The nuclear factor erythroid 2 related factor 2 (Nrf2) is a key protein of endogenous antioxidant defense systems in the body. In response to oxidative stress, Nrf2 translocates to nucleus and binds to antioxidant response elements (ARE), regulating the expression of a large amounts of antioxidant genes and maintaining a proper redox balance. The pathological processes of neurodegenerative diseases are associated with generation of reactive oxygen species, which cause oxidative stress. Oxidative stress plays a cardinal role in the onset and progression of neurodegenerative diseases. Nrf2-inducer compounds can reduce oxidant stress and have shown therapeutic efficacy in many neurodegenerative disease models. How to activate the Nrf2 signaling pathway effectively has been received much attention. Here we provided an overview of specific mechanism of Nrf2-ARE pathway and the protective effects of Nrf2 in different neurodegenerative diseases, and summarized the Nrf2 activators recently in preclinical study.

Objective: To investigate the effect of scutellarin after cerebral ischemia-reperfusion injury in rats with hyperlipemia, by observing the expression of B-cell lymphoma-2 (Bcl-2) and Bcl-2 assaciated X protein (Bax) in cerebral cortex with hyperlipemia. Methods: After the rat model of hyperlipidemia was established, the focal cerebral ischemiareperfusion model in hyperlipemia rats was established with thread embolism of the middle cerebral artery. The neurobehavioral score was used to observe the symptoms of neurobehavioral injury. 2,3,5 -triphenyl tetrazolium chloride (TTC) staining was used to observe the cerebral infarct volume. HE staining was used to observe the pathological changes of brain tissue. Immunohistochemistry and Western blotting were used to observe the expressions of Bcl-2 and Bax. Results: Compared with the sham-operation group, the neurobehavioral scores,cerebral infarction volum and pathologic damage were significantly increased, the expressions of Bcl-2 was significantly lower, the expressions of Bax was significantly increased in ischemia-reperfusion group(P<0. 05). Compared with the saline group, the neurobehavioral scores, cerebral infarction volum and pathologic damage were significantly decreased, the expression of Bcl-2 was significantly increased, the expression of Bax was significantly decreased in scutellarin treatment group (P<0. 05). Conclusion: In cerebral ischemiareperfusion injury rats with hyperlipemia, scutellarin can alleviate cerebral ischemia-reperfusion injury by promoting the expression of Bcl-2 and inhibiting the expression of Bax.

Objective To explore the changes of plasma brain natriuretic peptide(BNP) and N-terminal pro-B-type natriuretic peptide (NT-proBNP)of sepsis combined with myocardial injury in newborns.Methods According to neonatal sepsis treatment program,45 cases of sepsis newborns in NICU of the Second Hospital in Lanzhou University from Jul.2007 to Jun.2008 were collected.According to the myocardial injury diagnostic criteria,45 cases neonatal sepsis were divided into myocardial injury group(n=22) and non-myocardial injury group(n=23).Myocardial injury group was also divided into congenital heart disease group and non-congenital heart disease group accor-ding to echocardiography.At the same time,30 healthy newborns were collected as healthy control group.Every newborns were tested the level of plasma BNP,NT-proBNP,creatine kinase-MB(CK-MB) and cardiac-troponin I (cTnI).Results There were significant difference between myocardial injury group,non-myocardial injury group and healthy control group in the levels of plasma BNP,NT-proBNP,CK-MB and cTnI,those in congenital heart disease group were higher than those in non-myocardial injury group and the healthy control group(Pa0.05).Conclusions BNP and NT-proBNP can be early used to diagnose myocardial injury and heart failure of neonatal sepsis associated with CK-MB and cTnI.In NICU,infants with sepsis should normally test BNP and NT-proBNP in order to early diagnose myocardial injury of neonatal sepsis.

Objective To observe the therapeutic effect of single lower limb traction plus massage for the lumbosacral tunnel syndrome.Methods The selected 80 candidate patients were divided into the observation group with 38 patients and treatment group with 39 patients. The observation group received single lower limb traction plus massage and the treatment group received pelvic traction plus massage. Both groups therapy last 5 days, The Japanese orthopaedic association scores (JOA) was evaluated for subjective symptoms, signs, functional activity and bladder function score. The therapeutic effect was evaluated.Results The total effective rate (94.7% vs. 82.1%;χ2=12.160,P=0.007) in the observation group was significantly higher than that in the control group. O, The scores of JOA at one week after treatment (20.2 ± 2.0 vs. 18.3 ± 2.8;t=3.419, P<0.01) and two weeks after treatment (24.4 ± 1. 4vs. 22.6 ± 3.0;t=3.359,P<0.01) in the observation group were significantly higher than those in the control group.Conclusions The single lower limb traction plus massage can improve the clinical symptoms of patients with lumbosacral tunnel syndrome, and be superior to the pelvic traction plus massage.

ObjectiveTo explore the relative factors of the compliance in schizophrenic out-patients.Methods118 schizophrenic out-patients chosen randomly were investigate with the compliance and assessed with Clinical Global Impression-Severity of Illness (CGI-SI), Social Disability Screening Schedule (SDSS), Brief Psychiatric Rating Scale (BPRS) and Treatment Emergent Symptom Scale (TESS) by telephone. Logistic regression analysis was used to confirm the relative factors of the compliance.Results56.8% of all patients were of full compliance. The risk factors of compliance in schizophrenic out-patients were the frequency of medicine taken, the scores of CGI-SI and the insight of the illness. ConclusionIt is important to choose effective and convenient antipsychotic drugs and improve the insight of the illness to enhance the compliance of the schizophrenic out-patients.

Mitochondrial dysfunction has been implicated in the aetiology of sporadic Parkinson's disease but its role in the disease mechanism remains unclear.To investigate the effect of synuclein on mitochondrial dysfunction induced by rotenone.The human dopaminergic SH-SY5Y cells were used as a cell model.The cells over-expressed the wild-type ?-synuclein were treated with complex I inhibitor rotenone.The cell viability,complex I activity,Mitochondrial swelling and O2-content were tested at different time point-1w,2w,4w after rotenone treated.CCK-8 test results showed that the cell viability of overexpressed ?-synuclein(SH-SY5Y-Syn)was much lower than the control group(SH-SY5Y-Ctr).After administrating with rotenone about 1w or 2w the cell viability of SH-SY5Y-Syn became higher than that of SH-SY5Y-Ctr.On the 4th week the results were contrary to the first 2 weeks.Similar results were got when test the mitochondrial function.In the first 2 weeks after roteoone administrating,the mitochondrial function of SH-SY5Y-Syn was better than that of SH-SY5Y-Ctr.This suggest that the ?-synuclein could protect the mitochondrial against the injury induced by rotenone in the early stage-1w,2w,while this effect disappeared in the final stage-4w.

Objective To explore the causes of subclinical hypothyrodism in children and the effects of the interventional therapy with thyroixine on the course of it.Methods Two hundreds children with subclinical hypothyroidism were measured for thyroglobulin antibody(TGAb),thyroid microsomal antibody(TMAb) in the blood serum,examined by colord Dopplor ultrasonic,examined by fine needle aspiraton cytology of the throid and measured the rate of 131I absorbed by thyroid in order to find out the causes of the disease.Two hundreds cases were randomly divided into two groups on the base of the cause of diseases,treatment group 100 cases and control group 100 cases.The treatment group were treated by throxine 25-75 ?g/d and the therapeutic dosage were chosen with the normal value of free triiodothyronine(FT3),free thyroxine(FT4)and high sensitive thyrotropin(sTSH) in the blood serum .After one year thyroxine therapy were stopped.Thyroid function was examined 6 months later after stopping the thyroxine.Results Among all of the causes of subclinical hypothyroidism in children,Hasgumoto′s thyroiditis accounts for 56%,simple goiter accounts for 26%,antithyroid drug accounts for 6%,the lack of thyroxine substitution therapy on the hypothyroidism accounts for 5% and undefined causes accounts for 7% .The thyroid function could keep normal for 1 year with an alternative therapy with thyroxine on subclinical hypothyroidism in children.Half a year later after stopping thyroxine,the thyroid function turned normal in most of the children.There were obvious differences in the ratio of cure and the ratio of effectiveness between treatment group and control group (t=20.2,3.2 Pa
