Parkinson's disease(PD)is a neurodegenerative disease that predominantly affects the elderly.Dopamine mimicking drug is the mainstay in the treatment of Parkinson's disease.However,there is a large of interindividual variability in response to anti-Parkinson's disease drugs.It is thought that genetic variability in dopamine system genes is one of the important factors in determining interindividual variability in drug response.There are a lot of studies focused on the relationship between the risk of Parkinson's disease and genetic variations in domestic,while it is a lack of the pharmacogenetics study on Parkinson's disease.This review summarizes the relationship between the polymorphism of genes encoding dopamine transporter,dopamine-metabolizing enzymes and dopamine receptors and Parkinson's disease treatment.

Diabetic nephropathy is one of the most serious complications of diabetes mellitus and it seriously endangers people's health.Some previous studies indicate that the occurrence and development of diabetic nephropathy is not positively associated with control of blood glucose and course of disease,Its development has family aggregation and ethnic differences.In addition to environmental factors,genetic factors play an important role in the process of occurrence and development of diabetic nephropathy,Many genetic mutations can lead to a high degree of susceptibility to diabetic nephropathy.Discovery of some related genes of diabetic nephropathy and elucidation of these genes function provide an effective means in the early diagnosis,gene therapy and individualized drug therapy of diabetic nephropathy.In this review the action and function of discovered related genes of diabetic nephropathy are summarized.

Objective To explore the clinical features of hyperthyroidism combined with Moyamoya disease. Methods The manifestations of clinic and neuroimaging in 4 patients with hyperthyroidism combined with Moyamoya disease were retrospectively analyzed.Results 4 patients were young or middle-aged females and onset of the disease were acute or subacute. 2 cases had the history of hyperthyroidism for 4 and 1 years and other 2 cases were diagnosed of hyperthyroidism in the duration of hospital stay. All of them presented with focal neurologic deficit(3 of motor weakness or fatigue in the limbs, 2 of facial paralysis and 2 of aphasia). All of them had thyromegaly Ⅰ?～Ⅱ? and 1 of them had vascular murmur in thyroid region.Thyroid function tests revealed thyrotoxicosis, the level of fT3 was 10.1～30.8 pmol/L,the level of fT4 was 17.9～154.8 pmol/L, the level of TSH was 0.01～0.1 mU/L.DSA or MRA showed stenosis or occlusion of the terminal portions of the bilateral or unilateral internal carotid arteries and abnormal vascular network in the vicinity of the arterial occlusion. The patients recovered after the anti-thyroid therapy and treatments for the cerebral stroke. Then ,15 ～ 60 months were followed up respectively, there was no relapsed of cerebral stroke in them. Conclusion Hyperthyroidism combined with Moyamoya disease is only seen in females. Cerebral stroke is occurred during the presence of thyrotoxicosis. Anti-thyroid treatment is beneficial for recovery of the centre nervous system and prevention of recurrence.

Fluoxetine is a relatively novel class of selective serotonin reuptake inhibitors (SSRIs) with antidepressant properties. It seems to facilitate serotonergic transmission via down regulation of presynaptic inhibitory autoreceptors, with no effect on muscarinic receptors and doubtful effects on ? adrenergic receptors. Fluoxetine is mainly metabolized by cytochrome P450 (CYP) isoenzymes. It has been shown that CYP2C9、CYPD6, and CYP2C19 are major CYP isoforms responsible for the N demethylation of fluoxetine. Since both fluoxetine and its main metabolite norfluoxetine are the inhibitors of CYP2D6, CYP3A4, CYP2C9, and CYP2C19, there are some drug drug interactions of fluoxetine with other drugs for metabolism by those CYP isoenzymes, which results in interindividual differences in the pharmacokinetics and efficacy.

The human ?3-adrenoceptor plays an important role in the regulation of energy mobilization and utilization. A missense mutation in codon 64 of the gene for the ?3-adrenoceptor with a replacement of tryptophan to arginine (Trp64Arg) was found. This polymorphism influences receptor function when expressed in artificial cell lines or in isolated human fat cells. It is associated with an earlier onset of type 2 diabetes mellitus, features of insulin resistance and tendency to gain weight. Recent evidences suggest that Trp64Arg has additive and interactive effects with a number of other candidate gene variants. The functional significance of human ?3-adrenoceptor polymorphism and its association with metabolic diseases are reviewed in this paper.

The roots of Glycyrrhiza uralensis are widely used in Chinese medicine for their action of clearing heat, detoxicating, relieving cough, dispelling sputum and tonifying spleen and stomach. The reason why Glycyrrhiza uralensis has potent and significant actions is that it contains various active secondary metabolites, especially glycyrrhizic acid. In the present study, we cloned the cDNA coding 3-hydroxy-3-methylglutary CoA reductase (HMGR) involved in glycyrrhizic acid biosynthesis in Glycyrrhiza uralensis. The corresponding cDNA was expressed in Escherichia coli as fusion proteins. Recombinant HMGR exhibited catalysis activity in reduction of HMG-CoA to mevalonic acid (MVA) just as HMGR isolated from other species. Because HMGR gene is very important in the biosynthesis of glycyrrhizic acid in Glycyrrhiza uralensis, this work is significant for further studies concerned with strengthening the efficacy of Glycyrrhiza uralensis by means of increasing glycyrrhizic acid content and exploring the biosynthesis of glycyrrhizic acid in vitro.

Aim ?3 adrenoceptor(?3-AR) is predominantly expressed in white and brown adipose tissue.?3 adrenoceptor agonist stimulates the lipolysis of white adipose tissue and non-shivering thermogenesis of brown adipose tissue to exert its antiobese action.Moreover,?3 adrenoceptor agonist increases the sensitivity and response of adipose tissue to insulin and it play an important role in the treatment of type 2 diabetes.In addition,?3 adrenoceptor agonist can also relax gastrointestinal spasm and show cardiovascular effect in human heart and vascular tissues.There has been increasing concerned in the study and development of ?3 AR agonists since 1983.Up to date,32 kinds of ?3 AR agonists have been identified.The development of ?3 AR agonists can provide new strategy and approach for pharmacotherapy of obesity and diabetic mellitus and will have Spaciously the used out look in the field of medicine.

The prevalent rates of overweight and obesity are steadily increasing all over the world. Previous studies of some candidate genes have indicated that most of the genes are associated with obesity in human adipose tissue. As much as 40% of the variations in body mass could be attributed to genetic difference. The β-adrenergic receptor (β-AR) plays a major role in the regulation of energy balance in humans. A high sympathetic nervous system activity has been shown to be associated with obesity and is believed to have pathogenetic relevance. Several common single nucleotide polymorphisms (SNPs) including Gly389Arg in β1-AR, Gln27Glu in β2-AR, and Trp64Arg in β3-AR in humans could alter receptor function and these variations ofβ-ARs were shown to have certain association with obesity. Here we summarize the genetic polymorphisms of human β-ARs and their potential impacts to obesity.
