[Summary] The epithelial‐mesenchymal transition (EMT) is a biological process in which epithelial cells are converted into cells with mesenchymal phenotype in specified physiological and pathological conditions. EM T plays a critical role in proper embryonic development ,tissue regeneration ,cancer metastasis and organ fibrosis. EM T can be divided into three subtypes (Ⅰ ,II and Ⅲ ) based on different biological context ,of which type II EMT contribute importantly to the development of organ fibrosis.Renal interstitial fibrosis (RIF) is an important pathological feature of diabetic nephropathy (DN). The understanding of molecular mechanisms of this process tubular EM T may provide a clue to intervene the development of DN through suppressing EM T and reversing RIF.

objective To understand the clinical features of type 2 diabetes mellitus (T2DM) combined with metabolic syndrome (MS) in elderly patients, as well as the medicine used for treatment and the distribution of abnormal metabolic components. Methods Totally 349 T2DM patients admitted from 2001 to 2005 were retrospectively studied, among them 194 patients were combined with MS. The clinical data of those 194 patients were analyzed to evaluate their clinical feature, medicine used and the distribution of several abnormal metabolic components. of T2DM combined with MS. Results The proportion of MS in the elderly T2DM patients was 55.6%. Body mass index (BMI), postprandial blood glucose (PBG), blood pressure and triglyceride (TG) were higher than that in those patients of T2DM without MS, while the high density lipoprotein cholesterol (HDL-C) was lower (P

Objective To explore the clinical effects of diabetic nephropathy treated with enalapril and Yinxingdamo injection. Methods 80 patients were randomly recruited into a control group and a treatment group. The control group was treated with enalapril, and the treatment group was treated with Yinxingdamo injection on the basis of the control group. Results Comparing with the control group, the treatment group could be seen a obvious decrease of 24h UAE, BUN and Cr(P<0.01). Conclusion The therapeutic effects of combined using enalapril and Yinxingdamo injection is better than only using enalapril in treating diabetic nephropathy.

Objective To investigate the biological characteristics of neural stem cells from the striatum of human embryos. Methods Neural stem cells were isolated from the striatum of 16-20 weeks human embryos.These cells were cultured to proliferate and then differentiate without mitogens or inductive factors.At various time points the progeny of neural stem cells differentiation were analyzed.Using immunocytochemistry stainings,the biological characteristics of neural stem cells were examined. Results Neural stem cells in the striatum of 16-20 weeks human embryos proliferated rapidly in vitro within the first one month of culture at an average doubling time of 3-4 days.Upon mitogen withdrawal,the differentiation of neural stem cells to neurons exceeded 50%.After 8 weeks in culture,however,the proliferation speed of neural stem cells lowered significantly.The proportion of neurons induced by mitogen removal was under 20%.There were about 20% of cells within neurosphere continue to divide.Conclusion The proliferation and self-renewal ability of neural stem cells in the striatum of 16-20 weeks human embryo is robust.In vitro,the rate of proliferation went down with time,and the ability of differentiation to multiple neural cells varied.The different mitogen factors in media have different effects on neural stem cell.Within neurospheres,neural stem cells are not homogenous,as only a portion of cells can divide.

Objective: To study caspase-3 activities and the neuroprotective effect of caspase-3 inhibitor Ac-DEVD-CMK in primary cultures of rat hippocampal neurons during hypoxia/reoxygenation (H/R). Methods: After pretreated with Ac-DEVD-CMK or the vector DMSO fo 1 h, primary cultures of rat hippocampal neurons were induced to hypoxia for 3 h, followed by 12 to 48 h of reoxygenation. The neuronal viability was estimated by MTT assay, and caspase-3 cellular activities were measured by a colorimetric method using Ac-DEVD-pNA as a substrate. Results: During H/R, the cultured rat hippocampal neuronal viability gradually decreased, and caspase-3 activities in the primary cultures of rat hippocampal neurons were significantly increased, and peaked at 24 h of reoxygenation. Caspase-3 activities were decreased in the neurons pretreated with Ac-DEVD-CMK in a dose dependent manner. Conclusion: Delayed neuronal death is detected in cultured hippocampal neurons during H/R, and apoptosis mediated by caspase-3 may play an important role in it, and caspase-3 inhibitor has a neuroprotective effect on them.

Objective To investigate the changes of cellular immunity and humoral immunity in children with acute or critical illness. Methods Seventy-three critically ill children admitted to PICU of Chil-dren′s Hospital Affiliated to Fudan University during the period from April,2015 to September,2015 were the objects of study. Blood samples were collected within 48 hours after admition. The lymphocyte subpopulation was measured by flow cytometry,and the level of humoral immunity was measured by rate immune scatter turbidimetry,and the neutrophil function was measured by flow cytometry-DHR analysis. Twenty-three cases from 73 cases were detected the second time after admitted to hospital for seven days. Ten health children be-fore elective surgery were selected as control. Results (1) Compared with the control,the percentages of CD3 +T cells and CD8 +T cells were significantly decreased in critically ill children within 48 hours of admis-tion[(57. 43 ± 13. 46)%,(21. 26 ± 7. 87)% vs. (66. 24 ± 5. 27)%,(26. 82 ± 7. 63)%,P<0. 05]; At the same time,CD4 +T cells and NK cells had no significant change[(33. 42 ± 11. 29)%,(8. 83 ± 7. 77)% vs. (34. 89 ± 4. 94)% (11. 34 ± 5. 60)%,both P<0. 05]; While B cells were significantly increased[(31. 69 ±13. 83)% vs. (21. 08 ±7. 24)%,P<0. 05]. Neutrophil activation rate[(14. 32 ±14. 81)%] was signifi-cantly higher than the normal reference value ( 0 -10%) and the activation rate was more than 90% after stimulated by PMA. The plasma level of complement C3[(0. 88 ± 0. 31) g/L] was lower than that of the control group[(1. 19 ± 0. 18)g/L,P<0. 05]. (2) Compared with the first time,the percentages of CD3 +cells and CD4 + cells were increased after treated for one week in 23 patients[(61. 20 ± 13. 56)%,(36. 79 ± 9. 95)% vs. (56. 80 ± 13. 99)%,(32. 86 ± 10. 87)%,both P<0. 05]. No significant difference in neutrophil activation and activation rate after PMA stimulation was found compared with admition. IgA,IgM and comple-ment C3 were significantly increased[(0. 98 ± 0. 75) g/L,(1. 00 ± 0. 39) g/L,(1. 15 ± 0. 34) g/L vs. (0. 80 ± 0. 69) g/L,(0. 86 ± 0. 48) g/L,(0. 93 ± 0. 23) g/L,all P<0. 05]. Conclusion Immune disorders occur in critically ill children in the early stage of illness,the most obvious change is cellular immune response,and im-mune function starts to recover after one week.
