Objective To investigate the relationship between Vaspin and GDM insulin resistance. Methods The GDM preadipocyte cells were recoveried, extended and differentiated.Vaspin overexpression carriers were made to transformate, cultivate and extract the plasmid. The fat cells were transfected and extended using 4 overexpression levels (0.0 μg, 1.0 μg, 2.5 μg, 5.0 μg). Q-PCR was used to detect mRNA expression of Vaspin, insulin receptor substrate-1/2 (IRS-1/2), phosphatidy inositol 3 kinase (PI3K (P85a) Western Blot was used to detect protein expression of Vaspin, IRS-1/2, PI3K (P85a) and IRS-1/2 phosphorylation levels, and [3H]-2-deoxidation-D-glucose uptake assay was used to detecte glucose uptake rates. Results (1) According to the Q-PCR and WB results, the constructed Vaspin overexpression carrier was effective; (2) With the Vaspin expression increased, the mRNA and protein expression of IRS-1/2, PI3K (P85a) and IRS-1/2 tyrosine phosphorylation levels had no significant changes;(3) Glucose uptake rate of fat cells had no obvious correlation with Vaspin. Conclusion High expression of Vaspin in GDM serum and omental adipose tissue has no obvious link with the insulin resistance of GDM.

Objective To investigate the correlation between lipoprotein-associated phospholipase A2 (Lp-PLA2) gene R92H polymorphism and ischemic stroke and its subtype in a Chinese Han population of Shandong province. Methods A total of 386 patients w ith first-ever ischemic stroke and 368 healthy controls in China Shandong region w ere enrol ed. According to the TOAST criteria, the patients w ere further divided into large artery atherosclerosis (LAA) and smal artery occlusion (SAO). Enzyme linked immunosorbent assay w as used to detect the serum Lp-PLA2 level. Polymerase chain reaction and directly sequencing w ere used to detect R92H gene polymorphism. Results The serum Lp-PLA2 levels in the ischemic stroke group, LAA group and SAO group w ere higher than that in the control group, and there w ere significant differences (al P<0.01). The distribution frequencies of GA (P=0.006), AA (P=0.020), AA+AG (P=0.009), and A al ele (P=0.001) in the ischemic stroke group w ere significant higher than those in the control group. There w ere also significant differences in distribution frequencies of GA+AA genotype (P=0.007) and A al ele (P<0.001) betw een the LAA group and the control group, w hile the SAO group w as not the case. Multivariate logistic regression analysis showed that GA+ AA genotype (odds ratio [OR] 1.43, 95%confidence interval [CI] 1.02-2.00; P=0.029), GA genotype (OR 1.42, 95%CI 1.01-2.00; P=0.037), and A alele (OR 1.44, 95%CI 1.11-2.18; P=0.028) were the independent risk factors for ischemic stroke. GA+AA genotype (OR 1.73, 95%CI 1.18-2.55; P<0.001) and GA genotype (OR 1.67, 95%CI 1.13-2.48; P<0.001) w ere the independent risk factors for LAA, and they w ere not significantly independent correlated w ith SAO. Conclusions The serum Lp-PLA2 levels increased in patients w ith ischemic stroke, and they increased most significantly in the LAA group. The R92H gene polymorphism might be associated w ith the susceptibility of ischemic stroke in a Chinese Han population of Shandong province.

Methods Shufei in situ gel was prepared by cold cut method with poloxamer 188 (P188) and poloxamer 407 (P407) as gel base. Using gelling temperature index, the dosage range of gel matrix P407 and P188 in Shufei in situ gel was determinated by the single factor and star design-response surface methods to get the best prescription of Shufei in situ gel. The transdermal diffusion process of Shufei in situ gel was carried out in Franz diffusion cells to explore the permeation mechanism. Results The optimized prescription of Shufei in situ gel was as follow: The ratio of gel matrix to drug at 1:3, P188 dosage of 4%, P407 dosage of 22.5%, and the phase transition temperature within 32-36 ℃ to form gel. The releases of sinapine thiocyanate and genkwanin in Shufei in situ gel were all in line with the Higuchi release model. Conclusion The preparation process of Shufei in situ gel is stable and feasible with reliable product quality and good application prospect, which is suitable for industrial production and clinical application.

Objective To compare the characteristics of food and nutrition intake in type 2 diabetes mellitus (T2DM) patients with or without carotid atherosclerosis and analyze the relationship between diets/C-reactive protein (CRP) and carotid intima-media thickness (C-IMT). Methods Sixty patients with T2DM were enrolled and divided into two groups based on C-IMT: group A (C-IMT ＜ 1 mm, n=30) and group B (C-IMT≥1 mm, n=30). All subjects were investigated with questionnaires including 3-day food recall They all took somatometric measurement. Blood and urine samples were collected in all subjects to examine the levels of high sensitive-CRP,C-peptide, blood glucose, glycosylated hemoglobin, blood lipid, renal function, urine microalbumin, and other indicators. Results The intakes of vegetables, fruits, and aquatic products were significantly higher in group A than in group B ( P ＜ 0. 05 ). The intake of vitamin C in group A was significantly higher than that in group B ( P ＜0. 05 ). The levels of CRP in group B was significant higher than that in group A (P = 0. 000). Positive correlation was found between CRP level and C-IMT in T2DM patients ( r = 0. 36, P = 0. 004). Furthermore, CRP was negatively correlated with the intakes of vegetables and fruits ( r = - 0. 334, P = 0. 01 ), aquatic products ( r = -0. 315, P = 0. 016), and vitamin C ( r = - 0. 2786, P = 0. 038 ), respectively. The intake of fruits was negatively correlated with C-IMT (r, = -0. 33, P = 0. 01 ). Conclusions T2DM patients without carotid atherosclerosis intake more vegetables, fruits, aquatic products and vitamin C than those with atherosclerosis. Vegetables, fruits,sea foods and vitamin C may be the protective factors against atherosclerosis in T2DM patients. CRP is associated with the development of atherosclerosis in T2DM patients.
