4. Combination of magnesium ion with mineralized collagen intervenes osteogenic differentiation of mouse preosteoblasts
Chinese Journal of Tissue Engineering Research 2020;24(22):3467-3473
BACKGROUND: Preliminary study has shown that the composite materials composed of magnesium-based materials and mineralized collagen have a good supporting effect on repairing the critical defects, which can improve the mechanical strength of mineralized collagen and premature collapse during bone healing to some extent. However, magnesium-based metals degrade fast in chloride-containing solutions (including human body fluids or plasma), and the effects of releasing magnesium ions on the proliferation and differentiation of osteoblasts are unknown. OBJECTIVVE: To investigate the effects of magnesium ion combined with mineralized collagen on osteogenic differentiation of mouse preosteoblasts in vitro. METHODS: Mineralized collagen extracts were prepared from complete medium with magnesium ion concentration of 0, 5, 10, and 20 mmol/L. Mouse preosteoblasts were cultured with four mineralized collagen extracts, respectively, which were divided into mineralized collagen group, and 5, 10 and 20 mmol/L Mg2++mineralized collagen groups. The mouse preosteoblasts cultured in complete medium were used as control group. The cell morphology, proliferation, apoptosis, intracellular microfilament actin, and the activity of alkaline phosphatase and expression level of the osteogenic gene Runx2 after osteogenic differentiation were detected. RESULTS AND CONCLUSION: (1) After 24 hours of culture, the cells in the mineralized collagen group, and 5 and 10 mmol/L Mg2++ mineralized collagen groups adhered well, which showed no significant difference from the blank control group, and the elongated spindle cells with many synapses linked to the adjacent cells were observed. The cells in the 20 mmol/L Mg2++mineralized collagen group showed obvious pyknosis. (2) After 1, 3 and 5 days of culture, the cell viability in the 10 mmol/L Mg2++mineralized collagen group was significantly higher than that in the other four groups (P < 0.05). There was no significant difference among mineralized collagen, 5 mmol/L Mg2++ mineralized collagen and blank control groups (P > 0.05). The cell viability in the 20 mmol/L Mg2++mineralized collagen group was significantly lower than that in the mineralized collagen group (P < 0.05). (3) After 3 days of culture, DAPI staining showed that 20 mmol/L Mg2++mineralized collagen group had obvious nuclear disintegration, the other four groups had no obvious nuclear disintegration. (4) After 24 hours of culture, phalloidin staining showed that except the blank control and 20 mmol/L Mg2++mineralized collagen groups, the other three groups showed completely extended cell structure, and clear actin microfilaments, especially the 10 mmol/L Mg2++mineralized collagen group. (5) After 7 days of osteogenic differentiation, except for 20 mmol/L Mg2++mineralized collagen group, the activity of alkaline phosphatase and the expression level of Runx2 gene in the other three groups were significantly higher than those in the blank control group (P < 0.05), and those in the 10 mmol/L Mg2++mineralized collagen group was significantly higher than those in the 5 mmol/L Mg2++mineralized collagen and mineralized collagen groups (P < 0.05). (6) These results suggest that the combination of magnesium ion with mineralized collagen should be applied with appropriate concentration range of magnesium ion (≤ 10 mmol/L).

Objective To observe the effects of modifiedDanshen Decoction on spermidine/spermine acetyltransferase (SSAT) /polyamine pathways of SD rats with IRI; To investigate its protective mechanism. Methods The model of IRI was established by ligating left anterior descending coronary artery for 30 min followed by reperfusion for 90 min. The SD rats were randomly divided into the control group, sham-operation group, model group and modifiedDanshen Decoction group, with 10 rats in each group. The myocardial infarction size was measured by using TTC staining. The contents of SSAT were measured by ELISA. The SSAT mRNA and SSAT protein expression level were detected with real-time fluorescent quantitative PCR method and Western blot, respectively. The contents of polyamines (putrescine, spermidine, spermine) in cardiac tissue were detected by HPLC. Results Compared with sham-operation group, the myocardial infarction size, the SSAT content, the SSAT mRNA and SSAT protein expression levels of model group increased significantly, the contents of polyamines decreased significantly, with statistical significance (P<0.01); Compared with model group, the myocardial infarction size of modifiedDanshen Decoction group was significantly reduced, while the SSAT content and SSAT mRNA and protein expression level decreased significantly, the contents of polyamines increased, with statistical significance (P<0.05, P<0.01).ConclusionModifiedDanshen Decoction can adjust the SSAT polyamine pathways and increase polyamine content in cardiomyocytes, and thus play a role of protection of myocardial ischemia-reperfusion injury.

AIM: To determine the concentration of escitalopram in human plasma by HPLC-MS/MS and investigate the pharmacokinetics of escitalopram. METH-ODS: The method involved protein precipitation with methanol. The chromatographic separation was achieved within 6.0 min by using methanol-water with 15 mmol·L-1 ammonium acetate-formic acid (72:28:O.1, v/v/v) as mobile phase and a Lichrospher CN 150 mm×4.6 mm analytical column. The analytes were detected using an electrospray ionization tandem mass spectrometry in SRM mode. Detection of the ions was performed by monitoring the transitions of m/z 325.0 to 234.0 for escitalopram and m/z 409.1 to 238.1 for amlodipine (intemal standard), respectively. RESULTS:The standard curve was linear ( r = 0. 999) over the concentration range of 0.20 - 50.00 ng· ml- 1. Accuracy and precision were below the acceptance limits of 15%. The recoveries of escitalopram ranged from 96.0% to 103.6%. The lower limit of quantification for escitalopram was 0.20 ng· ml-1 using 200 μl plasma sample.The pharmacokinetic parameters of escitalopram after a single oral dosing of escitalopram oxalate tablet (10 rog)to ten healthy male volunteers were achieved. The Cmax, Tmax, AUC0-t, AUC0-∞, t1/2 and Ke of escitalopram were 9.21±2.10 ng·ml-1 , 3.75±1.04 h, 514.6±152.3 ng·h·ml-1 ,540.5±162.3 ng·h·ml-1 , 34.06±7.71 h and 0.021±0.004 h-1,respectively. CONCLUSION:The determination of concentration of escitalopram in human plasma by HPLC-MS/MS method was repid, sensitive and reliable. It can be used for clinical pharmacokinetic study of escitalopram.
