OBJECTIVE: To observe the renal protective effects of ramipril and atorvastatin used in combination or alone for diabetic nephropathy. METHODS: 54 patients were randomly assigned to receive ramipril 5 mg q.d (Group A), atorvastatin 10 mg q.d (Group B) or ramipri 5mg qd + atorvastatin 10mg q.d (Group C) for 18wk. RESULTS: After 18-week treatment, levels of both urine protein and blood lipid decreased in all the three groups (P0.05). CONCLUSION: Either Ramipril or Atorvastatin alone had satisfactory effect on diabetic neph-ropathy, but a more remarkable protection effect on kidney was noted when they used in combination.

Objective To study the protective mechanism of lycopene by its modulating lipid disturbance.Methods To make high fat diet model,the groups were intragastrically administered different dosage of lycopene at the same time.The lipids of serum and liver were measured.The pathological changes in liver were observed by HE staining method.Results Serum and liver TC,TG,LDL-C,AI levels in the three lycopene groups notably decreased(P

Aim To investigate the anti-EAC breast cancer effects of viable human umbilical vein endothe-lial cells ( HUVECs) vaccine. Methods Subconflu-ent HUVECs were mixed with OK432 to prepare HU-VECs-OK432 vaccine, and the anti-tumor efficacy of HUVECs-OK432 was investigated using a subcutaneous tumor model of EAC breast cancer. ELISA, splenic lymphocyte proliferation assay and cytotoxic T lympho-cytes ( CTL ) killing assay were adopted to detect the humoral and cellular immune responses after HUVECs-OK432 immunization. Results HUVECs-OK432 im-munization significantly inhibited the growth of EAC tumor in mice in the prophylactic procedures. High ti-ter of anti-HUVEC antibody was elicited by HUVECs-OK432 immunization. The proliferation activity of splenocytes from mice immunized with HUVECs-OK432 was significantly increased. T lymphocytes iso-lated from HUVECs-OK432-immunized mice were dose dependently killing HUVECs in vitro. Conclusion Strong humoral and cellular immune responses targeting HUVEC are elicited by HUVECs-OK432 immuniza-tion, which results in a significant inhibition on the growth of EAC tumor in mice.

Objective To study the protective mechanism of lycopene by modulating lipid metabolic disturbance in rats. Method The hyperlipidemic rats were induced by high fat diet and were divided into groups given different doses of lycopene. The serum total cholesterd(TC), triglyceride(TG), low density lipoprotein cholesterol(LDL-C), high density lipoprotein cholesterol(HDL-C), the hepatic lipase(HL) and lipoprotein lipase(LPL)activity in liver were tested by biochemical method, and the expression of low density lipoprotein receptor(LDL-R)in liver was detected by Western blot analyses. Results Lycopene decreased serum TC, TG, LDL-C, and the activity of LPL and HL in three lycopene groups were higher than those in model group, and the high dose group was the highest. Conclusion Lycopene may increase the lipases’activity and the expression of LDL-R, and decrease the deposit of TG and LDL in liver to prevent lipid metabolic disturbance.

Objective To evaluate the significance of serum matrix metalloproteinase-3 (MMP-3) and joint ultrasonography in assessing the activity of rheumatoid arthritis (RA) by comparing MMP-3 level and the ultrasonic 7 joints (US7) score in RA patients.Methods Serum MMP-3 level and US7 score were measured in 133 RA patients by immune turbidity and Doppler ultrasound.Synchronous 53 healthy subjects were recruited as controls.Clinical data were collected.Erythrocyte sedimentation rate (ESR),serum level of anti-cyclic citrullinated peptide (CCP) antibody,health assessment questionnaire (HAQ) and disease activity score 28 (DAS28) were measured.The level of disease activity is interpreted as remission(DAS28 ＜2.6),low(DAS 28≥2.6-＜3.2),moderate(DAS 28≥3.2-＜5.1),high(DAS28≥5.1).The discriminating validity of MMP-3 and US7 score in disease was evaluated using receiver operating characteristic (ROC) curve analysis with DAS28 as the reference standard.Results Compared with that in healthy controls [35.20(25.90,48.90) μg/L] and remission patients[33.40(22.60,678.40) μg/L],the MMP-3 level in moderate [105.1 (61.70,172.70) μg/L] and high [363.1 (161.50,475.90) μg/L]groups increased dramatically.US7 score in patients with high disease activity was significantly higher than that in other groups.The level of MMP-3 was significantly correlated with DAS28,HAQ,US7 score,yet did not have correlation with anti-CCP antibody.Serum level of MMP-3 was positively correlated with US7 score (r =0.566,P ＜ 0.001).In evaluating the disease activity,US7 score combined with MMP-3 (AUC 0.863 2) was not superior to MMP-3 alone (AUC 0.854 3),but significantly better than single US7 score (AUC 0.7643,P ＜ 0.05).Conclusions MMP-3 is an effective and simple index in evaluating RA disease activity.The combination of MMP-3 and US7 score does not further improve the efficacy to evaluate disease activity than MMP-3 alone in patients with RA.

The iodine concentration, MIT/DIT and T3/T4 ratios and peroxidase activity in thyroid of the rats fed on endemic goiter region diet of county Chefong in the Inner Mongolia Autonomous Region and control rats injected with 30% iodine oil 0.2 ml besides the same diet were investigated.The result demonstrated that the iodine concentration of thyroid was decreased with increasing of thyroid weight, and the MIT/DIT ,T3/T4 ratios in thyroid and thyroid peroxidase activity of the rats fed on endemic region diet were higher than that of control.These metabolic patterns showed that the rats fed on endemic region diet were in iodine deficient state and consistent with those rats fed on artificial low iodine diet.

Background Medical refraction after cycloplegia is the preferable choice for precise measurement of degree of refractive error.Drugs used in China for cycloplegia include atropine and tropicamide,and the use of cyclopentolate is an alternative for ophthalmologist.However,the data for the evaluation and comparison of efficacy of the available drugs in cycloplegia is still lacking.Objective This system analysis was to evaluate the difference between atropine and cyclopentolate in cycloplegia in children.Methods A systematic literature retrieval was conducted in MEDLINE,EMbase,Google residual accommodation after cycloplegia by atropine and cyclopentolate were compared.Statistical analysis was performed using the RevMan 5.1.0 software.Results A total of 7 studies were included in this meta analysis,including 6 cohort study design and 1 randomized,doubleblinded clinical trial and 1232 eyes.For retinoscopic evaluation after cycloplegia,no significant differences were found between cyclopentolate and atropine in children with hyperopia and myopia (WMD =-0.21,95％ CI:-0.47-0.06,P=0.13 ; WMD =-0.10,95％ CI:-0.36-0.15,P =0.43).For residual accommodation after cycloplegia,no significant difference was seen between cyclopentolate and atropine in ammetropic children (WMD =0.30,95％ CI:-0.10-0.71,P =0.15).Conclusions Cyclopentolate shows the same effect on the cycloplegia as atropine in children,and it can take the place of atropine in cycloplegia in childhood.

Objective To evaluate the curative effect of urokinase combined with low molecular heparin sodium in managing arteriovenous fistula embolism. Methods Toally 48 patients with arteriovenous fistula embolism treated from January 2014 to October 2015 were selected for the study, where 22 were assigned into control group and 26 as trial group according to the registration time. The former group were treated with urokinase and the latter with urokinase combined with low molecular heparin sodium. The rate of recanalization, the rate of thrombosis recurrence, and the adverse reactions were compared between the two groups. Results The recanalization rate in the trial group was higher than that in the control group (P<0.05). The rate of thrombosis recurrence in the trial group was significantly lower than that the control group. There was no statistical difference in adverse reactions between the groups. Conclusion The thrombolytic effect of urokinase combined with low molecular heparin sodium is superior to that of urokinase alone, with a higher rate of recanalization.

Objective To investigate the time and dose dependent effects of 17 β-estradiol ( E2 ) on eNOS phosphorylation and nitric oxide (NO) production from bovine aortic endothelial cells (BAECs). Methods The BAECs were cultured in 24-well flat plate.The dose dependent rapid induction of NO release by E2 in the BAECs was explored,and the non-genomic mechanism was studied. Each experiment was repeated for 3 times. The NO level was quantified by the electron spin resonance spectroscopy(ESR)method,and the phosphorylation of eNOS were determined by Western blot. Results NO release increased time dependently from BAECs after treatment with E2 at 100 nmol?L-1 at 1,5,10 and 15 min,and the effect peaked at 10 min.There were dose dependent effects of NO production as well as eNOS phosphorylation after treatment with E2 at different concentrations for 10 min,and the effect was the most obvious at the concentration of 100 nmol?L-1 .Upon treatment with equal volume of saline,E2 and actinomycin D (25 μg?mL-1 ) for 10 min,the NO release was(5.38±2.35),(10.59±3.28)and(10.68± 3.31) nmol?mg-1 ,respectively,and the eNOS phosphorylation level was 0.36±0.03,0.98±0.08 and 0.99±0.08,respectively. Compared with 0.9% sodium chloride solution,the NO release and eNOS phosphorylation were significantly increased in E2 treated cells(all P<0.05). Conclusion 17 β-estradiol at 100 nmol?L-1 induced eNOS phosphorylation as well as NO production from bovine vascular endothelial cells through non-genomic mechanism.The effect peaked at 10 minutes.
