Diabetic neuropathy is the most common peripheral neuropathy,and it is important to enhance both nerve regeneration and prevent nerve degeneration in its treatment. Disturbed nerve regeneration in diabetes has been ascribed,at least in part,to decreases of some neurotrophic factors or the decreases of their receptor expressions.This paper reviewed the effect of some major neurotrophic factors on diabetic neuropathy and their application in clinical treatment.

Combining with traditional medical ethics for medical students to carry out the cultivation of core so -cialist values is a specific and realistic path .Virtue ethics features of traditional medical ethics are good for medical students to internalize core socialist values .Normative characteristics of traditional medical ethics are good for med-ical students to be cultivated of social responsibility , sense of responsibility to life , dedication and integrity aware-ness .By demonstrating the role of ethics and ancient doctors′model in classic literature , students can not only un-derstand the rich connotations of traditional ethics of traditional culture , but also get the cultivation and practice of core socialist values .

Objective　To observe about curative effect of MMF on type Ⅳ lupus nephritis and to review the literature about MMF used to treat LN.Method　Ten patients with type Ⅳ LN were treated with MMF 1～2 g/d plus prednisone at middle or little dose.Curative duration of these patients was between 6 and 12 months.After 3,6 and 12 months curative effect was observed.Results　After treatment proteinurie and systemic lupus activity measurement were decreased gradually.Before and after treatment ANA positive rates were 80% and 30%,anti dsDNA antibody positive rates were 50% and 10%,respectively,and low C3 and C4 was rectified.After treatment renal failure in 3 patients was recovered.During treatment major adverse reactions included gastrointestinal symptoms and herpes zoster.Conclusion　MMF has exacttly effect on type Ⅳ LN and low side effect.

Objective:To investigate the effect of mycophenolate mofetil(MMF)on proliferation and apoptosis of cyst-lining epithelial cells in patients with autosomal dominant polycystic kidney disease(ADPKD),and to compare its effect with that of rapamycin(RAPA)in vitro.Methods: Primary cultured cyst-lining epithelial cells were treated with MMF and RAPA at different concentrations(0,0.005,0.05,0.5,5 ?g/ml)for 48 h or 72 h.The inhibitory effects of them on the cells were evaluated by MTT assay;the cell cycle distribution and apoptotic ratio were determined by flow cytometry.The morphological changes of cyst-lining epithelial cells were observed under transmission electron microscope.Results: Both MMF and RAPA significantly inhibited the proliferation of cyst-lining epithelial cells in a dose-and time-dependent manner.After 48 h treatment,the cells were blocked at S phase by MMF and at G0/G1 phase by RAPA.Both drugs induced cell apoptosis,with the maximal apoptotic rate being(5.53?0.27)% for MMF and(4.36?0.10)% for PAPA.Typical morphological changes of apoptotic cells were observed under electron microscope.Conclusion: MMF can effectively inhibit proliferation and induce apoptosis of cyst-lining epithelial cells,but its inhibitory effect is weaker than that of RAPA.

Objective To investigate the psychology and personality factors which affect soldiers' psychological health, in order to provide theoretical evidences for the changes in psychology among recruits engaged in tunnelling operation. Methods Using psychological health questionnaire (SCL-90) and Eysenck personality questionnaire (EPQ), 1191 recruits of missile army recruits were tested before and after the mission of tunnelling in 2004~2005 (with the exclusion the dropped outs, those who were transferred or did not complete the whole test period). Results After entering the tunnel, scores of human relationship sensitivity, anxiety, fright and positive items of the recruits were all higher than before the mission or that of servicemen′s norms. In a group of 931 healthy recruits, 157 turned sub-healthy, while 35 of a group of 260 sub-healthy turned healthy. Using EPQ to investigate the personality of these 2 groups, the C value of the former group was found to be on the high side, and this result showed that there had a tendency of concealment and pretension before entering the tunnel. The turnover observed in the latter group maybe due to their extroversion personality. The SCL-90 test of the latter group showed that it was also related to a lowering of score of human relationship sensitivity. Conclusion It shounld be emphasized that it is important to conduct self-education and psychological mediation for the recruits to improve relationship sensitivity and to allay anxiety and fear for the reeruits before and after the tunnelling operation, in order to improve their psychological health status.

Objective To observe the effects of exercises on early stage of steroid-induced necrosis of the femoral head in rabbits with magnetic resonance imaging (MRI). Methods 24 adult rabbits were divided randomly into three groups, i.e. control group (group A), routine model group (group B) and experimental group (group C) with 8 animals for each group. Dexamethasone (DXM) was administrated in a dosage of 2.5mg/kg via intramuscular route to reproduce the aseptic necrosis of femoral head (ANFH) model in groups B and C, while only isotonic physiological saline was given to the animals in group A. MRI examinations were done at 2nd, 4th, 6th and 8th week after administration of DXM for bilateral femoral heads, and also on a medial coronary area of the hip joints with a fixed area of circumambient soft tissure of 3 mm in diameter. Results At 2nd, 4th, 6th and 8th week after the reproduction of the model, the t2-de3d-sag spot-signals given by MRI in the circumambient soft tissue of hip joints were 56.26?0.45, 58.05?0.27, 59.04?0.29 and 59.23?0.25 in group A, 61.40?0.41, 63.71?0.34, 69.65?0.28 and 71.84?0.3 in group B, and 59.54?0.39, 60.06?0.32, 62.71?0.19 and 63.18?0.40 in group C, respectively. Significant differences existed between each of two groups (F=84.93, P

Objective To study the quantitative method of determination of Fas ligand (FasL) and T-cell intracellular antigen-1 (TIA-1) in renal allografts and to evaluate its clinical significance. Methods The magnitude of intragraft FasL and TIA-1 mRNA was quantified by competitive PCR in 42 samples obtained to diagnose the etiology of graft dysfunction, and the results were expressed as the ratio of picograms of target gene to picograms of ?-actin, and were compared with the histopathogical diagnosis based on Banff criteria. Results Of all 42 samples, the transcripts were detectable in 11 for FasL and 27 for TIA-1. Intragraft expression of FasL and TIA-1 was significantly up-regulated in acute rejection group compared with chronic rejection group (P

Objective To reproduce an animal model of psychological simulation training,and to investigate the influence of psychological training on the ability of counter physical stress.Methods Thirty-two Wister rats were assigned to four groups,8 for each,namely control group(group A),psychological training group(group B),stress group(group C)and psychological training prior to stress(group D).Rats in group A received neither psychological training nor stress,group B received psychological training without stress,group C received stimulation including stress of strong noise and strong light,but without psychological training,and group D,after psychologically training for 4 weeks,received the same stress stimulation as group C.Twenty-four hours after stress,open-field experiment was done on group C and D.At last,rats in all the 4 groups were anesthetized by ether and 5ml of blood was drawn from each rat in order to detect the content of beta-endorphin(?-EP),corticosterone and IL-1?.Results In the open-field experiments,the psychologically trained groups(B and D)showed remarkably lower scores than the un-trained groups(A and C).The levels of ?-EP and corticosterone were significantly elevated in rats after receiving stress stimulation,while that of IL-1? lowered dramatically.The level of ?-EP and corticosterone in psychological training group(group D)was remarkably lower,while that of IL-1? was higher,than the stress group(group C)during the stress.Conclusion Psychological training can lessen the inhibitory effects of harmful stress on endocrine and immunologic functions,and enhance the physical ability to confront stress.

Objective To define the relationship between genes expression of 5 immune effector molecules and acute rejection of renal allografts. Methods The magnitude of intragraft Fas, Fas ligand (FasL), granzyme B(GB) , perforin(P) and T cell intracellular antigen-1 (TIA-1) mRNA were quantified by competitive PCR in 42 samples. Results were expressed as the ratio of picograms of target gene to picograms of ?-actin, and were compared with the histological diagnosis based upon Banff criteria. Results Of all 42 tissues, the transcripts were detectable in 41 for Fas, 11 for FasL, 19 for GB, 33 for P and 27 for TIA-1. Intragraft expression of FasL, GB, P and TIA-1 but not Fas was significantly elevated in acute rejection group as compared with chronic rejection group ( P
