Neural system diseases are the significant burden threatening life quality of human beings. The investigation of stem cells especially the adult stem cells improved the related basic and clinical research of biological therapy and highlighted a prpspective future. The transplantation of adult stem cells maybe an effective method to treat neural system diseases. So the collaboration between the basic and clinical research will be strenthened to serve patients. Translational medicine is a potential field in which the basic medicine and clinical medicine and linked.

Diabetic peripheral neuropathy(DPN)is the most common complications of DM.It is considered to be progressive and irreversible.DPN occurred in a stocking and glove distribution,the mainly symptoms are pain,numbness and paresthesias.It is also the main cause of ulceration,infection and amputation.Usually,there is no special treatment for DPN besides blood-glucose control and pain control.Recently,Surgical decompression of peripheral nerves is used to restore sensation and relieve pian among DPN patients by Prof.Dellon and other doctors who have proved its efficacy in treatment of DPN.

The current therapeutic strategies for ischemic stroke are more limited. In the field of cell therapy, a series of basic and clinical research have suggested that bone marrow mesenchymal stem cells have therapeutic effect on ischemic stroke. This article mainly reviews the biological characteristics of bone marrow mesenchymal stem cells and the latest progresses in research on the treatment of ischemic stroke.

The neural stem cells (NSCs) can migrate into the injured area and differentiate into neurons or oligodendrocytes.Endogenous neurogenesis may potentially be harnessed as a putative therapy for neural injury.But the complex micro-environment due to TBI will be one of the biggest challenges for endogenous NSCs to perform neural regenerations.Exogenous NSCs have been shown to be able to survive in host tissues and regulate microenvironment via paracrine effects.Thus, transplantation of NSCs to assist neural regeneration has become an attractive option.Recently, rapid advances in the stem cell biology have raised appealing possibilities of replacing damaged or lost neural cells by transplantation of in vitro-expanded stem cells and/or their neuronal progeny.

Objective To investigate whether quantitative dynamic contrast enhanced MR can predict final pathologic response in primary breast cancer patients undergoing neoadjuvant chemotherapy (NAC).Methods Forty seven patients who were pathologically proved infiltrating ductal carcinoma with core needle puncture biopsy were examined before NAC and after 2 cycles of treatment and the quantitative parameters (Ktrans,Kep and Ve) were analyzed prospectively.Histological response is categorized as non-major histological response (NMHR) and major histological response (MHR).Quantitative parameter changes measured after 2 cycles of NAC were compared between MHR and NMHR using non parametric tests (Mann-Whitney U test) and pretreatment parameters were compared using independent samples t tests.Receiver operating characteristic curve (ROC) was used to determine the best predictor and cutoff value.Results Fifteen patients were grouped into MHR and 32 patients were NMHR.Pretreatment parameters(Ktrans,Kep and Ve) were(1.51 ±0.33) /min,(2.97 ± 1.06) /min and (0.55 ±0.16) in MHR and (1.53 ±0.40) /min,(2.82 ± 0.99) /min and (0.57 ± 0.20) in NMHR.There was no significant difference between the two groups (t values were-0.123,0.450 and-0.380,respectively,P ＞ 0.05).Changes inkinetic parameters(K,Kep and Ve) were-88.2％ (-96.0％ to 1.5％),-62.5％ (-94.3％ to -8.7％) and-57.0％(-82.1％ to 55.5％) in MHRand-8.1％(-88.5％ to 32.4％),-18.2％ (-62.1％ to 145.9％) and-4.7％ (-83.1％ to 95.7％) in NMHR.There were significant difference between the two groups (Z values were 4.359,4.359 and 3.332,respectively,P ＜ 0.01).The areas under ROC curve of AKtrans,AKep and Ktrans after 2 cycles of NAC were all 0.898.Sensitivity of the three parameters for predicting NMHR were 87.5％,90.6％ and 78.1％,and specificity were 86.7％,80.0％ and 93.3％,respectively.Conclusion Quantitative dynamic contrast enhanced MRI can predict final pathologic response in primary breast cancers after 2 cycles of NAC.

Objective:To explore the expressions of the nuclear factor-?B(NF-?B),C- myc and ICAM-1 in human colon and rectal cancer and the relationship between NF-?B and the occurrence,the metastasis of human colon and rectal cancer.The clinical significance was analyzed.Methods:Fifty human colon and rectal cancer cases ,16 colon and rectal adenomas,9 carcinomatous change of colon and rectal adenoma and 8 normal colon were studied,the expressions of NF-? Bp65,C- myc and ICAM-1 in them were examined by immunohistochemical method.Results:NF-?Bp65,C- myc were strongly expressed in the colon and rectal cancer and carcinomatous change of colon and rectal adenomas than those in colon and retal adenoma;C- myc could not express in normal colon;NF-? Bp65 and C- myc were significantly positive correlation with colon and rectal cancer;NF-?Bp65,ICAM-1 were strongly expressed in the colon and rectal cancer which had metastasis than those had no metastasis,and they had striking positive correlation with colon and rectal cancer which had metastasis.ConclusionTo control the transcription of C- myc and ICAM-1,NF-?B plays an important action in the occurrence and metastasis of colon and rectal cancer.It will become a new target of treatment of colon and rectal cancer.

Purpose:To investigate the expression of nuclear factor kappa binding (NF ?Bp65),c myc and intercellular adhesion molecule 1(ICAM 1) in colorectal cancer and its relation to clinicopathology.Methods:50 colorectal cancer patients who underwent radical surgery were studied, the expression of NF ?Bp65, c myc and ICAM 1 in them were examined by immunohistochemical method.Results:①In normal colon there was weak expression of NF ?Bp65, no expression of c myc and ICAM 1, NF kBp65,C myc and ICAM 1 were strongly expressed in colorectal cancer than in normal colon( P
