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 explore the clinical value of renal dynamic imaging and urinary N-acetyl-?-D-glucosaminidase(NAG),apoptosis DNA fragment(ADF) in evaluating the damage degree of hydronephrotic kidneys(HnK) in children with hydronephrosis.Methods Level of glomerular filtration rate(GFR) was detected in 41 children with congenital hydronephrosis by renal dynamic imaging,and urine NAG,ADF in pelvis in HnK and healthy kidneys (as controls) were detected by enzyme-linked immuno-sorbent assay(ELISA).Patholo-gic changes of HnK in 41 children were graded intoⅠ~Ⅴ according to Elder standard. And GFR,urinary NAG and ADF of HnK were divi-ded into subgroup according to pathologic changes ,at the same time statistical analysis was performed within each groups. And the correlations of pathologic grades with GFR,urinary NAG and ADF of HnK were analyzed.Results 1.Kindneys GFR in healthy kidneys and Hnk were (174.33?20.43)?10-3 L/min,(143.86?17.51)?10-3 L/min respectinely,and there was significant difference between healthy kidneys and Hnk (P0.05).3.There was significant negative correlation between GFR levels of HnK and pathologic grades(r=-0.814 P0.05).Conclusions For hydronephrotic kidneys,urinary NAG can eva-luate impaired nephric tubule whereas renal dynamic imaging may evaluate the damage level of glomeruli;urine ADF may not indicate the damage level of diseased kidneys in children with congenital hydronephrosis.

Objective To investigate the safety and feasibility of endovascular stent angioplasty in treating symptomatic stenosis of middle cerebral artery.Methods Endovascular angioplasty with coronary stents was performed in 27 patients with symptomatic stenosis of middle cerebral artery.The clinical results were reviewed and analyzed.Results Of the total 27 patients,successful placement of the coronary stents Was achieved in 24.Angiography immediately after the procedure showed that the stenotic degree of the diseased artery was markedly decreased from preoperative (80±19)%to postoperative (8±4)%,the improvement was very obvious.Percutaneous transcatheter angioplasty had to be employed in two cases because of the failure of stent placement.A mean follow-up period of 18 months was carried out.During the following up period no transient cerebral ischemia attack occurred in 25 patients and no newly-developed cerebral infarction in region fed by the responsible vessels occurred either.Re=irrigation cerebral hemorrhage was seen in one patient,which occurred three hours after the placement of the stent.In one case the placed stent fell off and immigrated into the siphon of internal carotid artery,and the displaced stent Was took out later with a catching apparatus.In another case re-stenosis occurred six months after the stenting.Conclusion Percutaneous endovaacular stent angioplasty is a safe and effective treatment for symptomatic stenosis of middle cerebral artery,although its long-term results need to be further evaluated.

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.

Objective To evaluate the predictive value of neutrophil to lymphocyte ratio(NLR) and B-type natriuretic peptide (BNP) in elderly patients with heart failure complicated with pulmonary infection. Methods 178 heart failure patients in our hospital from June 2018 to May 2020 were selected as the research objects, and they were divided into pulmonary infection group (n=92) and non-pulmonary infection group (n=86) according to whether they were complicated with pulmonary infection. The differences of NLR and BNP levels and other clinical indicators between the two groups were compared. Univariate and multivariate Cox regression were used to analyze the influence of NLR and BNP levels on heart failure complicated with pulmonary infection. The predictive value of NLR combined with BNP on heart failure complicated with pulmonary infection was analyzed by receiver operating characteristic (ROC) curve. Results Multivariate logistic regression analysis showed that NLR (OR=7.606, 95% CI: 3.123-18.526) and BNP (OR=4.264, 95% CI: 1.682-10.811) were independent risk factors of elderly heart failure complicated with pulmonary infection after adjusting for other related variables. Pearson correlation analysis showed that BNP level was positively correlated with NLR level (r=0.400, P<0.001). The area under ROC curve of NLR, BNP and NLR+BNP in predicting pulmonary infection in elderly patients with heart failure was 0.810, 0.756 and 0.838, respectively. Conclusion BNP and NLR are independent risk factors of elderly patients of heart failure with pulmonary infection .The combined detection of BNP and NLR has predictive value for those patients.
