Objective To establish a method of cultivation and purification of dendritic cells(DCs) from mouse bone marrow and spleen in vitro and provide experimental material and establish basis for the study of immunological tolerance.Methods Extracted the ICR mice spleen lymphocytes and bone marrow cells under sterile conditions,and cultured DCs in co-induced of recombinant granulocyte-macrophage colony-stimulating factor(GM-CSF) and interleukin4(IL-4).Then,the changes of DC morphology were observed under light microscopy and CD80,CD86 expression levels were detected with flow cytometry.Results bone marrow cells appeared irregular and formed dendritic processes after 3 days cultured with stimulating factor in vitro which showed the typical morphology of dendritic cells,and costimulatory molecules(CD80,CD86) were low expression on the cellular suface.Conclusion Compared with the spleen cells,bone marrow cells are not only rich in DC precursor cells but also induced into DCs with a short time.

To study the role of CD4 + CD25 + Treg cells in anti-graft rejection response and potential value in application of lung transplatation, we established mice trachea allograft transplant model and sort CD4 + CD25 + Treg cells from mice spleen lymphocytes by MACS. FCM assays were done to analyze the ratio of marker protein, Foxp3, expression in CD4 + CD25 + Treg cells. Alveolar cells were used as a non-specific antigen to activate iDCs into mDCs, and cocultureed with CD4 + CD25 + Treg cells to activate Treg cells. The activated Treg cells were inject into mice with trachea allograft transplantation to reduce rejection response. The allografts were extracted and done pathological examination with H&E staining. The purity of CD4 + CD25 + Treg cells were over 80% and specifically express Foxp3, the organizational structure of implanted trachea showed that the tracheal structure was intact. Our research imply that CD4 + CD25 + Treg cells play an essential role in reducing rejection, and lay the foundation for reject anti-graft response in clinical application.
Objective To analyze the effect of T2~T3 sympathicotomy in the treatment of primary palmar hyperhidrosis.Method Total 25 patients with primary palmar hyperhidrosis,including 12 males and 13 females,with the average age of 30.7 years,underwent T2~T3 sympathicotomy,in which the sympathetic chains were transected at the level of the third ribs.Results Monitoring the skin temperature of both palm.The skin temperatures of the right palm were(32.0±1.6)℃ preopratively and(34.5±1.3)℃ postoperatively(P0.05).The skin temperatures of the left palm were(32.6±1.5)℃ preopratively and(35.0±1.3)℃ postoperatively(P0.05).The procedures were successful.There were no severe intro-and post-operative complications or mortality.One case presented the Horner syndrome.All cases were followed for 6~29 months,average 16.5 months,presenting an effective rate of 100%.Conclusion Sympathicotomy is a simplified method with little side effect and higher satisfactory rate.It should be recommended for the treatment of primary palmar hyperhidrosis.
Establish a method of cultivation and purification of dendritic cells (DCs) from mouse bone marrow in vitro to provide experimental material and establish basis for the study of immunological tolerance. BALB/c (H-2d) mice spleen lymphocytes and bone marrow cells were extracted under sterile conditions and cultured in RPMI 1640 medium. DCs were induced by recombinant granulocyte macrophage colony stimulating factor (GM-CSF) and interleukin (IL-4). Then, the morphology of DCs was observed under light microscopy and CD80, CD86 expression levels were detected by flow cytometry. The results showed that bone marrow cells appeared irregular and formed dendritic processes after 3 days cultured with stimulating factors in vitro which present the typical morphology of dendritic cells; Costimulatory molecules (CD80, CD86) were low expression on the cellular surface. Obtaining DCs from bone marrow cells is a promising method, which might meet further study on function, marker and anti-tumor role of DCs in vitro.

Objective Investigate the expression of Survivin in esophageal carcinoma and its relationship with clinical pathological parameter.Methods Examine the expression of Survivin in 35 cases of esophagus cancer,5 cases of normal esophagus tissue and 12 cases of adjacent tissue of esophageal carcinoma with imunohistochemistry.Results The 35 specimen in esophagus cancer tissue appeared Survivin positive expression,and only 1 specimen in normal esophagus tissue and adjacent tissue present Survivin weakly positive expression.The expression of Survivin had no relationship with histological type.There is significant difference between the average optical density of the cancer tissue and of the normal tissue(P0.05),while there is no significant difference between the average optical density of the lateral cancer tissue and of the normal tissue(P0.05).Conclusion The apoptosis inhibition caused by Survivin protein may play an essential role in the origin and progression of esophagus cancer.
Objective To explore the effect of Heller improved operation in the treatement of achalasia of the cardia.Method Total 50 patients with achalasia of the cardia,17 males,33 females,average age of 30.7 years(2~73 years).Heller improved operation and intravenous anesthesia with tracheal intubation were used.Results For 50 cases′ operations were success and none of them appeared esophageal rupture,the recovery rate was 99.60% and without pleural effusion.Conclusion Heller improved operation is a simplified method for achalasia of the cardia with fewer side effects and higher satisfactory rate.It is effective than conventional surgery.So this is a recommended surgical method of operation.
