Aim To investigate the protective effect of compound total flavonoids on atherosclerosis in ApoE -/- knockout mice.Methods Seven-week old C57BL/6 mice considered of the normal group (n =1 5 );seven-week old ApoE -/- mice were fed with high-fat diet and were assigned randomly into 5 groups:model group,simvastatin group,the low com-pound flavonoids group,the middle compound fla-vonoids group and the high compound flavonoids group.After 1 6 weeks,mice serum and aortas were harvested.The formation of atherosclerotic plaque was analyzed by HE staining,The serum level of lipids pro-files and superoxide dismutase (SOD )were deter-rnined.The levels of IL-1 βand NF-κB in serum were detected by ELISA assay.Results Area of atheroscle-rotic lesion was significantly less in the compound fla-vones group than in model.The level of TC,TG,LDL-C,IL-1 β,NF-κB in serum of the compound flavonoids group were decreased significantly,while SOD and HDL-C increased significantly compared with the mod-el group,and the difference was significant (P <0.05).Conclusion The compound flavonoids have a good protective effect on early atherosclerosis in mice, which may be due to its alleviating effects on hyperlipi-demia and inflammation and oxidation.

Objective:To explore the curative effect and safety of febuxosta for the patients with primary gout complicated with mild to moderate renal insufficiency.Methods:60 male patients with primary gout complicated with mild to moderate renal insufficiency were enrolled in the affiliated Hospital of integrated traditional Chinese and Westem Medicine,Nanjing University of Chinese Medicine from January 2015 to August 2016 and randomly divided into two groups,the control group (n=30) was treated by allopurinol,and the study group (n=30) was treated by febuxosta treatment.The blood uric acid (BUA) and hepatorenal function were compared in the treatment period,and the incidence of adverse reactions and the recurrence of gout in post-treatment were compared.Results:At 1,2 and 3 month after treatment,the serum level of BUN in the study group was significantly lower than that of the control group (P＜0.05).The renal function of all patients were significantly improved compared with pre-treatment (P＜0.05),but the no significant difference was found between two groups at the same time(P＞0.05).The control group showed the adverse reactions with limb discomfort,drowsiness,nausea,abdominal distension,diarrhea and itch of skin,and the study group showed limb discomfort,drowsiness and abdominal distension,and one patients presenting allergic skin rash and discontinuation of allopurinol.The total incidence of adverse reactions in the study group was significantly lower than that of the control group (P＜0.05).Conclusions:Febuxosta could effectively and safely decrease the blood uric acid levels and improve the renal function of patients with primary gout complicated with mild to moderate renal insufficiency.

Objective To investigate the effects of simvastatin on membrane ionic currents in left ventricular myocytes after acutemyocardial infarction(AML.so as to explore the ionic mechanism of statin treatment for antiarrhythmia.Methods Fourty-five NewZeland rabbits were randomly divided into three groups:AMI group,simvastatin intervention group(statin group)and sham-operatedcontrol group (CON).Rabbits were infarcted by ligation of the left anterior descending coronary artery after administration of oralisolated enzymatically from the epicardial zone of the infractcd region.Whole cell patch clamp technique was used to record mmbranewas significantly decreased in AMI group(-23.26+5.1 8)compared with CON(-42.78±5.48,P＜0.05),while it was significantlyincreased in Stating roup(-39.23±5.45)compared with AMI group(P＜0.01);The peak Ica-L current density(at 0 mV) was significantlydecreased in AMI group(-3.23±0.91)compared with CON(-4.56±1.01,P＜0.05),while it was significantly increased in Statin group(-4.18±0.95)compared with AMI group(P＜0.05);The Ito current density(at+60 mV)was significantly decreased in AMI group(10.41±1.93)compared with CON(17.41±3.13,P＜0.01),while it was significantly increased in Statin group(16.21±2.42)compared withattenuate this change without lowering the serum cholesterol level,suggesting that simvastatin reverse this electrical remodeling thuscontributing to the ionic mechanism of statin treatment for antiarrhythmia.

OBJECTIVETo investigate the relationship between hormone sensitive lipase (HSL) gene polymorphism and aerobic endurance.

METHODSThe (CA)n repeats polymorphism genotypes in HSL intro 6 of 123 outstanding long distance runners and 127 controls of Han nationality in northern China were analyzed by PCR and Fluorescence labeled STR-genescan. Repeat polymorphisms were grouped according to segmentation point and alleles were divided into long or short chains. Chi-square test was used to analyze the frequency difference of allelic and genotypic between athlete and control groups.

RESULTS(CA) n repeats polymorphism in HSL gene was total of 9 different repeat number of alleles, which composed of 25 different genotypes. The chi-square test result showed that when compared short and long chain alleles split by 4, there was a significant difference (P <0.05) of genotype distribution in 5/10 km group compared with control. Compared the rest groups with control, there was no significant difference.

CONCLUSIONCompared short and long chain alleles split by 4, the LL genotype of (CA)n of HSL was associated with aerobic endurance and it might be a molecular marker of elite 5/10 km long distance runners.

Objective To evaluate the safety and efficacy of the CT-guided percutaneous cryoablation of osteoid osteoma in children.Methods Nine children with osteoid osteoma proved by histopathology were treated with CT-guided cryoablation from January 2007 to January 2010.There were 6 boys and 3 girls.Their mean age was ( 13.0 + 1.6 ) years ( ranging from 10.0-15.0 years ).The procedures were performed under local anesthesia.Eight G bone biopsy needles for biopsy and 17 G freezing needles were used in the procedure.CT guidance was used for procedural planning,instrument guidance,and monitoring.Each cryoablation included two freezing-thawing cycles.Follow-up was performed to assess technical and clinical outcome.A visual analog scale (VAS) was used to assess severity of pain pre- and post-procedure,and mean VAS for the group was compared pre- and post-procedure with Kruskal-Wallis rank sum test.Results Biopsy and cryoablation were successfully performed in all children.No major immediate or postponed complications were observed.Significant pain relief ( P ＜ 0.01 ) was observed in all patients after procedure.The VAS of preoperation(8 points 1 case,7 points 3 cases,6 points 4 cases,5 points 1 case) compared with that of one month after operation ( 1 point 4 cases,0 point 5 cases),the difference was statistically significant( H =32.838,P ＜ 0.01 ).These patients were allowed to fully weight-bear and function without limitation 3 days after the procedure.Pain was obviously released.Pain recurrence was not observed in all patients.Moderate fever (37.8 ℃ ) was observed in a patient one day after operation and fully recovered 2 days later.Conclusion CT-guided percutaneous cryoablation is a safe and effective minimally invasive method for the treatment of osteoid osteoma in children.
