Objective To assess the association of metabolic syndrome (MetS) and low-level high density lipoprotein-cholesterol (HDL-C) with the invasion of prostate cancer (PCa) in the patients after radical prostatectomy (RP). Methods We collected and analyzed the data of 232 PCa patients treated with RP for prospective multicenter clinical study.The MetS was assessed according to NCEP-ATP Ⅲ.Patients were divided into MetS group and non-MetS group.Locally advanced PCa was defined as a pT-stage≥3.ISUP Gleason grading system (GS) were used for pathological grading.Logistic regression analyses assessed the association of MetS and its components with pathological data. Results MetS was an independent risk factor for GS≥8 after RP.Low HDL-C level was associated with locally advanced PCa.The risks of adverse pathological features increased with the number of MetS components. Conclusion Low HDL-C level and 4 or more MetS components are associated with higher risk of adverse pathological features of PCa.

Objective@#To investigate the expressions of serum miRNA-126 (miR-126) and miRNA-30c (miR-30c) in patients with pancreatic cancer, and to analyze the relationship with the occurrence of pancreatic cancer as well as the diagnostic value.@*Methods@#A total of 110 patients with pancreatic cancer diagnosed at the 928th Hospital of the Joint Service Support Force of PLA from January 2014 to December 2018 were selected, and 110 healthy people were also selected as the control group. The expression levels of serum miR-126 and miR-30c of 110 patients and the healthy controls were detected by using real-time quantitative polymerase chain reaction (qRT-PCR), and their relationship with clinicopathological features of pancreatic cancer was analyzed.@*Results@#The levels of serum miR-126 and miR-30c in pancreatic cancer group were lower than those in the healthy control group (0.43±0.12 vs. 1.02±0.27, t = 19.394, P < 0.01; 0.52±0.17 vs. 1.04±0.31, t = 15.426, P < 0.01). There was a positive correlation between levels of serum miR-126 and miR-30c in patients with pancreatic cancer (r = 0.399, P < 0.01). Expression levels of serum miR-126 and miR-30c were not correlated with age, gender and body mass index (BMI) of pancreatic cancer patients (all P > 0.05), but related with tumor size, differentiation degree, TNM stage and lymph node metastasis (all P < 0.05). High expression levels of serum miR-126 and miR-30c were protective factors for pancreatic cancer (all P < 0.05), while smoking, drinking and gallstones were risk factors for pancreatic cancer (all P < 0.05). The area under the curve of combined detection of serum miR-126 and miR-30c for diagnosis of pancreatic cancer was 0.906, the sensitivity was 90.80%, and the specificity was 82.20%.@*Conclusions@#The expression levels of serum miR-126 and miR-30c in patients with pancreatic cancer are low. Both of them may be involved in the occurrence and development of pancreatic cancer, and may be used as early diagnostic markers of pancreatic cancer.

Objective To observe the effects of different collagenase digestions on isolating human umbilical cord mesenchymal stromal cells (MSC) from Wharton’s jelly, to exam their differentiation ability and to investigate their passage effect on the immune phenotype. Methods Human umbilical cord samples were digested by collagenaseⅠorⅡorⅣfor 4-18 hours then were passed through sieves . Cells were collected by centrifugation then inoculated in DMEM/F12 medium at concentration within range of 4.8×103-1×104/cm2 to compare the effect of different digestions on MSC. Von kossa staining and tetracycline fluorescence was used to label the osteogenic differentiation capacity of MSC. Also RT-PCR was employed to identify the differentiate capacity of MSC into myocardial-like cells. The immunophenotype of MSCs were detected by flow cytometry after subculture. Results Using collagenaseⅠdigestion, the number of MSCs isolated from human umbilical cord in Wharton’s jelly and their vitality were much higher while the period to show cell extension and primary culture time were shorter than those using collagenaseⅡorⅣdigestions. The analysis of surface marker revealed that the expression of positive markers include CD29, CD44, CD73, CD90 and CD105 did not change with passages while the negative markers such as CD31, CD34 and HLA-DR increased significantly with passages;Differential experiments induced in vitro show that human umbilical cord MSC in wharton’s jelly had the ability to differentiate into osteoblasts and myocardial-like cells. Con?clusion The human umbilical cord MSC in Wharton’s jelly was successfully isolated by collagenaseⅠdigestion. This meth?od was simple with a high success rate while cell loss and damage were minimum. This makes large-scale cultivation possi? ble. Negative markers increased with cell passages. This phenomenon revealed that MSC showed directional differentiation.

BACKGROUND:High-quality and efficient umbilical cord-derived mesenchymal stem cells could be obtained by establishing and improving the method to avoid fungal contamination and by effectively decreasing pol ution rate of isolated culture during umbilical cord col ection. OBJECTIVE:To explore the effects of amphotericin B on growth and differentiation potential of umbilical cord-derived mesenchymal stem cells. METHODS:Umbilical cord-derived mesenchymal stem cells were separated from healthy ful-termed delivery fetus using col agenase digestion method and treated with amphotericin B. Subsequently, umbilical cord-derived mesenchymal stem cells were amplified and cultured in vitro with MesenPRO RSTM medium. The third passage of umbilical cord-derived mesenchymal stem cells in logarithmic phase was obtained to analyze their morphology, proliferation and immunophenotype, and induced to differentiate into osteoblasts and adipocytes in vitro. RESULTS AND CONCLUSION:After treatment with amphotericin B, umbilical cord-derived mesenchymal stem cells were successful y isolated and cultured in vitro. Flow cytometry results revealed that human umbilical cord-derived mesenchymal stem cells strongly expressed CD44, CD105 and CD73, CD90, and negatively expressed HLA-DR, CD29, CD31, and CD34. Amphotericin B-treated human umbilical cord-derived mesenchymal stem cells can stil differentiate into adipocytes and osteoblasts in vitro.

BACKGROUND: In vitro culture condition and culture efficiency are different in reported umbilical cord-derived mesenchymal stem cells, and lacked of unified standards. Different derived mesenchymal stem cells have different biological properties. Therefore, it is very necessary to establish a simple and high-performance culture system for umbilical cord-derived mesenchymal stem cells. OBJECTIVE: To observe the growth state of human umbilical cord-derived mesenchymal stem cells in different culture systems in vitro and adenovirus infection efficiency. METHODS: Mesenchymal stem cells were separated from healthy full-termed delivery fetus using collagenase digestion method and purified by adherent culture. These cells were cultured and amplified in DMEM (low glucose), MesenPRO RS~(TM) Medium and STEMPRO~(R) MSC SFM in vitro. The 3-5 passage mesenchymal stem cells were infected by the Ad5-EGFP, Ad5/11-EGFP, Ad5/35-EGFP as multiplicity of infection (MOI)=1, 10, 100. Viral infection and green fluorescence expression were observed at post-infection 24, 56 and 72 hours using inverted fluorescence microscope. RESULTS AND CONCLUSION: The cell morphology in STEMPR~(R) MSC SFM was different from other two culture system and these cells were not easy to adherent after trypsin digestion. Cell doubling time in the MesenPRO RS~(TM) Medium was shorter than other two groups. Mesenchymal stem cells were infected by Ad5/35-EGFP with higher efficiency than other two kinds of adenovirus, but part of cells appeared apoptosis. The infection efficiency of Ad5/11-EGFP was highest. The fluorescence intensity was gradually increased with increased MOI.

Objective To compare the efficacy of different dose esomeprazole-based triplen therapies for Helicobacter pylori (Hp)eradication. Methods Two hundred and forty Hp-infected patients were randomly assigned to undergo high-dose (40 mg) or low-dose (20 mg) esomeprasole combined with clarithromycin (500 mg) and amoxicillin (1g) twice a day for one week. Hp eradication test was performed at 4 weeks after the end of treatment to evaluate the response to therapy. Results One hundred and fourteen patients were followed up in high-dose patients, and 104 were Hp eradication. One hundred and thirteen patients were followed up in low-dose patients, and 101 were Hp eradication. There was no significant difference in eradication rate of intention-to treat analysis and per protocol analysis between high-dose and low-dose patients [86.7%(104/120) vs 84.2% (101/120) and 91.2% (104/114) vs 89.4% (101/113), P>0.05]. There was no significant difference in the rate of adverse effect between high-dose and low-dose patients (8.3%(10/120)vs 6.7%(8/120), P>0.05). Conclusion It demonstrates that low-dose esomeprazole-based triple therapy has a similar Hp eradication rate compared with high-dose esomeprazole-based therapy in China.
