Clinical Significance of Serum Level of Cyclopropaneoctanoic Acid 2-Hexyl in Patients with Hypertriglyceridemia-Related Disorders / 现代检验医学杂志

Objective To observe the serum level of cyclopropaneoctanoic acid 2-hexyl (CPOA2H) in patients with hypertrilyceridemia-related disorders,and investigate its clinical significance.Methods 53 obese patients (Obese group),62 obese patients after a 3 month low calorie diet (Obese patients after low calorie diet group),46 patients with chronic kidney disease (CKD group),and 60 healthy controls (Control group) were collected from Mar 2013 to Dec 2015 in Shaanxi Provincial People's Hospital.Gas chromatography-mass spectrometry (GC-MS) were used to detect the serum fatty acid and CPOA2H level in four groups.Results Ages,body mass index (BMI),C-reaction protein (CRP),total cholesterol (TC),triacylglycerols (TAG) among four groups had significant difference (F=6.85 ～ 25.36,P＜0.05).Most saturated fatty acid (14 ∶ 0,16 ∶ 0) and monounsaturated fatty acid (14 ∶ 1,16 ∶ 1,18 ∶ 1,20 ∶ 1) in obese group were higher than controls (F=3.251～7.351,P＜0.05).The polyunsaturated fatty acid (18 ∶ 2n-6,20 ∶ 4n-6) in CKD group were lower than controls (F=4.351 ～6.251,P＜0.05).There existed significant difference of serum levels of CPOA2H among four group (F=19.95,P=0.005).Serum level of CPOA2H in control (r=0.63,P=0.033) and CKD group (r=0.61,P=0.044) were positively related with TAG.Serum level of CPOA2H in obese group and obese patients after low calorie diet group were positively related with TC (r=0.70,P=0.011;r=0.48,P=0.021) and TAG (r=0.75,P=0.024;r=0.72,P=0.018).Conclusion Hypertrilyceridemia-related disorders,such as obesity and CKD,presented with elevated serum levels of CPOA2H,it suggested that serum level of CPOA2H is positively related to serum TAG concentration rather than BMI.

Relationship between artesunate influence on the process of TGF-beta1 induced alveolar epithelial cells transform into mesenchymal cells and on idiopathic pulmonary fibrosis / 药学学报

This study is to investigate the effect of artesunate on transforming growth factor-beta1 (TGF-beta1) induced epithelial-mesenchymal transition (EMT) and its possible mechanism. After the in vitro cultured RLE-6TN cells were treated with TGF-beta1 then artesunate intervened on it, after 24 h, expression of the markers of mesenchymal cell was assayed using Western blotting and real-time PCR analysis. Western blotting was also used to detect the effect of TGF-beta1 on the Smad3 and Smad7 expressions of RLE-6TN cells. Morphological alterations were examined by phase-contrast microscope, and ultrastructure changes by electron microscope. Incubation of RLE-6TN cells with TGF-beta1 resulted in the up-regulation of the expression of the mesenchymal cell markers, after artesunate intervened on it, resulted in the down-regulation of the expression. Meanwhile, incubation with artesunate intervened on RLE-6TN cells could lead to the apparent down-regulation of the expression of Smad3 and up-regulation of Samd7 and the transition of RLE-6TN cells to mesenchymal-like by TGF-beta1 induction, after artesunate intervened on it, RLE-6TN cells to epithelial-like. TGF-beta1 induced epithelial-mesenchymal transition process; artesunate can inhibit TGF-beta1-induced epithelial-mesenchymal transition process, the possible mechanism is up-regulation of the expression of Smad7 and down-regulation of the expression of Smad3, meanwhile inhibits phosphorylation of Smad3.

CLONING OF FULL CRY1C GENE FROM B.T.C.AND EXPRESSION IN CROPS BENEFICIAL BACTERIA BACILLUS CEREUS / 微生物学通报

Specific primers 1CaA/1CaB for full cry1C gene in Bacillus thuringiensis subsp.colmeri strain 15A3 were designed. The 4.0kb PCR product included the whole ORF and regulation region of cry1C gene. This PCR product was linked with shuttle vector pHT315 by two cloning steps. The recombined plasmid pHT-1C was electroporated into Bacillus cereus 9509, a kind of bacteria that beneficial to crops. The transformant could produce bipyramidal-shaped parasporal inclusions. The 60kD protein band was detected by SDS-PAGE. The bioassay result showed that the cry1C gene transformant of Bc 9509 had insecticidal activity to Spodoptera exigua.
