ObjectiveTo study the differentiation of adipose tissue-derived mesenchymal stem cells (ADMSCs) into cardiomyocytes in vitro. MethodsADMSCs were isolated and purified by the method of digesting and adhering to the culture plastis. The third generation of cells were determined with immunocytochemistry method and induced by 5-aza. On the 7th, 14th, 21st, 28th day after being induced, the surface antigen of myoblast cell and cardiac myocyte were determined, the expression of gene of GATA4 and Nkx2.5 were tested, and the content of atrial natriuretic polypeptide (ANP) assayed. ResultsImmunocytochemical staining showed CD44, CD13, CD105 positive, CD45, CD34, HLA-DR, factor Ⅷ negative. After being induced by 5-aza, the direction of cell arraying was gradually similar. The cells were stained positively for Desmin, α-Sarcomeric Actin, myosin heavy chain and Troponin T. The cells express GATA4 and Nkx2.5 and secrete ANP. ConclusionThere was mesenchymal stem cells in human adipose tissue. 5-aza may induce ADMSCs to differentiate into cardiomyocytes in vitro.

OBJECTIVETo explore the functional brain localization with magnetic resonance imaging (MRI) after acupuncturing the Yuan-Source and He-Sea acupoints of Stomach Meridian of Foot-Yangming (ST).

METHODSThe study was performed in 30 healthy volunteers who underwent acupuncture at Yuan-Source acupoint (Chongyang, ST42) and He-Sea acupoint (Zusanli, ST36) (ST group). Ten of these were also underwent acupuncture at the non-acupoints as the control group. Blood oxygenation level dependent functional MRI was performed.

RESULTSIn the ST group, signal increasing areas were demonstrated in bilateral superior temporal gyri (Broadmann 22), bilateral supramarginal gyri (Broadmann 40), bilateral cerebellar hemispheres, bilateral cingulate gyri and isthmus of cingulate gyri (Broadmann 32, 30), bilateral superior parietal lobules (Broadmann 7); signal decreasing areas were shown in bilateral orbital gyri (Broadmann 11), bilateral temporal pole (Broadmann 38), right inferior frontal gyrus (Broadmann 47) and right medial occipitotemporal gyrus (Broadmann 36). In the control group, signal increases areas were demonstrated in superior temporal gyri, precentral gyri, cingulate gyri, thalamus, insula and cerebellum. The size, signal intensity and number of increasing areas in control group are less than in ST group.

CONCLUSIONCombined acupuncture of Yuan-Source and He-Sea acupoints of ST can activate and decrease the multiple brain regions of "splanchnic brain" and thus reach a new functional balance to relieve pain.
