OBJECTIVE: To study the immunomodulatory effects of Astragalus polysaccharide (APS) in type 1 diabetic mice. METHODS: A mouse model of type 1 diabetes mellitus was established by intraperitoneal injection of multiple low dose streptozotocin (MLD-STZ). The diabetic mice were intraperitoneally administered 100, 200, 400 mg/kg APS or 1 ml normal saline (NS) every day respectively, then the diabetic mice were sacrificed after 15 or 30 days of treatment. The effect of APS on insulitis was determined via pancreatic histological analysis. Serum insulin autoantibody (IAA) levels were measured by radio-immunoassay (RIA). Proliferation ability of splenocytes to concanavalin A was tested by using [(3)H] thymidine incorporation assay. The levels of cytokine interferon-gamma (IFN-gamma) and interleukin-4 (IL-4) secreted by splenocytes were determined by enzyme linked immunosorbent assay (ELISA) method, and the expression of peroxisome proliferator-activated receptor gamma (PPARgamma) in spleens was characterized using Western-blot analysis. RESULTS: Attenuated insulitis, down-regulation of the serum IAA levels and Th1/Th2 cytokine ratio, decrease of the proliferation ability of splenocytes to concanavalin A, and up-regulation of the PPARgamma levels in spleens showed a significant time- and dose-dependent response to APS treatment as compared with the NS-treated group. CONCLUSION: APS possesses immunotherapeutic effects on mice with type 1 diabetes mellitus through improving the cell- and humoral-mediated immunity.

Objective To study deletion mutations and polymorphism of PINK1 gene exons in patients with Parkinson' s disease (PD) in the littoral of Zhejiang Province,and analyze the association between these changes and the etiology of PD.MethodsAll exons of PINK1 gene in 200 PD patients( 112early-onset PD and 88 late-onset PD) and 220 controls (68 young controls and 152 old controls ) were amplified by polymerase chain reaction (PCR). All the positive PCR products were sequenced,and genotypes were detected by dot blot allele and genotype frequencies of PINK1 were compared by the Chisquare test.ResultsNo deletion mutations of the exons were found in all patients and controls.However,a known heterozygote point mutation G12169A in exon 5 was identified in 2 patients with early-onset PD.And G12164A polymorphism and G12101A polymorphism were located on PINK1 gene of exon 5. There were G/G and G/A genotypes in G12164A polymorphism,no A/A genotype.There were G/A and A/A genotypes in G12101A polymorphism,no G/G genotype. The chain relation polymorphism A/A genotype frequency was significantly higher in the PD group 84/200 (42.0％ ) than the control group (52/220,23.6％,x2 =4.034,P =0.045 ).The frequency was also significantly higher in the late-onset PD (40/88,45.5％ ) than the old control (32/152,21.1％,x2 =3.951,P =0.047 ).There were no significant differences in alleles frequencies of other groups.ConclusionThe deletion mutation and point mutation are rare in PD patients in littoral of Zhejiang Province.Chain relation polymorphism at G12164A and G12101A in PINK1 gene might be a susceptible factor for PD patients.
