The homeostasis of extracellular glutamate concentration is critically regulated by glutamate transporters(GTs).Malfunction or decreased expression of GTs has been implicated in the pathogenesis of various nervous system diseases.And among the GTs,glutamate transporter 1(GLT-1)plays a critical role as "glutamate pump".Recent research also finds some GLT-1 variants which alternate C-terminal splicings.Altered expression of proteins encoded by splice variants of GLT-1 has been noted in a number of disease states.Maintaining a physiological range of extracellular glutamate through regulating GTs expression or function may improve some pathological conditions.Many drugs are reported that can regulate GTs.For example,ceftriaxone,phencyclidine,citicoline,riluzole,AKT,thrombosin can up-regulate the expression or function of glutamate transporters;etomidate,clozapine,aspartic acid analogs,endothelin can down-regulate the expression or function of glutamate transporters.In this paper,the drugs which effect GTs will be summarized in order to provide a new insight into the drug design and clinical treatment of neurological diseases.

Objective To investigate the distribution and expression of adiponectin receptors in different tissues of normal Wistar rats. Methods The rats were euthanized and the total RNA was extracted from equal weight tissue samples of cardiac muscle, skeletal muscle, liver, kidney, testicle and fat. RT-PCR was employed to amplify the isolated cDNA, and the expression of adiponectin receptors in different tissues was semi-quantitatively analyzed. Results AdipoR1 was observed in rat cardiac muscle, skeletal muscle, liver, kidney, testicle and fat, with the highest expression in testicle and fat (P

Objective To investigate rats reared in social isolation as a model of behavioral symptoms of neurodevelop-mental psychiatric disorders including schizophrenia.Methods Male rat pups were housed in individual cages from post-weaning to adulthood.Locomotor activity detection, Morris water maze test and social interaction test were performed. Results Compared with controls, the social isolation-reared rats got more body mass, showed locomotor hyperactivity and increased social interaction, but significant spatial learning changes were not observed in Morris water maze test.Conclu-sion Exposing rats to social isolation can profoundly affect behavior in adulthood, which can be used to build animal mod-els of neurodevelopmental psychiatric disorders including schizophrenia.

Objective To explore the multiple risk factors for family lifestyle of children with congenital heart defects (CHDs) in Shaanxi Province, China. children and their parents. The univariate and multivariable logistic regression models were used to analyze the influence of risk factors related to parents' lifestyle on CHDs. Results Several possible risk factors were found for CHDs, including fever (OR=4.465, P=0.017), pesticides contact (OR=2.234, P=0.083), passive smoking during pregnancy (OR=20.529, P=0.007) and father's smoking (OR=3.342, P=0.005); fever (OR=2.428, P=0.012) and passive smoking during pregnancy (OR=1.201, P=0.037) were also correlated with ventricular sepal defect (VSD). Conclusion Fever, pesticides contact and passive smoking are associated with CHDs during pregnancy. We should focus our attention on health care during pregnancy to avoid the above-mentioned risk factors and call on parents to hold on to a good healthy lifestyle.

AIM The purpose is to study the anti-arrhythmic effects of extracts from cultured Cordyceps sinensis. METHODS Aconitine and barium chloride were used to induce experimental arrhythmia models in rats. RESULTS The results showed that PE was more potent than other ingredients. Pretreatment with PE by oral administration significantly antagonized arrhythmia induced by aconitine. PE significantly prolonged the onset of arrhythmia, decreased the duration and diminished the degree of severity. And in barium chloride-induced arrhythmia model, PE had some anti-arrhythmia effect,which could diminish the degree of severity effectively to some extent. CONCLUSION PE is an active component to antagonize arrhythmia induced by aconitine and barium chloride.

Nuclear factor erythroid-2 related factor 2 ( Nrf2 ) is an important nuclear transcription factor which protects cells a-gainst oxidative stress injury. Upon exposure to reactive oxygen species ( ROS) or electrophilic stress, Nrf2 can translocate into the nucleus, and then bind to the antioxidant response element ( ARE) , regulating the expression of several antioxidant enzymes and phase Ⅱ detoxifying enzymes which aimed at the detoxifica-tion and elimination of harmful exogenous chemicals, resulting in the facilitation of hepatoprotection. Oxidative stress is the com-mon pathogenesis of many liver diseases, while the Nrf2-ARE signaling pathway is extremely important in the prevention and progression of many liver diseases. Nrf2 has more recently been implicated as a new therapeutic target in treating liver diseases. Here, we focus on the most common liver diseases and the devel-opment of these conditions where activation of Nrf2 may alleviate disease progression, so as to provide reference for related re-search in the future.

Objective To compare two kinds of music therapy to improve the anxiety of ICU patients in order to explore the best setting of individual music therapy and improve efficiency of music therapy.Methods According to enrolling order,60 patients who had been in ICU for more than 1 week were divided into the test group and the control group with 30 cases in each group.The two groups both received conventional nursing.The test group listened to different music without time constrain every day.The control group received fixed music timing every day.Before and after intervention,the two groups were investigated with self-rating anxiety scale(SAS).Results The SAS score of the test group significantly decreased after intervention,showing statistical difference(P<0.01).The SAS score of the control group decreased after intervention as well,but showing no statistical difference(P>0.05).The score of the test group was lower than that of the test group after intervention,showing statistical difference(P<0.01).Conclusions The therapy using different music without time constrain has better effect on reducing the anxiety of ICU patients than that using timing and fixed music.

OBJECTIVETo explore the effect of Peitu Shengjin Recipe (PSR) on nutritional states and immune functions of stable phase chronic obstructive pulmonary disease (COPD) patients.
METHODSTotally 62 stable phase COPD patients were randomly assigned to the treatment group (30 cases) and the control group (32 cases). All patients inhaled Seretide (50/500 µg), twice per day. Besides, patients in the treatment group additionally received PSR, one dose per day. After three months of treatment, the COPD assessment test (CAT) score, the index of nutritional states [including body mass index (BMI) , thickness of skin fold (TSF), mid-arm muscle circumference (MAMC), serum albumin, serum prealbumin], and immune functions (including IgA, IgM, and IgG) were compared between the two groups.
RESULTSBy the end of the treatment, the CAT score decreased more obviously in the treatment group than in the control group (P < 0.05). The improvement of BMI, TSF, MAMC, serum albumin, and serum prealbumin was better in the treatment group than in the control group (P < 0.05). IgM and IgG also increased more in the treatment group (P < 0.05). There was no statistical difference in IgA between the two groups (P > 0.05).
CONCLUSIONSAdditionally use of PSR could improve nutritional states and immune functions of stable phase COPD patients to some extent. Meanwhile, it also could improve their health related quality of life.

Schizophrenia, described as the worst disease affecting mankind, is a severe and disabling mental disorder. Schizophrenia is characterized by complicated symptoms and still lacks a diagnostic neuropathology, so developing schizophrenia animal models which have quantifiable measures tested in a similar fashion in both humans and animals will play a key role in new therapeutic approaches. According to the symptoms of cognitive impairment and emotional disorder, the N-methyl-d-aspartate (NMDA)-receptor antagonist MK-801 was applied to induce schizophrenia-like behavior in mice. Locomotor activity and prepulse inhibition (PPI) were selected as indices and the effect of clozapine was also investigated in this model. The results showed that compared with the normal group, MK-801-treated mice exhibited significantly increased locomotor activity and impaired PPI, and pre-exposure to clozapine could ameliorate the abnormality and make it back to normal level. These findings suggest that the model we established could be a useful tool for antipsychotic drug screening.
