes of heat shock protein 60 (HSP60) during the subcultures of standard and clinical strains of Chlamydia trachomatis(Ct),and to determine if the absence of chlamydial inclusions is associated with the persistent infection of Ct.MethodsA total of 40 Ct strains isolated by cell culture from patients were included in this study and classified into 2 groups according to whether inclusions appeared after initial culture.Reverse transcription PCR was conducted to quantify the levels of HSP60 in specimens containing Ct after 1-4 subcuhures.Chi-squared test was performed to analyze the relationship between the levels of HSP60 and treatment outcomes of patients.ResultsThe levels of HSP60 in clinical specimens containing Ct serovar E were significantly higher in subcultures prior to the appearance of inclusions than in subcultures with the appearance of inclusions(P < 0.05).The ratio of HSP60:16S rRNA mRNA expression after the first,second,third,fourth passage was 0.38 ± 0.06,0.39 ± 0.03,0.38 ± 0.04 and 0.39 ±0.03 respectively in 18 specimens with inclusions appearing after the initial culture,1.18 ± 0.10,0.28 ± 0.06,0.30 ± 0.03 and 0.29 ± 0.05 respectively in 12 specimens with inclusions appearing after the second culture,1.20 ± 0.04,1.20 ± 0.04,0.28 ± 0.04 and 0.28 ± 0.05 in 10 specimens with inclusions appearing after the third culture.Whether inclusions appeared after the initial culture was associated with the treatment outcome of patients.Inclusions were undetected after the initial culture in 16 of 20 specimens from patients with poor response to treatment,but observed in 14 of 20 specimens from patients who tested negative for Ct after one course of treatment.Conclusions It is implicated that no inclusions form after the initial culture in 80% of specimens from patients experiencing treatment failure.The Ct strains whose inclusions do not form after passages may be in a persistent state,and the expression of HSP60 is high in these strains.Specimens should be subjected to at least 3 blind passages to avoid missed diagnosis of Ct infection.
