Objective To investigate the correlation between microalbuminuria (MAU) and obesity and its indexes, including BMI, waist circumference(WC), and waist-to-hip ratio(WHR) , among partial community population in Beijing. Methods A total of 2080 subjects who took physical examination in Beijing, including 810 men and 1270 women with a mean age of(50. 9 ± 13. 1 )years, were enrolled. The informed consent has been achieved from each patients. BMI and WHR were calculated based on collected data of height, weight, WC, and hipline. Urine albumin-creatinine ratio(ACR) within the range of 30-300mg/g was classified as MAU. The subjects were divided into normal albuminuria ( NAU ) group and MAU group. The correlations between MAU and different obesity indexes including BMI, WC and WHR, were analyzed. Results Among the 2080 subjects, there was a positive correlation between BMI (r = 0. 1276,P＜0.01) and ACR, and WC (r = 0.0840, P ＜0.01) and ACR. WHR and ACR was irrelevant ( P ＞ 0. 05 ). In univariate analysis, there was significant difference in BMI ≥ 28 kg/m2 ( OR = 2. 02 ) and WC ≥85 cm (male) or≥80 cm (female) (OR = 1.69 ) between NAU group and MAU group (P ＜ 0. 05 ).There was no significant difference in BMI 24-＜ 28 kg/m2, and WHR ≥0. 90 (male) or ≥0. 85 (female)between NAU group and MAU group( P≥0. 05 ). Multivariate logistic regression analysis revealed that BMI ( OR = 1.06) was an isolated independent risk factor of MAU from age ( OR = 1.01 ), female ( OR = 1.42),systolic blood pressure (OR=1.01), TC (OR=1.93) and HDL-C (OR=0.54). Conclusions Obesity is an independent risk factor of MAU among partial community population in Beijing. The correlation between different obesity indexes and MAU also differs.

Objective To investigate whether radial augmentation index (AI) associates with cardiovascular risk as well as arterial stiffness.MethodsA total of 4985 subjects, 2417 men and 2568 women, aged 18-96 (50.9 ± 14.7)years,were recruited.AI was measured in the left radial artery using tonometry Colin HEM-9000AI.Carotid-femoral PWV (CFPWV) and carotid-radial PWV (CRPWV) were examined by automatic pulse wave velocity (PWV) measuring system.Framingham risk score and Chinese ischemic cardiovascular disease risk score were applied upon subjects without cardiovascular disease to calculate individual cardiovascular risk respectively.ResultsRadial AI (rAI) was significantly higher in women than in men[(83.18 ± 12.36)％ vs (71.93 ± 15.22)％, P ＜0.01].Simple correlation analysis showed rAI was significantly correlated to two cardiovascular risk scores or CFPWV and CRPWV.After adjusted for multi-factors, rAI was still significantly correlated to Framing, ham risk score or Chinese ischemic cardiovascular disease risk score (r = 0.17 and 0.12) in men respectively (P ＜ 0.05), while r were 0.09 and 0.08 in women respectively (P ＜ 0.05).In multivariate analysis, there was a significant association between CFPWV and rAI (r = 0.14 in men, r = 0.10 in women, P ＜ 0.01), whereas the relation ship between CRPWV and rAI was not found.The relationship between rAI and cardiovascular risk or PWV became weaker for those aged above 50 years.ConclusionAugmentation index might be a useful marker of cardiovascular risk and arterial stiffness, which could be more feasible for younger subjects as a tool for risk differentiation.

There were negative correlation between mFS and RWTr=-0.42, P<0.05) and positive correlation between mFS and LVMI r=-0.67, P<0.01).Conclusion mFS is a valuable parameter compared with traditional parameteres such as EF and FS. There is a linear association between parameteres of ventricular remodeling and systolic function assessed by mFS in early stage of hypertension.

ObjectiveTo establish the time-resolved fluoroimmunoassay (TRFIA) method for the detection of serum galectin-3 and investigate the clinical value of serum galectin-3 for the diagnosis of pancreas cancer.MethodsMonoclonal anti-human galectin - 3 antibody and biotinylated polyclonal antibody were used to establish the sandwich TRFIA for detection of serum galectin-3.The optimal experimental condition was studied.Serum levels of galectin-3,CEA and CA19-9 in the patients with pancreatic cancer,benign pancreatic mass,pancreatitis,and healthy controls were measured.The diagnostic value of serum galectin-3,CEA and CA19-9 for pancreas cancer was studied.ResultsThe linearity of the TRFIA for detection of serum galectin3 tanged between 0 to 100 μg/L.The within-run CV and between-run CV were ≤6.45％ and ≤8.68％,respectively,and the average recovery was 106.6％.The level of serum galectin-3 was 4.93 ( 0.85 ～ 23.80) μg/L in pancreatic cancer group,which were significantly higher than those in benign pancreatic mass [2.83 ( 2.17 ～ 4.06) μg/L ],pancreatitis [ 2.62 (0.55 ～ 9.76 ) μg/L ],and healthy controls group [ 1.88 ( 0.59 ～ 3.94) μg/L] (P ＜0.05).By using 3.77 μg/L as the cut-off point,the smsitivity,specificity for the diagnosis of pancreatic cancer was 75.5％ and 90.9％.The levels of Gal 3 and CEA,CA19-9 was not correlated ( r =0.1321,P =0.3761 ; r =0.0920,P =0.5384).Combined determination of galactin-3 and CEA,CA19-9 levels could increase the diagnostic sensitivity to 92％.ConclusionsTRFIA method for the detection of galactin-3 is sensitive and stable.Galectin-3 could be a potentially novel serum tumor marker of pancreatic cancer.

Objective To study the value of serum galectin-3 detected by nanomagnetic beads sorting time resolved fluoroimmunoassay (TRFIA) tandem analysis in the diagnosis of pancreatic cancer.Methods The serum of 88 cases of pancreatic cancer,50 cases of acute pancreatitis,10 cases of pancreatic cysts,and 20 cases of healthy volunteers as control were collected.First,galectin-3 antibody coupled nanomagnetic-beads was used to sort the semm,then TRFIA was applied to detect the level of galectin 3,and the result was compared with that of routine TRFIA.ROC curve was constructed to determine the cutoff value and sensitivity for pancreatic cancer diagnosis.Results The method of nanomagnetic beads sorting TRFIA detected the level of galectin 3 between O.78 and 100 ng/ml in a linear manner,the intra-CV was ≤6.38％,and inter-CV was ≤7.22％,and average recovery rate was 105.3％.The serum level of galectin-3 in control group by nanomagnetic beads sorting TRFIA was 0.38 (0.02 ～ 3.06) ng/ml,which was significantly higher than that detected by routine TRFIA [0.18 (0.00 ～ 2.64) ng/ml,P =0.000).The serum levels of galectin-3 by nanomagnetic beads sorting TRFIA in pancreatic cancer,acute pancreatitis,pancreatic cysts and healthy volunteers were 4.85(0.00 ～42.67),0.69(0.00～ 13.62),0.70(0.00 ～ 14.54),0.38(0.02 ～ 3.06) ng/ml,and the level of galectin-3 in pancreatic cancer was significantly higher than that in acute pancreatitis,pancreatic cysts and healthy volunteers group (P ＜0.01),while the difference among the other three group was not significantly different.The AUC of galectin-3 for pancreatic cancer was 0.851 ± 0.040,95％ CI:0.772 ～ 0.929.While using 1.07 ng/ml as the cut-off value,the positive rates for the diagnosis of pancreatic cancer,acute pancreatitis,pancreatic cysts and healthy volunteers were 84.1％ (74/88),34.0％ (17/50),20.0％ (2/10),10.0％ (2/20),and the sensitivity for diagnosis of pancreatic cancer was significantly higher than those in other 3 groups (P ＜ 0.01).Conclusions Nanomagnetic beads sorting TRFIA tandem analysis method can enrich serum galectin-3,and increase the sensitivity of detection for pancreatic cancer and enhance the diagnostic value of galectin-3 for pancreatic cancer.

Objective To explore the expression of calcium binding protein (S100A11) and its clinical significances in human hepatocellular carcinoma (HCC) tissue and blood plasma. Methods The expressions of S100A11 in 46 cases of HCC tissues and their paracancerous tissues were detected by immunohistochemistry. The relationship between S100A11 expression level in HCC tissues and clinical parameters was analyzed. The S100A11 expression levels in blood plasma of HCC patients (62 cases), liver cirrhosis patients (32 cases), chronic hepatitis patients (30 cases) and healthy subjects (30 cases) were detected. The sensitivity and specificity of S100A11, alpha fetoprotein (AFP) and γ-glutamyl transpeptidase Ⅱ (GGT-Ⅱ ) in HCC diagnosis were compared. Results The positive rate of S100A11 in HCC tissue (78. 3%) was significantly higher than that in paracancerous tissues (19. 6%) (P<0. 05). The expression level was correlated with the degree of differentiation, the lower differentiation degree with the higher expression level. According to ROC curve, if the cutoff points for diagnosis was set at 7. 3 μg/L, the positive rate of S100A11 in HCC patients blood plasma was 30. 6% , which was significantly higher than that in the blood plasma of patients with liver cirrhosis, patients with chronic hepatitis and healthy persons (P<0. 05). There was no correlation between S100A11 and AFP or GGT-Ⅱ in the blood plasma of HCC patients. These three indicators were complementary in HCC diagnosis, and the diagnostic sensitivity increased to 84.5% with combined detection. Conclusions S100All may be related to HCC genesis and development. The HCC diagnostic sensitivity may be increased with combined detection of S100All ,AFP and GOT- Ⅱ.

Objective:To explore the expression of C-terminal binding protein 2 (CtBP2) in human esophageal carcinoma and its relationship with clinicopathological parameters and survival. Methods:The expression levels of CtBP2 in eight cases of fresh frozen specimens of esophageal squamous cell carcinoma (ESCC) and the adjacent esophageal tissues were detected by Western blot. Immuno-histochemistry was used to detect CtBP2 expression in 90 samples of ESCC tissues and adjacent non-tumor tissues. Based on patient in-formation and follow-up data, the correlation of CtBP2 expression with patients' clinicopathological characteristics and overall survival was further evaluated using Fisher's exact test and Kaplan-Meier method, respectively. Results: Immunohistochemistry and Western blot analysis showed that CtBP2 expression in tumor tissues was higher than that in adjacent non-tumor tissues. CtBP2 expression was significantly correlated with histologic grade (P=0.002) and depth (P=0.032). Kaplan-Meier analysis demonstrated that high CtBP2 ex-pression was correlated with a short survival time. Conclusion:CtBP2 expression was upregulated in ESCC tissues, indicating that it may play a role in the oncogenesis and development of ESCC.
