Objective To investigate the relationship between the serum ghrelin level and β-cell function after treatment of patients with newly diagnosed type 2 diabetes mellitus.Methods 34 patients with newly diagnosed type 2 diabetes mellitus were divided into three groups of pre-treatment(DM0),two weeks after treatment(DM1)and six months after treatment(DM2).Intravenous glucose tolerance tests(IVGTT)were performed and blood glucose,HbA1C,ghrelin,insulin were measured during the study.Insulin sensitivity was assessed by homeostasis model assessment(HOMA).Results(1)Compared with DM0 group,beta-cell function and the mean AUC of insulin were dramatically improved in groups of DM1 and DM2(all P<0.05).(2)Compared with DM1 and DM2,ghrelin levels and the mean AUC of ghrelin in DM0 groups were lower(all P<0.05).(3)Only positive correlation between ghrelin and HOMA-β(r=0.446,P<0.05),and negative correlations of ghrelin with glucose(r=-0.274,P<0.05),insulin(r=-0.35,P<0.05)and BMI(r=-0.276,P<0.05)were found after six months of treatment.Conclusions Ghrelin might play an important role in the pathogenesis and progress of type 2 diabetes mellitus.

Objective To carry out a pharmacokinetic evaluation of oral FK506 in 13 patients after renal transplant. Methods 13 patients after renal transplantation were given prograf based immunosupressive regimen 24 hours after surgery.Blood samples to determine FK506 levels were drawn in heparinized tube at 0、20、40、60、90 min and 2、3、6、8、10 hours after the first oral dosing.The whole blood concentrations were measured by MEIA and the pharmacokinetic parameters were calculated by 3P87 program.The FK506 doses were recorded in detail for the first month. Results Cmax was (13.6259?4.1117)ng/ml;T(peak) was (1.4866?1.0725)h;t1/2 ? was (0.7749?0.7791)h,t1/2 ? was (10.7267?10.4926)h;AUC was (91.0415?40.7694)ng?ml -1 ?h -1 ,CL was (0.046?0.0036)ng?ml -1 ?h -1 and MRT was (8.1540?4.2937)h.AUC was negative correlateld with prograf dose in the first month posttransplant (r=-0.53, P =0.038). Conclusions The absorption of oral administration of FK506 was rapid in patients after renal transplantation,and can achieve Cmax in (1.5?1.1)h,the mean half life time being 10.7 h.The pharmacokinetic parameters can be the guideline for FK506 application.

Objective To investigate the relationship between the serum ghrelin level and ?-cell function after treatment of patients with newly diagnosed type 2 diabetes mellitus.Methods 34 patients with newly diagnosed type 2 diabetes mellitus were divided into three groups of pre-treatment(DM0),two weeks after treatment(DM1)and six months after treatment(DM2).Intravenous glucose tolerance tests(IVGTT)were performed and blood glucose,HbA1C,ghrelin,insulin were measured during the study.Insulin sensitivity was assessed by homeostasis model assessment(HOMA).Results(1)Compared with DM0 group,beta-cell function and the mean AUC of insulin were dramatically improved in groups of DM1 and DM2(all P

Objective:To explore the mediating effect of self-nursing ability between living condition and anxiety in the patients with peptic ulcer caused by helicobacter pylori.Methods:By using questionnaire survey method,300 patients with a peptic ulcer caused by helicobacter pylori were assessed with the exercise of self-care agency (ESCA),Self-rated Health Measurement Scale (SRHMS) and Self-Rating Anxiety Scale (SAS).The result was compared with that of 300 healthy crowd whose general condition was well-matched.The data were processed and analyzed by using SPSS13.0 and AMOS7.0.Results:The total scores of the ESCA,SRHMS and SAS were (101 ± 13),(299 ±35),(56 ±8) respectively.The result of the correlation analysis showed there were varying degree correlation among the disease self-nursing ability,self-rated Health,and anxiety (Ps ＜ 0.01).Bootstrap test showed the size of the mediating effect of self-test health to anxiety was 0.17,the 95％ confidence intervals was 0.11-0.26,and the ratio of the mediating effect to the total effect was 0.44.Contusion:It suggests that self-nursing ability may have much strong mediating role between health condition and anxiety.

A total of 1512 adult inhabitants were randomly recruited in Zhaiji district of Guiyang city in September2009.The levels of triglyceride (TG),systolic blood pressure,diastolic blood pressure,and the prevalences of abdominal obesity and hypertension increased significantly in the subclinical hypothyroidism group conpared to the euthyroid group (P＜0.05).The prevalences of high TG,low high density lipoprotein-cholesterol,and metabolic syndrome (MS) in the subgroup Ⅳ were higher than the subgroup Ⅰ (P＜0.05).Correlation analysis revealed that TSH was positively related to TG (P＜0.05).Logistic regression demonstrated that TSH was a risk factor for MS.Either in the euthyroid or total subjects serum TSH levels in the MS group were significantly higher than those in non-MS group(P＜0.05).

This article introduces definitions of three special tests, namely, non-inferiority test (to verify that the efficacy of the experimental drug is clinically not inferior to that of the positive control drug), equivalence test (to verify that the efficacy of the experimental drug is equivalent to that of the control drug) and superiority test (to verify that the efficacy of the experimental drug is superior to that of the control drug), and methods of sample size estimation under the three different conditions. By specific examples, the article introduces formulas of sample size estimation for the three special tests, and their SAS realization in detail.
