BACKGROUND:Mesenchymal stem cells are found to have the immunoregulatory activities and a potential application prospect in the treatment of autoimmune diseases.
OBJECTIVE:To explore the mechanism of transplanting mesenchymal stems cells on the treatment of multiple sclerosis.
METHODS:The mouse mesenchymal stems cells were prepared, and injected into the al ogenic and syngenic normal mice, to detect the frequency of CD4+CD25+Foxp3+T cells in the spleen, thymus, and lymph nodes by flow cytometry, and to detect the Foxp3, transforming growth factor-β1, and interleukin-10 mRNA in the spleen, thymus, and lymph nodes by reverse transcription-PCR.
RESULTS AND CONCLUSION:Transplantation of mesenchymal stem cells on normal mice led to a significant up-regulation of CD4+CD25+Foxp3+T cells, Foxp3, transforming growth factor-β1, and interleukin-10 mRNA in the spleen, thymus, and lymph nodes both in the al ogenic and syngenic transplant groups. Transplantation of mesenchymal stem cells may be an available method in the treatment of autoimmune diseases, and CD4+CD25+Foxp3+T cell, Foxp3, transforming growth factor-β1, and interleukin-10 may be involved in this process.

Objective To investigate the effect of Rumo Shengji San on promoting tissue regeneration of skin defect after repair with tissue-engineered skin.Methods The dermal scaffolds were reconstructed by collagen sponge in which human skin fibroblasts were transplanted inside and human keratocytes were transplanted on the surface.The tissue-engineered skin was transplanted into the wound surface of defected skin in naked mice.Rumo Shengji San was applied externally once every other day after transplantation for 2 days.The animals were randomly divided into two groups:external application group and control group,4 mice in each group.The differentiation tissue of the tissue-engineered skin was sampled 9 days after transplantation.The epidermis thickness and dermal capillary proliferation in wound of defected skin were observed with HE staining,and double-labeled immunofluorescence method was used to test dermal laminin(Ln) and typeⅠcollagen protein expression.Results Rumo Sheng Jji San promoted the development of epidermis after transplantation for 9 days.The number of capillaries in dermis was increased,and the expression of Ln and typeⅠcollagen protein was promoted in external application group than that in the control group.Conclusion Rumo Shengji San can promote tissue regeneration of skin defect after repair with tissue-engineered skin.

Objective:To investigate perioperative management of anesthesia for septic shock.Methods:Anesthesia performed on an elderly patient with septic shock who underwent emergency surgery in Beijing Hospital was analyzed and summarized, with a literature review.Results:Etomidate, Ketamine, cis Atracurium and Remifentanil are preferred for anesthesia induction, and Remifentanil and Sevoflurane are the first choices for anesthesia maintenance.Combined application with Dexmedetomidine may improve patients' prognosis.For septic shock patients with new-onset atrial fibrillation, β-blockers are preferred for perioperative anti-arrhythmia.If necessary, propafenone or amiodarone can be used for cardioversion.Perioperative ultrasound evaluation may be used to guide perioperative fluid therapy and vasoactive drug administration for septic shock in the future.Conclusions:Anesthesiologists should place a high value on and have a good command of the main aspects of perioperative management of anesthesia for septic shock.

Objective To observe the effects of electro-acupuncture (EA) on body weight, insulin resistance, hypothalamic agouti gene-related protein (AGRP) and neuropeptide Y (NPY) in diet induced obesity (DIO) rats; To discuss its mechanism for DIO.Methods Fifty SD male rats were randomly divided into low fat diet groups (LFD) and high fat diet group. After the DIO models were established, the successful model rats were randomly divided into model group, EA group and Orlistat (OLST) group. EA was applied to “Zusanli” (ST36) and “Quchi” (LI11) for 20 minutes. The treatment was done once a day for 28 days. OLST was treated with orlistat by gavage. LFD and model did not receive treatment. Body weight was recorded every day. FPG and FINS were detected. The expressions of AGRP and NPY were detected by RT-QPCR. Morphological changes of adipocyte and liver were examined by HE staining.Results The body weight, HOMA-IR, AGRP, NPY and diameter of adipocyte of EA group and OLST group were significantly lower than model group (P<0.05), difference between EA group and OLST group. The states of hepatic steatosis were improved in EA group and OLST group.Conclusion EA has the effects on weight loss by inhibiting the expressions of AGRP and NPY by improving IR.

Objective To examine the mechanism by which miR-155-5p regulates sex determining region Y-boc 1(SOX1) expression in breast cancer cell line MCF-7,and to investigate the effect of miR-155-5p on the invasion and metastasis of these cells.Methods After up-regulation or down-regulation of the expression of miR-155-5p in MCF-7 cells,the transwell assay was performed to detect the invasive and migrating ability of MCF-7 cells;SOX1 mRNA expression and protein levels were detected by real-time PCR and Western blot,respectively;immunofluorescence was used to test the distribution and levels of SOX1 pro-tein,and dual luciferase reporter experiments to discover the binding of miR-155-5p to the 3′-UTR region of SOX1 mR-NA.Results Up-regulating the expression of miR-155-5p could enhance the migrating and invasive ability of MCF-7 cells and simultaneously decrease the mRNA and protein levels of SOX1(P <0.05).On the contrary,inhibition of miR-155-5p depressed the invasion and migration of MCF-7 cells and increased the expression of SOX1(P < 0.05).Dual luciferase reporter experi-ments confirmed that miR-155-5p could bind to the specific sequence in the 3′-UTR of SOX1 mRNA and play a role of regula-tor.Conclusion miR-155-5p promotes the invasion and migration of breast cancer cell line MCF-7 via inhibiting the expression of SOX1.
