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.

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.

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.

Objective To construct the new diet intervention scheme of dyslipidemia of university teachers, discuss the effect of this plan on eating behavior change. Methods Choose two groups of college teachers in Harbin, who were hyperlipemia and had physical examinations from June to September, 2014. 44 teachers from one college were conducted the new dietary intervention as experimental group, 37 teachers from another college were the control group, used the usual method. Compared two groups before and after the intervention of dietary behavior and blood lipid. Results The experimental group′s dietary behaviors changed strongly after implement the new dietary intervention, the scores of DTS before the experiment (58.82 ± 18.47) points,3 months after the experiment (48.36 ± 14.25) points and 6 months after the experiment (44.18±14.92) points were statistically significant (F=21.308, P < 0.01). There was no statistically significant difference in control group (F = 1.129, P > 0.05), respectively (60.51 ± 16.91) points, (57.19 ± 16.35) points, (56.92 ± 21.35) points. After 6 months, the experimental group′s subjects of TC was (4.28±3.73) mmol/L, the control group was (6.23±1.04) mmol/L, the difference was statistically significant (t = 3.082, P < 0.05), there were no significant differences in TG, LDL-C and HDL-C of the two groups (P>0.05). Conclusions The new dietary guidance plan can effectively improve and maintain the dietary behavior in hyperlipidemia college teachers, and decrease the blood lipid level.

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

Objective To evaluate the functions of the left atrium using two-dimensional strain（2DS）echocardiography and left atrium volume index（LAVI）in the patients with hypertrophic cardiomyopathy（HCM）and explore its clinical value.Methods There were 37 patients with HCM and 35 healthy subjects enrolled in our study.Left atrial passive ejection fraction（LAPEF）and left atrial active ejection fraction（LAAEF）were calculated using Simpson＇s method.The analysis for atrial longitudinal peak systolic strain（S）,peak systolic stain rate（SRs）,peak early diastolic stain rate（SRe）and peak late diastolic strain rate（SRa）on the interatrial septum and the lateral wall of the left atrium were performed using 2DS echocardiography.Results LAPEF and LAAEF significantly decreased compared with those in the control group（P 0.05,P 0.01）.LAVI in HCM group increased compared with that of the control group（P 0.01）.S,SRs,SRe and SRa of the interatrial septum and the lateral wall were lower in patients with HCM than those in control group（P 0.05）.LAVI was negatively correlated to 2DS（r =0.73,P 0.05）.Conclusion The left atrial functions decreased in patients with HCM.2DS and LAVI are readily obtained parameters that provide unique data about global and segmental atrial functions.
