Background: Plasma lipids are affected not only by dietary intake and life style but also by genetic factor. Objective: To discover the relationship between plasma lipids and the presence of LPL S447X and PAF-AH V279F in the bodies of rural Vietnamese population. Subject and Method: One hundred and ninety three subjects were randomly selected from rural areas in Ho Chi Minh city. The presence of LPL S447X and PAF-AHV279F polymorphism was determined using an Invader assay, and the plasma lipid levels were measured by an enzymatic method. A profile regarding the dietary intake was also made for each subject. Result and Conclusion: The frequency of LPL 447SX/XX (12.2%) polymorphism, PAF-AH Val279Phe mutation allele frequency (5.4%) in the Vietnamese was closely similar to that of other Asian populations. LPL447X polymorphism was found to be significantly associated with a higher HDL-C level in comparison to LPL 447S. LPL S447X affects plasma HDL-C and TG concentration in Vietnamese rural population.

Systemic lupus erythematosus-related acute pancreatitis (SLEAP) has a poor prognosis with a high mortality. We described the clinical features of SLEAP, and discussed the feasibility of plasma exchange (PE) combined with glucocorticosteroids (GC) in short-term prognosis and possible mechanism in reducing serum inflammatory cytokine IL-6 and removing serum lipids. A retrospective study was performed by an independent rheumatologist. Medical records of SLEAP from March 2010 to December 2014 were retrieved from Tongji Hospital information system, and patients were divided into two groups according to whether PE therapy was adopted. Sixteen patients treated with PE in combination with GC were classified as group A, and the other 10 patients who were treated with merely GC were classified as group B. Patients' clinical remission rate and average daily GC dosage after two-week therapy were compared between the two groups. Patients' serum inflammatory cytokines and lipid concentration were compared between baseline and after two-week treatment in both groups. Pearson correlation test was performed to determine association between serum cytokines and Ranson score. SLEDAI score in group A patients at baseline (14.8±3.1) showed no statistical difference from that in group B (14.1±3.3). At baseline serum IL-6 levels had no significant difference between group A [13.14 (11.12, 16.57) mg/L] and group B [14.63 (11.37, 16.37) mg/L]; after two-week therapy IL-6 decreased significantly in group A [9.16 (7.93, 10.75)mg/L] while it did not show decreasing trend in group B [13.62 (9.29,17.63) mg/L]. Serum lipid concentration after two-week therapy in group A [(TC=5.02±0.53, TG=1.46±0.44) mmol/L] decreased significantly compared to baseline [(TC=6.11±0.50, TG=2.14±1.03) mmol/L], while similar tendency was not observed in group B. The remission rate after two-week therapy was higher in group A (70.0%) than in group B (25.0%). Acute pancreatitis (AP) was one of the clinical manifestations of active SLE. PE combined with GC could reduce serum IL-6 level, and remove serum lipid to improve short-term prognosis. Therefore, it might be a safe and effective way in treating SLEAP and was worth continuing to explore its feasibility.

OBJECTIVE: To evaluate the change of plasma level of retinol binding protein 4 (RBP4) in patients with coronary heart disease, and to explore the effect of hyperinsulinemia. METHODS: This study was carried out at Xiangya Hospital of Central South University, China, from September 2009 to May 2010. Thirty patients with coronary artery disease (the CAD group) were confirmed by coronary angiography, 29 patients with CAD plus hyperinsulinemia (the CAD+HIns group), and 30 healthy subjects were enrolled as controls (the control group). The peripheral blood sample from the anticubital vein was collected aseptically in all the subjects to measure the RBP4 by enzyme linked immunosorbent-assay (ELISA). The height, weight, body mass index (BMI) the waist-to-hip ratio (WHR), the blood pressure, the fasting plasma glucose (FPG), the fasting insulin (Fins), the 2-hour postprandial inslulin (2hPIns), and the homeostasis model assessment-insulin resistance index (HOMA-IR) was measured. The lipids, high sensitivity C reactive protein (hsCRP), uric acid(UA), free fatty acids (FFA) were all examined. RESULTS: The level of plasma RBP4 in the CAD+HIns group was higher than that in the CAD group and the control group (both P<0.01), with no significant difference of plasma RBP4 between the CAD group and the control group (P>0.05). Correlation analysis showed that the plasma RBP4 level was significantly correlated with BMI, FPG, FIns, 2hPIns, HOMA-IR, TG, HDL-C, UA, and hsCRP (r=0.259, 0.331, 0.582, 0.452, 0.600, 0.236, -0.290, 0.243, 0.231, respectively; all P>0.05). Multiple regression analysis showed that BMI, 2hPIns, and HOMA-IR were the independent factors related to RBP4. CONCLUSION The plasma level of RBP4 does not increase in the CAD group, but it is high in the CAD +HIns group. RBP4 level is related to BMI, lipids, UA, and other cardiovascular risk factors. BMI, 2hPIns, and HOMA-IR are the independent factors associated with RBP4.

Objective: To study the changes of the serum zinc alpha 2 glycoprotein (ZAG) level in men and its relationship with blood lipid male reproductive hormones. METHODS: We enrolled 297 men aged 25－ 65 years in this study, 152 with hyperlipemia (HL) and the other 145 with normal blood lipid (normal control). We divided them into four age groups (25－35 yr, 36－45 yr, 46－55 yr, and 56－65 yr) and three tertile groups (Q1, Q2, and Q3) according to the tertiles of the serum ZAG level, and examined their blood lipid, blood glucose, serum ZAG, and reproductive hormones. RESULTS: The serum ZAG level was decreased gradually with the increase of age in both the HL patients and normal controls, significantly in the 36－45 and 56－65 yr age groups (P <0.05), and markedly lower in the HL than in the control men in the 25－35 and 36－45 yr groups (P <0.05). The levels of follicle-stimulating hormone (FSH) and total testosterone (TT) changed significantly with the ZAG level. The level of serum ZAG was correlated negatively with age (r = －0.58, P<0.05), waist circumference (r = －0.21, P <0.05), body mass index (BMI) (r = －0.22, P <0.05), fasting blood glucose (r = －0.16, P <0.05) , and triglyceride (TG) (r = －0.27, P <0.05) but positively with TT (r = 0.36, P <0.05). Age, BMI and TG were independent factors influencing the serum ZAG level. CONCLUSIONS The serum ZAG level is decreased with the increase of age and associated with lipid metabolism, abdominal obesity, and reproductive hormone levels in males.

BACKGROUNDRetinol binding protein 4 (RBP4), as an adipocyte secreted cytokine, was recently found to be inversely correlated with expression of glucose transporter 4 (GLUT4) in insulin resistance (IR) state and to have an intimate relationship with IR and type 2 diabetes mellitus (T2DM). The present study aimed to evaluate the anti-diabetic efficacy of cinnamaldehyde (Cin), berberine (Ber), and metformin (Met) as well as their impacts on the RBP4-GLUT4 system.

METHODSRat models of T2DM were established by combination of intraperitoneal injection of low-dose streptozotocin and high fat diet induction. Rats were divided into five groups: the control group, the diabetes group, the diabetes + Ber group, the diabetes + Cin group, and the diabetes + Met group. Western blotting was used to detect the serum or tissue RBP4 and GLUT4 protein levels.

RESULTSAfter treatment for four weeks, both Cin and Ber displayed significant hypolipidemic, hypoglycemic, and insulin sensitizing functions (P < 0.01) compared with the control group. Their effects on lowering fasting plasma glucose (FPG), low density lipoprotein-cholesterol (LDL-C) and homeostasis model assessment of insulin resistance (HOMA-IR) seem even better than that of Met. Cin and Ber markedly lowered serum RBP4 levels and up-regulated the expression of tissue GLUT4 protein, and Cin seemed more notable in affecting these two proteins.

CONCLUSIONSBoth Cin and Ber display an exciting anti-diabetic efficacy in this study and may be of great value for the treatment of type 2 diabetes. Their mechanisms involve the RBP4-GLUT4 system, during which the serum RBP4 levels are lowered and the expression of tissue GLUT4 protein is up-regulated.
