ABSTRACT
Objective To investigate the correlation between BMI and insulin dose in diabetic patients after short-term continuous subcutaneous insulin infusion (CSII). Methods Three hundred patients with type 2 diabetes mellitus (T2DM) were enrolled and randomized into the normal weight (BMI < 23 kg/m2) group, overweight (BMI 23 ~ 25 kg/m2) group and obesity (BMI≥25 kg/m2) group. The metabolic and anthropometric parameters of each group were compared and the related factors which may influence insulin dose were analyzed. Results The insulin dose per weight in the overweight group or in the obesity groups was significantly lower than that in the normal weight group. Weight and BMI were negatively correlated with the insulin dose per weigh. Conclusions Differences of glycemia level , β-cell function and insulin resistance exist in Chinese type 2 diabetes patients with different BMI. The stratification of BMI should be considered before estimating the insulin dose by body weight in CSII therapy.
ABSTRACT
Objective To investigate the association between single nucleotide polymorphisms in the intron 1 of thyroid stimnulating hormone receptor gene (TSHR) and Graves' disease (GD) in the Chinese Han population from Linyi city,Shandong Province.Methods A total of 1759 GD patients and 1740 control subjects were recruited for genotyping in TSHR intron 1 with genome-wide association study (GWAS) and Taqman probe technique.At the same time,serum thyroid hormone and TSH receptor antibody (TRAb) levels of patients were determined.Results Five SNPs were selected for further replication.The rs12101261 _T was significantly associated with GD risk ( OR=1.257,95％CI 1.137-1.390,P =8.23 × 10-6 ). Logistic regression identified that rs12101261 was an independent susceptibility locus of GD ( P=1.61 × 10-3 ).Furthermore,rs12101261 _T was strongly associated with GD ( OR =1.317,95％ CI 1.171-1.481,P=4.14× 10-4 ) in TRAb positive patients,but no association in TRAb negative patients ( OR=1.056,95％ CI 0.892-1.251,P=0.524 ).Serum TRAb concentration showed remarkable difference among three genotype groups of rs12101261.Conclusions Five SNPs in TSHR intron 1 are associated with GD.rs12101261 contributes to increased GD risk independently and is associated with serum TRAb level.
ABSTRACT
Endoscopic holmium:yttrium-aluminum-garnet (Ho:YAG) laser incision is a new method applied in pediatric urology recent years. To evaluate its therapeutic efficacy on treating the pediatric patients with urethral strictures and urethral atresias, a retrospective study was performed from June 2001 to July 2005 in a total of 28 pediatric patients who underwent endoscopic internal urethrotomy using Ho:YAG laser in our center. In these patients, 25 had urethral strictures and 3 urethral atresias. Follow-up was done ranging from 2 months to 4 years to assess the treatment. Of the 28 patients, 25 (89.3%) have achieved satisfied result without complications following initial incisions. Two patients with urethral atresias and another with long lesion of stricture (> 2 cm) have postoperative stenosis (10.7%). Among the three reoccurred patients, two were successfully reoperated by Ho:YAG laser and open end-to-end anastomosis, respectively. One patient failed to follow-up. With the advantages of safety, efficacy and minimal invasion, endoscopic Ho:YAG laser incision technique could be used as a primary treatment in urethral stricture patients and is worthy to be popularized further in pediatric surgery.
