Objective:To compare the results of three kinds of glucometers and automatic biochemistry analyzer for the detection of blood glucose level of finger capillary and vein blood, and adopt linear regression to analyze their relationship.Methods: 204 patients with or without diabetes were enrolled in this study. Their finger capillary and vein blood were detected by three kinds of glucose meters and automatic biochemistry analyzer, respectively. And these data were analyzed by using linear regression and pair-t-test.Results: The comparative results revealed that the order of correlation between every glucose meters with automatic biochemistry analyzer was Accuchek higher than GT-1920 and GT-1920 higher than One Touch when the range of hematocrit (Hct) value was in 35.1%-51.6%. The correlation of Hct between every glucose meter and automatic biochemistry analyzer when the range of Hct was 25.0%-35.0% was significant higher than that when the range was 35.1%-51.6% (t=2.19,P<0.05). For finger capillary blood, the bias of One Touch was largest, while for vein blood, the bias of GT-1920 and One Touch were better. Besides, the detected results of blood glucose both of GT-1920 and One Touch were significantly higher than automatic biochemistry analyzer(t=2.34,P<0.05).Conclusion: There were better correlation between every glucose meter and automatic biochemistry analyzer, respectively, and the correlations between them can be effected by Hct. While there were still certainly difference between them.

BACKGROUND: Prostate cancer stem cell is an important reason for the invasion and recurrence of prostatic carcinoma. However, separation efficiency of prostate cancer stem cells is very low.OBJECTIVE: To explore the efficient method for isolating and identifying the prostate cancer stem cells from human prostatic carcinoma cell lines PC-3 and LNCap. METHODS: Prostate cancer cell lines PC-3 and LNCap were cultured in serum free medium (SFM) and serum supplemented medium (SSM), respectively. The percentage of prostate cancer stem cells from different medium was detected by flow cytometry through markers CD133 and CD44, and the properties of prostate cancer stem cells were preliminarily identified using inducing differentiation experiments.RESULTS AND CONCLUSION: PC-3 and LNCap formed sphere cells in SFM, which can be induced into adherent cells after culture in SSM. Higher percentage of CD44+/CD133+cells was obtained from LNCap cells (1.71%; 0.73%) than PC-3 cells (0.59%; 0.32%) in both SFM and SSM. The number of CD44+/CD133+ LNCap cells was more than PC-3 using both methods (P < 0.05), but the efficiency of SFM and SSM had no statistical significance (P > 0.05). However, the culture cycle was longer and number of obtained cells was less by SFM culture, directly influencing functional determination of prostate cancer stem cells. Compared with suspension culture method with SFM, SSM is more convenient and effective in isolating prostate cancer stem cells from LNCap cells.

Objective To Investigate the influence of high-intensity pulsed electromagnetic field (HIPEMF) on neural differentiation of neonatal rats neural stem cells in vitro.Methods Neural stem cells (NSCs) were isolated from the subventricular zone of 3-day-old neonatal rats and cultured with serum-free condition medium for 14 days.All the NSCs were then randomly classified into an experimental group which received the stimulation of HIPEMF (0.1 Hz,4 T,8 pulses) and a control group which received no special intervention.Differentiation of the culture was induced by addition of 10％ fetal bovine serum on the first day after intervention,the morphological changes of cells were observed under the microscope at different time points.The NSCs adhered to the wall and differentiated for seven days,the immunofluorescence was employed to observed and calculate the ratio of differentiated cells with astrocyte marker GFAP or neuronal markers TUJ1.RT-PCR and western blotting were used to measure the expression levels of the differentiated cells based on gene and protein levels,respectively.Results Immunofluorescence staining showed the number of TUJI positive cells in the experimental group(33.4％ ± 5.1％)was significantly more than the control group (26.5％ ± 7.0％),while the number of GFAP positive cells was decreased(23.9％ ± 5.0％) as compared with the control group(36.2％ ± 2.2％).RT-PCR showed that the TUJ1 mRNA expression levels in the experimental group was (1.682 ± 0.086) times of the control group.Western blot showed that the expression of TUJ1 (0.729 ±0.061) in the experimental group was higher than in the control group (0.590 ± 0.157),while the expression of GFAP in the experimental group (0.566 ± 0.056) was less than in the control group(1.034 ± 0.051).Conclusions HIPEMF facilitates differentiation of neural stem cells to neurons,at the cost of reducing astrocytic differentiation.

Objective To investigate the expression of DNA methyltransferase 3b (DNMT3B) in hepatocellular carcinoma (HCC) and its effect and mechanism on the proliferation,invasion and migration of HCC cells.Methods The expression of DNMT3B gene was detected by qRT-PCR in 46 cases of HCC tissues and corresponding adjacent tissues;the results and clinical pathological parameters were analyzed.SiRNA targeting DNMT3B was transfected into MHCC97-H cells by RNA interference (RNAi) technique.The mRNA and protein expression levels of related genes were detected by qRT-PCR and Western blot.The cell proliferation was measured by MTT assay,and the invasion and migration abilities were measured by Transwell assay.Results In 46 HCC patients,the expression of DNMT3B (73.91％) was significantly higher in HCC than in adjacent normal tissue.The high expression of DNMT3B gene was associated with histological type and tumor size of HCC (all P＜0.05).Inhibition of DNMT3B gene expression decreased proliferation,invasion and migration of MHCC97-H cells.Interference with DNMT3B gene increased the expressions of tumor suppressor genes RASSFA1,APC and MTSS1 at mRNA and protein levels.Conclusion DNMT3B is associated with the progression of HCC.It may inhibit the proliferation,invasion and migration of HCC cells by regulating the methylation of downstream tumor suppressor gene.
