Male factors in repeated spontaneous abortion / 中华男科学杂志

Repeated spontaneous abortion (RSA), with very complicated pathogenesis, has an incidence of about 0.5% 2.0%. As for the paternal part which provides half of the genes for the embryo, current studies mainly focus on the genes of somatic cells or germ cells. Chromosome abnormality of somatic cells, chromosome disorder of sperm, defects in sperm quality, genetic mutation, senility, infection and any other paternal gene abnormalities that affect the embryo would induce RSA. This paper presents an update on the above mentioned paternal factors which might result in RSA.

Human umbilical cord-derived endothelial progenitor cells promote growth cytokines-mediated neorevascularization in rat myocardial infarction / 中华医学杂志(英文版)

<p><b>BACKGROUND</b>Cell-based vascular therapies of endothelial progenitor cells (EPCs) mediated neovascularization is still a novel but promising approach for the treatment of ischemic disease. The present study was designed to investigate the therapeutic potentials of human umbilical cord blood-derived EPCs (hUCB-EPCs) in rat with acute myocardial infarction.</p><p><b>METHODS</b>Human umbilical cord blood (hUCB) mononuclear cells were isolated using density gradient centrifugation from the fresh human umbilical cord in healthy delivery woman, and cultured in M199 medium for 7 days. The EPCs were identified by double-positive staining with 1, 1'-dioctadecyl-3, 3, 3', 3'-tetramethylindocarbocyanine percholorate-labeled acetylated low-density lipoprotein (Dil-Ac-LDL) and fluorescein isothiocyanate-conjugated Ulex europaeus lectin (FITC-UEA-l). The rat acute myocardial infarction model was established by the ligation of the left anterior descending artery. The hUCB-EPCs were intramyocardially injected into the peri-infarct area. Four weeks later, left ventricular function was assessed by a pressure-volume catheter. The average capillary density (CAD) was evaluated by anti-VIII immunohistochemistry staining to reflect the development of neovascularization at the peri-infarct area. The graft cells were identified by double immunofluorescence staining with human nuclear antigen (HNA) and CD31 antibody, representing human origin of EPCs and vascular endothelium, respectively. Expressions of cytokines, proliferating cell nuclear angigen (PCNA), platelet endothelial cell adhesion molecule (PECAM) and vascular endothelial growth factor (VEGF) were detected to investigate the underlying mechanisms of cell differentiation and revascularization.</p><p><b>RESULTS</b>The donor EPCs were detectable and integrated into the host myocardium as confirmed by double-positive immunofluorescence staining with HNA and CD31. And the anti-VIII staining demonstrated a higher degree of microvessel formation in EPCs transplanted rats, associated with a significant improvement of global heart function in terms of the increase of left ventricular end-systolic pressure (LVESP), +dp/dtmax and -dp/dtmax as well as the decrease of LVEDP in rats with EPCs therapy comparing to the control rats (P < 0.05). Moreover, the expression of the rat PCNA mRNA and PECAM were both enhanced in the EPCs group compared with that of the control group.</p><p><b>CONCLUSIONS</b>The human umbilical cord blood-derived EPCs could incorporate into new-born capillaries in rat myocardium, induce revascularization and improve the proliferation activity in the peri-infarct area, resulting in the improvement of global heart function. This may indicate a promising stem cell resource in cell-based therapy for ischaemic diseases.</p>

8-(N,N-diethylamino)-n-octyl-3,4,5-trimethoxybenzoate inhibited the reduction of cerebral blood flow evoked by 5-HT and KCl in rats / 药学学报

<p><b>AIM</b>To investigate the impact of 8-(N,N-diethylamino)-n-octyl-3,4,5-trimethoxybenzoate (TMB-8) on the change of cerebral blood flow(CBF) induced by 5-HT or KCl in rats.</p><p><b>METHODS</b>The CBF in rats was measured by a Laser-Doppler flowmeter. The cranial window field was superfused with artificial cerebral spinal fluid containing TMB-8, 5-HT or KCl.</p><p><b>RESULTS</b>12.5, 25 and 50 mumol.L-1 TMB-8 showed no significant effect on rest CBF in rats. 12.5, 25 and 50 mumol.L-1 TMB-8 apparently inhibited the decline of CBF evoked by 1 or 2 mumol.L-1 5-HT. When persistent reduction of CBF were evoked by 1 mumol.L-1 5-HT, TMB-8 markedly increased the CBF in a concentration-dependent manner. The reduction of CBF induced by 20 or 40 mmol.L-1 KCl was also suppressed by 12.5, 25 and 50 mumol.L-1 TMB-8. While persistent reduction of CBF was evoked by 20 mmol.L-1 KCl. TMB-8 markedly increased the CBF in a concentration-dependent manner.</p><p><b>CONCLUSION</b>These results indicate that TMB-8 is effective in preventing and treating the reduction of CBF induced by 5-HT or KCl, and improved the supply of blood in rat brain during ischemia.</p>
