UNLABELLEDOBJECTIVE To investigate the effect of Nepsilon-(carboxymethyl) lysine albumin (CMLs), a primary advanced glycation end products (AGEPs) isoform in diabetic body, on the function and angiogenesis of adipose tissue-derived stem cells (ADSCs) and the protective effect of Danhong Injection (DH). METHODS Human ADSCs were cultured and separated from human subcutaneous fatty tissue using enzymatic digestion and centrifugation. The morphology was observed using optical microscope and differentiation capacities assessed. Cells were exposed to 5 different interventions respectively for 24 h, i.e., PBS, 60 1 microg/mL BSA, 60 microg/mL CML-BSA, 100 microL/mL DH, and 60 micro./mL CML-BSA +100 microL/mL DH. Their effect on the proliferation, migration, apoptosis, and secretion were observed using WST-1 assay, Transwell assay, Annexin V-FITC/PI flow meter test reagent kit, human VEGF reagent kit, ELISA reagent kit, respectively. The effect on ADSCs angiogenesis was observed by in vitro angiogenesis test.

RESULTSCompared with the BSA group, the capacities of proliferation and migration could be significantly inhibited by CML-BSA, the apoptosis promoted, the secretion of VEGF reduced, and the angiogenesis of ADSCs weakened (P < 0.05). Compared with the blank control group, 100 microL/mL DH could significantly promote the proliferation and migration capacities of ADSCs, inhibit apoptosis of ADSCs, increase the secretion of VEGF, and improve the angiogenesis of ADSCs (P < 0.05). Compared with the CML-BSA group, the inhibition of CML-BSA on the proliferation and migration capacities of ADSCs could be significantly reversed, the promotion of CML-BSA on the apoptosis of ADSCs improved, the secretion of VEGF increased, and the angiogenesis of ADSCs elevated (P < 0.05).

CONCLUSIONclusion CMLs could significantly inhibit the proliferation and migration capacities of ADSCs, promote their apoptosis, and inhibit their angiogeneses, which could be improved by DH.

OBJECTIVETo explore the effects of soothing liver and invigorating spleen recipes on lipopolysaccharide(LPS) induced hepatocyte inflammation of rats and TLR4/p38MAPK signal pathway.

METHODThe hepatocytes of SD rats were cultured and identified in vitro. The medicated serum of soothing liver and invigorating spleen recipes was prepared. The hepatocytes were treated with soothing liver and invigorating spleen recipes. Then Interleukin-6 (IL-6) and tumor necrosis factor-α (TNF-α) expression in cultural supernatants were assayed by ELISA. The expressions of Toll-Like 4 (TLR4), p38 mitogen activated protein kinases (p38MAPK) and p-p38 mitogen-activated protein kinase (p-p38MAPK) were detected by Western blot.

RESULTThe rat medicated serum of soothing liver and invigorating spleen recipes was extracted for 2-3 mL. The purified rat hepatocytes were 1.5 x 10(8)-2.0 x 10(8). The cell viability was above 95% detected by Typan blue staining. The hepatocytes were identified by immumofluorescence assay. The detection of hepatocyte cultural supernatants: compared with that of the control group, IL-6 and TNF-α expression were increased in the LPS group (P < 0.01). While compared with that of the LPS group, the expressions of IL-6 and TNF-α were decreased after soothing liver and invigorating spleen recipes intervention (P < 0.01). The detection of hepatocyte proteins: compared with that of the control group, the protein expressions of p38MAPK, p-p38MAPK and TLR4 were all increased significantly in the LPS group (P < 0.01). Compared with that of the LPS group, the protein expressions of p38MAPK was decreased significantly in SB239063 group and it was also decreased in the soothing liver and invigorating spleen recipes group, but with no significant difference. Compared with that of the LPS group, p38MAPK expression was reduced significantly in the soothing liver and invigorating spleen recipes group and the SB239063 (p38MAPK pathway inhibitor) group (P < 0.01). TLR4 protein expression was decreased markedly in the soothing liver and invigorating spleen recipes group (P < 0.01) but had no difference between the SB239063 group and the LPS group.

CONCLUSIONThe soothing liver and invigorating spleen recipes may regulate hepatocyte inflammatory injury of rats through TLR4/p38MAPK signaling pathway.

The reversible covalent interaction between boronic acids and cis-diol-containing compounds provides unique affinity for recognition and separation of cis-diol-containing biomolecules such as glycoproteins and sugars. Herein, by using β-blockers and β-agonists as representative hydroxyethylamines, the interaction between phenylboronic acid and hydroxyethylamines was investigated through nuclear magnetic resonance ( NMR) and high performance liquid chromatography ( HPLC ) . The results showed that strong interaction between hydroxyethylamines and phenylboronic acid occurred at high pH value, while the interaction became much weaker and even disappeared at low pH value. This interaction was similar to boronate affinity interaction between boronic acids and cis-diol-containing compounds. However, unlike boronate affinity, the presence of an aprotic solvent disrupted the interaction. The above findings not only provided new insights for in-depth understanding boronate affinity interaction, but also paved the basis for the application of the interaction between boronic acid and hydroxyethylamines.

Methods Fresh aerial roots were harvested and were used as the experimental samples. Stereoscopy was used for the observation of macroscopic appearance of Ficus microcarpa Linn.f. and Ficus elastica Roxb. ex Hornem.,and the microscope was used for the examination of their microscopic features of the velamen surface, cross section of root tip, cross section and longitudinal section of the posterior root, and powder. Results The appearance characteristics of the two species were as follows:the number of aerial roots of Ficus microcarpa Linn. f. was more,and the diameter was smaller than that of Ficus elastica Roxb. ex Hornem. The root tips of Ficus microcarpa Linn. f. aerial roots were light yellow turning to yellow-white, covered with gray or yellowish-white lenticels;the root tips of Ficus elastica Roxb. ex Hornem. aerial roots were light yellow or yellow, covered with gray lenticels. Microscopic identification results of the two plants were as follows:the primary xylems of transverse section of root tips and posterior roots of Ficus microcarpa Linn.f. and Ficus elastica Roxb. ex Hornem. were different,the former being five to seven heptarch,and the latter being six to eleven heptarch. Both of the two species had non-articulated unbranched laticifers in their longitudinal section of posterior root, and the diameter of Ficus. elastica Roxb. ex Hornem. was slightly larger than that of Ficus microcarpa Linn. f.. The powder of Ficus microcarpa Linn. f. was red brown,with spiral and pitted vessels;Ficus elastica Roxb. ex Hornem. was yellow brown,with single small and large pitted vessels,and the color of its fiber was shallow or nearly colorless or even transparent, with lines of cluster crystal. Conclusion The results will provide evidence for the identification , exploitation and utilization of Ficus microcarpa Linn . f . and Ficus elastica Roxb. ex Hornem.

Patients with myelodysplastic syndromes (MDS) become dependent on blood transfusions and develop into transfusional iron overload, which is exacerbated by increased absorption of dietary iron in response to ineffective erythropoiesis. However, it is uncertain whether there is an association among iron accumulation, clinical complications, and decreased likelihood of survival in MDS patients. Thereby our current understanding of the effects of transfusion dependency and iron overload in MDS are discussed. Particular emphasis should be placed on further characterizing the role of redox-active forms of labile iron and oxidative stress in iron overload, decreased life expectancy and increased risk of leukemic transformation in MDS patients with iron overload.
