Background Rare studies on the effect of statin on early stage of atherosclerosis have been repor- ted.Oxidative stress induced endothelial dysfunction may be the initiative factor for the development of atheroscle- rotic plague.Objective To investigate the mechanisms by which simvastatin,prevents atheroselerosis independ- ently of its lipid-lowering effect in Apolipoprotein E deficient mice.Methods Twenty-four 6 week old male apoE- deficient mice were randomly to receive placebo or simvastatin 5 mg/(kg?d)by gavage for 4 weeks.Total choles- terol(TC),super oxide dismutase(SOD),malondialdehyde(MDA)and serum nitric oxide(NO)were measured by biochemical analysis.Endothelium was observed by HE dyeing.The expression of caveolin-1 in aortic wall was detected by immunohistochemistry.Results There was no significant difference in serum TC between control and simvastatin treatment groups.Simvastatin caused less damaged endothelium(33.33% vs control's:75%,P

Objective:To investigate the effect of metformin and arsenic trioxide on KG1a cells proliferation of acute myeloid leukemia and its possible mechanism.Methods:CCK-8 method was used to detect the killing effect of metformin,arsenic trioxide and combined application on KG1a cells.Annexin V-FITC/P1 Dual Stain Flow Cytometry was used to detect the effect of combined application on apoptosis of KG1 a cells.Western blot was used to detect the expression of intracellular apoptosis-,autophagy-related protein.Results:Metformin and arsenic trioxide alone or in combination could inhibit the proliferation of KG1 a cells and induce apoptosis of KG1 a cells,and the proliferation inhibition rate and apoptosis rate in the combined drug group were higher than those in the drug group alone(P<0.05).The combination of drugs induced upregulation of Caspase 8 protein and P62 protein expression and was higher than that in the drug group alone(P<0.05).Conclusion:Metformin can synergize with arsenic trioxide to kill KG1a cells,and its mechanism of action may be related to inducing apoptosis and enhancing autophagy.

In order to develop characteristic folk medicine resources in Jiangxi, a pharmacognostical study was systematically performed for four different origin plants of Sikuaiwa, the result of study provides the microscopic features of powder and tissue of the crude drug. The research provided reference for the identification of Sikuaiwa, as well as a theoretical basis for the further development and the formulation of quality standards.

OBJECTIVETo evaluate the clinical therapeutic effect of electric acupuncture (EA) at Sishencong (EX-HN 1) on insomnia.
METHODSTwo hundred and seventy-six patients were randomly assigned to 2 groups, 138 in each group, the EA group treated with EA at Sishencong, and the control group with oral administration of Tianmeng Capsule. The treatment course for both groups was 3 weeks. The quality and related parameters of sleep before and after treatment were evaluated with a multi-channel sleep detector.
RESULTSAfter treatment, the quality of sleep was improved in both groups (P < 0.05), as compared with before treatment, the difference in related parameters was significant respectively (P<0.05 or P <0.01), however, the improvement in the EA group was superior to that in the control group (P < 0.01).
CONCLUSIONEA at Sishencong has obvious effect on insomnia.

Objective To explore whether the change of S phase kinase-associated protein 2 (Skp2) expression could regulate mesangial cell proliferation. Methods Skp2 siRNA and control siRNA, pIRES-GFP-Skp2 plasmid and pIRES-GFP plasmid were designed and synthesized. Cell transfection was performed by Lipofectamine 2000. Skp2 mRNA and protein levels were detected by semiquantitative PCR and Western blotting respectively. Primary culture rat mesangial cells were divided into 6 groups: 0%FCS, 20%FCS, 10%FCS+pIRES-GFP plasmid, 10%FCS+pIRES-GFP-Skp2 plasmid, 20%FCS+control siRNA, 20%FCS+Skp2 siRNA. Cell number was detected by MTT. S phase entry was measured by BrdU labeling. Cell cycle profile was determined by flow cytometric analysis. Results Skp2 mRNA level was significantly down-regulated by Skp2 siRNA compared to control siRNA. Skp2 protein level increased after pIRES-GFP-Skp2plasmid transfection compared to pIRES-GFP plasmid. MTT, BrdU labeling and cell cycle profile demonstrated that cell number (A: 0.419±0.088 vs 0.305±0.036, P<0.01) and S-phase cells (BrdU labeling positive cell: 0.21±0.04 vs 0.15±0.03, P<0.01;S-phase cell number:20.18±0.64vs 14.33±0.37, P<0.01) obviously increased after Skp2 plasmid transfection, while decreased after Skp2 siRNA transfection compared to control groups (A: 0.328±0.069 vs 0.482±0.133, P<0.01;BrdU labeling positive cell: 0.17±0.01 vs 0.24±0.00, P<0.01; S-phase cell number: 16.52±0.75vs 23.81 ±1.25, P<0.01). Conclusion Over-expression of Skp2 stimulates mesangial cell proliferation while down-regulated expression of Skp2 inhibits mesangial cell proliferation.

Objective To detect the levels of 25-hydroxyvitamin D3 and analyse the related clinical factors in patients with chronic kidney disease (CKD).Methods Patients with CKD in our department from March 1st to July 1st were enrolled continuously.The level of 25-hydroxyvitamin D3 and intact parathyroid hormone(iPTH) were detected by electrochemiluminescence and immunochemiluminescent respectively.Serum calcium,phosphorus and albumin were measured by automatic biochemical instrument.Results 127 patients were selected and the average age was (60.9?15.3).The mean level of 25-hydroxyvitamin D3 was (12.06?6.41)?g/L.82.6% patients had vitamin D deficiency and 96.9% patients had vitamin D insufficiency.The level of 25-hydroxyvitamin had no statistics difference D3 between stage 1,2 and 3 CKD patients but was much hihger than that of stage 4 and non-haemodialysis stage 5 patients.The level of 25-hydroxyvitamin D3 was not related to serum calcium,phosphorus and iPTH,while positively related to albumin and eGFR and negatively related to serum creatinine and total cholesterol.Conclusion Vitamin D deficiency and insufficiency are frequent in CKD patients and deteriorate with the progress of kidney function impairment.The level of 25-hydroxyvitamin D3 is not related to the traditional CKD-MBD index such as serum calcium,phosphorus and iPTH.
