Effects of acupuncture-drug compound anesthesia on perioperative inflammatory factors in patients undergoing cardiac surgery / 中国针灸

<p><b>OBJECTIVE</b>To explore the effect of acupuncture-drug compound anesthesia on immune function in patients with extracorporeal circulation undergoing cardiac surgery.</p><p><b>METHODS</b>Thirty cases undergoing cardiac surgery which included atrial septal defect neoplasty, ventricular septal defect neoplasty, mitral valve replacement and pulmonary valve coarctotomy were randomly divided into group A and group B, 15 cases in each group. Group A was given general anesthesia plus acupuncture at Neiguan (PC 6), Lieque (LU 7) and Yunmen (LU 2), and group B was given simple general anesthesia. Tumor necrosis factor-alpha (TNF-alpha), interleukin-2 (IL-2) and interleukin-10 (IL-10) levels before and after surgery were compared.</p><p><b>RESULTS</b>The level of TNF-alpha was increased and the levels of IL-2 and IL-10 in the serum were decreased in both groups after extracorporeal circulation for 2 h and 24 h, and the ranges of all changes were more less in group A (all P < 0.05).</p><p><b>CONCLUSION</b>Compared with simple general anesthesia, acupuncture-drug compound anesthesia can improve immune suppression partially in the perioperative periods under the same conditions of controlling anesthesia degree.</p>

Influence of mesenchymal stem cells implantation on ventricular remodeling and heart function after acute myocardial infarcion / 上海第二医科大学学报

Objective To study the influence of mesenchymal stem cells(MSCs) implantation on ventricular remodeling and heart function after myocardial infarcion. Methods Bone marrow was aspirated from Gui-zhou Xiang swines.After being isolated,cultured and co-cultured with 5-azacytidine,either autologous MSCs(experiment group) or a comparable volume of physiologic saline(control group) were injected into the infarcted myocardium.Three and six weeks later,echocardiographic measurement was performed to assess the myocardial structure and heart function,and single photon emission computed tomography(SPECT) was employed for myocardial imaging.Implanted stem cells were detected by the anti-Brdv antibody DAB with HE staining. Results Left ventricular ejection fraction(EF),fractional shortening and wall thickening were higher in experiment group than control group.The thickness of the ventricular wall and septum was found increased while the left ventricular chamber size was smaller in experiment group.It was indicated by SPECT that three and six weeks after implantation,there was obvious image defect in control group while in experiment group there were some imaging areas in the infarcted area.Brdv-labelled cells were observed in the central part of and around the infarcted area.Conclusion Implantation of MSCs into the infarcted myocardium is believed to attenuate the remodeling process,inhibit the extent of wall thinning and dilatation of the ventricular chamber.MSCs implantation may also improve the contractile ability of the myocardium and heart function.
