Objective To investigate the impact of hs-CRP and IVUS on major adverse cardiac event in patients who after coronary artery intermediate lesions stent implantation.Methods 82 patients with clinical diagnosis of coronary heart disease who had a segmental stenosis degree is 40％ ～ 70％ in one major coronary artery on coronary angiography,all of the patients do intravascular ultrasound,patients had minimal lumen area(MLA) of intermediate lesions ≤ 4mm2( the left main coronary artery)or≤ 6mm2( left main coronary artery) who received percutaneous coronary intervention(PCI),and the patients were divided into 2 groups,hs-CRP rise group(≥3mg/L) and hs-CRP normal group(＜3mg/L),compared the rate between the two groups in hospital and follow up periods by typical angina,nonfatal myocardial infarction,cardiac death and target-vessel revascularization and other major adverse cardiac events (MACE).Results The rate on major adverse cardiac event in hs-CRP rise group was significantly higher than the normal group(P ＜0.01 );the restenosis rate in hs-CRP rise group higher than hs-CRP normal group(P ＜0.01 ).Conclusion hs-CRP could predict the rate on major adverse cardiac event in patients with after coronary artery intermediate lesions stent implantation,the patients of hs-CRP rise group should strengthen antiplatelet,anti-inflammatory treatment etc.

Objective To optimize the parameters for the diffusion tensor imaging (DTI)of the ulnar nerve in elbow.Methods 5 groups of DTI sequences with different b values and numbers of diffusion gradient directions (NDGDs)were used to collect ulnar nerve images from 13 volunteers,and then the diffusion tensor tractography (DTT)was established.The fractional anisotropy (FA),apparent diffusion coefficient (ADC),length of ulnar nerve fiber and DTI image quality were compared under different imaging parameters. Results DTI results for 18 normal ulnar nerves were included in the study.Under different imaging conditions,FAs showed no significant differences.With constant NDGDs,increasing b value decreased both image quality and ADCs of the ulnar nerve.NDGDs had no significant effects on ADCs or image quality.When b=1 000 s/mm2 and NDGDs=20,the length of the ulnar nerve fiber was the longest and DTT had the best subjective scoring in image quality.Conclusion b=1 000 s/mm2 and NDGDs=20 is recommended for DTI of elbow ulnar nerve,so as to obtain high image quality and stable observing targets.

AIM:To investigate the changes of connexin 43 (Cx43) via establishing a model of sympathomi-metic atrial fibrillation ( AF) .METHODS:The mongrels ( n=15) were randomly divided into control group , rapid atrial pacing (RAP) group and isoprenaline (ISO) perfusion+RAP group (ISO+RAP group).All mongrels’ hearts were taken out rapidly by median sternotomy to establish the cardiac model with Langendorff perfusion in vitro.The atrial effective re-fractory period ( AERP) and AF inducability were tested .The expression and distribution of tyrosine hydroxylase ( TH) were analyzed by immunohistochemistry .Total protein level of Cx 43 and phosphorylation of Cx 43 were determined by West-ern blot.The distribution of Cx43 were also observed by immunofluorescence staining .The cell apoptosis was analyzed by TUNEL staining.The generation of reactive oxygen species ( ROS) in the mitochondria was measured by fluorescence spec-trophotometry .RESULTS:No significant change of AERP was found between control group and RAP group , while that in ISO+RAP group was significantly decreased (P<0.05) and induced AF.Compared with control group, the expression of TH, apoptotic index and the generation of ROS increased gradually (P<0.05), while the content of Cx43 decreased grad-ually both in the total protein and the phosphorylation levels in RAP group and ISO +RAP group (P<0.05).The fluores-cence intensity of Cx43 was also attenuated and Cx43 were lateralized apparently in RAP group , while Cx43 were character-ized as punctate distribution in ISO +RAP group.CONCLUSION:Sympathetic nerves may activate autophagosome at in-tercalated discs and trigger cell apoptosis , resulting in remodeling and downregulation of Cx 43 via oxidative stress , thus having effects on mediating and maintaining AF .

Objective: To explore the relationship between NLRP3 inflammasome and atrial fibrillation (AF) by examining peripheral blood level of NLRP3 inlfammasome and other inlfammatory factors in relevant patients.
Method: A total of 60 AF patients were enrolled and divided into 2 groups: Paroxysmal AF (PAF) group and Non-paroxysmal atrial fibrillation (nPAF) group, n=30 in each group;in addition, there was a Control group including 26 healthy subjects from physical examination. NLRP3 expression in peripheral blood mononuclear cells (PBMCs) was measured by lfow cytometry;blood levels of IL-1β, IL-6, CRP and NT-proBNP were detected by ELISA. The correlations among different factors were studied by liner regression analysis and the differences were compared among groups.
Result:①Compared with Control group, PAF and nPAF groups had increased PBMCs level of NLRP3 and blood levels of IL-1β, IL-6, CRP, NT-proBNP, P<0.05, while NLRP3 level was similar between PAF group and nPAF group, P>0.05.②PAF and nPAF groups showed elevated blood level of NT-proBNP than Control group, P<0.05. ③PBMCs level of NLRP3 was positively related to left atrial diameter (r=0.579, P<0.05) and negatively related to left ventricular ejection fraction (r=-0.490, P<0.05) in both AF groups.
Conclusion: ① NLRP3 inflammasome was closely related to AF, which may provide a therapeutic target for AF treatment. ② AF was closely related to inflammatory response. ③ Downstream product of NLRP3 may cause the inlfammatory response which could induce the occurrence, development and maintenance of AF in relevant patients.

Objective To provide supportive evidences for the diagnosis of primary major depres-sive disorder (MDD) by analyzing the alterations of proinflammatory cytokines such as IL-1α, IL-6, IL-18, TNF-αas well as the total complement activity (CH50) in serum samples.Methods Hamilton Depression Rating Scale ( HAMD) was used to rate the severity of depression with the patients who were diagnosed as primary MDD.Enzyme-linked immunosorbent assay (ELISA) was used to detect the levels of IL-1α, IL-6, IL-18 and TNF-αand the CH50 in serum samples from 49 patients and 40 healthy subjects .Results Pa-tients with MDD showed significantly different levels of IL-6, IL-18, TNF-αand CH50 in serum samples as compared with that in healthy subjects (P<0.05).No significant difference with the level of IL-1αwas ob-served between the patients with MDD and healthy subjects (P>0.05).There were significant gender differ-ences with levels of IL-1αamong the patients with MDD (P<0.05).However, no significant differences with the levels of IL-6, IL-18, TNF-αand CH50 were found between male and female patients (P>0.05). Conclusion The changes of CH50 and certain proinflammatory cytokines such as IL-6, IL-18 and TNF-αmight be involved in the progression of MDD , suggesting the possibility of using them as indicators for the di-agnosis of MDD.

Based upon the measure of depression as defined by Hamilton depression scale (HAMD)scores ＞ 17,120 patients with chronic obstructive pulmonary disease (COPD) were classified into 2 groups:COPD patients with or without depression.According to the mini-mental state examination (MMSE),the cognitive functions of all patients were evaluated.Meanwhile,oxygen saturation and pulmonary function were measured by blood gas analyzer and spirometer respectively.Fifty-four COPD patients were complicated with depression.HAMD scores were significantly negatively correlated with oxygen saturation and pulmonary function (P ＜0.05).Multiple regression analysis revealed that gender,oxygen saturation and MMSE scores were risk factors of depression (P ＜ 0.05).MMSE scores decreased more obviously in the COPD patients with depression and were positively correlated with oxygen saturation (P ＜ 0.01).A negative correlation existed between MMSE scores and HAMD scores (r =-0.549,P ＜ 0.05).

Objective To study the association between the plasma homocysteine level and coronary artery disease(CAD), and the methylenetetrahydrofolate reductase (MTHFR) A1298C polymorphism, the methionine synthase (MS) A2756G polymorphism and their associations to the plasma homocysteine level and CAD in the elderly . Methods One hundred and twenty-nine elderly patients with CAD documented by coronary angiogram and 48 elderly patients with normal coronary angiographic results were included in this study. Plasma homocysteine level were measured by fluorescence polarization immunoassay (FPIA) method and polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) method was used to analyse the MTHFR A1298C and MS A2756G genotypes. Results The plasma homocysteine level was significantly higher in CAD group than that in the control group〔(16.2?8.6) ?mol/L vs (12.7?5.0) ?mol/L,P0.05);the prevalence of MTHFR 1298CC homozygous in the CAD patients was significantly less than that in the control group (3.1% vs 14.6%, P

Objective To explore the relationship between genetic variation in PAF-AH V279F and coronary heart disease among Han population in Beijing.Methods A case-control study was held which enrolled 124 patients with coronary heart disease and 103 normal subjects.The genotype of PAF-AH V279F was determined with allele-specific polymerase chain reaction(AS-PCR)method. Results The highest frequency of PAF-AH V279F genetic variation was VV genotype(92.2%),the next was VF genotype(5.8%)and the lowest was FF genotype(2.0%)among the studied Han population in Beijing.In the coronary heart disease group the frequency of 279 V→F carriers was significantly higher than in the control group(19.3% vs.7.8%,P＜0.05)and F allele frequency was also higher(12.1% vs.4.9%,P＜0.01).Among the coronary heart disease group,the V279F variation frequency and the F allele frequency were significantly higher in patients with myocardial infarction than in those without myocardial infarction(27.3% vs.13.0%,17.3% vs.8.0%,both P＜0.05).In multiple logistic regression analysis,the odds ratio(OR)of V279F genetic variation for coronary heart disease was 1.919(95% CI:1.448-2.544,P=0.033).Conclusions The PAF-AH V279F genetic variation may be a novel genetic marker for high risk of coronary heart disease.
