OBJECTIVETo investigate the effects of culture supernatant of human amnion mesenchymal stem cells (hAMSCs-CS) on biological characteristics of human fibroblasts.

METHODS(1) hAMSCs were isolated from deprecated human fresh amnion tissue of placenta and then sub-cultured. The morphology of hAMSCs on culture day 3 and hAMSCs of the third passage were observed with inverted phase contrast microscope. (2) Two batches of hAMSCs of the third passage were obtained, then the expression of vimentin of cells was observed with immunofluorescence method, and the expression of cell surface marker CD90, CD73, CD105, and CD45 was detected by flow cytometer. (3) hAMSCs-CS of the third passage at culture hour 72 were collected, and the content of insulin-like growth factor Ⅰ (IGF-Ⅰ), vascular endothelial growth factor (VEGF), epidermal growth factor (EGF), and basic fibroblast growth factor (bFGF) were detected by enzyme-linked immunosorbent assay. (4) Human fibroblasts were isolated from deprecated human fresh prepuce tissue of circumcision and then sub-cultured. Human fibroblasts of the third passage were used in the following experiments. Cells were divided into blank control group and 10%, 30%, 50%, and 70% hAMSCs-CS groups according to the random number table (the same grouping method below), with 48 wells in each group. Cells in blank control group were cultured with DMEM/F12 medium containing 2% fetal bovine serum (FBS), while cells in the latter 4 groups were cultured with DMEM/F12 medium containing corresponding volume fraction of hAMSCs-CS and 2% FBS. The proliferation activity of cells was detected by cell counting kit 8 and microplate reader at culture hour 12, 24, 48, and 72, respectively, and corresponding volume fraction of hAMSCs-CS which causing the best proliferation activity of human fibroblasts was used in the following experiments. (5) Human fibroblasts were divided into blank control group and 50% hAMSCs-CS group and treated as in (4), with 4 wells in each group, at post scratch hour (PSH) 0 (immediately after scratch), 12, 24, 48, and 72, the migration distance of cells was observed and measured with inverted phase contrast microscope. (6) Human fibroblasts were grouped and treated as in (5), with 3 battles in each group, and apoptosis rate of cells was detected by flow cytometer. Data were processed with analysis of variance of factorial design, analysis of variance for repeated measurement, one-way analysis of variance, LSD test, and t test.

RESULTS(1) On culture day 3, most hAMSCs were in large form, and spindle-shaped with much prominences like fibroblasts or in flat polygonal shape. hAMSCs of the third passage were spindle-shaped. The expression of vimentin of hAMSCs of the third passage was strongly positive, and the expressions of surface markers CD90, CD73, and CD105 of the cells were positive, while the expression of CD45 of the cells was negative. (2) The content of IGF-Ⅰ, VEGF, EGF, and bFGF in hAMSCs-CS were respectively (11.7±1.0), (316±68), (6.1±0.4), and (1.49±0.05) pg/mL. (3) At culture hour 12-72, the proliferation activity of human fibroblasts in each hAMSCs-CS group was significantly higher than that in blank control group (with P values below 0.01), and the proliferation activity of human fibroblasts in 50% hAMSCs-CS group was the highest. (4) The width of scratch in two groups was nearly the same at PSH 0. The migration distance of cells in 50% hAMSCs-CS group was significantly longer than that in blank control group at PSH 12-72 (with P values below 0.01). (5) The apoptosis rate of human fibroblasts in blank control group was (16.2±2.4)%, which was significantly higher than that in 50% hAMSCs-CS group [(7.4±3.6)%, t=6.710, P<0.01].

CONCLUSIONShAMSCs-CS can promote proliferation and migration of human fibroblasts and inhibit the apoptosis of human fibroblasts.

In kidney, the role of cell proliferation, differentiation, apoptosis, inflammatory mediators and cytokines expression is closely related with cell signaling pathways, including tyrosine kinase pathway, transforming growth factor-beta/Smad pathway, Rho/Rho-associated coiled-coil forming protein kinase pathway, phosphoinositol pathway, cyclic nucleotide pathway, nuclear factor kappaB pathway and so on. Some Chinese herbs and their extracts, such as rhubarb and triptolide, as well as some Chinese herbal prescriptions, such as astragalus-angelica mixture and Chailing decoction, not only could ameliorate proliferation, differentiation and apoptosis of renal cell by regulating cell signaling pathways, but also could control target gene transcription, expression and its biological effects through inhibiting the phosphorylation of key signaling molecules.

OBJECTIVEThe three-dimensional (3D) structure of left atrial appendage (LAA) in atrial fibrillation patients were reconstructed by Mimics 3D imaging system, aiming at guiding for selection of both the size and location of the closure devices and making preliminary risk assessment of LAA closure with Watchman system.

METHODSInclusion criteria were: ten voluntary patients with both atrial fibrillation and indication for LAA closure aging from 40 to 85 years old with contraindication for oral anticoagulants or unwillingness to take long-term oral anticoagulation therapy from May to December 2014. 3D reconstruction of LAA was preoperatively made by Mimics 3D imaging system. With the Mimics 3D reconstruction model and the results of both transesophageal echocardiography (TEE) and LAA radiography, the size and location for the closure device were chosen. The devices were planted at the ostium of the LAA.

RESULTSTen atrial fibrillation patients were enrolled (average age: (66.3±11.9) years old) and all successfully implanted with the Watchman LAA closure devices. Nine of them were with non-valvular atrial fibrillation with average CHADS2-VAS score (3.2±1.7) and HAS-BLED score (2.7±1.6). The rest one was a valvular atrial fibrillation patient with the history of the percutaneous balloon mitral valvuloplasty (PBMV) without surgical indications of mitral valve replacement (MVR). There was no blood leakage around the device by regular postoperative TEE and LAA radiography examinations. There were no complications of bleeding, embolism, or stroke through both at peri-operative period and at 1 month follow-up post procedure.

CONCLUSIONPreoperative Mimics 3D reconstruction of LAA by Mimics 3D imaging system among atrial fibrillation patients provides essential information guiding the successful LAA closures.
