Objective To investigate the association of polymorphisms in dopamine D3 receptor (DRD3) gene exon 1 Ser9Gly with childhood tourette syndrome and efficacy of aripiprazole in Chinese Han population.Methods Polymorphisms of Ser9Gly in DRD3 gene was genotyped by using Polymerase Chain Reaction-Restriction Fragment Length Polymorphism (PCR-RFLP) in 158 tourette syndrome patients (study group) and 187 healthy controls (control group).Patients in study group were assessed with Yale global tic severity scale(YGTSS) at baseline and at the end of the 8th week of treatment to evaluate the efficacy of aripiprazole.Results (1) There were no significant differences in genotypic frequency and allelic frequency of Ser9Gly in DRD3 gene between study group and control group (P＞0.05).(2) Significant difference was found in frequency of Ser9Gly in DRD3 gene between effective and ineffective groups (genotype:Ser/Ser 40 vs 17;Ser/Gly 52 vs 28;Gly/Gly 7 vs 14;alle:Ser 132 vs 62;Gly 66 vs 56)(P＜0.05).(3) There were no significant differences in distribution of genotypes and alleles of Ser9Gly among three-type of tourette syndrome (P＞0.05).Conclusion The polymorphisms of Ser9Gly in DRD3 gene are associated with the efficacy of aripiprazole.

Dysfuntion ofα cells plays a critical role in the pathogenesis of diabetes. Its own transcription factors, posttranscriptional modification, transporters related to secretion and paracrine signals fromβ and δ cells, inflammatory factors, and carbohydrates, lipids, amino acids, all influenceαcell function. We summaried the various factors involved in the regulation ofαcell function as well as recent related advances on their molecular mechanisms.

Objective: To study the clinical features of dengue cases infected with hepatotropic virus and Mycobacterium tuberculosis in Xishuangbanna, and to provide evidences to set up effective treatment programs for the dengue patients infected with the other diseases for hospitals. Methods: The clinical characteristics of dengue cases infected hepatotropic virus and Mycobacterium tuberculosis were analyzed retrospectively on their symptoms and biochemical parameters from the People′s Hospital and the Infectious Disease Hospital of Xishuangbanna Prefecture in 2013 and 2015. Results: The clinical characteristics of dengue cases infected with hepatotropic virus were typical, and inclued low incidence of urinary abnormalities, coagulation disorders and high-lactate dehydrogenase. Dengue cases infected with Mycobacterium tuberculosis had high incidence of shock, high-hematocrit, renal function and coagulation abnormalities, which suggested a trend of more serious illness than other groups obviously. Conclusions The rate of severe disease was higher in dengue cases infected with Mycobacterium tuberculosis than those infected with hepatotropic virus, which suggests that the dengue cases infected with Mycobacterium tuberculosis should be treated timely to reduce the severity of the diseases in the hospital.
