Objective To evaluate the relationship between cytotoxin-associated gene-A (CagA)seropositive of Helicobacter pylori (H .pylori )infection and risk of atherosclerotic cerebral infarction(ACI).Methods Related literatures were researched through literature retrieval ,literatures were obtained by uniformed criteria of inclusion and exclusion,and Meta analysis was performed with RevMan 4.2 software.Results A total of 10 literatures which met the inclusion criteria were retrieved,all were case-control study,case group included 907 studied subjects,and control group included 966 subjects;the included population were divided into Chinese subgroup and European Caucasian sub-group.Meta analysis of CagA seropositive of H .pylori infection and risk of ACI revealed that OR of the overall popula-tion,Chinese subgroup,and European Caucasian subgroup was 2.66(2.17-3.26),2.60(1.93-3.49),and 2.71(2.05-3.59)respectively;Meta analysis of CagA seronegative of H .pylori infection and risk of ACI revealed that OR of the overall population,Chinese subgroup,and European Caucasian subgroup was 0.74(0.49-1.10),0.81(0.45-1.48),and 0.64(0.37-1.09)respectively.The funnel plot and fail-safe number showed that there was no significant publication bias, the result was stable and reliable.Conclusion Chronic infection caused by CagA seropositive strains of H .pylori may be one of the risk factors of CAI,whether the eradication treatment of seropositive strains of H .pylori influences the process of atherosclerotic diseases like CAI needs to be further studied.

The human ovarian mucinous cystadenocarcinoma (hOMC) cells were co-cultured with antisense oligodeoxynucleotide (antisense ODN), nonsense ODN, and follicle-stimulating hormone (FSH) at different concentrations for the purpose of observing the effects of antisense ODN to FSH receptor (FSHR) on the proliferation and apoptosis of cultured hOMC cells in vitro. The inhibitory rates of growth were measured by using MTT method on the 2nd, 4th, 6th, 8th and 10th days after the interference of antisense ODN, nonsense ODN, and FSH, respectively. The apoptotic rates and the cell cycles were determined by means of flow cytometry, the apoptosis indexes were detected by using TUNEL, and the expression of caspase-3 was measured by using SP immunohistochemistry. Compared with that in the control group, the proliferative activity of hOMC cells was increased obviously in FSH groups (P<0.05 or P<0.01), decreased distinctly in antisense ODN groups (P<0.05 or P<0.01), and unchanged in nonsense ODN groups, respectively. Meanwhile, antisense ODN could significantly antagonize the FSH-promoted cell proliferative activity (P<0.01). Compared with those in the control group, the apoptotic rates and the expression of caspase-3 were dramatically increased in the mid-and high-dose antisense ODN groups (P<0.05 or P<0.01), while the number of cells in G(1)/G(0) phase was significantly decreased and that in S phase distinctly increased (P<0.01). There was no change in nonsense ODN groups (P>0.05). It was suggested that FSH may improve the development of hOMC cells. However, antisense ODN could inhibit proliferative activity and the FSH-promoted proliferative activity in hOMC cells, at the same time, antisense ODN could inhibit hOMC cell growth by inducing apoptosis.

Carotid atherosclerosis is an important pathogenesis of ischemic stroke.Inflammation plays a crucial role in the artery atherosclerotic genesis and development as well as its caused complications.Human CXC chemokine ligand 16 (CXCL16),as a novel chemokine,involves in the formation and development of atherosclerotic plaques.It may be associated with atherosclerotic stroke.

Applying cellular transplant methods in the treatment of peripheral nerve injury has become a new hot spot in tissue engineering and drawn much attention. Bone marrow stromal cells (BMSCs) grow fast and can be easily purified in vitro. Besides, they have the capability of differentiating into Schwann cells under specific conditions. For all the reasons above, BMSCs are considered good succedaneum of Schwann cells and new seed cells for tissue engineered peripheral nerve. In this review, the physiological functions and bionomics of Schwann cells and BMSCs are introduced, as well as various methods inducing BMSCs into nerve tissue cells and the foreground of the research.

ObjectiveTo investigate the application of the ratio of early diastolic peak velocity of mitral valve(E) and early diastolic peak velocity of mitral annular(Ea) on evaluating left ventricuiar diastolic function in patients with chronic heart failure.MethodsLeft atrial diameter(LAD),left ventricular end-diastolic diameter (LVEDd),interventricular septal thickness (IVST),left ventricular ejection fraction (LVEF),E and late diastolic peak speed of mitral valve (A) of 30 patients with diastolic heart failure(DHF,DHF group),30 patients with systolic heart failure(SHF,SHF group) and 30 healthy persons (control group) were detected by conventional echocardiography.E/A ratio and E-wave deceleration time (DT) were calculated.Early diastolic peak velocity of longitudinal septal and left ventricular lateral part of mitral annulus (Esep,Elat) were measured by tissue Doppler imaging (TDI).Ea and E/Ea ratio were calculated as well as the relevant analysis was made.Results ( 1 ) LAD and IVST in DHF group were significantly higher than those in control group [(44.90±8.31) mm vs.(30.87±3.48) mm,(9.43±2.18) nn vs.(8.17 ± 1.12)mm,P＜0.05].LVEDd in SHF group was obviously higher than that in control group and DHF group [(66.30 ± 10.21) mm vs.(44.77 ± 4.17) mm,(48.60 ± 8.85) mm,P＜0.05],and LVEF and DT were significantly lower than those in control group and DHF group(P ＜ 0.05 ).(2) Esep,Elat and Ea in DHF and SHF group were significantly lower than those in control group( P ＜ 0.01 ),and E/Esep,E/Elat and E/Ea ratios were obviously higher than those in control group (P ＜ 0.01 ).( 3 ) The level of B type natriuretic peptide (BNP) in DHF and SHF group was significantly higher than that in control group [(477.73 ± 722.76),(978.60 ± 825.04) ng/L vs.(29.23 ± 17.84) ng/L,P ＜ 0.05 ].The level of BNP in SHF group was significantly higher than that in DHF group (P＜0.05 ).(4) Multivariate linear regression analysis showed that NYHA classification and BNP were correlated with E/Ea ratio (P ＜ 0.05).(5) The area under curve (AUC) of E/Ea in diagnosing chronic heart failure was 0.984 (95％ CI:0.000-1.000).AUC of E/Ea in identifying DHF and SHF was 0.857(95％ CI:0.773-0.940).The sensitivity and specificity of E/Ea were much higher than those of E/A.Conclusions Chronic left ventricular systolic insufficiency is commonly combined with different-degree diastolic dysfunction.The evaluation of left ventricular diastolic function can be more simple and accurate combined with pulse wave Doppler and TDI.

Objective To evaluate the regional cardiac function for patients with coronary heart disease (CHD) with multiple tissue Doppler imaging (TDI) parameters in rest state and to discuss the value of regional cardiac function in diagnosing CHD.Methods Forty-seven patients with chief complain of chest pain underwent TDI examination.Maximum systolic velocity (Sm),maximum early diastolic velocity (Em),maximum late diastolic velocity (Am),isovoluminal contraction time (IVCT) and isovoluminal relaxation time(IVRT) of 16 segments of left ventricle were measured.All the patients underwent coronary angiography (CAG) at the same time.CHD was diagnosed by at least one coronary artery with no less than fifty percent diametric stenosis.Segments dominated by coronary artery with fifty to ninety and more than ninety percent diametric stenosis were defined as moderate and severe lesion segments respectively.Others were non-lesion segments.Results There was no significant difference of sex,age,heart rate,CHD risk factors,left ventricular ejection fraction (LVEF) and E/A among non-CHD (13 cases),one-lesion(11 cases),two-lesion (11 cases) and three-lesion (12 cases)(P ＞0.05).Compared with those in non-lesion segments (390sections),Sm,Em and Em/Am decreased and IVRT prolonged in both moderate lesion segments (162 sections) and severe lesion segments (144 sections) (P ＜ 0.01).IVCT prolonged only in severe lesion segments (P ＜0.05),but not in moderate lesion segments.If setting a criterion that no less than three segments with Sm ＜ 2.50 cm/s and IVRT ＞ 87 ms was for CHD diagnosis,the sensitivity,specificity,positive predictive value,negative predictive value and accuracy were 79.4％ (27/34),84.6％ (11/13),93.1％ (27/29),61.1％(11/18) and 80.9％(38/47).Conclusions In rest state,regional cardiac function of lesion segments in CHD patients shows changes of decreased systolic and diastolic velocity and prolonged isovoluminal time.Analyzing segmental cardiac velocity and time comprehensively may help to diagnose CHD.

Objective To evaluate the value of real-time three-dimensional echocardiography（RT3DE）to predict the long-term response to cardiac resynchronization therapy（CRT）.Methods Twenty-six patients with heart failure were scheduled for CRT.RT3DE was performed before and one year after the pacemaker implantation,and left ventricular（LV）dyssynchrony was defined as the maximum difference（Tmsv 16-Dif）and standard deviation（Tmsv 16-SD）when the minimum systolic volume of 16 segments was reached.Patients were divided into re-sponders and non-responders according to a reduction ≥15 % in LV end-systolic volume（LVESV）after CRT.Results Seventeen patients（65.4 %）were classified as responders.Compared with non-responders,the responders demonstrated a significant increase in LV ejection fraction,and reduction in Tmsv 16-SD.Tmsv 16-SD was a determinant factor for Δ LVESV ≥15%.Tmsv 16-SD 〉3.5% could be employed to evaluate the short-term response to CRT with 80 % sensitivity and 77 % specificity.Conclusions CRT can increase the LV systolic function and synchrony.RT3DE is highly predictive for long-term response to CRT
