Objective To study the association of insulin resistance ( IR ) with aortic compliance impairment in patients with essential hypertension (EH). Methods Thirty-five patients with EH and 35 healthy control subjects were enrolled. The two groups were matched by sex, age and weight Blood pressure was measured and high resolution color Doppler examination was performed. Pressure-strain elastic modulus ( EP) and stiff index were calculated to reflect the change of aortic compliance in all subjects. Fasting plasma glucose (FPG) was assayed with oxidase technique, serum fasting insulin ( Fins) was assayed with chemoluminescent technique, Calculate insulin resistance index (HOMA-IR) was calculated using FPG and FINS. Results In the EH group, Fins, HOMA-IR and EP of ascending aorta were ( 10. 15 ± 1.03) mU /L, 2. 21 ± 0. 68, (250. 79 ± 85. 52 ) kN/m2, respectively,and the stiff index( β) was 15. 60 ±7. 55. In the control group, Fins,HOMA-IR, EP and stiff index β were (6. 80 ± 3. 05) mU/L, 1. 48 ± 0. 16, (183. 90 ± 64. 65 ) kN/m2 and 10. 86 ± 4. 92, respectively. There were significant difference on these above mentioned indices between the two groups (P < 0. 05 ). In the EH group, HOMA-IR were positively correlated with the ascending aorta EP and stiff index β ( r = 0.558 and 0.601 respectively, P < 0. 05 ). Conclusions Aortic compliance impairment and IR are found in patients with EH. There is significant association of IR with aortic compliance impairment Hyperinsulinemia related to insulin resistance might be an important influential factor which promote large artery remodeling in patients with EH.

Objective To investigate the incidence and possible reasons of patients with rheumatoid arthritis (RA) who stopped taking slow-acting antirheumatic drugs (SAADs).Methods Two hundreds and twenty-four in-or out-patients with RA were prospectively followed up for 4-year,and their demographic and clinical information and reasons of SAADs cessation were recorded.The difference between patients who stuck to SAADs and those who stopped SAADs and the factors that resulting the cessation were analyzed.Results ① Fourty-eight percent of 224 patients with RA ceased taking SAADs during 4-year period.② The main reasons of ceasing SAADs,provided by patients themselves,were side effects of SAADs,ineffectiveness,lack of knowledge about drugs,short of SAADs,concurrent diseases,and intention to pregnancy.③ There was significant difference in low income,poor educational status,number of tender joints,and rheumatoid factor level between the patients who stuck to SAADs and those who did not.Conclusion The high incidence of SAADs cessation in RA patients should rise concern.Both medical and patient factors contribute to the cessation.

Objective To investigate the expression level of peripheral blood mononuclear cell(PBMC)human leucocyte anti-gen G(HLA-G)in patients with hepatocellular carcinoma(HCC).Methods The HLA-G mRNA in PBMC from 44 patients with HCC,21 patients with liver cirrhosis and 40 healthy subjects were measured by reverse transcription real time fluores-cent relative quantitative PCR.Results HLA-G mRNA expression level were 1.71±0.39,1.05±0.38 and 1.01±0.47 in HCC group,liver cirrhosis group and healthy control group respectively.HCC group was higher than the other two groups, the difference was statistically significant (F=33.657,P<0.001).The survival rate of HCC patients in HLA-G mRNA high-expression group was lower than HLA-G mRNA low-expression group,the difference was statistically significant (χ2=5.972,P=0.015).Conclusion PBMC HLA-G mRNA in HCC was closely correlated with tumorigenesis.It can proviede a novel diagnosis and research tool for HCC.

AIM: To study the expression of the VEGF in single and multiple superficial transitional cell bladder carcinoma and their clinical significance. METHODS: Immunohistochemical method was used to study the VEGF in 60 cases of superficial transitional cell bladder carcinoma and in 10 cases of normal bladder tissue as control. RESULTS: High expression of VEGF in bladder carcinoma cell was observed. The expression level of VEGF in multiple superficial transitional cell bladder carcinoma was higher than that in single superficial transitional cell bladder carcinoma. The recurrent rate in the patient with VEGF high expression was more than that in the patient with VEGF low expression. CONCLUSION: The expression level of VEGF was correlated to the biological behavior of superficial transitional cell bladder carcinoma.
