Objective To investigate the efficacy of autologous peripheral hematopoietic stem cell transplantation in the treatment of adult dermatomyositis. Methods A 21-year-old patient with dermatomyositis received autologous peripheral hematopoietic stem cell transplantation and was followed up for 6 years. Autologous peripheral hematopoietic stem cells were mobilized by recombinant human granulocyte colony stimulating factor (rhG-CSF) before the transplantation, and the conditioning regimens consisted of cyclophosphamide,methylprednisolone and cyclosporin. Rabbit anti-human T lymphocyte immunoglobulin began to be applied on day 3 after retransfer of stem cells. The improvement in symptoms, physical signs and biochemical indicators was observed, and hematopoietic restructuration and immunity resurrection were evaluated after the transplantation. Results After the transplantation, skin eruption greatly improved and gradually subsided. The muscle force of extremities restored from level Ⅳ before transplantation to level Ⅴ. The level of creatine kinase declined sharply after transplantation, but gradually returned to previous level. Leucocyte count began to decrease on the day of retransfer, and returned to the normal level on day 8. Immune function remained normal before and after the transplantation. Conclusion Autologous peripheral hematopoietic stem cell transplantation is an alternative treatment for severe and refractory dermatomyositis.

Objectives To analyze the clinical and pathological characteristics of gastric submucosal tumors (GSMTs), and evaluate the safety and efficacy of endoscopic treatment for GSMTs. Methods 61 patients with GSMTs were selected from June 2014 to September 2012 by endoscopy and ultrasonography;they were all treated by endoscopic therapy; pathological examination was took in all removed tumors, the tumors which could be the gastric stromal tumor were furtherly examined by molecular biology technique of immunohistochemistry. Result In 61 cas-es, 39 cases are female patients, accounting for 63.93%;the tumors located at the stomach fund accounted for 52.46%(32/61), at the gastric corpus for 21.31%(13/61), at the gastric antrum for 11.48 %(7/61), at cardia for 14.75%(9/61); 10 cases were treated by Endoscopic submucosal dissection, 21 by endoscopic submucosal excavation, 27 by Endoscopic full-thickness resection, 3 by Submucosal tunnelling endoscopic resection; in all 61 cases, 2 were changed to laparoscopic treatment because one tumor was too big and broke the Serous and another was located at mucus Lake of gastric fund, 1 occurred postoperative bleeding and was treated by laparoscopy successfully, 1 oc-curred postoperative perforation and was treated by endoscopy successfully; after pathological and immunohisto-chemical analysis, 34 tumors were identified as gastric stromal tumor and all of them in risk classification were at very low risk, 11 were leiomyoma, 5 were lipoma, 3 were heterotopic pancreas, 5 were calcifying fibrous pseudotu-mor, 2 were inflammatory fibroid polyps, and 1 was angiomatous proliferation; gastric stromal tumor at gastric fundus account for 73.53 % (25/34), at gastric corpus for 11.76 % (4/34), at gastric antrum for 5.88 % (2/34) and at cardia for 8.82 %(3/34). Conclusion Most GSMTs are found in female and commonly lack of specific clinical symptoms;GMSTs are commonly located at gastric fund and most of them are gastric stromal tumors, vast majority of gastric stromal tumors in the risk classification are at very low risk;the endoscopic resection is a mini-invasive, safe and ef-fective treatment for GSMTs.

Objective To investigate the effects of intrathecal morphine remote preconditioning (MRPC) on protein-serine-threonine kinases-endothelial nitric oxide synthase (Akt/eNOS) signaling pathways and cardiac myocyte apoptosis in rats.Methods Male SD rats weighing 280-320 g were used in this study.A needle was inserted through a surgically created hole into the sub-dural space of spinal cord.Thirty-six rats in which intrathecal needle was successfully placed without complication were randomly divided into 3 groups (n =12 in each).In group Ⅰ sham operation was performed (Sham).In group Ⅱ myocardial I/R was produced (I/R).In group Ⅲ morphine was given intrathecally in 3 repeated doses of 1 μg/kg at 5 min intervals before ischemia (MRPC).Myocardial I/R was produced by occlusion of left anterior descending branch (LAD) of coronary artery for 30 min followed by 120 min reperfusion.The animals were then sacrificed and hearts removed for measurement of area at risk (AAR) and infarct size area (IS).IS/AAR ratio was calculated.Myocardial apoptosis was detected by TUNEL and apoptotic index (the number of apoptotic myocardial cells/the total number of myocardial cells) was calculated.The levels of Akt,phosphorylated Akt (p-Akt) and eNOS was determined by Western blot.Results The infarct size,myocardial cell apoptotic index and pAkt level were higher and eNOS level was significantly lower in I/R group than those in group Sham (P < 0.01).MRPC significantly reduced the infarct size and myocardial cell apoptotic index,and pAkt and eNOS level up-regulated in group RMPC compared with group I/R (P < 0.01).Conclusions Akt/eNOS signaling pathways probably participate in the protective effects of intrathecal morphine remote preconditioning against myocardial I/R injury and myocardial cell apoptosis in rats.
