Objective To observe the effets of telmisartan on oxidative stress and the activity of protein kinase C in type 2 diabetic Rat.Methods Thirty six Wistar rate were divided into three groups as normal rats、diabetic rats and diabetic rats treated with telmisartan.Blood glucose,blood insulin,blood lipid were measured after 4,5,11 and 17 weeks,serum creatinine,blood uria nitrogen,urinary albumin excretory rate, lipid peroxidation(MDA),the activity of protein kinase C(PKC) and of antioxidant enzymes including Cu/Zn superoxide dismutase(Cu, Zn-SOD),catalase(CAT) and glutathione peroxidase(GSH-Px) in renal tissue were measured after 11 and 17 weeks.In addition,the renal tissue were observed by light microscopy.Results The blood glucose and blood insulin were found no significant difference between that in type 2 diabetic rats with and without telmisartan treatment groups.Comparing with untreated group,the level of blood lipid,serum creatinine,blood uria nitrogen,urinary albumin excretory rate, renal MDA and the activity of cell membrane PKC in telmisartan treated group were significantly decreased,but the activity of renal Cu/Zn SOD,CAT and GSH-Px was increased.There was significant correlation between the change of renal MDA and the activity of antioxidase and the activity of cell membrane PKC. Conclusion Telmisartan could inhibit oxidative stress in diabetic rats, and its mechanism perhaps was decreasing the activity of cell membrane PKC.

Objective To explore the relationship between P-selection,nitric oxide(NO),high-sensitive-C-reactive protein(hs-CRP)and type 2 diabetes mellitus(T2DM)with macroangiopathy.Methods In sernm of 125 T2DM subjects(60 subjects with macroangiopathy and 65 subjects without macroangiopathy)and 55 normal controls,the activity of P-selection,NO and hs-CRP was detected by ELISA,Nitrate Reductase Assay and scattering immunoturbidimetric method,respectivley.Results The activity of serum P-selection and hs-CRP was significantly higher in diabetic macroangiopathie group than in non macroangiopathic group and control normal.Serum NO was significantly lower in diabetic rnacroanglopathic group than in non macroangiopathic group and control normal.Serum P-selection was positively correlated with hs-CRP-systolic blood pressure(SBP),LDL-C,and was negatively correla- ted with NO:P-selection,hs-CRP,LDL-C and SBP were independently risk factors for T2DM with macroangiopathy. Conclusion Determination of P-selection and NO is very important for prevention and diagnosis of diabetic mac- roangiopathy in early stage.

A 15-year-old female patient presented with orthostatic erythema in the limbs for half a year. Skin examination revealed that diffuse reticular erythema appeared in the limbs after standing with her arms hanging down for 30 seconds, while the erythema disappeared and skin color returned to normal after raising her arms or lying flat for 30 seconds. The rash in the limbs was reproduced by inflating a sphygmomanometer cuff to 60 mmHg for 2 minutes with the limbs in the horizontal position. Antinuclear antibodies were positive at a titer of 1 ∶1 000. Histopathological examination showed dilated small vessels in the superficial dermis without obvious inflammatory cell infiltration. The patient was diagnosed with gravitational erythema.

Exosomes contain many components including variety kinds of lipids,proteins,microRNAs (miRNAs) and so on.They can transport their loaded substances to the recipient cells and play a role of biology.Exosomal miRNAs play important roles in the occurrence and development of tumors,and they are closely related to the tumor growth,metastasis,drug resistance and immune regulation.Exosomes and exosomal miRNAs can be served as reference indexes for tumor metastasis and prognosis,which provide new targets for tumor therapy.

Objective:To establish a protein-protein interaction (PPI) network of 5 microRNA (miRNA) target genes differentially expressed in the plasma of coal-burning fluoride exposed population, and to screen genes and gene modules with important roles.Methods:Five miRNA (hsa-miRNA-3131, hsa-miRNA-4516, hsa-miRNA-6501-5p, hsa-miRNA-10b-5p, hsa-miRNA-4683) target genes differentially expressed in the plasma of coal-burning fluoride exposed population screened by our previous study were mapped to the STRING online database (https://string-db.org), and the PPI network was screened. The Cytoscape v3.6.0 software was used to visualize the PPI network, the topological attribute values degree and betweenness centrality were obtained by the NetworkAnalyzer plug-in, and the central node was filtered in the network (the node with the highest degree and the highest betweenness centrality). At the same time, the maximal clique centrality (MCC) analysis method in the CytoHubba plug-in was used to determine the important nodes in the PPI network. The cluster analysis was conducted by the MCODE plug-in, and the gene modules were screened in the PPI network. The protein names contained in the gene modules were submitted online to the KOBAS v3.0 database (http://kobas.cbi.pku.edu.cn/), and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analysis was performed on the gene modules selected by the MCODE plug-in.Results:The PPI network of target genes was consisted of 1 035 nodes and 4 346 edges. The degree (101) and betweenness centrality (0.010 723 89) of ubiquitin A-52 residue ribosomal protein fusion product 1 (UBA52) were the highest, which was the central node of the PPI network. According to MCC analysis, UBA52 was an important node in the PPI network. The top 5 gene modules were selected from the PPI network, and the highly enriched gene pathways in the KEGG pathway enrichment analysis of the 5 gene modules included ubiquitin mediated proteolysis, spliceosome, endocytosis, neuroactive ligand-receptor interaction and vesicular transport.Conclusion:The PPI network of 5 miRNA target genes differentially expressed in the plasma of people exposed to coal-burning pollution of fluoride is successfully established, and the UBA52 gene and the 5 main pathways of gene modules are selected.

AIM: To investigated the effect of 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) on the expression of kinesin superfamily (KIF) genes in striatum and substantia nigra in C57BL mice. METHODS: The Parkinson's disease model was established by consecutive administration of MPTP to C57BL mice. The levels of mRNA for five kinesin superfamily genes, KIF1A, KIF2, KIF3A, KIF4, and KIF5A, in striatum and substantia nigra of mice, were estimated by RT-PCR. RESULTS: In substantia nigra, the expression of KIF genes were decreased after MPTP treatment except KIF2 that showed no significant change. However, the expression of KIF1A, KIF3A and KIF4 were increased in striatum after MPTP treatment, while the expression of KIF2 and KIF5A were similar to that in substantia nigra. CONCLUSION: The lose of dopaminergic neurons in nigrostriatal pathway after MPTP treatment may be related to the expression of KIF genes. [
