Objective@#The relationship between serum uric acid (SUA) levels and glycemic indices, including plasma glucose (FPG), 2-hour postload glucose (2h-PG), and glycated hemoglobin (HbA1c), remains inconclusive. We aimed to explore the associations between glycemic indices and SUA levels in the general Chinese population.@*Methods@#The current study was a cross-sectional analysis using the first follow-up survey data from The China Cardiometabolic Disease and Cancer Cohort Study. A total of 105,922 community-dwelling adults aged ≥ 40 years underwent the oral glucose tolerance test and uric acid assessment. The nonlinear relationships between glycemic indices and SUA levels were explored using generalized additive models.@*Results@#A total of 30,941 men and 62,361 women were eligible for the current analysis. Generalized additive models verified the inverted U-shaped association between glycemic indices and SUA levels, but with different inflection points in men and women. The thresholds for FPG, 2h-PG, and HbA1c for men and women were 6.5/8.0 mmol/L, 11.0/14.0 mmol/L, and 6.1/6.5, respectively (SUA levels increased with increasing glycemic indices before the inflection points and then eventually decreased with further increases in the glycemic indices).@*Conclusion@#An inverted U-shaped association was observed between major glycemic indices and uric acid levels in both sexes, while the inflection points were reached earlier in men than in women.

<p><b>OBJECTIVE</b>To investigate the relationship between the polymorphic (AT)n repeats in 3ountranslated region of exon 4 of CTLA4 gene [CTLA4(AT)n] and Graveso disease (GD) in Zhuang nationality population of Guangxi province.</p><p><b>METHODS</b>The studied groups comprised 48 patients with GD and 44 normal controls. Amplification of target DNA was carried out by polymerase chain reaction (PCR). The amplified products were run by 8% polyacrylamide gel electrophoresis, and then followed by 0.1% silver staining. Some of amplified products were sequenced directly.</p><p><b>RESULTS</b>Nineteen alleles of CTLA4 gene microsatellite polymorphism were found in Guangxi Zhuang nationality individuals. The 106 bp long allele was apparently increased in patients with GD of Zhuang nationality but not in healthy controls (P< 0.05).</p><p><b>CONCLUSION</b>CTLA4 gene microsatellite polymorphism is strongly associated with Graveso disease in Zhuang nationality population of Guangxi province. CTLA4(AT)n 106 bp may be the susceptible gene in GD patients of Zhuang nationality in Guangxi; 19 alleles of CTLA4 gene microsatellite polymorphism were found in Guangxi Zhuang nationality individuals.</p>

<p><b>OBJECTIVE</b>To investigate the postburn dynamic changes in the hypothalamus-pituitary-adrenal hormones in severely burned patients.</p><p><b>METHODS</b>Fifty burn patients were enrolled in the study. The plasma contents of total GC (cortisol), ACTH and aldosterone (ALDO) and urinary contents of 17-OHO and 17-KS were determined with radio-immunological assay (RIA) method after burn injury to compare with the normal values which were well established clinically.</p><p><b>RESULTS</b>The postburn plasma and urinary contents of the above indices were increased evidently with two peak values in shock and infectious stages, whilst the majority of he indices were lower than the normal values after 6 postburn weeks (PBWs). The values of these hormones were the lowest in dying patients. On the other hand, the values approached normal levels in those patients whose burn wounds were healing.</p><p><b>CONCLUSION</b>Increases of the plasma and urinary levels of hypothalamus-pituitary -adrenal hormones in severely burned patients were constantly seen. Burn shock and infection seemed to be the two major factors in inducing postburn stress reaction in burn victims. Abrupt decrease of the hormone levels in plasma and or urine indicated adrenal failure predicting a poor prognosis of the burn patients.</p>

Objective To investigate the prevalence of metabolic syndrome(MS)and its components among people aged over 15 years in Guangxi Zhuang Autonomous Region and to compare the difference between Zhuang and Han populations.Methods Adopting cluster sampling,a survey of diabetes mellitus was conducted in Guangxi from 2003 to 2005.A total of 27 240 subjects aged over 15 years with complete data,including background information of each individual,blood pressure,lipid profile,plasma glucose,blood uric acid and fasting insulin were analyzed in this study.The prevalence of MS and its components were analysed in Han and Zhuang Chinese in Guangxi.The criteria of International Diabetes Federation(IDF)in 2005 and the China Diabetes Society(CDS)in 2004 were applied for diagnosis.Results(1)The crude prevalence rates of MS according to IDF definition were 13.15%in total,12.41%in male and 14.11%in female respectively.The age- standardized prevalence rates of MS(according to the population composition in China in 2000)were 7.66%in total,7.26%in male and 8.81%in female.The crude prevalence rates of MS according to CDS definition were 10.75%in total,13.45%in male and 7.28%in female respectively and the age-standar-dized prevalence rates of MS were 5.9%in total,7.21%in male and 4.31%in female.The prevalence of MS in total,male and female was increasing with age(P

Objective To investigate the expressions of human telomerase reverse transcriptase(hTERT) mRNA and protein in pheochromocytoma and paraganglioma and their significance as diagnostic markers in predicting the biological behaviour of these tumours.Methods Expression of hTERT mRNA was determined by in situ hybridization in 45 pheochromocytomas/paragangliomas(31 benign,7 suspected malignant and 7 malignant) and 9 normal adrenal medulla samples,hTERT protein was determined by immunohistoebemistry.Results hTERT mRNA was expressed in 5/7 malignant turnouts and 5/7 suspected malignant tumours as compared with 3/31 benign tumours(P
