RESUMO
Objective To explore the significance of changes of serum adiponectin and testosterone levels in old male patients with type 2 diabetes mellitus(T2DM) and coronary heart disease(CHD).Methods A total of 122 male patients(more than 60 years old)were enrolled into this study,T2DM patients without CHD(T2DM group,n =40);T2DM patients with CHD (CHD group,n=38);control group(n=44,44 cases of physical healthy men over the age of 60 in Qinghai Provincial People's Hospital from November 2014 to September 2015).The serum of fasting blood-glucose,glycosylated hemoglobin(HbAlc) and blood lipid were detected by Roche cobas 800 full automatic biochemical analyzer,the serum concentration of testosterone(T) was determined by the chemiluminesent immunoassay,serum adiponectin(APN)levels were determined by the enzyme linked immunosorbent assay,the serum insulin(FINS)levels were evaluated by chemiluminescence method,according to the steady-state model evaluation method for calculation of insulin resistance (HOMA-IR),the difference among the three sets of the above indexes indicators were compared,and the correlation between APN and other indicators above were analyzed.Results Compared with control group,the serum T and APN levels in the T2DM group and CHD group were significantly decrease,and the CHD group was the most obviously (P＜0.05).Compared with control group,the FPG,FINS,triglycerides(TG),low density lipoprotein cholesterol(LDL-C)and homeostasis model assessment-insulin resistance (HOMA-IR) levels in T2DM group and CHD group were apparently higher,and the CHD group was the most obviously (P＜ 0.05).The serum adiponectin was negative correlated with TG (r=-0.363),LDL-C(r=-0.417),HOMA-IR(r =-0.602),while positively correlated with HDL-C(r=0.485),T(r=0.624).The serum T was negative correlated with LDL-C(r=-0.457),HOMA-IR(r-0.643),while positively correlated with HDL-C(r=0.478),P＜0.05.Conclusion The level of the serum APN and the serumtin T2DM patients with CHD are significantly lower than the patients without CHD,the serum adiponectin and the serum testosterone may promote the development of T2DM with CHD.
RESUMO
Objective To investigate the association between gene polymorphism of cytotoxic T lymphocyte-associated antigen-4 (CTLA-4) and Graves ophthalmopathy (GO) in Qinghai Han population.Methods Ninety cases of Graves disease were selected from June 2011 to February 2014 in The People's Hospital of Qinghai Province,and the 90 patients were divided into two subgroups according to GO (49 cases) and GD without GO(41 cases).Then the genotype and allele of CTLA-4 exon 1 (+ 49A/G) were detected in surum by the method of polymerase chain reaction restriction fragment length polymorphism (PCR-RFLP).Results The distribution of CTLA-4 exon 1 (+ 49 A/G) genotype frequencies (AA,AG,GG) was not different between GO and GD without GO subgroups [4.1％ (2/49) to 7.3％ (3/41),44.9％ (22/49) to 61.0％ (25/41),51.0％ (25/49) to 31.7％ (13/41),Fisher exact probability,P =0.180 ＞ 0.05]; the distribution of CTLA-4 exon 1 (+ 49A/G) allele frequencies (A,G) was not different between GO and GD without GO subgroups [26.5％ (26/98) to 37.8％ (31/82),73.5％ (72/98) to 62.2％ (51/ 82),x2 =2.622,P＞ 0.05].Conclusion CTLA-4 gene exon 1 (+ 49A/G) may not be a candidate susceptibility gene for Qinghai Han GO.
